rifampin and Diarrhea

The most effective way to control severity and mortality rate of the novel coronavirus disease (COVID-19) is through sensitive diagnostic approaches and an appropriate treatment protocol. We aimed to identify the effect of adding corticosteroid and Tocilizumab to a standard treatment protocol in treating COVID-19 patients with chronic disease through hematological and lab biomarkers.. This study was performed retrospectively on 68 COVID-19 patients with chronic disease who were treated by different therapeutic protocols. The patients were categorized into four groups: control group represented the patients' lab results at admission before treatment protocols were applied; group 1 included patients treated with anticoagulants, Hydroxychloroquine, and antibiotics; group 2 comprised patients treated with Dexamethasone; and group 3 included patients treated with Dexamethasone and Tocilizumab.. The study paves the way into the effectiveness of combining Dexamethasone with Tocilizumab in treatment COVID-19 patients with chronic diseases.. La forma más eficaz de controlar la gravedad y la tasa de mortalidad de la enfermedad del nuevo coronavirus (COVID-19) es mediante enfoques de diagnóstico sensibles y un protocolo de tratamiento adecuado. Nuestro objetivo fue identificar el efecto de agregar corticosteroides y tocilizumab a un protocolo de tratamiento estándar en el tratamiento de pacientes con COVID-19 con enfermedad crónica a través de biomarcadores hematológicos y de laboratorio.. Este estudio se realizó de forma retrospectiva en 68 pacientes COVID-19 con enfermedad crónica que fueron tratados por diferentes protocolos terapéuticos. Los pacientes se clasificaron en cuatro grupos: el grupo de control representaba los resultados de laboratorio de los pacientes en el momento de la admisión antes de que se aplicaran los protocolos de tratamiento; el grupo 1 incluyó a pacientes tratados con anticoagulantes, hidroxicloroquina y antibióticos; el grupo 2 estaba compuesto por pacientes tratados con dexametasona; y el grupo 3 incluyó a pacientes tratados con dexametasona y tocilizumab.. El estudio allana el camino hacia la eficacia de la combinación de dexametasona con tocilizumab en el tratamiento de pacientes con COVID-19 con enfermedades crónicas.. The Child-Mother Index constitutes a potential useful risk factor indicator for statistical analyses on data after birth. The value of the Child-Mother Index based on the estimated fetal weight before birth deserves evaluation.. Six ceria supports synthesized by various synthesis methodologies were used to deposit cobalt oxide. The catalysts were thoroughly characterized, and their catalytic activity for complete methane oxidation was studied. The supports synthesized by direct calcination and precipitation with ammonia exhibited the best textural and structural properties as well as the highest degree of oxidation. The remaining supports presented poorer textural properties to be employed as catalytic supports. The cobalt deposited over the first two supports presented a good dispersion at the external surface, which induced a significant redox effect that increased the number of Co. Some studies show that children with obesity are more likely to receive a diagnosis of depression, anxiety, or attention-deficit hyperactivity disorder (ADHD). But this does not necessarily mean obesity causes these conditions. Depression, anxiety, or ADHD could cause obesity. A child's environment, including family income or their parents' mental health, could also affect a child's weight and mental health. Understanding the nature of these relationships could help scientists develop better interventions for both obesity and mental health conditions. Genetic studies may help scientists better understand the role of the environment in these conditions, but it's important to consider both the child's and their parents’ genetics in these analyses. This is because parents and children share not only genes, but also environmental conditions. For example, families that carry genetic variants associated with higher body weight might also have lower incomes, if parents have been affected by biases against heavier people in society and the workplace. Children in these families could have worse mental health because of effects of their parent’s weight, rather than their own weight. Looking at both child and adult genetics can help disentangle these processes. Hughes et al. show that a child's own body mass index, a ratio of weight and height, is not strongly associated with the child’s mental health symptoms. They analysed genetic, weight, and health survey data from about 41,000 8-year-old children and their parents. The results suggest that a child's own BMI does not have a large effect on their anxiety symptoms. There was also no clear evidence that a child's BMI affected their symptoms of depression or ADHD. These results contradict previous studies, which did not account for parental genetics. Hughes et al. suggest that, at least for eight-year-olds, factors linked with adult weight and which differ between families may be more critical to a child's mental health than a child’s own weight. For older children and adolescents, this may not be the case, and the individual’s own weight may be more important. As a result, policies designed to reduce obesity in mid-childhood are unlikely to greatly improve the mental health of children. On the other hand, policies targeting the environmental or societal factors contributing to higher body weights, bias against people with higher weights, and poor child mental health directly may be more beneficial..

