RESUMO
BACKGROUND AND PURPOSE: The aim was to determine the extent of sudomotor dysfunction in people with neuromyelitis optica spectrum disorder (pwNMOSD) and to compare findings with a historical cohort of people with relapsing-remitting multiple sclerosis (pwRRMS). METHODS: Forty-eight pwNMOSD were enrolled from four clinical centers. All participants completed the Composite Autonomic Symptom Score 31 to screen for symptoms of sudomotor dysfunction. Sudomotor function was assessed using the quantitative sudomotor axon reflex test. The results were compared with a historical cohort of 35 pwRRMS matched for age, sex and disease duration. RESULTS: Symptoms of sudomotor dysfunction, defined by a score in the Composite Autonomic Symptom Score 31 secretomotor domain >0, were present in 26 (54%) of pwNMOSD. The quantitative sudomotor axon reflex test confirmed a sudomotor dysfunction in 25 (52.1%) of pwNMOSD; in 14 of them (29.2%) sudomotor dysfunction was moderate or severe. No difference was observed between pwNMOSD and pwRRMS in any of the studied parameters. However, symptomatic sudomotor dysfunction was more frequent in pwNMOSD (n = 8, 22.9%) compared to pwRRMS (n = 1, 3%; p = 0.028). In a multivariable logistic regression analysis, statistically significant predictors for symptomatic sudomotor failure were age and diagnosis of neuromyelitis optica spectrum disorder. CONCLUSIONS: Sudomotor dysfunction is common in pwNMOSD and more often symptomatic compared to pwRRMS.

BACKGROUND: A substantial autonomic nervous system (ANS) dysfunction has been described in multiple sclerosis (MS) and recently, also in neuromyelitis optica spectrum disorder (NMOSD). The prevalence of ANS symptoms contributes to the chronic symptom burden in both diseases. The aim of our study was to assess ANS dysfunction in people with (pw) NMOSD and MS, using the Composite Autonomic Symptom Score-31 (COMPASS-31), and additionally, to evaluate if ANS dysfunction have impact on the quality of life of these patients. METHODS: We conducted cross-sectional study at three national referral neurological clinics in Serbia, Croatia, and Montenegro. A total of 180 consecutive subjects, 80 pwNMOSD and 100 pwMS, followed-up at these clinics, were enrolled in the study. Subjects included in the study completed: the validated versions of the COMPASS-31 and the Multiple Sclerosis Quality of Life-54 (MSQoL-54), and the Beck Depression Inventory (BDI). RESULTS: This study demonstrated that the total COMPASS-31 score > 0.0, implicating the presence of ANS dysfunction, was detected in almost all NMOSD and MS study participants tested (80/80, and 97/100, respectively). Our findings showed that autonomic symptom burden was statistically significantly correlated with decreased quality of life, in both NMOSD and MS cohorts. The independent predictors of the better quality of life in pwNMOSD were lower autonomic burden, particularly the absence of the orthostatic intolerance (p = 0.005), along with lower EDSS and BDI score (p ≤ 0.001). Similarly, in pwMS, independent predictors were EDSS, BDI, orthostatic intolerance, and the total COMPASS-31 (p ≤ 0.001). CONCLUSION: Our study demonstrated that a significant proportion of persons with both NMOSD and MS have considerable dysautonomic symptom burden which is correlated with the decreased quality of life. Further investigations are warranted in order to optimize treatment interventions in MS and NMOSD.

