Objective: This study was designed to evaluate the relationship among circulating adiponectin (ADPN), left ventricular mass (LVM) and cardio-metabolic comorbidities in subjects at higher global cardiovascular risk (score of"Cuore Project").
Methods: 115 consecutive subjects were grouped according to normal or low ADPN levels. Left ventricular internal diameter (LVID/h), total LV mass (LVM), LVM index (LVMI), relative wall thickness (RWT), LV ejection fraction by echocardiography and diastolic parameters, by pulsed-wave Doppler were calculated.
Results: Low-ADPN subjects were characterized by a significantly higher prevalence of some cardiometabolic comorbidities (obesity, visceral obesity, diabetes and insulin resistance, LVH, metabolic syndrome (MetS), coronary artery syndrome (CAD). BMI (P < 0.0001), WHR (P < 0.03), trigly cerides (P < 0.001), HOMA-IR (P < 0.001), LVM, LVMI, IVST and RWT (P < 0.0001) were significantly higher and HDL-C (P < 0.001) and LVEF were significantly lower in low-ADPN than in normal-ADPN subjects. LVMI correlated directly with BMI (P < 0.001), WHR (P < 0.001) MBP (P < 0.001), MetS (P < 0.001) and inversely with ADPN (P < 0.0001). Multiple regres- sion analysis indicated that ADPN was independently associated with LVMI.
Conclusions: ADPN might be considered a key component mediating the cross-talk between adipose tissue, cardiac cells and the vasculature. Accordingly, its routine measurement might become a new target in the management of global CV risk.

Objective: The role of adiponectin (APN) in regulating inflammation is well recognized in metabolic disease, but the dysregulation of APN in lower respiratory tract infection (LRTI) remains controversial. We aimed to measure APN and its signaling receptors, adiponectin receptor (AdipoR), in peripheral blood mononuclear cells (PBMCs) from LRTI patients to explore their potential roles in the LRTI process.
Methods: A total of 99 LRTI patients from the Second Xiangya Hospital of Central South University were categorized into acute (n=35) and non-acute (n=64), and non-severe (n=62) and severe (n=37) groups.

Background And Aims: The adipocyte-derived adiponectin (APN) has potent insulin-sensitizing and anti-inflammatory properties. The adipose tissue is known to be the main source for APN in the circulation, but sites and mechanisms which remove APN from blood are still unknown in humans.
Methods And Results: We reviewed APN data obtained in previous studies in which the inter-organ exchange of amino acids and cytokines was measured in our laboratory.

Hepatic stellate cells (HSCs) are key drivers of local fibrosis. Adiponectin, conventionally thought of as an adipokine, is also expressed in quiescent HSCs. However, the impact of its local expression on the progression of liver fibrosis remains unclear.

: The prevalence of metabolic syndrome in children has been increasing, raising concerns about early detection and clinical management. Adipokines, which are secreted by adipose tissue, play a critical role in metabolic regulation and inflammation, while gamma-glutamyl transferase (GGT), as a liver enzyme, is linked to oxidative stress and metabolic disorders. The objective was to examine the association of circulating adipokines and GGT with metabolic syndrome risk in school-aged children from Northeast Mexico.
