Study of procalcitonin in neonatal sepsis with blood culture in suspected sepsis in North India
Background: Sepsis can occasionally be difficult to demonstrate, and its difference from non-infectious conditions in critically ill patients is often a challenge. Serum procalcitonin (PCT) assay is one of the biomarkers of sepsis. The aim of the study was to investigate the value of procalcitonin, in the early diagnosis of neonatal sepsis.Methods: A cross-sectional study was conducted at tertiary care hospital in New Delhi. It included all neonates with clinical signs of sepsis. The neonates were divided into two groups as sepsis, and healthy neonates. The PCT level was measured by using ELISA technique and compared between the two groups. Statistical analysis was performed using SPSS windows version 20.0 software.Results: In this study total number of patients included 350, out of which 175 were clinically suspected sepsis cases and 175 were healthy controls. 68 (39%) neonates were show positive blood culture and 107 (61%) neonates were representing negative blood culture report in study group. The mean serum value of PCT was significantly (p<0.001) higher in sepsis neonates. The serum PCT value was significantly increased in neonate’s sepsis with positive blood culture (p<0.001) and negative blood culture (p<0.001) as compared to healthy neonates.Conclusions: It is concluded from this study that the PCT assay was established to be a valuable biomarker of sepsis in this study. The assay might be performed and reported quickly and gave precious information before availability of culture results. This might assist in avoiding unnecessary antibiotic therapy.
