Argentinian Prospective Registry of Patients With Lupus

SLE

In Latin America, information about patients with systemic lupus erythematosus (SLE) is limited. Multicenter studies are needed to obtain real world data '' and to carry out longer follow-ups. The purpose of this project is to design a cohort of Argentinian patients with SLE to describe our real setting and to identify possible limitations in access to specialized consultations and treatments.

A longitudinal and multicenter cohort study of patients with systemic lupus erythematosus (SLE) is planned, with a follow-up of for 5 years. The data will be obtained from the clinical history of each patient. The responsible for data collection will always be a physician with experience in the management of patients with SLE and who has received training for data loading. The data will be collected through the an electronic case report form (eCRF) specially designed for this record and which in turn will facilitate the control of the data and the generation of inquiries to the researchers.
