RESUMO

Background: Recent research shows that most of the patients with multiple sclerosis (MS) have cognitive-like disorders. Due to the beneficial effects of atomoxetine on improving cognition in limited animal and human surveys, the aim of the present study was to investigate the effect of the atomoxetine on improving cognitive disorders of MS. Methods: This study was a parallel, randomized clinical trial, designed to investigate the effect of atomoxetine drug on the improvement of cognitive impairment (CI) in MS, from April 2021 to March 2022. According to the inclusion and exclusion criteria, a total of 52 participants were involved in the study and then randomly divided in two groups of 26. Experimental group was treated with atomoxetine and the control group was treated with placebo. The Minimal Assessment of Cognitive Function in Multiple Sclerosis (MACFIMS) test was performed for assessment at the beginning and after 3 months. The California Verbal Learning Test (CVLT), the CVLT-delay, the Brief Visuospatial Memory Test-Revised (BVMT-R), and the Symbol Digit Modalities Test (SDMT) were used to evaluate the CI and changes following medication. Finally, data were analyzed by SPSS software at significance level of 0.05. Results: The mean age of patients in the experimental group was 37.7 ± 8.5 and in the placebo group was 37.8 ± 7.6 (P = 0.32). The results showed significant changes in cognitive levels before and after the use of atomoxetine and also in comparison to the placebo group (P < 0.05). Conclusion: This study showed that atomoxetine improved the cognitive domains after administration compared to placebo.

RESUMO

Purpose: Amyotrophic lateral sclerosis (ALS) is an uncommon and aggressive neurodegenerative disorder that influences the lower and upper motor neurons. There are low eligible drugs for ALS treatment; in this regard, supplemental and replacement treatments are essential. There are relative studies in the field of mesenchymal stromal cells (MSCs) therapy in ALS, but the different methods, differently used medium, and difference in follow-up periods affect the outcome treatment. Methods: The current survey is a single-center, phase I clinical trial to evaluating the efficacy and safety of autologous bone marrow (BM)-derived MSCs through intrathecal administration in ALS patients. MNCs were isolated from BM specimens and cultured. The clinical outcome was evaluated based Revised Amyotrophic Lateral Sclerosis Functional Rating (ALSFRS-R) Scale. Results: Each patient received 15±3×106 cells through subarachnoid space. No adverse events (AEs) were detected. Just one patient experienced a mild headache after injection. Following injection, no new intradural cerebrospinal pathology transplant-related was observed. None of the patients' pathologic disruptions following transplantation were detected by magnetic resonance imaging (MRI). The additional analyses have shown the average rate of ALSFRS-R score and forced vital capacity (FVC) reduction have decreased during 10 months following MSCs transplantation versus the pretreatment period, from -5.4±2.3 to -2±3.08 ALSFRS-R points/period (P=0.014) and -12.6±5.22% to -4.8±14.72%/period (P<0.001), respectively. Conclusion: These results have shown that autologous MSCs transplantation reduces the disease's progression and has favorable safety. Trial Registration: This study performed as a phase I clinical trial (code IRCT20200828048551N1).

RESUMO

Introduction: Overactive bladder (OAB) is one of the most common complications in patients with multiple sclerosis (MS). Choosing the effective treatment is very important in improving their quality of life (QOL). Therefore, the aim of this study was to compare solifenacin (SS) and posterior tibial nerve stimulation (PTNS) treatment effects in the MS Patients with OAB. Materials and methods: In total, 70 MS patients suffering from OAB enrolled in this clinical trial study. Patients with a score of at least 3 according to the OAB questionnaire were randomly divided into two groups (35 patients in each group). In one group, patients received SS (5 mg daily for 4 weeks and 10 mg/day for another 8 weeks) and in a second group, patients were treated by PTNS (12 weekly session, 30 min). Results: The mean (SD) age of patients participating in this study was 39.82 (9.088) and 42.41 (9.175) years for the SS group and the PTNS group, respectively. Patients in both groups showed statistically significant improvements in urinary incontinence, micturition, and daytime frequency (p < 0.001). Patients in the SS group had a better response for urinary incontinence after 12 weeks compared to the PTNS group. Also, patients in the SS group reported higher satisfaction and less daytime frequency compared to the PTNS group. Conclusion: SS and PTNS were effective for improving the OAB symptoms in patients with MS. However, patients demonstrated a better experience with SS in terms of daytime frequency, urinary incontinence, and treatment satisfaction rate.

RESUMO

INTRODUCTION: Guillain-Barre Syndrome (GBS) is an autoimmune acute inflammatory demyelinating polyneuropathy usually elicited by an upper respiratory tract infection. Several studies reported GBS associated with Coronavirus Disease 2019 (COVID-19) infection. In this study, we described nine GBS patients following the COVID-19 vaccine. METHODS: In this study, nine patients were introduced from six referral centers for neuromuscular disorders in Iran between April 8 and June 20, 2021. Four patients received the Sputnik V, three patients received the Sinopharm, and two cases received the AstraZeneca vaccine. All patients were diagnosed with GBS evidenced by nerve conduction studies and/or cerebrospinal fluid analysis. RESULTS: The median age of the patients was 54.22 years (ranged 26-87 years), and seven patients were male. The patients were treated with Intravenous Immunoglobulin (IVIg) or Plasma Exchange (PLEX). All patients were discharged with some improvements. CONCLUSION: The link between the COVID-19 vaccine and GBS is not well understood. Given the prevalence of GBS over the population, this association may be coincidental; therefore, more studies are needed to investigate a causal relationship.

RESUMO

BACKGROUND: Stroke is the third common cause of mortality and the most common cause of morbidity in adults. MLC601 (NeuroAiD™) is a treatment indicated for post stroke recovery. An increase of impaired cerebral blood flow may be an important parameter for recovery processes. The aim of this study was to investigate the effect of MLC601 on cerebral blood flow velocity as an indirect evidence of cerebral blood flow increase in post stroke subjects. METHODS: This is a double-blinded, placebo controlled, randomized study of 80 subjects included within a week of stroke onset. All subjects were given either MLC601 or placebo, 4 capsules, 3 times a day for 3 months. Cerebral blood flow within the middle cerebral artery, with blood flow velocity measured by transcranial Doppler (TCD), and Barthel index was assessed at baseline and at 3 months. RESULTS: The mean change in cerebral blood flow velocity in the MLC601 treatment group (15.9) was significantly increased (p=0.009) compared to the placebo group (9.6). Subjects in the treatment group also showed a significant difference in the mean rank of modified ranking scale (p<0.001) and mean change of the Barthel Index: 36 vs. 29 in the placebo group (p<0.001). CONCLUSION: This is the first study suggesting that treatment with MLC601 may increase cerebral blood flow in stroke subjects. This may be mediated by an effect on stimulating microcirculation, an important process contributing to neuroplasticity in the central nervous system. This effect on cerebral blood flow may be associated with improvement in measures of functional recovery.
