Switching the basal insulin to insulin glargine 300 U/ml in people with type 2 diabetes under basal insulin supported oral therapy: Observational trial on effectiveness and safety.

AIMS: This study evaluated the effectiveness and safety of switching the basal insulin (BI) in a BI-supported oral therapy (BOT) to insulin glargine 300 U/ml (Gla-300) in adults with inadequately controlled type 2 diabetes (T2D). MATERIALS AND METHODS: This was a non-interventional, multicentre, prospective 12-month study, conducted in Germany, Austria and Switzerland. The study documented people with T2D with glycated haemoglobin (HbA1c) between 7.5% and 10.0%, currently treated by a non-Gla-300 BOT regimen, after the physician had decided to switch the BI to Gla-300. Primary endpoint was the proportion of patients achieving the fasting plasma glucose (FPG; ≤110 mg/dl) target. RESULTS: In total, 1194 participants comprised the full analysis set, of which 793 completed documentation of 12 months Gla-300 treatment (FAS-M12). The main previous BI was insulin glargine 100 U/ml (Gla-100; 47.2%). Twelve months after switching to Gla-300, 27.0% of FAS-M12 participants achieved the FPG target and 44.8% their individualized HbA1c target. The greatest FPG target achievements were seen in previous Gla-100 (29.3%), and greatest HbA1c target achievements in previous insulin detemir users (57.7%). The mean FPG decreased by -36.3 ± 51.2 mg/dl to 135.5 ± 36.9 mg/dl and mean HbA1c by -0.79 ± 1.01% to 7.45 ± 0.94%. Symptomatic and nocturnal hypoglycaemia incidence significantly decreased over 12 months of Gla-300 treatment. Body weight remained unchanged. CONCLUSIONS: Switching the BI to Gla-300 in a BOT regimen improved metabolic control and treatment satisfaction in a substantial proportion of patients with T2D and inadequate target achievement within 12 months in clinical practice with a decreased risk of symptomatic and nocturnal hypoglycaemia and without weight gain.

Effectiveness and safety of insulin glargine 300 U/mL in insulin-naïve patients with type 2 diabetes after failure of oral therapy in a real-world setting.

AIM: To evaluate the effectiveness and safety of initiating basal insulin-supported oral therapy (BOT) with insulin glargine 300 U/mL (Gla-300) in patients with type 2 diabetes inadequately controlled on oral antidiabetic drugs (OADs). MATERIALS AND METHODS: This non-interventional, multi-centre, prospective 52-week study, conducted in Germany and Switzerland, documented patients with type 2 diabetes with an HbA1c of between 7.5% and 10.0%, currently treated with OADs, after the physician had decided to start a BOT regimen with Gla-300. The primary endpoint was the rate of achievement of the individualized predefined HbA1c target. RESULTS: Of 1748 patients included, 1153 comprised the full analysis set, of whom 721 completed documentation of 12 months of Gla-300 treatment. Twelve months after starting Gla-300, 49.9% achieved their individualized HbA1c target, and 61.1% achieved either their HbA1c target or a fasting plasma glucose (FPG) of ≤110 mg/dL. Mean HbA1c decreased by -1.22% ± 1.05% to 7.28% ± 0.92% and mean FPG by -51.5 (±48.63) mg/dl to 132.9 ± 33.0 mg/dL. Median duration of HbA1c target achievement was 341 days and probability to remain on target after 6 months was 81%. Hypoglycaemia incidence and rates remained low after 12 months of Gla-300 treatment; no severe or severe nocturnal hypoglycaemia was observed. Body weight remained unchanged. CONCLUSIONS: Starting a BOT regimen with Gla-300 allowed about 60% of 721 German and Swiss patients with inadequately controlled type 2 diabetes to achieve glycaemic control within 12 months in daily clinical practice. Glycaemic control was achieved without weight gain or increased risk of nocturnal or severe hypoglycaemia.

Predictors of treatment response in type-2 diabetes patients initiating basal-supported oral therapy with insulin glargine 100 U/mL: A sub-analysis of the Titration and OPtimisation (TOP) registry.

