Objectives
Investigation of the comorbidity burden in persons with multiple sclerosis (PwMS) has become increasingly important. The aim of this study was to investigate the relationships of ...cardiovascular disease (CVD) comorbidities and type 2 diabetes with the disability progression.
Materials & Methods
The retrospective cohort study was conducted at the Clinic of Neurology, Belgrade. The Belgrade MS population Registry, which comprises 2725 active MS cases, was used as the source of data. The mean duration of the disease was 21.6 ± 12.5 years. Expanded Disability Status Scale (EDSS) was followed in all PwMS in the Registry. In the statistical analysis, the Cox proportional hazard regression analysis and Kaplan‐Meier curve were performed.
Results
Hypertension statistically significantly contributed to more rapid reaching investigated levels of irreversible disability (EDSS 4.0, 6.0, and 7.0), while the presence of any of the investigated CVD comorbidities and type 2 diabetes significantly contributed to faster reaching EDSS 4.0 and EDSS 6.0. In a multivariable model, progression index (PI) was singled out (HR = 3.171, p < .001), indicating that higher progression index (PI) was an independent predictor of CVD occurrence in MS patients. In the case of type 2 diabetes, PI (p < .001) and MS phenotype (p = .015) were statistically significant in multivariable Cox regression analysis.
Conclusions
Our study confirms the impact of CVD comorbidities and type 2 diabetes in MS on the progression of disability as measured by EDSS in the large cohort of PwMS from the population Registry.
Guillain‐Barré syndrome (GBS) is an acute auto‐immune polyradiculoneuropathy. A huge variety of GBS incidence and mortality rates has been noted across the world. The objective of the present ...multi‐centric study was to assess the incidence and mortality rates of GBS during a 10‐year period in Serbia. We collected data of adult GBS patients who were hospitalized from 2009 to 2018 in all five tertiary healthcare centers in Serbia. The incidence rates per 100 000 inhabitants with 95% confidence intervals (CI) were calculated and further corrected for the estimated number of patients hospitalized in secondary centers. Mortality rates were also assessed. GBS was considered severe if patients were not able to walk at least 10 m without assistance. Six hundred and forty GBS patients were registered in tertiary centers in a 10‐year period. The proportion of severe cases was 75% at nadir, and 52% on discharge. GBS incidence rate in Serbia was 1.1 per 100 000 inhabitants, and estimated incidence if patients from secondary centers included 1.2 per 100 000. Peak incidence was observed during the sixth decade of life. During the acute phase, 5.6% of GBS patients died, while overall 9.7% of them died during 6‐month period from disease onset. This study contributes to our knowledge about GBS epidemiology. Results will allow us to improve the diagnosis and treatment of GBS patients in Serbia.
•SF-36 is able to capture specific life domains omitted by standard outcome measures.•SF-36 score at day 14 is an independent predictor of SF-36 score at month 6.•Neurologists should look both on ...disability and quality of life in GBS patients.
Longitudinal health-related quality of life (QoL) data in Guillain-Barré (GBS) patients are still scarce. We, therefore, investigated health- related QoL in GBS patients from Serbia and surrounding countries during a six-month follow-up period, and analyzed its association with patients' disability. Our study comprised 74 adult patients diagnosed with GBS from May 2017 until May 2018 in seven tertiary healthcare centers. Health-related QoL was investigated using the SF-36 questionnaire, and compared with functional disability assessed by the GBS disability scale (GDS). Tests were performed at day 14, day 28, month 3 and month 6 from disease onset. GDS and SF-36 scores improved over time (p < 0.01). GDS scores were different at all four time points, while SF-36 did not differ between day 14 and day 28. Pooled SF-36 scores (especially physical ones) correlated with pooled GDS scores, except for Bodily Pain and Role Emotional scores. We found that GDS score at day 14 was an independent predictor of GDS score at month 6 (β = +0.52, p < 0.01), while SF-36 score at day 14 was an independent predictor of SF-36 score at month 6 (β = +0.51, p < 0.01). Neurologists should look not only on disability but also on QoL in GBS patients, since these two measures provide us with important complementary items of information.
