Dear Editor,I read the article by Wang et al., who conducted a meta-analysis to investigate the association between serum irisin levels and diabetic nephropathy (DN) in patients with type 2 diabetes mellitus (T2DM) 1. The mean serum irisin level in T2DM patients with microalbuminuria was significantly lower than that in T2DM patients with normoalbuminuria. In addition, the mean serum irisin level in T2DM patients with macroalbuminuria was significantly lower than that in T2DM patients with microalbuminuria. Furthermore, the mean serum irisin level in T2DM patients with estimated glomerular infiltration rate (eGFR)<60 ml/min 1.73 m2 was significantly lower than that in T2DM patients with eGFR≥60 ml/min 1.73 m2. The authors concluded that decreased serum irisin level was associated with albuminuria and reduced eGFR in T2DM patients. DN was significantly related to decreased serum irisin level in T2DM patients with dose-response manner. Progression of DN may be considered as advanced DM status, and serum irisin level would reflect glucose intolerance via insulin resistance. I have a comment about their study with special reference to the fundamental relationship between the types of DM and serum irisin levels.

Telomere Biology

BACKGROUND: Insulin resistance accelerates the aging process, but its speed depends on the individual characteristics of the metabolism. One of the reasons for the different aging rates in individuals with insulin resistance is the initially different “genetic protection” of cells, which many scientists associate with replicative cellular aging.AIMS: to study the relationship between the state of carbohydrate metabolism and markers of replicative cell aging in individuals with different sensitivity to insulin.MATERIALS AND METHODS: The observation study included 305 patients. The parameters of glucose metabolism and telomere biology were studied.RESULTS: The mean age of the patients was 51.5±13.3 years. Patients were divided into three groups depending on presence of insulin resistance: healthy, with insulin resistance and with type 2 diabetes. The mean age of healthy patients was 48.82±13.87 years, in insulin resistance group — 53.04±12.8, in 2 diabetes mellitus — 58.4±7.90. The median telomere length was 9.76. The median telomerase activity was 0.48. Both telomere length and telomerase activity progressively decrease as insulin resistance increases. In patients with diabetes, short telomere lengths and low telomerase activity predominated. The insulin resistance index has the greatest impact on the risk of detecting “short” telomeres. In patients with insulin resistance, an increase in glycated hemoglobin increases the likelihood of detecting short telomeres by 2.4 times, and in diabetes mellitus by 4.26 times, an increase in fasting plasma glucose by 90%, and an increase in HOMA-IR by 35%. An increase in insulin resistance increases the risk of detecting «low» telomerase activity by 53% and the risk of detecting «very low» telomerase activity by 92%. A decrease in synsulin resistance increases the chance of increasing telomerase activity to «very high» by 51%.CONCLUSION: Shorter telomeres are associated with more pronounced disorders of carbohydrate metabolism and a higher degree of insulin resistance. Further studies of metabolic status are necessary to personalize their lifestyle and treatment goals.

The Relationship

In the current study, the development of diabetic nephropathy identified the relationship between the polymeric marker of AC genes and the NS3 gene. One hundred twenty-nine patients with type 2 diabetes were tried. Patients in the principle gathering: 65 people with diabetes nephropathy preserved kidney function (33 patients), and kidney function weakness (32 patients), 64 patients with Diabetes were enduring more than 10-20 years, diabetic nephropathy preserved the chain of genotyping polymers carries out kidney function (31 patients). The study showed a link between eNOS3 genes in the development of diabetic nephropathy in Type 2 diabetes patients, supported by the ACE gene.

AbstractIrisin, an emerging adipokine, has been involved in the pathogenesis of type 2 diabetes mellitus (T2DM). However, previous studies evaluating the association between irisin and diabetic nephropathy (DN) showed inconsistent results. We performed a meta-analysis to evaluate the above association. Matched case-control studies evaluating the difference of serum irisin between T2DM patients with and without DN were identified via systematic search of PubMed, Embase, Cochranes’ Library, China National Knowledge Infrastructure, and WanFang databases from inception to December 5, 2020. A random-effects model or a fixed-effects model was used to pool the results according to the heterogeneity. Overall, thirteen matched case-control studies including 1735 T2DM patients were included. Results of meta-analysis showed that compared to T2DM patients with normoalbuminuria, those with microalbuminuria [10 studies, standard mean difference (SMD): 1.12, 95% confidence interval (CI): 0.48–1.77, p<0.001; I2=94%] and macroalbuminuria (10 studies, SMD: 1.86, 95% CI: 0.93–2.79, p<0.001; I2=97%) had significantly lower serum irisin. Besides, the serum level of irisin was significantly lower in T2DM patients with macroalbuminuria than those with microalbuminuria (10 studies, SMD: 0.91, 95% CI: 0.44–1.38, p<0.001; I2=90%). In addition, patients with estimated glomerular infiltration rate (eGFR)<60 ml/min 1.73 m2 had lower serum irisin compared to those with eGFR≥60 ml/min 1.73 m2 (4 studies, SMD: 0.89, 95% CI: 0.32–1.46, p=0.002; I2=91%). In conclusion, serum irisin may be associated with albuminuria and reduced eGFR in T2DM patients.

The Mean

Objectives. To evaluate body mass index standard deviation score (BMI-SDS), insulin sensitivity, and progression to type 2 diabetes mellitus (T2DM) in children at risk for T2DM approximately 3 years after being diagnosed with overweight/obesity and insulin resistance (measured by Homeostasis Model Assessment of Insulin Resistance [HOMA-IR]). Methods. Out of 86 invited children, 44 (mean age 15.4 ± 3.6 years) participated. Medical history, physical examination, and laboratory workup were performed. Results. While the mean BMI-SDS significantly increased from 2.9 to 3.4, the mean HOMA-IR significantly decreased from 5.5 to 4.6 (baseline vs follow-up visit). Change in HOMA-IR was only due to a decrease in mean fasting plasma insulin (24.1 vs 21.1, P = .073). Conclusions. Although increase in BMI-SDS in these children is worrisome, the American Diabetes Association recommended screening interval of 3 years for children at risk for T2DM is not too long based on the fact that none of our study participants developed T2DM.

Patients With Diabetes

Before a patient develops overt type 2 diabetes mellitus, there is typically a prolonged period of patho-physiological change. In the common form of type 2 diabetes mellitus, there are years of insulin resistance, initially compensated by increased beta cell function, then impaired glucose tolerance develops, and finally type 2 diabetes. We know from studies such as the United Kingdom Prospective Diabetes Study (UKPDS) and the Belfast study that loss of beta cell function and insulin resistance are usually relentless.1, 2 Thus, therapy to reduce blood glucose has to be gradually increased with time for patients with diabetes. What is less well known is that every person has a different slope for beta cell function loss which intersects with insulin resistance.
