Immune reconstitution may differ following cord blood transplantation (CBT) and bone marrow transplantation (BMT), and this may lead to a difference in varicella zoster virus (VZV) disease rates. One hundred fourteen VZV seropositive children received a CBT (37 patients), or a T-replete BMT (77 patients) at our institution. Patients did not received specific VZV disease prophylaxis. VZV disease was diagnosed by immunofluorescence or culture in 41 (36%) patients. In multivariate analysis, VZV disease was more frequent in older children (relative risk [RR] 1.11 per year; 95% confidence interval [CI], 1.04-1.18; P = .002), and after CBT (RR 2.27; 95% CI, 1.18-4.34; P = .013). The cumulative incidence of VZV disease at 3 years posttransplant was 46% following CBT. VZV disease incidence was 71% in CBT patients over 10 years old at transplant. Visceral dissemination occurred in 7 patients (6 CBT and 1 BMT) (P = .005). VZV disease is thus more frequent and more severe after CBT than after BMT.
脐带血移植(CBT)和骨髓移植(BMT)后的免疫重建可能有所不同,这可能导致水痘带状疱疹病毒(VZV)疾病发生率的差异。114名VZV血清阳性儿童在我们机构接受了CBT(37例患者)或T细胞充足的BMT(77例患者)。患者未接受特定的VZV疾病预防措施。41名(36%)患者通过免疫荧光或培养诊断出VZV疾病。在多变量分析中,年龄较大的儿童VZV疾病更常见(相对风险[RR]为每年1.11;95%置信区间[CI],1.04 - 1.18;P = 0.002),且在CBT后(RR 2.27;95% CI,1.18 - 4.34;P = 0.013)。移植后3年VZV疾病的累积发病率在CBT后为46%。移植时年龄超过10岁的CBT患者中VZV疾病发病率为71%。7名患者(6名CBT患者和1名BMT患者)发生了内脏播散(P = 0.005)。因此,CBT后VZV疾病比BMT后更频繁且更严重。
