This article presented a review of the literature on the features of nutritional support for oncohematological patients who have undergone allogeneic (alloHSCT)/autologous hematopoietic stem cell transplantation (autoHSCT). Bone marrow transplantation associated with a high risk of developing nutritional deficiencies. Nutritional support (NP) is indicated for patients undergoing alloHSCT and autoHSCT in order to reduce the incidence of infectious complications and reduce the risk of developing severe forms of acute and chronic GVHD. Currently, there are recommendations for conducting NP in alloHSCT, while there are no recommendations for patients with autoHSCT. An important task in planning NP is the calculation of the daily energy requirement. Bone marrow transplantation accompanied by a prolonged negative nitrogen balance. The protein requirement for alloHSCT is significantly higher than for patients with chemotherapy alone – 1.5–2 g/kg per day. An effective method of controlling the needs of hematological patients during the analysis of HSCT and alloHSCT is the calculation of the nitrogen balance and the daily protein norm. In this article was analyzed the role of macronutrients and immunonutrients in the recovery of patients during alloHSCT. It has been shown that low levels of vitamin D and vitamin A increase the risk of development and the severity of the transplant versus host reaction. The addition of omega-3 fatty acids helps maintain an optimal proportion of calorie intake from lipids, as well as maintain the necessary level of triglycerides in the blood. The article presents data on reducing the risk of developing acute GVHD with systemic addition of omega-3 fatty acids. For a final assessment of the effect of the neutropenic diet on the development of infectious complications in oncohematological patients, randomized prospective multicenter studies with the development of a unified approach in choosing a diet for HSCT are needed.
