Increased serum IL-36β and IL-36γ levels in patients with neuromyelitis optica spectrum disorders: association with disease activity
Abstract
Abstract Background Interleukin 36 (IL-36) cytokines belong to the IL-1 family and play an important role in some autoimmune diseases. However, the relationship between IL-36 and neuromyelitis optica spectrum disorders (NMOSD) remains unclear. Methods We determined serum IL-36α, IL-36β and IL-36γ levels and assessed correlations with clinical characteristics in 50 NMOSD patients and 30 healthy controls (HC). Results The concentrations of serum IL-36β and IL-36γ were significantly higher in patients with NMOSD than in HCs and decreased during remission. Serum IL-36β levels were positively correlated with the annual relapse rate (ARR), spinal cord lesion length and Expanded Disability Status Scale (EDSS) scores. Conclusions Serum IL-36β and IL-36γ levels were related to disease activity in NMOSD patients and may be important biomarkers of NMOSD.
