Abstract
BACKGROUND AND AIM The objective of this cross-sectional study was to evaluate the degree of glycaemic control and the frequency of diabetic complications in Italian people with diabetes who were treated with continuous subcutaneous insulin infusion (CSII). METHODS AND RESULTS Questionnaires investigating the organisation of diabetes care centres, individuals' clinical and metabolic features and pump technology and its management were sent to adult and paediatric diabetes centres that use CSII for treatment in Italy. Information on standard clinical variables, demographic data and acute and chronic diabetic complications was derived from local clinical management systems. The sample consisted of 6623 people with diabetes, which was obtained from 93 centres. Of them, 98.8% had type 1 diabetes mellitus, 57.2% were female, 64% used a conventional insulin pump and 36% used a sensor-augmented insulin pump. The median glycated haemoglobin (HbA1c) level was 60 mmol/mol (7.6%). The HbA1c target (i.e. <58 mmol/mol for age <18 years and <53 mmol/mol for age >18 years) was achieved in 43.4% of paediatric and 23% of adult participants. Factors such as advanced pump functions, higher rate of sensor use, pregnancy in the year before the study and longer duration of diabetes were associated with lower HbA1c levels. The most common chronic complications occurring in diabetes were retinopathy, microalbuminuria and hypertension. In the year before the study, 5% of participants reported ≥1 episode of severe hypoglycaemic (SH) episodes (SH) and 2.6% reported ≥1 episode of ketoacidosis. CONCLUSIONS Advanced personal skills and use of sensor-based pump are associated with better metabolic control outcomes in Italian people with diabetes who were treated with CSII. The reduction in SH episodes confirms the positive effect of CSII on hypoglycaemia. CLINICAL TRIAL REGISTRATION NUMBER NCT 02620917 (ClinicalTrials.gov).

Abstract
BACKGROUND AND AIMS Diabetic women have a more adverse plasma lipid profile than men. Sex differences in dietary habits may play a role, but are little investigated. The study evaluates the quality of diet, adherence to the nutritional recommendations of the Diabetes and Nutrition Study Group and their relation with plasma lipid in men and women with diabetes. METHODS AND RESULTS We studied 2573 people, aged 50-75, enrolled in the TOSCA.IT study (clinicaltrials.gov; NCT00700856). Plasma lipids were measured centrally. Diet was assessed with a semi-quantitative food frequency questionnaire. Women had a more adverse plasma lipid profile than men. Women consumed significantly more legumes, vegetables, fruits, eggs, milk, vegetable oils, and added sugar, whereas men consumed more starchy foods, soft drinks and alcoholic beverages. This stands for a higher proportion (%) of energy intake from saturated fat and added sugar (12.0 ± 2.4 vs 11.5 ± 2.5 and 3.4 ± 3.2 vs 2.3 ± 3.2, P < 0.04), and a higher intake of fiber (11.2 ± 2.8 vs 10.4 ± 2.6 g/1000 Kcal/day) in women. Adherence to the recommendations for saturated fat and fiber consumption was associated with significantly lower LDL-cholesterol regardless of sex. Adherence to the recommendations for added sugars was associated with significantly lower triglycerides and higher HDL-cholesterol in men and women. CONCLUSIONS Men and women with diabetes show significant differences in adherence to nutritional recommendations, but sex differences in plasma lipid profile are unlikely to be explained by nutritional factors. Adherence to the nutritional recommendations is associated with a better plasma lipid profile regardless of sex, thus reinforcing the importance of substituting saturated for unsaturated fat sources, increasing fiber and reducing added sugar intake.

