The following article is part of coverage from the American Academy of Dermatology’s Annual Meeting (AAD 2020). Because of concerns regarding the coronavirus disease 2019 (COVID-19) pandemic, all AAD 2020 sessions and presentations were transitioned to a virtual format.

Prurigo nodularis (PN) and lichen simplex chronicus (LSC) are linked to mental health disorders and emergencies requiring hospitalization, according to study results presented at the American Academy of Dermatology’s Virtual Meeting Experience (AAD VMX) 2020, held online from June 12 to 14, 2020.
Psychosocial distress has been associated with both PN and LSC, which can be devastating pruritic diseases; however, not much is known about mental health comorbidities in these diseases. Researchers examined data from the 2002-2012 Nationwide Inpatient Sample and a representative sample of approximately 20% of annual hospitalizations in the United States (n=87,053,155). In the study population, 10,210 patients had an inpatient diagnoses of PN or LSC.
In a multivariable logistic regression, PN and LSC were associated with having 1 or more mental health disorders (adjusted odds ratio [aOR], 2.26; 95% CI, 2.13-2.41). All 15 mental health disorders were linked to PN and LSC, including personality, impulse control, attention-deficit/hyperactivity, developmental, pediatric, psychotic, substance use, mood, anxiety, adjustment, and cognitive disorders. Suicide or intentional self-inflicted injury and a history of mental health disorders or addiction were also significantly correlated with PN and LSC.
Furthermore, PN and LSC were associated with increased primary hospitalization (aOR, 2.16; 95% CI, 1.91-2.45) for 5 of the mental health disorders analyzed, specifically developmental, psychotic, cognitive, and mood disorders, as well as a history of mental health disorders.
The researchers concluded, “Future research is warranted to improve the screening and management of MH disorders in PN/LSC patients.”
