Incidence of fibrosing colonopathy with pancreatic enzyme replacement therapy in patients with cystic fibrosis.

Background: High daily doses of pancreatic enzyme replacement therapy (PERT) were historically associated with risk of fibrosing colonopathy (FC) in people with cystic fibrosis (pwCF), leading to development of PERT dosing guidelines and reformulated products. This study quantified incidence of FC in pwCF treated with PERT following those measures.

Methods: This large prospective cohort study included eligible pwCF enrolled in the Cystic Fibrosis Foundation Patient Registry with ≥1 clinic visit in 2012-2014 and follow-up through 2020.

Infliximab efficacy in rheumatoid arthritis after an inadequate response to etanercept or adalimumab: results of a target-driven active switch study.

Objective: Evaluate efficacy of infliximab with response-driven dosing in patients with active RA.

Research Design And Methods: Patients (n = 203) with active RA despite methotrexate + etanercept/adalimumab, participated in this active-infliximab-switch study. Infliximab 3 mg/kg was infused at Weeks 0, 2, 6, 14, and 22 with escalation to 5 or 7 mg/kg depending on EULAR response at Weeks 14 and 22.

A comparative effectiveness study of adalimumab, etanercept and infliximab in biologically naive and switched rheumatoid arthritis patients: results from the US CORRONA registry.

Purpose: To compare the effectiveness of anti-tumour necrosis factor (TNF) agents in biologically naive and 'switched' rheumatoid arthritis (RA) patients.

Methods: RA patients enrolled in the CORRONA registry newly prescribed adalimumab (n=874), etanercept (n=640), or infliximab (n=728) were stratified based on previous anti-TNF use. Clinical effectiveness at 6, 12 and 24 months was examined using the modified American College of Rheumatology response criteria (mACR20/50/70) and achievement of remission (28-joint disease activity score (DAS28) and clinical disease activity index (CDAI)) in unadjusted and adjusted analyses.

The action of 10 mg famotidine versus 200 mg cimetidine: onset and magnitude of antisecretory action within the first 2 hours after administration.

The introduction of over-the-counter histamine2 -receptor antagonists (H2 -RAs) makes it important to characterize these agents in terms of their different times to onset of action and magnitude of effect. The time to onset of action and the degree of gastric acid inhibition of the H2 -RAs famotidine and cimetidine at dosage levels approved for over-the-counter use (10 mg famotidine and 200 mg cimetidine) were compared. Twenty-four subjects with a history of heartburn of at least 2 months duration received 10 mg famotidine, 200 mg cimetidine, or placebo in a randomly assigned sequence of three treatment periods.