The aim of this study was to identify predictors of long-term response to the initiation of basal-supported oral therapy (BOT) with insulin glargine (IGlar-100). Patients from the observational TOP registry were grouped based on those who had achieved (responders) and those who had not achieved (non-responders) their HBA1c target and/or FBG ≤110 mg/dL 12 months after IGlar-100 initiation. Independent predictors of treatment response were identified by regression analysis. Data for 2444 patients were analysed (responders, n = 1610; non-responders, n = 834). Although the IGlar-100 dose increase over 12 months was larger for non-responders (+12.83 vs +9.46 U/d; P < 0.0001), the corresponding decrease in HbA1c was smaller (-0.88% vs -1.57%). Independent predictors of response included lower BMI (OR, 0.97; 95% CI, 0.95-1.00), lower FBG (OR, 0.98; 95% CI, 0.97-0.98) and HbA1c values at baseline (OR, 0.24; 95% CI, 0.18-0.31), a less ambitious HbA1c target (OR, 5.07; 95% CI, 3.37-7.63) and bedtime administration of IGlar-100 (OR, 1.55; 95% CI, 1.12-2.14). In conclusion, HbA1c was the clinically most significant baseline characteristic predictive of response to BOT. This may suggest an advantage of IGlar-100 initiation prior to excessive hyperglycaemia escalation.

Titration and optimization trial for the initiation of insulin glargine 100 U/mL in patients with inadequately controlled type 2 diabetes on oral antidiabetic drugs.

For patients with type 2 diabetes mellitus (T2DM) and inadequate glycaemic control, addition of basal insulin is recommended, but titration and optimization of basal insulin therapy in primary care is not well understood. We conducted an observational trial in 2470 patients with T2DM who initiated insulin glargine 100 U/L (Gla-100) on top of oral antidiabetic drugs. Physicians were free to choose either a "Davies," "Fritsche" or "individual" titration algorithm. We found that fasting blood glucose (FBG) and glycated haemoglobin (HbA1c) levels were effectively reduced by Gla-100; 65.9% of patients achieved the primary endpoint (FBG ≤6.1 mmol/L (110 mg/dL) or an individual HbA1c target). There were no significant differences in efficacy and safety between the algorithms used. The mean FBG decreased by 3.2 mmol/L (59 mg/dL) over 12 months, while the mean HbA1c decreased by 15.3 mmol/mol (1.4%)%. From a starting dose of 11.7 U/d, the Gla-100 dosage was 22.8 U/d at 12 months, with similar values in each group. Rates of hypoglycaemia were low and did not differ by titration algorithm. We conclude that Gla-100 was effective at reducing FBG and HbA1c, independent of the titration algorithm, but observed that algorithms were inconsistently applied in clinical practice.

Effectiveness and Safety of Insulin Glulisine When Initiating Supplementary Prandial Insulin Treatment (SIT) in Insulin-Naïve Patients with Type 2 Diabetes: The Observational IGLU-SIT Study.

INTRODUCTION: The IGLU-SIT study documented the effectiveness of initiating supplementary prandial insulin treatment (SIT) with insulin glulisine after failure of oral antidiabetic drugs alone in patients with type 2 diabetes (T2DM) in a real-world setting in Germany. METHODS: The IGLU-SIT study was an open-label, prospective, multicentre, non-interventional study with an observation period of 12 ± 1 months. The primary objective was to determine the proportion of patients reaching their pre-defined glycosylated haemoglobin (HbA1c) goal at 3, 6, 9 and 12 months. Selected secondary objectives were absolute change in HbA1c, a 7-point blood glucose profile, and rate of hypoglycaemia. Data were evaluated overall and by age group (< 65, 65-74 and ≥ 75 years). RESULTS: Overall, 215 patients with T2DM were observed in 64 centres. Baseline HbA1c was 8.3%, and mean HbA1c target was 6.8% (baseline 8.1% and target 6.9% in patients ≥ 75 years). Individual HbA1c target attainment in patients peaked at 38.9% (95% confidence interval [CI] 32.1-46.1%) after 12 months; this was 45.9% in patients aged ≥ 75 years. The mean HbA1c reduction was 1.12 ± 1.05% (p < 0.0001) with only minor differences by age group. A 7-point blood glucose profile revealed significant reductions (p < 0.0001) at all time-points. The rate of confirmed symptomatic hypoglycaemia was 2.2% (95% CI 0.7-5.1) during the 12-month follow-up; rates were increased in patients aged ≥ 75 years (7.0%; 95% CI 1.5-19.1) as were the rates of adverse events (17.8 vs. 6.1%). CONCLUSION: Initiating SIT with insulin glulisine is an appropriate treatment option in patients whose T2DM is insufficiently controlled. Particular attention should be paid to elderly patients in whom higher attainment rates of treatment target were associated with adverse events.

