Abstract
Background Glucagon-like peptide-1 (GLP-1) receptor agonists are indicated for improvement of glycemic control in adults with type 2 diabetes. Cost is one aspect of treatment to be considered, in addition to clinical benefits, when selecting optimal therapy for a patient. The objective of this study was to estimate the average dose usage and real world daily cost of the GLP-1 receptor agonists, exenatide twice daily and liraglutide once daily, in Germany, the Netherlands, and the UK. Methods Administrative databases were used to source the data from longitudinal records of dispensed prescriptions. Data were extracted from the IMS Longitudinal Prescription database which captures details of prescriptions dispensed in pharmacies. Information on the dispensed quantity of each product was used to estimate average daily usage per patient. Daily dose usage was multiplied by the public price per unit to estimate daily cost. Results The dispensed volume in Germany corresponded to a mean dispensed daily dose of 16.81 μg for exenatide twice daily and 1.37 mg for liraglutide (mean daily cost €4.02 and €4.54, respectively). In the Netherlands, average dispensed daily doses of 17.07 μg and 1.49 mg were observed for exenatide twice daily and liraglutide (mean daily cost €3.05 and €3.97, respectively). In the UK, the mean dispensed volume corresponded to a daily usage of 20.49 μg for exenatide twice daily and 1.50 mg for liraglutide (mean daily cost £2.53 and £3.28, respectively). Conclusion Estimates of average daily dispensed doses of GLP-1 receptor agonists derived from pharmacy data in real world settings corresponded to the dosing recommendation of the summaries of product characteristics. Nevertheless, the mean daily cost of exenatide twice daily was lower than that of liraglutide in Germany, the Netherlands, and the UK. Such estimates can be used to inform health care decision-makers on the real world usage and cost of medications effective in achieving glycemic control in patients with type 2 diabetes.

Abstract
OBJECTIVES To describe the changes in resource utilization in seven European countries (Germany, Greece, Portugal, Romania, Sweden, Spain, and Turkey) and direct costs in four European countries (Germany, Spain, Sweden, and Greece) over the first 12 months of insulin treatment in patients with type 2 diabetes mellitus (T2DM). METHODS INSTIGATE and TREAT (2005-2010) were non-interventional, prospective, observational studies in patients with T2DM and initiating insulin for the first time. A 6-month retrospective data capture was conducted at baseline (insulin initiation) followed by prospective data collections at ∼3, 6, and 12 months. Statistical analyses were descriptive; estimated costs are presented as nominal values. RESULTS This study presents data for 1450 patients. Overall, in the first 6 months after insulin initiation, the use and cost of blood glucose monitoring and insulin increased, while the cost of oral diabetic medication decreased. Contributors to total direct costs differed between countries. Ranges of total mean direct costs over the 6-month period before insulin initiation were €489.10-€658.50 (Greece-Spain); 0-6 months after insulin initiation, €573.40-€1084.70 (Greece-Spain); and 6-12 months after insulin initiation, €495.80-€859.30 (Greece-Germany). Thus, the mean cost of treatment increased in all countries in the first 6 months after insulin initiation and then returned to baseline except in Germany. LIMITATIONS Overall, 15% of patients were lost to follow-up over 12 months. Costs were not pro-rated to account for variation of visits. Participating centres may not have been fully representative of all levels of care. CONCLUSIONS Contributors to total cost differed between countries, potentially reflecting local clinical practice patterns and insulin regimens. In each country, mean direct total costs of T2DM care increased during the first 6 months after insulin initiation and decreased thereafter.

