Peroral Supplemental Nutrition in End-stage Renal Disease With and Without HIV Comorbidity

MRT-based Pilot Study to Evaluate Peroral Supplemental Nutrition for Prevention of Cachexia in End-stage Renal Disease With and Without HIV Comorbidity

End-stage renal disease is often accompanied by malnutrition due to less appetite, metabolic changes or both. Human immunodeficiency virus-infection may exacerbate the state of malnutrition. In a pilot study, we recruit both HIV invected and non-infected patients on hemodialysis. Non-HIV patients will be randomized to peroral supplemental nutrition or no peroral supplemental nutrition. All HIV patients will receive peroral supplemental nutrition. The nutritional state will be determined in magnet resonance tomography at the start and at the end of the study (muscle diameter of triceps m.) and with laboratory parameters (plasma albumin and others). The hypothesis is that supplemental peroral nutrition (a total 250 kcal per day) will stop loss of muscle mass in end-stage renal disease patients (compared to their counterparts without supplemental peroral nutrition) as well as in the high risk group of HIV patients. This pilot study may lead to larger randomized clinical trials and, may affect dietary recommendations.

In end-stage renal disease (ESRD), cachexia is a common finding. Metabolic changes, malnutrition, or both appear to be the underlying problems. In fact, lean body mass per body weight better predicts prognosis than creatinin based models (NDT, 2004.19:1182). In addition, comorbidity such as HIV infection may exacerbate cachexia found in ESRD. Whether or not daily supplemental, high-caloric nutrition in ESRD corrects a catabolic state in ESRD is unclear. Hypothesis to be tested: Daily supplemental high-caloric nutrition beneficially affects cytokine stimulation (TNF alpha, IL 1beta, IL 6, CrP) and nutritional state (cross sectional area of triceps m. in mid-humerus position (MRT), plasma albumin) in in HIV-positive hemodialysis patients and in chronic hemodialysis patients compared to chronic hemodialysis patients without supplemental nutrition.

HIV-positive hemodialysis patients (as a high risk group for cachexia) will be given daily drinks of Renilon 7.5 (125 ml, 2 kcal/ml) as peroral supplemental nutrition on top to their recommended high-protein, high-caloric diet.

HIV-positive hemodialysis patients will be given daily supplemental nutrition (125 ml, 2 kcal/ml) on top of recommended high-protein, high-caloric regular diet

Chronic hemodialysis patients will be given daily peroral supplemental nutrition (125 ml/d, 2 kcal/ml) on top of their recommended high-protein, high caloric diet
