RESUMO
Recently, a controversial approach suggesting the early treatment of chronic infection with hepatitis B "e" antigen-positive patients with hepatitis B virus (HBV) infection, has been proposed. The objective of this study is to systematically review medical literature regarding treatment of HBV infection in adult chronic infection with HBeAg-positive patients. A systematic review was performed according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. Original studies that evaluated the effect of antivirals in adult chronic infection with HBeAg-positive patients were included. The outcomes of interest were viral load suppression, the loss/seroconversion of HBeAg, the loss/seroconversion of hepatitis B surface antigen, and the development of cirrhosis or hepatocellular carcinoma. The search for eligible studies was performed in Excerpta Medica dataBASE, PubMed and Cochrane databases until January 2020, without language or date restriction. The risk of bias was evaluated using the Newcastle-Ottawa Scale for observational studies and the Revised Cochrane Risk-of-Bias Tool for randomized controlled trials. Two hundred ninety-six articles were retrieved. After analyzing titles and abstracts, 287 articles were excluded and nine were considered potentially eligible. From these, five were excluded after full-text analysis. Finally, four articles were included. Only two were randomized controlled trials. All studies were carried out in Asian patients. Results were variable with regard to viral load, negativation/seroconversion of HBeAg and HBsAg. One study demonstrated that treated patients developed cirrhosis or hepatocellular carcinoma less frequently than untreated individuals. Overall, the studies were of poor quality. In conclusion, the present systematic review demonstrated that, at present, there is not enough evidence to recommend treating this population of patients.

INTRODUCTION AND OBJECTIVES: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disorder in western countries. It is often related to metabolic syndrome, presenting an increased risk of advanced liver disease and cardiovascular-related death. In some etiologies of chronic liver disease, thrombocytopenia has been associated not only with advanced stages of fibrosis but also with autoimmune disease. In NAFLD, however, its prevalence and related factors are still unknown. The aim of this study is to evaluate the prevalence of thrombocytopenia in NAFLD patients without cirrhosis and to investigate its related risk factors. PATIENTS AND METHODS: This was a retrospective study carried out in two tertiary hospitals in the South and Southeast regions of Brazil. Patients diagnosed with NAFLD by liver biopsy were included. Those with other causes of liver disease and/or cirrhosis were excluded. For analysis, patients were divided into two groups, with and without thrombocytopenia. Data was analyzed using a significance level of 5%. RESULTS: 441 non-cirrhotic patients with NAFLD (evaluated by liver biopsy) were included in the study. The prevalence of thrombocytopenia was 3.2% (14/441 patients). In the comparative analysis between groups, thrombocytopenia was associated with male sex (p=0.007) and level of hemoglobin (p=0.023). CONCLUSION: Thrombocytopenia is an infrequent event in NAFLD patients without cirrhosis and is related with male sex and higher hemoglobin levels.

INTRODUCTION AND AIM: The gold-standard for fibrosis diagnosis in non-alcoholic fatty liver disease (NAFLD) is liver biopsy, despite its invasive approach, sampling limitations and variability among observers. The objective was to validate the performance of non-invasive methods (Fibroscan™; APRI, FIB4 and NAFLD score) comparing with liver biopsy in the evaluation of liver fibrosis in patients with NAFLD. MATERIAL AND METHODS: NAFLD patients ≥18 years of age who were submitted to liver biopsy were included and evaluated at two reference tertiary hospitals in Brazil with transient hepatic elastography (THE) assessment through Fibroscan™, APRI, FIB4 and NAFLD scores were determined. Sensitivity, specificity, positive (PPV) and negative (NPV) predictive values for the diagnosis of advanced fibrosis were calculated to evaluate the performance of these non-invasive methods in NAFLD patients, adopting liver biopsy as the gold standard. RESULTS: A total of 104 patients were studied. At three different cutoff values (7.9, 8.7 and 9.6kPa) THE presented the highest sensitivity values (95%, 90% and 85% respectively), and the highest NPV (98%, 96.4% and 95.1% respectively) for the diagnosis of advanced fibrosis. It also presented the highest AUROC (0.87; CI 95% 0.78-0.97). CONCLUSION: When compared to the gold standard, transient hepatic elastography presented the best performance for the diagnosis and exclusion of advanced fibrosis in patients with NAFLD, overcoming APRI, FIB4 and NAFLD score.

OBJECTIVE: To identify the incidence of pelvic infection after miscarriage undergoing uterine evacuation in a tertiary hospital in southern Brazil and to compare with the international literature. METHODS: we reviewed electronic medical records of the Hospital de Clinicas de Porto Alegre of all patients who underwent uterine evacuation for miscarriage between August 2008 and January 2012 were reviewed. We included all patients submitted to uterine curettage due to abortion and who had outpatient visits for review after the procedure. We calculated emographic and laboratory data of the study population, number needed for treatment (NNT) and number needed to harm (NNH). RESULTS: of the 857 revised electronic medical records, 377 patients were subjected to uterine evacuation for miscarriage; 55 cases were lost to follow-up, leaving 322 cases that were classified as not infected abortion on admission. The majority of the population was white (79%); HIV prevalence and positive VDRL was 0.3% and 2%, respectively. By following these 322 cases for a minimum of seven days, it was found that the incidence of post-procedure infection was 1.8% (95% CI 0.8 to 4). The NNT and NNH calculated for 42 months were 63 and 39, respectively. CONCLUSION: The incidence of post-abortion infection between August 2008 to January 2012 was 1.8% (0.8 to 4).

OBJETIVO: Identificar a incidência de infecção pélvica após aborto espontâneo submetido a esvaziamento uterino num hospital terciário do sul do Brasil e comparar com a literatura internacional. MÉTODOS: Os prontuários eletrônicos do Hospital de Clínicas de Porto Alegre de todas as pacientes que foram submetidas ao esvaziamento uterino por abortamento entre agosto de 2008 e Janeiro de 2012 foram revisados. Foram incluídas no estudo todas as pacientes submetidas à curetagem uterina por abortamento e que tiveram consultas ambulatoriais de revisão após o procedimento. Os dados demográficos e laboratoriais da população estudada, number needed for treatment (NNT) e o number needed to harm (NNH) foram calculados. RESULTADOS: Dos 857 prontuários eletrônicos revistos, 377 pacientes foram submetidas ao esvaziamento uterino por abortamento; 55 casos foram perdidos no seguimento, restando 322 casos que foram classificados como aborto não infectado na admissão. A maioria da população era da raça branca (79%); a prevalência de HIV e VDRL positivos foi de 0,3 e 2%, respectivamente. No seguimento desses 322 casos, num período mínimo de 7 dias, verificou-se que a incidência de infecção pós-procedimento foi de 1,8% (IC95%0,8 a 4). O NNT e o NNH calculado para 42 meses foi de 63 e 39, respectivamente. CONCLUSÃO: A incidência de infecção pós-aborto entre agosto de 2008 a janeiro de 2012 foi de 1,8% (0,8 a 4). .
