Background.: Historically, acute hepatitis C virus (HCV) infection was treated with shorter durations of interferon-containing therapies. In the era of direct-acting antivirals (DAAs), it is unclear whether the efficacy of treatment achieved in chronic infection can be maintained with abbreviated courses of therapy during the acute phase. Methods.: The sofosbuvir-containing regimens without interferon for treatment of acute HCV in HIV-1 infected individuals (SWIFT-C) is an open-label, 2-cohort clinical trial in which the first cohort assessed for the safety and efficacy of 12 weeks of sofosbuvir plus ribavirin for the treatment of acute HCV infection in participants with chronic human immunodeficiency virus type 1 (HIV-1) infection...

BACKGROUND: Cancer is a growing problem in persons living with HIV infection (PLWH) and hepatitis C virus (HCV) coinfection could play an additional role in carcinogenesis. Herein, all cancers in an HIV-mono and HIV/HCV-coinfected cohort were evaluated and compared to identify any differences between these two populations. METHODS: A retrospective cohort study was conducted including all cancers in PLWH between 1993 and 2014. Cancers were classified in two groups, AIDS-defining cancer (ADC) and non AIDS-defining cancer (NADC)...

OBJECTIVES: Despite the high burden of hepatitis C virus (HCV)-related morbidity and mortality among HIV-positive people who use illicit drugs (PWUD), uptake of interferon-based treatments for HCV infection has been negligible among this group. Direct-acting antiviral (DAA) therapies offer an opportunity to expand treatment access among this population. The aim of this study was to explore willingness to use DAA-based regimens among HIV/HCV-coinfected PWUD in Vancouver, Canada. METHODS: Data were drawn from the AIDS Care Cohort to evaluate Exposure to Survival Services (ACCESS), a prospective cohort of HIV-positive PWUD...

BACKGROUND: Patients with liver metastatic colorectal cancer (mCRC) often benefit from receiving (90)Y-microsphere radioembolization (RE) administered via the hepatic arteries. Prior to delivery of liver-directed radiation, standard laboratory tests may assist in improving outcome by identifying correctable pre-radiation abnormalities. METHODS: A database containing retrospective review of consecutively treated patients of mCRC from July 2002 to December 2011 at 11 US institutions was used...

BACKGROUND: Treatment for chronic hepatitis C virus (HCV) infection has rapidly evolved into interferon-free directly acting antiviral regimens (DAA) that result in high sustained-virologic-response. DAAs primarily work by suppressing HCV replication and rely less on the immune system than interferon-based therapies. However it is unclear whether the immune system recovers with suppression of HCV replication and contributes to HCV clearance with DAA therapy. We previously demonstrated HCV clearance is associated with increased HCV-specific-immunity in CHCV-GT-1 infected patients during treatment with sofosbuvir (SOF)+ribavirin (RBV)...

Methadone is a cornerstone therapy for opioid addiction and a public health strategy for HIV/AIDS and hepatitis C reduction. Methadone is also used for acute and chronic pain. As use for chronic pain has grown, so too have adverse events. Constitutive and acquired (drug interactions) inter- and intraindividual variability in methadone pharmacokinetics and pharmacodynamics confounds reliable clinical use. Identification of enzymes and transporters responsible for methadone disposition has been a long-sought ideal...

The literature on adrenal gland tumour in HIV-infected patients is scarce. We report a 46-year-old Malay man with HIV and Hepatitis C infection presenting with a large nonfunctioning adrenal tumour. Computed tomography showed a large right adrenal tumour with heterogeneous enhancement and central necrosis. A high index of suspicion of a malignant tumour or pheochromocytoma led us to surgical removal of the adrenal gland. In this case report, we highlight important features to look for during pre-op evaluation of a large adrenal mass...

Viral hepatitis B (HBV) and hepatitis C (HCV) pose a major health problem globally and if untreated, both viruses lead to severe liver damage resulting in liver cirrhosis and cancer. While HBV has a vaccine, HCV has none at the moment. The risk of drug resistance, combined with the high cost of current therapies, makes it a necessity for cost-effective therapeutics to be discovered and developed. The recent surge in interest in Medical Cannabis has led to interest in evaluating and validating the therapeutic potentials of Cannabis and its metabolites against various diseases including viruses...

Hepatitis C virus (HCV) is a major cause of end-stage liver diseases. With 3-4 million new HCV infections yearly, a vaccine is urgently needed. A better understanding of virus escape from neutralizing antibodies and their corresponding epitopes are important for this effort. However, for viral isolates with high antibody resistance, or antibodies with moderate potency, it remains challenging to induce escape mutations in vitro. Here, as proof-of-concept, we used antibody-sensitive HVR1-deleted (ΔHVR1) viruses to generate escape mutants for a human monoclonal antibody, AR5A, targeting a rare cross-genotype conserved epitope...

OBJECTIVES: Two nucleos(t)ide reverse-transcriptase inhibitors (NRTIs) plus 1 non-NRTI (nNRTI) remain the preferred or alternative combination antiretroviral therapy (cART) for antiretroviral-naive HIV-positive patients in Taiwan. The three most commonly used nNRTIs are nevirapine (NVP), efavirenz (EFV) and rilpivirine (RPV). This study aimed to determine the incidences of hepatotoxicity and skin rashes within 4 weeks of initiation of cART containing 1 nNRTI plus 2 NRTIs. METHODS: Between June, 2012 and November, 2015, all antiretroviral-naive HIV-positive adult patients initiating nNRTI-containing cART at 8 designated hospitals for HIV care were included in this retrospective observational study...

BACKGROUND: All recent treatment guidelines recommend integrase strand transfer inhibitors (INSTIs) as components of initial HIV therapy. Bictegravir, a novel, once-daily, unboosted INSTI, showed potent activity in a 10 day monotherapy study and has a high in-vitro resistance barrier. On the basis of these results, we did a phase 2 trial comparing bictegravir with dolutegravir. METHODS: In this randomised, double-blind, phase 2 trial, we recruited previously untreated adults (aged ≥18 years) with HIV-1 infections from 22 outpatient centres in the USA...

Despite the recent success of newly developed direct acting antivirals against Hepatitis C, the disease continues to be a global health threat due to lack of diagnosis of most carriers and the high cost of treatment. The heterodimer formed by the glycoproteins E1 and E2 within the hepatitis C virus (HCV) lipid envelope is a potential vaccine candidate and antiviral target. While the structure of E1/E2 has not yet been resolved, partial crystal structures of the E1 and E2 ectodomains have been determined. The unresolved parts of the structure are within the realm of what can be modeled with current computational modeling tools...
