Article informationBackground: Neonatal sepsis is regarded as one of the major health problems throughout the world. Neutrophil to Lymphocyte ratio [NLR] ratios as well as Platelet to Lymphocyte ratio [PLR] are simple, low cost and easily calculated biomarkers that may be employed for earlier diagnosing of neonatal sepsis.
Aim of the work:The present study aims for the assessment of the Platelet to Lymphocyte ratio [PLR] as well as the Neutrophil to Lymphocyte ratio [NLR] in full-term neonates with early-onset sepsis [EOS], and its impact on management.
Patients and Methods:The study involved 50 full-term neonates divided into two groups; patients' group included 30 full-term neonates, diagnosed with EOS [positive blood culture] compared with control group which included 20 healthy full-term neonates.
Results:The study showed no significant difference between cases and controls as regards demographic data. Patients with early-onset sepsis showed significant elevation of absolute neutrophil counts, NLR, PLR, C-reactive protein, in comparison with the control group. Positive predictive value [PPV] of NLR was 99%, PLR was 73%.
Conclusion:NLR and PLR are predictive reliable markers in diagnosing and detecting early onset neonatal sepsis. NLR and PLR showed higher specificity results compared to CRP.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
