Burden of Illness in Type 2 Diabetes Mellitus

The Burden of Type 2 Diabetes and the Value of Achieving Near Normoglycemia from the Patient Perspective

INTRODUCTION

Type 2 diabetes (T2D) is extremely burdensome to people with T2D and associated with impaired health-related quality of life. This study explores the impact of T2D and potentially relevant outcomes for new therapies using a unique approach to in-depth qualitative interviews where people with T2D are asked to think about their future with T2D.

METHODS

A cross-sectional qualitative interview study among people with T2D from the USA and UK. Interviews explored their treatment journey, perceptions of their future with T2D, and the value of achieving normoglycemia (explored through presentation of two vignettes with hypothetical medications that reduced hemoglobin A1c [HbA1c] levels < 7% and < 5.7%).

RESULTS

Patients with T2D (N = 50; US n = 25; UK n = 25) were 66.0% male, had a mean body mass index (BMI) of 30.8 ± 6.3 kg/m², and had a mean of 13.0 ± 10.0 years since diagnosis. Current diabetes treatments included diet and exercise only (8.0%), oral medications only (62.0%), oral plus injections (24.0%), and insulin only (6.0%). Despite being treated, participants reported over 25 different unmet needs related to their T2D across a broad range of domains. The most common concerns were diet, diabetes-related complications, weight changes, and psychological and emotional issues. A large majority of participants indicated that achieving lower HbA1c values would change their life. When reflecting on the value of improved glycemic control, patients primarily anticipated physical improvements and improved psychological well-being. When presented with two hypothetical treatments, about 70% of participants preferred the < 5.7% treatment option over the < 7% HbA1c treatment option.

CONCLUSIONS

People with T2D have a high disease burden, a broad range of unmet needs, and extremely varied experiences and expectations on the impacts of T2D on their lives and future. Many patients indicated that achieving near normoglycemia would substantially change their lives primarily in terms of their physical and emotional health.

The Influence of Baseline Hemoglobin A1c on Digital Health Coaching Outcomes in Adults With Type 2 Diabetes: Real-World Retrospective Cohort Study

BACKGROUND

Digital health coaching is an increasingly common diabetes self-management support strategy for individuals with type 2 diabetes and has been linked to positive mental and physical health outcomes. However, the relationship between baseline risk and outcomes is yet to be evaluated in a real-world setting.

OBJECTIVE

The purpose of this real-world study was to evaluate trends in digital health coaching outcomes by baseline hemoglobin A1c (HbA1c) to better understand which populations may experience the greatest clinical and psychosocial benefit.

METHODS

A retrospective cohort study design was used to evaluate program effect in a convenience sample of participants in a 12-week digital health coaching program administered by Pack Health. Participants were referred through their health care provider, payer, or employer. The program included patient-centered lifestyle counseling and psychosocial support delivered via telephone, text, and/or email. Self-reported HbA1c and weight were collected at baseline and completion. Physical and mental health were assessed using the Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health Short Form and the Diabetes Distress Scale-2. Changes in HbA1c, weight, BMI, and physical and mental health were analyzed within three participant cohorts stratified by baseline HbA1c level.

RESULTS

Participants with complete HbA1c data sets (n=226) were included in the analysis. The sample population was 71.7% (162/226) female, with 61.5% (139/226) identifying as white and 34.1% (77/226) as black. Most participants (184/226, 81.4%) reported a baseline HbA1c ≥7%, and 20.3% (46/226) were classified as high risk (HbA1c >9%). Across HbA1c cohorts, the mean baseline BMI was 35.83 (SD 7.79), and the moderate-risk cohort (7% ≤ HbA1c ≤ 9%) reported the highest mean value (36.6, SD 7.79). At 12 weeks, patients reported a significant decrease in HbAlc, and high-risk participants reduced their levels by the greatest margin (2.28 points; P<.001). Across cohorts, BMI improved by 0.82 (P<.001), with the moderate-risk cohort showing the greatest reduction (-0.88; P<.001). Overall, participants reported significant improvements for PROMIS scores, with the greatest change occurring in the high-risk cohort for whom physical health improved 3.84 points (P<.001) and mental health improved 3.3 points (P<.001). However, the lowest-risk cohort showed the greatest improvements in diabetes distress (-0.76; P=.005).

CONCLUSIONS

Acknowledging the limitations in this real-world study design, the results reported here suggest that adults with type 2 diabetes with a high baseline HbA1c or high BMI may benefit the most from patient-centered digital health coaching programs when compared to their lower risk counterparts. While all participants improved in physical and mental health categories, participants with high HbA1c experienced the greatest HbA1c reduction and individuals with the highest baseline BMI lost the most weight. These results may be used to inform referrals for patients who are more likely to benefit from digital health coaching.

Dietary exposures in childhood and adulthood and cardiometabolic outcomes: a systematic scoping review

Associations between diet and cardiometabolic outcomes are often based on a single measurement of diet in adulthood. Dietary exposures in childhood are thought to influence cardiometabolic disease development and individuals' diets can change over time, therefore dietary exposure in childhood and over long periods are both important to consider. This scoping review aimed to identify and characterise the literature on associations between diet measured in both childhood and adulthood and cardiometabolic outcomes. Seven databases were searched; eligible evidence sources were original analyses published as a journal article in English. Exposures included measures of dietary intake, diet quality and eating behaviours measured in both childhood and adulthood with at least five years between first and last measurements. Cardiometabolic outcomes included measures of anthropometry, biochemistry, vascular structure/function and disease states/scores. We identified 37 eligible articles from nine cohort studies. Dietary exposures were measured between two and eight times and most often assessed by food frequency questionnaire or diet history. The dietary exposures most frequently examined were protein, fat, carbohydrate, fruit, vegetables, sugar-sweetened beverages and breakfast. Cardiometabolic outcomes were predominantly based on risk markers. Authors utilised a variety of analytical approaches to transform and analyse repeated measures of diet, providing insights relevant to different lifespan nutrition concepts. The literature on associations between diet in childhood and adulthood and cardiometabolic outcomes is limited, but such studies have great potential to extend our knowledge in ways only possible with repeated measures of diet over time. Further research is needed to develop the evidence base for diet-disease relationships from a life course perspective, accounting for diet in both childhood and adulthood.

