Abstract

CANTEROS, C. E. et al. Coccidioidomycosis in Argentina, 1892-2009. Rev. argent. microbiol. [online]. 2010, vol.42, n.4, pp.261-268. ISSN 0325-7541.

Clinical cases of coccidioidomycosis are rare in Argentina and are generally found in the large arid precordilleran area of the country. This study aims to perform a retrospective review of all coccidioidomycosis cases documented in the country from 1892 to 2009, and to describe those occurring in the last 4 years. One hundred and twenty eight cases were documented in the 117 year-period. Since the original description of the disease in 1892 until 1939, only 6 cases were registered; between 1940 and 1999, 59 (6-14/10 yrs) and the remaining 63 (49% of total cases) occurred in the last decade. The median age of 34 patients registered in 2006-2009 was 31 years (range: 7-89), male/female ratio was 1.3:1 and 12 patients were immunocompromised. Twenty-six cases were confirmed by direct microscopy and/or culture whereas the remaining ones by serology. All isolates were identified as Coccidioides posadasii. Thirty patients lived in a vast geographic region with epicenter in Catamarca Valley. Between 2006 and 2009, annual disease incidence rates in Catamarca Province increased from historical values below 0.5/100,000 to 2/100,000 inhabitants. Such increase suggests an emergency of coccidioidomycosis in that region.
