Trachoma Clinical Trial
Official title:
Nepal Elimination of Trachoma Study
The main purpose of this study is to determine if ocular Chlamydia trachomatis infection can
be eliminated in communities in Nepal following mass antibiotic distributions with
azithromycin. The investigators will study both clinical trachoma and ocular C. trachomatis
infection. The overall objective is to determine if the current World Health Organization
(WHO) treatment strategy results in elimination of trachoma and infection.
1. The investigators hypothesize that 24 communities in Kanchanpur, Kailali, and Achham
districts of Nepal which receive mass antibiotic treatments will achieve elimination of
trachoma as a public health problem (clinical disease <5% in children 1-9 years old)
more frequently than communities which have not received antibiotic treatments.
2. The investigators hypothesize that infection with C. trachomatis will be undetectable
in all members within a community following mass treatment as determined by the most
highly sensiti1. The investigators hypothesize that 24 communities in Kanchanpur,
Kailali, and Achham districts of Nepal which receive mass antibiotic treatments will
achieve elimination of trachoma as a public health problem (clinical disease <5% in
children 1-9 years old) more frequently than communities which have not received
antibiotic treatments.
2. The investigators hypothesize that infection with C. trachomatis will be undetectable in
all members within a community following mass treatment as determined by the most highly
sensitive nucleic acid amplification testing available (mRNA-based APTIMA and DNA-based
AMPLICOR PCR).ve nucleic acid amplification testing available (mRNA-based APTIMA and
DNA-based AMPLICOR PCR).
Here we evaluate whether ocular chlamydia infection and clinical trachoma are eliminated from 24 communities in western Nepal following a mass antibiotic distribution program. It is unknown if repeated treatments should continue or can be stopped thereby minimizing side effects and the high cost of medicine distribution. The investigators plan to randomize individuals to two groups to study the effects of a mass antibiotic distribution program: 1) treatment of antibiotics and 2) delayed treatment of antibiotics (after 4-6 months). ;
