A total of 108 children aged 4-17 years were randomized to receive 7 days o
f azithromycin (10 mg/kg/day; maximum, 500 mg/day) or ceftriaxone (75 mg/kg
/day; maximum, 2.5 g/day), to assess the efficacy of the agents for the tre
atment of uncomplicated typhoid fever. Salmonella typhi was isolated from t
he initial cultures of blood samples from 64 patients. A total of 31 (91%)
of the 34 patients treated with azithromycin and 29 (97%) of the 30 patient
s treated with ceftriaxone were cured (P >.05). All 64 isolates were suscep
tible to azithromycin and ceftriaxone, Of the patients treated with ceftria
xone, 4 subsequently had relapse of their infection. No serious side effect
s occurred in any study subject. Oral azithromycin administered once daily
appears to be effective for the treatment of uncomplicated typhoid fever in
children. If these results are confirmed, the agent could be a convenient
alternative far the treatment of typhoid fever, especially in individuals i
n developing countries where medical resources are scarce.