Clostridium difficile disease is the major, known cause of nosocomial diarrhea and is an emerging cause of community-associated diarrhea. Recent outbreaks due to a strain of apparent increased virulence, BI/NAP1, and recognition of increasing metronidazole treatment failures as well as the morbidity associated with recurrent C. difficile disease have begun to spur studies to develop new therapies for C. difficile disease. Nitazoxanide, tolevamer, ramoplanin, and rifaximin are key agents being evaluated as new therapies for C. difficile disease. For now, vancomycin or metronidazole combined with discontinuation of antibiotics, when feasible, and expert infection control remain the mainstays of C. difficile disease management.

Rifaximin is a rifamycin analogue with a broad spectrum of activity similar to that of rifampin; however, because it is poorly absorbed in the gastrointestinal tract, the focus of its development has been on intestinal infections and diseases. This agent has proven to be as effective as ciprofloxacin in treating travelers' diarrhea due to Escherichia coli, although it is ineffective in treating infections due to Campylobacter jejuni. Other potential uses for rifaximin in gastroenterologic disorders include treatment of hepatic encephalopathy, intestinal gas and gas-related symptoms, diverticular disease, intestinal bacterial overgrowth, pouchitis, ulcerative colitis, and active Crohn's disease. This article highlights several studies demonstrating the efficacy of rifaximin in treating travelers' diarrhea as well as other gastrointestinal diseases and discusses the drug's pharmacokinetics, indications, contraindications, warnings, precautions, adverse reactions, and dosing.

Rifampin therapy is an infrequently reported cause of pseudomembranous colitis. A low index of suspicion may account for this lack of recognition. Awareness of this potentially hazardous complication of rifampin therapy is encouraged, especially since increasing numbers of patients infected with the human immunodeficiency virus, who may have diarrhea from other etiologies, require rifampin therapy.

Pyrazinamide, an antituberculous drug discovered in 1952, was first considered as a toxic drug. As it appeared as a bactericidal drug for the organisms inside macrophages, its usefulness has been re-appraised. In combination with other bactericidal drugs, it contributes to speed up the sterilization of tuberculous lesions. A review of the more recent clinical trials allows to assess the real toxicity of Pyrazinamide. Prescribed at a daily dosage of 30 to 35 mg/kg (1,5 to 2 g daily), it gives no major side effects.

The aim of this study was to assess the frequency of gastrointestinal side effects (GSE) and hepatotoxicity in patients treated with rifampicin for an osteoarticular infection and to determine if there is an association between rifampicin plasma concentrations and side effects. Rifampicin plasma concentrations were prospectively measured before (trough concentration, C(0)) and 2 +/- 0.5 h (peak concentration, C(2)) after drug intake. The presence of GSE, the alanine transferase (ALT) value, and concomitantly administered medications were recorded on the day rifampicin concentrations were measured. C(0) and C(2) were compared for differences regarding the presence or absence of side effects. Multivariate analysis was performed, with associated medications being taken into account. Seventy C(0) and 57 C(2) values were measured in 46 adults after a median treatment of 8 days (range, 1-179). Wide inter-individual variability was observed for C(0) and C(2). Thirteen (28%) patients reported GSE at least once. When GSE occurred, C(0) (median, 1 mg L(-1); range, 0.1-9.9 mg L(-1)) and C(2) (median, 10.3 mg L(-1); range, 1.8-40.3 mg L(-1)) were similar to C(0) (median, 0.6 mg L(-1); range, 0.1-10.3 mg L(-1)) and C(2) (median, 10.9 mg L(-1); range, 2.9-29.0 mg L(-1)) without GSE. The ALT value was more than normal in only three patients (6.5%) after rifampicin treatment began. The patients received no different associated medications whether or not GSE were present. Multivariate analysis showed no association between rifampicin plasma concentrations and GSE. GSE occur frequently in patients receiving rifampicin for osteoarticular infection but without an association with rifampicin plasma concentrations. Thus, therapeutic drug monitoring of rifampicin is irrelevant in the management of GSE.

