Nailfold Capillaroscopic Findings in Alopecia Areata Patients: Pilot Results

This study investigated microcirculatory changes in 47 patients with alopecia areata compared to 50 controls using nailfold capillaroscopy. Results showed that the patient group had significantly higher capillary density and capillary density scores than the control group, with mean values of 8.27 capillary/mm and 0.89, respectively. Additionally, avascular areas were found in 6% of patients, and neovascularization was detected in 17% of patients, but not in controls. These findings suggest a possible association between alopecia areata and microcirculatory alterations.
