In Reply, IgA Vasculitis (Henoch-Sch önlein Purpura) in Argentina

As noted by Brom et  al,1 limited observational studies investigating IgA vasculitis have been reported from Latin America,2-4 and these cohorts have thus far focused only on pediatric populations. These aforementioned studies present data similar to that reported by Brom et al, as well as our group, demonstrating a less severe renal outcome among pediatric cases of IgA vasculitis. Although the comparative data between the pediatric and adult groups in the report by Brom et al needs to be considered in the context of the small size of the adult population presented (n=11), these findings remain consistent wi th other reports, including ours, that adult-onset IgA vasculitis appears to be associated with more frequent renal involvement and a more aggressive course.
