Aims: Red cell distribution width to platelet ratio (RPR) has been reported as a useful inflammatory marker and prognostic indicator of adult inflammatory diseases. In the present study, red cell distribution width (RDW) and RPR parameters, which are parts of a complete blood count analysis, were compared to the traditional C reactive protein (CRP) and procalcitonin (PCT) parameters to investigate the potential to predict early onset sepsis (EOS) in neonates with or without positive blood cultures. Methods: An observational, retrospective cohort study was conducted to evaluate newborns born in our hospital. Results: RDW, RPR, CRP, PCT, Immature to total neutrophil ratio (I/T), and white blood cell (WBC) counts were higher in suspected and proven EOS compared to control group. Conclusion: We believe that RPR may be used in diagnosis of early onset neonatal sepsis and may be a good alternative to other tools as a readily available biomarker.

D000071074 Neonatal Sepsis Blood infection that occurs in an infant younger than 90 days old. Early-onset sepsis is seen in the first week of life and most often appears within 24 hours of birth.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D015415 Biomarkers Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, ENVIRONMENTAL EXPOSURE and its effects, disease diagnosis; METABOLIC PROCESSES; SUBSTANCE ABUSE; PREGNANCY; cell line development; EPIDEMIOLOGIC STUDIES; etc. Biochemical Markers,Biological Markers,Biomarker,Clinical Markers,Immunologic Markers,Laboratory Markers,Markers, Biochemical,Markers, Biological,Markers, Clinical,Markers, Immunologic,Markers, Laboratory,Markers, Serum,Markers, Surrogate,Markers, Viral,Serum Markers,Surrogate Markers,Viral Markers,Biochemical Marker,Biologic Marker,Biologic Markers,Clinical Marker,Immune Marker,Immune Markers,Immunologic Marker,Laboratory Marker,Marker, Biochemical,Marker, Biological,Marker, Clinical,Marker, Immunologic,Marker, Laboratory,Marker, Serum,Marker, Surrogate,Serum Marker,Surrogate End Point,Surrogate End Points,Surrogate Endpoint,Surrogate Endpoints,Surrogate Marker,Viral Marker,Biological Marker,End Point, Surrogate,End Points, Surrogate,Endpoint, Surrogate,Endpoints, Surrogate,Marker, Biologic,Marker, Immune,Marker, Viral,Markers, Biologic,Markers, Immune
D018805 Sepsis Systemic inflammatory response syndrome with a proven or suspected infectious etiology. When sepsis is associated with organ dysfunction distant from the site of infection, it is called severe sepsis. When sepsis is accompanied by HYPOTENSION despite adequate fluid infusion, it is called SEPTIC SHOCK.
