Introduction:
Adropin and irisin are known as peptide hormones that regulate food intake and energy expenditure.
Aim:
Our study aimed to investigate the association between adropin and irisin levels with obesity and metabolic
indicators of obese patients in China.
Methodology & Theoretical Orientation:
70 overweight and obesity patients who were regularly followed up in
the multidisciplinary clinic for obesity and 28 healthy individuals who visited physical examination center of Peking
University First Hospital were enrolled in our study. Demographic data and obesity related metabolic indicators
were collected during the first visit. Serum adropin and irisin levels were evaluated using EIA kit and ELISA kit,
respectively. Statistical analysis was performed using SPSS 21.0.
Findings:
Serumadropin levels reduced significantly in overweight/obesity group comparingwith healthy individuals
(6.92±2.43 vs. 7.97±1.84, p=0.043), while irisin levels showed no difference between the two groups. Adropin level
was negatively associated with UA level in whole study individuals (r=-0.223, p=0.030) and positively associated
with HDL-c level (r=0.214, p=0.043). In overweight/obesity subjects, adropin level was positively associated with
proportion of daily protein intake (r=-0.278, p=0.029). Adropin levels decreased significantly in patients with
metabolic syndrome (6.68±2.44 vs. 7.67±2.13, p=0.036), hyperuricemia (6.52±2.42 vs. 7.52±2.10, p=0.036), low-
HDL (6.49±2.57 vs. 7.57±2.08, p=0.036) and NAFLD (6.73±2.36 vs. 7.68±2.10, p=0.039), comparing with those
without the disease. Irisin levels reduced significantly in patients with NAFLD (11.43 vs. 13.18, p=0.043), comparing
with those without NAFLD.
Conclusion & Significance:
Adropin might play a beneficial role in obesity, lipid and uric acid metabolism, and the
level decreased in obese, hyperuricemia, low-HDL or NAFLD patients. Irisin levels reduced in NAFLD patients.

Biography
Difei Lu has her expertise in evaluation and passion in improving the health and wellbeing of patients with diabetes or obesity in China. Graduated as MD in
Peking University Health Science Center, she works as a Specialist in Endocrinology Department at Peking University First Hospital. After the multidisciplinary
team for obesity of Peking University First Hospital was launched since 2016, she participated in the clinical practice and collected data. Since then, nearly one
thousand obesity patients were regularly followed up in the MDT for obesity. This approach provided a real world-based data for weight control efficacy of MDT
for obesity in China.
