Abstract
BACKGROUND AND AIMS To evaluate the long-term effect of simultaneous treatment of hypertension and hypercholesterolemia with angiotensin-converting enzyme (ACE) inhibitors and statins on the incidence of major cardiovascular events (MACE) and other clinical outcomes. METHODS AND RESULTS We considered data from a subset of Brisighella Heart Study (BHS) participants who were consecutively evaluated in three epidemiological surveys between 2012 and 2020. We excluded normotensive subjects and individuals with a low calculated 10-year CVD risk, hypertensive patients treated with antihypertensive drugs different from ACE inhibitors and patients who changed antihypertensive medications during follow-up. The remaining participants were divided into four groups depending on whether they were treated with (I) perindopril ± amlodipine without statin treatment (N. 132), (II) perindopril ± amlodipine and atorvastatin (N. 132), (III) an ACE inhibitor other than perindopril ± a calcium-channel blocker without statin therapy (N. 133), (IV) an ACE inhibitor other than perindopril ± a calcium-channel blocker and statin therapy (N. 145). The long-term (8 years) effects of the different combined treatment were compared among the pre-defined groups. Over the follow-up period of 8 years, the proportion of subjects who developed MACE, type 2 diabetes mellitus and hyperuricemia, and the proportion of subjects needing for the intensification of antihypertensive treatment to improve blood pressure control were statistically different among the predefined groups (P < 0.05). CONCLUSION Combined treatment with ACE inhibitors and statins (especially atorvastatin) in hypertensive patients seems to significantly reduce the risk of developing CVD in comparison with treatment with ACE inhibitors alone.

Abstract
Abstract
Background
Conflicting data suggest that statins could cause hepatitis in certain group of patients, while improving prognosis in patients affected by some chronic liver diseases. Therefore, we aimed to quantify the potential protective role of statins on some main liver-related health outcomes in clinical studies on patients affected by hepatitis.
Methods
We applied fixed-effects or random-effects meta-analyses with inverse variance weighting to calculate pooled estimates and confidence intervals (95% confidence intervals [CI]). We calculated the odds ratios (OR) and 95% CI for the targets of mortality and hepatocellular carcinoma, fibrosis, and cirrhosis.
Results
Nine studies (N: 195,602 patients) reported data on mortality of patients affected by chronic viral hepatitis, six studies (N: 72,960) reported data on the risk to develop hepatocellular carcinoma, two studies on fibrosis progression (N: 9678) and two studies (N: 85,205) on cirrhosis development. Statins reduce the risk to develop hepatocarcinoma (OR (95% CI) = 0.47 (0.28, 0.81), p=0.005) (Figure 1), liver fibrosis (OR (95% CI) = 0.55 (0.34, 0.87), p<0.001), and cirrhosis (OR (95% CI) = 0.59 (0.55, 0.62), p<0.0001). There was also no significant link between statin therapy and alanine (Figure 2) and aspartate aminotransferases levels. Moreover, statin therapy is associated with a significant reduction in mortality but only in studies longer than 3 years (OR (95% CI) = 0.38 (0.17, 0.85), p=0.006).
Conclusion
Long-term treatment with statins seems to be safe in patients affected by hepatitis, while significantly improving their prognosis. Extensive education should be continued in order to avoid discontinuing statin therapy in patients with liver diseases.

Abstract
The latest European Guidelines of Arterial Hypertension have officially introduced uric acid evaluation among the cardiovascular risk factors that should be evaluated in order to stratify patient's risk. In fact, it has been extensively evaluated and demonstrated to be an independent predictor not only of all-cause and cardiovascular mortality, but also of myocardial infraction, stroke and heart failure. Despite the large number of studies on this topic, an important open question that still need to be answered is the identification of a cardiovascular uric acid cut-off value. The actual hyperuricemia cut-off (> 6 mg/dL in women and 7 mg/dL in men) is principally based on the saturation point of uric acid but previous evidence suggests that the negative impact of cardiovascular system could occur also at lower levels. In this context, the Working Group on uric acid and CV risk of the Italian Society of Hypertension has designed the Uric acid Right for heArt Health project. The primary objective of this project is to define the level of uricemia above which the independent risk of CV disease may increase in a significantly manner. In this review we will summarize the first results obtained and describe the further planned analysis.

Abstract
Abstract
Background
Recently, concerns regarding the safety of red yeast rice (RYR) have been raised after the publication of some case reports claiming toxicity.
Purpose
Since the previous meta-analyses on the effects of RYR were mainly focused on its efficacy to improve the lipid profile and other cardiovascular parameters, we carried out a meta-analysis on safety data derived from the available randomized controlled clinical trials (RCTs).
Methods
Primary outcomes were musculoskeletal disorders (MuD). Secondary outcomes were non-musculoskeletal adverse events (Non-MuD) and serious adverse events (SAE). Subgroups analyses were carried out considering the intervention (RYR alone or in association with other nutraceutical compounds), monacolin K administered daily dose (≤3, <3–5 and >5 mg/day), follow-up (>12 or ≤12 weeks), with statin therapy or statin-intolerance and type of control treatment (placebo or statin treatment).
Results
Data were pooled from 52 RCTs comprising 110 treatment arms, which included 8503 subjects, with 4421 in the RYR arm and 4287 in the control one. Monacolin K administration was not associated with increased risk of MuD (odds ratio [OR]=0.94, 95% confidence interval [CI] 0.53,1.65). (Figure below presents the forest plot comparing the RYR associated risk of MuD in the entire population). Moreover, we found a reduced risk of Non-MuD (OR=0.59, 95% CI 0.50, 0.69) and SAE (OR=0.54, 95% CI 0.46, 0.64) vs. control. Subgroups analyses confirmed the high tolerability profile of RYR. Furthermore, increasing daily doses of monacolin K were negatively associated with increasing risk of Non-MuD (slope: −0.10; 95% CI: −0.17, −0.03; two-tailed p<0.01).
Forest plot on RYR link with MuD risk.
Conclusions
Based on our data, RYR use as lipid-lowering dietary supplement seems to be overall tolerable and safe in a large population of moderately hypercholesterolaemic subjects.

