[The role of the DPP-4 inhibitor sitagliptin in the therapy of type 2 diabetes, in light of the new guidelines]


NOVEMBER 22, 2012

Lege Artis Medicinae - 2012;22(10-11)

[Type 2 diabetes has become a global public health problem, threatening the economies of all nations, as a consequence of rapid urbanisation, changing eating habits, sedentary lifestyle and obesity. Asian populations tend to develop diabetes at younger ages and lower body mass index compared with Caucasians. The latest guidelines of the American Diabetes Association and the European Association for the Study of Diabetes recommend lifestyle interventions as the first step for patients with newly diagnosed type 2 diabetes. The widely used metformin remains one of the first-line drugs for type 2 diabetes. If monotherapy alone does not achieve or maintain the target HbA1c level, addition of a second oral agent is recommended as a second step. The highly selective dipetidyl peptidase-4 inhibitor sitagliptin and metformin are efficient and well tolerable. The complementary effects of sitagliptin and metformin lead to an efficient, safe and long-term improvement in glycaemic control.]

[The sensor-augmented insulin pump and its use in clinical practice]


[Diabetes is one of the most common chronic diseases. Technological advances provide increasingly refined tools for clinicians to manage type 1 and type 2 diabetes. Continuous subcutaneous insulin infusion (CSII), also known as insulin pump, allows for a sophisticated delivery of basal as well as bolus insulin. Continuous glucose monitoring helps patients and clinicians understand and manage changes in blood glucose trends and minute-to-minute blood glucose variablitiy. The sensor-augmented insulin pump was created by the merging of these devices, which has been a revolutionary step towards self-regulatory, closed-loop insulin delivery or the creation of an artificial pancreas.]

[The prevalence of type 2 diabetes mellitus has recently dramatically increased worldwide. While many factors contribute to the startling data, including changes in the diagnostic criteria of glucose intolerance, increase of life expectancy, manifestation of diabetes at younger ages, and increased detection of unrecognized diabetes due to more efficient screening, the genuine, steep rise in the incidence of diabetes is explained by the increasing prevalence of obesity. Among the late complications of both diabetes and obesity, cardiovascular diseases are particularly important. Insulin resistance due to visceral obesity plays a central role in the pathomechanism of type 2 diabetes. In the prevention of both type 2 diabetes and obesity, non-pharmacological intervention such as life style changes should be considered first. Supplementary pharmacological treatment should target all cardiovascular risk factors.]

[Several questions of medical treatments in polycystic ovary syndrome]


[Polycystic ovary syndrome is an endemic disease, thus its treatment is of great importance. In polycystic ovary syndrome, metformin decreases androgen levels, improves menstrual irregularity, hirsutism, ovulation ratio, and the efficiency of lifestyle interventions on visceral obesity, endothelial function and LDL-cholesterol level. It seems plausible to suppose that metformin decreases the incidence of diabetes in this group of patients. Metformin is superior to oral contraceptives/antiandrogens in respect of its effect on triglyceride level and insulin sensitivity, however, it is less effective in decreasing androgen levels, normalisation of the menstrual cycle and supposedly in the prevention of endometrial cancer. Metformin therapy improves fertility, however, when infertility is the main problem, it is not indicated as the primary treatment. In this case, ovulation induction, ovary drilling, as well as in vitro fertilization are warranted that can be supported by metformin therapy is some cases.]

[Incretin based therapies from a clinician’s view]

KIS János Tibor

[The incretin based therapies give new and promising opportunities in the care of type 2 diabetic patients. Right now two kinds of incretinmimetics and three incretinenhancers are available in Hungary. There are more and more agents and more industrial products. There are several publications about the advantages of these products, but only a few data can be found about the comparison of them. The author tries to evaluate the incretin based therapies, and tries to help the clinicians choose the right one.]


