RESUMEN

BACKGROUND: Different countries have their own systems for evaluating new medicines, and they make decisions as to when and how each new medicine is adopted. PURPOSE: To compare the rate of uptake of new diabetes medicines (dipeptidyl peptidase-4 inhibitors [DPP-4Is], glucagon-like peptide-1 receptor agonists [GLP1-RAs], and sodium-glucose co-transporter-2 inhibitors [SGLT2Is]) in the five most populated European countries. METHODS: The monthly volume of sales of antidiabetic drugs was extracted for each country from the IQVIA™ MIDAS® database for the period 2007 to 2016 and the defined daily doses (DDDs) were calculated. For each new drug, market shares were expressed as a percentage of the total market of non-insulin antidiabetic agents. RESULTS: Sharp differences were observed between the countries. Overall, the highest and fastest rates of uptake were seen for Germany and Spain, compared to lower rates for the UK and Italy. This was especially marked for DPP-4Is, where the market share reached over 30% of non-insulin antidiabetic drugs in Germany and Spain, compared to around 10% in the UK and Italy. In France, there was an initial rapid uptake, which stabilized at around 20% after three years. Rates of uptake were lower for the other drugs, with the GLP1-RAs reaching a market share of 2.5-4.5% in Germany, Spain and France, compared to less than 2.5% in the UK and Italy. The SGLT2Is reached a market share of 5-8% in Spain and Germany, compared to less than 4% in the UK and Italy, and they were not launched at all in France in March 2020. CONCLUSION: The differences in the uptake of new antidiabetic drugs may reflect different methods for assessing and introducing new medicines, as well as cultural factors. The uptake of the new medicines would appear to be more cautious in the UK and Italy, perhaps due to concerns about cost-effectiveness, whereas in Germany and Spain, and possibly also France, a new medicine's potential benefits may be prioritized.

RESUMEN

INTRODUCTION: Regular physical activity (PA) is recommended by all type 2 diabetes mellitus (T2DM) management guidelines. The OPADIA study aimed to determine whether using a specific patient questionnaire (Optima-PA©) could help T2DM patients increase their PA by leading to better physician-patient communication and improved levels of shared decision making concerning Specific, Measurable, Acceptable, Realistic, Timely (SMART)-PA micro-objectives. METHODS: Physicians participating in this multicentre, prospective, randomised, real-life study were allocated to a standard group (T2DM patients managed according to usual clinical practice, n = 24) or the OPTIMA-PA group (additional use of the questionnaire, n = 30). The main outcome was the percentage of inclusion visits ending with the setting up of at least one SMART-PA micro-objective. Other outcomes were the impact of the OPTIMA-PA questionnaire on patient perceptions of shared decision making (ENTRED questionnaire) and the impact of the OPTIMA-PA questionnaire and establishing SMART-PA micro-objectives as well as patient-perceived physician empathy (ENTRED questionnaire) and GP aptitude for patient-centredness (SEPCQ scores) on patient PA levels over a 3-month period (IPAQ-SF scores). RESULTS: One hundred twenty-two patients were included in the standard group and 134 in the OPTIMA-PA group. Unexpectedly, more inclusion visits ended with SMART-PA micro-objectives being set up in the standard group (p < 0.001): 81.1% (n = 99/122) versus 59.7% (n = 80/134). However, fewer patients in the OPTIMA-PA group felt that GPs made decisions alone (32% versus 60%; p < 0.0001). Positive correlations were also observed between GP patient-centredness and patient-perceived GP empathy or increased patient PA over the study period. CONCLUSION: Although the OPTIMA-PA questionnaire did not directly promote setting up of SMART-PA micro-objectives in T2DM patients, the OPADIA study demonstrated that this tool was effective at improving patient-physician relationships by increasing patient involvement in therapeutic decision making. Our study also highlighted the importance of GP aptitude for patient-centredness for improving PA in T2DM patients.

