Abstract
There is growing evidence linking growth differentiation factor 15 (GDF15) to both metabolic dysfunction-associated steatotic liver disease (MASLD) and cardiovascular (CV) risk. Nevertheless, the potential relationship between circulating levels of GDF15 and key features of MASLD being predisposed to atherosclerotic CV disease is not fully unveiled. The aim of this study was to deepen into the role of circulating GDF15 levels on metabolic-associated liver injury and atherosclerotic CV disease. We determined the serum GDF15 levels in 156 participants of a metabolic patient-based cohort, and cross-sectionally explored its associations with liver injury and an advanced atherosclerotic lipoprotein profile assessed by nuclear magnetic resonance (1H-NMR). Additionally, we prospectively evaluated the association between GDF15 levels at baseline and incident atherosclerotic CV disease after a 10-year follow-up. GDF15 was related to liver injury and inflammatory hallmarks, and it increased the likelihood for liver steatosis independently of confounding factors. Likewise, GDF15 was positively associated with an atherogenic profile, particularly with the number of very-low-density lipoproteins (VLDL) particles and its cholesterol and triglyceride content, and with an indicator of subclinical atherosclerosis (i.e., carotid intima–media thickness (cIMT)). The baseline serum GDF15 levels were higher in the patients with atherosclerotic CV disease (10.6%) after a 10-year follow-up than in the individuals without CV disease. Altogether, this study provides new insights into the role of GDF15 in both MASLD and CV disease.