Abstract
PURPOSE The optimal macronutrient composition of the diet for the management of type 2 diabetes is debated, particularly with regard to the ideal proportion of fat and carbohydrates. The aim of the study was to explore the association of different proportions of fat and carbohydrates of the diet-within the ranges recommended by different guidelines-with metabolic risk factors. METHODS We studied 1785 people with type 2 diabetes, aged 50-75, enrolled in the TOSCA.IT Study. Dietary habits were assessed using a validated food-frequency questionnaire (EPIC). Anthropometry, fasting lipids, HbA1c and C-reactive protein (CRP) were measured. RESULTS Increasing fat intake from <25 to ≥35 % is associated with a significant increase in LDL-cholesterol, triglycerides, HbA1c and CRP (p < 0.05). Increasing carbohydrates intake from <45 to ≥60 % is associated with significantly lower triglycerides, HbA1c and CRP (p < 0.05). A fiber intake ≥15 g/1000 kcal is associated with a better plasma lipids profile and lower HbA1c and CRP than lower fiber consumption. A consumption of added sugars of ≥10 % of the energy intake is associated with a more adverse plasma lipids profile and higher CRP than lower intake. CONCLUSIONS In people with type 2 diabetes, variations in the proportion of fat and carbohydrates of the diet, within the relatively narrow ranges recommended by different nutritional guidelines, significantly impact on the metabolic profile and markers of low-grade inflammation. The data support the potential for reducing the intake of fat and added sugars, preferring complex, slowly absorbable, carbohydrates.

Abstract
The DAWN (Diabetes Attitudes, Wishes and Needs) study is a survey promoted by the International Diabetes Federation to recognize the perceptions and attitudes of people suffering from diabetes mellitus. In this context, we evaluated the quality of life of Italian and immigrant women with gestational diabetes mellitus (GDM). Information was gathered using a structured questionnaire for patients' self-compilation. In a 3-month period, a 51-item questionnaire was submitted to 198 Italians and 88 immigrants (from 27 different foreign nationalities). Italian women were older and had higher education than the immigrants. 60% of the Italians and 38% of the immigrants had a family history of diabetes mellitus. In both groups, the diagnosis of GDM caused anxiety; one-third of women feared their child could contract diabetes at delivery and/or have congenital malformations. Some women had trouble in following treatment regimens: the major concern being dietary advice and blood glucose testing. Most women were satisfied (34%) or highly satisfied (60%) with the quality of care, although the degree of cooperation between diabetes specialists and gynaecologists was considered sometimes unsatisfactory. In order to optimize maternal and foetal outcomes, educational projects and improved communication between patients and the healthcare provider team are recommended.

Abstract
AIM The best way to treat pregnant patients who have type 1 diabetes is still unclear. For this reason, the present study compared metabolic control and maternal-fetal outcomes in patients treated with continuous subcutaneous infusions of rapid-acting insulin analogues (CSII) or with insulin glargine and multiple daily injections of rapid-acting insulin analogues (glargine-MDI). METHODS This retrospective multicentre study involved 144 women with type 1 diabetes, 100 of whom were using CSII and 44 glargine-MDI. Outcomes analyzed were metabolic control, diabetes complications, pregnancy outcome, perinatal morbidity and mortality, and fetal malformations. RESULTS The two groups were comparable for age, prepregnancy BMI, primiparous rate and diabetes complications, although patients using CSII had longer duration of diabetes (P=0.03) and higher White classifications (P=0.04). In both groups, metabolic control improved during pregnancy, but good control was reached earlier among patients using CSII. At parturition, patients using CSII had lower HbA(1c) (6.2±0.7% vs 6.5±0.8%; P=0.02) and required less insulin (P<0.01). Weight gain was similar in both groups, and maternal-fetal outcomes did not differ. CONCLUSION In pregnant patients with type 1 diabetes, MDI and CSII are equivalent in terms of metabolic control and fetal-maternal outcomes, although patients using CSII achieved good control earlier and with less insulin.

