Treatment for Epstein-Barr Virus-associated uveitis confirmed by polymerase chain reaction: Efficacy of Anti-Viral Agents and a literature review.
There are still many research challenges and unanswered questions in relation to Epstein-Barr virus-associated uveitis. These include the presence of Epstein-Barr virus (EBV) DNA in asymptomatic patients, its pathogenicity in the uveitis eye, and the role of antiviral therapy for EBV-associated intraocular inflammation.. This was a retrospective review of prospectively collected data from the Ophthalmology Department, Rajavithi Hospital between 2015 and 2020. A qualitative assay using multiplex real-time PCR was performed to detect pathogen genes from specimens obtained from a total of 344 patients. The main outcome measure was treatment success defined by clinical improvement and absence of viral DNA confirmed by PCR.. Of the 35 cases, 24 with complete data were enrolled in the study, including 22 with post-treatment PCR results. Sixty-seven percent were HIV-infected, and other plausible causes or coinfection with other pathogens were found in 75% of patients. Cytomegalovirus (38%) was the most common co-infecting pathogen. The most commonly employed regimen was a combination of systemic acyclovir and intravitreal ganciclovir injection (58%). Of the 22 cases who had post-treatment PCR results, absence of detection of the virus by PCR in the intraocular fluid after treatment was demonstrated in 73% of patients.. Patients with EBV infection can be simultaneously co-infected with other pathogens. Systemic acyclovir and ganciclovir achieved clinical improvement in most cases, and EBV infection was cured in the majority of patients.

EPSTEIN-BARR VIRUS ACUTE RETINAL NECROSIS IN AN IMMUNOCOMPETENT HOST.
To describe a case of Epstein-Barr virus (EBV)-associated acute retinal necrosis (ARN) in an immunocompetent patient and to summarize the clinical features of published molecularly confirmed EBV-ARN cases.. Case report and literature review.. An 83-year-old immunocompetent woman with unilateral ARN presented with visual acuity of light perception. Oral valacyclovir was started. One week later, vitrectomy was conducted for worsening inflammation. Intraoperatively, a severe confluent necrotizing retinitis and occlusive vasculitis involving all four quadrants of posterior and peripheral retina were noted. Vitreous polymerase chain reaction was exclusively positive for EBV. Other autoimmune, infective, and hematological work-up was negative. The retinitis resolved 3 months later, but with significant macular and generalized retinal atrophy, visual acuity remained light perception. From the literature, there are four EBV-ARN cases (six eyes) diagnosed based on polymerase chain reaction or fluorescence in-situ hybridization of vitreous or retinal samples. All patients were immunocompromised or on immunosuppressive treatment. Presenting visual acuity was light perception or worse in 3/6 eyes. Three patients received systemic acyclovir-based therapy. Vitrectomy was performed in 4/6 eyes between 4 and 8 weeks from disease onset. All cases had involvement of the posterior and peripheral retina. Retinal detachment occurred in 2/6 eyes, and final visual acuity was no light perception in 3/6 eyes.. This case expands the clinical spectrum of EBV-ARN to include infection in immunocompetent hosts. Epstein-Barr virus-ARN seems to be characterized by a global peripheral and posterior fulminant retinitis, with adverse visual acuity outcomes despite systemic acyclovir-based therapy. The benefits of adjunctive intravitreal foscarnet, systemic steroids, and early vitrectomy may warrant further investigation.

Fulminant Epstein-Barr virus-associated hemophagocytic syndrome in a renal transplant patient and review of the literature.
We describe a rare fulminant case of Epstein-Barr virus-associated hemophagocytic syndrome (HPS) in a 37-year-old female renal transplant patient, indistinguishable from severe sepsis clinically and in the laboratory. HPS involves rapidly escalating immune system activation, resulting in a cytokine cascade, which can, especially in immunocompromised patients, lead to multi-organ failure, and even death. Thirty-two Herpesviridae-associated HPS cases in renal transplant patients have been reported and are reviewed. Overall mortality is 47% (15/32 cases).

[Encephalitis due to the Epstein-Barr virus: a description of a clinical case and review of the literature].
INTRODUCTION. Infection by the Epstein-Barr virus (EBV) -either as a primary infection, a reactivation or an active chronic infection- can give rise to several clinical forms of involvement of the central nervous system. We report a case of encephalitis due to EBV produced by viral reactivation in an immunocompetent patient which initially mimicked, from the clinical and electroencephalographic point of view, encephalitis due to type 1 herpes simplex virus (HSV-1). CASE REPORT. A 51-year-old male who had reported the presence of dorsal herpes zoster some days earlier. The patient visited the emergency department after suffering a holocranial oppressive headache and febricula for seven days; 24 hours before admission to hospital, he was suffering from drowsiness and language disorder. The neurological examination revealed stiffness in the back of the neck and dysphasia. An analysis of the cerebrospinal fluid revealed pleocytosis (422 cells/mm(3)) with 98% of mononuclear cells and normal protein and glucose concentration levels in cerebrospinal fluid. Magnetic resonance imaging of the brain and electroencephalogram readings were normal with periodic lateralised epileptiform discharges in the left temporal region. Intravenous acyclovir treatment was initiated, but renal failure meant it had to be changed to oral valaciclovir with clinical resolution and improvement of the liquoral parameters. Polymerase chain reaction in the cerebrospinal fluid was positive for EBV and negative for the other neurotropic viruses. In blood, the serology test for EBV with IgG was positive, while IgM and heterophile antibody tests were negative. CONCLUSIONS. EBV infection can give rise to acute disseminated encephalomyelitis or affect several locations in the central nervous system, especially the cerebellum. Clinical pictures mimicking HSV-1 are less frequent. When encephalitis is related to viral reactivation, precipitating factors can be detected, as in our case.. Encefalitis por el virus de Epstein-Barr: descripcion de un caso clinico y revision de la bibliografia.. Introduccion. La infeccion por el virus de Epstein-Barr (VEB) puede dar lugar –tanto como primoinfeccion, reactivacion o infeccion cronica activa– a varias formas clinicas de afectacion del sistema nervioso central. Presentamos un caso de encefalitis por VEB producido por reactivacion virica en un paciente inmunocompetente, que inicialmente simulaba, desde el punto de vista clinico y electroencefalografico, una encefalitis por virus herpes simple tipo 1 (VHS-1). Caso clinico. Varon de 51 años con antecedente de herpes zoster dorsal en los dias previos. Acudio a urgencias por un cuadro de siete dias de duracion de cefalea opresiva holocraneal y febricula; 24 horas antes de su ingreso, padecia somnolencia y alteracion del lenguaje. En la exploracion neurologica presentaba rigidez nucal y disfasia. En el liquido cefalorraquideo se evidencio pleocitosis (422 celulas/mm3) con un 98% de mononucleares, y proteinorraquia y glucorraquia normales. Resonancia magnetica cerebral normal y electroencefalograma con descargas epileptiformes lateralizadas periodicas en la region temporal izquierda. Se trato con aciclovir intravenoso; una insuficiencia renal motivo su cambio a valaciclovir oral con resolucion clinica y mejoria de los parametros licuorales. La reaccion en cadena de la polimerasa en el liquido cefalorraquideo fue positiva para VEB y negativa para el resto de virus neurotropos. En sangre, la serologia para VEB con IgG resulto positiva, y negativa con IgM y anticuerpos heterofilos. Conclusiones. La infeccion por VEB puede dar lugar a una encefalitis aguda diseminada o afectar a varias localizaciones del sistema nervioso central, principalmente el cerebelo. Menos frecuentes son los cuadros imitadores de VHS-1. Cuando la encefalitis se relaciona con reactivacion viral pueden detectarse, como en nuestro caso, factores precipitantes.

Antiviral treatment for severe EBV infections in apparently immunocompetent patients.
Infectious mononucleosis usually runs a mild self-limiting course. Complications arise rarely and when so, corticosteroids are the mainstay of their treatment. The role of antivirals in the management of severe EBV infections is debatable.. We sought to review the usage of antivirals for severe EBV infection in apparently immunocompetent patients. For this reason a search in PubMed and Scopus was performed for the time period from 1982 to 2009.. 45 patients with severe manifestations of infectious mononucleosis received antivirals (as an adjunct to steroids in 26 of them). Specifically 21 patients with CNS involvement (meningoencephalitis, cerebellitis), 4 with peripheral nervous system involvement (Guillain-Barré, myeloradiculitis, facial nerve palsy), 5 with hepatitis and 15 with other afflictions (including adult respiratory distress syndrome, thrombocytopenia, aplastic anemia, acute renal failure, ulcerations, myocarditis, and frosted branch vasculitis) received antiviral medications. Thirty-nine out of these 45 patients had a favourable outcome (27 were cured and 12 showed clinical improvement) while 6 patients died. The most commonly prescribed antiviral regimen was acyclovir monotherapy (35 patients). Three patients received combinations of acyclovir with other antivirals and 1 received famciclovir. Three patients received ganciclovir monotherapy, 1 ganciclovir plus foscarnet, 1 foscarnet and 1 vidarabine.. The available data derive from case reports and case series and thus the deduction of conclusions regarding the effect, if any, of antiviral treatment is debatable. However, physicians may consider using antiviral agents in severe manifestations of EBV infections in immunocompetent patients as an adjunct to steroid treatment.

