Introduction and Objectives: To achieve WHO's goal of eliminating HCV, innovative strategies must be designed to diagnose and treat more patients. This study aimed to describe an implementation strategy to identify patients with HCV who were lost to follow-up (LTFU) and offer them re-linkage to Figure 1. Analysis of global DNA methylation. A) Representative dot blot using anti-5mC which recognizes global methylated DNA, anti-IgG as negative control and methylene blue staining as total DNA loading control. B) Graphs shows mean ± standard deviation of 5mC densitometry brand intensity of study groups. C) Graph that represents the percentage of global methylation of the DNA analyzed with ELISA.A one-way ANOVA statistical test and a Tukey post hoc test were performed. Group NT: only received vehicle; Group HCC: damage group induced by weekly administration of DEN and 2-AAF for 12 weeks; and Group HCC/PFD: which received the same treatment as Group HCC, plus PFD (300 mg/kg) (**p

ABSTRACT Background: Hepatitis C is an important health problem. In Brazil, 1-2 million people are infected. Despite this expressive number, and the availability of very successful treatment, many patients remained undiagnosed mainly because of the asymptomatic nature of the infection. Objectives: To describe epidemiological characteristics of HCV-infected patients seen at referral centers in Brazil, the source of referral, and the time spanned to reach a reference center, in order to improve the identification of undiagnosed patients. Methods: Multicenter observational, cross-sectional study carried out in 15 centers of Brazil, between January/2016 and June/2017. Data of patients with a confirmed diagnosis (anti-HCV and HCV-RNA) were collected by interview using standard questionnaires and by review of charts. Results: Two thousand patients were included; 55.1% were male, mean age 58 ± 11 years. Only 14.9% had higher education and 84.2% received up to five monthly minimum Brazilian wages (approximately US$260.00/month). The time between diagnosis and beginning of follow-up was 22.9 months. The most common reasons for testing were check-up (33.2%) and blood donation (19%). General practitioners diagnosed most of the patients (30.1%). Fibrosis stage was mainly evaluated by liver biopsy (61.5%) and 31.3% of the patients were cirrhotic at diagnosis. Conclusions: This multicenter Brazilian study showed that the mean time to reach a referral center for treatment was almost two years. Primary care physicians diagnoses most hepatitis C cases in the country. Population campaigns and medical education should be encouraged to intensify screening of asymptomatic individuals, considering the efficiency of check-ups in identifying new patients.

Background. The epidemiology and clinical characteristics of nonalcoholic fatty liver disease (NAFLD) in South America are not well known. Brazil is a largest country in this part of the world and the present study aimed to contribute with this information.Methods. This descriptive study included patients from medical centers around Brazil, who had diagnosis of NAFLD. They were selected from chart review and also prospectively in Hepatology out-clinics. Patients with history of alcohol intake and others liver diseases were excluded. Histological diagnosis included: steatosis or steatohepatitis (steatosis, ballooning of hepatocytes or fibrosis). The criteria to perform a liver biopsy was ALT or AST > 1.5 × normal levels.Results. A total of 1280 patients from 16 Brazilian centers and all five regions were included. The mean age was 49.68 ± 13.59 years; 53.3% were males and 85% were asymptomatic. Hyperlipidemia was observed in 66.8% cases, obesity in 44.7%, overweight in 44.4%, diabetes in 22.7%, and toxins exposure in 10%. Metabolic syndrome was observed in 41.3% cases. Elevated levels of ALT, AST and GGT were observed in 55.8%, 42.2% and 63.1% cases, respectively. Liver biopsy performed in 437 cases showed: isolate steatosis in 42% cases, steatohepatitis in 58% and 27% of them also presented fibrosis. Cirrhosis was observed in 15.4% and hepatocellular carcinoma in 0.7%.Conclusions. NAFLD in Brazil is more frequent in asymptomatic males; steatohepatitis with fibrosis and cirrhosis were a significant diagnosis. The genetic predisposition and lifestyle should be influenced in the spectrum; however these findings deserve a future investigation.
