To assess cardiovascular, glycaemic, weight and safety outcomes of long-term treatment with dulaglutide 1.5 mg compared with placebo in patients with a baseline HbA1c of less than 7% versus 7% or higher.Intention-to-treat analyses were performed on REWIND participants with a baseline HbA1c measurement, using Cox proportional hazards regression and mixed model for repeated measures. Subgroup analyses with factors for baseline HbA1c categories and their interaction with treatment group, as well as analyses within the HbA1c subgroups, were conducted. Additionally, sensitivity analyses were performed for baseline HbA1c subgroups of 6.5% or less and more than 6.5%.Of the 9876 eligible participants, 3921 and 5955 had a baseline HbA1c of less than 7% and 7% or higher, respectively. Mean baseline HbA1c was 6.3% and 8.0% and the mean duration of diabetes was 9.0 and 11.6 years in the respective subgroups. The less than 7% subgroup was slightly older and less frequently insulin-treated. There was no evidence of a differential dulaglutide treatment effect on body mass index (BMI) reduction, cardiovascular or safety outcomes of interest between the baseline HbA1c subgroups. Treatment-by-baseline HbA1c group interaction was significant for HbA1c change from baseline (P .001), with a greater reduction in the subgroup with higher baseline HbA1c values. Sensitivity analyses by baseline HbA1c subgroups of 6.5% or less and more than 6.5% showed similar results.The reduced incidence of cardiovascular events, and the reduction in BMI in participants treated with once-weekly dulaglutide, were independent of the baseline HbA1c level. Conversely, participants with a higher baseline HbA1c level had greater reductions in HbA1c. Dulaglutide has a positive benefit-risk profile and can be considered in patients with comparatively well-controlled HbA1c levels seeking optimal metabolic control and cardiovascular benefits.

This post hoc analysis investigated the effect of dulaglutide on cardiovascular disease (CVD) risk factors in subgroups of participants at increased CVD risk in the AWARD-11 study.Participants who received once weekly dulaglutide 1.5, 3.0 or 4.5 mg for 52 weeks were categorized according to their baseline Framingham CVD risk category [low (N = 295), medium (N = 481) and high (N = 1054) risk], as well as their baseline CVD risk according to the REWIND study eligibility criteria (N = 953). Serum lipids and vital signs were assessed at baseline and at 52 weeks. Data were analysed as least squares mean percentage change from baseline for lipids and least squares mean change from baseline for vital signs.Demographic and baseline clinical characteristics were balanced across doses within the CVD risk groups. In the high Framingham CVD risk and REWIND-like groups, dulaglutide resulted in dose-related decreases in total cholesterol (≤6.0%), non-high-density lipoprotein cholesterol (≤8.8%), very-low-density lipoprotein cholesterol (≤19.4%) and triglycerides (≤21.5%), with little change in low-density lipoprotein cholesterol and high-density lipoprotein cholesterol. Systolic and diastolic blood pressure decreased up to 5.6 mmHg and 1.6 mmHg, respectively, and heart rate increased up to 2 beats/min.This post hoc analysis suggests the magnitude of the favourable effects of dulaglutide 3.0 mg and 4.5 mg on several cardiometabolic CVD risk factors was similar to, if not greater than, those of dulaglutide 1.5 mg among participants with type 2 diabetes and increased CVD risk.gov Identifier: NCT03495102.

Background/Objectives: This article compares the effectiveness of baricitinib (BARI) 4 mg (oral, Janus kinase [JAK] 1/2 inhibitor) versus other targeted synthetic/biologic disease-modifying antirheumatic drugs, in combination with methotrexate (MTX), in moderate-to-severe rheumatoid arthritis patients with inadequate response (IR) to MTX. Methods: A systematic literature review was conducted to identify randomized controlled trials (RCTs) of the interventions of interest. Bayesian network meta-analyses (NMA) were used to compare American College of Rheumatology (ACR) responses at 24 weeks. A series of prespecified sensitivity analyses addressed the potential impact of, among others, baseline risk, treatment effect modifiers, and trial design on treatment response. Results: Nineteen RCTs were included in the NMA (primary analysis). For ACR20, BARI 4 mg + MTX was found to be more effective than adalimumab (ADA) 40 mg + MTX (Odds Ratio [OR] 1.33), abatacept (ABA) 10 mg + MTX (IV/4 weeks) (OR 1.45), infliximab (IFX) 3 mg + MTX (IV/8 wks) (OR 1.63), and rituximab (RTX) 1000 mg + MTX (OR 1.63). No differences were found on ACR50. For ACR70, BARI 4 mg + MTX was more effective than ADA 40 mg + MTX (OR 1.37), ABA 10 mg + MTX (OR 1.86), and RTX 1000 mg + MTX (OR 2.26). Sensitivity analysis including 10 additional RCTs with up to 20% of patients with prior biologic use showed BARI 4 mg + MTX to be more effective than tocilizumab (TCZ) 8 mg + MTX on ACR20 (OR 1.44). Results for all sensitivity analyses were consistent with the direction and magnitude of the primary results. Key limitations include the time span in which trials were conducted (1999–2017), during which patient characteristics and treatment approaches might have changed. Conclusion: This NMA suggests that BARI 4 mg + MTX is an efficacious treatment option in the MTX-IR population as evidenced by the robustness of results.

