Chlamydia Clinical Trial
Official title:
Eliminating Trachoma With Repeat Mass Drug Treatment
The WHO has initiated a program to eliminate trachoma, blinding eye infection caused by Chlamydia trachomatis, in large part by mass distributions of oral azithromycin. The proposed study will determine the frequency and treatment target of community-wide mass antibiotic treatment. We will also study the impact of mass antibiotic distribution on antibiotic-resistance in pneumococcus.
The proposed study is a group-randomized trial to determine the frequency and treatment
target of community-wide mass antibiotic treatment to eliminate trachoma. We will also study
the impact of community-wide antibiotic distribution on antibiotic-resistance in
pneumococcus. Communities in Goncha Siso Enese district of East Gojam Zone, Ethiopia will be
randomly assigned to different treatment schemes and monitored to study the following
research questions:
Specific Aim 1. To determine whether biannual mass treatments is more likely to eliminate
ocular chlamydia from hyper-endemic communities than annual mass treatments.
Specific Aim 2. To determine whether children form a core group for the transmission of
trachoma.
Specific Aim 3. To determine whether latrine construction prevents the return of infection
into a community after mass treatment.
Specific Aim 4. To determine the effect of mass azithromycin treatments on antibiotic
resistance in pneumococcus and the reduction in mortality.
Specific Aim 5. To determine whether annual mass treatments are more likely to eliminate
ocular chlamydia from hyper-endemic communities than biennial mass treatments.