Asymptomatic urinary tract infections and associated risk factors in Pakistani Muslim type 2 diabetic patients

Background

One of the leading long-term complications of type 2 diabetes mellitus (T2DM) includes renal dysfunction and urinary tract infections (UTI) which are considered to be prevalent in uncontrolled diabetes. Moreover, physiological factors like age, gender, duration of diabetes, other diabetic complications like neuropathy, autonomic neuropathy and glycosuria are also considered as predisposing factors for increased prevalence of UTI in diabetes which can be symptomatic or asymptomatic.

Methods

This was a cross-sectional, multi-centre study including diabetic patients from 12 clinical sites spread across major cities of Pakistan. The inclusion criteria were adult Pakistani population of age between 18 to 75 years both genders and suffering from T2DM irrespective of duration. A detailed clinical history of the past 3 months was recorded and, biochemical investigations of blood samples were conducted. Urine culture analysis performed identified the type of pathogen present and was done only for asymptomatic patients.

Results

A total of 745 type 2 diabetic patients were initially screened, out of 545 patients considered for final analysis 501 (91.92%) were negative and the rest 44 (8.08%) had positive urine culture. Female gender had a significantly higher proportion of positive urine culture (77.27%, p-value< 0.001). Body mass index and mean age had insignificant distribution among the two groups of positive and negative urine culture, with age 40–59 years having higher proportion (70.45%) in the positive group. Escherichia coli was detected in most of the positive samples (52.3%). All bacterial samples were found resistant to Ciprofloxacin.

Conclusion

Diabetic Pakistani muslim female patients are identified to be at high risk of suffering from asymptomatic UTI and age more than 40 years is an important risk factor. Escherichia coli was the most common causative organism among people living in this geographical area.

Healthcare Costs Associated with Complications in Patients with Type 2 Diabetes among 1.85 Million Adults in Beijing, China

We aimed to provide reliable regression estimates of expenditures associated with various complications in type 2 diabetics in China. In total, 1,859,039 type 2 diabetes patients with complications were obtained from the Beijing Medical Claim Data for Employees database from 2008 to 2016. We estimated costs for complications using a generalized estimating equation model adjusted for age, sex, and the incidence of various complications. The average total cost for diabetic patients with complications was 17.12 thousand RMB. Prescribed drugs accounted for 63.4% of costs. We observed a significant increase in costs in the first year after the onset of complications. Compared with costs before the incidence of complications, the additional costs per person in the first year and >1 year after the event would be 10,631.16 RMB and 1150.71 RMB for cardiovascular disease, 1017.62 RMB and 653.82 RMB for cerebrovascular disease, and 301.14 RMB and 624.00 RMB for kidney disease, respectively. The estimated coefficients for outpatient visits were relatively lower than those of inpatient visits. Complications in diabetics exert a significant impact on total healthcare costs in the first year of their onset and in subsequent years. Our estimates may assist policymakers in quantifying the economic burden of diabetes complications.

Professional continuous glucose monitoring and endocrinology eConsult for adults with type 2 diabetes in primary care: Results of a clinical pilot program

Background

Limitations in access to specialty diabetes care exist. Endocrinology eConsult that integrates professional continuous glucose monitoring (CGM-enhanced eConsult) may improve healthcare delivery, but has yet to be evaluated. We implemented a pilot program for patients with type 2 diabetes (T2DM) managed by primary care clinical pharmacists using CGM-enhanced eConsult and evaluated the acceptability and clinical outcomes in comparison to routine in-person endocrinology consultation.

Methods

Seventy-four adult patients with established T2DM (age 18-65) were included. Twenty-nine were seen in-person by endocrinology and 45 were seen by pharmacists in primary care. Thirteen patients were referred for CGM-enhanced eConsult. Acceptability was assessed with pre/post clinician acceptability questionnaires and patient assessment of perceived burden. Clinical outcomes included time to first specialty appointment, baseline and 3-month follow-up HbA1c, and antihyperglycemic medication use.

Results

There were no differences in patient acceptability of the CGM-enhanced eConsult as compared to endocrinology referral or pharmacy care. At baseline, all patients referred for eConsult were prescribed insulin. Three-month glycemic outcomes were comparable, with HbA1c reduction 1% + 2% in endocrinology, 1.5% + 1.1% with CGM-enhanced eConsult, and 1.6% + 1.8% in clinical pharmacy (p = 0.19). Time to an initial diabetes visit with a pharmacist was significantly shorter than with endocrinology, 20 days (IQR 26) for pharmacy vs. 45 days (IQR 54) for endocrinology, (p = 0.0001).

Conclusions

CGM-enhanced eConsult resulted in more timely access to endocrinology expertise, was acceptable to patients, and resulted in similar short-term glycemic outcomes compared to in-person consultation. Effectiveness of CGM-enhanced eConsults should be further explored.