Background/Objective Baricitinib is a selective and reversible Janus kinase (JAK) inhibitor indicated for the treatment of adult patients with moderately to severely active rheumatoid arthritis (RA) who have had an inadequate response to one or more tumor necrosis factor inhibitors (TNFis) and has been shown to improve multiple clinical and patient-reported outcomes. However, it is unclear what the budgetary impact would be for US commercial payers to add baricitinib to their formulary and how the efficacy of baricitinib compares to other disease-modifying antirheumatic drugs (DMARDs) with a similar indication. Methods A budget impact model (BIM) was developed for a hypothetical population of 1 million plan members that compared a world without and with baricitinib. A retrospective observational study was carried out to estimate market utilization of advanced therapies. Number needed to treat (NNT) and cost per additional responder were calculated for American College of Rheumatology (ACR) 20%/50%/70% improvement criteria (ACR20/50/70) response outcomes combining cost estimates from the BIM and efficacy values from a network meta-analysis (NMA). The model included costs related to drug acquisition and monitoring costs. Results Adding baricitinib would save a commercial payer $US169,742 for second-line therapy and $US135,471 for third-line therapy over a 2-year time horizon (all costs correspond to 2019 US dollars). Cost savings were driven by baricitinib drawing market share away from more expensive comparators. The NMA, based on nine studies, found no statistically significant differences in the median treatment difference between baricitinib and comparators except for versus a conventional synthetic DMARD (csDMARD), and thus NNT versus a csDMARD was similar. The cost per additional responder for baricitinib in patients with inadequate response to a TNFi was substantially lower than all other treatments for all three ACR response criteria at 12 weeks (ACR20: $US129,672; ACR50: $US237,732; ACR70: $US475,464), and among the lowest at 24 weeks (ACR20: $US167,811; ACR50: $US259,344; ACR70: $US570,557). Conclusions Baricitinib, compared to other DMARDs, was a less expensive option (− $US0.01 incremental cost per member per month in second- and third-line therapy over a 2-year time horizon) with comparable efficacy in patients with inadequate response to TNFi. Adding baricitinib to formulary would likely be cost saving for US payers and expands treatment options for these patients.

Introduction: This exploratory post hoc analysis investigated the relative changes in glycated haemoglobin (HbA1c) in patients with type 2 diabetes mellitus (T2DM) treated with dulaglutide versus active comparators across a continuous range of baseline HbA1c values using data from three phase III randomised controlled trials. Methods: Data from patients receiving once-weekly dulaglutide 0.75 and 1.5 mg, once-daily sitagliptin 100 mg, once-daily liraglutide 1.8 mg or twice-daily exenatide 10 ?g in the intent-to-treat populations in the AWARD-5, AWARD-6 and AWARD-1 trials were analysed using last observation carried forward analysis of covariance. Starting with the predefined statistical model from each study, the type of association between HbA1c baseline and change at 26 weeks was modelled. Consistency of treatment effect was assessed via treatment-by-baseline HbA1c interaction terms. Results: Improvements in HbA1c occurred in all treatment groups across the entire baseline HbA1c range. The relationship between HbA1c baseline and magnitude of change was linear in all treatment groups, with greater reductions in patients with higher baseline HbA1c values. Across the continuum of baseline HbA1c values, patients treated with dulaglutide 1.5 mg achieved a similar mean HbA1c reduction to patients receiving liraglutide 1.8 mg and a greater reduction than patients receiving twice-daily exenatide or sitagliptin. In AWARD-5, the treatment-by-baseline HbA1c interaction P value (0.001) demonstrated progressively greater HbA1c reduction in dulaglutide-treated compared with sitagliptin-treated patients as baseline HbA1c increased. Conclusion: Our results suggest that dulaglutide is an appropriate therapeutic option for patients with T2DM across a wide range of baseline HbA1c values, including those with poor metabolic control.

Introduction In the last 20 years, biologic and targeted synthetic disease-modifying antirheumatic drugs (DMARDs) have become available for treating rheumatoid arthritis (RA), and a treat-to-target strategy has been introduced. We hypothesise that these advances should have resulted in changes to the characteristics of patients with RA participating in clinical trials of the newest therapies. This study determined whether the baseline characteristics of patients with RA enrolled in clinical trials have changed in the past decade versus patients participating in earlier RA studies. Methods This secondary analysis was based on randomised controlled trials (RCTs) identified in a systematic literature review. Baseline characteristics of patients with RA with inadequate response to conventional synthetic DMARDs were compared between RCTs published in 1999–2009 and those published in 2010–2017 using random-effects meta-analyses. Results Forty RCTs were analysed: 22 from 1999–2009 and 18 from 2010–2017. No significant difference between the two timeframes and no obvious trend over time were observed for age, gender, disease duration, rheumatoid factor status, tender and swollen joint counts, physician and patient global assessments of disease activity, and pain scores. Variability between RCTs was high. Similar results were observed for Disease Activity Scores and Health Assessment Questionnaire-Disability Index scores, but with low variability between RCTs. Conclusion The baseline characteristics of patients with RA participating in RCTs do not appear to have changed in the last decade despite the availability of new treatments and a different treatment approach. Further research should determine the impact of baseline patient characteristics on patients’ response to RA treatments. Electronic Supplementary Material The online version of this article (10.1007/s12325-020-01435-6) contains supplementary material, which is available to authorized users., Plain Language Summary In the last 20 years, new treatments and a new treatment approach (called treat-to-target) have been introduced for rheumatoid arthritis (RA). Consequently, the characteristics of patients with RA participating in clinical trials of the newest therapies should have changed compared with those of patients who participated in clinical trials of older therapies. This is important as patient characteristics may influence patients’ response to drug treatment. To determine whether characteristics of patients with RA have changed over time, we compared the baseline characteristics (e.g. age, gender, disease duration, measures of disease activity, and pain scores) of patients with RA between 22 clinical trials published in 1999–2009 and 18 published in 2010–2017. No significant difference between the two timeframes and no obvious trend over time were observed for any baseline characteristic of patients with RA, including physician and patient measures of disease activity, and patient measures of physical function and pain. Thus, the baseline characteristics of patients with RA participating in clinical trials do not appear to have changed in the last decade despite the introduction of new treatments and the treat-to-target approach. Further research is needed to determine the impact of baseline patient characteristics on patients’ response to RA treatments.