Abstract
Some studies have shown that fetal outcome observed in patients using insulin lispro is much the same as in pregnant women using regular insulin. This study aims to analyze the Italian data emerging from a multinational, multicenter, retrospective study on mothers with type 1 diabetes mellitus before pregnancy, comparing those treated with insulin lispro for at least 3 months before and 3 months after conception with those treated with regular insulin. The data collected on pregnant women with diabetes attending 15 Italian centers from 1998 to 2001 included: HbA1c at conception and during the first and third trimesters, frequency of severe hypoglycemic episodes, spontaneous abortions, mode and time of delivery, fetal malformations and mortality. Seventy-two diabetic pregnancies treated with lispro and 298 treated with regular insulin were analyzed, revealing a trend towards fewer hypoglycemic episodes in the former, who also had a significantly greater reduction in HbA1c during the first trimester. The rate of congenital malformations was similar in the offspring of the two groups of women treated with insulin lispro or regular insulin. These findings suggest that insulin lispro could be useful for the treatment of hyperglycemia in type 1 diabetic pregnant women.

Abstract
OBJECTIVE The aim of this study was to use the Eating Attitudes Test-26 (EAT-26) as a screening instrument on a specific population with a marked prevalence of binge eating disorder (BED) and eating disorder not otherwise specified (EDNOS). The EAT-26 questionnaire was used in order to identify the high-risk subjects for referral to clinical evaluation. METHOD EAT-26 was administered to 845 subjects who, for the first time, came to the Nutritional Medicine Service looking for a diet between January 1999 and December 2002. From this initial sample, subsequently, 250 subjects were randomly selected and administered a semistructured clinical interview for DSM-IV (SCID I, version 2.0). RESULTS Discriminant analysis provided a cutoff value of EAT-26=11. Logistic regression analysis indicated high Dieting (D) or Bulimia (B) subscale scores as a risk factor of EDNOS or bulimia nervosa (BN) cases, respectively; on the other hand, a high Oral Control (O) subscale score represented a protecting factor for BED cases. CONCLUSION Our study tried to assess the usefulness of EAT-26 as a screening instrument for obese patients attending a Medical Nutritional Service. Results from this study suggest that a cutoff score of 11, lower than that indicated in the literature, improves the diagnostic accuracy of the EAT-26 in a high-risk setting regarding sensibility level (68.1%) and leading to a reduction of the false negative rate (31.9%).

Abstract
UNLABELLED Over 1 year, a survey on contraception and obstetric history was performed on a cohort of 667 Caucasian fertile diabetic women (446, type 1 and 201, type 2) living in Italy. RESULTS Of these women, 30.4% used hormonal contraceptives, 12.0% intra-uterine device (IUD), 10.7% declared they used no contraception, 47.0% only utilised barrier and/or natural methods. However, irrespective of their previous contraceptive strategy, 7.2% of all the studied population was surgically sterilized during caesarean section. HORMONAL CONTRACEPTION Of these women, 60.4% was prescribed by a gynaecologist, 11.2% by a diabetologist, 15% by both of them and 13.4% by others. The proportion using oral contraception was similar among types 1 and 2 women (29.4% versus 27.8%, chi(2) = ns). SMOKING HABITS Of women taking hormonal contraception, 30.0% were smokers. EDUCATIONAL LEVEL University graduates (37.1%), high school leaves (32.2%), secondary school (28.2%) and primary school leaves (15.5%) used oral contraceptives (OC). OBSTETRIC HISTORY The mean number of deliveries was 1.14 +/- 1.1, of miscarriages was 1.3 +/- 0.7 and of induced abortions 0.17 +/- 0.5. Planning of at least one pregnancy was reported in 29.4% of patients.

