Abstract
PURPOSE To validate and culturally adapt the Sexual Health Inventory for Men (IIEF-5) and the Premature Ejaculation Diagnostic Tool (PEDT), to compare the frequency and severity of erectile dysfunction (ED) and premature ejaculation (PE) in male individuals with MS (mwMS) in comparison with healthy controls (HC) and to investigate predictors of the severity of ED and PE in mwMS. METHODS 216 consecutive mwMS and 37 HC completed IIEF-5 and PEDT. Additionally, 114 mwMS completed the Modified Fatigue Impact Scale (MFIS), Beck Depression Inventory (BDI-2), Composite Autonomic System Score-31 (COMPASS-31), and the 5-level EQ-5D questionnaire. RESULTS The test-retest reliability was satisfactory for both questionnaires, with acceptable reliability for both questionnaires. mwMS scored less on IIEF-5 compared to HC (23, IQR 18.25-25 vs 24, IQR 20.25-25, p = 0.028). ED was present in 39.4 % of mwMS and 27.8 % of HC (p = 0.198). Definite PE was present in 12.1 %, and possible PE in 7.8 % of mwMS; and 5.6 % and 11.1 % of HC respectively (p = 0.496). An increase in EDSS was a positive predictor (Exp(B) 1.455, 95 %CI 1.135-1.886, p = 0.003) and the presence of cremasteric reflex was a negative predictor (Exp(B) 0.381, 95 %CI 0.183-0.790, p = 0.010) for the presence of ED. For the PE, disease duration was the only positive predictor in a univariable logistic regression (Exp(B) 1.084, 95 %CI 1.019-1.153, p = 0.070). CONCLUSION SD is frequent in mwMS with EDSS being a positive and the presence of cremasteric reflex a negative predictor of ED and disease duration a positive predictor of PE symptoms.

Abstract
OBJECTIVE To determine the COVID-19 vaccine uptake among people with multiple sclerosis (pwMS) compared to the general population in Croatia. METHODS Data from all pwMS entered in the MS Base register until March 24th, 2022 were extracted including age, sex, MS phenotype, disease-modifying therapy (DMT), and date of COVID-19 vaccination. Data on the general population of Croatia were obtained from the vaccination register of the Croatian Institute of Public Health. RESULTS 64.4% pwMS were fully COVID-19 vaccinated which was comparable to 66.3% of the general population. More pwMS were fully vaccinated in the age group 20-24 (74.1% vs 51.7%), and fewer pwMS were fully vaccinated in the age group 65-69 (33.3% vs 80.4%) compared to the general population of the same age group, respectively. PwMS who received at least one dose of any COVID-19 vaccine were older (40.5 vs 37.6 years, p = 0.01), had higher EDSS (2.0 vs 1.0, p = 0.025), and had longer disease duration (6.39 vs 5.35 years, p = 0.02), were more likely to have progressive disease course (p = 0.049) and were on high efficacy DMTs (p = 0.045) compared to unvaccinated pwMS. Longer disease duration positively predicted vaccine uptake. CONCLUSION Croatia has suboptimal COVID-19 vaccination uptake without a significant difference between the general population and pwMS.

Abstract
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.

Abstract
BACKGROUND Cladribine is an oral disease-modifying drug authorized by the European Medicine Agency for the treatment of highly active relapsing multiple sclerosis (MS). OBJECTIVES To provide real-world evidence of cladribine's effectiveness and safety in people with MS (pwMS). METHODS A retrospective observational multi-center, multi-national study of pwMS who were started on cladribine tablets in ten centers from five European countries. RESULTS We identified 320 pwMS treated with cladribine tablets. The most common comorbidities were arterial hypertension and depression. Three patients had resolved hepatitis B infection, while eight had positive Quantiferon test prior to cladribine commencement. There were six pwMS who had malignant diseases, but all were non-active. During year 1, 91.6% pwMS did not have EDSS worsening, 86.9% were relapse-free and 72.9% did not have MRI activity. During the second year, 90.2% did not experience EDSS worsening, 86.5% were relapse-free and 75.5% did not have MRI activity. NEDA-3 was present in 58.0% pwMS in year 1 and in 54.2% in year 2. In a multivariable logistic regression model age positively predicted NEDA-3 in year 1. The most common adverse events were infections and skin-related adverse events. Lymphopenia was noted in 54.7% of pwMS at month 2 and in 35.0% at month 6. Two pwMS had a newly discovered malignant disease, one breast cancer, and one melanoma, during the first year of treatment. CONCLUSION Our real-world data on the effectiveness and safety of cladribine tablets are comparable to the pivotal study and other real-world data with no new safety signals.

