valganciclovir and Colitis

A follow-up blood count was performed on a 74-year-old woman diagnosed with colitis due to cytomegalovirus and under treatment with valganciclovir. The automated complete blood count revealed an abnormal white blood cells (WBC) scattergram together with WBC alert flags. The peripheral blood smear showed neutrophils with markedly hyposegmented nuclei or bilobed nuclei and very condensed chromatin or clumping chromatin all consistent with Pelger-Huët anomaly (PHA). We checked previous blood counts, ruling out an inherited PHA. We assessed the haematological, infectious and iatrogenic aetiologies for an acquired PHA. Once the valganciclovir treatment was completed and the drug was withdrawn, without changing the rest of the treatment, the morphological abnormalities of neutrophils were completely resolved. We conclude therefore that the acquired PHA presented by our patient is probably related to valganciclovir treatment.

CMV colitis has been reported in immunocompromized patients with severe deficiency of CD4+ T cells and T cell functions. In this study we present an extensive immunological analysis in a patient with primary hypogammaglobulinemia and CMV colitis who had normal numbers of CD3+T, CD4+T and CD8+T cells, and normal T cell proliferative responses to mitogens and recall antigens. Naïve (T

A 54-year-old man presented with a 6-week history of chronic diarrhea and weight loss of 11 kg after returning from a holiday in Thailand. The patient had a 9-year history of an untreated HIV infection. Despite treatment of a culture-proven Shigella enteritis and strongyloidiasis the symptoms persisted. Finally, cytomegalovirus (CMV) colitis was diagnosed by colonoscopy. The patient recovered completely after starting antiretroviral and valganciclovir treatment. An additional opportunistic infection with multiresistant pulmonary tuberculosis was diagnosed.

To report the improvement of diarrhea in a patient with cytomegalovirus (CMV) colitis who was treated with octreotide after failure of loperamide.. An 84-year-old male presented with chronic diarrhea and CMV colitis; he had been experiencing protracted diarrhea since 2006. In October 2009 he failed a 21-day course of valgancyclovir 900 mg orally twice daily. Several months later, due to continuing diarrhea and progressive malnutrition, a colonoscopy and subsequent biopsy again showed CMV. In March 2010 he was started on a 28-day course of intravenous ganciclovir 130 mg daily. Three weeks into treatment he continued with copious amounts of diarrhea, with no relief from loperamide, which was titrated from 2 mg/day to 2 mg every 6 hours. On day 20 of ganciclovir treatment he was started on octreotide 50 μg subcutaneously every 8 hours; within a few days, the patient began to experience decreased stool frequency and consistency. He completed the full 28-day course of ganciclovir, with octreotide continuing unchanged, with much improvement in his diarrheal symptoms and improvement in appetite, nutritional status, and quality of life.. Studies regarding the treatment of CMV colitis-associated diarrhea are scarce, and are typically limited to treating the underlying cause with antiviral medications and with the addition of antimotility agents. Three cases have been reported in the literature in which octreotide was used for the symptomatic treatment of diarrhea, none of which was refractory to loperamide.. This is the first known case of a patient with chronic diarrhea due to CMV colitis that was unresponsive to loperamide, required protracted antiviral treatment (valgancyclovir and gancyclovir), and subsequently experienced relief by the use of octreotide 50 μg subcutaneously every 8 hours.

To describe a case of cytomegalovirus (CMV) viremia and colitis in a patient on mycophenolate mofetil (MMF) monotherapy for birdshot chorioretinopathy.. Case report.. Retrospective chart review.. Treatment with MMF 1.5 g twice daily for 5 years led to leucopenia and a CD4 count of 299, which resulted in active CMV infection.. Treatment with MMF alone may put otherwise immune-competent individuals at risk for opportunistic CMV infection. Greater awareness of this association may allow for better monitoring, earlier detection, and treatment of future cases.

Most cases of cytomegalovirus (CMV) colitis that develop in patients with inflammatory bowel disease (IBD) are caused by reactivation of a latent virus. Primary CMV infections are rare in adult patients. Treatment with immunosuppressive agents increases the infection risk in patients with IBD. We present a 26 year old lady with primary CMV colitis, superimposed on underlying Crohn's colitis. The diagnosis was confirmed by a viral-like prodrome, a positive CMV IgM titer, presence of low avidity IgG antibodies to CMV, high CMV DNA titers in the plasma, and immunohistological detection of CMV positive cells in her colonic mucosa. The patient responded to initial treatment with intravenous ganciclovir with a fall in plasma levels of CMV DNA, treatment was completed with oral valganciclovir until plasma CMV DNA levels became undetectable.
