efficacy of dexamethasone treatment in adult patients with acute bacterial meningitis

ABSTRACT

To evaluate the efficacy of dexamethasone added to the treatment of adult patients with bacterial meningitis in our region. One hundred and forty-four patients were randomized prospectively and evaluated to determine the efficacy of dexamethasone treatment in adult patients with acute bacterial meningitis at Dicle University Hospital, Diyarbakir, Turkey between January 2000 and December 2004. While the first group received ceftriaxone 4 gr/day plus dexamethasone, the second group received ceftriaxone 4 gr/day only Dexamethasone was given I 10-15 minutes before the first 8 mg dose of antibiotic treatment. It was continued at 16 mg/day for 3 days. The study included 144 patients with the diagnosis of acute bacterial meningitis. Cerebrospinal fluid [CSF] was analyzed at the time of admission, after 24-48 hours [Table 1], and at the end of treatment. Accordingly, CSF leukocyte level was found to be 1710 +/- 2140/mm3 in group 1 receiving dexamethasone treatment compared to 1950 +/- 2244/mm[3] in group 2 [p=0.001]. The consciousness in the group receiving dexamethasone improved significantly more rapidly than the control group [p=0.001]. While mortality was 9.7% in the patient group receiving dexamethasone it was 16.7% in the control group, however, it was not significant [p=0.093]. The use of dexamethasone in adult patients is still under debate, and the administration of dexamethasone 10-15 minutes before antibiotherapy to unconscious patients in a poor state of health, is effective in the clinical improvement of the patient
