Management of women with multiple sclerosis through pregnancy and after childbirth

Maternal and neonatal outcomes in pregnant women with multiple sclerosis disease: A systematic review and meta-analysis

OBJECTIVES

Little is known regarding the impact of multiple sclerosis (MS) on maternal and neonatal outcomes. Consequently, this systematic review and meta-analysis aimed to study the impacts of MS on maternal and neonatal outcomes in pregnant women with a history of MS.

METHODS

This review was designed in line with the PRISMA guidelines. Two researchers conducted independent reviews of the literature without time restrictions until January 2023 using international databases, including PubMed, Web of Science, CINAHL Plus, Embase, Scopus, Science Direct, and Google Scholar. A random-effect meta-analysis, using the db metan command in Stata 17.2, was used to calculate the pooled measure of association.

RESULTS

The meta-analysis identified 15 studies involving 33,174,541 pregnant women (32,191 with MS and 33,142,350 as controls). The findings indicate that women with a history of MS are at an increased risk of cesarean delivery (OR=1.28, 95% Confidence Intervals [CI]: 1.14-1.45, p-value: 0.042). Also, these women are at higher risk of neonatal outcomes, such as preterm birth (OR= 1.39, 95% CI: 1.08-1.78, p-value: 0.02), congenital malformations (OR=1.32, 95%CI: 1.16-1.50, p-value: 0.031), Apgar score <7 (OR=2.13, 95% CI: 1.19-3.79, p-value: 0.03), and small for gestational age (OR=1.27, 95% CI: 1.08-1.51, p-value: 0.040).

CONCLUSION

Pregnant women with MS have a greater chance of adverse pregnancy results than pregnant women without MS. Consequently, pregnant women with MS should create detailed before and after pregnancy plans, in consultation with their doctors, spouses, families, and friends, regarding the necessary care and supplements. Future studies applying a prospective cohort design that control for potential confounders are needed to further validate the findings.

Expert opinion on the use of contraception in people with multiple sclerosis

BACKGROUND

Current guidance on the selection of appropriate contraception for people with multiple sclerosis (PwMS) is lacking.

OBJECTIVE

To address this gap, an expert-led consensus program developed recommendations to support clinicians in discussing family planning and contraception with women and men with multiple sclerosis (MS).

METHODS

A multidisciplinary steering committee (SC) of 13 international clinical experts led the program, supported by an extended faculty of 32 experts representing 18 countries. A modified Delphi methodology was used for decision-making and consensus-building. The SC drafted 15 clinical questions focused on patient-centered care, selection of contraception, and timing of stopping/starting contraception and disease-modifying therapies (DMTs). Statements addressing each question were drafted based on evaluation of published evidence and the experts' clinical experience. Consensus was reached if ⩾75% of respondents agreed (scoring 7-9 on a 9-point scale) with each recommendation.

RESULTS

Consensus was reached on 24 of 25 proposed recommendations, including how and when to discuss contraception, types and safety of contraceptives, and how to evaluate the most appropriate contraceptive options for specific patient groups, including those with significant disability or being treated with DMTs.

CONCLUSION

These expert recommendations provide the first practical, relevant, and comprehensive guidance for clinicians on the selection of contraception in PwMS.

Insights for Healthcare Providers on Shared Decision-Making in Multiple Sclerosis: A Narrative Review

Shared decision-making (SDM) between the patient and their healthcare provider (HCP) in developing treatment plans is increasingly recognized as central to improving treatment adherence and, ultimately, patient outcomes. In multiple sclerosis (MS), SDM is particularly crucial for optimizing treatment in a landscape that has grown more complex with the availability of newer, high-efficacy MS therapies. However, little direct evidence on the effectiveness of SDM is available to guide practice. Multiple factors, including patient age, ethnic background, perceptions, invisible MS symptoms, and psychological comorbidities can influence a patient's willingness and ability to participate in SDM. HCPs need to appreciate these factors and ask the right questions to break down obstacles to SDM. The HCP has a responsibility to help patients feel adequately informed and comfortable in having an active role in their care. This review identifies potential barriers to SDM and provides a strategy for HCPs to overcome these obstacles through patient (and caregiver) discussions to ensure optimal patient satisfaction with treatment and thus the best possible outcomes for their patients.

Personalized Use of Disease-Modifying Therapies in Multiple Sclerosis

Multiple sclerosis is an important neurological disease affecting millions of young patients globally. It is encouraging that more than ten disease-modifying drugs became available for use in the past two decades. These disease-modifying therapies (DMTs) have different levels of efficacy, routes of administration, adverse effect profiles and concerns for pregnancy. Much knowledge and caution are needed for their appropriate use in MS patients who are heterogeneous in clinical features and severity, lesion load on magnetic resonance imaging and response to DMT. We aim for an updated review of the concept of personalization in the use of DMT for relapsing MS patients. Shared decision making with consideration for the preference and expectation of patients who understand the potential efficacy/benefits and risks of DMT is advocated.

[Family planning in men and women with multiple sclerosis. Analysis of the Andalusian Registry (2018-2022)]

INTRODUCTION

The Andalusian Registry of Pregnancies in patients with multiple sclerosis is the largest Spanish registry on multiple sclerosis (MS) and family planning. For the first time, it includes information on the fertility of men with MS. The influence of the use of a disease-modifying treatment (DMT) on the health of the foetus/newborn and the impact of breastfeeding on MS are also analysed.

SUBJECTS AND METHODS

This is a multicentre, prospective and observational study. Recruitment of patients took place between December 2018 and December 2020. Women were followed up for one year after delivery. Altogether 100 women and 16 men were included, with a total of 103 newborn infants.

RESULTS

The annualised relapse rate of the women with MS decreased significantly during pregnancy (from 0.23 to 0.065). A total of 11.2% of patients resorted to assisted reproductive techniques in order to conceive a child. No association was found between the use of a DMT at conception and/or pregnancy and the risk of miscarriage, prematurity or low birth weight. Over half the women with MS (54.2%) chose to breastfeed (26.7% of them while on a DMT).

CONCLUSIONS

MS does not affect the fertility of men. Neither does the use of a DMT at the time of conception affect their fertility or their children's health. Assisted reproductive techniques did not have a negative impact on the course of MS. Breastfeeding is a common practice among women with MS and there is no evidence of positive or negative effects on disease progression.

Family planning and multiple sclerosis: A qualitative study of patient experiences to understand information needs and promote informed decision-making

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.

Assisted Reproductive Techniques in Multiple Sclerosis: Recommendations from an Expert Panel

INTRODUCTION

Multiple sclerosis (MS) is mainly diagnosed in women of reproductive age. However, there is a paucity of guidelines jointly prepared by neurologists and gynaecologists on managing women with MS and the desire for motherhood. Therefore, in this review we propose recommendations for such cases, with an particular focus on those requiring assisted reproductive techniques (ART).

METHODS

A group of seven MS experts (4 neurologists and 3 gynaecologists) came together for three discussion sessions to achieve consensus.

RESULTS

The recommendations reported here focus on the importance of early preconception counselling, the management of disease-modifying therapies before and during ART procedures, important considerations for women with MS regarding ART (intrauterine insemination, in vitro fertilisation and oocyte cryopreservation) and the paramount relevance of multidisciplinary units to manage these patients.

CONCLUSIONS

Early preconception consultations are essential to individualising pregnancy management in women with MS, and an early, well-planned, spontaneous pregnancy should be the aim whenever possible. The management of women with MS and the desire for motherhood by multidisciplinary units is warranted to ensure appropriate guidance through the entire pregnancy.

