Serum Albumin and Inflammation–Nutrition Burden in Adult Hospitalized Atopic Dermatitis: A Case–Control Study with Complementary Genetic Evidence

Background

Atopic dermatitis (AD) is a chronic inflammatory skin disease that may involve systemic inflammation and metabolic disturbance. Serum albumin (Alb) is a routinely available negative acute-phase protein, but its association with hospitalized AD and sphingomyelin-related metabolic signals remains unclear.
