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.

Background: Several observational studies were conducted with vildagliptin in patients with type 2 diabetes mellitus (T2DM) fasting during Ramadan, showing significantly lower incidences of hypoglycemia with vildagliptin versus sulfonylureas, including gliclazide. It was of interest to complement the existing real-life evidence with data from a randomized, double-blind, clinical trial.Clinical Trials Identifier: NCT01758380.Methods: This multiregional, double-blind study randomized 557 patients with T2DM (mean glycated hemoglobin [HbA1c], 6.9%), previously treated with metformin and any sulfonylurea to receive either vildagliptin (50 mg twice daily) or gliclazide plus metformin. The study included four office visits (three pre-Ramadan) and multiple telephone contacts, as well as Ramadan-focused advice. Hypoglycemic events were assessed during Ramadan; HbA(1c) and weight were analyzed before and after Ramadan.Results: The proportion of patients reporting confirmed (<3.9 mmol/L and/or severe) hypoglycemic events during Ramadan was 3.0% with vildagliptin and 7.0% with gliclazide (P=0.039; one-sided test), and this was 6.0% and 8.7%, respectively, for any hypoglycemic events (P=0.173). The adjusted mean change pre- to post-Ramadan in HbA(1c) was 0.05%±0.04% with vildagliptin and -0.03%±0.04% with gliclazide, from baselines of 6.84% and 6.79%, respectively (P=0.165). In both groups, the adjusted mean decrease in weight was -1.1±0.2 kg (P=0.987). Overall safety was similar between the treatments.Conclusion: In line with the results from previous observational studies, vildagliptin was shown in this interventional study to be an effective, safe, and well-tolerated treatment in patients with T2DM fasting during Ramadan, with a consistently low incidence of hypoglycemia across studies, accompanied by good glycemic and weight control. In contrast, gliclazide showed a lower incidence of hypoglycemia in the present interventional than the previous observational studies. This is suggested to be linked to the specific circumstances of this study, including frequent patient-physician contacts, Ramadan-focused advice, a recent switch in treatment, and very well-controlled patients, which is different from what is often seen in real life.

Background: The purpose of this study was to evaluate the efficacy of vildagliptin 50 mg once daily in patients with severe renal impairment (estimated glomerular filtration rate < 30 mL/min/1.73 m(2)) and longstanding type 2 diabetes not adequately controlled with insulin therapy, which is a difficult-to-treat population, with limited therapeutic options and a high susceptibility to hypoglycemia.Methods: This was a post hoc subanalysis of data obtained during a previously described randomized, double-blind, parallel-group, 24-week study comparing the efficacy and safety of vildagliptin 50 mg once daily versus placebo in patients with type 2 diabetes and moderate or severe renal impairment. The present data derive from 178 patients with severe renal impairment (baseline estimated glomerular filtration rate approximately 21 mL/min/1.73 m(2), 100 randomized to vildagliptin, 78 randomized to placebo), all of whom were receiving insulin therapy (alone or in combination with an oral antidiabetic agent) for longstanding type 2 diabetes (mean approximately 19 years).Results: With vildagliptin in combination with insulin, the adjusted mean change (AMΔ) in HbA(1c) from baseline (7.7% ± 0.1%) was -0.9% ± 0.4% and the between-treatment difference (vildagliptin - placebo) was -0.6% ± 0.2% (P < 0.001). The percentage of patients achieving endpoint HbA(1c) < 7.0% was significantly higher with vildagliptin than placebo (45.2% versus 22.8%, P = 0.008). When added to insulin, vildagliptin and placebo had comparable hypoglycemic profiles and did not cause weight gain. Both treatments were similarly well tolerated, with comparable incidences of adverse events, serious adverse events, and deaths.Conclusion: When added to insulin therapy in patients with severe renal impairment and longstanding type 2 diabetes, vildagliptin 50 mg once daily was efficacious, eliciting HbA(1c) reductions consistent with those previously reported for a patient population with much more recent onset of type 2 diabetes and normal renal function, and had a hypoglycemic profile comparable with placebo. Accordingly, vildagliptin is a suitable treatment option for patients with advanced type 2 diabetes and impaired renal function who require insulin therapy and present a serious therapeutic challenge in clinical practice.