Expert opinion on the pharmacological management of multiple sclerosis in women of childbearing age in Iraq

Background

Multiple sclerosis (MS) is often diagnosed in women of childbearing age (WCBA), with a mean age of onset of 30 years. Women with MS have long been cautioned to carefully plan their pregnancies and, traditionally, disease-modifying therapies (DMTs) have not been recommended for use in patients engaged in family planning. In 2020, the United States Food and Drug Administration (FDA) approved a label update for interferon beta (IFN ß) by adding new safety data on pregnancy and breastfeeding. Because current management guidelines do not yet reflect the recent label update, a panel of neurology experts from Iraq decided to discuss the potential need for changes in treatment strategies in Iraq.

Methods

A panel of experts consisting of 8 neurologists from Iraq and one international neurology expert from Germany convened to develop an expert opinion that would provide practical guidance for the pharmacological management of WCBA with MS in Iraq. They considered the latest label update and relevant published literature, along with local clinical practice and available resources.

Results

Interferon and Glatiramer acetate have no evidence of harm during pregnancy. IFN β can be continued safely through pregnancy. Switching treatment during pregnancy is generally not recommended. Short-term intravenous methylprednisolone can be used to treat disabling relapses.

Conclusion

Given the complexity of managing MS in pregnant women, it is the opinion of the expert panel that family planning should be discussed early in the disease course, planned pregnancy should be encouraged, and open communication with patient for her treatment decisions is paramount. Patients who are engaged in family planning are no longer discouraged from treatment with some of the currently available DMTs.

Fertility preferences and unmet need for family planning in women with multiple sclerosis

BACKGROUND

Most women with multiple sclerosis (MS) have childbearing potential. Although fertility and pregnancy are not affected by MS, the fertility preferences of women with MS can change due to the risk of complications for the mother and/or adverse pregnancy outcomes resulting from the disease or its treatment.

OBJECTIVES

To describe fertility preferences (FPs) and their associated factors, to estimate the Unmet Need for Family Planning (UNFP), use of contraceptives, and history of exposure to disease-modifying therapies (DMTs) during pregnancy in women with MS.

METHODS

In a cross-sectional observational study, a random sample of women with MS were surveyed with the FP subset of the Demographic and Health Survey of Colombia. Factors associated with FP were evaluated through bivariate and logistic regression analysis. The proportion of pregnancies exposed to DMTs, UNFP, and use of contraceptives was estimated.

RESULTS

Of the 141 women interviewed, 101 women had childbearing potential, of whom 49 did not want to have children, 38 were sterilized, 33 wanted to have more children, 19 were undecided, and 2 stated they were unable to bear children (menopause or hysterectomy). No MS-related variables were associated with the preference to have more children. Age (OR 0.91; 95% CI 0.84-0.98) and the number of children (OR 0.23; 95% CI 0.09-0.58) decreased the likelihood of desire for children. Of 116 sexually active women, 87.06 % (101) were using contraceptives, and among them, four were using fertility awareness methods and withdrawal. The UNFP was estimated at 6.03% and was not significantly different from the general population. Eighty-two pregnancies were identified, of which 48 occurred after diagnosis, and 25 were exposed to DMTs.

CONCLUSION

Fertility preference in women with MS is not associated with clinical variables. A large proportion of women choose not to have children and prefer to use permanent contraceptive methods. Although the frequency of contraceptive use was high, some women have the UNFP and use low-efficacy contraceptive methods, which may result in unplanned pregnancies.

Updated Perspectives on the Challenges of Managing Multiple Sclerosis During Pregnancy

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.

Effect of desire for pregnancy on decisions to escalate treatment in multiple sclerosis care: Differences between MS specialists and non-MS specialists

BACKGROUND

Therapeutic inertia (TI) is a worldwide phenomenon that affects 60 to 90% of neurologists and up to 25% of daily treatment decisions during management of multiple sclerosis (MS) patients. A large volume of MS patients are women of childbearing age, and desire for pregnancy is a complex variable often affecting MS care. The objective of this study was to determine the effect of desire for pregnancy on decisions to escalate treatment during management of MS patients.

METHODS

300 neurologists with expertise in MS from 20 countries were invited to participate in the study. Participants were presented with 12 pairs of simulated MS patient profiles reflective of case scenarios encountered in clinical practice. Participants were asked to select the ideal candidate for treatment escalation from modest to higher-efficacy therapies. Disaggregated discrete choice experiments were used to estimate the weight of factors and attributes affecting physicians' decisions when considering treatment selection. An excel calculator that provides estimates as the percentage of participants that would escalate treatment for a simulated case-scenario was constructed.

RESULTS

229 (76.3%) completed the study. The mean age (SD) of study participants was 44 (±10) years. The mean (SD) number of MS patients seen per month by each neurologist was 18 (±16). Non-MS specialists were significantly less likely to escalate treatment than MS specialists across mild, moderate, and severe patient cases. These differences were accentuated when case scenarios introduced a desire for pregnancy. The findings were consistent when MRI-lesions, severity of symptoms, and number of relapses were included.

CONCLUSIONS

Desire for pregnancy differentially influences decisions to escalate treatment, suggesting knowledge-to-action gaps between MS and non-MS specialists. Our findings indicate the need for educational strategies to overcome these gaps and improve clinical outcomes for MS patients who desire pregnancy.

What Can We Learn from Sex Differences in MS?

Multiple sclerosis (MS) is the major acquired central nervous system disease of young adults. It is a female predominant disease. Multiple aspects of MS are influenced by sex-based differences. This has become an important area of research and study. It teaches us how the impact of sex on a disease can lead to new insights, guidelines, management, and treatments.

Acute neurological conditions during pregnancy and their management: a review

Less vascular resistance, higher vascular permeability and improved cardiac output include anatomical and physiological changes related to pregnancy. These are needed to accommodate an increase in plasma volume and ensure significant organ infusion. Nevertheless, increases in oestrogen levels may lead to an increase in the risk of coagulation and thrombosis. Increased levels of progesterone increase the risk of thrombosis due to vasodilation, vascular stasis and edoema in these situations. The increased resistance in preeclampsia maternal systemic blood arteries can create high blood pressure that can interfere with blood flow in numerous organs (including liver, kidneys, brain and placenta). The risk of issues such as pulmonary edoema, placental abruption, pneumonia of aspiration, renal failure, hepatic failure and stroke in pregnant women is increased by Preeclampsia and eclampsia. Some peripheral neuropathies (carpal tunnel syndrome, peripheral facial palsy) and central neurological conditions (seizure, migraine, stroke, epilepsy) may become more common during pregnancy because of the exacerbation of the pre-existing neurologic condition or the onset of neurological disturbance caused by pregnancy physiological changes (such as headache or vascular disorders). During the three trimesters of pregnancy, neurological disorders are both peripheral and central. Therefore, an early and correct diagnosis is required to improve pregnancy care, treatment and perinatal outcomes. The aims of this paper are to identify, define and manage the most prevalent peripheral and centrally occurring neurological disorders in the pregnancy.

Pregnancy in women with multiple sclerosis in France from 2010 to 2015: Incidence, outcomes, and exposure to disease-modifying therapies

BACKGROUND

Multiple sclerosis (MS) is usually diagnosed between 20-40 years old, when women often plan to have children.

OBJECTIVE

Our objectives were to estimate pregnancy incidence rates in women with multiple sclerosis (MS), and to describe the use of disease-modifying therapies (DMTs) before conception and during pregnancy, and pregnancy outcomes.

METHODS

This retrospective cohort study included all 15- to 49-year-old women with MS in the French national health insurance database over 2010-2015. A pregnancy was exposed if a DMT reimbursement claim occurred during pregnancy or in the 14 preceding days. We used zero-inflated negative binomial (ZINB) regression models to estimate incidence rates and ordinal and multinomial regression models to estimate DMT exposure and pregnancy outcomes.

