ABSTRACT
<p><b>OBJECTIVE</b>Idiopathic thrombocytopenic purpura (ITP) is a hemorrhagic disease in children with blood platelets redundant destruction caused by chaotic immunological mechanism. However, some patients with ITP with negative platelet-associated antibody and ineffective adrenal cortical hormone therapy probably have special pathogenesis. It is indicated that the human cytomegalovirus (HCMV) can incubate in haemopoietic stem cell/ancestral cell to inhibit its generation and differentiation. Therefore, the study was designed to investigate HCMV-late mRNA expression in megakaryoblast for the purpose of examining the pathogenesis of ITP and to examine the effectiveness of ganciclovir on ITP.</p><p><b>METHODS</b>Colony forming unit-megakaryocyte (CFU-MK) of 46 ITP patients with HCMV infection were incubated. Reverse transcription-polymerase chain reaction (RT-PCR) was subsequently used for HCMV-late mRNA detection. Ganciclovir therapy was given to both positive group and negative group for comparison of therapeutic effectiveness.</p><p><b>RESULTS</b>Nineteen out of 46 CFU-MK culture cell specimens with positive HCMV-DNA by PCR or positive CMV-IgM by enzyme linked immunosorbent assay (ELISA) from serum of peripheral blood showed positive for HCMV-late mRNA. While, the remaining 27 were negative. Sixteen positive responders to ganciclovir therapy were observed amongst those with positive HCMV-DNA. Whereas, only 4 positive responders to ganciclovir therapy were noticed amongst those with negative HCMV-DNA. The curative effectiveness in positive group was significantly higher than that in negative group (P < 0.01).</p><p><b>CONCLUSION</b>HCMV can directly infect CFU-MK, which might be one of the mechanisms responsible for ITP. Ganciclovir is an effective therapy resulting in an increase in thrombocyte in ITP patients whose HCMV-late mRNA was positive in their CFU-MK.</p>
