Abstract
INTRODUCTION Epilepsy is a disorder of recurrent, unprovoked seizures affecting approximately 15 million individuals of childbearing potential worldwide. Patients with epilepsy rely on regular daily therapy with antiseizure medications (ASMs). Furthermore, ASMs are also prescribed for other neuropsychiatric indications (e.g. bipolar disorder, pain, migraines) with over 2% of the pregnancies in the United States involving prenatal exposure to ASMs. AREAS COVERED ASM concentrations are affected by hormonal and physiological changes in pregnancy, including increases in renal and hepatic blood flow, decreased protein binding, and changes in enzyme activity. Clearance changes typically reverse within a few weeks after delivery. During pregnancy, many ASMs, such as lamotrigine, levetiracetam, and oxcarbazepine, should have serum concentrations monitored and doses increased to maintain the individualized target range for seizure control. ASMs metabolized via glucuronidation, primarily lamotrigine, undergo marked increases in clearance throughout pregnancy, requiring about 3-fold the pre-pregnancy daily dose by delivery. Postpartum, ASM doses are usually decreased over several weeks to prevent drug toxicity. EXPERT OPINION In the future, the development of a physiologically-based pharmacokinetic model for various ASMs may enable empiric dose adjustments in pregnancy without the difficulties of frequent therapeutic drug monitoring.

Abstract
BACKGROUND Women have a higher risk of developing multiple sclerosis (MS) than men. The natural reproductive period from menarche to menopause corresponds to the period of active inflammatory disease in MS. Mothers and pregnant women with MS need information about how their disease may affect pregnancy and breastfeeding. AIM The aim was to explore the reproductive factors in an MS-diagnosed population and to identify ways to support patients and their decision-making process. METHODS We conducted a cross-sectional, Web-based survey of women living with MS in Asturias (Spain) using a community-based participatory approach. FINDINGS Early menarche may predict the onset of MS. Pregnancy improves the general health of patients and reduces the number of relapses. Breastfeeding is often not practised and may cause concern in women. MS does not affect the age of menopause, but it can worsen symptoms. However, menopause does not increase the number of MS relapses. CONCLUSIONS MS is increasingly diagnosed at an earlier age, which increases the number of women who become pregnant after being diagnosed with MS. The decrease in MS relapses during pregnancy and the increase during the postpartum period are consistent with previous reports. Women who choose to breastfeed are in the minority due to treatment incompatibility, although some currently used treatments are compatible with breastfeeding. However, there is a lack of information on this which should be investigated.

Abstract
Morphological femininity depends mainly on estrogen levels at puberty and is perceived as a cue of a woman's biological condition. Due to the immunostimulant properties of estradiol, estradiol-dependent feminine traits are expected to be positively related to immunity. However, heightened immunity in women may increase the risk of autoimmune disease, thus the relationship between femininity and immune quality may be complex. This study aimed to assess the relationship between morphological femininity and both the occurrence and severity of Hashimoto thyroiditis (HT) in women of reproductive age. Moreover, 95 women with HT and 84 without HT (all between 20 and 37 years) participated in the study. Morphological femininity was assessed based on somatic measurements of sexually dimorphic traits (2D:4D ratio, WHR, breast size, facial sexual dimorphism). The occurrence and severity of HT were assessed by serum TPOAb levels. The results showed that only the 2D:4D ratio of the right hand was higher in the HT group, indicating higher femininity in these women. However, there was also a positive relationship between facial femininity and TPOAb level in women with HT, indicating a higher severity of the disease. The results suggest that prenatal and pubertal exposure to estrogens may increase the probability or severity of autoimmune diseases in adulthood, but the relationship is tentative.

Abstract
Multiple sclerosis (MS) is a common disease in young women of reproductive age, characterized by demyelination of the central nervous system (CNS). Understanding how genes related to MS are expressed during pregnancy can provide insights into the potential mechanisms by which pregnancy affects the course of this disease. This review article presents evidence-based studies on these patients' gene expression patterns. In addition, it constructs interaction networks using bioinformatics tools, such as STRING and KEGG pathways, to understand the molecular role of each of these genes. Bioinformatics research identified 25 genes and 21 signaling pathways, which allows us to understand pregnancy patients' genetic and biological phenomena and formulate new questions about MS during pregnancy.

Abstract
BACKGROUND After natalizumab discontinuation severe relapses can occur despite pregnancy, but third trimester exposure is associated with neonatal haematological abnormalities (HA). The best time point for stopping natalizumab during pregnancy is unclear. METHODS Prospective, observational cohort with 350 natalizumab exposed pregnancies from the German Multiple Sclerosis and Pregnancy Registry. Clinical disease activity and neonatal outcomes are compared between women with natalizumab discontinuation during (1st Trim-group) versus after the first trimester (maintaining-group) and for subgroup analysis before (<30-subgroup) or after (≥30-subgroup) the 30th gestational week (gw). RESULTS Baseline characteristics did not significantly differ between the 1st Trim-group (n=179; median exposure duration: 2.60 gw, IQR 1.30-3.60) and the maintaining-group (n=171; median exposure duration: 30.9 gw, IQR 26.9-33.3). Fewer relapses occurred during pregnancy and the postpartum year in the maintaining-group (25.7%) compared with the 1st Trim-group (62.6%; p<0.001). Women in ≥30-subgroup had a significantly lower relapse risk in the first 6 months postpartum (relapse rate ratio: 0.36, 95% CI: 0.15 to 0.84). In total, 7.5% retained meaningful disability 12 months postpartum. No significant effect on neonatal outcomes were observed, but anaemia (OR: 2.62, 95% CI: 1.12 to 6.52) and thrombocytopaenia (OR: 2.64, 95% CI: 1.15 to 6.46) were significantly more common in the ≥30-subgroup. 21.8% of all neonates were born small for gestational age, independent of the timing of natalizumab discontinuation. CONCLUSION Continuing natalizumab during pregnancy after gw 30 decreases the relapse risk postpartum going along with a higher risk for HA in the newborns. These results add relevant knowledge as a basis for informed risk-benefit discussion.

Abstract
INTRODUCTION Multiple Sclerosis is a disease of young females at a reproductive age. OBJECTIVE discuss family planning in the context of providing care for women with MS. METHOD patients with Multiple Sclerosis, female, aged between 18 and 45 years, from 01/Nov/2021 to 16/Jan/2022 participated, all of whom answered a questionnaire made available on the Google forms platform. RESULTS A total of 233 responses were validated. Most patients discuss family planning during their medical care (61.4 %), use low-efficacy contraceptive methods (68.7 %) and do not plan to become pregnant (70.1 %). There is a high rate of use of disease-modifying treatments (88.9 %). Among those who had already become pregnant, most of them became pregnant before diagnosis and were statically younger than patients who became pregnant after diagnosis. CONCLUSION Family planning should be discussed early on and be actively initiated by the health care professional assisting the patient and incorporated into the routine consultation. We suggest efforts should be put into ensuring a decrease in the rate of unplanned pregnancy in this population. Also, it is crucial to guarantee effective contraception in patients who express the wish not to become pregnant and are using disease-modifying treatments.

Abstract
BACKGROUND Multiple sclerosis (MS) predominantly affects women of childbearing age. Due to the risk of teratogenicity, women with active multiple sclerosis (MS) who require high-efficacy therapies (HET) may need to discontinue treatment during pregnancy. Fingolimod and Natalizumab withdrawal increases the risk of disease reactivation, a risk not commonly associated with anti-CD20 therapies. However, comparative data are limited during pregnancy and post-partum. Our aim was to compare evidence of disease activity during pregnancy and post-partum in women treated with HET (anti-CD20 therapies, Natalizumab or Fingolimod) before conception, whether or not exposed during pregnancy. METHODS In this single-center retrospective study, we included consecutive pregnancies of relapsing-remitting MS patients and classified them in three groups according to the last HET used before conception: « anti-CD20 » « Natalizumab (NTZ) » and « Fingolimod (FGD) ». The main outcome was annualized relapse rate (ARR) during pregnancy and post-partum. RESULTS We included 66 pregnancies: 21, 24 and 21 in anti-CD20, NTZ and FGD groups respectively. Overall, mean ARR (SD) increased from 0.36 (0.6) during the preconception year to 0.60 (1.3) during pregnancy and to 1.03 (2.0) in the first 3 months post-partum. Mean ARR in anti-CD20 group (0.09 (0.3)) during pregnancy and the first 3 months post-partum was lower compared with NTZ (0.48 (0.6); p = 0,09) and FGD (1.50 (1.8); p = 0.001) groups. Proportion of pregnancies with radiological activity during pregnancy and post-partum in anti-CD20 group (5.2 %) was lower compared with NTZ (63.1 %; p < 0.001) and FGD (72.2 %; p < 0.001) groups. There was no significant difference in the evolution of EDSS score from conception to post-partum between each group (p = 0.75). CONCLUSION Evidence of disease activity was significantly lower in patients exposed to anti-CD20 therapies before conception. This study suggests that use of anti-CD20 therapies is an efficient option to prevent disease reactivation during pregnancy and post-partum.

