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.

To probe the glutathione peroxidase (GPx) activity coupled to ROS and TNF-α levels in younger versus elderly primigravidas. Monocytes were isolated from blood of young and elderly primigravidas after 12 hrs, 24 hrs and 14 days postpartum. Age-matched healthy female donors served as controls. Thereafter, the above monocytes were subjected to evaluation of GPx activity, levels of pro-inflammatory cytokine TNF-α and reactivity/specificity towards anti-TNF-α antibody. Suppression in GPx activity with simultaneous enhancement of TNF-α levels in monocytes was observed after 12 hrs and 24 hrs of spontaneous labor pain-induced maternal delivery through normal vaginal route. Conversely, an enhancement of GPx activity and decrease in TNF-α levels were observed on day 14 of postpartum, thereby indicating reversal of the impaired neutralizing mechanisms. The antioxidant network combating ROS was stronger in younger primigravidas. Capability of TNF-α and ROS suppression was somewhat lesser in elderly primigravidas even 14 days of postpartum via normal vaginal route. The capability of GPx activity enhancement with simultaneous suppression in ROS and TNF-α, decreases in elderly primigravidas. This may act as one of the important parameters leading to a variety of complications encountered by elderly primigravidas. [ABSTRACT FROM AUTHOR]
