Genetic Epidemiology of Chagas Disease Progression

Description: Genome-wide association study to identify genetic determinants of progression to the cardiac form of Chagas disease in a sample of 1000 infected individuals who belong to large extended pedigrees and 500 uninfected individuals in the same pedigrees. The most promising genes will be resequenced, and a confirmatory study will be conducted in 500 unrelated infected individuals with severe cardiac disease and 500 unrelated infected asymptomatic controls.

Partner Organization: Centro de Pesquisas René Rachou, FIOCRUZ, Belo Horizonte, Brazil
International Site: Brazil

Genetics of Hypertension in Blacks

Description: Conducts a genome-wide association study for high-blood pressure (hypertension) in the Yoruba population of Nigeria to help understand the genetic factors that may influence the likelihood of developing hypertension. Also, a large replication sample will be examined from West Africa, and from population samples from Brazil, the Caribbean and the US.
Lead Institution: Loyola University Chicago, Maywood, Illinois, USA
Partner Organization: University of Sao Paulo, Sao Paulo, Brazil; University of the West Indies, Mona, Jamaica; University of Warwick, Coventry, UK; Montreal Heart Institute, Montreal, Canada; University of Ibadan, Ibadan, Nigeria

Clinical Studies

FREEDOM Trial: Future Revascularization Evaluation in Patients With Diabetes Mellitus: Optimal Management of Multivessel Disease

Purpose: Address the critically important problem of how to best revascularize diabetic individuals with multivessel coronary artery disease. The main objective is to evaluate whether percutaneous coronary intervention with drug-eluting stenting is more or less effective than the existing standard of care, coronary artery bypass graft.
Foreign Sites: Argentina, Australia, Belgium, Brazil, Canada, Chile, Colombia, Czech Republic, France, Germany, India, Ireland, Israel, Italy, Mexico, New Zealand, Poland, Spain, Switzerland, United Kingdom

International HIV-associated Opportunistic Pneumonias (IHOP) Study

Purpose: Create an international, multi-center, longitudinal cohort that reflects the HIV/AIDS epidemic in Africa, Europe, and North America to study pneumocystis carinii pneumonia and opportunistic pneumonias.
Sites: Uganda, United Kingdom
