OCHOA, Carlos D et al. Epidemiology of primary vasculitis in Colombia and its relation with reported for latin america. Rev.Colomb.Reumatol. [online]. 2009, vol.16, n.3, pp.248-263. ISSN 0121-8123.

Purpose: primary vasculitis occurs with variable expression in individual patients and regions, and variable frequency throughout the world. Their overall incidence has been calculated to be 40 cases per million populations. We sought to describe the frequency of vasculitis in Colombia and compare it with vasculitis reported from other countries of Latin America (LA). Methods: review of available published literature on vasculitis in LA from 1945 to 2007 in OLD Medline, Pub Med, BIREME, SciELO Colombia, LILACS, FEPAFEN, including publications in English, Spanish and Portuguese. The literature included published information from San Juan de Dios hospital, Bogota, Colombia, and unpublished cases submitted directly to the authors. We calculated the percentage of all cases which are reported from Colombia. Results: we identified 857 cases of primary vasculitis in Colombia. Takayasu arteritis was the most common vasculitis in 13.3% (114 cases) followed by Buerger's disease in 11.2% (96 cases), primary cutaneous vasculitis and polyarteritis nodosa in a 10% (86 cases) each. In children, the vasculitis was more frequent in Henoch Schonlein purpura in 24% (206 cases). In Latin America, 177 articles were published in 1605 reported cases. It showed increased presence of Takayasu's arteritis in Mexico and Brazil, and microscopic poliangeiitis in Peru and Chile. Conclusion: while the majority of publications on primary vasculitis are from Europe and North America, there is a substantial literature and experience with these disorders in LA. A considerable number of publications and cases have emerged from Colombia in recent years, including case descriptions of a recently described variant of nodular cutaneous vasculitis. Takayasu arteritis was the most frequently reported form of primary vasculitis overall, and also from Brazil and Mexico. However, ANCA related vasculitis were the most commonly reported forms in Chile and Peru instead. The greatest numbers of cases were reported from Mexico, the LA's most populous country, with Colombia a close second.