Viral infections affecting the skin in organ transplant recipients: epidemiology and current management strategies.
Viral skin infections are common findings in organ transplant recipients. The most important etiological agents are the group of human herpesviruses (HHV), human papillomaviruses (HPV), and molluscum contagiosum virus. HHV that are important in this group of patients are herpes simplex virus (HSV) types 1 and 2, varicella-zoster virus (VZV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), HHV-6 and -7, and HHV-8, which causes Kaposi sarcoma (KS). HSV infections are characterized by their ability to establish latency and then reactivate at a later date. The most common manifestations of HSV infection in organ transplant recipients are mucocutaneous lesions of the oropharynx or genital regions. Treatment is usually with acyclovir, valaciclovir, or famciclovir. Acyclovir resistance may arise although the majority of acyclovir-resistant strains have been isolated from AIDS patients and not organ transplant recipients. In such cases, alternatives such as foscarnet, cidofovir, or trifluridine may have to be considered. VZV causes chickenpox as well as herpes zoster. In organ transplant recipients, recurrent herpes zoster can occur. Acute chickenpox in organ transplant patients should be treated with intravenous acyclovir. CMV infection occurs in 20-60% of all transplant recipients. Cutaneous manifestations, which include nonspecific macular rashes, ulcers, purpuric eruptions, and vesiculobullous lesions, are seen in 10-20% of patients with systemic infection and signify a poor prognosis. The present gold standard for treatment is ganciclovir, but newer drugs such as valganciclovir appear promising. EBV is responsible for some cases of post-transplant lymphoproliferative disorder, which represents the greatest risk of serious EBV disease in transplant recipients. HHV-6 and HHV-7 are two relatively newly discovered viruses and, at present, the body of information concerning these two agents is still fairly limited. KS is caused by HHV-8, which is the most recently discovered lymphotrophic HHV. Iatrogenic KS is seen in solid-organ transplant recipients, with a prevalence of 0.5-5% depending on the patient's country of origin. HPV is ubiquitous, and organ transplant recipients may never totally clear HPV infections, which are the most frequently recurring infections in renal transplant recipients. HPV infection in transplant recipients is important because of its link to the development of certain skin cancers, in particular, squamous cell carcinoma.

A six-month trial of valacyclovir in the Epstein-Barr virus subset of chronic fatigue syndrome: improvement in left ventricular function.
This study was designed to determine safety and efficacy of a 6-month trial of valacyclovir in single-virus Epstein-Barr virus (EBV) persistent infection. Phase I of this study used four specific criteria to define a subset of patients with chronic fatigue syndrome (CFS). In the second phase, myocardial dynamics were measured by MUGA rest/stress radionuclide ventriculographic (RVG) examinations pre- and posttreatment with valacyclovir. In phase I, a trial was performed in 19 consecutive CFS patients with the following diagnostic conditions: patients met criteria for diagnosis of CFS; they had had CFS for less than 1 year. They demonstrated repetitively abnormal oscillating T waves (ischemic or flat) at 24-h Holter monitoring; and they had elevated serum IgM antibody titers to EBV viral capsid antigen and/or total diffuse early antigen as measured by the enzyme-linked immunosorbent assay method. The treatment group comprised 10 CFS patients with no serum antibodies to human cytomegalovirus, but the control group (nine CFS patients) had, additionally, high titers of serum antibodies (IgG) to conformational structural antigens of human cytomegalovirus. Both the parallel treatment and control CFS groups received valacyclovir 1.0-1.5 gm q.6.h. for 6 months. This valacyclovir dose achieved serum acyclovir C(max) of > 7 microm and high antiviral activity versus EBV (IC(50) of 4.4-13.3 m). In phase II, six additional CFS patients met the same four criteria as the 19 CFS patients in phase I. They had, however, been ill for a mean of 55.8 months. Thus, 25 CFS patients comprise this study. The studies were carried out at a single outpatient practice in Birmingham, MI, U.S.A. Before initiating valacyclovir, and after 6 months of treatment, clinical and laboratory observations were made. The CFS Energy Index point score (Table I) was used to record each CFS patient's functional capacity at baseline and after 1, 3 and 6 months of valacyclovir. Energy Index point scores, as well as EBV and human cytomegalovirus serum antibody titers were assessed. In the second phase, left ventricular dynamics were repeated after 6 months of treatment with valacyclovir. We concluded that the 16 CFS patients (included in both phases of this study) with EBV-persistent infection (EBV single-virus subset) are improved after 6 months of continuous pharmacokinetic dosing with valacyclovir. Nine CFS patients with EBV/human cytomegalovirus co-infection did not benefit from 6 months of similar t Topics: Acyclovir; Chi-Square Distribution; Clinical Trials as Topic; Epstein-Barr Virus Infections; Fatigue Syndrome, Chronic; Herpesvirus 4, Human; Humans; Valacyclovir; Valine; Ventricular Function, Left | 2002 |
Biliary stricture secondary to donor B-cell lymphoma after orthotopic liver transplantation.
Biliary complications after orthotopic liver transplantation (OLT) lead to considerable morbidity and occasional mortality after surgery. Bile duct strictures secondary to localized lymphoproliferative disorder of the porta hepatis is rare, with only 12 cases reported in the English literature. Posttransplant lymphoproliferative disorder develops in up to 9% of liver allograft recipients. We describe 2 adult patients who developed Epstein-Barr virus-associated localized B-cell lymphoma of donor-tissue origin confined to the porta hepatis 3 and 5 months after OLT. Both patients were administered cyclosporine (CyA) and prednisone as primary immunosuppression. One patient was administered basiliximab as induction therapy. Neither patient had CyA trough levels greater than 250 ng/mL. Both patients were treated with a hepatojejunostomy, 75% reduction in immunosuppression therapy, and acyclovir. One patient had complete involution of the tumor, and the second patient had an 80% reduction of the tumor at the 2-year follow-up visit. This report illustrates the need to consider localized lymphoma post-OLT as a cause of obstructive jaundice even within the first 6 months after surgery. Aggressive reduction of immunosuppression in conjunction with acyclovir remains a highly effective therapy.

B cell lymphoproliferative disorders following hematopoietic stem cell transplantation: risk factors, treatment and outcome.
Twenty-six cases of B cell lymphoproliferative disorder (BLPD) were identified among 2395 patients following hematopoietic stem cell transplants (HSCT) for which an overall incidence of BLPD was 1.2%. The true incidence was probably higher, since 9/26 of the diagnoses were made at autopsy. No BLPD was observed following autologous HSCT, so risk factor analyses were confined to the 1542 allogeneic HSCT. Factors assessed were HLA-mismatching (> or = 1 antigen), T cell depletion (TCD), presence of acute GvHD (grades II-IV), donor type (related vs unrelated), age of recipient and donor, and underlying disease. Factors found to be statistically significant included patients transplanted for immune deficiency and CML, donor age > or = 18 years, TCD, and HLA-mismatching, with recipients of combined TCD and HLA-mismatched grafts having the highest incidence. Factors found to be statistically significant in a multiple regression analysis were TCD, donor age and immune deficiency, although 7/8 of the patients with immunodeficiencies and BLPD received a TCD graft from a haploidentical parent. The overall mortality was 92% (24/26). One patient had a spontaneous remission, but subsequently died >1 year later of chronic GVHD. Thirteen patients received therapy for BLPD. Three patients received lymphocyte infusions without response. The only patients with responses and longterm survival received alpha interferon (alphaIFN). Of seven patients treated with alphaIFN there were four responses (one partial and three complete). These data demonstrate that alphaIFN can be an effective agent against BLPD following HSCT, if a timely diagnosis is made.

Long-term administration of valacyclovir reduces the number of Epstein-Barr virus (EBV)-infected B cells but not the number of EBV DNA copies per B cell in healthy volunteers.
Epstein-Barr virus (EBV) establishes a latent infection in B cells in the blood, and the latent EBV load in healthy individuals is generally stable over time, maintaining a "set point." It is unknown if the EBV load changes after long-term antiviral therapy in healthy individuals. We treated volunteers with either valacyclovir (valaciclovir) or no antiviral therapy for 1 year and measured the amount of EBV DNA in B cells every 3 months with a novel, highly sensitive assay. The number of EBV-infected B cells decreased in subjects receiving valacyclovir (half-life of 11 months; P = 0.02) but not in controls (half-life of 31 years; P = 0.86). The difference in the slopes of the lines for the number of EBV-infected B cells over time for the valacyclovir group versus the control group approached significance (P = 0.054). In contrast, the number of EBV DNA copies per B cell remained unchanged in both groups (P = 0.62 and P = 0.92 for the control and valacyclovir groups, respectively). Valacyclovir reduces the frequency of EBV-infected B cells when administered over a long period and, in theory, might allow eradication of EBV from the body if reinfection does not occur.

Valtrex therapy for Epstein-Barr virus reactivation and upper respiratory symptoms in elite runners.
The aim of the study was to examine the effectiveness of prophylactic administration of the antiviral agent Valtrex for control of Epstein-Barr virus (EBV) reactivation and upper respiratory symptoms in elite distance runners.. Twenty elite male distance runners were randomized into a 4-month double-blind, placebo-controlled cross-over trial. Saliva samples were collected weekly and mucosal immune status assessed by measurement of secretory IgA (SIgA) using an enzyme-linked immunosorbent assay (ELISA). EBV reactivation was monitored at the same time by detection of EBV in saliva using a quantitative real-time polymerase chain reaction. The initial EBV status of the runners was determined by detecting EBV antibodies in serum using an ELISA. Upper respiratory symptoms were recorded using self-reporting illness logs.. There was no evidence of any marked change in maximal oxygen uptake (P = 0.86), training volume (P = 0.30), or mucosal immunity (P = 0.21) over the study period. Valtrex treatment resulted in an 82% reduction in the detectable EBV load in saliva for EBV seropositive runners compared with the placebo treatment (P = 0.04). The incidence of upper respiratory symptoms was not reduced by Valtrex treatment.. The prophylactic administration of Valtrex reduced EBV reactivation but was not an effective intervention strategy for limiting upper respiratory symptoms in this cohort of elite distance runners. The upper respiratory symptoms in the distance runners could not be directly attributed to infection and may be of a noninfectious inflammatory nature.

