Introduction: Neonatal sepsis is an infection in newborns that may be caused by bacteria, fungi, or viruses and has a high death and morbidity rate. The clinical presentation of sepsis may be rather general, making it challenging to make a diagnosis. While blood culture is the most accurate method to diagnose sepsis, it is also time-consuming. Because of this, it is crucial to locate other biomarkers like C-reactive protein (CRP), high sensitive C-reactive protein (hs-CRP), and procalcitonin (PCT) that may aid in early identification. Aim: To learn about the bacterial composition of suspected cases of neonatal sepsis in a tertiary care hospital in western Uttar Pradesh and how that composition relates to the biomarkers CRP, hs-CRP, and PCT. Materials and Methods: Hundred people who fulfilled the study’s inclusion criteria were included. All neonatal venous blood samples have been obtained after receiving written informed permission from either parent. The conventional method was used to perform the blood culture. The ELISA technique has been used to determine hs-CRP along with serum PCT levels, while the latex agglutination test was utilized for CRP detection. Result: A total of 100 cases were enrolled, 78% presented within 3 days of birth. Blood culture was positive in 33 neonates (33%). There were 17 Gram-positive, 15 Gram-negative, and in all 2 cases with poly bacterial culture. CRP positivity rate was significantly higher in culture positive (57.6%) as compared to culture-negative neonates (25.4%). It was shown that a CRP >6 mg/l level was sensitive at 57.6% and specific at 74.6%. hs-CRP has a 100% sensitivity and 47.8% specificity. The PCT’s sensitivity was 69.7%, whereas its specificity was 89.6%. Conclusion: PCT is more specific for detecting sepsis, but hs-CRP is more sensitive than CRP. The combination of PCT along with hs-CRP has a negative predictive value and high sensitivity compared to other markers. Thus, the most accurate predictors of neonatal sepsis would be a combination of factors. [ABSTRACT FROM AUTHOR]
