Abstract Background To investigate the relationship between the neutrophil-to-lymphocyte ratio (NLR) and prognosis after the first attack of optic neuromyelitis optica spectrum disorder (NMOSD). Methods In this retrospective study, we included the medical records of 324 patients with first episode NMOSD and collected data on clinical parameters. Follow-up extended disability status scale (EDSS) score and relapse rate were analyzed using logistic regression models to determine the independent effect of NLR on outcomes; receiver operating characteristic (ROC) curves were applied to analyze the predictive value of NLR for the prognosis of NMOSD. Interaction and stratification analyses were used to explore the association between NLR and prognosis of patients with NMOSD, and Kaplan-Meier analysis was used to investigate the relationship between NLR and outcome. The association between NLR level with relapse rate and poor recovery was assessed by a Cox regression analysis. Results Patients in the high-NLR group had significantly higher EDSS scores and relapse rates at follow-up (both, P < 0.001) than did those in the low-NLR group. Univariate analysis showed revealed that NLR was significantly associated with relapse (odds ratio [OR] = 1.28, 95% confidence interval [CI]: 1.16–1.41, P < 0.001) and poor recovery (OR = 1.32, 95% CI: 1.20–1.46, P < 0.001), and these associations remained significant, even after multifactorial analysis (OR = 1.33, 95% CI: 1.11–1.59, P = 0.002; OR = 1.23, 95% CI: 1.06–1.43, P = 0.007, respectively). Stratified analysis showed that sex, platelet-to-lymphocyte ratio (PLR) level, and lymphocyte-to-monocyte technical ratio (LMR) level were strongly associated with relapse owing to elevated NLR; Kaplan-Meier survival curve analysis showed that the median time to relapse was significantly lower in the high-NLR group than in the low-NLR group (P < 0.001). A multivariate analysis showed a significant relationship between NLR level with relapse (HR = 1.07, 95%CI: 1.03–1.10, P = 0.001) and poor recovery (HR = 1.08, 95%CI: 1.04–1.11, P = 0.001). Conclusions NLR may be used as a prognostic indicator for first onset NMOSD, and a high NLR may be significantly associated with high relapse rates and poor recovery.

Understanding the characteristics of neuromyelitis optica spectrum disorder (NMOSD) with recurrent short partial transverse myelitis (SPTM), which is very rare, contributes to the differential diagnosis of multiple sclerosis (MS). We present two Chinese aquaporin-4 immunoglobulin G (AQP4-IgG)-seropositive NMOSD cases who had at least twice SPTM during 4 and 6 years of follow-up, respectively. Their SPTMs have been mild and responded well to corticosteroids just like in the case of MS. The findings highlight the need of searching for serum AQP4-IgG (cell-based assay strongly recommended) in patients with recurrent SPTM and suggest that those patients may have a mild acute attack phase and favorable long-term prognosis.

Background: Few reports describe the influence pregnancy has on the annualized relapse rate (ARR) in neuromyelitis optica spectrum disorder (NMOSD). Objective: To examine pregnancy-related attacks (attacks during pregnancy or within 1 year postpartum) and identify the risk factors for an attack in Japanese NMOSD patients. Methods: We retrospectively reviewed 139 Japanese women whom had aquaporin-4 (AQP4) antibody-positive NMOSD. Among the 114 patients with information, 47 women had 56 pregnancies. We compared the ARR before, during and after pregnancy. Results: Of the 47 NMOSD patients with pregnancy, 22 women (46.8%) had a pregnancy-related attack of the disease (either an onset event or a relapse). The ARR was significantly higher in the first 3 months postpartum (1.80 ± 2.04), than before the pregnancy (0.57 ± 1.16; p = 0.0043) and did not significantly decrease during pregnancy. The ARR before hospitalization and treatment was analyzable in 55 patients without pregnancy and was 1.09 ± 1.17. Among the 11 patients with onset before pregnancy, nine patients had a pregnancy-related attack with a relapse in the previous year, and their immunosuppression was discontinued or made to be at low doses; while the two patients on higher-dose therapies were relapse-free. Conclusion: In the present study, pregnancy-related attack was common in NMOSD, and unlike in multiple sclerosis, the ARR was not reduced during pregnancy. Discontinued or insufficient immunosuppression appeared to increase the risk of pregnancy-related attack.

The relationship between Sjögren’s syndrome (SS) and neuromyelitis optica spectrum disorder (NMOSD) is not completely understood. We report two patients with both conditions and review 47 other previously reported cases meeting currently accepted diagnostic criteria, from 17 articles extracted from PubMed. Out of 44 patients whose gender was informed, 42 were females. Mean age at onset of neurological manifestation was 36.2 years (10-74). Serum anti-AQP4-IgG was positive in 32 patients, borderline in 1, and negative in 4. Our Case 1 was seronegative for AQP4-IgG and had no non-organ-specific autoantibodies other than anti-SSB antibodies. Our Case 2 had serum anti-AQP4, anti-SSA/SSB, anti-thyreoglobulin and anti-acethylcholine-receptor antibodies, as well as clinical hypothyreoidism, but no evidence of myasthenia gravis. Our Cases and others, as previously reported in literature, with similar heterogeneous autoimmune response to aquaporin-4, suggest that SS and NMO co-exist in a common autoimmune milieu which is not dependent on aquaporin-4 autoimmunity.

Background: Neuromyelitis optica spectrum disorder with aquaporin4-immunoglobulin G (NMOSD-AQP4) is an inflammatory disease characterised by a high female predominance. However, the effect of gender in patients with NMOSD-AQP4 has not been fully evaluated. Objective: The aim of this study was to determine the effect of gender in clinical manifestations and prognosis of patients with NMOSD-AQP4. Methods: The demographics, clinical and radiological characteristics, pattern reversal visual evoked potential (VEP) test results, and prognosis of 102 patients (18 males) with NMOSD-AQP4 were assessed. Results: Male patients had a higher age at onset (48.7 vs 41 years, p = 0.037) and less optic neuritis as the onset attack (17% vs 44%, p = 0.026), higher tendency to manifest as isolated myelitis over the follow-up period (67% vs 28%, p = 0.005), fewer optic neuritis attacks per year (0.08 vs 0.27, p < 0.001), and shorter relative P100 latency on VEP testing (97.1% vs 108.3%, p = 0.001). Moreover, male gender was significantly associated with the absence of optic neuritis attacks over the follow-up period independent of their age of onset. Conclusion: In NMOSD-AQP4 patients, gender impacts on disease onset age and site of attack. This may be an important clue in identifying NMOSD-AQP4 patients with limited manifestations as well as in predicting their clinical courses.