RESUMEN

INTRODUCTION: Diabetes is a growing epidemic that imposes a substantial economic burden on healthcare systems. This study aimed to evaluate the cost of managing type 2 diabetes (T2D) with dipeptidyl peptidase 4 inhibitors (DPP4Is) using real-world data. METHOD: This longitudinal study used data from the French EGB (Echantillon Généraliste des Bénéficiaires) database. The annual average direct healthcare cost of treating patients with T2D was calculated 3 years prior and 3 years after initiation of DPP4I therapy. Actual total ambulatory and hospital care expenditure for the 3 years after DPP4I initiation was compared to projected costs. The distribution of costs across all care modalities was assessed over the 6-year period. RESULTS: Ambulatory and hospital care expenditure data for 919 patients with T2D starting DPP4I therapy alone or in combination in 2013 were analyzed. A total of 526 patients (57.2%) were still being treated with DPP4I 3 years after DPP4I initiation. Regardless of the treatment regimen, the ambulatory and hospital care costs increased above projected costs in the first year following DPP4I initiation, and then declined during the second and third years to levels in line with or below projected values for patients using DPP4Is as an add-on therapy. The increase in total expenditure in the first year following DPP4I initiation and the subsequent decline in costs in the second and third years were both associated with general trends in consumption across all aspects of patient care. CONCLUSION: Despite an initial increase in healthcare expenditure, concomitant with reevaluation of patient care, this study showed that initiation of DPP4Is as an add-on therapy in French patients with T2D was associated with care expenditure that was in line or below predicted values within the 3 years following treatment initiation. Additional studies are required to evaluate the economic impact of the long-term treatment benefits.

RESUMEN

INTRODUCTION: Low-quality communication between patients and care providers and limited patient knowledge of the disease and the therapy are important factors associated with poor glycemic control in patients with type 2 diabetes. We conducted a multicenter study to determine whether structured and tailored information delivered by pharmacists to type 2 diabetic patients could improve patient treatment adherence, hemoglobin A1c (HbA1c) levels and knowledge about diabetes. METHODS: One hundred seventy-four pharmacies were randomized to deliver an educational program on diet, drug treatment, disease and complications during three 30-min interviews over a 6-month period, or to provide no intervention, to type 2 diabetic patients treated with oral antidiabetic agents. Medication adherence was assessed by measuring the medication possession ratio and diabetes control by collecting HbA1c values. Levels of patient treatment self-management and disease knowledge were assessed using self-questionnaires. RESULTS: Three hundred seventy-seven patients were analyzed. The medication possession ratio, already very high at baseline in the intervention (94.8%) and control (92.3%) groups, did not vary significantly after 6 months with no difference between the two groups. Significant decreases in HbA1c were observed in both groups at 6 months (p < 0.001) and 12 months (p < 0.01), with significantly greater changes from baseline in the intervention group than in the control group at 6 months (- 0.5% vs. - 0.2%, p = 0.0047) and 12 months (- 0.6% vs. - 0.2%, p = 0.0057). Patients in the intervention group showed greater improvement in their ability to self-manage treatment (+ 4.86 vs. + 1.58, p = 0.0014) and in the extent of their knowledge about diabetes (+ 0.6 vs. + 0.2, p < 0.01) at 6 months versus baseline compared with the control group. CONCLUSION: Tailored information provided by the pharmacist to patients with type 2 diabetes did not significantly improve the already high adherence rates, but was associated with a significant decrease in HbA1c and an improvement of patient knowledge about diabetes.