Abstract
BACKGROUND We evaluated the influence of symptoms of depression, anxiety, and stress on the results of COMPASS-31 in a large population of people referred to the head-up tilt test (HUTT) and healthy controls (HC). METHODS Nine hundred fifty-nine consecutive patients referred to HUTT and 518 HC were enrolled. All participants completed Composite Autonomic Symptom Score-31 (COMPASS-31). Stress symptoms were evaluated by Depression, Anxiety, and Stress-21 (DASS-21) questionnaire. We corrected the result of the COMPASS-31 with the independent predictors in order to improve the specificity of the test. RESULTS In both patients and HC, COMPASS-31 was higher in participants with depression, anxiety, and stress symptoms (all p < 0.001). In a multivariable linear regression analysis, HC was negative, while female sex and symptoms of depression, anxiety, and stress were independent positive predictors of COMPASS-31. In HC, COMPASS-31 had a median of 7.913, and this value differentiated between HC and patients with a high sensitivity of 87% and low specificity of 50%. In order to adjust the value of COMPASS-31 with the parameters that were significant in the multivariable linear regression model, we calculated the new corrected COMAPSS-31 (cCOMPASS-31), which had comparable sensitivity of 77%, but an increased specificity of 73%. CONCLUSION This study has shown that symptoms of depression, anxiety, and/or stress worsen the perceived severity of autonomic symptoms in people with symptoms of orthostatic intolerance and healthy population. cCOMPASS-31 is a valuable tool that can help clinicians in discerning the true autonomic background of patients' complaints.

Abstract
After 2 weeks of treatment, a woman with multiple sclerosis treated with dimethyl fumarate developed alopecia. Considering the adverse events, the therapy was discontinued, leading to alopecia regression during the next 3 months. Although the precise mechanism has not been completely elucidated, glutathione depletion or downregulation of aerobic glycolysis are considered to be potential reasons for hair loss induction. The incidence and mechanism of this uncommon adverse reaction to dimethyl fumarate should be further investigated.

Abstract
Autonomic dysfunction (AD) in people with MS (pwMS) is a frequent finding. This narrative review will present an overview of central neural mechanisms involved in the control of cardiovascular and thermoregulatory systems, and methods of autonomic nervous system testing will be discussed thereafter. Since the need for standardization of autonomic nervous system (ANS) testing, we will focus on the standard battery of tests (blood pressure and heart rate response to Valsalva maneuver and head-up tilt, and heart rate response to deep breathing test plus one of the tests for sudomotor function), which can detect ANS pathology in the majority of pwMS. The review will briefly discuss the other types of AD in pwMS and the use of appropriate tests. While performing ANS testing in pwMS one has to consider the multiple sclerosis phenotypes, disease duration, and its activity, the degree of clinical disability of patients included in the study, and the disease-modifying therapies taken, as these factors may have a great influence on the results of ANS testing. In other words, detailed patient characteristics presentation and patient stratification are beneficial when reporting results of ANS testing in pwMS.

Abstract
INTRODUCTION We aimed to provide insights into transverse myelitis (TM) following COVID-19 by analyzing cases treated at tertiary care neurology centers and a systemic review of the literature. METHODS The retrospective observational multi-center study was conducted at the four university neurology departments in Croatia, Slovenia, Serbia, and Austria. We searched for acute myelitis cases that occurred during or after COVID-19. A systemic review of the literature on COVID-19 and transverse myelitis was performed. RESULTS We identified 76 persons with TM associated with COVID-19, 13 from the multi-center study and 63 from the literature review. Most of the participants (55.6%) had an intermediate latency, 25.4% had short and 19% long latency from COVID-19 symptoms to TM. The clinical presentation consisted of the typical TM signs. More than half of the participants had inflammatory changes in the CSF, with rare patients having intrathecal OCB synthesis and positive serology for anti-MOG or anti-AQP4 antibodies. Persons with autonomic symptoms and CSF pleocytosis were significantly more common to have an intermediate latency of 8 to 21 days from COVID-19 to TM (p = 0.005 and p = 0.003; respectively). According to logistic regression analysis, only participants with lesions evident on spinal cord MRI compared to normal spinal cord MRI had reduced risks for poor recovery. >80% of participants were treated with a combination of corticosteroids and intravenous immunoglobulins or plasma exchange with 73% having incomplete recovery. CONCLUSION Our study further characterizes clinical, laboratory, and MRI features, as well as treatment of TM associated with COVID-19.

Abstract
OBJECTIVES To investigate differences in beat-to-beat systolic blood pressure variability (SBPV) in people with secondary progressive MS (pwSPMS), clinically isolated syndrome (pwCIS) and healthy controls (HC). METHODS This retrospective case-control study included 46 pwSPMS, 46 pwCIS and 44 HC. A semi-automated software made with MATLAB R2019b (The MathWorks, Inc.) was used for the evaluation of SBPV. The frequency domain characteristics observed were the power spectrum in the LF and HF bands and the LF/HF ratio. Data is expressed in absolute power (mmHg2) of LF and HF and ratio (LF/HF) during both supine and tilt-up phases of testing. RESULTS There were no significant differences in mean systolic (sBP) or diastolic blood pressure (dBP) values during supine and tilt-up phases of testing between groups. During the supine phase of testing LF and LF/HF were significantly lower in the SPMS group (4.17±5.38 and 3.52±2.34, respectively) compared to the CIS (5.42±3.59, p = 0.015 and 5.92±4.63, p = 0.029, respectively) and HC group (6.03±4.55, p = 0.011 and 6.52 ± 5.09, p = 0.010, respectively), while during the tilt-up phase, LF was significantly lower compared to both the CIS and HC group, and HF was significantly lower only compared to the CIS group. CONCLUSION SBPV is altered in pwSPMS compared to pwCIS and normal controls. Further research in the field of MS related dysautonomia is warranted not only because of its relevance to comorbidities and MS symptoms, but also because of its likely involvement in the pathophysiology of MS.

