Objective:
To evaluate the relationship of neutrophil/lymphocyte ratio (NLR) with proteinuria and blood pressure level in patients with pre-eclampsia and to investigate whether or not NLR has a role in predicting the severity of pre-eclampsia.
Study Design:
The study comprised 30 healthy pregnant females (Group 1), 37 females with mild pre-eclampsia (Group 2) and 40 with severe pre-eclampsia (Group 3). All the study participants were statistically compared in respect of demographic data, proteinuria levels, and blood pressure levels.
Result:
Age, body mass index, and gestational weeks were similar in all the groups. Maternal NLR was determined to be significantly high in the pre-eclamptic patients (Groups 2 and 3) compared to the healthy pregnant patients (Group 1) (p=0.017). NLR was significantly higher in the severe pre-eclampsia group than in the mild pre-eclampsia group (p=0.032). A significant positive correlation was determined in correlation analysis between NLR and proteinuria (p=0.013, r=0.319). There was also a significant and positive correlation between NLR and systolic/diastolic arterial pressure (p=0.007, r=0.285; p=0.044, r=0.213, respectively).
Conclusion:
In conclusion, while NLR was determined as significantly high in patients with pre-eclampsia, to be able to use this in the classification of the severity of pre-eclampsia, there is a need for further studies on a more extensive population.
