TL;DR
Lower serum 25(OH)D levels were significantly associated with increased disease severity in pediatric AD, and seasonal variability in vitamin D levels was examined.
Background: This study was conducted to investigate the correlations and independent associations between serum 25-hydroxyvitamin D (25[OH]D) levels and total immunoglobulin E (IgE) values as well as peripheral blood eosinophil (EOS) counts in adults with atopic dermatitis (AD). Methods: This single-center cross-sectio...
Vitamin D has been implicated in epidermal barrier function and immune regulation, but its clinical relevance in pediatric atopic dermatitis (AD) remains uncertain. This retrospective cross-sectional study aimed to determine the prevalence of vitamin D insufficiency and deficiency in Mexican children with AD and to exp...
Background Vitamin D exerts pleiotropic immunomodulatory effects and has been implicated in autoimmune skin disorders, yet its relationship with vitiligo severity and chronicity remains controversial. Objective To investigate the associations between serum 25-hydroxyvitamin D [25(OH)D] levels and key demographic and cl...
Objective: This study aimed to evaluate serum 25-hydroxyvitamin D [25(OH)D] levels in children aged 0–5 years presenting with lower respiratory tract infection (LRTI) and to investigate the association between vitamin D deficiency and infection severity. Methods: In this prospective controlled study, a total of 100 chi...
Lower serum 25(OH)D was independently associated with greater CSU disease activity in this South Indian cohort, supporting assessment of vitamin D status in CSU and motivating interventional trials of supplementation.
Serum 25(OH)D levels in IBD patients may serve as an additional, useful, and non-invasive marker of disease activity, and a relationship between serum 25(OH)D concentrations in patients with IBD and total dietary vitamin D intake is revealed.