Abstract
Coronavirus disease 2019 (COVID-19) vaccines have been reported as possible triggers of the production of antibodies pathogenic to the peripheral nerve and neuromuscular junction. We report on a patient who experienced vertical diplopia three weeks after the booster dose of the Pfizer-BioNTech vaccine (Comirnaty®). The diagnosis of myasthenia gravis (MG) was established based on highly positive antibodies to the nicotinic acetylcholine receptor (nAChR). Treatment with pyridostigmine and prednisone was started with gradually raising doses. On a follow-up exam two months after treatment initiation, clinical improvement was noted with an almost normal bulbomotor examination. The occurrence of diplopia following COVID-19 vaccination should raise suspicion of new-onset ocular MG and testing for anti-nAChR antibodies is advised.

Abstract
OBJECTIVES The aim of this study was to investigate the short- and long-term effects of siponimod on autonomic nervous system (ANS) function, in people with secondary progressive multiple sclerosis (pwSPMS) METHODS: The following ANS tests were performed in 26 pwSPMS: a 10 min supine resting position, Valsalva maneuver, deep breathing test and a 10 min tilt-up table test. Heart rate variability (HRV) was performed for the 10 min in supine resting position (M0) and for a 3 h period after siponimod treatment initiation (M0s1-6). All ANS tests were repeated after at least 6 months of treatment with siponimod (M6). RESULTS In all 6 intervals after siponimod ingestion (M0s1-6), standard deviation of NN intervals (SDNN) was higher compared to M0. After 6 months of continuous treatment with siponimod, SDNN was significantly lower compared to M0. At M6, Valsalva ratio and respiratory sinus arrhythmia were lower compared to M0 values (1.510±0.338 vs 1.864±0.456, p=0.003 and 7.969±2.865 vs 13.091±4.687, p<0.001, respectively). Cardiovagal index was significantly higher at M6 compared to M0 (1 (range 0-2) vs 0 (range 0-1), p=0.008, respectively). Active Magnetic Resonance Imaging (MRI) one year prior to starting siponimod was a positive predictor of M6 SDNN and Adrenergic Index (AI) at M0 was a negative predictor of M6 SDNN. CONCLUSION This study has shown an inverse relationship in short- versus long-term effects of siponimod on ANS function. A shift towards parasympathetic predominance was observed during the first three hours after ingestion, while after 6 or more months of continuous treatment with siponimod, a shift towards sympathetic predominance was observed.

Abstract
Objective To determine the influence of immunoglobulins (Ig) level on the rate of infections in people with multiple sclerosis (pwMS) treated with ocrelizumab. Methods We enrolled 109 consecutive pwMS treated with ocrelizumab with a mean follow-up of 2.69±0.56 (1.36-4.27) years. We have retrospectively searched our electronic database and the following information was collected: age, sex, MS characteristics, number of ocrelizumab cycles, infections, duration of the infection, hospitalization due to infection, treatment of the infection, and COVID-19 characteristics. Ig levels were measured within 14 days before each ocrelizumab infusion. Results Number of pwMS with values of IgM and IgG below lower level of normal at baseline was 3 (2.8%) and 2 (2.8%), respectively; and before 6th cycle of ocrelizumab 5 (13.5%) and 5 (13.5%), respectively. Levels of IgM were steadily decreasing over time, while levels of IgG started to show statistically significant drop only after 5th cycle of ocrelizumab. 58.7% pwMS experienced infection during treatment, with a median number of infections per pwMS being 1, range 0-4. Female sex increased the risk of any infection (HR 2.561, 95%CI 1.382-4.774, p=0.003). Higher age and smaller drop in IgM before 3rd ocrelizumab cycle increased the risk for infection requiring hospitalization (HR 1.086, 95%CI 1.018-1.159, p=0.013 and HR 9.216, 95%CI 1.124-75.558, p=0.039, respectively). Longer disease duration increased the risk for COVID-19 (HR 1.075, 95%CI 1.002-1.154, p=0.045). Conclusion The present findings broaden limited real-world data on infection and COVID-19 risk in pwMS treated with ocrelizumab.

Abstract
Objectives To determine anti-SARS-Cov2 antibodies and T-cell immunity in convalescent people with multiple sclerosis (pwMS) and/or pwMS vaccinated against Covid-19, depending on the disease modifying therapy, and in comparison to healthy controls (HC). Methods 75 participants were enrolled: Group 1—29 (38.7%) COVID-19 convalescent participants; Group 2—34 (45.3%) COVID-19 vaccinated; Group 3—12 (16.0%) COVID-19 convalescent participants who were later vaccinated against COVID-19. Cellular immunity was evaluated by determination of number of CD4+ and CD8+ cells secreting TNFα, IFNγ, and IL2 after stimulation with SARS-CoV-2 peptides. Results pwMS treated with ocrelizumab were less likely to develop humoral immunity after COVID-19 recovery or vaccination. No difference was observed in the cellular immunity in all studied parameters between pwMS treated with ocrelizumab compared to HC or pwMS who were treatment naïve or on first line therapies. These findings were consistent in convalescent, vaccinated, and convalescent+vaccinated participants. COVID-19 vaccinated convalescent pwMS on ocrelizumab compared to COVID-19 convalescent HC who were vaccinated did not show statistically difference in the rate of seroconversion nor titers of SARS-CoV-2 antibodies. Conclusion Presence of cellular immunity in pwMS on B-cell depleting therapies is reassuring, as at least partial protection from more severe COVID-19 outcomes can be expected.

