Abstract
Importance: Alopecia areata (AA) has been associated with multiple comorbidities, yet information regarding the timing of comorbidity development after AA diagnosis is limited.
Objective: To evaluate the prevalence and new-onset incidence of psychiatric and autoimmune comorbidities in patients with AA in the US.
Design, setting, and participants: This retrospective cohort analysis used data collected from January 1, 2007, to April 30, 2023, from the Merative MarketScan Research Databases, which contains medical and drug claims data from more than 46 million patients in the US. Data from adolescent and adult patients (aged 12-64 years) diagnosed with AA and patients without AA (ie, controls) were evaluated. For some analyses, patients with AA were matched (1:4) to controls based on sex, age, and geographic region.
Main outcomes and measures: Prevalence (at the time of AA diagnosis) and incidence (new onset after AA diagnosis) of psychiatric and autoimmune diseases were reported as percentage of patients. Risk of developing a new-onset psychiatric or autoimmune disease after AA diagnosis was calculated as adjusted hazard ratios (AHRs) with 95% CIs.
Results: At baseline, 63 384 patients with AA and 3 309 107 without AA were identified. After matching, there were 16 512 and 66 048 patients in the AA and control groups, respectively, with a mean (SD) age of 36.9 (13.4) years and 50.6% of whom were female. Compared with the unmatched controls, patients with AA had higher prevalence of psychiatric (30.9% vs 26.8%; P < .001) and autoimmune (16.1% vs 8.9%; P < .0001) comorbidities at AA diagnosis; incidence was also higher in patients with AA (without history of these comorbidities) vs the matched control group. Patients with AA vs controls had a significantly higher risk of developing a psychiatric (AHR, 1.3; 95% CI, 1.3-1.4) or autoimmune (AHR, 2.7; 95% CI, 2.5-2.8) comorbidity.
Conclusions and relevance: In this cohort study, patients with AA had a higher prevalence of autoimmune and psychiatric comorbidities at AA diagnosis and demonstrated an elevated risk of new-onset autoimmune and psychiatric comorbidities after their diagnosis. These data highlight the most common comorbidities among patients with AA and may help physicians counsel and monitor patients newly diagnosed with AA.
期刊介绍:
JAMA Dermatology is an international peer-reviewed journal that has been in continuous publication since 1882. It began publication by the American Medical Association in 1920 as Archives of Dermatology and Syphilology. The journal publishes material that helps in the development and testing of the effectiveness of diagnosis and treatment in medical and surgical dermatology, pediatric and geriatric dermatology, and oncologic and aesthetic dermatologic surgery.
JAMA Dermatology is a member of the JAMA Network, a consortium of peer-reviewed, general medical and specialty publications. It is published online weekly, every Wednesday, and in 12 print/online issues a year. The mission of the journal is to elevate the art and science of health and diseases of skin, hair, nails, and mucous membranes, and their treatment, with the aim of enabling dermatologists to deliver evidence-based, high-value medical and surgical dermatologic care.
The journal publishes a broad range of innovative studies and trials that shift research and clinical practice paradigms, expand the understanding of the burden of dermatologic diseases and key outcomes, improve the practice of dermatology, and ensure equitable care to all patients. It also features research and opinion examining ethical, moral, socioeconomic, educational, and political issues relevant to dermatologists, aiming to enable ongoing improvement to the workforce, scope of practice, and the training of future dermatologists.
JAMA Dermatology aims to be a leader in developing initiatives to improve diversity, equity, and inclusion within the specialty and within dermatology medical publishing.