ObjectiveTo compare improvement in pain and physical function for patients treated with baricitinib, adalimumab, tocilizumab and tofacitinib monotherapy from randomised, methotrexate (MTX)-controlled trials in conventional synthetic disease-modifying antirheumatic drugs (csDMARDs)/biologic (bDMARD)-naïve RA patients using matching-adjusted indirect comparisons (MAICs).MethodsData were from Phase III trials on patients receiving monotherapy baricitinib, tocilizumab, adalimumab, tofacitinib or MTX. Pain was assessed using a visual analogue scale (0–100 mm) and physical function using the Health Assessment Questionnaire-Disability Index (HAQ-DI). An MAIC based on treatment-arm matching, an MAIC with study-level matching and Bucher’s method without matching compared change in outcomes between therapies. Matching variables included age, gender, baseline disease activity and baseline value of outcome measure.ResultsWith all methods, greater improvements were observed in pain and HAQ-DI at 6 months for baricitinib compared with adalimumab and tocilizumab (pConclusionsResults suggest greater pain reduction and improved physical function for baricitinib monotherapy compared with tocilizumab and adalimumab monotherapy. No statistically significant differences in pain reduction and improved physical function were observed between baricitinib and tofacitinib with the MAIC analyses.

Objectives: The approval in more than 50 countries of baricitinib, an oral Janus Kinase inhibitor for the treatment of Rheumatoid Arthritis (RA), warrants a framework for corresponding economic evaluations. To develop a comprehensive economic model assessing the cost-effectiveness of baricitinib for the treatment of moderately-to-severely active RA patients in comparison to other relevant treatments, considering the natural history of the disease, real world treatment patterns, and clinical evidence from the baricitinib trials. Methods: A systematic literature review of previously developed models in RA was conducted to inform the model structure, key modeling assumptions and data inputs. Consultations with rheumatologists were undertaken to validate the modeling approach and underlying assumptions. Results: A discrete event simulation model was developed to international best practices with flexibility to assess the cost-effectiveness of baricitinib over a lifetime in a variety of markets. The model incorporates treatment sequencing to adequately reflect treatment pathways in clinical practice. Outcomes assessed include cost and quality-adjusted life years, allowing for a full incremental analysis of cost-effectiveness of competing treatments and treatment sequences. Conclusion: The economic model developed provides a robust framework for future analyses assessing the cost-effectiveness of baricitinib for the treatment of RA in specific country settings.

Aim We evaluated the safety of baricitinib in an East Asian (EA) patient population with moderate-to-severely active rheumatoid arthritis (RA), through an integrated sub-analysis of data from the overall baricitinib RA clinical program. Methods Data from EA patients who received any dose of baricitinib from five completed studies (1 Phase 2, 4 Phase 3) and an ongoing long-term extension study were pooled up to 1 September, 2016. Exposure-adjusted incidence rates (EAIR) and incidence rates (IRs), both per 100 patient-years (PY), were calculated. Results This analysis included 740 EA patients with 1294 PY of total baricitinib exposure (maximum 3.5 years). Overall, 109 patients discontinued baricitinib due to adverse events (AEs); EAIR: 8.4. No deaths were reported in this cohort. Serious AEs were reported by 125 patients (EAIR: 9.7). Serious infections were the most common serious AEs (n = 53, IR: 4.15). IR of herpes zoster infection was 6.2; the majority of events were of mild-to-moderate severity. Three cases (IR: 0.23) of tuberculosis were reported. The IRs of malignancy (excluding non-melanoma skin cancer) was 0.99 and EAIR specifically of lymphoma was 0.1. The IR of major adverse cardiovascular events was 0.26, and deep vein thrombosis was reported in four patients (EAIR: 0.3). Two cases of gastrointestinal perforations (EAIR: 0.2) were reported. Conclusion Integrated data show that baricitinib is well-tolerated in EA patients with moderate-to-severely active RA in the context of demonstrated efficacy, which is generally consistent with safety results of the overall study population.