Abstract
Introduction Alemtuzumab is highly effective in the treatment of patients with relapsing multiple sclerosis (PwRMS) and selectively targets the CD52 antigen, with a consequent profound lymphopenia, particularly of CD4+ T lymphocytes. However, the immunological basis of its long-term efficacy has not been clearly elucidated. Methods We followed up 29 alemtuzumab-treated RMS patients over a period of 72 months and studied the immunological reconstitution of their CD4+ T cell subsets by means of phenotypic and functional analysis and through mRNA-related molecule expression, comparing them to healthy subject (HS) values (rate 2:1). Results In patients receiving only two-course alemtuzumab, the percentage of CD4+ lymphocytes decreased and returned to basal levels only at month 48. Immune reconstitution of the CD4+ subsets was characterized by a significant increase (p < 0.001) in Treg cell percentage at month 24, when compared to baseline, and was accompanied by restoration of the Treg suppressor function that increased within a range from 2- to 6.5-fold compared to baseline and that persisted through to the end of the follow-up. Furthermore, a significant decrease in self-reactive myelin basic protein-specific Th17 (p < 0.0001) and Th1 (p < 0.05) cells reaching HS values was observed starting from month 12. There was a change in mRNA of cytokines, chemokines, and transcriptional factors related to Th17, Th1, and Treg cell subset changes, consequently suggesting a shift toward immunoregulation and a reduction of T cell recruitment to the central nervous system. Conclusions These data provide further insight into the mechanism that could contribute to the long-term 6-year persistence of the clinical effect of alemtuzumab on RMS disease activity.

Objectives To report clinical outcome, development of humoral and T-cell mediated immunity in convalescent COVID-19 people with multiple sclerosis (pwMS) treated with ofatumumab in the ALITHIOS study from a single center. Methods Testing for SARS-Cov2 IgG antibodies was performed on two occasions with at least three months apart between the two testing. During the second antibody testing, interferon-γ ELISpot was used to assess cellular immunity. Results All four subjects had mild COVID-19 infection without any sequelae. In all subjects except subject 2, COVID-19 was confirmed with PCR. Subjects 1, 2 and 4 had normal levels of IgM and IgG without measurable counts of CD19 cells prior to COVID-19. Subject 3 administered the last dose of ofatumumab 24 days prior to COVID-19 symptoms, but had a gap of 28 weeks of ofatumumab application beforehand due to low IgM levels. Subject 4 received COVID-19 vaccinations before second testing, so second testing and T-cell immunity testing were not performed. Subjects who were CD19 depleted did not had measurable levels of SARS-Cov2 IgG antibodies. Subject 3 had first and second SARS-COV2 titer of 118 U/ml and > 250 U/ml, respectively. All three pwMS showed T cell immunity against SARS-CoV-2. Quotient of basal spots divided by interferon-γ secreting spot forming units were 4, 8 and 14.7 SI in subjects 1, 2 and 3, respectively (>3 considered reactive). Conclusion While no antibody response was observed in pwMS who were CD19+ lymphocyte depleted, T cell immunity against SARS-CoV-2 was observed in all three pwMS treated with ofatumumab.

Abstract
Introduction Miller Fisher syndrome (MFS) is a rare variant of Guillain-Barre syndrome characterized by ataxia, areflexia, and ophthalmoplegia. We present a case of MFS following Pfizer COVID-19 vaccine. Case presentation A previously healthy 24-year-old female presented with binocular horizontal diplopia 18 days after receiving the first dose of Pfizer COVID-19 vaccine (Comirnaty®). Anti-ganglioside testing revealed positive anti-GQ1b antibodies. Intravenous immunoglobulins were administered, in a dose of 2 g per kg of body weight over 5 days. On a follow-up exam 3 weeks after the treatment, clinical improvement was noted with normal bulbomotor examination. Conclusion Patients with acute ophthalmoplegia occurring after COVID-19 vaccination should be screened for the presence of anti-GQ1b antibody. If the antibody is present, intravenous immunoglobulin should be administered as it may hasten clinical improvement. Supplementary Information The online version contains supplementary material available at 10.1007/s10072-021-05776-0.

Abstract
INTRODUCTION Multiple sclerosis (MS) is a chronic demyelinating immune mediated disease of the central nervous system. Autonomic dysfunction (AD) is frequently present in persons with MS (pwMS) and increases with disease duration and progression. AREAS COVERED Cardiovascular, genitourinary, and sudomotor autonomic dysfunction in pwMS are reviewed and managing of these disorders is addressed. EXPERT OPINION AD in pwMS can manifest with a myriad of symptoms including cardiovascular, urogenital, and sweating disorders. These symptoms can significantly impact the quality of life of pwMS with poor tolerance of upright position, difficulties in sexual function, and low endurance of physical activity especially in warm environments. Health professionals involved in care of pwMS should possess basic knowledge of the function of the autonomic nervous system and be informed of the way disorders of the autonomic function may manifest in pwMS in order to provide the proper care.