Abstract
AIMS/HYPOTHESIS Oxidative stress plays an important role in diabetic vascular complications. It has been shown that an imbalance in the ratio of nitric oxide: superoxide anion, because of a prevalence of superoxide anion, leads to an alteration in vascular reactivity. In this condition peroxynitrite production, resulting from the reaction between nitric oxide and superoxide, could increase. Peroxynitrite is responsible for nitration of tyrosine residues in proteins. Therefore, the presence of nitrotyrosine in plasma proteins is considered indirect evidence of peroxynitrite production. The aim of this study was to demonstrate the presence of nitrotyrosine in the plasma of patients with Type II (non-insulin-dependent) diabetes mellitus and to correlate its concentrations with the plasma concentrations of glucose and antioxidant defenses. METHODS A total of 40 Type II diabetic patients and 35 healthy subjects were enrolled, and glycaemia, plasma nitrotyrosine, total antioxidant parameter and glycated haemoglobin were measured. Nitrotyrosine was detected by ELISA with a detection limit of 10 nmol/l. RESULTS Nitrotyrosine was found in the plasma of all diabetic patients (means +/- SD = 0.251 +/- 0.141 micromol/l), whereas it was not detectable in the plasma of healthy control subjects. Nitrotyrosine plasma values were correlated with plasma glucose concentrations (r = 0.38, p < 0.02) but not with total antioxidant parameter or glycated haemoglobin. Total antioxidant parameter was reduced in diabetic patients (p < 0.01). CONCLUSIONS The presence of nitrotyrosine in the plasma of diabetic patients indicates that peroxynitrite is generated in diabetes, suggesting a possible involvement of peroxynitrite in the development of diabetic complications.

Abstract
BACKGROUND Oxidative stress and thrombosis have been reported to be increased in diabetic patients and involved in the pathogenesis of cardiovascular complications. It has been demonstrated in diabetic patients that consumption of a meal is accompanied by the generation of an oxidative stress and of a hypercoagulable state. It is well recognized that red wine shows antithrombotic activity and that its ingestion increases plasma antioxidant capacity in man. In this study the possibility that red wine consumption may reduce the oxidative stress and thrombosis produced postprandially in diabetic patients has been evaluated. SUBJECTS AND METHODS Twenty type 2 diabetic patients were studied during fasting consumption of 300 mL of red wine, or during a meal accompanied, or not, by red wine ingestion. RESULTS Plasma glucose, insulin, triglycerides, total plasma radical-trapping capacity, activated factor VII and prothrombin fragments 1 + 2 were measured in basal state and at 60, 120 and 180 min after the start of each experiment. Low-density lipoprotein (LDL) oxidation was also evaluated at baseline and after 120 min Plasma glucose, insulin, triglycerides and LDL oxidation significantly increased, while the total plasma radical-trapping parameter significantly decreased during the meal test. Consumption of red wine in the fasting state significantly increased total plasma radical-trapping parameter activity, while wine ingestion with a meal counterbalanced the decrease of total plasma radical-trapping parameter and the increase of LDL oxidation. Meal consumption induced an increase in plasma prothrombin fragments 1 + 2 and activated factor VII in diabetic patients. Wine ingestion with the meal significantly reduced the production of both prothrombin fragments 1 + 2 and activated factor VII. Fasting consumption of red wine alone did not show effects on coagulation or LDL oxidation. CONCLUSION This finding confirms that in the absorptive phase free radicals are produced in diabetic patients, which reduce serum antioxidant defences, increase LDL oxidation and activate the coagulation system. Red wine consumption during a meal significantly preserves plasma antioxidant defences and reduces both LDL oxidation and thrombotic activation. The consumption of a moderate amount of red wine during meals may have a beneficial effect in the prevention of cardiovascular disease in diabetic patients.

Abstract
Oxidative stress and its contribution to low-density lipoprotein (LDL) oxidation have been implicated in the pathogenesis of vascular diabetic complications. However, the relationship between hyperglycemia, hyperinsulinemia, hyperlipidemia, and oxidative stress is still debated. If plasma glucose and/or insulin and/or lipid are some of the most important determinants of oxidative stress in diabetes, then their typical postprandial elevations in diabetes would be expected to favor oxidative stress and LDL oxidation. To test this hypothesis, in type 2 diabetic patients, we evaluated the effects of two different standard meals designed to produce different levels of postprandial hyperglycemia on the plasma oxidative status and LDL oxidation. The meals were administered in randomized order to each of 10 type 2 diabetic patients. Blood samples were collected at baseline and 60 and 120 minutes after the meals. In every sample, plasma levels of glucose, insulin, cholesterol, triglycerides, nonesterified fatty acids (NEFAs), malondialdehyde (MDA), and the total radical-trapping antioxidant parameter (TRAP) were measured. LDL susceptibility to oxidation was evaluated at baseline and after 120 minutes. Plasma glucose, insulin, triglycerides, and MDA increased and NEFAs and TRAP significantly decreased after either meal. The variations in plasma glucose, MDA, and TRAP were significantly greater and LDL was more susceptible to oxidation after the meal that produced a significantly higher degree of hyperglycemia. These results suggest that postprandial hyperglycemia may contribute to oxidative stress in diabetic patients, providing a mechanistic link between hyperglycemia and diabetic vascular disease.

