Abstract
Background Pregnancies in women with pre-existing medical conditions are on the rise. These pregnancies are characterized by an increased rate of maternal and perinatal complications, which can result in higher health care expenditures and altered pregnancy experiences. The purpose of this study is to integrally analyze maternity care for women with pre-existing conditions in the framework of a risk-adapted, interdisciplinary care by recording three substantial parts of maternity care: (1) maternal and perinatal outcome; (2) hospital costs and reimbursements covering the period from preconception counseling or initial antenatal visit to discharge after birth; and (3) women's experience of reproductive choice and becoming a mother in the presence of a pre-existing condition. Methods In this observational, prospective, longitudinal, and monocentric cohort study, we aim to include a total of 1,500 women over a recruitment period of 15 months. Women registering for care at the Department of Obstetrics and Prenatal Medicine, University Hospital Bonn, Germany, are allocated to three groups based on their health and risk status: women with pre-existing conditions, as well as healthy women with obstetric risk factor and healthy women with a low-risk pregnancy. Participants are observed from time of initial consultation until discharge after birth. Analysis focuses on (1) maternal and perinatal outcome, especially rate of severe maternal and neonatal morbidity; (2) costs and reimbursements; and (3) surveys to capture of women's experience and health-related quality of life during the time of reproductive choice, pregnancy, and childbirth in the presence of pre-existing medical conditions. Discussion With its complex three-dimensional design, the ForMaT-Trial is aiming to provide a comprehensive analysis of pregnancy and childbirth in women with pre-existing conditions. The results may serve as a basis for counseling and care of these women. By analyzing costs of specialized care, data for discussing reimbursement are generated. Lastly, our results may increase awareness for the perception of reproductive choice, pregnancy and motherhood in this continuously rising population.Clinical trial registration: German Clinical Trials Register, DRKS00030061, October 28, 2022.

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.

Assessing the Risk of Relapse Requiring Corticosteroids After In Vitro Fertilization in Women With Multiple Sclerosis. Neurology 2022; 99:e1916-e1925. [PMID: 35953288 DOI: 10.1212/wnl.0000000000201027] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Accepted: 06/13/2022] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND AND OBJECTIVES Several studies have shown an increased risk of relapse after in vitro fertilization (IVF) in women with multiple sclerosis (MS), especially when a gonadotrophin-releasing hormone (GnRH) agonist stimulation protocol was used. Our objective was to investigate the risk of relapse after IVF in women with MS, overall and according to stimulation protocol (GnRH agonists vs antagonists), using data from the French national health insurance database. METHODS This retrospective cohort study included all women with MS who have benefited from IVF between January 1, 2010, and December 31, 2015, in France. Three-month exposed periods after IVF were compared with unexposed periods before IVF, each woman being her own control. Four outcomes were considered: annualized relapse rate (ARR), proportion of IVF with relapse, difference in the number of relapses "after-before," and the delay from IVF to the first relapse. Relapses were identified by an algorithm based on MS-related hospital admissions and the use of corticosteroid therapy. Stimulation protocols and disease-modifying therapies (DMTs) were identified using drug claims. Zero-inflated Poisson regression models adjusted for age at IVF and the presence of DMT were used. A random effect on women was included because women may undergo multiple IVF procedures. Subgroup analyses by stimulation protocol and IVF outcome (pregnancy or failure) were conducted. RESULTS A total of 225 women accounting for 338 IVF procedures were included (the mean age at the first IVF 34.6 ± 4.5 years; 36% of women underwent at least 2 IVF procedures during the period). No increase in the risk of relapse after IVF was found overall (before vs after IVF: 0.20 vs 0.18 relapse per patient-year; 7.7% vs 7.1% of IVF with women having at least one relapse) and in subgroups. A lower ARR before and after IVF was observed among women who remained treated until IVF. DISCUSSION The maintenance of DMT until IVF seemed to be a determining factor in reducing the risk of relapse. Women with MS should be reassured because we did not show an increased risk of relapse requiring the use of corticosteroid therapy after IVF neither with GnRH agonists nor with GnRH antagonists.

Abstract
OBJECTIVE Assessing the risk of clinical and radiological reactivation during pregnancy and post partum in women with multiple sclerosis (MS) treated with natalizumab (NTZ) throughout pregnancy (LONG_EXP) compared with women interrupting treatment before (NO_EXP) and within >-30 days and ≤90 days from conception (SHORT_EXP), and describing newborns' outcomes. METHODS Maternal clinical and radiological outcomes and obstetric and fetal outcomes were retrospectively collected and compared among groups (NO_EXP, SHORT_EXP, LONG_EXP). Predictors of clinical and radiological reactivation were investigated through univariable and multivariable analysis. RESULTS 170 eligible pregnancies from 163 women referring to 29 Italian MS centres were included. Annualised relapse rate (ARR) was significantly lower in LONG_EXP (n=66, 0.02 (0.001-0.09)) compared with NO_EXP (n=31, 0.43 (0.21-0.75), p=0.002) and SHORT_EXP (n=73, 0.46 (0.30-0.66), p=0.0004) during pregnancy, and in LONG_EXP (0.12 (0.05-0.24)) compared with SHORT_EXP (0.30 (0.17-0.50), p=0.008) during post partum. Gadolinium-enhancing (Gd+) lesions were less frequent in LONG_EXP (n=6/50, 2.00%) compared with NO_EXP (n=9/21, 42.86%) and SHORT_EXP after delivery (n=17/49, 34.69%, p=0.010).Delaying NTZ resumption after delivery significantly increased the risk of relapses (OR=1.29 (95% CI 1.07 to 1.57), p=0.009) and Gd+ lesions (OR=1.49 (95% CI 1.17 to 1.89, p=0.001). Newborns' weight, length, head circumference and gestational age did not differ among groups after adjusting for confounders. Anaemia was tracked in 4/69 LONG_EXP newborns. Congenital anomaly rate was within the expected range for the untreated MS population. CONCLUSIONS Our findings indicate that in women with MS treated with NTZ before conception, continuation of NTZ throughout pregnancy and its early resumption after delivery mitigate the risk of clinical and radiological reactivation. This approach has no major impact on newborns' outcomes.

