Assessment of antimicrobial treatment of acute typhoid and paratyphoid fevers in Britain and The Netherlands 1971-1980.

The response of 310 patients with typhoid or paratyphoid fevers to current antibiotic therapy was studied retrospectively. Most patients were of Asian or European origin, thus reflecting the areas in which they were infected. Of the 244 patients with well-recorded therapy 63% were treated with chloramphenicol, 22% with co-trimoxazole and the remainder with various penicillins. There was little difference in response in terms of resolution of fever. Symptoms persisted in only two of 153 (1.3%) patients given chloramphenicol but side-effects led to a change of treatment in nine of these patients. Co-trimoxazole was not significantly inferior and amoxycillin performed well, but the small number of cases treated with ampicillin or mecillinam did not respond as well as those treated with the other drugs.
