From 1/1999 to 11/2000, 120 patients had diagnosed new ITP (male 33.3%), female (66.7%). All these patients had checked antigen-antibody of B-C hepatitis and evaluated correclation between ITP and carrier antigen Hepatitis B-C. Results of our study:- There were significant difference between ITP disease and carrier anti-HCV but there were not significant difference between ITP disease and carrier antigen (HbsAg). Cortcoid therapy is still a respond to the patient ITP (HbsAg+) but no responds to the patients ITP antiHCV+.