RESULTS

The pregnancy incidence rate was 4.5 per 100 person-years. The probability of having a DMT-exposed pregnancy increased from 0.22 in 2010 to 0.30 in 2015. The probability of live birth was 0.72 (95% CI = 0.70-0.74) for exposed pregnancies (varied considerably among DMTs), 0.77 (95% CI = 0.76-0.79) without treatment, and 0.81 (95% CI = 0.79-0.83) if treatment was stopped within the previous year.

CONCLUSION

In this population-based study, we showed an increase of exposed pregnancies over time, beta-interferon and glatiramer acetate being the most used DMTs and associated with the highest probabilities of live birth. Interrupted exposed pregnancies may reflect undesired pregnancies or fear of an adverse outcome, while recent DMT stop probably reflects pregnancy planning.

Pregnancy in patients with multiple sclerosis

Multiple sclerosis (MS) is an autoimmune disorder that affects ~2.5 million people globally. Women of reproductive age are highly susceptible to this disease. This study aims to explore the association between MS and pregnancy. Articles related to the topic under investigation were identified; the search terms included "pregnancy", "multiple sclerosis", "MS", and "women". Only articles published between 2010 and 2020 were included in the review. This review shows that researchers have attempted to explore the link between pregnancy and MS, and the results from previous studies indicate that pregnancy reduces the risk of MS relapse. However, evidence suggesting that pregnancy can affect the long-term progression of MS is lacking. The research results also indicate that MS does not increase the risk of maternal and fetal complications. MS remains a serious autoimmune disorder that affects many women worldwide. The data gathered during this review indicate that a significant correlation exists between pregnancy and MS relapse rates. The findings presented in this review can aid in the management of MS during pregnancy. Furthermore, these research results provide vital insights that caregivers can use to monitor patients with MS during pregnancy.

The Impact of Reproductive Issues on Preferences of Women with Relapsing Multiple Sclerosis for Disease-Modifying Treatments

BACKGROUND

Relapsing-remitting multiple sclerosis (RRMS) is an incurable disease characterised by relapses (periods of function loss) followed by full or partial recovery, and potential permanent disability over time. Many disease-modifying treatments (DMTs) exist that help reduce relapses and slow disease progression. Most are contraindicated during conception/pregnancy and some require a discontinuation period before trying to conceive. Although around three-quarters of people with RRMS are women, there is limited knowledge about how reproductive issues impact DMT preference.

OBJECTIVE

The aim of this study was to measure the preferences for DMTs of women with RRMS who are considering pregnancy.

DESIGN

An online discrete choice experiment (DCE).

METHODS

Participants chose between two hypothetical DMTs characterised by a set of attributes, then indicated if they preferred their choice to no treatment. Attributes were identified from interviews and focus groups with people with RRMS and MS professionals, as well as literature reviews, and included the probability of problems with pregnancy, discontinuation of DMTs, and breastfeeding safety. In each DCE task, participants were asked to imagine making decisions in three scenarios: now; when trying to conceive; and when pregnant.

ANALYSIS

Two mixed logit models were estimated, one to assess the statistical significance between scenarios and one in maximum acceptable risk space to allow comparison of the magnitudes of parameters between scenarios.

SAMPLE

Women with RRMS who were considering having a child in the future, recruited from a UK MS patient register.

RESULTS

Sixty respondents completed the survey. Participants preferred no treatment in 12.6% of choices in the 'now' scenario, rising significantly to 37.6% in the 'trying to conceive' scenario and 60.3% in the 'pregnant' scenario (Kruskal-Wallis p < 0.001). This pattern corresponds with results from models that included a no-treatment alternative-specific constant (ASC) capturing differences between taking and not taking a DMT not specified by the attributes. The ASC was lower in the trying to conceive scenario than in the now scenario, and lower still in the pregnant scenario, indicating an intrinsic preference for no treatment. Participants also placed relatively less preference on reducing relapses and avoiding disease progression in the trying to conceive and pregnant scenarios compared with a lower risk of problems with pregnancy. In the trying to conceive scenario, participants' preference for treatments with shorter washout periods increased.

CONCLUSION

Women with RRMS considering having a child prefer DMTs with more favourable reproduction-related attributes, even when not trying to conceive. Reproductive issues also influenced preferences for DMT attributes not directly related to pregnancy, with preferences dependent on the life circumstances in which choices were made. The design of the DCE highlights the benefits of considering the scenario in which participants make choices, as they may change over time.

Multiple Sclerosis in Pregnancy and its Role in Female Fertility: A Systematic Review

Multiple sclerosis (MS) is a neurological disease that typically affects young women of reproductive age. There are still many questions and heterogeneous clinical approaches partly due to the lack of consensus and guidelines. For many years, women with MS have been discouraged from getting pregnant for fears that the disease might negatively affect the fetus or increase their obstetric risk or for claims that the disease might decrease fertility. However, fertility does not seem to be impaired to a larger extent in women with MS. Therefore, all healthcare providers involved in the follow-up of multiple sclerosis patients must be prepared to discuss future fertility, pregnancy, and others matters, in addition to providing them with the best possible counseling. This study presents data based on updated evidence and discusses fertility and pregnancy in patients with MS with respect to the impacts of pregnancy on the risk and prognostic factors tied to MS, and the impact of MS on pregnancy outcomes and fertility treatments administered to females with MS. In conclusion, a clear relationship between infertility and MS has not been established. There seems to exist a link between disease aggressiveness and progression with several processes that might impair fertility. However, MS does not stand as a contraindication to assisted reproductive technology. From the several studies analyzed, it is possible to conclude that pregnancy is possible in women with MS. It is important to discuss and plan the ideal moment to start treatment and managing pregnancy and contraception aiming at better results.

Family planning in Argentinian women with multiple sclerosis: An important yet seldom approached issue

Background

The purpose of this study was to assess family planning (FP) among women with multiple sclerosis (WwMS).

Methods

We invited 604 WwMS to answer a survey focused on FP: a) Temporal relationship between pregnancy and the diagnosis of multiple sclerosis; b) History of FP; c) Childbearing desire; d) Information on family planning. Comparisons between pregnancy and not pregnancy after MS, as well as, planned and unplanned pregnancy were analyzed. Multivariate and univariate analyses were used to assess the impact of independent variables and FP

Result

428 (71.7%) WwMS completed the survey. A 19.1% got pregnant after MS diagnosis and we evaluated FP in the last pregnancy, 56.1% patients had a planned pregnancy. Professional addressing FP (OR = 0.27, 95%-CI 0.08-0.92, p = 0.03) and non-injection drug treatment before pregnancy (OR = 2.88, 95%-CI 1.01-8.21, p = 0.047) were independent predictors of unplanned pregnancy in our multivariate model. Among WwMS ≤ 40 years, 48.7% had future childbearing desire. Young age (p < 0.001), PDDS <3 (p = 0.018), disease duration <5 years (p = 0.02), not childbearing before MS diagnosis (p < 0.001) and neurologist addressing family planning (p = 0.01) were significantly associated with childbearing desire.

Conclusions

This research highlights that pregnancy remains an important concern among WwMS.

Update on treatment in multiple sclerosis

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system. In recent years, many disease-modifying therapies (DMT) have been approved for MS treatment. For this reason, a profound knowledge of the characteristics and indications of the available compounds is required to tailor the therapeutic strategy to the individual patient characteristics. This should include the mechanism of action and pharmacokinetic of the drug, the safety and efficacy profile provided by clinical trials, as well as the understanding of possible side effects. Moreover, the evolving knowledge of the disease is paving the way to new and innovative therapeutic approaches, as well as the development of new biomarkers to monitor the therapeutic response and to guide the clinician's therapeutic choices. In this review we provide a comprehensive overview on currently approved therapies in MS and the emerging evidence-based strategies to adopt for initiating, monitoring, and eventually adapting a therapeutic regimen with DMT.