To date, no randomized trial to address the use of adjunctive rifampin in addition to metronidazole for the treatment of Clostridium difficile-associated diarrhea has been reported. Rifampin has excellent in vitro activity against C. difficile and penetrates into cellular materials where the organisms may persist.. This was a prospective, randomized, single-blinded study of 39 patients that compared therapy with metronidazole alone versus therapy with metronidazole and rifampin for 10 days to treat laboratory-confirmed primary episode C. difficile-associated diarrhea. Twenty patients were randomly assigned to the metronidazole group, and 19 were randomly assigned to the metronidazole and rifampin group. Data were analyzed by intention-to-treat analysis using the 2-tailed Kaplan-Meier method and the log-rank test.. Adjunctive rifampin treatment for 10 days, compared with treatment with metronidazole alone for 10 days, was associated with a similar median time to symptom improvement (9.0 days vs. 6.5 days; P=.74), a similar median time to first relapse (26 days vs. 16 days; P=.23), a similar proportion of patients with relapse by study day 40 (42% vs. 38%; P=1.0), and a similar proportion of patients experiencing nonfatal adverse events (37% vs. 40%; P=.55). There were a significantly higher number of deaths in the metronidazole and rifampin group, compared with the metronidazole group (6 of 19 patients vs. 1 of 20 patients; P=.04), but there were fewer laboratory-confirmed relapses by study day 40 (2 vs. 4; P=.66).. We conclude that there is no role for routine rifampin as an adjunct to treatment with metronidazole for hospitalized patients with C. difficile-associated diarrhea. The cure rates for both treatment groups remain unacceptably low, and better treatments are urgently needed.

The combination therapies recommended by the World Health Organization for treatment of brucellosis are doxycycline plus rifampicin or doxycycline plus streptomycin. Although highly successful results have been obtained with these two regimens, relapse rates as high as 14.4%. The most effective and the least toxic chemotherapy for human brucellosis is still undetermined. The aim of the present study was to investigate the efficacy, adverse effects and cost of ofloxacin plus rifampicin therapy, and doxycycline plus rifampicin therapy and evaluate in the treatment of brucellosis.. The open trial has been carried out prospectively by the two medical centers from December 1999 to December 2001 in Duzce region Turkey. The diagnosis was based on the presence of signs and symptoms compatible with brucellosis including a positive agglutination titre (>/=1/160) and/or a positive culture. Doxycycline and rifampicin group consisted of 14 patients who were given doxycycline 200 mg/day plus rifampicin 600 mg/day during 45 days and this group Ofloxacin plus rifampicin group was consisted of 15 patients who were given ofloxacin 400 mg/day plus rifampicin 600 mg/day during 30 days.. Regarding clinical and/or demographic characteristics no significant difference was found between two groups of patients that underwent two different therapeutic regimens. At the end of the therapy, two relapses were seen in both groups (p = 0.695). Although duration of therapy was two weeks shorter in group treated with rifampicin plus ofloxacin, the cure rate was similar in both groups of examinees. Fever dropped more rapidly in the group that treated with rifampicin plus ofloxacin, 74 +/- 30 (ranges 48-216) vs. 106 +/- 26 (ranges 48-262) hours (p = 0.016).. Ofloxacin plus rifampicin therapy has advantages of shorter treatment duration and provided shorter course of fever with treatment than in doxycycline plus rifampicin therapy. However, cost of ofloxacin plus rifampicin treatment is higher than doxycycline plus rifampicin treatment. Because of the similar effects, adverse effects and relapses rates between two regimens, we still advice doxycycline plus rifampicin for the treatment of brucellosis for countries, which have limited resources.

The development of rifaximin- and rifampicin-resistant intestinal coliforms was studied in 27 subjects receiving rifaximin for 3 days by plating stool samples on media containing rifaximin 200 mg/L or rifampicin 64 mg/L before treatment (day 0), after treatment was completed (day 3), and after a further 2 days (day 5). The susceptibility of enterococci grown on day 0 and day 3 was also studied in 71 subjects. Significant increases in antimicrobial-resistant coliform flora were not seen in either the rifaximin-treated or the placebo-treated subjects. Enterococci recovered pre- and post-treatment showed similar susceptibilities. Rifaximin did not select for significant resistance in the Gram-negative and Gram-positive intestinal flora during therapy.

To test the hypothesis that antituberculous drug disposition is altered in patients with AIDS, we studied the steady-state pharmacokinetics of isoniazid (300 mg/d), rifampin (600 mg/d), and pyrazinamide (1,500 mg/d) in 29 adults (14 patients infected with human immunodeficiency virus [HIV] and 15 non-HIV-infected patients) with tuberculosis in Nairobi, Kenya. Intestinal integrity was assessed with xylose. Neither HIV infection nor diarrhea accounted for the interpatient variability in the area-under-the-plasma concentration vs. time curve (AUC), the maximum concentration, or the terminal half-life (t1/2) of isoniazid, rifampin, and pyrazinamide. No significant association between HIV infection or diarrhea and pharmacokinetics was seen for any of the compounds. In addition, neither the AUC nor the t1/2 of any of these drugs reflected interpatient differences in CD4 lymphocyte counts. Xylose absorption was uniformly low. We did not demonstrate that HIV infection, diarrhea, or CD4 lymphocyte counts contributed significantly to the variability in pharmacokinetics of isoniazid, rifampin, and pyrazinamide in TB patients in Nairobi.

