OBJECTIVE: Birth diagnosis of HIV-1 infection offers an ideal opportunity for early antiretroviral treatment (ART) to limit HIV-1 reservoir size and limit disease progression. Although data on cellular HIV-1 DNA decay exist for children commencing treatment from 2-3 months of age, data is lacking for starting shortly after birth. DESIGN: We studied infants who initiated ART within 8 days after birth to assess HIV-1 DNA levels longitudinally. METHODS: Children were recruited from public health clinics in Cape Town where birth diagnosis of HIV-1 coupled with early ART initiation occurred...

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...

PURPOSE: The Comparative Outcomes And Service Utilization Trends (COAST) Study in British Columbia (BC), Canada, was designed to evaluate the determinants of health outcomes and health care services use among people living with HIV (PLHIV) as they age in the period following the introduction of combination antiretroviral therapy (cART). The study also assesses how age-associated comorbidities and health care use among PLHIV may differ from those observed in the general population. PARTICIPANTS: COAST was established through a data linkage between two provincial data sources: The BC Centre for Excellence in HIV/AIDS Drug Treatment Program, which centrally manages cART dispensation across BC and contains prospectively collected data on demographic, immunological, virological, cART use and other clinical information for all known PLHIV in BC; and Population Data BC, a provincial data repository that holds individual event-level, longitudinal data for all 4...

In order to optimally refine the multiple emerging drug targets for hepatitis B virus (HBV), it is vital to evaluate virological and immunological changes at the site of infection. Traditionally liver biopsy has been the mainstay of HBV disease assessment, but with the emergence of non-invasive markers of liver fibrosis, there has been a move away from tissue sampling. Here we argue that liver biopsy remains an important tool, not only for the clinical assessment of HBV but also for research progress and evaluation of novel agents...

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)...

Background: The 1918 Spanish H1N1 influenza pandemic was the most severe recorded influenza pandemic with an estimated 20-50 million deaths worldwide. Even though it is known that influenza viruses can cause extra-respiratory tract complications-which are often severe or even fatal- the potential contribution of extra-respiratory tissues to the pathogenesis of 1918 H1N1 virus infection has not been studied comprehensively. Methods: Here, we performed a time course study in ferrets inoculated intranasally with 1918 H1N1 virus, with special emphasis on the involvement of extra-respiratory tissues...

Hepatitis C virus (HCV) infection is increasingly seen as a major public health problem, threat, and concern worldwide. In Yemen about 1.7% of the population is infected with chronic hepatitis C. This study aimed to detect the predictors for response to pegylated interferon and ribavirin (Peg-IFN/RBV) in chronic HCV Yemeni patients. The study was conducted on 100 patients with chronic HCV who received Peg-IFN/RBV in the 48th Military Hospital in Sana'a Yemen, from 2011 to 2013. All patients were subjected to complete history taking, thorough clinical examinations, routine laboratory investigation, and abdominal ultrasonography...

BACKGROUND: Therapy in chronic hepatitis B (CHB) patients aims at improving their survival by preventing disease progression to cirrhosis and its complications. Entecavir (ETV) is currently a first line therapeutic agent recommended for the treatment of CHB. Our aim was to evaluate the long term outcome of a cohort of CHB patients treated with ETV. METHODS: Thirty-four patients treated with ETV for at least 6 months were included in this study. The virologic response was determined by the dosage of serum HBV-DNA, HBsAg, HBeAg, anti-HBs and anti-HBe antibodies...

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...

The Cochrane Collaboration has published a systematic review about the treatment chronic hepatitis C (CHC) with direct-acting antivirals (DAAs) concluding that there is no evidence either to confirm or to reject the premise that DAAs have any clinical effects and they also state that sustained virological response is an unreliable surrogate marker to assess clinical efficacy. Here we discuss the implication of the Cochrane Collaboration review at the light of the current knowledge of CHC clinical management and propose a framework for the future research...

An 18 year old boy attended a dermatology clinic outside our hospital and diagnosed with psoriasis. His skin lesions over both ankles (Fig. 1) did not improve at all with potent local steroids twice for 3 months, then 3 times daily for another 3 months. His dermatologist talked to him about using methotrexate and asked for liver function tests before starting the systemic therapy. His ALT and AST were doubled. The patient came to our Hepatology clinic worried about his elevated liver enzymes. We asked for viral markers...

With the wide use of direct-acting antiviral agents (DAAs), more and more patients with chronic hepatitis C achieve sustained virological response; however, no consensus has been reached on the application of DAAs in the treatment of hepatitis C virus-related hepatocellular carcinoma (HCC). This article summarizes and evaluates related issues in this field, including whether antiviral therapy with DAAs in patients with hepatitis C can increase the incidence or recurrence rate of HCC, as well as whether DAAs can be used for hepatitis C in HCC patients after antitumor treatment and the efficacy of DAAs in such patients...

The APOBEC mutational signature has only recently been detected in a multitude of cancers through next-generation sequencing. In contrast, APOBEC has been a focus of virology research for over a decade. Many lessons learnt regarding APOBEC within virology are likely to be applicable to cancer. In this review, we explore the parallels between the role of APOBEC enzymes in HIV and cancer evolution. We discuss data supporting the role of APOBEC mutagenesis in creating HIV genome heterogeneity, drug resistance, and immune escape variants...

Therapeutic strategies aimed at achieving antiretroviral therapy (ART)-free HIV remission in infected individuals are under active investigation. Considering the vast majority of HIV-infected individuals experience plasma viral rebound upon cessation of therapy, clinical trials evaluating the efficacy of curative strategies would likely require inclusion of ART interruption. However, it is unclear what impact short-term analytical treatment interruption (ATI) and subsequent reinitiation of ART have on immunologic and virologic parameters of HIV-infected individuals...
