What is a Sickle Cell Disease (SCD)?
Sickle cell disease (SCD) is a group of inherited blood disorders caused by abnormal haemoglobin, most commonly haemoglobin S. This abnormal haemoglobin can make red blood cells rigid and sickle-shaped, making them more likely to break down early and block small blood vessels. This can lead to anaemia, painful vaso-occlusive crises, and progressive damage to organs such as the lungs, kidneys, brain, bones, and spleen. SCD is inherited when a child receives disease-causing haemoglobin variants from their parents.
What is the Importance of Timely Treatment?
Timely diagnosis and comprehensive treatment can help reduce painful crises, prevent complications and protect organ function. Regular monitoring allows doctors to identify anaemia, infection, stroke risk, kidney problems, eye complications and other effects of SCD at an earlier stage. Disease-modifying medicines, transfusion programmes, vaccination and preventive care can reduce complications, while selected patients with severe disease may be evaluated for hematopoietic stem-cell transplantation or gene therapy.
What are the Common Symptoms of Sickle Cell Disease (SCD)?
- Episodes of severe pain, known as vaso-occlusive crises
- Chronic or recurrent anaemia
- Fatigue and weakness
- Shortness of breath
- Pale skin or yellowing of the eyes
- Swelling of the hands and feet, particularly in young children
- Frequent infections
- Delayed growth or puberty in some children
- Bone and joint pain
- Abdominal pain
- Vision problems
- Symptoms related to stroke or neurological complications
- Priapism in some males
- Chronic organ-related complications in severe disease
Causes and Risk Factors of Sickle Cell Disease (SCD)
Causes
- Sickle cell disease results from inherited changes in the HBB gene, which provides instructions for producing beta-globin, a component of haemoglobin.
- Different combinations of abnormal haemoglobin genes can produce different forms of SCD.
- The most severe and common form, HbSS, generally occurs when a child inherits a sickle haemoglobin gene from both parents.
Risk Factors
- Having parents who carry sickle haemoglobin or another disease-causing haemoglobin variant
- Family history of sickle cell disease
- Inheriting two disease-causing haemoglobin variants
- Genetic ancestry associated with a higher prevalence of sickle haemoglobin, including parts of Africa, the Middle East, the Mediterranean, South Asia and other regions
- Lack of access to early screening and comprehensive SCD care, which can increase the risk of preventable complications
Latest Research and Technologies in the Treatment of Sickle Cell Disease (SCD) in Malaysia
- Advances in sickle cell disease care include disease-modifying treatment, improved transfusion strategies and potentially curative approaches such as haematopoietic stem-cell transplantation and gene therapy for selected patients. Gene-based therapies involve collecting a patient's own blood-forming stem cells, modifying them in a specialised laboratory and returning them after intensive conditioning treatment. They require specialised facilities, careful patient selection and long-term follow-up. In Malaysia, confirm the availability of specific gene therapies and advanced cellular treatments directly with the treating centre, as regulatory approval and clinical access may vary.
Treatment options for Sickle Cell Disease (SCD)
Blood Transfusion Therapy: Red blood-cell transfusions may treat severe anaemia or prevent or manage selected complications,s such as stroke. Long-term transfusion programmes require monitoring for iron overload and other transfusion-related complications.
Stem-Cell Transplantation : Allogeneic hematopoietic stem-cell transplantation can potentially cure SCD in selected patients. Suitability depends on factors such as disease severity, organ health, age, donor availability and the risks associated with transplantation.

Gene Therapy: Selected patients with severe SCD may be evaluated for autologous gene-based therapies. These approaches involve collecting the patient's own blood-forming stem cells, modifying them in a specialised laboratory and returning them after conditioning treatment.
- Clinical assessment:
- Medical and Haematological Evaluation: A detailed history is taken to assess pain crises, fatigue, anaemia, infections, transfusion history, jaundice, breathing problems, neurological symptoms, vision changes, bone complications and other SCD-related symptoms.
- Complete Blood Count and Peripheral Blood Assessment: A complete blood count evaluates haemoglobin, red blood cells, white blood cells and platelets. A peripheral blood smear can show red-cell morphology and other blood abnormalities associated with SCD.
- Haemoglobin Analysis: Haemoglobin electrophoresis, high-performance liquid chromatography, or other specialised tests can identify abnormal haemoglobin types and help determine the specific SCD genotype or haemoglobinopathy.
- Assessment of Organ Complications: Depending on age and symptoms, evaluation may include kidney function and urine testing, liver assessment, pulmonary evaluation, eye examination, and neurological assessment.
- Genetic and Family Assessment: Genetic counselling and testing may help clarify the inherited haemoglobin pattern and provide information about reproductive risks and family screening.
- Imaging Tests:
- Transcranial Doppler Ultrasound: Used particularly in children with SCD to assess cerebral blood-flow velocities and help identify increased stroke risk.
- Brain MRI and MRA: May be recommended when neurological symptoms, a previous stroke, or a silent cerebral injury is suspected.
- Chest X-ray: May be used when acute chest syndrome, pneumonia, or another chest complication is suspected.
- Echocardiography: May be used to evaluate cardiac structure and function when clinically indicated.
- Ultrasound or MRI: May help evaluate abdominal, bone, or other organ complications depending on symptoms.
- Retinal Imaging: Ophthalmologic imaging can detect sickle-cell-related retinal changes.
MediRehab (a chain of Rehab centres, part of MediGence) provides comprehensive tele-rehabilitation services designed to support Sickle Cell Disease (SCD) patients in Malaysia. These services include:
- Physical Activity and Exercise: Gentle, individualised activity may help maintain strength and fitness. Adjust exercise intensity to the patient's symptoms and clinical advice, with attention to hydration and avoiding excessive exertion.
- Pain and Mobility Rehabilitation: Physiotherapy may help patients manage chronic musculoskeletal pain, maintain joint mobility, and improve functional movement while avoiding symptom-worsening activities.
- Fatigue and Energy Management: Structured activity planning, appropriate rest, sleep support and treatment of underlying anaemia can help patients manage chronic fatigue and maintain daily activities.
- Psychological and Self-Management Support: Counselling, patient education and chronic-pain support can help patients cope with recurrent crises, treatment demands, school or work limitations and the emotional effects of living with a chronic blood disorder.
- Medicines for SCD aim to reduce sickling, prevent complications, and manage acute symptoms. Hydroxyurea is an established disease-modifying medicine that can increase fetal haemoglobin and reduce the frequency of pain crises in appropriate patients. Other medicines may manage pain and selected disease-related complications. Pain-relief medicines are used during crises, while patients receiving repeated transfusions may need monitoring and treatment for iron overload. Regular follow-up helps assess treatment response and identify adverse effects.