The oral dose recommendation for FK506 (Fujisawa Pharmaceutical, Deerfield, IL) after liver transplantation has, to date, made no distinction between adult and pediatric patients. Sixteen pediatric and 33 adult liver transplant patients treated long term with oral FK506 were studied. Initial FK506 doses were 0.3 mg/kg/day p.o. or 0.15 mg/kg/day i.v. Thereafter, doses were adjusted to achieve therapeutic FK506 serum levels (0.5-3.0 ng/ml, ELISA liquid/liquid separation) and to maintain an acceptable serum creatinine. FK506 (in mg/kg/day), FK506 levels, and liver function were assessed at monthly intervals on outpatient visits. The mean age of 16 pediatric patients was 5.3 +/- 3.5 years and of 33 adult patients was 49 +/- 12 years. Mean days of FK506 therapy were 284 +/- 136 for pediatric patients and 239 +/- 112 for adult patients. For each time period, pediatric patients required a significantly higher dose of FK506 compared to adult patients (P < 0.001). The overall mean pediatric dose for the first year was 0.46 +/- 0.4 mg/kg/day compared to the mean adult dose of 0.13 +/- 0.01 mg/kg/day. The ratio of pediatric to adult oral FK506 dose requirements ranged from 2.7 to 4.4 over the 1 year of followup. FK506 levels monitored at the same time points showed no significant differences at any month between pediatric and adult patients. We conclude that the oral dose per kilogram per day of FK506 required to maintain similar FK506 levels is significantly greater in pediatric patients compared to adult recipients during the first year of follow-up. Pediatric recipients require substantially more, and adult recipients substantially less, than the recommended oral FK506 dose to achieve a therapeutic effect.

Clostridium difficile infection (CDI) is a leading cause of healthcare-associated diarrhea worldwide. In this study, risk factors associated with the development of severe-complicated and recurrent outcomes in CDI patients in different age groups, including the non-elderly, were assessed in a third-level hospital.. CDI cases were detected by clinical data and polymerase-chain-reaction (PCR). Clinical, demographic, epidemiological, and microbiological risk factors for CDI were evaluated.. During the study period, 248 out of 805 patients with nosocomial diarrhea were diagnosed with CDI and the majority were severe-complicated cases (87.90%). Female gender (OR 3.19, 95% CI 1.19-8.55, p = 0.02) and lymphoma (OR 3.95, 95% CI 1.03-15.13, p = 0.04) were risk factors for severe-complicated CDI. Mature adulthood (51-60 years) (OR 5.80, 95% CI 1.56-21.62, p = 0.01), previous rifampicin use (OR 7.44, 95% CI 2.10-26.44, p = 0.00), and neoplasm (solid malignant neoplasm or hematological malignancies) (OR 4.12, 95% CI 1.01-16.83, p = 0.04) were risk factors for recurrent infection. Autoimmune disorders (OR 6.62, CI 95% 1.26-34.73, p = 0.02), leukemia (OR 4.97, 95% CI 1.05-23.58, p = 0.04), lymphoma (OR 3.79, 95% CI 1.03-12.07, p = 0.04) and previous colistin treatment (OR 4.97, 95% CI 1.05-23.58, p = 0.04) were risk factors for 30-day mortality.. Newly identified risk factors for recurrent CDI were rifampicin treatment and age between 51 and 60 years; colistin treatment was identified as a risk factor for 30-day mortality. Previously identified risk factors for severe-complicated CDI were confirmed, but with a major impact on non-elderly patients.

The molecular epidemiology of C. difficile strains causing disease in South Africa is currently unknown. Previously, multidrug resistant ribotype (RT)017 strains were those most commonly isolated from patients with diarrhoea attending Groote Schuur Hospital in Cape Town, South Africa. This larger study aimed to investigate the molecular epidemiology and antibiotic susceptibility profiles of C. difficile strains in the greater Cape Town and regional areas. C. difficile strains were isolated from patients with diarrhoea attending hospitals in the Western Cape region of South Africa that tested positive using the GeneXpert CDiff diagnostic test. Ribotyping and multilocus variable-number tandem-repeat analysis (MLVA) were used to type isolates, and their susceptibilities to several antibiotics were determined by gradient diffusion test strips. A total of 269 non-repeat C. difficile isolates were obtained. A large proportion of isolates (64.3 %) belonged to the RT017 group, many of which were clonally related when investigated by MLVA. RT017 strains were particularly prevalent in patients attending specialist tuberculosis (TB) hospitals. The majority of RT017 isolates were co-resistant to moxifloxacin and rifampicin, two antibiotics which are used intensively during anti-TB therapy. Non-RT017 strains were generally susceptible to both antibiotics. Resistance to erythromycin was observed for both groups of strains. RT017 C. difficile strains are the most commonly isolated strains from patients attending healthcare facilities in the greater Cape Town and regional areas. The presence of multidrug resistant RT017 strains in patients with diarrhoea attending local TB hospitals reflects a potential reservoir for future infections.

