Insights
Platelet distribution width (PDW) and platelet-large cell ratio (P-LCR) can help predict preeclampsia in early pregnancy. These platelet parameters show potential for early detection of this serious pregnancy complication.
Area of Science:
- Obstetrics and Gynecology
- Hematology
- Maternal-Fetal Medicine
Background:
- Preeclampsia is a significant pregnancy complication impacting maternal and fetal health.
- Platelet parameters are associated with preeclampsia severity.
- Early detection of preeclampsia is crucial for timely intervention.
Purpose of the Study:
- To evaluate the diagnostic potential of platelet parameters in the early second trimester for preeclampsia detection.
- To identify specific platelet indices that can serve as early biomarkers for preeclampsia.
Main Methods:
- Analysis of platelet parameters and clinical data from 840 pregnant women (327 healthy, 209 mild preeclampsia, 304 severe preeclampsia).
- Comparison of platelet parameters across healthy and preeclampsia groups.
- Logistic regression and ROC curve analysis to determine predictive value of platelet parameters for preeclampsia.
Main Results:
- Platelet count did not significantly differ between healthy and preeclampsia groups.
- Mean platelet volume, platelet distribution width (PDW), and platelet-large cell ratio (P-LCR) were significantly elevated in preeclampsia groups.
- Adjusted analysis confirmed PDW and P-LCR as effective predictors of preeclampsia.
Conclusions:
- Platelet distribution width (PDW) and platelet-large cell ratio (P-LCR) demonstrate significant predictive value for preeclampsia.
- These platelet parameters hold potential for clinical application in early preeclampsia screening.
Objective:
Preeclampsia is a serious pregnancy complication that jeopardizes the health of both the mother and the fetus. Platelet parameters are closely linked to the severity of preeclampsia. This study aimed to assess the diagnostic potential of platelet parameters in the early second trimester for the detection of preeclampsia.
Methods:
A total of 840 participants from the Affiliated Hospital of Jining Medical College were included in the study, consisting of 327 healthy pregnant women, 209 with mild preeclampsia, and 304 with severe preeclampsia. General clinical data and platelet parameters for these three groups of pregnant women were collected, and differences among them were compared. In addition, univariate analysis and logistic regression were used to identify preeclampsia risk factors, and receiver operating characteristic curve analysis was conducted to assess the predictive value of platelet parameters.
Results:
Platelet count was not found to significantly differ between the healthy and preeclampsia groups. However, mean platelet volume, platelet distribution width (PDW), and platelet-large cell ratios (P-LCR) were observed to be significantly higher in the preeclampsia group than the healthy group. After adjusting for confounding factors (such as age, gestational week at blood sampling, systolic and diastolic blood pressure, and body mass index during the second trimester), it was determined that PDW and P-LCR could be considered effective predictors of preeclampsia.
Conclusion:
In clinical practice, P-LCR and PDW hold potential predictive value for preeclampsia.

As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
