A randomized placebo-controlled study of enalapril in the treatment of erythrocytosis after renal transplantation 总被引:1,自引:0,他引:1
Beckingham I. J.; Woodrow G.; Hinwood M.; Rigg K. M.; Morgan A. G.; Burden R. P.; Broughton-Pipkin F. 《Nephrology, dialysis, transplantation》1995,10(12):2316-2320
BACKGROUND: Erythrocytosis is a common complication of renal transplantationwith an incidence of up to 17%. It is associated with an increasedrisk of complications due to thromboembolic events and has traditionallybeen treated by intermittent venesection. More recently, angiotensin-convertingenzyme inhibitors have been shown to cause a fall in haematocritin a number of groups of subjects and some uncontrolled studieshave shown these drugs to be of possible therapeutic benefitin post renal transplant erythrocytosis. METHODS: We performed a randomized double-blind placebo-controlled studyin 25 patients with post-transplant erythrocytosis. Subjectsreceived either 2.5 mg of enalapril daily or a placebo for 4months and all patients completed the study period without anyserious adverse effects. RESULTS: Haematocrit fell from 52.7 (±SEM 0.7) to 47.1 (±1.8) at 1 month and 46.1 (± 1.2) after 4 months in patientsreceiving enalapril, with no change in the placebo group (P=0.004).We did not demonstrate any change in serum erythropoietin ineither group. CONCLUSION: Angiotensin-converting enzyme inhibitors are a safe and effectiveform of treatment for erythrocytosis developing after renaltransplantation. The mechanism of action, however, is not mediatedby changes in erythropoietin production and remains uncertain. 相似文献

目的观察低分子肝素治疗肺心病继发红细胞增多症的临床疗效。方法将42例慢性肺源性心脏病继发红细胞增多症患者随机分为治疗组21例,对照组21例。对照组给予常规治疗(氧疗、控制感染、扩张血管、纠正止心衰、纠正酸碱失衡及电解质紊乱)。治疗组在常规治疗的基础上加用低分子肝素5 000 IU腹壁皮下注射,1次/12 h,10~14 d为1疗程。结果治疗组:显效13例,有效7例,无效l例,总有效率95.2%;对照组:显效10例,有效5例,无效6例,总有效率71.4%。两组比较有显著差异(P<0.05)。结论低分子肝素佐治慢性肺源性心脏病继发红细胞增多症安全有效。 相似文献

PTE is defined as hematocrit >51% or hemoglobin >17 g/dL after renal transplantation. Risk factors include native kidneys with adequate erythropoiesis pretransplant, smoking, renal artery stenosis, and cyclosporine treatment. We report the case of a 14‐yr‐old female kidney transplant patient, with triple therapy immunosuppression and stable graft function who developed PTE at 12 months post‐transplant with hemoglobin 17.3 g/dL, hematocrit 54.2%, stable graft function, and normotensive with normal cardiac echocardiogram and erythropoietin levels. The only risk factor found was tobacco use. As she had no spontaneous improvement, enalapril treatment was started at 19 months post‐transplant with a hemoglobin level of 17.5 g/dL and hematocrit 53%; by 23 months post‐transplant, hemoglobin lowered to 15 g/dL and hematocrit to 44.5% and continued to be in normal range thereafter. PTE is a rare condition in childhood and can be successfully treated with enalapril. 相似文献

Results are reported of studies of the hemoglobin from one member of a Canadian family with a mild erythrocytosis. This variant, which accounted for about 40% of the hemoglobin, could be separated from Hb A and Hb A2 by cation-exchange chromatography. Micro methodology allowed the characterization of a Leu----Val replacement at position beta 96(FG3). Hb Regina has an increased oxygen affinity, which adequately explains the hematological observations. 相似文献