Abstract
BACKGROUND AND AIMS Oxidized LDL (oxLDL) or pro-inflammatory stimuli lead to increased oxidative stress linked to endothelial dysfunction and atherosclerosis. The oxLDL receptor-1 (LOX1) is elevated within atheromas and cholesterol-lowering statins inhibit LOX1 expression. Berberine (BBR), an alkaloid extracted from plants of gender Berberis, has lipid-lowering and anti-inflammatory activity. However, its role in regulating LOX1-mediated signaling is still unknown. The aim of this study was to investigate the effect of BBR on oxLDL- and TNFα-induced endothelial dysfunction in human umbilical vein endothelial cells (HUVECs) and to compare it with that of lovastatin (LOVA). METHODS AND RESULTS Cytotoxicity was determined by lactate dehydrogenase assay. Antioxidant capacity was measured with chemiluminescent and fluorescent method and intracellular ROS levels through a fluorescent dye. Gene and protein expression levels were assayed by qRT-PCR and western blot, respectively. HUVECs exposure to oxLDL (30 μg/ml) or TNFα (10 ng/ml) for 24 h led to a significant increase in LOX1 expression, effect abrogated by BBR (5 μM) and LOVA (5 μM). BBR but not LOVA treatment abolished the TNFα-induced cytotoxicity and restored the activation of Akt signaling. In spite of a low direct antioxidant capacity, both compounds reduced intracellular ROS levels generated by treatment of TNFα but only BBR inhibited NOX2 expression, MAPK/Erk1/2 signaling and subsequent NF-κB target genes VCAM and ICAM expression, induced by TNFα. CONCLUSIONS These findings demonstrated for the first time that BBR could prevent the oxLDL and TNFα - induced LOX1 expression and oxidative stress, key events that lead to NOX, MAPK/Erk1/2 and NF-κB activation linked to endothelial dysfunction. CHEMICAL COMPOUNDS STUDIED IN THIS ARTICLE Berberine (PubChem CID: 2353); Lovastatin (PubChem CID: 53232).

Our aim was to study and compare pharmacoepidemiology of headache treatment in two different settings: inside and outside a specialized Centre. We analysed the differences in headache treatment between 612 subjects admitted for the first visit (‘naive’) (F/M: 2.41; mean age = 37.31 ± 14.09 years) and 620 subjects admitted for a control visit (F/M: 3.18; mean age = 44.30 ± 15.37 years) to the Headache Centre of the University of Modena and Reggio Emilia. Most patients suffered from migraine. As acute treatment, on the first visit, 49.4% of them were taking drugs prescribed by a doctor; 41.5% were taking over-the-counter analgesics (OTCAs); 9.1% were not taking any drug. On the control visit, 81.3% of patients were taking prescription drugs; 15.8% OTCAs; 2.9% were not taking drugs (overall chi-square = 139.229, P < 0.001). Non-selective analgesics were the most-used drugs. Triptans were used by 9.1% of ‘naive’ patients and by 31.8% of patients attending for the control visit (Fisher's Z = 7.655, P < 0.001). Nimesulide was the most-used drug. A prophylactic treatment was made by 16.8% of ‘naive’ patients, and by 58.2% of patients admitted to the control visit (Fisher's Z = 12.135, P < 0.001). Antidepressants were the class of drugs most used for prophylaxis. Amitriptyline was the drug for prophylaxis most frequently used by patients attending the control visit, while flunarizine was the most frequently used by ‘naive’ patients. Before being examined in a specialized centre, few patients take prescription drugs, triptans, or prophylactic drugs; specialized care increases the proportion of patients taking prophylactic drugs, and changes the type of acute treatment used into disease-specific medication for headache.

Abstract
Our aim was to compare the need for analgesics/drugs of abuse between headache patients—chronic and episodic headache sufferers—and addicts, by the Leeds Dependence Questionnaire (LDQ). This is a self-completion 10-item instrument to measure dependence upon a variety of substances. We administered the LDQ questionnaire to 122 chronic daily headache (CDH) sufferers who had been taking one dose of analgesic drug every day for at least 1 year; 71 subjects suffering from episodic headache (EH) using analgesics only occasionally; 115 consecutive drug addicts (DA) with a diagnosis of substance dependence. The mean LDQ total score was similar in the CDH (11.58 ± 6.35) and DA (10.37 ± 6.51) groups, and for both it was significantly higher than the score in the EH (5.61 ± 3.00) group ( P < 0.001). The CDH group had the highest scores, and higher scores than the DA group (Z = −8.18, P < 0.001) in item 8, assessing the primacy of effect over the kind of analgesic used, and in item 10 (Z = −5.03, P < 0.001), asking if it is difficult to live without the analgesic; the DA group had the highest scores, and higher scores than the CDH group, in item 9 (Z = −5.07, P < 0.001) addressing the need for the continued administration of the drug to maintain well-being, and in item 3 (Z =−2.39, P < 0.05), exploring compulsion to start the use of the drug. The EH group had lower scores in all items ( P < 0.05) except for item 9, where there was no difference from CDH group; the EH group had also lower scores ( P < 0.001) than the DA group, except for item 8, where, instead, the score was higher than in the DA group (Z = −5.33, P < 0.001). A strong link develops between chronic headache patients and the analgesics they use. This sort of ‘dependence’ appears to be a consequence of headache, originating from the necessity for the analgesic to cope with everyday life.

Abstract
We evaluated the effect of glimepiride plus metformin and rosiglitazone plus metformin on glucose, and on cardiovascular risk parameters such as lipoprotein(a) (Lp[a]) and homocysteine (HCT) in patients with type 2 diabetes and metabolic syndrome. Ninety-nine patients in the multicentre, randomized, double-blind study took metformin (1500 mg/day) plus glimepiride (2 mg/day) or rosiglitazone (4 mg/day) for 12 months. Changes in body mass index, glycosylated haemoglobin (HbA1c), Lp(a) and HCT were primary efficacy variables. Fasting plasma glucose (FPG), post-prandial plasma glucose (PPG) and homeostasis model assessment index were also used to assess efficacy. On average, HbA1c decreased by 9.1% and 8.1%, FPG decreased by 7.3% and 10.9%, and PPG decreased by 7.6% and 10.5%, respectively, in the glimepiride and rosiglitazone groups after 12 months. Patients receiving rosiglitazone experienced more rapid improvement in glycaemic control than those on glimepiride, and showed a significant improvement in insulin resistance-related parameters. There was a statistically significant decrease in basal homocysteinaemia in glimepiride-treated patients (−27.3%), but not in rosiglitazone-treated patients. Rosiglitazone plus metformin significantly improved long-term control of insulin resistance-related parameters compared with glimepiride plus metformin, although glimepiride treatment was associated with a slight improvement in cholesterolaemia, not observed in the rosiglitazone-treated patients, and with significant improvements in non-traditional risk factors for cardiovascular disease, such as basal homocysteinaemia and plasma Lp(a) levels.