Abstract
At the time of diagnosis of type 2 diabetes (T2D), patients already have varying degrees of beta-cell dysfunction and insulin resistance and the defects continue to deteriorate despite treatment. We examined insulin secretion impairment and insulin resistance in overweight patients with T2D who had metformin failure, with elevated HbA1c at maximal metformin dose. Patients (N = 1,039) were examined at entry to the European Exenatide (EUREXA) clinical trial of add-on exenatide versus sulphonylurea. Mean (±SD) age was 57 ± 10 years, and BMI was 32.4 ± 4.1 kg/m(2). All patients underwent an oral glucose tolerance test; HOMA-IR, HOMA-B, ∆I(30)/∆G(30), disposition index and pro-insulin/insulin ratio were evaluated in relation to stratified HbA1c levels (≤7.3, >7.3-8.2, >8.2%) and duration of diabetes (<3, ≥3-<6, ≥6 years) using non-parametric analysis of variance. Patients overall had a wide range of impaired insulin secretion (HOMA-B: median 50.4, interquartile range 32.8-78.8) and insulin resistance (HOMA-IR: 4.8, 3.0-7.4). With increasing HbA1c levels, there was a statistically significant decrease in HOMA-B (P < 0.001), ∆I(30)/∆G(30) (P = 0.003) and disposition index (P < 0.001), and increase in pro-insulin/insulin (P < 0.001) and HOMA-IR (P < 0.001). With increasing duration since diabetes diagnosis, there was a significant decrease in HOMA-B (P < 0.001), but no significant trend in HOMA-IR, ∆I(30)/∆G(30), disposition index or pro-insulin/insulin. Metformin failure in these patients was associated with beta-cell dysfunction to a greater extent than insulin resistance. Loss of the first-phase insulin release, indicated by a low ∆I(30)/∆G(30), would indicate that this patient cohort requires add-on therapy that can maintain beta-cell function.

Abstract
BACKGROUND The purpose of this study was to describe the resource use and associated direct costs of diabetes care for patients with type 2 diabetes mellitus in the 6 months before and after initiation of insulin therapy. METHODS INSTIGATE is a prospective, noninterventional, multicenter study of patients with type 2 diabetes who were initiating insulin for the first time as part of their usual care in 2006. The study was conducted in France, Germany, Greece, Spain, and the UK, and observed the course of diabetes therapy for up to 6 months. Direct medical costs were evaluated from the national health care system (third-party payer) perspective at 2006 prices. RESULTS Of the 1153 patients with type 2 diabetes, 1051 (91.2%) had follow-up visits in the 6 months after insulin initiation and were included in the cost analysis. In all countries in our study, mean total direct costs per patient increased in the 6-month follow-up period, compared with the 6-month period prior to insulin initiation, and ranged from €577 in Greece to €1402 in France. The incremental cost of adding insulin treatment ranged from €81 in France to €471 in Spain. CONCLUSION In all countries, the mean total direct cost of care for diabetes increased after starting insulin. The breakdown of total direct costs by expenditure category varied considerably across countries, reflecting differences in resource use patterns, prices of medical resources, and different health care systems.

Abstract
INTRODUCTION To examine changes in insulin regimens and glycemic control during the 24 months after initiation of insulin in patients with type 2 diabetes mellitus. METHODS Data were collected over a 24-month period from patients requiring insulin initiation as part of usual care, in a prospective, observational study. Changes in insulin regimens and hemoglobin A(1c) (HbA(1c)) were examined within countries (Germany, Greece, Spain) and overall. RESULTS Prandial insulin only was most commonly initiated in Germany, while basal or premixed formulations were initiated in Greece and Spain. In Germany, compared with Greece or Spain, the patients were slightly younger and had a shorter diabetes duration when initiating insulin. For patients overall, 76.1% did not change their insulin regimen between initiation and 24 months. The most obvious change was a shift from prandial to basal/bolus in Germany, with almost doubling of mean daily insulin dose; in Greece and Spain, more patients stopped using insulin and the trend to more complex regimens was not seen. Overall, mean (SD) HbA(1c) decreased from baseline (9.4 [1.7]%) to 6 months (7.2 [1.0]%), but with little further change through 24 months (7.2 [1.1]%). HbA(1c) change with basal/bolus insulin (-2.6 [2.0]%, baseline 10.1%) was greater than with basal only (-2.0 [1.8]%, baseline 9.3%). Mean HbA(1c) less than 7% was achieved and maintained over 24 months in Germany, but was not achieved at any time in Greece or Spain. CONCLUSIONS Within 24 months of insulin initiation, the majority of patients with type 2 diabetes remained on the same insulin regimen initially instigated, despite the well-established progressive loss of prandial and basal endogenous insulin secretion. Adequate glycemic control was best achieved where insulin dosage adjustments and insulin intensification took place.

