[Five days ceftibuten versus 10 days penicillin in the treatment of 2099 patients with A-streptococcal tonsillopharyngitis].

Abstract

Unlabelled: Group A Streptococci have remained sensitive to penicillins and other betalactam antibiotics, e. g. cephalosporins. Since the beginning of the 1950s oral penicillin V given three times daily in a dose of 50,000 IU daily has been the drug of choice against Group A streptococcal infection. The German Society for Pediatric Infectious Diseases (DGPI) undertook a large scale multicenter randomized study of culture-proven A-streptococcal tonsillopharyngitis to compare the efficacy and safety of a five day regimen of ceftibuten (9 mg/kg KG, once daily) with 10 days of penicillin V (50,000 I.E./kg KG, divided in three doses), testing for equivalence of clinical and bacteriological efficacy. A one year follow-up served to assess poststreptococcal sequelae like rheumatic fever or glomerulonephritis.

Results: The clinical efficacy at the clinical end-point 7-9 days after end of treatment was 86.9% (419/482) for ceftibuten and 88.6% (1,198/1,352) for penicillin V. This result is statistically equivalent (P = 0.0152). Resolution of clinical symptoms was significantly faster in the ceftibuten group (P = 0.043/Fisher-Test) and compliance was significantly superior as well (P (0.001). Eradication of group A streptococci at an early control 2-4 days after end of treatment was not equivalent, 78.49% for ceftibuten and 84.42% for penicillin V (P = 0.5713). Both eradication rates were comparable 7-8 weeks after end of treatment (84.65%, 375/443 ceftibuten vs. 86.82%, 1,067/1,229 penicillin V), the difference not being significant. No cases of poststreptococcal sequelae, e.g. rheumatic fever or glomerulonephritis, attributable to either ceftibuten or penicillin were observed in the course of the study.
