Modern antihyperglycemic agents prescribed in Russia for type 2 diabetes mellitus

Aims. To conduct an analysis of modern antihyperglycemic prescription patterns in type 2 diabetes mellitus (T2DM). Materials and methods. Russian DM State registry was studied. Results. We obtained absolute and comparative data on use of insulin analogues, dipeptidyl peptidase-4 (DPP-4) inhibitors and glucagon-like peptide-1 agonists in treatment of T2DM. Conclusion. Percentage of DPP-4 inhibitors and GLP-1 analogues in T2DM treatment patterns remains nominal and does not exceed0.2%, which is significantly lower than in the majority of other countries. Insulin analogues are prescribed considerably more frequentlyand currently appear to be the most promising agents for treatment of T2DM.

Diversity in diabetes: the role of insulin aspart

Diabetes management is changing not only with novel treatments but also in patient demography. This presents clinical challenges and influences our view of diabetes therapies. Insulin analogues have been developed to overcome some of the limitations of traditional human insulins, with the aim of providing a more physiological pharmacokinetic/pharmacodynamic profile. The rapid-acting insulin analogue insulin aspart has been investigated in many clinical trials over the past 10 years and the aim of this review is to present the insulin aspart clinical trial data from across the spectrum of patients with diabetes. Five studies have looked at insulin aspart use (including continuous subcutaneous insulin infusion) in children and adolescents, where the analogue was as effective and well tolerated as soluble human insulin. One large-scale, randomized, controlled trial in pregnant women with type 1 diabetes observed trends towards a reduction in major hypoglycaemia, fewer preterm deliveries and lower birthweight with insulin aspart compared with soluble human insulin. Two 6-month, randomized, controlled, multicentre, multinational, parallel-group, open-label trials reported significant reductions in haemoglobin A(1c) and major nocturnal hypoglycaemia with insulin aspart compared with soluble human insulins in patients with type 1 diabetes. There are fewer data involving insulin analogue use in hospitals and in elderly patients with diabetes, but some recent studies have investigated insulin aspart in the emergency department, intensive/non-intensive care setting and in a pharmacokinetic/pharmacodynamic study in patients aged ≥ 65 years. In summary, the evidence would suggest that insulin aspart is suitable for use in a variety of patients with diabetes.

Continuous glucose monitoring in children, adolescents, and adults with type 1 diabetes mellitus: analysis from the prospective DPV diabetes documentation and quality management system from Germany and Austria

To determine frequency, duration, and relationship of continuous glucose monitoring (CGM) to glycemic control and rate of hypoglycemia in children and adults in Germany and Austria. From 59,920 patients documented in the DPV (Diabetessoftware zur prospektiven Verlaufsdokumentation) database, 144,385 sensor days of 2874 patients using CGM between January 2008 and September 2010 were analyzed. Overall, 4.8% of patients used CGM. In pediatric patients, study period (p = 0.0309), age (p = 0.0140), insulin dose (p < 0.0001), and use of insulin analogs (p < 0.0001) significantly influenced hemoglobin A1c (HbA1c), but duration of diabetes, sex, and CGM use did not. In contrast, adults with longer CGM use (>30 d) had significantly lower HbA1c (p < 0.0016). Severe hypoglycemia was not reduced in patients using CGM for <30 d. CGM is still rarely used in Germany and Austria. CGM use is associated with a significant reduction of HbA1c in adults but not in children. Hypoglycemic events were not reduced, irrespective of age.