Abstract
In this multicentre, randomized, double-blind, controlled, parallel-group trial, 103 patients with type 2 diabetes mellitus and metabolic syndrome were randomized to receive one of two thiazolidinediones – pioglitazone or rosiglitazone – in combination with 1500 mg/day of metformin, increasing up to 3000 mg/day, for 12 months. Anthropometric, metabolic, coagulation and fibrinolysis parameters were assessed at baseline and after 3, 6, 9 and 12 months. Significant decreases in glycosylated haemoglobin, fasting plasma glucose and post-prandial plasma glucose levels were seen after 9 and 12 months in both groups, and significant decreases in fasting plasma insulin and post-prandial plasma insulin levels were seen after 12 months in both groups. In both groups, improvement in the homeostasis model assessment index compared with baseline was obtained only after 12 months. Plasminogen activator inhibitor-1 levels were significantly lower in both groups after 12 months compared with baseline values. In patients with type 2 diabetes mellitus and metabolic syndrome, the combination of metformin plus thiazolidinediones improved glycaemic control and produced a slight but significant reduction in plasminogen activator inhibitor-1 levels.

Abstract
OBJECTIVE Metamucil® is a fiber supplementation formed by 100% natural psyllium. This study, conducted in Italy, assessed the impact of quality of pharmacists' instruction to use this product on subjects' adherence to and overall satisfaction with this test product. SUBJECTS AND METHODS Open-label post-marketing study involving adult subjects who had purchased Metamucil® (follow-up: 14 ± 7 days). Information was collected using questionnaires dedicated to the participating subject and pharmacy. RESULTS In total, 1480 subjects and 182 pharmacies returned their questionnaires. The mean age of the subjects was 49 years, two-thirds were female and 87% went to the pharmacy with problems related to bowel movements. The median daily dose taken over the 21-day period was 1. Adherence to the test product was associated with the quality of pharmacist's counseling (p = 0.005). Similarly, satisfaction with the tested product was associated with the quality of counseling (p < 0.001). Consumers' satisfaction was also associated with the quality of pharmacist's explanation of the benefits of the test product (p < 0.001) and with adherence (p < 0.001). 93% and 83% of subjects, respectively, stated the ease of use and their overall satisfaction with the test product, with 73% of subjects agreeing that they would continue using it. Similar findings were observed in subjects who had previously taken the most commonly used branded fiber supplements containing either partially hydrated guar gum or psyllium in the previous 6 months. 92% of pharmacists stated they would recommend Metamucil® for bowel regularity and 90% as it provides multiple benefits. CONCLUSIONS Pharmacists' counseling is associated with consumers' adherence and satisfaction to Metamucil®. A large proportion of subjects were satisfied and would continue taking the tested product as a fiber supplement.

Abstract
AIM To identify and quantify the role of different risk factors in the long-term development of IFG and T2DM in a rural Italian population sample with family history of T2DM. METHODS We selected a sample of 1271 adult subjects from among those 1851 consecutively visited during four consecutive Brisighella Heart Study surveys (1996-2008), then selecting those ones with a family history of T2DM. Thus, we obtained a final sample including 545 subjects and for which a full clinical and ematochemistry data set was available. RESULTS The Cox-regression model better predicting the incident IFG and T2DM included age, gender, FPG, TG and SUA. The model best predicting the incident IFG status alone (without T2DM) is very similar to that predicting both IFG and T2DM, including the same predictors. Finally, the model best predicting T2DM (excluding IFG) simply includes FPG, BMI and ALT/AST ratio. Repeating the Cox-regression analysis using BMI as a covariate, TG appears to be also a significant predictor of T2DM (HR 1.018 95% CI 1.009-1.041, p=0.013). CONCLUSION In a sample of subjects with a family history of diabetes the best long-term predictors of IFG are age, gender, FPG, TG and SUA, while those of T2DM are FPG and BMI.

Abstract
AIMS To evaluate which triple oral therapy between metformin + pioglitazone + sitagliptin and metformin + pioglitazone + glibenclamide can be more useful in improving glycaemic control and should be preferred in clinical practice. METHODS During the 2-year run-in period, patients were instructed to take metformin monotherapy for the first year, then a combination of metformin and pioglitazone for the second year, then patients were randomized to add glibenclamide or sitagliptin to the dual combination of metformin and pioglitazone for another year. RESULTS Body weight reached with sitagliptin at 36 months was lower than that reached with glibenclamide. Fasting plasma insulin and homeostasis model assessment of insulin resistance were significantly increased by triple therapy with glibenclamide and decreased by that with sitagliptin. While sitagliptin did not change homeostasis model assessment of β-cell function, this value was significantly increased by glibenclamide. Fasting plasma proinsulin was not influenced by triple oral therapy including glibenclamide, while it was decreased by the therapy including sitagliptin compared to glibenclamide. Triple oral therapy with sitagliptin better improved β-cell function measures compared with the glibenclamide therapy. CONCLUSIONS Sitagliptin should be preferred to glibenclamide as an addition to the metformin + pioglitazone combination for its better protection of β-cell secretion and its neutral effect on body weight.

Abstract
Our aim was to evaluate the predictors of Isoleucine-Proline-Proline/Valine-Proline-Proline (IPP-VPP) lactotripeptides (LTPs) antihypertensive effect in the context of a short-term large double-blind randomized clinical trial involving 164 pharmacologically untreated subjects in primary prevention for cardiovascular disease. When compared with the baseline, office systolic blood pressure (SBP) (-3.42 mm Hg, P < .001) and diastolic blood pressure (DBP) (-2.35 mm Hg, P < .001) significantly decreased, in the LTP-treated patients only. No significant change in predictors during the study of ambulatory blood pressure measurement (ABPM) parameters was observed. A short-term supplementation with LTPs significantly improves the office SBP and DBP, especially in male subjects. The main predictor of LTP antihypertensive effect was the baseline BP.

Abstract
WHAT IS KNOWN AND OBJECTIVE The behavioural approach is usually slow and not always sufficient to achieve optimal targets in weight and metabolic control in obese diabetic patients, and a pharmacological treatment is often necessary. The aim of this study was to compare the effects of orlistat and placebo on body weight, glycaemic and lipid profile and insulin resistance in patients with type 2 diabetes. METHODS Two hundred and fifty-four obese, diabetic patients were enrolled in this study and randomized to take orlistat 360mg or placebo for 1year. We evaluated at baseline and after 3, 6, 9 and 12months body weight, waist circumference (WC), body mass index (BMI), glycated haemoglobin (HbA(1c) ), fasting plasma glucose (FPG), post-prandial plasma glucose (PPG), fasting plasma insulin (FPI), homeostasis model assessment insulin resistance index (HOMA-IR), lipid profile, retinol-binding protein-4 (RBP-4), resistin, visfatin and high-sensitivity C-reactive protein (Hs-CRP). RESULTS AND DISCUSSION We observed a significant reduction in body weight, WC, BMI, lipid profile, RBP-4 and visfatin in the orlistat group but not in control group. Faster improvements in HbA(1c) , PPG, FPI, HOMA-IR, resistin and Hs-CRP were recorded with orlistat than with placebo. A similar decrease in FPG was seen in the two groups. Significant predictors of change in insulin resistance (HOMA-IR) were RBP-4 and resistin concentration in the orlistat group (r=-0·53, P<0·05, and r=-0·59, P<0·01, respectively). WHAT IS NEW AND CONCLUSION To the best of our knowledge, this is the first study investigating the effect of orlistat on insulin resistance and markers of inflammation. Orlistat improved lipid profile and led to faster glycaemic control and insulin resistance parameters than the control, without any serious adverse event. Orlistat also improved RBP-4 and visfatin, effects not observed with placebo.