It is believed that myasthenia gravis (MG) with antibodies to muscle-specific tyrosine kinase (MuSK) is the most severe form of the disease, especially in the first years of the disease. The aim of ...our study was to investigate quality of life (QoL) in a population of patients with MuSK MG compared to those with MG who have antibodies to acetylcholine receptor (AChR) in their sera. The study group consisted of 35 MuSK MG patients (28 females and 7 males), while the control group included 38 AChR MG patients matched for gender, age, and duration of the disease. SF-36 questionnaire was used to evaluate the health-related QoL. Following scales were also used: Hamilton’s scales for depression and anxiety, the Multidimensional Scale of Perceived Social Support, and the Acceptance of Illness Scale. Physical domain scores of QoL were similarly affected in both MuSK and AChR groups, while mental domain and total SF-36 scores were even better in MuSK MG patients. Social support was better in the MuSK group (77.3 ± 9.3 vs. 70.6 ± 14.1,
p
< 0.05). SF-36 total score correlated with depression (rho = 0.54,
p
< 0.01), anxiety (rho = 0.49,
p
< 0.01), and MSPSS (rho = − 0.35,
p
< 0.05), and depression was an independent predictor of worse QoL. Besides therapy of weakness, psychiatric treatment and different forms of psychosocial condition should be part of regular therapeutic protocols for MG. Adequate team work of health professionals and family can provide a healthy mental environment in which a MuSK MG patient would feel more comfortable in spite of the disease.

The aim of the study was to analyze specific features of Guillain‐Barré syndrome (GBS) in old people. The study included 403 GBS patients (62% young <60 years, 35% young‐old 60–80 years, and 3% ...old‐old >80 years). Diagnosis of GBS was made according to the National Institute of Neurological Disorders and Stroke (NINDS criteria). Severe disability (GBS disability score of >3) at nadir was more common in old compared with young patients (p = 0.0001) as was mortality (9% vs. 2%, respectively). Acute motor and sensory axonal neuropathy and hyponatremia were more common in old compared with young patients (12% vs. 6% and 27% vs. 18%, respectively, p = 0.04). A positive history for malignancy was more than three times more common in old than young patients (11% vs. 3%, respectively, p = 0.01). Disability on nadir was similar in young‐old and old‐old subjects with disability on discharge being more severe in old‐old (p = 0.04) suggesting slower recovery in this subgroup. Bulbar symptoms were more common in old‐old compared with young‐old (50% vs. 19%, respectively, p = 0.01). Comorbidities were present in virtually all old‐old patients compared with 66% of young‐old patients (p = 0.04). In conclusion, Elderly patients, and especially old‐old patients, with GBS have more severe disease with slower recovery than do younger patients.
Therapeutic plasma exchange (PLEX) is effective as a second-line treatment of severe relapses of multiple sclerosis (MS) that failed to respond to standard steroid therapy. Our objective was to ...evaluate the effectiveness of PLEX in the severe MS relapses in a cohort of patients treated at Neurology Clinic, University Clinical Centre of Serbia, Belgrade, from 2007 until 2020.PURPOSETherapeutic plasma exchange (PLEX) is effective as a second-line treatment of severe relapses of multiple sclerosis (MS) that failed to respond to standard steroid therapy. Our objective was to evaluate the effectiveness of PLEX in the severe MS relapses in a cohort of patients treated at Neurology Clinic, University Clinical Centre of Serbia, Belgrade, from 2007 until 2020.This retrospective study comprised 107 MS patients with 127 severe relapses treated with PLEX. Majority of our patients suffered from relapsing remitting MS (83.2%), 12.1% had secondary progressive MS and 4.7% had primary progressive MS. Mean age was 39.2 years (range, 19-79 years), female/male ratio 2.3:1. Pulse corticosteroid treatment was used before PLEX in 99.3% of patients. Median EDSS score at nadire during relapse was 6.0 (range 2.0-10.0). After PLEX, 73.8% relapses showed a marked clinical improvement, 7.1% showed mild improvement and in 19.0% there was no improvement. Median EDSS at discharge was 4.0 (6.0 at nadir of relapse vs. 4.0 at discharge; p<0.0001) and it was sustained at the same level, 6 month after PLEX. Multivariate regression analysis showed that higher EDSS at nadir during relapse (OR=0.63, 95% CI 0.41-0.96, p=0.039) and older age (OR=1.07, 95% CI 1.02- 1.12, p=0.010) were significantly associated with poor treatment response after 6- month follow-up. Adverse events occurred in 17.3 of procedures and they were completely resolved.METHODSThis retrospective study comprised 107 MS patients with 127 severe relapses treated with PLEX.

