Objective: To investigate the role of virus infections in the occurrence of childhood idiopathic thrombocytopenic purpura(ITP).

Methods: Human parvovirus B19(HPV B19), Epstein-Barr virus (EBV), cytomegalovirus (CMV) and hepatitis B virus (HBV) were detected in 32 children with acute ITP by using polymerase chain reaction (PCR) and ELISA skills.

Results: Positive HPV B19-DNA was observed on 8 cases (25.0%) in the ITP group and 1 in the control group (P<0,05). Positive EBV-DNA, CMV-DNA and HBV-antigens were detected on 2, 3 and 2 cases, respectively. The total positive rate of these 4 viruses was 46.9%(15/32).

Conclusions: The pathegenesis of nearly 1/2 childhood ITP cases probably correlates with virus infections, specially HPV B19 infection.
