Abstract:
Neonatal meningitis is rare but devastating disease. Multidrug-resistant (MDR, multi-drug resistant) bacteria are a major global health risk. We report an Escherichia coli meningitis isolate with multiple resistance patterns and unusual serotype (O75) that caused sudden neonatal death. The isolate was resistant to antibiotics other than cefoperazone/sulbactam and imipenem, challenging the combination of antibiotics commonly used in the empirical treatment of neonatal sepsis. Despite aggressive symptomatic and supportive treatment of the infant based on laboratory tests and clinical practice, the infant eventually died. This is the first case of meningoencephalitis due to serotype O75 reported in China. The presence of highly pathogenic multidrug-resistant microorganisms isolated in neonates underscores the need to implement rapid resistance diagnostic methods and should prompt consideration of alternatives to empiric treatment of neonatal bacterial meningitis.
Insights
A rare multidrug-resistant Escherichia coli meningitis case in a neonate highlights treatment challenges. Despite intensive care, the infant died, emphasizing the need for rapid diagnostics and alternative treatments for neonatal bacterial meningitis.
Area of Science:
- Neonatal infectious diseases
- Bacteriology
- Antimicrobial resistance
Background:
- Neonatal meningitis is a severe infection with high mortality.
- Multidrug-resistant (MDR) bacteria pose a significant global health threat.
- Current empirical antibiotic regimens for neonatal sepsis are increasingly challenged by MDR pathogens.
Observation:
- A case of sudden neonatal death due to meningitis caused by an Escherichia coli isolate is reported.
- The E. coli isolate exhibited unusual serotype O75 and multidrug resistance patterns.
- The pathogen was resistant to most common antibiotics, except cefoperazone/sulbactam and imipenem.
Findings:
- The multidrug-resistant E. coli O75 isolate caused fatal meningoencephalitis in a neonate.
- Treatment failure occurred despite aggressive symptomatic and supportive care.
- This represents the first reported case of serotype O75 E. coli meningoencephalitis in China.
Implications:
- The emergence of highly pathogenic MDR bacteria in neonates necessitates rapid diagnostic methods for antimicrobial resistance.
- Current empiric treatment strategies for neonatal bacterial meningitis require re-evaluation.
- Development of novel therapeutic approaches is crucial to combat MDR infections in vulnerable newborns.
