Abstract
Sitagliptin has been suggested as a treatment option for older adults with type 2 diabetes (T2D). However, no randomized controlled trial has been performed to evaluate the efficacy and safety of sitagliptin treatment in older Japanese patients with T2D. The STREAM study was a multicenter, open-label, randomized controlled trial. T2D outpatients aged 65-80 years with moderately controlled glycemic levels (HbA1c 7.4-10.4%) under lifestyle interventions without or with oral anti-diabetic drugs excluding DPP4 inhibitors or GLP-1 receptor agonists were recruited (n = 176). The participants were randomized into sitagliptin group (n = 88) who received sitagliptin as an initial or an additive anti-diabetic drug and control group (n = 88) who did not. The treatment goal was HbA1c level < 7.4%. Efficacy and safety during 12-month treatment period were investigated. The mean (± SD) ages were 70.6 ± 3.9 and 71.9 ± 4.4 years old in sitagliptin and control groups, respectively. According to a mixed-effects model analysis, average changes from baseline over the treatment period in fasting plasma glucose (FPG), HbA1c, and glycated albumin (GA) were - 27.2 mg/dL, - 0.61%, and - 2.39%, respectively, in sitagliptin group, and 0.50 mg/dL, - 0.29%, and - 0.93%, respectively, in control group. The reductions in FPG, HbA1c, and GA were significantly greater in sitagliptin group (P < 0.0001, P < 0.01, and P < 0.0001, respectively). There were no differences in the incidence of adverse effects, except for cystatin C elevation and platelet count reduction in sitagliptin group. Sitagliptin treatment effectively improved the glycemic profile without any serious adverse effects in older T2D patients.Trial registration number: UMIN000010376.

The Effects of Dipeptidyl Peptidase 4 Inhibitors on Renal Function in Patients with Type 2 Diabetes Mellitus. J Clin Med 2022; 11:jcm11092653. [PMID: 35566779 PMCID: PMC9101888 DOI: 10.3390/jcm11092653] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Revised: 04/24/2022] [Accepted: 05/06/2022] [Indexed: 12/19/2022] Open
Abstract
Past studies have confirmed that glucagon-like peptide 1 (GLP-1) receptor agonists can improve renal outcomes in patients with type 2 diabetes mellitus (DM). This study aimed to evaluate whether dipeptidyl peptidase 4 (DPP-4) inhibitors, which elevate GLP-1 levels, also have similar effects on renal function. In this retrospective study, diabetic patients treated with anti-hyperglycemic agents between 2008 and 2011 were selected. We compared the time to first occurrence of estimated glomerular filtration rate (eGFR) decline ≥30% from the baseline between patients treated with DPP-4 inhibitors and those treated with other anti-hyperglycemic drugs. A total of 2202 patients were enrolled. The incidence of eGFR decline ≥30% from the baseline was 10.08% in the DPP-4 inhibitor group and 16.17% in the non-DPP-4 inhibitor group (p < 0.001). The mean time to event was significantly longer in patients receiving DPP-4 inhibitors (2.84 ± 1.60 vs. 1.96 ± 1.30 years, p < 0.001). Patients who were younger than 65 years old, had better baseline eGFR, did not have preexisting hyperlipidemia, or who were untreated with concomitant statin showed greater reductions in the risk of renal function decline (all p for interaction < 0.05). Conclusively, DPP-4 inhibitors used alone or in combination with other glucose-lowering agents were correlated with lower risks of eGFR decline in patients with type 2 DM.

Abstract
BACKGROUND The prevalence of diabetes mellitus has been increased dramatically which in turn leads to complications including cardiovascular diseases, diabetic kidney disease, and substantially end-stage renal disease. METHODS We reviewed articles discussing the pathophysiology of diabetic nephropathy with new agents that may be useful in the management of the disease. We used PubMed, Scopus, Google Scholar and the Open-access searching engines. RESULTS The recent recommendations primarily depend on glycaemic and blood pressure control and the use of standard renin-angiotensin system blockade. Currently, the use of agents with nephroprotective effects beyond the hyperglycaemic lowering effect has been evidenced clinically. CONCLUSIONS In his review, the pathophysiology, clinical manifestations, and lines of treatment of diabetic nephropathy are discussed. In addition, a focus on the clinical role and nephroprotective effects of the emerging therapeutic class, dipeptidyl peptidase IV (DPP-4) inhibitors, is addressed in detail.