Objective: To examine the effects of dipeptidyl peptidase-IV (DPP-4) inhibition on meal-related beta-cell function and insulin sensitivity over 52 weeks in type 2 diabetes.Research Design and Methods: In a 12-week core study, placebo (n = 51) or vildagliptin (n = 56; 50 mg OD) was added to metformin treatment (1.5-3.0 mg/day). A 40-week extension followed in 71 patients. Meal tests were performed at 0, 12, 24, and 52 weeks; glucose, insulin, and C-peptide were evaluated.Results: In subjects completing 52 weeks with participation in all meal tests (n = 57), HbA(1c) (A1C) decreased in the vildagliptin/metformin group (VM group, n = 31) but increased in the placebo/metformin group (PM group, n = 26; between-group difference -1.0 +/- 0.2%; P < 0.001; baseline of all subjects combined 7.7 +/- 0.1%). Also, fasting glucose decreased in the VM group but increased in the PM group (difference -0.9 +/- 0.3 mmol/l, P = 0.016; baseline 9.8 +/- 0.3 mmol/l). Insulin secretion (postmeal suprabasal area under the 0- to 30-min C-peptide curve divided by the 30-min increase in glucose) was increased in the VM group but was reduced in the PM group (difference +0.011 +/- 0.03 pmol/l 30 min/mmol/l, P = 0.018; baseline 0.036 +/- 0.02). Insulin sensitivity during meal ingestion (oral glucose insulin sensitivity) increased in the VM group but was not altered in the PM group (difference +27 +/- 4 ml x min(-1) x m(-2), P = 0.036; baseline 246 +/- 6). Insulin secretion related to insulin sensitivity (adaptation index) increased in the VM group but decreased in the PM group (difference +3.2 +/- 1.0, P = 0.040; baseline 9.1 +/- 0.5). The change in adaptation index correlated to the change in A1C (r = -0.39, P = 0.004).Conclusions: This study presents evidence that DPP-4 inhibition by vildagliptin when added to metformin in type 2 diabetes over 52 weeks improves beta-cell function along with improved postmeal insulin sensitivity.

Aim: Acute heart failure can be a life‐threatening medical condition. Delaying administration of intravenous furosemide (time‐to‐diuretics) has been postulated to increase mortality, but prior reports have been inconclusive. We aimed to evaluate the association between time‐to‐diuretics and mortality in the international REPORT‐HF registry. Methods and results: We assessed the association of time‐to‐diuretics within the first 24 h with in‐hospital and 30‐day post‐discharge mortality in 15 078 patients from seven world regions in the REPORT‐HF registry. We further tested for effect modification by baseline mortality risk (ADHERE risk score), left ventricular ejection fraction (LVEF) and region. The median time‐to‐diuretics was 67 (25th–75th percentiles 17–190) min. Women, patients with more signs and symptoms of heart failure, and patients from Eastern Europe or Southeast Asia had shorter time‐to‐diuretics. There was no significant association between time‐to‐diuretics and in‐hospital mortality (p > 0.1). The 30‐day mortality risk increased linearly with longer time‐to‐diuretics (administered between hospital arrival and 8 h post‐hospital arrival) (p = 0.016). This increase was more significant in patients with a higher ADHERE risk score (pinteraction = 0.008), and not modified by LVEF or geographic region (pinteraction > 0.1 for both). Conclusion: In REPORT‐HF, longer time‐to‐diuretics was not associated with higher in‐hospital mortality. However, we did found an association with increased 30‐day mortality, particularly in high‐risk patients, and irrespective of LVEF or geographic region.

