ABSTRACT
An unusually high incidence of septicemia due to multiresistant Klebsiella pneumoniae occurred in the Aristotle University Neonatology Department. Forty neonates suffered from 42 episodes of septicemia. Mortality was 43% ranging from 32% in neonates with birth weight (BW) ≥ 1500 g to 55% with < 1500 g. No differences were found between 17 neonates who died and 23 survivors. All isolates were resistant to aminoglycosides, third-generation cephalosporins, and aztreonam, but susceptible to imipenem and ciprofloxacin. The neonates with septicemia due to K. pneumoniae were matched 1:1 with neonates without septicemia (31 pairs) or with neonates with septicemia due to other organisms (8 pairs) according to BW and time of admission. Factors associated with septicemia were mechanical ventilation (p = 0.004) and ongoing parenteral nutrition (p = 0.027). In a multivariate model, nutrition exhibited no independent association after adjusting for ventilation. No differences were detected between the patients with Klebsiella septicemia and those with septicemia due to other organisms. Enhanced Infection Control measures and a temporary change of antibiotic policy reduced this serious complication. Three small outbreaks of multiresistant K. pneumoniae previously reported in neonates are reviewed.