A 53-year-old woman was admitted to our hospital due to abdominal pain, diarrhea, and shunt occlusion caused by dehydration. She had undergone hemodialysis due to diabetic nephropathy over a ten-year period. She was hospitalized again with fever and a persistent high serum CRP level. We started antibiotic administration using cefotiam hexetil hydrochloride because of ascites and peritoneum thickening observed by abdominal computed tomography. Although her symptoms, such as abdominal pain and diarrhea, improved after the administration of antibiotics, the ascites and the peritoneum thickening did not improve. On the fourth hospital day, we attempted ascites aspiration to investigate the etiology of the peritonitis. Cytological examination suggested tuberculous peritonitis because of predominant macrophage cell proliferation, a high level of ADA concentration, and a high level of CA125 of ascites. Although QuantiFERON-tuberculosis (QFT) and the Gaffky scale were negative, we started multidrug therapy (isoniazid + rifampicin + pyrazinamide + ethambutol) on the 20th hospital day. She was finally diagnosed as mycobacterium tuberculous peritonitis based on biopsy of the tissue of the ileum and the results of colonoscopy. Administration of antituberculosis chemotherapy improved abdominal fullness and ascites and the patient was discharged on the 97th hospital day. Moreover Kuno et al. reported that serum soluble interleukin-2 receptor(sIL-2R) and CA-125 levels can be used to monitor the response to anti-tuberculosis treatment. In this case, we use these markers to monitor the response to treatment. We experienced a case of tuberculous peritonitis undergoing hemodialysis. Tuberculosis should be suspected when patients undergoing dialysis have long-term fever of unknown etiology. There are many reports stating that the sensitivity and specificity of QuantiFERON-tuberculosis (QFT) and sputum culture are low in latent tuberculosis infection of dialysis patients. Accordingly it is necessary to diagnose mycobacterium tuberculous peritonitis comprehensively by the clinical symptoms and image analysis.

Abstract: Mycobacterium avium paratuberculosis (Map) was cultured from the feces of a wild-caught, female, adult Southern black rhinoceros. The animal, which presented with a 4-mo history of diarrhea and weight loss, was prescribed a course of antimycobacterial drugs. The clinical signs resolved, and the feces were repeatedly culture negative thereafter. Although the Rhinocerotidae are likely to be resistant to Johne's disease, this case raises the possibility that they can become transiently infected with the causative organism.

This was an in vitro study to analyse the susceptibility of Clostridium difficile isolates to rifampin and rifaximin.. Stool samples from patients who had nosocomial diarrhoea and C difficile toxin B at a university hospital between August 2006 and December 2007 were cultured for C difficile. Susceptibility of C difficile isolates to rifaximin and rifampin was determined by agar dilution and E strips, respectively. C difficile isolates were analysed via PCR for genes encoding toxins A and B, for binary toxin (BT), and for partial deletions of the tcdC gene (tcdC-del).. Rifaximin exhibited high-level activity against 359 C difficile isolates, with MIC(50) <0.01 microg/ml and MIC(90) 0.25 microg/ml; rifampin had MIC(50) <0.002 microg/ml and MIC(90) 4 microg/ml. Among isolates analysed, 55 (15%) were positive for BT and tcdC-del. 28 (8% of 359) isolates were resistant to rifampin (> or = 32 microg/ml), of which 6 (2% of 359) were resistant to rifaximin and rifampin with MIC values > or = 32 microg/ml. 2 of the 28 isolates resistant to rifampin were A(+)/B(+)/BT(+)/tcdC-del(+), 5 were A(+)/B(+)/BT(-)/tcdC-del(+), 4 were A(+)/B(+)/BT(+)/tcdC-del(-), 13 were A(+)/B(+)/BT(-)/tcdC-del(-), and 4 had no detectable toxin genes. Of the 11 isolates resistant to rifaximin alone, 1 was A(+)/B(+)/BT(-)/tcdC-del(+), 2 were A(+)/B(+)/BT(+)/tcdC-del(-), 6 were A(+)/B(+)/BT(-)/tcdC-del(-), and 2 had no detectable toxin genes.. The study demonstrates that rifaximin has high-level activity against C difficile in vitro. Determination of resistance to rifampin by E strip did not predict rifaximin resistance.

