Prospective randomised study of intensive insulin treatment on long term survival after acute myocardial infarction in patients with diabetes mellitus. DIGAMI (Diabetes Mellitus,Insulin Glucose Infusion in Acute Myocardial Infarction) Study Group.

OBJECTIVES: To test the hypothesis that intensive metabolic treatment with insulin-glucose infusion followed by multidose insulin treatment in patients with diabetes mellitus and acute myocardial infarction improves the prognosis. DESIGN: Patients with diabetes mellitus and acute myocardial infarction were randomly allocated standard treatment plus insulin-glucose infusion for at least 24 hours followed by multidose insulin treatment or standard treatment (controls). SUBJECTS: 620 patients were recruited, of whom 306 received intensive insulin treatment and 314 served as controls. MAIN OUTCOME MEASURE: Long term all cause mortality. RESULTS: The mean (range) follow up was 3.4 (1.6-5.6) years. There were 102 (33%) deaths in the treatment group compared with 138 (44%) deaths in the control group (relative risk (95% confidence interval) 0.72 (0.55 to 0.92); P = 0.011). The effect was most pronounced among the predefined group that included 272 patients without previous insulin treatment and at a low cardiovascular risk (0.49 (0.30 to 0.80); P = 0.004). CONCLUSION: Insulin-glucose infusion followed by intensive subcutaneous insulin in diabetic patients with acute myocardial infarction improves long term survival, and the effect seen at one year continues for at least 3.5 years, with an absolute reduction in mortality of 11%. This means that one life was saved for nine treated patients. The effect was most apparent in patients who had not previously received insulin treatment and who were at a low cardiovascular risk.

Real-World Insulin Treatment Persistence among Patients with Type 2 Diabetes

ObjectiveTo evaluate real-world treatment persistence among patients with type 2 diabetes mellitus (T2DM) initiating treatment with insulin.MethodsPatient-level data were pooled from 3 previously published observational retrospective studies evaluating patients with T2DM who were previously on oral antidiabetic drugs (OADs) and initiated with a basal analog insulin (insulin glargine or insulin detemir). Treatment persistence was defined as remaining on the study drug during the 1-year follow-up period without discontinuation or switching after study drug initiation. Analyses were conducted to identify baseline factors associated with persistence with insulin therapy and to estimate the association between insulin treatment persistence and patients’ clinical and economic outcomes during the follow-up period.ResultsA total of 4,804 patients with T2DM (insulin glargine: n = 4,172, insulin detemir: n = 632) were included. The average insulin persistence rate over the 1-year follow-up period was 65.0%. A significantly higher persistence rate was associated with older age, initiation with insulin glargine using either disposable pens or vial-and-syringe, and with baseline exenatide or sitagliptin use. Higher insulin treatment persistence was also associated with lower hemoglobin A_1c (A1C) at follow-up, a greater reduction in A1C from baseline, and lower health care utilization.ConclusionIn real-world settings, treatment persistence among patients with T2DM initiating basal insulin is influenced by the type of insulin and patient factors. Greater insulin treatment persistence is linked to improved clinical outcomes and reduced health care utilization. (Endocr Pract. 2014;20:52-61)     

Clinical parameters (body mass index and age) are the best predictors for the need of insulin therapy during the first 18 months of diabetes mellitus in young adult patients.

To address the question whether there are simple clinical predictors of need for insulin in the first 18 months of treatment of diabetes presenting in young adult subjects, a prospective study of 24 patients with diabetes mellitus (age: 18-40 years) was designed. At diagnosis of diabetes, age, sex, body mass index (BMI), glycemia, ketonuria, C-peptide, insulin autoantibodies, islet cell antibodies and glutamic acid decarboxylase antibodies were recorded before starting any treatment. At the end of the follow-up (18 +/- 4 months), they were divided into two groups according to their need for insulin therapy: group 1 (n=15; 62%), who needed insulin therapy, and group 2 (n=9; 38%), who did not. Each marker was related to actual need for therapy necessity. Multivariate analysis showed that BMI and age were the variables with greatest predictive value regarding need for insulin. These data reveal that the need for insulin therapy in young adult diabetic patients may be supported by the clinical criteria of age and BMI, which are both easily and quickly determined.