Methods Data from patients receiving once-weekly dulaglutide 0.75 and 1.5 mg, once-daily sitagliptin 100 mg, once-daily liraglutide 1.8 mg or twice-daily exenatide 10 μg in the intent-to-treat populations in the AWARD-5, AWARD-6 and AWARD-1 trials were analysed using last observation carried forward analysis of covariance. Starting with the predefined statistical model from each study, the type of association between HbA1c baseline and change at 26 weeks was modelled.

The relationship between HbA1c baseline and magnitude of change was linear in all treatment groups, with greater reductions in patients with higher baseline HbA1c values. Across the continuum of baseline HbA1c values, patients treated with dulaglutide 1.5 mg achieved a similar mean HbA1c reduction to patients receiving liraglutide 1.8 mg and a greater reduction than patients receiving twice-daily exenatide or sitagliptin.

Conclusion Our results suggest that dulaglutide is an appropriate therapeutic option for patients with T2DM across a wide range of baseline HbA1c values, including those with poor metabolic control.

AIMS Insulin-treated patients with type 2 diabetes (T2D) and obesity are challenged in achieving body weight stability or reduction, in addition to glycaemic control. Post-hoc analyses of body weight and insulin dose data from the AWARD-4 trial involved comparison of treatment with once-weekly dulaglutide 1.5 mg (N = 295) or 0.75 mg (N = 293) and treatment with daily insulin glargine (N = 296), each with prandial insulin lispro (± metformin). MATERIALS AND METHODS Changes in weight and in the proportion of patients without weight gain or with weight loss of at least 3%, 5% or 10% or composites of HbA1c less than 7% without weight gain and weight loss of at least 3% after 52 weeks were compared between the dulaglutide (either dose) groups and the insulin glargine group, overall and by baseline BMI (

Background: In Phase 3 trial, RA-BEGIN, baricitinib (BARI) monotherapy demonstrated superiority to MTX in pain reduction and HAQ-DI improvement in treatment of csDMARD-naive active RA patients.1 No prospective head-to-head (H2H) trial data are available comparing BARI monotherapy vs. bDMARD monotherapy in csDMARD-naive RA patients. Objectives: To assess pain and HAQ-DI for BARI monotherapy from a randomized, MTX-controlled trial vs adalimumab (ADA), tocilizumab (TCZ), and tofacitinib (TOFA) monotherapy from similar randomized, MTX-controlled trials in csDMARD/bDMARD naive RA patients using matching-adjusted indirect comparison (MAIC). Methods: Individual patient data from the RA-BEGIN BARI 4 mg arm were weighted to match baseline characteristics of the ADA arm from PREMIER,2 TOFA 5 mg arm from ORAL-START,3 and TCZ 8 mg/kg arm from combination of AMBITION and FUNCTION,4,5 respectively; MTX arms were also matched between trials. Method of moments was used to determine weights for age, gender, baseline disease scores, and baseline values of the outcome variable. Mean change on pain VAS and HAQ-DI at Week 24 for BARI were adjusted for the above baseline characteristics with the weighted linear model, and then indirectly compared vs. respective published results for Week 24 TCZ and TOFA and for Week 26 ADA data. Statistical significance of the weighted treatment effect was assessed with the bootstrap method. Sensitivity analyses included MAIC with study level matching6, Bucher’s method without matching adjustment7, and inclusion of disease duration as an additional matching variable. Results: Across trials, the mean baseline pain VAS ranged from 58.7 to 65.2 with a 6-month mean change in pain of -28.3 to -33.5 for the MTX arm, indicating comparability between trials. Similar HAQ-DI and changes in HAQ-DI for the MTX arm were observed. At Week 24, BARI showed numerically greater improvement over MTX in pain than that for TCZ, ADA, and TOFA; statistically significant pain improvement were observed for BARI vs ADA and TCZ with all 3 matching methods but only with the Bucher method for TOFA (figure 1). BARI-treated patients showed significantly greater improvement in HAQ-DI at Week 24 than TCZ and ADA but not TOFA (figure 1). Sensitivity analyses showed consistent results. Conclusions: This indirect comparison of different studies in cs/bDMARD-naive RA patients, after adjusting for differences in baseline characteristics, suggest a greater pain reduction and improved physical function for BARI monotherapy vs. TCZ and ADA monotherapy. There is suggestion of greater pain reduction for BARI monotherapy vs. TOFA monotherapy, but no differences in improved physical function between the JAK inhibitors. A H2H clinical trial would be needed to confirm these results. References 1Fleischmann, et al. Arthritis Rheumatol2017. 2Breedveld, et al. Arthritis Rheumatol2006. 3Lee, et al.

