Background: Carotid atherosclerosis (CAS) is a common manifestation of macroangiopathy in type 2 diabetes mellitus (T2DM). C1Q/TNF-related protein 4 (CTRP4) was found to be involved in regulation of food intake behaviors and glucolipid metabolism, which were also key factors in the development of CAS. However, the relationship between serum CTRP4 and CAS in T2DM remains unclear.

Methods: A total of 111 participants with T2DM were enrolled in the study and were divided into 2 groups (T2DM group and T2DM + CAS group) according to the result of carotid ultrasound examinations. Serum CTRP4 levels were measured by enzyme linked immunosorbent assay (ELISA). Trend χ test and binary stepwise logistic regression were conducted to assess the association between serum CTRP4 and the risk of CAS in T2DM.

Results: Serum CTRP4 concentrations in T2DM + CAS group were significantly lower compared with those in T2DM group [7.98 (5.53) vs. 11.29 (7.36) ng/ml, P < 0.01]. The risk of CAS in T2DM decreased with the increasing of CTRP4 quartiles (P for trend < 0.01). Binary stepwise logistic regression suggested that serum CTRP4 might be an independent influence factor for CAS in patients with T2DM (P < 0.01) and high concentrations of serum CTRP4 were related to low risk of CAS in T2DM.

Conclusions: The concentrations of serum CTRP4 are lower in T2DM patients with CAS compared to those without CAS. Serum CTRP4 levels are negatively related to the risk of CAS in T2DM.

Background: The adipokines secreted by adipocytes might play an important role through crossing the blood brain barrier to the brain, which could mediate the common physiological pathway between depression and obesity. CTRP4, a member of the CTRP family, is highly expressed in human adipose tissue and brain tissue.

Objective: this study aimed to measure serum C1q/TNF-related protein 4 (CTRP4) levels in depressive patients to explore the association between CTRP4 levels and depression.

Objective: We investigated the correlation between serum C1q/TNF-related protein 4 (CTRP4) level and flow-mediated dilation (FMD) in patients with type 2 diabetes mellitus (T2DM), and evaluated the biological effects of CTRP4 on human umbilical vein endothelial cells (HUVECs).

Methods: A group of 165 patients diagnosed with T2DM were included in this study. Endothelial function was measured with the examination of brachial artery FMD.

There is a strong bidirectional relationship between nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM), both of which can lead to an increase in harmful metabolism and cardiovascular risk. It was discovered that C1q/TNF-related protein 4 (CTRP4) regulates glucolipid metabolism and feeding behavior. However, the correlation between serum CTRP4 and NAFLD in T2DM patients is not yet fully understood.

Aims/introduction: To evaluate the correlation of circulating C1q tumor necrosis factor-related protein 4 (CTRP4) with coronary artery disease (CAD) in type 2 diabetes mellitus patients.

Methods: A total of 240 individuals with type 2 diabetes mellitus were enrolled in our center between January 2020 and December 2020. They were assigned into two groups, including the CAD and non-CAD groups, based on coronary angiography or computed tomography angiography findings.
