Evaluation of Intestinal Permeability Using Serum Biomarkers in Learning Early About Peanut Allergy Trial.

Background: Intestinal barrier dysfunction may lead to a break in tolerance and development of food allergy (FA). There is contradictory evidence on whether intestinal permeability (IP) is altered in IgE-mediated FA. Thus, we sought to determine whether IP differed between children with eczema who did (FA group) or did not (atopic controls, ACs) develop FA and whether peanut sensitization, allergy, and early introduction impacted IP using serum biomarkers zonulin, soluble CD14, and Intestinal Fatty Acid Binding Protein among randomly selected participants enrolled in the Learning Early About Peanut allergy trial.

Real-world multicentre cohort study on choices and effectiveness of immunotherapies in NMOSD and MOGAD.

Background: Recurrent attacks in neuromyelitis optica spectrum disorders (NMOSDs) or myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) can lead to severe disability. We aimed to analyse the real-world use of immunotherapies in patients with NMOSD and MOGAD, focusing on changes in treatment strategies, effects on attack rates (ARR) and risk factors for attacks.

Methods: This longitudinal registry-based cohort study included 493 patients (320 with aquaporin-4 immunoglobulin G (AQP4-IgG) seropositive NMOSD (65%), 44 with AQP4-IgG seronegative NMOSD (9%) and 129 MOGAD (26%)) with 1247 treatments from 19 German and one Austrian centre from the registry of the neuromyelitis optica study group (NEMOS).

Visual quality of life in NMOSD and MOGAD: profiles, dynamics and associations with ageing and vision.

Objective: In this multicentric study, we were interested in the vision-related quality of life and its association with visual impairment in neuromyelitis optica spectrum disorders (NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) in comparison to multiple sclerosis (MS) and healthy controls.

Methods: We analysed extracted data from the German NEMOS registry including National Eye Institute Visual Function Questionnaire (NEI-VFQ) scores, high and low contrast visual acuity (HCVA, LCVA), visually evoked potentials (VEP) and the scores for the expanded disability status scale (EDSS) and other neurological tests which assessed their disease-related impairment. The mean follow-up time of our patients was 1.

RENEWED: A follow-up study of the opicinumab phase 2 RENEW study in participants with acute optic neuritis.

Background: The randomized, phase 2 RENEW trial (NCT01721161) evaluated efficacy/safety of opicinumab (anti-LINGO-1) versus placebo in patients with first-episode unilateral acute optic neuritis (AON). Although no significant differences in the latency recovery of visual evoked potential (VEP) were observed between opicinumab and placebo groups in the intention to treat (ITT) population, the prespecified per-protocol (PP) population showed better recovery with opicinumab than with placebo. RENEWED (NCT02657915) was a one-visit, follow-up study 2 years after the last RENEW study visit (Week 32) designed to assess the long-term electrophysiological and clinical outcomes for participants previously enrolled and having received study treatment in RENEW.
