Abstract

The renin–angiotensin–aldosterone system has an indispensable function in the uteroplacental circulation, placental growth, and blood pressure optimization. The angiotensin I converting enzyme (ACE) gene is a critical integrator for electrolyte balance, and water retention, along with inhibiting preeclampsia. The main goal of this pertaining study is to assess the contribution of ACE*(Ins/Del) variant with the susceptibility for preeclampsia with focus on the severity of the disease among gestational hypertensive women. This retrospective study included 225 participants [125 PE gestational women, and 100 normotensive healthy controls] matching with age, and geographical region. PE women classified into 82 early-onset PE women, accompanied with 43 late-onset PE women. Additionally, PE women categorized into 59 mild PE women, together with 66 severe PE women. The genotyping and characterization of ACE*(Ins/Del) variant were applied using the PCR technique. Our findings indicated higher frequency of the ACE*(Del/Del) genotype and ACE*(D allele) with elevated risk of preeclampsia compared to normotensive controls under recessive (OR = 2.09, and p-value = 0.007), and allelic (OR = 1.75, and p-value = 0.012) models. In addition, testing logistic regression revealed that the levels of endothelin-1 and malondialdehyde exposed significant difference for the ACE*(Del/Del) genotype among early-onset and late-onset PE women (p-value = 0.024, and 0.23, respectively). Furthermore, carriers of the ACE*(Del/Del) genotype observed statistically significant with lower sodium concentrations among severe PE women (p-value = 0.034). The ACE*(Del/Del) genotype and ACE*(D allele) were associated with increased risk preeclampsia among gestational women. Furthermore, early-onset PE and late-onset PE were correlated with endothelin-1 and malondialdehyde concentrations among Egyptian women.
