AbstractThe objective of this paper was to review the adherence and persistence rates of major antidiabetic medication classes (i.e., metformin, sulfonylureas, sodium glucose cotransporter-2 inhibitors, dipeptidyl peptidase-4 inhibitors, insulin, glucagon-like peptide-1 receptor agonists, and thiazolidinediones) by summarizing the major findings of the studies published since 2017. In addition, we reported the potential causes for low adherence and persistence of antidiabetic medications. Based on the literature, the highest rate of adherence and persistence was consistently observed in metformin users. Second to metformin were sodium glucose cotransporter-2 inhibitors. Injectable therapies such as insulin and glucagon-like peptide-1 receptor agonists trailed low on the adherence and persistence rates. To the best of our knowledge, no studies published since the year 2017 analyzed the adherence and persistence of thiazolidinediones independently. The most frequently cited cause for low adherence and persistence was the severity of adverse events. Baseline characteristics (e.g., baseline HbA1c level), demographic information (e.g., age, gender, or ethnicity), and comorbidity profiles also had significant impacts on adherence and persistence in patients with type 2 diabetes mellitus.

Background: The effectiveness of glucose-lowering drugs (GLDs) is unknown among patients with dementia. Objective: To analyze all-cause mortality among users of six GLDs in dementia and dementia-free subjects, respectively. Methods: This was a longitudinal open-cohort registry-based study using data from the Swedish Dementia Registry, Total Population Register, and four supplemental registers providing data on dementia status, drug usage, confounders, and mortality. The cohort comprised 132,402 subjects with diabetes at baseline, of which 11,401 (8.6%) had dementia and 121,001 (91.4%) were dementia-free. Subsequently, comparable dementia – dementia-free pairs were sampled. Then, as-treated and intention-to-treat exposures to metformin, insulin, sulfonylurea, dipeptidyl-peptidase-4 inhibitors, glucagon-like peptide-1 analogues (GLP-1a), and sodium-glucose cotransporter-2 inhibitors (SGLT-2i) were analyzed in the parallel dementia and dementia-free cohorts. Confounding was addressed using inverse-probability weighting and propensity-score matching, and flexible parametric survival models were used to produce hazard ratios (HR) and 95% confidence intervals (CI) of the association between GLDs and all-cause mortality. Results: In the as-treated models, increased mortality was observed among insulin users with dementia (HR 1.34 [95%CI 1.24–1.45]) as well as in dementia-free subjects (1.54 [1.10–1.55]). Conversely, sulfonylurea was associated with higher mortality only in dementia subjects (1.19 [1.01–1.42]). GLP-1a (0.44 [0.25–0.78]) and SGLT-2i users with dementia (0.43 [0.23–0.80]) experienced lower mortality compared to non-users. Conclusion: Insulin and sulfonylurea carried higher mortality risk among dementia patients, while GLP-1a and SGLT-2i were associated with lower risk. GLD-associated mortality varied between dementia and comparable dementia-free subjects. Further studies are needed to optimize GLD use in dementia patients.

Polycystic ovary syndrome (PCOS) is an endocrine-gynecology disorder affecting many women of childbearing age. Although a part of the involved mechanism in PCOS occurrence is discovered, the exact etiology and pathophysiology are not comprehensively understood yet. We searched PubMed for PCOS pathogenesis and management in this article and ClinicalTrials.gov for information on repurposed medications. All responsible factors behind PCOS were thoroughly evaluated. Furthermore, the complete information on PCOS commonly prescribed and repurposed medications is summarized through tables. Epigenetics, environmental toxicants, stress, diet as external factors, insulin resistance, hyperandrogenism, inflammation, oxidative stress, and obesity as internal factors were investigated. Lifestyle modifications and complementary and alternative medicines are preferred first-line therapy in many cases. Medications, including 3-hydroxy-3-methyl-3-glutaryl-coenzyme A (HMG-CoA) reductase inhibitors, thiazolidinediones, sodium-glucose cotransporter-2 inhibitors, dipeptidyl peptidase-4 inhibitors, glucose-like peptide-1 receptor agonists, mucolytic agents, and some supplements have supporting data for being repurposed in PCOS. Since there are few completed clinical trials with a low population and mostly without results on PCOS repurposed medications, it would be helpful to do further research and run well-designed clinical trials on this subject. Moreover, understanding more about PCOS would be beneficial to find new medications implying the effect via the novel discovered routes.

Inflammatory bowel disease (IBD) is a comprehensive term for chronic or relapsing inflammatory diseases occurring in the intestinal tract, generally including Crohn’s disease (CD) and ulcerative colitis (UC). Presently, the pathogenesis of IBD is unknown, yet multiple factors have been reported to be related with the development of IBD. Flavonoids are phytochemicals with biological activity, which are ubiquitously distributed in edible plants, such as fruits and vegetables. Recent studies have demonstrated impressively that flavonoids have anti-IBD effects through multiple mechanisms. These include anti-inflammatory and antioxidant actions; the preservation of the epithelial barrier integrity, the intestinal immunomodulatory property, and the shaping microbiota composition and function. In addition, a few studies have shown the impact of flavonoids on enterohormones release; nonetheless, there is hardly any work showing the link between flavonoids, enterohormones release and IBD. So far, the interaction between flavonoids, enterohormones and IBD is elucidated for the first time in this review. Furthermore, the inference can be drawn that flavonoids may protect against IBD through modulating enterohormones, such as glucagon-like peptide 1 (GLP-1), GLP-2, dipeptidyl peptidase-4 inhibitors (DPP-4 inhibitors), ghrelin and cholecystokinin (CCK). In conclusion, this manuscript explores a possible mechanism of flavonoids protecting against IBD.

