Pyogenic meningitis in children in north-western Ethiopia

Area of Science:

• Pediatrics
• Infectious Diseases
• Epidemiology

Background:

• Acute pyogenic meningitis is a significant cause of childhood morbidity and mortality globally.
• Bacterial meningitis presents a substantial public health challenge, particularly in resource-limited settings.
• Understanding causative pathogens and their epidemiological patterns is crucial for effective intervention.

Purpose of the Study:

• To investigate the etiological agents and clinical outcomes of acute pyogenic meningitis in children.
• To determine the most prevalent bacterial pathogens and their associated case fatality rates.
• To analyze demographic factors influencing meningitis incidence and mortality in pediatric populations.

Main Methods:

• A 5-year retrospective study was conducted from 1990 to 1994.
• Data were collected from all pediatric cases of acute pyogenic meningitis admitted to a district hospital in north-western Ethiopia.
• Causative bacteria were identified, and case fatality rates were calculated for different pathogens and age groups.

Main Results:

• 132 cases of pyogenic meningitis were identified, with causative bacteria identified in 64% of patients.
• Haemophilus influenzae (40%) was the most common pathogen, followed by Neisseria meningitidis (36.4%) and Streptococcus pneumoniae (20%).
• Overall case fatality rate was 28%, with significantly higher mortality (38.4%) in children under 1 year compared to those over 1 year (13.8%).

Conclusions:

• Haemophilus influenzae, Neisseria meningitidis, and Streptococcus pneumoniae are key pathogens causing childhood pyogenic meningitis in this Ethiopian region.
• Infants below one year of age face a substantially higher risk of mortality from pyogenic meningitis.
• These findings underscore the need for targeted prevention and treatment strategies for bacterial meningitis in pediatric populations in similar settings.