Abstract
BACKGROUND Weight management is considered a key therapeutic strategy in type 2 diabetes mellitus. However, little is known about the impact of weight loss or body mass index (BMI) reduction on type 2 diabetes-related healthcare costs. OBJECTIVE The aim of this study was to estimate the economic impact of change in BMI among patients with type 2 diabetes mellitus from the Spanish healthcare system perspective. METHODS The ECOBIM study is an observational, non-interventional study in which data on BMI change and costs incurred by patients with type 2 diabetes were collected cross-sectionally and retrospectively for a 12-month period. Generalized linear mixed models were applied to estimate the effects of (i) BMI change in general (one-slope model); (ii) BMI gain and no BMI gain (two-slope model); and (iii) BMI gain and no BMI gain among obese and non-obese patients (four-slope model). RESULTS We studied 738 patients with a mean (SD) age of 66 (11) years and BMI of 30.6 (5.2) kg/m2. During the 12-month study period, 41.2% of patients gained BMI (BMI gainers) and 58.8% experienced either loss (52.2%) or no change (6.6%) in BMI (non-BMI gainers). One-unit gain (or loss) in BMI was significantly (p < 0.001) associated with a 2.4% cost increase (or decrease) [one-slope model]. Every unit gain in BMI was associated with a 20.0% increase in costs among BMI gainers while losing one unit was associated with an 8.0% decrease in costs among non-BMI gainers (two-slope model, p < 0.01). The economic benefit associated with reducing one BMI unit was 9.4% cost decrease in obese and 2.7% in non-obese patients (4-slope model). CONCLUSION An increase in BMI among patients with type 2 diabetes was associated with increased 1-year direct healthcare costs. A reduction in BMI was associated with appreciable short-term economic benefits, especially in obese patients.

Abstract
OBJECTIVES To examine insulin regimens and factors that affect glycaemic control at 6 months after initiation of insulin therapy in patients with type 2 diabetes mellitus. RESEARCH DESIGN AND METHODS Information on patients requiring insulin initiation as part of usual care was collected in a prospective, observational, open-label study in five European countries. Univariate and multiple regression analyses were used to investigate factors associated with HbA1c achieved at 6 months. RESULTS Mean HbA1c for all patients at baseline was 9.6 ± 1.8%. Long/intermediate-acting insulin only was most commonly initiated in France and Spain, while long/intermediate or pre-mixed formulations were initiated in Greece and UK. This was consistent with guidelines used in those countries and there was little change in insulin regimen at 6 months in these countries. In Germany, short-acting insulin only was favoured at baseline and there was a shift towards basal/bolus regimens at 6 months, which reflected the local guidelines for insulin initiation in Germany. Mean HbA1c reduction was greatest in Germany (-2.3%), which was the only country to achieve a mean of <7% at 6 months. In all countries, HbA1c achieved at 6 months was associated with baseline HbA1c. Differences between countries were seen for influence of factors such as BMI, duration of diabetes, insulin regimen, insulin dose and number of oral anti-diabetes drugs on HbA1c achieved. Explained variability for the factors ranged from 5.6% to 22.9%. CONCLUSIONS Differences in insulin regimen were observed between countries, and appeared to reflect the guidelines and treatment regimens used.

Abstract
AIM The Helping Evaluate Exenatide in overweight patients with diabetes compared with Long-Acting insulin (HEELA) study was designed to examine whether the glucagon-like peptide-1 (GLP-1) receptor agonist, exenatide, could improve HbA1c (< or =7.4%) with minimal weight gain (< or =1 kg) compared with insulin glargine. METHODS Patients [body mass index (BMI) >27 kg/m(2)] with elevated cardiovascular risk and type 2 diabetes inadequately controlled on two or three oral antidiabetes drugs (OADs) were randomized to add-on exenatide 5-10 microg b.i.d. (n = 118) or insulin glargine o.d. (titrated to target fasting plasma glucose < or =5.6 mmol/l; n = 117) for 26 weeks. RESULTS The study population had baseline mean (s.d.) age of 56.5 (9.1) years and BMI of 34.1 (5.3) kg/m(2), and 58.5% of patients were taking two OADs. Mean baseline HbA1c was 8.65 (0.68)% in the exenatide group and 8.48 (0.66)% in the insulin glargine group. The proportions of patients achieving the composite endpoint of HbA1c < or =7.4% with weight gain < or =1 kg were 53.4% for the exenatide group and 19.8% for the insulin glargine group (p < 0.001 for exenatide vs. insulin glargine). Exenatide and insulin glargine did not demonstrate a significant difference in HbA1c improvements [least square (LS) mean [s.e.m.]: -1.25 [0.09]% and -1.26 [0.09]% respectively; p = 0.924], but had divergent effects on body weight (-2.73 [0.31] vs. +2.98 [0.31] kg respectively, p < 0.001) after 26 weeks. There were more treatment-related adverse events with exenatide but a lower incidence of nocturnal hypoglycaemia, with no differences in overall or severe hypoglycaemia. CONCLUSIONS Additional treatment with exenatide resulted in significantly more overweight and obese patients with an elevated cardiovascular risk and type 2 diabetes achieving better glycaemic control with minimal weight gain compared with insulin glargine.