Abstract
Objectives: Multiple sclerosis (MS) and neuromyelitis optica spectrum disorders (NMOSD) predominantly affect women of reproductive age. During the last few decades many disease-modifying therapies (DMTs) have been approved. It is therefore important to provide epidemiological structures for the collection of safety information on exposed pregnancies. Data on disease activity after withdrawal of DMTs are in high demand especially as severe relapses have been described after ceasing highly effective DMTs. Although breastfeeding is recommended, it is still unclear if the early reintroduction, especially of highly effective DMTs, has a beneficial effect on postpartum relapse risk or a combination of both, however safety data are lacking. Methods: The German MS and Pregnancy Registry (DMSKW) is a nationwide, observational, cohort study of pregnant women with MS or NMOSD, founded in 2006. As the study procedure has undergone important adaptation in recent years, described here is the updated methodology including data source and acquisition as well as variables collected within the DMSKW. Results: As of December 2020, the DMSKW database comprises 2579 pregnancies, 2568 with MS and 11 with NMOSD. Women are enrolled at a median gestational week of 11 (range: 0.02–42.1), have a median postpartum follow up of 1.2 years (range: 0–9.2) with 76% of all pregnancies being exposed to a DMT, mostly in the first trimester. Spontaneous abortion and preterm birth occurred in 7% and 10%, respectively; 19% of all women suffered from at least one relapse during pregnancy, with a minimum of 6% during the third trimester of pregnancy. Conclusion: The DMSKW is a valuable structure in providing safety data on drug exposure during pregnancy and lactation in combination with information on disease activity up to 6 years postpartum. This article will be the reference for describing the methods of future publications from the DMSKW.

Abstract
Pregnancy presents the maternal immune system with a unique immunological challenge since it has to defend against pathogens while tolerating paternal allo-antigens expressed by fetal tissues. T helper (Th) cells play a central role in modulating immune responses and recent advances have defined distinct contributions of various Th cell subsets throughout each phase of human pregnancy, while dysregulation in Th responses show association with multiple obstetrical complications. In addition to localized decidual mechanisms, modulation of Th cell immunity during gestation is mediated largely by oscillations in sex hormone concentrations. Aberrant Th cell responses also underlie several autoimmune disorders while pregnancy-induced changes in the balance of Th cell immunity has been shown to exert favorable outcomes in the progression Th1 and Th17 driven autoimmune conditions only to be followed by post-partal exacerbations in disease.

Abstract
BACKGROUND Multiple sclerosis (MS) is an inflammatory demyelinating chronic neurological disease that affects the central nervous system of young adults and their quality of life. Several studies have investigated the effects of pregnancy and breastfeeding on MS. However, the evidence regarding the influence of pregnancy and breastfeeding on MS is still accumulating. This review aimed to summarize the current evidence regarding the effects of pregnancy and breastfeeding on MS. SUMMARY A systematic electronic literature search of the PubMed and Embase databases was conducted to determine relevant published articles. The eligible studies were summarized and evaluated in tables. Key Messages: The majority of the studies indicated that pregnancy appears to lower the rate of MS relapses, particularly in the third trimester. The evidence regarding the effect of breastfeeding on MS remains inconsistent. Despite reports of negative obstetric outcomes in some pregnant women with MS, pregnancies in women with MS should not be categorized as high-risk pregnancies.

J Comp Eff Res 2021; 10:175-186. [PMID: 33565886 DOI: 10.2217/cer-2020-0211] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/21/2022] Open
Abstract
Background: Although previous cohort studies of women with multiple sclerosis (MS) yielded a reduction in relapse rate during pregnancy, the effect size has not been quantified in a comprehensive manner. In addition, the effects on disability progression and peripartum outcomes have been controversial. The purpose of this work is to assess the effect of pregnancy on disease activity, and to assess the effects of MS on pregnancy as well. Materials & methods: We searched in PubMed, Cochrane Library and EMBASE for cohort studies dealing with the effects of pregnancy on relapse rates, disability progression and peripartum outcomes in women with MS. The evaluated outcomes were: changes in the annualized relapse rate (ARR) in pregnancy and puerperium, disability worsening compared with the year before pregnancy, and peripartum outcomes, which were compared with the ones of non-MS women. In the majority of cohorts included here, the women were not under disease modifying therapies during pregnancy. Results: We found 23 cohort studies measuring changes in the ARR during pregnancy and puerperium; 12 were prospective and 11 retrospective. In 17 cohorts there was significant reduction in the ARR during pregnancy compared with prepregnancy period. The pooled mean reduction in the ARR was -0.5 (95% CI: 0.67-0.38), p < 0.001, from 15 cohorts included in meta-analysis. In 18 cohorts the ARR increased in the 3-month puerperium relative to prepregnancy year period; the pooled mean increase in the ARR was 0.22 (95% CI: 0.11-0.33), p < 0.001, from 14 cohorts included in meta-analysis. Disability worsening was addressed in 18 cohorts, and in 14 of them there were no significant changes. Peripartum complications and obstetrical outcomes were assessed in 16 cohorts, of whom 13 were retrospective, without finding significant differences. Conclusion: Pregnancy is associated with lower disease activity, and puerperium with higher disease activity. Disability does not change significantly after pregnancy. The obstetrical outcomes are not very different from those of non-MS women in most cohorts.

