BACKGROUNDS/AIMS: Recurrent HCV-cirrhosis occurs in a substantial proportion of transplant recipients, with higher rates reported in patients who had recently received a transplant. Over-immunosuppression has been implicated in this more unfavorable outcome. To determine whether the implementation of specific measures aimed at reducing or avoiding negative predictive variables is associated with an improvement in the outcome of recurrent hepatitis C.
Comparative study between a cohort of patients who had recently received a transplant (2001-2004) and a historical group of HCV-infected patients transplanted before the implementation of two simple measures (1999-2000): (i) use of dual initial immunosuppression (steroids + cyclosporine neoral or tacrolimus); (ii) slow steroid tapering (>6 months). Yearly biopsies were performed in these recipients, and only those with at least one protocol biopsy and those with cholestatic hepatitis (regardless of follow-up) were included in the study. End-point: rate of HCV-related severe disease (defined as bridging fibrosis, cirrhosis or fibrosing cholestatic hepatitis) within the first year post-transplantation.
Severe disease was significantly lower in this cohort compared to the historical group (26/90, 29% vs 25/52, 48%; p=0.02). While other factors remained unchanged between the two cohorts, the proportion of patients on triple-quadruple regimes and the number of boluses of methyl-prednisolone were lower and the duration of prednisone therapy longer in more patients who had recently received a transplant.
Improving the outcome of recurrent hepatitis C may be achieved by reducing overall immunosuppression and avoiding abrupt variations in immunosuppression.
背景/目的:相当一部分移植受者会出现复发性丙型肝炎肝硬化,近期接受移植的患者报告的发生率更高。免疫抑制过度被认为与这种更不利的结果有关。为了确定实施旨在减少或避免负面预测变量的具体措施是否与丙型肝炎复发的预后改善相关。
对近期接受移植的一组患者(2001 - 2004年)与在实施两项简单措施之前移植的丙型肝炎感染患者的历史组(1999 - 2000年)进行比较研究:(i)使用双重初始免疫抑制(类固醇 + 新山地明或他克莫司);(ii)缓慢减少类固醇剂量(>6个月)。对这些受者进行年度活检,仅将至少有一次方案活检的患者以及患有胆汁淤积性肝炎的患者(无论随访情况如何)纳入研究。终点:移植后第一年内丙型肝炎相关严重疾病的发生率(定义为桥接纤维化、肝硬化或纤维化胆汁淤积性肝炎)。
与历史组相比,该队列中的严重疾病发生率显著更低(26/90,29% 对 25/52,48%;p = 0.02)。虽然两个队列之间的其他因素保持不变,但近期接受移植的更多患者中,接受三联 - 四联方案的患者比例和甲泼尼龙的推注次数更低,泼尼松治疗的持续时间更长。
通过降低总体免疫抑制并避免免疫抑制的突然变化,可能实现丙型肝炎复发预后的改善。
