insulin-glargine and Diabetic-Angiopathies

Patients with type 2 diabetes mellitus (T2DM) have an increased risk of cardiovascular disease (CVD). Unfortunately, several potential barriers exist for CVD risk management in diabetes, including the need for significant lifestyle changes, potential problems with hypoglycemia, weight gain, injection tolerability, treatment complexity with current diabetes therapies and other, unmodifiable factors. Improving glycemic control may impact CVD risk. Treatment of T2DM usually starts with lifestyle changes such as diet and exercise. When these become insufficient, pharmacotherapy is required. Various oral antidiabetic drugs (OADs) are available that reduce hyperglycemia. The first line of therapy is usually metformin, since it does not increase weight and seems to have a beneficial effect on CVD mortality and risk factors. As T2DM progresses, insulin treatment becomes necessary for the majority of patients. The last few years have seen the development of long-acting, rapid-acting, and premixed insulin analog formulations. The treat-to-target algorithms of recent studies combining OADs plus insulin analogs have demonstrated that patients can reach glycemic treatment targets with low risk of hypoglycemia, greater convenience, and--with some analogs--limited weight gain vs conventional insulins. These factors may possibly have a positive influence on CVD risk. Future studies will hopefully elucidate the benefits of this approach.

Insulin glargine is an analogue of human insulin that is modified to provide a consistent level of plasma insulin over a long duration. Pharmacokinetic and pharmacodynamic studies show that a single injection of insulin glargine leads to a smooth 24-hour time-action profile with no undesirable pronounced peaks of activity. In clinical trials, this profile has been associated with at least equivalent, if not better, glycemic control than other traditional basal insulins and a significantly lower rate of overall and nocturnal hypoglycemia. The convenience of a once-daily injection, a lack of need for resuspension (insulin glargine is a clear solution when injected), and lower rates of hypoglycemia should translate into improvements in patient treatment satisfaction. This review appraises the evidence for the view that insulin glargine represents an advance in basal insulin therapy for both type 1 and type 2 diabetes patients.

The role of metabolic control following acute myocardial infarction, (AMI) is still subject of study to date. The only study performed in diabetic patients with an AMI is the DIGAMI which demonstrated that endovenous insulin therapy in the acute phase, followed by multiple subcutaneous administrations of insulin therapy in the follow-up, was able to obtain not only a better metabolic control in both the acute phase and in the follow-up, but also a better survival only in the follow-up. Even if this latter fact is disappointing, endovenous insulin infusion seems to be the best approach to effectively contrast the metabolic events secondary to hyperglycemia which accompany AMI. From the DIGAMI study derives the indication of multiple insulin injections in diabetic patients having survived an AMI, even if doubt still exists as to whether it is the insulin therapy in itself or rather the metabolic compensation obtained that is responsible for a better survival rate. There is no controversy regarding the use of multiple (3 but above all 4/day) subcutaneous rapid insulin administrations at meal time and retard insulin administrations at bed time. Over the last few years ultrarapid insulin has become available as well the newcomer glargine, a retard insulin, which presents a homogeneous 24 hour release pattern. These insulin forms, obtained by genetic engineering, allow for a 4 daily dose administration, ultrarapid at meal times and glargine once daily, which mimic a more physiological insulin secretion and as such probably render them more efficacious. When oral drugs are opted for, it is imperative to have acquaintance with their half-lives, bonding properties with K(+)(ATP) channels, the antioxidant and antithromobophylic properties. It is necessary to modulate their use considering the glycemic daily rhythm in diabetics (glycemia tending to be high in the early morning and low in the evening). In order to obtain an optimal metabolic control it is essential to have the patient perform a glycemia level self-assessment by means of portable measuring instruments which employ instantaneous reactive strips. Self-assessment is imperative for the prevention of hypoglycemic episodes considered particularly dangerous in diabetic patients with coronary heart disease, even if studies which have demonstrated and documented this danger do not exist.