BACKGROUND We investigated the rate of severe hypoglycemic events and confounding factors in patients with type-2-diabetes treated with sulfonylurea (SU) at specialized diabetes centers, documented in the German/Austrian DPV-Wiss-database. METHODS Data from 29,485 SU-treated patients were analyzed (median[IQR] age 70.8[62.2-77.8]yrs, diabetes-duration 8.2[4.3-12.8]yrs). The primary objective was to estimate the event-rate of severe hypoglycemia (requiring external help, causing unconsciousness/coma/convulsion and/or emergency.hospitalization). Secondary objectives included exploration of confounding risk-factors through group-comparison and Poisson-regression. RESULTS Severe hypoglycemic events were reported in 826(2.8%) of all patients during their most recent year of SU-treatment. Of these, n = 531(1.8%) had coma, n = 501(1.7%) were hospitalized at least once. The adjusted event-rate of severe hypoglycemia [95%CI] was 3.9[3.7-4.2] events/100 patient-years (coma: 1.9[1.8-2.1]; hospitalization: 1.6[1.5-1.8]). Adjusted event-rates by diabetes-treatment were 6.7 (SU + insulin), 4.9 (SU + insulin + other OAD), 3.1 (SU + other OAD), and 3.8 (SU only). Patients with ≥1 severe event were older (p 60 mL/min: 3.9). CONCLUSIONS These real-life data showed a rate of severe hypoglycemia of 3.9/100 patient-years in SU-treated patients from specialized diabetes centers. Higher risk was associated with known risk-factors including lack of diabetes-education, older age, and decreased eGFR, but also with lower BMI and lower triglyceride-levels, suggesting that SU-treatment in those patients should be considered with caution.

The cost per additional responder for baricitinib in patients with inadequate response to a TNFi was substantially lower than all other treatments for all three ACR response criteria at 12 weeks (ACR20: $US129,672; ACR50: $US237,732; ACR70: $US475,464), and among the lowest at 24 weeks (ACR20: $US167,811; ACR50: $US259,344; ACR70: $US570,557).Baricitinib, compared to other DMARDs, was a less expensive option (- $US0.01 incremental cost per member per month in second- and third-line therapy over a 2-year time horizon) with comparable efficacy in patients with inadequate response to TNFi. Adding baricitinib to formulary would likely be cost saving for US payers and expands treatment options for these patients.

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).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.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.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.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.

Background and objective The INSTIGATE study assessed healthcare costs and clinical outcomes in patients with type 2 diabetes mellitus starting insulin therapy in Spain over a 24-month follow up period. Material and methods This was an observational, non-interventional, prospective, multicenter study. Costs incurred in the previous 6 months were assessed at each visit. Results A total of 172 patients with a mean body mass index of 29.6 kg/m 2 , a mean [standard deviation] duration of diabetes of 10.9 [7.0] years and a hemoglobin A 1c value of 9.2% [1.5%] were followed up for at least 12 and up to 24 months. Direct costs were assessed from the perspective of the Spanish healthcare system. Long/intermediate-acting insulin alone was started in 116 patients (67.4%). After 6, 12, and 24 months of insulin treatment, mean [SD] intraindividual changes from baseline in hemoglobin A 1c were −1.9% [1.65%], −1.6 [1.73%], and −1.5% [1.76%] respectively. Mean (median) total diabetes-related healthcare costs per patient increased from €659 (€527) to €1.085 (€694) 6 months after insulin initiation, decreased to €646 (€531) after 12 months, and increased again after 24 months to €667 (€539). Insulin/oral antidiabetics, primary/specialized care, and blood glucose monitoring accounted for 41%, 26%, and 19% of total cost at 24 months respectively. Conclusions Clinical parameters of these patients with type 2 diabetes mellitus improved following insulin initiation. After a temporary increase, direct healthcare costs of diabetes care returned to baseline values at the end of the follow-up period.

Resumen Antecedentes y objetivo El estudio INSTIGATE evalua los costes directos sanitarios y los resultados clinicos en pacientes con diabetes mellitus tipo 2 que inician insulinoterapia en Espana, durante 24 meses. Material y metodo Estudio observacional, no intervencionista, prospectivo y multicentrico. En cada visita se evaluaron los costes incurridos durante los 6 meses previos. Resultados En total se evaluaron 172 pacientes durante al menos 12 o un maximo de 24 meses con un indice de masa corporal medio de 29,6 kg/m 2 , una duracion media [desviacion estandar] de la enfermedad de 10,9 [7,0] anos y un porcentaje de hemoglobina A 1c de 9,2% [1,5%]. Un total de 116 pacientes (67,4%) iniciaron insulina de accion prolongada/intermedia solamente. Los cambios medios intraindividuales en los valores iniciales de hemoglobina A 1c tras 6, 12 y 24 meses de la insulinoterapia fueron, respectivamente, -1,9 [1,65%], -1,6 [1,73%] y -1,5% [1,76%]. La media (mediana) del total de los costes directos sanitarios por paciente aumento de 659 € (527 €) a 1.085 € (694 €) 6 meses despues del inicio de la insulinoterapia, bajo a 646 € (531 €) despues de 12 meses, y 24 meses despues aumento nuevamente a 667 € (539 €). A los 24 meses, los costes de insulina/antidiabeticos orales, medicina general/especializada, y monitorizacion de la glucemia representaron el 41, 26 y 19%, respectivamente, de los costes totales. Conclusiones Los parametros clinicos de estos pacientes con diabetes mellitus tipo 2 mejoraron tras iniciar la insulinoterapia. Tras un incremento temporal, los costes directos sanitarios del tratamiento de la diabetes volvieron a los valores basales al final del periodo de seguimiento.