Background: Atrial fibrillation (AF) and heart failure (HF) each contributes to global disease burden and can coexist. The interplay of prior HF, prior AF, and presenting rhythm have not previously been jointly considered in prognostic implication., Objectives: The authors sought to assess 1-year all-cause mortality according to permutations of prior HF, prior AF, and AF as presenting rhythm, in a global cohort of patients hospitalized for HF., Methods: REPORT-HF enrolled patients during hospitalization for acute HF from 44 countries over 6 continents. Cox proportional hazard models were used to compute HRs for the primary outcome of 1-year all-cause mortality., Results: Of 13,401 participants (median age 67 years, 61% men), 58% had prior HF. AF prevalence (prior or newly detected) at HF admission was 39%, varying by left ventricular ejection fraction and race subgroups. Compared with patients with no prior HF, no prior AF, and presenting in sinus rhythm, 1-year all-cause mortality was elevated in patients with prior HF, prior AF, and presenting in AF (adjusted HR: 1.54 [95% CI: 1.34-1.78]; P < 0.001) and in patients with prior HF, no prior AF, and presenting in AF (adjusted HR: 1.51 [95% CI: 1.20-1.90]; P < 0.001), but not in patients with no prior HF and with prior AF or presenting in AF. These results were conserved across left ventricular ejection fraction and race subgroups., Conclusions: In a global cohort of patients hospitalized for HF, permutations of prior HF, prior AF, and AF as presenting rhythm differentiate outcome. History of prior HF influences the prognostic implications of AF in patients hospitalized for HF.

Background: Outcomes of hospitalized patients with heart failure (HF) and characteristics of advanced HF stage may vary across left ventricular ejection fraction (LVEF) and world regions., Objectives: This study sought to analyze characteristics of hospitalized advanced HF patients across LVEF spectrum, world regions, and country income., Methods: Among 18,553 hospitalized patients with acute HF (7,902 new-onset HF and 10,651 decompensated chronic HF) enrolled in the global registry REPORT-HF (International Registry to Assess Medical Practice With Longitudinal Observation for Treatment of Heart Failure), the authors analyzed characteristics and outcomes of patients with advanced HF, defined as previously diagnosed HF; severe symptoms before current admission (NYHA functional class III/IV); and ≥1 HF-related hospitalization in the preceding 12 months, excluding the current. Differences among hospitalized advanced HF subgroups stratified by LVEF, world region, and country income were examined., Results: Among 6,999 patients with decompensated chronic HF and available previous NYHA functional class and HF hospitalization status, 3,397 (48.5%; 18.3% of the total population) had advanced HF. Of these, 44.5% had severely reduced (≤30%), 34.9% mildly/moderately reduced (31%-49%), and 20.7% preserved (≥50%) LVEF. Patients from Eastern Europe had the lowest 1-year mortality (23%), whereas those from Southeast Asia had the highest (37%). Patients from lower-middle-income countries were younger, with shorter HF duration and lower comorbidity prevalence, received fewer beta-blockers and HF-devices, and had higher 1-year mortality (34%) than upper-middle-income (26%) or high-income countries (27%; P = 0.018). Adjusted 1-year mortality risk did not differ among LVEF subgroups (all P > 0.05), nor did 1-year HF hospitalization rate (P = 0.56)., Conclusions: Hospitalized patients with advanced HF and preserved LVEF had similarly adverse outcomes as those with reduced LVEF. Patients from lower-middle-income countries had less implementation of HF therapies and higher 1-year mortality., Competing Interests: Funding Support and Author Disclosures Novartis Pharma AG sponsored REPORT-HF.

