摘要
为探讨异基因外周血造血干细胞移植(allo-PBSCT)后12个月内患者免疫重建特点及其与供受者年龄、供受者间HLA相容性、移植物抗宿主病(GVHD)及病毒感染的关系,随访37例异基因造血干细胞移植患者,用流式细胞术测定移植后1、3、6及12个月的T细胞亚群(CD3+、CD4+、CD8+)、B细胞(CD19+)及NK(CD16+CD56+)细胞,用散射比浊法检测免疫球蛋白IgG、IgA及IgM水平。结果显示,移植后1个月CD3+细胞的百分比为(47.5±23.2)%,3个月为(75.1±6.4)%,6个月为(69.7±12)%,12个月为(71.7±4.2)%。移植后1个月CD4+细胞百分比为(13.3±6.4)%,3个月为(20.2±11.4)%,6个月为(18.4±9.3)%,12个月为(29.1±8.7)%;移植后1个月CD8+细胞百分比为(43.1±17.4)%,3个月为(42.6±16.9)%,6个月为(46.9±10.3)%,12个月为(47±5.6)%;移植后1个月CD16+CD56+细胞百分比为(14.4±8.4)%,3个月为(15.9±7.6)%,6个月为(14.7±6.6)%,12个月为(13.6±3.4)%;移植后1个月CD19+细胞百分比为(6.4±5.6)%;3个月为(11.7±2.4)%,6个月为(13.3±7.3)%,12个月为(16.7±5.7)%。血清免疫球蛋白检测结果显示:移植后1个月IgA为(0.37±0.14)g/L,3个月为(0.28±0.21)g/L,6个月为(0.42±0.18)g/L,12个月为(0.53±0.34)g/L;移植后1个月IgG为(12.7±3.8)g/L,3个月为(16.3±5.2)g/L,6个月为(14.3±6.2)g/L,12个月为(15.4±6.9)g/L。移植后1个月IgM为(0.56±0.24)g/L,3个月为(0.64±0.16)g/L,6个月为(1.1±0.35)g/L,12个月为(1.2±0.28)g/L。大于等于45岁的患者T细胞亚群检测和血清免疫球蛋白与小于45岁患者比较无差异。发生慢性GVHD的患者移植后12个月CD19+细胞低于未发生的患者。HLA单倍体相合移植的患者CD4+及CD19+细胞恢复较HLA全相合患者明显延迟。8例患者发生带状疱疹,发生疱疹前3月内的CD4+/CD8+细胞比值中位数为0.39(0.24-0.55),显著低于未发生带状疱疹的对照组移植后6个月的CD4+/CD8+细胞比值中位数0.50(0.21-2.79)(p=0.034)。带状疱疹组CD4+细胞计数为(0.949±0.198)×109/L,显著低于未发生
This study was purposed to investigate immune reconstitution at 12 months after allogeneic peripheral blood stem cell transplantation (aII-PBSCT) and its relation with the influencing factors such as age, HLA compatibility, graft versus host desease and viral infection. The T lymphocyte subgroups (CD3 ^+, CD4^+, CD8 ^+), B lymphocyte(CD19^+) and NK (CD16^+ CD56^+) cells in peripheral blood and serum immunoglobulin concentrations (IgG, IgA and IgM) of 37 patients were analyzed by flow cytometry and scatter turbidimetry, respectively at 1,3,6 and 12 months after transplantation. The results showed that CD3 ^+ cell percentage was (47.5 ± 23.2)% at 1 month, (75.1 ± 6.4) % at 3 months, (69.7 ± 12 ) % at 6 months and (71.7 ± 4.2 ) % at 12 months. CD4 ^+ cell percentage was ( 13.3 ± 6.4) % at 1 month. ( 20.2 ± 11.4) % at 3 months. ( 46.9 ± 10.3 ) % at 6 months and ( 29.1 ± 18.7 ) % at 12 months. CD8 ^+ cell percentage was (43.1 ± 23.2) % at 1 month, (42.6 ± 16.9) % at 3 months, (69.7 ± 12) % at 6 months and (47 ±5.6)% at 12 months. CD16^+56^+cell percentage was (14.4±8.4)% at 1 month,(15.9±7.6)% at 3 months, (14.7 ±6.6)% at 6 months and (13.6 ±3.4)% at 12 months. CD19^+cell percentage was (6.4 ±5.6)% at 1 month,(11.7 ± 2.4) % at 3 months, ( 13.3 ± 7.3 ) % at 6 months and ( 16, 7 ± 5.7 ) % at 12 months. The serum concentration of IgA was (0.37 ± 0.14)g/L at 1 month,(0.28 ± 0.21) g/L at 3 months, (0.42 ±0. 18) g/L at6 months and (0.53 ±0.34) g/L at 12 months. The serum concentration of IgG was ( 12.7 ± 3.8 ) g/L at 1 month, ( 16.3 ± 5.2) g/L at 3 months, ( 14.3 ± 6.2) g/L at 6 months and (15.4 ±6.9) g/L at 12 months. The serum concentration of IgM was (0.56 ±0.24)g/L at 1 month,(0.64 ±0.16) g/L at 3 months, (1.1 ±0.35) g/L at 6 months and (1.2 ±0.28) g/L at 12 months. There were no significant differences between percenta
