The Latin American Registry on Aplastic Anemia (LARAA) is a collaboration across 10 Latin American countries to capture aplastic anemia data. The initiative aims to create a “Proof of Concept” registry that will demonstrate collaboration across Latin America, establish common standards for data collection, and allow participants to retain ownership of their data. The first phase of the initiative is a three-year retrospective study that is providing baseline data on the distribution of aplastic anemia and its specific characteristics in the region. This will be followed by the implementation of a prospective protocol in the coming year.
