BACKGROUND: A liver stiffness (LS) < 21 kPa has a high negative predictive value (NPV) to exclude the presence of esophageal varices (EV) at risk of bleeding in HIV/HCV-coinfected patients. Consequently, upper gastrointestinal endoscopy (UGE) for the screening of EV could be avoided in these patients. However, this strategy has not been widely accepted due to concerns about its safety. OBJECTIVE: To assess the ability of LS to predict the risk of portal hypertensive gastrointestinal bleeding (PHGB) in HIV/HCV-coinfected patients with compensated cirrhosis...

Purpose Criminalization of drug use in Malaysia has concentrated people who inject drugs (PWID) and people living with HIV into prisons where health services are minimal and HIV-related mortality is high. Few studies have comprehensively assessed the complex health needs of this population. The paper aims to discuss these issues. Design/methodology/approach From October 2012 through March 2013, 221 sequentially selected HIV-infected male prisoners underwent a comprehensive health assessment that included a structured history, physical examination, and clinically indicated diagnostic studies...

Two billion people have been exposed to HBV and exhibit serological markers of past infection such as anti-HBc and/or anti-HBs. However, around 240 million suffer from chronic hepatitis B, as defined by the presence of serum HBsAg for longer than six months. In addition, a small proportion of patients exposed to HBV may harbor detectable viremia (serum HBV DNA) in the absence of HBsAg, which is named "occult hepatitis B".

Data on markers of hepatitis C virus (HCV) disease in HIV-HCV-coinfected patients in resource-limited settings are scarce. We assessed HCV RNA, HCV genotype (GT), IL28B GT and liver fibrosis (FibroScan(®) ) in 480 HIV-infected patients with positive HCV antibody in four HIV treatment centres in South-East Asia. We enrolled 165 (34.4%) patients in Jakarta, 158 (32.9%) in Bangkok, 110 (22.9%) in Hanoi and 47 (9.8%) in Kuala Lumpur. Overall, 426 (88.8%) were male, the median (IQR) age was 38.1 (34.7-42.5) years, 365 (76...

Hepatitis C virus (HCV) mainly targets the liver but can also induce extrahepatic manifestations. The kidney may be impacted via an immune mediated mechanism or a cytopathic effect. HCV patients are clearly at a greater risk of chronic kidney disease (CKD) than uninfected patients are, and the presence of CKD increases mortality. Interferon-based therapies and ribavirin are difficult to manage and are poorly effective in end-stage renal disease and hemodialysis. These patients should be given priority treatment with new direct anti-viral agents (DAAs) while avoiding peginterferon and ribavirin...

BACKGROUND: HIV infection is independently associated with risk of lung cancer, but few data exist for the relation between longitudinal measurements of immune function and lung-cancer risk in people living with HIV. METHODS: We followed up participants with HIV from the Veterans Aging Cohort Study for a minimum of 3 years between Jan 1, 1998, and Dec 31, 2012, and used cancer registry data to identify incident cases of lung cancer. The index date for each patient was the later of the date HIV care began or Jan 1, 1998...

BACKGROUND: We examined discharges for infective endocarditis (IE) at an academic teaching hospital for over 10 years to evaluate if an increase in hospitalizations for IE and increase in hepatitis C virus (HCV) in patients with IE could predict a new epidemic of injection drug use (IDU). MATERIALS AND METHODS: Retrospective medical record review of discharged patients with the diagnosis of IE as defined by the modified Duke criteria. Student's t test, chi-squared test and Fisher's exact test were used to calculate P values...

BACKGROUND: Hepatitis C virus (HCV) and HIV are both transmitted through percutaneous exposures among people who inject drugs (PWID). Ecological analyses on global epidemiological data have identified a positive association between HCV and HIV prevalence among PWID. Our objective was to demonstrate how HCV prevalence can be used to predict HIV epidemic potential among PWID. METHODS: Two population-level models were constructed to simulate the evolution of HCV and HIV epidemics among PWID...

BACKGROUND: Persons who inject drugs (PWID) are at increased risk for poor health outcomes and bloodborne infections, including human immunodeficiency virus (HIV), hepatitis C virus and hepatitis B virus infections. Although substantial progress has been made in reducing HIV infections among PWID, recent changes in drug use could challenge this success. METHODS: CDC used National HIV Surveillance System data to analyze trends in HIV diagnoses. Further, National HIV Behavioral Surveillance interviews of PWID in 22 cities were analyzed to describe risk behaviors and use of prevention services among all PWID and among PWID who first injected drugs during the 5 years before their interview (new PWID)...

BACKGROUND: Human immunodeficiency virus (HIV) and hepatitis B virus (HBV) coinfection has been associated with higher morbidity and mortality and may impact significantly on healthcare resource utilization. However, in Ghana, accurate estimates of the prevalence of HIV/HBV coinfection needed to inform policy decisions and the design of public health interventions are currently lacking. In this study, our aim was to determine the HIV/HBV coinfection prevalence rate in Ghana. METHODS: Primary studies reporting prevalence of HIV/HBV coinfection in Ghana were retrieved through searches conducted in PubMed, science direct, Google scholar and Africa journals online (AJOL) databases...

OBJECTIVE: Very-low-level viremia (VLLV) is a relatively new concept in the realm of human immunodeficiency virus (HIV) care. Newer generation assays are now able to detect plasma HIV RNA Viral Load (VL) levels as low as 20 copies/mL. The authors characterized patients with VLLV (VL between 20 and 50 copies/mL) in order to identify possible risk factors associated with virologic failure and poor clinical outcomes. METHODS: The authors reviewed 119 consecutive charts of patients with VLLV...

Cis-acting RNA structural elements govern crucial aspects of viral gene expression. How these structures and other post-transcriptional signals affect RNA trafficking and translation in the context of single cells is poorly understood. Herein we describe a multi-color, long-term (>24 h) imaging strategy for measuring integrated aspects of viral RNA regulatory control in individual cells. We apply this strategy to demonstrate differential mRNA trafficking behaviors governed by RNA elements derived from three retroviruses (HIV-1, murine leukemia virus, and Mason-Pfizer monkey virus), two hepadnaviruses (hepatitis B virus and woodchuck hepatitis virus) and an intron-retaining transcript encoded by the cellular NXF1 gene...

Hepatitis C virus (HCV) readily establishes chronic infection, which is characterized by failure of virus-specific CD8+ T cells. HCV uses epitope mutation and T-cell exhaustion to escape from the host immune response. Previously, we engineered high-affinity T-cell receptors (HATs) targeting HIV escape mutants. In this study, the affinity of a T-cell receptor specific for the human leukocyte antigen (HLA)-A2-restricted HCV immunodominant epitope NS3 1406-1415 (KLVALGINAV) was improved from a KD of 6.6 µM to 40 pM...
