  • Expression of B-cell maturation antigen mRNA in Peripheral Blood Mononuclear Cells in Patients with Systemic Lupus Erythematosus

    【摘要】 目的 检测B细胞成熟抗原(BCMA)mRNA在系统性红斑狼疮(SLE)患者外周血单个核细胞(PBMC)的表达水平,探讨BCMA在SLE发病中的意义。 方法 纳入2006年1-11月收治的36例SLE患者,同期17例健康志愿者作为对照组,采用半定量RT-PCR法检测外周血单个核细胞中BCMA mRNA的表达,并与SLE疾病活动指数(SLEDAI)进行相关性分析。 结果 SLE患者组BCMA mRNA表达水平(0.598±0.230)均明显高于正常对照组(0.411±0.309)(Plt;0.05)。SLE患者BCMA mRNA表达水平与SLEDAI评分无相关性(P=0.590)。 结论 SLE患者BCMA mRNA表达水平的增高,可能在SLE的发病机制中具有一定的作用。【Abstract】 Objective To detect the mRNA expression of B-cell maturation antigen (BCMA) in peripheral blood mononuclear cells (PBMC) in patients with systemic lupus erythematosus (SLE), and explore the role of BCMA in the pathogenesis of SLE. Methods From January 2006 to November 2006 the expression of BCMA mRNA in PBMC of 36 patients with SLE and 17 normal controls were measured by half-quantitative RT-PCR. The linear correlation between the expression of BCMA mRNA and SLE disease activity index (SLEDAI) was assessed. Results The level of BCMA mRNA (0.598±0.230) in PBMC significantly increased in SLE patients compared with that in the normal controls (0.411±0.309) (Plt;0.05). The expression of BCMA mRNA in SLE patients showed no correlation with SLEDAI score (P=0.590). Conclusion The results suggest that the expression of BCMA mRNA might play an important role in the pathogenesis of SLE.

  • Efficacy and safety of salvage therapeutic regimens for the relapsed/refractory diffuse large B cell lymphoma: a network meta-analysis

    ObjectiveTo analyze the efficacy and safety of various treatment strategies for patients with refractory/recurrent diffuse large B-cell lymphoma (r/r-DLBCL) by network meta-analysis. MethodsThe PubMed, EMbase and Cochrane Library databases were searched to collect randomized controlled trials (RCTs) and clinical controlled trials related to the objectives of the study from inception to November 16th, 2022. After two investigators independently screened the literature, extracted data and evaluated the risk of bias of the included studies, a network meta-analysis was performed using R 4.2.2 software. ResultsA total of 8 RCTs and 11 non-randomized controlled trials were included, involving 2 559 cases. The treatment regimen included chemotherapy, immunochemotherapy, chemotherapy combined with ADC, immunochemotherapy combined with ADC, ASCT based regimen, CAR-T based regimen, ASCT combined with CAR-T, immunomodulators, small molecule inhibitors, and rituximab combined with small molecule inhibitors. The ranking probability results showed that the top three complete remission (CR) rates among all schemes were ASCT combined with CAR-T, chemotherapy combined with ADC, and immune modulators; The top three overall response rates (ORR) were chemotherapy combined with ADC, ASCT combined with CAR-T, and ASCT. The CAR-T regimen had a higher rate of severe neutropenia; The severe thrombocytopenia rate of ASCT regimen was relatively high; There was no significant difference in the incidence of SAEs among the other options. ConclusionASCT combined with CAR-T and chemotherapy combined with ADC have the best therapeutic effects on r/r-DLBCL. However, the specific protocol to be adopted requires clinical doctors to combine actual conditions, comprehensively consider the efficacy and side effects, and develop personalized treatment strategies for r/r-DLBCL patients.