Economic burden of diabetes among medicare beneficiaries with cancer

Objectives

Older adults are commonly affected by cancer and diabetes, and an investigation of the economic burden faced by these older adults remains a research gap. Therefore, the objective was to assess the economic burden of diabetes among Medicare beneficiaries with cancer by analyzing annual costs from administrative claims data.

Methods

We conducted a retrospective, serial cross-sectional study using the Medicare Current Beneficiary Survey (MCBS) from 2006 to 2012. Eligible beneficiaries must be currently or previously diagnosed with cancer (of any type), ≥65 years of age, non-institutionalized and continuously enrolled annually in Medicare Parts A, B and D. Diagnoses of cancer and diabetes were determined through self-report or claims. The primary outcome was the total economic burden of diabetes per capita annually, operationalized as the difference in total direct costs between cancer patients with and without diabetes. Simple linear regression was used to analyze trends of costs across the years. Multivariable regression estimated the effect of diabetes and covariates on total annual spending among beneficiaries with cancer from 2006-2012.

Key findings

From 2006 to 2012, 4918 beneficiaries included in MCBS had cancer, with over 25% (1275) also having diabetes. From 2006 to 2012, the mean economic burden of diabetes was $7815 per capita annually. After adjusting for covariates, beginning in 2006, diagnosis of diabetes significantly predicted higher total annual spending among cancer beneficiaries in 2007 [coefficient (SE) = 0.5768 (0.1918), P = 0.003], 2011 [coefficient (SE) = 0.4303 (0.1817), P = 0.018] and 2012 [coefficient (SE) = 0.3605 (0.1758), P = 0.040].

Conclusions

Medicare beneficiaries with cancer experienced a higher economic burden from concurrent diabetes.

Quantifying the Influence of Individual, Community, and Health System Factors on Quality of Life Among Inner-City African Americans With Type 2 Diabetes

PURPOSE

The purpose of this study is to examine the association of individual, community, and health system factors on quality of life among inner-city African Americans with type 2 diabetes.

METHODS

Primary data from a cross-sectional study with a community sample of 241 inner-city African Americans with type 2 diabetes were analyzed. Paper-based surveys were administered in which the SF-12 was used to capture the physical component (PCS) and mental component (MCS) of quality of life. Four regression approaches (sequential, stepwise with backward and forward selection, and all possible subsets regression) were used to examine the influence of individual, community, and health system factors on PCS and MCS after adjusting for relevant covariates using a conceptual framework.

RESULTS

In fully adjusted models, having less than a high school education and having major depression were associated with lower quality-of-life scores for MCS across all 4 regression approaches. Being employed was positively associated with better quality-of-life scores for PCS across all 4 regression approaches. PCS was higher across all 4 regression approaches for those reporting a history of trauma. At the health systems level, usual source of care was associated with better PCS across 3 regression approaches.

CONCLUSIONS

These results highlight key factors that influence quality of life among inner-city African Americans with type 2 diabetes that could be targets for interventions in this population. However, additional research is needed to understand existing pathways that may be driving many of these relationships.

Flash CGM Is Associated With Reduced Diabetes Events and Hospitalizations in Insulin-Treated Type 2 Diabetes

Purpose

Suboptimal glycemic control among individuals with diabetes is a leading cause of hospitalizations and emergency department utilization. Use of flash continuous glucose monitoring (flash CGM) improves glycemic control in type 1 and type 2 diabetes, which may result in lower risk for acute and chronic complications that require emergency services and/or hospitalizations.

Methods

In this retrospective, real-world study, we analyzed IBM MarketScan Commercial Claims and Medicare Supplemental databases to assess the impact of flash CGM on diabetes-related events and hospitalizations in a cohort of 2463 individuals with type 2 diabetes who were on short- or rapid-acting insulin therapy. Outcomes were changes in acute diabetes-related events (ADE) and all-cause inpatient hospitalizations (ACH), occurring during the first 6 months after acquiring the flash CGM system compared with event rates during the 6 months prior to system acquisition. ICD-10 codes were used to identify ADE for hypoglycemia, hypoglycemic coma, hyperglycemia, diabetic ketoacidosis, and hyperosmolarity.

Results

ADE rates decreased from 0.180 to 0.072 events/patient-year (hazard ratio [HR]: 0.39 [0.30, 0.51]; P < 0.001) and ACH rates decreased from 0.420 to 0.283 events/patient-year (HR: 0.68 [0.59 0.78]; P < 0.001). ADE reduction occurred regardless of age or gender.

Conclusions

Acquisition of the flash CGM system was associated with reductions in ADE and ACH. These findings provide support for the use of flash CGM in type 2 diabetes patients treated with short- or rapid-acting insulin therapy to improve clinical outcomes and potentially reduce costs.

Association Between Systemic Immune-Inflammation Index and Diabetic Depression

Background

Depression is highly prevalent in patients with diabetes mellitus (DM). Diabetic depression has been shown to be associated with low-grade systemic inflammation. In recent years, the systemic immune-inflammation (SII) index has been developed as an integrated and novel inflammatory indicator. The aims of this study were to investigate the relationship between diabetic depression and SII levels, adjusting for a wide range of potential confounding factors, to examine the potential of SII in predicting diabetic depression.

Methods

The present cross-sectional study was conducted among adults with DM in the National Health and Nutrition Examination Survey between 2009 and 2016, the SII level was calculated as the platelet counts × neutrophil counts/lymphocyte counts. Patient Health Questionnaire‐9 was used to measure depression in patients with DM. Multivariable logistic regression and propensity score-matched analysis were used to analyze the association between SII levels and depression.

