    Evaluation of dyslipidemia in preeclamptic pregnant women and determination of the predictive value of the hemato-lipid profile: A prospective, cross- sectional, case-control study
    (Galenos Yayincilik, 2022) Melekoglu, Rauf; Yasar, Seyma; Celik, Nesibe Zeyveli; Ozdemir, Halis
    Objective: In this study, we examined the serum hematologic and lipid parameters of pregnant women with preeclampsia and an age-and gestational-age matched normotensive control group. We also compared the ratios of hemato-lipid parameters defined as systemic inflammatory markers and determined the predictive value of these values in preeclampsia. Materials and Methods: All patients diagnosed with late-onset preeclampsia or severe preeclampsia between 34 and 40 weeks of gestation at Inonu University Faculty of Medicine between March 2019 and October 2020 were included. Results: A total of 253 pregnant women were included in the study period. When the study groups were compared in terms of hematological and blood lipid profile; while serum lymphocyte, triglyceride, and total cholesterol levels were significantly higher in the preeclampsia group than in the control group (p<0.001, p<0.001, p=0.013, respectively); high-density lipoprotein (HDL)-cholesterol levels were found to be significantly lower (p=0.017). The cut-off value for the monocyte/HDL ratio in predicting severe preeclampsia was 16.65 with 59.0% sensitivity and 85.4% specificity [the area under the receiver operating characteristic 0.756, 95% confidence interval (CI) 0.681-0.821, p<0.001]. Multivariate analysis showed that the monocyte/HDL ratio was independently associated with both preeclampsia and severe preeclampsia [odds ratio (OR): 1.094; 95% CI 1.009-1.185 and OR: 1.731; 95% CI 1.218-2.459, respectively]. Conclusion: This study demonstrated that serum triglyceride and total cholesterol levels were significantly higher and serum HDL-cholesterol levels were significantly lower in pregnant women with late-onset preeclampsia compared to normotensive pregnant women. Additionally, this study revealed that the measurement of monocyte/HDL ratio in the pregnant population could be a useful clinical tool for predicting preeclampsia.

    Evaluation of serum neopterin, periostin, Tenascin-C, tissue inhibitor of metalloproteinase-1 and matrix metalloproteinase-2 levels in obese pregnant women
    (Galenos Publ House, 2022) Melekoglu, Rauf; Unuvar, Songul; Turkmen, Nese Basak; Cetin, Asli; Celik, Nesibe Zeyveli; Yuce, Hande; Yasar, Seyma
    Objective: To investigate the role of extracellular matrix proteins in the molecular mechanism of inflammatory response in obese pregnant women by comparing serum levels of neopterin, periostin, Tenascin-C, tissue inhibitor of metalloproteinase-1, and matrix metalloproteinase-2 between obese and normal weight pregnant women in the third trimester. Materials and Methods: A prospective cross-sectional study was conducted between April 2021 and December 2021. A total of 84 pregnant women were included and three groups were formed with 28 participants in each group. Results: Serum levels of neopterin, periostin, Tenascin-C and tissue inhibitor of metalloproteinase-1 were significantly higher in class II-III obese pregnant women than in class I obese and normal-weight women (p=0.002, p<0.001, p<0.001, and p<0.001, respectively). There was no significant difference in serum matrix metalloproteinase-2 levels between the groups (p=0.769). Receiver operating characteristic curve analysis showed that Tenascin-C and periostin were effective in predicting pre-eclampsia [area under the curve (AUC)=0.82, 95% confidence interval (CI), 0.72-0.90, p<0.001 and AUC=0.71, 95% CI, 0.60-0.80, p=0.007, respectively]. Conclusion: This study demonstrated that class II-III obese pregnant women had significantly higher serum levels of neopterin, periostin, Tenascin-C, and tissue inhibitor of metalloproteinase-1 in the third trimester. These higher serum levels may be associated with the adverse perinatal effects of obesity during pregnancy.
