TOPLINE:
Patients with alopecia areata (AA) had a higher prevalence of several psychiatric and autoimmune comorbidities at baseline and were at greater risk of developing those comorbidities after diagnosis.
METHODOLOGY:
Researchers evaluated 63,384 patients with AA and 3,309,107 individuals without AA (aged 12-64 years) from the Merative MarketScan Research Databases.
The matched cohorts included 16,512 patients with AA and 66,048 control individuals.
Outcomes were the prevalence of psychiatric and autoimmune diseases at baseline and the incidence of new-onset psychiatric and autoimmune diseases during the year after diagnosis.
TAKEAWAY:
Overall, patients with AA showed a greater prevalence of any psychiatric disease (30.9% vs 26.8%; P < .001) and any immune-mediated or autoimmune disease (16.1% vs 8.9%; P < .0001) than those with controls.
In matched cohorts, patients with AA also showed a higher incidence of any new-onset psychiatric diseases (10.2% vs 6.8%; P < .001) or immune-mediated or autoimmune disease (6.2% vs 1.5%; P <.001) within the first 12 months of AA diagnosis than those with controls.
Among patients with AA, the risk of developing a psychiatric comorbidity was higher (adjusted hazard ratio [aHR], 1.3; 95% CI, 1.3-1.4). The highest risks were seen for adjustment disorder (aHR, 1.5), panic disorder (aHR, 1.4), and sexual dysfunction (aHR, 1.4).
Compared with controls, patients with AA were also at an increased risk of developing immune-mediated or autoimmune comorbidities (aHR, 2.7; 95% CI, 2.5-2.8), with the highest for systemic lupus (aHR, 5.7), atopic dermatitis (aHR, 4.3), and vitiligo (aHR, 3.8).
IN PRACTICE:
“Routine monitoring of patients with AA, especially those at risk of developing comorbidities, may permit earlier and more effective intervention,” the authors wrote.
SOURCE:
The study was led by Arash Mostaghimi, MD, MPA, MPH, Brigham and Women’s Hospital and Harvard University, Boston. It was published online on July 31, 2024, in JAMA Dermatology.
LIMITATIONS:
Causality could not be inferred because of the retrospective nature of the study. Comorbidities were solely diagnosed on the basis of diagnostic codes, and researchers did not have access to characteristics such as lab values that could have indicated any underlying comorbidity before the AA diagnosis. This study also did not account for the varying levels of severity of the disease, which may have led to an underestimation of disease burden and the risk for comorbidities.
DISCLOSURES:
AbbVie provided funding for this study. Mostaghimi disclosed receiving personal fees from Abbvie and several other companies outside of this work. The other four authors were current or former employees of Abbvie and have or may have stock and/or stock options in AbbVie.
