  • Beschreibung: <jats:title>Abstract</jats:title><jats:sec><jats:title>Background:</jats:title><jats:p>Renal function could be evaluated with different equations such as Cockcroft–Gault formula (C‐G), Mayo Clinic Quadratic (MAYO) and four MDRD variables. Clinical application of different formulae in conditions with severe energy restriction or in obese subjects is still a matter of investigation.</jats:p></jats:sec><jats:sec><jats:title>Method:</jats:title><jats:p>Renal function of 55 anorexia nervosa (AN) and 44 bulimia nervosa (BN) patients was evaluated with C‐G formula for creatinine clearance calculation, and glomerular filtration rate (GFR) was estimated with MAYO and MDRD equations.</jats:p></jats:sec><jats:sec><jats:title>Results:</jats:title><jats:p>BN group was older and had higher weight, body mass index (BMI), body surface area than AN subjects; however, their mean BMI was in the normal range. AN group had better renal function than BN one when it was evaluated with MAYO and MDRD; on the contrary, it was worse when it was calculated with C‐G. The results obtained from the three formulae were poorly correlated and Bland–Altman analysis confirmed that the results of the three formulae were not in agreement.</jats:p></jats:sec><jats:sec><jats:title>Discussion:</jats:title><jats:p>C‐G is inaccurate when it is applied to obese or cachectic subjects. MDRD underestimates renal function in normal‐high GFR. MAYO seems to be a good alternative to the other equations leading to correct classification of patients; therefore, it should be used to diagnose eating disorder subjects as renal insufficient. © 2010 by Wiley Periodicals, Inc.