Abstract
Multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) are two of the most devastating immune-mediated central demyelinating disorders. NMOSD was once considered as a variant of MS until the discovery of an antibody specific to the condition. Despite both MS and NMOSD being considered central demyelinating disorders, their pathogenesis and clinical manifestations are distinct, however the exact mechanisms associated with each disease remain unclear. Extracellular vesicles (EVs) are nano-sized vesicles originating in various cells which serve as intercellular communicators. There is a large body of evidence to show the possible roles of EVs in the pathogenesis of several diseases, including the immune-mediated central demyelinating disorders. Various types of EVs are found across disease stages and could potentially be used as a surrogate marker, as well as acting by carrying a cargo of biochemical molecules. The possibility for EVs to be used as a next-generation targeted treatment for the immune-mediated central demyelinating disorders has been investigated. The aim of this review was to comprehensively identify, compile and discuss key findings from in vitro, in vivo and clinical studies. A summary of all findings shows that: 1) the EV profiles of MS and NMOSD differ from those of healthy individuals, 2) the use of EV markers as liquid biopsy diagnostic tools appears to be promising biomarkers for both MS and NMOSD, and 3) EVs are being studied as a potential targeted therapy for MS and NMOSD. Any controversial findings are also discussed in this review.

Abstract
Background Patient disability, relapse rate, and age are used for family planning in multiple sclerosis (MS). However, the need for more accurate biomarkers is widely recognized. We aimed to explore the influence of age on neurofilament light chain (sNfL), which reflects acute inflammation; glial fibrillary acidic protein (GFAP), associated with disability progression independent of relapses; and anti-Müllerian hormone (AMH), reflecting ovarian reserve, to provide a tailored family planning strategy. Methods This case-control study included 95 MS patients and 61 healthy control women (HCW). sNfL and GFAP levels were measured using a sensitive single-molecule array assay. AMH levels were measured by the automated Elecsys® Anti-Müllerian Hormone Assay. Results We observed no significant differences in AMH values between MS patients and the control group within any of the age-matched categories. Age exhibited a negative correlation with AMH values in both groups, as expected. Nevertheless, our findings suggest a slight tendency toward reduced ovarian reserve in MS patients (rho MS patients = -0.67, p < 0.0001; rho HCW = -0.43, p = 0.0006). Interestingly, among the 76 MS participants under 40 years old, we identified ten individuals (13.1%) with AMH levels below 0.7 ng/ml, indicative of a low ovarian reserve, and an additional six individuals (7.8%) with AMH levels between 0.7 ng/ml and 0.9 ng/ml, suggesting a potential risk of premature ovarian failure. Conversely, sNfL and GFAP levels in the MS group exhibited high variability but showed no significant association with age intervals. Conclusion We found no significant differences in AMH, sNfL or GFAP values between MS patients and the control group within any of the age-matched categories. The assessment of AMH, sNFL and GFAP levels at MS onset facilitates personalized therapeutic and family planning strategies for childbearing-age women.

Abstract
BACKGROUND The modulation of the activity disease in patients with Multiple Sclerosis (MS) that occurs during pregnancy is a helpful model which could provide insight into central disease mechanisms and facilitate treatment. Therefore, the aim of the study was to identify differentially expressed genes in-silico to perform biological function pathway enrichment analysis and protein-protein interaction from pregnant women with MS. METHODS Transcriptome data were obtained from the Gene Expression Omnibus (GEO) database. We selected the microarray dataset GSE17449. The gene expression dataset contains the data of mononuclear cells from four different groups sought, including seven healthy women (H), four healthy pregnant women (HP), eight women with multiple sclerosis (WMS), and nine women nine months pregnant with multiple sclerosis (PMS). The GSEA software was employed for enrichment analysis, and the REACTOME database was used for biological pathways. The protein-protein interaction (PPI) network was plotted with STRING. The databases used to identify the connection of DEGs with different signaling pathways were KEGG and WIKIPATHWAYS. RESULTS We identified 42 differentially expressed genes in pregnant women with MS. The significant pathways included IL-10 signaling pathway, ErbB2 activates, the hemoglobin complex (HBD, HBB, HBA1, AHSP, and HBA2), IL-17 signaling pathway (LCN2 and MMP9), antigen processing and presentation, and Th17 cell differentiation (HLA-DQA1), Rap1 signaling pathway (ID1), NOD-Like receptor signaling pathway (CAMP and DEFA4), PD-L1 Signaling, Interferon gamma signaling (MMP9 and ARG1), Neutrophil degranulation (CAMP, DEFA4, ELANE, CEACAM8, S100P, CHI3L1, AZU1, OLFM4, CRISP3, LTF, ARG1, PGLYRP1, and TCN1). In the WIKIPATHWAYS set, significance was found Vitamin B12 metabolism (TCN1, HBB, and HBA2), and IL-18 signaling pathway (S100P). CONCLUSION This study can be used to understand several essential target genes and pathways identified in the present study, which may serve as feasible targets for MS therapies.

Klehmet J, Begus-Nahrmann Y, Taipale K, Niemczyk G, Rehberg-Weber K. Pregnancy outcomes in female multiple sclerosis patients exposed to intramuscular interferon beta-1a or peginterferon beta-1a reported in a German Patient Support Programme - results from the non-interventional post-authorization safety study PRIMA. Ther Adv Neurol Disord 2023; 16:17562864231214041. [PMID: 38107443 PMCID: PMC10725088 DOI: 10.1177/17562864231214041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Accepted: 10/27/2023] [Indexed: 12/19/2023] Open
Abstract
Background Based on data from two large cohort studies, a label update became applicable for the class of interferon beta therapies in 9/2019, allowing interferons during pregnancy and breastfeeding. Objective To assess pregnancy outcomes of women with multiple sclerosis (MS) exposed to peginterferon beta-1a or intramuscular interferon beta-1a therapy (IFN). Design Non-interventional post-authorization safety study. Methods PRIMA was conducted from April to October 2021 in Germany. Retrospective pregnancy data were retrieved from adult female patients diagnosed with relapsing-remitting MS or clinically isolated syndrome, exposed to IFN before or during pregnancy and registered in the patient support programme (PSP) of the marketing authorization holder's MS Service Centre. The primary endpoint was the outcome of pregnancy. Prospective postpartum data were collected from mothers reporting live births. Results In total, 426 women reporting 542 pregnancies between December 2001 and July 2020 (14 pregnancies after the label update) were enrolled. Among patients with confirmed exposure during pregnancy (N = 362), 306 pregnancies (84.5%) resulted in live births (77.6% without defects, 1.9% with defects and 4.4% preterm). Spontaneous abortion, elective termination and stillbirth were reported in 10.9%, 2.8% and 0.2% of the cases, respectively. Higher rates of spontaneous abortions were reported in women with continuous IFN use. A total of 162 women completed the questionnaire for 192 live births within the prospective study part. Mothers restarted IFN therapy or switched to another disease-modifying therapy postpartum in 51.0% and 14.1% of cases, respectively. 158/192 infants (82.3%) were breastfed [34/158 (21.5%)] during IFN therapy. Postpartum relapse activity was low (mothers of 87.3% of breastfed infants remained relapse-free during lactation). Conclusion Overall, the prevalence of spontaneous abortions and congenital anomalies of females exposed to IFN exposure before or during pregnancy was within the range reported for the general population. Most mothers paused IFN during pregnancy and breastfeeding. Relapse activity during pregnancy and lactation was observed to be low. These real-world data from a PSP corroborate European and Scandinavian registry data. Trial registration NCT04655222, EUPAS38347.

Abstract
There is a lack of published guidelines on the management of patients with multiple sclerosis (MS) undergoing procedures that require anaesthesia and respective advice is largely based on retrospective studies or case reports. The aim of this paper is to provide recommendations for anaesthetists and neurologists for the management of patients with MS requiring anaesthesia. This review covers issues related to the anaesthetic management of patients with MS, with a focus on preoperative assessment, choice of anaesthetic techniques and agents, side-effects of drugs used during anaesthesia and their potential impact on the disease evolution, drug interactions that may occur, and the need to use monitoring devices. A systematic PubMed research was performed to retrieve relevant articles.

Abstract
BACKGROUND AND PURPOSE Data on disease-modifying therapy (DMT) exposure throughout pregnancy in patients with multiple sclerosis are scarce. In this analysis, we assessed pregnancy and fetal outcomes following maternal glatiramer acetate (GA) exposure in all three trimesters among cases reported between 1997 and 2020. METHODS Pregnancy reports of maternal in utero exposure to 20 and 40 mg/mL GA in all three trimesters from 1997 to 2020 were eligible. Both prospective pregnancy data, reported prior to knowledge of pregnancy outcome, and retrospective data were included. The primary endpoint was major congenital malformations (MCMs) based on the European Surveillance of Congenital Anomalies and Twins (EUROCAT) classification. Additional endpoints included fetal death, preterm birth, and low birth weight. The MCM rate was compared to the EUROCAT background rate. RESULTS A total of 618 GA-exposed pregnancies in all three trimesters resulted in 634 fetuses, including 14 twin pregnancies. One fetal death was reported. All 414 fetuses with data reported prior to knowledge of pregnancy outcome (prospective data) were live births and no fetal death was reported. Preterm birth was reported in 23/213 (10.8%) pregnancies with known gestational age. Low birth weight was reported in 13/203 (6.4%) infants with known birth weight. The prevalence of MCM in prospective live births ranged from 2.2% to 2.4%, which was similar to background rates (2.1%-3.0%). The frequency of these pregnancy and infant outcomes was comparable across GA doses. CONCLUSIONS In utero exposure to 20 and 40 mg/mL GA in three trimesters of pregnancy does not appear to be related to adverse pregnancy or infant outcomes.

