ABSTRACT
BACKGROUND: Chronic hepatitis C causes chronic hepatic inflammation, which can lead to cirrhosis, terminal liver failure, and hepatocellular carcinoma. The treatment aims to achieve viral clearance, but the usage of pegylated interferon and ribavirin is linked to side effects such as severe weight loss, which can lead to complications and treatment discontinuation. The aim of this study was to investigate which anthropometric measures were more affected in patients with chronic hepatitis C during 24 weeks of treatment with pegy lated interferon and ribavirin. Then, the influence of age, sex, hepatic fibrosis stage, and ribavirin doses on each measure was also evaluated. METHODS: Seventy-six patients were included and their weight, triceps skin fold thickness, arm circumference, middle-arm muscle circumference, and corrected arm muscle area were measured before and after 24 weeks of treatment. Epidemiological data and liver biopsy findings were obtained from patients' records. The sample was divided into two groups: one with advanced hepatic fibrosis and another group with mild to moderate fibrosis. Comparisons into each group were made using Wilcoxon or paired tests. After that, a linear regression model was applied to estimate the anthropometric changes during the treatment according to age, sex, hepatic fibrosis stage, and ribavirin doses. RESULTS: The subjects suffered reductions of important anthropometric measures, mainly related to fat mass (p<0.001).Some decrease of fat-free mass was also observed in subjects with advanced fibrosis. The statistic model showed that age and sex were more associated with the anthropometric changes observed. CONCLUSIONS: In conclusion, the antiviral treatment caused loss of relevant anthropometric measures, and the model proposed was able to estimate some of them

Cytomegalovirus (CMV) disease is a major cause of morbidity and mortality in solid organ transplantation. Disseminated toxoplasmosis after liver transplantation is a rare but fatal event. Serologic screening of the donor and the recipient is essential to prophylactic management, early diagnosis and therapeutic strategies to minimize the consequences of these infections. The aim of the present study was to determine the seroprevalence of CMV and Toxoplasma gondii (TG) in a Brazilian liver transplant waiting list (LTWL). Serological data were collected from 44 candidates on the LTWL between May 2003 and November 2004. Serological investigation of antibodies IgM and IgG against CMV (anti-CMV) and TG (anti-T. gondii) was performed using fluorometry commercial kits. IgG anti-CMV was positive in 37 patients (94.9 percent) out of 39 available results. There were not IgM anti-CMV positive results. Out of 36 analyzed patients, 22 (61.1 percent) presented positive IgG anti-T. gondii and none had positive IgM anti-T. gondii. The high CMV seroprevalence among our LTWL reinforces the need for appropriate protocols to avoid related complications, like reactivation and superinfection by CMV. Environmental and drug prophylactic strategies against primary infection and reactivation, as well as early diagnosis and treatment of toxoplasmosis complications, are essential for the good outcome of transplant patients.
