摘要
The coronavirus disease 2019(COVID-19)is caused by the newly discovered SARS-CoV-2.Hematopoietic stem cell transplantation(HSCT)is a high-risk procedure.The novelty of COVID-19 has created more uncertainty during all phases of HSCT.It is thought that HSCT patients taking immunosuppressive agents are more likely to contract COVID-19 than healthy individuals are.Appropriate care precautions should be taken with patients undergoing HSCT to minimize the risk of COVID-19,and appropriate treatment methods must be followed in patients infected with COVID-19.Malnutrition has become a significant problem in HSCT patients during the COVID-19 pandemic.The causes of malnutrition in HSCT patients are multifactorial.However,the most important reason is the decrease in energy and nutrient intake.The HSCT procedure can lead to many complications such as dysgeusia,mucositis,diarrhea,constipation,xerostomia and vomiting/nausea.Improving the nutritional status of HSCT patients by managing each of these special complications with an appropriate nutritional approach is essential for successful engraftment.This review aims to provide a comprehensive overview of the specific complications affecting the nutritional status of HSCT patients and their nutritional approach during the challenging COVID-19 pandemic.