Background: Diabetes affects millions of people worldwide, with predicted numbers of about 700 million adults affected by 2045. Among the several anti-diabetic drug therapies available in the market, Dipeptidyl Peptidase-4 (DPP-4) inhibitors have emerged as a promising therapeutic approach with scope for exploration in the segment of peptidomimetics. Objective: Series of proline-containing peptidomimetic compounds were designed and investigated for their drug-likeness through Lipinski’s rule of five, lead-likeness through the rule of three, predictive pharmacokinetic studies (absorption, distribution, metabolism, and excretion), and toxicity properties through in-silico approaches. The designed compounds were evaluated for their interactions with binding sites of the enzyme DPP-4 using an extra precision docking approach. Methods: Proline-containing peptidomimetic compounds were designed rationally. Drug-likeness and lead-likeness properties were calculated using Schrödinger Maestro v11.2 software. ADME and toxicity properties were predicted using PreADMET version 2.0. Docking study was performed using Schrödinger Maestro v11.2 software, and ligands for the study were designed using MarvinSketch software. Results: 5(S)-methyl-L-proline containing 17 ligands were designed. All of them were found to obey Lipinski’s rule of five. Compounds were found to have good ADME profile and low toxicity predictions. Conclusion: Four compounds were found to have good interactions with DPP-4 binding sites and hence created the scope to develop a DPP-4 inhibitors containing 5(S)-methyl-L-proline moiety.

: Dipeptidyl peptidase-4 inhibitors (DDP-4Is) or gliptins have been extensively studied in recent years. These studies have shown the safety and efficacy of gliptins in managing hyperglycemia in diabetic patients. However, there is ongoing debate on whether DDP-4Is are associated with a higher risk for developing heart failure. It is expected that long-term data from patients who are currently prescribed DDP-4Is will provide a clearer understanding of their potential benefits. This should also help guide the development of future guidelines. The focus of this perspective is on associations between the “use of DPP-4Is” and “increased risk of heart failure”. Thus, we examine several key publications and reviews on clinical trials on this class of oral antidiabetic medications. For this communication, the pertinent literature has been critically analyzed to provide an evidence-based overview of the evolving concept of DPP-4Is-induced risk of heart failure.

Diabetes is a driver of non-alcoholic fatty liver disease (NAFLD) and fibrosis. We determine current practices in examining liver fibrosis in people with diabetes and record prevalence levels in primary and secondary care. We extracted HbA1c results ≥48 mmol/mol to identify people with diabetes, then examined the proportion who had AST, ALT, and platelets results, facilitating calculation of non-invasive fibrosis tests (NIT), or an enhanced liver fibrosis score. Fibrosis markers were requested in only 1.49% (390/26,090), of which 29.7% (n = 106) had evidence of significant fibrosis via NIT. All patients at risk of fibrosis had undergone transient elastography (TE), biopsy or imaging. TE and biopsy data showed that 80.6% of people with raised fibrosis markers had confirmed significant fibrosis. We also show that fibrosis levels as detected by NIT are marginally lower in patients treated with newer glucose lowering agents (sodium-glucose transporter protein 2 inhibitors, dipeptidyl peptidase-4 inhibitors and glucagon-like peptide-1 receptor agonists). In conclusion by utilising a large consecutively recruited dataset we demonstrate that liver fibrosis is infrequently screened for in patients with diabetes despite high prevalence rates of advanced fibrosis. This highlights the need for cost-effectiveness analyses to support the incorporation of widespread screening into national guidelines and the requirement for healthcare practitioners to incorporate NAFLD screening into routine diabetes care.

Aim: Study aims to assess amylase, lipase of patients with Type 2 diabetes under different types of treatments. Materials & methods: Patients’ treatment modalities including insulin, metformin, pioglitazone, sodium-glucose co-transporter-2 inhibitors, insulin secretagogues, dipeptidyl peptidase-4 inhibitors and glucagon like peptide-1 receptor agonists were compared. Results: There was no difference in amylase and lipase levels between dipeptidyl peptidase-4 inhibitor users and non-users (p = 0.2, p = 0.3, respectively) and glucagon like peptide-1 analog users and non-users (p = 0.1, p = 0.7, respectively). Patients who use insulin secretagogues had significantly higher amylase, lipase and (77.2 ± 39.8 vs 69.5 ± 33.0, p = 0,038 and 47.2 ± 33.2 vs 39.6 ± 26.8, p = 0.01, respectively) patients on basal insulin had lower amylase levels (69.9 ± 37.7 vs 77.2 ± 33.7, p = 0.014). Conclusion: Incretin-based therapies showed no difference in amylase and lipase levels whereas there was increase with secretagogues and decrease with basal insulin.

There is a significant increase noted in the incidence and prevalence of Type 2 diabetes mellitus (T2DM). The global number of diabetic patients is projected by the International Diabetes Federation (IDF) to reach 552 million. T2DM disease has chronic and progressive nature. More than fifty percent of patients do not attain adequate glycemic control despite initial sufficient monotherapy. To maintain target glycated hemoglobin (HbA1c) levels (<7%), dose adjustment and adoption of several diabetes therapies become necessary in many cases. Compared to monotherapy, a fixed drug combination of oral agents and metformin has proven to be more efficacious to maintain levels of blood glucose and HbA1c. The combination of dipeptidyl peptidase-4 inhibitors (DDPIs) and metformin has been explicated to effectively decrease HbA1c to a relatively higher degree compared to the use of either agent individually. This combination addresses various pathophysiological processes involved in T2DM pathogenesis. Additionally, the concerned combination is safe and associated with a lower risk of hypoglycemia. Moreover, it is well-tolerated and prescribed as an easy-to-use single pill to improve patient compliance. This review provides an overview of the pharmacology, efficacy, and safety of fixed drug combinations of DDPIs and metformin according to current practice.
