[Place of biomarkers in the renutrition of patients with serious Covid-19 infection: discussion around a clinical case]. / Place des biomarqueurs dans la renutrition des patients ayant une infection grave à Covid-19 : discussion autour d'un cas clinique.

ABSTRACT

Covid-19 infection is a potentially serious disease. Overweight, obesity, and diabetes are comorbidities frequently found in the severe form of the disease. Appropriate nutritional management of the patient is an integral part of care. We will discuss the renutrition of a 76-year-old, obese (BMI = 35kg/m2), malnourished patient, according to the 2021 Haute Autorité de santé criteria, with Covid-19 infection, admitted to the intensive care unit at the Bordeaux University Hospital for an acute respiratory distress syndrome. Adaptation of nutritional intakes was achieved by clinical and biological monitoring. A refeeding syndrome was treated on the first day of hospitalization in the intensive care unit. After thiamine supplementation and when kalemia and phosphatemia have been normalized, renutrition was started. Parenteral nutrition as a complement to oral nutrition was used. Parenteral nutrition was well tolerated; recommended caloric and protein intakes were achieved by the fourth day of hospitalization. The clinical evolution was favorable. In conclusion, patients with Covid-19 infection should be considered malnourished when admitted to the intensive care unit. Macro and micronutrient intakes adapted to metabolically stressed patients are essential. Biological monitoring including monitoring of ionogram, phosphate, uremia, creatinine, liver function tests and blood glucose is essential in the nutritional management of patients with serious Covid-19 infection.
