Brief Summary

Abstract: Background The current practice in Senegal is to use broad-spectrum antibiotics including amoxicillin and/or cotrimoxazole in case of non-malarial fevers. First-line treatment with doxycycline has cured such patients. The investgators aimed to determine the efficacy of a single dose of doxycycline compared to a 5-day amoxicillin course for the treatment of fever.

Detailed Description

Methods The investgators conducted a non-inferiority, open-label, randomized controlled trial in patients aged \> 8 years recruited from dispensaries in the rural area of Niakhar, Senegal. Participants were enrolled based on a body temperature \> 37.5°C, as assessed using an electronic axillary thermometer. Febrile patients with a positive malaria test were excluded from the study. Participants were randomly assigned (1:1) to receive either a single dose of doxycycline (30 mg/kg) or a five-day course of amoxicillin (20 mg/kg) by a computer-generated random number sequence. The investgators monitored participants at days 2 and 7 post-treatment. The primary outcome was cure after 7 days, defined as a body temperature \< 37.5°C. The investgators used a non-inferiority margin of 10%. This trial was approved by the national ethic committees of the Senegalese Ministry of Health in May 2017 (0026/MSAS/DPRS/CNERS, March, 7, 2016).

Non-inferiority comparison of the efficacy between Doxycycline and Amoxicillin after 7 days of follow-up7 days follow up

The endpoint was cure at day-7 post-inclusion. Clinical cure was defined as a body temperature \< 37.5°C. Clinical failure was defined as persistence of fever \> 37.5°C at day-7. The investgators used a non-inferiority margin of 10%.
