Methods: This prospective cohort study analyzed a comprehensive set of data, including genetic ancestry and race among several others, in 1274 patients with acutely decompensated cirrhosis who were nonelectively admitted to 44 hospitals from 7 Latin American countries.

Hepatic epithelioid hemangioendothelioma: how fast does it grow and which findings could have prevented diagnostic delay?-a case report.

Background: Hepatic epithelioid hemangioendothelioma (HEHE) is a rare neoplastic disease of varied presentation and unspecific radiological signs in the early stages. The diagnostic delay can lead to metastatic disease, thus increasing the tumor burden and reducing the treatment options. HEHE is usually deemed a slow-growing tumor, but its speed of growth is poorly reported and still unknown.

National Brazilian survey on the outcomes of hepatitis c retreatment in patients non-responders to direct antiviral agents.

Background And Aims: Treatment of hepatitis C with direct antiviral agents (DAA) is associated with almost 95% of sustained virological response. However, some patients need retreatment. In Brazil, it should be done according to the Ministry of Health guidelines, frequently updated to include newly available drugs.

HLA-DRB1 Polymorphisms and Rheumatologic Manifestations in Chronic Hepatitis C.

Background/aims: Hepatitis C has been associated with rheumatologic manifestations (HCV-related RM). Clinically, HCV-related RM may be indistinguishable from the symptoms that occur in diffuse connective tissue diseases (DCTD-related RM), making the differential diagnosis difficult. Host genetic factors, such as the Human Leukocyte Antigens (HLA) polymorphisms were associated with HCV infection, however, there are no studies that discriminate between HCVrelated RM and DCTD-related RM.

Initially, 540 publications were found and, after applying the study inclusion criteria, 22 articles were selected.

Cirrhosis regression after SVR with indirect methods of fibrosis analysis: How far is it real?

Hepatitis C virus has infected over 71 million people worldwide, and it is the main cause of cirrhosis in the western world. Currently, the treatment involves direct-acting antiviral agents (DAAs) and its main goal is to achieve sustained virologic response (SVR). The aim of this study was to evaluate the impact of SVR using DAAs in the improvement of liver fibrosis using scores evaluation by indirect method, liver function, and inflammation indirect biomarkers.

Inflammation response and liver stiffness: predictive model of regression of hepatic stiffness after sustained virological response in cirrhotics patients with chronic hepatitis C.

Cirrhotic patients with chronic hepatitis C should be monitored for the evaluation of liver function and screening of hepatocellular carcinoma even after sustained virological response (SVR). The stage of inflammatory resolution and regression of fibrosis is likely to happen, once treatment and viral clearance are achieved. However, liver examinations by elastography show that 30-40% of patients do not exhibit a reduction of liver stiffness.

New LncRNAs in Chronic Hepatitis C progression: from fibrosis to hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related death in the world, and about 80% of the cases are associated with hepatitis B or C. Genetic and epigenetic alterations are accumulated over decades of chronic injury and may affect the functioning of tumor suppressor genes and protooncogenes. Studies have evidenced the role of Long non-coding RNAs (LncRNA) with oncogenic or tumor suppressor activities, suggesting a great potential in the treatment, diagnosis or indicator of prognosis in cancer.

Human platelet antigen-3 polymorphism as a risk factor for rheumatological manifestations in hepatitis C.

Introduction: Hepatitis C virus (HCV) infection is involved in the pathogenesis of autoimmune and rheumatic disorders. Although the human platelet antigens (HPA) polymorphism are associated with HCV persistence, they have not been investigated in rheumatological manifestations (RM). This study focused on verifying associations between allele and genotype HPA and RM in patients with chronic hepatitis C.

Safety and efficacy of risedronate for patients with esophageal varices and liver cirrhosis: a non-randomized clinical trial.

Despite the high prevalence of osteoporosis in liver cirrhosis, the indication of bisphosphonates for patients with esophageal varices has been avoided due to risk of digestive mucosal damage. Therefore, this study aimed to evaluate the safety profile of risedronate treatment for patients with osteoporosis, liver cirrhosis and esophageal varices with low risk of bleeding. A total of 120 patients were allocated into two groups according to their bone mineral density measured by dual-energy X-ray absorptiometry.

A novel molecular mechanism to explain mutations of the HCV protease associated with resistance against covalently bound inhibitors.

NS3 is an important therapeutic target for direct-acting antiviral (DAA) drugs. However, many patients treated with DAAs have unsustained virologic response (UVR) due to the high mutation rate of HCV. The aim of this work was to shed some light on the puzzling molecular mechanisms of the virus's of patients who showed high viral loads even under treatment with DAA.
