Effects of SGLT2 inhibitors on the onset of esophageal varices and extrahepatic cancer in type 2 diabetic patients with suspected MASLD: a nationwide database study in Japan

BACKGROUND & AIM

SGLT2 inhibitors (SGLT2i) improve hepatic steatosis in patients with type 2 diabetes mellitus (T2DM) and MASLD. We aimed to investigate the impact of SGLT2i on the incidence of liver-related events and extrahepatic cancer compared to DPP4 inhibitors (DPP4i) in patients with T2DM and suspected MASLD using a medical claims database in Japan.

METHODS

We conducted a retrospective study using a Japanese medical claims database. Among patients with T2DM who were prescribed SGLT2i or DPP4i (n = 1,628,656), patients with suspected MASLD were classified into SGLT2i (n = 4204) and DPP4i (n = 4204) groups. Effects of SGLT2i on the following outcomes were compared to DPP4i: (1) changes in HbA1c and ALT levels after 6 months, (2) changes in hepatic fibrosis index, and (3) the incidence of liver-related events/extrahepatic cancer over 12 months.

RESULTS

After 6 months, DPP4i significantly decreased HbA1c levels compared to SGLT2i. In contrast, SGLT2i significantly decreased ALT levels compared to DPP4i. SGLT2i significantly decreased FIB-4 index compared to DPP4i over 12 months. Although no significant difference was observed in the incidence of overall liver-related events between the two groups, SGLT2i significantly reduced the incidence of esophageal varices (HR 0.12, 95%CI 0.01-0.95, P = 0.044). Moreover, SGLT2i significantly suppressed the incidence of extrahepatic cancer (HR 0.50, 95%CI 0.30-0.84, P = 0.009) compared to DPP4i.

CONCLUSION

SGLT2i was more beneficial than DPP4i in improving the hepatic inflammation and fibrosis indices. Moreover, SGLT2i suppressed the incidence of esophageal varices and extrahepatic cancer compared to DPP4i. SGLT2i may suppress life-threatening events in patients with T2DM and suspected MASLD.

Assessing Current Knowledge of Hearing Impairment With Diabetes by Surveying Providers With CBDCE Certification

PURPOSE

The purpose of this study was to assess current knowledge, attitudes, and practices regarding hearing impairment and screening referrals in patients with diabetes among providers who have a Certified Diabetes Care and Education Specialist (CBDCE) Certification.

METHODS

A cross-sectional survey created through Qualtrics was emailed to health care providers in the United States with CDCES certification. Providers responded regarding knowledge and importance of hearing impairment compared to other diabetes complications, when they would refer a patient to an audiologist, the percentage of patients referred, and awareness of over-the-counter hearing aids. Descriptive statistics were calculated for all questionnaire items.

RESULTS

One thousand four hundred and ninety-five CDCES providers completed the survey. Participants selected the most common conditions associated with diabetes as kidney dysfunction (96.7%), retinopathy (96.5%), obesity (95.6%), and foot infection (94.5%); 44.5% chose hearing impairment. Over 60% of providers were not familiar with how to refer patients to an audiologist and acknowledged being unfamiliar with recommended screening frequency as the most common barrier. Most providers had referred fewer than 20% of patients to an audiologist. Over half of providers were not aware of over-the-counter hearing aids.

CONCLUSION

Among a national sample of health care providers with comprehensive knowledge in diabetes care, many providers do not associate hearing impairment with diabetes and rate other microvascular complications of higher importance.

Synergistic association of sodium-glucose cotransporter-2 inhibitor and metformin on liver and non-liver complications in patients with type 2 diabetes mellitus and metabolic dysfunction-associated steatotic liver disease

OBJECTIVE

Type 2 diabetes mellitus and metabolic dysfunction-associated steatotic liver disease (diabetic MASLD) frequently coexist and worsen liver and non-liver outcomes, but effective pharmacological therapies are limited. We aimed to evaluate the long-term effect of sodium-glucose cotransporter-2 inhibitor (SGLT-2i) on liver and non-liver outcomes among patients with diabetic MASLD.

DESIGN

This population-based cohort study retrieved patients with diabetic MASLD from Merative Marketscan Research Databases (April 2013 and December 2021). The active comparator was other glucose-lowering drugs (oGLDs). Primary outcomes were liver complications including hepatocellular carcinoma (HCC) and liver cirrhosis, as well as non-liver complications including cardiovascular disease (CVD), chronic kidney disease (CKD) and non-liver cancer. Propensity score matching was applied and Cox regression models were conducted.

RESULTS

Compared with oGLD, SGLT-2i users had significantly lower risk of HCC (HR 0.76, 95% CI 0.62 to 0.93), liver cirrhosis (HR 0.80, 95% CI 0.76 to 0.84), CVD (HR 0.82, 95% CI 0.79 to 0.85) and CKD (HR 0.66, 95% CI 0.62 to 0.70), non-liver cancer (HR 0.81, 95% CI 0.76 to 0.86). Compared with patients without metformin and SGLT-2i, a stepwise decreasing risk was observed in users of either metformin or SGLT-2i (HRs 0.76-0.97) and in users of both medications (HRs 0.58-0.79). The lower risk also was shown in liver decompensation, compensated cirrhosis, major CVD, end-stage renal disease and specific common cancers (HRs 0.61-0.84).

CONCLUSION

In a nationwide cohort, SGLT-2i users were associated with a substantially lower risk of liver and non-liver complications than oGLD users among patients with diabetic MASLD. The risk was further reduced with concomitant metformin use.

Diabetes as a risk factor for MASH progression

Non-alcoholic (now: metabolic) steatohepatitis (MASH) is the progressive inflammatory form of metabolic dysfunction-associated steatotic liver disease (MASLD), which often coexists and mutually interacts with type 2 diabetes (T2D), resulting in worse hepatic and cardiovascular outcomes. Understanding the intricate mechanisms of diabetes-related MASH progression is crucial for effective therapeutic strategies. This review delineates the multifaceted pathways involved in this interplay and explores potential therapeutic implications. The synergy between adipose tissue, gut microbiota, and hepatic alterations plays a pivotal role in disease progression. Adipose tissue dysfunction, particularly in the visceral depot, coupled with dysbiosis in the gut microbiota, exacerbates hepatic injury and insulin resistance. Hepatic lipid accumulation, oxidative stress, and endoplasmic reticulum stress further potentiate inflammation and fibrosis, contributing to disease severity. Dietary modification with weight reduction and exercise prove crucial in managing T2D-related MASH. Additionally, various well-known but also novel anti-hyperglycemic medications exhibit potential in reducing liver lipid content and, in some cases, improving MASH histology. Therapies targeting incretin receptors show promise in managing T2D-related MASH, while thyroid hormone receptor-β agonism has proven effective as a treatment of MASH and fibrosis.

Diabetes distress profiles and health outcomes of individuals with type 2 diabetes and overweight/obesity: A cluster analysis

AIMS

To determine the prevalence and patterns of diabetes distress, and evaluate the differences in health outcomes between profiles.

METHODS

This cross-sectional study included 330 adults with T2DM and overweight/obesity. The participants completed questionnaires on diabetes distress, sleep quality, self-efficacy, depression, anxiety and positive and negative affect. A cluster analysis was performed to identify different patterns of diabetes distress and one-way ANOVA was used to investigate the differences in physical and psychological outcomes between profiles.

RESULTS

30.6% of patients were identified as moderately to highly distressed, with the regimen-related distress found to be the most prominent. The Cluster analysis revealed four distinct clusters: (1) "comprehensively exhausted profile"; (2) "strained profile"; (3) "high internal anguish profile"; (4) "unperturbed profile". The measures of fasting blood glucose (FBG), glycated hemoglobin (HbA1c), low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, sleep quality, depression, anxiety, positive and negative affect and self-efficacy differ between clusters.

CONCLUSIONS

This study identified important differences that existed in patterns of diabetes distress among people with T2DM and overweight/obesity, and this variation can be utilized to tailor intervention strategies to the particular needs of different subgroups within individuals with T2DM.

Bone properties in persons with type 1 diabetes and healthy controls - A cross-sectional study

BACKGROUND

The risk of fractures is increased in persons with type 1 diabetes (T1D) and assessment of bone health has been included in the 2024 updated Standards of Care by The American Diabetes Association (ADA). Previous studies have found that in T1D bone metabolism, mineral content, microstructure, and strength diverge from that of persons without diabetes. However, a clear description of a T1D bone phenotype has not yet been established. We investigated bone mechanical properties and microstructure in T1D compared with healthy controls. For the potential future introduction of additional bone measures in the clinical fracture risk assessment, we aimed to assess any potential associations between various measures related to bone indices in subjects with T1D.

METHODS

We studied human bone indices in a clinical cross-sectional setup including 111 persons with early-onset T1D and 37 sex- and age-matched control persons. Participants underwent hip and spine DXA scans for bone mineral density (BMD) of the femoral neck (FN), total hip (TH), and lumbar spine (LS), and TBS evaluation, microindentation of the tibial shaft for Bone Material Strength index (BMSi), and high-resolution periphery quantitative computed tomography (HRpQCT) of the distal radius and tibia for volumetric BMD (vBMD) and structural measures of trabecular and cortical bone. Results are reported as means with (standard deviation) or (95 % confidence intervals (CI)), medians with [interquartile range], and differences are reported with (95 % CI).

