Arthritis Rheumatol:自身免疫或炎性全身疾病中利妥昔单抗引起的HHV-8肿瘤

2017-07-21 xiangting MedSci原创

在利妥昔单抗治疗前,高皮肤分型和存在HHV-8风险的患者必须进行仔细筛查。

HHV-8也称卡波西肉瘤(KS)相关性疱疹病毒,涉及KS和包括多中心Castleman病(MCD)和原发性渗出性淋巴瘤(PEL)在内的其他肿瘤。利妥昔单抗目前常用于治疗几种自身免疫性或炎性疾病和体液器官排斥反应。自身免疫/炎性疾病或体液器官排斥中使用利妥昔单抗诱发的新生HHV-8肿瘤尚未有报道。

在这项回顾性研究中,研究人员报道了在利妥昔单抗治疗后5名HIV阴性的男性HHV-8肿瘤患者的临床、病毒学及病理学结果。

所有患者均因以前的治疗而存在免疫缺陷,使用类固醇和/或因疾病进展或排斥使用包括利妥昔单抗的免疫抑制治疗。出现HHV-8肿瘤的中位时间是利妥昔单抗治疗后的6个月(范围3至13个月)。4名患者有至少有1个HHV-8危险因素,包括Fitzpatrick皮肤分型> 3(n = 3)和同性恋(n = 1)。4名患者出现KS伴皮肤损伤(n = 4)和内脏受累(n = 2),1名患者发展为实体PEL。

所有患者均停用利妥昔单抗,并在可行时减少免疫抑制治疗。在中位随访20个月后,2名患者死亡。KS完全缓解(n = 1),部分缓解(n = 1),1名患者进展。

在利妥昔单抗治疗前,高皮肤分型和存在HHV-8风险的患者必须进行仔细筛查。对于有HHV-8肿瘤风险的患者,尤其在非淋巴瘤性疾病中,必须仔细评估利妥昔单抗的安全性。
