Metabolic syndrome in patients with Alopecia Areata: A case-control study.

Abstract

The aim of this study was to evaluate metabolic syndrome prevalence in patients with Alopecia Areata compared to controls. Sixty eligible patients with Alopecia Areata and 60 healthy subjects frequency matched for age and sex attending to our referral dermatology clinics from 2015 to 2017 were enrolled. Prevalence of metabolic syndrome and its components were compared between the two groups. Metabolic syndrome was only seen in seven patients (11.67%) and four controls (6.67%) without a significant difference (P= .34). The clinical presentations of AA included patch type (38.33%), ophiasis (6.67%), alopecia totalis (16.67%), and alopecia universalis (38.33%). Presence of metabolic syndrome was significantly associated with abdominal circumference (OR: 1.10, 95% CI for OR: 1.02to 1.19). Although there was no significant association between Alopecia Areata and metabolic syndrome, some components of metabolic syndrome were more prevalent in these patients. It may be concluded Alopecia Areata patients are at a higher risk of developing metabolic syndrome in the future. Further studies with larger sample sizes are needed.