Rituximab for treatment of refractory multiple sclerosis relapses during pregnancy

Case Summary: While multiple sclerosis (MS) disease activity declines during pregnancy, there are situations where MS relapses in pregnant women do occur. Mild relapses may be managed with close observation, but severe refractory relapses may require more aggressive management. We describe two cases of rituximab used for severe, refractory multiple sclerosis relapses during pregnancy. Rituximab did not appear to complicate either pregnancy and there were no further relapses for either women. Rituximab should not be overlooked in rare refractory cases, such as the rebound relapses sometimes seen following the discontinuation of lymphocyte-sequestering disease-modifying therapies.

Live birth rates, infertility diagnosis, and infertility treatment in women with and without multiple sclerosis: Data from an administrative claims database

BACKGROUND

Real-world data regarding live birth rates (LBRs) and infertility in women with multiple sclerosis (MS) are lacking. This study compared LBRs, infertility diagnoses, and infertility treatments in women with and without MS.

METHODS

Using a retrospective US administrative claims database, patients 18-55 years with MS were matched 1:1 to patients without MS to compare LBRs, infertility diagnoses, and infertility treatments used between cohorts.

RESULTS

Overall LBRs were lower in women with MS (n=96,937) versus women without (n=96,937; 5.0% vs 7.0%; p<0.0001). A greater proportion of women with MS than without had a diagnosis of infertility (8.5% vs 8.1%; p=0.0006). Fewer women with MS than without used any infertility treatment (1.0% vs 1.2%; p=0.0002). Among women with or without MS who received infertility treatments, no significant difference was observed in LBRs with oral (32.2% vs 31.5%; p=0.8536) or injectable (44.0% vs 49.3%; p=0.2603) treatment.

CONCLUSION

Women with MS had a lower LBR, received more infertility diagnoses, and were less likely to receive infertility treatment than women without MS. There was no difference in LBRs following infertility treatment. Claims-data studies provide valuable exploratory analyses that reflect interactions between patients and the healthcare system.

Disease-Modifying Drugs and Family Planning in People with Multiple Sclerosis: A Consensus Narrative Review from the Gulf Region

Most disease-modifying drugs (DMDs) are contraindicated in pregnancy. Management of MS is especially challenging for pregnant patients, as withdrawal of DMDs leave the patient at risk of increased disease activity. We, a group of experts in MS care from countries in the Arab Gulf, present our consensus recommendations on the management of MS in these patients. Where possible, a patient planning pregnancy can be switched to a DMD considered safe in this setting. Interferon β now can be used during pregnancy, where there is a clinical need to maintain treatment, in addition to glatiramer acetate. Natalizumab (usually to 30 weeks' gestation for patients with high disease activity at high risk of relapse and disability progression) may also be continued into pregnancy. Cladribine tablets and alemtuzumab have been hypothesised to act as immune reconstitution therapies (IRTs). These drugs provide a period of prolonged freedom from relapses for many patients, but the patient must be prepared to wait for up to 20 months from initiation of therapy before becoming pregnant. If a patient becomes pregnant while taking fingolimod, and requires continued DMD treatment, a switch to interferon β or natalizumab after a variable washout period may be prescribed, depending on the level of disease activity. Women who wish to breastfeed should be encouraged to do so, and interferon β may also be used during breastfeeding. There is a lack of data regarding the safety of using other DMDs during breastfeeding.

Discontinuation of disease-modifying treatments in multiple sclerosis to plan a pregnancy: A retrospective registry study

BACKGROUND

For safety reasons multiple sclerosis (MS) treatment guidelines recommend stopping or delaying the onset of disease-modifying therapies (DMT) before a planned pregnancy, but disease stability after DMT discontinuation is not well studied. The objective of this study is to describe the course of MS in patients who interrupted DMT before a planned pregnancy.

METHODS

This was a retrospective study using 2008-2016 data from a multicenter register of pregnancies in women with MS. In this paper, we present data from the subgroup of women with relapsing-remitting MS (RRMS) who interrupted DMT to try to conceive. Data from 1 and 3 years before DMT interruption, the period between DMT interruption and conception or resuming DMT, during pregnancy and one year postpartum were analyzed. Annualized relapse rates (ARR), Expanded Disability Status Scale (EDSS) scores, and magnetic resonance imaging (MRI), obstetric, and neonatal data were collected.

RESULTS

Twenty-seven women interrupted DMT (19 β-interferon, 5 glatiramer acetate, 2 natalizumab and 1 fingolimod) to try to conceive. After a mean of 10.6 months 6 women stopped trying to conceive and resumed DMT, while 21 women became pregnant after a mean of 7.0 months. In the overall cohort, in the period from when DMT was discontinued to when pregnancy was confirmed or DMT resumed, the ARR was 1.08, which was significantly higher than the ARR 1 year (0.44; p = 0.01) and 3 years (0.4; p = 0.06) before DMT discontinuation. The mean EDSS score when pregnancy was confirmed or DMT resumed was significantly higher than at DMT discontinuation (1.8 vs 1.36, p = 0.011). In the subgroup of patients who became pregnant, the ARR in the untreated period before pregnancy was 0.98, which was significantly higher than the ARR 1 year (0.38; p = 0.03) and 3 years (0.39; p = 0.0077) before DMT discontinuation. The ARR decreased to 0.51 during pregnancy and then increased to 0.76 during the first postpartum trimester (not significant). One year after delivery, the mean EDSS score (1.86) was significantly higher than at DMT cessation (1.35, p = 0.027) or pregnancy confirmation (1.45, p = 0.026). Patients who suffered relapses following DMT cessation before becoming pregnant had an 11-fold higher risk of relapse during pregnancy (relative risk [RR] = 11.1 [95%CI 1.6, 75], p = 0.002) and a 3-fold higher risk during the postpartum year (RR = 3.0 [95%CI 1.3,6.6], p = 0.007) than those who did not suffer relapses in period between DMT withdrawal and pregnancy.

CONCLUSIONS

In this retrospective registry study, discontinuation of DMT (mostly immunomodulatory drugs), to try to conceive resulted in an increase in MS relapse rates and disability progression.

Pregnancy Outcomes in Patients With Multiple Sclerosis Exposed to Natalizumab-A Retrospective Analysis From the Austrian Multiple Sclerosis Treatment Registry

Objectives: To analyze safety and impact of natalizumab (NTZ) exposure on the disease course, pregnancy, and newborn outcomes of relapsing-remitting multiple sclerosis (RRMS) patients from the Austrian Multiple Sclerosis Treatment Registry (AMSTR).

Materials and Methods: Twelve pregnancies of 11 women with RRMS exposed to treatment with NTZ were identified from the AMSTR. Exposure to NTZ was defined as treatment with NTZ from 8 weeks prior to the start of the last menstrual period and onward. All patients completed a standardized questionnaire regarding pregnancy and newborn outcomes until the postpartum period for up to 12 months.

Results: NTZ was stopped on average 46 days after the last menstrual period. There were 11 live births and one elective termination due to ectopic pregnancy. Mean gestational age of live born individuals was 39.0 weeks [standard deviation (SD) ± 1.1]. Mean birth weight and length were 3,426 g (SD ± 348) and 51.9 cm (SD ± 1.9), respectively. Apgar scores 1 min after birth were normal, with 9.2 points on average. One child displayed hip dysplasia as the only congenital malformation documented in this cohort. Three patients experienced relapses during pregnancy and three patients in the postpartum period, resulting in confirmed Expanded Disability Status Scale (EDSS) progression in four of them.