Role of incretin hormones in the regulation of insulin secretion in diabetic and nondiabetic humans

The available evidence suggests that about two-thirds of the insulin response to an oral glucose load is due to the potentiating effect of gut-derived incretin hormones. The strongest candidates for the incretin effect are glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide 1 (GLP-1). In patients with type 2 diabetes, however, the incretin effect is lost or greatly impaired. It is hypothesized that this loss explains an important part of the impaired insulin secretion in patients. Further analysis of the incretin effects in patients has revealed that the secretion of GIP is near normal, whereas the secretion of GLP-1 is decreased. On the other hand, the insulintropic effect of GLP-1 is preserved, whereas the effect of GIP is greatly reduced, mainly because of a complete loss of the normal GIP-induced potentiation of second-phase insulin secretion. These two features, therefore, explain the incretin defect of type 2 diabetes. Strong support for the hypothesis that the defect plays an important role in the insulin deficiency of patients is provided by the finding that administration of excess GLP-1 to patients may completely restore the glucose-induced insulin secretion as well as the beta-cells' sensitivity to glucose. Because of this, analogs of GLP-1 or GLP-1 receptor activations are currently being developed for diabetes treatment, so far with very promising results.     

Therapeutic potential of human embryonic stem cells in type 2 diabetes mellitus

AIM:To evaluate the safety and efficacy of human embryonic stem cells(h ESCs)for the management of type 2 diabetes mellitus(T2DM).METHODS:Patients with a previous history of diabetes and its associated complications were enrolled and injected with hE SC lines as per the defined protocol.The patients were assessed using Nutech functional score(NFS),a numeric scoring scale to evaluate the patients for 11 diagnostic parameters.Patients were evaluated at baseline and at the end of treatment period 1(T1).All the parameters were graded on the NFS scale from 1to 5.Highest possible grade(HPG)of 5 was considered as the grade of best improvement.RESULTS:Overall,94.8%of the patients showed improvement by at least one grade of NFS at the end of T1.For all the 11 parameters evaluated,54%of patients achieved HPG after treatment.The four essential parameters(improvement in glycated hemoglobin(HbA 1c)and insulin level,and fall in number of other oral hypoglycemic drugs with and without insulin)are presented in detail.For Hb A1c,72.6%of patients at the end of T1 met the World Health Organization cut off value,i.e.,6.5%of HbA 1c.For insulin level,65.9%of patients at the end of T1 were able to achieve HPG.After treatment,the improvement was seen in 16.3%of patients who required no more than two medications along with insulin.Similarly,21.5%of patients were improved as their dosage regimen for using oral drugs was reduced to 1-2 from 5.CONCLUSION:hE SC therapy is beneficial in patients with diabetes and helps in reducing their dependence on insulin and other medicines.

Oxidative stress as a mechanism of diabetes in diabetic BB prone rats: Effect of secoisolariciresinol diglucoside (SDG)

Secoisolariciresinol diglucoside (SDG) isolated from flaxseed has antioxidant activity and has been shown to prevent hypercholesterolemic atherosclerosis. An investigation was made of the effects of SDG on the development of diabetes in diabetic prone BioBreeding rats (BBdp rats), a model of human type I diabetes [insulin dependent diabetes mellitus (IDDM)] to determine if this type of diabetes is due to oxidative stress and if SDG can prevent the incidence of diabetes. The rats were divided into three groups: Group I, BioBreeding normal rats (BBn rats) (n = 10); group II, BBdp untreated (n = 11); and group III, BBdp treated with SDG 22 mg/kg body wt, orally) (n = 14). Oxidative stress was determined by measuring lipid peroxidation product malondialdehyde (MDA) an index of level of reactive oxygen species in blood and pancreas; and pancreatic chemiluminescence (Pancreatic-CL), a measure of antioxidant reserve. Incidence of diabetes was 72.7% in untreated and 21.4% in SDG-treated group as determined by glycosuria and hyperglycemia. SDG prevented the development of diabetes by approximately 71%. Development of diabetes was associated with an increase in serum and pancreatic MDA and a decrease in antioxidant reserve. Prevention in development of diabetes by SDG was associated with a decrease in serum and pancreatic-MDA and an increase in antioxidant reserve. These results suggest that IDDM is mediated through oxidative stress and that SDG prevents the development of diabetes.     

