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

Multiple sclerosis (MS) is the most commonly acquired neurological disorder affecting young adults of reproductive age with an approximately 3:1 female to male ratio. Although pregnancy is not contraindicated in MS, data are limited regarding pregnancy outcome among MS patients, and the safety or risk to the fetus associated with most maternal MS treatments, such as disease modifying therapies (DMTs), during pregnancy is unknown. We review available epidemiological and registry data on MS and pregnancy and discuss the need to initiate a North American Multiple Sclerosis Pregnancy Registry that will prospectively identify pregnancies in women with MS, obtain information on the disease, and its treatment during gestation and lactation and follow the children to determine their health status.

Abstract

Multiple sclerosis (MS) is a lifelong disease typically affecting individuals in young to middle adulthood. There are recognized sex differences in MS onset and clinical course. MS affects approximately three times more women than men, thus resulting in less attention to the male experience (i.e. diagnosis, management, societal dimensions). Here, we review current scientific evidence on sex differences in MS risk and course, highlight potential sources of bias, and suggest avenues of further inquiry. We then describe what is known about male experiences with MS diagnosis, treatment, and symptom management (particularly mood and sexual function). Finally, we consider ways in which healthcare providers might engage male patients in the broader aspects of living with MS (e.g. familial and societal relationships) to influence their long-term quality of life (QOL). When possible, we draw from published sources to underscore our collective clinical and scientific experiences.
