Obstetric cholestasis and its impact on the maternal outcome.

Aim: To evaluate the association of GDM and pre-eclampsia in women with obstetric cholestasis.

Materials And Methods: Pregnant women with > 28 weeks gestation attending ANC, OPD and labor room of J.N.M.C.H, AMU, Aligarh UP (India) from 2020 to 2022 were included in the study after taking informed consent and ethical approval from the Institute. Women were divided into 2 groups, i.e. group 1 having 200 women with IHCP and group 2 having 200 healthy pregnant women; both the groups were followed up for the development of GDM and pre-eclampsia.

Results: A statistically significant association was observed between IHCP and development of GDM [26.5% and odds ratio (OR) 1.64] and pre-eclampsia (17% and OR: 1.95) (p < 0.05), an also GDM and pre-eclampsia were found to be significantly associated with the severity of cholestasis (p < 0.05). Thus, on calculating OR, we found higher odds of developing GDM and pre-eclampsia in IHCP group with raised serum bile acid levels, maximum at 60 μmol/L level as compared to 10-40 μmol/L (GDM: OR: 8.647 and pre-eclampsia: OR: 6.303). Induction and cesarean rates were significantly higher in IHCP group (p < 0.05).

Conclusion: Our study concludes significant association of IHCP with GDM and pre-eclampsia as all three shares common pathogenetic pathways and greater risk of development at higher serum bile acid levels.