RESULTS

The study included 148 persons aged 20 to 75 years with a median age of 43.2 years. The T1D group who had all been diagnosed with T1D before the age of 18 years demonstrated values of HbA1c ranging from 39 to 107 mmol/mol and a median HbA1c of 57 mmol/mol. The BMD did not differ between groups (the mean difference in FN-BMD was 0.026 g/cm2 (-0.026; 0.079), p = 0.319) and the median BMSi was comparable in the two groups (79.2 [73.6; 83.8] in the T1D group compared with 77.9 [70.5, 86.1] in the control group). Total and trabecular vBMD (Tb.vBMD), cortical thickness (Ct.Th), and trabecular thickness (Tb.Th) of both radius and tibia were lower in participants with T1D. The mean Tb.vBMD at the radius was 143.6 (38.5) mg/cm3 in the T1D group and 171.5 (37.7) mg/cm3 in the control group, p < 0.001. The mean Ct. Thd of the radius was 0.739 mm (0.172) in the T1D group and 0.813 (0.188) in the control group, p = 0.044. Crude linear regressions revealed limited agreement between BMSi and Tb.vBMD (p = 0.010, r2 = 0.040 at the radius and p = 0.008, r2 = 0.040 at the tibia and between BMSi and the estimated failure load (FL) at the tibia (p < 0.001, r2 = 0.090). There were no significant correlations between BMSi and Ct.Th. TBS correlated with Tb.vBMD at the radius (p = 0.008, r2 = 0.044) and the tibia (p = 0.001, r2 = 0.069), and with the estimated FL at the distal tibia (p = 0.038, r2 = 0.026).

CONCLUSION

In this study, we examined the bones of persons with well-controlled, early-onset T1D. Compared with sex- and age-matched healthy control persons, we found reduced total and trabecular vBMD, as well as decreased trabecular and cortical thickness. These results suggest that a debut of T1D before reaching peak bone mass negatively impacts bone microarchitecture. No differences in areal BMD or BMSi were observed. Although the variations in total hip BMD reflect some variation in the vBMD, the reduction in trabecular bone mineral density was not captured by the DXA scan. Consequently, fracture risk may be underestimated when relying on DXA, and further research into fracture risk assessment in T1D is warranted.

Depression symptoms, wellbeing, health-related quality of life, and diabetes-related distress in novel subtypes of recent-onset diabetes in Germany: a 5-year observational follow-up study

BACKGROUND

The subjective experiences of individuals living with diabetes is commonly assessed with patient-reported outcomes (PROs; eg, depression symptoms, wellbeing, health-related quality of life [HRQOL], and diabetes-related distress). Cluster analyses have identified novel diabetes subtypes differing in phenotypic and metabolic characteristics. We aimed to investigate associations between these subtypes and PROs and whether subtype predicted PROs 5 years later.

METHODS

Baseline (<12 months after a diabetes diagnosis) and 5-year follow-up data were collected from German Diabetes Study (GDS) participants. Multiple regressions were applied to analyse associations between diabetes subtypes and depression symptoms (Center for Epidemiologic Studies Depression Scale), wellbeing (WHO-5), HRQOL (SF-36), and diabetes-related distress (Problem Areas in Diabetes Scale).

FINDINGS

Cluster analyses at baseline (n=1391) identified participants with severe autoimmune diabetes (SAID, 417 [30%]), severe insulin-deficient diabetes (SIDD, 33 [2%]), severe insulin-resistant diabetes (SIRD, 150 [11%]), mild obesity-related diabetes (MOD, 354 [25%]), and mild age-related diabetes (MARD, 437 [31%]). At baseline, multiple regression analyses showed that participants with SIRD had higher depression symptoms than participants with MARD and lower physical HRQOL than all other subtypes. Participants with SAID reported higher depression symptoms and lower mental HRQOL than participants with MARD, higher physical HRQOL than participants with MARD and MOD, and higher diabetes-related distress than most other subtypes. At the 5-year follow-up, clustering predicted no statistically significant changes in PROs after adjustment for multiple testing, whereas descriptive analyses demonstrated that individuals with SIRD were more likely to experience clinically relevant depression symptoms (16% vs 6%) and low wellbeing (31% vs 14%), respectively, than individuals with MARD.

INTERPRETATION

Diabetes subtypes already differ in PROs at diabetes diagnosis. Our analyses had limited predictive power during follow-up. However, our findings suggest that clustering could predict future changes in depression symptoms.

FUNDING

The GDS was initiated and financed by the German Diabetes Center, which is funded by the German Federal Ministry of Health, the Ministry of Culture and Science of the state of North Rhine-Westphalia, and by the German Federal Ministry of Education and Research to the German Center for Diabetes Research.

UCF101 Rescues against Diabetes-Evoked Cardiac Remodeling and Contractile Anomalies through AMP-Activated Protein Kinase-Mediated Induction of Mitophagy

INTRODUCTION

Diabetes mellitus is known to provoke devastating anomalies in myocardial structure and function, while effective therapeutic regimen is still lacking. The selective protease inhibitor UCF101 (5-[5-(2-nitrophenyl) furfuryl iodine]-1,3-diphenyl-2-thiobarbituric acid) has been shown to fend off ischemic heart injury, although its impact on diabetic cardiomyopathy remains elusive.

METHODS

Our present work was conducted to examine the effect of UCF101 on experimental diabetes-evoked cardiac geometric and functional abnormalities as well as mechanisms involved. Adult mice were made diabetic using streptozotocin (STZ, 50 mg/kg, i.p., for 5 days) while receiving UCF101 (7.15 mg/kg, i.p.).

RESULTS

STZ evoked cardiac hypertrophy, interstitial fibrosis, mitochondrial ultrastructural damage, oxidative stress, dampened autophagy (LC3B, Beclin 1, elevated p62), mitophagy (FUNDC1 and Parkin with upregulated TOM20), increased left ventricular end systolic diameter, reduced fractional shortening, ejection fraction, cardiomyocyte shortening capacity, velocities of shortening/re-lengthening, and rise in intracellular Ca2+ in conjunction with elongated diastole and intracellular Ca2+ removal, the responses were overtly reconciled by UCF101 with little effects from UCF101 itself. Levels of cell injury markers Omi/HtrA2, TNFα, and stress signaling (JNK, ERK, p38) were overtly enhanced along with compromised phosphorylation of cellular fuel AMP-activated protein kinase (AMPK) (Thr172) and cell survival molecule GSK3β, as well as downregulated SERCA2a and elevated phospholamban, the effect was reversed by UCF101 (except for SERCA2a). AMPK knockout, pharmacological inhibition, the mitophagy inhibitor liensinine, and parkin knockout nullified UCF101-offered cardioprotection in diabetes. UCF101 reversed STZ-induced upregulation in the AMPK degrading enzymes PP2A and PP2C.

CONCLUSION

These findings suggest that UCF101 rescues diabetes-mediated alterations in cardiac structure and function, likely through AMPK-mediated regulation of mitophagy.

GDF-15 improves the predictive capacity of Steatotic liver disease non-invasive tests for incident morbidity and mortality risk for cardio-renal-metabolic diseases and malignancies

BACKGROUND & AIMS

Noninvasive tools (NITs) are currently used to stratify the risk of having or developing hepatic steatosis or fibrosis. Their performance and a proteomic-enabled improvement in forecasting long-term cardio-renal-metabolic morbidity, malignancies, as well as cause-specific and all-cause mortality, are lacking. Therefore, the performance of established NITs needs to be investigated in identifying cardio-renal-metabolic morbidity, malignancies, cause-specific and overall mortality and improve their performance with novel, proteomic-enabled NITs, including growth differentiation factor 15 (GDF-15), allowing multipurpose utilization.

METHODS

502,359 UK Biobank participants free of the study outcomes at baseline with a 14-year median follow-up were grouped into three categories: a) general population, b) potentially metabolic dysfunction-associated steatotic liver disease (MASLD) population, c) individuals with type 2 diabetes mellitus. The investigated NITs include Aspartate aminotransferase to Platelet Ratio Index (APRI), Fibrosis 4 Index (FIB-4), Fatty Liver Index (FLI), Hepatic Steatosis Index (HSI), Lipid Accumulation Product (LAP), and metabolic dysfunction-associated fibrosis (MAF-5) score.

RESULTS

Adding GDF-15 to the existing NITs led to significantly increased prognostic performance compared to the traditional NITs in almost all instances, reaching substantially high C-indices, ranging between 0.601 and 0.808, with an overall >0.2 improvement in C-index. Overall, with the GDF-15 enhanced NITs, up to more than seven times fewer individuals need to be screened to identify more incident cases of adverse outcomes compared to the traditional NITs. The cumulative incidence of all outcomes, based on the continuous value percentiles of NITs, is increasing exponentially in the upper quintile of the GDF-15 enhanced NITs.

CONCLUSIONS

The herein-developed GDF-15 enhanced indices demonstrate higher screening effectiveness and significantly improved prognostic abilities, which are reduced to practice through an easy-to-use web-based calculator tool (https://clinicalpredictor.shinyapps.io/multimorbidity-mortality-risk/).

The effect of nutritional education on blood glycemic, lipidemic, and body mass index control among sample of type 2 diabetes

BACKGROUND

Type 2 diabetes mellitus is a chronic metabolic disorder, characterized by poor glycemic control nutritional education enhances people's knowledge on healthy food choices that improve blood glycemic and lipidemic control leading to better overall health.

OBJECTIVES

This study is to examine the effect of nutritional education on the glycemic/lipidemic control and the body mass index in patient with type 2 diabetes mellitus.

METHODS

A quasi-experimental study was conducted on 40 patients with type 2 diabetes mellitus and recruited by non-probability convenience sampling method over 3 months duration. BMI, HbA1c, total cholesterol, low density lipoprotein-C, high density lipoprotein-C, and triglyceride were measured at baseline and after 3 months during which during which five nutritional educational lectures were done.

RESULTS

After 3 months of nutritional education, there were a significant reduction in HbA1c % from 9.53 to 8.09 (P < 0.001) and body mass index from 32.19 to 31.58 (P = 0.001) and also slight but non-significant changes in cholesterol, LDL, triglyceride, and HDL (7.05 ± 38.428, 5.00 ± 29.858, 9.10 ± 85.386, 0.24 ± 3.612 respectively) (P = 0.253, 0.296, 0.668, and 0.504 respectively).

CONCLUSIONS

Nutritional education program is effective to decrease HbA1c % and body mass index.

