FUCHS-TARLOVSKY, Vanessa et al. Abnormalities in energy expenditure and respiratory parameters in patients with Prader Willy syndrome. Rev. chil. nutr. [online]. 2012, vol.39, n.4, pp.159-163. ISSN 0717-7518.

Introduction: Prader Willi Syndrome (PWS) is a complex genetic disorder with many manifestations relating to hypothalamic insufficiency. One such feature is obesity associated with an imbalance between caloric intake and expenditure due to hyperphagia and slow metabolic rate. Different procedures, as the use of appetite suppressants, surgical interventions and change in behavioral techniques have been used to try to limit food intake, but there is not convincing results about it. Aim: To compare the resting energy expenditure (REE) in PWS patients with obese patients without the syndrome matched by age and BMI (Body Mass Index). Subjects and methods: We conducted a comparative, observational and descriptive study in PWS and obese patients, matched for age, sex and BMI. RER was measured by indirect calorimerty and by anthropometry (BMI, skin-fold triceps and bíceps). A t-Student test for independent samples was used to demonstrate homogeneity between subjects and a series of ANCOVA analysis was performed on each of the parameters displayed by the indirect calorimetry. Results: Twenty mestizo-mexican patients, 10 with PWS and 10 with obesity were analyzed matched by age, BMI and gender. We found a statistically significant difference in the REE, the volume of oxygen (ml/min) and tidal volume (p <0.05). Conclusions: Prader Willy Syndrome per se produces changes in the REE in comparison with patients with only obesity.
