Multidisciplinary nutritional consensus on assessment and nutritional dietary treatment in patients with chronic kidney disease and SARS-CoV-2 infection.

The presence of malnutrition in patients with chronic kidney disease (CKD) is high, it can be made worse by SARS-CoV-2 infection. The nutritional assessment should be adapted to minimize the infection, recommending monitoring: weight loss percentage, body mass index (BMI), loss of appetite, analytical parameters and functional capacity using the dynamometer. As well as the sarcopenia assessment using the SCARF scale, and the possibility of using the GLIM criteria in those patients who have been tested positive by MUST. It is important to adapt the nutritional recommendations in the caloric and protein intake, to the CKD stage and to the SARS-CoV-2 infection stage. In patients with hypercatabolism, to prioritize preserving the nutritional status (35kcal/kg weight/day, proteins up to 1.5g/kg/day). The rest of the nutrients will be adapted to CKD stage and the analytical values. In the post-infection stage, a complete nutritional assessment is recommended, including sarcopenia. The energy and protein requirements in this phase will be adapted to the nutritional status, with special attention to the loss of muscle mass. Dietary recommendations need to be tailored to side effects of SARS-CoV-2 infection: anorexia, dysphagia, dysgeusia, and diarrhea. Anorexia and hypercatabolism makes it difficult to meet the requirements through diet, therefore the use of oral nutritional supplements is recommended as well as the enteral or parenteral nutrition in severe phases.
