Hematology specialist and anemia treatment: The role of a hematologist in managing anemia conditions
In the medical world, anemia is a common condition that affects the production of red blood cells, leading to a decrease in hemoglobin and oxygen transport in the body. Anemia has three stages, each with varying symptoms and treatment options.
In Stage 1, serum iron levels are normal, but iron stores are low. As the condition progresses to Stage 2, transferrin proteins and serum iron levels also decrease. In the final stage, hemoglobin levels drop, iron stores become depleted, and transferrin proteins and serum iron levels continue to decrease.
When the cause of anemia is not reversible, treatment will depend on individual factors. Hematologists, specialists who work in hospitals and outpatient clinics, play a crucial role in diagnosing and treating anemia. They use a variety of methods to diagnose anemia, including complete blood counts, blood smears, hematocrit, reticulocyte counts, bone marrow biopsies, viral panels, autoimmune markers, liver function tests, genetic testing, and imaging studies.
For aplastic anemia, a specific type of anemia, diagnosis involves demonstrating pancytopenia (reduction in red cells, white cells, and platelets) and confirming marrow failure via a bone marrow biopsy. Hematologists look for bone marrow hypocellularity and two or more cytopenias when diagnosing aplastic anemia. A bone marrow biopsy is essential for diagnosing aplastic anemia.
Treatment methods vary depending on anemia type and severity. For aplastic anemia, management includes immunosuppressive therapy and, importantly, allogeneic hematopoietic stem cell transplantation (HSCT) as a first-line therapy for severe cases. Other treatments may involve supportive care (transfusions), chemotherapy, radiotherapy, or targeted therapies in specific contexts.
In summary, hematologists diagnose anemia using blood tests such as a complete blood count (CBC), blood smear, hematocrit, and reticulocyte count to assess the quantity, shape, and maturity of red blood cells. For aplastic anemia, they also use bone marrow biopsies, viral panels, autoimmune markers, liver function tests, genetic testing, and imaging studies to exclude other causes and identify contributing factors.
Treatment for anemia, including aplastic anemia, may include stem cell transplantation and immunosuppressive therapy. It is essential to seek immediate medical advice if you or a loved one experiences sudden or serious symptoms of anemia, such as temporary losses of consciousness, shortness of breath, or low tolerance to exercise. If anemia is due to acute blood loss, the priority will be replenishing the blood supply through IV fluids.
If anemia occurs due to nutritional deficiency, a doctor may refer a person to a nutritionist for treatment involving replenishing nutrients through supplementation and dietary changes. Hematologists are also involved in diagnosing and treating conditions such as sickle cell disease and leukemia.
