OBJECTIVE(S): One in four persons living with HIV is coinfected with HCV. Biological and behavioral mechanisms may increase HIV viral load among coinfected persons. Therefore, we estimated the longitudinal effect of chronic HCV on HIV suppression after ART initiation among women with HIV (WWH). DESIGN: HIV RNA was measured every six months among 441 WWH in the Women's Interagency HIV Study who initiated ART from 2000-2015. METHODS: Log-binomial regression models were used to compare the proportion of study visits with detectable HIV RNA between women with and without chronic HCV...

INTRODUCTION: HIV-1 infection leads to chronic inflammation and to an increased risk of non-AIDS mortality. Our objective was to determine whether AIDS-defining events (ADEs) were associated with increased overall and cause-specific non-AIDS related mortality after antiretroviral therapy (ART) initiation. METHODS: We included HIV treatment-naïve adults from the Antiretroviral Therapy Cohort Collaboration (ART-CC) who initiated ART from 1996 to 2014. Causes of death were assigned using the Coding Causes of Death in HIV (CoDe) protocol...

Hereditary bleeding disorders include a group of diseases with abnormalities of coagulation. Prior to 1990, infection with hepatitis C virus (HCV) was mainly transmitted via pooled plasma products as a treatment for hereditary bleeding disorders. Anti-HCV positivity in these patients may be as high as >70% in some areas, while some of them have also been coinfected with human immunodeficiency virus. Since about 20% of HCV-infected patients clear the infection naturally, chronic HCV infection represents a significant health problem in this group of patients...

BACKGROUND AND AIM: Hepatitis C virus (HCV)-related cirrhosis, one of the most common etiologies of liver cirrhosis in the Western world, is a risk factor for hepatocellular carcinoma. To confirm and improve current effectiveness of screening and prognosis of patients with established cirrhosis, a credible, simple plasma biomarker is needed. Hepatic stellate cell activation, a pivotal event in cirrhosis development, results in increased secretion of extracellular matrix proteins, including tenascin-C (TnC)...

IFNL3 is the strongest predictor of spontaneous resolution (SR) of hepatitis C virus (HCV), however, consideration of IFNL3 genotype alone is of limited clinical value for the prediction of SR or chronic HCV infection. The objective of this study was to analyze the impact of HLA-B, HLA-C and KIRs on SR, as well as their additive effects on the predictive value of the IFNL3 genotype. We conducted a retrospective study of HIV patients that included both SR and chronic HCV patients. In our study, 61.6% of patients with IFNL3 CC achieved SR, and 81...

Fatal clostridial infections and clostridial toxicoses are common in birds. Most fatalities are associated with toxin production and progress rapidly, often within 24 hours of infection. We describe an unusual and protracted course of disease in 6 captive brown pelicans ( Pelecanus occidentalis), which was believed to result from toxicosis by toxovar A produced by a mixed infection with Clostridium sordellii and Clostridium perfringens. Although the first death in the group occurred 3 days after signs of illness were documented, the remaining birds died over a 38-day period despite aggressive antibiotic and supportive therapy...

Hepatitis C virus (HCV) infection affects many organs in the body, including the liver, kidneys, skin, joints and others. Although the hepatic manifestation of HCV has been widely studied, the extrahepatic manifestaions of HCV have not been fully appreciated. Studies have shown that patients with HCV have a higher risk of chronic kidney disease and end-stage renal disease, as well as poorer outcomes after kidney transplantation. Given these findings, it is important to screen HCV patients for presence of renal impairement in a timely manner...

BACKGROUND: Direct-acting antiviral (DAA) regimens have shown high efficacy and tolerability for patients with HCV genotype 1/1b (GT1/1b) in clinical trials. However, robust real-world evidence of interferon (IFN)-free DAA treatment for HCV GT1-infected patients in Asia is still lacking. AIM: To systematically review and meta-analyse the effectiveness and tolerability of IFN-free DAA therapy for HCV GT1 infection in Asia. METHODS: We included studies that enrolled adult patients with HCV GT1 infection in routine clinical practice in Asia, using IFN-free DAA regimens, and reported sustained virological response (SVR) after 12/24 weeks end-of-treatment by 31 May 2017...

Hepatitis C virus (HCV) is a worldwide threaten to human health with a high ratio of chronic infections. Recently, we found that Vpr-mediated regulation of HCV replication depends on the host protein DDB1-Cul4 associate factor 1 (DCAF1), implying that DCAF1 might be involved in the replication of HCV. In this study, we demonstrated that DCAF1 knockdown reduced HCV replication both in the infectious (JFH1) and replicon (Con1) systems. Further investigation showed a negative regulation of HCV internal ribosome entry site (IRES)-mediated translation by DCAF1...

Lichen planus is an inflammatory dermatosis with a prevalence of approximately 1%. Recent meta-analyses show that patients with hepatitis C virus have a 2.5- to 4.5-fold increased risk of developing lichen planus. Lichen planus has also followed vaccinations and has specifically been attributed to the hepatitis B vaccine, the influenza vaccine, and the tetanus-diphtheria-acellular pertussis vaccine. We describe a case of lichen planus in a hepatitis C virus-infected African American male occurring in temporal association with the administration of the tetanus-diphtheria-acellular pertussis vaccine...
