Abstract
Background: Neonatal sepsis remains a major cause of neonatal morbidity and mortality, particularly in developing countries. Early diagnosis is challenging because of nonspecific clinical manifestations and the limited sensitivity of blood culture, which remains the gold standard diagnostic test. Thrombocytopenia is one of the most common hematological abnormalities observed in neonatal sepsis and may serve as a useful marker for early diagnosis and disease severity. This study was conducted to evaluate platelet counts in culture-proven neonatal sepsis and determine their association with the etiological profile of infecting organisms.
Methods: A prospective observational study was conducted in the Neonatal Intensive Care Unit (NICU) of Mahatma Gandhi Medical College and Hospital, Jaipur. Neonates with clinical suspicion of sepsis underwent blood culture and hematological evaluation. Only culture-positive cases were included in the study. Demographic characteristics, risk factors, clinical features, platelet counts, and microbiological profiles were recorded and analyzed.
Results: Among 1,489 NICU admissions, 440 neonates were clinically suspected of sepsis, of whom 102 (23.18%) had culture-proven sepsis. Early-onset sepsis accounted for the majority of cases (69.61%), and male neonates constituted 63.73% of affected infants. Moderate-to-severe thrombocytopenia was significantly more common among culture-positive neonates than culture-negative neonates (OR = 90.23; 95% CI: 39.9–204.2; p < 0.0001).
Conclusion: Thrombocytopenia is a common hematological abnormality in neonatal sepsis and shows a strong association with culture-proven infection. Moderate-to-severe thrombocytopenia may serve as a useful adjunctive marker for the early diagnosis and prognostic assessment of neonatal sepsis. Although Gram-negative organisms were associated with greater platelet depletion, platelet count alone could not reliably predict the causative pathogen. Routine monitoring of platelet counts may aid in the early identification of high-risk neonates and facilitate timely therapeutic intervention.