In the Outcome Reduction with an Initial Glargine Intervention (ORIGIN) trial (Clinicaltrials.gov: NCT000069784), titrated doses of basal insulin glargine targeting fasting normoglycaemia had a neutral effect on cardiovascular outcomes. The dose of insulin required to achieve normoglycaemia provides a unique measurement of each individual's resistance to insulin's action, and was therefore used to examine the link between insulin resistance and cardiovascular outcomes.. Self-titration of insulin doses targeting a fasting plasma glucose ≤5.3 mmoL/L (95 mg/dL) was promoted at every visit and cardiovascular and other serious health outcomes were ascertained. All analyses were restricted to participants allocated to insulin glargine, who added it to lifestyle or 1 glucose-lowering oral agent at randomization. Normoglycaemia was defined as a fasting plasma glucose <5.6 mmol/L and HbA1c <6% at the 2-year visit. The median of the natural logarithm of insulin doses (expressed per kg of fat-free mass), recorded at every visit from randomization until either the penultimate visit or the first occurrence of a cardiovascular outcome, was analysed.. Higher median insulin doses did not reflect incident cardiovascular events overall or in the subset that achieved normoglycaemia. When the dose taken before a cardiovascular event or the penultimate visit was analysed, the adjusted hazard of the composite of cardiovascular death, myocardial infarction or stroke was 0.94 (95% CI 0.88, 1.00) per unit higher dose overall, and 0.91 (95% CI 0.81, 1.01) in the normoglycaemic subset.. Insulin resistance may not promote cardiovascular outcomes in individuals with dysglycaemia.

Hypoglycemia is a barrier to the achievement of glycemic targets and limits the beneficial effects of improved glucose control on cardiovascular outcomes in type 2 diabetes (T2D). Circulating endothelial progenitor cells (EPCs) participate in cardiovascular homeostasis and predict future cardiovascular events. Therefore, we herein analyzed the association between occurrence of hypoglycemia and EPC changes in T2D patients after optimization of glucose control with basal insulin therapy.. In the NCT00699686 trial, 42 T2D insulin-naïve patients received a 3 + 3-month cross-over therapy with glargine and detemir. There were 43 minor and 2 severe hypoglycemic episodes in 19 patients (45.2 %, 0.54 episodes/patient/year). Changes in EPCs were analyzed in relation to the occurrence of hypoglycemia during the trial.. Patients with hypoglycemia had a higher final HbA1c at 6 months than patients without, although absolute HbA1c changes were not significantly different. Though PCs increased at study end, in patients experiencing at least 1 hypoglycemic episode, the changes in CD34(+), CD133(+) progenitor cells and CD34(+)KDR(+) EPCs were significantly lower than the respective changes in patients without incident hypoglycemia, even after correcting for confounders. During treatment with detemir, which induced >twofold less hypoglycemia than glargine, CD34(+)KDR(+) EPCs increased significantly more than during treatment with glargine.. In naïve T2D patients initiating basal insulin, hypoglycemia prevents the increase in vasculoprotective PCs. Clinically, these data strengthen the importance of avoiding hypoglycemia to improve cardiovascular outcomes during the treatment of T2D.

Glycemic variability may contribute to adverse medical outcomes of type 2 diabetes, but prior therapies have had limited success in controlling glycemic fluctuations, and the hypothesis has not been adequately tested.. People with insulin-requiring type 2 diabetes and high cardiovascular risk were enrolled during a run-in period on basal-bolus insulin (BBI), and 102 were randomized to continued BBI or to basal insulin with a prandial GLP-1 receptor agonist (GLIPULIN) group, each seeking to maintain HbA(1c) levels between 6.7% and 7.3% (50-56 mmol/mol) for 6 months. The primary outcome measure was glycemic variability assessed by continuous glucose monitoring; other measures were HbA(1c), weight, circulating markers of inflammation and cardiovascular risk, albuminuria, and electrocardiographic patterns assessed by Holter monitoring.. At randomization, the mean age of the population was 62 years, median duration of diabetes 15 years, mean BMI 34 kg/m(2), and mean HbA(1c) 7.9% (63 mmol/mol). Thirty-three percent had a prior cardiovascular event, 18% had microalbuminuria, and 3% had macroalbuminuria. At baseline, the continuous glucose monitoring coefficient of variation for glucose levels was similar in both groups.. FLAT-SUGAR is a proof-of-concept study testing whether, in a population of individuals with type 2 diabetes and high cardiovascular risk, the GLIPULIN regimen can limit glycemic variability more effectively than BBI, reduce levels of cardiovascular risk markers, and favorably alter albuminuria and electrocardiographic patterns. We successfully randomized a population that has sufficient power to answer the primary question, address several secondary ones, and complete the protocol as designed.

