ABSTRACT

BACKGROUND:

Immune thrombocytopenic purpura (ITP) is a frequently observed bleeding disorder in children. High dose intravenous immunoglobulin G (IVIG) has been used for the treatment of ITP since 1981, and now several methods of IVIG infusion are used. Since 1983, we have treated ITP patients with short-term and low-dose IVIG according to the individual patient's daily response. This study aimed to evaluate individual patient's response after IVIG for the prediction of chronic ITP.

METHODS:

We evaluated 259 childhood ITP patients retrospectively who were newly diagnosed at the Department of Pediatrics, Kyungpook National University Hospital from 1983 to 2012. We analyzed the individual response to treatment and current state of disease. We evaluated the time to reach desired platelet counts after treatment of IVIG, relapse rate and diagnosis of chronic ITP. The patients were classified into 2 groups according to the time to reach desired platelet counts (50,000/microL) after daily treatment of IVIG, rapid (1 or 2 doses) and slow responder (more than 3 doses).

RESULTS:

Among 182 patients followed up over 6 months, 41 patients (22.5%) were eventually diagnosed with chronic ITP. Hundred and two patients (56.7%) belonged to rapid response group, and 17 of them (16.7%) were diagnosed with chronic ITP. Eighty patients (44.4%) belonged to the slow response group, and 24 of them (30%) were diagnosed with chronic ITP, which were higher than the early response group (P=0.033).

CONCLUSION:

Individual response rate of IVIG treatment could be a useful predictor of chronic ITP, but this finding needs support from further studies.