Effectiveness and Safety of Switching Rapid-Acting Insulins to Insulin Glulisine in Patients with Diabetes: The Observational IGLU-S Study.

INTRODUCTION: The IGLU-S study assessed the effectiveness of insulin glulisine after switching from human insulin/other rapid-acting insulin analogues in patients with type 1 diabetes (T1DM) and type 2 diabetes (T2DM) in a real-world setting in Germany. METHODS: Open-label, prospective, multicentre, non-interventional study in Germany. The primary outcome was proportion of patients reaching pre-defined glycosylated haemoglobin A1c (HbA1c) goal at 3, 6, 9 and 12 months. Secondary outcomes included absolute changes in HbA1c, rate of hypoglycaemia and 7-point blood glucose profiles. RESULTS: Overall, 432 (55 T1DM, 377 T2DM) patients were enrolled. Baseline HbA1c was 8.2% (T1DM) and 8.3% (T2DM); individual HbA1c targets were 6.8% and 6.9%, respectively. After insulin glulisine introduction, the proportion of patients achieving their individual HbA1c increased to 43.6% (T1DM) and 39.6% (T2DM) of patients at 12 months. At 12 months, mean HbA1c was reduced by 0.86 ± 1.03% (p < 0.0001) in T1DM and 1.01 ± 1.02 (p < 0.0001) in T2DM. The 7-point blood glucose profile showed a significant reduction in patients with T2DM (p< 0.0001) and a non-significant reduction in T1DM patients. Confirmed symptomatic hypoglycaemia was 5.7% (T1DM) and 1.6% (T2DM). There were no cases of severe hypoglycaemia. CONCLUSION: Switching prandial insulin to insulin glulisine resulted in improved effectiveness with 43.6% of T1DM and 39.6% of T2DM patients reaching their individual pre-defined HbA1c target within 1 year. Switching was safe and was associated with a low rate of hypoglycaemia and adverse events. TRIAL REGISTRATION: https://awbdb.bfarm.de ; Identifier: 6818; Date of registration: 23.06.2016.

Titration of insulin glargine 100 U/mL when added to oral antidiabetic drugs in patients with type 2 diabetes: results of the TOP-1 real-world study.

AIMS: Adequate insulin titration is crucial for optimal glycaemic control in type 2 diabetes (T2D). We aimed to explore the factors and outcomes associated with titration of glargine 100 U/mL (Gla-100) in patients uncontrolled on oral antidiabetic drugs (OAD) and initiating insulin therapy. METHODS: Patients from the Titration and Optimization (TOP)-1 registry were stratified by the magnitude of Gla-100 up-titration during the first month (no [< 1 Units (U)/day (d)], minimal [≥ 1 and < 5 U/d], moderate [≥ 5 and ≤ 8 U/d] and strong [> 8 U/d]). The primary endpoint was a fasting blood glucose (FBG) ≤ 110 mg/dL on ≥ 2 occasions and/or individual HbA1c target by 12 months. RESULTS: Of 2308 patients, 905, 715, 409 and 279 underwent no, minimal, moderate and strong titration, respectively. Age decreased across increasing titration groups (p = 0.02) while body mass index (BMI) (p < 0.0001), FBG (p < 0.0001), and HbA1c (p < 0.0001) increased. At 12 months, the proportions of patients achieving the primary endpoint were comparable across groups (66.1% overall), though a smaller proportion of no titration patients met both their individual HbA1c target and FBG ≤ 110 mg/dL compared to moderate and strong titration patients (20.1% vs. 27.2% and 26.2%, p = 0.033 and 0.023, respectively). HbA1c was also comparable, though FBG was higher in the no titration group (126.2 vs. 122.6, 121.5 and 120.9 mg/dL, p < 0.02). A similar, small reduction in body weight occurred in all groups; hypoglycaemia rates were comparable across groups. CONCLUSIONS: In real-world, titration of Gla-100 during the first month appears to coincide with a number of baseline factors. Insulin dose to meet HbA1c and FBG targets remains suboptimal in the majority of T2D patients.

Austrian Experience with Lixisenatide Under Real-Life Conditions: A Prospective Observational Study.