Basal and bolus insulin therapy is required for strict blood control in diabetic patients, which could lead to prevention of vascular complications in diabetes. However, the optimal combination regimen is not well established.. Fifty-nine diabetic patients (49 type 1 and 10 type 2; 52.9 ± 13.3 years old) whose blood glucose levels were uncontrolled (HbA1c  > 6.2%) by combination treatment of basal insulin glargine with multiple daily pre-meal injections of bolus short-acting insulin [aspart (n = 19), lispro (n = 37) and regular human insulin (n = 3)] for at least 8 weeks were enrolled in this study. We examined whether glycaemic control and vascular injury were improved by replacement of short-acting insulin with glulisine. Patient satisfaction was assessed with Diabetes Treatment Satisfaction Questionnaire.. Although bolus and basal insulin doses were almost unchanged before and after replacement therapy, switching to glulisine insulin for 24 weeks significantly decreased level of HbA1c , advanced glycation end products (AGEs), soluble receptor for AGEs (sRAGE), monocyte chemoattractant protein-1 (MCP-1) and urinary albumin excretion. In multiple stepwise regression analysis, change in MCP-1 values from baseline (ΔMCP-1) was a sole determinant of log urinary albumin excretion. ΔAGEs and ΔsRAGE were independently correlated with each other. The relationship between ΔMCP-1 and ΔsRAGE was marginally significant (p = 0.05). Replacement of short-acting insulin by glulisine significantly increased Diabetes Treatment Satisfaction Questionnaire scores.. Our present study suggests that combination therapy of glargine with multiple daily pre-meal injections of glulisine might show superior efficacy in controlling blood glucose, preventing vascular damage and improving treatment satisfaction in diabetic patients.

Hypoglycaemia caused by glucose-lowering therapy has been linked to cardiovascular (CV) events. The ORIGIN trial provides an opportunity to further assess this relationship.. A total of 12 537 participants with dysglycaemia and high CV-risk were randomized to basal insulin glargine titrated to a fasting glucose of ≤ 5.3 mmol/L (95 mg/dL) or standard glycaemic care. Non-severe hypoglycaemia was defined as symptoms confirmed by glucose ≤ 54 mg/dL and severe hypoglycaemia as a requirement for assistance or glucose ≤ 36 mg/dL. Outcomes were: (i) the composite of CV death, non-fatal myocardial infarction or stroke; (ii) mortality; (iii) CV mortality; and (iv) arrhythmic death. Hazards were estimated before and after adjustment for a hypoglycaemia propensity score. During a median of 6.2 years (IQR: 5.8-6.7), non-severe hypoglycaemic episodes occurred in 41.7 and 14.4% glargine and standard group participants, respectively, while severe episodes occurred in 5.7 and 1.8%, respectively. Non-severe hypoglycaemia was not associated with any outcome following adjustment. Conversely, severe hypoglycaemia was associated with a greater risk for the primary outcome (HR: 1.58; 95% CI: 1.24-2.02, P < 0.001), mortality (HR: 1.74; 95% CI: 1.39-2.19, P < 0.001), CV death (HR: 1.71; 95% CI: 1.27-2.30, P < 0.001) and arrhythmic death (HR: 1.77; 95% CI: 1.17-2.67, P = 0.007). Similar findings were noted for severe nocturnal hypoglycaemia for the primary outcome and mortality. The severe hypoglycaemia hazard for all four outcomes was higher with standard care than with insulin glargine.. Severe hypoglycaemia is associated with an increased risk for CV outcomes in people at high CV risk and dysglycaemia. Although allocation to insulin glargine vs. standard care was associated with an increased risk of severe and non-severe hypoglycaemia, the relative risk of CV outcomes with hypoglycaemia was lower with insulin glargine-based glucose-lowering therapy than with the standard glycaemic control.

