Abstract
Diabetes mellitus is a major healthcare problem. It is not only characterized by hyperglycemia and chronic complications, but in longer lasting diabetes and a longer living population, it is also associated with accelerated arterial ageing, which importantly contributes to cardiovascular complications. The accelerated arterial ageing in patients with diabetes should be considered separately from arterial ageing in patients without diabetes. Basic and clinical research have allowed better insight into the mechanisms of arterial ageing. In a simplified mechanistic way, it could be considered that the three tightly connected cornerstone characteristics of arterial ageing in patients with diabetes are: phenotypic presentation as endothelial dysfunction and arterial stiffness, and the underlying basic ageing-facilitating mechanism represented as the impaired expression of genetic longevity pathways. Currently, specific drugs for preventing/treating arterial ageing are not available. Therefore, we aimed to review the capacity of available drugs, particularly antidiabetic drugs, to interfere with the arterial ageing process. In the near future, these characteristics could help to guide therapy in patients with diabetes. Overall, it appears that arterial ageing could become a new target in diabetes. The expanding knowledge regarding the capability of antidiabetic drugs and other available drugs to inhibit/delay arterial aging is therefore essential.

Abstract
Brown adipose tissue (BAT), an organ that burns energy through uncoupling thermogenesis, is a promising therapeutic target for obesity. However, there are still no safe anti-obesity drugs that target BAT in the market. In the current study, we performed large scale screening of 636 compounds which were approved by Food and Drug Administration (FDA) to find drugs that could significantly increase uncoupling protein 1 (UCP1) mRNA expression by real-time PCR. Among those UCP1 activators, most of them were antibiotics or carcinogenic compounds. We paid particular attention to fluvastatin sodium (FS), because as an inhibitor of the cellular hydroxymethyl glutaryl coenzyme A (HMG-CoA) reductase, FS has already been approved for treatment of hypercholesteremia. We found that in the cellular levels, FS treatment significantly increased UCP1 expression and BAT activity in human brown adipocytes. Consistently, the expression of oxidative phosphorylation-related genes was significantly increased upon FS treatment without differences in adipogenic gene expression. Furthermore, FS treatment resisted to high-fat diet (HFD)-induced body weight gain by activating BAT in the mice model. In addition, administration of FS significantly increased energy expenditure, improved glucose homeostasis and ameliorated hepatic steatosis. Furthermore, we reveal that FS induced browning in subcutaneous white adipose tissue (sWAT) known to have a beneficial effect on energy metabolism. Taken together, our results clearly demonstrate that as an effective BAT activator, FS may have great potential for treatment of obesity and related metabolic disorders.

Abstract
Cardiovascular disease is the leading cause of morbidity and mortality in subjects with type 2 diabetes mellitus. Increased aortic stiffness, assessed with the carotid-femoral pulse wave velocity, is an independent risk factor for cardiovascular disease. Statins reduce effectively cardiovascular disease and mortality in high-risk patients. The aim of this prospective non-randomized, observational study was to examine the impact of treatment with either 10 mg atorvastatin plus diet or diet alone on carotid-femoral pulse wave velocity in subjects with type 2 diabetes mellitus and dyslipidaemia. A total of 79 subjects with type 2 diabetes mellitus and dyslipidaemia were included; 46 subjects were treated with atorvastatin 10 mg daily plus diet and 33 were managed by diet alone for 12 months. Carotid-femoral pulse wave velocity and carotid-radial pulse wave velocity were measured using applanation tonometry. In the atorvastatin-treated group, carotid-femoral pulse wave velocity reduced significantly during the study and there was a trend for reduction in the carotid-radial pulse wave velocity. Total cholesterol, low-density lipoprotein cholesterol, triglycerides and C-reactive protein were reduced only in the atorvastatin-treated participants. No significant changes were found in body mass index, blood pressure, heart rate, diabetes control and high-density lipoprotein cholesterol in either study group. Treatment with low-dose atorvastatin for 12 months improves carotid-femoral pulse wave velocity in subjects with type 2 diabetes mellitus and dyslipidaemia.

Abstract
In Diabetes Mellitus (DM), hyperglycaemia and insulin resistance progressively lead to both
microvascular and macrovascular complications. Whereas the incidence of microvascular complications
is closely related to tight glycaemic control, this does not apply to macrovascular complications. Hyperglycaemia
influences many interweaving molecular pathways that initially lead to increased oxidative
stress, increased inflammation and endothelial dysfunction. The latter represents the initial in both types
of vascular complications; it represents the “obligatory damage” in microvascular complications development
and only “introductory damage” in macrovascular complications development. Other risk factors,
such as arterial hypertension and dyslipidaemia, also play an important role in the progression of
macrovascular complications. All these effects accumulate and lead to functional and structural arterial
wall damage. In the end, all factors combined lead to the promotion of atherosclerosis and consequently
major adverse cardiovascular events. If we accept the pivotal role of vascular wall impairment in the
pathogenesis and progression of microvascular and macrovascular complications, treatment focused
directly on the arterial wall should be one of the priorities in prevention of vascular complications in
patients with DM. In this review, an innovative approach aimed at improving arterial wall dysfunction is
described, which may show efficacy in clinical studies. In addition, the potential protective effects of
current treatment approaches targeting the arterial wall are summarised.