Conclusion: In this cohort, there was no increased risk concerning pregnancy and newborn outcomes due to NTZ exposure. However, relapses occurring during pregnancy and postpartum period resulted in confirmed disability.

Aggressive multiple sclerosis (2): Treatment

The natural history of multiple sclerosis (MS) is highly heterogeneous. A subgroup of patients has what might be termed aggressive MS. These patients may have frequent, severe relapses with incomplete recovery and are at risk of developing greater and permanent disability at the earlier stages of the disease. Their therapeutic window of opportunity may be narrow, and while it is generally considered that they will benefit from starting early with a highly efficacious treatment, a unified definition of aggressive MS does not exist and data on its treatment are largely lacking. Based on discussions at an international focused workshop sponsored by the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), we review our current knowledge about treatment of individuals with aggressive MS. We analyse the available evidence, identify gaps in knowledge and suggest future research needed to fill those gaps. A companion paper details the difficulties in developing a consensus about what defines aggressive MS.

Consensus recommendations for family planning and pregnancy in multiple sclerosis in argentina

BACKGROUND

Multiple sclerosis (MS) is the most common chronic immune-mediated neurological disorder in young adults, more frequently found in women than in men. Therefore, pregnancy-related issues have become an object of concern for MS professionals and patients. The aim of this work was to review the existing data to develop the first Argentine consensus for family planning and pregnancy in MS patients.

METHODS

A panel of expert neurologists from Argentina engaged in the diagnosis and care of MS patients met both virtually and in person during 2019 to carry out a consensus recommendation for family planning and pregnancy in MS. To achieve consensus, the procedure of the "formal consensus-RAND/UCLA method" was used.

RESULTS

Recommendations were established based on published evidence and expert opinion focusing on pre-pregnancy counseling, pregnancy, and postpartum issues.

CONCLUSION

The recommendations of these consensus guidelines are intended to optimize the management and treatment of MS patients during their reproductive age in Argentina.

Pregnancy and the Postpartum Period in Women With Relapsing-Remitting Multiple Sclerosis Treated With Old and New Disease-Modifying Treatments: A Real-World Multicenter Experience

Introduction: Trends of disease activity during pregnancy, the postpartum period, and until 24 months from the delivery in the era of new drugs for the treatment of relapsing-remitting multiple sclerosis (RRMS) need to be investigated.

Methods: In this cross-sectional Italian multicenter study, women with RRMS were included; the disease-modifying treatment (DMT) at the time of conception included were: interferons, glatiramer acetate, teriflunomide, dimethyl fumarate, fingolimod, and natalizumab. The main outcome of the study was to determine the rate of relapse occurrence during pregnancy and the postpartum period in all women grouped for each DMT. The secondary outcome was to determine the overall disease activity assessed by NEDA 3 (relapse, disability level, and radiological activity) at 24 months from the date of delivery.

Results: Completed data were available for 81 pregnancies (in 74 women). Women on interferons and glatiramer had longer disease duration than women on dimethyl fumarate, fingolimod, and natalizumab (p < 0.05). Overall, we recorded 25 relapses during pregnancy (11 in 11 women) and the postpartum period (14 in 14 women). Natalizumab was the most commonly DMT in women (3) who experienced relapses during pregnancy. IFNs were the most commonly prescribed DMT in women (8) who experienced relapses during the postpartum period. At logistic regression analysis, specific treatment per se was not associated with relapse occurrence. No differences among the DMTs groups were recorded about NEDA 3 status at 24 months of follow-up.

Conclusions: In our population, there was no difference in terms of relapses occurrence, disability status, and the overall disease activity during a follow up of 24 months.

Management of relapsing-remitting multiple sclerosis in Qatar: an expert consensus

Healthcare systems vary greatly between countries. International, evidence-based guidelines for the management of multiple sclerosis (MS) may need to be adapted for use in particular countries. Two years ago, the authors published a comprehensive consensus guideline for the management of MS in Qatar. Since that time, the availability of disease-modifying treatments for relapsing-remitting MS (RRMS), and our understanding of how to apply those treatments, has increased. The authors present an update to our guidance, focussing on the management of relapsing-remitting RRMS. In particular, the authors consider the optimal use of different DMTs in patients presenting with mild, medium or high disease activity.

Pregnancy-related issues in women with multiple sclerosis: an evidence-based review with practical recommendations

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.

Pregnancy and Multiple Sclerosis: An Update on the Disease Modifying Treatment Strategy and a Review of Pregnancy's Impact on Disease Activity

Pregnancy rates are rapidly increasing among women of reproductive age diagnosed with multiple sclerosis (MS). Through pre-conception, pregnancy and post-partum periods, there is a need for disease control management, to decrease chances of MS relapses while avoiding potential risks to the mother and the fetus. However, pregnancy is not always compatible with the available highly effective MS treatments. This narrative review provides the aspects of pregnancy's outcomes and the impact on disease activity, choices of anesthesia and the management of relapses during the pregnancy and breastfeeding period. Available disease modifying treatment is discussed in the article with new data supporting the strategy of continuing natalizumab after conception, as it is related to a decreased risk of MS relapses during the pregnancy and postpartum period.

Neuro-obstetrics: A multidisciplinary approach to care of women with neurologic disease

The term "neuro-obstetrics" refers to a multidisciplinary approach to the care of pregnant women with neurologic comorbidities, both preconceptionally and throughout pregnancy. General preconception care should be offered to all women, including women with neurologic disease. Women with neurologic comorbidities should also be offered specialist preconception care by an obstetrician who consults with a neurologist, anesthesiologist, and if indicated clinical geneticist and/or other specialists. In women with neurologic comorbidities, neurologic sequelae may influence the course of the pregnancy and delivery. Also, pregnancy may influence the severity of the neurologic condition, depending on the type of disease. Physiologic adaptations during pregnancy and altered pharmacokinetics may cause altered blood serum levels of drugs, leading to decreased or increased drug effects. When administering drugs to a woman who wishes to conceive, it is important to consider possible teratogenic effects and possible secretion in breast milk. Tailoring medication regimens should be considered, preferably preconceptionally. In this chapter, we review general principles of neuro-obstetric care, as well as some specific considerations for neurologists, obstetricians, and anesthesiologists caring for pregnant women with common neurologic conditions.

Obstetric and neonatal complications among women with autoimmune disease

BACKGROUND

The impact of autoimmune diseases on pregnancy remains understudied on a population level. Examination of obstetric and neonatal outcomes among women with autoimmune disease and their infants can provide important insights for clinical management.

METHODS

Autoimmune diseases and outcomes were identified using medical records. Cesarean delivery, preterm birth, preeclampsia, small for gestational age (SGA), neonatal intensive care (NICU) admission, neonatal respiratory distress syndrome (RDS), and perinatal mortality risk was assessed. Poisson regression with robust standard errors estimated relative risks (RR) and 95% confidence intervals (95% CI) with adjustment for maternal characteristics and other chronic conditions.

RESULTS

Women with T1DM were at increased risk for nearly all outcomes including RDS (RR: 3.62; 95% CI: 2.84, 4.62), perinatal mortality (RR: 2.35; 95% CI: 1.12, 4.91), cesarean delivery (RR: 2.16; 95% CI: 2.02, 2.32) and preterm birth (RR: 3.52; 95% CI: 3.17, 3.91). Women with SLE also had higher risk for preterm delivery (RR: 2.90; 95% CI: 2.42, 3.48) and RDS (RR:2.99; 95% CI: 1.99, 4.51) as did women with Crohn's (cesarean delivery RR:1.31, 95% CI: 1.08, 1.60; preterm delivery RR: 1.84, 95% CI: 1.37, 2.49. RA increased risk for SGA (RR:1.66; 95% CI: 1.08, 2.55).