Results

A total of 2566 patients with DM were included in the study, of which 370 (13.3%) were diagnosed with depression. Multivariable logistic regression showed that high SII level was an independent risk factor for diabetic depression (OR = 1.347, 95% CI: 1.031–1.760, P = 0.02882) after adjusting for covariates. The relationship between SII and diabetic depression was further verified by propensity score-matched analysis.

Conclusion

Our data suggest that SII is a risk factor for depression in patients with DM. The SII may be an easily accessible and cost-effective strategy for identifying depression in patients with DM. More studies are warranted to further analyze the role of SII in depression in diabetic patients.

Interactive associations of the INAFM2 rs67839313 variant and egg consumption with type 2 diabetes mellitus and fasting blood glucose in a Chinese population: A family-based study

BACKGROUND

INAFM2 rs67839313 was associated with type 2 diabetes (T2DM) in Japanese populations but not in other populations. We aimed to validate the association of rs67839313 with T2DM and explore interactive associations of INAFM2 rs67839313 and egg consumption with T2DM and fasting blood glucose (FBG) in a Chinese population.

METHODS

In total, 7175 participants (4202 T2DM cases) from 3980 families were included and categorized into two groups (<4 and ≥4 eggs/week) according to the median egg consumption. Multilevel logistic regression and linear regression models were performed to estimate the genetic associations of rs67839313 with T2DM and FBG, respectively. The crossproduct term between the variant and egg was included in the models for interaction analysis.

RESULTS

We found that rs67839313_T was associated with an increased risk of T2DM (1.22 [95% CI: 1.17-1.27], P < 0.001). Among individuals with the rs67839313_T genotype, those with egg consumption <4/week (1.37 [1.25-1.51]) had a higher T2DM risk than those with egg consumption ≥4/week (1.17 [1.11-1.23]). A significant interactive effect between rs67839313_T and egg consumption on T2DM risk was identified (P = 0.008). Moreover, among participants without T2DM, rs67839313_T was associated with FBG, with a 0.188 mmol/l increase and a 0.152 mmol/l decrease among those consuming <4 eggs/week and ≥4 eggs/week, respectively. The interaction between rs67839313_T and egg consumption was observed to be significantly associated with FBG (P = 0.003).

CONCLUSIONS

INAFM2 rs67839313_T was associated with increased T2DM risk and FBG levels in Chinese individuals, and consuming more eggs may eliminate the associated genetic risk. This finding has important implications for understanding the genetic pathogenesis of T2DM and for the precision nutrition management of T2DM.

Insulin glargine 300 U/mL versus first-generation basal insulin analogues in insulin-naïve adults with type 2 diabetes: 12-month outcomes of ACHIEVE Control, a prospective, randomized, pragmatic real-life clinical trial

AIM

To report the effectiveness and safety of insulin glargine 300 U/mL (Gla-300) versus standard-of-care basal insulin analogues (SOC-BI) at 12 months in the ACHIEVE Control trial, which is a prospective pragmatic randomized real-life study in insulin-naïve adults with type 2 diabetes (T2D).

METHODS

A total of 3304 insulin-naïve adults with T2D and glycated haemoglobin (HbA1c) concentration of 64 to 97 mmol/mol (8.0% to 11.0%) after ≥1 year of treatment with two or more antihyperglycaemic agents were randomized to Gla-300 or SOC-BI. Key secondary endpoints included HbA1c target attainment without documented symptomatic (≤3.9 mmol/L [≤70 mg/dL]) or severe hypoglycaemia at 12 months.

RESULTS

At 12 months, 26.1% (Gla-300) and 23.7% (SOC-BI) of adults achieved HbA1c targets without documented symptomatic (≤3.9 mmol/L [≤70 mg/dL]) or severe hypoglycaemia (odds ratio [OR] 1.14, 95% confidence interval [CI] 0.97-1.35); 33.0% and 29.5%, respectively, achieved HbA1c targets without documented symptomatic (<3.0 mmol/L [<54 mg/dL]) or severe hypoglycaemia (OR 1.19, 95% CI 1.02-1.38). The OR for HbA1c target achievement was 1.15 (95% CI 0.99-1.34), and favoured Gla-300 versus SOC-BI for absence of documented symptomatic or severe hypoglycaemia at 12 months for both ≤3.9 mmol/L (≤70 mg/dL; OR 1.21, 95% CI 1.05-1.40) and < 3.0 mmol/L (<54 mg/dL; OR 1.26, 95% CI 1.07-1.48).

CONCLUSION

Gla-300 tended to be associated with lower hypoglycaemia risk than SOC-BI in real-world clinical practice during the 12-month follow-up.

Patient preferences for treatment of advanced melanoma: impact of comorbidities

BACKGROUND AND OBJECTIVES

Choice of treatment for advanced melanoma is crucially influenced by comorbidities and patient preferences. Our study aimed to investigate the impact of comorbidities on preferences.

PATIENTS AND METHODS

150 patients with melanoma stage IIC-IV completed a discrete choice experiment to determine preferences for outcome (overall response rate [ORR], 2-year survival, progression-free survival [PFS], time to response [TTR], kind of adverse events [AE], AE-related treatment discontinuation) and process attributes (frequency and route of administration [RoA], frequency of consultations) of systemic melanoma treatments. The impact of comorbidities was assessed by analysis of variance and multivariate regression.

