BACKGROUND: We analyzed the clinical characteristics and prognostic factors of community-acquired spontaneous bacterial meningitis (CASBM) in adult diabetic patients. PATIENTS AND METHODS: Over a period of 15 years, 47 adult diabetic patients with CASBM were identified. The clinical characteristics, laboratory data and therapeutic outcome of these 47 patients were statistically analyzed. RESULTS: The 47 patients were 31 men and 16 women, aged 22 to 79 years, and they accounted for 38.5% (47/122) of our adult patients with culture-proven CASBM. The most common causative pathogen was Klebsiella pneumoniae (n = 32), followed by pathogens of the streptococcal species (n = 6). Besides classic manifestations of bacterial meningitis, bacteremia and focal suppuration, especially liver abscess, were common features in this group of patients. Liver cirrhosis and/or alcoholism were the other frequent underlying conditions. 27 patients survived in the course of therapy. The prognostic factors with statistical significance were glucose ratio and cerebrospinal fluid (CSF) white blood cell (WBC) count. CONCLUSION: This study showed the high incidence of diabetes mellitus (DM) among the adult patients with CASBM in Taiwan. K. pneumoniae was the most frequent causative pathogen. Bacteremia and focal suppuration, especially liver abscess, were common findings. The values of glucose ratio and CSF WBC count had a statistically significant influence on the prognosis of our patients.
