Abstract

This cross sectional observational study was done in the division of neonatology, department of pediatrics, Bangabandhu Sheikh Mujib Medical University (BSMMU) in the year 2007. The study population was 50 newborns in total who needed evaluation of sepsis on clinical suspicion. The main objective of this study was to assess serum procalcitonin (PCT) as a better diagnostic marker than CReactive Protein (CRP) in neonatal sepsis. The total study populations were classified into 4 groups like highly probable, probable, and possible and no sepsis group according to the clinical and blood parameters. PCT and CRP were assessed and compared by statistical analysis. For the estimation of PCT and CRP, venous blood was drawn and centrifuged and stored at – 20oC in the refrigerator. Later on PCT was measured by rapid semi quantitative immunochromatographic test. Level of CRP was determined by semi quantitative method (latex). All data were analyzed by SPSS version 10 windows. For statistical analysis appropriate tests were done. In all observations sepsis was found to be more common in male newborns and in those who were delivered by caesarean section. In low birth weight and preterm newborns sepsis was more prevalent. Premature rupture of membrane (PROM) was found to be the commonest maternal clinical condition as a risk factor of sepsis. There was positive correlation between serum PCT and CRP and values of serum PCT as well as CRP differed significantly in the different categories of sepsis indicating relation to the severity of sepsis. PCT is a useful, sensitive and independent biomarker of neonatal sepsis. CRP measurement along with PCT measurement may increase the specificity. Though PCT measurement is comparatively expensive but an easy bed side promt convenient procedure for sick neonates in addition to CRP for rapid evaluation of neonatal sepsis rather than waiting for the report of blood culture.
