Long-term micro- and macrovascular complications cause major morbidity and mortality in patients with type 2 diabetes mellitus. Up to the present it is not clear whether intensified or conventional insulin treatment is more effective to keep blood glucose concentrations close to the normal range. In the present trial 90% (n = 117) of all insulin-treated type 2 diabetic patients aged 16 to 60 years and living in the city of Jena (100,247 inhabitants), Thuringia, Germany were examined. Fourty patients (34%) were on intensive insulin therapy (ICT, > or = 2 injections of normal- and > or = 1 injection of NPH-/mixed-insulin/day, > or = 1 insulin-dose adjustments/week, > or = 2 blood-glucose self-tests/day) and 77 patients (66%) were on conventional insulin therapy (CIT). Patients with ICT had more injections/d (4.3 +/- 0.7 vs CIT 2.4 +/- 0.7, p < 0.001), more insulin-dose adjustments/week < or = 11.5 +/- 8.2 vs 2.2 +/- 5.2, p < 0.001) and more blood-glucose self-tests/week (25.2 +/- 5.7 vs 9.6 +/- 8.8, p < 0.001). Patients with ICT had higher insulin doses (0.71 +/- 0.32 vs 0.47 +/- 0.2 IU/kg body wt/d, p < 0.001), were younger (50.5 +/-6.7 vs 54.0 +/- 5.9 years, p = 0.004) and they had a non-significant tendency to a better HbAlc (8.7 +/- 2.2 vs 9.2 +/- 2.0%, p = 0.23, HPLC, Diamat, normal range 4.4-5,9%). There was a negative correlation between HbAlc and the frequency of blood-glucose self-tests/week (r = -0.23, p = 0.019) and the number of insulin-dose adjustments/week (r = -0.33, p < 0.001). There were no differences between the groups as regards body-mass index (29.7 +/-4.9 vs 28.0 +/- 4.5 kg/m2, p = 0.06), diabetes duration (12.3 +/- 6.9 vs 12.2 +/- 7.5 years, p = 0.96), duration of insulin therapy (4.2 +/-3.5 versus 4.5 +/- 4.8 years, p = 0.67), incidence of acute complications (severe hypoglycaemia, diabetic coma), prevalence of retino-, nephro- and neuropathy (assessed according to Young et al.) and education or socio-economic factors. Also, in respect of quality of life and treatment satisfaction, assessed with standardized questionnaires according to Bradley et al. and Lewis et al., there were no differences between the two groups. In conclusion, in type 2 diabetic patients, ICT seems to be indicated in a second step in "problem-patients" with bad metabolic control under CIT and/or individual's need for more flexibility. Perhaps, in these patients ICT leads to an improvement in the quality of metabolic control.

In people with type 2 diabetes (T2DM), hyperglycemia has a negative impact on cardiac function and cardiovascular risk. Beneficial effects of improved postprandial glycemic control have been shown for cardiovascular risk only. To demonstrate these beneficial effects on myocardial function, we investigated well-controlled T2DM patients on three insulin regimens with different impact on postprandial glucose control. For 24 months, 61 T2DM participants in a randomized study had either conventional therapy (CT) with human premixed insulin b.d. (n=20), intensified therapy (ICT) with Lispro at meals and NPH at bedtime (n=24), or supplementary therapy (SIT) with human regular insulin at meals (n=17). Metabolism and cardiovascular function were assessed before and 2 hours after a standardized carbohydrate breakfast (48 g) using tissue Doppler to measure diastolic myocardial function (E'). Age, BMI, dose of insulin, cardiovascular disease, and medication were comparable between the groups. Hb1Ac was comparable with CT, ICT, and SIT (6.6+/-0.6, 6.2+/-0.6, and 6.4+/-0.7%) and so was fasting glucose. Post-meal glucose increment was 60+/-45 mg/dl with CT, but 15+/-52 and 8+/-58 mg/dl with ICT and SIT (p<0.006). E' was significantly lower (p<0.03) with CT (6.8+/-1.0 cm/s) vs. ICT (7.7+/-1.6) and SIT (7.8+/-1.2 cm/s), and correlated with post-meal glucose (r=-0.2644, p<0.046). Intima-media thickness and arterial stiffness parameters were higher in CT (p<0.04). In T2DM patients, the long-term insulin regimens CT, ICT, and SIT achieved overall good metabolic control with significant differences, however, in postprandial glucose increments. The regimens achieving better post-meal glucose control were associated with better myocardial/vascular function.

In contrast to the widely reported ethnic differences in prevalence, the incidence of type 2 diabetes was surprisingly similar (approximately 11%) among individuals from the different US ethnic groups in the Diabetes Prevention Program (DPP). Because DPP participants had impaired glucose tolerance (IGT) at baseline, we hypothesized that ethnic disparities are initiated at the pre-IGT stage during evolution of type 2 diabetes. The Pathobiology of Prediabetes in a Biracial Cohort (POP-ABC) is designed to test that hypothesis by tracking the natural history of early dysglycemia in a biracial cohort comprising offspring of parents with type 2 diabetes. The POP-ABC study has an enrollment target of 400 participants (200 African American, 200 Caucasian), aged 18-65 years, with at least 1 parent with type 2 diabetes. All subjects must have normal fasting glucose and/ or normal glucose tolerance, as determined by a 75-gram oral glucose tolerance test (OGTT). Subjects are recruited over approximately 3 years and followed for another 2 years, with repeated metabolic assessments. The latter include OCTT, body composition, indirect calorimetry, euglycemic clamp, beta cell function, and biochemistries. Repository specimens (DNA, RNA and proteome) are obtained for future studies. The primary outcome is the occurrence of prediabetes (ICT and/or impaired fasting glucose). The sample size provides 85% power to detect a hazard ratio of 1.75 between Black and White offspring in the primary outcome (alpha = .05). Secondary endpoints include behavioral, biochemical and socioeconomic predictors of dysglycemia. The POP-ABC study will elucidate the nosogeny of ethnic disparities in glucose dysregulation.