Abstract
BACKGROUND Sex hormones and adipokines seem to differently interact in both genders at different ages. AIM To comparatively evaluate the serum level of adipokines and sex hormones in healthy non-pharmacologically treated premenopausal women, post-menopausal women, and elderly women, and in age-matched men. SUBJECTS From the historical cohort of the Brisighella Heart Study we selected 199 adult healthy subjects (males: 89; females: 110), aged 62.5±12.4 yr. Men and women included in the age-class subgroups were matched for body mass index (BMI), waist circumference, blood pressure, heart rate, fasting plasma glucose, plasma lipids. RESULTS Leptin did not differ among various age classes in men, while pre-menopausal women displayed significantly lower serum leptin than post-menopausal women (-6.7 ± 2.2 pg/ml, p=0.036). Post-menopausal women had significantly greater serum leptin when compared with age-matched men (+13.1 ± 2.0 pg/ml, p<0.001); the same was observed for elderly women when compared with elderly men (+11.2 ± 2.3 pg/ml, p<0.001). At any age, women had significantly lower serum testosterone/estrone ratio than age-matched men (p<0.01). Serum DHEAS was inversely proportional to age in both genders. The main predictors of adiponectin level are age in men (p=0.027) and BMI in women (p=0.003). The main predictors of leptin level are BMI and the testosterone/estrone ratio in both sexes (p<0.05). The testosterone/estrone ratio is also the main predictor of ghrelin levels in women (p=0.006). CONCLUSION Sex hormones and adipokines show specific interactions in the two genders and in different age-classes in a representative sample of adult healthy subjects.

Abstract
The aim of the study was to evaluate the effect of pioglitazone and glibenclamide on lipid profile and inflammatory parameters during an oral fat load (OFL). A total of 201 type 2 diabetic patients on treatment with metformin were enrolled in the study; pioglitazone was titrated till 45 mg/day and glibenclamide till 15 mg/day, in association with metformin, respectively. The patients underwent an OFL at baseline and after 12 months. The OFL was given between 08.00 and 09.00 h after a 12-h fast. Blood samples were drawn before and 3, 6, 9, and 12 h after the OFL. We evaluated glycemic-metabolic parameters [glycated hemoglobin (HbA (1c)), fasting plasma glucose (FPG), fasting plasma insulin (FPI), homeostasis model assessment (Homa) index], total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), triglycerides (Tgs), interleukin-6 (IL-6), high sensitivity C-reactive protein (Hs-CRP), tumor necrosis factor-α (TNF-α), and adiponectin (ADN). Pioglitazone was better than glibenclamide in decreasing HbA (1c), FPG, FPI, lipid profile, and in improving inflammatory parameters such as Hs-CRP, and ADN. Comparing the OFL performed at baseline, and the OFL performed at the end of the study, pioglitazone, but not glibenclamide, improved all post-OFL peaks for all parameters. Comparing the 12 months OFL in the group treated with pioglitazone and in the group treated with glibenclamide, the values recorded with pioglitazone were significantly better than the ones obtained with glibenclamide. We can conclude that pioglitazone was better than glibenclamide in mitigating the variations of lipid components and inflammation parameters in type 2 diabetic patients.

Abstract
BACKGROUND AND AIM Some clinical evidence supports a statin antihypertensive effect. Our aim is to evaluate the statin effect on blood pressure control in hypertensive patients in the setting of clinical practice, and the role of some predetermined individual patient characteristics (age, gender, baseline BP levels, pre-treatment LDL-C levels) on the supposed statin BP lowering effect. METHODS AND RESULTS Two hundred and fifty-four hypertensive patients with hypercholesterolemia were enrolled in the Ambulatory service of the Hypertension Research Unit of Bologna University Hospital. After 2-4 weeks of a run-in period patients were allocated to statin treatment and followed-up for 24 weeks. The blood pressure response to statins was compared in several subgroups of patients according to age, gender, baseline BP and pre-treatment cholesterolemia. In the overall study population, the use of statins was associated with a significant reduction in systolic (-7.6+/-4 mmHg, p<0.05) and diastolic blood pressures (-5.2+/-3 mmHg, p<0.05) in comparison to baseline. The blood pressure decrease was more pronounced in patients younger than 65 years (p<0.05), with higher baseline systolic blood pressure (p<0.005), and in those with higher cholesterolemia before statins (p<0.05). CONCLUSIONS Our study suggests a BP-lowering effect of statins, consistent with some other literature. Some parameters like age, baseline systolic blood pressure and cholesterolemia influence the antihypertensive effect of statins. The lack of consideration for these confounding factors may be one of the reasons for the conflicting results about the BP lowering effects of statins.

Abstract
BACKGROUND Incretin-based therapies have provided additional options for the treatment of type 2 diabetes mellitus. The aim of our study was to evaluate the effects of exenatide compared to glibenclamide on body weight, glycemic control, beta-cell function, insulin resistance, and inflammatory state in patients with diabetes. METHODS One hundred twenty-eight patients with uncontrolled type 2 diabetes mellitus receiving therapy with metformin were randomized to take exenatide 5 microg twice a day or glibenclamide 2.5 mg three times a day and titrated to exenatide 10 microg twice a day or glibenclamide 5 mg three times a day. We evaluated body weight, body mass index (BMI), glycated hemoglobin (HbA(1c)), fasting plasma glucose (FPG), postprandial plasma glucose (PPG), fasting plasma insulin (FPI), homeostasis model assessment insulin resistance (HOMA-IR) index, homeostasis model assessment beta-cell function (HOMA-beta) index, plasma proinsulin (PPr), PPr/FPI ratio, resistin, retinol binding protein-4 (RBP-4), and high-sensitivity C-reactive protein (Hs-CRP) at baseline and after 3, 6, 9, and 12 months. RESULTS Body weight and BMI decreased with exenatide and increased with glibenclamide. A similar improvement of HbA(1c), FPG, and PPG was obtained in both groups, whereas FPI decreased with exenatide and increased with glibenclamide. The HOMA-IR index decreased and the HOMA-beta index increased with exenatide but not with glibenclamide. A decrease of PPr was reported in both groups, but only glibenclamide decreased the PPr/FPI ratio. Resistin and RBP-4 decreased with exenatide and increased with glibenclamide. A decrease of Hs-CRP was obtained with exenatide, whereas no variations were observed with glibenclamide. CONCLUSIONS Both exenatide and glibenclamide gave a similar improvement of glycemic control, but only exenatide gave improvements of insulin resistance and beta-cell function, giving also a decrease of body weight and of inflammatory state.

