Abstract:
Bacterial meningitis continues to be associated with high morbidity and mortality rate worldwide, especially in the pediatric age group. This study was performed to identify the microbial etiologies of meningitis among 31 children, who were admitted in the Emergency Ward of a referral pediatric hospital in Iran. Culture identification showed that Streptococcus pneumoniae (12 subjects), Haemophilus influenzae (11 subjects) were the most common bacteria, followed by Escherichia coli (7 cases) and Neisseria meningitidis (only one case). Antibiotic susceptibility tests revealed that vancomycin had the best effect on S. pneumoniae in comparison with other antibiotics, whereas H. influenzae and E. coli were more susceptible to ceftriaxone, ceftazidime, and ceftizoxime than other antibiotics. In conclusion, despite the advances in antibiotic therapy and vaccine development, bacterial meningitis still is a health problem. S. pneumoniae, H. influenzae, and N. meningitidis are the main sources of bacterial meningitis, but other organisms such as E. coli should also be suspected, when a case is admitted to a referral pediatric hospital.
Insights
Bacterial meningitis in children remains a significant global health concern. Streptococcus pneumoniae and Haemophilus influenzae were the most frequent causes identified in Iranian pediatric patients.
Area of Science:
- Pediatrics
- Infectious Diseases
- Microbiology
Background:
- Bacterial meningitis presents a substantial global challenge, particularly impacting pediatric populations with high rates of illness and death.
- Despite advancements in vaccines and treatments, bacterial meningitis persists as a critical public health issue worldwide.
Purpose of the Study:
- To determine the microbial causes of meningitis in children admitted to a pediatric referral hospital in Iran.
- To analyze the antibiotic susceptibility patterns of common bacterial pathogens responsible for pediatric meningitis.
Main Methods:
- A study was conducted on 31 children diagnosed with meningitis and admitted to the Emergency Ward of a pediatric referral hospital in Iran.
- Microbial etiologies were identified using culture techniques, and antibiotic susceptibility testing was performed on isolated pathogens.
Main Results:
- Streptococcus pneumoniae (38.7%) and Haemophilus influenzae (35.5%) were the predominant bacterial pathogens.
- Escherichia coli (22.6%) was also a notable cause, while Neisseria meningitidis was identified in only one case (3.2%).
- Vancomycin demonstrated significant efficacy against S. pneumoniae, whereas H. influenzae and E. coli showed higher susceptibility to ceftriaxone, ceftazidime, and ceftizoxime.
Conclusions:
- Bacterial meningitis continues to pose a significant threat to children, necessitating ongoing surveillance and treatment strategies.
- While S. pneumoniae, H. influenzae, and N. meningitidis are primary concerns, E. coli should also be considered in the differential diagnosis of pediatric meningitis, especially in referral centers.
- Tailored antibiotic selection based on susceptibility patterns is crucial for effective management of pediatric bacterial meningitis.