Microcirculatory and endothelial dysfunction are signs of cardiovascular engagement in patients with type 2 diabetes. This study tested whether glucose normalisation may reverse this.. Thirty-nine T2DM patients (age 61±7 years, 58% females) with signs of mild diastolic dysfunction were randomised to strict glucose control based on insulin (I-group; n=21) or oral agents (O-group; n=18) for four months. Skin microcirculation was studied with laser Doppler fluxmetry and endothelial function with brachial artery flow-mediated dilatation.. Glucose control improved (reduction of HbA(1c) I-group = -0.5%; O-group -0.7%; p=0.69). Microcirculation improved in the entire group (n=39) determined by foot laser Doppler fluxmetry (32.2±13.6 vs. 35.3±13.1 perfusion units; p<0.001) and laser Doppler fluxmetry following heating (68.8±34.0 vs. 69.3±25.1 PU; p=0.007). Improvement was more consistent with oral agents than insulin. Endothelial function expressed as flow-mediated dilatation decreased in the I-group (6.0±2.2 to 4.7±3.0%; p=0.037) but remained unchanged in the O-group (4.8±2.3 to 5.0±3.7%; n.s.).. Glycaemic normalisation improved skin microcirculation but not endothelial function in patients with type 2 diabetes with mild cardiovascular engagement.

Chronic diabetic complications result from an imbalance between vascular damage and regeneration. Several circulating lineage-committed progenitor cells have been implicated, but no data are available on pericyte progenitor cells (PPCs). Based on the evidence that PPCs increase in cancer patients after chemotherapy, we explored whether circulating PPC levels are affected by glucose control in type 2 diabetic patients, in relation to the presence of chronic complications. We enumerated peripheral blood PPCs as Syto16+CD45-CD31-CD140b+ events by flow cytometry at baseline and after 3 and 6 months of glucose control by means of add-on basal insulin therapy on top of oral agents in 38 poorly controlled type 2 diabetic patients. We found that, in patients with microangiopathy (n = 23), the level of circulating PPCs increased about 2 fold after 3 months and then returned to baseline at 6 months. In patients without microangiopathy (control group, n = 15), PPCs remained fairly stable during the whole study period. No relationship was found between change in PPCs and macroangiopathy (either peripheral, coronary, or cerebrovascular). We conclude that glucose control transiently mobilizes PPCs diabetic patients with microangiopathy. Increase in PPCs may represent a vasoregenerative event or may be a consequence of ameliorated glucose control on microvascular lesions.

To test potential differences between the actions of anti-diabetic medications, we examined the effects of oral hypoglycaemic agents versus glargine-apidra insulin therapy in T2DM.. T2DM subjects were randomized to either oral hypoglycaemic agents (pioglitazone, metformin and glipizide, n = 9) or insulin therapy (n = 12) for 6 months. Carotid intimal media thickness, vascular reactivity (flow-mediated vasodilatation; percent change in brachial artery basal diameter post-ischaemia) and sublingual nitrate were measured with ultrasonography. Euglycemic hyperinsulinemic (80 mU/m(2) ) clamp with [3]-3H-glucose and muscle biopsies were performed.. Fasting plasma glucose (~257 to ~124 mg/dL, oral hypoglycaemic agents and ~256 to ~142 mg/dL, IT) and HbA(1c) (~10.3 to ~6.4%, OHA and ~10.7 to ~7.1%, IT) improved comparably. Endogenous glucose production (~2.1 to ~1.7 mg/kg/min, oral hypoglycaemic agents and ~2.3 to ~2.0 mg/kg/min, insulin therapy) and endogenous glucose production suppression by insulin (~0.4 to ~0.3 mg/kg min, oral hypoglycaemic agents and ~0.5 to ~0.7 mg/kg min, insulin therapy) were different. Total glucose disposal × 100 increased in the oral hypoglycaemic agents group (~5.2 to ~8.1; p = 0.03), but not in insulin therapy (~6.0 to ~5.4 mg/kg/min/µU/mL × 100). OHA reduced CIMT (~0.080 to ~0.068 cm; p < 0.05), whereas insulin therapy did not (~0.075 to ~0.072 cm). After sublingual nitrate, brachial artery basal diameter increased in the OHA group (~8.7 to ~18.2%), but not in insulin therapy (~11.2 to ~15.0%; p < 0.02). Except for plasma adiponectin (~7 to ~15, oral hypoglycaemic agents versus ~6 to ~10, IT), changes in inflammatory markers in the circulation and in muscle (IκBα, super-oxidase dismutase 2, monocyte-chemo-attractant protein 1, p-ERK and JNK) were equivalent.. Oral hypoglycaemic agents and insulin therapy treated patients achieved adequate glycemic control and the effects on circulating and muscle inflammatory biomarkers were similar, but only oral hypoglycaemic agents improved insulin sensitivity, vascular function and carotid intimal media thickness. These findings in a small sample suggest that the use of oral hypoglycaemic agents provides additional benefits to patients with T2DM.

