Different expression pattern of serum soluble intercellular adhesion molecules-1 and neutrophilic expression of CD18 in patients with diabetic retinopathy

AIM: To investigate the levels of serum soluble intercellular adhesion molecules-1 (sICAM-1) and neutrophilic expression of CD18 in patients with various stages of diabetic retinopathy and to determine their different expression pattern in the development of diabetic retinopathy(DR). METHODS: Levels of serum sICAM-1 and CD18 on the surface of neutrophile were measured in 41 DR patients, they were classified in three subgroups according to the stage of retinopathy as determined by fund's ophthalmoscopy; 10 control subjects were also studied. sICAM-1 were measured by enzyme-linked immunosorbent assay and CD18 by flow cytometry. RESULTS: The neutrophilic CD18 expression and serum sICAM-1 level were all significantly elevated in all diabetic subgroups compared to control subjects (P <0.01). The differences of CD18 and sICAM-1 among the diabetic subgroups were significant in CD18 but not in sICAM-1. The progression of retinopathy was associated with an increase both in CD18 and in sICAM-1 levels by simple correlation analysis (beta =0.74, P<0.001; beta =0.38, P<0.01, respectively). But stepwise multiple regression analysis revealed that only CD18 Was independent determinant of retinopathy (beta =1.04, P<0.01). CONCLUSION: Our results confirm the contribution of endothelial and neutrophilic activation in the development of DR as indicated by increased levels of CD18 and sICAM-1. However, a direct implication of CD18 and ICAM-1 in the progression of DR can be supported only in the CD18 but not ICAM-1. CD18 and ICAM-1 may play different role in the development of diabetic retinopathy.

Pre-diagnostic levels of adiponectin and soluble vascular cell adhesion molecule-1 are associated with colorectal cancer risk

AIM: To examine the relationships between pre-diagnostic biomarkers and colorectal cancer risk and assess their relevance in predictive models.METHODS: A nested case-control study was designed to include all first primary incident colorectal cancer cases diagnosed between inclusion in the SUpplémentation en VItamines et Minéraux AntioXydants cohort in 1994 and the end of follow-up in 2007. Cases (n = 50) were matched with two randomly selected controls (n = 100). Conditional logistic regression models were used to investigate the associations between pre-diagnostic levels of hs-CRP, adiponectin, leptin, soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble intercellular adhesion molecule-1, E-selectin, monocyte chemoattractant protein-1 and colorectal cancer risk. Area under the receiver operating curves (AUC) and relative integrated discrimination improvement (RIDI) statistics were used to assess the discriminatory potential of the models. RESULTS: Plasma adiponectin level was associated with decreased colorectal cancer risk (P for linear trend = 0.03). Quartiles of sVCAM-1 were associated with increased colorectal cancer risk (P for linear trend = 0.02). No association was observed with any of the other biomarkers. Compared to standard models with known risk factors, those including both adiponectin and sVCAM-1 had substantially improved performance for colorectal cancer risk prediction (P for AUC improvement = 0.01, RIDI = 26.5%). CONCLUSION: These results suggest that pre-diagnostic plasma adiponectin and sVCAM-1 levels are associated with decreased and increased colorectal cancer risk, respectively. These relationships must be confirmed in large validation studies.

Monocyte chemotactic protein-1 and soluble adhesion molecules as possible prognostic markers of the efficacy of antiviral treatment in chronic hepatitis C

AIM: To explain the role of Monocyte chemotactic protein-1 (MCP-1) and soluble adhesion molecules in chronic hepatitis C during the treatment of interferon alpha (IFNα) 2 b and ribavirin (RBV).METHODS: Concentrations of MCP-1, soluble adhesion molecules intercellular adhesion molecule-1 (sICAM-1), sPselectin, interleukin (IL) 6, and ILl0 in serum were estimated in the group of 40 patients with chronic hepatitis C treated with IFNalpha2 b and RBV in 0, 16, 32, 48 wk of the therapy.RESULTS: In chronic hepatitis C, before and during the treatment, the serum levels of MCP-1 and sP-selectin in responders were similar to those of healthy subjects. In nonresponders (NR), MCP-1 increased in the course of IFN(α+RBV treatment, differences were statistically significant as compared to responders. MCP-1 correlated statistically with the activity of periportal inflammation (r= 0.35, P<0.05) but not with staging of liver fibrosis, sICAM-1 positively correlated with inflammatory activity and fibrosis in NR. sP-selectin did not correlate with histological findings in the liver. The MCP-1 correlated with the soluble form of sP-selectin concentrations (r= 6, P<0.001) and with IL-10 level in NR (r = 0.4, P<0.05). There was no correlation observed between the concentration of MCP-1 and sICAM-1, IL-6 during the treatment.CONCLUSION: MCP-1 concentration may be a prognostic marker of the efficacy of IFN+RBV therapy in patients with chronic hepatitis C.

Circulating Adhesion Molecules in Patients with Keshan Disease and Their Relationship with Coxsackie B Virus Infection

This study determined the levels of serum soluble intercellular adhesion molecule-1 （sI-CAM-l） and soluble vascular cell adhesion molecular-1 （sVCAM-1） in patients with different types of Keshan disease （KD）, examined the relationship between Coxsackie B virus-specific IgM antibody （CBV-IgM） and slCAM-1 or sVCAM-1 in KD patients, and investigated the role of these adhesion molecules in the pathogenesis of KD and their clinical implications. The levels of serum slCAM-1, sVCAM-1 and CBV-IgM were measured by using enzyme-linked immunosorbent assay in 22 patients with chronic Keshan disease （CKD）, 27 with latent Keshan disease （LKD） and 28 healthy controis. The subjects in different groups were adjusted for sex and age. Echocardiography was adopted to determine left ventricular ejection fraction （LVEF） in 22 patients with CKD. The results showed that CKD patients had significantly higher levels of slCAM-1 and sVCAM-1 than LKD patients and healthy controls （P〈0.01 for all）. And there was significant difference in the levels of the 2 adhesion molecules between LKD patients and healthy controls （P〈0.05）. A negative correlation was found between LVEF and slCAM-1 or sVCAM-1 in CKD patients. The percentage of CBV-specific IgM positive individuals in KD patients was significantly higher than that of healthy controls. In CVB-specific IgM positive patients, the levels of serum slCAM-1 and sVCAM-1 were significantly greater than those in CBV-specific IgM negative counterpart. It was concluded that the increase in the levels of slCAM-1 and sVCAM-1 suggests the progression of inflammation in KD. slCAM-1 and sVCAM-1 can promote the development of myocardial pathology and lead to poor myocardial function. The increased serum slCAM-1 and sVCAM-1 in KD patients may be related to CBV infection.
