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.
Condition | Intervention | Phase |
---|---|---|
Trachoma Chlamydia |
Drug: Mass treatment with oral azithromycin to an entire community |
Phase IV |
Study Type: | Interventional |
Study Design: | Treatment, Randomized, Single Blind, Dose Comparison, Parallel Assignment, Safety/Efficacy Study |
Official Title: | Eliminating Trachoma With Repeat Mass Drug Treatment |
Estimated Enrollment: | 36000 |
Study Start Date: | June 2006 |
Estimated Study Completion Date: | November 2009 |
Estimated Primary Completion Date: | November 2009 (Final data collection date for primary outcome measure) |

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.
Ages Eligible for Study: | 1 Year and older |
Genders Eligible for Study: | Both |
Accepts Healthy Volunteers: | Yes |
Inclusion Criteria:
• All residents residing in the state-teams which are randomly selected for this study.
Exclusion Criteria:
Individuals in these three exclusion criteria will not be given the study antibiotic azithromycin, but offered the current WHO-recommended alternative treatment to azithromycin for active trachoma, which is 1% tetracycline eye ointment, to be used twice a day, topically to both eyes, for six weeks. Note that the exclusion criteria refer to the exclusion to the treatment drug, but not to the monitoring, treatment of trachoma, and examinations.