Abstract
Recent studies show that in diabetic subjects an increase of plasma fibrinogen concentration is associated with a high risk of cardiovascular complications. Environmental and genetic factors contribute to the plasma fibrinogen concentration. Several studies indicate a relation between the polymorphism in the 5' region of the beta-fibrinogen gene and plasma protein concentrations and in diabetes the possible influence of hyperglycaemia on fibrinogen is still debated. In this study we investigated these relations. Hind III polymorphism was evaluated by a polymerase chain reaction-technique. On the basis of the observed allelic combination of fibrinogen beta-gene polymorphism and the existence of poor metabolic control (glycated haemoglobin > or = 7.5%), 50 Type II diabetic patients were selected. They were divided into three groups according to their beta-gene polymorphism (alpha1alpha1: n = 20, alpha1alpha2: n = 15, alpha2alpha2: n = 15) and then intensive insulin therapy was started. After 3 months of intensive treatment, the improvement in glycaemic control was equivalent, in terms of glycated haemoglobin, in all the three groups. A fibrinogen reduction was observed in alpha1alpha2 and alpha2alpha2 but not in alpha1alpha1 subjects. These results underline a possible relation between fibrinogen genotypes and glycaemic control in determining plasma fibrinogen concentrations in diabetic patients.

Abstract
OBJECTIVE Free radical production has been reported to be increased in diabetic patients and to be involved in the pathogenesis of diabetic complications. In this study, a standardized meal was administered to 10 type 2 diabetic patients and 10 healthy matched normal subjects to evaluate its effects on plasma oxidative stress generation. RESEARCH DESIGN AND METHODS In diabetic patients, at baseline and after the meal, plasma malondialdehyde (MDA), vitamin C, protein SH groups, uric acid, vitamin E, and total plasma radical-trapping parameter, which evaluates plasma antioxidant capacity due to known and unknown antioxidants present in the plasma as well as their mutual cooperation, were measured. RESULTS After the meal, plasma MDA and vitamin C increased, while protein SH groups, uric acid, vitamin E, and total plasma radical-trapping parameter decreased more significantly in the diabetic subjects than in control subjects. CONCLUSIONS This finding shows that in the absorptive phase, free radicals are produced in diabetic patients. Since plasma glucose, but not insulin, rose significantly more in diabetic subjects than in control subjects, hyperglycemia may play an important role in the generation of postprandial oxidative stress in diabetic patients.

Abstract
BACKGROUND Free radical production has been reported to be increased in patients with diabetes mellitus, and it has been suggested that hyperglycaemia may directly contribute to the generation of oxidative stress. The aim of the present study was to evaluate the effects of an acute increase in glycaemia on plasma antioxidant defences. RESULTS During the oral glucose tolerance test (OGTT), plasma concentration of protein-bound sulphydryl (SH) groups, vitamin C, vitamin E and uric acid significantly decreased in normal as well as non-insulin-dependent diabetes mellitus (NIDDM) subjects. Total plasma radical-trapping activity, which evaluates plasma antioxidant capacity due to known and unknown antioxidants present in the plasma as well as their mutual co-operation, was also significantly reduced. CONCLUSION This finding supports the hypothesis that hyperglycaemia may, even acutely, induce an oxidative stress.

