Use of a renal-specific oral supplement by haemodialysis patients with low protein intake does not increase the need for phosphate binders and may prevent a decline in nutritional status and quality of life

Background. Protein-energy wasting is a frequent and debilitating condition in maintenance dialysis. We randomly tested if an energy-dense, phosphate-restricted, renal-specific oral supplement could maintain adequate nutritional intake and prevent malnutrition in maintenance haemodialysis patients with insufficient intake. Methods. Eighty-six patients were assigned to a standard care (CTRL) group or were prescribed two 125-ml packs of Renilon 7.5® daily for 3 months (SUPP). Dietary intake, serum (S) albumin, prealbumin, protein nitrogen appearance (nPNA), C-reactive protein, subjective global assessment (SGA) and quality of life (QOL) were recorded at baseline and after 3 months. Results. While intention to treat analysis (ITT) did not reveal strong statistically significant changes in dietary intake between groups, per protocol (PP) analysis showed that the SUPP group increased protein (P < 0.01) and energy (P < 0.01) intakes. In contrast, protein and energy intakes further deteriorated in the CTRL group (PP). Although there was no difference in serum albumin and prealbumin changes between groups, in the total population serum albumin and prealbumin changes were positively associated with the increment in protein intake (r = 0.29, P = 0.01 and r = 0.27, P = 0.02, respectively). The SUPP group did not increase phosphate intake, phosphataemia remained unaffected, and the use of phosphate binders remained stable or decreased. The SUPP group exhibited improved SGA and QOL (P < 0.05). Conclusion. This study shows that providing maintenance haemodialysis patients with insufficient intake with a renal-specific oral supplement may prevent deterioration in nutritional indices and QOL without increasing the need for phosphate binder

Bioelectrical impedance analysis in clinical practice: implications for hepatitis C therapy BIA and hepatitis C

<p>Abstract</p> <p>Background</p> <p>Body composition analysis using phase angle (PA), determined by bioelectrical impedance analysis (BIA), reflects tissue electrical properties and has prognostic value in liver cirrhosis. Objective of this prospective study was to investigate clinical use and prognostic value of BIA-derived phase angle and alterations in body composition for hepatitis C infection (HCV) following antiviral therapy.</p> <p>Methods</p> <p>37 consecutive patients with HCV infection were enrolled, BIA was performed, and PA was calculated from each pair of measurements. 22 HCV genotype 3 patients treated for 24 weeks and 15 genotype 1 patients treated for 48 weeks, were examined before and after antiviral treatment and compared to 10 untreated HCV patients at 0, 24, and 48 weeks. Basic laboratory data were correlated to body composition alterations.</p> <p>Results</p> <p>Significant reduction in body fat (BF: 24.2 ± 6.7 kg vs. 19.9 ± 6.6 kg, genotype1; 15.4 ± 10.9 kg vs. 13.2 ± 12.1 kg, genotype 3) and body cell mass (BCM: 27.3 ± 6.8 kg vs. 24.3 ± 7.2 kg, genotype1; 27.7 ± 8.8 kg vs. 24.6 ± 7.6 kg, genotype 3) was found following treatment. PA in genotype 3 patients was significantly lowered after antiviral treatment compared to initial measurements (5.9 ± 0.7° vs. 5.4 ± 0.8°). Total body water (TBW) was significantly decreased in treated patients with genotype 1 (41.4 ± 7.9 l vs. 40.8 ± 9.5 l). PA reduction was accompanied by flu-like syndromes, whereas TBW decline was more frequently associated with fatigue and cephalgia.</p> <p>Discussion</p> <p>BIA offers a sophisticated analysis of body composition including BF, BCM, and TBW for HCV patients following antiviral regimens. PA reduction was associated with increased adverse effects of the antiviral therapy allowing a more dynamic therapy application.</p

Nutritional Intervention in Chronic Liver Failure

Patients suffering from chronic liver failure (CLF) frequently are malnourished and do not achieve an adequate intake of nutrients, in particular protein. Low protein intake and loss of muscle mass and function, termed sarcopenia, are indicators of a poor outcome. CLF patients, therefore, should be screened for risk of malnutrition using a validated tool, and if positive, full assessment of nutritional status is mandatory including search for sarcopenia. The main goal of nutritional intervention is to provide enough protein (1.2–1.5 g × kg&lt;sup&gt;–1&lt;/sup&gt; × day&lt;sup&gt;–1&lt;/sup&gt;) and to ensure adequate energy intake (total energy 30 kcal × kg&lt;sup&gt;–1&lt;/sup&gt; × day&lt;sup&gt;–1&lt;/sup&gt;; 1.3 × resting energy expenditure). Livers of CLF patients are deplete in glycogen and, therefore, prolonged periods of fasting (&amp;#x3e;12 h) must be avoided in order to prevent further breakdown of muscle protein for gluconeogenesis. Therefore, late evening snacks or even nocturnal oral nutritional supplements improve total body ­protein status and thus, are recommended. Nutrition intervention should be stepped up from nutrition counselling to oral nutritional supplements, to enteral tube feeding, or to parenteral nutrition as appropriate. As in other malnourished patients, the prevention of refeeding syndrome or vitamin/trace element deficiency should be taken care of.</jats:p

Ernährung bei Leberzirrhose: wichtige Tipps für Klinik und Praxis

AbstractLiver disease and nutritional status affect each other mutually. Hepatic function is impaired by malnutrition and can be improved by nutrition therapy. Liver cirrhosis leads to prognostically relevant malnutrition in a stage dependent manner. Protein depletion and sarcopenia are its key features. Patients with liver cirrhosis should undergo systematic screening for risk of malnutrition and if positive sarcopenia should be assessed and a nutrition plan devised. In cirrhotic patients, spontaneous food intake frequently does not meet requirements and prolonged (&gt; 12 h) periods of fasting must be avoided. In a stepwise fashion nutritional counseling, oral nutritional supplements, enteral tube feeding and parenteral nutrition as third-line-therapy should be used. In cirrhotic patients, nutrition therapy can improve morbidity and mortality by ensuring the adequate provision of energy, protein and micronutrients.</jats:p

Ernährung bei multimorbiden Patienten – Daten oder Meinungen?

AbstractPolymorbidity and old age are rather the rule than the exception in hospitalised patients. Malnutrition is common in such patients and should be identified by appropriate screening and assessment measures in order to devise a nutrition plan and act accordingly. Unlike in the UK or The Netherlands, malnutrition screening and nutrition teams are not mandatory for German hospitals. Malnutrition and, in particular, sarcopenia are indicators of a nutrition associated risk or increased morbidity and mortality. Malnutrition can affect patients of any medical discipline and, therefore, is managed most efficiently by the interdisciplinary and multiprofessional nutrition team. By this approach goal directed nutrition therapy can improve morbidity and mortality of hospitalised patients.</jats:p