Abstract
Background: Multiple sclerosis (MS) is an inflammatory and demyelinating disease of the central nervous system with a variable natural history of relapse and remission. Previous studies have found many differentially expressed genes (DEGs) in the peripheral blood of MS patients and healthy controls, but the value of these genes for predicting the risk of relapse remains elusive. Here we develop and validate an effective and noninvasive gene signature for predicting relapse-free survival (RFS) in MS patients. Methods: Gene expression matrices were downloaded from Gene Expression Omnibus and ArrayExpress. DEGs in MS patients and healthy controls were screened in an integrated analysis of seven data sets. Candidate genes from a combination of protein–protein interaction and weighted correlation network analysis were used to identify key genes related to RFS. An independent data set (GSE15245) was randomized into training and test groups. Univariate and least absolute shrinkage and selection operator–Cox regression analyses were used in the training group to develop a gene signature. A nomogram incorporating independent risk factors was developed via multivariate Cox regression analyses. Kaplan–Meier methods, receiver-operating characteristic (ROC) curves, and Harrell's concordance index (C-index) were used to estimate the performance of the gene signature and nomogram. The test group was used for external validation. Results: A five-gene signature comprising FTH1, GBP2, MYL6, NCOA4, and SRP9 was used to calculate risk scores to predict individual RFS. The risk score was an independent risk factor, and a nomogram incorporating clinical parameters was established. ROC curves and C-indices demonstrated great performance of these predictive tools in both the training and test groups. Conclusions: The five-gene signature may be a reliable tool for assisting physicians in predicting RFS in clinical practice. We anticipate that these findings could not only facilitate personalized treatment for MS patients but also provide insight into the complex molecular mechanism of this disease.

Abstract
Multiple sclerosis (MS) is usually diagnosed between twenty and forty years of age, when people often plan to have children. A lot has been said about the effect of pregnancy on the course of MS. The individual factors responsible for the disease modifying effect of pregnancy are not well determined. Having MS neither affects the fertility or the course of pregnancy itself. During pregnancy, many women find that their symptoms stay the same or even improve. Epidural and spinal analgesia appear to be safe and in general are not contraindicated for patients with MS. The management of disease-modifying treatments (DMTs) in pregnancy is a new issue for consideration in the clinical practice. There is limited information available into the safety of DMT use during pregnancy, especially for the most recent ones. In general, discontinuation of DMTs is recommended before conception to minimize risk of fetal harm. Women with very active MS before pregnancy who stop second-line treatments may show an increase in disease activity during pregnancy. Therefore, it might be discussed to maintain patients on DMTs until pregnancy is confirmed, and sometimes throughout pregnancy, to avoid a rebound of disease activity and severe relapses during pregnancy in very active patients.

Abstract
Objective: To review the current evidence regarding pregnancy-related issues in multiple sclerosis (MS) and to provide recommendations specific for each of them. Research design and methods: A systematic review was performed based on a comprehensive literature search. Results: MS has no effect on fertility, pregnancy or fetal outcomes, and pregnancies do not affect the long-term disease course and accumulation of disability. There is a potential risk for relapse after use of gonadotropin-releasing hormone agonists during assisted reproduction techniques. At short-term, pregnancy leads to a reduction of relapses during the third trimester, followed by an increased risk of relapses during the first three months postpartum. Pregnancies in MS are not per se high risk pregnancies, and MS does not influence the mode of delivery or anesthesia unless in the presence of significant disability. MRI is not contraindicated during pregnancy; however, gadolinium contrast media should be avoided whenever possible. It is safe to use pulse dose methylprednisolone infusions to manage acute disabling relapses during pregnancy and breastfeeding. However, its use during the first trimester of pregnancy is still controversial. Women with MS should be encouraged to breastfeed with a possible favorable effect of exclusive breastfeeding. Disease-modifying drugs can be classified according to their potential for pregnancy-associated risk and impact on fetal outcome. Interferon beta (IFNβ) and glatiramer acetate (GA) may be continued until pregnancy is confirmed and, after consideration of the individual risk-benefit if continued, during pregnancy. The benefit of continuing natalizumab during the entire pregnancy may outweigh the risk of recurring disease activity, particularly in women with highly active MS. GA and IFNβ are considered safe during breastfeeding. The use of natalizumab during pregnancy or lactation requires monitoring of the newborn. Conclusions: This review provides current evidence and recommendations for counseling and management of women with MS preconception, during pregnancy and postpartum.

Abstract
Pregnancy influences the course of neuroimmunologic conditions, which include multiple sclerosis (MS), neuromyelitis optica spectrum disorder, and autoimmune encephalitis. The outcomes differ significantly for each disorder, reflecting the impact of hormonal changes, T-cell subsets, and placental factors on disease pathogenesis. In recent years, numerous data have emerged regarding MS activity throughout pregnancy and postpartum. Historically, the misconception that pregnancy worsens MS outcomes led patients to abstain from childbearing. Now, more women with these disorders, empowered by up-to-date information and better baseline disease control, are choosing to conceive. Nevertheless, the management of MS and related disorders in the pregnancy and postpartum period is complicated and requires a nuanced approach. Since standardized treatment guidelines around pregnancy are currently lacking, neurologists, together with obstetricians, must engage patients in a shared decision-making process that weighs the benefits to the mother and risks to the fetus. This chapter outlines the pathophysiology of neuroimmunologic disorders during pregnancy and postpartum, the impact of these diseases on childbearing, including fertility, pregnancy, delivery, and peurperium, as well as existing recommendations for treatment.

