Cytomegalovirus (CMV) is the most common viral infection during the post-transplant period, and it is one of the major causes of morbidity and mortality in kidney transplantation. In this study, the incidence and impact of pre-emptive and prophylactic approaches and long-term effects on graft and patient survival of CMV infection were investigated. Among 493 adult kidney transplant recipients, pretransplant CMV IgG-negative patients and patients with a follow-up shorter than a month were excluded. The patients were divided into 2 groups: pre-emptive group (n = 187, regular screening and acyclovir 400 mg twice daily for 6 months), and prophylaxis group (n = 275, valganciclovir 450 mg/d for 3 months). The pre-emptive group was screened for CMV with either pp65 antigenemia or CMV DNA. There were 462 patients, and mean follow-up was 37.7 months. There were more CMV infections in the pre-emptive group than in the prophylaxis group (n = 56, 30.1% vs n = 12, 4.4%, respectively; P < .001). Late CMV infections were significantly more frequent in the prophylaxis group (10 of 12, 83.3%) than in the pre-emptive group (8 of 56, 14.3%, P < .001). In multivariate analysis, valganciclovir prophylaxis was associated with a lower CMV infection (relative risk [RR]: 0.18, 95% confidence interval [CI] 0.08 to 0.39, P < .001). Delayed graft function was the only independent risk factor for graft loss during the follow-up on multivariate Cox regression analysis (RR: 2.66, 95% GA 1.17 to 6.04, P = .02). Valganciclovir prophylaxis was more protective against CMV infection than the pre-emptive approach. Neither prophylaxis/pre-emptive approaches nor CMV infection had negative effect on graft and patient survival.
巨细胞病毒(CMV)是移植后时期最常见的病毒感染,也是肾移植发病和死亡的主要原因之一。在本研究中,调查了抢先治疗和预防方法的发生率及影响,以及CMV感染对移植物和患者生存的长期影响。在493例成年肾移植受者中,排除了移植前CMV IgG阴性患者和随访时间短于1个月的患者。患者分为2组:抢先治疗组(n = 187,定期筛查并口服阿昔洛韦400 mg,每日2次,共6个月)和预防组(n = 275,口服缬更昔洛韦450 mg/d,共3个月)。抢先治疗组采用pp65抗原血症或CMV DNA筛查CMV。共有462例患者,平均随访37.7个月。抢先治疗组的CMV感染多于预防组(分别为n = 56,30.1% 与n = 12,4.4%;P <.001)。预防组的晚期CMV感染明显多于抢先治疗组(12例中的10例,83.3% 对比56例中的8例,14.3%,P <.001)。多因素分析中,缬更昔洛韦预防与较低的CMV感染相关(相对危险度[RR]:0.18,95%置信区间[CI] 0.08至0.39,P <.001)。在多因素Cox回归分析中,移植肾功能延迟是随访期间移植物丢失的唯一独立危险因素(RR:2.66,95% GA 1.17至6.04,P =.02)。缬更昔洛韦预防比抢先治疗方法对CMV感染更具保护作用。预防/抢先治疗方法和CMV感染对移植物和患者生存均无负面影响。
