Disease burden and case management of bacterial meningitis among children under 5 years of age in Saudi Arabia.

OBJECTIVE

This study was designed to explore the case management and disease burden of bacterial meningitis among children below the age of 5 years in the Kingdom of Saudi Arabia.

METHODS

A prospective descriptive study was conducted during June 1999 through to May 2001 in 8 hospitals from 5 cities in different areas of the country. Those were, King Fahad Specialist Hospital and Maternity & Children Hospital, Buraidah, Belgorashi General Hospital and King Fahad Specialist Hospital, Al-Baha, Maternity & Children Hospital and Ohud Hospital, Al-Madina, Al-Qatif General Hospital in the Eastern Region and Prince Abdulrahman Bin Ahmed Alsudairy Central Hospital, Sakaka. The study population was 171,818 children under the age of 5 years.

RESULTS

During the study period 208 cases of bacterial meningitis were identified, 141 (67.8%) with a definite causative organism: Hemophilus influenzae type b, Neisseria meningitidis, Streptococcus pneumoniae and other bacterial species. The remaining 67 cases (32%) were labeled as aseptic meningitis. A considerable proportion of cases was found to have received an antibiotic prior to presentation. While symptoms such as fever or poor feeding were common among cases, meningeal signs were less prominent. A lumbar puncture was carried out on all cases to reach diagnosis by gram stain, latex agglutination test and cerebrospinal fluid (CSF) and blood cultures following standard procedures. The immediate burden of meningitis cases was found to be the lengthy stay of patients in the hospital wards and intensive care units. Some of the main causative agents were resistant to the conventional antimicrobial therapy, but susceptible to newer antibiotics.

CONCLUSION

The study being based on a population based surveillance gave a better overview on causative organisms of meningitis emphasizing that Gram stain, serology of CSF and culture (of CSF and blood) should be used. A high index of suspicion is needed to diagnose meningitis in children. Lumbar tap should be encouraged and supported in terms of training and more authorization to apply in diagnostic tests of such conditions. Audiometric measurement is a crucial need in the assessment of meningitis cases and in the process of their follow up. This type of service is clearly missing in our system. Influential steps are to be planned to avail this service.