Abstract
BACKGROUND Some studies have looked at the age at menarche and risk of Multiple Sclerosis (MS).We aimed to conduct a systematic review and meta-analysis to estimate a pooled odds ratio of developing MS by increasing age at menarche. METHODS We searched PubMed, Scopus, EMBASE, CINAHL, Web of Science, Ovid, google scholar and gray literature (references of references, congress abstracts) up to 10th April 2019. RESULTS The literature search found 312 articles. After eliminating duplicates, reviews, case reports and trials, 18 articles remained. Three articles were ultimately included in the final analysis. Two studies were from Iran, and one from Canada. The pooled odds ratio (OR) for increasing 1 year of age at menarche was 0.88 (95% CI:0.82-0.94), with no significant heterogeneity (I2 = 49%, p = 0.1). Mean age at menarche was significantly different between case and control groups (mean difference = - 0.22, 95% CI = -0.42,-0.02). CONCLUSION The result of this systematic review showed that the risk of MS decreases by increasing age at menarche.

Abstract
Multiple sclerosis (MS) and neuromyelitis optica (NMO) are chronic inflammatory demyelinating disorders of the central nervous system that often affect women during childbearing years. Therefore, issues of conception, pregnancy, and delivery are of significant importance to patients and treating physicians. The current review provides updated information regarding the effects of pregnancy on MS and NMO, as well as the available safety data on immunomodulatory MS therapies for pregnant and lactating women. Management issues of women with MS and NMO during conception, gestation, and the postpartum period also are addressed.

Abstract
Objective To evaluate relapse rates and disease-modifying drug (DMD) treatment in US women with multiple sclerosis (MS) and a live birth. Methods This retrospective administrative claims database study used US commercial health plan data from women with MS and a live birth from January 1, 2006, to June 30, 2015. Relapses and DMD treatment were evaluated 1-year prepregnancy, during pregnancy, during puerperium (6 weeks postpregnancy), and 1-year postpregnancy. Relapse was defined as MS-related hospitalization, emergency room visit, or outpatient visit with corticosteroid prescription within 7 days. Generalized estimating equation models for longitudinal data tested for differences between prepregnancy vs the other time periods. Results A total of 2,158 patients were eligible. The odds of relapse declined during pregnancy (odds ratio [OR] 0.623, 95% confidence interval [CI] 0.521–0.744; p < 0.0001), increased during puerperium (OR 1.710, 95% CI 1.358–2.152; p < 0.0001), and ended at a higher level during the last 3 postpartum quarters (OR 1.216, 95% CI 1.052–1.406; p = 0.0081). The proportion of women with DMD treatment was rather low overall: approximately 20% prepregnancy, bottoming to 1.9% during the second trimester, and peaking at 25.5% 9 to 12 months postpartum. DMD treatment declined significantly during pregnancy (OR 0.171, 95% CI 0.144–0.203; p < 0.0001), remained lower during puerperium (OR 0.361, 95% CI 0.312–0.418; p < 0.0001), and ended at a higher level during the last 3 postpartum quarters (OR 1.259, 95% CI 1.156–1.371; p < 0.0001). Conclusions The rate of MS relapse decreased during pregnancy, increased 6 months postpartum, and decreased 6 to 12 months postpartum. DMD treatment was uncommon in the year before pregnancy, further decreased immediately prepregnancy and during pregnancy, and increased postpartum.

Abstract
PURPOSE OF REVIEW This article provides a review of the available data on reproductive issues that arise in patients with multiple sclerosis (MS). RECENT FINDINGS Recent findings have replicated earlier findings that pregnancy and possibly breast-feeding bring about a favorable immunomodulatory effect in patients with MS. Use of disease-modifying therapies prior to pregnancy may further decrease a patient's risk for postpartum disease activity. SUMMARY The annualized relapse rate in MS decreases during pregnancy, with a nadir in the third trimester, and rebounds significantly in the 3-month postpartum period. Exclusive breast-feeding may exert a beneficial effect in decreasing the postpartum risk for relapse. Certain assisted reproductive technology methods are thought to increase the risk for relapse. Disease-modifying therapies are generally discontinued during pregnancy and lactation with a few exceptions. The pregnancy course is usually routine without significant obstetric complications, and babies, although slightly smaller, are typically healthy.

Abstract
INTRODUCTION Women with multiple sclerosis (MS) are treated early in the disease course with disease modifying therapies (DMT). Updated information is needed on pregnancy outcomes of DMT-exposed pregnancies and the effect of the drug withdrawal on MS disease activity. Areas covered: In this review, we will cover the most important updated management strategies in planning a pregnancy when having MS. Expert opinion: MS itself does not increase the risk of adverse pregnancy outcomes and does not negatively influence the long-term course of the disease. As MS became a treatable disease, management of DMTs before, during and after pregnancy is important. This requires updated knowledge on safety of DMTs as well as data of the effect on disease activity after drug withdrawal. A special challenge is the handling of women with highly active MS, as pregnancy might not be powerful enough to suppress the risk of rebound relapses. Exclusive breastfeeding is an option for many women who want to do so, but in cases of high disease activity and those women who do not want to breastfeed, early reintroduction of MS therapies should be considered.

Abstract
OBJECTIVE The Lebanese Multiple Sclerosis (LeMS) study aims to assess the influence of pregnancy and delivery on the clinical course of multiple sclerosis (MS) in Lebanese women. SETTING This prospective multicentre study took place in three MS referral university medical centres in Lebanon. PARTICIPANTS Included were 29 women over 18 years who had been diagnosed with MS according to the McDonald criteria, and became pregnant between 1995 and 2015. Participating women should have stopped treatment 3 months before conception and become pregnant after the onset of MS. Women were followed up from 1 year preconceptionally and for 4 years postpartum. MAIN OUTCOME MEASURES The annualised relapse rates per participant during each 3-month period during pregnancy and each year postpartum were compared with the relapse rate during the year before pregnancy using the paired two-tailed t test. p Values <0.05 were considered statistically significant for all analyses (95% CI). RESULTS 64 full-term pregnancies were recorded. All pregnancies (100%) resulted in live births, with no complications or other diseases. In comparison with the prepregnancy year, in which the mean relapse rate±SE was 0.17±0.07, there was a significant reduction in the relapse rate during pregnancy and in the first year postpartum (p=0.02), but an increase in the rate in the second year postpartum (0.21±0.08). Thereafter, from the third year postpartum through the following fourth year, the annualised relapse rate fell slightly but did not differ from the annualised relapse rate recorded in the prepregnancy year (0.17±0.07). CONCLUSIONS Pregnancy in Lebanese women with MS does not seem to increase the risk of complications. No relapses were observed during pregnancy and in the first year postpartum; however, relapses rebounded in the second year postpartum, and over the long term, returned to the levels that preceded pregnancy.

