Little is known about the evolution of autoimmune hepatitis (AIH) during pregnancy. Some authors reported worsening of the liver disease during pregnancy, whereas others reported stable conditions. We present two untreated patients who had remission of the autoimmune hepatitis in the second half of their pregnancies. One of the patients exhibited this phenomenon twice during two consecutive pregnancies. We speculate that the immunosuppressive effect of pregnancy induced remission of the autoimmune hepatitis in our patients.
