Abstract:
Objective To confirm the role of human parvovirus B 19 ( B19) infection in childhood immune thrombocytopenia ( ITP) patients.Methods A total of 416 cases of newly diagnosed childhood ITP patients from Jan .2011 to Dec.2013 had been summarized to be cases group , Then a total of 130 childhood patients with common respiratory tract infection were selected randomly as the control group . All patients had been divided in grouped by age as <1 years group(n=187), 1-3 years group(n=127), 3-7 years group(n=71), and 7-14 years group(n=31).The incidence rate of B19 infection in all age groups, the prognosis conditions in B19 infection positive and negative groups after the same therapy protocol were obserred .Results The B19 infection rate had no statistical significance in re-search groups and control groups .And no significant difference in the same age groups compared with control groups (all P>0.05) was found.All the ITP patients had not been given anti -B19 treatment.The PLT remission rate,respectively, after treated with the same pro-tocol including glucocorticoid and/or immunoglobulin had a declining trend as the ages increasing .The B19 infection groups of all ages al-so had no significant difference PLT remission rate had been confirmed in non -B19 infection patients in each age groups (all P>0.05). Conclusions B19 infection may not be a major cause in childhood newly ITP , and treatment protocol with no anti -B19 treatment had no influence on the clinical curative efficacy .