Multi-minicore Disease

Transient (TNDM) and Permanent (PNDM) Neonatal Diabetes Mellitus are rare conditions occurring in 1:300,000–400,000 live births. TNDM infants develop diabetes in the first few weeks of life but go into remission in a few months, with possible relapse to a permanent diabetes state usually around adolescence or as adults. The pancreatic dysfunction in this condition may be maintained throughout life, with relapse initiated at times of metabolic stress such as puberty or pregnancy. In PNDM, insulin secretory failure occurs in the late fetal or early post-natal period and does not go into remission. Patients with TNDM are more likely to have intrauterine growth retardation and less likely to develop ketoacidosis than patients with PNDM. In TNDM, patients are younger at the diagnosis of diabetes and have lower initial insulin requirements. Considerable overlap occurs between the two groups, so that TNDM cannot be distinguished from PNDM based on clinical features. Very early onset diabetes mellitus seems to be unrelated to autoimmunity in most instances. A number of conditions are associated with PNDM, some of which have been elucidated at the molecular level. Among these, the very recently elucidated mutations in the KCNJ11 and ABCC8 genes, encoding the Kir6.2 and SUR1 subunit of the pancreatic K_ATP channel involved in regulation of insulin secretion, account for one third to half of the PNDM cases. Molecular analysis of chromosome 6 anomalies (found in more than 60% in TNDM), and the KCNJ11 and ABCC8 genes encoding Kir6.2 and SUR1, provides a tool to identify TNDM from PNDM in the neonatal period. This analysis also has potentially important therapeutic consequences leading to transfer some patients, those with mutations in KCNJ11 and ABCC8 genes, from insulin therapy to sulfonylureas. Recurrent diabetes is common in patients with "transient" neonatal diabetes mellitus and, consequently, prolonged follow-up is imperative. Realizing how difficult it is to take care of a child of this age with diabetes mellitus should prompt clinicians to transfer these children to specialized centers. Insulin therapy and high caloric intake are the basis of the treatment. Insulin pump may offer an interesting therapeutic tool in this age group in experienced hands.     

Diabetes Mellitus: Distinguishing Between Patients Receiving Insulin and Those Requiring Insulin Therapy

Fifteen patients with maturity onset type diabetes, all of whom had received insulin for periods of one to thirty-five years, were admitted to hospital and insulin treatment was discontinued. Within 24 to 48 hours each patient was given an intravenous tolbutamide test, following which all were given either diet therapy alone or diet therapy plus oral agents. If significant hyperglycemia or ketonemia resulted, insulin therapy was reinstituted.Approximately 50 percent (8 of 15) of the patients showed improvement in fasting blood sugar levels following discontinuation of insulin. It was not possible to distinguish the insulin independent from the insulin dependent group using such criteria as age, sex, degree of overweight, insulin dosage, duration of diabetes or duration of insulin therapy. However, using the intravenous tolbutamide test it was possible to differentiate between the two groups. Those who did not require insulin responded to intravenous tolbutamide with a glucose decrease greater than 10 percent from the initial value. The insulin dependent group had either no glucose decrease or a rise in blood glucose following intravenous administration of tolbutamide.     

