Costs and Treatment Pathways for Type 2 Diabetes in the UK: A Mastermind Cohort Study

Risk of Lactic Acidosis in Hospitalized Diabetic Patients Prescribed Biguanides in Japan: A Retrospective Total-Population Cohort Study

Patient data from the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) are used to assess the effect of biguanide administration on rates of lactic acidosis (LA) in hospitalized diabetes mellitus (DM) patients. In this retrospective cohort study (from April 2013 to March 2016), we compare DM inpatients prescribed biguanides to DM inpatients who were not prescribed biguanides to quantify the association between biguanides and incidence of LA. In total, 8,111,848 DM patient records are retrieved from the NDB. Of the 528,768 inpatients prescribed biguanides, 782 develop LA. Of the 1,967,982 inpatients not prescribed biguanides, 1310 develop LA. The rate ratio of inpatients who develop LA and are administered biguanides to those who developed LA without receiving biguanides is 1.44 (95% CI, 1.32-1.58). Incidence rates and rate ratios for both sexes are elevated in the group prescribed biguanides for patients aged 70 years and older, markedly in those 80 years and older: 40.12 and 6.31 (95% CI, 4.75-8.39), respectively, for men and 34.96 and 5.40 (95% CI, 3.91-7.46), respectively, for women. Biguanides should be used conservatively in patients older than 70 years, particularly for those with comorbidities, and with caution in patients 80 years and older.

Trends in Antidiabetic Drug Discovery: FDA Approved Drugs, New Drugs in Clinical Trials and Global Sales

Type 2 diabetes mellitus (T2DM) continues to be a substantial medical problem due to its increasing global prevalence and because chronic hyperglycemic states are closely linked with obesity, liver disease and several cardiovascular diseases. Since the early discovery of insulin, numerous antihyperglycemic drug therapies to treat diabetes have been approved, and also discontinued, by the United States Food and Drug Administration (FDA). To provide an up-to-date account of the current trends of antidiabetic pharmaceuticals, this review offers a comprehensive analysis of the main classes of antihyperglycemic compounds and their mechanisms: insulin types, biguanides, sulfonylureas, meglitinides (glinides), alpha-glucosidase inhibitors (AGIs), thiazolidinediones (TZD), incretin-dependent therapies, sodium-glucose cotransporter type 2 (SGLT2) inhibitors and combinations thereof. The number of therapeutic alternatives to treat T2DM are increasing and now there are nearly 60 drugs approved by the FDA. Beyond this there are nearly 100 additional antidiabetic agents being evaluated in clinical trials. In addition to the standard treatments of insulin therapy and metformin, there are new drug combinations, e.g., containing metformin, SGLT2 inhibitors and dipeptidyl peptidase-4 (DPP4) inhibitors, that have gained substantial use during the last decade. Furthermore, there are several interesting alternatives, such as lobeglitazone, efpeglenatide and tirzepatide, in ongoing clinical trials. Modern drugs, such as glucagon-like peptide-1 (GLP-1) receptor agonists, DPP4 inhibitors and SGLT2 inhibitors have gained popularity on the pharmaceutical market, while less expensive over the counter alternatives are increasing in developing economies. The large heterogeneity of T2DM is also creating a push towards more personalized and accessible treatments. We describe several interesting alternatives in ongoing clinical trials, which may help to achieve this in the near future.

Cost-Utility of an Online Education Platform and Diabetes Personal Health Record: Analysis Over Ten Years

BACKGROUND AND AIMS

My Diabetes My Way (MDMW) is Scotland's interactive website and mobile app for people with diabetes and their caregivers. It contains multimedia resources for diabetes education and offers access to electronic personal health records. This study aims to assess the cost-utility of MDMW compared with routine diabetes care in people with type 2 diabetes who do not use insulin.

MATERIALS AND METHODS

Analysis used the United Kingdom Prospective Diabetes Study (UKPDS) Outcomes Model 2. Clinical parameters of MDMW users (n = 2576) were compared with a matched cohort of individuals receiving routine care alone (n = 11 628). Matching criteria: age, diabetes duration, sex, and socioeconomic status. Impact on life expectancy, quality-adjusted life years (QALYs), and costs of treatment and complications were simulated over ten years, including a 10% sensitivity analysis.

RESULTS

MDMW cohort: 1670 (64.8%) men; average age 64.3 years; duration of diabetes 5.5 years. 906 (35.2%) women: average age 61.6 years; duration 4.7 years. The cumulative mean QALY (95% CI) gain: 0.054 (0.044-0.062) years. Mean difference in cost: -£118.72 (-£150.16 to -£54.16) over ten years. Increasing MDMW costs (10%): -£50.49 (-£82.24-£14.14). Decreasing MDMW costs (10%): -£186.95 (-£218.53 to -£122.51).

CONCLUSIONS

MDMW is "dominant" over usual care (cost-saving and life improving) in supporting self-management in people with type 2 diabetes not treated with insulin. Wider use may result in significant cost savings through delay or reduction of long-term complications and improved QALYs in Scotland and other countries. MDMW may be among the most cost-effective interventions currently available to support diabetes.

Twenty-year trends in the prescription costs of Type 2 diabetes: Real world data and empirical analysis in Greece

AIMS

To estimate and compare the prescription costs for the management of patients with diabetes over a period of 20 years in Greece, based on real world data.

METHODS

The records of outpatients with T2D, monitored at three diabetes centres, were examined in four cross-sections (1998, 2006, 2012, 2018). Prescribed medicines per patient, along with a set of clinical indicators were recorded. Annual costs of pharmaceutical treatment per patient were calculated by using each year's nominal retail prices, as well as by adjusting for 2018 price levels, in order to account for price differences over time.