Abstract
MS-pathogenesis involves both genetic-susceptibility and environmental determinants. Three (or more) sequential environmental-factors are implicated. The first acts near birth, the second acts during childhood/adolescence, and the third acts subsequently. Two candidate factors (vitamin D deficiency and Epstein-Barr viral infection) seem particularly well-suited to the first two environmental-events but other factors (e.g., obesity and smoking behavior) seem also to be involved in the causal scheme. MS-pathogenesis can be modeled by incorporating both the environmental and genetic-factors into a causal scheme, which can then help to explain some of the changes in MS-epidemiology (e.g., increasing disease-prevalence, changing sex-ratio, and regional-variations in monozygotic-twin-concordance-rates), which have been taking place recently. This model suggests that genetic-susceptibility is overwhelmingly the most important determinant of MS and that, at least, 92.5% of individuals (and likely much more) are, essentially, incapable of developing MS, regardless of their specific environmental-exposures. Nevertheless, the genetics is complex and the contribution of any specific gene to MS-susceptibility seems to be quite modest. Thus, even for the DRB1*1501 allele (the strongest known MS-susceptibility marker), most carriers are not in the genetically-susceptible group. Moreover, 45-50% of individuals with MS lack this allele entirely and some of the haplotypes that carry this allele don't also confer any disease-risk. Finally, because the prevalence of genetic-susceptibility seems to be so similar throughout North America and Europe, and despite the crucial importance of a person's genetic make-up to disease pathogenesis, it is the environmental-factors, which largely responsible for the observed regional variations in disease-characteristics. Thus, despite MS being more common in women, men are more likely to be genetically-susceptible. This apparent paradox seems to relate to the fact that women are much more responsive than men to the recent changes in environmental-exposure (whatever these have been). These gender-differences may help to explain changes in the sex-ratio and the increasing disease-prevalence, which have both been observed recently. The potential importance of these conclusions regarding the role of environment in MS-pathogenesis is that they open the door to the possibility of pursuing strategies for primary primary disease prevention in the future.

Abstract
Multiple sclerosis (MS) is a recurrent inflammatory disease of the central nervous system, which ultimately causes substantial disability in many patients. A key clinical feature of this disease is the occurrence of relapses, consisting of episodes of neurological dysfunction followed by periods of remission. This review considers in detail the importance of the occurrence of relapses to the ultimate course of MS and the impact of relap setreatment (both acutely and prophylactically) on the long-term outcome for individuals. The ultimate goal of therapy in MS is the reduction of long-term disability. Clinical trials in MS, however, typically only extend for a very short time period compared to the time it takes for disability to evolve. Consequently, short-term outcome measures that are associated with, and predict, future disability need to be identified. In this regard, not only are relapses a characteristic feature of MS, they have also been proven to be associated with the occurrence of long-term disability. Moreover, treatments that reduce the number and severity of these attacks improve the long-term prognosis.

Abstract
OBJECTIVE To examine the evidence guiding management of multiple sclerosis (MS) in reproductive-aged women. DATA SOURCES We conducted an electronic literature search using PubMed, ClinicalTrials.gov, and other available resources. The following keywords were used: "multiple sclerosis" and "pregnancy." We manually searched the reference lists of identified studies. METHODS OF STUDY SELECTION Two reviewers categorized all studies identified in the search by management topic, including effect of pregnancy on MS course, fetal risks associated with disease-modifying treatments during pregnancy, and management of patients off disease-modifying treatment. We categorized studies by strength of evidence and included prior meta-analyses and systematic studies. These studies were then summarized and discussed by an expert multidisciplinary team. TABULATION, INTEGRATION, AND RESULTS The risk of MS relapses is decreased during pregnancy and increased postpartum. Data are lacking regarding the risks of disease-modifying treatments during pregnancy. There may be an increased risk of MS relapses after use of assisted reproductive techniques. There does not appear to be a major increase in adverse outcomes in newborns of mothers with MS. CONCLUSION Although there are many unmet research needs, the reviewed data support the conclusion that in the majority of cases, women with MS can safely choose to become pregnant, give birth, and breastfeed children. Clinical management should be individualized to optimize both the mother's reproductive outcomes and MS course.

Abstract
The purpose of studying the epidemiology of multiple sclerosis (MS) is twofold. First, it is important to understand clearly the natural history of the illness in order to assist patients in making decisions about their future with respect to issues such as family planning, the importance of securing lifelong healthcare, their ability to get and maintain employment, and making appropriate choices of therapy for their particular circumstances. This is not to suggest that, even with the best possible information, the ultimate prognosis for any individual can be predicted with absolute accuracy. It cannot. Nevertheless, accurate information can be very helpful both to reassure patients that many individuals with MS do remarkably well in the long term (perhaps, especially, with current and future therapies) and also to empower individuals with respect to their ability to make their own life choices. Second, and arguably the more important purpose for studying the epidemiology of MS, is to gain insights to the underlying causes of the disease. Indeed, if the principal mechanisms of disease pathogenesis were to be understood clearly, then it might be possible to entertain notions of either a cure for existing disease or the primary prevention of future disease. Much of our current understanding of disease pathogenesis, as discussed in other chapters of this volume, has been derived from basic science investigations of animal models of MS such as experimental autoimmune encephalomyelitis (EAE), and these models have provided considerable insight both to the complexity of the mammalian immune system and to the mechanisms underlying its dysfunction in inflammatory autoimmune conditions. Nevertheless, MS is a disease of humans without any known, naturally occurring, counterpart in any nonhuman species. For this reason, the clues to disease pathogenesis provided by a study of basic epidemiologic facts regarding MS (and by a systematic consideration of their implications) are essential to a comprehensive understanding of the human illness we call MS.

