ALTIS: Innovative Functional Food Based on Apulian Lens Culinaris for Contrasting Sarcopenia in Dialysis Patients
Study Details
Study Description
Brief Summary
The objective of the pilot study is to validate the clinical use of a dietary supplement for contrasting sarcopenia in dialysis patients.
The study aims at evaluating the effects of a nutritional supplement, consisting of flour from Lens culinaris of Altamura IGP, pea proteins and vitamins (A, B12, D, E) by achieving the following objectives:
-
Reduction of sarcopenia conditions, through improvement of nutritional and anthropometrical levels
-
Decrease of the serum levels of microbiota-derived uremic toxins
-
Reduction of intestinal permeability and inflammatory markers

|---|---|
| Experimental: Hemodialysis with sarcopenia 10 HD patients, affected by sarcopenia will a undergo 3-months supplementation with NATURLENS |
Dietary Supplement: NATURLENS
Oral administration of dietary supplement (26 g/day) to dissolve in 100 or 150 mL of water

| No Intervention: Controls 10 HD patients, affected by sarcopenia will be followed for 3 months without any supplementation |
Outcome Measures
Primary Outcome Measures
- Evaluation of muscle mass [3 months]
Change of muscle mass by bioelectrical impedance assessment (BIA)
Secondary Outcome Measures
- Change of sarcopenia conditions [3 months]
Change of sarcopenia assessed by the European Working Group on Sarcopenia in Older People (EWGSOP) guidelines through the SARC-F (Strength, Assistance with walking, Rise from a chair, Climb stairs and Falls) questionnaire. The SARC-F scale scores range from 0 to 10 (i.e. 0-2 points for each item; 0=best to 10=worst) and represents no sarcopenia (0-3) and sarcopenia (4-10).
- Change of Mini Nutritional Assessment (MNA) score [3 months]
Measurement of MNA questionnaire (12-14 points, normal nutritional status; 8-11 points, at risk of malnutrition; 0-7, malnourished)
- Change of anthropometric parameter [3 months]
Measurement of the arm circumference (cm)
- Change of body mass index (BMI) [3 months]
Measurement of BMI (kg/m^2)
- Change of gastrointestinal symptoms [3 months]
Change of gastrointestinal symptoms assessed by Gastrointestinal Symptom Rating Scale (GSRS) questionnaire (15 items scored 1-7 each, 1 representing the best and 7 the worse outcome for each item).
- Change of stool type [3 months]
Change of stool type evaluated by BRISTOL Stool Scale (range 1-7, lower and higher values representing worse outcome, middle values representing better outcome).
- Change of serum concentration of IS and pCS [3 months]
Change of free and total indoxyl sulfate (IS) and p-cresyl sulfate (pCS) serum concentrations (μg/mL) assessed by liquid chromatography/mass spectrometry
- Change of serum concentration of inflammatory markers [3 months]
Change of serum concentrations of interleukins: IL-6, TNF-α, IL-1, IL-8, IL-10 (pg/mL) evaluated by ELISA
- Change of blood glucose level [3 months]
Change of glycemia concentration (mg/dl)
- Change of insulin levels [3 months]
Change of insulin concentration (pmol/L)
- Change of endocrine parameters [3 months]
Change of C-peptide, growth hormone (GH), insulin-like growth factor 1 (IGF-1), testosterone concentration (ng/mL)
- Change of serum concentration of D-lactate [3 months]
Change of D-lactate serum concentration (uM)
Other Outcome Measures
- Gut microbiota [3 months]
Change of the relative abundance (%) of Operational Taxonomic Units (OTUs) of Firmicutes, Bacteroidetes,Proteobacteria, Verrucomicrobia, Actinobacteria, Synergistetes, Cyanobacteria, Euryarchaeota, Chloroflexi, Nitrospirae, Tenericutes, Fusobacteria, Thermotogae, Acidobacteria evaluated by fecal bacterial DNA genome sequencing.
