ABSTRACT
OBJECTIVE: The objective of this study was to compare the levels of cathepsin B and pentraxin 3 in maternal serum of pregnant women with preeclampsia in the second trimester, to ascertain the impact of these levels on maternal and fetal outcomes, and to present a comprehensive analysis of the combined effects of cathepsin B and pentraxin 3 levels.
METHODS: This prospective case-control study was conducted at Bursa Yuksek Ihtisas Training and Research Hospital between 1 January 2022 and 31 December 2022. The study included 78 pregnant women diagnosed with preeclampsia and 78 healthy pregnant women in the second trimester, between the ages of 18 and 45. Once a diagnosis of preeclampsia was established, maternal serum samples were obtained from the pregnant women prior to the initiation of any therapeutic intervention. Once all samples had been collected, the values for cathepsin B and pentraxin 3 were determined using the ELISA method.
RESULTS: The results demonstrated a statistically significant elevation in the levels of pentraxin 3 (p = 0.008) and cathepsin B (p = 0.005) in pregnancies affected by preeclampsia when compared to those deemed healthy. Moreover, pentraxin-3 (p = 0.007) and cathepsin B (p = 0.002) were found to be significantly elevated in severe preeclampsia compared to mild preeclampsia. A comparison of the groups with and without HELLP syndrome revealed no statistically significant difference between the two groups. The ROC analysis revealed that the Cathepsin B 7.04 cut-off value was statistically significantly associated with the prediction of preeclampsia in all cases, with a sensitivity of 78.2% and a specificity of 47.4% (p = 0.005, AUC = 0.631).
CONCLUSION: The levels of CB and PTX3 may be employed as biomarkers to facilitate the early diagnosis of PE during the second trimester. Furthermore, these biomarkers may prove to be promising for the prediction of PE severity.
