The Wild, Uncharted Territory of the Morbidly Obese, critically ill, Renal Failure Patient

Does anybody know of any good articles about dosing protein for very obese patients with renal failure? It appears to be a very unknown area. It is confusing because if they are obese we dose them really high with protein here (like 1.7-2!) but then if they are undialyzed with CRF their creatinines (like say, 22.6!!!) and BUNs (250!!) are crazy high. But then their albumin is low! AH! So any knowledge ya'll have would be much appreciated....