RESULTS

Participants with hypertension and other cardiovascular diseases attached significantly greater importance to TTR and RoA than others. Respondents with arthropathy cared more about TTR (β = 0.179, P = 0.047) and RoA, but less about ORR (β = -0.209, P =  0.021). Individuals with diabetes considered AE (β = 0.185, P = 0.039) and frequency of consultations more essential, but ORR less relevant. Those with other malignancies were particularly worried about treatment discontinuation (β = 0.219, P =  0.008), but less about ORR (β = -0.202, P =  0.015). Participants with depression focused more on PFS (β = 0.201, P =  0.025) and less on TTR (β = -0.201, P =  0.023) and RoA (β = -0.167, P =  0.050).

CONCLUSIONS

Treatment preferences of melanoma patients vary significantly dependent on comorbidities.

Effects of TNF-α-308G/A Polymorphism on the Risk of Diabetic Nephropathy and Diabetic Retinopathy: An Updated Meta-Analysis

Diabetic nephropathy (DN) and diabetic retinopathy (DR) are the major factors of morbidity and mortality in the patients with diabetes mellitus (DM). Growing studies have investigated the relationship between the TNF-α-308G/A polymorphism and the susceptibility to DN and DR, without achieving consensus. Thus, we conducted this meta-analysis to reach more comprehensive conclusions for these issues. Eligible studies were retrieved through electronic databases such as PubMed, Embase, Web of Science and China National Knowledge Infrastructure. Summary of odds ratios (OR) and 95% confidence intervals (CIs) were generated to evaluate the intensity of the associations. Statistical analyses were performed by STATA 11.0 and RevMan 5.2. There are fourteen eligible publications involving nineteen studies in this meta-analysis. TNF-α-308G/A polymorphism was significantly related to increasing risk of DN under recessive model (OR=1.37, 95% CI=1.03-1.83) and homozygous model (OR=1.54, 95% CI=1.15-2.06). Moreover, the similar results were also obtained in Asian groups for DN (recessive: OR=1.69, 95% CI=1.18-2.42; homozygous: OR=1.99, 95% CI=1.38-2.86; respectively), and significant association was also detected between TNF-α-308G/A and DN susceptibility in type 2 DM in recessive model (OR=1.39, 95% CI=1.02-1.89). No significant association was observed between TNF-α-308G/A and DR susceptibility in total analyses and subgroup analyses by ethnicity and type of DM. TNF-α-308G/A polymorphism may enhance the susceptibility to diabetic nephropathy, especially in Asian population and in T2DM patients, but not diabetic retinopathy.

Long-Term Cost-Effectiveness Analyses of Empagliflozin Versus Oral Semaglutide, in Addition to Metformin, for the Treatment of Type 2 Diabetes in the UK

INTRODUCTION

International guidelines recommend treatment with a sodium-glucose cotransporter-2 (SGLT-2) inhibitor or glucagon-like peptide-1 (GLP-1) receptor agonist for treatment intensification in type 2 diabetes mellitus (T2DM) patients with progression on metformin. In the randomised, controlled, Peptide Innovation for Early Diabetes Treatment (PIONEER) 2 trial, the SGLT-2 inhibitor empagliflozin was compared with the GLP-1 receptor agonist oral semaglutide, in addition to metformin. The aim of the current study was to assess the long-term cost-effectiveness of empagliflozin 25 mg versus oral semaglutide 14 mg, in addition to metformin, for T2DM patients in the UK.

METHODS

Analyses were conducted from the UK healthcare payer perspective, using the IQVIA Core Diabetes model, with a time horizon of 50 years. Patients received either empagliflozin or oral semaglutide, in addition to metformin, until Hba1c threshold of 7.5% (58 mmol/mol) was exceeded, following which treatment intensification with insulin glargine in addition to empagliflozin or oral semaglutide plus metformin was assumed. Baseline cohort characteristics and 52-week treatment effects were derived from the PIONEER 2 trial. Treatment effects of empagliflozin and GLP-1 receptor agonists on hospitalisation for heart failure (hHF) were based on the Empagliflozin Comparative Effectiveness and Safety (EMPRISE) real-world study. Utilities, treatment costs and costs of diabetes-related complications were obtained from published sources.

RESULTS

Direct costs for empagliflozin plus metformin were considerably lower than those for oral semaglutide plus metformin (by more than GBP 6000). Compared with oral semaglutide plus metformin, empagliflozin plus metformin was a cost-effective treatment for T2DM patients in all scenarios tested. Probabilistic sensitivity analysis showed cost-effectiveness in > 95% of the iterations using a threshold of 20,000 GBP/QALY.

CONCLUSION

Empagliflozin 25 mg is a cost-effective treatment option versus oral semaglutide 14 mg, when used in addition to metformin, for the treatment of T2DM patients in the UK.

Safety and tolerability of once-weekly GLP-1 receptor agonists in type 2 diabetes

WHAT IS KNOWN AND OBJECTIVE

In recent years, glucagon-like peptide-1 receptor agonists (GLP-1 RAs) including once-weekly (QW) formulations have been incorporated into type 2 diabetes (T2D) clinical guidelines, making it essential that pharmacists and healthcare professionals (HCPs) have a clear understanding of their safety profiles. Currently, three QW GLP-1 RAs are approved and marketed in the United States for the treatment of T2D: dulaglutide, exenatide extended-release and semaglutide. This review provides pharmacists and HCPs with collated data related to potential safety and tolerability issues when patients use QW GLP-1 RAs, enabling patient education and treatment optimization.