Abstract
AIM To describe the rationale for the European Exenatide (EUREXA) clinical study and describe the characteristics of the patient cohort. METHODS EUREXA is a multinational study of long-term effects of add-on exenatide vs. glimepiride in patients with type 2 diabetes and failure of diet/lifestyle plus metformin monotherapy. Metformin failure was defined as hemoglobin A1c (HbA1c) > or = 6.5% and patients were overweight/obese (BMI > or = 25 to < 40 kg/m(2)). The primary end point is time to failure of combination treatment, defined from HbA1c concentration according to current criteria. At baseline, an oral glucose tolerance test (OGTT) was performed, fasting blood was taken for lipid profile and patients were randomized to add-on exenatide (5 microg b.i.d. for 4 weeks then 10 microg b.i.d.) or glimepiride (1 mg/day titrated to maximum dose). RESULTS A total of 1039 patients were entered in the study, with mean (+/- s.d.) age 57.2 +/- 9.6 years, body mass index (BMI) 32.4 +/- 4.1 kg/m(2), duration of diabetes 5.6 +/- 4.5 years and HbA1c 7.4 +/- 0.7%. A history of cardiovascular disease (CVD) was present for 64.8% of patients overall and duration of diabetes was statistically significantly longer for patients with CVD than without (p = 0.010). Lipid abnormalities were reported for 48.9% of patients and 40.9% were taking at least one lipid-lowering medication. CONCLUSION Patients included in the EUREXA study had early failure of glucose control with metformin and presented typical features of type 2 diabetes: overweight/obesity and high prevalence of lipid abnormalities and CVD. In this population, the effects of exenatide vs. glimepiride will be evaluated over at least 2.5 years.

Abstract
OBJECTIVE To describe the characteristics at baseline of patients with type 2 diabetes mellitus who are initiating insulin. METHODS Prospective, observational multi-centre, open-label study in five European countries of patients with type 2 diabetes who were initiating insulin as part of their usual care. RESULTS A total of 1172 patients were enrolled, with mean age 63.3 years and body mass index 29.9 kg/m(2). The majority (90%) of patients were taking one or more oral anti-diabetic agents; the percentage not taking anti-diabetic medication in the previous four weeks was highest in Germany (23.4%) and Spain (15.1%). The prevalence of microvascular diseases (range: 16.1%-36.1%) varied considerably between countries but for macrovascular (30.4%-38.6%) and other diabetes-related diagnoses (72.6%-76.6%) such as hypertension and dyslipidaemia the differences were less pronounced. In Germany, reported use of lipid-lowering (26.7%) and anti-platelet (27.1%) therapies was much less than in other countries (ranges: 53.2%-78.1% and 48.3%-61.1%, respectively). The majority of evaluable patients in each country had demonstrated poor control over a long period of time. Prior to initiating insulin, the most recent mean (+/-SD) HbA1(c) was 9.58 +/- 1.81%, fasting plasma glucose was 12.18 +/- 4.32 mmol/L and 78.5% had metabolic syndrome. IDF targets for HDL- and LDL-cholesterol, and blood pressure were met in 76.8%, 33.1% and 18.9% of patients, respectively. CONCLUSIONS Insulin treatment was only initiated after HbA1(c) values were considerably higher than recommended in treatment guidelines for a sustained period of time.