Burden of Herpes Zoster in Individuals With Chronic Conditions in the Republic of Korea: A Nationwide Population-Based Database Study

Background

Chronic conditions (CCs) may increase the risk of herpes zoster (HZ) infection, leading to a greater healthcare burden in these individuals compared to those without CCs. It is therefore clinically important to quantify HZ disease burden in individuals with and without CCs, given the rapidly aging population in the Republic of Korea (ROK).

Methods

This retrospective cohort study examines the trends in incidence rates (IRs) and incidence rate ratios (IRRs) in individuals aged ≥18 years with CCs, using the National Health Insurance Service National Sample Cohort (NHIS-NSC) database from 2010 to 2019. These patients were stratified by age group, sex, HZ complications, and CCs. The annual average number of HZ patients, IRs, and IRRs were calculated for individuals with and without CCs.

Results

In total, 729 347 patients with HZ were eligible for the study. HZ IRs were highest in patients with diabetes, followed by chronic obstructive pulmonary disease, chronic kidney disease, asthma, and chronic liver disease, with HZ IRRs following a similar trend. Overall, HZ IRs generally increased with age, typically peaking at 60-64 or 65-69 years, and were similar for females and males. HZ IRs were highest among patients without complications, followed by HZ with other, cutaneous, ocular, and neurologic complications across all CCs. For each of the CCs, HZ IRs were consistently higher than those of the non-CC population regardless of sex.

Conclusions

The findings of this study reiterate the importance of HZ prevention for healthy aging, especially for CC populations at increased risk of HZ in the ROK.

The Global Epidemiology of Nonalcoholic Fatty Liver Disease and Nonalcoholic Steatohepatitis Among Patients With Type 2 Diabetes

BACKGROUND & AIMS

Nonalcoholic fatty liver disease (NAFLD), now known as metabolic dysfunction associated steatotic liver disease (MASLD), is closely associated with type 2 diabetes (T2D). Our aim was to estimate the most recent global prevalence of NAFLD/MASLD, nonalcoholic steatohepatitis (NASH), now known as metabolic dysfunction associated steatohepatitis (MASH), advanced fibrosis, and mortality among patients with T2D.

METHODS

We systematically searched PubMed and Ovid MEDLINE for terms including NAFLD, NASH, and T2D published in 1990-2023 according to PRISMA. The meta-analysis was conducted using a random-effects model. Assessment of bias risk used the Joanna Briggs Institute appraisal tool.

RESULTS

From 3134 studies included in the initial search, 123 studies (N = 2,224,144 patients with T2D) were eligible. Another 12 studies (N = 2733 T2D patients with liver biopsy) were eligible for histologic assessments. The global pooled prevalence of NAFLD/MASLD among patients with T2D was 65.33% (95% confidence interval, 62.35%-68.18%). This prevalence increased from 55.86% (42.38%-68.53%) in 1990-2004 to 68.81% (63.41%-73.74%) in 2016-2021 (P = .073). The highest NAFLD/MASLD prevalence among T2D patients was observed in Eastern Europe (80.62%, 75.72%-84.73%), followed by the Middle East (71.24%, 62.22%-78.84%), and was lowest in Africa (53.10%, 26.05%-78.44%). Among patients with liver biopsy data, the global pooled prevalence of NASH/MASH, significant fibrosis, and advanced fibrosis was 66.44% (56.61%-75.02%), 40.78% (24.24%-59.70%), and 15.49% (6.99%-30.99%), respectively. The pooled all-cause mortality was 16.79 per 1000 person-years (PY) (10.64-26.40), 4.19 per 1000 PY (1.34-7.05) for cardiac-specific mortality; 6.10 per 1000 PY (0.78-4.88) for extrahepatic cancer-specific mortality; and 2.15 per 1000 PY (0.00-2.21) for liver-specific mortality.

CONCLUSIONS

The prevalence of NAFLD/MASLD among T2D is high and growing. The majority of NAFLD/MASLD patients with T2D have NASH/MASH, and a significant proportion have advanced fibrosis.

Impact of baseline FIB-4 score on efpeglenatide benefits on cardiovascular outcomes in people with type 2 diabetes: a participant-level exploratory analysis of the AMPLITUDE-O trial

AIMS

To estimate the incidence of major adverse cardiovascular events (MACE), expanded MACE, and MACE or Death across Fibrosis- 4 score (FIB-4) categories in people with type 2 diabetes and to determine whether efpeglenatide's effect varies with increasing FIB-4 severity.

MATERIALS AND METHODS

AMPLITUDE-O trial data were used to estimate the relationship of FIB-4 score categories to the hazard of MACE, expanded MACE, and MACE or death. Interactions on these outcomes between baseline FIB-4 score, and between FIB-4 score and efpeglenatide were also assessed.

RESULTS

Baseline FIB-4 score was available for 4059 participants (99.6%) allowing subdivision of the population in tertiles. During a median follow-up of 1.8 years, numerical increases in the incidence of all 3 outcomes did not change significantly across tertiles of FIB-4 score (P for trend ≥ 0.25) with negligible relationship of the score to incident outcomes (MACE HR, per 1 SD higher score, 95% CI: 1.00, 0.89-1.13). Efpeglenatide's effect on all MACE outcomes did not vary across FIB-4 tertiles (all interaction p values ≥ 0.64).

CONCLUSIONS

In high-risk people with type 2 diabetes, the degree of liver fibrosis, as estimated by FIB-4 score, was not related to incident cardiovascular outcomes. The beneficial effect of efpeglenatide on these outcomes is independent of FIB-4 category.

Knowledge, attitudes, and practices among patients with diabetes mellitus and hyperuricemia toward disease self-management

Background

This study aimed to assess the knowledge, attitudes and practices (KAP) among patients with diabetes mellitus and hyperuricemia toward disease self-management.

Methods

This web-based cross-sectional study was conducted between June 2023 and January 2024 at Heilongjiang Provincial Hospital. A self-designed questionnaire was developed to collect demographic information of patients with diabetes mellitus and hyperuricemia, and assess their knowledge, attitudes and practices toward disease self-management.

Results

A total of 482 participants were enrolled in this study, among them, 364 (75.52%) were male, 235 (48.76%) were aged between 40 and 59 years, 226 (46.89%) had a body mass index (BMI) ranging from 24 to 28 kg/m2, 337 (69.92%) had received a diagnosis of diabetes for a duration of 2 years or more, while 245 (50.83%) had been diagnosed with hyperuricemia for a similar duration. Their median (range) knowledge, attitude and practice scores were 10.00 (9.00, 11.00) (possible range: 0-12), 38.00 (36.00, 40.00) (possible range: 9-45), and 30.00 (26.00, 34.75) (possible range: 10-50), respectively. The path analysis demonstrated that knowledge had direct effects on attitude (β = 0.508, p < 0.001), and attitude had direct effects on practice (β = 0.448, p < 0.001). Additionally, there was an indirect effect of knowledge on practice mediated through attitude, with a path coefficient of 0.228 (p < 0.001).

Conclusion

This study demonstrates that patients with diabetes mellitus and hyperuricemia exhibit relatively proficient responses to certain items within the KAP dimensions. However, it also exposes a certain degree of inadequacy in the KAP level toward disease management. Interventions should focus on improving patients' understanding of their conditions while fostering positive attitudes, ultimately translating into better self-management practices.

Body composition in a pediatric population with type-1 diabetes - The importance of planned physical exercise

OBJECTIVE AND METHODS

This study aimed to assess the body composition of pediatric patients with type-1 diabetes (T1D) in a Portuguese pediatric endocrinology/diabetic clinic, using the InBody 570 bioimpedance system. Preschool children (<6 years) and those recently diagnosed (<6 months) were excluded.

RESULTS

The study included 78 patients (53% female). Median age at assessment was 14 years, with 81% pubertal children. Eighty-seven percent were using continuous subcutaneous insulin infusion (CSII), 25% with an automated closed-loop model. Median HbA1c was 7.3%. Most had an adequate body mass index (BMI) standard deviation score (62%) and 48% engaged in regular physical exercise (PE) outside of school. Median percentage body fat (PBF) was 21.5% and was abnormal in 48%, with median visceral adiposity of 4. Despite adequate BMI, 11% had excessive PBF. PBF was significantly associated with visceral fat (r=0.79; P<0.001), female gender (P<0.001) and PE performed out of school (P=0.005). PE was associated with lower PBF (P=0.005), lower visceral fat (P=0.002), and higher muscle-to-fat ratio (P=0.006).

CONCLUSION

Engaging in physical exercise out of school correlated significantly with improved body composition, characterized by reduced PBF and diminished visceral adiposity. Considering the known benefits of physical exercise for metabolic and glycemic control, this study highlights the importance of promoting regular physical exercise in T1D patients.

Optimizing the lifestyle of patients with type 2 diabetes mellitus - Systematic review on the effects of combined diet-and-exercise interventions

AIM

To investigate the effects of combined diet-and-exercise interventions in patients with type 2 diabetes mellitus (T2DM).

DATA SYNTHESIS

A systematic literature search was conducted on PubMed, Web of Science, SPORTDiscus and BISp Surf databases (latest update in June 2024). A total of 14706 records was identified. After screening procedures, 11 randomized controlled trials (n = 24 reports) were included. The included studies compared either the effects of a) a combined intervention versus a diet-only intervention or b) different combinations of diet and exercise. The overall quality of the included study reports was moderate (evaluated with the Risk of Bias 2 (RoB2) tool). Effects of adding exercise to a (calorie-restricted) diet were primarily reflected in increased physical fitness/performance. In far fewer cases, additional beneficial effects on glycemic control, number of subjects taking medication, body weight, body composition, or lipid profile were reported. Combined with regular exercise, an energy-restricted low-carbohydrate (LC) diet with either high-fat (HF) or high-protein (HP) contents showed superior effects compared with an energy-matched conventional (CONV) diet in terms of improvements in medication use (HF-LC versus CONV diet), lipids (HF-LC or HP-LC versus CONV diet) or wellbeing (HP-LC versus CONV diet) in some studies.

