Quick Answer
What families need to know about thalassaemia, sickle cell disease and genetic counselling.
Medically reviewed by Dr. Sachita Baniya • NMC 20158 • Kathmandu Neurology Clinic & Cognitive Center
Thalassaemia and sickle cell disease are inherited haemoglobin disorders. They affect red blood cells and can cause anaemia, pain, organ damage and serious complications. With good care, many people live full lives.
Thalassaemia
Thalassaemia is caused by reduced or absent globin chain production. Thalassaemia major requires regular transfusion to maintain haemoglobin, along with iron chelation to prevent organ damage. Thalassaemia trait is usually mild and does not require treatment.
Sickle cell disease
Sickle cell disease causes red cells to become rigid and sickle-shaped. This leads to vaso-occlusion, pain crises, haemolysis and organ complications. Care includes hydration, pain management, vaccination, penicillin prophylaxis in children and hydroxyurea in selected patients.
Preventing crises
- Stay well hydrated
- Avoid extreme cold and dehydration
- Treat infections promptly
- Keep vaccinations up to date
- Follow the individual care plan
When to seek urgent care
Seek emergency care for severe pain not controlled at home, fever, chest pain, breathlessness, sudden weakness, confusion or severe headache. Acute chest syndrome, stroke and sepsis are emergencies.
Family screening and genetic counselling
Both conditions are inherited. Carrier testing and genetic counselling help families understand the risk to children and make informed decisions. Prenatal diagnosis is available in specialised centres.
Treatment advances
Hydroxyurea, improved transfusion and chelation have changed outcomes. Allogeneic transplant can cure selected patients, and gene therapy is emerging. These options require specialist assessment.
The bottom line
Inherited haemoglobin disorders need lifelong, proactive care. Regular follow-up, vaccination, family screening and prompt treatment of complications make a real difference.
Frequently asked questions
Answers reviewed by Dr. Jitendra Prasad Yadav • MBBS, MD (Internal Medicine), FICN (Neurology), FCNV, FIHM • NMC 8029
Trait carriers usually have mild or no anaemia. Disease occurs when both genes are affected and can require lifelong transfusion.
Repeated transfusions cause iron overload, which can damage the heart, liver and endocrine organs. Chelation removes excess iron.
Allogeneic transplant can cure selected patients. Gene therapy is emerging. Most care focuses on preventing and treating complications.
Dehydration, infection, cold, stress, hypoxia and menstruation can trigger crises. Avoiding triggers helps, but crises can still occur.
