The scientific term for erythropoietic syndrome is hemophagocytic syndrome. Symptoms mainly include fever, progressive pancytopenia, hepatosplenomegaly, hepatitis and coagulation dysfunction. 1. Most of the patients with hemophagocytic syndrome have fever, usually the body temperature is above 38.5 ℃, and the duration of fever is more than one week, and the cause of fever is mainly due to the increase of the index of inflammatory factors. 2. Activated macrophages destroy a large number of blood cells due to excessive inflammatory reaction, resulting in progressive reduction of whole blood cells. 3. A large number of blood cells are lysed and destroyed, causing lymphocytes to infiltrate tissues and organs, resulting in hepatosplenomegaly. 4. The enlarged liver and spleen further lead to the elevation of transaminases and bilirubin, and the production of a large number of inflammatory cytokines causing tissue damage, resulting in liver function damage and coagulation dysfunction. There may be other symptoms of Hemophagocytic Syndrome. If you suspect such a disease, it is recommended that you go to the hospital in time to make a diagnosis and receive standardized treatment with the help of your doctor.
