[Immunoreactive diseases in pregnancy].

Immunoreactive diseases in pregnancy are not frequent and it is important to guarantee an optimal and interdisciplinary treatment. The herpes gestationis is a pregnancy-specific disease of the skin with unknown origin and a good prognosis for mother and child. The progressional lupus erythematodes visceralis has a high risk for mother and child, but the rheumatoid arthritis shows remissions during pregnancy. The Basedow's disease and the autoimmune thyroiditis are needed a pregnancy-associated therapy to prevent a hyperthyreotic syndrome of newborns. The autoimmune haemolytic anemia and the thrombocytopenia have a high fetal risk although by intensive management. Myasthenia gravis may cause a transient neonatal syndrome.
