Summary
A study was conducted with the cooperation of 31 university hospitals and 44 general
hospitals in Japan on high-dose immunoglobulin therapy for idiopathic thrombocytopenic
purpura (ITP).
Sulfonated immunoglobulins were administered to 177 patients, comprising 102 children
and 75 adults for two to seven days, and a favorable rise of platelet count was found
in 114 (64.4%) of these patients.
In particular, of the 107 patients who had not responded favorably to adrenocortico-steroids
therapy, 63 cases showed a favorable rise of platelet count. And of the 14 patients
who had not responded favorably to splenectomy, 6 cases showed a favorable rise of
platelet count.
In the majority of cases the platelet count fell to its pretreatment level within
one month after the start of sequence of administration.
Although a dosage of 400 mg/kg/day was suitable for most patients, the wide range
of individual responses suggested the desirability of determining an optimal dose
for each patients.