RESULTS

4066 patients were included in the analysis. Prescription patterns indicate a quick uptake of the new classes of glucose-lowering drugs and a reduction in the proportional use of sulfonylurea and glitazone. Adjusting for 2018 prices, the average total annual prescription cost per patient was 381.54 Euros (s.d. 297.44) in 1998 and 1147.21 Euros (s.d. 814.39) in 2018. Glucose-lowering drug costs per patient increase from 1998 onwards, whereas the costs of antihypertensive, antiplatelet and lipid-lowering treatment declined gradually, especially after 2006.

CONCLUSIONS

Per patient prescription costs for glucose-lowering drugs present a steep increase, in Greece over the last 20 years. Real-world evidence studies that compare this increase with the changes in patient outcomes are essential in order to examine whether a costs-vs-outcomes balance is optimal.

The Association Between Poor Glycemic Control and Health Care Costs in People With Diabetes: A Population-Based Study

OBJECTIVE

To analyze the differences in health care costs according to glycemic control in people with type 2 diabetes.

RESEARCH DESIGN AND METHODS

Data on health care resource utilization from 100,391 people with type 2 diabetes were extracted from the electronic database used at the Catalan Health Institute. Multivariate regression models were carried out to test the impact of glycemic control (HbA_1c) on total health care, hospital admission, and medication costs; model 1 adjusted for a variety of covariates, and model 2 also included micro- and macrovascular complications. Glycemic control was classified as good for HbA_1c <7%, fair for ≥7% to <8%, poor for ≥8% to <10%, and very poor for ≥10%.

RESULTS

Mean per patient annual direct medical costs were €3,039 ± SD €6,581. Worse glycemic control was associated with higher total health care costs: compared with good glycemic control, health care costs increased by 18% (€509.82) and 23% (€661.35) in patients with very poor and poor glycemic control, respectively, when unadjusted and by €428.3 and €395.1, respectively, in model 2. Medication costs increased by 12% in patients with fair control and by 28% in those with very poor control (model 2). Patients with poor control had a higher probability of hospitalization than those with good control (5% in model 2) and a greater average cost when hospitalization occurred (€811).

CONCLUSIONS

Poor glycemic control was directly related to higher total health care, hospitalization, and medication costs. Preventive strategies and good glycemic control in people with type 2 diabetes could reduce the economic impact associated with this disease.

The Impact of Curcumin on Bone Osteogenic Promotion of MC3T3 Cells under High Glucose Conditions and Enhanced Bone Formation in Diabetic Mice

Diabetic osteoporosis (DOP) is characterized by impaired bone microstructure and reduced bone density resulting from high glucose levels. Curcumin (CURC) is extensively applied in the treatment of inflammation-associated diseases. However, the effect of curcumin on bone metabolism in diabetic osteoporosis is unclear. Therefore, this study investigated the optimal concentration of curcumin on enhancing osteogenesis in diabetic osteoporosis. Osteoblasts were treated with a high or low concentration of curcumin under a series of concentrations of high-glucose conditions. Type 2 diabetic mice were intervened with curcumin. Cell proliferation, apoptosis, and osteogenesis-related gene expressions were evaluated by CCK-8, flow cytometry, and real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR). Bone formation was evaluated by histological staining. The findings revealed that curcumin suppressed apoptosis and enhanced proliferation and osteogenesis-related gene expressions of osteoblasts under high glucose concentrations (p < 0.05). The histological sections displayed reduced bone destruction and increased the growth rate of trabecular bone and the bone density of diabetic mice treated with curcumin, compared to diabetic mice. These results showed that curcumin could reverse the harmful effects of diabetic osteoporosis in a dose-dependent manner, and 10 μmol/L was regarded as the optimal concentration, which supports the potential use of curcumin for bone regeneration under high glucose concentrations.

Drug Prescription Patterns and Cost Analysis of Diabetes Therapy in India: Audit of an Endocrine Practice

AIMS

The aim of this study was to analyze the current trend in the use of antidiabetes as well as other drugs for comorbidities along the duration of diabetes. The study also aimed to analyze the direct drug cost to patients.

SETTINGS AND DESIGN

Retrospective cross-sectional study.

SUBJECTS AND METHODS

Data captured in clinic electronic medical records of an endocrine practice was analyzed.

STATISTICAL ANALYSIS USED

Data was analyzed descriptively using machine learning codes on python platform.

RESULTS

Records of 489 people who attended the clinic during the 6-month period were retrieved. Data of 403 people with diabetes were analyzed after exclusion of incomplete data. Use of antidiabetic drug increased from 1.44 (0.78) [mean (standard deviation)] in people with a duration of diabetes <5 years to 3.18 (1.05) in people with 20+ years of diabetes. The mean number of antidiabetic drug usage seems to plateau at 15 years of diabetes. About 46% of people with 20+ years of diabetes required insulin therapy. Prescription patterns involving a combination of different drug classes in patients were also analyzed. The cost of diabetes therapy increases linearly along the duration of diabetes.

CONCLUSION

This study provides valuable insights on temporal prescription patterns of antidiabetic drugs from an endocrine practice. Metformin remains the most preferred drug across the entire duration of diabetes. Dipeptidyl peptidase-4 inhibitors seem to be fast catching up with sulfonylureas as a second-line treatment after metformin. After 20 years or more of diabetes duration, 46% people would require insulin for glycemic control.
