Abstract

We performed a cross-sectional study using validated survey instruments, finding severe pruritus, reduced quality of life (QoL) and a significant mental health burden in a diverse cohort of patients with prurigo nodularis (PN) from the USA. Itch severity and QoL scores were comparable to those found in European populations, aside from ItchyQoL scores (higher scores in this US cohort). Black patients reported higher itch intensity scores than White patients. More than 37% of patients met the cutoff for severe depression, but only 26% had a clinical diagnosis of depression. Dermatologists should be aware that PN extends beyond severe pruritus, consider screening for psychiatric comorbidities and address other concerns that affect QoL as needed.
