Background: The treatment of multiple sclerosis, an autoimmune disease that predominantly affects women of reproductive age, has undergone considerable advancements. Nevertheless, their unique needs, particularly those related to motherhood, continue to be disregarded. This study aims to ascertain the needs of women diagnosed with MS about motherhood., Methods: Using the Noblit and Hare methods, meta-synthesis research was conducted on 10 qualitative studies. The relevant studies were obtained by conducting a comprehensive search using keywords in the PubMed, Scopus, Web of Science (ISI), and ProQuest databases without any time limitations until June 2023. The CASP checklist was used to assess the quality of the articles, while the technique of Brown and Clark (2006) was utilized for data synthesis., Results: Four key themes emerged from this meta-synthesis, highlighting the significance of a support system, psychoeducational counseling, knowledge promotion, and continuous, comprehensive, and unique care., Conclusion: Identifying the needs of women diagnosed with MS and addressing these needs concerning motherhood can enhance the quality of services rendered and enhance women's contentment with their choice to embark on motherhood. Furthermore, recognizing these needs during subsequent stages can be utilized in formulating tailored programs catering to this specific cohort of women., (© 2024. The Author(s).)

Background: The maternal role is one of the most challenging yet rewarding roles that women experience in their lives. It begins when a woman becomes pregnant, and as the pregnancy progresses, she prepares to fulfill her role as a mother. A woman's health plays a crucial role in her ability to fulfill the maternal role. Multiple sclerosis (MS), as an autoimmune disease, presents unique challenges in achieving this role. Failing to fulfill the maternal role can have lasting consequences for both the mother and the baby. Given the increasing number of women with MS of reproductive age in Iran and the absence of specific programs for this group during pregnancy and postpartum, researchers have decided to develop a supportive program by exploring the meaning of the maternal role and identifying the needs of these women during this period., Methods/materials: This study will be conducted in 3 stages. The first stage involves a qualitative study to explore the meaning of the "maternal role" in women with MS through a descriptive and interpretive phenomenological approach based on Van Manen's method. Data will be collected through semi-structured interviews with pregnant women with MS and mothers with MS who have children under one-year-old, recruited from the Multiple Sclerosis Society of Mashhad, Iran. The second stage will involve designing a support program based on the findings of the phenomenological study, literature review, and exploratory interviews. A logical model will guide the development of the program, and validation will be conducted using the nominal group technique., Discussion: This study is the first of its kind in Iran to explore the meaning of the maternal role and develop a support program for women with MS. It is hoped that the results of this study will help address the challenges of motherhood faced by these women., (© 2024. The Author(s).)

Objective: The time to diagnosis of multiple sclerosis (MS) is of great importance for early treatment, thereby reducing the disability and burden of the disease. The purpose of this study was to determine the time from the onset of clinical symptoms to the diagnosis of MS and to evaluate the factors associated with a late diagnosis in Iranian MS patients., Methods: The present cross-sectional study was conducted on patients with MS who were registered in the National MS Registry System of Iran (NMSRI)., Results: Overall, 23291 MS patients registered in 18 provinces of Iran were included in this study. The mean (standard deviation) interval between the onset of the disease and diagnosis of MS was 13.42 (32.40) months, and the median was one month. The diagnostic interval of 41.6% of patients was less than one month, and 14.8% of them had a one-month time to diagnosis. Patients with an age of onset below 18 years and those diagnosed after the age of 50 years had a longer time to diagnosis (P<0.001). Patients with primary progressive MS (PPMS) had the longest time to diagnose and those with relapsing-remitting MS (RRMS) had the shortest time (P<0.001). The results of negative binominal regression showed that the average rate of delay in diagnosis in women was 12% less than that in men. The average delay in diagnosis in patients with a positive family history of MS was 23% more than that in others. The rate of delay in the diagnosis of patients with PPMS and secondary progressive MS was 2.22 and 1.66 times higher, respectively, compared with RRMS., Conclusion: The findings of the present study revealed that more than half of the MS patients were diagnosed within a one-month interval from the symptom onset, which is an acceptable period. More attention should be paid to patients' access to medical facilities and MS specialists., (Copyright © 2024. Published by Elsevier B.V.)

Background: Ocrelizumab is a humanized antiCD20, thought to be a highly effective disease-modifying therapy (DMT). Its most frequent adverse effects are infusion-related reactions (IRRs). To reduce these reactions, the first dose of ocrelizumab is administered as two 300 mg infusions separated by two weeks. However, in the phase II trial of ocrelizumab, severe IRRs were not significantly different between two doses of 600 mg dose (two separate 300 mg doses) and 2000 mg dose (two separate 1000 mg doses). We compared the IRRs in undivided full (one 600 mg) and divided (two 300 mg) doses of ocrelizumab which is the standard protocol., Methods: MS patients (relapsing or primary progressive MS) who are selected to receive ocrelizumab by neurologist or MS fellowship were enrolled in an open-label randomized controlled trial. Iranian biosimilar of the drug (Xacrel ® by Cinnagen, approved by the Iranian Food and Drug Administration in 2021) was used. The participants received the first dose of ocrelizumab as either one 600 mg dose in one session or two 300 mg doses in two weeks apart. IRRs during or in the first 24 h after infusion were recorded., Results: Of 332 participants, 150 received two 300 mg doses, and 182 received one 600 mg dose (by random selection). Life-threatening adverse effects were not observed in both groups. Overnight admission or permanent drug discontinuation was not needed. Temporary drug discontinuation was significantly higher in the one 600 mg dose group (p-value < 0.001). During the infusions, malaise (p-value: 0.003), skin reactions (p-value: 0.04), throat swelling (p-value: 0.03), and dyspnea (p-value: 0.01) were significantly increased in the intervention group. However, in the first 24 h, there was no significant difference between two different treatment protocols (one 600 mg dose or two 300 mg doses) in the onset of IRRS (p-value: 0.12)., Conclusion: These findings suggest one 600 mg dose of ocrelizumab administration for the first dose is relatively safe. With some protocol modifications, it could lead to fewer patient referrals, saving time and cost and improvement the access for patients., (© 2023.