CONCLUSIONS

Complementing a dietary intervention with regular exercise can have additional health benefits in T2DM, specifically improved physical fitness/performance. LC diets might be superior to other diets when combined with regular exercise. Other diet-and-exercise combinations than those analyzed in this review need to be investigated.

Knowledge about metabolic dysfunction-associated steatotic liver disease among the medical professionals from countries in the MENA region

INTRODUCTION AND OBJECTIVES

Given the substantial burden of metabolic dysfunction-associated steatotic liver disease (MASLD), there is an urgent need to assess knowledge and awareness levels among physicians. We assessed MASLD knowledge among healthcare providers from Saudi Arabia, Egypt, and Türkiye.

MATERIALS AND METHODS

Two global surveys containing 54-59 items assessed awareness and knowledge of MASLD/NAFLD- one was for hepatologists and gastroenterologists, and the second was for non-specialists (e.g. endocrinologists, primary care providers [PCPs], and other healthcare professionals). Data were collected using an electronic data collection form. Knowledge scores and variables associated with higher knowledge scores were compared across all specialties.

RESULTS

A total of 584 physicians completed the survey (126 hepatologists, 178 gastroenterologists (GEs), 38 endocrinologists, 242 PCPs/others). Practice guidelines were the primary source for knowledge across all specialties (43-51%), then conferences (24-31%) except PCPs/others who selected the internet as the second common source (25%). Adherence to societal guidelines varied by specialty (81-84% of specialists vs 38-51% of non-specialists). Hepatologists and GEs showed similar mean knowledge scores (51-72% correct answers across three knowledge domains, p > 0.05); endocrinologists outperformed PCPs/others in knowledge scores in all knowledge domains, including Epidemiology/Pathogenesis (72% vs. 60%), Diagnostics (73% vs. 67%), and Treatment (78% vs. 67%) (all p < 0.01). Hospital-based practice and seeing a greater number of patients with MASLD/NAFLD were identified as independent predictors of higher knowledge scores among specialists (both p < 0.05).

CONCLUSIONS

A knowledge gap in the identification, diagnosis, and management of MASLD/NAFLD was found despite the growing burden of MASLD/NAFLD in Saudi Arabia, Egypt, and Türkiye. Education to increase awareness is needed.

Advances and counterpoints in type 2 diabetes. What is ready for translation into real-world practice, ahead of the guidelines

This review seeks to address major gaps and delays between our rapidly evolving body of knowledge on type 2 diabetes and its translation into real-world practice. Through updated and improved best practices informed by recent evidence and described herein, we stand to better attain A1c targets, help preserve beta cell integrity and moderate glycemic variability, minimize treatment-emergent hypoglycemia, circumvent prescribing to "treatment failure," and prevent long-term complications. The first topic addressed in this review concerns updates in the 2023 and 2024 diabetes treatment guidelines for which further elaboration can help facilitate integration into routine care. The second concerns advances in diabetes research that have not yet found their way into guidelines, though they are endorsed by strong evidence and are ready for real-world use in appropriate patients. The final theme addresses lingering misconceptions about the underpinnings of type 2 diabetes-fundamental fallacies that continue to be asserted in the textbooks and continuing medical education upon which physicians build their approaches. A corrected and up-to-date understanding of the disease state is essential for practitioners to both conceptually and translationally manage initial onset through late-stage type 2 diabetes.

Effects of luseogliflozin on suspected MASLD in patients with diabetes: a pooled meta-analysis of phase III clinical trials

BACKGROUND

Luseogliflozin, a sodium-glucose cotransporter 2 inhibitor, potentially exerts pleiotropic effects on the liver. However, the sufficient evidence is still lacking. We aimed to investigate the effects of luseogliflozin on hepatic steatosis, fibrosis, and cardiometabolic risk factors in diabetic patients by a pooled meta-analysis.

METHODS

In this pooled meta-analysis, we enrolled diabetic patients who participated in phase III clinical trials of luseogliflozin (luseogliflozin group n = 302, placebo group n = 191). The primary outcomes were changes in fatty liver index (FLI) and Hepamet fibrosis score (HFS) after 24 weeks. The secondary outcomes were changes in cardiometabolic risk factors after 24 weeks. Statistical analysis was performed using propensity scoring analysis by the inverse probability of treatment weighting method.

RESULTS

Primary outcomes: Luseogliflozin significantly decreased FLI compared to placebo after 24 weeks (adjusted coefficient - 5.423, 95%CI - 8.760 to - 2.086, P = 0.0016). There was no significant difference in changes in HFS between the two groups. However, luseogliflozin significantly decreased HFS compared to placebo in diabetic patients with ALT > 30 U/L (adjusted coefficient - 0.039, 95%CI - 0.077 to - 0.001, P = 0.0438) and with FIB-4 index > 1.3 (adjusted coefficient - 0.0453, 95%CI - 0.075 to - 0.016, P = 0.0026). Secondary outcom8es: Luseogliflozin significantly decreased HbA1c level, HOMA-IR value, BMI, and uric acids level, and increased HDL cholesterol level compared to placebo.

CONCLUSIONS

This pooled meta-analysis demonstrated that 24-week treatment with luseogliflozin improved hepatic steatosis and fibrosis indexes in diabetic patients, especially those with liver injury. Furthermore, luseogliflozin improved various cardiometabolic risk factors. Thus, luseogliflozin may be useful for improving MASLD in diabetic patients.

Therapeutic Effects of Semaglutide on Nonalcoholic Fatty Liver Disease with Type 2 Diabetes Mellitus and Obesity: An Open-Label Controlled Trial

BACKGROUND

GLP-1 receptor agonists (GLP-1 RAs) have been shown to improve glycemic control and insulin sensitivity and reduce body weight in obese patients with type 2 diabetes mellitus (T2D). This trial sought to evaluate the therapeutic effect of oral and subcutaneous semaglutide in NAFLD and its sequelae in obesity and/or T2D.

METHODS

In an open-labelled intervention study, the sample was 180 patients classified into three parallel groups (1:1:1): group I received oral semaglutide, group II patients received injectable semaglutide, and group III received pioglitazone and/or vitamin E. Patients were evaluated at 6 and 12 months.

RESULTS

There was a substantial improvement in lipid profile, liver enzymes, and body mass index, especially in group II. As for HDL, only group II showed a consistent increase at both 6 months (51 ± 4.62 mg/dL) and 12 months (50.08 ± 2.45 mg/dL) compared with baseline (45.6 ± 6.37 mg/dL) (p-value < 0.001). Despite the non-significant difference in NAFLD fibrosis score (NFS) (p-value = 0.45 and 0.63), group II had significantly lower scores of the fibrosis-4 score (FIB-4), liver stiffness measurement (LSM), and controlled attenuation parameter (CAP) at 6 and 12 months (p-value < 0.001). Conclusions: Semaglutide improves lipid profile, liver steatosis, and fibrosis parameters and reduces the BMI in T2D and obese patients with NAFLD.

Efficiency of periodontal treatment to improve type 2 diabetes mellitus outcomes: A systematic review and meta-analysis of economic evaluations

BACKGROUND

To assess the efficiency of periodontal treatment (PT) in improving diabetes-related outcomes in adults with type 2 diabetes mellitus (T2DM) and periodontitis, providing an updated and comprehensive synthesis from economic evaluations (EE).

METHODS

Seven databases and one register were independently searched by two reviewers for articles published up to 8 May 2024. Studies that assessed the efficiency of PT versus no treatment or other dental treatments were included. Risk of bias was assessed using the Cochrane RoB 2, ROBINS-I and ECOBIAS tools for the first stage of EE and the CHEERS checklist and NICE quality appraisal tool for overall EE. Qualitative and quantitative syntheses of the articles were conducted and assessed using the GRADE approach.

RESULTS

Eleven studies were included. PT reduces total healthcare costs, including inpatient and outpatient, diabetes-related costs and other drug costs (low to moderate certainty). A total incremental net benefit of USD 12 348 (2022 currency, 95% CI 12 195-12 500) was estimated from three high-quality model-based cost-utility analyses (high certainty).

DISCUSSION

The inclusion of PT in the comprehensive treatment of patients with T2DM and periodontitis is cost-effective. Future research is required to ensure the transferability of these findings and inform decision makers from different countries.

Polyunsaturated fatty acids and diabetic microvascular complications: a Mendelian randomization study

Background

Observational studies and clinical trials have implicated polyunsaturated fatty acids (PUFAs) in potentially safeguarding against diabetic microvascular complication. Nonetheless, the causal nature of these relationships remains ambiguous due to conflicting findings across studies. This research employs Mendelian randomization (MR) to assess the causal impact of PUFAs on diabetic microvascular complications.

Methods

We identified instrumental variables for PUFAs, specifically omega-3 and omega-6 fatty acids, using the UK Biobank data. Outcome data regarding diabetic microvascular complications were sourced from the FinnGen Study. Our analysis covered microvascular outcomes in both type 1 and type 2 diabetes, namely diabetic neuropathy (DN), diabetic retinopathy (DR), and diabetic kidney disease (DKD). An inverse MR analysis was conducted to examine the effect of diabetic microvascular complications on PUFAs. Sensitivity analyses were performed to validate the robustness of the results. Finally, a multivariable MR (MVMR) analysis was conducted to determine whether PUFAs have a direct influence on diabetic microvascular complications.

Results

The study indicates that elevated levels of genetically predicted omega-6 fatty acids substantially reduce the risk of DN in type 2 diabetes (odds ratio (OR): 0.62, 95% confidence interval (CI): 0.47-0.82, p = 0.001). A protective effect against DR in type 2 diabetes is also suggested (OR: 0.75, 95% CI: 0.62-0.92, p = 0.005). MVMR analysis confirmed the stability of these results after adjusting for potential confounding factors. No significant effects of omega-6 fatty acids were observed on DKD in type 2 diabetes or on any complications in type 1 diabetes. By contrast, omega-3 fatty acids showed no significant causal links with any of the diabetic microvascular complications assessed.

