The aim of this study was to evaluate the role of the adrenoreceptor beta 3 (ARβ3) in the cardiovascular function on Metabolic Syndrome (MS) induced by fructose overload. Male mice after weaning (8-10g) were divided into 4 groups (n=7/group): FVB Control (C) and ARβ3 Knockout Control (Kβ3C), with free access to food and water for 8 weeks; FVB fructose (F) and ARβ3 Knockout fructose (Kβ3F), with free access to food and fructose added to the drinking water (10%) for 8 weeks. At the end of the protocol, intraperitoneal glucose tolerance test was performed. Triglycerides and HDL fractions were evaluated by colorimetric methods. The animals were submitted to catheterization of carotid artery. This catheter was connected to a transducer and continuous signals of blood pressure (BP) was recorded. The variability of the resultant signal was evaluated in frequency domain. Visceral fat deposits were collected, weighted and normalized as fat (mg)/body weight (g). Results: fructose increased the fasting glycemia in the knockout group (Kβ3C=93±3 vs. Kβ3F=122±7 mg/dL) and decreased the glucose tolerance in both fructose groups. Fructose increased the triglycerides and decreased HDL cholesterol. The uric acid increased in the knockout animals. There was an increase on visceral fat deposits only in FVB animals (C=10±2 vs. F=16±1 mg/g), as well as on blood pressure (C=123±4 vs. 136±2 mmHg) There was an increase on blood pressure variability for all experimental groups compared to Control (C=10.7±1 vs. F=36±11; Kβ3C=50±7; Kβ3F=24±4 mmHg 2 ) as well as on peripheral sympathetic modulation (C=3.3±0.4 vs. F=8.1±0.1; Kβ3C=22.9±3; Kβ3F=9.2±2 mmHg 2 ). Furthermore, Kβ3F showed a decrease on blood pressure variability and peripheral sympathetic modulation. Our data suggest that the hypertension induced by fructose is related with adiposity. Moreover, the blood pressure variability and its sympathetic modulation are dependent of the ARB3. The association between fructose and ARβ3 knockout leads to the loss of the sympathetic modulation.

Background: Blood pressure variability (BPV) is a potential prognostic predictor for all-cause mortality. Objectives: We conducted a retrospective cohort study to compare the prognostic value of long-term BPV with intra-dialytic BPV in hemodialysis (HD) patients. Materials and Methods: We included 611 HD patients and collected their baseline blood pressure (BP) measurements for 1 year and monitored them for 40 months. Long-term BPV was assessed by pre-dialysis BP SD and pre-dialysis absolute BP residual metric. Intra-dialytic BPV was assessed by intra-dialytic BP average real variability and intra-dialytic absolute BP residual. Results: Long-term systolic BPV showed a weak correlation with mean BP, but a stronger correlation with intra-dialytic BPV. High long-term systolic blood pressure (SBP) SD and long-term SBP residual metrics were associated with high all-cause mortality (p = 0.0084 and 0.0056, respectively), while no such association was found for intra-dialytic BPV or diastolic BPV. According to receiver operating characteristic curve with mortality as dependent variable, long-term SBP residual metric showed the strongest prognostic ability (area under curve [AUC] 0.679, p = 0.0006), which was even stronger in patients with BP ≥140/90 mm Hg (AUC 0.713, p = 0.0004). After completely adjusting for confounders, long-term SBP residual metric remained significantly associated with all-cause mortality (hazard ratio 1.628 per quartile; 95% CI 1.086–2.441). Conclusions: Our results suggest long-term SBP residual metric to be a better predictor of all-cause mortality in HD patients, which could be used as an additional target for BP management.
