Pregnancy and Multiple Sclerosis: Essential Facts to Consider

Pregnancy and Multiple Sclerosis: Essential Facts to Consider

Multiple Sclerosis (MS) is a common neurological disorder that affects approximately 100,000 people in the UK [2]. For those with MS who are considering pregnancy, understanding the potential implications and management strategies is crucial.

Most disease-modifying therapies (DMTs) for MS are classified as class C drugs by the FDA, indicating a potential risk to the developing fetus [1]. However, recent studies suggest that pregnancy might not significantly increase the risk of adverse outcomes for babies born to people with MS [1][3].

During pregnancy, MS symptoms often improve, with a decrease in flare-ups, especially during the third trimester [4]. This improvement may be due to changes in sex hormones during pregnancy [5]. However, the management of MS during pregnancy is complex, as stopping certain treatments, such as natalizumab and fingolimod, is associated with an increased relapse risk during pregnancy [3][5].

Anti-CD20 therapies before conception seem to provide effective relapse control [3]. Some DMTs, such as interferon β and glatiramer acetate, are considered safe during pregnancy [1]. Natalizumab can be used during pregnancy but may cause reversible hematological changes in the newborn if exposure continues into the third trimester [3]. Resuming DMTs shortly after delivery is common and compatible with breastfeeding [1].

Pregnancy may present additional challenges for people with MS. For instance, MS-related damage to the pelvic muscles and nerves might make it more difficult to push the baby out, increasing the risk of assisted deliveries or cesarean sections (C-sections) [1].

Managing MS before getting pregnant may increase a person's chances for an uncomplicated pregnancy [6]. It is essential for people with MS to consider consulting with an MS specialist before getting pregnant [7]. Working with an obstetrician or midwife who has experience with MS and who is willing to support the pregnant person's desires for the birth is also advisable [8].

While pregnancy reduces excessive activation of the immune system in most people with MS, stopping certain MS drugs during pregnancy may make symptoms worse and increase the risk of severe relapses [9]. It is crucial to strike a balance between minimizing relapse risk and ensuring fetal safety [10].

Research suggests that pregnancy might slow the progression of MS and result in lower rates of long-term disability [11]. However, more research is needed to confirm whether MS increases the risk of C-sections, stalled labor, or assisted vaginal delivery [12].

Rates of artificial insemination are higher among people with MS due to difficulties with sexual intercourse [13]. It is generally safe to get pregnant with MS, and people with MS typically have healthy babies [14].

Chemicals associated with breastfeeding may also promote MS symptoms [15]. Therefore, individualised clinical decisions remain important, and ongoing consultations with a specialist can help manage symptoms and make medication decisions [16].

In summary, while pregnancy and MS present unique challenges, careful planning, and consultation with specialists can help ensure a healthy pregnancy and delivery for both mother and baby.
