Chronic HBV hepatitis patients responding to interferon treatment had a faster, more complete, and sustained clearance of viral markers than controls; HCV coinfection does not seem to negatively affect the clearance of HBV replicative markers. However when coinfection occurs, hepatic disease persists despite HBV marker clearance.

BackgroundGastric electric stimulation (GES) is a treatment approach to refractory gastroparesis, possibly acting centrally via afferent vagus nerve stimulation (VNS). Non-invasive VNS (nVNS) is a potential alternative to GES that could eliminate the safety risks of or identify likely responders to implantable neurostimulators.ObjectiveThis open-label proof-of-concept study assessed the effects of nVNS in patients with severe drug-refractory gastroparesis.MethodsPatients used the Gastroparesis Cardinal Symptom Index (GCSI) to grade symptoms in diaries daily for 2 weeks before treatment (baseline) and during ≥3 weeks of nVNS therapy. Adverse events (AEs) were also diarised. Treatment was self-administered using an nVNS device (gammaCore, electroCore) and consisted of 120 s stimulations to the vagus nerve in the neck (two stimulations to each side three times daily during weeks 1 and 2; three stimulations to each side three times daily during week 3 and beyond). Response was defined as a ≥1 point decrease from baseline in GCSI score.ResultsThirty-five patients enrolled; 23 were compliant with study procedures and were included in the analysis; 7 continued treatment beyond 3 weeks. Response rates were 35% (8/23) at 3 weeks and 43% (10/23) for the duration of therapy (3–6 weeks). For the entire cohort and the 10 responders, improvements from baseline were noted for mean total GCSI and GCSI subscale scores (nausea/vomiting, postprandial fullness/early satiety, bloating). No serious AEs were reported.ConclusionsThese preliminary results provide a signal that nVNS may be useful for treating refractory gastroparesis. Larger controlled studies are warranted.

When compared side-by-side, all the major findings on OGD are seen on Cap-OGD while there is under-reporting of minor findings. Previous experience of ESO-2 capsule reporting improves reading accuracy and indicates the need for training. This pilot study provides a backdrop to explore the possible role of Cap-OGD, especially where patients are reluctant to undergo conventional OGD or where there is risk of prion contamination of the endoscope.
