Objective: To investigate the factors related to the prognosis of neuromyelitis optica spectrum disorder (NMOSD) in cerebrospinal fluid and peripheral blood examination. Methods: In this study, we collected 111 patients who were admitted to the First Affiliated Hospital of Zhengzhou University between January 2016 and January 2018 and diagnosed with NMOSD. The patients were divided into the relapse group (n=48) and remission group (n=67). Before treatment, all the patients underwent a routine cerebrospinal fluid (CSF) and peripheral blood test on the second morning of admission. The association between laboratory data and disease prognosis was evaluated. Results: The immunoglobulin G (IgG) level in the serum showed a strong correlation with the relapse of patients, especially in the aquaporin-4-Antibody (AQP4-Ab) positive group (p<0.01). A high level of serum IgG concentration was associated with the relapse of NMOSD, especially in the anti-AQP4 positive group. The area under the receiver operating characteristic (ROC) curve of serum IgG level was 0.888 (p0.001, 95%CI: 0.808-0.968). The ratio of neutrophils to lymphocytes (NLR) was associated with the disability degree of NMOSD patients in 3 years. The NLR value was a linear correlation with final Expanded Disability Status Scale (EDSS) scores. Patients with a high level of NLR value presented an increased degree of disability in the following three years (R2=0.053, p=0.015). Conclusion: The serum IgG level and NLR of first-attack patients were correlated with the prognosis of NMOSD.

Local synthesis of antibodies and presence of oligoclonal bands in the cerebrospinal fluid (CSF) are hallmarks of multiple sclerosis (MS). We investigated the frequency of antibodies against mycobacterial and relevant human epitopes in the CSF of patients with MS or neuromyelitis optica spectrum disorder (NMOSD) and whether these antibodies differed from those present in the serum. Matched serum and CSF samples from 46 patients with MS, 42 patients with NMOSD, and 29 age-matched and sex-matched control subjects were screened retrospectively for the presence of antibodies against Mycobacterium avium subsp. paratuberculosis (MAP) pentapeptide (MAP_5p), MAP_2694295–303, and myelin basic protein (MBP)85–98 peptides by using indirect ELISA. Serum levels of anti-MAP_5p and anti-MAP_2694295–303 antibodies were highly prevalent in patients with MS when compared to patients with NMOSD and controls. Several patients with MS had detectable anti-MAP_5p and anti-MAP_2694295–303 antibodies in the CSF. Furthermore, a group of patients with MS showed intrathecally restricted production of antibodies against these peptides. Women appeared to mount a stronger humoral response to mycobacterial peptides than men. No significant difference in the frequency of anti-MBP85–98 antibodies was found between patients with MS and those with NMOSD. These data highlight the zoonotic potential of MAP, which suggests its involvement in MS etiopathogenesis.

Neuromyelitis optica spectrum disorder (NMOSD) is a rare inflammatory demyelinating disease. Anti-aquaporin-4 antibodies serve as a specific biomarker, while other factors including antecedent infection may also play a role in the development of NMOSD. Abnormal cerebrospinal fluid (CSF) findings such as leukocytosis with concentration >50/mm<sup>3</sup> are one of the characteristics of NMOSD, but these were not specific for identifying other infective neurological diseases. Here we describe a rare case of NMOSD with CSF findings suggestive of bacterial meningomyelitis.
