From the Guidelines
The management of sickle cell disease requires a comprehensive approach including preventive care, pain management, and disease-modifying therapies to reduce morbidity, mortality, and improve quality of life. Hydroxyurea is the cornerstone medication, typically started at 15-20 mg/kg/day and titrated based on response, with a goal of increasing fetal hemoglobin production to reduce sickling episodes 1. Other disease-modifying therapies include L-glutamine (10-30 g daily), crizanlizumab (5 mg/kg IV monthly), and voxelotor (1500 mg daily) 1.
Key Components of Sickle Cell Disease Management
- Preventive care: penicillin prophylaxis (125 mg twice daily for children under 3,250 mg twice daily for older children) recommended until age 5, and vaccinations against encapsulated organisms 1
- Pain management: prompt analgesia with NSAIDs and opioids, along with hydration for acute pain crises
- Disease-modifying therapies: hydroxyurea, L-glutamine, crizanlizumab, and voxelotor to reduce sickling events and prevent complications
- Regular transfusions: may be needed for stroke prevention in high-risk patients, guided by transcranial Doppler screening 1
- Comprehensive care: regular screenings for complications like retinopathy, nephropathy, and pulmonary hypertension 1
Importance of Transfusion Support
Transfusion support remains a key intervention in the management of patients with sickle cell disease, with specific indications, mode of red cell administration, and transfusion-related complications posing significant challenges for patients and providers 1.
Bone Marrow Transplantation
Bone marrow transplantation offers the only potential cure for sickle cell disease but carries significant risks and requires careful patient selection 1.
Pulmonary Hypertension Management
For patients with sickle cell disease who have an increased risk for mortality, hydroxyurea is recommended, and for those who are not responsive to or not candidates for hydroxyurea, chronic transfusion therapy may be suggested 1.
In summary, a comprehensive approach to managing sickle cell disease, including preventive care, pain management, disease-modifying therapies, and regular transfusions, is crucial to reducing morbidity, mortality, and improving quality of life.

From the Research
Causes of Sickle Cell Disease Symptoms
- Sickle cell disease is an inherited disorder characterized by hemoglobin S polymerization leading to vaso-occlusion and hemolytic anemia, resulting in a variety of pathological events, causing both acute and chronic complications 2.
- The production of abnormal hemoglobin molecules, specifically hemoglobin S, causes red blood cells to take on a crescent or sickle shape, leading to various health complications 3.
- Increased blood viscosity, caused by the presence of RBCs with abnormal deformability and aggregation, may increase vascular resistance and increase the risk of acute and chronic vascular complications 4.
- Chronic hemolysis results in decreased nitric oxide (NO) bioavailability, which may compromise vasodilation and participate in the development of chronic vasculopathy 4.
Management of Sickle Cell Disease
- Hydroxyurea is a medication that increases the production of fetal hemoglobin and is commonly used to reduce the frequency and severity of pain crises 2, 3, 5.
- Pain management with analgesics, hydration, and blood transfusions to improve oxygen delivery are also treatment options for SCD 3.
- Bone marrow or stem cell transplants can cure select individuals with severe SCD 3.
- Adding hydroxyurea to chronic transfusion therapy for patients with SCA reduces transfusion burden and is a feasible treatment option 5.
- Folic acid supplements are commonly given to SCD patients, but more research is needed to determine their potential benefits in the management of SCD 6.
