BACKGROUND: Atherosclerosis is an inflammatory disease. Monocyte chemoattractant protein-1 (MCP-1) is an essential chemokine responsible for the recruitment of monocytes to inflammatory lesions in the vasculature, an initial step of atherosclerosis. Since serum levels of MCP-1 are higher in patients with type 2 diabetes, inhibition of MCP-1 may be a novel therapeutic target for prevention of accelerated atherosclerosis in diabetes. However, little is known about the regulation and determinants of serum MCP-1 levels in patients with diabetes. In this study, we examined the determinants of serum MCP-1 levels in type 2 diabetic patients. METHODS: Eighty-six consecutive outpatients with type 2 diabetes (36 male and 50 female; mean age 68.4+/-9.6) underwent a complete history and physical examination, determination of blood chemistries, MCP-1, tumour necrosis factor-alpha, adiponectin, advanced glycation end products (AGEs), and soluble form of receptor for AGEs (sRAGE). We examined the association between MCP-1 levels and those in anthropometric, metabolic and inflammatory variables in these subjects. RESULTS: Univariate regression analysis showed that serum levels of MCP-1 were positively associated with AGEs (r=0.386, p<0.001) and sRAGE (r=0.315, p<0.001). After adjusting for age and sex, AGEs (p<0.001) and sRAGE (p<0.05) still remained significant. CONCLUSION: The results demonstrate for the first time that circulating levels of AGEs and sRAGE are independent determinants of serum MCP-1 levels in patients with type 2 diabetes. Our present observations suggest the AGEs-RAGE system may be mainly involved in the elevation of MCP-1 in type 2 diabetic patients. 相似文献

During the influenza season, outbreaks of influenza may occur in the pediatric wards due to spread from the patients hospitalized with influenza, or from those hospitalized during the latency period and develop influenza afterwards. Post-exposure prophylaxis with neuraminidase inhibitors has been reported to be effective in preventing outbreaks among household members and nursing home residents. However, for nosocomial spread, its effectiveness and possible adverse effects are to be determined. During the 2002/2003 influenza season, we experienced a total of 3 nosocomial outbreaks of influenza in the pediatric wards in two hospitals in the Kanto district, Japan. Since the number of contacts who developed influenza had been increasing despite the isolation precaution implemented, post-exposure prophylaxis with oseltamivir (2 mg/kg/dose, maximum 75 mg/dose, once a day for 7-10 days) was implemented with a permission from the parents to terminate the outbreaks. In the outbreaks (one with influenza A, two with influenza B), a total of 29 inpatients had contact with influenza patients: among those 29, 13 were given post-exposure prophylaxis, 16 were not. Out of 16 patients who did not receive post-exposure prophylaxis, 11 (69%) developed influenza: out of 13 with post-exposure prophylaxis, none developed influenza. Those patients who developed influenza were given oseltamivir (2 mg/kg/dose, maximum 75 mg/dose, twice a day for 5 days) and accommodated in a private room or a room with other patients with influenza of the same type. No significant adverse effects due to oseltamivir were observed among those who were enrolled in this study. 相似文献

The aim of this study was to investigate the contribution of gene polymorphisms, in combination with habitual caffeine consumption, to the effect of caffeine intake on hemodynamic and psychoactive parameters. A double-blind, prospective study was conducted with 201 healthy volunteers randomly allocated 2:1 to the caffeinated group (150 mL decaffeinated coffee with additional 200 mg caffeine) or decaffeinated group (150 mL decaffeinated coffee). We measured the changes in blood pressure (BP) and calculation speed upon coffee intake, stratifying with gene polymorphisms, e.g., those in adenosine A2A receptor (ADORA2A) and cytochrome P450 (CYP) 1A2, and daily caffeine consumption (≤90 mg/day and >90 mg/day). Overall, caffeine intake independently increased BP and calculation speed (p-values < 0.05), irrespective of the polymorphisms. In stratified analysis, a statistical significance within the caffeinated group was observed for the change in systolic BP in the stratum of CYP1A2 polymorphism with daily caffeine consumption ≤90 mg/day: change in systolic BP in the CYP1A2 rs762551 CC group (mean ± SD = 11.8 ± 5.9) was higher than that in the AA/CA group (4.1 ± 5.5). Gene polymorphisms may limitedly modify the effect of caffeine intake on hemodynamic parameters in combination with habitual caffeine consumption. 相似文献

Narrowband ultraviolet B phototherapy (NB-UVB) is a therapeutic alternative for haematopoietic stem cell transplantation-related skin graft-versus-host disease (GVHD). The beneficial effects of this intervention may be induced by direct irradiation of inflammatory cells in the skin; however, the putative involvement of indirect effects on systemic immunity has not been elucidated. To address this issue, 11 acute skin GVHD patients refractory to standard corticosteroid treatment and with no gut/liver involvement were treated with NB-UVB irradiation. The median number of treatments was 10 times, with a mean cumulative exposure of 6.36 J/cm2. No other immunosuppressive therapy was initiated during irradiation. Eight patients achieved an objective complete response, two had a partial response, and one showed no change. None of the patients experienced progressive skin GVHD or newly diagnosed gut/liver GVHD. NB-UVB was well tolerated, with no patients discontinuing irradiation due to toxicity. We additionally demonstrated by flow cytometry that NB-UVB irradiation induces the increment of the proportion of regulatory T cell (Tregs) in patients’ peripheral blood. These results suggest that NB-UVB may exert beneficial effects on steroid-refractory skin GVHD through the expansion of Tregs. 相似文献

We report a case of active infective endocarditis in a young adult, affecting the anterior and posterior leaflets extensively. The patient underwent a mitral valve repair with extended sliding repair on the posterior leaflet and reconstruction using an autologous pericardial patch supported by an artificial chord on the anterior leaflet. Although we finally needed commissure closing for successful repair, we aggressively achieved a repair-oriented strategy using several techniques in a young patient who may have required mitral valve replacement. 相似文献
