Neonatal Meningitis: A Prospective Observational Study On Microbial Etiology, Cerebrospinal Fluid Pathology, And Clinical Outcomes

Le résumé fourni par la source

Background: Neonatal meningitis is a severe and potentially fatal condition that continues to pose a significant challenge in developing countries. Understanding the microbial etiology, cerebrospinal fluid (CSF) characteristics, and clinical outcomes is essential for optimizing treatment strategies and improving neonatal survival rates. Methods: This prospective observational study was conducted in multiple tertiary care centers across central India over one year. Neonates presenting with clinical signs suggestive of meningitis underwent lumbar puncture for CSF analysis. Microbiological testing, including Gram staining, culture, and PCR analysis, was performed to identify the causative pathogens. CSF parameters such as protein, glucose, and cell counts were documented. Clinical outcomes were evaluated based on recovery, neurological sequelae, and mortality rates. Results: Escherichia coli was identified as the predominant pathogen, followed by Klebsiella pneumoniae. Significant antibiotic resistance patterns were observed, particularly resistance to Ampicillin and Cefotaxime. Elevated CSF protein levels and reduced glucose concentrations were commonly observed in bacterial meningitis cases. Neonates treated with Ceftriaxone and Amikacin demonstrated the highest recovery rates, whereas those requiring Colistin and Tigecycline had poorer outcomes. The study highlighted a higher risk of prolonged hospitalization and complications in severe cases. Conclusion: This study underscores the critical need for improved diagnostic strategies, targeted antibiotic regimens, and enhanced neonatal care practices. Strengthening maternal screening programs and adopting emerging diagnostic technologies may significantly improve outcomes in neonatal meningitis cases.
