Aside from the beneficial effects of metabolic surgery on cardiometabolic system, its impact on inflammation still worth examining. Thus, this study aims to investigate the effect of CRP on adipose and vascular cells, and their responses to metabolic surgery in obese diabetic patients.Patients and Methods: The expression of CRP and RAS- and ERK-related factors in the adipocytes and VSMCs were measured. Obese patients with type 2 diabetes who underwent metabolic surgery were followed up for 2 years thereafter. Laboratory tests, which included serum hs-CRP levels and visceral fat thickness (VFT), were obtained before and after surgery.Results: CRP administration significantly and dose-dependently increased the intracellular-free calcium concentration ([Ca2+]i) in cultured adipocytes and in the VSMCs. CRP administration significantly increased ACE, Ang II, AT1R and p-ERK expressions, but reduced ACE2 expression in both the adipocytes and VSMCs. Clinical study showed that VFT was closely associated with serum hs-CRP. Furthermore, VFT and serum hs-CRP were found to be highly associated with blood pressure. Finally, metabolic surgery remarkably decreased blood pressure, visceral fat and serum hs-CRP levels.Conclusion: CRP has a detrimental effect on cardiometabolic cells, aside from functioning merely as a biomarker. Serum hs-CRP levels are highly associated with hypertension and visceral obesity, which can be antagonized by metabolic surgery in obese diabetic patients.Keywords: CRP, metabolic surgery, type 2 diabetes |