Background: Heart Failure (HF) quality of care (QoC) is associated with clinical outcomes. Therefore, we investigated differences in HF QoC across worldwide regions (with differing national income) and the association of quality indicators with outcomes., Methods: We examined the quality of care (QoC) in acute heart failure (HF) patients across different regions using quality indicators (QIs) from the European Society of Cardiology (ESC) and the American Heart Association (AHA) to evaluate QoC. The analysis included 17,632 patients enrolled from 358 medical centres in 44 countries between 23 July 2014 and 24 March 2017, all part of the prospective REPORT-HF cohort study. We investigated how QoC varied by region and its relationship with mortality rates at 30 days and 1 year after hospital discharge. For each QI, percentage attainment of QI among eligible patients was calculated and compared across regions., Findings: Among 17,632 patients (median age: 67 years; 61% women) followed up for a median of two years, we assessed 16 QIs. QIs that were least often achieved included measurement of natriuretic peptides, performance of echocardiography, treatment with guideline medical therapy, and a scheduled follow-up consultation after discharge. QI achievement was significantly lower in lower-than higher-income countries. Higher (≥50% vs. <50%) achievement of cumulative QIs was associated with lower 30-day (hazard ratio [HR] 0.58, 95% Confidence Interval [CI] 0.40-0.83; p < 0.001), and 1-year mortality (HR 0.58, 95% CI 0.50-0.68; p < 0.001)., Interpretation: QoC is lower in lower-than higher-income countries and lower QoC is associated with worse outcomes. Improving QoC by addressing structural barriers and quality improvement programs may improve the outcomes of patients with HF., Funding: Novartis., Competing Interests: CSPL is supported by a Clinician Scientist Award from the National Medical Research Council of Singapore; has Received research support from NovoNordisk and Roche Diagnostics; has Served as consultant or on the Advisory Board/Steering Committee/Executive Committee for Alleviant Medical, Allysta Pharma, AnaCardio AB, Applied Therapeutics, AstraZeneca, Bayer, Biopeutics, Boehringer Ingelheim, Boston Scientific, Bristol Myers Squibb, CardioRenal, Eli Lilly, Impulse Dynamics, Intellia Therapeutics, Ionis Pharmaceutical, Janssen Research & Development LLC, Medscape/WebMD Global LLC, Merck, Novartis, Novo Nordisk, Prosciento Inc, Quidel Corporation, Radcliffe Group Ltd., Recardio Inc, ReCor Medical, Roche Diagnostics, Sanofi, Siemens Healthcare Diagnostics and Us2.ai; and serves as co-founder & non-executive director of Us2.ai.

Background: Multimorbidity (two or more comorbidities) is common among patients with acute heart failure, but comprehensive global information on its prevalence and clinical consequences across different world regions and income levels is scarce. This study aimed to investigate the prevalence of multimorbidity and its effect on pharmacotherapy and prognosis in participants of the REPORT-HF study., Methods: REPORT-HF was a prospective, multicentre, global cohort study that enrolled adults (aged ≥18 years) admitted to hospital with a primary diagnosis of acute heart failure from 358 hospitals in 44 countries on six continents. Patients who currently or recently participated in a clinical treatment trial were excluded. Follow-up data were collected at 1-year post-discharge. The primary outcome was 1-year post-discharge mortality. All patients in the REPORT-HF cohort with full data on comorbidities were eligible for the present study. We stratified patients according to the number of comorbidities, and countries by world region and country income level. We used one-way ANOVA, χ 2 test, or Mann-Whitney U test for comparisons between groups, as applicable, and Cox regression to analyse the association between multimorbidity and 1-year mortality., Findings: Between July 23, 2014, and March 24, 2017, 18 553 patients were included in the REPORT-HF study. Of these, 18 528 patients had full data on comorbidities, of whom 11 360 (61%) were men and 7168 (39%) were women. Prevalence rates of multimorbidity were lowest in southeast Asia (72%) and highest in North America (92%). Fewer patients from lower-middle-income countries had multimorbidity than patients from high-income countries (73% vs 85%, p<0·0001). With increasing comorbidity burden, patients received fewer guideline-directed heart failure medications, yet more drugs potentially causing or worsening heart failure. Having more comorbidities was associated with worse outcomes: 1-year mortality increased from 13% (no comorbidities) to 26% (five or more comorbidities). This finding was independent of common baseline risk factors, including age and sex. The population-attributable fraction of multimorbidity for mortality was higher in high-income countries than in upper-middle-income or lower-middle-income countries (for patients with five or more comorbidities: 61% vs 27% and 31%, respectively)., Interpretation: Multimorbidity is highly prevalent among patients with acute heart failure across world regions, especially in high-income countries, and is associated with higher mortality, less prescription of guideline-directed heart failure pharmacotherapy, and increased use of potentially harmful medications., Funding: Novartis Pharma., Translations: For the Arabic, French, German, Hindi, Mandarin, Russian and Spanish translations of the abstract see Supplementary Materials section., Competing Interests: Declaration of interests JGFC reports grants and personal fees from Amgen, Bayer, Bristol Myers Squibb, and Torrent Pharmaceuticals; personal fees from AstraZeneca, Myokardia, Servier, and Abbott; grants, personal fees, and non-financial support from Medtronic, Novartis, and Vifor; and grants and non-financial support from Pharmacosmos and PharmaNord.