In diabetes, endothelial damage promotes macroangiopathy and endothelial regeneration is impaired, owing to reduced endothelial progenitor cells (EPCs). Given that insulin influences endothelial biology, we compared the effects of add-on basal insulin analogues on endothelial damage and regeneration in type 2 diabetes (T2D).. This was a 6-month randomized crossover trial comparing add-on insulin detemir versus glargine in poorly controlled T2D with macroangiopathy. At baseline, crossover (3 months) and study end (6 months), we measured HbA1c, EPCs, circulating endothelial cells (CECs), VCAM-1, ICAM-1 and E-selectin. Body weight and hypoglycaemic episodes were also recorded.. Forty-two patients completed the study, randomly assigned to the glargine-detemir (n = 21) or the detemir-glargine (n = 21) schedule. At crossover, EPC levels did not change compared with baseline, but significantly increased at study end. CECs decreased over time and were significantly reduced at study end. ICAM-1, VCAM-1 and E-selectin were significantly reduced at crossover and further decreased at study end. No differences were seen in these effects between detemir and glargine. HbA1c showed a carryover effect and its reduction was similar with detemir and glargine in the first arm. Incidence of hypoglycaemia and weight gain was lower with detemir than with glargine in both arms.. Optimized glycaemic control by add-on basal insulin improved indexes of endothelial damage and regeneration. Compared to glargine, detemir achieved similar endothelial protection with lower weight gain and less hypoglycaemia. These results might have implications for therapy of aging T2D patients with cardiovascular disease.

To evaluate the long-term clinical and economic outcomes of biphasic insulin aspart 70/30 (BIAsp 70/30) treatment vs. insulin glargine in insulin naïve, type 2 diabetes patients failing oral antidiabetic drugs in a Swedish setting.. A published and validated computer simulation model (the CORE Diabetes Model) was used to project life expectancy, quality-adjusted life expectancy (QALE) and costs over patient lifetimes. Cohort characteristics [54.5% male, mean age 52.4 years, 9 years mean diabetes duration, mean glycosylated haemoglobin (HbA1c) 9.77%] and treatment effects were based on results from the Initiate Insulin by Aggressive Titration and Education (INITIATE) clinical trial. Direct medical costs were accounted in 2006 Swedish Kronor (SEK) and economic and clinical benefits were discounted at 3% per annum.. Biphasic insulin aspart 70/30 treatment when compared with insulin glargine treatment was associated with improvements in discounted life expectancy of 0.21 years (13.10 vs. 12.89 years) and QALE of 0.21 quality-adjusted life years (QALYs) (9.16 vs. 8.96 QALYs). Reductions in the incidence of diabetes-related complications in the BIAsp 70/30 treatment arm led to reduced total costs of SEK 10,367 when compared with insulin glargine (SEK 396,475 vs. SEK 406,842) over patient lifetimes. BIAsp 70/30 treatment was projected to be dominant (cost and lifesaving) when compared with insulin glargine in the base case analysis.. Biphasic insulin aspart 70/30 treatment was associated with improved clinical outcomes and reduced costs compared with insulin glargine treatment over patient lifetimes. These results were driven by improved HbA1c levels associated with BIAsp 70/30 compared with insulin glargine and the accompanying reduction in diabetes-related complications despite increases in body mass index.