Abstract
OBJECTIVE Initial GH-induced catch up growth is highly variable in short children born small for gestational age (SGA) and mainly influenced by age at start of therapy and GH dose. This study compared the first year growth-promoting effect of an individually adjusted GH dose (IAD) versus a fixed high GH dose (FHD) in pre-pubertal children born SGA with severe short stature. DESIGN This was a randomized, open-label, multi-center study. METHODS The FHD group received 0.067 mg/kg per day GH throughout the 12-month study. The IAD group initially received 0.035 mg/kg per day GH; at 3 months the Cologne growth-prediction model for first year change in height SDS was applied; if predicted change was <0.75, GH was increased to 0.067 mg/kg per day for the remaining 9 months, otherwise the initial dose was continued. RESULTS In the IAD group, 38 out of the 80 patients required the higher GH dose from month 3. From an ANCOVA for non-inferiority, mean difference in change in height SDS between IAD and FHD groups was -0.24 (95% confidence interval (CI) -0.35: -0.12), the CI for height SDS being above the pre-defined non-inferiority margin of -0.5. GH dose reductions due to IGF-I SDS >0.5 and IGFBP-3 SDS <-0.5 were performed in 4/99 FHD patients, but none of the IAD group patients. Safety data were similar between groups. CONCLUSION With a mean treatment group difference of 1 cm in 12-month growth response, although statistically significant, the IAD group was considered non-inferior compared with the FHD group. Early growth prediction can be used to tailor the dose to the individual patient's needs, resulting in lower overall GH dose.

Abstract
OBJECTIVE To assess direct costs and describe resource utilisation associated with the first 6 months of insulin therapy in German patients with type 2 diabetes mellitus (DM). RESEARCH DESIGN AND METHODS This is an ongoing pan-European, non-interventional, prospective study observing the normal course of diabetes therapy of adult patients with type 2 DM in a diabetologic practice setting, and initiating insulin therapy in 2006. Diabetes therapy 6 months prior to initiation of insulin therapy was assessed retrospectively. For German patients (n = 256), direct costs associated with health-care resource utilisation prior to and after the insulin initiation were assessed and compared from the German statutory health insurance perspective. RESULTS The percentage of patients using blood glucose monitoring increased from 76.4 to 99.6%; 42.1% of patients remained on oral anti-diabetic medication, with metformin used most frequently (36.5%). Total average cost of resource use related to diabetes care per patient for the 6-month period prior to and 6 months after insulin initiation increased from Euro 579 to Euro 961. Mean total costs of diabetes care during 6 months after insulin initiation in the subgroup of obese patients with worse prognosis at baseline (HbA(1c)> or = 7.5% and BMI > or = 30 kg/m(2)) were Euro 1047 [95% CI 965; 1128] vs. Euro 903 [95% CI 840; 965] in other patients. CONCLUSIONS Resource utilisation and costs related to diabetes increased in the 6 months following insulin initiation, mainly driven by specialist care resource use, insulin, and blood glucose monitoring. Total direct costs of diabetes care of the patients with a less favourable profile of BMI and HbA(1c) at baseline are higher compared to other patients.

Abstract
A relationship between haemophilia and osteoporosis has been suggested, leading to the initiative for a larger study assessing this issue. Bone mineral density (BMD) was measured by osteodensitometry using dual energy X-ray absorptiometry (DEXA) in 62 male patients with severe haemophilia A; mean age 41 +/- 13.1 years, mean body mass index (BMI) 23.5 +/- 3.6 kg m(-2). Using the clinical score suggested by the World Federation of Hemophilia, all patients were assessed to determine the severity of their arthropathy. A reduced BMD defined as osteopenia and osteoporosis by World Health Organization criteria was detected in 27/62 (43.5%) and 16/62 (25.8%) patients, respectively. Fifty-five of sixty-two (88.7%) patients suffered from haemophilic arthropathy. An increased number of affected joints and/or an increased severity were associated with lower BMD in the neck of femur. Pronounced muscle atrophy and loss of joint movement were also associated with low BMD. Furthermore, hepatitis C, low BMI and age were found to be additional risk factors for reduced BMD in the haemophiliac. Our data shows that in haemophilic patients osteoporosis represents a frequent concomitant observation. The main cause for reduced bone mass in the haemophiliac is most probably the haemophilic arthropathy being typically associated with chronic pain and loss of joint function subsequently leading to inactivity. Further studies including control groups are necessary to elucidate the impact of comorbidities such as hepatitis C or HIV on the development of osteoporosis in the haemophiliac.
