We aimed to examine treatment interventions implemented in patients experiencing neuromyelitis optica spectrum disorders (NMOSD) attacks (frequency, types, and response)., Methods: Retrospective study. Data on patient demographic, clinical and radiological findings, and administered treatments were collected. Remission status (complete [CR], partial [PR], no remission [NR]), based on changes in the EDSS score was evaluated before treatment, during attack, and at 6 months. CR was analyzed with a generalized estimating equations (GEEs) model., Results: A total of 131 patients (120 NMOSD and 11 myelin oligodendrocyte glycoprotein-antibody-associated diseases [MOGAD]), experiencing 262 NMOSD-related attacks and receiving 270 treatments were included. High-dose steroids (81.4%) was the most frequent treatment followed by plasmapheresis (15.5%). CR from attacks was observed in 47% (105/223) of all treated patients. During the first attack, we observed CR:71.2%, PR:16.3% and NR:12.5% after the first course of treatment. For second, third, fourth, and fifth attacks, CR was observed in 31.1%, 10.7%, 27.3%, and 33.3%, respectively. Remission rates were higher for optic neuritis vs. myelitis (p < 0.001). Predictor of CR in multivariate GEE analysis was age in both NMOSD (OR = 2.27, p = 0.002) and MOGAD (OR = 1.53, p = 0.03)., Conclusions: This study suggests individualization of treatment according to age and attack manifestation. The outcome of attacks was generally poor., (© The Author(s) 2021.)

Background: The purpose of this study was to assess family planning (FP) among women with multiple sclerosis (WwMS)., Methods: We invited 604 WwMS to answer a survey focused on FP: a) Temporal relationship between pregnancy and the diagnosis of multiple sclerosis; b) History of FP; c) Childbearing desire; d) Information on family planning. Comparisons between pregnancy and not pregnancy after MS, as well as, planned and unplanned pregnancy were analyzed. Multivariate and univariate analyses were used to assess the impact of independent variables and FP., Result: 428 (71.7%) WwMS completed the survey. A 19.1% got pregnant after MS diagnosis and we evaluated FP in the last pregnancy, 56.1% patients had a planned pregnancy. Professional addressing FP (OR = 0.27, 95%-CI 0.08-0.92, p = 0.03) and non-injection drug treatment before pregnancy (OR = 2.88, 95%-CI 1.01-8.21, p = 0.047) were independent predictors of unplanned pregnancy in our multivariate model. Among WwMS ≤ 40 years, 48.7% had future childbearing desire. Young age (p < 0.001), PDDS <3 (p = 0.018), disease duration <5 years (p = 0.02), not childbearing before MS diagnosis (p < 0.001) and neurologist addressing family planning (p = 0.01) were significantly associated with childbearing desire., Conclusions: This research highlights that pregnancy remains an important concern among WwMS., (© The Author(s) 2021.)

Background: Restless legs syndrome (RLS) frequency, and its association with depression, anxiety, sleep disorders, and fatigue, has not been previously studied in Latin American patients with multiple sclerosis (MS). We aimed to assess RLS frequency in patients with MS living in Argentina and to examine potential associations with depression, anxiety, and sleep disorders., Methods: A cross-sectional study (n = 427) was conducted using a self-administered questionnaire, including International RLS Study Group criteria, to compare RLS frequency in patients with MS versus controls. The Hospital Anxiety and Depression Scale and the Fatigue Severity Scale were administered to all participants. Insomnia, excessive daytime somnolence, and other risk factors in patients with MS with RLS were analyzed using logistic regression., Results: We included 189 patients with definite MS and 238 controls. The RLS frequency was 29.1% in patients with MS versus 13.0% in controls (odds ratio [OR] = 2.74, P = .00005). Moreover, clinically significant RLS (csRLS; ie, symptoms present ≥2 days per week) frequency was 19.4% in patients with MS versus 4.2% in controls (OR = 5.37, P < .00001). Longer MS duration and presence of anxiety, depression, insomnia, and smoking cigarettes were all significantly associated with RLS. Multivariate analysis showed that anxiety and fatigue were significantly associated with MS with RLS and MS with csRLS., Conclusions: Both RLS and csRLS showed strong association with MS, supporting the need to screen for anxiety/depression, sleep quality, and fatigue in this patient population. We believe that identifying the presence and severity of these conditions would contribute to better MS management and treatment., Competing Interests: The authors declare no conflicts of interest.