Background: Previous reports suggest that risk factors, management, and outcomes of acute heart failure (AHF) may differ by sex, but they rarely extended analysis to low- and middle-income countries., Objectives: In this study, the authors sought to analyze sex differences in treatment and outcomes in patients hospitalized for AHF in 44 countries., Methods: The authors investigated differences between men and women in treatment and outcomes in 18,553 patients hospitalized for AHF in 44 countries in the REPORT-HF (Registry to Assess Medical Practice With Longitudinal Observation for the Treatment of Heart Failure) registry stratified by country income level, income disparity, and world region. The primary outcome was 1-year all-cause mortality., Results: Women (n = 7,181) were older than men (n = 11,372), were more likely to have heart failure with preserved left ventricular ejection fraction, had more comorbid conditions except for coronary artery disease, and had more severe signs and symptoms at admission. Coronary angiography, cardiac stress tests, and coronary revascularization were less frequently performed in women than in men. Women with AHF and reduced left ventricular ejection fraction were less likely to receive an implanted device, regardless of region or country income level. Women were more likely to receive treatments that could worsen HF than men (18% vs 13%; P < 0.0001). In countries with low-income disparity, women had better 1-year survival than men. This advantage was lost in countries with greater income disparity (P interaction  < 0.001)., Conclusions: Women were less likely to have diagnostic testing or receive guideline-directed care than men. A survival advantage for women was observed only in countries with low income disparity, suggesting that equity of HF care between sexes remains an unmet goal worldwide., Competing Interests: Funding Support and Author Disclosures REPORT-HF was funded by Novartis Pharma.

Objectives: The primary aim of the current study was to investigate global differences in prevalence, association with outcome, and treatment of ischemic heart disease (IHD) in patients with acute heart failure (AHF) in the REPORT-HF (International Registry to Assess Medical Practice With Longitudinal Observation for Treatment of Heart Failure) registry., Background: Data on IHD in patients with AHF are primarily from Western Europe and North America. Little is known about global differences in treatment and prognosis of patients with IHD and AHF., Methods: A total of 18,539 patients with AHF were prospectively enrolled from 44 countries and 365 centers in the REPORT-HF registry. Patients with a history of coronary artery disease, an ischemic event causing admission for AHF, or coronary revascularization were classified as IHD. Clinical characteristics, treatment, and outcomes of patients with and without IHD were explored., Results: Compared with 8,766 (47%) patients without IHD, 9,773 (53%) patients with IHD were older, more likely to have a left ventricular ejection fraction <40% (heart failure with reduced ejection fraction [HFrEF]), and reported more comorbidities. IHD was more common in lower income compared with high-income countries (61% vs. 48%). Patients with IHD from countries with low health care expenditure per capita or without health insurance less likely underwent coronary revascularization or used anticoagulants at discharge. IHD was independently associated with worse cardiovascular death (hazard ratio: 1.21; 95% confidence interval: 1.09 to 1.35). The association between IHD and cardiovascular death was stronger in HFrEF compared with heart failure with preserved ejection fraction (p interaction  <0.001)., Conclusions: In this large global contemporary cohort of patients with AHF, IHD was more common in low-income countries and conveyed worse 1-year mortality, especially in HFrEF. Patients in regions with the greatest burden of IHD were less likely to receive coronary revascularization and treatment for IHD., Competing Interests: Funding Support and Author Disclosures REPORT-HF was funded by Novartis.

