title: Seronegative arthritis in Latin America: a current review.
abstract: In many Latin American countries seronegative arthritis, especially the spondyloarthritides (SpA), is commonly characterized by associated axial and peripheral involvement. In this article, the authors review the ethnic distribution of the population and the different SpA in 10 Latin American countries, and the main characteristics of the Ibero-American Registry of Spondyloarthropathies (RESPONDIA) compared with other international registries. The peripheral component of SpA is more frequent in mixed-race populations, whereas psoriatic arthritis is significantly more frequent in countries with predominantly white populations.