Introduction: It is generally recommended to avoid live attenuated vaccines in patients treated with high efficacy disease-modifying treatment (DMT). However, a delay in starting DMT in highly active or aggressive multiple sclerosis (MS) might lead to a significant disability., Objective: We aimed to report a case series of 16 highly active RRMS patients who received the live-attenuated varicella-zoster virus (VZV) vaccine during treatment with natalizumab., Methods: This retrospective case series was conducted between September 2015 and February 2022 at the MS Research Center of Sina and Qaem hospital, Tehran, Mashhad, Iran, to identify the outcome of highly active MS patients who received the live-attenuated VZV vaccine on natalizumab., Results: Two males and 14 females were included in this study, with a mean age of 25.5 ± 8.4-year-old. 10 patients were naïve cases of highly active MS, and six were escalated to natalizumab. The patients received two doses of live attenuated VZV vaccine after a mean of 6.72 cycles of natalizumab treatment. Except for the one who experienced mild chickenpox infection, no serious adverse event or disease activity was evident after vaccination., Conclusion: While our data do not confirm the safety of the live attenuated VZV vaccine in natalizumab recipients, it highlights the importance of case-by-case decision-making in MS management based on the risk-benefit assessment., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflict of interest, and no funding has been used for the manuscript., (Copyright © 2023.

Background: Today, it is estimated that around 5% of multiple sclerosis (MS) patients are in the late-onset category (age at disease onset ≥ 50). Diagnosis and treatment in this group could be challenging. Here, we report the latest update on the characteristics of Iranian patients with late-onset MS (LOMS)., Methods: This cross-sectional study used the information provided by the nationwide MS registry of Iran (NMSRI). The registrars from 14 provinces entered data of patients with a confirmed diagnosis of MS by neurologists. Patients with disease onset at or later than 50 years of age were considered LOMS., Results: Of 20,036 records, the late-onset category included 321 patients (1.6%). The age-standardized LOMS prevalence was around 75 per 100,000 people. 215 patients (67%) were female. Median Expanded Disability Status Scale (EDSS) was 3 (interquartile range: 1.5-5). The majority of the cases (56%) suffered from relapsing-remitting (RR) course while 20% were diagnosed with primary progressive (PP) MS. Significantly higher proportion of male sex, PPMS, and higher EDSS were seen in the late-onset group compared with early-onset and adult-onset cases (p-value < 0.05). Seventy-five (23%) patients did not receive any disease-modifying treatment., Discussion: The more prominent degenerative pathology of LOMS may be the underlying mechanism of the observed differences in comparison to non-LOMS., Conclusion: There are substantial differences and knowledge gaps regarding LOMS which could be the subject of further research., Competing Interests: Declarations of Competing Interests None., (Copyright © 2022 Elsevier B.V.

Background: Therapeutic plasma exchange (TPE) is a conventional second-line treatment for patients with multiple sclerosis (MS) or clinically isolated syndrome with steroid-refractory relapses., Methods: MS and clinically isolated syndrome patients with a steroid-refractory relapse, who fulfilled the indications for TPE were enrolled in this study. An expert nurse recorded the data comprising age, sex, type of MS, disease modifying therapy, disease duration, relapse rate, vital signs at the beginning, during and at the end of each plasma exchange session, plasma exchange volume, normal saline volume, and TPE complications. Ultimately, the statistical association was estimated amongst the variables., Results: A total of 122 cases were assessed. Twelve cases (9.8%) received plasmapheresis for the second time. The mean age was 32.2±8.7 years and 107 (87.7%) were female. In total, 609 plasma exchange sessions were completed. Hypotension and skin reaction were the most clinical complications. Hemoglobin loss and hypokalemia were the most laboratory complications. Fifty-four cases (44.3%) had no complications, 40 (32.8%) had 1 complication, 21 (17.2%) 2 complications, 6 (4.9%) had 3 complications, and 1 (0.8%) disclosed 4 complications. The relapse rate in the past 12 months and the mean plasma volume exchange were significantly different between the groups., Conclusions: We revealed that TPE could be considered as a safe second-line therapy in MS relapses. Hypotension, skin reaction, hemoglobin loss, and hypokalemia were the most complications of TPE in our patients., Competing Interests: The authors declare no conflict of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

The XCL1-XCR1 axis has a potential role in the recruitment of immune cells to the site of inflammation. The present study aimed to examine the relation of XCL1 serum levels with Multiple sclerosis (MS) and HTLV-1-associated myelopathy (HAM), as chronic inflammatory diseases of the central nervous system (CNS). DNA was extracted to evaluate HTLV-1 proviral load (PVL) using real-time PCR. Serum levels of XCL1 was determined by using an ELISA assay. The serum level of XCL1 was significantly higher in patients with HAM than that of asymptomatic carriers (ACs) and healthy controls (HCs) (p < 0.001 and p < 0.0001, respectively) and was also higher in MS patients compared to HCs (p < 0.0001). Moreover, the concentration of XCL1 serum level was significantly different between the ACs and HCs group (p < 0.0001). In conclusion, increased expression of XCL1 might contribute to the migration of autoreactive T cells to the central nervous system and play a critical role in the development and pathogenesis of inflammatory neurological diseases including HAM and MS., Competing Interests: Declaration of competing interest The authors have no competing interests to declare., (Copyright © 2022 Elsevier Ltd.