INTRODUCTION: Lixisenatide has been studied extensively in randomized clinical trials; however, data on its use in the real-life practice are scarce. METHODS: This study was a prospective, 26-week, multicenter, observational study conducted in Austrian diabetes centers and office-based practices to evaluate efficacy and safety of lixisenatide under real-life conditions in patients with type 2 diabetes. RESULTS: Out of 144 patients (mean BMI 36.4 kg/m2, disease duration 12.4 years), 113 completed the documentation at 6 months and 42% received basal insulin with or without oral antidiabetic drugs. The HbA1c declined from 8.7% (72 mmol/mol) to 7.9% (63 mmol/mol) and at study end 24.8% of the patients reached an HbA1c level below 7%. Fasting and postprandial glucose after lixisenatide administration were reduced by 27 ± 58 mg/dl and 45 ± 67 mg/dl, respectively. At study end body weight (- 4.5 ± 5.4 kg), triglycerides (- 10.8 ± 105 mg/dl), systolic blood pressure (- 4.8 ± 17.1 mmHg), and LDL cholesterol (- 3.7 ± 25 mg/dl) were reduced. The most commonly reported adverse events were gastrointestinal disorders (18.8%). Forty-three patients (30%) discontinued prematurely, mostly caused by lack of efficacy, occurrence of gastrointestinal disorders, and missing reimbursement. The average dose of insulin decreased slightly by 1.5 units (from 29.4 to 27.9). CONCLUSION: Lixisenatide demonstrated a similar efficacy and safety profile under real-life conditions as previously shown in randomized clinical trials. FUNDING: sanofi-aventis GmbH Austria.

HbA1c target achievement in the elderly: results of the Titration and Optimization trial for initiation of insulin glargine 100 U/mL in patients with type 2 diabetes poorly controlled on oral antidiabetic drugs.

Objectives: To identify real-world, age-related trends in the use of insulin glargine 100 U/mL (Gla-100) as part of basal-supported oral therapy (BOT). Research design and methods: The prospective, observational Titration and Optimization registry enrolled patients with poorly controlled type 2 diabetes mellitus initiated on Gla-100 BOT. The primary outcome was the proportion of patients with capillary fasting blood glucose (FBG) ≤110 mg/dL on ≥2 occasions and/or who met their individual HbA1c target within 12 months. Results: 2462 patients were analyzed (<65 years: n=1122; 65-74 years: n=771; ≥75 years: n=569). Diabetes duration (6.8, 8.9, and 11.2 years, p<0.0001) and proportion of women (40.7%, 47.9%, and 55.7%, p<0.0001) increased with age. Baseline HbA1c was highest in <65-year-olds (8.6% vs 8.4% and 8.5%, p<0.0001). Gla-100 up-titration until 12 months was highest in <65-year-olds (+11.6 U/day), compared with 65-74 (+10.2 U/day) and ≥75 years (+8.8; p<0.0001) but similar by units per kilogram, as was the decrease in FBG (<65: -64.1 mg/dL; 65-74: -56.1 mg/dL; ≥75: -53.4 mg/dL) and HbA1c (<65: -1.47%; 65-74: -1.31%; ≥75: -1.22%, p<0.0001). At 12 months, 65.9% of participants met the primary endpoint, with no significant difference between age groups. The proportion achieving their individual HbA1c target was lower for <65-year-olds (46.0% vs 54.3% and 54.7%; p<0.02). Symptomatic hypoglycemia incidence was more common in the ≥75-year-old group (3.4% vs 1.4% and 1.4%; p=0.0126). Conclusions: BOT with Gla-100 results in similar improvements of glycemic values with low risk of hypoglycemia across age groups. Given the link between HbA1c and long-term cardiovascular risk, ensuring appropriately stringent target-setting, intensification of basal insulin and making sure hypoglycemia is avoided is of paramount importance.

Changes in proinflammatory cytokine activity after menopause.

There is now a large body of evidence suggesting that the decline in ovarian function with menopause is associated with spontaneous increases in proinflammatory cytokines. The cytokines that have obtained the most attention are IL-1, IL-6, and TNF-alpha. The exact mechanisms by which estrogen interferes with cytokine activity are still incompletely known but may potentially include interactions of the ER with other transcription factors, modulation of nitric oxide activity, antioxidative effects, plasma membrane actions, and changes in immune cell function. Experimental and clinical studies strongly support a link between the increased state of proinflammatory cytokine activity and postmenopausal bone loss. Preliminary evidence suggests that these changes also might be relevant to vascular homeostasis and the development of atherosclerosis. Better knowledge of the mechanisms and the time course of these interactions may open new avenues for the prevention and treatment of some of the most prevalent and important disorders in postmenopausal women.

