Pregnancy in women with primary biliary cirrhosis

Background & Aims: Primary biliary cirrhosis (PBC) may present in all decades of life, also in childbearing age. Data on maternal and fetal outcome is limited. We aimed to investigate the impact of pregnancy and childbirth on the disease course and possible effects of PBC on fetal outcome. Methods: Retrospective study of local cases and a compact review of published reports between 1950 and 2014. Results: Our cases along with literature review provided 98 pregnancies in 72 PBC patients. PBC was diagnosed during pregnancy in 26 (36%) patients and 46 (64%) had the diagnosis before conception. Twenty-four (30%) of the pregnancies were associated with biochemical flares and 55 (70%) with clinical improvement or stabilization. De nova onset or worsening of pruritus was seen in 49% (45/92). No maternal deaths were reported. Post-partum disease activation was observed in 60% (53/88). One patient was referred for liver transplantation after delivery. A miscarriage rate of 24% and three stillbirths were reported. Most patients were treated with ursodeoxycholic acid (UDCA) during breastfeeding and 12 patients also received UDCA during the first trimester without any identified side effects. Conclusion: Most women with PBC maintain a stable disease during pregnancy, but post-partum biochemical flares are common. Symptomatic pruritus may be challenging in pregnant PBC patients. UDCA appears to be safe during pregnancy and breastfeeding. A successful pregnancy outcome is a realistic expectation for women with PBC. (c) 2014 Elsevier B.V. All rights reserved.