Babies born small for gestational age: insulin sensitivity and growth hormone treatment

Epidemiological studies have identified an association between size at birth and adult risk for type 2 diabetes mellitus and cardiovascular disease. In contemporary populations, children who are relatively small at birth and show rapid infancy weight gain are at greatest risk for the development of childhood obesity, increased visceral fat and insulin resistance: possible early markers of adult disease risk. Individuals presenting to growth clinics with short stature and a history of low birthweight will not have shown post-natal catch-up growth and may be a very heterogeneous group. Nevertheless, there are some data to suggest that as a group they are insulin resistant with decreased lean mass. Growth hormone treatment leads to reversible worsening of the insulin resistance, and short-term data do not indicate an increased risk for type 2 diabetes. However, further long-term follow-up is required, and particular care should be taken in monitoring children with a strong family history of type 2 diabetes and those from ethnic groups in which there is a high background prevalence of the disease.     

Long-Acting Subcutaneously Administered Insulin for Glycemic Control Immediately After Cardiac Surgery

ObjectiveTo test the hypothesis that subcutaneous administration of basal insulin begun immediately after cardiac surgery can decrease the need for insulin infusion in patients without diabetes and save nursing time.MethodsAfter cardiac surgery, 36 adult patients without diabetes were randomly assigned to receive either standard treatment (control group) or insulin glargine once daily in addition to standard treatment (basal insulin group). Standard treatment included blood glucose measurements every 1 to 4 hours and intermittent insulin infusion to maintain blood glucose levels between 100 and 150 mg/dL. The study period lasted up to 72 hours.ResultsThere were no differences in demographics or baseline laboratory characteristics of the 2 study groups. Mean daily blood glucose levels were lower in the basal insulin group in comparison with the control group, but the difference was not statistically significant (129.3 ± 9.4 mg/ dL versus 132.6 ± 7.3 mg/dL; P = .25). The mean duration of insulin infusion was significantly shorter in the basal insulin group than in the control group (16.3 ± 10.7 hours versus 26.6 ± 17.3 hours; P = .04). Nurses tested blood glucose a mean of 8.3 ± 3.5 times per patient per day in the basal insulin group and 12.0 ± 4.7 times per patient per day in the control group (P = .01). There was no occurrence of hypoglycemia (blood glucose level < 60 mg/dL) in either group.ConclusionOnce-daily insulin glargine is safe and may decrease the duration of insulin infusion and reduce nursing time in patients without diabetes who have hyperglycemia after cardiac surgery.

A one-year, randomised, multicentre trial comparing insulin glargine with NPH insulin in combination with oral agents in patients with type 2 diabetes.

AIMS: The aim of the trial was to compare the efficacy and safety of the new, long-acting basal insulin, insulin glargine (LANTUS(R)), with NPH human insulin, each administered in a combination regimen with oral antidiabetic drugs in patients with Type 2 diabetes. METHODS: In a multicentre, open, randomised study, 570 patients with Type 2 diabetes, aged 34 - 80 years, were treated for 52 weeks with insulin glargine or NPH insulin given once daily at bedtime. Previous oral antidiabetic therapy was continued throughout the study. RESULTS: There was a clinically relevant decrease in glycosylated haemoglobin (GHb) values from baseline to endpoint with both drugs (insulin glargine: - 0.46 %; NPH insulin: - 0.38 %; p = 0.415); also, this difference was statistically significant in the subgroup of overweight patients with BMI > 28 kg/m 2 (insulin glargine: - 0.42 %, NPH insulin: - 0.11 %; p = 0.0237). Over the entire treatment period, NPH insulin-treated patients (41 %) and insulin glargine-treated patients (35 %) experienced a similar level of symptomatic hypoglycaemia. A statistically significant difference was observed in the number of patients treated with NPH insulin who reported at least one episode of nocturnal hypoglycaemia compared with those treated with insulin glargine in the overall population and in the overweight subgroup (overall: 24 % vs. 12 %, p = 0.002; overweight: 22.2 % vs. 9.5 %, p = 0.0006), using the Cochran-Mantel-Haenszel test. These differences were most pronounced in insulin-na?ve and overweight (BMI > 28 kg/m 2) sub-groups. The incidence of adverse events was similar for the two treatments. CONCLUSIONS: This study demonstrated that insulin glargine is as effective as NPH insulin in achieving glycaemic control in patients with Type 2 diabetes, and is associated with fewer episodes of symptomatic hypoglycaemia, particularly nocturnal episodes.
