One-year weight management lowers lipopolysaccharide-binding protein and its implication in metainflammation and liver fibrosis

Studies showed that the endotoxemia-related biomarker, lipopolysaccharide-binding protein (LBP), is associated with obesity and fatty liver. The level of LBP is reduced after surgical weight loss. This study aimed to verify the change of serum LBP levels after one-year medical weight management in subjects with obesity. A total of 62 subjects with obesity, 39 subjects with overweight, and 21 subjects with normal body mass index were enrolled for a one-year weight management program. Basic information, body composition analysis, clinical data, serum LBP level, and abdominal ultrasonography findings were collected. At baseline, the serum LBP levels of the obese and overweight subjects were significantly higher than that of the normal group (30.9±7.4 and 29.6±6.3 versus 23.1±5.6 μg/mL, respectively, p