Abstract
Multiple sclerosis (MS) is a common inflammatory demyelinating disorder of the central nervous system. It frequently affects females in their reproductive phase of life. Therefore, family planning, pregnancy, and breastfeeding are important issues in the management of MS, particularly with respect to counseling and drug treatment. This paper reviews currently available data on the outcome of pregnancies in MS patients and the influence of pregnancy on the course of the disease. We give an update on the use of various disease-modifying MS drugs during pregnancy and breastfeeding. In addition to established therapies such as interferon-β, glatiramer acetate, natalizumab, and fingolimod, we also discuss the state of knowledge about new agents such as dimethyl fumarate, teriflunomide, and alemtuzumab in the context of pregnancy and breastfeeding.

Abstract
As multiple sclerosis (MS) typically starts at about 30 years of age, and is twice more frequent in females than in males, women with MS frequently face issues related to pregnancy and to the effects of medications commonly used in MS treatment. In this review, the authors provide and summarize literature data addressing the effect of MS and its treatments on pregnancy, delivery, postpartum and conception. There is a strong evidence that relapses are fewer during pregnancy but more frequent during postpartum, and that IFN-β and glatiramer acetate do not expose patients and their babies to relevant adverse events; nevertheless, these drugs should be discontinued during pregnancy and before conception. However, if their preventive withdrawal exposes patients to a high risk of disease activity, these medications could be continued until proven conception. Little information is available on the effect of natalizumab and fingolimod.

Abstract
Background: Several studies have shown that pregnancy reduces multiple sclerosis (MS) relapses, which increase in the early postpartum period. Postpartum relapse risk has been predicted by pre-pregnancy disease activity in some studies. Objective: To re-examine effect of pregnancy on relapses using the large international MSBase Registry, examining predictors of early postpartum relapse. Methods: An observational case–control study was performed including pregnancies post-MS onset. Annualised relapse rate (ARR) and median Expanded Disability Status Scale (EDSS) scores were compared for the 24 months pre-conception, pregnancy and 24 months postpartum periods. Clustered logistic regression was used to investigate predictors of early postpartum relapses. Results: The study included 893 pregnancies in 674 females with MS. ARR (standard error) pre-pregnancy was 0.32 (0.02), which fell to 0.13 (0.03) in the third trimester and rose to 0.61 (0.06) in the first three months postpartum. Median EDSS remained unchanged. Pre-conception ARR and disease-modifying treatment (DMT) predicted early postpartum relapse in a multivariable model. Conclusion: Results confirm a favourable effect on relapses as pregnancy proceeds, and an early postpartum peak. Pre-conception DMT exposure and low ARR were independently protective against postpartum relapse. This novel finding could provide clinicians with a strategy to minimise postpartum relapse risk in women with MS planning pregnancy.

Abstract
Multiple sclerosis (MS) is the most commonly acquired neurological disorder affecting young adults of reproductive age with approximately a 3:1 female-to-male ratio. Pregnancy is not contraindicated in MS but remains to be an issue that raises many questions. Although relapse rates tend to increase in the first 3 months postpartum, pregnancy does not seem to be a detriment to the long-term progression of MS and has a protective effect on reducing relapses, especially during the third trimester. MS does not appear to affect fertility or increase the risk of congenital anomalies or pregnancy complications. There has been some evidence that maternal treatment with β interferons, the most commonly used disease-modifying therapies in MS, may cause adverse reproductive outcomes, prompting the US FDA to issue warnings about their use at conception and during pregnancy.

Abstract
Multiple sclerosis is the most common chronic autoimmune disease of the central nervous system which preferentially affects females at childbearing age. For this reason, patients and treating physicians were frequently confronted with questions concerning family planning, pregnancy and birth. Preventive and personalized treatment approaches are considered, because topics as heredity, risk of congenital malformations, influence of pregnancy on MS and aspects of drug therapy during the period of conception, pregnancy, puerperium and lactation have to be discussed. Here, we provide an overview about the current state of knowledge regarding these issues.

Abstract
Cellular mechanisms underlying sexual dimorphism in the immune response remain largely unknown. Concerning the interactions among the nervous, endocrine and immune systems, we reported that during gestation, a period during which multiple sclerosis (MS) clearly ameliorates, there is a physiological expansion of regulatory T-lymphocytes (T(Reg)). Given that alterations in T(Reg) proportions and suppressive function are involved in MS pathophysiology, we investigated the in vitro effect of sex hormones on T(Reg). Here, we show that both E2 and progesterone (P2) enhance T(Reg) function in vitro, although only E2 further induces a T(Reg) phenotype in activated responder T-cells (CD4(+)CD25(-)) (P < 0.01). E2 receptor beta (ERβ) percentages and mean fluorescence intensity (MFI) on T(Reg) were lower in MS patients than in controls (P < 0.05), in parallel with lower E2 plasma levels (P < 0.05). Importantly, percentages and MFI of ERβ were higher in T(Reg) than in T-responder cells (P < 0.0001) both in MS patients and controls. We show a unique differential pattern of higher ER and PR levels in T(Reg), which may be relevant for the in vivo responsiveness of these cells to sex hormones and hence to MS physiopathology.

