RESUMO

To evaluate the safety and tolerability of the fixed-dose, single-tablet regimen sofosbuvir/velpatasvir (SOF/VEL) for the treatment of hepatitis C virus (HCV) infection in three Phase 3 studies in patients with and without compensated cirrhosis. Data from three registrational trials (ASTRAL-1, NCT02201940; ASTRAL-2, NCT02220998; ASTRAL-3, NCT02201953) were pooled by treatment regimen. Researchers assessed treatment-emergent adverse events (TEAEs) and laboratory abnormalities in patients randomized to SOF/VEL or placebo for 12 weeks in ASTRAL-1 and SOF/VEL for 12 weeks in ASTRAL-2 and ASTRAL-3. Overall, 1035 patients were treated with SOF/VEL, and 116 patients received placebo. Rates of any TEAE were generally similar between patients receiving SOF/VEL (79.4%) and those receiving placebo (76.7%). The majority of TEAEs were mild to moderate, with 23 (2.2%) treatment-emergent serious AEs in patients treated with SOF/VEL. Of these treatment-emergent serious AEs, none led to premature study discontinuation, nor were they considered related to treatment. Presence of compensated cirrhosis, greater age and mild renal impairment did not impact incidence or severity of TEAEs with SOF/VEL treatment. The most common TEAEs (incidence ≥10%) were headache, fatigue, nausea and nasopharyngitis in patients receiving SOF/VEL; similar rates were observed in placebo-treated patients. Three deaths (<1%) were reported in patients treated with SOF/VEL, all posttreatment and none assessed as related to study treatment. Similar to that of placebo, SOF/VEL treatment of HCV infection had a safety/tolerability profile that was not affected by baseline factors, such as the presence of compensated cirrhosis, mild renal impairment or advanced age.

RESUMO

BACKGROUND AND AIMS: Alcoholic hepatitis (AH) is a severe condition with poor short-term prognosis. Specific treatment with corticosteroids slightly improves short-term survival but is associated with infection and is not used in many centers. A reliable method to identify patients who will recover spontaneously will minimise the numbers of patients who experience side effects of available treatments. METHODS: We analysed the trajectory of serum bilirubin concentration over the course of hospital admissions in patients with AH to predict spontaneous survival and the need for treatment. RESULTS: data from 426 patients were analysed. Based on bilirubin trajectory, patients were categorized into three groups: 'fast fallers' (bilirubin <0.8 x admission value at day 7), 'static' (bilirubin of >0.9 - <1.2 x admission value) and 'rapid risers' (bilirubin of ≥1.2 x admission bilirubin). Fast fallers had significantly better 90-day survival compared to other groups (log rank p < .001), and showed no benefit of corticosteroid therapy (OR for survival at 28 days of treatment, 0.94, 95% CI 0.06 - 8.41). These findings remained even amongst patients with severe disease based on initial DF, GAHS or MELD scores. CONCLUSIONS: We present an intuitive method of classifying patients with AH based on the trajectory of bilirubin over the first week of admission. It is complimentary to existing scores that identify candidates for corticosteroid treatment or assess response to treatment. This method identifies a group of patients with AH who recover spontaneously and can avoid corticosteroid therapy.

RESUMO

BACKGROUND & AIMS: We recently showed that alcoholic hepatitis (AH) is characterized by dedifferentiation of hepatocytes and loss of mature functions. Glucose metabolism is tightly regulated in healthy hepatocytes. We hypothesize that AH may lead to metabolic reprogramming of the liver, including dysregulation of glucose metabolism. METHODS: We performed integrated metabolomic and transcriptomic analyses of liver tissue from patients with AH or alcoholic cirrhosis or normal liver tissue from hepatic resection. Focused analyses of chromatin immunoprecipitation coupled to DNA sequencing was performed. Functional in vitro studies were performed in primary rat and human hepatocytes and HepG2 cells. RESULTS: Patients with AH exhibited specific changes in the levels of intermediates of glycolysis/gluconeogenesis, the tricarboxylic acid cycle, and monosaccharide and disaccharide metabolism. Integrated analysis of the transcriptome and metabolome showed the used of alternate energetic pathways, metabolite sinks and bottlenecks, and dysregulated glucose storage in patients with AH. Among genes involved in glucose metabolism, hexokinase domain containing 1 (HKDC1) was identified as the most up-regulated kinase in patients with AH. Histone active promoter and enhancer markers were increased in the HKDC1 genomic region. High HKDC1 levels were associated with the development of acute kidney injury and decreased survival. Increased HKDC1 activity contributed to the accumulation of glucose-6-P and glycogen in primary rat hepatocytes. CONCLUSIONS: Altered metabolite levels and messenger RNA expression of metabolic enzymes suggest the existence of extensive reprogramming of glucose metabolism in AH. Increased HKDC1 expression may contribute to dysregulated glucose metabolism and represents a novel biomarker and therapeutic target for AH.