Basal insulin analogues in diabetic pregnancy: a literature review and baseline results of a randomised, controlled trial in type 1 diabetes

As basal insulin analogues are being used off-label, there is a need to evaluate their safety (maternal hypoglycaemia and fetal and perinatal outcomes) and efficacy [haemoglobin A1c(HbA1c), fasting plasma glucose, and maternal weight gain]. The aim of this review is to provide an overview of the current literature concerning basal insulin analogue use in diabetic pregnancy, and to present the design and preliminary, non-validated baseline characteristics of a currently ongoing randomized, controlled, open-label, multicentre, multinational trial comparing insulin detemir with neutral protamine hagedorn insulin, both with insulin aspart, in women with type 1 diabetes planning a pregnancy (n = 306) or are already pregnant (n = 164). Inclusion criteria include type 1 diabetes > 12 months' duration; screening HbA1c ≤ 9.0% (women recruited prepregnancy), or pregnant with gestational age 8-12 weeks and HbA1c ≤ 8.0% at randomization. At confirmation of pregnancy all subjects must have HbA1c ≤ 8.0%. Exclusion criteria include impaired hepatic function, cardiac problems, and uncontrolled hypertension. Subjects are randomized to either insulin detemir or neutral protamine hagedorn insulin, both with prandial insulin aspart. The results are expected mid-2011 with full publications expected later this year. Baseline characteristics show that basal insulin analogues are already frequently used in pregnant women with type 1 diabetes. This study will hopefully elucidate the safety and efficacy of the basal insulin analogue detemir in diabetic pregnancy.

Diferencias de estado nutricional, control metabólico y tratamiento de la diabetes tipo 1 en dos décadas

Objective The aim of this study is to describe changes in anthropometric characteristics, metabolic control, treatment and prevalence of overweight in diabetic children (DM1) from 2007 compared with another similar group from 1986. Patients and methods Observational retrospective study of two groups of diabetic children (n = 90). The collection of variables has been made at two cross-sections, 1986 and 2007. The studied variables were: age, years of DM1, sex, weight, height, BMI (and their Z values), HbA 1c and treatment with insulin (type, number of doses, IU/day and IU/kg/day). Results In 2007 group there is a significant increase in Z-weight and Z-BMI ( P = .001) when compared with the 1986 group. There was a negative relationship between the years with DM1 and Z-height ( P = .05) in the 1986 group. The value of HbA 1c was lower in the 2007 group ( P = .001), but the dose of insulin (IU/day and IU/kg/day) was similar in both groups. The number of daily doses of insulin was higher in the 2007 group ( P < .001), the use of insulin analogues dominated overall. A statistically significant relationship between HbA 1c and treatment with insulin (dose injections, insulin type) was not found. The prevalence of overweight (14.6% vs 2.4%) was significantly higher in the 2007 Group ( P = .001). Conclusions The metabolic control (HbA 1c) had improved and the use of multiple daily doses of insulin has been become the standard, but the prevalence of overweight has increased. We must monitor the emergence of insulin resistance and cardiovascular risk factors in this sensitive population to prevent early cardiovascular disease.

Therapeutic management of type 1 diabetes before and during pregnancy

Introduction: Pregnancy increases the risks of adverse outcomes for mother and infant in women with type 1 diabetes. Obtaining and maintaining adequate glycemic control during pregnancy is crucial for optimizing outcomes.Areas covered: The importance of prepregnancy planning and treatment during pregnancy is reviewed. The use of insulin analogues and antihypertensive drugs in diabetic pregnancy are in focus. The reader is presented with evidence discussing the importance of prepregnancy counseling and treatment during pregnancy in women with type 1 diabetes.Expert opinion: Tight glycemic control before and during pregnancy is crucial and the prevalence of severe hypoglycemia during pregnancy needs to be reduced. Rapid-acting insulin analogues are regarded as safe to use in pregnancy and studies on long-acting insulin analogues are in the pipeline. Supplementation with folic acid may reduce the risk of malformations. Screening for diabetic retinopathy, diabetic nephropathy and thyroid dysfunction is important, and indications for antihypertensive treatment and treatment of thyroid dysfunction need to be in focus before and during pregnancy.