Resource utilisation and costs in patients with type 2 diabetes mellitus treated with insulin glargine or conventional basal insulin under real-world conditions in Germany: LIVE-SPP study.

OBJECTIVE: To assess and compare the total costs relevant to diabetes care in patients with type 2 diabetes mellitus (T2D) treated at specialised diabetes practices with either insulin glargine- or conventional basal insulin (neutral protamine Hagedorn [NPH])-based therapies from the German statutory health insurance (SHI) perspective. METHODS: The Long Acting Insulin Glargine Versus NPH Cost Evaluation in Specialised Practices (LIVE-SPP) study is an observational, retrolective, multicentre longitudinal cost comparison in adults with T2D. Costs were evaluated from the German SHI perspective based on official 2005 prices. Average total costs per patient for insulin glargine-versus NPH-based therapies were compared using multivariate general linear modelling. Sensitivity analyses were performed by varying the main cost factors by +/- 25%. RESULTS: Patients (n=1,024, 512 patients per cohort) were on average 62 years of age, with an average 8-year diabetes history at study start. The average unadjusted total annual costs per patient were euro 1,868.41 (95% CI 1,744.27-1,992.56) for insulin glargine-based vs. euro 2,063.72 (95% CI 1,922.91-2,204.54) for NPH-based therapies. Average adjusted total annual costs per patient between insulin glargine- (euro 1,241.13) and NPH-based therapies (euro 1,607.86) were statistically significantly different (p=0.0004). The economic advantage for insulin glargine-based therapies resulted mainly from fewer blood glucose measurements and other diabetes-related materials (e.g. needles). The savings remained stable in one-way sensitivity analyses. CONCLUSIONS: The LIVE-SPP study suggests that insulin glargine-based therapies may offer an economic advantage over NPH-based therapies.

Titration of basal insulin or immediate addition of rapid acting insulin in patients not at target using basal insulin supported oral antidiabetic treatment - A prospective observational study in 2202 patients.

AIM: Optimal treatment intensification strategies in patients with type-2 diabetes mellitus (T2DM) receiving basal insulin supported oral antidiabetic therapy (BOT) remain controversial. The objective of the present study was to compare outcomes of BOT-intensification by either the uptitration of long-acting insulin glargine or by the immediate addition of a rapid acting insulin analogue (RAIA). METHODS: This was a prospective, observational, 24-week study in T2DM patients with BOT using insulin glargine and baseline glycated hemoglobin (HbA1c) between 7.0 and 8.5%. Patients were stratified by their physicians to one of the following treatment intensification strategies: Basal insulin titration to target with discretionary subsequent addition of RAIA at weeks 12 or 24 (GLAR), or immediate addition of RAIA at baseline (GLARplus). RESULTS: A total of 3266 patients were prescreened of whom 2202 fulfilled the selection criteria. Of these, 1684 patients were documented in the GLAR group and 518 in the GLARplus group. In the GLAR group, in 91 (5.5%) and 21 patients (1.3%) RAIA was added at weeks 12 and 24, respectively. The groups displayed similar baseline characteristics; except, mean diabetes duration was slightly shorter in the GLAR group (8.7 vs. 9.4 years). During the study, insulin glargine dose was increased from 18.7 to 26.4U (plus 7.7U) in GLAR and from 24.9 to 27.3U (plus 2.4U) in GLARplus patients. Mean RAIA dose was 9.6±4.7U at the final visit. After 24 weeks, HbA1c was reduced by 0.8 and 0.9% in the GLAR and GLARplus groups, respectively (both p<0.001). An HbA1c of ≤7.0% was achieved in 49.2% of GLAR and 48.5% of GLARplus patients. In both groups, we observed improvements in cardiovascular risk factors such as lipids and blood pressure. The rates of symptomatic (1.6 vs. 1.7%) and severe (0.18 vs. 0.19%) hypoglycemic episodes were low and comparable in both groups. CONCLUSION: These findings provide evidence that treatment intensification in patients with type 2 diabetes not at glycemic target on BOT with insulin glargine is equally safe and effective using either long-acting insulin titration alone or the addition of a rapid-acting insulin analogue.

The role of limited joint mobility in diabetic patients with an at-risk foot.