Abstract
Many autoimmune disorders exhibit flares in which symptoms erupt and then decline, as exemplified by multiple sclerosis (MS) in its relapsing-remitting form. Existing mathematical models of autoimmune flares often assume regular oscillations, failing to capture the stochastic and non-periodic nature of flare-ups. We suggest that autoimmune flares are driven by excitable dynamics triggered by stochastic events auch as stress, infection and other factors. Our minimal model, involving autoreactive and regulatory T-cells, demonstrates this concept. Autoimmune response initiates antigen-induced expansion through positive feedback, while regulatory cells counter the autoreactive cells through negative feedback. The model explains the decrease in MS relapses during pregnancy and the subsequent surge postpartum, based on lymphocyte dynamics. Additionally, it identifies potential therapeutic targets, predicting significant reduction in relapse rate from mild adjustments of regulatory T cell activity or production. These findings indicate that excitable dynamics may underlie flare-ups across various autoimmune disorders, potentially informing treatment strategies.

Brain MRI activity during the year before pregnancy can predict long-term clinical worsening in patients with Multiple Sclerosis. Neurol Sci 2023; 44:3989-3996.

Abstract
BACKGROUND Pregnancy has been observed to reduce the frequency of relapses in Multiple Sclerosis (MS) patients, but the relapse risk tends to increase during the early post-partum period. Increased pre- and post-partum disease activity may predict a poor long-term prognosis. This study aimed to evaluate the correlation between magnetic resonance imaging (MRI) activity during the year before pregnancy and long-term clinically meaningful worsening in Expanded Disability Status Scale (EDSS). METHODS This observational, retrospective, case-control study included 141 pregnancies in 99 females with MS. Statistical analyses were used to evaluate the correlation between MRI activity during the year pre-pregnancy and post-partum clinical worsening during a 5-year follow-up. Clustered logistic regression was used to investigate the predictors of 5-year clinically meaningful worsening in EDSS (lt-EDSS). RESULTS We found a significant correlation between an active MRI pre-pregnancy and lt-EDSS (p = 0.0006). EDSS pre-pregnancy and lt-EDSS were also significantly correlated (p = 0.043). Using a multivariate model, we predicted which females would not experience long-term clinical deterioration by a stable MRI pre-pregnancy (92.7% specificity; p = 0.004). CONCLUSIONS An active MRI pre-conception is a strong predictor of lt-EDSS and a higher annual relapse rate during the follow-up period, regardless of whether the female had clinical evidence of disease activity prior to conception and delivery. Optimizing disease control and achieving imaging stability prior to conception may reduce the risk of long-term clinical deterioration.

Abstract
INTRODUCTION Multiple Sclerosis (MS) is a chronic disease affecting around 2.8 million people worldwide. Two-thirds are women, and the mean age at diagnosis is about 30 years old. Social trends are moving towards older age at first pregnancy, both in women with and without MS. OBJECTIVES To determine the frequency of diminished ovarian reserve (DOR) through anti-Mullerian Hormone (AMH) measurement in women with MS at fertile age and Healthy Females (HF) in Chile. METHODS Case-control, multicentric, cross-sectional study including relapsing-remitting people with MS (pwMS) between 18 and 40 years and sex and age-matched HF. We obtained a blood sample to determine AMH levels. We defined DOR as AMH <1.5 ng/mL and very-low AMH levels as <0.5 ng/mL. Also, we performed questions regarding reproductive decision-making. RESULTS We included 79 sex and age-matched HF and 92 pwMS, median age 32(19-40) years, median disease duration 6 (1-17)years, median EDSS 1.0 (0-6), 95% were receiving disease-modifying therapy (DMT), 70% high-efficacy DMT and 37% with a treatment that contraindicates pregnancy. DOR was observed in 24% (n = 22) of the pwMS, compared to 14% (n = 11) of the HF (p = 0.09), while very-low AMH levels were observed in 7.6% (n = 7) of pwMS and none of the HF (p = 0.0166). We observed an inverse correlation between age and AMH levels. Age was the only significant risk factor for low AMH levels in pwMS (OR 1.14 95%CI(1.00-1-31), p = 0.04), including smoking, body mass index (BMI), hormonal contraception, autoimmune comorbidity, high/low-moderate efficacy DMT, and active disease as covariables. We did not find statistically significant differences in age at diagnosis, BMI, disease duration, EDSS, autoimmune comorbidity, use of hormonal contraception, or percentage of active disease between MS women with normal vs DOR. Over 70% of pwMS desired to become pregnant in the future, while 60% considered that the diagnosis of MS was a limitation for pregnancy planning. CONCLUSIONS No differences in DOR, measured by levels of AMH, were observed between pwMS MS and HF in Chile. As expected, AMH levels were correlated only with ageing. This information may be evaluated early during the disease course to help patients and neurologists with fertility counselling and family planning considerations regarding DMT use.

Abstract
OBJECTIVE Postpartum, patients with multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) have increased risk for disease activity. Anti-CD20 IgG1 monoclonal antibodies (mAb) are increasingly used as disease-modifying therapies (DMTs). Patients may wish to both breastfeed and resume DMT postpartum. This study aimed to determine the transfer of anti-CD20 IgG1 mAbs, ocrelizumab, and rituximab (OCR/RTX), into mature breastmilk and describe maternal and infant outcomes. METHODS Fifty-seven cis-women receiving OCR/RTX after 59 pregnancies and their infants were enrolled and followed up to 12M postpartum or 90 days post-infusion. Breastmilk was collected pre-infusion and serially up to 90 days and assayed for mAb concentration. Medical records and patients' questionnaire responses were obtained to assess neurologic, breastfeeding, and infant development outcomes. RESULTS The median average concentration of mAb in breastmilk was low (OCR: 0.08 μg/mL, range 0.05-0.4; RTX: 0.03 μg/mL, range 0.005-0.3). Concentration peaked 1-7 days post-infusion in most (77%) and was nearly undetectable after 90 days. Median average relative infant dose was <1% (OCR: 0.1%, range 0.07-0.7; RTX: 0.04%, range 0.005-0.3). Forty-three participants continued to breastfeed post-infusion. At 8-12 months, the proportion of infants' growth between the 3rd and 97th World Health Organization percentiles did not differ for breastfed (36/40) and non-breastfed (14/16, p > 0.05) infants; neither did the proportion with normal development (breastfed: 37/41, non-breastfed: 11/13; p > 0.05). After postpartum infusion, two mothers experienced a clinical relapse. INTERPRETATION These confirm minimal transfer of mAb into breastmilk. Anti-CD20 mAb therapy stabilizes MS activity before conception to the postpartum period, and postpartum treatments appears to be safe and well-tolerated for both mother and infant.

Abstract
Background Multiple sclerosis (MS) is one of the most common neurological disorders in the world, and it is the leading cause of non-traumatic disability among young adults. While genetic susceptibility plays a role in MS development, the condition is not directly hereditary. Nevertheless, MS tends to aggregate within families, with first-degree relatives of affected individuals facing a higher risk than the general population. Additionally, family planning knowledge is insufficient among MS patients. Hence, this study aimed to assess the influence of MS disease on family planning and define the factors influencing decision-making regarding family planning in multiple sclerosis patients in the Eastern province of Saudi Arabia. Methodology A prospective study was conducted in Eastern Province, Saudi Arabia, during the period of 2022-2023 through directly interviewing the patients using a pre-validated questionnaire. This study would improve counseling and future care plans regarding family planning during patients' visits. Results A total of 57 women with MS were enrolled in this study; 35 (61.4%) patients got pregnant after the onset of the disease, and 46 (97.9%) had healthy children. A total of 23 (40.4%) were previously aborted due to the disease. Only five (8.8%) diseased women experienced relapses of the disease during previous pregnancies. A total of 14 (24.6%) women reported that generally their condition improved during pregnancy and childbirth, and 12 (21.1%) had no change, while four (7%) reported that their condition generally deteriorated. Also, 15 (26.3%) had no change in their condition during the first three months after birth, while four (7%) experienced deteriorated condition. Exactly 71.2% reported that the disease mostly affected their planning for pregnancy, which was of greater extent among 24.6% and partial among 14%. Conclusion Multiple sclerosis affects women's decisions regarding family planning. The most reported causes among affected women included anxiety about weakness and lack of strength during childbirth, concern about possible side effects from MS drugs on the fetus (congenital malformations), worry about not being able to take care of a child due to illness and the severe impact of the disease on their health.