Abstract
The aim of this study was to evaluate the effect of an oral glucose tolerance test (OGTT) on the level of endothelial dysfunction and vascular inflammation markers in healthy subjects (H) and diabetic overweight patients (D). We enrolled 256 healthy subjects and 274 type 2 diabetic patients. We evaluated blood glucose (BG), soluble intercellular adhesion molecule-1 (sICAM-1), interleukin-6 (IL-6), high-sensitivity C reactive protein (hsCRP), soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble E-selectin (sE-selectin), and tumor necrosis factor-alpha (TNF-alpha) at baseline and after OGTT. We observed that BG, sICAM-1, IL-6, hs-CRP, sVCAM-1, sE-selectin, and TNF-alpha values were higher in D group than in H group. In a large sample of adult healthy subjects and type 2 diabetics we observed that both answer to an OGTT with a significant increase in biomarkers of systemic low-grade inflammation and endothelial dysfunction such as hsCRP, IL-6, TNF-alpha, sICAM-1, sVCAM-1, and sE-selectin. Type 2 diabetics experienced, however, a more significant increase in TNF-alpha, and sE-selectin.

Abstract
We evaluate the effect of a standardized dietary supplementation with omega-3 polyunsaturated fatty acids (n-3 PUFAs) on the level of some markers of vascular remodeling in patients with combined dyslipidemia. Three hundred and thirty-three patients received placebo or n-3 PUFAs for 6 months. We evaluated body mass index, glycemic profile, blood pressure, lipid profile, lipoprotein(a), plasminogen activator inhibitor-1, homocysteine, fibrinogen, high-sensitivity C reactive protein, ADP, MMP-2 and MMP-9, and tissue inhibitors of metalloproteinase-1 and -2. A significant increase of high-density lipoprotein-cholesterol, and a significant decrease of triglycerides were present after 3 and 6 months with n-3 PUFAs intake. A significant plasminogen activator inhibitor-1, fibrinogen and high-sensitivity C reactive protein decrease was obtained after 3 and 6 months and a significant ADP increase was observed after 3 and 6 months of n-3 PUFAs. A significant MMP-2, MMP-9, tissue inhibitors of metalloproteinase-1 and tissue inhibitors of metalloproteinase-2 decrease was obtained after 6 months compared to the baseline value with n-3 PUFAs intake. n-3 PUFAs give a better lipid profile and a better improvement of coagulation, fibrinolytic and inflammatory parameters than placebo. Furthermore, lowers levels of MMP-2, MMP-9 and their tissue inhibitors are obtained with n-3 PUFAs compared to placebo.

Abstract
Lepidium meyenii (Maca) is a cultivated root belonging to the brassica family used in the Andean region for its supposed aphrodisiac properties. We carried out a double-blind clinical trial on 50 Caucasian men affected by mild erectile dysfunction (ED), randomised to treatment with Maca dry extract, 2400 mg, or placebo. The treatment effect on ED and subjective well-being was tested administrating before and after 12 weeks the International Index of Erectile Function (IIEF-5) and the Satisfaction Profile (SAT-P). After 12 weeks of treatment, both Maca- and placebo-treated patients experienced a significant increase in IIEF-5 score (P < 0.05 for both). However, patients taking Maca experienced a more significant increase than those taking placebo (1.6 +/- 1.1 versus 0.5 +/- 0.6, P < 0.001). Both Maca- and placebo-treated subjects experienced a significant improvement in psychological performance-related SAT-P score, but the Maca group higher than that of placebo group (+9 +/- 6 versus +6 +/- 5, P < 0.05). However, only Maca-treated patients experienced a significant improvement in physical and social performance-related SAT-P score compared with the baseline (+7 +/- 6 and +7 +/- 6, both P < 0.05). In conclusion, our data support a small but significant effect of Maca supplementation on subjective perception of general and sexual well-being in adult patients with mild ED.

Abstract
The data reported in literature revealed a novel function for matrix metalloproteinases (MMPs) as modulators of adipogenesis. However, their expression profile and role in the cellular microenvironment during obesity-mediated adipose tissue development remain poorly defined. The authors hypothesized that MMP-2 and MMP-9 levels might be abnormal in obesity, reflecting alterations in extracellular matrix (ECM) turnover. One hundred and sixty three obese patients and 165 controls were enrolled. The following were measured: body mass index (BMI), waist circumference (WC), fasting plasma glucose (FPG), fasting plasma insulin (FPI), homeostasis model assessment (HOMA) index, systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (Tg), lipoprotein(a) (Lp(a)), and plasma levels of MMP-2 and MMP-9. A significant increase of BMI and WC (p< .0001) was observed in obese patients. No FPG change was present in obese group, whereas FPI and HOMA index increases (p< .0001) were obtained in obese patients compared to control subjects. No SBP and DBP variations were observed in obese group. Significant TC and LDL-C increases (p< .0001) were present in obese patients, whereas no HDL-C, Tg, and Lp(a) changes were obtained in both groups. MMP-2 and MMP-9 levels were significantly higher in obese group (p< .0001). Plasma levels of MMP-2 and MMP-9 are increased in obese patients which may reflect abnormal ECM metabolism.

Abstract
Familial combined hyperlidemia (FCH) is a common metabolic disorder characterized by: (a) increase in cholesterolemia and/or triglyceridemia in at least two members of the same family, (b) intra-individual and intrafamilial variability of the lipid phenotype, and (c) increased risk of premature coronary heart disease (CHD). FCH is very frequent and is one of the most common genetic hyperlipidemias in the general population (prevalence estimated: 0.5%-2.0%), being the most frequent in patients affected by CHD (10%) and among acute myocardial infarction survivors aged less than 60 (11.3%). This percentage increases to 40% when all the myocardial infarction survivors are considered without age limits. However, because of the peculiar variability of laboratory parameters, and because of the frequent overlapping with the features of metabolic syndrome, this serious disease is often not recognized and treated. The aim of this review is to define the main characteristics of the disease in order to simplify its detection and early treatment by all physicians by mean of practical guidelines.

