We conducted a retrospective study to determine the extent of penicillin and ceftriaxone non-susceptible Streptococcus pneumoniae bacteremia in a tertiary care medical center in the city of Riyadh, Kingdom of Saudi Arabia.METHODS: We reviewed 172 episodes of Streptrococcus pneumoniae bacteremic diseases involving 160 hospitalized patients at King Faisal Specialist Hospital and Research Centre, Riyadh, Kingdom of Saudi Arabia, over a 5 year period between January 1995 through to December 1999. Patients' characteristics and underlying illnesses of those patients with bacteremias and meningitis caused by Streptococccus pneumoniae as well as antimicrobial susceptibility were examined.RESULTS: The majority of patients affected with Streptococcus pneumoniae bacteremia were children <5 years of age (number=91, 53%). Malignant diseases were the main underlying diagnosis in our patient population affected with pneumoncoccal bacteremia (number=46, 27%). Overall (51%) of the isolates were penicillin non-susceptible; of these (7%) were highly resistant. The overall resistance rate to ceftriaxone was 7%.CONCLUSION: With the high prevalence in Streptococcus pneumoniae antimicrobial resistance to penicillin and ceftriaxone, it is important to continue surveillance of infections caused by Streptococcus pneumoniae, and also we recommend that guidelines for treatment and prevention of pneumococcal infection must be addressed by health care and public health agencies.
