【Abstract】 ObjectiveTo observe the efficacy and side effect of DA/HA regimen chemotherapy for the treatment of refractory and relapsed paroxysmal nocturnal hemoglobinuria (PNH). Methods Eight patients with refractory and relapsed PNH were treated with DA/HA regimen chemotherapy. Three patients were treated with DA(DNR 40 mg/d, i.v.drip, the first and the second day; 20 mg/d,i.v.drip, the third day; Ara-C 100?mg/d, i.v.drip, for 5 days) and 5 patients with HA (HHT 2～3 mg/d, i.v. drip, for 5 days; Ara-C 100 mg/d, i.v.drip,for 5 days).Results All the 8 patients responded well: the PNH clone was diminished in five patients. Hemolysis was remitted in 6 cases. Five patients showed improvement in hematological parameters. The dosage of corticosteroid was decreased in all of them. No serious side effect was revealed. Conclusion DA/HA regimen chemotherapy was safe and effective for refractory and relapsed PNH patients.更多还原