Abstract
ICAM-1 is one of the most important intercellular adhesion molecules involved in atherogenesis. Previous studies reported increased circulating ICAM-1 plasma levels in NIDDM patients with or without vascular complications. It has been suggested that an acute increase of plasma glucose may produce an oxidative stress in man, and in vitro studies have demonstrated that high glucose and free radicals induce cellular expression of ICAM-1. In this study, three different experiments were performed in nine NIDDM patients and in seven matched healthy controls: oral glucose tolerance test, antioxidant glutathione i.v. administration for two h, oral glucose tolerance test plus glutathione i.v. administration. Blood samples were drawn at -15 min and every 30 min from 0 to 180 min. During the oral glucose tolerance test, circulating ICAM-1 plasma levels significantly increased in both diabetic and normal subjects. Glutathione administration during the oral glucose tolerance test abolished this phenomenon. Glutathione administered alone significantly decreased circulating ICAM-1 plasma levels in diabetic patients, while no effect was observed in the normal subjects. These data suggest that hyperglycemia may induce an increase of circulating ICAM-1 plasma levels through an oxidative stress, and that the antioxidant glutathione counterbalances this effect. These data support the hypothesis of a causal relationship linking hyperglycemia, oxidative stress and atherogenesis in diabetes mellitus.

Abstract
OBJECTIVE To explore the hypothesis that a relationship exists between free radical activity and abnormalities in hemostasis in NIDDM. RESEARCH DESIGN AND METHODS The use of the total radical-trapping antioxidant parameter (TRAP) has very recently been proposed to explore the antioxidant property of a plasma and their mutual cooperation. In the present study, TRAP, vitamin E, vitamin C, vitamin A, uric acid, protein-bound SH (thiol) groups, fibrinogen, prothrombin fragments F1 + 2, and D-dimer have been evaluated in 46 NIDDM patients and 47 healthy matched control subjects. RESULTS In NIDDM patients, TRAP, vitamin A, SH groups, and uric acid were significantly reduced, whereas the level of vitamin E was significantly increased. Vitamin C was similar in the two groups. Fibrinogen, prothrombin fragment 1 + 2, and D-dimer were increased in diabetic patients. TRAP, but no single other antioxidant, had a strong inverse association with fibrinogen, prothrombin fragment 1 + 2, and D-dimer. CONCLUSIONS These findings are consistent with the hypothesis that oxidative stress may condition coagulation activation in diabetics. However, the data suggest that it is the total antioxidant capacity rather than any single plasma antioxidant that is the most relevant parameter.

Abstract
OBJECTIVE The existence of an oxidative stress in diabetes is still debated. This is largely due to the lack of good tools to assay the level of oxidative stress. The use of total radical-trapping antioxidant parameter (TRAP) has recently been proposed to explore the antioxidant property of a plasma sample. TRAP may be either directly measured by a fluorescence-based method (TRAPm) or calculated (TRAPc) by a mathematical formula, taking into account the serum levels of four natural antioxidants: protein-bound SH (thiol) groups, uric acid, vitamin E, and vitamin C. The difference between TRAPm and TRAPc is due to antioxidants, which are still unidentified, and to the possible synergism among the antioxidants. RESEARCH DESIGN AND METHODS In this study, we evaluated malondialdehyde (MDA), TRAPm, TRAPc, protein-bound SH groups, uric acid, vitamin E, and vitamin C in 40 NIDDM patients and 40 matched normal control subjects. RESULTS TRAPm and TRAPc were significantly lower in diabetic patients. A good correlation between TRAPm and TRAPc was found in both NIDDM patients (r = 0.68, P < 0.0001) and control subjects (r = 0.74, P < 0.0001). Protein-bound SH groups and uric acid were significantly lower in diabetic subjects, while MDA and vitamin E level were significantly higher. After correction for serum triglycerides (MDA) and cholesterol (vitamin E), MDA lost significance, while vitamin E did not. Vitamin C was not different in the two groups. CONCLUSIONS These data show decreased TRAP levels in NIDDM patients, suggesting the existence of lower antioxidant defenses in diabetes. The decrease appears to be due to various antioxidants, some of them not yet clearly defined. TRAP may represent a more reliable estimation of serum antioxidant capacity than the measurement of each known antioxidants. The correlation found between TRAPm and TRAPc values suggests that TRAPc, easier to measure than TRAPm, might be adequately reliable for routine assessment of oxidative stress in diabetic patients.