Background: Heart failure is a global public health problem, affecting a large number of individuals from low-income and middle-income countries. REPORT-HF is, to our knowledge, the first prospective global registry collecting information on patient characteristics, management, and prognosis of acute heart failure using a single protocol. The aim of this study was to investigate differences in 1-year post-discharge mortality according to region, country income, and income inequality., Methods: Patients were enrolled during hospitalisation for acute heart failure from 358 centres in 44 countries on six continents. We stratified countries according to a modified WHO regional classification (Latin America, North America, western Europe, eastern Europe, eastern Mediterranean and Africa, southeast Asia, and western Pacific), country income (low, middle, high) and income inequality (according to tertiles of Gini index). Risk factors were identified on the basis of expert opinion and knowledge of the literature., Findings: Of 18 102 patients discharged, 3461 (20%) died within 1 year. Important predictors of 1-year mortality were old age, anaemia, chronic kidney disease, presence of valvular heart disease, left ventricular ejection fraction phenotype (heart failure with reduced ejection fraction [HFrEF] vs preserved ejection fraction [HFpEF]), and being on guideline-directed medical treatment (GDMT) at discharge (p<0·0001 for all). Patients from eastern Europe had the lowest 1-year mortality (16%) and patients from eastern Mediterranean and Africa (22%) and Latin America (22%) the highest. Patients from lower-income countries (ie, ≤US$3955 per capita; hazard ratio 1·58, 95% CI 1·41-1·78), or with greater income inequality (ie, from the highest Gini tertile; 1·25, 1·13-1·38) had a higher 1-year mortality compared with patients from regions with higher income (ie, >$12 235 per capita) or lower income inequality (ie, from the lowest Gini tertile). Compared with patients with HFrEF, patients with HFpEF had a lower 1-year mortality with little variation by income level (p interaction for HFrEF vs HFpEF <0·0001)., Interpretation: Acute heart failure is associated with a high post-discharge mortality, particularly in patients with HFrEF from low-income regions with high income inequality. Regional differences exist in the proportion of eligible patients discharged on GDMT, which was strongly associated with mortality and might reflect lack of access to post-discharge care and prescribing of GDMT., Funding: Novartis Pharma., (Copyright © 2020 The Author(s).

Objective: This study was conducted to characterize the effects of vildagliptin on beta-cell function in patients with type 2 diabetes and mild hyperglycemia., Design: A 52-wk double-blind, randomized, parallel-group study comparing vildagliptin (50 mg every day) and placebo was conducted in 306 patients with mild hyperglycemia (glycosylated hemoglobin of 6.2-7.5%). Plasma glucose and C-peptide levels were measured during standard meal tests performed at baseline, wk 24 and 52, and after 4-wk washout. Insulin secretory rate (ISR) was calculated by C-peptide deconvolution, and beta-cell function was quantified with a mathematical model that describes ISR as a function of absolute glucose levels (insulin secretory tone and glucose sensitivity), the glucose rate of change (rate sensitivity), and a potentiation factor., Results: Vildagliptin significantly increased fasting insulin secretory tone [between-group difference in adjusted mean change from baseline to wk 52 (AM Delta) = +34.1 +/- 9.5 pmol.min(-1).m(-2), P < 0.001] glucose sensitivity (AM Delta = +20.7 +/- 5.2 pmol.min(-1).m(-2).mm(-1), P < 0.001), and rate sensitivity (AM Delta = +163.6 +/- 67.0 pmol.m(-2).mm(-1), P = 0.015), but total insulin secretion (ISR area under the curve at 0-2 h) and the potentiation factor excursion during meals were unchanged. These improvements in beta-cell function were accompanied by a decrease in the glucose area under the curve at 0-2 h (AM Delta = -1.7 +/- 0.5 mm/h, P = 0.002) and in glycosylated hemoglobin (AM Delta = -0.3 +/- 0.1%, P < 0.001). None of the effects of vildagliptin remained after 4-wk washout from study medication., Conclusions: Consistent with previous findings from shorter-term studies in patients with more severe hyperglycemia, in patients with mild hyperglycemia, improved beta-cell function is maintained throughout 52-wk treatment with vildagliptin and underlies a sustained improvement in glycemic control. However, no effects remain after washout.