CONCLUSION(S)

Despite the heterogeneity in autoimmune diseases, we observed elevated preterm birth risk for most women with autoimmune disease. SLE and T1DM appeared to confer increased risk for a wide range of adverse outcomes.

Management of Demyelinating Disorders in Pregnancy

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.

Social Media Surveillance of Multiple Sclerosis Medications Used During Pregnancy and Breastfeeding: Content Analysis

Background

Multiple sclerosis (MS) is a chronic neurological disease occurring mostly in women of childbearing age. Pregnant women with MS are usually excluded from clinical trials; as users of the internet, however, they are actively engaged in threads and forums on social media. Social media provides the potential to explore real-world patient experiences and concerns about the use of medicinal products during pregnancy and breastfeeding.

Objective

This study aimed to analyze the content of posts concerning pregnancy and use of medicines in online forums; thus, the study aimed to gain a thorough understanding of patients’ experiences with MS medication.

Methods

Using the names of medicinal products as search terms, we collected posts from 21 publicly available pregnancy forums, which were accessed between March 2015 and March 2018. After the identification of relevant posts, we analyzed the content of each post using a content analysis technique and categorized the main topics that users discussed most frequently.

Results

We identified 6 main topics in 70 social media posts. These topics were as follows: (1) expressing personal experiences with MS medication use during the reproductive period (55/70, 80%), (2) seeking and sharing advice about the use of medicines (52/70, 74%), (3) progression of MS during and after pregnancy (35/70, 50%), (4) discussing concerns about MS medications during the reproductive period (35/70, 50%), (5) querying the possibility of breastfeeding while taking MS medications (30/70, 42%), and (6) commenting on communications with physicians (26/70, 37%).

Conclusions

Overall, many pregnant women or women considering pregnancy shared profound uncertainties and specific concerns about taking medicines during the reproductive period. There is a significant need to provide advice and guidance to MS patients concerning the use of medicines in pregnancy and postpartum as well as during breastfeeding. Advice must be tailored to the circumstances of each patient and, of course, to the individual medicine. Information must be provided by a trusted source with relevant expertise and made publicly available.

Practice guideline recommendations summary: Disease-modifying therapies for adults with multiple sclerosis: Report of the Guideline Development, Dissemination, and Implementation Subcommittee of the American Academy of Neurology

OBJECTIVE

To develop recommendations for disease-modifying therapy (DMT) for multiple sclerosis (MS).

METHODS

A multidisciplinary panel developed DMT recommendations, integrating findings from a systematic review; followed an Institute of Medicine-compliant process to ensure transparency and patient engagement; and developed modified Delphi consensus-based recommendations concerning starting, switching, and stopping DMTs pertinent to people with relapsing-remitting MS, secondary progressive MS, primary progressive MS, and clinically isolated syndromes of demyelination. Recommendations were supported by structured rationales, integrating evidence from one or more sources: systematic review, related evidence (evidence not from the systematic review), principles of care, and inference from evidence.

RESULTS

Thirty recommendations were developed: 17 on starting DMTs, including recommendations on who should start them; 10 on switching DMTs if breakthrough disease develops; and 3 on stopping DMTs. Recommendations encompassed patient engagement strategies and individualization of treatment, including adherence monitoring and disease comorbidity assessment. The panel also discussed DMT risks, including counseling about progressive multifocal leukoencephalopathy risk in people with MS using natalizumab, fingolimod, rituximab, ocrelizumab, and dimethyl fumarate; and made suggestions for future research to evaluate relative merits of early treatment with higher potency DMTs vs standard stepped-care protocols, DMT comparative effectiveness, optimal switching strategies, long-term effects of DMT use, definitions of highly active MS, and effects of treatment on patient-specified priority outcomes. This guideline reflects the complexity of decision-making for starting, switching, or stopping MS DMTs. The field of MS treatment is rapidly changing; the Academy of Neurology development process includes planning for future updates.

Use of glatiramer acetate between 2010-2015: effectiveness, safety and reasons to start GA as first or second line treatment in Swiss multiple sclerosis patients

BACKGROUND

Glatiramer acetate (GA) is one of the first therapies approved for multiple sclerosis (MS). We prospectively included and monitored drug-naïve and pre-treated MS patients who had been prescribed GA for 1 year, to investigate reasons for GA prescription, its effectiveness and safety in real life clinical practice.

METHODS

One year, prospective, multicentre, observational study performed between 2010 and 2015 in consecutive MS and clinically isolated syndrome patients starting GA as a first ("naïve") or second ("switcher") line therapy. Primary endpoint was the annualized relapse rate (ARR) over 1 year of GA treatment (from baseline, V1, to 12 months, V2) in naïve and switchers compared to previous 24 months. Secondary endpoints were: EDSS changes between V1 and V2, frequency of adverse events, and reasons for prescribing and discontinuing GA. Baseline demographics and clinical characteristics were retrieved from medical records, and outcome measures were documented at V1 and V2, and in case of clinical worsening.

RESULTS

One hundred ninety-four consecutive patients were monitored over 12 months (N = 64 naïve, N = 130 switchers). Side effect profile (naïve = 36%, switchers = 28%) and comorbidities (naïve = 31%, switchers = 15%) were the most frequent reasons to start GA. The ARR was reduced in both naïve and switchers during V1-2 as compared to the 24 months preceding V1 [naïve: 0.0 (0.0-0.0) vs 0.5 (0.5-1.0, p = 2.9e-10); switchers: 0.0 (0.0-0.0) vs 0.5 (0.0-0.5, p = 0.022)]. EDSS at V2 was significantly reduced only in naïve [(1.5 (1.0-2.5) vs 2.0 (1.5-2.5), p = 0.003)]. Naïve status and EDSS at V1 were negatively associated with EDSS change between V1-V2 in multivariable analysis (regression coefficient = - 0.436, p = 0.008, and regression coefficient = - 0.263, p = 6.18e-05, respectively). No new unexpected AE was reported.

CONCLUSION

In our Swiss cohort, GA was prescribed mainly to naïve or switcher MS patients fearing interferon related side effects, with various comorbidities or considering pregnancy, and showed effectiveness and safety comparable with data of previous GA studies.

Reproductive history of the Danish multiple sclerosis population: A register-based study

Background:

A diagnosis of multiple sclerosis (MS) may impact the choice of parenthood.

Objective:

To investigate the number of live births, abortions and ectopic pregnancies among persons with MS.

Methods:

From the Danish Multiple Sclerosis Registry, we extracted data from all persons diagnosed with MS from 1960 to 1996 and matched each MS person with four reference persons. We used a negative binomial regression model for the live births and Poisson regression model for abortions and ectopic pregnancies. The total fertility rate (TFR) during 1960–2016 and the annual number of live births in the MS population were analysed.

Results:

Persons with MS had fewer children than reference persons. Fewer women with MS had elective abortions after diagnosis (incidence rate ratio (IRR) = 0.88; 95% confidence interval (CI) = 0.78–1.00) than reference persons. There was no difference regarding the number of elective abortions, spontaneous abortions or ectopic pregnancies after onset. The TFR was lower for women with MS than for reference persons, and the number of annual live births by MS persons increased during 1960–2016.

Conclusion:

MS seems to considerably impact reproductive choices, especially after clinical diagnosis, resulting in the MS population having fewer children than the general population.