Clofazimine enterophathy is a serious complication of clofazimine when used at high doses for treatment of type 2 lepra or or erythema nodosum leprosum. Objective. A woman is presented who had a delayed diagnosis of leprosy, persistent type 2 lepra reaction and lethal clofazimine enteropathy.. A 31-year-old woman presented leprosy symptoms over a 16-year period without medical diagnosis of her disease. During this period, type 2 lepra episodes occurred, but were not accurately diagnosed. These episodes became more severe during her second pregnancy. The patient and her family were interviewed, and her clinical history reviewed.. After twelve years of medical consults, lepromatous leprosy was diagnosed, based on perforation of her nasal septum, with a bacterial index of 5. Her husband and a 12-year-old daughter have leprosy symptoms. During multidrug therapy, she presented with repeated type 2 lepra reaction episodes for which she received daily clofazimine 400 mg doses. Two months after this treatment, severe and frequent episodes of intense abdominal pain began to occur. These persisted for more than a year and were managed with in-hospital administration of several classes of painkillers and antispasmodic medication, including morphine. She also presented with sporadic diarrhea, constipation, nausea, weight loss and mesenteric adenopathies. She died finally due to this intestinal condition. No autopsy was performed.. The patient's clinical presentation suggested a clofazimine-induced lethal enteropathy, a complication not previously seen in Colombia. This connection was not recognized by the medical officers that treated the patient.

A case of intestinal tuberculosis affecting the jejunum (with perforations) and the colon is presented. The objective is to highlight the challenges medical practitioners face in making a timely diagnosis of intestinal tuberculosis. It also aims to raise awareness that chronic diarrhoea and weight loss are common symptoms of colonic tuberculosis. A 26 year old university student was admitted with a three month history of diarrhoea anorexia and weight loss having been seen and treated for typhoid in several hospitals without improvement. Colonoscopy and biopsy was non conclusive. He later developed subacute intestinal obstruction that did not respond to conservative treatment. Explorative laparotomy revealed jejunal perforations with localised absesses, peritoneal adhesions with caseous nodules and mesenteric Iymphadenopathy. Histology of resected specimens was positive for mycobacterium tuberculosis.

The main characteristics of clindamycin are adequate for treatment of osteoarticular infections (OAI): good bone diffusion, broad spectrum of antibacterial activity and oral use.. A number of 61 patients was included in an observational retrospective study of efficacy and tolerance.. Prosthetic infections accounted for 50.8% of the cases and chronic osteitis for 36.1%. The causative micro-organisms were Staphylococci (72.2%) and Streptococci (15.3%); 86.5% of these strains were susceptible to erythromycin, 9.6% were erythromycin resistant and susceptible to lincomycin. Clindamycin was associated with either ofloxacine, rifampicin, or teicoplanin in 88.5% and the average course duration was 101 days. A surgical procedure was performed in 84% of cases. Complete cure was obtained in 91.1% at 18 months of follow up. Only one cutaneous rash and one Clostridium difficile-associated diarrhea occurred. The other adverse effects were gastrointestinal in 36%, cutaneous in 6.6%, and hematological in 1.6%, but did not lead to discontinuation of therapy.. Clindamycin can be used in OAI in association with or as an alternative to rifampicin, fluoroquinolones, or glycopeptides according to microbiological data.

The clinical form of the protothecosis in animals is most commonly observed in countries with a warm and moist climate, only a few reports describing cases of this infection in cooler areas of the word exist. In the case of large bowel infection in dogs, organisms colonise the lamina propria and submucosa causing severe necrotizing ulcerative or haemorrhagic enterocolitis. In this report the intestinal form of protothecosis in 1.5-year-old, male, mongrel dog with chronic hemorrhagic diarrhoea is described. History revealed that the dog spent some time in the countryside and afterwards diarrhoea with fresh blood appeared. The results of morphological and biochemical blood analysis were normal and stool examination did not reveal the presence of parasites. Treatment with anti-inflammatory doses of prednisone, metronidazole and enrofloxacin followed by sulphasalazine resulted in a short period of improvement, but was followed by deep deterioration of animal status. Because of the relapse diagnostic laparotomy was performed and tissue samples of the colon and jejunum were obtained for histopathology. On the basis of the clinical signs, exploratory laparotomy findings and histopathology the diagnosis of canine intestinal prototecosis was made and medical treatment was recommended.

To present a case of successful emergency endovascular repair of a ruptured, probably mycotic, thoracoabdominal aortic aneurysm (TAAA) with a stent-graft deliberately covering the celiac axis.. A 79-year-old woman with significant pulmonary comorbidity presented with a ruptured mycotic TAAA extending to the celiac axis. The aneurysm was excluded with a stent-graft soaked in rifampicin and deployed to deliberately occlude the celiac axis for effective distal sealing and fixation. The patient recovered well and was prescribed antibiotic treatment for up to 6 months.. Endovascular repair of a ruptured TAAA may be a life-saving option. In emergency situations when poor distal anatomy is present, covering the celiac artery with the stent-graft should be considered.

