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. Methods: 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). Results: 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. Conclusion: 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.
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.
Un an et trois ans après l'apparition des premiers symptômes du SGB, un nombre important de patients donnaient à voir des séquelles neurologiques, ce qui incluait une forme ou une autre d'incapacité fonctionnelle, des symptômes sensoriels, des douleurs et un état de fatigue.
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.
Multiple sclerosis (MS) is a chronic demyelinating neurological disorder predominantly affecting young adults. Based on the data of the MS Atlas 2020, there are 2.8 million people living with MS worldwide. 1 Investigation of the comorbidity burden in persons with MS (PwMS) has become increasingly important since studies have shown that co-occurring conditions may have negative effects on health outcomes in PwMS. 2-4 Among different comorbidity groups, cardiovascular diseases (CVD) are of particular interest because of their high prevalence in the general population, high rank among