Management strategies for female patients of reproductive potential with multiple sclerosis: An evidence-based review

Multiple sclerosis (MS) is an inflammatory, demyelinating, neurodegenerative, immune-mediated disease primarily diagnosed in early adulthood. Multiple sclerosis mostly impacts women of reproductive potential, with pregnancy and birth outcomes being major concerns for many patients. While there is ample evidence that the disease itself has no impact on pregnancy, many women living with MS still question their ability to have children, and the impact of childbearing on their disease in the short and long term. Such questions emphasize the importance of proper guidance from healthcare professionals, particularly neurologists. Management considerations are also complicated by the growing list of available treatment options. This review will summarize current evidence and expert opinion around the management of female MS patients of reproductive potential, from family planning to the postpartum period. Current guidelines on the use of disease-modifying therapies throughout pregnancy will be discussed, as well as other general medical recommendations, to minimize MS disease activity in the peripartum period.

Risks and risk management in modern multiple sclerosis immunotherapeutic treatment

In recent years, there has been a paradigm shift in the treatment of multiple sclerosis (MS) owing to the approval of a number of new drugs with very distinct mechanisms of action. All approved disease-modifying drugs primarily work directly on the immune system. However, the identification of an ‘optimal choice’ for individual patients with regard to treatment efficacy, treatment adherence and side-effect profile has become increasingly complex including conceptual as well as practical considerations. Similarly, there are peculiarities and specific requirements with regard to treatment monitoring, especially in relation to immunosuppression, the development of secondary immune-related complications, as well as the existence of drug-specific on- and off-target effects. Both classical immunosuppression and selective immune interventions generate a spectrum of potential therapy-related complications. This article provides a comprehensive overview of available immunotherapeutics for MS and their risks, detailing individual mechanisms of action and side-effect profiles. Furthermore, practical recommendations for patients treated with modern MS immunotherapeutics are provided.

Toward a Shared-Care Model of Relapsing-Remitting Multiple Sclerosis: Role of the Primary Care Practitioner

The objective of this study was to develop a shared-care model to enable primary-care physicians to participate more fully in meeting the complex, multidisciplinary healthcare needs of patients with multiple sclerosis (MS).

DESIGN

The design consisted of development of consensus recommendations and a shared-care algorithm.

PARTICIPANTS

A working group of 11 Canadian neurologists involved in the management of patients with MS were included in this study.

MAIN MESSAGE

The clinical management of patients with multiple sclerosis is increasing in complexity as new disease-modifying therapies (DMTs) become available, and ongoing safety monitoring is required. A shared-care model that includes primary care physicians is needed. Primary care physicians can assist in the early detection of MS of individuals presenting with neurological symptoms. Additional key roles for family physicians are health promotion, symptom management, and safety and relapse monitoring of DMT-treated patients. General principles of health promotion include counseling MS patients on maintaining a healthy lifestyle; performing standard screening measures; and identifying and treating comorbidities. Of particular importance are depression and anxiety, which occur in >20% of MS patients. Standard work-ups and treatments are needed for common MS-related symptoms, such as fatigue, pain, bladder dysfunction, sexual dysfunction, spasticity, and sleep disorders. Ongoing safety monitoring is required for patients receiving specific DMTs. Multiple sclerosis medications are generally contraindicated during pregnancy, and patients should be counseled to practice effective contraception.

CONCLUSIONS

Multiple sclerosis is a complex, disabling illness, which, similar to other chronic diseases, requires ongoing multidisciplinary care to meet the evolving needs of patients throughout the clinical course. Family physicians can play an invaluable role in maintaining general health, managing MS-related symptoms and comorbidities, monitoring for treatment-related adverse effects and MS relapses, and coordinating allied health services to ensure continuity of care to meet the complex and evolving needs of MS patients through the disease course. RÉSUMÉ: Élaborer un modèle de soins partagés dans les cas de sclérose en plaques récurrente-rémittente. Objectif: Élaborer un modèle de soins partagés afin de permettre aux médecins de première ligne de mieux répondre aux besoins complexes et multidisciplinaires de patients atteints de la sclérose en plaques (SP). Conception : Recommandations résultant d'un consensus et élaboration d'un algorithme en matière de soins partagés.

PARTICIPANTS

Un groupe de travail formé de onze neurologues canadiens impliqués dans la prise en charge de patients atteints de la SP. Message-clé : La prise en charge clinique de patients atteints de la SP est de plus en plus complexe dans la mesure où des médicaments modificateurs de l'évolution de la maladie (MMSP) deviennent accessibles et où un suivi permanent en matière de sécurité est nécessaire. Soulignons aussi qu'un modèle de soins partagés incluant les médecins de première ligne est nécessaire. Ces professionnels peuvent permettre un dépistage plus rapide de la SP chez des individus présentant des symptômes neurologiques. Ils peuvent aussi jouer un rôle de premier plan en matière de promotion de la santé, de soulagement des symptômes et de suivi de patients traités avec des MMSP en ce qui a trait à leur sécurité et à de possibles rechutes. Parmi les principes généraux de promotion de la santé, on peut inclure les suivants : offrir aux patients atteints de la SP des conseils leur permettant de maintenir de saines habitudes de vie ; adopter des mesures de dépistage standards ; identifier et traiter les comorbidités. À cet égard, l'anxiété et la dépression sont d'une importance particulière et sont fréquemment signalées (> 20 %) chez les patients atteints de SP. Des démarches d'investigation et des traitements standards sont nécessaires dans le cas des symptômes courants reliés à la SP, par exemple de la fatigue, des douleurs, une dysfonction vésicale, des dysfonctions sexuelles, de la spasticité et des troubles du sommeil. On l'a dit, un suivi permanent s'impose dans le cas de patients bénéficiant d'un traitement spécifique avec des MMSP. Les médicaments associés à la SP sont généralement contre-indiqués durant la grossesse de sorte qu'on devrait conseiller aux patients d'adopter des méthodes de contraception efficaces.

CONCLUSIONS

La SP est une maladie complexe et invalidante qui, à l'instar d'autres maladies chroniques, exige des soins multidisciplinaires continus afin de répondre, en lien avec un tableau clinique précis, aux besoins en constante évolution des patients. Les médecins de première ligne peuvent jouer un rôle irremplaçable à plusieurs égards : dans le maintien d'une bonne santé ; le suivi et le soulagement des symptômes et des comorbidités reliés à la SP ; le suivi des rechutes et des effets indésirables associés aux traitements. N'oublions pas non plus la coordination des services paramédicaux afin d'assurer, durant l'évolution de la SP, une continuité des soins répondant aux besoins complexes et en constante évolution des patients atteints de cette maladie.

Use and safety of disease-modifying therapy in pregnant women with multiple sclerosis

PURPOSE

The purpose of this study is to describe dispensing patterns and comparative safety of disease-modifying therapies (DMTs) during pregnancy in women with multiple sclerosis (MS).

METHODS

We identified pregnancies from the Truven Health Marketscan® Commercial Claims and Encounters Database (2011-2015) and ascertained MS before delivery from inpatient and outpatient claims. We computed the proportion of women with DMT dispensing claims around pregnancy and estimated risk ratios of spontaneous abortion, infections, cesarean section, preterm delivery, poor fetal growth, preeclampsia, and major structural malformations by DMT exposure.

RESULTS

Of 984 058 pregnancies, 1649 were to women with MS. Thirty-five percent of women with MS filled a prescription for a DMT in the 90 days before pregnancy. DMT use declined during pregnancy but increased again after delivery. Glatiramer acetate and interferon beta were most commonly dispensed. Pregnancies with and without early DMT exposure had similar risks of outcomes to one another and to pregnancies in women without MS. Small numbers did not allow evaluation of specific DMTs.

CONCLUSIONS

Approximately one third of commercially insured women with MS in the United States uses DMTs before conception. Neither MS itself nor early pregnancy use of DMTs overall seems to be associated with a substantial risk of adverse pregnancy outcomes.