OBJECTIVE: To assess the role of limited joint mobility (LJM) in causing abnormal high plantar pressures in the forefoot of diabetic patients with an at-risk foot. RESEARCH DESIGN AND METHODS: A total of 70 type 1 or type 2 diabetic patients and 30 control subjects participated in this cross-sectional study. Thirty-five diabetic patients with an at-risk foot, defined as a foot with neuropathy but without ulceration or previous ulceration, and 35 diabetic control subjects without neuropathy were selected for the subgroups. Joint mobility was assessed in the foot at the ankle and metatarsophalangeal I (first MTP) joints. Using the FastScan plantar pressure analyzer, the pressure-time integrals (PTIs) as dynamic variables were measured in each foot. The clinical assessment included standard measures of peripheral neuropathy. RESULTS: The mobility at the ankle and first MTP joint were significantly reduced in the foot-at-risk group compared with the diabetic control group and the control subjects (P < 0.0001). The PTIs were significantly higher in the foot-at-risk group compared with the two other groups (P < 0.0001). There was a strong inverse correlation between the mobility of the ankle or first MTP joint and the PTI of the diabetic patients (r = -0.67, P < 0.0001, and r = -0.71, P < 0.0001, respectively). The vibration perception threshold was positively correlated with the PTI of the diabetic patients (r = 0.44, P = 0.0001). CONCLUSIONS: Diabetic patients with an at-risk foot have reduced joint mobility and elevated PTIs on the plantar forefoot, placing them at risk for subsequent ulceration. Therefore, LJM may be a possible factor in causing high plantar pressures and may contribute to foot ulceration in the susceptible neuropathic at-risk foot.

Effectiveness and tolerability of treatment intensification to basal-bolus therapy in patients with type 2 diabetes on previous basal insulin-supported oral therapy with insulin glargine or supplementary insulin therapy with insulin glulisine: the PARTNER observational study.

BACKGROUND: Due to the progressive nature of type 2 diabetes mellitus (T2DM), antidiabetic treatment needs to be continuously intensified to avoid long-term complications. In T2DM patients on either basal insulin-supported oral therapy (BOT) or supplementary insulin therapy (SIT) presenting with HbA1c values above individual targets for 3-6 months, therapy should be intensified. This study investigated effectiveness and tolerability of an intensification of BOT or SIT to a basal-bolus therapy (BBT) regimen in T2DM patients in daily clinical practice. METHODS: This noninterventional, 8-month, prospective, multicenter study evaluated parameters of glucose control, occurrence of adverse events (eg, hypoglycemia), and acceptance of devices in daily clinical practice routine after 12 and 24 weeks of intensifying insulin therapy to a BBT regimen starting from either preexisting BOT with insulin glargine (pre-BOT) or preexisting SIT with ≥3 daily injections of insulin glulisine (pre-SIT). RESULTS: A total of 1,530 patients were documented in 258 German medical practices. A total of 1,301 patients were included in the full analysis set (55% male, 45% female; age median 64 years; body mass index median 30.8 kg/m(2); pre-BOT: n=1,072; pre-SIT: n=229), and 1,515 patients were evaluated for safety. After 12 weeks, HbA1c decreased versus baseline (pre-BOT 8.67%; pre-SIT 8.46%) to 7.73% and 7.66%, respectively (Δ mean -0.94% and -0.80%; P<0.0001). At week 24, HbA1c was further reduced to 7.38% and 7.30%, respectively (Δ mean -1.29% and -1.15%; P<0.0001), with a mean reduction of fasting blood glucose values in both treatment groups by more than 46 mg/dL. An HbA1c goal of ≤6.5% was reached by 17.9% (pre-BOT) and 18.6% (pre-SIT), and an HbA1c ≤7.0% by 46.1% (pre-BOT) and 43.0% (pre-SIT) of patients. During 24 weeks, severe as well as serious hypoglycemic events were rare (pre-BOT: n=5; pre-SIT: n=2; pretreated with both insulins: n=1). CONCLUSION: Intensifying glargine-based BOT or glulisine-based SIT to a BBT regimen in poorly controlled T2DM patients in daily routine care led to marked improvements of glycemic control and was well tolerated.

Four-year evolution of insulin regimens, glycaemic control, hypoglycaemia and body weight after starting insulin therapy in type 2 diabetes across three continents.

