Live Attenuated Vaccine Administration in Children Treated With Methotrexate or Dupilumab.

Background And Objectives: A wholesale recommendation against use of live virus vaccines in patients treated with any medication classified as an immunosuppressant has been based on global theoretical concerns rather than clinical outcomes for specific drugs.

Methods: A retrospective search of electronic medical records identified patients seen by the Allergy and/or Dermatology services between 2017 and 2023 at a pediatric tertiary center who received a live attenuated vaccine during the 6 week interval prior to the first prescription for methotrexate or dupilumab until 6 weeks after the last prescription for either medication. Individual charts of identified patients were manually reviewed for evidence of adverse events.

Analysis of publicly available adverse events reported for pediatric patients treated with Janus kinase inhibitors.

Janus kinase inhibitors (JAKi) are drugs that block tyrosine kinases responsible for transducing cytokine signals. The first JAKi was approved by the US Food and Drug Administration (FDA) in 2011 to treat rheumatoid arthritis in adults. A pediatric indication was not approved until 8 years later, for acute graft-versus-host disease.

Dupilumab Safety and Efficacy up to 1 Year in Children Aged 6 Months to 5 Years with Atopic Dermatitis: Results from a Phase 3 Open-Label Extension Study.

Background: Pediatric patients with moderate-to-severe atopic dermatitis (AD) often experience a high disease burden and have a high risk of persistent disease. Standard-of-care immunosuppressive systemic treatments have been used off-label for AD in pediatric patients despite concerns for suboptimal safety with continuous use and risk of relapse upon discontinuation. The biologic agent dupilumab is the first systemic treatment approved for moderate-to-severe AD in children as young as 6 months.

Indirect costs of reproduction and the tradeoff between offspring size and number: a framework illustrated by fitness costs and benefits of ovarian fluid.

The theory describing the evolution of offspring size often assumes that the production cost per unit volume is the same for small and large offspring. However, this may not be true if indirect costs of reproduction (e.g.

A case series of live attenuated vaccine administration in dupilumab-treated children with atopic dermatitis.

Background And Objective: Current regulatory labeling recommends avoiding live vaccine use in dupilumab-treated patients. Clinical data are not available to support more specific guidance for live or live attenuated vaccines administration in dupilumab-treated patients.

Methods: Children (6 months-5 years old) with moderate-to-severe atopic dermatitis (AD) enrolled in a phase 2/3 clinical trial of dupilumab (LIBERTY AD PRESCHOOL Part A/B; NCT03346434) and subsequently participated in the LIBERTY AD PED-OLE (NCT02612454).

Diagnosis and Management of Pediatric Psoriasis: An Overview for Pediatricians.

Pediatric psoriasis (PsO) and its associated comorbidities carry physical and psychosocial burdens in children and adolescents, which can negatively impact quality of life. However, features distinguishing pediatric PsO from eczema and other common inflammatory skin diseases may not be obvious to primary care providers, which may contribute to underrecognition and misdiagnosis. Accurate diagnosis of pediatric PsO is critical for managing the physical and psychological burdens associated with this disease.

Dupilumab Treatment Leads to Rapid and Consistent Improvement of Atopic Dermatitis in All Anatomical Regions in Patients Aged 6 Months to 5 Years.

Introduction: Atopic dermatitis (AD) is heterogeneous in distribution pattern and clinical features. This analysis assessed the effect of dupilumab on the extent and severity of AD across various signs (erythema, edema/papulation, excoriation, lichenification) in different anatomical regions (head and neck, trunk, upper extremities, lower extremities) in patients aged 6 months to 5 years.

Methods: In LIBERTY AD PRESCHOOL, a double-blind, placebo-controlled, phase III clinical trial, children aged 6 months to 5 years with moderate-to-severe AD were randomized 1:1 to subcutaneous dupilumab or placebo with concomitant low-potency topical corticosteroids (TCS) every 4 weeks for 16 weeks.

Methotrexate for inflammatory skin disease in pediatric patients: Consensus treatment guidelines.

Methotrexate (MTX) is a readily accessible drug, first used in 1948 and employed for a wide variety of indications since then. However, despite widespread off-label use, FDA labeling does not include approved indications for the use of MTX for many inflammatory skin diseases in pediatric patients, including morphea, psoriasis, atopic dermatitis, and alopecia areata, among others. Without published treatment guidelines, some clinicians may be hesitant to use MTX off-label, or uncomfortable prescribing MTX in this population.

Dupilumab Provides Clinically Meaningful Responses in Children Aged 6-11 Years with Severe Atopic Dermatitis: Post Hoc Analysis Results from a Phase III Trial.

Background: Children with severe atopic dermatitis (AD) have a multidimensional disease burden.

Objective: Here we assess the clinically meaningful improvements in AD signs, symptoms, and quality of life (QoL) in children aged 6-11 years with severe AD treated with dupilumab compared with placebo.

Methods: R668-AD-1652 LIBERTY AD PEDS was a randomized, double-blinded, placebo-controlled, parallel-group, phase III clinical trial of dupilumab with concomitant topical corticosteroids (TCS) in children aged 6-11 years with severe AD.

The Sonogashira Coupling on Palladium Milling Balls-A new Reaction Pathway in Mechanochemistry.

Utilizing direct mechanocatalytical conditions, the Sonogashira coupling was successfully performed on the surface of milling tools by using pure Pd and Pd coated steel balls. The optimization of co-catalyst forming additives led to a protocol, which generates quantitative yields under aerobic conditions for various substrates within as little as 90 minutes. Using state-of-the-art spectroscopic, diffractive, as well as in situ methods lead to the identification of a previously unknown and highly reactive complex of the co-catalyst copper.

Practical management of ocular surface disease in patients with atopic dermatitis, with a focus on conjunctivitis: A review.

Atopic dermatitis (AD) is a chronic inflammatory skin disease that can significantly decrease quality of life. AD is commonly associated with comorbidities including ocular surface disease (OSD). Conjunctivitis is the most common OSD associated with AD and can increase in incidence with use of monoclonal antibody biologics that target the type 2 inflammatory pathway.
