Corticosteroids have represented the mainstay for immunosuppression since the beginning of organ transplantation. However, these agents may be responsible of a number of invalidating and even life-threatening side effects. After the introduction of cyclosporine, some randomized trials have been attempted to avoid or withdraw corticosteroids. Meta-analyses of these studies showed that acute rejection was more frequent in patients who eliminated steroids than in patients who continued steroids. However, although graft survival was not affected by steroid avoidance, an increased risk of graft failure was reported in patients with late withdrawal of steroids. Only one multicenter trial provided a long-term follow-up of patients treated with the old formulation of cyclosporine. That study showed that, in spite of a higher incidence of rejection, in patients with an early avoidance of steroids, the 9-year graft survival rate was similar to that observed in patients given cyclosporine and steroids but with reduced risks of cardiovascular, ocular, and bone complications. A more recent study with everolimus and low-dose cyclosporine showed that the 3-year patient and graft survival rates were similar in patients who stopped steroids within 1 week after transplantation and in patients who continued low doses of prednisone. The available data indicate that an early elimination of corticosteroids is feasible today in many renal transplant recipients. A steroid-sparing strategy may reduce the side effects and improve the compliance of transplant recipients.
自器官移植开始以来,皮质类固醇一直是免疫抑制的主要手段。然而,这些药物可能会导致许多致残甚至危及生命的副作用。环孢素引入后,人们尝试了一些随机试验来避免或停用皮质类固醇。对这些研究的荟萃分析表明,停用类固醇的患者急性排斥反应比继续使用类固醇的患者更频繁。然而,尽管避免使用类固醇不影响移植物存活,但据报道,晚期停用类固醇的患者移植物失败风险增加。只有一项多中心试验对使用旧剂型环孢素治疗的患者进行了长期随访。该研究表明,尽管排斥反应发生率较高,但早期避免使用类固醇的患者9年移植物存活率与接受环孢素和类固醇治疗的患者相似,但心血管、眼部和骨骼并发症风险降低。一项关于依维莫司和低剂量环孢素的最新研究表明,移植后1周内停用类固醇的患者与继续使用低剂量泼尼松的患者3年患者和移植物存活率相似。现有数据表明,如今在许多肾移植受者中早期停用皮质类固醇是可行的。减少类固醇使用的策略可能会减少副作用并提高移植受者的依从性。