Pharmacokinetics and safety of valaciclovir in children with Epstein-Barr virus illness.
Valaciclovir has in vitro activity against Epstein-Barr virus (EBV) and, because of improved absorption with higher achievable serum concentrations, may be more effective than aciclovir in the treatment of EBV. No studies to date have evaluated the efficacy, safety or proper dosing of valaciclovir in children for the treatment of EBV infection. The objectives of this study were to determine the pharmacokinetics and safety of valaciclovir tablets and suspension in children with EBV illness.. 24 children with EBV illness were randomised to receive valaciclovir suspension 10 mg/kg or 20 mg/kg; eight children subsequently were crossed over and also received valaciclovir 500 mg tablets. Doses of either suspension or tablets were administered every 8 hours for four doses, and pharmacokinetic studies were performed to determine aciclovir serum concentrations. Samples for drug assay were obtained at 0, 0.5, 1, 2, 4, 6, 8 and 24 hours. Samples were assayed by high performance liquid chromatography (HPLC) methods and aciclovir pharmacokinetics determined using non-compartmental analysis.. Valaciclovir pharmacokinetic parameters (mean +/- SD) in children who received tablets and suspension (normalised to 500 mg dose) were: maximum serum concentration (C(max)) 3.16 +/- 1.30 and 2.42 +/- 0.74 mg/L, time to maximum serum concentration (t(max)) 1.88 +/- 0.99 and 1.31 +/- 0.53 hours, half-life (t 1/2) 1.72 +/- 0.41 and 1.94 +/- 0.60 hours, apparent total systemic clearance (CL/F) 20.01 +/- 6.61 and 15.58 +/- 3.34 ml/min/kg, volume of distribution/bioavailability (Vd/F) 3.04 +/- 1.26 and 2.58 +/- 0.81 L/kg, and area under the concentration-time curve (AUC) 10.13 +/- 3.47 and 8.59 +/- 2.52 mg x h/L, respectively. There were no statistically significant differences in the pharmacokinetics of valaciclovir tablets versus suspension. The relative bioavailability of the valaciclovir tablets compared with the suspension was 115 +/- 32%. Valaciclovir was well tolerated, with gastrointestinal disturbances and headache being the most common adverse effects in a small number of subjects.. Valaciclovir is absorbed and achieves concentrations in children that appear to be effective for the treatment of herpes lesions. The pharmacokinetics of valaciclovir suspension and tablets are similar, and the pharmacokinetics of aciclovir after administration of valaciclovir to children are similar to historical observations of aciclovir pharmacokinetics in adults. Valaciclovir has a good safety profile and was well tolerated after oral administration in this group of children.

Post-Epstein-Barr Virus Acute Cerebellitis in an Adult.
BACKGROUND Acute cerebellitis in adults is a rare disease. The etiology is unknown but postulated to be due to primary infection or para-infection. Different presentations have been reported, which complicates the diagnosis process. CASE REPORT We report the case of a young man who presented with headache, vomiting, and vertigo. He was found to have ataxia and cerebellar signs, bradycardia magnetic resonance imaging (MRI) of the brain showed acute cerebellitis, and cerebrospinal fluid (CSF) studies showed lymphocytosis. Further investigations showed the presence of Epstein-Barr virus (EBV) immunoglobulin M (IgM) and IgG. His symptoms resolved completely with corticosteroid and antiviral treatments. CONCLUSIONS Acute cerebellitis can present in various ways. Bradycardia, along with neurological deficits, should raise the suspicion of acute cerebellitis.

Epstein-Barr virus-related encephalitis in a young woman: A case report.
Although infectious mononucleosis due to Epstein-Barr virus (EBV) is a common disease among young individuals, central nervous system (CNS) complications are rare. In this report, we describe a case of CNS complications caused by EBV in a previously healthy young woman. She presented to our hospital with a 9-day history of headache and sore throat, followed by the development of fever and facial edema 6 days prior to admission. On Day 2 of admission, she was confused (Glasgow Coma Scale score: 10 points) and had fever, muscle weakness in her right arm and leg, stiff neck, and roving eye movement. We detected EBV in a cerebrospinal fluid (CSF) sample using a polymerase chain reaction (PCR) test. The magnetic resonance imaging of her brain revealed dural enhancement and right parietal and temporal lobe lesions. She was treated with acyclovir and high-dose steroid therapy. She responded well to treatment, recovered without neurologic sequelae, and was discharged home on Day 12. Our experience suggests that PCR detection of EBV DNA in CSF may be useful in diagnosing EBV encephalitis and that prognosis may be associated with an area of the brain that is affected and the time from symptom onset to starting treatment.

[Autoimmune hepatitis following acute severe Epstein-Barr virus hepatitis].
Non-alphabetical hepatitis (Epstein Barr virus -EBV-, cytomegalovirus -CMV-, Herpes simplex virus -HSV-, varicella zoster virus -VZV-etc.) may be a mode of revelation of several underlying chronic liver diseases including autoimmune hepatitis (HAI). We report a peculiar case of acute EBV hepatitis, revealing type I autoimmune hepatitis confirmed by liver biopsy through puncture in a female patient on breast cancer treatment. The study involved a 29-year-old female patient on breast cancer treatment scheduled to receive radiotherapy and chemotherapy, hospitalized for acute severe hepatitis (fever with jaundice, hypertransaminasemia (normal AST level 47 and normal ALT level 23 and prothrombin activity 25%). The test for viral hepatitis A, B, C, and E was negative and subhepatic veins were free on doppler. Non-alphabetical hepatitis was suspected based on fever with jaundice. Patient's assessment showed recent EBV infection diagnosed on the basis of the presence of anti-VAC IgM/G and anti-EBNA Ab IgG. The patient received acyclovir for 10 days. Progression was marked by ascites. The diagnosis of autoimmune hepatitis was retained based on laboratory tests (gamma peak on serum protein electrophoresis and positive anti-nuclear antibodies) and histological examination. Clinical-biological remission was obtained with corticosteroid therapy. EBV infections should be investigated in immunocompromised patients with fever in the clinical course of acute hepatitis. Practitioners should also suspect it in patients with persistent cytolysis following an infectious episode in order to prevent the occurrence of autoimmune hepatitis, in particular in female patients, in a context of self-immunity and negative serological tests for alphabetical viral hepatitis.

Hypertrophic chronic pachymeningitis associated with Epstein-Barr virus reactivation: a case report.
Hypertrophic pachymeningitis is a rare inflammatory condition characterized by the thickening of the dura mater. We describe a patient who presented with intractable headache and complex cranial nerve palsy. Hypertrophy of the frontal dura was accompanied by pleocytosis and detection of Epstein-Barr virus (EBV) by PCR in cerebrospinal fluid. Clinical symptoms gradually improved after acyclovir and corticosteroid treatment, whereas dural pathology remained unchanged on neuroimaging. This case points at an expansion of the spectrum of neurological manifestations for EBV.

An uncommon case of herpetic esophagitis in a small child with allergic rhinitis: A case report and literature review (CARE compliant).
Herpetic esophagitis (HE) is a common condition in immunosuppressed patients, but a rare entity in immunocompetent patients affecting especially male teenagers and young adults.. We report the case of a 5-year-old male patient, with a history of allergic rhinitis admitted in our clinic for acute onset fever refractory to antipyretics, chest pain, anorexia, refusal of solid food, accepting only small amounts of fluids, odynophagia, and epigastric pain. The clinical exam revealed severe malaise, pallor, decreased skin turgor, abdominal epigastric tenderness, heartburn at palpation within the epigastric area. The laboratory tests showed leukocytosis, monocytosis, hypoglycaemia, and elevated inflammatory biomarkers.. The serology tests for human immunodeficiency virus (HIV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), and herpes simplex virus (HSV) were negative, except for immunoglobulin G (IgG) anti-EBV which was positive. The chest radiography was normal, and the abdominal ultrasound showed abdominal bloating. The upper digestive endoscopy revealed friable esophageal mucosa, with multiple ulceration on the entire esophagus, and whitish exudates especially on the middle and lower part of the esophagus suggesting a possible eosinophilic esophagitis or caused by Candida. Despite the empirical initiated treatment, the patient's evolution was only slowly favorable. The histological exam established the diagnosis of HE.. We initiated acyclovir therapy with an outstandingly favorable evolution.. After 1 month, we detected the seroconversion of IgG anti-HSV. The patient's follow-up revealed no additional complaints.. Despite its rarity in immunocompetent individuals, HE must be taken into account even in otherwise healthy small children. Allergic conditions might represent a predisposing factor for HE.

Myelitis: A Rare Presentation of Epstein Barr Virus.
EBV associated nervous system complications includes encephalitis, meningitis, cerebellitis, polyradiculomyelitis, transverse myelitis, cranial and peripheral neuropathies, and psychiatric abnormalities are usually more commonly seen in immunocompromised patients and rarely in immunocompetent patients. Here we are reporting a 13 years old boy developed headache, malaise, sore throat and low back pain with radiation to both lower limbs. Next day he felt numbness below umbilicus followed by acute onset weakness in both lower limbs and urinary retention. Motor exam revealed proximal muscle power MRC grade 4/5 and distal power 1/5 in right lower limb and proximal power 4-/5 and distal power 0/5 in left lower limb with normal power in both upper limbs. Deep tendon reflexes were bilaterally normal except absent ankle reflexes. Both plantars were mute. All the modalities of sensation including pain, touch, temperature, joint position and vibration were impaired below umbilicus. Routine investigations were normal. The magnetic resonance imaging (MRI) of thoracic spine showed intramedullary lesion in conus, which was iso-hyperintense on T1-weighted and hyperintense on T2- weighted images extending from D12thoracic vertebral level to L1 with cord expansion (Figures 1, 2). The MRI features were suggestive of conus myelitis. Cerebrospinal fluid (CSF) analysis revealed increased protein, normal cells, glucose and Chloride. CSF Polymerase chain reaction (PCR) was positive for Epstein Barr virus . The clinical and imaging findings were consistent with the diagnosis of myelitis and responded well to steroid plus acyclovir treatment. The clinicians should be aware of such uncommon etiology of a common disease.

