Little is known about the evolution of autoimmune hepatitis (AIH) during pr
egnancy. Some authors reported worsening of che liver disease during pregna
ncy, whereas others reported stable conditions. We present two untreated pa
tients who had remission of the autoimmune hepatitis in the second half of
their pregnancies. One of the patients exhibited this phenomenon twice duri
ng two consecutive pregnancies. We speculate that the immunosuppressive eff
ect of pregnancy induced remission of the autoimmune hepatitis in our patie
nts.