Conclusions

Our MR analysis reveals a causal link between omega-6 fatty acids and certain diabetic microvascular complications in type 2 diabetes, potentially providing novel insights for further mechanistic and clinical investigations into diabetic microvascular complications.

Impact of School Nurse on Managing Pediatric Type 1 Diabetes with Technological Devices Support: A Systematic Review

INTRODUCTION

Type 1 diabetes (T1D) is a disease that primarily occurs in pediatric populations. A school nurse (SN) can provide valuable support in the school setting for minors affected by this condition.

METHODS

The main objective of this study was to evaluate the impact of nursing care provided to adolescents and children with T1D using technological devices in school. Qualitative and quantitative outcomes considered in the included studies were collected and discussed. A systematic review was conducted in the PubMed, CINAHL, and Scopus databases and reported thought the PRISMA guidelines.

RESULTS

Eleven studies were included. The results showed that SNs need to enhance both their skills and organization to effectively manage young patients with T1D using technology. The response of both the pediatric population and their caregivers to the disease management by a SN has been positive.

CONCLUSIONS

The management of chronic diseases is one of the most urgent public health issues, especially for Western healthcare systems. Proper management of patients with T1D at the school level is definitely an aspect that policymakers and healthcare managers should consider to improve the quality of life of this extremely vulnerable population, particularly those using technological management T1D.

Preventing diabetes complications

The key aim of diabetes management is to prevent complications, which are a major cause of morbidity and mortality. At an individual level, people with diabetes are less likely than they were several decades ago to experience classical macrovascular and microvascular complications as a result of improvements in modifiable cardiovascular risk factors and preventive healthcare. However, a significant burden of diabetes complications persists at a population level because of the increasing incidence of diabetes, as well as longer lifetime exposure to diabetes because of younger diagnosis and increased life expectancy. Trials have shown that the most effective strategy for preventing complications of diabetes is a multifactorial approach focussing simultaneously on the management of diet, exercise, glucose levels, blood pressure and lipids. In addition to the cornerstone strategies of addressing diet, exercise and lifestyle measures, the introduction of newer glucose-lowering agents, including sodium-glucose transport protein 2 inhibitors and glucagon-like peptide-1 agonists, have brought about a paradigm shift in preventing the onset and progression of complications of type 2 diabetes, particularly cardiovascular and renal disease. The improvement in rates of classical complications of diabetes over time has been accompanied by a growing awareness of non-traditional complications, including non-alcoholic fatty liver disease. These emerging complications may not respond to a glycaemic-centred approach alone and highlight the importance of foundational strategies centred on lifestyle measures and supported by pharmaceutical therapy to achieve weight loss and reduce metabolic risk in patients living with diabetes.

Automated Comprehensive CT Assessment of the Risk of Diabetes and Associated Cardiometabolic Conditions

Background CT performed for various clinical indications has the potential to predict cardiometabolic diseases. However, the predictive ability of individual CT parameters remains underexplored. Purpose To evaluate the ability of automated CT-derived markers to predict diabetes and associated cardiometabolic comorbidities. Materials and Methods This retrospective study included Korean adults (age ≥ 25 years) who underwent health screening with fluorine 18 fluorodeoxyglucose PET/CT between January 2012 and December 2015. Fully automated CT markers included visceral and subcutaneous fat, muscle, bone density, liver fat, all normalized to height (in meters squared), and aortic calcification. Predictive performance was assessed with area under the receiver operating characteristic curve (AUC) and Harrell C-index in the cross-sectional and survival analyses, respectively. Results The cross-sectional and cohort analyses included 32166 (mean age, 45 years ± 6 [SD], 28833 men) and 27 298 adults (mean age, 44 years ± 5 [SD], 24 820 men), respectively. Diabetes prevalence and incidence was 6% at baseline and 9% during the 7.3-year median follow-up, respectively. Visceral fat index showed the highest predictive performance for prevalent and incident diabetes, yielding AUC of 0.70 (95% CI: 0.68, 0.71) for men and 0.82 (95% CI: 0.78, 0.85) for women and C-index of 0.68 (95% CI: 0.67, 0.69) for men and 0.82 (95% CI: 0.77, 0.86) for women, respectively. Combining visceral fat, muscle area, liver fat fraction, and aortic calcification improved predictive performance, yielding C-indexes of 0.69 (95% CI: 0.68, 0.71) for men and 0.83 (95% CI: 0.78, 0.87) for women. The AUC for visceral fat index in identifying metabolic syndrome was 0.81 (95% CI: 0.80, 0.81) for men and 0.90 (95% CI: 0.88, 0.91) for women. CT-derived markers also identified US-diagnosed fatty liver, coronary artery calcium scores greater than 100, sarcopenia, and osteoporosis, with AUCs ranging from 0.80 to 0.95. Conclusion Automated multiorgan CT analysis identified individuals at high risk of diabetes and other cardiometabolic comorbidities. © RSNA, 2024 Supplemental material is available for this article.

Associations of micronutrients and lipids with prediabetes and glycemic parameters in adolescent girls of the rural DERVAN cohort (DERVAN-9)

Background

We investigated the associations of micronutrients and lipids with prediabetes, glycemic parameters, and glycemic indices among the adolescent girls of the DERVAN (aDolescent and prEconception health peRspectiVe of Adult Non-communicable diseases) cohort study from rural India.

Methods

We recruited 1,520 adolescent girls aged 16-18 years. We measured glycemic parameters (glucose, insulin and HbA1C), lipids (total cholesterol, high-density lipoprotein [HDL], low-density lipoprotein [LDL], and triglycerides), and micronutrients (vitamin B12, folate, and vitamin D). Prediabetes was defined using American Diabetes Association criteria (fasting glucose ≥100 mg/dL or HbA1C ≥5.7%). Glycemic indices (insulin resistance, insulin sensitivity, and β cell function) were calculated using the homeostasis model. Associations of prediabetes, glycemic parameters and glycemic indices with micronutrients and lipids were analyzed by multiple logistic regressions.

Results

The median age and Body Mass Index (BMI) were 16.6 years and 17.6 kg/m2, respectively. Overall, 58% of girls had a low BMI. Median vitamin B12, folate, and vitamin D concentrations were 249.0 pg/mL, 6.1 ng/mL, and 14.2 ng/mL, respectively. The deficiencies observed were 32.1% for vitamin B12, 11.8% for folate, and 33.0% for vitamin D. Median total cholesterol, LDL, HDL, and triglyceride concentrations were 148.0 mg/dL, 81.5 mg/dL, 50.8 mg/dL, and 61.5 mg/dL, respectively. Elevated total cholesterol, LDL, and triglycerides were observed in 4.8, 4.0, and 3.8%, respectively, while low HDL was observed in 12.8%. Prediabetes was observed in 39.7% of the girls. Among lipids, total cholesterol and LDL were higher in girls with prediabetes (p < 0.01 for both). In a multivariate model containing cholesterol and vitamin B12/folate/vitamin D, prediabetes was associated with high cholesterol. Prediabetes was also associated with high LDL, independent of folate and vitamin D. Poor insulin secretion was high in those with low vitamin B12. Elevated insulin resistance was associated with low HDL. The likelihood of high insulin sensitivity was reduced in those with high triglycerides. The likelihood of poor β cell function was high in those with high LDL. Statistical interactions between micronutrients and lipids for prediabetes and glycemic outcomes were not significant.

Conclusion

There was a substantial deficiency of micronutrients and an absence of dyslipidemia. Our results indicate the need for lipid and micronutrient-based interventions in adolescence to improve glycemic outcomes. Maintaining adequate storage of not only micronutrients but also lipids in adolescent girls is likely to reduce diabetes risk in adulthood.

Ultrasonographic Assessment of Tissue Stiffness: Recent Progress in Transient Elastography and Shear Wave Elastography in the Liver and Various Organs

Ultrasonography is a noninvasive and widely accessible modality in clinical practice. Recently, ultrasonography has been used to evaluate tissue stiffness; the two representative techniques are transient elastography (FibroScan®) and shear wave elastography. These modalities are now generally used for the assessment of liver fibrosis, the prediction of hepatocarcinogenesis, and determining prognosis. In addition, shear wave elastography is available, not only for the liver but also for various other organs, including the breast and brain. In the breast and brain, shear wave elastography distinguishes malignant lesions from benign ones. Moreover, shear wave elastography can be useful for differentiating between ischemic and hemorrhagic strokes. This review summarizes the recent progress in transient elastography and shear wave elastography of the liver and introduces the advantages of ultrasonographic assessment of tissue stiffness in various organs, including the breast, brain, kidney, heart, thyroid, pancreas, muscle, and bone.

The Janus of a disease: Diabetes and metabolic dysfunction-associated fatty liver disease

Metabolic Dysfunction-Associated Fatty Liver Disease and Diabetes Mellitus are two prevalent metabolic disorders that often coexist and synergistically contribute to the progression of each other. Several pathophysiological pathways are involved in the association, including insulin resistance, inflammation, and lipotoxicity, providing a foundation for understanding the complex interrelationships between these conditions. The presence of MASLD has a significant impact on diabetes risk and the development of microvascular and macrovascular complications, and diabetes significantly contributes to an increased risk of liver fibrosis progression in MASLD and the development of hepatocellular carcinoma. Moreover, both pathologies have a synergistic effect on cardiovascular events and mortality. Therapeutic interventions targeting MASLD and diabetes are discussed, considering lifestyle modifications, pharmacological agents, and emerging treatment modalities. The review also addresses the challenges in managing these comorbidities, such as the need for personalized approaches and the potential impact on cardiovascular health. The insights gleaned from this analysis can inform clinicians, researchers, and policymakers in developing integrated strategies for preventing, diagnosing, and managing these metabolic disorders.

