目的探讨抗血管内皮细胞抗体(AECA)检测在川崎病(KD)早期诊断及体液免疫状况方面的临床意义。方法检测58例KD急性期患儿和43例对照组(其中普通发热对照23例,健康对照20例)儿童的血清AECA-IgG、免疫球蛋白IgG、IgA、IgM和补体C3、C4,计算各组AECA的阳性率,进而分别比较AECA阳性KD组、AECA阴性KD组与对照组的上述指标的浓度差异。结果①KD患儿AECA—IgG的阳性率为39.7%,明显高于健康对照组的5.0%(P〈0.01),也高于发热对照组的17.4%,但无统计学差异(P〉0.05);②AECA阳性组与AECA阴性组IgG、IgM、IgA、C3浓度均分别明显高于发热对照组和正常对照组(P〈0.05),C4水平只有AECA阳性组明显高于发热对照组和健康对照组(P〈0.05),但AECA阳性组与阴性组间上述指标差异无统计学意义(P〉0.05)。结论血清抗内皮细胞抗体在川崎病患儿中有较高的阳性率,具有一定的早期辅助诊断价值。川崎病急性期存在着明显的体液免疫异常,IgA介导的体液免疫可能在其中扮演着重要角色。 相似文献

Behçet's disease (BD) is a multisystem disorder with oral and genital ulcers, mucocutaneous, ocular, joint, vascular and central nervous system involvement. In this study, the peripheral T cell repertoire was analysed in patients with BD with MoAbs against T cell receptor (TCR) Vβ gene products in CD4+ and CD8+ T cell compartments, and these were compared with rheumatoid arthritis (RA) patients and healthy controls (HC). In the CD4+ T cell compartment, oligoclonal TCR Vβ expression was observed in 56% of BD (10/18), 71% of RA (5/7) patients and 21% (3/14) of HC. In the CD8+ T cell group 50% of BD (9/18), 57% of RA patients and 28% of HC (4/14) had an oligoclonal TCR repertoire. An increase of TCR Vβ5.1 subset was observed in five BD patients among CD8+ T cells. Other elevations of TCR Vβ subsets were heterogeneously distributed with one to three different Vβ subsets. Our results suggest an antigen-driven oligoclonal increase of T cells in BD. There was no overall increase in any Vβ group to suggest a superantigen effect. Analysis of the responsible antigens causing the increase in T cell subsets may give insights into the aetiopathogenesis of BD and immunomodulation of these T cells may lead to new treatments. 相似文献

Behcet's disease (BD) is a systemic inflammatory disease with a still unclear pathogenesis. Although several inflammatory molecules have been studied, current biomarkers are largely insensitive in BD and unable to predict disease progression and response to treatment. Our primary aim was to explore serum levels of soluble CD40 L (sCD40L), soluble intracellular adhesion molecule (sICAM‐1), monocyte chemoattractant protein‐1 (MCP‐1), myeloperoxidase (MPO), leptin, resistin, osteoprotegerin (OPG), soluble type 1 tumour necrosis factor receptor (sTNFR), interleukin (IL)?6 and serum amyloid A (SAA) serum concentration in a cohort of 27 BD patients. The secondary aim was to evaluate potential correlations between the putative circulating biomarkers, demographic profile of patients, the status of disease activity, the specific organ involvement at the time of sample collection and different therapeutic regimens. Serum concentrations of sTNFR (P = 0·008), leptin (P = 0·0011), sCD40L (P < 0·0001) and IL‐6 (P = 0·0154) were significantly higher in BD patients than in HC, while no difference was found in MCP‐1, MPO and resistin serum levels. Moreover, we observed significantly higher sTNFR serum concentrations in BD patients presenting inactive disease than HC (P = 0·0108). A correlation between sTNFR and age was also found, with higher levels in patients over 40 years than HC (P = 0·0329). Although further research is warranted to elucidate the role of circulating biomarkers, some of that may contribute to the understanding of the physiopathology processes underlying BD activity and damage as well as to provide useful tools for prognostic purposes and a personalized treatment approach. 相似文献

The mechanisms of adverse reactions to foods in the gastrointestinal tract are poorly understood. Previous studies of other atopic diseases and animal models suggest that adhesion molecules and mucosal lymphocytes may be implicated in the pathogenesis of food allergy (FA). The aim of our study was to investigate the expression of adhesion molecules and mucosal lymphocytes in duodena of patients with food allergies and of controls. Ten patients with FA to cereals (wheat, oats, and rye) or cow's milk and 9 control patients were included in the study. Quantitative analysis and immunohistochemical stainings for two pairs of adhesion molecules (intercellular adhesion molecule-1 (ICAM-1), lymphocyte function-associated antigen-1 (LFA-1), α4β7 integrin, and mucosal addressin cell adhesion molecule (MAdCAM-1) and lymphocyte markers on endoscopic duodenal biopsy specimens were performed. The villous structure and density of LFA-1-positive cells were normal in every biopsy specimen, but the patients had significantly more α4β7+ cells in the intraepithelial space (P = 0.01). The expression of ICAM-1 in the lamina propria of patients with FA was also substantially increased (P = 0.003); however, staining with MAdCAM showed no intergroup difference. Moreover, we found significantly increased CD4+ and HLA-DR+ cells in the lamina propria of patients, in comparison to the controls, P = 0.05 and P = 0.04, respectively. The densities of CD3, CD8, HLA-DP, T cell receptor αβ+ and γδ+ cells and IgA-, IgA1-, and IgA2-containing cells did not differ in the two groups studied. Our results suggest that the increased expression of ICAM-1 and α4β7 integrin may play an important role in the pathogenesis of food hypersensitivity and with the elevation of CD4- and HLA-DR-positive cells reflect a stage of inflammation in the structurally normal intestines. 相似文献

We enrolled 150 patients in a prospective multicenter study of children with acute myeloid leukemia undergoing hematopoietic stem cell transplantation (HSCT) to compare the detection of measurable residual disease (MRD) by a “difference from normal” flow cytometry (ΔN) approach with assessment of Wilms tumor 1 (WT1) gene expression without access to the diagnostic specimen. Prospective analysis of the specimens using this approach showed that 23% of patients screened for HSCT had detectable residual disease by ΔN (.04% to 53%). Of those patients who proceeded to transplant as being in morphologic remission, 10 had detectable disease (.04% to 14%) by ΔN. The disease-free survival of this group was 10% (0 to 35%) compared with 55% (46% to 64%, P < .001) for those without disease. The ΔN assay was validated using the post-HSCT specimen by sorting abnormal or suspicious cells to confirm recipient or donor origin by chimerism studies. All 15 patients who had confirmation of tumor detection relapsed, whereas the 2 patients with suspicious phenotype cells lacking this confirmation did not. The phenotype of the relapse specimen was then used retrospectively to assess the pre-HSCT specimen, allowing identification of additional samples with low levels of MRD involvement that were previously undetected. Quantitative assessment of WT1 gene expression was not predictive of relapse or other outcomes in either pre- or post-transplant specimens. MRD detected by ΔN was highly specific, but did not identify most relapsing patients. The application of the assay was limited by poor quality among one-third of the specimens and lack of a diagnostic phenotype for comparison. 相似文献