AIMS: It is of interest to understand how insulin therapy currently evolves in clinical practice, in the years after starting insulin in people with type 2 diabetes. We aimed to describe this evolution prospectively over 4 years, to assist health care planning. METHODS: People who had started any insulin were identified from 12 countries on three continents. Baseline, then yearly follow-up, data were extracted from clinical records over 4 years. RESULTS: Of the 2999 eligible people, 2272 were followed over 4 years. When starting insulin, mean (SD) duration of diabetes was 10.6 (7.8) years, HbA1c 9.5 (2.0)% (80 [22]mmol/mol) and BMI 29.3 (6.3)kg/m(2). Initial insulin therapy was basal 52%, premix 23%, mealtime+basal 14%, mealtime 8% and other 3%; at 4 years, 30%, 25%, 33%, 2% and 5%, respectively, with 5% not on insulin. Insulin dose was 20.2U/day at the start and 45.8U/day at year 4. There were 1258 people (55%) on their original regimen at 4 years, and this percentage differed according to baseline insulin regimen. HbA1c change was -2.0 (2.2)% (-22 [24]mmol/mol) and was similar by final insulin regimen. Hypoglycaemia prevalence was <20% in years 1-4. Body weight change was mostly in year 1, and was very variable, mean +2.7 (7.5)kg at year 4. CONCLUSION: Different insulin regimens were started in people with differing characteristics, and they evolved differently; insulin dose, hypoglycaemia and body weight change were diverse and largely independent of regimen.

Determinants and estimation of healing times in diabetic foot ulcers.

AIMS: To assess the wound size reduction and time course for healing and to establish equations to predict the time course of wound healing in neuropathic, neuroischemic, and ischemic diabetic foot ulcers. METHODS: This prospective study evaluates wound healing over at least a 10-week period in 31 Type 1 or Type 2 diabetic patients with plantar foot ulcers. Thirteen consecutive diabetic patients with neuropathic foot ulceration, 10 consecutive diabetic patients with neuroischemic ulceration, and 8 diabetic patients with peripheral occlusive vascular disease were selected for the study. All patients received identical ulcer wound care including use of proper footwear, non-weight-bearing limb support, use of appropriate antibiotics, debridement, tight control of serum glucose levels, and careful monitoring of the ulcer. Ulcer healing was assessed by planimetric measurement of the wound area every second week until wound healing. The time course of wound healing was calculated by the daily wound radius reduction. RESULTS: The wound area (mean+/-S.E.) in the patients with neuropathic foot ulceration was 61.2+/-17.1 at the beginning and 3.2+/-1.5 mm(2) after 70 days (P=.005). The wound radius decreased by 0.045 mm (95% confidence interval [CI] 0.039-0.055) per day, with most of the wound healing being achieved between the first and seventh week of ulcer care. The average healing time was 77.7 (95% CI 62-93) days. In the neuroischemic group, the initial average wound area was 26.6+/-7.0 mm(2), and 6.25+/-1.7 mm(2) after 10 weeks (P=.007). The wound radius reduction was 0.019 mm/day (95% CI 0.017-0.023) with an average healing time of 123.4 (95% CI 101-145) days. The diabetic patients with peripheral occlusive vascular disease had an average wound size of 32.6+/-13.1 at the beginning and 23.9+/-10.7 mm(2) after 70 days of ulcer care (P=.06). The daily wound radius reduction was 0.0065 mm (95% CI 0.0039-0.0091). Average ulcer duration was 133 (95% CI 116-149) days, but three of eight patients achieved no wound healing. CONCLUSIONS: Providing standard care, the time course of wound healing in diabetic foot ulcers is predominantly determined by etiologic factors, and less by wound size. Taking wound etiology and wound radius into account, the expected healing time can reliably be estimated in neuropathic and neuroischemic ulcers.

[Glutamic acid decarboxylase and tyrosine phosphatase-like IA-2 antibodies for diabetes classification in unselected diabetic patients]. / Antikörper gegen Glutamatdecarboxylase und Tyrosinphosphatase-ähnliches Protein IA-2 in der Klassifikation von unselektionierten Diabetespatienten.

BACKGROUND: The determination of glutamic acid decarboxylase and tyrosine phosphatase-like antibodies (GAD-AB and IA-2-AB) may be useful for the classification of diabetes, and in selected patient groups the measurement of these autoantibodies has been shown to be rather sensitive and specific. PATIENTS AND METHODS: In this study we examined the use of these antibody determination in a clinical setting of 157 diabetic outpatients recruited randomly from our diabetes clinic. The prevalence of the different antibodies was set in relation to the clinically classified diabetes type and to diabetes duration. RESULTS: Among the patients with a clinical diagnosis of type 1 diabetes, the GAD-AB were clearly positive in 44% and borderline positive in 10%, whereas the IA-2-AB were positive or borderline positive in 36% of these patients. The prevalence of positive autoantibodies declined with increasing duration of type 1 diabetes. Among the patients with clinically diagnosed type 2 diabetes, the GAD-AB were clearly positive in 25.2% and borderline positive in 13.1%, IA-2-AB were only found in 4.7%. Patients with a clinical diagnosis of type 2 diabetes but positive for GAD-AB could not clearly be identified as having latent autoimmune diabetes in adults (LADA), since some of them did not need insulin therapy up to 10 years after the diagnosis of diabetes. The prevalence of GAD-AB in type 2 diabetic/LADA patients did not depend on diabetes duration. CONCLUSION: We conclude that the determination especially of GAD-AB may be useful for the classification of diabetes in clinically unclear cases. The additional determination of IA-2-AB appears to provide only limited additional information.

