A study by Peralta M et al. in 1997 concluded that 12.1% of cases of acute ITP developed SLE during a follow-up of 7.2 years.6 Study done by So Eun Jun et al. in 2008 in Korea showed that ANA positivity in ITP could be as high as 20.8% through progression to SLE was infrequent.7 Risk factors for the future development of SLE in ITP patients were studied by Hazzan et al. in 2006. This evidence concerns the gene BTG3 and autoimmune thrombocytopenic purpura.