Abstract
BACKGROUND AND PURPOSE Alemtuzumab, a monoclonal anti-CD52 antibody, and cladribine, a purine nucleoside analogue, are used for the treatment of highly active relapsing-remitting multiple sclerosis (MS). Both are administered as two short yearly courses but possess the ability to induce long-term remission, labeling them as immune reconstitution therapies. Although disease activity after alemtuzumab administration is rare, there are a small number of people with MS who will experience disease activity despite repeated alemtuzumab treatment. METHODS We report on six patients with MS who experienced disease activity after alemtuzumab and were subsequently treated with cladribine and followed up for up to 2 years. RESULTS None of the patients experienced relapses during the follow-up period and in all patients Expanded Disability Status Scale values remained unchanged. All patients had lymphopenia at one time point. In patients 1 and 2, at the nadir, the lymphopenia was grade 1, in patient 3 it was grade 2 and in patients 5 and 6 it was grade 3. No infections or malignancies were recorded during the follow-up. CONCLUSION This report provides a framework for treating people with MS with sequential immune reconstitution therapies.

Abstract
Traditionally, the management of active relapsing remitting MS was based on the, so-called, maintenance therapy, which is characterized by continuous treatment with particular disease modifying therapy (DMT), and a return of disease activity when the drug is discontinued. Another approach is characterized by a short treatment course of a DMT, which is hypothesized to act as an immune reconstitution therapy (IRT), with the potential to protect against relapses for years after a short course of treatment. Introduction of monoclonal antibodies in the treatment of MS has revolutionized MS treatment in the last decade. However, given the increasingly complex landscape of DMTs approved for MS, people with MS and neurologists are constantly faced with the question which DMT is the most appropriate for the given patient, a question we still do not have an answer to. In this product review, we will discuss the first DMT that acts as IRT, an anti-CD52 monoclonal antibody alemtuzumab and an anti CD20 monoclonal antibody, ocrelizumab that has the potential to act as an IRT, but is administered continuously. Special emphasis will be given on safety in the context of COVID-19 pandemics and vaccination strategies.

Abstract
Aim To determine the influence of high-efficacy disease modifying therapy (DMT) on the development of IgG SARS-CoV-2 antibody response in COVID-19 convalescent people with multiple sclerosis (pwMS). Methods Seventy-four pwMS taking high-efficacy DMTs (specifically natalizumab, fingolimod, alemtuzumab, ocrelizumab, cladribine and ublituximab) and diagnosed with COVID-19 and 44 healthy persons (HC) were enrolled. SARS-CoV2 antibodies were tested with Elecsys® Anti-SARSCoV-2 S assay. Results pwMS taking high-efficacy DMTs had a significantly higher chance of having negative titer of SARS-CoV2 antibodies compared to healthy controls (33 negative pwMS [44.6%] compared to one negative HC [2.3%], p < 0.001). pwMS taking B-cell depleting therapy (ocrelizumab and ublituximab) had a significantly higher chance of having negative titer of SARS-CoV2 antibodies compared to pwMS on all other DMTs (29 negative pwMS on B-cell therapy [64.4%] compared to four negative pwMS on all other DMTs [13.8%], p < 0.001). Out of other DMTs, two (33.3%) pwMS taking fingolimod and two (16.7%) pwMS taking cladribine failed to develop IgG SARS-COV-2 antibodies. B-cell depleting therapy independently predicted negative titer of IgG SARS-CoV-2 antibody (Exp[B] =0.014, 95%CI 0.002–0.110, p < 0.001). Conclusions A significant proportion of convalescent COVID-19 pwMS on high-efficacy DMTs will not develop IgG SARS-CoV-2 antibodies. B-cell depleting therapies independently predict negative and low titer of IgG SARS-CoV-2 antibody.

Abstract
OBJECTIVE So far, a limited number of real-world evidence studies about the effectiveness and safety of alemtuzumab (ALM) have been published, some of them with a relatively small number of included patients. We aimed to study the efficacy and safety of ALM in real-world clinical practice in two MS centers in Slovenia and Croatia. METHODS This was a retrospective chart review of 71 consecutive patients with relapsing-remitting MS who were treated with ALM from 2015 till 2018. The following data were collected: gender, age at disease onset, disease duration at ALM initiation, previous disease modifying therapy, number of relapses, active MRI lesions, and EDSS in the year prior to ALM initiation and every year of follow-up. RESULTS All patients completed the standard dosing schedule and were followed for a mean time of 3.2±1.1 years after the initiation of treatment. Complete data for the 2 years after treatment (relapses, EDSS, and MRI) were available for 48 patients, of which 14 (29.2%) achieved NEDA. Clinical NEDA was achieved in 38 out of 63 participants (60.3%). In year 1, 24 out of 57 (42.1%) patients achieved NEDA. In year 2, 26 out of 41 (63.4%) patients achieved NEDA. Lower EDSS prior to starting ALM was the only independent predictor of NEDA in a multivariable model. Adverse events occurred in 58 participants (84.1%), with no new safety signals identified. CONCLUSION According to the data from our cohort of early active RRMS patients we conclude ALM efficacy remains high in the real-world clinical practice.

