BACKGROUND Recent findings strongly support hematopoietic stem cell transplantation (HSCT) in patients with severe presentation of LPS-responsive beige-like anchor protein (LRBA) deficiency, but long-term follow-up and survival data beyond previous patient reports or meta-reviews are scarce for those patients who do not receive a transplant. OBJECTIVE This international retrospective study was conducted to elucidate the longitudinal clinical course of patients with LRBA deficiency who do and do not receive a transplant. METHOD We assessed disease burden and treatment responses with a specially developed immune deficiency and dysregulation activity score, reflecting the sum and severity of organ involvement and infections, days of hospitalization, supportive care requirements, and performance indices. RESULTS Of 76 patients with LRBA deficiency from 29 centers (median follow-up, 10 years; range, 1-52), 24 underwent HSCT from 2005 to 2019. The overall survival rate after HSCT (median follow-up, 20 months) was 70.8% (17 of 24 patients); all deaths were due to nonspecific, early, transplant-related mortality. Currently, 82.7% of patients who did not receive a transplant (43 of 52; age range, 3-69 years) are alive. Of 17 HSCT survivors, 7 are in complete remission and 5 are in good partial remission without treatment (together, 12 of 17 [70.6%]). In contrast, only 5 of 43 patients who did not receive a transplant (11.6%) are without immunosuppression. Immune deficiency and dysregulation activity scores were significantly lower in patients who survived HSCT than in those receiving conventional treatment (P = .005) or in patients who received abatacept or sirolimus as compared with other therapies, and in patients with residual LRBA expression. Higher disease burden, longer duration before HSCT, and lung involvement were associated with poor outcome. CONCLUSION The lifelong disease activity, implying a need for immunosuppression and risk of malignancy, must be weighed against the risks of HSCT.

根据免疫缺陷和失调活性(IDDA)评分评估,采用各种治疗方式后,76例患者的LRBA缺乏症的长期结局。

背景技术最近的发现强烈支持严重表现为LPS反应性米色样锚蛋白(LRBA)缺乏症的患者的造血干细胞移植(HSCT),但长期的随访和生存数据超出了先前的患者报告或荟萃评价。对于那些没有接受移植的患者而言稀缺。目的进行这项国际回顾性研究,以阐明接受和不接受移植的LRBA缺乏症患者的纵向临床病程。方法我们通过特别开发的免疫缺陷和失调活动评分评估疾病负担和治疗反应,反映出器官受累和感染的总数和严重程度,住院天数,支持治疗的要求以及性能指标。结果:29个中心的76例LRBA缺乏症患者(中位随访时间为10年;范围为1-52),2005年至2019年接受了24例HSCT。HSCT术后总体生存率(中位随访时间为20个月)为70.8%(24名患者中的17名); 所有死亡均归因于与移植相关的早期非特异性死亡。目前,未接受移植的患者中有82.7%(52岁的患者中有43岁;年龄在3-69岁之间)还活着。在17名HSCT幸存者中,7例完全缓解,5例未经治疗而部分缓解良好(总共17人中有12人[70.6%])。相比之下,未接受移植的43位患者中只有5位(11.6%)没有免疫抑制。在HSCT中幸存的患者的免疫缺陷和失调活动评分显着低于接受常规治疗的患者(P = 0。005)或接受abatacept或西罗莫司治疗(与其他疗法相比)的患者,以及残留LRBA表达的患者。较高的疾病负担,HSCT之前的持续时间较长以及肺部受累与不良预后相关。结论必须权衡终生疾病活动性,这意味着需要免疫抑制和恶性肿瘤的风险,必须权衡HSCT的风险。