Abstract
It has been previously demonstrated that hyperglycaemia activates haemostasis; diabetes mellitus is considered a thrombosis-prone state. Acarbose, by inhibiting dietary carbohydrate absorption, reduces post-meal hyperglycaemia. In this study we evaluated the effect of post-meal hyperglycaemia on two markers of coagulation activation: prothrombin fragments 1 + 2 and D-dimer. Seventeen non-insulin-dependent diabetic patients maintained on diet therapy alone were randomly assigned to receive- with a cross-over study design-acarbose (100 mg orally) or placebo before a standard meal. Blood samples for measurement of plasma glucose, insulin, prothrombin fragments 1 + 2 and D-dimer were drawn at 0, 60, 120 and 240 min. After both placebo and acarbose, hyperglycaemia and hyperinsulinaemia which followed a standard meal were accompanied by a significant increase of plasma concentration of prothrombin fragments 1 + 2 and D-dimer in comparison to their baseline values. Acarbose administration significantly reduced the rise of glucose, insulin, prothrombin fragments 1 + 2 and D-dimer from 0 to 240 min in comparison to placebo. We conclude that post-meal hyperglycaemia, at the level reached by many diabetic patients on diet therapy alone, induces a coagulation activation. Acarbose, by decreasing post-meal hyperglycaemia, may be useful in reducing meal-induced activation of haemostasis in diabetic patients.

Abstract
Diabetes is characterized by the existence of a thrombosis-prone condition, possibly related to hyperglycemia. However, the mechanism linking hyperglycemia to the activation of the coagulation cascade is still unclear. It has been recently suggested that diabetes is accompanied by increased oxidative stress. In this work, the possibility that oxidative stress may be involved in the hyperglycemia-induced coagulation activation has been evaluated. Prothrombin fragment 1 + 2 (F1 + 2), which represents a reliable marker of the amount of thrombin released in the circulation, has been chosen for studying thrombin formation in vivo. In nine type II diabetic patients and in seven healthy control subjects, matched for age and body mass index, three different experiments were performed: oral glucose tolerance test (OGTT), intravenous antioxidant glutathione (GSH) administration for 2 h, and OGTT plus intravenous GSH administration. Samples were drawn at -15 min and every 30 min from 0 to 180 min. During the OGTT, F1 + 2 significantly increased in both diabetic and healthy subjects. GSH administration during OGTT normalized this phenomenon. GSH administration alone significantly decreased F1 + 2 in diabetic patients, while no effect was observed in the normal subjects. These data suggest that hyperglycemia may induce thrombin activation, possibly inducing an oxidative stress, and that antioxidant GSH may counterbalance this effect.

Abstract
Nicotinamide was shown to prevent damage and to stimulate B cell regeneration in experimental diabetes but in humans results are still controversial. To ascertain if long term nicotinamide treatment can induce and/or prolong remission of the disease, 21 type 1 (insulin-dependent) recently diagnosed subjects entered a controlled study and randomly divided in two groups comparable for age, genetic and immunologic patterns: group 1 (11 subjects) received insulin and nicotinamide (3 g/day for 1 year) and group 2 (10 subjects) insulin alone. Bimonthly insulin requirement and HbA1c, and every 6 months C-peptide response to glucagon were registered for 2 years. No significant difference was observed between the two groups in the monitored parameters, including rates of clinical remission, along this time period. In conclusion nicotinamide, when employed after the clinical onset of the disease, has no additional effect on natural history of newly diagnosed type 1 diabetes mellitus, besides results obtained by insulin alone.

