Details and patient eligibility

About

EVITA is a multicentric Latin-American prospective cohort on chronic hypersensitivity pneumonitis. EVITA's objective is to identify phenotypes and/or endotypes associated with different disease trajectories measured primarily by forced vital capacity (FVC) during a 24 month follow-up period. Other secondary measures of disease progression will also be investigated such as imaging, time to death or lung transplantation, and patient-reported outcomes

Enrollment: 150 estimated patients

Sex: All

Ages: 18 to 99 years old

Volunteers: No Healthy Volunteers
