From the Guidelines
Management strategies for common blood disorders prioritize addressing the underlying cause while managing symptoms, with a focus on minimizing morbidity, mortality, and improving quality of life. For patients with myeloproliferative neoplasms, such as essential thrombocythaemia or polycythaemia vera, continuing current cytoreductive treatment with hydroxycarbamide, anagrelide, interferon alfa, or ruxolitinib is recommended 1. Additionally, ensuring a 3-month supply of these agents and avoiding the cessation of ruxolitinib, especially during the COVID-19 pandemic, is crucial to prevent immune cytokine release syndrome.
Key considerations in managing blood disorders include:
- For anemia, treatment depends on the type, with iron deficiency anemia requiring iron supplementation, vitamin B12 deficiency needing B12 injections or oral supplements, and folate deficiency requiring folic acid 1.
- Hemolytic anemias may require corticosteroids, immunosuppressants, or splenectomy in severe cases.
- Bleeding disorders like hemophilia necessitate factor replacement therapy, while von Willebrand disease often responds to desmopressin (DDAVP).
- Thrombotic disorders, such as deep vein thrombosis, are managed with anticoagulants, including heparin for acute treatment, followed by warfarin or direct oral anticoagulants (DOACs) like apixaban or rivaroxaban for 3-6 months or longer.
- Polycythemia vera requires phlebotomy to maintain hematocrit below 45% and low-dose aspirin, while essential thrombocythemia is treated with hydroxyurea to reduce platelet counts.
- Leukemias necessitate specialized approaches, including chemotherapy, targeted therapy, immunotherapy, or stem cell transplantation.
Supportive care is crucial across all blood disorders and may include:
- Blood transfusions
- Growth factors like erythropoietin or G-CSF
- Pain management
- Prevention of complications Regular monitoring of blood counts and organ function helps guide treatment adjustments and assess response to therapy 1.

From the Research
General Management Strategies for Common Blood Disorders
The management of common blood disorders, such as iron deficiency anemia, involves a comprehensive understanding of the underlying causes and the use of various treatment options.
- Diagnosis and treatment of iron deficiency anemia (IDA) depend on the age and gender of the patient, as well as the presence of any underlying conditions 3, 4.
- Iron supplementation is a key component of IDA management, with oral iron therapy being the first line of treatment in most cases 5.
- Intravenous iron supplementation may be used in patients who are intolerant or unresponsive to oral iron, or in cases where rapid correction of the iron deficit is required 6.
Iron Deficiency and Anemia
Iron deficiency is a leading contributor to the global burden of disease, particularly affecting children, premenopausal women, and people in low-income and middle-income countries 5.
- The diagnosis of iron deficiency anemia involves the measurement of hemoglobin and hematocrit levels, as well as the assessment of iron stores using serum ferritin and transferrin saturation 3, 4.
- Treatment of iron deficiency anemia aims to improve quality of life, with hemoglobin being a surrogate marker for treatment response 6.
Role of Iron in Hematopoiesis
Iron plays a crucial role in hematopoiesis, including the formation and functioning of erythrocytes, white blood cells, and platelets 7.
- Iron levels direct the lineage commitment of megakaryocytic/erythroid progenitors toward either megakaryocyte or erythroid progenitors, and contribute to cellular machinery, especially energy production in platelet mitochondria 7.
- Abnormally low total body iron stores can lead to thrombocytosis, while severe iron deficiency anemia can cause thrombocytopenia 7.