Abstract
Background We investigated whether the results of autonomic function tests correlate with body composition and shape in healthy young people. Methods We conducted cardiovascular reflex tests (heart rate [HR] and blood pressure [BP] responses to the Valsalva maneuver and HR response to deep breathing) and the tilt table test with 32 subjects (19 males; mean age, 22.1±1.9 years). Participants also completed an anthropometric measurement sequence (weight; height; upper arm, hips, and waist circumference; triceps and subscapular skinfold), bioelectric impedance testing, and hand grip strength measurements. Results Markers of obesity, other anthropometric measures, functional measures, and the basal metabolic rate (BMR) were significantly positively correlated with systolic BP (SBP) and diastolic BP (DBP) in both the supine and tilted positions. There was a positive correlation between the difference in HR (ΔHR) between the tilt and supine body positions and markers of obesity, the functional marker of dominant handgrip strength, and BMR. Participants with a body mass index (BMI) <25 kg/m2 had significantly lower median values of ΔHR, DBP in the tilt-test, SBP at rest, and SBP in the tilt-test than participants who had a BMI ≥25 kg/m2 (10.55 vs. 21.95 bpm, P=0.003; 77.55 vs. 90.05 mmHg, P=0.045; 113.45 vs. 140.55 mmHg, P=0.013; 117.00 vs. 135.25 mmHg, P=0.006, respectively). Body fat percentage was identified as an independent positive predictor (β=0.993; 95% confidence interval [CI], 0.070 to 1.916; P=0.036) and body water percentage was an independent negative predictor of tilted SBP (β=-1.370; 95% CI, -2.634 to 0.106; P=0.035). Conclusion High sympathetic activity, as evaluated by cardiovascular regulation, correlates with a high share of adipose tissue in young healthy persons.

Abstract
A significant deterioration of the trigeminal sensory pathway function occurs in pwMS. Cervical spinal cord lesions were negative predictor of tSSEP improvement. There is a moderate to high correlation between ordinal and quantitative tSSEP scores calculations.
Introduction The aim of the present study was to investigate the long-term evolution of tongue somatosensory evoked potentials (tSSEP) in people with multiple sclerosis (pwMS). Methods Out of initial 121 participants, after two-year follow-up, the data were available for 74 and after four-year follow-up for 58 pwMS. In all pwMS complete neurological examination, brain MRI, cervical spinal cord MRI (if available) and tSSEP were performed at baseline visit (M0). Complete neurological examination and tSSEP were performed 2 and 4 years later (M24 and M48). tSSEP results were interpreted in the form of ordinal tSSEP score and quantitative tSSEP zscore calculated from the sum of z-transformed tSSEP latencies. Results Differences in tSSEP scores and tSSEP zscores in three different timepoints showed significant worsening of both scores over time. For the tSSEP score the difference was significant for M0-M24 and M0-M48 visits, but not for M24-M48 visits. For the tSSEP zscore the difference was significant for M0-M48 and M24-M48 visits, but not for M0-M24 visits. The only significant negative predictor found for the tSSEP score improvement was presence of cervical spinal cord lesions on the MRI. A moderate to high correlation was observed between both forms of tSSEP score at all three timepoints. Conclusion This study demonstrates a significant deterioration of trigeminal sensory pathway in MS over time, giving further insight into trigeminal system damage in pwMS.

Abstract
The aim of this study was to evaluate clinical and neurophysiological characteristics of Persistent postural-perceptual dizziness (PPPD) in a tertiary vertigo clinic. This was a cross-sectional study that included consecutive patients examined in the Vertigo clinic of the University Hospital Center Zagreb, Croatia. The following data were extracted from the electronic hospital records: age, sex, the duration of symptoms, initial trigger event, results of the caloric testing, video head impulse test (vHIT) for all six semicircular canals and ocular and cervical vestibular evoked myogenic potentials (oVEMP and cVEMP). During the study period 147 consecutive patients with dizziness were examined and 28 (19%) were diagnosed with PPPD, 68% of them were women and the mean age was 59.5 ± 15 years. The median duration of symptoms was 23 months. The most common initial event was vestibular neuritis in 39.3% of patients, followed by benign paroxysmal positional vertigo in 10.7% of patients. Caloric testing was performed in 25 patients. It revealed six cases of unilateral canal paresis. vHIT was performed in 24 patients. There were 13 pathological responses with three cases of lateral canal dysfunction, two cases of posterior, one case of anterior and seven cases of multiple canals affection. VEMP was performed in 23 patients. There were five isolated oVEMP pathologies, one isolated cVEMP pathology and 11 findings of a combined oVEMP and cVEMP pathology. This study provides clinical and neurophysiological data on PPPD and indicates the utility of complete neurophysiological assessment of vestibular function in this group of patients.

Abstract
Alemtuzumab is one of immunomodulatory drugs used for treatment of multiple sclerosis (MS). Although it is very effective it carries significant risk for various side effects. This paper reports a case of young patient who developed pulmonary embolism during the third cycle of alemtuzumab. It is suggested that awareness about possible vascular toxicity of this drug should be raised.

Abstract
BACKGROUND AND PURPOSE As a high proportion of people with clinically isolated syndrome (pwCIS) exhibit sympathetic adrenergic and sudomotor dysfunction, the aim of this study was to investigate the evolution of autonomic nervous system (ANS) abnormalities in pwCIS over a 2-year follow-up. METHODS This was a prospective cohort study in which 121 pwCIS were enrolled and followed for 2 years. After 2-year follow-up, data were available for 84 pwCIS. ANS symptoms were evaluated with the Composite Autonomic System Score-31 (COMPASS-31) and results of the ANS tests were expressed using the Composite Autonomic Scoring Scale (CASS) at baseline and visit at month 24. Symptomatic dysautonomia was defined if the patient had a COMPASS-31 value above the median of the whole cohort at baseline evaluation (COMPASS-31 > 6.79) and CASS score >0. RESULTS Complete CASS data at baseline and month 24 were available for 62 patients; in 24 (38.7%) patients there was worsening, in 16 (25.8%) there was improvement and in 22 (35.5%) there was no change in CASS score. In 90% of pwCIS (72 of 80) there was no change in parasympathetic nervous system tests, whereas 47.3% (35 of 74) had either worsening or improvement in sympathetic adrenergic and 28.6% (20 of 70) had either worsening or improvement in sudomotor function. A multivariable regression model identified the total number of T2 lesions as an independent predictor for worsening of symptomatic dysautonomia. No predictors for worsening or improving of CASS score were identified. CONCLUSION A substantial proportion of pwCIS experienced worsening of ANS abnormalities during the 2-year follow-up and magnetic resonance imaging parameters seemed to predict these abnormalities.

