Sparfloxacin as alternative treatment to standard therapy for community-acquired bacteremic pneumococcal pneumonia.
OBJECTIVE: To assess the effectiveness of a single daily dose of sparfloxacin in comparison with standard antibacterial therapy for the treatment of pneumococcal bacteremic community-acquired pneumonia (CAP). METHODS: The results were analyzed of four comparative trials in CAP, in which 107 adult patients with CAP confirmed by blood cultures positive for Streptococcus pneumoniae were included. Sparfloxacin was given at a loading dose of 400 mg followed by 200 mg daily. Comparator drugs included amoxycillin 3 g/day, amoxycillin/clavulanate 1.5/0.375 g/day and erythromycin 2 g/day. Dosing was for 7--14 days (mean 10 days). Success was determined by a combination of clinical and microbiological assessment and radiologic changes. RESULTS: Sparfloxacin was as effective as the comparator drugs, with an overall success rate of 80% at the end of treatment (comparators 78%), and a 79% success rate at follow-up (76% for comparators). There were no pneumococcal isolates resistant to sparfloxacin, but eight of 56 were either resistant (four) or had reduced susceptibility to penicillin G, and two strains were resistant to erythromycin. Tolerance to sparfloxacin was good, with fewer patients reporting drug-related adverse events (15.8%) than with the comparator drugs (33.3%). CONCLUSIONS: This analysis suggests that sparfloxacin would be an alternative candidate for empirical therapy in moderately severe CAP.
