The level of the neudesin in type-2 diabetic patients and the relationship between the metabolic parameters and carotid intima-media thickness

BACKGROUND

Neudesin is a protein that is secreted from adipose tissue and central nervous system and has a regulatory function on energy metabolism. Although the effect of this protein is shown in the experimental model of type-2 diabetes mellitus (type-2DM), its effect in humans is not clearly known. In this study, we aimed to evaluate the relationship between serum neudesin level and metabolic, anthropometric and cardiovascular parameters in newly diagnosed type-2DM patients (group 1).

METHODS

Forty patients in each were included in our study for group 1 and for the control group (group 2), which consisted of age and sex-matched healthy subjects. Serum neudesin, hs-CRP, carotid intima media thickness (CIMT), Body Mass Index (BMI) and insulin resistance (HOMA-IR) levels were compared prospectively.

RESULTS

Serum neudesin levels were significantly higher in diabetic patients than in the control group (type-2DM: 64.69±3.06 ng/mL, control: 55.52±5.48 ng/mL, P=0.004*). There was an independent relationship between serum neudesin and HOMA-IR and BMI. Although there is a correlation between serum neudesin and CIMT; this feature disappeared in the regression analysis.

CONCLUSIONS

Serum neudesin increased in new diagnosis type-2DM patients. This increase seems to be related to obesity and insulin resistance. However, more extensive research is needed to clarify this issue.

Correlation of serum C1q-tumour necrosis factor-related protein 5 levels with metabolic parameters and carotid intima-media thickness in newly diagnosed type 2 diabetes mellitus patients

PURPOSE

Recent studies have shown that cytokines secreted from adipose tissues play a role in the pathogenesis of type 2 diabetes mellitus (T2DM). CTRP5 (C1q-TNF-related protein 5) is a novel adipokine that has been shown to be associated with glucose and lipid metabolism. Varying levels of CTRP5 have been reported in individuals with diabetes, obesity and coronary artery disease. The aim of this study was to examine serum levels of CTRP5 and to show the relationship with cardiometabolic parameters in T2DM patients.

METHOD

The study included 40 T2DM patients and 40 age- and sex-matched healthy control subjects. All the study participants were evaluated with respect to BMI, waist circumference, lipid profile, insulin resistance (HOMA-IR), serum CTRP5 levels, carotid intima-media thickness, and hs-CRP.

RESULTS

No statistically significant differences were found between the control group and the diabetic group in terms of age, sex, or BMI. Serum CTRP5 levels (T2DM = 94.55 ± 28.70 ng/ml, control = 76.02 ± 27.22 ng/ml, P = 0.004*) were significantly higher in the group of newly diagnosed diabetic patients. A positive correlation was found between CTRP5 and the cardiometabolic parameters of carotid intima-media thickness (CIMT), hs-CRP, HOMA-IR and BMI. Regression analysis results showed that CTRP5 levels were independently correlated with insulin resistance estimated by HOMA-IR.

CONCLUSION

Serum CTRP5 levels were correlated with cardiometabolic parameters and could therefore be a promising indicator of metabolic status and a possible biomarker of insulin resistance. However, the contradictory results reported in different studies indicate the need for further research to assess the significance of CTRP5 for diagnosis and monitoring of treatment efficacy.
