Antibody repertoire associated with clinically diverse presentations of pediatric SARS-CoV-2 infection.

Pediatric SARS-CoV-2 infection results in clinical presentations ranging from asymptomatic/mild infection to severe pulmonary COVID-19, to Multisystem Inflammatory Syndrome in Children (MIS-C), characterized by hyperinflammation and multi-organ involvement. While various aspects of antibody responses to pediatric SARS-CoV-2 infection manifestations have been reported, parallel studies of antibody responses to viral and self-antigens are understudied. We tested whether clinical presentations of increasing severity corresponded to different antiviral antibody and autoantibody signatures.

Comparative Effectiveness and Durability of Biologics Through 24 Months for Patients with Moderate-to-Severe Psoriasis: Results from the International, Observational Psoriasis Study of Health Outcomes (PSoHO).

Introduction: The Psoriasis Study of Health Outcomes (PSoHO) is an international, prospective, non-interventional study investigating the comparative effectiveness and durability of biologic treatments for patients with moderate-to-severe psoriasis (PsO) over 36 months. Patients were grouped into cohorts based on biologic class: anti-interleukin (IL)-17A/receptor A (anti-IL-17A), anti-IL-12/23, anti-IL-23 and anti-tumor necrosis factor (TNF)-α for the purpose of comparison. Additionally, the durability and effectiveness of individual biologic treatments were compared to ixekizumab (IXE).

The hf-PGA is a valid and reliable measure of hand/foot psoriasis severity in adults: results from a phase 2b clinical trial.

The objective was to investigate the reliability, validity, and meaningful change scores for the Physician's Global Assessment of Hands and/or Feet (hf-PGA), a measure of clinician-reported psoriasis severity on the hands/feet. Baseline, Week 8, and Week 16 data were analyzed from adult patients with moderate to severe plaque psoriasis ( = 99) in a Phase 2b multicenter, randomized, placebo-controlled, dose-ranging study (NCT05223868). The hf-PGA had high test-retest reliability between Weeks 8 and 16 in a clinically stable subgroup ( = 0.

Dupilumab versus Lebrikizumab Demonstrates Greater Likelihood of Achieving and Maintaining Improvements in Efficacy Outcomes Using a Placebo-Adjusted Indirect Treatment Comparison.

Introduction: Dupilumab and lebrikizumab have demonstrated efficacy in atopic dermatitis (AD) clinical trials; however, no direct comparisons exist.

Methods: Efficacy outcome achievement (dupilumab and lebrikizumab with topical corticosteroids [TCS]) at 16 weeks and efficacy outcomes maintenance (dupilumab and lebrikizumab monotherapy without TCS) at 52 weeks were assessed using a placebo-adjusted Bucher indirect treatment comparison (ITC). Week 16 data were sourced from LIBERTY AD CHRONOS (dupilumab, n = 106; placebo, n = 315) and ADhere (lebrikizumab, n = 145; placebo, n = 66) trials.

Antibody-Fab and -Fc features promote Mycobacterium tuberculosis restriction.

Mycobacterium tuberculosis, the causative agent of tuberculosis (TB), a leading cause of death by an infectious disease globally, has no efficacious vaccine. Antibodies are implicated in M. tuberculosis control, but the mechanisms of action remain poorly understood.