Abstract
BACKGROUND Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system that affects millions of people worldwide. The disease course varies greatly across individuals and many disease-modifying treatments with different safety and efficacy profiles have been developed recently. Prognostic models evaluated and shown to be valid in different settings have the potential to support people with MS and their physicians during the decision-making process for treatment or disease/life management, allow stratified and more precise interpretation of interventional trials, and provide insights into disease mechanisms. Many researchers have turned to prognostic models to help predict clinical outcomes in people with MS; however, to our knowledge, no widely accepted prognostic model for MS is being used in clinical practice yet. OBJECTIVES To identify and summarise multivariable prognostic models, and their validation studies for quantifying the risk of clinical disease progression, worsening, and activity in adults with MS. SEARCH METHODS We searched MEDLINE, Embase, and the Cochrane Database of Systematic Reviews from January 1996 until July 2021. We also screened the reference lists of included studies and relevant reviews, and references citing the included studies. SELECTION CRITERIA We included all statistically developed multivariable prognostic models aiming to predict clinical disease progression, worsening, and activity, as measured by disability, relapse, conversion to definite MS, conversion to progressive MS, or a composite of these in adult individuals with MS. We also included any studies evaluating the performance of (i.e. validating) these models. There were no restrictions based on language, data source, timing of prognostication, or timing of outcome. DATA COLLECTION AND ANALYSIS Pairs of review authors independently screened titles/abstracts and full texts, extracted data using a piloted form based on the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies (CHARMS), assessed risk of bias using the Prediction Model Risk Of Bias Assessment Tool (PROBAST), and assessed reporting deficiencies based on the checklist items in Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or Diagnosis (TRIPOD). The characteristics of the included models and their validations are described narratively. We planned to meta-analyse the discrimination and calibration of models with at least three external validations outside the model development study but no model met this criterion. We summarised between-study heterogeneity narratively but again could not perform the planned meta-regression. MAIN RESULTS We included 57 studies, from which we identified 75 model developments, 15 external validations corresponding to only 12 (16%) of the models, and six author-reported validations. Only two models were externally validated multiple times. None of the identified external validations were performed by researchers independent of those that developed the model. The outcome was related to disease progression in 39 (41%), relapses in 8 (8%), conversion to definite MS in 17 (18%), and conversion to progressive MS in 27 (28%) of the 96 models or validations. The disease and treatment-related characteristics of included participants, and definitions of considered predictors and outcome, were highly heterogeneous amongst the studies. Based on the publication year, we observed an increase in the percent of participants on treatment, diversification of the diagnostic criteria used, an increase in consideration of biomarkers or treatment as predictors, and increased use of machine learning methods over time. Usability and reproducibility All identified models contained at least one predictor requiring the skills of a medical specialist for measurement or assessment. Most of the models (44; 59%) contained predictors that require specialist equipment likely to be absent from primary care or standard hospital settings. Over half (52%) of the developed models were not accompanied by model coefficients, tools, or instructions, which hinders their application, independent validation or reproduction. The data used in model developments were made publicly available or reported to be available on request only in a few studies (two and six, respectively). Risk of bias We rated all but one of the model developments or validations as having high overall risk of bias. The main reason for this was the statistical methods used for the development or evaluation of prognostic models; we rated all but two of the included model developments or validations as having high risk of bias in the analysis domain. None of the model developments that were externally validated or these models' external validations had low risk of bias. There were concerns related to applicability of the models to our research question in over one-third (38%) of the models or their validations. Reporting deficiencies Reporting was poor overall and there was no observable increase in the quality of reporting over time. The items that were unclearly reported or not reported at all for most of the included models or validations were related to sample size justification, blinding of outcome assessors, details of the full model or how to obtain predictions from it, amount of missing data, and treatments received by the participants. Reporting of preferred model performance measures of discrimination and calibration was suboptimal. AUTHORS' CONCLUSIONS The current evidence is not sufficient for recommending the use of any of the published prognostic prediction models for people with MS in clinical routine today due to lack of independent external validations. The MS prognostic research community should adhere to the current reporting and methodological guidelines and conduct many more state-of-the-art external validation studies for the existing or newly developed models.

Impact of interferon beta exposure on birth outcome and child development - Results from the post-authorisation safety study PRIMA. Mult Scler Relat Disord 2023; 77:104844. [PMID: 37393802 DOI: 10.1016/j.msard.2023.104844] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 05/26/2023] [Accepted: 06/19/2023] [Indexed: 07/04/2023]
Abstract
BACKGROUND Interferon beta therapies are well-established disease-modifying treatments for patients with relapsing multiple sclerosis (MS). Based on clinical evidence from two large cohort studies, both, the EMA and FDA updated the labels of the interferon beta class in terms of pregnancy and breastfeeding in 2019 and 2020, respectively. To complement pregnancy label updates with patient-reported real-world data, this study examined German pregnancy and outcome reports including available data on child development from women with MS treated with peginterferon beta-1a or intramuscular (IM) interferon beta-1a. METHODS The post-authorisation safety study PRIMA included adult women diagnosed with relapsing-remitting MS or clinically isolated syndrome, who were treated with peginterferon beta-1a or IM interferon beta-1a before or during pregnancy and registered in the marketing authorisation holder's MS Service center patient support program. In the prospective part of the study, conducted from April to October 2021, data on developmental milestones of the newborns were collected via telephone interview from mothers reporting live births. RESULTS In total, 426 women were enrolled, reporting 542 pregnancies that resulted in 466 live births. A total of 162 women completed the questionnaire for 192 live births (53.1% male). Newborns had Apgar scores indicative of healthy infants. Weight, length and head circumference at birth and physical growth curves up to 48 months lay within the expected range of the German general population. Most newborn screenings and examinations during check-ups were inconspicuous over the study period of 48 months. Out of 158 breastfed infants, 112 (70.9%) were breastfed exclusively until month 5. CONCLUSION Study results confirmed former reports indicating that exposure to interferon beta therapies during pregnancy or lactation had no adverse effects on intrauterine growth and child development over the study period, which covered the first 4 years of life. These real-world data obtained within the scope of a patient support program for peginterferon beta-1a or IM interferon beta-1a corroborate German and Scandinavian registry data and support the label update of all interferon beta therapies.

Abstract
Family planning is essential for establishing Multiple Sclerosis (MS) prognosis, treatment decision, and disease monitoring. We aimed to generate an expert consensus addressing recommendations for family planning in MS patients of childbearing age. Initially, a committee comprising seven neurologists, experts in the MS field, identified the topics to be addressed. Then, the committee elaborated on different evidence-based preliminary statements. Next, using the Delphi methodology, a panel of neurologists manifested their level of agreement on the different statements using a Likert-type scale. Consensus was reached when ⩾70% of respondents expressed an agreement or disagreement using a five-point scale. Consensus was achieved on 47 out of 63 recommendations after three rounds of evaluations. The panel considered it essential to address family planning in all patients of childbearing age. There was also consensus that treatment should not be delayed due to the patient's desire for pregnancy. Additionally, in highly active patients, planning the pregnancy in the medium to long term using depletory drugs such as cladribine or alemtuzumab might represent a useful strategy. However, risks of adverse effects on the fetus due to drug-associated secondary autoimmunity should be addressed when alemtuzumab is considered. Moreover, the maintenance of natalizumab during pregnancy in very active patients reached expert consensus. Also, the panel supported the use of certain disease-modifying treatment (DMT) during lactation in selected cases. Our results identified specific areas of pregnancy planning in MS patients, where different treatment strategies might be considered to facilitate a safe and successful pregnancy while maintaining clinical and radiological stability.

NEUROLOGY(R) NEUROIMMUNOLOGY & NEUROINFLAMMATION 2023; 10:10/4/e200110. [PMID: 37217309 DOI: 10.1212/nxi.0000000000200110] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Accepted: 02/08/2023] [Indexed: 05/24/2023]
Abstract
BACKGROUND AND OBJECTIVE Discontinuation of fingolimod ≥2 months before pregnancy is recommended to minimize potential teratogenicity. The magnitude of MS pregnancy relapse risk, particularly severe relapses, after fingolimod cessation is unclear, as is whether this risk is reduced by pregnancy or modifiable factors. METHODS Pregnancies who stopped fingolimod treatment within 1 year before or during pregnancy were identified from the German MS and Pregnancy Registry. Data were collected through structured telephone-administered questionnaires and neurologists' notes. Severe relapses were defined as a ≥2.0 increase in Expanded Disability Status Scale (EDSS) or new or worsening relapse-related ambulatory impairment. Women who continued to meet this definition 1 year postpartum were classified as reaching the Severe Relapse Disability Composite Score (SRDCS). Multivariable models accounting for measures of disease severity and repeated events were used. RESULTS Of the 213 pregnancies among 201 women (mean age at pregnancy onset 32 years) identified, 56.81% (n = 121) discontinued fingolimod after conception. Relapses during pregnancy (31.46%) and the postpartum year (44.60%) were common. Nine pregnancies had a severe relapse during pregnancy and additional 3 during the postpartum year. One year postpartum, 11 of these (6.32% of n = 174 with complete EDSS information) reached the SRDCS. Adjusted relapse rates during pregnancy were slightly higher compared with the year before pregnancy (relapse rate ratio = 1.24, 95% CI 0.91-1.68). Neither exclusive breastfeeding nor resuming fingolimod within 4 weeks of delivery were associated with a reduced risk of postpartum relapses. Most pregnancies relapsed during the first 3 months postpartum (n = 55/204, 26.96%). DISCUSSION Relapses during pregnancy after fingolimod cessation are common. Approximately 6% of women will retain clinically meaningful disability from these pregnancy-related, fingolimod cessation relapses 1 year postpartum. This information should be shared with women on fingolimod desiring pregnancy, and optimizing MS treatment with nonteratogenic approaches should be discussed.