To determine if EuroQoL 5-Dimension Health Questionnaire (EQ-5D) health utility scores were able to discriminate among different levels of improvement in psoriasis severity following therapy.Data were from three placebo-controlled phase 3 ixekizumab studies (UNCOVER-1, UNCOVER-2, and UNCOVER-3) with patients who had baseline Dermatology Life Quality Index scores10 (DLQI10). Psoriasis severity (Psoriasis Area and Severity Index [PASI]), general health utility (EQ-5D), and psoriasis-specific utility (EQ-PSO, UNCOVER-3 only) were assessed. EQ-5D-5L utility scores were generated using the England EQ-5D-5L value set, a crosswalk applied to the EQ-5D-3L United States (US) and United Kingdom (UK) value sets, and a regression-based exploratory scoring function for the EQ-PSO (UK). Analysis of variance was used to estimate change in EQ-5D-5L from baseline to Week 12 per PASI improvement level: PASI50, PASI 50 to75, PASI 75 to90, PASI 90 to100, and PASI 100. Missing data were imputed using the last observation carried forward method. Value sets for the UK, England, and the US were applied.In total, 2085 patients across UNCOVER-1, UNCOVER-2, and UNCOVER-3 had baseline DLQI10 and available utility scores. At Week 12, mean EQ-5D utility scores increased with increasing PASI improvement levels (p 0.001, all analyses). Mean health utilities for PASI 90 to100 and PASI 100 were similar when based on the generic classifier, whereas a clear differentiation between PASI 90 to100 and PASI 100 was observed for EQ-PSO mean scores (UNCOVER-3 only, n = 645; PASI 90 to100: 0.141, PASI 100: 0.200; adjusted p = 0.043).EQ-5D-5L index-based scores have limited ability to differentiate among psoriasis patients at the highest PASI improvement levels. ConclusionsL Adding psoriasis-specific EQ-PSO dimensions to the EQ-5D may enhance responsiveness to improvement in skin clarity at the highest PASI levels, and, therefore, generate utility scores that better reflect treatment benefit in cost-utility models.

Background: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. Abstract: Objective: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. Abstract: Methods: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). Abstract: Results:Results: We studied 738 patients with a mean (SD) age of 66 (11) years and BMI of 30.6 (5.2) kg/m. 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) &lsqb;one-slope model&rsqb;. 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). Abstract: Conclusion: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.

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 (

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.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.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 of7% 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%.Differences in insulin regimen were observed between countries, and appeared to reflect the guidelines and treatment regimens used.

This study aimed to assess the relative contributions of postprandial and fasting glucose concentrations to overall hyperglycaemia.Patients with type 2 diabetes (n=973) carried out self-monitored blood glucose (SMBG) profiles on entry into the European Exenatide (EUREXA) trial. Glucose area under the curve was calculated for postprandial excursions (AUC(ppg)) and total daytime concentrations6.1 mmol/L (AUC(total)), as well as for the percentage of glycaemia due to postprandial excursions (%(ppg)). In addition, OGTT scores were assessed for each patient. Results were evaluated according to defined HbA(1c) categories.There was a significant linear relationship between HbA(1c) and the derived variables of AUC(ppg), AUC(total) and %(ppg) (P0.001 for each), with explained variance greatest for AUC(total) (r(2)=37.4%). AUC(ppg) increased only slightly up to an HbA(1c) of 7.0%, but showed a steeper increase in higher HbA(1c) categories. Also, the increase in AUC(total) with increasing HbA(1c) was much more pronounced. As a result, the postprandial glucose excursion as a proportion of total glucose (%(ppg)) decreased across HbA(1c) categories from 61.0% at HbA(1c)6.5% to 22.0% at HbA(1c)≥9.0%. HOMA-IR remained virtually unchanged through all HbA(1c) categories, while HOMA-B showed no large changes up to HbA(1c) 7.0%, but then decreased at higher HbA(1c) values. The ΔI30/ΔG30 ratio decreased in the HbA(1c) 7.0-7.9% category, but did not change greatly at higher HbA(1c) categories.With increasing HbA(1c), there was a decrease in the contribution of postprandial hyperglycaemia to total glycaemia, and fasting hyperglycaemia became more important. This is consistent with impaired insulin release, particularly first-phase release, at higher HbA(1c) levels.

The term osseoperception describes the capability of developing a subtle tactile sensibility over dental implants. The present clinical study aims at clarifying the question of how far tactile sensibility is to be attributed to the periodontium of the natural opposing tooth of the implant.

ObjectiveInitial 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.DesignThis was a randomized, open-label, multi-center study.MethodsThe 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 ResultsIn 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 ConclusionWith 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.

