Elbasvir/Grazoprevir, an Alternative in Antiviral Hepatitis C Therapy in Patients under Amiodarone Treatment

A sofosbuvir/ledipasvir combination is part of a first-line treatment of hepatitis C. However, in patients concurrently treated with amiodarone, cardiac side effects have been described, resulting in an official warning in 2015 by the American Food and Drug Administration and the European Medicines Agency when combining those substances. This deprived numerous hepatitis C patients with concurrent cardiovascular problems of receiving this highly effective treatment. Here we present a treatment alternative with an elbasvir/grazoprevir regimen, based on our successful treatment of a patient under concurrent amiodarone therapy. Our observations indicate that patients treated with amiodarone can finally benefit from effective antiviral therapy

Short‐term fully closed‐loop insulin delivery using faster insulin aspart compared to standard insulin aspart in type 2 diabetes

We evaluated the efficacy and safety of short‐term fully closed‐loop insulin delivery using faster versus standard insulin aspart in type 2 diabetes. Fifteen adults with insulin‐treated type 2 diabetes underwent 22 hours of closed‐loop insulin delivery with either faster or standard insulin aspart in a double‐blind randomised crossover design. Basal‐bolus regimen was replaced by model predictive control algorithm‐directed insulin delivery based on sensor glucose levels. The primary outcome was time with plasma glucose in target range (5.6‐10.0mmol/l) and did not differ between treatments (mean difference [95%CI] ‐3.3% [8.2;1.7], p=0.17). Mean glucose and glucose variability were comparable, as was time spent below and above target range. Hypoglycaemia (<3.5mmol/l) occurred once with faster insulin aspart and twice with standard insulin aspart. Mean total insulin dose was higher with faster insulin aspart (mean difference [95%CI] 3.7U [0.7;6.8], p=0.021). No episodes of severe hypoglycaemia or other serious adverse events occurred. In conclusion, short‐term fully closed‐loop in type 2 diabetes may require higher dose of faster insulin aspart compared to standard insulin aspart to achieve comparable glucose control.Swiss National Science Foundation (P1BEP3_165297), UDEM Scientific Fund, Cambridge Biomedical Research Centre - NIHR

Arginine vasopressin (AVP) and treatment with arginine vasopressin receptor antagonists (vaptans) in congestive heart failure, liver cirrhosis and syndrome of inappropriate antidiuretic hormone secretion (SIADH)

International audienceArginine vasopressin (AVP) is the major physiological regulator of renal water excretion and blood volume. The AVP pathways of VR-mediated vasoconstriction and VR-induced water retention represent a potentially attractive target of therapy for edematous diseases. Experimental and clinical evidence suggests beneficial effects of AVP receptor antagonists by increasing free water excretion and serum sodium levels. This review provides an update on the therapeutic implication of newly developed AVP receptor antagonists in respective disorders, such as chronic heart failure, liver cirrhosis and syndrome of inappropriate antidiuretic hormone secretion

Elevated levels of endocannabinoids in chronic hepatitis C may modulate cellular immune response and hepatic stellate cell activation.

The endocannabinoid (EC) system is implicated in many chronic liver diseases, including hepatitis C viral (HCV) infection. Cannabis consumption is associated with fibrosis progression in patients with chronic hepatitis C (CHC), however, the role of ECs in the development of CHC has never been explored. To study this question, anandamide (AEA) and 2-arachidonoyl glycerol (2-AG) were quantified in samples of HCV patients and healthy controls by gas and liquid chromatography mass spectrometry. Fatty acid amide hydrolase (FAAH) and monoaclyglycerol lipase (MAGL) activity was assessed by [3H]AEA and [3H]2-AG hydrolysis, respectively. Gene expression and cytokine release were assayed by TaqMan PCR and ELISpot, respectively. AEA and 2-AG levels were increased in plasma of HCV patients, but not in liver tissues. Hepatic FAAH and MAGL activity was not changed. In peripheral blood mononuclear cells (PBMC), ECs inhibited IFN-γ, TNF-α, and IL-2 secretion. Inhibition of IL-2 by endogenous AEA was stronger in PBMC from HCV patients. In hepatocytes, 2-AG induced the expression of IL-6, -17A, -32 and COX-2, and enhanced activation of hepatic stellate cells (HSC) co-cultivated with PBMC from subjects with CHC. In conclusion, ECs are increased in plasma of patients with CHC and might reveal immunosuppressive and profibrogenic effects
