摘要:

目的 分析外周血黏膜相关恒定 T(mucosal associated invariant T,MAIT)细胞比例与慢加急 性肝衰竭(acute⁃on⁃chronic liver failure,ACLF)患者 90 d 预后的关系。方法 采用流式细胞术检测 51 ACLF 患者及 30 名健康对照组外周血 MAIT 细胞占 CD3+T 细胞比例,比较 ACLF 患者及对照组 MAIT 细胞的 表达水平,同时比较 ACLF 患者 MAIT 细胞比例与病毒感染、不同慢性肝病基础的差异。根据 90 d 的生存 情况分为好转组和死亡组,logistic 回归分析 ACLF 患者死亡的危险因素,并按 MAIT 细胞比例的中位数作 为分界值,将患者分为高表达和低表达两组,采用 Kaplan⁃Meier 法绘制生存曲线。结果 ACLF 患者外周 MAIT 细胞比例[(2.03 ± 1.19)%]较对照组[(5.07 ± 1.22)%]明显降低(P < 0.05),其改变与病毒感染无 关[(2.08 ± 1.27)% vs.(1.82 ± 0.81)%,P > 0.05]。有肝硬化基础的 ACLF 患者 MAIT 细胞水平明显低于无 肝硬化患者[(1.69 ± 0.84)% vs.(3.29 ± 1.49)%,P < 0.05],失代偿期肝硬化患者的MAIT细胞水平低于代偿 期肝硬化患者[(1.54 ± 0.80)vs.(2.18 ± 0.80)%,P < 0.05]。Logistic回归分析显示MAIT细胞比例、终末期肝 病评分模型(model for end⁃stage liver disease,MELD)评分是影响 ACLF 患者预后的危险因素(P < 0.05)。 根据入院时 MAIT 比例的中位数作为分界值(1.96%),将 ACLF 患者分为高 MAIT 组(≥ 1.96% 26 例)和低 MAIT 组(< 1.96% 25 例),采用 Kaplan⁃Meier 法绘制生存曲线,MAIT ≥ 1.96%生存率为 80.77%,而 MAIT < 1.96%则为 36.00%,高 MAIT 组与低 MAIT 组患者生存差异有统计学意义(P = 0.000 3)。结论 外周血 MAIT 细胞水平对于预测ACLF 患者90 d预后具有一定预测价值。

Abstract:

Objective To analyze the value of peripheral blood mucous ⁃associated invariant T(MAIT cell level on the 90⁃day prognosis of patients with acid⁃on⁃chronic liver failure(ACLF). Methods The ratio of MAIT cells to CD3+ T cells in peripheral blood of 51 ACLF patients and 30 healthy controls was determined by flow cytometry. The expression level of MAIT cells in ACLF patients and control subjects was compared. At the same time,the ratio of MAIT cells of ACLF patients was compared with that of patients with virus infection or other chronic liver diseases. According to the 90 ⁃ day survival,the patients were divided into improvement group and death group. After logistic regression analysis of risk factors for death in patients with ACLF,the patients were divided into high expression group and low expression group according to the median of MAIT cell proportion as the demarcation value. The Kaplan ⁃ Meier method was used to draw the survival curve. Results The proportion of MAIT cells in peripheral blood of ACLF patients(2.03 ± 1.19)% was significantly lower than that of control group (5.07 ± 1.22)%(P < 0.05),and the change was not related to virus infection[(2.08 ± 1.27)% vs.(1.82 ± 0.81)% P > 0.05]. MAIT cell level in ACLF patients with basic cirrhosis was significantly lower than that in patients without cirrhosis[(1.69 ± 0.84)% vs.(3.29 ± 1.49)%,P < 0.05]. MAIT cell level in decompensated cirrhosis patients(1.54 ± 0.80)% was lower than that in compensated cirrhosis patients(2.18 ± 0.80)%(P < 0.05). Logistic regression analysis showed that the proportion of MAIT cells and the model for end stage liver disease(MELD)score were risk factors for the prognosis of ACLF patients(P < 0.01). According to the median MAIT ratio at admission(1.96%),ACLF patients were divided into high MAIT group(≥ 1.96% ,26 cases)and low MAIT group(< 1.96%,25 cases). Kaplan⁃Meier method was used to draw the survival curve. The survival rate of MAIT ≥ 1.96% was 80.77%,while MAIT < 1.96% 36.00%,and the difference in survival between the high MAIT group and the low MAIT group was statistically significant(P = 0.000 3). Conclusion The level of MAIT cells in peripheral blood is of certain value in predicting the 90⁃day prognosis of ACLF patients.
