Increased serum concentrations of soluble intercellular adhesion molecule-1 (sICAM-1), soluble endothelial leucocyte adhesion molecule-1 (sELAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) were detected in Danish malaria patients infected with sequestering Plasmodium falciparum or non-sequestering P. vivax parasites, as well as in patients with sepsis or meningitis. Levels of soluble adhesion molecules remained elevated in the P. falciparum patients for several weeks after initiation of treatment. Plasma concentrations of sICAM-1, sVCAM-1 and sELAM-1 were higher in Gambian children with severe P. falciparum malaria than in children with mild malaria. Plasma levels of sVCAM-1 and sELAM-1 were significantly correlated. Plasma levels of sELAM-1 and sVCAM-1 may reflect endothelial inflammatory reactions and these reactions may be harmful for humans infected with malaria parasites.  相似文献

Objective   To investigate if Chlamydia pneumoniae and/or Helicobacter pylori seropositivity is associated with elevated levels of soluble endothelial cell adhesion molecules (sCAMs) as markers of atherosclerotic activity.
Methods   Immunoglobulin A (IgA) and IgG antibodies to the two bacteria, soluble intercellular cell adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1) and E-selectin were measured in coronary heart disease (CHD) patients ( n  = 193) and age- and sex-matched controls ( n  = 193). Two different serological methods were used for the detection of Chlamydia antibodies: Labsystems microimmunofluorescence to detect species-specific C. pneumoniae antibodies and Medac's recombinant enzyme-linked immunosorbent assay to detect genus-specific lipopolysaccharide antibodies.
Results   The concentrations of sICAM-1 and E-selectin were higher in CHD patients with positive vs. negative Chlamydia lipopolysaccharide IgA ( P  = 0.044 for both). H. pylori antibodies alone did not predict raised levels of sCAMs, but in CHD patients sICAM-1 was increased with IgA seropositivity to both bacteria compared to double seronegativity ( P  = 0.034). Concentrations of sVCAM-1 were elevated in CHD patients with double IgA seropositivity compared to those with Chlamydia lipopolysaccharide IgA seropositivity alone ( P  = 0.018).
Conclusion   Our results may indicate that C. pneumoniae contributes to increased inflammation in CHD, and that this contribution is even more pronounced when present in combination with H. pylori IgA antibodies.  相似文献

BACKGROUND AND PURPOSE: Henoch-Sch?nlein purpura (HSP) is a small vessel vasculitis. Soluble adhesion molecules play a very important role in the immuno-inflammatory reaction of damaged vascular tissues. This study investigated the prognostic and diagnostic potential of soluble intracellular adhesion molecule-1 (sICAM-1) and vascular cell adhesion molecule-1 (sVCAM-1) in HSP. METHODS: Serum levels of sICAM-1 and sVCAM-1 were studied in 26 children with HSP. Paired blood samples (during acute and convalescent stages) were collected from 17 of the children and assayed by enzyme-linked immunosorbent assay. Correlations with clinical manifestations were examined. Seventeen healthy children served as controls. RESULTS: Both sICAM-1 and sVCAM-1 were significantly elevated at the acute stage compared with the remission stage of HSP patients versus controls (p=0.006 and p=0.0173, respectively). CONCLUSIONS: Although the levels of sICAM-1 and sVCAM-1 were not correlated with the severity of clinical manifestations in HSP, these soluble adhesion molecules may serve as diagnostic markers.  相似文献

Fifty-nine children with acute Kawasaki disease (KD), a childhood vasculitis, were compared with 35 children with fever due to infection and 48 healthy children. Levels of soluble E-selectin (sE-selectin), soluble intercellular adhesion molecule-1 (sICAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) in the healthy children were double those found in adults. All three soluble cell adhesion molecules and von Willebrand factor (vWF) were higher in the children with KD than in the healthy children, but only sE-selectin, a marker for activated endothelial cells, and sICAM-1 were higher than in the febrile children. The high levels of vWF in KD appear to reflect the prominent acute-phase reaction. This information can help us to understand further the complex interactions between cytokines, circulating inflammatory cells and the vascular endothelium, and may lead to new therapeutic avenues in KD and other inflammatory diseases and vasculitides.  相似文献