RESUMEN

BACKGROUND: The 6-item Brief Geriatric Assessment (BGA) provides a priori risk stratification of incident hospital health adverse events, but it has not been used yet to assess the risk of unplanned hospital admission for older patients in primary care. This study aims to examine the association between the a priori risk stratification levels of the 6-item BGA performed by general practitioners (GPs) and incident unplanned hospital admissions in older community patients. METHODS: Based on an observational prospective cohort design, 668 participants (mean age 84.7 ± 3.9 years; 64.7% female) were recruited by their GPs during an index primary care visit. The 6-item BGA was completed at baseline and provided an a priori risk stratification in three levels (low, moderate, high). Incident unplanned hospital admissions were recorded during a 6-month follow-up. RESULTS: The incidence of unplanned hospital admissions increased with the risk level of the 6-item BGA stratification, the highest prevalence (35.3%) being reported with the high-risk level (P = 0.001). The risk of unplanned hospital admission at the high-risk level was significant (crude odds ratio (OR) = 5.48, P = 0.001 and fully adjusted OR = 3.71, P = 0.032, crude hazard ratio (HR) = 4.20; P = 0.002 and fully adjusted HR = 2.81; P = 0.035). The Kaplan-Meier's distributions of incident unplanned hospital admissions differed significantly between the three risk levels (P-value = 0.002). Participants with a high-risk level were more frequently admitted to hospital than those at a low-risk level (P = 0.001). Criteria performances of all risk levels were poor, except the specificity of the high-risk level, which was 98.2%. CONCLUSIONS: The a priori 6-item BGA risk stratification was significantly associated with incident unplanned hospital admissions in primary care older patients. However, except for the specificity of the high-risk level, its criteria performances were poor, suggesting that this tool is unsuitable for screening older patients in primary care settings at risk of unplanned hospital admission.

RESUMEN

The impact of patient-physician communication and levels of understanding of treatment on patient knowledge and compliance has been studied in patients undergoing their first cycle of infertility treatment. This observational, real-life, longitudinal study involved 488 patients from 28 infertility centres in France. Data on communication quality, understanding of treatment instructions, patient knowledge and compliance to treatment protocol were collected through questionnaires administered before treatment initiation (V1) and at oocyte retrieval (V2). At V1, patients were very satisfied with their levels of understanding of the injection and monitoring schedules, the information given by the medical team, and the way of receiving instructions, with average ratings on a scale of 0-100% of > 75%. They rated their understanding of possible treatment side-effects as satisfactory (average score 71.1%). Gaps in patient knowledge about their treatment, revealed by discrepancies between physician and patient reports, were observed in 20.5% of patients (n = 79/386), and most commonly resulted from confusion about the units and dose of gonadotropin. Anxiety about performing self-injections and a lack of confidence in their ability to self-inject correctly were each observed in approximately one-third of patients. Patient self-assessment of compliance at V2 revealed that 27% of patients (n = 83/305) did not comply with or had doubts about the injection schedule or dose injected. Meanwhile physicians reported high levels of patient compliance (94.3%; n = 350/371). In conclusion, even when patient-physician relationships appear to be satisfactory, patient miscomprehension and non-compliance during infertility treatment may be underestimated. Further interventions are required to improve these outcomes.

RESUMEN

OBJECTIVES: Our objects was to estimate the direct healthcare costs of type 2 diabetes mellitus (T2DM) in France in 2013. METHODS: Data were drawn from a random sample of ≈600,000 patients registered in the French national health insurances database, which covers 90% of the French population. An algorithm was used to select patients with T2DM. Direct healthcare costs from a collective perspective were derived from the database and compared with those from a control group to estimate the cost of diabetes and related comorbidities. Overall direct costs were also compared according to the diabetes therapies used throughout the year 2013. RESULTS: Cost analysis was available for a sample of 25,987 patients with T2DM (mean age 67.5 ± standard deviation 12.5; 53.9% male) matched with a control group of 76,406 individuals without diabetes. Overall per patient per year medical expenditures were €6506 ± 10,106 in the T2DM group as compared with €3668 ± 6954 in the control group. The cost difference between the two groups was €2838 per patient per year, mainly due to hospitalizations, medication and nursing care costs. Total per capita annual costs were lowest for patients receiving metformin monotherapy (€4153 ± 6170) and highest for those receiving insulin (€12,890). However, apart from patients receiving insulin, costs did not differ markedly across the different oral treatment patterns. CONCLUSION: Extrapolating these results to the whole T2DM population in France, total direct costs of diagnosed T2DM in 2013 was estimated at over €8.5 billion. This estimate highlights the substantial economic burden of this condition on society.

