Abstract

Objective: To find the relationship between the quantitative C-reactive protein and lactate as septic markers inneonatal sepsis.Study Design: Cross-sectional study.Place and Duration of Study: This study was conducted at the Neonatal Intensive Care Unit of CombinedMilitary Hospital (CMH), Peshawar, Pakistan from March 2024 to August 2024.Methods: Neonates (age 1 day–28 days) diagnosed with sepsis were enrolled. Patients were categorized intotwo groups: Group I (Survivors) and Group II (Non-survivors). Patient's demographic details, blood cultures,serum C-reactive protein, neutrophil counts, plasma Lactate, and outcome in terms of hospital discharge wereassessed and recorded. Data analysis was done using SPSS version 26.Results: Of the total 136 neonates, there were 76 (55.9%) male and 60 (44.1%) female. The overall mean agewas 14.56±7.82 days. Group I had 92 (67.6%) survivors and Group II had 44 (32.4%) non-survivors. The medianvalue of Lactate (millimole/Liter) and C-reactive protein (milligram/deciliter) was 2.3 (IQR 1.4-5.3) and 2.1 (IQR0.15-8.7), respectively. Survivor group (Group-I) had lower Lactate (1.9 millimole/Liter [1.2–9] than the nonsurvivor group (4.5 millimole/Liter [2.15–7.4]), P < 0.05. The prevalence of multiple organ dysfunction wassignificantly higher in Group-II 82 (89.1%) than in Group-I 16 (36.4%). Based on organism causing infectionsamong 136 neonatal sepsis cases, the incidence of Group B Streptococcus, Escherichia coli, Listeriamonocytogenes, Coagulase-Negative Staphylococci, Staphylococcus aureus, Enterococcus species, Klebsiellaspecies, and Pseudomonas aeruginosa was 58 (43%), 32 (24%), 9 (7%), 7 (5%), 4 (3%), 14 (10%), 10 (7%), and 2(1%), respectively.Conclusion: Lactate is superior to C-reactive protein in predicting prognosis and mortality in neonatal sepsis inthe Neonatal intensive care unit. Elevated levels of lactate and C-reactive protein are primarily associated withincreased severity of neonatal sepsis, including the progression to multiple organ dysfunction syndrome(MODS), septic shock, and poor clinical outcomes.