Abstract
The prevalence of chronic maternal disease is rising in the last decades in the developed world. Recent evidence indicated that the incidence of chronic maternal disease ranges from 10 to 30% of pregnancies worldwide. Several epidemiological studies in mothers with chronic diseases have mainly focused on the risk for adverse obstetric outcomes. Evidence from these studies supports a correlation between maternal chronic conditions and adverse perinatal outcomes, including increased risk for preeclampsia, cesarean section, preterm birth, and admission in the Neonatal Intensive Care Unit (NICU). However, there is a knowledge gap pertaining to the management of these women during lactation. This review aimed at summarizing the available research literature regarding breastfeeding in mothers with chronic diseases. Adjusted and evidence-based support may be required to promote breastfeeding in women with chronic diseases; however, our comprehension of breastfeeding in this subpopulation is still unclear. The literature related to breastfeeding extends in various scientific areas and multidisciplinary effort is necessary to compile an overview of current evidence and knowledge regarding breastfeeding issues in mothers with chronic diseases.

Mult Scler Relat Disord 2023; 75:104771. [PMID: 37245349 DOI: 10.1016/j.msard.2023.104771] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Revised: 05/05/2023] [Accepted: 05/21/2023] [Indexed: 05/30/2023]
Abstract
BACKGROUND Although the relapse risk is increased after birth in women with relapsing multiple sclerosis (RMS), only a very few disease-modifying therapies (DMTs) are approved during breastfeeding. Glatiramer acetate (GA, Copaxone®) is one of three DMTs that can be used in breastfeeding. The real-world safety of Copaxone® in Offsprings of Breastfeeding and treated RMS pAtients (COBRA) study demonstrated that offspring parameters (hospitalisations, antibiotic use, developmental delays, growth parameters) were similar between offspring breastfed by mothers taking GA or no DMT (control) during breastfeeding. COBRA data analyses were extended to provide further safety data on the impact of maternal GA treatment during breastfeeding on offspring. METHODS COBRA was a non-interventional, retrospective study using German Multiple Sclerosis and Pregnancy Registry data. Participants had RMS, gave birth and had GA or no DMT during breastfeeding. Offspring total adverse events (AEs), non-serious AEs (NAEs) and serious AEs (SAEs) up to 18 months postpartum were assessed. Reasons for offspring hospitalisations and antibiotic treatments were explored. RESULTS Baseline maternal demographics and disease characteristics were similar between cohorts. Each cohort had 60 offspring. Numbers of offspring AEs were comparable between cohorts; total AEs: 82 (GA) vs 83 (control); NAEs: 59 vs 61; SAEs: 23 vs 22. AEs in both cohorts were diverse with no specific patterns. Duration of GA-exposed breastfeeding was 6 to >574 days for offspring with any AE. For all-cause hospitalisations, 11 offspring had 12 hospitalisations (GA cohort) and 12 control offspring had 16 hospitalisations. Most common reason for hospitalisation was infection: 5/12 (41.7%; GA) vs 4/16 (25.0%, control). Two out of 12 (16.7%) hospitalisations due to infection occurred during GA-exposed breastfeeding; the others occurred 70, 192 and 257 days after discontinuation of GA-exposed breastfeeding. Median (range) duration of GA-exposed breastfeeding was 110 (56 to ≥285) days for offspring hospitalised for infections and 137 (88-396) days for those hospitalised for other reasons. Nine offspring had 13 antibiotic treatments (GA cohort) and nine control offspring had 10 treatments. Ten out of 13 (76.9%) antibiotic treatments occurred during GA-exposed breastfeeding, of which four were primarily due to double kidney with reflux. Other antibiotic treatments occurred 193, 229 and 257 days after discontinuation of GA-exposed breastfeeding. CONCLUSIONS GA treatment of mothers with RMS during breastfeeding did not increase AEs, hospitalisations or antibiotic use in their offspring versus control offspring. These data support previous COBRA data that the benefit of maternal RMS treatment with GA during breastfeeding outweighs the potential, apparently low risk of untoward events, in their breastfed offspring.

Abstract
The use of high-efficacy disease-modifying therapies (DMTs) early in the course of multiple sclerosis (MS) has been shown to improve clinical outcomes and is becoming an increasingly popular treatment strategy. As a result, monoclonal antibodies, including natalizumab, alemtuzumab, ocrelizumab, ofatumumab, and ublituximab, are frequently used for the treatment of MS in women of childbearing age. To date, only limited evidence is available on the use of these DMTs in pregnancy. We aim to provide an updated overview of the mechanisms of action, risks of exposure and treatment withdrawal, and pre-conception counseling and management during pregnancy and post-partum of monoclonal antibodies in women with MS. Discussing treatment options and family planning with women of childbearing age is essential before commencing a DMT in order to make the most suitable choice for each individual patient.

Abstract
OBJECTIVES Ambiguity exists about the impact of multiple sclerosis (MS) on fertility and pregnancy. We explored female and male patients' experiences with MS regarding family planning to understand information needs and opportunities to improve informed decision-making. METHODS Semi-structured interviews were conducted with Australian female (n = 19) and male (n = 3) patients of reproductive age diagnosed with MS. Transcripts were analysed thematically, adopting a phenomenological approach. RESULTS Four main themes emerged: 'reproductive planning', revealing inconsistent experiences about pregnancy intention discussions with health care professionals (HCPs), and involvement in decisions about MS management and pregnancy; 'reproductive concerns', about the impact of the disease and its management; 'information awareness and accessibility', with participants generally reporting they had limited access to desired information and received conflicting information about family planning; and 'trust and emotional support', with continuity of care and engagement with peer-support groups about family planning needs valued. CONCLUSION Patients with MS want consistent engagement with HCPs regarding discussion of pregnancy intent and desire improvements in quality and accessibility of available resources and support services to address reproductive concerns. PRACTICE IMPLICATIONS Family planning conversations should be a part of routine care planning for MS patients and contemporary resources are required to support these discussions.

Androgens show sex-dependent differences in myelination in immune and non-immune murine models of CNS demyelination. Nat Commun 2023; 14:1592. [PMID: 36949062 PMCID: PMC10033728 DOI: 10.1038/s41467-023-36846-w] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Accepted: 02/20/2023] [Indexed: 03/24/2023] Open
Abstract
Neuroprotective, anti-inflammatory, and remyelinating properties of androgens are well-characterized in demyelinated male mice and men suffering from multiple sclerosis. However, androgen effects mediated by the androgen receptor (AR), have been only poorly studied in females who make low androgen levels. Here, we show a predominant microglial AR expression in demyelinated lesions from female mice and women with multiple sclerosis, but virtually undetectable AR expression in lesions from male animals and men with multiple sclerosis. In female mice, androgens and estrogens act in a synergistic way while androgens drive microglia response towards regeneration. Transcriptomic comparisons of demyelinated mouse spinal cords indicate that, regardless of the sex, androgens up-regulate genes related to neuronal function integrity and myelin production. Depending on the sex, androgens down-regulate genes related to the immune system in females and lipid catabolism in males. Thus, androgens are required for proper myelin regeneration in females and therapeutic approaches of demyelinating diseases need to consider male-female differences.

Potential Protective Role of Pregnancy and Breastfeeding in Delaying Onset Symptoms Related to Multiple Sclerosis. Medicina (B Aires) 2023; 59:medicina59030619. [PMID: 36984620 PMCID: PMC10057678 DOI: 10.3390/medicina59030619] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 03/04/2023] [Accepted: 03/09/2023] [Indexed: 03/22/2023] Open
Abstract
The impact of pregnancy and breastfeeding on the development and outcomes of Multiple sclerosis (MS) has been debated for decades. Since several factors can influence the evolution of the disease, the protective role of multiparity and breastfeeding remains uncertain, as well the role of hormone replacement therapy in the perimenopausal period. We report two cases of relatively late-onset MS in two parous women, who developed their first neurological symptoms after six and nine pregnancies, respectively. Both women breastfed each of their children for 3 to 12 months. One of them underwent surgical menopause and received hormone replacement therapy for 7 years before MS onset. We performed a systematic literature review to highlight the characteristics shared by women who develop the disease in similar conditions, after unique hormonal imbalances, and to collect promising evidence on this controversial issue. Several studies suggest that the beneficial effects of pregnancy and breastfeeding on MS onset and disability accumulation may only be realized when several pregnancies occur. However, these data on pregnancy and breastfeeding and their long-term benefits on MS outcomes suffer from the possibility of reverse causality, as women with milder impairment might choose to become pregnant more readily than those with a higher level of disability. Thus, the hypothesis that multiparity might have a protective role on MS outcomes needs to be tested in larger prospective cohort studies of neo-diagnosed women, evaluating both clinical and radiological features at presentation.