Introduction: The health-related quality of life (HRQoL) of people with (Pw) multiple sclerosis (MS) is usually deteriorated. It has been recently suggested that comorbidities may have the negative influence on the quality of life of the PwMS, but according to the best of our knowledge, only one study investigated, although in a very small cohort, the impact of individual comorbidity on the quality of life of PwMS. The aim of our investigation was to assess, in an international, multicentric study, the impact of comorbid seizure/epilepsy on the HRQoL in PwMS. Methods: We conducted cross-sectional study at numerous neurological centers in Serbia, Croatia, Bulgaria, Montenegro, Northern Macedonia, and Bosnia and Herzegovina (Federation of Bosnia and Herzegovina and Republic of Srpska). For each patient, demographic and clinical data were collected, including Expanded disability status scale (EDSS) score. Beck Depression Inventory (BDI) and the 36-Item Short Form Health Survey (SF-36) questionnaires were administered to all patients. Results: The study comprised 326 PwMS in total, 127 PwMS with seizure/epilepsy and 209 PwMS without. Both mean Physical health composite (PHC) and mental health composite (MHC) scores, were statistically significantly higher in PwMS without seizure/epilepsy, implicating worse quality of life in PwMS with comorbid seizure/epilepsy. Presence of seizure/epilepsy in pwMS was statistically significant independent predictor of both PHC and MHC, in multivariate linear regression model after adjustment for potential confounding variables. The hierarchical multivariate regression analysis was performed in order to establish the most important predictors of the PHC and MHC of the SF-36, in PwMS with seizure/epilepsy; older age, higher level of disability, as measured by EDSS, higher depression score, drug-resistant epilepsy and shorter time since last seizure were found to significantly predict worse MHC score in PwMS with seizure/epilepsy. Discussion: Our results point to the possible role of theinterventions related to the adequate control of epilepsy along with improvement of the mental health status to be important in order to reduce MS burden in the PwMS with comorbid seizure/epilepsy.

BACKGROUND: Reports on outcomes of COVID-19 in patients with neuromyelitis optica spectrum disorder (NMOSD) are scarce, as well as those related to the safety profile of the vaccines in this population. The aim of this survey is to present demographic and clinical characteristics of patients with NMOSD who developed COVID-19 and safety data of the COVID-19 vaccines in these persons. METHODS: This study comprise all patients from the Hospital registry of NMOSD, of the Clinic of Neurology in Belgrade, who fulfilled the 2015 NMOSD diagnostic criteria, and who after invitation by phone call, from April 10 to May 10, 2021, accepted to participate and provide information regarding COVID-19 and vaccination against Sars-CoV-2 (n = 53). RESULTS: Sixteen out of 53 enrolled NMOSD patients were diagnosed with COVID-19. In three cases (18.8%), severity of COVID-19 clinical manifestations warranted hospitalization, and one of these patients, died due to COVID-19 (case fatality ratio = 6.25%), after invasive mechanical ventilation. The remaining two patients had grade II COVID -19 severity and were hospitalized because of pneumonia, not requiring supplemental oxygen. Median EDSS in patients requiring hospitalization was 4.5, and in the non-hospitalized group, it was 3.0. Nine out of 53 patients received two doses of vaccine against Sars-Cov-2 (8 Sinopharm and one Pfizer). Pain at the site of application was the only vaccine-related adverse effect. CONCLUSIONS: Our survey indicates overall favourable COVID-19 outcome and encouraging safety profile of the vaccines in persons with NMOSD, in our cohort. Prospective studies are warranted to confirm these data.

The aim of this study was to evaluate the humoral response to the SARS-CoV-2 infection and vaccination in the NMOSD patients, treated with various immunosuppresants (ISs). Serum IgG against the complete sequence of the receptor binding domain of the spike protein was measured using ELISA SARS-CoV-2 IgG, INEP, Belgrade. Seroconversion occurred in 8/10 patients with COVID-19, and in 5/9 after vaccination. One out of four patients treated with inebilizumab seroconverted (after COVID-19); antibodies were not detected in any of the remaining 3 patients who were vaccinated. Antibodies developed after COVID-19 in 4/5 patients treated with azathioprine and all treated with mycophenolate-mofetil, and after vaccination, in 5/6 patients treated with these ISs. Post-vaccination humoral response was impaired in our NMOSD patients treated with B-cell depleting therapies; seroconversion occurred in almost all patients treated with conventional synthetic disease modifying ISs.
