How does inflammatory myositis affect fertility and pregnancy?
There is limited data about pregnancy in these patients. Active disease, especially in early pregnancy, is associated with adverse outcomes. Patients with new onset of poly/dermatomyositis during pregnancy have a high risk of fetal loss. The most common complications are preterm delivery and infants born small for gestational age. Clinical improvement frequently occurs during pregnancy, but postpartum relapse is common. There is no evidence that pregnancy is a trigger for myositis.