Abstract
BACKGROUND AND PURPOSE The aim of this study was to determine the effect of food intake on the heart rate (HR) in postural orthostatic tachycardia syndrome (POTS). METHODS The following five-phase protocol was applied to 41 subjects who had a sustained HR increment of ≥30 beats/min within 10 min of standing in an initial tilt-table test: 1) 10-min supine phase, 2) 10-min 70°-tilted phase, 3) ingestion of 400 mL of Nutridrink Multi Fibre®, 4) 45-min supine phase, and 5) 10-min 70°-tilted phase. Subjects were divided into four groups: A) difference in HR for standing vs. supine (ΔHR) before the meal of ≥30 beats/min (n=13), B) ΔHR <30 beats/min before the meal but ≥30 beats/min after the meal (n=12), and C) ΔHR <30 beats/min both before and after the meal (n=16). Group D consisted of 10 healthy subjects. RESULTS Before the meal, ΔHR was significantly higher in group A than in all of the other groups, and in group B than in group D (p<0.001). After the meal, ΔHR was significantly higher in groups A and B (p<0.001 and p<0.0001, respectively). When we pooled patients (according to their symptoms) from group A and B into a POTS group and from group C and D into a non-POTS group, an increase in HR of 25 beats/min before the meal had a sensitivity of 92.0% and a specificity of 80.8%. After the meal, an increase in HR of 30 beats/min had a sensitivity of 96.0% and a specificity of 96.2%. CONCLUSIONS Food intake can significantly alter the results of the tilt-table test and so should be taken into account when diagnosing POTS.

Abstract
OBJECTIVES To investigate a possible association between autonomic dysfunction and fatigue in people with multiple sclerosis. METHODS In 70 people with multiple sclerosis early in the disease course (51 females, mean age 33.8 ± 9.1), quantitative sudomotor axon reflex tests, cardiovascular reflex tests (heart rate and blood pressure responses to the Valsalva maneuver and heart rate response to deep breathing), and the tilt table test were performed. Participants completed the Composite Autonomic Symptom Score 31, the Modified Fatigue Impact Scale, and the Epworth Sleepiness Scale, as well as the Beck Depression Inventory. Cutoff scores of ≥ 38 or ≥ 45 on the Modified Fatigue Impact Scale were used to stratify patients into a fatigued subgroup (N = 17 or N = 9, respectively). RESULTS We found clear associations between fatigue and scores in subjective tests of the autonomic nervous system: fatigued patients scored significantly worse on Composite Autonomic Symptom Score 31, and there was a strong correlation between the Modified Fatigue Impact Scale and the Composite Autonomic Symptom Score 31 (rs = 0.607, p < 0.001). On the other hand, we found only modest associations between fatigue and scores in objective tests of the autonomic nervous system: there was a clear trend for lower sweating outputs at all measured sites, which reached statistical significance for the distal leg and foot. We found weak correlations between the Modified Fatigue Impact Scale and the Valsalva ratio (rs = - 0.306, p = 0.011), as well as between the Modified Fatigue Impact Scale and quantitative sudomotor axon reflex tests of the forearm, proximal, and distal lower leg (rs = - 0.379, p = 0.003; rs = - 0.356, p = 0.005; and rs = - 0.345, p = 0.006, respectively). A multiple regression model showed that the Composite Autonomic Symptom Score 31, Beck Depression Inventory, and Epworth Sleepiness Scale were independent predictors of fatigue (p = 0.005, p = 0.019, and p = 0.010, respectively). CONCLUSION These results suggest that-even early in the course of the disease-people with multiple sclerosis suffer from objective and subjective impairments of the autonomic nervous system. The results also point to an association between autonomic nervous system impairment and multiple sclerosis related fatigue.

Abstract
AIM To compare the sensitivity, specificity and accuracy of the 2010 and 2017 revisions of the McDonald criteria in a Croatian cohort of patients with a clinically isolated syndrome (CIS). METHODS Prospectively collected data from 113 patients were retrospectively analyzed. Sensitivity, specificity and accuracy for both criteria were calculated regarding conversion to clinically definite multiple sclerosis (Poser CDMS) or multiple sclerosis (MS) (defined as fulfilment of clinical or MRI evidence for dissemination in space and the development of a second relapse and/or ≥1 new T2 lesions on the follow-up MRIs) during a two-year follow-up. Survival analysis was performed to estimate the cumulative risk of patients developing Poser CDMS. Binary logistic regression model was used to determine which variables are statistically significant predictors for the conversion to MS. RESULTS The 2017 revision had higher sensitivity (85 vs. 30% and 85 vs. 41%) and lower specificity (33 vs. 63% and 63 vs. 85%) compared to the 2010 revisions, for conversion to Poser CDMS and MS, respectively. Patients who did not meet the 2017 McDonald criteria had a higher chance of conversion-free survival for Poser CDMS than those who met the 2017 McDonald criteria (p = 0.037). Results of the multivariate regression analysis revealed that patients who at baseline fulfilled 2017 revisions of the McDonald criteria have the increased likelihood of conversion to MS (Exp(B) 9.68, 95%CI 3.62-25.90, p < 0.00001). CONCLUSION This study provides new information about the application of the 2017 revisions of the McDonald criteria in a Croatian cohort of patients with typical CIS.

