Summary

The current study goal is to examine the effect of Cephalosporins, Azithromycin and the combination of both on typhoid fever therapy in endemic population. The investigator's hypothesize that the combination of azithromycin and ceftriaxone may prove superior to each drug, ceftriaxone or azithromycin, alone.

Detailed description

Typhoid Fever is a highly prevalent infection in the Indian subcontinent. Due to multidrug resistant strains in these areas, third generation cephalosporins, such as ceftriaxone, are the treatment of choice. However, the latter regimen exhibits a slow response with mean time of 5 to 7 days or even longer to defervescence, which could be attributed to poor penetration capability of the drug into cells, and thus difficulty to eradicate the bacteria from the intracellular niche. Attempts have been made to overcome this setback by introducing alternative antibiotic regimens, such as azithromycin. However studies comparing between azithromycin and a third-generation cephalosporin for the treatment of typhoid fever in adult population in the Indian subcontinent are lacking. Over the last few years our approach towards non-immunized travelers, who acquired typhoid fever in the Indian subcontinent, was to administer a combination therapy of intravenous ceftriaxone with oral azithromycin. The rationale of this dual regimen was its pharmacokinetic profile, which suggests a complimentary action of the two agents - ceftriaxone on the extracellular compartment and azithromycin on the intracellular compartment. Moreover, in our clinical experience, preliminary published data has proven combination therapy significantly superior to ceftriaxone alone albeit in a small group of travelers. In the current study the investigators intend to compare the efficacy of ceftriaxone vs. azithromycin and vs. combined therapy of both agents for the treatment of uncomplicated typhoid fever in terms of time to defervescence. 4 different treatment strategies will be examined (as mentioned in the arm section). All participants will be checked for vital signs, will undergo physical examination, ECG, laboratory testing, blood, urine and stool culture and tests for susceptibility to antibiotics.
