Int J Endocrinol 2021; 2021:9286492. [PMID: 34976052 PMCID: PMC8716211 DOI: 10.1155/2021/9286492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 11/15/2021] [Accepted: 12/08/2021] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Para and perirenal fat is a fat pad surrounding the kidneys. Recent studies showed the association between para and perirenal fat and cardiovascular diseases including atherosclerosis and hypertension. We aimed to assess the relationship between para-perirenal ultrasonographic fat thickness and serum high-density lipoprotein (HDL) level and cholesterol efflux capacity of HDL in patients with type 2 diabetes mellitus (T2DM). METHODS We recruited 58 subjects with T2DM and collected anthropometric indices including height, weight, waist circumference, and other clinical data. Para-perirenal ultrasonographic fat thickness (PUFT) was measured via ultrasound. Serum lipid profile and other metabolic indices were determined as well. Correlation analysis and regression analysis were performed to analyze the relationship between PUFT and HDL level and cholesterol efflux capacity in all patients and subgroups. RESULTS Patients with higher PUFT have lower serum HDL level but increased cholesterol efflux capacity. Further analysis showed that PUFT negatively correlated with the serum HDL level in all patients, with no difference in groups divided by body mass index (BMI). In addition, PUFT was positively correlated with cholesterol efflux capacity in all patients. Multiple stepwise regression analysis showed an independent association of PUFT and serum HDL level and cholesterol efflux capacity. CONCLUSIONS PUFT is closely correlated with the serum HDL level and cholesterol efflux capacity in patients with T2DM.

Clin Obes 2020; 10:e12404.

Abstract
The aim of this study was to evaluate the correlation between ultrasound measurements of visceral adipose tissue (VAT) in different locations and visceral fat area parameters estimated by computed tomography (CT), as well as to determine the cut-off values of ultrasound measurements in patients with metabolic syndrome and in normal controls. Altogether, 304 patients aged 18 to 65 years were enrolled in the study. Ultrasound measurements of visceral fat volume were performed using a number of already described techniques. The correlations of ultrasound indices of VAT and СТ (104 patients) ranged from 0.420 to 0.726. For the most effective diagnostic VAT ultrasound indices, the cut-off values in metabolic syndrome were (200 patients): 21.12 cm2 for the inferior part of perirenal fat (AUC = 0.983); and 47.00, 61.3 and 72.7 mm for the distance between the internal surface of the rectus abdominis muscle and the anterior wall of the aorta, the posterior wall of the aorta and the lumbar vertebra (AUC = 0.960, 0.966, 0.968, respectively). Ultrasound VAT measurements highly correlated with CT results. Cut-off VAT values, determined by ultrasound for the patients with metabolic syndrome, yielded good diagnostic operational characteristics.

Abstract
Obesity is associated with adverse metabolic diseases including cardiovascular disease (CVD) and chronic kidney disease (CKD). These obesity-related diseases are highly associated with excess fat accumulation in adipose tissue. However, emerging evidence indicates that visceral adiposity associates more with metabolic and cardiovascular risk factors. Perirenal adipose tissue, surrounding the kidney, is originally thought to provides only mechanical support for kidney. However, more studies demonstrated perirenal adipose tissue have a closer association with renal disease than other visceral fat deposits in obesity. Additionally, perirenal adipose tissue is also an independent risk factor for CKD and even associated more with CVD. Thus, perirenal adipose tissue may be a connection of CVD with CKD. Here, we will provide an overview of the perirenal adipose tissue, a neglected visceral adipose tissue, and the roles of perirenal adipose tissue linking with CVD and CKD and highlight the perirenal adipose tissue as a potential strategy for future therapeutics against obesity-related disease.

Abstract
Although visceral obesity is recognized as a risk factor for cardiovascular diseases (CVDs), the efficacy of omental fat removal in CVD treatment is still controversial. There is a need to identify other visceral fat depots for CVD management. This review aims to provide a summary on perirenal fat as an important risk factor for CVD. Studies on epidemiology, anatomy, and function of perirenal fat were reviewed. Observational studies in humans suggest that excessive perirenal fat increases the risk of hypertension and coronary heart disease. Anatomy studies prove that perirenal fat is unique compared to other connective tissues in that it is well vascularized, innervated, and drains into the lymphatic system. Other special morphological features include a complete fascia border, sympathetic-independent development of architecture, and proximity to the kidneys. Based on these anatomical features, perirenal fat regulates the cardiovascular system presumably via neural reflex, adipokine secretion, and fat-kidney interaction. These new insights suggest that perirenal fat may constitute a promising target for CVD management.

Abstract
The number of obese or overweight humans continues to increase worldwide. Hypertension is a serious disease that often develops in obesity, but it is not clear how obesity increases the risk of hypertension. However, both obesity and hypertension increase the risk of cardiovascular diseases (CVD). In this review, we examine how obesity may increase the risk of developing hypertension. Specifically, we discuss how the adipose-derived hormone leptin influences the sympathetic nervous system (SNS), through actions in the brain to elevate energy expenditure (EE) while also contributing to hypertension in obesity.

Abstract
Background Human immunodeficiency virus (HIV) infection and antiretroviral treatment are associated with metabolic and cardiovascular complications that potentially increase the risk of atherosclerosis and cardiovascular disease in this population. Measurement of arterial wall thickness has been used as a surrogate of extent, severity and progression of atherosclerosis. A cross-sectional cohort study was performed to compare the validity of two non-invasive arterial measures: carotid intima-media thickness (IMT), a parameter of atherosclerosis, and ophthalmic artery resistance index (OARI), an index of occlusive carotid artery disease. Methods A total of 95 patients receiving highly active antiretroviral therapy (HAART) for more than 12 months were consecutively enrolled. IMT and OARI were measured by 7.5 MHz linear probe. Results There was a significant linear increase in IMT and OARI values as the grade of cardiovascular risk (0.70 and 0.69 for very low risk, 0.86 and 0.72 for low risk and 0.98 and 0.74 for medium/high risk, p < 0.001). A IMT > 0.83 and an OARI > 0.72 were the most discriminatory values for predicting a cardiovascular risk ≥ 10% (sensibility 89.6% and 75.8%; sensitivity 70.5% and 68.4%; p < 0.001). Conclusions Our data indicate that OARI may have a potential as a new precocious marker of subclinical atherosclerosis in HIV-1-infected patients.
