TLDR Higher IL-17A levels indicate more severe alopecia areata.
In a study involving 36 patients with alopecia areata (AA) and 20 healthy controls, researchers found that serum interleukin-17A (IL-17A) levels were significantly higher in AA patients (P=0.004). Higher IL-17A levels correlated with more severe disease, personal atopy, nail abnormalities, and active disease phases. These results suggest that IL-17A is crucial in AA pathogenesis and could serve as a valuable clinical biomarker for disease severity and activity.
