Elevated serum levels of interleukin-17A in uveitis patients.

ABSTRACT: T helper 17 cells (Th17) are one of the main pathogenic effectors in autoimmune uveitis, and IL-17A is the signature cytokine of Th17 cells. This study aims to assess serum IL-17A levels in patients with autoimmune uveitis and evaluate associations between IL-17A levels and disease characteristics.Serum IL-17A levels from 87 autoimmune uveitis patients and 60 healthy controls were assessed using an enzyme-linked immunosorbent assay. Among this cohort, 9 patients were followed longitudinally for IL-17A levels during active and inactive stages of their disease.Median serum IL-17A levels were higher among uveitis patients compared to controls (p < 0.0001). Moreover, IL-17A levels were elevated among uveitis patients with active disease compared to those with inactive disease (p = 0.0202). Among the 9 patients followed longitudinally, IL-17A levels were elevated during active disease compared to the inactive stage (p = 0.0078).Serum IL-17A levels are elevated in uveitis patients, particularly in active uveitis.
