Investigating protein C and S levels in pregnant women with recurrent early pregnancy loss normal pregnancy.

Miscarriage in the first and second trimesters of pregnancy is very common, and coagulopathy can be a contributing factor. Protein C and S deficiency are rare, inherited disorders that can increase the risk of thrombophilia. Women with these deficiencies have a higher risk of developing blood clots in the placenta, which can lead to placental insufficiency and, ultimately, to a miscarriage. We aimed to compare the levels of protein C and protein S in pregnant females with recurrent first and second-trimester pregnancy loss and normal pregnant females. We performed a detailed history, examination, and various lab tests on a cohort of 40 females with a history of recurrent first and second-trimester abortions visiting an outpatient clinic at a multi-specialty hospital in Kashmir, India. All the findings were compared with 40 women with normal pregnancies. 10% of the participants had low protein C and S levels (P=0.277), out of whom 75% (p<0.001) had intrauterine growth retardation (IUGR) on ultrasound with 67% (p<0.001) having reduced doppler flow in the umbilical artery. 0.05% of participants had isolated protein S deficiency with no concomitant IUGR seen. Patients with protein C and S deficiencies were treated with heparin and progesterone and followed up for pregnancy outcomes. Screening for protein C and S deficiency is mandatory in all cases of recurrent pregnancy loss. Treatment with low molecular weight heparin and progesterone should be initiated to ensure good fetal outcomes and prevent post-partum/postoperative catastrophic venous thromboembolism events.
