Objective: Inflammation contributes to the development of type 2 diabetes mellitus (T2DM). While South Asians are more prone to develop T2DM than Europids, the inflammatory phenotype of the South Asian population remains relatively unknown. Therefore, we aimed to investigate potential differences in circulating levels of inflammation-related proteins in South Asians compared to Europids with T2DM.

Article Synopsis
  • The study investigates whether liraglutide, a GLP-1R agonist used for weight loss in type 2 diabetes patients, affects plasma levels of growth differentiation factor 15 (GDF15), which is known to suppress appetite.
  • Despite weight loss observed in patients treated with liraglutide, their plasma GDF15 levels remained unchanged after 26 weeks of treatment, regardless of ethnicity (Dutch South Asians vs. Dutch Europids).
  • The findings suggest that the weight loss effects of liraglutide are likely due to mechanisms other than GDF15, as no correlation was found between changes in GDF15 levels and weight or metformin dosage.

Mutations in the -gene can cause a variety of 'laminopathies'. These laminopathies are associated with a range of phenotypes, including disorders affecting the adipose tissue, peripheral nerves, the heart, such as dilated cardiomyopathy and conduction system abnormalities, and less commonly, progeroid disorders. This case series describes two families in which two novel LMNA-gene variants were identified, and who presented with an atypical progeroid phenotype with primarily premature aortic and mitral valve stenosis.

Type 2 diabetes mellitus (T2DM) poses a higher risk for complications in South Asian individuals compared to other ethnic groups. To shed light on potential mediating factors, we investigated lipidomic changes in plasma of Dutch South Asians (DSA) and Dutch white Caucasians (DwC) with and without T2DM and explore their associations with clinical features. Using a targeted quantitative lipidomics platform, monitoring over 1000 lipids across 17 classes, along with H NMR based lipoprotein analysis, we studied 51 healthy participants (21 DSA, 30 DwC) and 92 T2DM patients (47 DSA, 45 DwC) from the etic resonance ssessment of za efficacy in the egression of cardiovascular dysfunction in type 2 dbetes mellitus (MAGNA VICTORIA) study.

Background: Ethnic differences in the progression and outcome of diabetic kidney disease (DKD) remain to be elucidated. MRI-quantified renal sinus fat volume could be a potential biomarker to help investigate the changes of DKD risk in response to glucose regulation.

Purpose: To evaluate whether the effect of glucose-lowering treatment on renal sinus fat volume differed in West Europeans (WE) compared to South Asians (SA), and whether ethnic-related difference exists regarding the effect of liraglutide on renal sinus fat.

Article Synopsis
  • The study explores how the composition of high-density lipoproteins (HDL) relates to microvascular complications in individuals with type 2 diabetes, particularly focusing on Dutch South Asian (DSA) versus Dutch white Caucasian (DwC) populations.
  • Researchers used advanced techniques to analyze HDL in 51 healthy and 92 diabetic participants, finding significant differences in HDL composition between the groups, especially in apolipoprotein A2 and HDL-4 levels.
  • Lower levels of HDL-4 in DSA individuals with diabetes were linked to higher risks of microvascular complications, suggesting that HDL composition could serve as an ethnicity-specific biomarker for tracking diabetes-related health risks.

Objective: Ectopic lipid accumulation in the kidney (fatty kidney) is a potential driver of diabetic kidney disease, and tight glycemic control can reduce risk of diabetic nephropathy. We assessed whether glycemic control influences renal triglyceride content (RTGC). Furthermore, we compared glucagon-like peptide-1 receptor agonist liraglutide versus standard glucose-lowering therapy.

Aims/hypothesis: Brown adipose tissue (BAT) improves energy metabolism by combusting glucose and lipids into heat. Agonism of the glucagon-like peptide-1 receptor (GLP-1R) within the central nervous system activates BAT in mice. Moreover, in patients with type 2 diabetes, GLP-1R agonism lowers body weight and improves glucose and lipid levels, possibly involving BAT activation.

Cholesteryl ester transfer protein (CETP) is mainly expressed by Kupffer cells in the liver. A reduction of hepatic triglyceride content (HTGC) by pioglitazone or caloric restriction is accompanied by a decrease in circulating CETP. Since GLP-1 analogues also reduce HTGC, we assessed whether liraglutide decreases CETP.

Aims/hypothesis: Individuals of South Asian origin are at increased risk of developing type 2 diabetes mellitus and associated comorbidities compared with Europids. Disturbances in energy metabolism may contribute to this increased risk. Skeletal muscle and possibly also brown adipose tissue (BAT) are involved in human energy metabolism and nitric oxide (NO) is suggested to play a pivotal role in regulating mitochondrial biogenesis in both tissues.
