Anti-E1E2 antibodies status prior therapy favors direct-acting antiviral treatment efficacy.

INTRODUCTION: Presence of anti-E1E2 antibodies was previously associated with spontaneous cure of hepatitis C virus (HCV) and predictive before treatment of a sustained virological response (SVR) to bi- or tri-therapy in naïve or experienced patients, regardless of HCV genotype. We investigated the impact of anti-E1E2 seroprevalence at baseline on treatment response in patients receiving direct-acting antiviral (DAA) therapy. MATERIAL AND METHODS: We screened anti-E1E2 antibodies by ELISA in serum samples collected at treatment initiation for two groups of patients: 59 with SVR at the end of

'Real-life' experience with direct-acting antiviral agents for hepatitis C virus in end-stage renal disease.

BACKGROUND AND AIMS: The advent of direct-acting antiviral agents promises to change the management of hepatitis C in patients with end-stage renal disease, a patient group where the treatment of hepatitis C was historically challenging. We investigated the safety and efficacy of all-oral, interferon-free direct-acting antiviral agents for the treatment of hepatitis C in a 'real-world' group of patients with end-stage renal disease. METHODS: We performed a single-arm, multi-centre study in a cohort (n=30) of patients with advanced chronic kidney disease (mostly on dialysis) who underwent anti

Inhibition of monoacylglycerol lipase, an anti-inflammatory and antifibrogenic strategy in the liver.

OBJECTIVE: Sustained inflammation originating from macrophages is a driving force of fibrosis progression and resolution. Monoacylglycerol lipase (MAGL) is the rate-limiting enzyme in the degradation of monoacylglycerols. It is a proinflammatory enzyme that metabolises 2-arachidonoylglycerol, an endocannabinoid receptor ligand, into arachidonic acid. Here, we investigated the impact of MAGL on inflammation and fibrosis during chronic liver injury. DESIGN: C57BL/6J mice and mice with global invalidation of MAGL (MAGL -/- ), or myeloid-specific deletion of either MAGL (MAGLMye-/-), ATG5 (ATGMye

Kv7 channels in the nucleus accumbens are altered by chronic drinking and are targets for reducing alcohol consumption.

Alcohol use disorders (AUDs) are a major public health issue and produce enormous societal and economic burdens. Current Food and Drug Administration (FDA)-approved pharmacotherapies for treating AUDs suffer from deleterious side effects and are only effective in a subset of individuals. It is therefore essential to find improved medications for the management of AUDs. Emerging evidence suggests that anticonvulsants are a promising class of drugs for treating individuals with AUDs. In these studies, we used integrative functional genomics to demonstrate that genes that encode Kv7 channels (i.e

Therapeutic amprenavir concentrations in cerebrospinal fluid.

Antiretrovirals that reach higher concentrations in cerebrospinal fluid (CSF) are associated with better control of HIV in CSF and possibly better neurocognitive performance. The objective of this study was to determine whether amprenavir (APV) concentrations in CSF are in the therapeutic range. Individuals were selected based on the use of regimens that included fosamprenavir (FPV), a prodrug of APV, and the availability of stored CSF and matched plasma. Total APV was measured in 119 matched CSF-plasma pairs from 75 subjects by high-performance liquid chromatography (HPLC) (plasma) or liquid

Is a Good Sleep on Mosquito-Free Nights Worth the Risk of Lymphoma Associated with the Use of Household Insecticides? A Case-Control Study of Lymphoma Subtypes in Adults.

BackgroundThe evidence linking the use of household pesticides and the risk of lymphoma is scanty.MethodsWe explored the hypothesis in a population-based case-control study on lymphoma conducted in Sardinia, Italy, in 1998-2004, including 325 cases and 465 population controls and data on lifetime frequency, seasonality, and years of use of household insecticides and potential confounders. We calculated the risk of lymphoma (all subtypes) and its major subtypes associated with using household insecticides in three time windows (up to 1978, from 1979-2001, and 2002 onwards) with unconditional lo

Building resilience against the growing threat of arboviruses: a scoping review of Aedes vector surveillance, control strategies and insecticide resistance in Africa.

