Isolated v-lesion presents diagnostic stratification and clinical challenges. We characterized allograft outcomes for this entity based on posttransplant time (early: ≤1 month vs late: >1 month) and compared its molecular phenotype with other v+ rejection forms. Using the NanoString B-HOT panel, we analyzed 92 archival formalin-fixed paraffin-embedded tissue kidney biopsies from 3 centers: isolated v-lesion (n = 23), antibody-mediated rejection (ABMR) v+ (n = 26), T cell–mediated rejection (TCMR) v+ (n = 10), mixed rejection v+ (n = 23), and normal tissue (n = 10). Six gene sets (ABMR, DSAST, ENDAT, TCMR, early/acute injury, late injury) were assessed. Early isolated v-lesions had the poorest 1-year death-censored graft survival compared with late isolated v-lesions or other rejections (P = .034). Gene set analysis showed lower TCMR-related gene expression in isolated v+ groups than TCMR and mixed rejection (P < .001). Both early- and late isolated v-lesions had lower ABMR-related gene expression than ABMR, mixed rejection, and TCMR (P ≤ .022). Late isolated v-lesions showed reduced DSAST and ENDAT gene expression versus ABMR (P ≤ .046) and decreased early/acute injury gene expression than early isolated v+, ABMR, TCMR, and mixed rejection (P ≤ .026). In conclusion, isolated v-lesions exhibit distinct gene expression patterns versus other rejection v+ forms. Early isolated v+ is associated with poorer prognosis and increased early/acute injury gene expression than late isolated v+, suggesting distinct etiologies.

v 病变的临床和分子谱



孤立的 V 形病变带来了诊断分层和临床挑战。我们根据移植后时间 (早期:≤1 个月 vs 晚期:>1 个月)表征了该实体的同种异体移植结果,并将其分子表型与其他 v+ 排斥反应形式进行了比较。使用 NanoString B-HOT 面板,我们分析了来自 3 个中心的 92 例存档福尔马林固定石蜡包埋的组织肾活检:孤立的 v 病变 (n = 23)、抗体介导的排斥反应 (ABMR) v+ (n = 26)、T 细胞介导的排斥反应 (TCMR) v+ (n = 10)、混合排斥反应 v+ (n = 23) 和正常组织 (n = 10)。评估了 6 个基因集 (ABMR、DSAST、ENDAT、TCMR、早期/急性损伤、晚期损伤)。与晚期孤立性 v 病变或其他排斥反应相比,早期孤立性 v 病变的 1 年死亡删失移植物生存率最差 (P = .034)。基因集分析显示,分离的 v+ 组中 TCMR 相关基因表达低于 TCMR 和混合排斥反应 (P < .001)。早期和晚期分离的 v 病灶的 ABMR 相关基因表达均低于 ABMR 、混合排斥反应和 TCMR (P ≤ .022)。晚期分离的 v 损伤显示 DSAST 和 ENDAT 基因表达低于 ABMR (P ≤ .046),早期/急性损伤基因表达低于早期分离的 v+ 、 ABMR 、 TCMR 和混合排斥反应 (P ≤ .026)。总之,分离的 v 损伤表现出与其他排斥 v+ 形式不同的基因表达模式。与晚期孤立 v+ 相比,早期孤立 v+ 与更差的预后和早期/急性损伤基因表达增加相关,提示不同的病因。
