-Therapy with ursodeoxycholic acid in primary biliary cirrhosis in pregnancy-.

Pregnancy is very uncommon in patients with primary biliary cirrhosis (PBC) and only few reports exist about pregnancy and PBC. However, no data are available on therapy and potential risks of treatment with ursodeoxycholic acid (UDCA) in PBC, especially in the first trimester of pregnancy. Furthermore, it is not known, whether UDCA is secreted into the breast milk during lactation. We report a 41 year old patient with the diagnosis of PBC stage III, who had been treated with UDCA (750 mg/day) for three years. At the time of diagnosis of pregnancy (5th gestational week), UDCA was withdrawn. Within nine days, severe pruritus developed, alkaline phosphatase and gamma-glutamyltransferase increased. UDCA was administered again (750 mg/day). The pruritus disappeared completely within one week. Liver enzymes decreased to baseline values and remained stable throughout the remainder of the pregnancy. No drug-related side effects were observed. Caesarean section for placental insufficiency unrelated to PBC was performed at the 34th week of pregnancy. The newborn thrived normally during a follow-up period of six months. When the patient's breast milk was analyzed by high pressure liquid chromatography, cholic acid, deoxycholic acid and lithocholic acid, but not UDCA were detected in trace amounts. It is concluded that UDCA therapy in PBC may be continued in the early pregnancy and during the breast feeding period. UDCA may be effective for the prevention of cholestasis in PBC during pregnancy.