Pseudomembranous colitis is known to develop with long-term antibiotic administration, but antitubercular agents are rarely reported as a cause of this disease. We experienced a case of pseudomembranous colitis associated with rifampin. The patient was twice admitted to our hospital for the management of frequent bloody, mucoid, jelly-like diarrhea and lower abdominal pain that developed after antituberculosis therapy that included rifampin. Sigmoidoscopic appearance of the rectum and sigmoid colon and mucosal biopsy were compatible with pseudomembranous colitis. The antitubercular agents were discontinued and metronidazole was administered orally. The patient's symptoms were resolved within several days. The antituberculosis therapy was changed to isoniazid, ethambutol and pyrazinamide after a second bout of colitis. The patient had no further recurrence of diarrhea and abdominal pain. We report here on a case of pseudomembranous colitis associated with rifampin.

To determine whether foals with pneumonia that were treated with erythromycin, alone or in combination with rifampin or gentamicin, had a higher risk of developing adverse effects, compared with foals treated with trimethoprim-sulfamethoxazole (TMS), penicillin G procaine (PGP), or a combination of TMS and PGP (control foals).. Retrospective study.. 143 foals < 240 days old.. Information on age, sex, breed, primary drug treatment, total days of treatment with the primary drug, and whether the foal developed diarrhea, hyperthermia, or respiratory distress was obtained from the medical records. Relative risk (RR) and attributable risk (AR) were calculated to compare risk of adverse reactions between foals treated with erythromycin and control foals.. Only 3 (4.3%) control foals developed diarrhea; none developed hyperthermia or respiratory distress. Foals treated with erythromycin had an 8-fold risk (RR, 8.3) of developing diarrhea, compared with control foals, and increased risks of hyperthermia (AR, 25%) and respiratory distress (AR, 15%).. Results suggest that use of erythromycin to treat foals with pneumonia was associated with an increased risk of diarrhea, hyperthermia, and respiratory distress, compared with use of TMS or PGP.

Proliferative enteropathy (PE) is a transmissible enteric disease caused by Lawsonia intracellularis. An outbreak of equine PE was diagnosed in foals from 3 breeding farms. Most foals had been weaned prior to the appearance of clinical signs, which included depression, rapid and marked weight loss, subcutaneous oedema, diarrhoea and colic. Poor body condition with a rough haircoat and a potbellied appearance were common findings in affected foals. Respiratory tract infection, dermatitis and intestinal parasitism were also found in some foals. Haematological and plasma biochemical abnormalities included hypoproteinaemia, transient leucocytosis, anaemia and increased serum creatinine kinase concentration. Postmortem diagnosis of PE was confirmed on 4 foals based on the presence of characteristic intracellular bacteria within the apical cytoplasm of proliferating crypt epithelial cells of the intestinal mucosa, using silver stains, and by results of PCR analysis and immunohistochemistry. Antemortem diagnosis of equine PE was based on the clinical signs, hypoproteinaemia and the exclusion of common enteric infections. Faecal PCR analysis was positive for the presence of L. intracellularis in 6 of 18 foals tested while the serum of all 7 foals with PE serologically evaluated had antibodies against L. intracellularis. Most foals were treated with erythromycin estolate alone or combined with rifampin for a minimum of 21 days. Additional symptomatic treatments were administered when indicated. All but one foal treated with erythromycin survived the infection. This study indicates that equine PE should be included in the differential diagnosis of outbreaks of rapid weight loss, diarrhoea, colic and hypoproteinaemia in weanling foals.

We present a case of significant over-anticoagulation temporally associated with a bout of protracted diarrhea in a patient on warfarin therapy. Cholestyramine was utilized to interrupt the enterohepatic recycling of warfarin and for its antidiarrheal effects to prevent gastrointestinal vitamin K wasting. Cholestyramine enabled the use of very low doses of sc vitamin K1 (2 mg total) with subsequent attainment of a therapeutic International Normalized Ratio in 39 h.

Reports suggest that antituberculosis drugs are malabsorbed in patients with advanced HIV disease.. To evaluate the pharmacokinetics of antituberculosis agents in HIV-seropositive patients at different stages of disease.. Parallel study.. Two hospital outpatient clinics.. 12 healthy volunteers, 12 patients with asymptomatic HIV disease, 12 patients with symptomatic HIV disease, and 12 patients with symptomatic HIV disease and diarrhea.. Drug plasma concentrations were measured over 24 hours on day 4 of concurrent therapy.. Oral isoniazid (300 mg/d), rifampin (600 mg/d), pyrazinamide (1000 mg/d), and ethambutol (1000 mg/d).. Reduced total drug exposure to rifampin and pyrazinamide was associated with D-xylose malabsorption in persons with HIV infection or AIDS. Peak drug exposure to isoniazid was lower in patients with diarrhea.. Reduced total drug exposure may be related to malabsorption in persons with HIV infection or AIDS.

