Abstract
INTRODUCTION
In multiple sclerosis (MS), foetal exposure to disease-modifying drugs (DMDs) carries varying degrees of risk. We sought to analyse the clinical and obstetric outcomes of MS patients (MSp) exposed to DMDs during pregnancy.
PATIENTS AND METHODS
Observational study. We analysed the clinical-obstetric data of a cohort MSp, who became pregnant between 2007-2017. They were prospectively followed up during pregnancy and postpartum.
CONTROL GROUP
healthy pregnant women (HPW) and MSp unexposed to DMDs.
RESULTS
Sixty-eight pregnancies in MSp. Fifty-six HPW. Thirteen MSp were exposed to DMDs during pregnancy. Obstetric outcome: 2 (15%) infants had low birth weight, no preterm deliveries. Fifty-five MSp were not exposed to DMDs: 22 (40%) discontinued DMD before pregnancy, 33(60%) naïve. Five infants (9%) had low birth weight and 7 (12%) were preterm. HPW: 56. Low birth weight 6 (11%), preterm delivery 6 (11%). There were no differences in relapse incidence during pregnancy-puerperium between MSp groups. There were no differences in birth weight, gestation time, delivery-caesarean section. We found no special obstetric morbidity in women exposed to DMDs.
CONCLUSIONS
There were no significant differences in the clinical and obstetric variables analysed between pregnant women exposed to DMDs, unexposed, and HPW.
