Maternal and Perinatal Outcome in Pregnancy Complicated by Intrahepatic Cholestasis

Abstract

Introduction Intrahepatic cholestasis of pregnancy (IHCP) is characterized by pruritus of the hand and sole with abnormal liver function test and bile acid metabolism. IHCP occurs in the second and third trimesters of pregnancy and usually resolves after delivery. The overall prevalence is about 1.2 to 1.5%. This study was conducted to assess the fetomaternal outcome according to maternal serum bile acids levels and its correlation with liver function tests in patients with IHCP. Material and methods This ambispective observational study was conducted in the department of Obstetrics and Gynecology (OBG) for two years at AIIMS Jodhpur, Rajasthan. It included all the pregnant women attending the outpatient department of OBG with the complaint of pruritis in the palm and sole after 28 weeks of pregnancy and diagnosed with intrahepatic cholestasis of pregnancy after investigations. Results Only 152 patients were diagnosed with IHCP out of 4,148 deliveries, with a prevalence of 3.6%. Among these, 140 (92.11%) had mild IHCP, 10 (6.58%) had moderate IHCP and two (1.32%) had severe IHCP. There was a significant difference between the birth weight in mild, moderate and severe IHCP (P-value 0.004). About 12.5% (n=19) of patients had meconium-stained liquor during delivery. Two patients (1.32%) with moderate IHCP had intrauterine fetal death in the third trimester, and 6.58% (n=10) neonates were kept on continuous positive airway pressure. Conclusions IHCP is associated with adverse fetal outcomes like spontaneous or iatrogenic preterm delivery, low birth weight, increase in the rate of lower section cesarean section (LSCS) and intrauterine death of a fetus. A significant correlation found between raised bile acid levels and variables of liver function test, hence cost-effectiveness and feasibility of liver function test (LFT) should be considered for the management of IHCP.
