Melatonin Plus Aminoacids for Sarcopenic Elderly

Not Applicable
Completed
Conditions
Sarcopenia
Interventions
Dietary Supplement: Essential Aminoacids (eAA)
Combination Product: Essential Aminoacids + melatonin
Other: Placebo
Registration Number
NCT03784495
Lead Sponsor
Azienda di Servizi alla Persona di Pavia
Brief Summary

To evaluate the effectiveness of melatonin and essential aminoacid supplementation on body composition, protein metabolism, strength and inflammation. The investigators performed a Randomized controlled parallel groups preliminary trial in 159 elderly sarcopenic people (42/117 men/women) assigned to 4 groups: isocaloric placebo (P, n=44), melatonin (M, 1 mg/daily, n=42,), essential aminoacids (eAA 4 g/daily, n=40) or eAA plus melatonin (eAAM, 4 g eAA and 1 mg melatonin/daily, n= 30). The period of intervention was 4 weeks. Data from body composition (DXA), strength (handgrip test) and biochemical parameters for the assessment of protein metabolism (albumin) and inflammation (PRC) were collected at baseline and after the 4-week intervention

Primary Outcome Measures
NameTimeMethod
Change in Handgrip Strenght0, 30 days

Handgrip strength assessed using a Jamar dynamometer adhering to the standardized protocol recommended by the American Society of Hand Therapists. A weak handgrip was defined as \<30 kg for men and \<20 kg for women, based on the average value of the two handgrip measurements of the dominant hand

Change in Total Fat Mass and Total Free Fat Mass (DXA)0, 30 days

Body composition by dual-energy X-ray absorptiometry (DXA). Body composition was measured by DXA, using a Lunar Prodigy DXA (GE Medical Systems, Waukesha, WI). Free Fat mass and Fat mass of specific body regions were measured in kilograms.

Secondary Outcome Measures
NameTimeMethod
HeightAt baseline (0)

Height measured in meters

Change in erythrocyte sedimentation rate (ESR)0, 30 days

Erythrocyte sedimentation rate (ESR) was expressed in mm/hr.

Change in dietary intakeMeasures taken at day 1,2,3 and at day 28,29,30

A trained dietitian used a calibrated dietetic spring scale to weigh all foods served and returned for 3 consecutive days at the beginning and end of the study

Change in Body Weight0, 30 days

Body Weight measured in kilograms

Change in blood lipids (total cholesterol and triglycerides)0, 30 days

Blood lipids (total cholesterol and triglycerides)were measured by automatic biochemical analyzer. They were reported as mg/dl

Change in High-sensitivity C-reactive protein (CRP)0, 30 days

High-sensitivity C-reactive protein (CRP) was expressed in mg/dl.

Change in glycaemia0, 30 days

glycemia was expressed in mg/dl

Change in serum proteins0, 30 days

Serum proteins and albumin were measured by automatic biochemical analyzer. They were reported as g/dl

Change in Mini Nutritional Assessment (MNA)0, 30 days

A mini nutritional assessment (MNA) was performed for all participants. The MNA uses 18 questions regarding simple measurements and a brief questionnaire involving an anthropometric assessment (weight, height and weight loss), a general assessment (lifestyle, medication and mobility), and a dietary assessment (number of meals, food and fluid intake, self-assessment of eating autonomy and self-perception of health and nutrition). Every answer give up to a maximum of 3 points. The sum of all points gives the total MNA. A maximum of 30 points can be achieved. A score of ≥ 24 points describes a well-nourished status. A score of 17 to 23.5 points indicates a risk of malnutrition, while less than 17 points indicates malnutrition.
