CONTEXT:
Betatrophin is produced primarily by liver and adipose tissue, and has been recently reported as a novel hormone promoting β cell proliferation and β cell mass and improving glucose tolerance.
OBJECTIVE:
Since it is markedly regulated by nutritional status, we hypothesized that circulating betatrophin levels might be affected by pathophysiological conditions altering body weight.
SETTING AND PATIENTS:
We analyzed circulating betatrophin levels in 149 female patients, including 99 with extremeBMI(30 anorexia nervosa,24obese,45morbidobeseand50healthy eating/weight controls).
OUTCOME:
Measurements. Serum betatrophin levels and its correlations with different anthropometric and biochemical parameters.
RESULTS:
Plasma betatrophin levels were significantly elevated in anorexic patients, whereas its levels were reduced in morbid obese women when compared to normal weight women. Plasma betatrophin correlated negatively with weight, BMI, fat percentage, glucose, insulin, HOMA and positively correlated with HDL.
CONCLUSIONS:
These results suggest that metabolic status is an important regulator of circulating betatrophin levels.