  • Pharmacoeconomic evaluation model for relapsed or refractory B-cell acute lymphoblastic leukemia therapies: a systematic review

    Objective To systematically review the pharmacoeconomic evaluation related to relapsed or refractory B-cell acute lymphoblastic leukemia (r/r B-ALL), and to summarize its model structure, parameter inclusion and other methodological parts for future r/r B-ALL-related interventions, and to provide references for conducting pharmacoeconomic evaluations. Methods PubMed, EMbase, The Cochrane Library, CNKI and WanFang Data databases were electronically searched to collect relevant literature on the pharmacoeconomic evaluation model of r/r B-ALL from inception to August 6th, 2021. Two reviewers independently screened literature, extracted data, and assessed the quality of the included studies. The data on the model structure, methods, and parameter inclusion were then summarized. Results A total of 10 studies using different modeling methods were included. Due to the lack of head-to-head trials, most of the efficacy parameters for the intervention and control groups were derived from different clinical trials and compared indirectly. All studies used quality-adjusted life years (QALYs) as output indicators, and some used life years (LYs) as output indicators and reported the incremental cost effectiveness ratio (ICER). All studies measured the cost of treatment and hematopoietic stem cell transplantation; a few studies also conducted subgroup analysis. Conclusion The number of studies on the economic evaluation of r/r B-ALL is relatively small, and there are large differences in model types, health status, and parameter inclusion. It is suggested that researchers should guarantee the integrity of the report format and normative according to available data choice drug economics evaluation model and establish the reasonable hypothesis under the condition of the patient population heterogeneity uncertainty, perform subgroup analysis especially on the subgroup which did not receive salvage therapy. In the absence of head-to-head clinical trials, appropriate indirect comparison methods are adopted according to the data obtained to reduce methodological differences and improve the quality of relevant pharmacoeconomic research in China.

  • Evidence-Based Treatment for Newly Diagnosed Diffuse Large-B-cell Lymphoma in an Elderly Patient

    Objective Methods of evidence-based medicine were used to make an individualized treatment plan concerning newly diagnosed diffuse large-B-cell lymphoma in elderly patients. Methods After clinical problems were put forward, evidence was collected from MEDLINE (Jan. 1990 to Dec. 2004) and http://sumsearch.uthscsa.edu/searchform4.htm. Subject words were: NHL; aggressive non-Hodgkin’s lymphoma; diffuse large-B-cell lymphoma; chemotherapy; CHOP; rituximab; RCT; economic evaluation; older patient. Results A total of 11 randomized controlled trials and 8 systematic reviews about chemotherapy regimen, and 1 systematic review about economic evaluation were identified. A rational treatment plan was made upon a critical evaluation of the data. After 5 months follow-up, the plan was proved optimal. Conclusions The treatment effectiveness in newly diagnosed diffuse large-B-cell lymphoma in the elderly has been improved by an individual treatment plan according to evidence-based methods.

  • 原发性纵隔大B细胞淋巴瘤治疗及研究新进展

    原发性纵隔大B细胞淋巴瘤(PMBL)是一种非霍奇金淋巴瘤的独特亚型,好发于青年女性,起源于胸腺髓质B细胞,主要表现为前上纵隔巨大肿块,患者症状与肿瘤的胸腔内浸润和压迫邻近器官有关。病理学表现为中等到大体积的肿瘤细胞弥漫增生,肿瘤细胞周围常有不同程度的纤维化和(或)硬化。PMBL表达多重成熟B细胞抗原和B细胞转录因子,但存在缺陷的免疫球蛋白产生。细胞遗传学涉及JAK2基因和c-REL基因的扩增。由于缺乏前瞻性的随机临床试验,目前尚未见PMBL患者治疗的最佳方案。推荐以蒽环类药物为基础的方案化学治疗(化疗),化疗结束后正电子发射计算机断层显像-CT评估是否辅助放射治疗(放疗)。推荐使用剂量调整后的依托泊苷+多柔比星+环磷酰胺+长春新碱+泼尼松+利妥昔单抗(DA-EPOCH-R)方案或利妥昔单抗+环磷酰胺+多柔比星+长春新碱+泼尼松+异环磷酰胺+卡铂+依托泊苷(RCHOP-ICE)方案化疗,可减少巩固放疗及其带来的远期副反应。患者预后与2个或以上的结外病变以及所接受的初始治疗关系密切。现就PMBL的最新治疗进展加以综述。
