Abstract

Twenty-eight cases of bacterial meningitis during the recent ten years were analyzed retrospectively, and the following results were obtained. 1. Pathogens were as follows; H. influenzae 13 (46.4%), S. pneumoniae 8 (28.6%), S. agalactiae 4 (14.3%), E. coli 2 (7.1%), and L. monocytogenes 1 case (3.6%). 2. Twelve out of the thirteen H. influenzae cases were caused by serotype b (Hib), and 2 strains were beta-lactamase producer. Fifty percent of the S. pneumoniae cases were caused by penicillin-resistant strains. And all these resistant strains belonged to serotype 19 or 23. 3. Underlying diseases related to the onset of meningitis were found in 46% of the cases, and these consisted of CNS shunt operated 5, asplenia or polysplenia 2, Mondini's anomaly 1, sacral dermal sinus 1, and neonate 4 cases. 4. Prognosis of these cases were three deaths, four with neurologic sequelae, and twenty-one complete recoveries. 5. On admission, 85% (17/20) of the cases were diagnosed correctly by the rapid antigen detection. Sensitivity and specificity of the rapid antigen detection by using latex particle agglutination is 90% and 100% in the Hib cases, and 83% and 100% in the S. pneumoniae cases respectively. Moreover, the bacteriologically unknown 2 cases caused by parenteral partial treatment were also diagnosed by the detection of antigen in concentrated urine.