We investigated the rate of severe hypoglycemic events and confounding factors in patients with type 2 diabetes treated with sulfonylurea at specialized diabetes centers, documented in the German/Austrian DPV-Wiss database.Data from 29 485 sulfonylurea-treated patients were analyzed (median[IQR] age 70.8[62.2-77.8] years, diabetes duration 8.2[4.3-12.8] years). The primary objective was to estimate the event rate of severe hypoglycemia (requiring external help, causing unconsciousness/coma/convulsion and/or emergency hospitalization). Secondary objectives included exploration of confounding risk factors through group comparison and Poisson regression.Severe hypoglycemic events were reported in 826(2.8%) of all patients during their most recent year of sulfonylurea treatment. Of these, n = 531(1.8%) had coma, n = 501(1.7%) were hospitalized at least once. The adjusted event rate of severe hypoglycemia [95%CI] was 3.9[3.7-4.2] events/100 patient-years (coma: 1.9[1.8-2.1]; hospitalization: 1.6[1.5-1.8]). Adjusted event rates by diabetes treatment were 6.7 (sulfonylurea + insulin), 4.9 (sulfonylurea + insulin + other OAD), 3.1 (sulfonylurea + other OAD) and 3.8 (sulfonylurea only). Patients with ≥1 severe event were older (p 0.001) and had longer diabetes duration (p = 0.020) than patients without severe events. Participation in educational diabetes-programs and indirect measures of insulin-resistance (increased BMI, plasma-triglycerides) were associated with fewer events (all p 0.001). Impaired renal function was common (n = 3113 eGFR; ≤30 mL/min) and associated with an increased rate of severe events (≤30 mL/min: 7.7; 30-60 mL/min: 4.8;60 mL/min: 3.9).These real-life data showed a rate of severe hypoglycemia of 3.9/100 patient-years in sulfonylurea-treated patients from specialized diabetes centers. Higher risk was associated with known risk factors including lack of diabetes education, older age and decreased eGFR but also with lower BMI and lower triglyceride levels, suggesting that sulfonylurea treatment in those patients should be considered with caution.

Bleeding in the calf or ankle joint may lead to ankle equinus deformity, particularly in childhood and during adolescence. We assessed the long-term functional and radiographic results after Achilles tendon lengthening for ankle equinus deformity in hemophiliacs.Between 1975 and 1986, 30 hemophilic patients with pes equinus were surgically managed by Achilles tendon lengthening. Of these, 23 were followed up prospectively twice a year for an average of 13 (1-24) years. The mean age at operation was 29 (12-46) years. The clinical results were documented according to the score of the Advisory Committee of the World Federation of Hemophilia (WFH), while radio-graphs were evaluated using the Pettersson score. On average, preoperative ankle equinus deformity was 21 (5-55) degrees. Mean range of motion was 21 (5-42) degrees prior to surgery.At the first postoperative examination 1 year after surgery, 21/23 cases were improved, and 9/21 reached dorsiflexion to at least neutral position. At the last follow-up, ankle equinus deformity was 10 (4-20) degrees on average. 20/23 patients still showed significant improvement compared to their condition before surgery. 7 patients still had complete correction of the equinus deformity, while mean range of motion decreased constantly over the observation period. The clinical score was significantly improved 1 year after surgery and diminished only slightly afterwards. Radio-graphic outcome deteriorated, with scores rising from 4.3 (1-10) points preoperatively to 7.3 (3-12) points at last follow-up.Most patients treated for hemophilic pes equinus by Achilles tendon lengthening experienced long-term benefit concerning the equinus deformity, but gradually lost overall movement of the ankle joint. Progression of the ankle arthropathy cannot be hindered.

In this study the long-term value of corrective osteotomy around the knee was evaluated by means of clinical and radiographic parameters. Between 1974 and 1984 we performed 52 corrective osteotomies in the vicinity of the knee on patients affected by haemophilic arthropathy. Forty-two patients (45 osteotomies) were adequately followed-up at an average 11.6 years postoperatively. Using the clinical score of the Advisory Committee of the World Federation of Haemophilia, 38 patients showed a postoperative improvement, five remained clinically unchanged and two showed deterioration. Range of motion of the knee joint did not significantly improve postoperatively. The radiographic Pettersson score showed only a marginal decrease by an average 0.003 points at the time of follow-up. Only one patient needed subsequent joint replacement of both knees, on the left side 13 years after osteotomy and on the right side 8 years after osteotomy. Even in cases of marked radiographic joint destruction, corrective osteotomy shows acceptable long-term clinical results, underlining the feasibility of this management option in the treatment of haemophilic arthropathy of the knee. Although moderate cartilage degenerations in the femoropatellar complex and in the contralateral compartment can be tolerated, this therapy should primarily be contemplated for those patients where damage is unicompartmental and a corresponding axial deviation is found. Particularly the younger patient can benefit from this treatment option in that joint replacement may possibly wholly be avoided or at least postponed to a later stage of life.

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.Keywords: type 2 diabetes mellitus, costs, resource use, insulin

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 A1c (HbA1c) 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) HbA1c 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]%). HbA1c 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 HbA1c 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.

The purpose of this clinical trial was to determine the active tactile sensibility of natural teeth and to obtain a statistical analysis method fitting a psychometric function through the observed data points. On 68 complete dentulous test persons (34 males, 34 females, mean age 45.9 ± 16.1 years), one pair of healthy natural teeth each was tested: n = 24 anterior teeth and n = 44 posterior teeth. The computer-assisted, randomized measurement was done by having the subjects bite on thin copper foils of different thickness (5-200 µm) inserted between the teeth. The threshold of active tactile sensibility was defined by the 50% value of correct answers. Additionally, the gradient of the sensibility curve and the support area (90-10% value) as a description of the shape of the sensibility curve were calculated. For modeling the sensibility curve, symmetric and asymmetric functions were used. The mean sensibility threshold was 14.2 ± 12.1 µm. The older the subject, the higher the tactile threshold (r = 0.42, p = 0.0006). The support area was 41.8 ± 43.3 µm. The higher the 50% threshold, the smaller the gradient of the curve and the larger the support area. The curves showing the active tactile sensibility of natural teeth demonstrate a tendency towards asymmetry, so that the active tactile sensibility of natural teeth can mathematically best be described by using the asymmetric Weibull function.