Abstract
AIM The aim of this study was to investigate the association of autonomic nervous system abnormalities on head-up tilt table test (HUTT) with generalized joint hypermobility, expressed by Beighton score (BS). METHODS This was a prospective study that included 115 consecutive patients (91 females; mean age 34.35 ± 14.11) referred either for the HUTT or testing of the cardiovascular autonomic reflexes together with HUTT. Generalized joint hypermobility was evaluated according to the BS system after which HUTT was performed. Clinically significant BS was considered if ≥4. RESULTS Fifteen patients (15.1%) had BS ≥4. Results of the HUTT were normal in 58 (50.4%) patients and in 57 (49.6%) patient HUTT was abnormal. Fifteen (13.0%) patients fulfilled criteria for orthostatic hypotension, 30 (26.1%) for reflex syncope and 21 (18.3%) for postural orthostatic tachycardia syndrome. Patients with pathological findings on HUTT had significantly higher BS compared to patients with normal HUTT (median 1 vs. 0, p = 0.001). There was a significant association between participants with BS ≥4 and pathological HUTT (χ[1] = 6.392, p = 0.011). Results of the multivariate regression analysis revealed that increase in the BS is associated with the increased likelihood of HUTT pathology (Exp[B] 1.44, 95% CI 1.084-1.922, p = 0.012), while increase in age is associated with lower risk of HUTT pathology (Exp[B] 0.968, 95% CI 0.939-0.998, p = 0.036). CONCLUSION There is an association between autonomic nervous system abnormalities on HUTT test and generalized joint hypermobility.

Abstract
OBJECTIVE To determine autonomic dysfunction (AD) differences in patients with relapsing remitting multiple sclerosis (pwRRMS) and progressive MS (pwPMS). METHODS Composite autonomic scoring scale (CASS) and heart rate variability (HRV) were performed in 40 pwRRMS and 30 pwPMS. RESULTS pwPMS had a significantly higher sudomotor index and total CASS score compared to pwRRMS (p < 0.001 and p < 0.001, respectively). Disease duration positively correlated with sudomotor index and total CASS (rs = 0.409, p < 0.001 and rs = 0.472, p < 0.001, respectively), while the Expanded Disability Status Scale (EDSS) positively correlated with sudomotor index and total CASS (rs = 0.411, p < 0.001 and rs = 0.402, p = 0.001, respectively) in all patients. Type of multiple sclerosis (pwRRMS or pwPMS) corrected for age, sex and disease duration, was a statistically significant predictor of CASS value (B = 1.215, p = 0.019). Compared to pwRRMS, pwPMS had a significantly lower standard deviation of NN intervals (SDNN), low frequency (LF), and high frequency (HF), during both the supine and tilt-up phases (all p-values <0.006). pwPMS had a significantly lower LF/HF (p = 0.008) during tilt-up. CONCLUSION There is a significant difference in autonomic function in pwRRMS and pwPMS; with pwPMS having a higher burden of AD, which is particularly evident for sweating dysfunction. SIGNIFICANCE Further research is needed to establish whether parasympathetic and sudomotor dysfunction may serve as markers of progressive MS.

Abstract
AIM To validate and cross-culturally adapt Croatian and Serbian versions of composite autonomic symptom score-31 (COMPASS-31) for the detection of dysautonomia in patients with multiple sclerosis (MS). METHODS A total of 179 patients, 67 with clinically isolated syndrome (CIS) and 112 with MS, completed the COMPASS-31 at two MS centers in Zagreb and Belgrade between April 1 and October 31, 2016. Demographic and clinical data including age, gender, MS phenotypes, and the Expanded Disability Status Scale (EDSS) score were collected. RESULTS The Cronbach's alpha coefficient of COMPASS-31 total score was 0.844 for the Croatian MS sample and 0.779 for the Serbian MS sample. A joint analysis yielded Cronbach's alpha coefficients ranging from 0.394 to 0.796, with values in four domains higher than 0.700. In Croatian and Serbian samples and the total study sample, the Cronbach's alpha coefficient of COMPASS-31 was 0.785. Reproducibility measured by intra-class correlation coefficient (ICC) was acceptable (ICC=0.795). With regard to the clinical validity, significant correlation was found between EDSS and the COMPASS-31 total score (P<0.001). Furthermore, significant differences between MS phenotypes were detected for bladder and gastrointestinal domains and for the COMPASS-31 total score (PP<0.001, P=0.005, and P=0.027, respectively). Finally, significant differences between MS phenotypes in patients with score >0, which implies the existence of at least one of the symptoms investigated in each domain, were detected for secretomotor and bladder domains (P=0.015 and PP<0.001, respectively). CONCLUSION COMPASS-31 represents a valid and acceptable self-assessment instrument for the detection of dysautonomia in MS patients.
