Protein Supplementation In Dialysis Patients

3. december 2017 opdateret af: Tilakavati Karupaiah, National University of Malaysia

Exploring The Therapeutic Benefits Of Oral Protein Supplementation In Malnourished Dialysis Patients

The dialysis population has a strikingly high incidence of mortality. The life expectancy of chronic dialysis patients is 20 years less than that of the general population. Approximately 50% of individuals with end stage renal disease (ESRD) die from a cardiovascular (CV) cause with mortality being 15 to 30 times higher than the age-adjusted CV mortality in the general population. There is also a steady increase of patients with diabetes and the older age groups coming into dialysis. The treatment of patients with ESRD aims at prolonging life, achieving good nutritional status and promoting the best possible functioning and quality of life (QOL). Several factors that are beyond adequacy of dialysis predict high mortality in ESRD patients. Associated co-morbidities and malnutrition factors are independently associated and the combined presence of both malnutrition and co-morbidities manifest the worst survival.Therefore this study investigates the efficacy of protein supplementation in improving health status and quality of life among peritoneal dialysis (PD) patients. This research will also generate basic data about significant health markers critical to the health status of PD patients.

Detaljeret beskrivelse

This study is a randomised, open labeled controlled trial where a total of 74 PD patients (37 supplemented; 37 control) were recruited from government and private settings. Subjects were randomised to either the intervention or control group. The intervention group received hydrolysed whey protein supplement and diet counselling for 6 months while the control group received only diet counselling for 6 months.

Patients who consented were first subjected to a screening for identification of eligible subjects. The screening involved basic anthropometry measures (height, weight, BMI), routine biochemistry result obtained from medical record, assessment of nutritional status and dietary evaluation. About 4ml of pre-dialysis blood was also collected by respective nurses for additional laboratory parameters (hsCRP).

During the 6 months of treatment period, patients in both control and intervention groups were assessed at baseline and end of the study (at 6 months) for anthropometry assessment, laboratory results, medical condition, hospitalisations, nutritional status, dietary intake and compliance towards supplementation (intervention group only).

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Ceprolac
Received supplementation which added 27.6g protein and 114kcal to daily nutritional intake as well as standard diet counselling for 6 months
Kosttilskud: Ceprolac
The supplement was packed into two ~15g sachets in powder form of a 90-94% whey protein isolate and hydrolysed whey. The protein powder was dissolved in 75-100ml water at room temperature and was ingested post meal once daily.
Placebo komparator: Dietary counseling (DC)
Received standard diet counselling only for 6 months.
Andet: Dietary counseling (DC)
Received standard dietary counseling at baseline and month 6.
