Autoimmune inflammatory myopathy in pregnancy.

Autoimmune diseases such as systemic sclerosis, Wegner's granulomatosis, and polyarteritis nodosa are rarely seen in pregnancy, unlike systemic lupus erythematosus, whose association with pregnancy is well studied. Dermatomyositis is a protean disease that affects women in reproductive age. There are only a few case reports documenting the outcome of pregnancy in patients with dermatomyositis/polymyositis. The disease is usually considered to have an adverse effect on pregnancy. Fetal prognosis is guided by the severity of maternal disease and is usually good when the disease remains inactive during pregnancy.