RESUMEN

OBJECTIVE: To define the threshold for excess glucose variability (GV), one of the main features of dysglycemia in diabetes. RESEARCH DESIGN AND METHODS: A total of 376 persons with diabetes investigated at the University Hospital of Montpellier (Montpellier, France) underwent continuous glucose monitoring. Participants with type 2 diabetes were divided into several groups-groups 1, 2a, 2b, and 3 (n = 82, 28, 65, and 79, respectively)-according to treatment: 1) diet and/or insulin sensitizers alone; 2) oral therapy including an insulinotropic agent, dipeptidyl peptidase 4 inhibitors (group 2a) or sulfonylureas (group 2b); or 3) insulin. Group 4 included 122 persons with type 1 diabetes. Percentage coefficient of variation for glucose (%CV = [(SD of glucose)/(mean glucose)] × 100) and frequencies of hypoglycemia (interstitial glucose <56 mg/dL [3.1 mmol/L]) were computed. RESULTS: Percentages of CV (median [interquartile range]; %) increased significantly (P < 0.0001) from group 1 (18.1 [15.2-23.9]) to group 4 (37.2 [31.0-42.3]). In group 1, the upper limit of %CV, which served as reference for defining excess GV, was 36%. Percentages of patients with %CVs above this threshold in groups 2a, 2b, 3, and 4 were 0, 12.3, 19.0, and 55.7%, respectively. Hypoglycemia was more frequent in group 2b (P < 0.01) and groups 3 and 4 (P < 0.0001) when subjects with a %CV >36% were compared with those with %CV ≤36%. CONCLUSIONS: A %CV of 36% appears to be a suitable threshold to distinguish between stable and unstable glycemia in diabetes because beyond this limit, the frequency of hypoglycemia is significantly increased, especially in insulin-treated subjects.

RESUMEN

BACKGROUND: The OPTIMA© (MSD, Courbevoie, France) questionnaire was developed to promote shared decisions and the set-up of specific micro-objectives in clinical practice by optimizing communication between type 2 diabetes (T2DM) patients and their physicians. The present study aimed to assess OPTIMA in clinical practice. METHODS: A cross-sectional multicenter observational study was conducted in France from 2012 to 2014. During routine consultation, patients completed one of the five modules of the OPTIMA questionnaire (Physical activity, Diet, Treatment, Knowledge of the disease or Self-monitoring of blood glucose). The rate of SMART (specific, measurable, acceptable, realistic, timely) micro-objective set-up following the use of the questionnaire was assessed. Data on how patients felt about their diabetes management (beliefs concerning actions, how easy they were to do and how often they were done in practice) were gathered. Finally, patients' and physicians' opinions on OPTIMA were assessed using the PRAgmatic Content and face validity Test (PRAC-Test© (Mapi, Lyon, France) evaluation questionnaire. RESULTS: Overall, 807 patients were included by 186 physicians. While 92.7 % of consultations led to the set-up of a micro-objective, only 22.3 % were SMART micro-objectives: Physical activity module (34.3 %), Diet module (9.6 %), Treatment module (16.4 %), Knowledge of the disease module (25.2 %), and self-monitoring of blood glucose module (29.5 %). Among patients completing the Physical activity module, 79.0 % reported that they believed physical activity was useful, 35.0 % that it was easy, and 25.8 % that they regularly practised it. PRAC-Test results showed that OPTIMA was a useful and easy-to-use questionnaire that promotes communication between physicians and their patients according to 92.8 % of patients and 69.4 % of physicians. CONCLUSION: The OPTIMA questionnaire facilitates communication between patients and their physicians and promotes the set-up of micro-objectives concerning T2DM management. The Physical activity module was the most likely of the five modules in the questionnaire to lead to the set-up of SMART micro-objectives. FUNDING: MSD France.

