This longitudinal cohort study of 2.6 million pregnancies suggests that patients with a pre-pregnancy history of Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) are at risk of severe maternal morbidity at delivery. In contrast, patients who develop SJS/TEN during pregnancy are not at risk of severe maternal morbidity, but are at risk of preterm birth and cesarean delivery.
Bouadi et al. (Wed,) studied this question.
