Incidence and prevalence of prurigo nodularis and associated comorbidities in Denmark from 1998 to 2021

The findings indicate a significant association between PN and various comorbidities, emphasizing the need for multidisciplinary care. The increase in prevalence suggests a growing burden of disease. Although the study may underestimate the true prevalence of PN because of reliance on hospital records, it reveals a rising rate prevalence of PN and associated comorbidities in Denmark. The observed high prevalence of mental health problems in individuals with PN should be a focus of concern for the treating physicians.