Closing the loop

Closed-loop algorithms can be found in every aspect of everyday modern life. Automation and control are used constantly to provide safety and to improve quality of life. Closed-loop systems and algorithms can be found in home appliances, automobiles, aviation and more. Can one imagine nowadays driving a car without ABS, cruise control or even anti-sliding control? Similar principles of automation and control can be used in the management of diabetes mellitus (DM). The idea of an algorithmic/technological way to control glycaemia is not new and has been researched for more than four decades. However, recent improvements in both glucose-sensing technology and insulin delivery together with advanced control and systems engineering made this dream of an artificial pancreas possible. The artificial pancreas may be the next big step in the treatment of DM since the use of insulin analogues. An artificial pancreas can be described as internal or external devices that use continuous glucose measurements to automatically manage exogenous insulin delivery with or without other hormones in an attempt to restore glucose regulation in individuals with DM using a control algorithm. This device as described can be internal or external; can use different types of control algorithms with bi-hormonal or uni-hormonal design; and can utilise different ways to administer them. The different designs and implementations have transitioned recently from in silico simulations to clinical evaluation stage with practical applications in mind. This may mark the beginning of a new era in diabetes management with the introduction of semi-closed-loop systems that can prevent or minimise nocturnal hypoglycaemia, to hybrid systems that will manage blood glucose (BG) levels with minimal user intervention to finally fully automated systems that will take the user out of the loop. More and more clinical trials will be needed for the artificial pancreas to become a reality but initial encouraging results are proof that we are on the right track. We attempted to select recent publications that will present these current achievements in the quest for the artificial pancreas and that will inspire others to continue to progress this field of research.

Increasing Trend in the Number of Severe Hypoglycemia Patients in Korea

BackgroundTo investigate whether the number of subjects with severe hypoglycemia who are brought to a hospital emergency department is increasing and to identify whether there have been changes in the demographic and clinical characteristics of those subjects.MethodsWe analyzed data from the Emergency Departments of two general hospitals in Seoul, Korea. We included data from all adult subjects with type 2 diabetes who presented to an emergency department with severe hypoglycemia between January 1, 2004 and December 30, 2009.ResultsA total of 740 cases of severe hypoglycemia were identified. The mean subject age was 69±12 years, mean duration of diabetes was 13.8±9.3 years, and 53.2% of subjects were receiving insulin therapy. We observed a sharp rise in the number of cases between 2006 and 2007. Stages 3-5 chronic kidney disease was diagnosed in 31.5% of subjects, and low C-peptide levels (<0.6 ng/mL) were found in 25.5%. The mean subject age, duration of diabetes, HbA1c level, and renal and insulin secretory function values did not change significantly during the study period. The proportion of glimepiride use increased, while use of gliclazide decreased among sulfonylurea users. Use of insulin analogues increased, while use of NPH/RI decreased among insulin users.ConclusionWe identified a sharp increase in the number of subjects with severe hypoglycemia presenting to an emergency room since 2006. The clinical characteristics of these subjects did not change markedly during the study period. Nationwide studies are warranted to further clarify this epidemic of severe hypoglycemia.

The aim of this study was to determine changes in weight and insulin requirements in insulin-treated type 2 diabetic patients with normal and elevated body mass index (BMI) during the first year after initiating the insulin therapy with insulin analogues or human insulins, respectively. Materials and methods: a total of 157 patients with insulin naive type 2 diabetes were included in the study. The patients were divided in two groups. First group consisted of subjects [mean age 57 (45 to 73), duration of diabetes of 10 years (4 to 16)] prescribed a long-acting basal (glargine, detemir), premixed (biphasic insulin Aspart 30, Humalog Mix 25) or short-acting (aspart, lispro) insulin analogues. Patients from second group [mean age 59 (46 to 75), duration of diabetes for 10 years (5 to 15)] were treated with intermediate- acting basal (Protophane, Humulin NPH), premixed (biphasic human insulin 30, Humulin M3) and regular (Actrapid, Humulin R) human insulins. Each of these two groups was divided into three subgroups depending on the baseline body mass index (BMI) of the patients: 18,5-24,9; 25-29 and ≥30. At the beginning of insulin therapy and 12 months later, we compared HbA1c, BMI, waist circumference and required insulin doses in each group. Results: our study results showed that under comparable metabolic control the risk for weight gain and increase in insulin requirement is similar in insulin-treated type 2 diabetic patients with normal and elevated BMI. Use of insulin analogues for treatment of type 2 diabetes patients with normal and elevated BMI results in better glycaemic control, less weight gain, smaller increase in insulin requirement and waist circumference compared to human insulins during the first year of insulin therapy.

