title: Answers to all your questions about peritoneal urea clearance and nutrition in CAPD patients.
abstract: In summary, SA and a number of other indices related to nutritional status have been identified as being strongly predictive of outcome in CAPD patients. Evidence connecting these indices to KT/V urea, or even to protein intake, remains limited, however. Increased dialytic dose may well increase protein intake, but neither of these parameters have been shown prospectively to raise SA, total body nitrogen, or SGA status on a consistent basis. Studies addressing this issue, however, have been few and small, and more data are required. For now, we will likely continue to deal with malnutrition by attempting to raise small solute clearance and protein intake, but we should be aware that such measures will frequently be unsuccessful, and we must pay attention to other factors, particularly comorbidity. It is clear from this review that there are many unanswered questions relating to this topic and that, in particular, the effect of prospective increases in the dialytic dose needs to be further elucidated.