Abstract
Multiple sclerosis (MS) is often diagnosed among women of childbearing age. This article reviews how MS affects pregnancy and provides information for health care providers who care for women with this disorder. Women with MS need to be informed regarding how the disease will affect their reproductive health. The disease itself does not usually have a negative impact on fertility or pregnancy, although some studies indicate that women with MS have a slightly increased risk for having small-for-gestational-age newborns. Some of the common MS symptoms such as fatigue, urinary frequency, constipation, and mood changes are similar to pregnancy-related symptoms. Mode of birth and anesthesia choices are similar to those for women without MS. Immunomodulatory therapy for MS needs to be discontinued before conception because most of the medications are still under investigation with regard to safety during pregnancy or have adverse effects on pregnancy. Relapse rates are increased for up to 6 months in the postpartum period. Breast feeding does not appear to increase the risk of postpartum relapses. All hormonal contraception can be used by women with MS. Some studies suggest that estrogen may have protective effects against disease progression.

Abstract
BACKGROUND Although several papers report on pregnancy and multiple sclerosis (MS), no systematic review of the literature has been carried out. Neurologists and obstetricians need to have proper information to discuss with women presenting with MS who consider pregnancy. OBJECTIVES Literature review and meta-analysis of data on pregnancy in women with MS. SEARCH STRATEGY The present work followed the recommendations of the PRISMA Statement. Using the PICO framework, the authors independently searched for the terms 'pregnancy' OR 'gestation' OR 'pregnant' AND 'multiple sclerosis' OR 'MS' in the following databases: EMBASE/Excerpta Medica, Medline, Pubmed, Scopus, Index Medicus, Biomed Central, Ebsco Fulltext, LILACS, Scielo and the Cochrane Database of Systematic Reviews. SELECTION CRITERIA only papers presenting original work with analysis of at least one of the outcomes among pregnant women with MS were included. DATA COLLECTION AND ANALYSIS Two independent workers performed the literature review. All the authors selected and read the relevant papers. Two other authors summarised data for analysis. MAIN RESULTS Twenty-two papers reporting on 13,144 women with MS and their pregnancies were analysed. A significant decrease in relapse rate was observed during pregnancy, followed by a significant increase after delivery. Miscarriages, low birthweight, prematurity, neonatal death and malformations were assessed among these women and their offspring. There seems to be a regional influence on the rates of caesarean sections and abortions among women with MS. Neonatal death and malformation rates did not seem to be particularly high. AUTHORS' CONCLUSIONS The present work provides evidence-based data that can be discussed with women with MS and their relatives when pregnancy is considered by these families.

Abstract
Although multiple sclerosis (MS) affects both women and men, women are more susceptible to MS than men. Accumulating evidence indicates that the incidence and prevalence of MS is increasing, more so in women than in men. Owing to pregnancy, differing hormonal states and distinct social roles, the impact of MS differs between women and men. Since Patricia K Coyle published a review on gender issues in MS, multiple studies have added to the body of knowledge. This update will summarize the current thinking on gender-related issues in MS and we will address incidence and prevalence, hormonal factors, pregnancy and breastfeeding, genetics, course and prognosis, imaging, treatment and psychosocial aspects. Future progression within this field will help elucidate the cause of and define the treatment of MS.

Abstract
Multiple sclerosis (MS) is a central nervous system chronic inflammatory disease that is characterized by an extensive and complex immune response. Scientific advances have occurred in immunology, pathophysiology, and diagnostic and clinical assessment tools, and recent discovery of unique therapeutic targets has spurred numerous Phase II and Phase III clinical trials. Reductions in MS relapse rates and improvements in T2 or gadolinium-enhancing lesion burdens have been reported from Phase III trials that include fingolimod, alemtuzumab, cladribine, and rituximab. Promising Phase II trial data exist for teriflunomide, daclizumab, laquinimod, and fumarate. The optimism created by these favorable findings must be tempered with evaluation of the adverse effect profile produced by these new agents. Given the discovery of progressive multifocal leukoencephalopathy with the use of natalizumab, ongoing vigilance for rare and life-threatening reactions due to new agents should be paramount. Patients with MS often experience difficulty with ambulation, spasticity, and cognition. Recent clinical trial data from two Phase III dalfampridine-SR trials indicate certain patients receive benefits in ambulation. This article provides an overview of data from clinical trials of newer agents of potential benefit in MS.

Abstract
Background The influence of pregnancy on Multiple Sclerosis (MS) has been extensively studied but such influence on Latin American women with MS has not been characterized. Our objective was to describe the course of pregnancy and birth outcome in Argentinean MS patients and the evolution of MS during pregnancy and after delivery. Method We used a retrospective design in eight MS centers in Argentina and administered a survey to women with definite MS (Mc Donald) with pregnancies during or after MS onset. We contacted 355 women of which 81 met inclusion criteria. We recorded 141 pregnancies. Results Involuntary abortion was observed in 16% of pregnancies (95% CI = 10–23). Thirty five women received immunomodulatory therapy (IMT) before 42 pregnancies. Twenty three (55%) out of 42 pregnancies were exposed to IMT. The mean time of IMT discontinuation before conception in 19 (45.2%) pregnancies without exposure, was 104 days (95% CI = 61.0–147.0). There were 103 deliveries: 79% full term. Birth defects were detected in 19% of pregnancies exposed to IMT (95% CI = 4–46) and in 2% of non-exposed (95% CI = 0.3–8.0). The mean relapse rate was: pre-pregnancy year: 0.22 (95% CI = 0.12–0.32); pregnancy: 0.31 in 1st (95% CI = 0.10–0.52), 0.19 (95% CI = 0.03–0.36) in 2nd, and 0.04 in 3rd trimester (95% CI = –0.04–0.12); 1st trimester post delivery: 0.82 (95% CI = 0.42–1.22). Conclusion We observed a higher rate of birth defects among infants exposed to immunomodulators in utero than those not exposed. The reduction in MS relapses during 2nd and 3rd trimester of pregnancy and its increase during postpartum is consistent with previous reports.