The resistive and pulsatility indices of the dorsal metatarsal artery for the screening of peripheral lower artery disease in patients with and without diabetes

BACKGROUND

In lower extremity peripheral artery disease (PAD), the ankle-brachial index (ABI) is an easily reproducible diagnostic tool for PAD, but it loses reliability when > 1.4 due to calcification of the vessel wall. Patients with diabetes are at higher risk for wall calcification. In order to overcome the limitation and reliability of ABI, particularly in patients with diabetes, we decided to assess resistive (RI) and pulsatility index (PI) by ultrasound doppler of the dorsal metatarsal artery (DMA).

RESULTS

We therefore analyzed 51 legs (32 patients), evaluating the correlation between PI, RI, and ABI. Patients with diabetes were 21 (65.6 %), accounting for 33 legs (64.7 %). Out of 51 legs assessed, 37 (72.5 %) cases had compressible arteries, whereas in 14 legs (27.5 %) ABI was not calculable due to wall calcification. PAD was significantly associated with lower both RI and PI of the DMA (both p < 0.000). RI, but not PI, showed a significant correlation (r = 0.535) with ABI, when ABI was less than 1.4, but not when ABI > 1.4. When analyzed separately, patients with diabetes showed a similar figure in comparison with those without diabetes (r = 0.600), RI, but not PI, showed a significant correlation with ABI.

CONCLUSION

Dorsal metatarsal artery resistive index (MARI) showed a significant inverse correlation with PAD, similarly to ABI, irrespective of the presence of diabetes. MARI seems to be an effective screening tool for PAD even in patients with wall calcification. Further studies are needed for confirming the results of the present pilot study.

Type 1 diabetes-related distress: Current implications in care

Type 1 diabetes (T1D) is a complex chronic disease associated with major health and economic consequences, also involving important issues in the psychosocial sphere. In this regard, T1D-related distress, defined as the emotional burden of living with T1D, has emerged as a specific entity related to the disease. Diabetes distress (DD) is an overlooked but prevalent condition in people living with T1D, and has significant implications in both glycemic control and mental health in this population. Although overlapping symptoms may be found between DD and mental health disorders, specific approaches should be performed for the diagnosis of this problem. In recent years, different DD-targeted interventions have been postulated, including behavioral and psychosocial strategies. Moreover, new technologies in this field may be helpful to address DD in people living with T1D. In this article, we summarize the current knowledge on T1D-related distress, and we also discuss the current approaches and future perspectives in its management.

Diabetes and infection: review of the epidemiology, mechanisms and principles of treatment

An association between diabetes and infection has been recognised for many years, with infection being an important cause of death and morbidity in people with diabetes. The COVID-19 pandemic has re-kindled an interest in the complex relationship between diabetes and infection. Some infections occur almost exclusively in people with diabetes, often with high mortality rates without early diagnosis and treatment. However, more commonly, diabetes is a complicating factor in many infections. A reciprocal relationship occurs whereby certain infections and their treatments may also increase the risk of diabetes. People with diabetes have a 1.5- to 4-fold increased risk of infection. The risks are the most pronounced for kidney infection, osteomyelitis and foot infection, but are also increased for pneumonia, influenza, tuberculosis, skin infection and general sepsis. Outcomes from infection are worse in people with diabetes, with the most notable example being a twofold higher rate of death from COVID-19. Hyperglycaemia has deleterious effects on the immune response. Vascular insufficiency and neuropathy, together with altered skin, mucosal and gut microbial colonisation, contribute to the increased risk of infection. Vaccination is important in people with diabetes although the efficacy of certain immunisations may be compromised, particularly in the presence of hyperglycaemia. The principles of treatment largely follow those of the general population with certain notable exceptions.

Efficacy of Self-Review of Lifestyle Behaviors with Once-Weekly Glycated Albumin Measurement in People with Type 2 Diabetes: A Randomized Pilot Study

INTRODUCTION

Lifestyle management, including appropriate modifications of nutrition, exercise, and medication behaviors, is essential for optimal glycemic control. The absence of appropriate monitoring methods to validate the lifestyle change may hinder the modification and continuation of behaviors. In this study, we evaluated whether once-weekly glycated albumin (GA) measurement received via a smartphone application could improve glycemia management in patients with type 2 diabetes mellitus by supporting self-review and modification of lifestyle behaviors.

METHODS

This open-label, randomized controlled, single-center study in Japan with an 8-week intervention period was conducted in individuals with type 2 diabetes mellitus and HbA1c levels between 7.0 and 9.0% (53‒75 mmol/mol). The intervention was once-weekly home monitoring of GA with a daily self-review of lifestyle behaviors using a smartphone application, in addition to conventional treatment.

RESULTS

A total of 98 participants (72.0% males; age 63.2 ± 11.4 years; HbA1c 7.39 ± 0.39% [57.3 ± 4.3 mmol/mol]) were randomly assigned to the intervention or control group. Significant decreases of the GA and HbA1c levels from the baseline to the last observation day were observed in the intervention group (- 1.71 ± 1.37% [- 39.1 ± 31.3 mmol/mol] and - 0.32 ± 0.32% [- 3.5 ± 3.5 mmol/mol], respectively). Significant decreases of the body weight, waist circumference, and caloric expenditure (p < 0.0001 and p = 0.0003, p = 0.0346, respectively), but not of the caloric intake (p = 0.678), were also observed in the intervention group as compared with the control group.

CONCLUSIONS

Self-review of lifestyle behaviors in combination with once-weekly GA home testing received via a smartphone application might potentially benefit glycemic management in people with type 2 diabetes mellitus.

Empagliflozin and Dapagliflozin Improve Endothelial Function in Mexican Patients with Type 2 Diabetes Mellitus: A Double-Blind Clinical Trial

AIM

To assess the acute effect of empagliflozin versus dapagliflozin administration on flow-mediated vasodilation in patients with type 2 diabetes mellitus.

DESIGN

A double-blind clinical trial, at the Experimental and Clinical Therapeutics Institute, University Health Sciences Center, at the Universidad de Guadalajara, in inpatients with T2D according to the 2023 ADA criteria.

METHODS

Thirty patients (15 males and 15 females), aged between 35 and 65 years, were included in this study, according to the 2023 ADA criteria. The eligible patients were randomly assigned to three groups: empagliflozin 25 mg once daily, dapagliflozin 10 mg once daily, or placebo once daily. Anthropometric parameters were taken using validated techniques. FMD was measured using a high-resolution semiautomatic ultrasound UNEX-EF 38G (UNEX Co., Ltd., Nagoya, Japan). Arterial tension was determined with the OMRON electronic digital sphygmomanometer (HEM 907 XL, Kyoto, Japan).

RESULTS

The group of patients who received empagliflozin had a significantly lower baseline flow-mediated dilation (FMD) compared to the group receiving dapagliflozin (p = 0.017); at the end of this study, the empagliflozin group achieved a comparable FMD to the dapagliflozin group (p = 0.88).

CONCLUSION

After the treatment period, the empagliflozin and dapagliflozin groups achieved similar FMD, suggesting a class effect.

Prevalence and co-prevalence of comorbidities among Chinese adult patients with type 2 diabetes mellitus: a cross-sectional, multicenter, retrospective, observational study based on 3B study database

Purpose

This study aimed to investigate the prevalence and co-prevalence of comorbidities among Chinese individuals with type 2 diabetes (T2DM).

Methods

Medical records were retrospectively retrieved from the 3B Study database, which provided a comprehensive assessment of comorbid conditions in Chinese adult outpatients with T2DM. Patient characteristics, laboratory measures, and comorbidities were summarized via descriptive analyses, overall and by subgroups of age (<65, 65-74, 75 years) and gender.

Results

Among 25,454 eligible patients, 53% were female, and the median age was 63 years. The median time of diabetes duration was 6.18 years. A total of 20,309 (79.8%) patients had at least one comorbid condition alongside T2DM. The prevalence of patients with one, two, three, and four or more comorbid conditions was 28.0%, 24.6%, 15.6%, and 11.6%, respectively. Comorbidity burden increased with longer T2DM duration. Older age groups also exhibited higher comorbidity burden. Females with T2DM had a higher overall percentage of comorbidities compared to males (42.7% vs. 37.1%). The most common comorbid conditions in T2DM patients were hypertension (HTN) in 59.9%, overweight/obesity in 58.3%, hyperlipidemia in 42.0%, retinopathy in 16.5%, neuropathy in 15.2%, cardiovascular disease (CVD) in 14.9%, and renal disease in 14.4%. The highest co-prevalence was observed for overweight/obesity and HTN (37.6%), followed by HTN and hyperlipidemia (29.8%), overweight/obesity and hyperlipidemia (27.3%), HTN and CVD (12.6%), HTN and retinopathy (12.1%), and HTN and renal disease (11.3%).

Conclusion

The majority of T2DM patients exhibit multiple comorbidities. Considering the presence of multimorbidity is crucial in clinical decision-making.

Diabetes and Hearing Impairment: Knowledge, Attitudes, and Practices Among Providers and Patients

PURPOSE

The purpose of this study was to assess the knowledge, attitudes, and practices among providers and patients regarding hearing impairment and screening referrals in people with diabetes.

METHODS

A cross-sectional survey design among health care providers and patients at an academic medical center in Oklahoma was used to gather knowledge, attitudes, and practices data.

RESULTS

Only 25.6% of providers selected hearing impairment as a complication of diabetes, whereas 96.7% selected retinopathy, kidney dysfunction, and foot infection. Reported barriers to referring patients for hearing impairment screenings were being unfamiliar with recommended screening frequency (57.3%) and existence of higher priorities (35.4%). When asked to select parts of the body affected by diabetes, 21.0% of patients surveyed selected ears, 88.0% selected feet, and 85.0% selected eyes and kidneys. Fewer patients reported being told hearing impairment is a complication of diabetes compared to retinopathy (8.1% vs 85.9%). Additionally, 24.2% of patients reported having a hearing impairment screening, and 96.0% reported having a dilated eye exam.

CONCLUSIONS

Most providers and patients at an academic medical center are unaware of the relationship between diabetes and hearing impairment. Providers reported there are several barriers that need to be overcome to refer patients to audiologists.