Abstract
BACKGROUND AND OBJECTIVE Angiotensin II receptor blockers represent a class of effective and well-tolerated orally active antihypertensive drugs in the general hypertensive population and in diabetic patients. The aim of our study was to investigate the metabolic effects of telmisartan and irbesartan in diabetic subjects treated with rosiglitazone. METHODS We evaluated 188 type 2 diabetic patients with metabolic syndrome. All patients took a fixed dose of 4 mg rosiglitazone/day. We administered 40 mg telmisartan/day or 150 mg irbesartan/day and evaluated their body mass index, glycosylated haemoglobin (HbA(1c)), fasting plasma glucose (FPG), fasting plasma insulin (FPI), homeostasis model assessment-index (Homa-IR), total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol, triglycerides, systolic blood pressure, diastolic blood pressure, adiponectin and resistin during 12 months of this treatment. RESULTS AND DISCUSSION In addition to a comparable antihypertensive effect for telmisartan and irbesartan after 6 and 12 months, both treatments were associated with a significant reduction in TC and LDL-C plasma levels compared with baseline. After 6 months of treatment, only the telmisartan group experienced a significant improvement in (HbA(1c)), FPG, Homa-IR, adiponectin and resistin compared with the baseline values, whereas both drug regimens were associated with a significant improvement in these parameters after 12 months. However, the improvements observed in the telmisartan group were significantly larger than that noted in the irbesartan group after 12 months of treatment. FPI significantly decreased only after 12 months of treatment in both groups, but again, the reduction was significantly larger in the telmisartan-treated subjects. CONCLUSIONS Telmisartan seemed to improve glycaemic and lipid control and metabolic parameters of the metabolic syndrome better than irbesartan. These differences could be relevant in the choice of therapy for this condition and diabetes.

Abstract
OBJECTIVES We hypothesized that molecules active in vascular remodeling (i.e. MMPs and their TIMPs) could be modified in diabetic patients, as indirect markers of the diabetes related generalized abnormality of vascular activity. To test this hypothesis, we measured the plasma levels of MMP-2, MMP-9, TIMP-1, and TIMP-2 in type 2 diabetic patients and in healthy subjects. METHODS We enrolled 181 diabetic patients and 165 controls. We measured body mass index (BMI), glycosylated hemoglobin (HbA(1c)), fasting plasma glucose (FPG), fasting plasma insulin (FPI), homeostasis model assessment index (HOMA index), systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), triglycerides (Tg), lipoprotein(a) [Lp(a)], plasminogen activator inhibitor-1 (PAI-1), homocysteine (Hct) fibrinogen (Fg), high sensitivity C-reactive protein (hs-CRP), and plasma levels of MMP-2, MMP-9, TIMP-1, and TIMP-2. RESULTS A significant increase (P<0.0001) of BMI, HbA(1c), FPG, FPI, HOMA index, SBP, DBP, TC, LDL-C, Tg, Lp(a), PAI-1, Hct, Fg, and hs-CRP was present in the diabetic group, with a significant decrease (P<0.0001) of HDL-C levels compared to healthy subjects. MMP-2 and MMP-9 levels were significantly higher (P<0.0001) in diabetic patients. Significant TIMP-1, and TIMP-2 increase was also observed (P<0.0001) in the diabetic group. CONCLUSION Plasma levels of MMP-2, MMP-9, TIMP-1, and TIMP-2 are increased in diabetic patients which may reflect abnormal extracellular matrix (ECM) metabolism.

Abstract
BACKGROUND Albuminuria is the best and most readily available marker for glomerular damage and progressive renal function loss in patients with diabetic nephropathy. Recently, administration of the oral glycosaminoglycan sulodexide (a mixture of 80% fast-moving heparin and 20% dermatan sulphate) was shown to effectively decrease albumin excretion rate in diabetics with nephropathy. AIMS To evaluate whether the hypoalbuminuric effect of sulodexide is associated with improvement of the renal vascular or tubule function. METHODS Forty-five type 1 diabetic patients, affected by diabetic nephropathy with albuminuria for at least 5 years, were randomly allocated to sulodexide or untreated. Those allocated to sulodexide were given 100 mg of sulodexide daily for 120 days. Renal vascular function (DIR) and N-acetyl-beta-D-glucosaminidase (NAG) excretion were estimated before and at the end of the study, the former in thesulodexide group only. DIR was measured as two Cr(cl) lasting 120 min (before and during 2 mug/kg b.w. i.v. dopamine). RESULTS The analysis of trends during the study demonstrated a marked reduction of albuminuria in the sulodexide group (from 126.1 +/- 15.41 to 93.6 +/- 13.7 mg/day). DIR rose from 13.2 +/- 2.1% to 15.44 +/- 1.9% (relative increase: +16.9%), and NAG excretion showed a decreasing trend decreased in the sulodexide group only (from 5.1 +/- 0.62 to 4.7 +/- 0.40 U/g(creat)). CONCLUSION The findings presented in this study indicate for the first time that orally available sulodexide may favorably affect the renal vascular function in type 1 diabetic patients with nephropathy and microalbuminuria. The effect of sulodexide on NAG is strongly influenced by the baseline NAG values, with a significant NAG reduction in the patients with the highest baseline NAG values.

Abstract
BACKGROUND Metformin is considered the gold standard for type 2 diabetes treatment as monotherapy and in combination with sulphonylureas and insulin, whereas the combination of metformin with thiazolidinediones is relatively less studied. The aim of the present study was to assess the differential effect on glycaemic metabolism and lipid variables of the combination of metformin plus pioglitazone or metformin plus rosiglitazone in diabetic patients with metabolic syndrome. METHODS All patients began metformin and were randomized to receive pioglitazone or rosiglitazone for 12 months. We assessed body mass index, glycated haemoglobin, fasting plasma glucose, postprandial plasma glucose, fasting plasma insulin, postprandial plasma insulin, homeostasis model assessment index, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, apolipoprotein A-I, and apolipoprotein B. RESULTS Significant decreases in glycated haemoglobin, fasting plasma glucose, postprandial plasma glucose, fasting plasma insulin, and postprandial plasma insulin were seen after 9 and 12 months in both groups. Homeostasis model assessment index improved at 12 months in both groups. Significant total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, apolipoprotein A-I, and apolipoprotein B improvement was observed in pioglitazone group after 12 months, but not in the rosiglitazone group. These variations were significant between groups. CONCLUSION The combination of metformin plus thiazolidinediones was able to improve glycaemic control compared with previous therapy. Pioglitazone was associated with a significant improvement in lipid and lipoprotein variables.