[EBV-ASSOCIATED PNEUMONIA IN PATIENT WITH GRANULOMATOSIS WITH POLYANGIITIS (GPA) IN IMMUNOSOPPRESSIVE THERAPY TREATED WITH ACICLOVIR].
Granulomatosis polyangiitis (GPA) is an ANCA-related vasculitis (AAV) whose clinical manifestations mainly concern the respiratory tract (upper and lower) and the kidney. The treatment of GPA (as well as other AAV) includes the use of immunosuppressive drugs with numerous side effects; the most frequent complications are infectious and neoplastic. GPA frequently relapses. Epstein Barr Virus (EBV) is a ubiquitous virus; it is estimated that about 90% of the world’s population has BEEN EXPOSED TO with this pathogen and has subsequently developed a latent infection. Under certain conditions including immunosuppression EBV may reactivate. We report the clinical case of a 67-year-old woman who presented with GPA involving the upper respiratory tract and renal failure with the need for hemodialysis treatment. The fourth month of induction therapy with cyclophosphamide and methylprednisone she presented with dyspnea and respiratory failure. After excluding pulmonary embolism and heart failure, a series of investigations including high resolution tomography and fibroscopy with broncoalveolar lavage (BAL) were performed which excluded recurrence of pulmonary vasculitis including alveolar haemorrhage A BAL demonstrated EBV-DNA. On this basis EBV pneumonia was diagnosed, and antiviral therapy with acyclovir was begun, followed by clinical and radiological improvement. In patients with GPA treated with immunosuppressive drugs pulmonary involvement may not only be due to the underlying vasculitis, but also to opportunistic agents, which must always be considered.

Epstein-Barr virus hemorrhagic meningoencephalitis: case report and review of the literature.
Neurologic complications related to Epstein-Barr virus (EBV) in immunocompetent adults are rare and most commonly self-limited. However, severe cases have been previously reported in the literature. We describe a case of meningoencephalitis with frontal bilateral hemorrhage in a non-immunocompromised adult following an EBV infection of the central nervous system confirmed by the presence of EBV-DNA in the cerebrospinal fluid. During the patient's hospital stay, there was a favorable clinical and radiologic evolution and the patient was discharged asymptomatic. To our knowledge, this is the fourth case of hemorrhagic meningoencephalitis related to EBV and the first one in an immunocompetent patient with a favorable outcome.

Post-transplantation Infections in Bolivia.
Over 26 years, we found 46 infectious episodes in 350 kidney transplant recipients. Fifteen were urinary tract infections, recurrent in 4 patients. There were 8 cytomegalovirus infections, three of them fatal when intravenous (IV) ganciclovir was not available. Seven patients had a reactivation of tuberculosis (TB) in the pleura, cervical spine, lumbar spine, knee, ankle, skin and peritoneum, respectively, and were all resolved satisfactorily with conventional anti-TB therapy. Three patients transplanted before routine prophylaxis with the use of acyclovir developed an extensive herpes zoster infection in the 1st 6 months after transplantation, which was resolved with the use of oral acyclovir, and 1 had a disseminated herpes simplex infection resolved with the use of IV acyclovir. Three patients transplanted before routine prophylaxis with trimethoprim sulfa developed Pneumocystis carinii pneumonia in the 1st 6 months after transplantation, which was fatal in one of them. In 2 patients, we found a Nocardia infection, confined to the lung, which was cured in one of the cases and systemic and fatal in the other. Two patients transplanted before routine prophylaxis with the use of nystatin developed esophageal candidiasis in the 1st 6 months after transplantation. One patient developed infective endocarditis in a stenotic bicuspid aortic valve and died 10 years later after another incident of infective endocarditis at the prosthetic aortic valve. Two patients developed an extensive condyloma at the penis, perianal region, and perineum owing to human papillomavirus, requiring extensive surgical resection and podophyllin applications. Another patient developed fatal post-transplantation lymphoproliferative disease due to Epstein-Barr virus infection 15 years after transplantation. One patient developed a severe and fatal mucocutaneous leishmaniasis with no response to conventional antimonial therapy. It is interesting to note that despite Chagas disease being endemic in Bolivia, we had no patients with reactivation or transmission through the graft even though many of the patients and donors were serologically positive for Chagas disease.

Brincidofovir clearance of acyclovir-resistant herpes simplex virus-1 and adenovirus infection after stem cell transplantation.
Infections with adenovirus (AdV) and herpesviruses can result in considerable morbidity and mortality in pediatric hematopoietic stem cell transplant (SCT) recipients. Herpes simplex virus (HSV) reactivations are usually prevented by acyclovir (ACV) prophylaxis, whereas cidofovir (CDV) has been used off indication to manage AdV infections. We report a child with myelodysplastic syndrome undergoing multiple SCT, who experienced HSV-1 disease including severe mucositis and herpetic whitlow, as well as high viral load AdV DNAemia. Both ACV and CDV were ineffective; however, viral loads were decreased with brincidofovir, resulting in viral clearance. A subsequent Epstein-Barr virus disease with relevant meningoencephalitis responded to rituximab.

[A Case of Acute Acalculous Cholecystitis During Infectious Mononucleosis Caused by the Epstein-Barr Virus in a Young Woman].
Infection with the Epstein-Barr virus (EBV) is a common disease and is mainly asymptomatic during childhood, whereas infectious mononucleosis with clinical signs such as fever, pharyngitis, lymphadenopathy and hepatosplenomegaly often occurs in adolescents and adults with primary infection. Acalculous cholecystitis has been reported as a rare complication. We report herein a case of acalculous cholecystitis accompanied by infectious mononucleosis by EBV, which was treated successfully by medical treatment. A 33-year-old woman who had been admitted by fever, pharyngitis and lymphadenopathy developed a right upper quadrant pain, that was diagnosed as acalculous cholecystitis based on an imaging study. Antibiotic treatment did not resolve the symptoms, and surgical intervention was considered. We diagnosed her as having infectious mononucleosis based on a typical physical presentation and seropositivity for the EBV viral capsid antigen, suggesting that the acalculous cholecystatis might have been a complication of the EBV infection. After the administration of glucocorticoid and acyclovir, the patient became afebrile and the abdominal pain disappeared. Though acalculous cholecystitis rarely accompanies infectious mononucleosis caused by EBV, clinicians should be aware of this complication to avoid unnecessary cholecystectomy.

Acute retinal necrosis associated with Epstein-Barr virus: immunohistopathologic confirmation.
Acute retinal necrosis (ARN) is an infectious retinitis primarily caused by the herpesviruses. Although the Epstein-Barr virus (EBV) has been implicated as a cause of ARN, to our knowledge, there has been no histopathologic documentation. We report the clinical history and histopathologic confirmation that EBV can cause ARN.. Clinical course and histopathology of a patient diagnosed with ARN caused by infection with EBV confirmed by molecular pathology.. Epstein-Barr virus is a recognized cause of intraocular inflammation and has been implicated as a possible cause of ARN. However, to our knowledge, tissue demonstration of EBV in a patient with ARN has not previously been reported. We identified the organism in the necrotic retina of a patient receiving immunosuppression because of idiopathic pulmonary fibrosis.

Antiviral treatment of a boy with EBV-associated hydroa vacciniforme.
Hydroa vacciniforme is one of the rarest forms of photosensitivity disorders of the skin. Effective treatment options are scarce and mainly constitute of strict sun protection. Lately, hydroa vacciniforme has been associated with Epstein-Barr virus infection. We present a patient with hydroa vacciniforme and concomitant previous/chronic Epstein-Barr virus infection. In this case, antiviral treatment was successful.

Epstein-Barr virus-associated cerebellar ataxia.
Cerebellar ataxia is a common neurological presentation. It can be acute, subacute or chronic. Neurological complications of Epstein-Barr virus (EBV) are well-recognised with a variety of presentations. Acute cerebellar ataxia is a rare, but an established complication. It has been described as the sole manifestation of EBV infection without the systemic features of infectious mononucleosis. The pathophysiology is not clear. The course of the illness may last for a few months with a benign outcome, though serious complications can happen. We present a case of a 38-year-old man who presented with an acute cerebellar ataxia owing to EBV infection, along with a review of the literature.

Successful outcome of Epstein-Barr virus encephalitis managed with bilateral craniectomy, corticosteroids and aciclovir.
We present a 19-year-old woman with severe encephalitis and raised intracranial pressure requiring decompressive craniectomy. Her clinical features were consistent with encephalitis in the context of acute primary Epstein-Barr virus (EBV) infection (infectious mononucleosis). Serology, bone marrow aspirate and PCR of blood and cerebrospinal fluid confirmed the diagnosis. She was treated with corticosteroids and aciclovir. She was critically unwell for 3 weeks, requiring artificial ventilation but eventually made a good recovery. EBV encephalitis is uncommon, making the diagnosis and decisions about clinical management challenging.

Eye findings in X-linked lymphoproliferative disorder.
X-linked lymphoproliferative disorder typically presents as an Epstein-Barr virus-specific immune defect with a poor prognosis. Herein we present the clinical and pathologic findings for the first known case of X-linked lymphoproliferative disorder with visual symptoms at initial presentation.. Retrospective chart review, clinicopathologic correlation (brain biopsy and postmortem brain and eye tissue), and literature review.. An 18-year-old boy had a unique presentation of X-linked lymphoproliferative disorder with visual symptoms and retinal findings. He subsequently developed central nervous system vasculitis. He never had evidence of Epstein-Barr virus infection during his clinical course, but in situ hybridization was positive in scattered cells in the brain postmortem. Eye pathologic examination at autopsy showed ischemic changes, but no inflammation.. When a young patient presents with cotton wool spots, a thorough workup must be done, and immunologic disorders should be considered in the differential diagnosis. X-linked lymphoproliferative disorder-associated eye findings may not always be associated with Epstein-Barr virus infection and, as demonstrated by this case, can be indicative of an underlying vasculitic process.