Expert Consensus on Dipeptidyl Peptidase-4 Inhibitor-Based Therapies in the Modern Era of Type 2 Diabetes Mellitus Management in India

India has a high prevalence of type 2 diabetes mellitus (T2DM) with unique clinical characteristics compared to other populations. Despite advancements in diabetes therapy, a significant number of patients in India still experience poor glycemic control and complications. Dipeptidyl peptidase-4 (DPP-4) inhibitors continue to be an important component of T2DM treatment due to their favorable efficacy and tolerability profile. Given the current scenario, there is a need to revisit the role of DPP-4 inhibitors in T2DM management in Indian patients. This consensus paper aims to provide guidance on the utilization of DPP-4 inhibitors in T2DM management from an Indian perspective. A consensus group of 100 experts developed recommendations based on an extensive literature review and discussions. The expert group emphasized the importance of timely glycemic control, combination therapy, and targeting the underlying pathophysiology of T2DM. The combinations of DPP-4 inhibitors with metformin and/or sodium-glucose transport protein-2 inhibitors are rationalized in this paper, considering their complementary mechanisms of action. This paper provides valuable insights for clinicians in optimizing the management of T2DM in the Indian population with the use of DPP-4 inhibitors and proposes an algorithm for selecting DPP-4 inhibitor-based therapies.

Epidemiology, screening, and co-management of type 2 diabetes mellitus and metabolic dysfunction-associated steatotic liver disease

Metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as NAFLD, is increasingly recognized as a prevalent global burden. Type 2 diabetes mellitus (T2DM), another important metabolic disease, is considered a major contributor to the development of MASLD. MASLD and T2DM have a strong association with each other due to shared pathogenic mechanisms. The co-existence of the 2 diseases increases the risk of liver-related adverse outcomes and imposes a heavier burden on extrahepatic outcomes, representing a substantial public health issue. Effective assessment and management of T2DM combined with MASLD necessitate a multidisciplinary approach. The emergence of numerous RCTs has shed light on the treatment of T2DM combined with MASLD. This review uncovers the epidemiology of the intertwined T2DM and MASLD, offers insights into the evaluation of hepatic fibrosis in patients with T2DM, glucose monitoring in the MASLD population, and provides comprehensive co-management strategies for addressing both diseases.

Liver and cardiovascular disease outcomes in metabolic syndrome and diabetic populations: Bi-directional opportunities to multiply preventive strategies

The incidence and prevalence of metabolic syndrome (MetS) and type 2 diabetes mellitus (T2DM) are rising globally. MetS and T2DM are associated with significant morbidity and mortality, which is partly related to liver and cardiovascular disease. Insulin resistance is central to MetS and T2DM pathophysiology, and drives ectopic fat deposition in the liver, also known as metabolic dysfunction-associated steatotic liver disease (MASLD). MetS and T2DM are not only risk factors for developing MASLD but are also independently associated with disease progression to steatohepatitis, cirrhosis, and hepatocellular carcinoma. In addition to the risk of liver disease, MetS and T2DM are independent risk factors for cardiovascular disease (CVD), including coronary artery disease (CAD) and heart failure (HF). Importantly, there is a bidirectional relationship between liver and CVD due to shared disease pathophysiology in patients with MetS and T2DM. In this review, we have described studies exploring the relationship of MetS and T2DM with MASLD and CVD, independently. Following this we discuss studies evaluating the interplay between liver and cardiovascular risk as well as pragmatic risk mitigation strategies in this patient population.

Prevalence of nonalcoholic fatty liver disease and liver cirrhosis in Chinese adults with type 2 diabetes mellitus

BACKGROUND

Nonalcoholic fatty liver disease (NAFLD) and liver cirrhosis are significant clinical concerns, especially among individuals with type 2 diabetes mellitus (T2DM). However, in China, there is a paucity of reliable evidence detailing the characteristics of NAFLD and liver cirrhosis in T2DM. Furthermore, the relationship between blood glucose levels and NAFLD prevalence remains unclear.

METHODS

Data from the Shanghai Suburban Adult Cohort and Biobank were analyzed, including 6621 participants with T2DM. NAFLD was diagnosed by ultrasonography and liver cirrhosis was performed according to the health information systems. Logistic regression and restricted cubic spline analysis were used to explore the potential risk factors for NAFLD and liver cirrhosis.

RESULTS

The prevalence of NAFLD was 59.36%, and liver cirrhosis was 1.43% among T2DM patients. In these patients, factors like age, being female, marital status, and obesity significantly increased the risk of NAFLD. Specifically, obesity had a strong positive association with NAFLD (odds ratio [OR] = 4.70, 95% confidence interval [CI]: 4.13-5.34). The higher glycated hemoglobin (HbA1c) quartile was associated with a heightened NAFLD risk compared to the lowest quartile (all p < .001). The HbA1c-NAFLD relationship displayed a linear that mimicked an inverted L-shaped pattern. A significant positive association existed between HbA1c levels and NAFLD for HbA1c <8.00% (OR = 1.59, 95% CI: 1.44-1.75), but this was not observed for HbA1c >8.00% (OR = 1.03, 95% CI: 0.92-1.15).

CONCLUSION

Systematic screening for NAFLD is essential in T2DM patients, especially with poor glucose control and obesity in female.

Elevated ITGA1 levels in type 2 diabetes: implications for cardiac function impairment

AIMS/HYPOTHESIS

Type 2 diabetes mellitus is known to contribute to the development of heart failure with preserved ejection fraction (HFpEF). However, identifying HFpEF in individuals with type 2 diabetes early on is often challenging due to a limited array of biomarkers. This study aims to investigate specific biomarkers associated with the progression of HFpEF in individuals with type 2 diabetes, for the purpose of enabling early detection and more effective management strategies.

METHODS

Blood samples were collected from individuals with type 2 diabetes, both with and without HFpEF, for proteomic analysis. Plasma integrin α1 (ITGA1) levels were measured and compared between the two groups. Participants were further categorised based on ITGA1 levels and underwent detailed transthoracic echocardiography at baseline and during a median follow-up period of 30 months. Multivariable linear and Cox regression analyses were conducted separately to assess the associations between plasma ITGA1 levels and changes in echocardiography indicators and re-hospitalisation risk. Additionally, proteomic data for the individuals' left ventricles, from ProteomeXchange database, were analysed to uncover mechanisms underlying the change in ITGA1 levels in HFpEF.

RESULTS

Individuals with type 2 diabetes and HFpEF showed significantly higher plasma ITGA1 levels than the individuals with type 2 diabetes without HFpEF. These elevated ITGA1 levels were associated with left ventricular remodelling and impaired diastolic function. Furthermore, during a median follow-up of 30 months, multivariable analysis revealed that elevated ITGA1 levels independently correlated with deterioration of both diastolic and systolic cardiac functions. Additionally, higher baseline plasma ITGA1 levels independently predicted re-hospitalisation risk (HR 2.331 [95% CI 1.387, 3.917], p=0.001). Proteomic analysis of left ventricular myocardial tissue provided insights into the impact of increased ITGA1 levels on cardiac fibrosis-related pathways and the contribution made by these changes to the development and progression of HFpEF.

CONCLUSIONS/INTERPRETATION

ITGA1 serves as a biomarker for monitoring cardiac structural and functional damage, can be used to accurately diagnose the presence of HFpEF, and can be used to predict potential deterioration in cardiac structure and function as well as re-hospitalisation for individuals with type 2 diabetes. Its measurement holds promise for facilitating risk stratification and early intervention to mitigate the adverse cardiovascular effects associated with diabetes.

DATA AVAILABILITY

The proteomic data of left ventricular myocardial tissue from individuals with type 2 diabetes, encompassing both those with and without HFpEF, is available from the ProteomeXchange database at http://proteomecentral.proteomexchange.org .

Effect of arsenic on the risk of gestational diabetes mellitus: a systematic review and meta-analysis

BACKGROUND

Gestational diabetes mellitus (GDM) is a complication of pregnancy associated with numerous adverse outcomes. There may be a potential link between GDM and arsenic (As) exposure, but this hypothesis remains controversial. This meta-analysis summarizes the latest studies evaluating the association between As and GDM.

METHODS

A comprehensive search of the PubMed, Embase, and Scopus databases up to September 2023 was performed. The pooled estimates with 95% CIs were presented using forest plots. Estimates were calculated with random effects models, and subgroup and sensitivity analyses were conducted to address heterogeneity.

RESULTS

A total of 13 eligible studies involving 2575 patients with GDM were included in this meta-analysis. The results showed that women exposed to As had a significantly increased risk of GDM (OR 1.47, 95% CI: 1.11 to 1.95, P = 0.007). Subgroup analyses suggested that the heterogeneity might be attributed to the years of publication. In addition, sensitivity analysis confirmed the robust and reliable results.

CONCLUSIONS

This analysis suggested that women exposed to As have a greater risk of GDM. However, the significant heterogeneity across studies requires careful interpretation.

Glucose Color Index: Development and Validation of a Novel Measure of the Shape of Glycemic Variability

BACKGROUND

Standard continuous glucose monitoring (CGM) metrics: mean glucose, standard deviation, coefficient of variation, and time in range, fail to capture the shape of variability in the CGM time series. This information could facilitate improved diabetes management.

METHODS

We analyzed CGM data from 141 adults with type 2 diabetes in the Hyperglycemic Profiles in Obstructive Sleep Apnea (HYPNOS) trial. Participants in HYPNOS wore CGM sensors for up to two weeks at two time points, three months apart. We calculated the log-periodogram for each time period, summarizing using disjoint linear models. These summaries were combined into a single value, termed the Glucose Color Index (GCI), using canonical correlation analysis. We compared the between-wear correlation of GCI with those of standard CGM metrics and assessed associations between GCI and diabetes comorbidities in 398 older adults with type 2 diabetes from the Atherosclerosis Risk in Communities (ARIC) study.