Pregnancy Is Associated with Impaired Transcription of Human Endogenous Retroviruses and of TRIM28 and SETDB1, Particularly in Mothers Affected by Multiple Sclerosis. Viruses 2023; 15:v15030710. [PMID: 36992419 PMCID: PMC10051116 DOI: 10.3390/v15030710] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 03/01/2023] [Accepted: 03/06/2023] [Indexed: 03/12/2023] Open
Abstract
Accumulating evidence highlights the pathogenetic role of human endogenous retroviruses (HERVs) in eliciting and maintaining multiple sclerosis (MS). Epigenetic mechanisms, such as those regulated by TRIM 28 and SETDB1, are implicated in HERV activation and in neuroinflammatory disorders, including MS. Pregnancy markedly improves the course of MS, but no study explored the expressions of HERVs and of TRIM28 and SETDB1 during gestation. Using a polymerase chain reaction real-time Taqman amplification assay, we assessed and compared the transcriptional levels of pol genes of HERV-H, HERV-K, HERV-W; of env genes of Syncytin (SYN)1, SYN2, and multiple sclerosis associated retrovirus (MSRV); and of TRIM28 and SETDB1 in peripheral blood and placenta from 20 mothers affected by MS; from 27 healthy mothers, in cord blood from their neonates; and in blood from healthy women of child-bearing age. The HERV mRNA levels were significantly lower in pregnant than in nonpregnant women. Expressions of all HERVs were downregulated in the chorion and in the decidua basalis of MS mothers compared to healthy mothers. The former also showed lower mRNA levels of HERV-K-pol and of SYN1, SYN2, and MSRV in peripheral blood. Significantly lower expressions of TRIM28 and SETDB1 also emerged in pregnant vs. nonpregnant women and in blood, chorion, and decidua of mothers with MS vs. healthy mothers. In contrast, HERV and TRIM28/SETDB1 expressions were comparable between their neonates. These results show that gestation is characterized by impaired expressions of HERVs and TRIM28/SETDB1, particularly in mothers with MS. Given the beneficial effects of pregnancy on MS and the wealth of data suggesting the putative contribution of HERVs and epigenetic processes in the pathogenesis of the disease, our findings may further support innovative therapeutic interventions to block HERV activation and to control aberrant epigenetic pathways in MS-affected patients.

Abstract
BACKGROUND AND OBJECTIVE Myelin-oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD) frequently initiates during childbearing years. This study investigated the impact of pregnancy and post-partum on MOGAD activity. METHODS Retrospective analysis of clinical and demographic data from a multicenter French cohort of adult patients with MOGAD. All adult female patients who had a pregnancy after disease onset or in the year before disease onset were included. The annualized relapse rate was evaluated in patients who had a pregnancy after disease onset, to evaluate the impact of pregnancy and post-partum on MOGAD course. RESULTS Twenty-five informative pregnancies after disease onset were identified. No relapse was recorded during these pregnancies and only three relapses occurred during the first 3 months post-partum. The annualized relapse rate decreased from 0.67 (95% confidence interval: 0.40-1.10) during the pre-pregnancy period to 0 (95% confidence interval: 0-0.21) during pregnancy and to 0.22 (95% confidence interval: 0.09-0.53) during the first year post-partum. Among 144 female patients in their childbearing age recorded in the database, 18 (12.5%) reported their first symptoms during pregnancy or in the 12 months post-partum. DISCUSSION Our study suggests a marked reduction of MOGAD relapse rate during pregnancy and the post-partum period. Prospective studies on the role of pregnancy and delivery in MOGAD course are needed.

Abstract
Multiple sclerosis is a disease that tends to affect women during their childbearing years. Although relapse risk decreases during pregnancy, patients should still be optimized on disease-modifying therapy before and after pregnancy to minimize gaps in treatment. Exclusive breastfeeding may reduce the chances of disease relapse postpartum, and many disease-modifying therapies are considered to be safe while breastfeeding. Treatments for other neuroimmunologic disorders such as neuromyelitis optica spectrum disorder, myelin oligodendrocyte glycoprotein antibody-associated disease, neurosarcoidosis, and central nervous system vasculitis may require rituximab before and prednisone or intravenous immunoglobulin therapy during pregnancy.

Abstract
BACKGROUND Pregnancy planning is a relevant issue in the management of Multiple Sclerosis (MS), which commonly involves women of childbearing age. Increased knowledge and a wider therapeutic scenario could have changed the approach of neurologists towards this topic over time. Our aim was to describe how pregnancy planning and management for women with MS have changed in the last 15 years. METHODS We retrospectively collected clinical data of female patients with relapsing-remitting MS (RRMS), referred to the Neurology Clinic of the University-Hospital "Policlinico G. Rodolico" of Catania, who became pregnant between 2005-2020. We compared data about MS and pregnancy between two time periods according to pregnancy onset (2005-2012; 2013-2020). RESULTS 190 patients with RRMS carried 253 pregnancies in the observation period. Women undergoing a pregnancy in the last period (2013-2020), as compared to women who had pregnancy in the first period (2005-2012), were older (p<0.01), more often treated before and during pregnancy with high-efficacy disease-modifying drugs (DMD) (p<0.001), and exhibited lower annualized relapse rates (ARR) before (p=0.01) and after pregnancy (p<0.001). CONCLUSION Results from our experience suggest that nowadays DMD are more frequently used in women of childbearing age, even during pregnancy, leading to a reduced ARR before and after delivery in absence of increased obstetric complications.

Abstract
The immunoprotective role of pregnancy in multiple sclerosis (MS) has been known for decades. Conversely, there has been rich debate on the topic of breastfeeding and disease activity in MS. In clinical practice, women are often offered to restart their disease-modifying drug (DMD) soon after delivery to maintain their relapse risk protection. Limited available information about peri-partum DMD safety can discourage women to choose breastfeeding, despite the World Health Organization's recommendation to breastfeed children for the first 6 months of life exclusively. New evidence is emerging about the protective role of exclusive breastfeeding on relapse rate. Research studies shed light on the hormonal and immunological mechanisms driving the risk of relapses during pregnancy and postpartum. Finally, case reports, real-world data, and clinical trials are increasing our knowledge of the safety of DMDs for the fetus and infant. While some DMDs must be avoided, others may be considered in highly active pregnant or lactating women with MS. This mini-review conveys recent evidence regarding the protective role of exclusive breastfeeding in MS and offers clinicians practical considerations for a patient-tailored approach.

Abstract
Background Relapsing-remitting multiple sclerosis (RRMS) affects predominantly young women within reproductive years. As an increased risk of relapses is known to occur during the post-partum period, it is important to consider treatment options. Aim Evaluate the effects of intravenous immunoglobulins (IVIg) to prevent post-partum relapses. Methods We prospectively followed 198 pregnant female RRMS patients, 67 treated with IVIg during pregnancy and the three months post-partum, and 131 untreated patients that served as controls. Results During the pre-gestation year, 41.4% were treated with immunomodulatory drugs, and 28.3% experienced a relapse. During pregnancy and the post-partum period, the number of relapsing patients significantly decreased in the IVIg group (37.3%, 10.4%, 8.9%, respectively, p = 0.0003), while no significant change was observed in the untreated group (23.7%, 17.6%, and 22.1%). During the three-month post-partum period, there were only mild and moderate relapses in the IVIg group, while in the untreated group, there were also severe relapses. Stepwise logistic regression that assessed the relation between three-month post-partum relapse and explanatory variables demonstrated that untreated patients had increased risk for post-partum relapse (odds ratio = 4.6, 95% CI [1.69, 12.78], p = 0.033). Conclusions IVIg treatment proved efficient to reduce the rate and severity of relapses during pregnancy and the three-month post-partum.

Abstract
OBJECTIVE The objective of this study was to develop evidence-based recommendations on pregnancy management for persons with multiple sclerosis (MS). BACKGROUND MS typically affects young women in their childbearing years. Increasing evidence is available to inform questions raised by MS patients and health professionals about pregnancy issues. METHODS The French Group for Recommendations in Multiple Sclerosis (France4MS) reviewed PubMed and university databases (January 1975 through June 2021). The RAND/UCLA appropriateness method was developed to synthesise the scientific literature and expert opinions on healthcare topics; it was used to reach a formal agreement. Fifty-six MS experts worked on the full-text review and initial wording of recommendations. A group of 62 multidisciplinary healthcare specialists validated the final proposal of summarised evidence. RESULTS A strong agreement was reached for all 104 proposed recommendations. They cover diverse topics, such as pregnancy planning, follow-up during pregnancy and postpartum, delivery routes, locoregional analgesia or anaesthesia, prevention of postpartum relapses, breastfeeding, vaccinations, reproductive assistance, management of relapses and disease-modifying treatments. CONCLUSION The 2022 recommendations of the French MS society should be helpful to harmonise counselling and treatment practice for pregnancy in persons with MS, allowing for better and individualised choices.

Abstract
The immune system plays a significant role in multiple sclerosis. While MS was historically thought to be T cell-mediated, multiple pieces of evidence now support the view that B cells are essential players in multiple sclerosis pathogenic processes. High-efficacy disease-modifying therapies that target the immune system have emerged over the past two decades. Anti-CD20 monoclonal antibodies selectively deplete CD20+ B and CD20+ T cells and efficiently suppress inflammatory disease activity. These monotherapies prevent relapses, reduce new or active magnetic resonance imaging brain lesions, and lessen disability progression in patients with relapsing multiple sclerosis. Rituximab, ocrelizumab, and ofatumumab are currently used in clinical practice, while phase III clinical trials for ublituximab have been recently completed. In this review, we compare the four anti-CD20 antibodies in terms of their mechanisms of action, routes of administration, immunological targets, and pharmacokinetic properties. A deeper understanding of the individual properties of these molecules in relation to their efficacy and safety profiles is critical for their use in clinical practice.

