Menopause, but not age, is directly involved in augmented FPG levels in nondiabetic women.

Aim: Previous studies have been inconsistent results about the effects of statins on serum triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and high sensitivity C-reactive protein (hsCRP) levels. We therefore investigated the effects of pitavastatin on serum lipid profiles and hsCRP levels in patients with type 2 diabetes mellitus. Methods: The study population was 65 Japanese type 2 diabetic patients who had been administered 2 mg daily of pitavastatin and completed a 6-month follow-up. Serum lipids and hsCRP were measured before and after treatment for 1, 3, and 6 months. Results: Total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and TG had significantly reduced after 1 month and remained reduced for 6 months, while HDL-C levels had significantly increased after 1 month and remained at the higher level for 6 months. Baseline median levels of hsCRP were 0.49 mg/L and showed a significant reduction to 0.37 mg/L at 6 months' treatment (p 0.001). Six-month changes in hsCRP levels were not associated with those in TC, LDL-C, HDL-C or TG. Conclusion: Pitavastatin improved serum lipid profiles and reduced serum hsCRP levels in type 2 diabetic patients with relatively low inflammation. The effect on hsCRP was not related to the effects on serum lipid profiles.

The antiinflammatory action of glucocorticoids is mediated partly by the inhibition of the expression of several cytokines and adhesion molecules. Some activators for nuclear receptors other than the GR have also been shown to inhibit the expression of these inflammatory molecules, although their molecular mechanisms remain unidentified. We therefore examined the effects of the PPARalpha activator fenofibrate and the GR activator dexamethasone on TNFalpha-stimulated expression of IL-6 and vascular cell adhesion molecule-1 in vascular endothelial cells. Both fenofibrate and dexamethasone reduced TNFalpha-induced IL-6 production in human vascular endothelial cells, but only fenofibrate reduced TNFalpha-stimulated vascular cell adhesion molecule-1 expression in these cells. Transient transfection of bovine aortic endothelial cells with an IL-6 promoter construct or a vascular cell adhesion molecule-1 promoter construct revealed that fenofibrate inhibited TNFalpha-induced IL-6 promoter as well as vascular cell adhesion molecule-1 promoter activities, whereas dexamethasone inhibited only the former. EMSA demonstrated that both fenofibrate and dexamethasone reduced nuclear factor-kappaB binding to its recognition site on the IL-6 promoter, but only fenofibrate reduced such binding to the vascular cell adhesion molecule-1 promoter. Thus, down-regulation of nuclear factor-kappaB activity by PPARalpha occurs in both the IL-6 and vascular cell adhesion molecule-1 genes, whereas that by GR occurs only in the IL-6 gene in vascular endothelial cells. These results strongly suggest the existence of a target gene-specific mechanism for the nuclear receptor-mediated down-regulation of nuclear factor-kappaB activity.

Although reports of serious infections in clinical trials for rheumatoid arthritis (RA) with tocilizumab, anti-interleukin6 (IL-6) receptor antibody, have been relatively few, there is still some concern about infections. We report here two cases of patients who developed severe pneumonia during tocilizumab treatment for RA. Both patients initially presented with only minimal clinical symptoms and modest elevations in serum C-reactive protein. Tocilizumab might suppress the early inflammatory symptoms of pneumonia.

The present study demonstrates that DHEAS and IGF-I levels are associated with each other, independent of age, in women in middle adulthood.