RESUMEN

AIM: We aimed to compare the frequency of severe hypoglycemia leading to hospitalization (HH) and emergency visits (EV) for any cause in patients with type 2 diabetes mellitus exposed to dipeptidyl peptidase 4 (DPP4) inhibitors (DPP4-i) versus those exposed to insulin secretagogues (IS; sulfonylureas or glinides). METHODS: Data were extracted from the EGB (Echantillon Généraliste des Bénéficiaires) database, comprising a representative sample of ~1% of patients registered in the French National Health Insurance System (~600,000 patients). Type 2 diabetes mellitus patients exposed to regimens containing either a DPP4-i (excluding treatment with IS, insulin, or glucagon-like peptide 1 analog) or IS (excluding treatment with insulin and any incretin therapy) between 2009 and 2012 were selected. HH and EV during the exposure periods were identified in both cohorts. A similar analysis was conducted considering vildagliptin alone versus IS. Comparative analyses adjusting for covariates within the model (subjects matched for key characteristics) and using multinomial regression models were performed. RESULTS: Overall, 7,152 patients exposed to any DPP4-i and 1,440 patients exposed to vildagliptin were compared to 10,019 patients exposed to IS. Eight patients (0.11%) from the DPP4-i cohort and none from the vildagliptin cohort (0.0%) were hospitalized for hypoglycemia versus 130 patients (1.30%) from the IS cohort (138 hospitalizations) (P=0.02 and P<0.0001, respectively). Crude rates of HH/1,000 patient-years were 1.4 (95% CI: 0.7; 2.4) in the DPP4-i cohort, 0.0 in the vildagliptin cohort (95% CI: 0.0; 4.0), versus 5.6 (95% CI, 4.7; 6.6) in the IS cohort (P<0.0001). After adjustments, rates per 1,000 patient-years of HH were 1.4 (95% CI: 0.7; 2.4) with DPP4-i versus 7.5 (95% CI: 6.0; 9.2) with IS (P<0.0001), and 0.0 (95% CI: 0.0; 4.0) with vildagliptin versus 13.6 (95% CI: 10.4; 17.5) with IS (P<0.0001). Adjusted EV rates were also significantly lower with all DPP4-i or with vildagliptin, as compared to IS (P<0.0001). Consistent results were found when considering only treatment initiations for all compared cohorts. CONCLUSION: HH and EV were significantly less frequent in patients exposed to any DPP4-i or to vildagliptin versus IS. These real-life data should be considered in the benefit/risk evaluation of the drugs.

RESUMEN

BACKGROUND: Although physical activity (PA) is key in the management of type 2 diabetes (T2DM) and hypertension, it is difficult to implement in practice. METHODS: Cross-sectional, observational study. Participating physicians were asked to recruit two active and four inactive patients, screened with the Ricci-Gagnon (RG) self-questionnaire (active if score ≥16). Patients subsequently completed the International Physical Activity Questionnaire. The objective was to assess the achievement of individualized glycated hemoglobin and blood pressure goals (<140/90 mmHg) in the active vs inactive cohort, to explore the correlates for meeting both targets by multivariate analysis, and to examine the barriers and motivations to engage in PA. RESULTS: About 1,766 patients were analyzed. Active (n=628) vs. inactive (n=1,138) patients were more often male, younger, less obese, had shorter durations of diabetes, fewer complications and other health issues, such as osteoarticular disorders (P<0.001 for all). Their diabetes and hypertension control was better and obtained despite a lower treatment burden. The biggest difference in PA between the active vs inactive patients was the percentage who declared engaging in regular leisure-type PA (97.9% vs. 9.6%), also reflected in the percentage with vigorous activities in International Physical Activity Questionnaire (59.5% vs. 9.6%). Target control was achieved by 33% of active and 19% of inactive patients (P<0.001). Active patients, those with fewer barriers to PA, with lower treatment burden, and with an active physician, were more likely to reach targets. The physician's role emerged in the motivations (reassurance on health issues, training on hypoglycemia risk, and prescription/monitoring of the PA by the physician). A negative self-image was the highest ranked barrier for the inactive patients, followed by lack of support and medical concerns. CONCLUSION: Physicians should consider PA prescription as seriously as any drug prescription, and take into account motivations and barriers to PA to tailor advice to patients' specific needs and reduce their perceived constraints.