Abstract
Relapses, exacerbations, and attacks are synonymous for new or worsened neurologic symptoms that are the hallmark of relapsing-remitting multiple sclerosis. Management of relapses is not always straightforward. The clinician must distinguish between true relapses, symptom fluctuation, and pseudo-relapses. Risks and benefits of treating a relapse must be considered. Once the decision to treat is made, most clinicians would pursue a course of corticosteroids. Consensus may end there, as there is no clear-cut "best" route of administration or dosing schedule. The patient presenting with their first relapse or clinically isolated syndrome may be at risk for the development of multiple sclerosis. Clinical presentation, CSF findings, and MRI may all give clues as to the risk for future demyelinating events.

Abstract
Pregnancy and family planning issues are prominent concerns in the medical care of multiple sclerosis patients, since the disease onset often coincides with a period of life that is decisive in this regard. Multiple sclerosis is a chronic disorder with an unpredictable course and is widely treated with long-term immunomodulatory agents, raising questions regarding the complications and effects of these therapies on pregnancy. This paper gives an overview of the relevant literature and provides a basis for individual counselling of this group of multiple sclerosis patients.

Abstract
BACKGROUND Previously, multiple sclerosis (MS) has been thought to be associated with changes in hormone levels. This study investigates the association between the age of menarche and the age of onset of the first symptoms of MS. METHODS A complete list of patients diagnosed with MS in the province of Newfoundland and Labrador was constructed. The age of menarche for our entire relapsing remitting female MS (RRMS) population was requested by mailout survey. Age of symptom onset was ascertained by chart review. RESULTS A 74% rate of return on the survey results was obtained (150 RRMS patients). A linear regression model demonstrated that the age of first symptoms increased by 1.16 years as the age of menarche increased by one year (R2 = 0.69, P = 0.04). Another analysis showed that the average age of first symptoms for women with reported menarche from 10 to 12 years was 28.96 years compared with 31.83 years for a reported menarche from 13 to 15 years, a significant difference (P = 0.047, t-test). CONCLUSIONS This study suggests that menarche may be related to the pathogenesis of MS.

Abstract
The influence of pregnancy in multiple sclerosis (MS) has been a matter of controversy for a long time. Women with MS were often discouraged to envisage pregnancy. The Pregnancy in Multiple Sclerosis (PRIMS) study was the first large-scale prospective study aimed at assessing the possible influence of pregnancy and delivery on the clinical course of MS. Two hundred and fifty-four women with a diagnosis of MS were included during pregnancy and followed-up till the end of the second year post partum. The results were a reduction in the relapse rate during pregnancy, in comparison to the year before pregnancy, especially marked in the third trimester, and a significant increase in the relapse rate in the first trimester post partum. From the second trimester post partum on however, the relapse rate did not significantly differ from the pre-pregnancy rate. About one third of the women experienced a post partum relapse. Pregnancy did not influence disability progression. The clinical factors likely to predict a relapse in the three months after delivery were analyzed by logistic regression analysis. Women with a greater disease activity in the year before pregnancy and during pregnancy had a higher risk of relapse in the post partum three months. Neither breast-feeding, nor epidural analgesia correlated with presence of a post partum relapse. When comparing the predicted and observed status however, only 72 percent of the women were correctly classified by the multivariate model. It seems unwise therefore to use this kind of model to select women that would benefit from a putative preventive therapy. The PRIMS study had other major consequences: it fostered the development of specific therapeutic strategies to prevent post partum relapses (IV immunoglobulins, IV methylprednisolone), and suggested a potential role of sexual hormones in the natural history of MS during pregnancy and the post partum, therefore identifying them as a preferential target for prevention. The preventive effect of progesterone combined with estradiol on post partum relapses will be tested in a large-scale randomized and placebo-controlled European trial, the POPART'MUS study.

The preventive effect of progesterone combined with estradiol on post partum relapses is about to be tested in a large randomized and placebo-controlled European trial, the POPART'MUS study.

Abstract
Pregnancy represents a physiological transitory state of immune tolerance to avoid the rejection of the foetus, and concomitantly of stabilisation of many autoimmune diseases, such as multiple sclerosis (MS). Alterations in regulatory T-lymphocytes (T(Reg)) are known to be involved in organ-specific autoimmune disease pathophysiology. Our goal was to quantify CD4+ CD25+ and CD4+ CD25hi+ T(Reg) and activated (CD4+ HLA-DR+ CD38+) T-lymphocytes during pregnancy and puerperium in 13 MS patients in comparison with healthy pregnant and non-pregnant women. During pregnancy, a progressive parallel increase in CD4+ CD25+ T-lymphocytes in healthy pregnants as well as MS pregnant patients was observed. The proportion of T(Reg) was significantly higher in all pregnants than in non-pregnant women (p=0.01), whereas no differences were observed neither in the percentages of total nor activated CD4+ T-lymphocytes. In MS patients, CD4+ CD25+ T-lymphocytes significantly decreased when comparing the third trimester with the puerperal period proportions (p = 0.01), whereas CD4+ CD25hi+ T-lymphocytes significantly increased (p = 0.002). Our findings are consistent with the expansion of circulating regulatory CD4+ CD25+ T-lymphocytes pool with suppressive activity during normal pregnancy and in MS. A different pattern of CD+ CD25hi+ T-lymphocytes between healthy pregnants and MS women, which may represent relevant factors in the activity course of MS.