Sex Hormones as Key Modulators of the Immune Response in Multiple Sclerosis: A Review. Biomedicines 2022; 10:biomedicines10123107. [PMID: 36551863 PMCID: PMC9775368 DOI: 10.3390/biomedicines10123107] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 11/25/2022] [Accepted: 11/29/2022] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND A variety of autoimmune diseases, including MS, amplify sex-based physiological differences in immunological responsiveness. Female MS patients experience pathophysiological changes during reproductive phases (pregnancy and menopause). Sex hormones can act on immune cells, potentially enabling them to modify MS risk, activity, and progression, and to play a role in treatment. METHODS Scientific papers (published between 1998 and 2021) were selected through PubMed, Google Scholar, and Web of Science literature repositories. The search was limited to publications analyzing the hormonal profile of male and female MS patients during different life phases, in particular focusing on sex hormone treatment. RESULTS Both men and women with MS have lower testosterone levels compared to healthy controls. The levels of estrogens and progesterone increase during pregnancy and then rapidly decrease after delivery, possibly mediating an immune-stabilizing process. The literature examined herein evidences the neuroprotective effect of testosterone and estrogens in MS, supporting further examinations of their potential therapeutic uses. CONCLUSIONS A correlation has been identified between sex hormones and MS clinical activity. The combination of disease-modifying therapies with estrogen or estrogen plus a progestin receptor modulator promoting myelin repair might represent an important strategy for MS treatment in the future.

Abstract
Multiple sclerosis (MS) is most often diagnosed in women of childbearing age. Therefore, it is important to examine the impact of pregnancy on the course of MS and to enable patients to make decisions about motherhood based on reliable data. The main objective of this study was to assess the impact of pregnancy on the course of MS by comparing the frequency of MS-related hospitalizations during pregnancy and 40 weeks postpartum versus 40 weeks before pregnancy. We used administrative health claims to identify female patients with MS, their deliveries, and their MS-related hospital admissions and calculated the frequency of MS-related hospital admissions before, during, and after pregnancy. We observed that MS is diagnosed approximately three times less often during pregnancy than before or after pregnancy. The number of MS-related hospital admissions decreased during pregnancy, especially in the third trimester. In contrast with other studies, we did not observe an increased level of MS-related admissions postpartum. The number of hospitalizations reported with steroid injections and emergency department visits also decreased during pregnancy. Our results show that pregnancy has a protective effect on the course of MS.

Abstract
Multiple sclerosis (MS), Neuromyelitis optica spectrum disorder (NMOSD) and Myelin-Oligodendrocyte-Glycoprotein antibody associated disorder (MOGAD) are demyelinating disorders of the central nervous system (CNS) of autoimmune origin. Here, we summarize general considerations on sex-specific differences in the immunopathogenesis and hormonal influences as well as key clinical and epidemiological elements. Gender-specific issues are widely neglected starting with the lacking separation of sex as a biological variable and gender comprising the sociocultural components. As for other autoimmune diseases, female preponderance is common in MS and NMOSD. However, sex distribution in MOGAD seems equal. As in MS, immunotherapy in NMOSD and MOGAD is crucial to prevent further disease activity. Therefore, we assessed data on sex differences of the currently licensed disease-modifying treatments for efficacy and safety. This topic seems widely neglected with only fragmented information resulting from post-hoc analyses of clinical trials or real-world post-marketing studies afflicted with lacking power and/or inherent sources of bias. In summary, biological hypotheses of sex differences including genetic factors, the constitution of the immune system and hormonal influences are based upon human and preclinical data, especially for the paradigmatic disease of MS whereas specific data for NMOSD and MOGAD are widely lacking. Epidemiological and clinical differences between men and women are well described for MS and to some extent for NMOSD, yet, with remaining contradictory findings. MOGAD needs further detailed investigation. Sex-specific analyses of safety and efficacy of long-term immunotherapies need to be addressed in future studies designed and powered to answer the pressing questions and to optimize and individualize treatment.

Abstract
Importance Risk of relapse may be increased in the postpartum period of neuromyelitis optica spectrum disorder (NMOSD). Information regarding factors associated with pregnancy-related attacks is still lacking. Objectives To identify factors associated with pregnancy-related NMOSD attacks, investigate the integrated annualized relapse rate (ARR) and Expanded Disability Status Scale (EDSS) score in each phase of pregnancy, and summarize pregnancy outcomes and complications in patients with NMOSD. Data Sources An electronic search was performed in the MEDLINE, PubMed in-process and non-MEDLINE, EMBASE, Web of Science, and Cochrane databases using the OvidSP search platform, updated through December 30, 2021. Study Selection All published and unpublished studies in English were considered, covering all patients with NMOSD with an informative pregnancy. Data Extraction and Synthesis Two independent reviewers extracted the published data with a standardized procedure following MOOSE and PRISMA guidelines. The end points were calculated with the DerSimonian and Laird inverse variance (for random effects) method. Main Outcomes and Measures The primary outcome was the rate of pregnancies with pregnancy-related NMOSD attacks, measured by risk ratios (RRs). The mean differences (MDs) in ARR and EDSS scores between each phase of pregnancy, pregnancy outcomes, and complications were defined as the secondary outcomes. Results A total of 15 studies were analyzed, including 443 patients with NMOSD with 639 informative pregnancies. Patients receiving immunosuppressive treatment during pregnancy (RR, 0.43; 95% CI, 0.32-0.57; P < .001) and with older age at conception (RR, 0.67; 95% CI, 0.47-0.95; P = .02) had lower rates of pregnancy with pregnancy-related attacks. The increase in the ARR was highest in the first trimester after delivery compared with before pregnancy (MD, 1.28; 95% CI, 0.94-1.62; P < .001). The EDSS scores increased significantly both during pregnancy (MD, 0.44; 95% CI, 0.20-0.69; P < .001) and in the postpartum period (MD, 0.88; 95% CI, 0.51-1.26; P < .001) compared with before pregnancy. Conclusions and Relevance This systematic review and meta-analysis found that receiving immunosuppressive treatment during pregnancy and older age at conception were associated with reduced risk of pregnancy-related NMOSD attacks, which mostly occurred in the first trimester of the postpartum period, although more high-quality prospective studies are needed.

Abstract
BACKGROUND There are limited data on the safety of breast feeding during rituximab therapy. Our objective is to determine exposure from breast feeding and biological effects of rituximab in breastfed infants. METHODS In our case series of six mother-infant pairs, the nursing mothers with relapsing-remitting multiple sclerosis received rituximab during breast feeding. As part of clinical follow-up, six serial breast milk samples, and blood samples from both mothers and infants, were collected and analysed. RESULTS The median average rituximab concentration (Cavg) in breast milk was 0.04 µg/mL and the estimated relative infant dose (RID) was 0.07%. The highest measured concentration of rituximab in the breast milk samples was 0.25 µg/mL, giving an estimated RID of 0.26%.All infant serum rituximab concentrations were below 0.01 µg/mL. The CD19 +B cell count values were within the 10th- 90th percentiles of reported normal ranges in healthy infants. CONCLUSIONS We found minimal transfer of rituximab into breast milk and could not reliably detect levels of rituximab in infant serum. B cell counts in infants were unaffected.

Abstract
BACKGROUND No specific treatment has demonstrated its effectiveness to prevent post-partum relapses for multiple sclerosis (MS) women. OBJECTIVE To assess the effectiveness of preventive high-dose corticosteroids in the post-partum period by comparing two strategies: (1) no preventive treatment and (2) standardized preventive treatment. METHODS We selected five French Multiple Sclerosis centers using the same post-partum strategy for their patients-either high-dose steroids (treating centers TC) or no treatment (non-treating centers NTC). We included relapsing-remitting multiple sclerosis women who delivered between January 2007 and January 2017. Our primary outcomes were the time from delivery to first relapse, EDSS progression and MRI activity between patients of treating centers and non-treating centers, after propensity-score weighting. RESULTS 350 patients were included (116 from treating centers, 234 from non-treating centers). For both groups, the annualized relapse rate decreased during pregnancy (0.28 in treating centers and 0.34 in non-treating centers during the third trimester) and increased during the first post-partum trimester (0.45 and 0.69, respectively) with 11% and 14% (NS) of patients facing at least one relapse, respectively. Our primary outcomes were not statistically different between both groups. CONCLUSION This study provides class III evidence that systematic high-dose corticosteroids are not associated with a reduced inflammatory activity during the post-partum period in multiple sclerosis patients.

Abstract
Multiple sclerosis (MS) is a chronic, autoimmune, demyelinating disease of the central nervous system (CNS) that leads to axonal damage and accumulation of disability. Relapsing-remitting MS (RR-MS) is the most frequent presentation of MS and this form of MS is three times more prevalent in females than in males. This female bias in MS is apparent only after puberty, suggesting a role for sex hormones in this regulation; however, very little is known of the biological mechanisms that underpin the sex difference in MS onset. Experimental autoimmune encephalomyelitis (EAE) is an animal model of RR-MS that presents more severely in females in certain mouse strains and thus has been useful to study sex differences in CNS autoimmunity. Here, we overview the immunopathogenesis of MS and EAE and how immune mechanisms in these diseases differ between a male and female. We further describe how females exhibit more robust myelin-specific T helper (Th) 1 immunity in MS and EAE and how this sex bias in Th cells is conveyed by sex hormone effects on the T cells, antigen presenting cells, regulatory T cells, and innate lymphoid cell populations.