Necrotic adenoids in post-transplant lymphoproliferative disorders.
Post-transplant lymphoproliferative disorders (PTLD) are a potentially fatal complication after solid organ transplantation. The majority of cases are associated with Epstein Barr virus infection (EBV). The first manifestations of PTLD are frequently observed in the ENT area with adenoidal and/or tonsillar enlargement.. We present the case of a 12-year old girl with a total nasal obstruction and tonsillitis five months after a kidney transplantation for bilateral congenital kidney hypoplasia.. The EBV genome was detected by polymerase reaction three months after surgery. Fiberoptic examination revealed an obstructive necrotic mass in the naso-pharynx. The anatomic-pathologic analysis revealed necrotic adenoids.. Necrotic tonsillitis is common. Necrosis of the adenoids, although rarer, can also occur and explains the important respiratory distress. Since two thirds of PTLD patients present with clinical symptoms in the ENT area, the otorhinolaryngologist should be aware of this complication.

[Monitoring of early Epstein-Barr virus reactivation and preemptive therapy after allogeneic hematopoietic stem cell transplantation].
To investigate early Epstein-Barr virus (EBV) reactivation and the outcome of preemptive therapy after allogeneic hematopoietic stem cell transplantation (allo-HSCT).. From January 2007 to January 2009, totally 277 patients after allo-HSCT were studied (haploidentical 116, unrelated 75, matched sibling 86). Conditioning regimens were mainly busulfan (BU) + cyclophosphamide (CY)/fludarabine (Flu) or total body irradiation (TBI) + CY/Flu. Antihuman thymocyte globulin (ATG) was added in haploidentical and unrelated transplants. Plasma EBV DNA was monitored once to twice weekly in the first 3 months after allo-HSCT with real time quantitative polymerase chain reaction (RQ-PCR). EBV viremia was diagnosed when EBV DNA was more than 5 × 10(2) copies/ml but without symptoms. Acyclovir (10 mg/kg, intravenous drip, 8 h) was used for preemptive therapy and immuno-suppressants were decreased if possible.. Totally 33 patients (11.9%) developed EBV viremia with a median time at day 44 (day 19 to day 84). The incidences of EBV viremia in the transplants from matched sibling, haploidentical, unrelated donors were 0, 15.5%, 20.0%, respectively. There was no significant difference between haploidentical and unrelated transplants (P = 0.09), but much less EBV viremia was seen in matched sibling transplant (P = 0.001). Twenty of 33 patients (60.6%) had complete response to preemptive therapy. The median time to reach EBV DNA negative in plasma was 11 (4 - 56) d. The median duration of preemptive therapy was 21 (14 - 60) d. Both univariate and multivariate analysis indicated that haploidentical and unrelated transplants, acute graft versus host disease (GVHD) were the risk factors for EBV viremia. Two-year overall survival in the patients with EBV viremia was significantly lower than that without EBV viremia (54.2% vs 72.1%, P = 0.006).. Our large clinical study has demonstrated that preemptive therapy with acyclovir that is guided by EBV viremia is effective in majority of the patients with high-risk for EBV reactivation after allo-HSCT, which may further decrease the risk for developing life-threatening EBV disease or post-transplantation lymphoproliferative disorder. Haploidentical and unrelated transplants, acute GVHD are the risk factors for EBV viremia which has negative impact on survival.

Epstein-Barr virus-related lymphoproliferative disorder, cytomegalovirus reactivation, and varicella zoster virus encephalitis during treatment of medulloblastoma.
The case of a 14-year-old girl who developed Epstein-Barr virus-related lymphoproliferative disorder, cytomegalovirus reactivation, and Varicella zoster virus encephalitis during treatment for medulloblastoma is described. The patient was diagnosed with a cerebral medulloblastoma and treated with systemic chemotherapy, intrathecal chemotherapy, and radiotherapy. Six months later, she developed persistent low-grade fever, abdominal pain, and vomiting. Several mucosal or ulcerated lesions of the stomach and colon were found on fiberscopy. The infiltrating cells were positive for CD20 and EBER1, and the diagnosis of lymphoproliferative disorder was made. CMV antigen was found in the peripheral lymphocytes at that time. At the same time, it was noted that the patient's language was inappropriate for her age, and a facial and abdominal rash, as well as a right facial palsy, had developed. She was then diagnosed as having VZV encephalitis, because VZV was detected in the CSF. She was treated subsequently with acyclovir and oral steroid, and the VZV encephalitis resolved. The lymphoproliferative disorder improved gradually with rituximab, ganciclovir, and total nutritional support. At the time of the development of the lymphoproliferative disorder and VZV encephalitis, the patient had severe lymphopenia and this may have caused these rare phenomena in a non-transplant setting.

CD8(+) T-cell lymphoproliferative disorder associated with Epstein-Barr virus in a patient with rheumatoid arthritis during methotrexate therapy.
A 75-year-old woman with rheumatoid arthritis (RA) who was receiving methotrexate (MTX) therapy developed Epstein-Barr virus (EBV)-associated CD8(+) T-cell lymphoproliferative disorder (LPD) and meningoencephalitis. She was successfully treated with acyclovir and corticosteroids plus MTX cessation. T-cell LPD is relatively rare in RA patients receiving MTX. To our knowledge, this is the first report of CD8(+) T-cell LPD with EBV genome occurring during MTX therapy for RA. EBV infection should be carefully monitored to assess severe EBV-associated complications.

Hemorrhagic leukoencephalitis linked to Epstein-Barr virus in an adult patient.
We report a case of an adult patient who presented a febrile coma linked to Epstein-Barr virus (EBV) encephalitis. EBV polymerase chain reaction (PCR) was positive in cerebrospinal fluid (CSF) and blood serology and PCR in blood was consistent with an EBV reactivation. First cerebral magnetic resonance imaging (MRI) at day 1 was normal but a second MRI at day 13 showed anomaly compatible with a hemorrhagic leukoencephalitis. Treatment consists of intravenous corticotherapy and aciclovir during 21 days. Evolution was favourable with complete neurologic recuperation and no intercurrent lymphoma or vasculitis in 6 months follow-up.

Simultaneous determination of acyclovir, ganciclovir, and (R)-9-[4-hydroxy-2-(hydroxymethyl)butyl]guanine in human plasma using high-performance liquid chromatography.
Acyclovir, ganciclovir and (R)-9-[4-hydroxy-2-(hydroxymethyl)butyl]guanine are active in vitro against the Epstein-Barr virus (EBV) but their in vivo anti-EBV activity is not well understood. We developed a novel, sensitive high-performance liquid chromatography assay with ultraviolet detection for measuring acyclovir, ganciclovir and (R)-9-[4-hydroxy-2-(hydroxymethyl)butyl]guanine in human plasma to identify quantitative relationships between in vitro anti-EBV activity and therapeutic response. Characteristics of the assay include a low plasma volume (200 microL), perchloric acid protein precipitation, use of penciclovir as the internal standard, run times less than 8 min and a 50 ng/mL lower limit of quantification. The within- and between-assay variability is 0.7-4.8 and 1.0-7.9%, respectively. Accuracy for all three drugs ranges from 89.5 to 106.4% for four quality controls (50, 100, 1000 and 10,000 ng/mL). This assay supports pharmacokinetic and pharmacodynamic studies of candidate anti-EBV drugs in children and adults with EBV infections.

Post-transplant EBV-related lymphoproliferative disorder complicating umbilical cord blood transplantation in patients of adrenoleukodystrophy.
EBV-associated post-transplant lymphoproliferative disorder (PTLD) is a well-recognized complication following solid organ transplantation and hematopoietic stem cell transplantation (HSCT) using bone marrow or peripheral blood as stem cell sources, but rarely reported in umbilical cord blood transplantation (UCBT). We report two cases in unrelated UCBT setting and added the following new information to the literature: (i) EBV-related PTLD can be presented late in recipients of unrelated UCBT; (ii) in contrast to reported literatures that PTLD is a serious complication with unfavorable outcome, especially in monomorphic form, our cases showed that the clinical course may be relatively benign if treatment is initiated promptly.

Acute retinal necrosis: clinical features, early vitrectomy, and outcomes.
To determine the viral diagnosis and the outcome of eyes with acute retinal necrosis (ARN) treated with intravenous acyclovir and oral prednisolone alone or combined with early vitrectomy and intravitreal acyclovir lavage.. Nonrandomized, retrospective, interventional, comparative, consecutive series.. A cohort of 27 human immunodeficiency virus-negative patients with ARN comprising 24 unilateral and 3 bilateral cases.. Vitreous biopsy for viral diagnosis. Twenty eyes were treated with intravenous acyclovir in combination with oral prednisolone (group A). Ten eyes were treated additionally with early vitrectomy, intravitreal acyclovir lavage, laser demarcation of necrotic retinal areas when feasible-with or without scleral buckling, and gas or silicone oil tamponade (group B). Vitrectomy was performed in all cases of secondary rhegmatogenous retinal detachment (RD).. Results of vitreous biopsy, rate of RD, rate of phthisis bulbi, and course of best-corrected visual acuity (BCVA).. Varicella zoster virus (VZV) was detected in 26 eyes, followed by herpes simplex virus (5 eyes), and Epstein-Barr virus (2 eyes, in conjunction with VZV). An RD developed in more eyes in group A (18 of 20 eyes) than in group B (4 of 10 eyes; P = 0.007). In 2 of 20 eyes in group A and in 0 of 10 eyes in group B, phthisis bulbi developed without a significant difference between groups A and B. Mean BCVA (logarithm of the minimum angle of resolution) at first visit was 1.09 (standard deviation [SD], 0.83), and mean final BCVA was 1.46 (SD, 0.88) without significant difference between groups A and B.. Varicella zoster virus is the leading cause of ARN. Visual prognosis is guarded. Early vitrectomy with intravitreal acyclovir lavage was associated with a lower incidence of secondary RD; however, it did not improve mean final visual acuity.