A Systematic Review of Discrete-Choice Experiments and Conjoint Analysis Studies in People with Multiple Sclerosis

BACKGROUND

Multiple sclerosis (MS) is a chronic disabling, inflammatory, and degenerative disease of the central nervous system that, in most cases, requires long-term disease-modifying treatment (DMT). The drugs used vary in efficacy and adverse effect profiles. Several studies have used attribute-based stated-preference methods, primarily to investigate patient preferences for initiating or escalating DMT.

OBJECTIVES

To conduct a systematic review of attribute-based stated-preference studies in people with MS to identify common methods employed and to assess study quality, with reference to the specific challenges of this disease area.

METHODS

We conducted a systematic search for studies related to attribute-based stated-preference and MS in multiple databases, including Cochrane and MEDLINE. Studies were included if they were published in a peer-reviewed journal, were on the topic of MS, and used a survey methodology that measured stated preferences for attributes of a whole. Analysis was conducted using narrative synthesis and summary statistics. Study quality was judged against the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) conjoint analysis checklist.

RESULTS

We identified 16 relevant articles reporting 17 separate studies, all but one focusing on DMTs. Most studies were discrete-choice experiments. Study quality was generally high, but we recommend the following: (1) that consideration of sample sizes be improved, (2) that survey design choices be justified and documented, (3) that qualitative approaches for attribute and level selection be incorporated to better involve patients, and (4) that reporting of experimental practice be improved. The effects of DMTs on reproduction and the impact of how risk and uncertainty are presented were identified as neglected research topics. The ISPOR conjoint analysis checklist was found to be unsuitable for the assessment of study quality.

CONCLUSION

Attribute-based stated preference is a useful method with which to examine the preferences of people with MS in their choice of DMT. However, further research embracing the methodological recommendations identified, particularly greater use of qualitative methods in attribute development, is needed.

Factors interfering with parenthood decision-making in an Italian sample of people with multiple sclerosis: an exploratory online survey

BACKGROUND

Little is known about the influence of multiple sclerosis (MS) diagnosis on parenthood attitude in people with MS (pwMS).

OBJECTIVE

To investigate the impact of diagnosis, clinical features and external disease-related influences on parenthood decision-making in Italian pwMS.

METHODS

A web-based survey was posted on SMsocialnetwork.com to investigate clinical status, parenthood desire, influences on family planning, pregnancy outcomes, abortions and adoptions of pwMS.

RESULTS

33/395 respondents never wanted to become parent because of MS ("anti-parenthood after diagnosis"). 362 declared to be in favor of parenthood. 51% pwMS having a child by the survey time had already received the MS diagnosis at first childbirth. The frequency of a second child in pwMS after diagnosis was 38% compared to 67% in people without yet MS diagnosis. 16% of pwMS were discouraged to become parent after diagnosis, mainly by medical personnel. In 71% of respondents, diagnosis did not delay the decision to become parent and only 39% were counseled by treating physician to plan pregnancy. Patients' distribution according to the clinical phenotype (exclusively relapsing vs exclusively progressive) showed a higher proportion of progressive patients in the "anti-parenthood after diagnosis" subgroup.

CONCLUSION

MS diagnosis impacted dramatically on the life project of 7% of pwMS that decided not to have children because of the disease and in pro-parenthood pwMS impacted especially on having the second child. Only a minority was counseled to plan pregnancy. A worse disease course driving to a progressive phenotype at survey time might have negatively impacted on parenthood desire.

Factors Involved in Relapse of Multiple Sclerosis

Multiple sclerosis (MS), a chronic autoimmune disorder, affects the central nervous system (CNS). It affects the brain, spinal cord, and optic nerve, leading to problems with vision, balance, muscle control, and other basic bodily functions. MS relapse (MSR) involves an acute inflammatory demyelinating reaction within the CNS. This review focuses on the main factors involved in MSR based on a detailed literature search. Evidence suggests that MSR is influenced by age, sex, pregnancy, serum levels of Vitamin D, interactions between genetic and environmental factors, and infectious diseases. Many of these factors are modifiable and require the attention of patients and health-care providers if favorable outcomes are to be realized. Identification of MSR risk factors can help in the development of therapies that could be used to manage MS and MSR.

The Short and Long-Term Effects of Pregnancy on Multiple Sclerosis and Experimental Autoimmune Encephalomyelitis

The role of pregnancy in multiple sclerosis (MS) is of importance because many patients with MS are young women in the childbearing age who require information to inform their reproductive decisions. Pregnancy is now well-known to be associated with fewer relapses of MS and reduced activity of autoimmune encephalomyelitis (EAE). However, in women with multiple sclerosis, this benefit is not always sufficient to protect against a rebound of disease activity if disease-modulating therapy is ceased for pregnancy. There is concern that use of assisted reproductive therapies can be associated with relapses of MS, but more data are required. It is thought that the beneficial effects of pregnancy are due to the pregnancy-associated changes in the maternal immune system. There is some evidence of this in human studies and studies of EAE. There is also evidence that having been pregnant leads to better long-term outcome of MS. The mechanism for this is not fully understood but it could result from epigenetic changes resulting from pregnancy or parenthood. Further studies of the mechanisms of the beneficial effects of pregnancy could provide information that might be used to produce new therapies.

Understanding treatment decisions from the perspective of people with relapsing remitting multiple Sclerosis: A critical interpretive synthesis

BACKGROUND

Multiple Sclerosis (MS) is a chronic inflammatory demyelinating disorder of the central nervous system that mainly affects young adults. While there is no cure for MS, disease modifying treatments (DMTs) reduce the relapse rate and partial accrual of disability. More effective DMTs may have higher risks including life-threatening infections or secondary autoimmunity. The complexity and novelty of available treatments cause challenges for clinicians when prescribing treatments and for people with MS (PwMS) when deciding what trade-offs they are willing and ready to make.

OBJECTIVE

To explore the experience of people with relapsing remitting MS (PwRRMS) and their perspectives in choosing treatments.

METHODS

Critical interpretive synthesis was employed to review and synthesis the published literature. Eighty-three publications were selected in a multi-step systematic process.

RESULTS

Findings are presented in four interrelated areas: the influence of the clinical evidence-base in decision making; the meaning of DMT efficacy for PwRRMS; the influence of models of decision-making and information acquisition practices in PwRRMS; and the importance of psychosocial dimensions in DMT decision making. Synthesis of the findings revealed that alongside medical and individual reasoning, contextual circumstances play an important role in making treatment decisions.

CONCLUSION

This review identifies and explains the importance of diverse contextual circumstances (clinical, social, psychological) that are important for PwRRMS when making treatment decisions. The findings demonstrate the importance of eliciting, understanding and addressing such contextual factors.

Pregnancy and childbirth in a patient with multiple sclerosis: A case report of successful management

OBJECTIVE

Multiple sclerosis (MS) preferentially affects females of reproductive age, making reproduction an important issue for women with MS. An increased incidence of poor labor progress often results in assisted vaginal delivery or a cesarean section. However, with good pre-pregnancy counseling and management, women with MS can conceive and give birth safely. Here, we present a case of pregnancy with MS, which was carried to term uneventfully and ended with unassisted vaginal delivery.

CASE REPORT

A 36-year-old woman was treated for MS for three years before she conceived. Because of her mild clinical presentation, medication was discontinued when her pregnancy was confirmed. Counseling was completed, and she had a smooth pregnancy course and gave birth vaginally at 38 weeks and two days.

CONCLUSION

Based on this case report, women with mild clinical presentation of MS before pregnancy can conceive and carry successfully to term with no or improved disease presentation.
