Background Portal vein thrombosis (PVT) has been described in nearly 50% of patients who underwent oesophagogastric devascularization combined with splenectomy (EGDS), but no previous study has compared its occurrence in surgical and non-surgical groups. This study aimed to investigate PVT in hepatosplenic schistosomiasis (HSS) and its association with EGDS and upper variceal bleeding (UVB). Methods Retrospectively, 104 HSS individuals were enrolled. Following EGDS, the occurrence of PVT, mesenteric vein thrombosis (MVT), hospital admissions and UVB were recorded. Results EGDS was performed in 27 (26%) patients. PVT and MVT were detected in 30 (33%) and 8 (9.8%) patients, respectively. Patients who underwent EGDS were at greater risk of PVT (63% vs 19.7%; odds ratio [OR] 6.12 [95% confidence interval {CI} 2.3 to 16.1], p Conclusions EGDS was not associated with a decreased frequency of UVB when compared with the non-surgical approach but was an independent risk factor for PVT.

Background. Primary sclerosing cholangitis (PSC) is associated with a broad phenotypic spectrum in different populations from diverse ethnic and racial backgrounds. This study aimed to describe the clinical characteristics and outcomes of PSC in a multicenter cohort of patients from Brazil. Methods. Data from the Brazilian Cholestasis Study Group were retrospectively reviewed to assess demographic information and clinical characteristics of PSC, as well as the outcomes, such as transplantation-free survival. Results. This cohort included 210 patients. After excluding 33 (15.7%) patients with PSC and overlap syndrome of autoimmune hepatitis, 177 (97 males, median age 33 (21–42) years) with clear-cut PSC were eligible for this study. Most of the patients (n = 139, 78.5%) were symptomatic, and 104 (58.7%) had advanced PSC at the time of diagnosis. Concurrent inflammatory bowel disease was observed in 78 (58.6%) of the investigated patients (n = 133), and most of them had ulcerative colitis (n = 61, 78.2%). The 1- and 5-year survival free of liver transplantation or death were 92.3 ± 2.1% and 66.9 ± 4.2%, respectively, and baseline advanced PSC, pruritus, and elevated bilirubin levels were independent risk factors for the composite adverse outcome. Females were significantly older and had lower bilirubin levels than males at baseline, but survival was not associated with sex. Approximately 12.4% (n = 22) of patients with PSC died, and 32.8% (n = 58) underwent liver transplantation at a median follow-up time of 5.3 and 3.2 years. Conclusion. Multiethnic Brazilian PSC patients exhibited a less pronounced male predominance and a lower frequency of inflammatory bowel disease than Caucasians. Adverse outcomes were more frequent, probably due to advanced disease at baseline.

During the yellow fever (YF) outbreak in Brazil, many cases of fulminant hepatitis were seen, although mild to moderate hepatitis was mostly observed with complete recovery. This report presents a case of late-onset hepatitis due to YF relapse. The patient sought medical attention after jaundice recurrence 40 days after the first YF hepatitis episode. This case highlights the importance of patient follow-up after the complete resolution of YF symptoms and discharge.

Context Studies on epidemiology of hepatocellular carcinoma and modalities of therapy used to treat this condition are scarce in Brazil. Our aim was to characterize hepatocellular carcinoma according to etiology of the underlying chronic liver disease, and treatment modalities, in a referral center in Brazil. Methods All cases of hepatocellular carcinoma registered in the Department of Pathology during a 12-year period (1998-2010) were included. Demographic data, etiology of the underlying liver disease and treatment performed were collected. Results This case series included 215 patients, mean age 57.3 (± 14.1) years, 164 (76.2 %) male. Virus C and virus B infection were detected in 88 (43%) and 47 (23%) patients, respectively. Ethanol abuse alone or combined with other etiologies was identified in 64 (32%) individuals. Schistosomiasis was found in 18 (9%) patients. Liver transplantation was the treatment of choice in 112 (51%) patients. This procedure was more frequently performed in hepatitis C virus-related hepatocellular carcinoma (70%) than B virus-related hepatocellular carcinoma (17%). Tumor resection was performed in 40 (18%) individuals, ethanol injection or thermo ablation in 18 (14%), and chemoembolization in 14 (7%). In 40 (19.4%) patients no treatment was performed and this percentage remained constant over the years. Conclusions Chronic hepatitis C, followed by ethanol abuse and chronic hepatitis B were the leading causes of underlying chronic liver disease associated with hepatocellular carcinoma. The results show a trend of increasing incidence of hepatocellular carcinoma; however, the proportion of untreated patients remained constant over the analyzed period. Contexto Estudos sobre epidemiologia do carcinoma hepatocelular e terapias utilizadas em seu tratamento são escassos no Brasil. O objetivo foi caracterizar o carcinoma hepatocelular quanto à etiologia da hepatopatia crônica subjacente e modalidades terapêuticas empregadas, em um centro de referência no Brasil. Método Todos os casos de carcinoma hepatocelular registrados no Departamento de Patologia em período de 12 anos (1998-2010) foram incluídos. Dados demográficos, etiologia da hepatopatia crônica e tipo de tratamento realizado foram coletados dos prontuários. Resultado Esta série de casos incluiu 215 pacientes, com média de idade 57,3 (± 14,1) anos, 164 (76,2%) do sexo masculino. Infecções virais C e B foram detectadas em 88 (43%) e 47 (23%), respectivamente. Abuso de etanol isoladamente ou associado a outras causas foi identificado em 64 (32%) indivíduos. Esquistossomose foi encontrada em 18 (9%) indivíduos. Transplante hepático foi o tratamento de escolha em 112 (51%) pacientes. Esse procedimento foi mais frequentemente realizado em carcinoma hepatocelular relacionado com hepatite C (70%) do que hepatite B (17%). Ressecção cirúrgica foi realizada em 40 (18%) indivíduos, alcoolização ou termo-ablação em 18 (14%) e quimioembolização em 14 (7%). Em 40 (19,4%) pacientes nenhum tratamento foi empregado e esta porcentagem permaneceu constante ao longo dos anos do estudo. Conclusões Hepatite viral C seguida de abuso de etanol e hepatite viral B foram as causas de hepatopatia crônica mais frequentemente associadas ao carcinoma hepatocelular. Os resultados mostram tendência a aumento da incidência do carcinoma hepatocelular; no entanto, a proporção de pacientes não-tratados permaneceu constante ao longo dos anos analisados.