METHODS

This is a narrative review comparing the safety and tolerability of the three QW GLP-1 RAs, using data from Phase 3 clinical trials. Extracted safety data included gastrointestinal (GI) adverse events (AEs), hypoglycaemia, injection-site reactions, pancreatitis, neoplasms, gallbladder events, and diabetic retinopathy (DR) and/or its complications (DRCs).

RESULTS AND DISCUSSION

A total of 30 trials were identified for inclusion; eight were head-to-head trials involving another GLP-1 RA; of these, six compared GLP-1 RAs with different dosing regimens (QW vs once-daily or twice-daily), and two were direct QW vs QW GLP-1 RA comparisons. The most commonly reported AEs were GI events (notably nausea, vomiting and diarrhoea), but there was variation between the three QW drugs. These were generally mild-to-moderate in severity and transient. Risk of hypoglycaemia, injection-site reactions, pancreatitis, neoplasms and gallbladder events was generally low across the GLP-1 RAs investigated. Overall rates of DR or DRC were low across the trials. Only in one trial (SUSTAIN 6) there were significantly more DRC events reported in patients treated with QW semaglutide (3.0%) compared with placebo (1.8%). This was likely due to the rapid improvement in glucose control in patients with pre-existing DR enrolled within that trial.

WHAT IS NEW AND CONCLUSION

This review puts the latest clinical data from the marketed QW GLP-1 RAs into context with results from older Phase 3 trials, to enable pharmacists and HCPs to make informed treatment decisions. Each of the three QW GLP-1 RAs has their own safety profile, which should be considered when choosing the optimal treatment for patients.

Severe diabetes complications among patients with diabetes with regular follow-up: Does care setting matter?

OBJECTIVE

To investigate diabetes outcomes by long-term trajectories of patients' care settings among diabetes patients with regular follow-up.

RESEARCH DESIGN AND METHODS

This longitudinal population-based cohort study used data from the National Health Insurance Research Database in Taiwan. The trajectories of diabetes care-seeking behaviours among newly diagnosed diabetes patients with regular follow-up were identified using a group-based trajectory model from 2000 to 2004. Severe diabetes complications were assessed for the period 2005-2010. Cox-proportional hazard method with a cumulative incidence function was applied.

RESULTS

Among the diabetes patients with regular follow-up during the first 5 years since diagnosis, 44.5% and 40.6% were persistently cared for in generalized care settings and specialized settings, respectively. Only 14.9% of them had shifted between different levels of care setting during the first 5 years. No significant difference in adverse outcomes was observed between patients who were persistently treated in generalized and specialized care settings. Significantly worse outcomes were observed among patients who shifted from generalized care settings to specialized settings (adjusted hazard ratio [aHR]=3.2, 95% confidence interval [CI]: 1.5, 6.8). In contrast, among the elderly, regular users of generalized care providers had a higher hazard of adverse outcomes than those of specialized care providers (aHR = 3.3, 95% CI: 1.0, 10.7).

CONCLUSIONS

Diabetes patients who were persistently treated in generalized care settings had health outcomes comparable to those who were persistently treated in specialized care settings. However, for elderly and less stable patients, regular diabetes care in specialized care settings was preferable.

Depression in the Peruvian population and its associated factors: analysis of a national health survey

BACKGROUND

To date, the factors associated with the presence of depression or depressive symptoms in the Peruvian population have not been described. This study aimed to determine the prevalence of clinically relevant depressive symptoms in the Peruvian population and its associated factors.

METHODS

A cross-sectional analytical study of secondary data from 2018 Demographic and Family Health Survey was conducted. The survey database includes 31,996 participants over 18 years of age. The dependent variable of the analysis was the presence of depression during the 14 days before the survey measured by the Patient Health Questionnaire (PHQ-9). Factors associated with the presence of depression were estimated with a proportional odds logistic regression model.

RESULTS

The overall prevalence of clinically relevant depressive symptoms was 6.4% (moderate and severe symptomatology in 3.9% [95% CI: 3.6-4.3] and 2.5% [95% CI: 2.2-2.7], respectively). Being a woman, belonging to the age groups of 45 to 64 years or 65 or older, living in the Andean region, and having high blood pressure or diabetes mellitus or some disability increased the probability of having clinically relevant depressive symptoms.

LIMITATIONS

The use of the PHQ-9 tool to assess depressive symptomatology limits the evaluation to a period of two weeks before the survey, requiring further study for diagnosis confirmation.

CONCLUSION

Six out of 100 Peruvians presented moderate to severe clinically relevant depressive symptoms in 2018. Strategies for depression should contemplate population subgroups , such as women and patients with chronic diseases and disabilities.

Disease Burden and Healthcare Costs for T2D Patients With and Without Established Cardiovascular Disease in Sweden: A Retrospective Cohort Study

INTRODUCTION

Type 2 diabetes (T2D) is a complex chronic disease with an increasing prevalence worldwide. It is commonly associated with complications, such as cardiovascular disease (CVD). Patients with both T2D and established CVD are exposed to increased risk of further cardiovascular events, which means increased healthcare costs and impairments to quality of life and survival. To determine the added burden of CVD for T2D patients, we have analyzed the consumption and costs of healthcare and mortality in two T2D patient cohorts, with and without established CVD, respectively, during a 5-year follow-up in a Swedish region.

METHODS

Patients with T2D on 1 January 2012 were identified using the administrative database of Region Östergötland and the Swedish National Diabetes Register. Established CVD was defined as the presence of a CVD-related healthcare visit in the period 2002-2011. Identified T2D patients were then followed retrospectively for 5 years (2012-2016) and data collected on utilization of healthcare resources, healthcare costs, and survival. Data pertinent to the study were retrieved from regional databases and national registries.

