TLDR Alopecia areata patients are more likely to develop systemic lupus erythematosus.
This nationwide case-control study investigated the prevalence of systemic lupus erythematosus (SLE) in patients with alopecia areata (AA) using data from 33,401 AA patients and 66,802 matched controls. The study found a significant association between AA and SLE, with an odds ratio of 3.63, indicating that AA patients are more likely to develop SLE compared to controls. This association was consistent across all age groups, with the strongest link observed in children. The study highlights the importance of screening and monitoring AA patients for SLE, as well as considering early targeted treatments like Janus kinase inhibitors, which are being explored for both conditions. Despite its strengths, the study was limited by the lack of data on AA severity and specific SLE subtypes.