Diabetes Ther 2021; 12:655-667. [PMID: 33474645 PMCID: PMC7947073 DOI: 10.1007/s13300-020-00991-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Accepted: 12/19/2020] [Indexed: 11/25/2022] Open
Abstract
INTRODUCTION Dipeptidyl peptidase 4 (DPP4) inhibitors are widely used in patients with type 2 diabetes mellitus (T2DM) on maintenance hemodialysis (HD), but the efficacy of the once-weekly DPP4 inhibitor omarigliptin is not known. METHODS This prospective, randomized, open-label, parallel-group, non-inferiority/superiority, once-daily DPP4 inhibitor linagliptin-controlled, multicenter study examined glycemic control and safety of omarigliptin (UMIN000024284). Sample size was calculated to confirm non-inferiority in terms of changes in glycated hemoglobin (HbA1c). We enrolled 33 patients with T2DM on maintenance HD who had been treated with linagliptin for at least 3 months. The patients were randomized to receive omarigliptin (12.5 mg/week; n = 16) or linagliptin (5 mg/day; n = 17). Primary endpoints were changes in HbA1c and glycoalbumin (GA) over 24 weeks. RESULTS Differences in the mean change in primary endpoint values between the omarigliptin and linagliptin groups were - 0.61% [- 1.14, - 0.09] for HbA1c, with a two-tailed upper 95% limit (i.e., one-tailed 97.5% upper limit) of 0.25%, below the non-inferiority limit, and - 1.67% [- 4.23, + 0.88] for GA, with a two-tailed upper 95% limit of 0.75%, above the non-inferiority limit. At 24 weeks, the omarigliptin group showed significantly greater reduction in HbA1c than the linagliptin group (- 0.2% ± 0.6% vs. 0.4% ± 0.8%, two-tailed p = 0.024) and significantly greater reduction in blood glucose after a single HD session (- 18.4 ± 31.4 mg/dL vs. 25.2 ± 59.5 mg/dL, respectively, two-tailed p = 0.019). No subjects in the omarigliptin group developed hypoglycemia. CONCLUSIONS Our data showed that omarigliptin was non-inferior to linagliptin in glycemic control. Omarigliptin is feasible for glycemic control in patients with T2DM on maintenance HD. CLINICAL TRIALS REGISTRATION UMIN000024284.

Is there a Chance to Promote Arteriogenesis by DPP4 Inhibitors Even in Type 2 Diabetes? A Critical Review. Cells 2018; 7:cells7100181. [PMID: 30360455 PMCID: PMC6210696 DOI: 10.3390/cells7100181] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2018] [Revised: 10/08/2018] [Accepted: 10/18/2018] [Indexed: 12/18/2022] Open
Abstract
Cardiovascular diseases (CVD) are still the prevailing cause of death not only in industrialized countries, but even worldwide. Type 2 diabetes mellitus (type 2 DM) and hyperlipidemia, a metabolic disorder that is often associated with diabetes, are major risk factors for developing CVD. Recently, clinical trials proved the safety of gliptins in treating patients with type 2 DM. Gliptins are dipeptidyl-peptidase 4 (DPP4/CD26) inhibitors, which stabilize glucagon-like peptide-1 (GLP-1), thereby increasing the bioavailability of insulin. Moreover, blocking DPP4 results in increased levels of stromal cell derived factor 1 (SDF-1). SDF-1 has been shown in pre-clinical animal studies to improve heart function and survival after myocardial infarction, and to promote arteriogenesis, the growth of natural bypasses, compensating for the function of an occluded artery. Clinical trials, however, failed to demonstrate a superiority of gliptins compared to placebo treated type 2 DM patients in terms of cardiovascular (CV) outcomes. This review highlights the function of DPP4 inhibitors in type 2 DM, and in treating cardiovascular diseases, with special emphasis on arteriogenesis. It critically addresses the potency of currently available gliptins and gives rise to hope by pointing out the most relevant questions that need to be resolved.