Antiviral therapy in children with hydroa vacciniforme.
Hydroa vacciniforme is a rare, usually quite severe, photo-dermatosis. Association with Epstein-Barr virus infection and a possibly increased risk of lymphoproliferative malignancy have been demonstrated. We describe here four patients with Epstein-Barr virus-associated hydroa vacciniforme treated with acyclovir/valacyclovir therapy with a good clinical response. The children were reported to have less fatigue, fewer eruptions, less scarring, and increased ability to spend time outdoors without provoking new eruptions. This was also in agreement with clinical observations. However, one patient progressed into an anaplastic lymphoma kinase-1-negative anaplastic large-cell lymphoma in the upper jaw. This was preceded by an increase in EBV viral load. Acyclovir/valacyclovir therapy is a safe treatment. Further studies are required to confirm these results.

The role of valacyclovir on Epstein-Barr virus viral loads in pediatric liver transplantation patients.
Epstein-Barr virus (EBV) infection occurring in the postoperative period represents a significant risk for pediatric transplant recipients. It presents in various manners, including a mononucleosis-like syndrome, hepatitis, encephalopathy, or posttransplant lymphoproliferative disease (PTLD). Valacyclovir has in vitro activity against EBV. We sought to review our experience with valacyclovir on peripheral blood EBV viral loads among a group of EBV-infected patients after liver transplantation (OLT).. Twelve children of ages 6-36 months (median, 12 months), underwent OLT. Eight (66%) were EBV immunoglobulin (Ig)G seronegative at the time of the operation. Eight patients developed primary infection and 4 patients developed reactivation of a post primary infection. Valacyclovir was prescribed immediately to 3 patients when we detected an acute-primary EBV infection. Valacyclovir was prescribed for 2 patients who had primary EBV infections followed by PTLD. Three patients who had primary EBV infection were administered valacyclovir after they became chronically EBV PCR positive for more than 1 year. Four out of 12 cases (33%) were EBV seropositive at the time of OLT, and underwent postprimary EBV reactivation displaying chronic EBV carrier state for 8-10 months before valacyclovir treatment. Peripheral blood EBV viral loads were tested every 2 months. The primary outcome was the proportion of subjects with EBV viremia who had a >or=2 log 10 decrease in EBV copies/mL after valacyclovir treatment. The duration of valacyclovir treatment was a median of 10 months (range, 8-11 months). At the beginning of the treatment period the median level of EBV viral load was 1.1 x 10(4) (range, 1 x 10(4) to 1 x 10(7)). EBV virus was cleared in only 1 patient with primary acute EBV infection. EBV viral loads did not change in 7 of 12 patients and decreased only 1 log 10 (n = 2) or 2 log 10 (n = 2).. In this small, non-placebo-controlled study, valacyclovir treatment was not effective to decrease peripheral blood EBV viral loads.

EBV reactivation and post transplant lymphoproliferative disorders following allogeneic SCT.
Fatal problems encountered in allogeneic stem cell transplantation include EBV reactivation and post transplant lymphoproliferative disorders (PTLDs) with high mortality rates. We performed a retrospective analysis in all consecutive adult and pediatric EBV reactivations and PTLD during a period of 8.5 years. There were 26 patients with EBV reactivation/PTLD out of a total of 854 transplantations giving an overall incidence of 3.0%. Specifically, the incidence of EBV-PTLD was 1.3%, whereas that of EBV reactivation was 1.8%. Median age was 46.0 and 11.0 years in the adult and pediatric patients, respectively. There were high rates (54%) of concomitant bacterial, viral, fungal and parasitic infections at the time of EBV manifestation. Variable treatment regimens were applied including in most cases an anti-CD20 regimen often in combination with virustatic compounds, polychemotherapy or donor lymphocytes. The mortality rates were 9 of 11 (82%) in patients with EBV-PTLD and 10 of 15 (67%) in patients with reactivation. Only 7 of 26 patients (27%) are alive after a median follow-up of 758 days (range 24-2751). The high mortality rates of EBV reactivation and of EBV-PTLD irrespective of multimodal treatment approaches emphasize standardization and optimization of post transplant surveillance and treatment strategies to improve control of these often fatal complications.

Epstein-Barr virus encephalitis mimicking clinical and electroencephalographic characteristics of herpes simplex encephalitis.
A rare case of EBV encephalitis initially diagnosed as Herpes simplex infection is presented to highlight the importance of EBV specific intrathecal ELISA and liquor PCR based differential diagnosis when Herpes simplex encephalitis specific clinical symptoms, neuroimaging signs and electroencephalographic features are present. The case report also suggests that acyclovir treatment might be beneficial for the long term outcome in adult EBV encephalitis patients.

[Epstein-Barr virus infection as etiological and pathogenetic factor of exudative otitis media in childhood].
A detailed examination of 40 children with recurrent exudative otitis media (EOM) using enzyme immunoassay and polymerase chain reaction suggested that ENT pathology in the above children (EOM, adenoiditis, tonsillopharyngitis, sinusitis) may be a complication of acute or chronic Epstein-Barr virus infection (EBVI) because primary EBVI infection or its long-term persistence followed secondary immunodeficiency resulting in lymphoid system impairment and damage of upper airway epithelium. This causes a recurrent and persistent course of EOM. Etiotropic and pathogenetically sound treatment of children with recurrent EOM includes antiviral therapy, immunocorrection, rehabilitation with participation of pediatrician, immunologist, infection therapist.

9-(2-C-Cyano-2-deoxy-beta-D-arabino-pentofuranosyl)guanine, a potential antitumor agent against B-lymphoma infected with Kaposi's sarcoma-associated herpesvirus.
Several 9-(2-C-cyano-2-deoxy-l-beta-d-arabino-pentofuranosyl)purine derivatives were tested against Kaposi's sarcoma-associated herpesvirus (KSHV)-infected primary effusion lymphoma (PEL) cells. The guanine derivative (3, CNDAG), as well as the 2-amino-6-substituted-purine derivatives 4, 5, and 6, exhibited cell growth inhibitory activity against KSHV-infected cells, but showed no cytotoxicity against KSHV-negative cells at >15 microM concentrations. Therefore, it was found that compounds 3, 4, 5, and 6 showed selective cytotoxicity against PEL cells infected with KSHV.

Acute retinal necrosis features, management, and outcomes.
To determine the viral diagnosis and factors affecting the visual outcome of eyes with acute retinal necrosis.. Nonrandomized, retrospective, interventional, noncomparative series.. A cohort of 22 human immunodeficiency virus-negative patients with acute retinal necrosis (ARN). There were 17 unilateral and 5 bilateral cases.. Diagnostic vitreous biopsy for polymerase chain reaction (PCR) viral DNA analysis, prophylactic barrier laser posterior to necrotic retina to try to prevent rhegmatogenous retinal detachment (RD), intravenous acyclovir in combination with oral, and vitrectomy for RD repair.. Results of PCR viral DNA analysis, relationship between prophylactic barrier argon laser photocoagulation and occurrence of RD, and visual acuities at presentation and follow-up.. Varicella-zoster virus (VZV) was detected in 66.7% (12/18) of eyes (66.7% of patients [10/15]) with vitreous biopsy and herpes simplex virus (HSV) in 22.2% (4/18) of eyes (20% of patients [3/15]). Epstein-Barr virus (EBV) was detected in 16.7% (3/18) of eyes (20% of patients [3/15]), and all the EBV-positive eyes were also positive for VZV. Polymerase chain reaction results were identical in both eyes of bilateral cases (5 patients) and were negative in 11.1% (2/18) of eyes (13.3% of patients [2/15]) biopsied. Systemic corticosteroid treatment given before ARN diagnosis did not appear to increase the risk of developing RD (P = 0.69). Rhegmatogenous RD occurred in 35.3% (6/17) of eyes given prophylactic argon laser treatment and in 80% (8/10) of eyes that could not be lasered prohylactically. Of RDs, 96.3% (13/14) occurred after the third week and up to 5 months from onset of symptoms. The VA after surgical repair of RD improved relative to the presentation acuity in 33.3% (4/12) of eyes.. Varicella-zoster virus is the leading cause of ARN. We recommend the management of ARN to include prompt diagnosis; prophylactic argon laser retinopexy, preferably within the first 2 weeks to reduce risk of RD; systemic acyclovir; and corticosteroids to control the severe inflammation associated with ARN. Despite the guarded visual prognosis, RD repair may result in improved visual outcomes.

[Acute respiratory distress syndrome complicating Ebstein-Barr virus pneumonia].
In the immuno-competent adult Ebstein-Barr virus (EBV) infection is a self-limiting disease that resolves spontaneously.. We report a case of acute respiratory distress syndrome (ARDS) complicating severe EBV pneumonia and requiring prolonged artificial ventilation. The diagnosis was confirmed by specific serology and estimation of the viral load by PCR. Apart from supportive treatment with artificial ventilation the medical treatment included the use of Acyclovir and polyclonal immunoglobulins in the early phase and corticosteroids in the late phase. Recovery was progressive and complete.. ARDS can complicate EBV pneumonia in an immuno-competent subject. Its management represents a diagnostic and therapeutic challenge.