Abstract
OBJECTIVES To assess the chronologic relationship between the cessation of smoking and the restoration of erectile function. Smoking is associated with an increased risk of erectile dysfunction. METHODS Twenty active smokers (20 to 40 cigarettes/day) affected by erectile dysfunction (International Index of Erectile Function 5-item score less than 21) were enrolled in the study. The mean age was 40 years. All the patients underwent penile color Doppler ultrasonography during the basic and dynamic phases (10 microg prostaglandin E1). A second Doppler evaluation was performed 24 to 36 hours after cessation of smoking. The peak systolic velocity (PSV) and end-diastolic velocity (EDV) were recorded. The PSV and EDV cutoff value was 30 cm/s and 5 cm/s, respectively. RESULTS Of the 20 patients, 10 (50%) had normal PSV values but only 5 (25%) had normal EDV values at the baseline Doppler evaluation. All the patients (100%) had normal PSV values at the second penile Doppler evaluation after smoking withdrawal, and 17 (85%) also had normal EDV values. The average PSV was 40.1 and 50.3 cm/s (P = 0.09) and the mean EDV was 6.8 and 2.4 cm/s (P <0.01) at the baseline penile Doppler examination and after smoking withdrawal, respectively. CONCLUSIONS Within 24 to 36 hours of the cessation of cigarette smoking, the color Doppler parameters demonstrated a significant improvement in EDV and a trend toward an increase in PSV. Additional clinical evaluation is required to further characterize the expeditious improvement in erectile function after the cessation of smoking.

Abstract
BACKGROUND AND OBJECTIVE Metformin is considered the gold standard for type 2 diabetes treatment as monotherapy and in combination with sulphonylureas and insulin. The combination of metformin with thiazolidinediones is less well studied. The aim of the present study was to assess the differential effect, and tolerability, of metformin combined with pioglitazone or rosiglitazone on glucose, coagulation and fibrinolysis parameters in patients with type 2 diabetes mellitus and metabolic syndrome. METHODS This 12-month, multicentre, double-blind, randomized, controlled, parallel-group trial was conducted at three study sites in Italy. We assessed patients with type 2 diabetes mellitus (duration >or=6 months) and with metabolic syndrome. All patients were required to have poor glycaemic control with diet, or experienced adverse effects with diet and metformin, administered up to the maximum tolerated dose. Patients were randomized to receive either pioglitazone or rosiglitazone self-administered for 12 months. We assessed body mass index (BMI), glycaemic control [glycosylated haemoglobin (HbA(1c)), fasting and postprandial plasma glucose and insulin levels (FPG, PPG, FPI, and PPI respectively), homeostasis model assessment (HOMA) index], lipid profile [total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C) and triglycerides (TG)], lipoprotein (a) [Lp(a)] and homocysteine (HCT) at baseline and at 3, 6, 9 and 12 months of treatment. RESULTS AND DISCUSSION No BMI change was observed at 3, 6, 9 and 12 months in either group. Significant HbA(1c) decreases were observed at 9 and 12 months in both groups. After 9 and 12 months, mean FPG and PPG levels decreased in both groups. Decreases in FPI and PPI were observed at 9 and 12 months compared with the baseline in both groups. Furthermore, in both groups, the HOMA index improved but only at 12 months. Significant TC, LDL-C, HDL-C, TG improvement was present in the pioglitazone group at 12 months compared with the baseline values, and these variations were significantly different between groups. No TC, LDL-C, TG improvement was present in the rosiglitazone group after 12 months. Significant Lp(a) and HCT improvement was present in the pioglitazone group at 12 months compared with the baseline values, and Lp(a) change was significant compared with the rosiglitazone group. Significant HCT decrease was observed in the rosiglitazone group at the end of the study. In our type 2 diabetic patients, both drugs were safe and effective for glycaemic control and improving HCT plasma levels. However, long-term treatment with metformin plus pioglitazone significantly reduced Lp(a) plasma levels, whereas metformin + rosiglitazone did not. CONCLUSION For patients with type 2 diabetes mellitus and metabolic syndrome, combined treatment with metformin and rosiglitazone or pioglitazone is safe and effective, However, the pioglitazone combination also reduced the plasma Lp(a) levels whereas the rosiglitazone combination did not.

Abstract
The aim of this study was to assess the influence of chronic therapy with phosphodiesterase type-5 inhibitor on penile haemodynamics at colour Doppler ultrasound. Thirty patients affected by erectile dysfunction (ED) of different aetiology tested with the International Index of Erectile Function (IIEF-5) were evaluated with penile colour Doppler ultrasound during basic and dynamic phases (10 microg PGE1) before and after chronic self-administration of sildenafil citrate (dosage: 100 mg as required, two to three times a week) for a period of 5-20 months (mean: 12.3). Treatment was interrupted 14-21 days before the second ultrasound evaluation. Peak systolic velocity (PSV) and end-diastolic velocity (EDV) were recorded by means of colour Doppler; cut off values were 25 and 5 cm s(-1) respectively. Data were compared by nonparametric tests. Twenty-two of the 30 patients showed normal pre-treatment PSV, while eight of 30 had an insufficient arterial flow. Mean pre-treatment EDV was 4.7 +/- 0.5. After chronic therapy with sildenafil, a global improvement of 10.5% on PSV was seen (P < 0.001), without any statistical difference between patients with normal pre-treatment peak and those with a borderline one. No statistically significant changes were found for EDV (P = 0.98). It is concluded that chronic therapy with phosphodiesterase-5 inhibitor results in a significant improvement in PSV values, probably due to a penile chronic vasoactive enhancement.

Abstract
AIM Accumulating evidence suggests that combination therapy using oral antidiabetic agents with different mechanisms of action may be highly effective in achieving and maintaining target blood glucose levels. The aim of our study is to evaluate the differential effect on glucose and lipid parameters of the association between glimepiride plus metformin and rosiglitazone plus metformin in patients affected by type 2 diabetes and metabolic syndrome. METHODS Patients were enroled, evaluated and followed at two Italian centres. We evaluated 99 type 2 diabetic patients with metabolic syndrome (48 males and 47 females; 23 males and 24 females, aged 52 +/- 5 with glimepiride; 25 males and 23 females, aged 54 +/- 4 with cglitazone). All were required to have been diagnosed as being diabetic for at least 6 months and did not have glycaemic control with diet and oral hypoglycaemic agents such as sulphonylureas or metformin, both to the maximum tolerated dose. All patients took a fixed dose of metformin, 1500 mg/day. We administered glimepiride (2 mg/day) or rosiglitazone (4 mg/day) in a randomized, controlled, double-blind clinical study. We evaluated body mass index (BMI), glycaemic control, lipid profile [total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol and triglycerides] and lipoprotein parameters [apolipoprotein A-I and apolipoprotein B (Apo B)] during 12 months of this treatment. RESULTS A total of 95 patients completed the study. Significant BMI decrease was observed at 12 months in glimepiride and rosiglitazone group (p < 0.05 and p < 0.01 respectively) as well as of glycated haemoglobin decrease (p < 0.05 and p < 0.01 respectively), mean fasting plasma glucose and postprandial plasma glucose levels (p < 0.05 and p < 0.01 respectively). A decrease in fasting plasma insulin and postprandial plasma insulin at 12 months (p < 0.05 and p < 0.01 respectively) compared with the baseline value in rosiglitazone group was observed. Furthermore, homeostasis model assessment index improvement was obtained only at 9 and 12 months (p < 0.05 and p < 0.01 respectively) compared with the baseline value in rosiglitazone group. Significant TC, LDL-C and Apo B improvement (p < 0.05 respectively) was present in glimepiride group after 12 months compared with the baseline values, and these variations were significant (p < 0.05) between groups. Of the 95 patients who completed the study, 8.5% of patients in glimepiride group and 12.5% of patients in rosiglitazone group had side-effects (p = not significant). Four patients had transient side-effects in glimepiride group and six patients in rosiglitazone group. Altogether, we did not have statistically significant changes in transaminases. CONCLUSIONS The rosiglitazone-metformin association significantly improve the long-term control of all insulin-resistance-related parameters in comparison with the glimepiride-metformin-treated group. On the other side, glimepiride treatment is associated to a slight improvement in cholesterolaemia, not observed in the rosiglitazone-treated patients.