Abstract
Atherosclerotic manifestations are more common and precocious in diabetics than in the general population. Due to the increased cardiovascular risk, a primary or secondary (to diabetes mellitus) lipoprotein disorder in diabetics has to be carefully considered. 27 diabetics (15 NIDDM and 12 IDDM) with dyslipidemia (14 type IV, 8 type IIa and 5 type IIb) were divided in 3 groups and treated with 3 different hypolipemic drugs (Group A: pantethine 600 mg/day; Group B: acipimox 500 mg/day; Group C: bezafibrate 600 mg/day) to test their efficacy and acceptancy. Body weight, Hb A1-c, serum lipoproteins have been measured before and during the 6 months treatment. A significant variation of lipidemic pattern was observed in Group C: a decrease of cholesterol (-20%), triglycerides (-40%), LDL (-24.4%) and apo B (-26.8%) with an increase of HDL (+23.6%). Pantethine and acipimox were more effective on triglycerides (-37.7% and -23.3% respectively). Cardiovascular risk (CT tot/CT HDL) was significantly reduced with acipimox and normalized with bezafibrate.

Abstract
Physical exercise is a well known provocative test for early renal abnormalities detection in diabetes mellitus. Aim of our study was to evaluate the effect of daily activity and physical exercise on albumin excretion rate (AER) in 2 groups of albustix negative type I diabetics (IDDM). In group I of 76 patients aged 7-58 years, AER measured in 24 h urine (14.1 +/- 1.7 micrograms/min) and overnight urine (11.1 +/- 1.7 micrograms/min) was similar. A significant correlation was found between AER values obtained from the two urine collection procedures (r = 0.55; p less than 0.001). In group 2 of 37 patients aged 7-48 years and in 25 matched controls, the effect of physical exercise on AER was evaluated comparing overnight urine and post-exercise urine collection. AER increased significantly in IDDM after exercise. In conclusion our results show that 1) AER is not affected by daily activity; 2) physical exercise is a usefull provocative test to detect early renal abnormalities.

Abstract
1. Baroreceptor sensitivity and vascular reactivity to noradrenaline were assessed in patients with essential hypertension chronically treated with diuretics during treatment and 6-8 weeks after its withdrawal. 2. Stopping diuretics was followed by an increase in mean arterial blood pressure and vascular reactivity, while baroreceptor sensitivity decreased. 3. Baroreceptor sensitivity during treatment correlated directly with the time during which patients remained normotensive after stopping diuretics. 4. An inverse correlation was found between vascular reactivity and baroreceptor sensitivity after diuretic withdrawal and between the patients' age and baroreceptor sensitivity during diuretic therapy. 5. We conclude that the impairment of baroreceptor sensitivity after stopping diuretic therapy could result in an enhanced vascular response to noradrenaline, and a sensitive baroreflex could contribute to the control of blood pressure during diuretic treatment and buffers the return of high blood pressure when diuretics are stopped.

Abstract
The effect of chronic treatment with indapamide on blood pressure (BP), baroreceptor sensitivity (BRS) and vascular reactivity (VR) were investigated in 10 patients with essential hypertension. After 3 months of therapy with indapamide 2.5 mg/d the mean arterial pressure (MAP) had decreased from 135 +/- 6 to 112 +/- 2 mmHg (p less than 0.001); the heart rate (HR) had not changed, VR had decreased from 6.1 +/- 1.2 to 4.8 +/- 1.8 (pg . min . kg)-1 (p less than 0.05), and BRS had increased from 8.3 +/- 3.7 to 12.2 +/- 5.3 ms/mmHg (p less than 0.005), with a leftshift of the relationship between BP and heart period. An inverse correlation was found between the pre-treatment systolic blood pressure and the change in baroreceptor sensitivity after indapamide (r = 0.59; p less than 0.05). In conclusion, chronic treatment with indapamide enhances BRS and resets the reflex. The resetting may account for the lack of tachycardia at rest observed after treatment with indapamide. The mechanism by which indapamide interferes with the baroreceptor reflex requires further investigations.
