Maintaining Immune and Mitochondrial Functions in Old Adults With SAfe Nutrition.
Sponsor: Patrizia D'Amelio
Summary
Aging is associated with an increased inflammation named "inflammageing" and with an altered immune response. Different mechanisms have been proposed to explain the phenomenon of inflammageing and increased oxidative stress: deficiencies in essential amino acids, and some micronutrients have an important impact and may induce immune cell dysregulation. Mitochondrial dysfunction may explain the complex relationship between malnutrition sarcopenia, immune dysfunction and aging. Therefore, a personalized nutritional strategy aiming to improve mitochondrial function, decrease oxidative stress, down-regulate inflammation and restore immunity appears to be a logical approach in order to treat malnutrition and its biological and clinical consequences. MIMOSA will investigate the role of nutritional supplements in rescuing altered mitochondrial function and redox state imbalance.

Interventions
BCAA
daily administration of oral nutritional supplements (ONS) 1) providing whole proteins together with dietary advice according with the ESPEN nutrition guidelines. All the patients will receive the standard commercially available product used at CHUV (Resource protein ®, nestle) and nutritional counselling (SC) and 4 gram per day of BCAAs mixture. Ratio between the BCAAs will be Leucine/Isoleucine/Valine=2:1:1
Micronutriments
daily administration of oral nutritional supplements (ONS) 1) providing whole proteins together with dietary advice according with the ESPEN nutrition guidelines. All the patients will receive the standard commercially available product used at CHUV (Resource protein ®, nestle ) and nutritional counselling (SC) and Vitamin A 1200 mg RE, Vitamin D3 2000 IU, Thiamine B1 100 mg, Cobalamin B12 10 mcg, Ascorbic acid C 200 mg, Iron 30 mg, Selenium 100 mcg, Zinc 20 mg, Omega-3 PUFA 1 g
standard treatment + placebo
daily administration of oral nutritional supplements (ONS) 1) providing whole proteins together with dietary advice according with the ESPEN nutrition guidelines. All the patients will receive the standard commercially available product used at CHUV (Resource protein ®, nestle ) and nutritional counselling (SC) and maltodextrin 4 g as placebo
