Background And Purpose

We investigated the contribution of several cytokines in the pathogenesis of first-onset neuromyelitis optica spectrum disorder (NMOSD) and determined the differences between aquaporin 4 immunoglobulin G (AQP4-IgG)-positive and AQP4-IgG-negative subtypes.

Method

We enrolled 18 NMOSD (10 AQP4-IgG-positive and 8 AQP4-IgGnegative) and 8 multiple sclerosis (MS) patients, whose serum and cerebrospinal fluid (CSF) samples were collected during the acute phase of the first onset before immunotherapy. Fifteen patients with other noninflammatory neurological diseases (OND) were also included. The serum and CSF levels of interleukin (IL)-6, IL-10, IL-17, IL-21, IL-23, transforming growth factor (TGF)-β1 and the CSF levels of 3 biomarkers of axonal loss and astrocytic damage were measured using the human cytokine multiplex assay or ELISA

Conclusion

IL-6 plays a role in the pathogenetic process of NMOSD, especially in the AQP4-IgG-positive subtype. Distinct pathogenesis exists between AQP4-IgG-positive and AQP4-IgG-negative NMOSD in the initial phase of the disease.

Main results

Serum levels of IL-10 and TGF-β1 and CSF levels of IL-6, IL-10, and TGF-β1 were significantly increased in first onset NMOSD compared to in OND patients. In a subgroup analysis, the CSF levels of IL-6, neurofilament light protein (NFL), S100B, and glial fibrillary acidic protein (GFAP) were significantly more elevated in the AQP4-IgG-positive patients than in the AQP4-IgG-negative NMOSD patients. Correlations were found between the CSF cytokines and tissue damage biomarkers and the clinical findings in NMOSD patients. Notably, the CSF IL-6 level had the strongest correlation with the tissue damage biomarkers and it also correlated with CSF white blood cell (WBC) count.
