In September 2020, hemophagocytic lymphohistiocytosis was diagnosed. Ukrainian doctors couldn't help Ulyana with the treatment of such a complex disease. In Israel, the Ichilov Medical Center accepted Ulyana for treatment with a subsequent bone marrow transplant from a donor.

The parents turned to the "Keren or for Child" charity fund for help in fundraising for a bone marrow transplant. To our greatest regret, Ulyana couldn't stand it. It's impossible to find such words of support to ease your pain even a little. Please accept our deepest condolences for the loss of your daughter. We share your grief and support you. Blessed memory to you, Ulyana...
