Hepatokine and Proinflammatory Cytokine Profile in Patients with Carotid Atherosclerosis and Metabolic...

Background and Aims: Hepatokines have a regulatory function in adipose tissue inflammation, metabolic dysfunction-associated steatotic liver disease (MASLD), cardiovascular diseases, and atherosclerosis. Our aim was to evaluate the profile of proinflammatory cytokines and hepatokines in patients with MASLD and carotid atherosclerosis (CA). Methods: A prospective and basic research study was conducted on patients with MASLD. Clinical data were collected from a detailed medical history. Liver stiffness was measured using transient elastography, and carotid Doppler ultrasound was performed. Levels of basic biochemical parameters, systemic inflammation markers (TNF-α, IL-6, IL-10, IL-18), and hepatokines (FGF21, ANGPTL4, fetuin-A) were determined. The results were analyzed with SPSS v22.0 software. Results: Sixty-seven patients with MASLD were included, 72.1% were women, and the mean patient age was 53.9 + 11.3 years. Atherosclerosis was found in 11 patients (16.2%), and carotid intima-media thickness (CIMT) was altered in the right carotid of 13 patients (19.1%), in the left carotid of 19 (27.9%), and bilaterally in 7 (10.3%). Greater age (p = 0.001) and high blood pressure (p = 0.028) were correlated with atherosclerosis. There were no differences in systemic inflammation markers, and the hepatokines FGF21 and fetuin-A tended to increase in the presence of CIMT and CA alterations, regardless of fibrosis. Conclusions: In our population, patients with MASLD had a 16.6% prevalence of CA, and the risk increased with age and a history of high blood pressure. FGF21 tended to increase in patients with MASLD + atherosclerosis, and fetuin-A was correlated with CIMT alterations, suggesting that the combination of these markers could guide us to suspect early endothelial alterations in patients with MASLD.
