Background: Rheumatoid arthritis (RA) is a chronic inflammatory disease associated with cardiovascular disease (CVD) development. Galectin-3 (Gal-3) is a potential biomarker for RA, and it has been found to be related to the activity, severity, chronicity of RA, and predictive of cardiovascular comorbidity.
Background Rheumatoid arthritis (RA) is a chronic inflammatory disease resulting in disability as well as joint damage. Early diagnosis and treatment are crucial for improving outcomes. RA patients have a twofold elevated risk of cardiovascular disease (CVD) development compared to the general population. Carotid ultrasound is a noninvasive imaging modality that can detect early signs of atherosclerosis and plaque buildup in the carotid arteries, which are strongly associated with CVD risk. Galectin-3 (Gal-3), a protein involved in inflammation and fibrosis, is suggested as one of the potential RA markers. Despite the growing interest in galectin-3 as a biomarker for CVD, few studies have investigated its role in RA patients. To our knowledge, only two studies have examined the correlation between galectin-3 and CVD in RA patients, and they have yielded conflicting results. This study aimed to determine the serum level of Gal-3 as well as its correlation with carotid ultrasound assessment for cardiovascular involvement in RA patients.Results RA cases demonstrated substantially elevated Gal-3 levels than controls (P < 0.001), and a 3.38 pg/mL cut-off value was proven to be an excellent predictor of RA diagnosis (AUC, 0.98). Gal-3 levels were proven to be positively associated with DAS-28, Larsen score, and carotid intima-media thickness (CIMT) (P-value 0.006, 0.026, < 0.001, respectively). A positive association was also detected between right (RT) and left (LT) CIMT and disease duration (P-values of 0.040 and 0.042, respectively).Conclusions Gal-3 is a biomarker for RA that is not only associated with activity and severity of the disease but it is also related to the chronicity of the disease and is a predictor of cardiovascular comorbidity.
