Penicillin-resistant pneumococcal infections in children.
Penicillin-resistant pneumococcal infections have been reported worldwide, but rarely reported in Taiwan. From 1990 to 1995, the rate of penicillin-resistant Streptococcus pneumoniae (PRSP) infections in our hospital increased from less than 10% during the first 2 years (1990-91) to 45% during the last 2 years (1994-95). From 1990 to 1995, twenty-four patients with systemic pneumococcal infections were diagnosed in the Department of Pediatrics at Mackay Memorial Hospital. Pneumococci were isolated from blood in 20 patients, cerebrospinal fluid in 12 patients, joint fluid in one patient and pleural effusion in one patient. Four patients had underlying diseases, including ileal atresia, Wiskott-Aldrich syndrome, congenital heart disease, and perilymph fistula. Of the 24 isolates of S. pneumoniae, 17 (70.8%) were intermediately penicillin resistant (minimum inhibitory concentrations between 0.1 and 1.0 microgram/mL), and 7 (29.2%) were highly resistant (minimum inhibitory concentrations > 1.0 microgram/ml). Fourteen patients recovered completely, two had minor sequelae, two had major sequelae, and six died. Four of the 12 patients with meningitis died. In this study, both the rate of PRSP as well as the mortality of patients with PRSP meningitis were high, as compared to previous reports. To reduce the mortality and morbidity of systemic pneumococcal infections, the oxacillin disc diffusion test is important in addition to appropriate antibiotic therapy.
