Introduction:

The pathophysiology of preeclampsia is not completely elucidated. Different platelet indices, including the platelet distribution width (PDW), could be used to predict the severity of this condition.

Objective:

To analyze the behavior of PDW in the severity development of preeclampsia in women treated in the maternal-fetal medicine unit of Hospital Simón Bolívar in Bogotá, Colombia.

Materials and methods:

This is an analytical cross-sectional study in 105 patients with hypertensive disorder associated with pregnancy, preeclampsia and severe preeclampsia. We analyzed the behavior of PDW in a population of hypertensive women with preeclampsia using a curve of analysis '' Receiver Operating Characteristic '' (ROC) to estimate the sensitivity, false positive rate, positive and negative likelihood ratio of the test as a marker of development of severity

Results:

PDW had a higher significant increase in patients where their disease progression developed severity characteristics. In the ROC curve, the area under the curve for PDW as a predictor of severity in preeclampsia was 0.68.

Conclusion:

PDW is a platelet index that increased significantly in women with preeclampsia with severity characteristics. PDW could be a marker for the prediction of severity of preeclampsia.