Health economic evaluation of insulin glargine vs NPH insulin in intensified conventional therapy for type 1 diabetes in Germany.

OBJECTIVE: Basal insulin analogs are well established in the treatment of type 1 diabetes in Germany. However, little is known about their economic impact. The aim of this study for an adult population was to compare, from the perspective of the Statutory Health Insurance (SHI), the cost effectiveness of the long-acting insulin analog glargine (GLA) with intermediate-acting neutral protamine Hagedorn (NPH) insulin in basal bolus therapy, considering the interaction between glycemic control and the rate of hypoglycemia. METHODS: A validated discrete event simulation model was adapted to the German setting to project clinical and cost outcomes over 40 years. Resources were valued with German official prices in 2009/2010 Euros. Health-related disutilities were taken from UK sources. Patient characteristics and risk factors were partially extracted from German sources in a sensitivity analysis. RESULTS: In the base-case analysis, GLA was dominant as it increased life expectancy by 0.196 years and improved quality-adjusted life-years (QALYs) by 0.396 units while at the same time leading to savings of €5246 each per patient after 40 years compared to NPH. These results were robust in the sensitivity analyses. Monte Carlo simulation confirmed dominance of GLA in 70% (life-years gained) and 80% (QALYs gained) of the iterations. The price of GLA had the highest impact on savings. In extreme scenarios, incremental cost-effectiveness ratios increased up to €9576 per QALY gained. Limitations of the evaluation included no myocardial re-infarction(s) and no recurrent stroke(s), patient characteristics, risk factors, and disutilities from the UK due to scarce data in Germany, and that not all diabetes-related direct costs were included, namely insulin pens and blood glucose meters. CONCLUSION: GLA appears to be cost effective or even cost saving among type 1 diabetics with basal bolus therapy from the perspective of SHI compared to NPH depending on the scenario chosen.

Patient care at the 2010 Love Parade in Duisburg, Germany: clinical experiences.

BACKGROUND: The mass panic at the Love Parade 2010 attracted a great deal of public attention in Germany and abroad. The goals of this paper are to summarize the available data on the injured persons and their treatment, and to assess the preparations that should be made for such an eventuality and the acute measures that should be taken if it occurs. METHODS: Patient data from the Duisburg hospitals were subjected to a structured statistical analysis, and all of the measures taken were assessed by qualified evaluators on the basis of questionnaires, a consensus conference, and individual interviews of the clinical coordinators. RESULTS: A total of 250,000 persons took part in the Love Parade; 5600 patient contacts occurred at first-aid posts and 473 patients (mean age, 25.5 years; male:female ratio, 1.4:1) were treated in 12 hospital emergency rooms, 41.7% were admitted to the hospital. Among the admitted patients, 73% stayed in the hospital for less than 24 hours, and 41% signed out against medical advice; 62.2% had a surgical diagnosis, 40.6% a medical one, and 8.0% a psychiatric one (some patients had more than one diagnosis). 47.6% of the surviving patients were classified as mildly injured, 47.8% as moderately injured, and 4.0% as severely injured. Most medical activity was concentrated in three areas: the treatment of drug abuse, the care of many mild and moderate injuries, and Shock Room diagnostic assessment of patients potentially harboring serious injuries. Hospitals were subject to the highest strain 2 to 3 hours after the mass panic, at which time they received up to 20 new patients per hour. CONCLUSION: These data permit a detailed view of the medical care that was provided. In situations of this kind, the main problems can be dealt with through targeted and structured preparation and optimized emergency plans which consider both foreseeable and unforeseeable events. Priority must be given to rapid diagnostic assessment and clinical decision-making; the prerequisites for these are transparent institutional structures and clear assignments of responsibility.