Proteus mirabilis isolates obtained from urine and faeces showed high invasion levels into several human epithelial cell lines in gentamicin assays. Invasion efficiencies of isolate 102 from a monkey with diarrhoea equalled or even exceeded those of Salmonella typhi strain Ty2 (6.3 to 13.8% of the inoculum). Vegetative, non-swarming P.mirabilis invaded epithelial cells efficiently and were found in endosomes and free in the cytoplasm. Although inhibition of eukaryotic protein synthesis by cycloheximide did not reduce bacterial uptake, inhibition with bacteriostatic antibiotics of bacterial protein-, RNA-, or DNA-synthesis reduced invasion drastically. Involvement of eukaryotic structures and processes in internalization was determined by using various inhibitors in the invasion assay. Uptake of P.mirabilis isolated from urine into gut (INT 407, HCT-8) cells and bladder (T24) cells was dramatically inhibited only by microfilament depolymerization. Internalization of faecal isolate 102 into gut or bladder epithelial cells was inhibited by depolymerization of microfilaments or microtubules. Engulfment of isolate 102 into T24 bladder cells was also reduced by inhibition of receptor-mediated endocytosis. Interference with endosome acidification decreased the number of intracellular bacteria of isolate 102 in all three cell lines. These results suggest that P.mirabilis isolates from different sources are internalized by epithelial cells by different eukaryotic processes, and that these processes can vary between cell lines.

The susceptibility to chloramphenicol, clindamycin, erythromycin, rifampicin and tetracycline of 308 isolates of Clostridium difficile from various origins was determined by a disc diffusion susceptibility testing and the results were compared with the serogroup of the strains. For the five antimicrobials, there was a clear-cut separation between susceptible and resistant strains. Some correlation between resistance and serogroup was found. Almost all of the 161 isolates of serogroups A, F, G, H and X were susceptible to all antibiotics. The 32 toxigenic isolates of serogroup C were characterized by a typical resistance pattern which could be used for typing purposes. Other serogroups showed variable patterns. The review of 64 cases of antibiotic associated diarrhoea showed that these differences in susceptibility could have clinical implications: all seven cases due to clindamycin were caused by a clindamycin resistant strain of serogroup C, whereas cases associated with other antibiotics were distributed among various serogroups.

Seven patients with multiple bacteriologic and symptomatic relapses of Clostridium difficile-associated diarrhea and/or colitis were treated with vancomycin and rifampin in combination. Diarrhea and abdominal pain promptly resolved in all, and neither C. difficile nor its toxin could be recovered from their stools shortly after therapy. However, stools of all patients subsequently became culture-positive for C. difficile and occasionally had demonstrable cytotoxin. Except in one instance following oral antibiotic use, all patients remained free of symptoms. Resistance to either vancomycin or rifampin was not encountered. Biotyping of isolates with clostridial bacteriophages and bacteriocins suggested true relapse with the same organism in all patients studied, rather than reinfection with another strain. Vancomycin and rifampin in combination appear to be useful in the therapy of relapsing antibiotic-associated diarrhea due to C. difficile.

The effects of several plasmids, including cloning vectors and R factors, on the virulence of Vibrio cholerae CA401R were determined by measuring the dose-related diarrheal response in orally challenged infant mice. The plasmids were also examined for their effects on the colonization ability of strain CA401R by joint infection experiments with a spectinomycin-resistant CA401 strain as an internal standard. One V. cholerae R factor, pVH2, enhanced the diarrheal response, while R factors Rts1 and pVH1 reduced it; plasmids RP4, pRK290, Sa, pSJ8, pSJ5, and pBR328 had no effect. The ability of the plasmids to affect in vitro toxin production by CA401R was variable. Cells containing large plasmids all showed a modest decrease in colonization ability. These results showed that some plasmids affected V. cholerae virulence, but that the cloning vectors pBR328, RP4, and pRK290 did not.

Changes of pharmacokinetics of rifampicin (20 mg . kg-1 orally) were seen in rabbits pretreated with 0.02, 0.2 and 2.0 micrograms . kg-1 of endotoxin S. typhimurium given intravenously. The animals served as their own controls. The two higher endotoxin doses induced significantly lower plasma levels and changes in the absorption and elimination phase. After the lowest endotoxin dose the results were variable. Tolerance to pyrogenicity of endotoxin, produced by daily toxin administration abolished the otherwise induced changes in rifampicin pharmacokinetics.
