[Low-dose prednisolone therapy for idiopathic thrombocytopenic purpura]

Prednisolone (PSL) is widely used for the treatment of idiopathic thrombocytopenic purpura (ITP). We compared the effects of a relatively low dose (0.5 mg/kg/day, LD group) of PSL and the conventional dose (1.0 mg/kg/day, CD group) on 59 ITP patients. Twenty-six patients were treated with low-dose PSL, and 23 patients with the conventional dose. No statistically significant difference was observed in the complete remission rates for the LD group (35%) and the CD group (39%). However, the mean duration of hospitalization was significantly (p < 0.001) shorter for LD group patients than for patients in the CD group (20 days versus 50 days, respectively). In conclusion, low-dose PSL may be as effective as the conventional dose and capable of reducing the cost of hospitalization, thus, improving the quality of life for patients with ITP.