RESUMEN

BACKGROUND: Few data exist examining the management of elderly patients with type 2 diabetes mellitus and renal impairment (RI). This observational study assessed the therapeutic management of this fragile population. METHODS: Cross-sectional study: data from 980 diabetic patients ≥75 years with renal disease are presented. RESULTS: Patients had a mean age of 81 years (range 75-101) with long-standing diabetes (15.4 years) often complicated (half with macrovascular disease). Mean estimated glomerular filtration rate was 43 mL/min/1.73 m(2) and 20% had severe RI. Mean hemoglobin A1c was 7.4%. Anti-diabetic therapy was oral based for 51% of patients (60% ≥2 oral anti-diabetic drugs [OAD]) and insulin based for 49% (combined with OAD in 59%). OAD included metformin (47%), sulfonylureas (26%), glinides (19%), and DPP-4 inhibitors (31%). Treatments were adjusted to increasing RI, with less use of metformin, sulfonylureas, and DPP-4 inhibitors, and more glinides and insulin in severe RI. In all, 579 (60%) of these elderly patients with comorbidities had hemoglobin A1c <7.5% (mean 6.7%) while being intensively treated: 69% under insulin-secretagogues and/or insulin, putting them at high risk for severe hypoglycemia. Only one-fourth were under oral monotherapy. CONCLUSION: In clinical practice, a substantial proportion of elderly patients may be overtreated. RI is insufficiently taken into account when prescribing OAD.

RESUMEN

"Mild dysglycemia" in type 2 diabetes can be defined by the range of HbA1c levels≥6.5% (48 mmol/mol) and<7% (53 mmol/mol), which corresponds to when the risk for vascular complications begins to increase. This "mild dysglycemia" is characterized by both a dawn phenomenon (a spontaneous blood glucose rise in the early morning) and an excess of post-prandial glucose excursions in the absence of abnormal elevation in basal glucose, especially during nocturnal periods. This represents an intermediary stage between pre-diabetes (HbA1c≥5.7%, 39 mmol/mol, and<6.5%, 48 mmol/mol) and those who begin to show a steadily progressive worsening in basal glucose (HbA1c≥7%, 53 mmol/mol). Should this relatively minor intermediate dysglycemic phase deserve more attention, that is the question. The now available incretin-based therapies, and more specifically the DPP-4 inhibitors provide the clinician with the possibility to reduce or eradicate both the dawn phenomenon and post-meal glucose excursions with minimal side effects. The availability of 24-h glycemic profiles in those with "mild dysglycemia" will help to describe their individual glycemic phenotype, based on which the early and appropriate life style changes and/or pharmacological interventions can be introduced.

RESUMEN

INTRODUCTION: In a previously published study, vildagliptin showed a reduced risk of hypoglycemia versus glimepiride as add-on therapy to metformin at similar efficacy. Glimepiride was titrated from a starting dose of 2 mg/day to a maximum dose of 6 mg/day. It is usually assumed that the increased hypoglycemia with glimepiride was driven by the 6 mg/day dose; it was therefore of interest to assess whether the risk of hypoglycemia is also different between vildagliptin and a low (2 mg/day) dose of glimepiride. METHODS: Data (n = 3,059) were from the aforementioned randomized, double-blind study. Comparisons between vildagliptin (50 mg twice daily) and glimepiride (subgroups of patients on 2 mg/day, 6 mg/day, and 'other', and overall glimepiride group) were done by modeling hypoglycemia risk as a function of time and last-measured glycated hemoglobin (HbA1c) using discrete event time modeling, with treatment, age, gender as additional covariates. RESULTS: The hypoglycemia risk was significantly lower in patients receiving vildagliptin versus patients remaining on glimepiride 2 mg/day throughout the study, with similar results unadjusted or adjusted for last HbA1c [adjusted hazard ratio (HR) = 0.06 (95% CI 0.03, 0.11)]. The risk of hypoglycemia was very low with vildagliptin over the full HbA1c range, while the risk with glimepiride 2 mg/day increased with lower HbA1c. The increase for lower levels of HbA1c was more pronounced in the glimepiride 2 mg/day than 6 mg/day subgroup, with the 6 mg/day subgroup showing the lowest hypoglycemia risk among the glimepiride groups [adjusted HR vildagliptin vs. 6 mg/day glimepiride = 0.21 (95% CI 0.11, 0.40)]. CONCLUSION: The data show a substantially lower risk of confirmed hypoglycemia with vildagliptin compared to low-dose (2 mg/day) glimepiride. The analysis indicates that the previously reported results are not driven by high doses of glimepiride and points to interesting differences among patients regarding the susceptibility to hypoglycemia with sulfonylureas.