BACKGROUND: The number of reports of arboviral outbreaks is increasing and, consequently, the need for effective surveillance and vector control plans for Aedes-borne diseases is becoming more urgent. To explore the current state of knowledge of Aedes arbovirus vectors in Africa, we reviewed studies published between 1980 and 2023 that involved Aedes vector surveillance, vector control or insecticide resistance, with the aim to synthesize information and identify knowledge gaps to guide future Aedes research and control in Africa. METHODS: Studies conducted in Africa and published between 198

Direct Antivirals Can Achieve a Cure in All Patients With Chronic Hepatitis C due to Genotype 5: A French Multicentre Study.

BACKGROUND: Hepatitis C virus genotype 5 (HCV-GT-5) is found mainly in South Africa. In our area in central France, the prevalence of HCV-GT-5 is 14%. METHODS AND RESULTS: Here we evaluated sustained virological response at week 12 post-treatment (SVR12) in 147 HCV-GT-5 patients from 14 French university hospitals (2014-2021) treated with direct-acting antivirals (DAA) in real-life. Patients had mainly received sofosbuvir/ledipasvir ± ribavirin, sofosbuvir/velpatasvir, and glecaprevir/pibrentasvir. Overall SVR12 was 98% (144/147). Two patients experienced relapse: one was successfully retreat

Real-life effectiveness of sofosbuvir/velpatasvir/voxilaprevir in hepatitis C patients previously treated with sofosbuvir/velpatasvir or glecaprevir/pibrentasvir.

BACKGROUND: Sofosbuvir, velpatasvir and voxilaprevir (SOF/VEL/VOX) is the recommended rescue therapy for patients with chronic hepatitis C infection who fail direct-acting antivirals (DAAs). Data are limited on the effectiveness of this treatment after the current first-line therapies. Our aim was to analyse the effectiveness and safety of SOF/VEL/VOX among patients failing sofosbuvir/velpatasvir (SOF/VEL) or glecaprevir/pibrentasvir (GLE/PIB). METHODS: Retrospective multicentre study (26 Spanish hospitals), including chronic hepatitis C patients unsuccessfully treated with SOF/VEL or GLE/PIB

Incidence and predictors for abnormal liver function during direct-acting antiviral agents in chronic hepatitis C patients.

Abrupt alanine aminotransferase (ALT) elevation during direct-acting antiviral agents (DAA) treatment is an uncommon but noticeable adverse event in chronic hepatitis C (CHC) patients, which may lead to early termination of treatment. This study aims to investigate the incidence, outcome and predictors of the on-treatment ALT elevation during DAA therapy.CHC patients treated with DAA regimen in Chang Gung Memorial Hospital, Linkou branch during March 2015 to March 2019 were recruited. Prospective scheduled ALT assessment at baseline, 2nd, 4th, 8th, and 12th/24th weeks were recorded. Pretherapy

Effect of sofosbuvir plus daclatasvir for treatment of chronic hepatitis C on patients with psoriasis.

AIM: Until recently, clinicians caring for patients with psoriasis who were infected with hepatitis C virus (HCV) were concerned that treating one condition could exacerbate the other. We evaluated the outcome of treatment with direct-acting antiviral agents (DAAs) on patients with psoriasis having chronic hepatitis C (CHC) infection. PATIENTS AND METHODS: This was an observational prospective cross-sectional study. It included CHC-naive patients with plaque psoriasis. All patients received sofosbuvir plus daclatasvir once daily for 12 weeks for treatment of CHC. Psoriasis area severity index

Recurrence rate of hepatocellular carcinoma in patients with treated hepatocellular carcinoma and hepatitis C virus-associated cirrhosis after ombitasvir/paritaprevir/ritonavir+dasabuvir+ribavirin therapy.

INTRODUCTION: Recent studies have suggested a higher recurrence rate of hepatocellular carcinoma (HCC) in patients with a history of HCC and hepatitis C virus (HCV)-associated cirrhosis treated with direct-acting antiviral (DAA) agents. MATERIAL AND METHODS: We conducted a prospective analysis of 24 patients with HCV-associated cirrhosis and treated HCC who received ombitasvir/paritaprevir/ritonavir+dasabuvir+ribavirin for 12 weeks. Prior therapies for HCC included resection (9/24 patients), radiofrequency ablation (RFA) (7/24) and trans-arterial chemoembolization (TACE) (8/24). All patients