The role of insulin analogs in the achievement of compensation and improvement of quality of life in children and adolescents with type 1 diabetes mellitus

Despite substantial progress in the treatment of type 1 diabetes mellitus achieved by the end of the last century due to the advent of human insulins,intensive insulinotherapy, means of glycemia self-control, and active patient self-management education, compensation of the diseases in childrenand adolescents remains a challenging problem. This paper is focused on the use of insulin analogs in these patients and main difficulties encounteredby pediatricians in the correction of therapy.

Insulinothérapie : insuline ou analogues ? Injection ou perfusion ? Boucle ouverte ou boucle fermée ?

Insulin has been purified, humanized and then synthesized by microorganisms. It is mandatory to be able to use insulin, whose kinetics and reproducibility allow glycemia near to normal without increasing hypoglycemia. Use of insulin analogs allows a slight improvement in glycemic control and decrease hypoglycemia frequency. Flexibility of treatment is also improved. “Continuous subcutaneous insulin infusion” (CSII) using rapid analogs mimics physiologic insulin secretion. Major indications are: high HbA1c despite well-managed basal-bolus regimen, severe hypoglycemia, brittle diabetes or “dawn phenomenon”. Children, adolescents as well as pregnancy are also good indications. “Continuous intraperitoneal insulin infusion” major interest is the predominant absorption via the portal system. Kinetic is comparable to rapid analogs delivered subcutaneously. The dramatic reduction of severe hypoglycemic events has been related to good reproducibility of insulin absorption and restoration of glucagon response. Hypoglycemia prone type 1 diabetic patients, uncontrolled with well-managed CSII as well as subcutaneous insulin resistance are the major indications. The association of optimized insulin therapy to “real time continuous glucose monitoring” allows better doses adaptation. Alarms can be set to avoid glycemic excursions and thus severe hypoglycemia. Using these devices, HbA1c is significantly improved without any increase in hypoglycemic events. These devices are one of the steps towards the “closed-loop insulin delivery” concept. Restoration of missing beta-cell function by an automated, glucose-modulated, insulin-delivery system would allow near normal glycemia without the risk of hypoglycemia. First studies show a good regulation of interprandial glycemia; prandial doses seem more difficult to assess. Nevertheless the “holy grail” might be closer than we think.

Seguridad de los análogos de insulina: qué evaluar, cómo hacerlo y cómo interpretar los resultados

The widespread use of insulin analogues is based not only on the pharmacokinetics of these preparations, which is much closer to the physiology of insulin secretion under normal conditions, but also on their safety and effectiveness. The publication of a possible association between the use of a long-acting insulin analogue (glargine) and breast cancer has caused uneasiness among the medical community regarding the safety of these analogues. The mechanism of increased tumor activity of insulin analogues is explained by the fact that they act through insulin receptors (IR) and insulin-like growth factor-1 (IGF-1R), stimulating cell growth and inhibiting apoptosis. There are two major mechanisms: an increase in the binding time of insulin to IR and increased activation of IGF-1R. Therefore, to evaluate the safety of an analogue, the slower dissociation rate from its insulin receptor must be excluded, as well as the increased affinity for the IGF-1 receptor. This is equivalent to an index of mitogenic/metabolic activity of less than 1. These aspects can only be evaluated through study of cell lines and animal testing, which are reductionist models that cannot always be extrapolated to humans. To date, there are no data to question the safety of insulin analogues in general. However, the results of observational studies and some in vitro studies, suggesting a potential risk of mitogenicity with the administration of glargine, have caused some alarm among the medical community. Until now, there are no data to refute or confirm this risk and, therefore, evaluation of the existing data is crucial to obtain objective information.