RESULTS

The GCI achieved a test-retest correlation of R = .75. Adjusting for standard CGM metrics, the GCI test-retest correlation was R = .55. Glucose Color Index was significantly associated (p < .05) with impaired physical functioning, frailty/pre-frailty, cardiovascular disease, chronic kidney disease, and dementia/mild cognitive impairment after adjustment for confounders.

CONCLUSION

We developed and validated the GCI, a novel CGM metric that captures the shape of glucose variability using the periodogram signal decomposition. Glucose Color Index was reliable within participants over a three-month period and associated with diabetes comorbidities. The GCI suggests a promising avenue toward the development of CGM metrics which more fully incorporate time series information.

Diagnosing Osteoporosis in Diabetes-A Systematic Review on BMD and Fractures

PURPOSE OF REVIEW

Recently, the American Diabetes Association updated the 2024 guidelines for Standards of Care in Diabetes and recommend that a T-score of - 2.0 in patients with diabetes should be interpreted as equivalent to - 2.5 in people without diabetes. We aimed to evaluate the most recent findings concerning the bone mineral density (BMD)-derived T-score and risk of fractures related to osteoporosis in subjects with diabetes.

RECENT FINDINGS

The dual-energy X-ray absorptiometry (DXA) scan is the golden standard for evaluating BMD. The BMD-derived T-score is central to fracture prediction and signifies both diagnosis and treatment for osteoporosis. However, the increased fracture risk in diabetes is not sufficiently explained by the T-score, complicating the identification and management of fracture risk in these patients. Recent findings agree that subjects with type 2 diabetes (T2D) have a higher T-score and higher fracture risk compared with subjects without diabetes. However, the actual number of studies evaluating the direct association of higher fracture risk at higher T-score levels is scant. Some studies support the adjustment based on the 0.5 BMD T-score difference between subjects with T2D and subjects without diabetes. However, further data from longitudinal studies is warranted to validate if the T-score treatment threshold necessitates modification to prevent fractures in subjects with diabetes.

Guideline-based management of metabolic dysfunction-associated steatotic liver disease in the primary care setting

BACKGROUND

The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) is increasing worldwide. Primary care providers play a critical role in the screening, diagnosis, and management of MASLD and/or metabolic dysfunction-associated steatohepatitis (MASH), though they can face challenges in this setting, particularly where healthcare resources are limited and barriers to care exist. To address these challenges, several guidelines have been developed to provide evidence-based recommendations for the clinical assessment and management of patients with MASLD/MASH.

AIMS

To provide a unified, simple-to-understand, practical guide for MASLD screening, diagnosis, and management based on current guideline recommendations, for use by primary care providers in daily practice.

METHODS

Evidence-based recommendations from several international guidelines were summarized, focusing on the similarities and differences between them.

RESULTS

Recommendations are broadly aligned across the guidelines, but several key differences are evident. Practical guidance is provided on screening, identifying target populations for risk stratification, initial evaluation of individuals with suspected MASLD, surveillance, risk stratification and referral, as well as approaches to the management of MASLD and associated comorbidities, with specific considerations for the primary care setting.

CONCLUSIONS

Primary care providers are ideally placed to identify at-risk individuals, implement evidence-based interventions to prevent the development of fibrosis and cirrhosis, and effectively manage comorbidities. Equipping primary care providers with the necessary knowledge and tools to effectively manage MASLD/MASH may help to improve patient outcomes and reduce the burden of liver disease.

Efficacy and safety of tirzepatide in people with type 2 diabetes by baseline body mass index: An exploratory subgroup analysis of SURPASS-AP-Combo

AIMS

To assess the efficacy and safety of tirzepatide versus insulin glargine in people with type 2 diabetes (T2D) by baseline body mass index (BMI).

MATERIALS AND METHODS

Participants with T2D from the Phase 3 SURPASS-AP-Combo trial (NCT04093752) were categorized into three BMI subgroups (normal weight [<25 kg/m2 ], overweight [≥25 and <30 kg/m2 ], and obese [≥30 kg/m2 ]) according to World Health Organization criteria. Exploratory outcomes including glycaemic control, body weight, cardiometabolic risk, and safety were compared among three tirzepatide doses (5, 10 or 15 mg) and insulin glargine.

RESULTS

Of 907 participants, 235 (25.9%) had a BMI <25 kg/m2 , 458 (50.5%) a BMI ≥25 to <30 kg/m2 , and 214 (23.6%) a BMI ≥30 kg/m2 at baseline. At Week 40, all tirzepatide doses led to a greater reduction in mean glycated haemoglobin (HbA1c; -2.0% to -2.8% vs. -0.8% to -1.0%, respectively) and percent change in body weight (-5.5% to -10.8% vs. 1.0% to 2.5%, respectively) versus insulin glargine, across the BMI subgroups. Compared with insulin glargine, a higher proportion of tirzepatide-treated participants achieved treatment goals for HbA1c and body weight reduction. Improvements in other cardiometabolic indicators were also observed with tirzepatide across all the BMI subgroups. The safety profile of tirzepatide was similar across all subgroups by BMI. The most frequent adverse events with tirzepatide were gastrointestinal-related events and decreased appetite, with relatively few events leading to treatment discontinuation.

CONCLUSIONS

In participants with T2D, regardless of baseline BMI, treatment with tirzepatide resulted in statistically significant and clinically meaningful glycaemic reductions and body weight reductions compared with insulin glargine, with a safety profile consistent with previous reports.

Optimal ALT threshold for the automated diagnosis of MASLD: A population-based study using iLFT

INTRODUCTION AND OBJECTIVES

Early diagnosis of metabolic dysfunction-associated steatotic liver disease (MASLD), especially with advanced fibrosis, is crucial due to the increased risk of complications and mortality. Serum alanine aminotransferase (ALT) is commonly used; however, many patients have normal ranges (<55 U/L) who may remain undetected. We investigated the clinical implications of a lower ALT cut-off (>30 U/L) using intelligent liver function testing (iLFT) to identify MASLD patients with and without advanced fibrosis in primary care.

MATERIALS AND METHODS

All patients entering the iLFT diagnostic pathway had liver aetiological screening investigations if ALT >30 U/L. In those with MASLD the proportions with and without advanced fibrosis at different ALT thresholds: 31-41 U/L, 42-54 U/L and ≥55 U/L were compared.

RESULTS

16,373 patients underwent iLFT between March 2016 to April 2022. 762 (5 %) patients had MASLD with abnormal fibrosis scores, while 908 (6 %) had MASLD with normal fibrosis scores. 428 (56 %) patients were assessed in liver clinics, where 169 (39 %) had evidence of fibrosis. Of these, 22 (13 %) had ALT 31-41 U/L, 31 (18 %) had ALT 42-54 U/L and 116 (69 %) had ALT ≥55 U/L. 145 (86 %) patients had advanced fibrosis or cirrhosis, where 20 (14 %) had ALT 31-41 U/L, 28 (19 %) had ALT 42-54 U/L and 97 (67 %) had ALT ≥55 U/L.

CONCLUSIONS

33 % of MASLD patients with advanced fibrosis or cirrhosis had ALT 31-54 U/L, who would have been missed using the conventional ALT range. This suggests that lowering the ALT cut-off improves diagnosis of MASLD with advanced fibrosis in primary care.

Serum thrombospondin-2 level changes with liver stiffness improvement in patients with type 2 diabetes

OBJECTIVE

Baseline circulating thrombospondin-2 (TSP2) level was identified as a potential novel hepatic fibrosis biomarker that associates with development and progression of hepatic fibrosis in patients with nonalcoholic fatty liver disease and type 2 diabetes. Here, we investigated whether circulating TSP2 levels changed with improvement in liver stiffness (LS), which reflects liver fibrosis on transient elastography.

DESIGN

Serum TSP2 levels were measured in participants from a randomized, open-label intervention study, at baseline and after 24-weeks treatment of either dapagliflozin 10 mg (N = 30) or sitagliptin 100 mg daily (N = 30). Vibration-controlled transient elastography was performed to evaluate the severity of hepatic fibrosis and steatosis using LS and controlled attenuation parameter (CAP), respectively.

PATIENTS AND MEASUREMENTS

Among all 60 participants with similar clinical characteristics at baseline (mean HbA1c 8.9%, CAP 289 dB/m and LS 5.8 kPa), despite similar HbA1c lowering, treatment with dapagliflozin, but not sitagliptin, led to significant improvements in body weight (BW) (p = .012), CAP (p = .015) and LS (p = .011) after 24 weeks.

RESULTS

Serum TSP2 level decreased significantly from baseline in dapagliflozin-treated participants (p = .035), whereas no significant change was observed with sitagliptin. In correlation analysis, change in serum TSP2 levels only positively correlated with change in LS (r = .487, p = .006), but not with changes in BW, CAP or HbA1c after dapagliflozin treatment.

CONCLUSIONS

Serum TSP2 level decreased with LS after dapagliflozin treatment, and was independent of improvements in BW, glycemic control and hepatic steatosis, further supporting the potential of serum TSP2 level as a novel hepatic fibrosis biomarker in type 2 diabetes.

Targeting metabolic-associated fatty liver disease in diabetic kidney disease: A call to action

Nonalcoholic fatty liver disease or metabolic-associated fatty liver disease (MAFLD) is a common condicion with increasing prevalence and incidence, specially in patients with type 2 diabetes mellitus (T2DM). Both cardiovascular and renal disease are clearly increased in these patients, particularly in those with diabetic nephropathy. In the liver-heart-kidney-metabolic axis, the common pathophysiological basis of MAFLD, cardiovascular disease (CVD), chronic kidney disease (CKD), and T2DM is the same. The clinical relationship between all of them is clear and is multidirectional: MAFLD may precede the development of cardiovascular and renal disease, and may also worsen the prognosis of these complications once developed. In this review we emphasize the importance of targeting MAFLD in Diabetic kidney disease, with the goal of detecting high-risk patients in order to improve their prognosis.