RESULTS

On the index date (1 January 2012) there were 19,731 patients with T2D (prevalence 4.5%) in Region Östergötland, of whom 5490 had established CVD. Those patients with established CVD were older, more often men, and had longer diabetes duration and worse kidney function than those without. Compared to T2D patients without CVD, those with CVD had a significantly higher healthcare consumption, experienced higher costs, and had lower survival during the follow-up.

CONCLUSION

This study confirms that established CVD is common among patients with T2D (approximately 30%). Established CVD has negative effects on the utilization of healthcare resources, healthcare costs, and mortality. It is therefore very important to improve the treatment strategy of this patient group.

The fat mass, estimated glomerular filtration rate, and chronic inflammation in type 2 diabetic patients

BACKGROUND

The aim of the study was to analyze the degree of obesity and its associations with age, gender, inflammation, an estimated glomerular filtration rate (eGFR), and liver function in type 2 diabetes mellitus (T2DM) patients.

METHODS

A total of 874 consecutive adult Caucasian T2DM patients from outpatient diabetic clinic were included in the study. The relative fat mass (RFM) and body mass index (BMI) were used as obesity markers. Serum creatinine and cystatin C were used for the GFR estimation. Serum high-sensitive C-reactive protein (hsCRP) was used as the indicator of inflammation.

RESULTS

The median, interquartile range (IQR) of RFM in females was higher than that in males (44.8 (42.3-47.2) % vs 31.3 (28.8-34.1) %, respectively; P < .0001). The median (IQR) of BMI in females was no higher than that in males (30 (27-34) kg/m2 vs 30 (27-34), respectively; P = .5152). The obesity prevalence was 99% in males and 98% in females according to RFM. BMI recognized obesity in 51% males and 53% females. RFM was positively associated with hsCRP in both males (rs  = .296, P < .0001) and females (rs  = .445, P < .0001). ALT was positively correlated with eGFRcys in both males (rs  = .379, P < .0001) and females (rs  = .308, P < .0001).

CONCLUSION

The RFM equation leads to higher obesity prevalence compared to BMI. Women have higher RFM compared to men. The kidney function was positively correlated with ALT serum concentrations.

Effectiveness and safety of insulin glargine 300 U/mL in insulin-naïve patients with type 2 diabetes after failure of oral therapy in a real-world setting

AIM

To evaluate the effectiveness and safety of initiating basal insulin-supported oral therapy (BOT) with insulin glargine 300 U/mL (Gla-300) in patients with type 2 diabetes inadequately controlled on oral antidiabetic drugs (OADs).

MATERIALS AND METHODS

This non-interventional, multi-centre, prospective 52-week study, conducted in Germany and Switzerland, documented patients with type 2 diabetes with an HbA1c of between 7.5% and 10.0%, currently treated with OADs, after the physician had decided to start a BOT regimen with Gla-300. The primary endpoint was the rate of achievement of the individualized predefined HbA1c target.

RESULTS

Of 1748 patients included, 1153 comprised the full analysis set, of whom 721 completed documentation of 12 months of Gla-300 treatment. Twelve months after starting Gla-300, 49.9% achieved their individualized HbA1c target, and 61.1% achieved either their HbA1c target or a fasting plasma glucose (FPG) of ≤110 mg/dL. Mean HbA1c decreased by -1.22% ± 1.05% to 7.28% ± 0.92% and mean FPG by -51.5 (±48.63) mg/dl to 132.9 ± 33.0 mg/dL. Median duration of HbA1c target achievement was 341 days and probability to remain on target after 6 months was 81%. Hypoglycaemia incidence and rates remained low after 12 months of Gla-300 treatment; no severe or severe nocturnal hypoglycaemia was observed. Body weight remained unchanged.

CONCLUSIONS

Starting a BOT regimen with Gla-300 allowed about 60% of 721 German and Swiss patients with inadequately controlled type 2 diabetes to achieve glycaemic control within 12 months in daily clinical practice. Glycaemic control was achieved without weight gain or increased risk of nocturnal or severe hypoglycaemia.

P2X7 receptor mediates NLRP3 inflammasome activation in depression and diabetes

The increasing prevalence of depression and diabetes mellitus has become a major public health problem worldwide. Studies have shown that people with diabetes are at a high risk of being diagnosed with depression, and diabetes complicates depression treatment by promoting the deterioration of glycemic control, reducing self-care ability and quality of life, and causing severe functional disability and early mortality. Moreover, health deterioration dramatically increases the financial cost of social and health care system. Thus, how to treat depression, diabetes, and diabetes complicated by depression has become one of the world’s urgent concerns. The activation of nod-like receptor family pyrin domain containing 3 (NLRP3) is closely related to mental illness. This finding provides a new perspective for studying depression. NLRP3 plays an important role in the development of diabetes. In this review, we elaborate the definition and epidemiology of depression, diabetes, and diabetic depression and introduce the functional characteristics of an NLRP3 inflammasome and upstream P2X7 receptor. Moreover, related research on NLRP3 inflammasomes and P2X7 receptors is summarized and used as a reference for confirming that the excessive activation of P2X7- NLRP3 leads to the increased release of inflammatory cytokines, such as IL-1β, in depression and diabetes. We provide insights into the P2X7–NLRP3–IL-1β pathway as an important pathological mechanism and novel therapeutic target in diabetes and depression. Given that the P2X7–NLRP3–IL-1β pathway may play an important role in diabetes confounded by comorbid depression, the possibility of intervention with baicalin is proposed.