EFFICIENCY OF INSULINOTHERAPY OF DIABETES MELLITUS TYPE 1 IN CHILDREN AND ADOLESCENTS

Analysis of the treatment of type-1 diabetes in children and adolescents in recent years has shown a significant increase in using of insulin analogues. Improvement in the compensation of carbohydrate metabolism and state of microcirculation on the background of the use of insulin analogues when compared with other insulin drugs is shown. The importance of maintaining stable blood glucose levels at night to prevent the development of microcirculatory disorders, which is ensured, primarily by the drugs of non-peak prolonged insulin action was proved.

Critical appraisal of the safety and efficacy of insulin detemir in glycemic control and cardiovascular risk management in diabetics

Critical appraisal of the safety and efficacy of insulin detemir in glycemic control and cardiovascular risk management in diabetics Jean-Pierre Le FlochDepartment of Diabetology, Medical Clinic, Villecresnes, FranceAbstract: Insulin detemir is an analog of human insulin designed to provide a long duration of basal insulin action. This is achieved by protracted absorption from the injection depot, which results in part from increased self-association of insulin detemir molecules and in part from reversible albumin binding. Subsequent albumin binding in the circulation is thought to buffer changes in the effects at target tissues that could otherwise arise from variability in absorption rate. In consequence, insulin detemir has shown a less variable pharmacodynamic profile than alternative basal insulins; this manifests as more consistent temporal glucose reduction profiles in repeat-clamp studies. In clinical trials, insulin detemir has been characterized by consistent risk reductions in hypoglycemia, as well as reduced weight gain in comparison with other basal insulins. Given some recent associations that have been made in prospective and epidemiologic studies between glucose variability and/or hypoglycemia and increased cardiovascular risk, and the long-known association between excess weight and cardiovascular risk, it is possible that the clinical profile of insulin detemir may carry prognostic value with regard to cardiovascular safety, although this is yet to be substantiated. There have also been some concerns raised recently over the use of insulin analogs and cancer risk, but available clinical data and the receptor interaction profile of insulin detemir suggest no excess in risk in comparison with human insulin therapy. Optimal approaches for the clinical use of insulin detemir have been emerging through an increasing clinical study base, and the analog is becoming established as a potentially valuable therapy option.Keywords: insulin detemir, type 2 diabetes, glucose variability, hypoglycemia, weight gain

Lipoatrophy associated with the use of insulin analogues: a new case associated with the use of insulin glargine and review of the literature

Importance of the field: Any insulin formulation can in principle cause lipoatrophy; even cases associated with recombinant human insulin have been reported. An increasing number of case reports have been published indicating that lipoatrophy also develops after treatment with various insulin analogues.Areas covered in this review: In this review, we summarise the literature on lipoatrophy associated with the use of insulin analogues published to date. A new case of lipoatrophy associated with the use of glargine is presented.What the reader will gain: Readers will gain insight into: i) pathogenesis of lipoatrophy associated with the use of insulin analogues and ii) clinical features of lipoatrophy.Take home message: Twelve cases with lipoatrophy under treatment with insulin analogues have been reported so far. The exclusive occurrence in lean type 1 diabetic patients, its overlap with further autoimmune diseases and the overrepresentation of female individuals point to an immune pathogenesis. The respective exposition to the analogues lispro, aspart, glargine and detemir prior to lipoatrophy development varied considerably between 4 weeks and 2 years. No spontaneous substantial recovery of lipoatrophic areas has been reported. Frequent use of the same pen needle and lack of rotating of insulin injection sites seem to favour the development of lipoatrophy.

