Abstract |
Among 48 children with I.T.P (26 acute, 10 chronic and 12 undetermined), the antiplatelet antibody
test (APA) was qualitatively studied by indirect immunofluorescent method in 34 patients of which
only 25 patients (18 acute and 7 chronic) were able to follow-up. The overall positivity of APA was
36% and there was no relationship with disease chronicity. Intravenous r-globulin was given at a
dose of 400 mg/kg/day for 5 days in 14 patients (11 acute and 3 chronic) and 13 patients showed
response (10 complete and 3 partial responses). One patient with acute I.T.P. was not responded to I.
V. r-globulin treatment, but showed complete response to following steroid treatment. The higher the
initial platelet count, the better the response to I.V. r-globulin treatment (p < 0.05). The response rate
within a week after initiating treatment was 92.8% in I.V. r-globulin treated group and 41.2% in
steroids (p< 0.025). And the complete response rate of 76.9% was noted in I.V. r-globulin treated
group and 35.7% in steroids (p < 0.05). The detection of APA was not useful in predicting response to
certain treatment or selecting treatment method. |
