Schistosomiasis is a highly prevalent disease with >200 million infected people. Pulmonary hypertension one of the pulmonary manifestations in this disease, particularly its hepatosplenic presentation. The aim study was to determine prevalence schistosomiasis patients form disease.All followed up at gastroenterology department our university hospital underwent echocardiographic evaluation search for hypertension. Patients presenting systolic artery pressure >40 mm Hg were further evaluated...
Despite recent advances in treatment of viral hepatitis, liver-related mortality is high, possibly owing to the large burden advanced alcohol-related liver disease (ALD). We investigated whether patients with ALD are initially seen at later stages development than hepatitis C virus (HCV) infection or other etiologies.We performed a cross-sectional study 3453 consecutive either early (1699 and 1754 disease) 17 tertiary care gastrointestinal units worldwide, from August 2015 through March...
Hospitalized patients with cirrhosis frequently undergo multiple procedures. The risk of procedural-related bleeding remains unclear, and management is not standardized. We conducted an international, prospective, multicenter study hospitalized undergoing nonsurgical procedures to establish the incidence identify factors.
OBJECTIVES: Susceptibility to autoimmune hepatitis (AIH) type 1 has been associated with DRB1*03, DRB1*04, and DRB3 alleles in European North-American whites, DRB1*04 Japan, DRB1*13 Latin America. Very few studies have performed on AIH 2. The aim of the present study was evaluate association types 2 HLA-DR DQ loci. METHODS: We HLA-DRB -DQB1 typing by polymerase chain reaction amplification sequence-specific primers (PCR-SSP) 139 patients. Most had circulating anti-smooth muscle antibody...

Background and aim. The lack of information about hepatocellular carcinoma (HCC) in Brazil weakens health policy preventing deaths from the illness. aim this study was to establish cumulative incidence risk factors for development patients under a surveillance program. Material methods. 884 with compensated cirrhosis were prospectively followed up at least five years, August 1998 until 2008, one annual ultrasonography liver examination serum alpha fetoprotein (AFP) measurement. Results....
Background & AimsGenetic ancestry or racial differences in health outcomes exist diseases associated with systemic inflammation (eg, COVID-19). This study aimed to investigate the association of genetic and race acute-on-chronic liver failure (ACLF), which is characterized by acute inflammation, multi-organ failure, high risk short-term death.MethodsThis prospective cohort analyzed a comprehensive set data, including among several others, 1274 patients acutely decompensated cirrhosis who...
Over 1700 liver transplantations (LTs) are performed annually in Brazil. In absolute terms, the country performs more LT surgeries than anywhere else Latin America and is third worldwide. However, due to its increasing population inadequate donor organ supply, averages 5-10 LTs per million population, far lower required. There a marked heterogeneity donation activity throughout country. Access underprivileged North, Midwest, Northeast regions of Brazil scarce. Major challenges for future...
Background Concurrent autoimmune disorders (CAIDs) have been shown to occur in 22% 34% of the patients with hepatitis (AIH). Their presence has linked female gender, older age, and certain HLA antigens, namely HLA-A11, DRB1*04, DRB4*01. Aims To assess frequency nature CAID Brazilian AIH types 1 (AIH-1) 2 (AIH-2) investigate influence genetic background their occurrence. Patients Methods The was studied 143 [117 females, median age 11 (1.3 69)] AIH-1 (n=125) AIH-2 (n=28). typing tumor...
Heart failure (HF) is, after cirrhosis, the second-most common cause of ascites. Serum B-type natriuretic peptide (BNP) plays an important role in diagnosis HF. Therefore, we hypothesized that BNP would be useful differential Consecutive patients with new onset ascites were prospectively enrolled this cross-sectional study. All had measurements serum-ascites albumin gradient (SAAG), total protein concentration ascitic fluid, serum, and BNP. We 218 consecutive resulting from HF (n = 44),...
Background The aims of this study were to analyze the overall survival patients with cirrhosis and small hepatocellular carcinoma (HCC) identify independent pretreatment predictors in Brazil. Methods Between 1998 2003, 74 HCC evaluated. Predictors identified using Kaplan-Meier curves Cox model. Results rates 80%, 41%, 17% at 12, 36, 60 months, respectively. mean length follow-up after diagnosis was 23 months (median 22 mo, range: 1 86 mo) for entire group. Univariate analysis showed that...
Background and aims Quantifying systemic inflammation (SI) in acutely decompensated cirrhosis (ADC) is of major importance because SI a driver the most severe forms ADC, including acute-on-chronic liver failure (ACLF). Blood biomarkers already evaluated ADC failed to appropriately assess ADC. We aimed investigate whether gene expression related circulating immune cells could quantify Methods Standard (white cell count, C reactive protein, cytokines) genome-wide RNA (RNA-sequencing) were...