[Bone metabolism and the 10-year probability of hip fracture and a major osteoporotic fracture using the country specific FRAX algorithm in men with type 2 diabetes mellitus]


[Objectives: Was to evaluate 10-year probability of hip fracture and a major osteoporotic fracture using the FRAX algorithm, vitamin D status, bone mineral density (BMD) and biochemical markers of bone turnover in men over 50 years of age with type 2 diabetes (T2DM). We compared FRAX-predicted 10-year fracture probability, levels of 25-hydroxyvitamin D (25-OH-D), markers of bone turnover and bone mineral density at L1-L4 (LS) and femur neck (FN) in 68 men with T2DM with an age- and gender-matched group (n=68). The mean (range) age of the T2DM group was 61.4 (51-78) years. The prevalence of hypovitaminosis D (25-OH-D <75 nmol/L) was 59%. The mean (range) FRAX hip fracture and FRAX major osteoporotic fracture was 0.7 (0-2.8)% and 3.2 (0-8.5)%, respectively. BMD at the FN (0.974 gm/cm2 vs. 0.915 gm/cm2; p = 0.008) and LS (1.221 gm/cm2 vs. 1.068 gm/cm2; p < 0.001) was significantly higher in the T2DM cohort as compared to the healthy age matched males. 25-OH-vitamin D (67.7 nmol/L vs.79.8 nmol/L; p < 0.001), crosslaps (0.19 μg/L vs. 0.24 μg/L; p = 0.004) and osteocalcin (13.3 μg/L vs. 15.7 μg/L; p = 0.004) were significantly lower in the T2DM group. There was no difference in FRAX-related fracture probability between the two groups. The increased BMD in T2DM and the lack of inclusion of T2DM as a risk factor in the FRAX algorithm are probable explanations for the discordance between literature-observed and FRAX-related fracture probabilities.]

[Switching from human basal insulin to once daily insulin detemir in type 2 diabetic patients treated by basal-bolus regimen - Results from the LEONCET2, an observational, prospective, multicenter study]

[Insulin analogues have been developed in order to overcome some drawbacks of human insulins. Switching from a human insulin-based basal- bolus regimen to once daily detemir could result in improved metabolism and increased safety of the therapy. We assessed the effects of switching from human NPH-insulin to once daily detemir insulin in patients with type 2 diabetes mellitus treated with a basal-bolus insulin regimen. We evaluated the data of 1,474 patients with diabetes (age: 59.1±9.8 years, body weight 89.6±8.6 kg, BMI 31.6±5.4 kg/m2) in an observational, prospective, 24-week, multicenter study. All patients were treated with a basal-bolus regimen consisting of human NPH as basal insulin and a human or analogue insulin as bolus insulin. After enrollment, patients received once daily detemir insulin instead of NPH-insulin, while treatment with bolus insulin was continued. Patients were examined at weeks 12 and 24. By week 24, the mean HbA1c value, irrespective of BMI-categories, decreased significantly (p<0.0001) from 8.63±1.01% by 0.79±0.63%. Fasting blood glucose level decreased from 8.86±1.78 mmol/l to 7.09±1.31 mmol/l; p<0.0001). The target level of HbA1c (<7.0%) was reached by 194 patients (13.1%). The patients’ body weight decreased significantly by week 12 (-0.69±2.00 kg; p<0.0001) and by week 24 (-1.28±2.80 kg; p<0.0001). The changes were more pronounced in higher than in lower BMI-categories (p for trend <0.0001). The mean daily doses of basal insulin were increased from 0.28 IU/kg to 0.33 IU/kg while those of bolus insulins were not changed. The rate of severe hypoglycaemic events decreased significantly (p=0.048) from 2.95 [daytime 1.02, nocturnal 1.93] to 0.06 [daytime 0.04, nocturnal 0.02] episodes/patient-year. In patients with type 2 diabetes mellitus treated with basal-bolus regimen, switching from human basal insulin to once daily insulin detemir results in a significantly improved metabolism, as well as fewer hypoglycaemic events and decreased body weight. Nevertheless, the low rate of patients reaching the glycaemic target implicates that some factors other than an appropriate basal insulin substitution have a role in achieving an optimal metabolic control.]