Abstract
Monoclonal antibodies have become a mainstay in the treatment of patients with relapsing multiple sclerosis (RMS) and provide some benefit to patients with primary progressive MS. They are highly precise by specifically targeting molecules displayed on cells involved in distinct immune mechanisms of MS pathophysiology. They not only differ in the target antigen they recognize but also by the mode of action that generates their therapeutic effect. Natalizumab, an [Formula: see text]4[Formula: see text]1 integrin antagonist, works via binding to cell surface receptors, blocking the interaction with their ligands and, in that way, preventing the migration of leukocytes across the blood-brain barrier. On the other hand, the anti-CD52 monoclonal antibody alemtuzumab and the anti-CD20 monoclonal antibodies rituximab, ocrelizumab, ofatumumab, and ublituximab work via eliminating selected pathogenic cell populations. However, potential adverse effects may be serious and can necessitate treatment discontinuation. Most importantly, those are the risk for (opportunistic) infections, but also secondary autoimmune diseases or malignancies. Monoclonal antibodies also carry the risk of infusion/injection-related reactions, primarily in early phases of treatment. By careful patient selection and monitoring during therapy, the occurrence of these potentially serious adverse effects can be minimized. Monoclonal antibodies are characterized by a relatively long pharmacologic half-life and pharmacodynamic effects, which provides advantages such as permitting infrequent dosing, but also creates disadvantages regarding vaccination and family planning. This review presents an overview of currently available monoclonal antibodies for the treatment of RMS, including their mechanism of action, efficacy and safety profile. Furthermore, we provide practical recommendations for risk management, vaccination, and family planning.

Abstract
Background The effects of pregnancy on multiple sclerosis (MS) inflammatory activity are not well described in women with moderate to severe disabilities. Objective To quantify the peripartum annualized relapse rate (ARR) in women with MS with an Expanded Disability Status Scale (EDSS) ≥ 3. Methods We performed a retrospective cohort study of 85 pregnancies in 74 subjects with preconception EDSS ≥ 3. We quantified peripartum ARR and tested for risk factors predictive of peripartum relapses, postpartum brain magnetic resonance imaging activity (new T2 or gadolinium-enhancing lesions), and disability worsening. Results There were 74 live births, with a 56% operative delivery rate. In subjects with relapsing-remitting MS, ARR decreased to 0.11 during the third trimester of pregnancy compared to 0.59 in the year preconception and increased to 1.22 in the 3 months postpartum. Women with a higher preconception EDSS had higher odds of postpartum relapses and clinically significant worsening of disability as compared to subjects with a lower EDSS. Conclusions Moderately to severely disabled women with MS have a lower risk of relapse during pregnancy as compared to preconception, followed by a marked increase postpartum. Further studies are needed to identify ways to reduce peripartum inflammatory activity and disability progression in women with MS with moderate to severe disability.

Abstract
Background and purpose Sex differences in multiple sclerosis (MS) prevalence and disease course are thought to be driven by hormones. Exogenous exposure to estrogens may affect MS disease course. Thus, our aim was to investigate the association between hormone therapy (HT) and disease activity and disability accrual among women with MS. Methods A register‐based cohort study was conducted with prospectively enrolled cases from the Danish MS registry. Information on hormone exposure was retrieved from the National Prescription Registry. Outcomes were relapse rate, relapse rate ratio, recurrent relapses, 6‐month confirmed and sustained Expanded Disability Status Scale (EDSS) milestones 4 and 6, and recurrent EDSS worsening. Results In all, 3325 women were eligible for analyses, of whom 333 (10%) were ever on HT at some time during follow‐up. We found no association between HT and disability accrual, although a trend for increasing risk with increasing length of use was seen. The risk of reaching 6‐month confirmed and sustained EDSS 4 among users was 0.6 (95% confidence interval [CI] = 0.3–1.2) after <1 year of use and 1.4 (95% CI = 0.9–2.2) after >5 years of HT compared to never use. The risk of recurrent relapse was increased by 20% (95% CI = 1.0–1.4) among current users of HT compared to nonusers. However, the risk of recurrent relapses was driven by the first calendar period (1996–2005) before the introduction of high‐efficacy disease‐modifying therapy. Conclusions Our findings from this nationwide MS population suggest that HT does not affect disability accrual in women with MS, especially if used for <5 years.

Abstract
Multiple sclerosis (MS) is a debilitating degenerative disease characterized by an immunological attack on the myelin sheath leading to demyelination and axon degeneration. Mesenchymal stem/stromal cells (MSCs) and secreted extracellular vesicles (EVs) have become attractive targets as therapies to treat neurodegenerative diseases such as MS due to their potent immunomodulatory and regenerative properties. The placenta is a unique source of MSCs (PMSCs), demonstrates "fetomaternal" tolerance during pregnancy, and serves as a novel source of MSCs for the treatment of neurodegenerative diseases. PMSCs and PMSC-EVs have been shown to promote remyelination in animal models of MS, however, the molecular mechanisms by which modulation of autoimmunity and promotion of myelination occurs have not been well elucidated. The current review will address the molecular mechanisms by which PMSC-EVs can promote remyelination in MS.

Abstract
Background: Evidence guiding personalized decision-making with respect to disease-modifying therapy (DMT) around pregnancy in relapsing multiple sclerosis (RMS) is lacking. Objective: To generate and validate a risk score for disease reactivation intrapartum and postpartum in RMS. Methods: From the Vienna Innsbruck MS database (VIMSD), we included 343 pregnancies in patients with RMS. Primary endpoint was disease reactivation. Patients were randomly assigned 2:1 in a generation and validation dataset. A predictive score was calculated using the Cox regression and validated. Results: In the generation dataset, occurrence of relapse and type of DMT in the year before conception, DMT washout duration, the Expanded Disability Status Scale (EDSS) at conception, and time until DMT restart postpartum were identified as independent predictors of disease reactivation (p < 0.001). The resulting 10-point risk score robustly predicted reactivation (explaining 75% of variance, p < 0.001) identifying patients at high [≥6 points; mean risk 65%; range 50–100%; hazard ratio (HR) 14.5], intermediate (3–5 points; mean risk 24%; range 15–35%; HR 4.3), and low risk (≤2 points; mean risk 6%; range 0–8%) of disease reactivation in pregnancy and up to 6 months postpartum. Conclusion: The composite Vienna Innsbruck Pregnancy Risk in Multiple Sclerosis (VIPRiMS) score is a valuable clinical tool to support patients and neurologists in anticipating risk and, thus, individualizing treatment decision-making around pregnancy.

Abstract
Multiple sclerosis (MS) is a chronic immune-mediated, inflammatory, and degenerative disease that is up to three times more frequent in young women. MS does not alter fertility and has no impact on fetal development, the course of pregnancy, or childbirth. The Pregnancy in Multiple Sclerosis Study in 1998 showed that pregnancy, mostly in untreated women, did not adversely affect MS, as disease activity decreased during pregnancy (although it significantly increased in the first trimester postpartum). These findings, together with the limited information available on the potential risks of fetal exposure to disease modifying treatments (DMTs), meant that women were advised to delay the onset of DMTs, stop them prior to conception, or, in case of unplanned pregnancy, discontinue them when pregnancy was confirmed. Now, many women with MS receive DMTs before pregnancy and, despite being considered a period of MS stability, up to 30% of patients could relapse in the first trimester postpartum. Factors associated with an increased risk of relapse and disability during pregnancy and postpartum include relapses before and during pregnancy, a greater disability at the time of conception, the occurrence of relapses after DMT cessation before conception, and the use of high-efficacy DMTs before conception, especially natalizumab or fingolimod. Strategies to prevent postpartum activity are needed in some patients, but consensus is lacking regarding the therapeutic strategies for women with MS of a fertile age. This, along with the increasing number of DMTs, means that the decision-making processes in aspects related to family planning and therapeutic strategies before, during, and after pregnancy are increasingly more complex. The purpose of this review is to provide an update on pregnancy-related issues in women with MS, including recommendations for counseling, general management, use of DMTs in pre-pregnancy, pregnancy, and postpartum periods, and breastfeeding-related aspects of DMTs.

Abstract
BACKGROUND The effect of pregnancy on brain changes and radiological disease activity in women with multiple sclerosis (MS) is not well understood. AIMS To describe the dynamic of lesion activity and brain volume changes during the pregnancy and postpartum periods. METHODS This observational study of 62 women with relapsing-remitting MS included MRI (221 scans) as well as clinical visits at baseline (<24 and >6 months before), prepregnancy (<6 months before), postpartum (<3 months after), and the follow-up (>12 and <24 months after delivery) period. RESULTS The majority of women had a mild disability and a short disease duration (median 5.5 years). Eighteen (29.0%) women had a relapse during the year preceding pregnancy onset, 9 (14.5%) during pregnancy, and 20 (32.3%) in the year following delivery. Disability status remained unchanged during follow-up. Women in the postpartum period (n=62) had higher T2 lesion volume (median: 0.94 ml vs. 1.18 ml), greater annualized T2 lesion volume increase (0.0 ml vs. 0.23 ml), lower brain parenchymal fraction (86.4% vs. 85.6%) and greater annualized brain volume loss (-0.16% vs. -1.74%) compared with the prepregnancy period (all p<0.001). At 12-24 months after delivery women (n=41) had higher T2 lesion volume (1.0 ml vs. 1.16 ml) and lower brain parenchymal fraction (86.5% vs. 86.0%) compared to the prepregnancy period (both p<0.001). CONCLUSIONS The postpartum period was associated with an increase in T2 lesion volume and accelerated brain volume loss in a considerable proportion of women. This should be considered in treatment decision-making and designing clinical trials.