Cerebellar neurodegenerative disorders (CDs) are a heterogeneous group of disorders. It is known that the cerebellum plays a role not only in motor, but also in cognitive and social cognitive ...functions. The aim of this study was to investigate social cognition in patients with different CDs.
Social cognition was examined in 34 patients, 12 with spinocerebellar ataxia type 1 (SCA1), 6 with spinocerebellar ataxia type 2 (SCA2), and 16 with idiopathic late onset cerebellar ataxia (ILOCA). All patients were clinically evaluated using the Scale for the Rating and Assessment of Ataxia. In addition, 34 age, sex, and education-matched healthy control (HC) subjects were similarly analyzed. Social cognition was studied using two tests: the Faux Pas Recognition Test and the Reading the Mind in the Eyes Test (RMET). An appropriate array of neuropsychological tests was used to assess the global cognitive status as well as the frontal functions and mood.
CD patients achieved significantly worse results on both tests of social cognition compared to the HCs. The SCA1 + 2 group achieved the poorest results on the Faux Pas Recognition Test and exhibited poor performance on all cognitive tests, but was only significantly worse compared to the ILOCA group on the Free and Cued Selective Reminding Test (FCSRT) - recognition. The patients in the SCA1 + 2 and ILOCA groups obtained similar scores on RMET. In the SCA1 + 2 group the findings significantly correlated with clinical parameters of disease severity and duration and executive functions (EFs), and with mood and executive functions in the ILOCA group. In the SCA group EFs appeared as the only significant predictor of RMET achievement. The Boston Naming Test (BTN) was a significant predictor of the CD patients' achievement on RMET, while the BTN, the Trail Making Test Part A and FCSRT - Delayed free recall predicted their performance on the Faux Pas Recognition Test.
Patients with CD have social cognitive impairments as demonstrated by the Faux Pas Test and the RMET test results. The SCA1 and 2 patients exhibited a more pronounced impairment compared with the ILOCA patients. The independent cognitive predictors of social cognition impairment were EFs and language.
•All MS patients under cladribine, had IgG antibodies after COVID-19.•All MS patients under cladribine, vaccinated with mRNA develop seroconversion.•All MS patients under alemtuzumab, develop ...seroconversion after vaccination.•Seroconversion occurs independent of absolute lymphocyte count.
It has been generally accepted that people with MS (PwMS) should be vaccinated against COVID-19. The aim of our investigation was to evaluate the humoral response to natural SARS-CoV-2 infection and to two COVID-19 vaccines (BNT162b2 Pfizer-BioNTech and Beijing/Sinopharm BBIBP-CorV) in our cohort of PwMS under high efficacy disease modifying therapies (DMTs), cladribine and alemtuzumab.
Twenty two PwMS treated at the Clinic of Neurology, in Belgrade, who developed COVID-19 and/or were vaccinated against SARS-CoV-2, during treatment with cladribine and alemtuzumab, were included. Out of 18 patients treated with cladribine, 11 developed COVID-19, and 11 were vaccinated against SARS-CoV-2 (four with mRNA vaccine, 7 with Sinopharm). Four MS patients under alemtuzumab were vaccinated against SARS-CoV-2; three with mRNA, and one with Sinopharm vaccine. SARS-Cov-2 IgG response was measured using ELISA anti-spike protein-based serology (INEP, Belgrade, Serbia).
All 7 patients under cladribine treatment who suffered from COVID-19, developed IgG antibodies, 2.0-5.5 months after last symptoms. All four (100%) patients under cladribine who were vaccinated with Pfizer-BioNTech vaccine, and three out of seven (42.9%) vaccinated with Sinopharm, developed antibodies. All 4 patients under alemtuzumab developed antibodies after vaccination. In all cases, seroprotection occurred, irrespective of timing of vaccination and absolute lymphocyte count.
Our findings in a small number of highly active PwMS in whom, lymphodepleting, immune reconstitution therapies, were applied in order to successfully manage MS, indicate that in a number of these patients it was possible to develop at the same time seroprotection in these patients after COVID-19 vaccination in these complex circumstances.