[Description of a peculiar form of Hodgkin's disease associated with Epstein-Barr virus infection].
The authors report a peculiar form of Hodgkin's disease that is associated with Epstein-Barr virus infection. A 16-year-old patient was admitted for an autoimmune haemolytic anaemia associated with IgG auto-immune antibodies, linked to general clinical complications, cervical adenopathies and splenomegalia. The patient underwent hemicavectomy that was not histologically investigated. The ganglionar exeresis helped to establish the histological diagnosis of Hodgkin's disease, classic form with nodular sclerosis. Tumour cells were CD30 CD15 positive and neighbouring lymphoid cells were CD3 and CD20 positive. In situ hybridation allowed the detection of Epstein-Barr virus in tumour cells. Under ABVD chemotherapy supplemented with acyclovir and initial corticotherapy, mid-treatment evolution appears to be favourable. This observation is consistent with the hypothesis that tumour cells are of B cell origin during Hodgkin's disease, together with the involvement of Epstein-Barr virus in lymphomagenesis.

Late-onset fatal Epstein-Barr virus-associated hemophagocytic syndrome following cord blood cell transplantation for adult acute lymphoblastic leukemia.
A 43-year-old Japanese woman underwent unrelated cord blood transplantation (CBT) during remission for acute lymphoblastic leukemia with t(4; 11)(q21;q23). Tacrolimus was given for prophylaxis of graft-versus-host disease. The posttransplantation clinical course was mostly uneventful, and the leukemia remained in remission. Fourteen months after CBT, the patient developed pancytopenia and hepatic dysfunction with persistent high-grade fever. The bone marrow was hypocellular with increased numbers of macrophages and hemophagocytes. The numbers of Epstein-Barr virus (EBV) copies in peripheral blood samples were remarkably high. Although the patient showed complete donor-type hematopoiesis, the titer of viral capsid antigen immunoglobulin G was low, and the results of a test for EBV nuclear antigen were negative. There was no clinical response to the reduction of immunosuppressive therapy or to the administration of high-dose methylprednisolone, human immunoglobulin, or acyclovir. The patient died 466 days after CBT of massive gastrointestinal hemorrhage due to bone marrow and hepatic failures. This case demonstrates that fatal EBV-associated hemophagocytic syndrome (HPS) can occur more than 1 year after CBT. This report is the first of a case of late-onset EBV-associated HPS following CBT.

Full clinical recovery after topical acyclovir treatment of Epstein-Barr virus associated cutaneous B-cell lymphoma in patient with mycosis fungoides.
Primary cutaneous T- and B-cell lymphomas are a heterogeneous group of diseases with varied clinical presentations and prognosis. The use of new molecular, histological, and clinical criteria has improved their recognition. Cutaneous B-cell and T-cell lymphomas are seldom found together in the same patient. Here we report a rare case of mycosis fungoides variant of a cutaneous T-cell lymphoma (CTCL) which later developed Epstein-Barr virus (EBV) associated cutaneous B-cell lymphoproliferative disorder. The patient initially presented with generalized erythroderma, extensive plaques, and axillary lymphadenopathy. Histopathology and immunophenotyping of her tumor from the right breast nodule revealed a T-cell lymphoma consistent with mycosis fungoides. She was initially treated with pentostatin, followed by topical mechlorethamine and topical steroids. After progression of her mycosis fungoides with worsening diffuse skin lesions on this regimen, her treatments were changed to oral bexarotene with an initial partial response followed by stable disease. Three years from her initial presentation, she developed ulcerated cauliflower-like nodules on her forehead. Biopsy of these lesions revealed EBV-positive large- and medium-sized pleomorphic B-cells consistent with EBV-driven B-cell lymphoproliferative disorder. She was treated with topical acyclovir cream on the involved skin areas while continuing with oral bexarotene for mycosis fungoides. Skin lesions gradually diminished and totally disappeared after four weeks of topical acyclovir treatment. Bexarotene treatment was continued for another year until the mycosis fungoides progressed and became wide spread causing her death four and a half years after the initial diagnosis. The coexistence of two cutaneous non-Hodgkin lymphomas of different lineage in the same patient and the complete clinical response of EBV-related B-cell cutaneous component to topical acyclovir makes this rare case particularly interesting.

Successful management of recurrent Epstein-Barr virus-associated multilocular leiomyosarcoma after cardiac transplantation.
In contrast to Epstein-Barr virus (EBV)-associated posttransplant lymphoproliferative disorders (PTLD), EBV-associated leiomyomatous tumors have thus far only rarely been described.. Two years after heart transplantation with ATG induction, cyclosporine (CsA; trough levels of 250 ng/mL)-based triple drug immunosuppression), a 23-year-old patient developed a small round lesion within the left lateral liver segment. The patient underwent ultrasound-guided biopsy followed by liver resection. Histological and immunohistological examination showed a leiomyosarcoma. In situ hybridization using EBV-specific EB endoplasmic reticulum-RNA showed an intensive signal in almost all tumor cells. The tumor stained for EB nuclear antigen (EBNA)-2-protein. Immunosuppression was drastically reduced, namely, CsA levels <100 ng/dL, prednisolone 5 mg, azathioprine withdrawn, and antiviral chemotherapy initiated with 10 days of IV gancyclovir and acyclovir followed by oral famcyclovir. During the follow-up, anti-EBV-IgM, anti-early antigen antibodies, and anti-EBNA antibodies were continuously monitored excluding significant EBV replication. Eighteen months post-liver resection, and high-resolution computed tomography scan demonstrated two paravertebral tumors. These lesions and a small nodule at the left ankle were resected revealing identical leiomyosarcomata. Immunosuppression was further reduced (CsA levels 75 ng/dL) and famcyclovir maintenance therapy started. Nevertheless, 2 years later the patient again developed tumor recurrence (perirectal, liver, and right adrenal gland); the tumors were surgically removed. The therapy was switched to Rapamycin and famcyclovir was continued. Three years after the last surgical intervention, the patient is well and recurrence-free.. Long-term survival in patients with posttransplant EBV-associated leiomyosarcoma can be achieved by combined surgical intervention, reduction of immunosuppression, switch to Sirolimus, and antiviral chemotherapy.

A case of Epstein-Barr virus infection complicated with Guillain-Barré syndrome involving several cranial nerves.
This report presents a case of infectious mononucleosis with severe neurological complications in a previously healthy young female. Both peripheral and cranial nerves were affected causing paralysis and need for assisted ventilation. There was a clear correlation between the symptoms and the serological findings, indicating that the causative agent was Epstein-Barr virus. The patient was treated with acyclovir, methylprednisolone and immunoglobulins. Two months later she had recovered completely. Epstein-Barr virus infection must be considered among the possible causes in patients with cranial nerve affection or Guillain-Barré syndrome.

[Adoptive transfer of Epstein-Barr virus-specific T-lymphocytes in chronic active Epstein-Barr infection].
A 27-year-old man was admitted because of intermittent fever, fatigue, lymphadenopathy and splenomegaly for 20 years. Chronic administration of 6 - 8 g aspirin per day (self-prescribed) resulted in limited control of symptoms and in the development of analgesic nephropathy.. The patient had prominent splenomegaly and lymphadenopathy without histological signs of malignancy. Monocytosis and T-lymphopenia were also present. Infectious disease testing revealed IgG+/IgM- EBV serology and EA-EBV-mRNA nested PCR clearly demonstrated the presence of lytic EBV-proteins in PBMCs.. As chronic active Epstein-Barr virus infection (CAEBV) was highly probable, treatment with aciclovir, gancilovir and steroids was started. Because treatment failed adoptive T-cell transfer with autologous EBV-specific T-cells was performed. After three consecutive infusions the patient responded with a complete remission of fever, fatigue, lymphadenopathy and splenomegaly without adverse effects. Retrospective real-time PCR analysis showed a decrease in viral load from 62847 copies/ microg DNA to 45 - 250 copies after treatment. The patient remains in stable remission without signs of CAEBV (> 4 years).. Adoptive transfer of autologous, EBV-specific T-lymphocytes is a promising treatment in CAEBV.

Effective anti-viral therapy for hemophagocytic syndrome associated with B-cell lymphoma.
A rheumatoid arthritis (RA) patient treated with low-dose methotrexate (MTX) therapy suffered from hemophagocytic syndrome (HPS) associated with B-cell lymphoma (B-LAHS). Administration of acyclovir and intravenous immunoglobulin promptly resolved laboratory test abnormalities accompanied with HPS. Moreover, hemophagocytic histiocytes and lymphoma cells in the bone marrow disappeared without anti-cancer therapy. Two months after reintroduction of MTX for RA flare, lymphoma re-grew rapidly without bone marrow involvement and HPS. Two cycles of combination chemotherapy induced the lymphoma to a complete remission/unconfirmed (CRu), but then the chemotherapy was discontinued due to severe side effects. In this case, on the basis of RA and MTX induced immunosuppressive state, Epstein-Barr virus (EBV) infection was associated with the development of HPS and lymphoma. Anti-viral therapy alone was effective against HPS and lymphoma at initial presentation and improved her general condition. This case indicates that anti-cancer therapy should be preceded by anti-viral therapy and withdrawal of immunosuppressive therapy in patients under immunosuppressive therapy, as long as the clinical situation permits.

Epstein-Barr virus DNA load in cerebrospinal fluid and plasma of patients with AIDS-related lymphoma.
Detection of Epstein-Barr virus (EBV) DNA in the cerebrospinal fluid (CSF) is associated with acquired immunodeficiency syndrome (AIDS)-related brain lymphoma. Real-time polymerase chain reaction (PCR) was performed to quantify EBV DNA in CSF and plasma from 42 patients with AIDS-related non-Hodgkin's lymphoma (NHL). Twenty patients had primary central nervous system lymphoma (PCNSL) and 22 systemic NHL, including 12 with central nervous system involvement (CNS-NHL). As controls, 16 HIV-infected patients with other CNS disorders were examined. EBV DNA was detected in the CSF from 16/20 (80%) patients with PCNSL, 7/22 (32%) with systemic NHL, 8/12 (67%) with CNS-NHL, and 2/16 (13%) of the controls. The viral EBV DNA levels were significantly higher in the CSF from patients with PCNSL or CNS-NHL compared to patients with systemic NHL or controls. EBV DNA was detected in plasma from 5/16 (31%) patients with PCNSL, 9/16 (56%) with systemic NHL, 4/9 (44%) with CNS-NHL, and 4/15 (27%) controls. No difference in plasma viral load was found between patient groups. From the patients with CNS-NHL, plasma samples drawn prior to CNS involvement contained significantly higher EBV DNA levels than those from systemic NHL patients without subsequent CNS involvement. EBV DNA levels in the CSF, but not in plasma, from patients treated with antiherpes drugs were significantly lower than in untreated patients. High CSF EBV DNA levels were found in HIV-associated brain lymphomas and the viral load can be clinically useful. High plasma EBV DNA levels might predict CNS involvement in systemic NHL.