The influence of glucose-lowering therapies on cancer risk in type 2 diabetes

The risk of developing a range of solid tumours is increased in type 2 diabetes, and may be influenced by glucose-lowering therapies. We examined the risk of development of solid tumours in relation to treatment with oral agents, human insulin and insulin analogues. This was a retrospective cohort study of people treated in UK general practices. Those included in the analysis developed diabetes >40 years of age, and started treatment with oral agents or insulin after 2000. A total of 62,809 patients were divided into four groups according to whether they received monotherapy with metformin or sulfonylurea, combined therapy (metformin plus sulfonylurea), or insulin. Insulin users were grouped according to treatment with insulin glargine, long-acting human insulin, biphasic analogue and human biphasic insulin. The outcome measures were progression to any solid tumour, or cancer of the breast, colon, pancreas or prostate. Confounding factors were accounted for using Cox proportional hazards models. Metformin monotherapy carried the lowest risk of cancer. In comparison, the adjusted HR was 1.08 (95% CI 0.96-1.21) for metformin plus sulfonylurea, 1.36 (95% CI 1.19-1.54) for sulfonylurea monotherapy, and 1.42 (95% CI 1.27-1.60) for insulin-based regimens. Adding metformin to insulin reduced progression to cancer (HR 0.54, 95% CI 0.43-0.66). The risk for those on basal human insulin alone vs insulin glargine alone was 1.24 (95% CI 0.90-1.70). Compared with metformin, insulin therapy increased the risk of colorectal (HR 1.69, 95% CI 1.23-2.33) or pancreatic cancer (HR 4.63, 95% CI 2.64-8.10), but did not influence the risk of breast or prostate cancer. Sulfonylureas were associated with a similar pattern of risk as insulin. Those on insulin or insulin secretagogues were more likely to develop solid cancers than those on metformin, and combination with metformin abolished most of this excess risk. Metformin use was associated with lower risk of cancer of the colon or pancreas, but did not affect the risk of breast or prostate cancer. Use of insulin analogues was not associated with increased cancer risk as compared with human insulin.

Cost-effectiveness of insulin analogues for diabetes mellitus

Insulin analogues may be associated with fewer episodes of hypoglycemia than conventional insulins. However, they are costly alternatives. We compared the cost-effectiveness of insulin analogues and conventional insulins used to treat type 1 and type 2 diabetes mellitus in adults. We conducted a cost-effectiveness evaluation of insulin analogues versus conventional insulins using the Center for Outcomes Research Diabetes Model. We compared rapid-acting analogues (insulin aspart and insulin lispro) with regular human insulin, and long-acting analogues (insulin glargine and insulin detemir) with neutral protamine Hagedorn insulin. We derived clinical information for the comparisons from meta-analyses of randomized controlled trials. We obtained cost and utility estimates from published sources. We performed sensitivity analyses to test the robustness of our results. For type 1 diabetes, insulin aspart was more effective and less costly than regular human insulin. Insulin lispro was associated with an incremental cost of Can$28,996 per quality-adjusted life-year. The incremental cost per quality-adjusted life-year was Can$87,932 for insulin glargine and Can$387,729 for insulin detemir, compared with neutral protamine Hagedorn insulin. For type 2 diabetes, insulin aspart was associated with an incremental cost of Can$22,488 per quality-adjusted life-year compared with regular human insulin. For insulin lispro, the incremental cost was Can$130,865. Compared with neutral protamine Hagedorn insulin, insulin detemir was less effective and more costly. Insulin glargine was associated with an incremental cost of Can$642,994 per quality-adjusted life-year. The model was sensitive to changes in the effect size of hemoglobin A(1c) and to decrements applied to utility scores when fear of hypoglycemia was included as a factor. The cost-effectiveness of insulin analogues depends on the type of insulin analogue and whether the patient receiving the treatment has type 1 or type 2 diabetes. With the exception of rapid-acting insulin analogues in type 1 diabetes, routine use of insulin analogues, especially long-acting analogues in type 2 diabetes, is unlikely to represent an efficient use of finite health care resources.
