14. Prevalence and trends in transfusion-transmissible infections among blood donors in Brazil from 2010 to 2016
ABSTRACT Background: Assessing trends in the rate of transfusion-transmissible infections (TTIs) in blood donors is critical to the monitoring of the blood supply safety and the donor screening effectiveness. The objective of this study was to conduct a trend analysis of TTIs and associated demographic factors of donors at a public blood bank in the central

15. Seroprevalence of transfusion-transmissible infectious diseases at a hemotherapy service located in southwest Bahia, Brazil
ABSTRACT Introduction: The serological screening of blood donors has been instituted by the Brazilian Ministry of Health and is mandatory in the research on several diseases transmissible through blood transfusion. Blood banks need to establish a screening service capable of reducing associated transfusions risks. Objective: The objective of this study was

16. Coexistence of low levels of HBsAg and high levels of anti-HBs may increase risk of hepatocellular carcinoma in chronic hepatitis B patients with high HBV load
ABSTRACT Objective: The clinical significance of coexistence of HBsAg/anti-HBs in chronic hepatitis B (CHB) patients remains controversial. This study was aimed to assess the association of this serological pattern with hepatocellular carcinoma (HCC) in patients with CHB. Methods: In this cross-section study, 206 CHB patients with coexistence of HBsAg/anti

18. Hepatitis C prevalence among men who have sex with men in Central Brazil
Abstract To assess the prevalence of hepatitis C virus infection among men who have sex with men (MSM) in Central Brazil, a cross-sectional study was conducted in the City of Goiânia, Central Brazil, using Respondent-Driven Sampling (RDS). All serum samples were tested for anti-HCV and also for alanine aminotransferase (ALT). Anti-HCV positive samples and/o

19. [PROVISIONAL] Resistance mutations of NS3 and NS5b in treatment-naïve patients infected with Hepatitis C virus in Santa Catarina and Rio Grande do Sul States, Brazil
Abstract Hepatitis C virus (HCV) infection is a worldwide health problem. Nowadays, direct-acting antiviral agents (DAAs) are the main treatment; however, the high level of variability of HCV lead to development of resistance-associated variants (RAVs). Thus, look into the RAVs among infected patients is an important tool for monitoring the efficacy of the t

20. Necrolytic acral erythema in a Chinese patient with hepatitis C and hepatitis B virus coinfection
Abstract: Necrolytic acral erythema is a distinct erythema that has been described as an extrahepatic manifestation of hepatitis C virus infection. Most reported cases have been in Africa, especially Egypt. We report the first case (to the best of our knowledge) of necrolytic acral erythema in a Chinese patient with HCV and HBV coinfection. We aim to increas

21. Hepatitis B virus infection among oncohematologic disease patients in Central Brazil: prevalence, risk factors and immunization
ABSTRACT Introduction: Carriers of oncohematological diseases are at high risk for hepatitis B virus (HBV) infection. Objective and method: To investigate the epidemiology of HBV infection in Goiânia, Central Brazil, 322 individuals with oncohematological diseases (leukemias, Hodgkin lymphoma and non-Hodgkin lymphoma) were interviewed and blood samples we

22. Influence of antiretroviral therapy on bone metabolism of patients with chronic hepatitis B: a review
Abstract Hepatitis B is a major public health problem worldwide and associated with significant mortality. To prevent or delay the deleterious effects of chronic infection by the hepatitis B virus, patients should be carefully followed, and antiviral therapy indicated according to specific recommendations. Currently, available drugs inhibit viral replication

23. Serum regucalcin is a useful indicator of liver injury severity in patients with hepatitis B virus-related liver diseases
Regucalcin is a soluble protein that is principally expressed in hepatocytes. Studies of regucalcin have mainly been conducted in animals due to a lack of commercially available kits. We aimed to develop an enzyme-linked immunosorbent assay (ELISA) to quantify serum regucalcin in patients with hepatitis B virus (HBV)-related disease. High-titer monoclonal an