Posttransplant lymphoproliferative disease in a child: clinical and molecular characterization.
We report a 12-year-old girl suffering from end-stage renal disease due to focal-segmental sclerosis and retardation of statomotoric and mental development of unknown origin. Renal transplantation (TX) was performed 7 months after initiation of peritoneal dialysis at the age of 11 years. Immunosuppressive therapy included cyclosporine A, mycophenolate mofetil and methylprednisolone. The patient developed spiking fever up to 40 degrees C without signs of infection 10 months after TX. Kidney function remained stable but ultrasound examination and CT-scan showed hypodense masses within both liver and spleen. Epstein-Barr virus (EBV) polymerase chain reaction (PCR) results with a high number of copies (20 x 10(6) copies/ml blood) against the background of a previous EBV infection (IgG positive, IgM negative) made the diagnosis of EBV-reactivation likely. Splenectomy was performed. Examination of the spleen showed EBV-associated polymorphic posttransplant lymphoproliferative disease (PTLD) with predominant B cell proliferation and monoclonal VH3-rearrangement of the IgG heavy chain locus. Therapy with acyclovir was introduced and immunosuppression was reduced. No rejection episode occurred. Body temperature normalized and the patient recovered over a 3-month period. EBV-PCR in plasma was negative (0.02 x 10(6) copies/ml blood) 12 weeks after reduction of immunosuppression. The liver masses completely resolved after 27 months. After a total follow-up of 36 months the child remains in good health.

Epstein-Barr virus-associated lymphoma in a child undergoing an autologous stem cell rescue.
Epstein-Barr virus-associated lymphoproliferative disease (EBV-LPD) is a serious disorder seen in various states of immunodeficiency, often with a fatal outcome. In this article, a patient with EBV-lymphoma after autologous stem cell rescue for treatment of a nonhematologic solid tumor is described. The child, a 4-year-old boy, had unilateral retinoblastoma with metastatic spread to the central nervous system. He had previously received both local tumor bed and craniospinal radiation therapy together with intensive myeloablative alkylator chemotherapy before autologous stem cell rescue. Histologically confirmed lymphoma with evidence of active EBV proliferation developed within cervical lymph nodes 3 weeks after his first autologous stem cell rescue. A complete clinical remission of the lymphadenopathy was obtained after infusions of rituximab (an anti-CD20 monoclonal antibody), acyclovir, and high-titer anticytomegalovirus immunoglobulin. The patient died approximately 6 months later of persistent and progressive retinoblastoma without any clinical evidence of lymphoma. It is concluded that EBV-LPD should be included in the differential diagnosis in patients in whom lymphadenopathy develops after autologous stem cell rescue.

Treatment of EBV driven lymphoproliferation with erythrophagocytosis: 12 year follow up.
This is a report of a case of Epstein-Barr virus (EBV) associated haemophagocytic syndrome in a 17 year old woman with antibody deficiency. For two years before this presentation, serology showed abnormally high titres to EBV early antigen, suggestive of persistent infection with EBV. She became acutely unwell with clinical features consistent with virus associated haemophagocytic syndrome (VAHS). Histology showed lymphoproliferation with erythrophagocytosis and evidence of EBV encoded RNAs in liver, spleen, and lymph node. VAHS is often fatal, particularly when it occurs in patients with underlying immunodeficiencies. In this case, treatment with intravenous immunoglobulin, aciclovir, and alpha interferon was followed by a dramatic recovery. Twelve years later the patient remains relatively well on regular intravenous immunoglobulin.

Epstein-Barr virus dacryoadenitis resulting in keratoconjunctivitis sicca in a child.
To describe a case of severe dry eye syndrome in a child.. Observational case report. The authors describe a 10-year-old male with severe dry eyes who was profoundly disabled by pain and photophobia despite aggressive conventional therapy. Lacrimal gland histology was consistent with the primary Sjögren syndrome, and serologic and immunohistologic evidence supported the hypothesis of Epstein-Barr virus causality.. Treatment with systemic acyclovir and cyclosporin A resulted in dramatic and rapid reversal of the profound sicca syndrome and enabled the patient to resume his normal activities.. Epstein-Barr virus dacryoadenitis should be considered in the differential diagnosis of keratoconjunctivitis sicca in children. Epstein-Barr virus can cause keratoconjunctivitis sicca, which can be treated successfully with acyclovir therapy in addition to suppression of the inflammatory response.

Persistent productive Epstein-Barr virus replication in normal epithelial cells in vivo.
Productive Epstein-Barr virus (EBV) replication characterizes hairy leukoplakia, an oral epithelial lesion typically occurring in individuals infected with human immunodeficiency virus (HIV). Serial tongue biopsy specimens were obtained from HIV-infected subjects before, during, and after valacyclovir treatment. EBV replication was detected by Southern hybridization to linear terminal EBV genome fragments, reverse-transcriptase polymerase chain reaction amplification of EBV replicative gene transcripts, immunohistochemical detection of EBV replicative protein, and in situ hybridization to EBV DNA. EBV replication was detected in both hairy leukoplakia and normal tongue tissues. Valacyclovir treatment completely abrogated EBV replication in vivo, resulting in resolution of hairy leukoplakia when it was present. EBV replication returned in normal tongue epithelial cells after valacyclovir treatment. These data suggest that normal oral epithelium supports persistent EBV infection in individuals infected with HIV and that productive EBV replication is necessary but not sufficient for the pathogenesis of oral hairy leukoplakia.

Value of long-term administration of acyclovir and similar agents for protecting against AIDS-related lymphoma: case-control and historical cohort studies.
Acyclovir or similar agents with activity against Epstein-Barr virus (EBV) theoretically may prevent non-Hodgkin's lymphoma (NHL) in AIDS. A case-control study of 29 patients with AIDS-related NHL and 58 matched control subjects assessed the frequency with which daily acyclovir (>/=800 mg/d) or similar agents were used for > or =1 year. In a historical cohort of 304 patients with AIDS for > or =2 years, the prevalence of NHL was assessed among 3 groups of patients: those who received long-term treatment with high-dose acyclovir (or similar agents) or low-dose or intermittent acyclovir; those treated with ganciclovir/foscarnet for <1 year; and those who had not previously been treated with acyclovir, ganciclovir, or foscarnet. In the case-control study, 22 patients (72.4%) with NHL never received acyclovir or similar drugs versus 19 control subjects (32.8%; P=. 002); 2 patients (6.9%) with NHL received acyclovir (> or =800 mg/d) for > or =1 year versus 27 (46.6%) of control subjects (P=.0001). In the cohort study, 6 (6.8%) of 88 patients who received acyclovir (> or =800 mg/d) for > or =1 year developed NHL versus 15 (15.5%) of 97 patients who received intermittent or lower-dose acyclovir and 30 (25.2%) of 119 patients who never received these agents (P=.002). Long-term administration (>1 year) of high-dose acyclovir or similar agents with anti-EBV activity may prevent NHL in patients with AIDS. A prospective, randomized study is warranted to confirm these results.

Prophylaxis against herpes infections in kidney transplant patients with special emphasis on CMV.
Since 1990, we have treated all kidney transplanted patients with cyclosporin (CsA)+ an initial 10 d antilymphocyte globulin (ALG) course, from September 1995 supplemented with mycophenolate mofetil (MMF). In 170 consecutive transplantations from June 1992 to the end of 1996, aciclovir 3200 mg/d (adjusted for kidney function and in children to age) was given prophylactically for 3 months post-transplantation (Tx), monitored with systematic and frequent tests for HSV and CMV. In case of CMV infection, we gave ganciclovir intravenously (oral ganciclovir from 1996) in doses according to kidney function for 3 months, followed by a further 3 months observation and monitoring period. In case of acute cellular rejection, ganciclovir was given during the 10-d OKT3 course and 1 week further. In case of delayed graft function combined with aciclovir side effects, ganciclovir was given until aciclovir could be reintroduced.. 39% were HSV seronegative at Tx. There were no seroconversions or reactivations within the observation period. No mucocutaneous HSV infections was observed. No resistant strains developed. 26% were both HSV and CMV negative at Tx. 52% were CMV negative at Tx. 30% experienced a CMV infection post-transplant. The patients were grouped according to CMV status in the donor (D) and recipient (R) before Tx. We found approximately the same number of patients in the 4 CMV groups D-/R-, D+/R-, D-/R+ and D+/R+. Most infections occurred in the D+/R- group compared to D-/R- (p = 0.009). A significant increase in the number of CMV infections occurred in this subgroup when we gave reduced doses in case of delayed graft function (p = 0.015), from 1994. We observed only 1 CMV disease (in 1992). Serological EBV testing were performed concomitantly. No correlation was seen between CMV and EBV infections. From September 1995 we have treated all transplanted patients (n = 40) with CsA/ALG/MMF. We found no significant increase in CMV infections in this group.. Prophylaxis with aciclovir (combined with ganciclovir during acute rejections and in case of delayed graft function with aciclovir side effects) gives a good protection against HSV and CMV infections and prevents CMV disease effectively. High-dose aciclovir post-transplantation (or shift to ganciclovir) seems to be important to obtain effective prophylaxis. Better immunosuppression with MMF does not result in more CMV infections.