Soluble vascular cell adhesion molecule (sVCAM-1) and soluble intercellular adhesion molecule (sICAM-1) are adhesion molecules that are detectable in the serum of patients with cancer, cardiovascular diseases (CVD), and type 2 diabetes. This report describes enzyme-linked immunosorbent assays (ELISAs) on microplates for sVCAM-1 and sICAM-1. The ELISAs have the sandwich test format; polyclonal antibodies are coated on microwells and a one-step procedure is used in which the serum specimen and detecting antibody are added simultaneously to an antibody-coated well. These assays both use HRP-conjugated sheep anti-mouse-IgG to generate the color for quantification. Sensitivities for detecting sVCAM-1 and sICAM-1 are 49 and 40 ng/ml, respectively. Coefficients of variation for within-day and day-to-day replicate analyses are <10%. Results by these in-house ELISAs for serum sVCAM-1 and sICAM-1 compared well with those obtained with commercial kits from R&D Systems, Inc. (correlation coefficients = 0.98 and 0.99 for sVCAM-1 and sICAM-1, respectively). Reference values for serum sVCAM-1 and sICAM-1 levels were measured in 369 apparently healthy Chinese adults, age 30 to 79 yr. There was no significant effect of gender on the reference values for sVCAM-1 or sICAM-1. Serum sVCAM-1 levels (mean +/- SD) were higher in subjects 60 yr old (625 +/- 126 ng/ml), compared to those <60 yr old (525 +/- 110 ng/ml) (p <0.001). Age did not significantly affect the reference values for serum sICAM-1 levels (mean +/- SD, 249 +/- 86 ng/ml). The authors believe that these simple, inexpensive ELISAs will be useful for assessing the risks for development of cancer, CVD, and type 2 diabetes.  相似文献

Active SLE is characterized by immune deposits and subsequent vascular inflammation in many organs. Expression and up-regulation of adhesion molecules is basic to migration of inflammatory cells into the tissues. Recently, soluble isoforms of these molecules have been described which might be an expression of their up-regulation in the tissues and, as such, of disease activity. The purpose of this study was to evaluate whether changes in levels of soluble adhesion molecules reflect disease activity. We analysed serial sera in a 6-month period preceding 22 consecutive exacerbations of SLE for levels of soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble intercellular adhesion molecule-1 (sICAM-1), and sE-selectin. Levels were related to clinical disease activity (SLEDAI), and levels of anti-dsDNA and complement. At the time of maximal disease activity, levels of sVCAM-1 in patients with SLE were higher than those in controls (P < 0.0001), levels in patients with renal involvement being higher than in those without (P < 0.02). Levels of sVCAM-1 correlated with SLEDAI scores (P < 0.05) and, inversely, with levels of C3 (P = 0.01). In addition, in the presence of anti-dsDNA, levels of sVCAM-1 tended to correlate with levels of these autoantibodies (P < 0.1). Levels of sICAM-1 were normal and sE-selectin levels even decreased compared with controls. Levels of sVCAM-1 were higher at the moment of relapse (P = 0.001) than at 6 months before this time point. This rise correlated with the rise in SLEDAI score (P < 0.02). Levels of sICAM-1 and sE-selectin did not rise, and remained in the normal range in all exacerbations studied. In conclusion, in contrast to sICAM-1 and sE-selectin, levels of sVCAM-1 are increased, rise parallel to disease activity during exacerbations in SLE, and are associated with decreasing levels of complement factors. This favours the hypothesis of immune deposit formation, activation of the complement cascade and activation of endothelial cells. Concurrent up-regulation of vascular adhesion molecules may thus result in transmigration of activated inflammatory cells inducing tissue damage.  相似文献

Maternal serum levels of VCAM-1, ICAM-1 and E-selectin in preeclampsia   总被引:1,自引:0,他引:1  
Endothelial dysfunction is thought to be a central pathogenic feature in preeclampsia on the basis of elevated adhesion molecules. The aim of the present study was to compare the levels of soluble vascular cell adhesion molecule-1 (sVCAM-1), intercellular adhesion molecule-1 (sICAM-1) and E-selectin (sE-selectin) in sera of normal and preeclamptic pregnancies. We studied the serum levels of sVCAM-1, sICAM-1 and sE-selectin in normal pregnant women (n=63), mild preeclampsia (n=33) and severe preeclampsia (n=82). Concentrations of soluble adhesion molecules were determined with enzyme-linked immunoassay (ELISA). Serum concentrations of sVCAM-1 were significantly higher in both mild (p=0.004) and severe preeclampsia (p=0.000) than normal pregnancy. There were also significant differences in sVCAM- 1 levels between mild and severe preeclampsia (p=0.002). sICAM-1 levels of severe preeclampsia were statistically different from those of normal pregnancy (p=0.038). Levels of sE-selectin were elevated in both mild (p=0.011) and severe preeclampsia (p=0.000) compared to normal pregnancy, but no statistical difference between the mild and severe preeclampsia (p=0.345). These results suggest that all three soluble adhesion molecules are increased in severe preeclampsia, and sVCAM-1 among them may be useful in predicting the severity of preeclampsia.  相似文献