The term osseoperception describes the capability of developing a subtle tactile sensibility over dental implants. The present clinical study aims at clarifying the question of how far tactile sensibility is to be attributed to the periodontium of the natural opposing tooth of the implant.Thirty-two subjects with single-tooth implants with natural opposing teeth were included in this clinical, single-blind, split-mouth study. The natural antagonistic tooth of the implant and the corresponding natural contralateral tooth were anesthetized with a locally infiltrated articaine anesthetic. In a computer-assisted and randomized way, copper foils of varying thickness (0-100 µm) were placed interocclusally between the single-tooth implant and the natural opposing tooth, and between the contralateral pair of natural opposing teeth in order to investigate the active tactile sensibility according to the psychophysical method of constant stimuli and evaluate it statistically by the Weibull distribution.The average tactile sensibility of the implants with anesthetized antagonists at the 50% value calculated by means of the Weibull distribution was 20 ± 11 µm with a support area (90%-10% value) of 77 ± 89 µm. For the pair of natural teeth, the tactile sensibility at the 50% value was 16 ± 9 µm with a support area of 48.4 ± 93 µm. This resulted in an average intraindividual difference of 3.5 ± 7 µm at the 50% value and 29 ± 93 µm in the support area. The statistical calculations demonstrated an equivalent tactile sensibility (50% value) of the single-tooth implant and the contralateral natural control tooth with the natural antagonists being anesthetized in each case (double t-test, equivalence limit ± 8 µm, P0.01, power80%).Apparently, the active tactile sensibility of single-tooth implants with natural opposing teeth is not only to be attributed to the periodontium of the opposing tooth but also to a perception over the implant itself. This could support the hypothesis according to which the implant may have a tactile sensibility of its own.

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.

To describe the characteristics at baseline of patients with type 2 diabetes mellitus who are initiating insulin.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.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.Insulin treatment was only initiated after HbA1(c) values were considerably higher than recommended in treatment guidelines for a sustained period of time.

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).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.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 BMIor = 30 kg/m(2)) were Euro 1047 [95% CI 965; 1128] vs. Euro 903 [95% CI 840; 965] in other patients.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.

To quantify wear processes by measuring the retention force changes and the fitting tolerance at different prefabricated attachment systems to estimate the wear constancy and applicability in clinical practice.Seven prefabricated attachment systems (Dalbo-Classic, Dalbo-PLUS, Dalbo-Z, Mini-Gerber-PLUS, Stufenexzenter, SpharoLock, and Degussa-Kugelankersystem) with different construction and alloy composition were tested. Twenty samples of each system were subjected to 10,000 insertion-separation cycles in a wear simulator with a periodontium-simulating specimen holder. The simulator was designed to record the force needed to insert and to separate the attachment and the distance moved during the insertion and separation cycles.All types of anchors showed wear that led to a loss or to an increase in retention force at the beginning of the wear simulation. Anchors with a plastic retention insert showed the slightest changes in retention force. The wear does not have an effect on the fitting tolerance.Anchor systems that possess an adjustable matrix should be preferred. They allow decreasing or increasing the retention force of an anchor if this force is changed by wear. There is no risk of a loss of support if forces in occlusal direction are exerted because there is no clinically relevant change in the fitting tolerance.

AIM: The purpose of this randomized split-mouth clinical trial was to determine the active tactile sensibility between single-tooth implants and opposing natural teeth and to compare it with the tactile sensibility of pairs of natural teeth on the contralateral side in the same mouth (intraindividual comparison). MATERIAL AND METHODS: The hypothesis was that the active tactile sensibilities of the implant side and control side are equivalent. Sixty two subjects (n=36 from Bonn, n=26 from Bern) with single-tooth implants (22 anterior and 40 posterior dental implants) were asked to bite on narrow copper foil strips varying in thickness (5-200 microm) and to decide whether or not they were able to identify a foreign body between their teeth. Active tactile sensibility was defined as the 50% threshold of correct answers estimated by means of the Weibull distribution. RESULTS: The results obtained for the interocclusal perception sensibility differed between subjects far more than they differed between natural teeth and implants in the same individual [implant/natural tooth: 16.7+/-11.3 microm (0.6-53.1 microm); natural tooth/natural tooth: 14.3+/-10.6 microm (0.5-68.2 microm)]. The intraindividual differences only amounted to a mean value of 2.4+/-9.4 microm (-15.1 to 27.5 microm). The result of our statistical calculations showed that the active tactile sensibility of single-tooth implants, both in the anterior and posterior region of the mouth, in combination with a natural opposing tooth is similar to that of pairs of opposing natural teeth (double t-test, equivalence margin: +/-8 microm, P 80%). Hence, the implants could be integrated in the stomatognathic control circuit.

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.
