Abstract

Myelodysplastic syndrome (MDS) is a group of heterogeneous diseases derived from hematopoietic stem cells characterized by hemolytic anemia and high risk of conversion to acute leukemia. MDS is an age-related disease in which approximately 80% of patients are over 60years of age, male and female. Anemia is the most common clinical condition, and many patients are also associated with infection and bleeding. When the amount of α globin synthesis is insufficient, the remaining β chain forms tetramer β4, i.e. HbH. The latter forms a precipitate in red blood cells, leading to hemolytic anemia, called HbH disease, the majority of which is congenital, a small number of patients with myelodysplastic syndrome and acute myeloid leukemia may appear HbH (called acquired HbH disease). We reported a 71years old male patient diagnosed as myelodysplastic syndromes (MDS) in our hospital. The patient has a negative α-thalassemia gene test. The H band is detected by hemoglobin electrophoresis. This article analyzed and discussed this case with MDS, as well reviewed MDS.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.
