Role of C-reactive protein, erythrocyte sedimentation rate, progesterone and estradiol hormone levels in first trimester threatened abortion

Abstract

Objective: To assess correlation of High sensitivity C-Reactive Protein (Hs-CRP), erythrocyte sedimentation rate (ESR), progesterone and estradiol levels in the first trimester threatened abortion incidence in Dr. Zainoel Abidin Hospital, Banda Aceh. Methods: Case control design used in this study divided threatened abortion into a case group and normal pregnancy into a control group with a total of 20 subjects for each group. This research was conducted in the Emergency Room and Obstetric Ward of Dr. Zainoel Abidin hospital Banda Aceh in 2019. Eta correlation test was conducted to find out the link between variables towards threatened abortion with 95% confidence level followed by the Receiver Operating Curve (ROC) analysis to find out the cut off points. Results: Progesterone levels (14.76 ng/mL), estradiol (427.61 pg/mL), Hs-CRP (2.57 mg/L) and ESR (28.75 mm/hour) case group were lower compared to the control group. Incidence of threatened abortion correlates to progesterone and estradiol with the correlation strength respectively -0.838 and -0.416. Conclusions: Progesterone and estradiol correlate negatively with first-trimester abortion incidence. Evaluation of these two hormones levels is useful for diagnostic purposes and screening of threatened abortion with a cut point of progesterone 23.03 ng/mL and estradiol 468.8 pg/mL.