RESUMEN

BACKGROUND AND AIM: Chronic kidney disease (CKD) is frequent in type 2 diabetes mellitus (T2DM), and therapeutic management of diabetes is more challenging in patients with renal impairment (RI). The place of metformin is of particular interest since most scientific societies now recommend using half the dosage in moderate RI and abstaining from use in severe RI, while the classic contraindication with RI has not been removed from the label. This study aimed to assess the therapeutic management, in particular the use of metformin, of T2DM patients with CKD in real life. METHODS: This was a French cross-sectional observational study: 3,704 patients with T2DM diagnosed for over 1 year and pharmacologically treated were recruited in two cohorts (two-thirds were considered to have renal disease [CKD patients] and one-third were not [non-CKD patients]) by 968 physicians (81% general practitioners) in 2012. RESULTS: CKD versus non-CKD patients were significantly older with longer diabetes history, more diabetic complications, and less strict glycemic control (mean glycated hemoglobin [HbA(1c)] 7.5% versus 7.1%; 25% of CKD patients had HbA1c ≥8% versus 15% of non-CKD patients). Fifteen percent of CKD patients had severe RI, and 66% moderate RI. Therapeutic management of T2DM was clearly distinct in CKD, with less use of metformin (62% versus 86%) but at similar mean daily doses (~2 g/d). Of patients with severe RI, 33% were still treated with metformin, at similar doses. For other oral anti-diabetics, a distinct pattern of use was seen across renal function (RF): use of sulfonylureas (32%, 31%, and 20% in normal RF, moderate RI, and severe RI, respectively) and DPP4-i (dipeptidyl peptidase-4 inhibitors) (41%, 36%, and 25%, respectively) decreased with RF, while that of glinides increased (8%, 14%, and 18%, respectively). CKD patients were more frequently treated with insulin (40% versus 16% of non-CKD patients), and use of insulin increased with deterioration of RF (19%, 39%, and 61% of patients with normal RF, moderate RI, and severe RI, respectively). Treatment was modified at the end of the study-visit in 34% of CKD patients, primarily to stop or reduce metformin. However, metformin was stopped in only 40% of the severe RI patients. CONCLUSION: Despite a fairly good detection of CKD in patients with T2DM, RI was insufficiently taken into account for adjusting anti-diabetic treatment.

