By the end of 2019 emerged a cluster of pneumonia that was caused by a novel SARSCoV- 2 virus. The disease, subsequently named COVID-19, has a wide range of signs and symptoms, including fever, respiratory and gastrointestinal manifestations, and kidney disease that can evolve to a nutritional imbalance through direct and indirect mechanisms. Moreover, the prognosis of COVID-19 could worsen in high-risk populations like kidney disease patients, given their depressed immunity and impaired nutritional state. Therefore, previous reports suggest prioritizing a nutritional approach in these patients, adjusting for individual dietary needs. Thus, we aim to explore the current knowledge about the clinical and nutritional implications of patients with COVID-19 who develop acute or chronic kidney disease, highlighting proposed dietary recommendations in this group of patients.
