Confirmed relapse rate was 0.25 (95% CI 0.17–0.37) relapses per year in the estriol treated group compared to 0.37 (95% CI 0.25–0.53) relapses per year in the placebo group with an adjusted rate ratio of 0.63 (95% CI 0.37–1.05, p = 0.077).

published a randomized, double-blind, placebo controlled phase 2 trial to assess the safety and efficacy of estriol and progesterone in combination to glatiramer acetate versus glatiramer acetate alone using a primary endpoint of annualized confirmed relapse rate at 24 months, and using a significance level of p = 0.01. There was a 26.5% ( p = 0.04) reduction in CUA lesions in the high dose OC group compared to interferon beta alone and a non-significant reduction in the low dose OC group compared to interferon beta alone. combined low-dose and high-dose oral contraceptives with interferon beta and evaluated disease activity via cumulative number of combined unique active (CUA) lesions on magnetic resonance imagining (MRI) at 96 weeks. The anti-inflammatory effects of estradiol in combination with injectable MS therapies have been demonstrated in preliminary studies. evaluated effects of past-, current- or never-OC use in women with new onset relapsing remitting multiple sclerosis (RRMS) or CIS started on a first-line injectable disease-modifying therapy and found that past OC users had a statistically significant lower annualized relapse rate (ARR) compared to never OC users (Relative Risk (RR) = 0.64, p = 0.031) and that current OC users had a non-statistically significant lower ARR compared to never OC users (RR = 0.97, p = 0.91). Additionally, age of MS onset increased with increasing time of OC use prior to MS onset. found the mean age of MS onset was significantly higher in patients with OC use prior to MS onset than those without OC use (26 years old vs. found a statistically significant relationship between history of OC use (OR = 0.492, p = 0.002) and MS risk and in the duration of OC use (OR = 0.881, p = 0.008) and MS risk. Other studies have supported a positive effect. found that OC use was associated with a slightly increased risk of MS/clinically isolated syndrome (CIS) (adjusted odds ratio (OR) = 1.52, 95% CI = 1.21–1.91 p < 0.001), the risk did not change with duration of OC use, suggesting non-causal association. However, retrospective and prospective studies have reported mixed results regarding oral contraceptive (OC) use and MS risk and have reported a positive influence on relapse rates. In experimental autoimmune encephalomyelitis (EAE) models, administration of estriol improved EAE, which correlated with a decrease in the number of CNS inflammatory cells. The reduction in disease activity observed during pregnancy is thought to be related to high levels of estriol, especially in the third trimester. Oral Contraceptives and Multiple Sclerosis (MS) Disease ActivityĮstrogen has known anti-inflammatory properties and has shown to be neuroprotective in preclinical studies. The purpose of this paper is to provide a practical clinical framework to assist physicians in the treatment of women with MS surrounding pregnancy by reviewing the most recent data surrounding pre-conception care, pregnancy and the post-partum phase in MS with the goal of facilitating informed decisions.ģ.2. In the current era, a neurologist can now be faced with concerns relating to pregnancy, including contraception, fertility, relapses during pregnancy and post-partum, and breastfeeding. Because most disease-modifying treatments (DMT) are contraindicated during pregnancy, understanding the risk behind discontinuation and early pregnancy exposure is important. Evidence supporting a reduction of disease activity during pregnancy is likely contributing to the recent observation that more women with MS are considering pregnancy. The disease predominantly affects females and often starts in childbearing age, making this period a particularly important stage for treatment decisions. Multiple sclerosis (MS) is an autoimmune disease of the central nervous system (CNS) characterized by inflammation and demyelination with almost 1 million affected in the US.
