The TREATgermany disease registry studied 1,134 patients with moderate-to-severe atopic dermatitis (AD) with Scoring Atopic Dermatitis (SCORAD) >20 from German clinics and practices. The findings revealed that 97.2% of patients experienced itch, and its severity was moderately correlated with AD severity scores. Notably, itch had a stronger connection with patient-reported outcomes, like self-reported disease severity and quality of life, compared to physician-assessed objective measures.