To establish the equivalence in efficacy (HbA(1c)) of insulin glargine injected at dinner versus bedtime in a large number of patients with type 1 diabetes using a fast-acting analogue (FAA) or regular human insulin (RHI) as prandial insulin in an insulin glargine-bolus regimen.. In a 26-week trial, 1178 patients with type 1 diabetes and treated with different basal-bolus regimens were randomized to receive insulin glargine once daily at dinner (n=589) or at bedtime (n=589) while continuing their previous prandial insulin (FAA: 75%; RHI: 25% of patients). The primary objective was to demonstrate equivalence in terms of HbA(1c) levels at endpoint.. Baseline characteristics were similar in the two groups. At endpoint, HbA(1c) (mean+/-standard deviation [S.D.]) had decreased by 0.25+/-0.66% to 7.77+/-0.96% in the dinnertime group (P<0.0001), and by 0.24+/-0.76% to 7.83+/-1.07% in the bedtime group (P<0.0001). The HbA(1c) difference between dinner and bedtime was -0.022% (two-sided 90% confidence interval [CI] -0.09; 0.05), demonstrating statistical equivalence of HbA(1c) at endpoint between the two groups. Equivalence was also demonstrated within prandial groups: HbA(1c) difference between dinner and bedtime was -0.03% (two-sided 90% CI: -0.11; 0.06) for FAAs and -0.04% (two-sided 90% CI: -0.19; 0.11) for RHIs. The incidence of severe hypoglycaemia did not differ between the treatment groups.. These data confirm that insulin glargine in combination with either FAA or RHI is equally effective and safe, whether it is administered at dinner or bedtime.

To estimate the long-term cost-effectiveness of exenatide twice daily vs insulin glargine once daily as add-on therapy to oral antidiabetic agents (OADs) for Chinese patients with type 2 diabetes (T2DM).. The Cardiff Diabetes Model was used to simulate disease progression and estimate the long-term effects of exenatide twice daily vs insulin glargine once daily. Patient profiles and treatment effects required for the model were obtained from literature reviews (English and Chinese databases) and from a meta-analysis of 8 randomized controlled trials comparing exenatide twice daily with insulin glargine once daily add-on to OADs for T2DM in China. Medical expenditure data were collected from 639 patients with T2DM (aged ≥18 years) with and without complications incurred between January 1, 2014 and December 31, 2015 from claims databases in Shandong, China. Costs (2014 Chinese Yuan [¥]) and benefits were estimated, from the payers' perspective, over 40 years at a discount rate of 3%. A series of sensitivity analyses were performed.. Patients on exenatide twice daily + OAD had a lower predicted incidence of most cardiovascular and hypoglycaemic events and lower total costs compared with those on insulin glargine once daily + OAD. A greater number of quality-adjusted life years (QALYs; 1.94) at a cost saving of ¥117 706 gained was associated with exenatide twice daily vs insulin glargine once daily. (i.e. cost saving of ¥60 764/QALY) per patient.. In Chinese patients with T2DM inadequately controlled by OADs, exenatide twice daily is a cost-effective add-on therapy alternative to insulin glargine once daily, and may address the problem of an excess of medical needs resulting from weight gain and hypoglycaemia in T2DM treatment.

In the light of a report suggesting that insulin glargine may increase cancer occurrence, the EASD asked us to perform this study.. We followed 114,841 individuals who had a prescription dispensed for insulin between 1 July and 31 December 2005. From 1 January 2006 to 31 December 2007, we noted the occurrence of malignancies. Seven different nationwide registers were used to obtain information on insulin exposure, outcome and possible confounders; these were linked using the unique personal identity number assigned to every Swedish resident.. After adjustment for age and, when appropriate, sex, users of insulin glargine alone (no other types of insulin), compared with users of types of insulin other than insulin glargine, had an RR of 1.99 (95% CI 1.31-3.03) for breast cancer, 0.93 (95% CI 0.61-1.40) for gastrointestinal cancer, 1.27 (95% CI 0.89-1.82) for prostate cancer and 1.07 (95% CI 0.91-1.27) for any type of malignancy. Adjustment for age, smoking, BMI, age at onset of diabetes, age at birth of first child, cardiovascular disease and oestrogen use gave an RR for breast cancer of 1.97 (95% CI 1.29-3.00). The 95% CIs crossed 1.0 for the RR calculated in all analyses of users of insulin glargine in combination with other types of insulin.. In Sweden, during 2006 and 2007, women using insulin glargine alone (no other types of insulin) had an increased incidence rate of breast cancer as compared with women using types of insulin other than insulin glargine. This result may be due to a random fluctuation; the possibilities for examining validity are limited, and no statistically significant results were obtained for any other individual cancer site or for the outcome 'all malignancies'. No definitive conclusions regarding a possible causal relationship between insulin glargine use and the occurrence of malignancies can be drawn from the results of this study.
