PEROXIREDOXIN 3 WITH TOXIC METALS IN MISSED ABORTION PATIENTS

Abstract

The most vital factors that hostile health human are toxic heavy metals (THMs). Heavy metals are harmful environmental contaminants that can decrease the likelihood of a healthy pregnancy and afterwards impede a healthy birth. Both paternal and maternal toxic metal exposure could influence pregnancy, So the rates of pregnancy failure are constantly rising. The current study's goal is to explore the effect of Pеrоxirеdоxin 3 antioxidant, as well as some toxic metals (TMs) such as arsenic, cadmium and mercury in missed abortion patients and compared with healthy pregnant and non˗pregnant women without a history of abortion in order to evaluate the degree of this effect on this pathological situation. Additionally, it will demonstrate the connection between these biochemical variables and gestational age. Pеrоxirеdоxin 3 (Prx3), Arsenic (As), Cadmium (Cd), and Mercury (Hg) as a (THMs) were estimated in 40 healthy non˗pregnant (HNP) women, 40 healthy prеgnаnts (HP) with no abortion history, and 20 women with missed abortion (MA). All woman participants are of reproductive age, with the maternal gestational age in the HP and MA groups being ≤ 20 weeks. Maternal gestational age was used to categorize MA and HP women into two groups (1 st & 2 nd trimester). Regarding to the findings of recent research, Prx3 levels declined noticeably in MA patients compared to HP and HNP groups, on other hand the difference of toxic metals which represented in this study as: (As, Cd, and Hg) elevated statistically significantly in MA patients compared to HP and HNP groups. Within the first and second trimesters of pregnancy, the difference of Prx3 levels showed statistically significant reduction between the MA and HP groups. A statistical significance elevation was found between the two comparable gestational age of both groups in regard to blood serum (As, Cd, and Hg) levels. Lastly, the impact of gestational period within MA cases was revealed, serum (Cd) and (Hg) showing a significant variation between the first and second trimester of pregnancy, whereas Prx3 and (As) were unaffected by pregnancy advances within the MA group.