RESUMEN

INTRODUCTION: There is an increasing interest for real-life data on drug use in many countries. Reimbursement authorities more and more request observational studies to assess the conditions of use of the products but also to improve knowledge about efficacy and safety in the real world and on a longer term than in clinical trials. AIM: To evaluate the effectiveness, treatment persistence and tolerability of vildagliptin in clinical practice. METHODS: This observational, 2-year prospective cohort study was conducted in France on request of the Health Authorities [Haute Autorite de Sante (HAS)]. Type 2 diabetic mellitus (T2DM) patients initiating vildagliptin (including the fixed combination vildagliptin-metformin) or treated for <6 months were recruited through a national representative sample of general practitioners (GPs) (n = 482) and diabetologists (n = 84) between March 2010 and December 2011. At inclusion and each follow-up visit at ~ 6, 12, 18 and 24 months, a questionnaire was completed by the physician collecting information on socio-demographic, clinical and biological data, treatments and adverse events. RESULTS: 1,700 patients were included: 60% were males, aged 63 ± 11 years, with diabetes duration 7 ± 6 years and body mass index (BMI) 30 ± 6 kg/m(2). 45% were obese, 70% treated for hypertension and 66% for dyslipidemia. 64% of the patients received vildagliptin in dual therapy with metformin. 82% of patients completed the 2-year follow-up. Glycosylated hemoglobin (HbA1c) decreased from a mean baseline of 7.8 ± 1.2% when vildagliptin was started, to 7.0 ± 1.1% at 6 months and remained stable thereafter over 2 years. Mean weight, glomerular filtration rate, liver enzymes, and lipid parameters were unchanged over the study period. Eight patients (0.5%), all concomitantly treated with insulin and/or sulphonylureas, reported one severe hypoglycemia and 47 (2.9%) patients reported 64 non-severe symptomatic hypoglycemia (59% occurred when patients were treated with insulin and/or sulphonylureas). At 6 months, 44.9% of vildagliptin-treated patients reached an HbA1c <7% without hypoglycemia and no weight gain, and this percentage increased to 49.7% at 24 months. Vildagliptin treatment maintenance at 2 years was 88.8% [95% CI (87.2%; 90.4%)], with 4% of patients discontinuing for adverse events. CONCLUSIONS: In everyday conditions of care, vildagliptin efficacy was in line with existing data from randomized clinical trials, sustained over 2 years, with low discontinuation rate and low hypoglycemia risk.

RESUMEN

A large proportion of Muslim patients with type 2 diabetes mellitus (T2DM) elect to fast during the holy month of Ramadan. For these patients hypo- and hyperglycemia constitute two major complications associated with the profound changes in food pattern during the Ramadan fast, and efficacious treatment options with a low risk of hypoglycemia are therefore needed to manage their T2DM as effectively and safely as possible. Dipeptidyl peptidase-4 (DPP-4) inhibitors modulate insulin and glucagon secretion in a glucose-dependent manner, and consequently a low propensity of hypoglycemia has consistently been reported across different patient populations with these agents. Promising data with DPP-4 inhibitors have now also started to emerge in patients with T2DM fasting during Ramadan. The objective of this review is to provide a comprehensive overview of the currently available evidence and potential role of DPP-4 inhibitors in the management of patients with T2DM fasting during Ramadan whose diabetes is treated with oral antidiabetic drugs, and to discuss the mechanistic basis for their beneficial effects in this setting.

RESUMEN

OBJECTIVE: To assess the magnitude of the dawn phenomenon and its impact on the total glucose exposure in type 2 diabetes. RESEARCH DESIGN AND METHODS: A total of 248 noninsulin-treated persons with type 2 diabetes who underwent continuous glucose monitoring were divided into three groups selected by treatments: diet alone (n = 53); insulin sensitizers alone (n = 82); and insulin secretagogues alone or in combination with insulin sensitizers (n = 113). The dawn phenomenon (∂ glucose, mg/dL) was quantified by its absolute increment from nocturnal nadir to prebreakfast value. The participants were secondarily divided into two paired subsets after they had been separated by the presence/absence of a dawn phenomenon based on a threshold of 20 mg/dL and matched for glucose nadir. The impact of the dawn phenomenon was assessed on HbA1c and 24-h mean glucose. RESULTS: The median of ∂ glucose (interquartile range) was 16.0 (0-31.5 mg/dL) in the 248 subjects, and no differences were observed across groups selected by HbA1c or treatments. In the overall population, the mean impacts on HbA1c and 24-h mean glucose were 4.3 ± 1.3 mmol/mol (0.39 ± 0.12%) and 12.4 ± 2.4 mg/dL, respectively. The mean impact on 24-h mean glucose was not statistically different between those on diet alone (16.7 ± 5.9 mg/dL) compared with the two subsets treated with oral hypoglycemic agents (11.2 ± 5.3 and 8.5 ± 7.5 mg/dL). CONCLUSIONS: The impact of the dawn phenomenon on overall glycemic control in type 2 diabetes, as depicted by the HbA1c level, was ∼0.4% and not eliminated by any of the currently available armamentarium of oral antidiabetes agents.
