Epstein-Barr virus (EBV)-associated posttransplant lymphoproliferative disorder (EBV-PTLD) is a serious complication in lung transplant recipients (LTRs) associated with significant mortality. We performed a single-center retrospective study to evaluate the risks for PTLD in LTRs over a 7-year period. Of 611 evaluable LTRs, we identified 28 cases of PTLD, with an incidence of 4.6%. Kaplan-Meier analysis showed a decreased freedom from PTLD in idiopathic pulmonary fibrosis (IPF)-LTRs (P < .02). Using a multivariable Cox proportional hazards model, we found IPF (hazard ratio [HR] 3.51, 95% confidence interval [CI] 1.33-8.21, P = .01) and alemtuzumab induction therapy (HR 2.73, 95% CI 1.10-6.74, P = .03) as risk factors for PTLD, compared to EBV mismatch (HR: 34.43, 95% CI 15.57-76.09, P < .0001). Early PTLD (first year) was associated with alemtuzumab use (P = .04), whereas IPF was a predictor for late PTLD (after first year) (P = .002), after controlling for age and sex. Kaplan-Meier analysis revealed a shorter time to death from PTLD in IPF LTRs compared to other patients (P = .04). The use of alemtuzumab in EBV mismatch was found to particularly increase PTLD risk. Together, our findings identify IPF LTRs as a susceptible population for PTLD. Further studies are required to understand the mechanisms driving PTLD in IPF LTRs and develop strategies to mitigate risk.

特发性肺纤维化肺移植受者患 EBV 相关移植后淋巴组织增生性疾病的风险增加,生存率更差。

EB 病毒 (EBV) 相关的移植后淋巴组织增生性疾病 (EBV-PTLD) 是肺移植受者 (LTR) 的一种严重并发症,死亡率很高。我们进行了一项单中心回顾性研究,以评估 7 年期间 LTR 中 PTLD 的风险。在 611 个可评估的 LTR 中,我们确定了 28 个 PTLD 病例,发生率为 4.6%。Kaplan-Meier 分析显示特发性肺纤维化 (IPF)-LTR 中 PTLD 的自由度降低 (P < .02)。使用多变量 Cox 比例风险模型,我们发现 IPF(风险比 [HR] 3.51,95% 置信区间 [CI] 1.33-8.21,P = .01)和阿仑单抗诱导治疗(HR 2.73,95% CI 1.10-6.74, P = .03) 作为 PTLD 的危险因素,与 EBV 不匹配相比(HR:34.43,95% CI 15.57-76.09,P < .0001)。早期 PTLD(第一年)与使用阿仑单抗相关(P = .04),而 IPF 是晚期 PTLD(第一年后)的预测因子(P = .002),在控制了年龄和性别后。Kaplan-Meier 分析显示,与其他患者相比,IPF LTR 患者死于 PTLD 的时间更短 (P = .04)。发现在 EBV 错配中使用阿仑单抗特别会增加 PTLD 风险。总之,我们的研究结果将 IPF LTR 确定为 PTLD 的易感人群。需要进一步研究以了解在 IPF LTR 中驱动 PTLD 的机制并制定降低风险的策略。发现在 EBV 错配中使用阿仑单抗特别会增加 PTLD 风险。总之,我们的研究结果将 IPF LTR 确定为 PTLD 的易感人群。需要进一步研究以了解在 IPF LTR 中驱动 PTLD 的机制并制定降低风险的策略。发现在 EBV 错配中使用阿仑单抗特别会增加 PTLD 风险。总之,我们的研究结果将 IPF LTR 确定为 PTLD 的易感人群。需要进一步研究以了解在 IPF LTR 中驱动 PTLD 的机制并制定降低风险的策略。