Pleiotropic Effects of a KCNQ1 Variant on Lipid Profiles and Type 2 Diabetes: A Family-Based Study in China

OBJECTIVE

The genetic variant rs2237895, located in the Potassium Voltage-Gated Channel Subfamily Q Member 1 (KCNQ1) gene, has been replicated to be associated with type 2 diabetes mellitus (T2DM) susceptibility, but the relationship with lipids is conflicting. Furthermore, the common genetic predisposition to T2DM and lipids was not fully detected.

METHODS

In total, 5839 individuals (2220 were T2DM patients) across 2885 families were included. The effect of rs2237895 on T2DM and lipids was estimated using linear regression and logistic regression models after adjustment for multiple covariates. Mediation analysis was then used to test whether KCNQ1 participated in T2DM pathogenesis via lipid-mediated pathways.

RESULTS

Per allele-C of rs2237895 was associated with 17% (11-23%, P < 0.001) increased T2DM risk. Moreover, it was correlated with 5% (1-9%, P < 0.001) increased T2DM risk. Moreover, it was correlated with 5% (1-9%, P < 0.001) increased T2DM risk. Moreover, it was correlated with 5% (1-9%, P < 0.001) increased T2DM risk. Moreover, it was correlated with 5% (1-9%, P < 0.001) increased T2DM risk. Moreover, it was correlated with 5% (1-9%, P < 0.001) increased T2DM risk. Moreover, it was correlated with 5% (1-9%.

CONCLUSION

KCNQ1 had pleiotropic effects on lipids and T2DM, and the unexpected genetic effect on association of HDL-C with T2DM was observed, indicating the different pathways to lipids and T2DM. Further research studies are needed to verify potential biological mechanisms.

Noncoding RNAs in Diabetic Nephropathy: Pathogenesis, Biomarkers, and Therapy

The correlation between diabetes and systematic well-being on human life has long established. As a common complication of diabetes, the prevalence of diabetic nephropathy (DN) has been increasing globally. DN is known to be a major cause of end-stage kidney disease (ESKD). Till now, the molecular mechanisms for DN have not been fully explored and the effective therapies are still lacking. Noncoding RNAs are a class of RNAs produced by genome transcription that cannot be translated into proteins. It has been documented that ncRNAs participate in the pathogenesis of DN by regulating inflammation, apoptosis, autophagy, cell proliferation, and other pathological processes. In this review, the pathological roles and diagnostic and therapeutic potential of three types of ncRNAs (microRNA, long noncoding RNA, and circular RNA) in the progression of DN are summarized and illustrated.

Do Probiotics Improve the Health Status of Individuals with Diabetes Mellitus? A Review on Outcomes of Clinical Trials

Probiotics are now considered as an adjuvant and complementary therapeutic agent for several health complications, especially for metabolic and gastrointestinal disorders because of the influential impact of probiotic consumption on gut microbiota and immunity. Diabetes mellitus (DM) is fourth, in noncommunicable disease category, leading cause of mortality, morbidity, and economic crises in the world. Though several progressions are added in the medical field in recent decades, the treatment and management of diabetic-related health issues are still challenging. The present study summarizes the effects of probiotic supplementation on the health status of diabetic patients. The relevant information was collected from Scopus, PubMed, and Google Scholar. The detailed literature survey revealed that the consumption of probiotic supplementation significantly improved the overall health condition of diabetic patients. Especially, the probiotic intervention improved the fasting blood glucose, insulin sensitivity, and systemic inflammatory and antioxidant status in type 2 diabetic (T2D) patients. Moreover, improvement of gut microbial composition and prevention of bacterial translocation has also been observed in probiotic-supplemented T2D people. Some of the studies evidenced that the supplementation of probiotics can prevent and improve the gestational DM. Nevertheless, some of the studies reported negative results and limitations in the results of clinical trials. However, further studies are mandatory to develop a concrete probiotic-based adjuvant treatment procedure to treat DM.

Effect of Konjac Mannan Oligosaccharides on Glucose Homeostasis via the Improvement of Insulin and Leptin Resistance In Vitro and In Vivo

Functional oligosaccharides, particularly konjac mannan oligosaccharides (KMOS), can regulate glucose metabolism. However, the molecular mechanisms involved in the hypoglycemic effect of KMOS remain largely unknown. Here, the effect of KMOS supplementation on glucose homeostasis was evaluated in both high-fat diet (HFD)-fed C57BL/6J mice and high-glucosamine-induced HepG2 cells. KMOS supplementation remarkably ameliorated the fasting blood glucose, glucose tolerance, and insulin tolerance of HFD-fed mice. Abnormalities of triglyceride and glycogen metabolism in the liver induced by the HFD were reversed by KMOS supplementation. The insulin signaling pathway was activated by KMOS, with stimulation of GLUT2 membrane translocation and glucose uptake in HepG2 cells via the AMPK pathway. Moreover, KMOS suppressed p-mTOR expression and stimulated the GSK-3β/CREB pathway via the AMPK pathway. KMOS significantly upregulated leptin receptor expression and downregulated PTP1B and SOCS3 levels in the liver and brain, with a decreased serum leptin concentration. Phosphorylation of JAK2 and STAT3 in the liver was activated by KMOS supplementation, while the expressions of Sirt1, Tfam, and Pgc1-α in the brain were elevated. Conclusively, KMOS attenuated HFD-induced glucose metabolism dysfunction through the regulation of insulin resistance and leptin resistance. This finding indicates that KMOS have potential value as an anti-hyperglycemic dietary supplement.
