OBJECTIVE: To examine the prevalence, etiology, risk factors, and outcomes of liver abnormality in pregnancy, in a tertiary medical center, and to study the potential impact of artificial reproduction techniques (ART) on the incidence and the outcome of pregnancy-related liver abnormality.
DESIGN: A retrospective case-control study using an electronic database and patients' files.
SETTING: Tertiary referral center.
PATIENT(S): Women in the third trimester of pregnancy who were hospitalized for delivery.
INTERVENTION(S): None.
MAIN OUTCOME MEASURE(S): Development of significant elevation of alanine aminotransferase (ALT ≥ 100 IU/L). Secondary outcomes included development of maternal and fetal complications.
RESULT(S): The upper limit of normal of ALT was ≥ 1.5 times and it occurred in 440 (1.6%) pregnancies; of those, 228 (0.8%) had ALT ≥ 100 IU/L. The etiology of significant liver test abnormality was idiopathic in 47% of patients. Compared with spontaneous pregnancies (295/23,793), ART was significantly associated with liver test abnormality (145/4, 520). The presence of ALT ≥ 100 IU/L in the third trimester was associated with higher rates of cesarean sections, prematurity, low birthweight, and fetal complications.
CONCLUSION(S): A definite etiology was not determined in about half of pregnancy-associated liver test abnormality. The ART was significantly associated with liver test elevation. Significant liver test abnormality in the third trimester may have an impact on maternal and fetal/neonatal outcomes.
