Coagulase negative staphylococcal septicemia in newborns

Area of Science:

• Neonatal Intensive Care
• Infectious Diseases
• Pediatric Medicine

Background:

• Coagulase-negative staphylococci (C-NS) are a significant cause of healthcare-associated infections in neonates.
• Understanding the clinical presentation and outcomes of C-NS sepsis is crucial for effective management.

Purpose of the Study:

• To evaluate the incidence, clinical features, and outcomes of C-NS sepsis in newborn infants admitted to the Neonatal Intensive Care Unit (NICU).

Main Methods:

• Retrospective analysis of 2177 neonates admitted to the NICU from January 1989 to July 1990.
• Case records were reviewed for infants with positive blood cultures for C-NS.
• Infants were categorized into septicemic and bacteremic groups based on clinical and hematological findings.

Main Results:

• 74 (3.4%) neonates had positive blood cultures for C-NS; 58 (2.7%) had sepsis.
• Septicemia onset occurred later (mean 10.22 days) compared to bacteremia (1-4 days).
• Premature and low birth weight (LBW) infants constituted over two-thirds of sepsis cases.
• Clinical features included lethargy, poor feeding, fever, and apneic spells in very low birth weight infants.
• Prolonged IV fluid therapy, umbilical catheterization, and ventilator support were common preceding factors.
• Mortality was 17.24%, significantly higher in neonates with respiratory distress syndrome (RDS) and mechanical ventilation.
• Most C-NS isolates showed sensitivity to newer cephalosporins, ciprofloxacin, and amikacin.

Conclusions:

• C-NS sepsis is a serious concern in NICU settings, particularly affecting premature and LBW infants.
• Early recognition and appropriate antibiotic selection are vital for improving outcomes.
• Risk factors such as invasive procedures and prolonged IV therapy warrant careful consideration.