Abstract
The peripheral obstructive artery disease (POAD) epidemiology raises some concerns about its continuously increased incidence in Western countries. The most part of the patients affected by POAD have systemic cardiovascular complications and die because of cardiac and cerebrovascular disorders. Thus the social cost of this disease is very high. A large part of risk factors for the POAD is well-known and they are reversible trough an efficacious life-style improvement (mainly physical activity increase and cigarette smoking habit cessation) and cardiovascular disease risk factors control (diabetes mellitus, hypercholesterolemia, blood hypertension). On the contrary, no much data are available as it regards efficacious therapies for clinically active disease. The only ones that have been adequately investigated and already available in the market are cilostazol (maybe useful only in more serious patients), and sulodexide (that could improve the pain free walking distance till the 75%). Further research is needed in order to develop new efficacious drugs for POAD treatment, but in the meantime it is necessary to recognise all POAD patients as soon as possible and to treat them adequately with the available therapies.

Abstract
Recently, two large randomised clinical trials compared the effects of standard and intensive lipid-lowering treatment (Pravastatin 40 mg vs. Atorvastatin 40 mg b.i.d.) on patient prognosis after acute coronary syndromes--the Pravastatin or Atorvastatin Evaluation and Infection Therapy (PROVE-IT), and on the atherosclerosis regression--the Reversing Atherosclerosis with Aggressive Lipid Lowering (REVERSAL). Undoubtedly, the event-rate reduction and the atherosclerosis regression associated to intensive hypocholesterolemic treatment in these studies are impressive, however we would like to highlight some methodological concerns raised by both trials, more clinically oriented than planned to give rigorous answers to the scientist. The main problems of both studies are that they compare the effects of statins with different pleiotropic and pharmacokinetic properties and that the metabolic disorders that affect the studied patients have not been clearly described. Moreover, it is unclear if the cardiovascular disease history length was similar in the two treatment groups as well as the length and dosage of statin treatment of the about 25% of patients taking statins before the enrollment. Waiting for studies comparing the effects of low and high dosages of the same statin or the high dosage of two similarly potent and rapid lipid-lowering effect (as for instance atorvastatin and rosuvastatin), prudence has to be applied in the interpretation (and even more in the application) of these large and expensive study results, that have yet only confirmed the relevance of a more intensive lipid-lowering treatment in all patients affected by atherosclerosis-based coronary syndromes.

Abstract
AIM The aim of this study was to evaluate and quantify the role of different risk factors in the long-term development of Type 2 diabetes mellitus in a rural Italian population. METHODS The Brisighella Heart Study (BHS; 1972-2003) is a prospective, population-based longitudinal epidemiological cohort involving 2939 randomly selected subjects, aged 14-84 years, resident in the rural Italian town of Brisighella. For this study, we randomly selected 1441 adult subjects representative of the Brisighella population; consecutively visited during three BHS surveys. A step-wise Cox regression analysis determined the prognostic significance of each independent risk factor for the development of Type 2 diabetes in the 8-year long follow-up. RESULTS Blood pressure, high-density lipoprotein cholesterol, triglycerides, physical activity, total energy intake, and drug treatment had no effect on the incidence of diabetes. Age was a significant predictor of Type 2 diabetes when inserted alone in the model (P = 0.007), but irrelevant when adjusted for baseline body mass index (BMI) and or fasting plasma glucose. Among these with impaired fasting glucose (IFG), the diabetes incidence/year was estimated to be 6.6% for men and 11.2% for women (P < 0.001). Basal glycaemia under 6.1 mmol/l were not significant long-term predictors of diabetes development, while higher basal glycaemia and each level BMI were. CONCLUSION Our findings confirm that IFG and BMI predict Type 2 diabetes development in our population. This should help to identify effective approaches to prevention.

Abstract
OBJECTIVE To describe the effect of Coenzyme Q10 (CoQ10) (added to either a fibrate, or polyunsaturated fatty acids (PUFA) or association of both) in patients affected by massive hypertriglyceridemia (MHTG) resistant to fibrates and PUFA. DESIGN Open, sequential, comparative intervention study. SETTING Specialised centres for dyslipidemia management. SUBJECTS Fifteen subjects (mean age: 45.1+/-12.5 years) affected by MHTG and hyporesponsive to either fibrates, or PUFA, or fibrates-PUFA association, and 15 age-matched subjects regularly responders to PUFA and fenofibrate treatment. INTERVENTIONS Treatment for periods of 6 weeks each with the following consecutive treatments: CoQ10 150 mg/day, PUFA 3000 mg/day, fenofibrate 200 mg/day, PUFA 3000 mg/day+fenofibrate 200 mg/day, PUFA 3000 mg/day+CoQ10 150 mg/day, fenofibrate 200 mg/day+CoQ10 150 mg/day, and finally, fenofibrate 200 mg/day+PUFA 3000 mg/day + CoQ10 150 mg/day. RESULTS CoQ10 supplementation did not improve any monitored parameter in the control group except for systolic and diastolic blood pressure, creatinine and Lp(a) plasma levels, both during fenofibrate and/or PUFA treatment. In MHTG group, CoQ10 supplementation significantly improved TG, TC, Lp(a), uric acid and blood pressure during fenofibrate treatment, but only Lp(a) and blood pressure during PUFA treatment. Fenofibrate appeared to have better effect on hsCRP and gamma-GT plasma levels than PUFA. No significant change was observed in any group and under any treatment in regards to homocysteinemia, PAI-1, or t-PA. CONCLUSION Even though the mechanism of action through which the effects were obtained is yet to be elucidated, adding CoQ10 to fenofibrate could improve the drug's efficacy in MHTG patients not responding to fenofibrate alone.
