condition characterized by an increase in the production of red blood cells, or erythrocytes, in the blood. Primary polycythemia, also called erythremia, or polycythemia vera, is a chronic, progressive disease, most common in middle-aged men. It is characterized by overgrowth of the bone marrow, abnormally increased red blood cell production, and an enlarged spleen. Symptoms, include headache, inability to concentrate, and pain in the fingers and toes. There is a danger of blood clotting or hemorrhage (see thrombosis). Primary polycythemia is treated by radiation, periodic removal of some blood (phlebotomy), or chemotherapy with antimetabolite drugs, e.g., Cytoxan. In secondary polycythemia, or erythrocytosis, the proliferation of red blood cells results from the body's attempt to compensate for other conditions, such as prolonged lack of oxygen at high altitudes or chronic lung or heart insufficiency. Certain tumors are also associated with increased red blood cell production. In secondary polycythemia the treatment is directed toward the underlying cause.
分析性小结：红细胞增多症分为原发性和继发性。原发性红细胞增多症（真性红细胞增多症)是一种原因不明的慢性骨髓增殖性疾病,其特点是血红蛋白浓度和红细胞数大量增多. 继发性红细胞增多症是由于其他疾病或医学相关的状态导致的，也就是说，如果导致“红细胞增多”的那个疾病或医学相关的状态消除了，“红细胞增多症”也就随之消除。导致继发性红细胞增多症的原因很多，问题中提到的“High-oxygen-affinity hemoglobin高氧亲和力血红蛋白病”的其中之一。因此，“高氧亲和力血红蛋白性红细胞增多症”这句话，所表示的意思，由于高氧亲和力血红蛋白病导致的红细胞增多，前半部分，是一个病的名字(高氧亲和力血红蛋白病)，后半部分，是这个病导致出现的一个现象(红细胞增多症). 用英文来表达，是“（Secondary ）polycythemia caused by high-oxygen-affinity hemoglobin”
