MON-605 Serum CD163, but Not Gal-3, Predicts Response to Liraglutide Therapy in Obese Patients

Liraglutide is a GLP-1 Receptor Agonist licensed to treat T2DM and obesity. Soluble CD163 (sCD163) is a marker of macrophage activation, the integral immunological component in inflammation associated with obesity. Gal-3 is a β-galactoside-binding lectin that has been implicated in the development of cardiovascular diseases and insulin resistance. Recent studies have suggested that Gal-3 is raised in obesity with levels correlating with markers of inflammation. In this study, we aim to elucidate if the levels of sCD163 and Gal-3 can be used to predict treatment outcomes of Liraglutide in obese patients. Thirty-four obese patients (58.8% female; 44.1% diabetic) were enrolled for 12-week Liraglutide therapy. Anthropometric parameters were assessed before and after. Serum levels for sCD163 and Gal-3 were measured using ELISA. Pre-treatment age (mean ± SD) was 52.41 ± 10.74y, BMI was 44.97±7.71 kg/m2, HbA1c was 47.18±15.96 mmol/mol, sCD163 was 284059.20 ± 71859.88 pg/ml and Gal-3 was 6584.83 ± 3477.59 pg/ml. Post-treatment, BMI reduced to 43.19±7.92 kg/m2 (p < 0.001), HbA1c to 43.59±16.00 mmol/mol (p
