Preeclampsia is a serious condition that can occur during pregnancy and can pose problems for both the mother and the baby. It occurs in approximately 2-8% of all pregnancies globally and is caused by issues with blood vessels, leading to elevated blood pressure and other related health concerns. Additionally, insufficient nutrition and inflammation within the mother's body may contribute to the development of preeclampsia.

The HALP score serves as a tool to assess various elements within the blood, indicating inflammation or inadequate nutrition. Although it has been utilized in other medical contexts, its application during pregnancy remains limited. The HALP score has been employed to predict the emergence of ailments such as heart disease and cancer. Given that preeclampsia can stem from inflammation and poor nutrition, the potential of the HALP score in predicting the likelihood of preeclampsia during pregnancy is being examined through research.

Preeclampsia is a hypertensive disorder affecting multiple body systems that poses a risk of maternal and fetal morbidity and mortality. The global prevalence of preeclampsia is estimated to be around 2-8% of all pregnancies. The pathophysiology of preeclampsia is complex and involves endothelial dysfunction and vasospasm, resulting in hypertension and end-organ damage. The development of preeclampsia is influenced by various factors, including abnormalities in the placenta, genetic factors, and maternal immune system. In addition, poor maternal nutrition and inflammation have also been identified as potential contributors to the development of preeclampsia.

The HALP score is a composite measure of hemoglobin, albumin, lymphocyte, and platelet parameters that has been suggested as a possible indicator of systemic inflammation and malnutrition. Although the HALP score has not been extensively studied in obstetrics, it has been investigated in various medical fields as a predictor of adverse outcomes such as cardiovascular disease and cancer. Given the significance of inflammation and malnutrition in the development of preeclampsia, it is important to investigate the potential usefulness of the HALP score in predicting this condition.

Due to the limited research on the application of the HALP score in obstetrics and the possible role of inflammation and malnutrition in the pathogenesis of preeclampsia, a retrospective study is being planned to explore the potential utility of the HALP score as a predictor of preeclampsia. By analyzing the relationship between the HALP score and the development of preeclampsia, valuable insights can be obtained regarding the potential involvement of inflammation and malnutrition in the development of this disorder.