INTRODUCTION: The purpose of this study was to determine the effect of repeated infusions of infliximab, a chimeric anti-tumor necrosis factor (anti-TNF)-alpha antibody, on the levels of soluble adhesion molecules and vascular endothelial growth factor (VEGF) in patients with active rheumatoid arthritis (RA). MATERIALS AND METHODS: The treatment design consisted of 9 infusions of infliximab (3 mg/kg) at weeks 0, 2, 6, and every 8 weeks thereafter. All patients had been receiving methotrexate (MTX; 7.5-20 mg/week). Serum levels of soluble intercellular adhesion molecule (sICAM)-1, vascular cell adhesion molecule (sVCAM)-1, E-selectin (sE-selectin), and VEGF were measured by ELISA at weeks 0, 2, 6, 14, and 38 prior to infusion, and at week 62. RESULTS: A remarkable decrease in serum sICAM-1 (p<0.001), sVCAM-1 (p<0.01), sE-selectin (p<0.01) and VEGF (p<0.001) levels was observed in RA patients after the initial dose of infliximab. The second administration of the drug was followed by an even more significant suppression of serum sICAM-1, sVCAM-1, sE-selectin, and VEGF (p<0.001 in all cases). Further infliximab infusions also significantly reduced serum soluble adhesion molecules and VEGF concentrations, although these were less effective. Infliximab treatment induced a significant decrease in the number of monocytes observed until the end of the study. CONCLUSIONS: Our study, besides a rapid suppression of disease activity, showed that serum soluble adhesion molecules and VEGF concentrations are down-regulated following anti-TNF-alpha antibody therapy combined with MTX. Repeated doses of infliximab sustained the reductions in the soluble adhesion molecules and VEGF concentrations, although they were less effective than the first and second infusions of infliximab.  相似文献

BACKGROUND: Adhesion molecules are expressed on vascular endothelium and on immune and inflammatory cells. Recently increased levels of adhesion molecules have been shown in patients with rheumatic mitral stenosis. This study examined the serum levels of the adhesion molecules intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), and E-selectin in patients with rheumatic mitral stenosis and the effects of percutaneous mitral balloon valvuloplasty (PMBV) on these adhesion molecules. MATERIALS AND METHODS: Thirty five patients (3 men, 32 women, mean age 39+/-5 years) with severe rheumatic mitral stenosis who underwent percutaneous balloon mitral valvuloplasty, and 35 age and sex matched healthy control subjects were included in the study. Serum levels of ICAM-1, VCAM-1, and E-selectin were measured in all patients who underwent PMBV and in all control subjects. Blood samples were taken for measurement of adhesion molecules immediately before and 24 h after the mitral balloon valvuloplasty. RESULTS: The plasma levels of soluble adhesion molecules E-selectin, ICAM-1 and VCAM-1 were significantly elevated in patients with mitral stenosis compared to control subjects: E-selectin, 97+/-59 vs. 45+/-24 ng/ml (P=.001), sICAM-1, 874+/-301 ng/ml vs. 238+/-82 ng/ml (P<.0001); sVCAM-1, 3056+/-763 ng/ml vs. 985+/-298 ng/ml (P<.0001). Plasma levels of VCAM-1 significantly increased 24 h after the valvuloplasty procedure (3056+/-763 ng/ml vs. 3570+/-1225 ng/ml P=.013). Plasma levels of E-selectin showed a significant decrease after PMBV (97+/-59 vs. 70+/-58 ng/ml, P=.043) and plasma levels of ICAM-1 did not show any change after PMBV (874+/-301 vs. 944+/-377 ng/ml, P=.356). CONCLUSION: Cellular adhesion molecules, sICAM-1, E-selectin, sVCAM-1 have shown changes in different directions in response to PMBV. These results necessitate further studies to clarify the mechanism underlying the association between adhesion molecules and PMBV as well as rheumatic mitral stenosis.  相似文献
