Bone marrow transplantation for the treatment of acute nonlymphoblastic leukemia in children aged less than 2 years 总被引:1,自引:1,他引:0
Eleven children with acute nonlymphoblastic leukemia in first remission who were less than 2 years of age at diagnosis were treated with 120 mg/kg of cyclophosphamide, 12-Gy fractionated total-body irradiation, and marrow transplantation. Seven patients remain in complete remission from 3.5 to 13.8 years posttransplant, four for more than 6.75 years. The immediate posttransplant course was relatively uncomplicated in surviving patients. No child developed severe graft-v-host disease. The major long-term side effect has been a slowing in growth. Although the prognosis for such children with conventional chemotherapy remains poor, intensive cytotoxic therapy and marrow transplantation offers an alternative therapy with a chance for cure. 相似文献

Herpes simplex virus lesions recur in 8–30% of infants who receive a course of parenteral antiviral therapy for an initial infection. Long-term acyclovir is used by some clinicians to prevent recurrent Herpes simplex disease. We describe nine infants who were treated with doses of oral acyclovir which were chosen to achieve 2-h post-plasma concentrations of ≥2 μg/ml. Eight infants had Herpes simplex encephalitis and one had multiple recurrences of dermal and ocular disease. The target plasma concentration was chosen in order to attain acyclovir cerebrospinal fluid distribution (≤50% plasma) for an estimated ID30 of Herpes simplex II strains of 0.1–0.5μg/ml. One of nine patients failed to achieve the target plasma acyclovir concentration. One of nine patients developed symptomatic recurrence of the central nervous system disease and none of the remaining eight patients experienced recognized dermal or neurologic recurrence of Herpes simplex disease. Renal and neurologic status were routinely monitored and no signs of acyclovir toxicity were observed. Plasma concentration of acyclovir ≥2μg/ml may be achieved with average oral doses of 1340mg/m2 /dose (1000–1740 mg/m2 /dose) given at 12-h intervals. 相似文献