Abstract
Background We tested the concept of improving arterial wall characteristics by treatment with a very low-dose combination of fluvastatin and valsartan (low-flu/val) in stable, post-myocardial infarction (MI) patients. Material/Methods We enrolled 36 post-MI middle-aged males in the treatment (n=20) or control (n=16) group receiving low-flu/val (10 mg/20 mg) or placebo, respectively. The parameters of endothelial function (flow-mediated dilatation (FMD), reactive hyperemia index), and arterial stiffness (carotid-femoral pulse wave velocity (cf-PWV), local carotid PWV, and beta stiffness coefficient) were measured before and after 30 days of therapy, and 10 weeks later. Results Treatment with low-flu/val improved FMD from 3.1±1.3% to 4.8±1.5% (p<0.001; by 54.8%) and cf-PWV from 7.8±1.1 to 6.7±1.5 m/s (p<0.01; by 14.1%) without affecting either lipids or blood pressure. In the treatment group, FMD and/or cf-PWV significantly improved in 17 patients, but the improvements did not correlate. The benefits obtained were still detectable 10 weeks after complete treatment cessation. No changes were obtained in the control group. No other vascular parameters changed. Conclusions Low-flu/val added “on top of” optimal therapy substantially improves endothelial function and arterial stiffness in post-MI patients. Since these improved parameters are well-known predictors of future coronary events, such treatment could decrease cardiovascular risk. Further studies are therefore warranted.

Abstract
BACKGROUND The largest population that suffers from cardiovascular events are subjects at moderate cardiovascular risk. However, no effective and safe preventive treatment is available for this population. We investigated whether their arterial wall phenotype could be turned to a lower risk direction by low-dose fluvastatin/valsartan combination (low-flu/val). METHODS Twenty males at moderate cardiovascular risk (as classified by SCORE) were blindly randomized into the intervention group (N.=10, low-flu/val: 10 mg/20 mg) or control group (N.=10, placebo). At inclusion and after 30 days of treatment, brachial flow-mediated dilatation (FMD), β-stiffness coefficient, carotid pulse wave velocity (c-PWV), carotid-femoral PWV, Reactive Hyperemia Index, high-sensitivity C-reactive protein (hs-CRP), interleukin 6, vascular cell adhesion molecule 1, total antioxidant status and expression of several protective genes (SIRT1, mTOR, NF-κB1, NFE2L2, PRKAA1) were followed. RESULTS Treatment resulted in improved FMD (from 3% to 4.2%, P=0.008), c-PWV (from 6.7 to 6.2 m/s, P=0.006), hs-CRP (from 5.39 to 3.35 mg/L, P=0.041) and SIRT1 expression (3.34-fold difference, P=0.047). No other vascular, inflammation and genetic parameters changed. The hs-CRP values after intervention correlated significantly with SIRT1 expression. The improved FMD persisted even 10 weeks after treatment discontinuation. The obtained changes were not followed by changes of lipids or blood pressure. Overall, the results revealed improvement in three different, although interrelated preventive arterial wall characteristics. CONCLUSIONS This pilot study revealed that intervention with low-flu/val importantly shifts the arterial wall phenotype in a lower risk direction. This improvement could be interpolated into clinical benefits that remain to be further studied.

Sub-therapeutic doses of fluvastatin and valsartan are more effective than therapeutic doses in providing beneficial cardiovascular pleiotropic effects in rats: A proof of concept study. Vascul Pharmacol 2017; 99:45-52. [PMID: 28951255 DOI: 10.1016/j.vph.2017.09.005] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2017] [Revised: 08/07/2017] [Accepted: 09/20/2017] [Indexed: 11/21/2022]
Abstract
BACKGROUND Statins and sartans can, in therapeutic doses, induce pleiotropic cardiovascular effects. Similar has recently been shown also for sub-therapeutic doses. We thus explored and compared the cardiovascular pleiotropic efficacy of sub-therapeutic vs. therapeutic doses. METHODS Wistar rats were randomly divided into 7 groups receiving fluvastatin, valsartan and their combination in sub-therapeutic and therapeutic doses, or saline. After 6weeks, the animals were euthanised, their hearts and thoracic aortas isolated, and blood samples taken. Endothelium-dependent relaxation of the thoracic aortae and ischaemic-reperfusion injury of the isolated hearts were assessed along with the related serum parameters and genes expression. RESULTS Fluvastatin and valsartan alone or in combination were significantly more effective in sub-therapeutic than therapeutic doses. The sub-therapeutic combination greatly increased thoracic aorta endothelium-dependent relaxation and maximally protected the isolated hearts against ischaemia-reperfusion injury and was thus most effective. Beneficial effects were accompanied by increased levels of nitric oxide (NO) and decreased levels of asymmetric dimethylarginine (ADMA) in the serum (again prominently induced by the sub-therapeutic combination). Furthermore, nitric oxide synthase 3 (NOS3) and endothelin receptor type A (EDNRA) genes expression increased, but only in both combination groups and without significant differences between them. In the therapeutic dose groups, fluvastatin and valsartan decreased cholesterol values and systolic blood pressure. CONCLUSION Sub-therapeutic doses of fluvastatin and valsartan are more effective in expressing cardiovascular pleiotropic effects than therapeutic doses of fluvastatin and/or valsartan. These results could be of significant clinical relevance.
