Sickle Cell Disease: Causes, Symptoms, Types, Treatment and Cost in India

Sickle cell disease (SCD) is a group of inherited red blood cell disorders. It is one of the most common genetic diseases in the world and is particularly widespread in sub-Saharan Africa, where countries such as Nigeria, the Democratic Republic of Congo, Tanzania, Uganda and Ghana carry a very large share of the global burden. It is also common in parts of the Middle East, including Saudi Arabia, Oman, Bahrain and Yemen, and among tribal communities in central and western India. For families, SCD can mean repeated pain crises, hospital admissions, missed school and serious complications such as stroke. However, with early diagnosis, preventive care and medicines such as hydroxyurea, most people with SCD can live much longer and healthier lives, and a bone marrow transplant can offer a permanent cure for suitable patients. India has become a trusted destination for sickle cell transplants for patients from Africa and the Gulf.

What is Sickle Cell Disease?

Red blood cells contain haemoglobin, the protein that carries oxygen. Normal red cells are soft and round, allowing them to pass easily through small blood vessels. People with SCD produce an abnormal haemoglobin called haemoglobin S (HbS). When oxygen levels fall, HbS forms stiff strands that bend red cells into a crescent or sickle shape. These sickle cells are rigid and sticky, block small blood vessels and break down early, after about 10 to 20 days instead of the normal 120 days. This causes pain, anaemia and damage to organs throughout the body.

Types of Sickle Cell Disease

• HbSS (sickle cell anaemia): two sickle genes; usually the most severe form.
• HbSC disease: one sickle gene and one haemoglobin C gene, common in West Africa; usually milder but with eye and bone complications.
• HbS beta-thalassaemia: one sickle gene and one beta-thalassaemia gene; severity varies.
• Other forms such as HbSD and HbSE.

People with one sickle gene and one normal gene have sickle cell trait (HbAS). They are generally healthy and do not have the disease, but they can pass the gene to their children.

Causes and Risk Factors

SCD is caused by a change (mutation) in the beta-globin gene. It is inherited in an autosomal recessive pattern, which means a child must inherit a sickle gene from each parent to have the disease. When both parents have sickle cell trait, each pregnancy has a 1 in 4 chance of a child with SCD, a 1 in 2 chance of a child with the trait and a 1 in 4 chance of a child with neither.

The sickle gene became common in regions where malaria was widespread, because sickle cell trait offers some protection against severe malaria. This explains its high frequency in Africa, the Arabian Peninsula and parts of India. Marriages between close relatives, common in some communities in the Middle East and South Asia, increase the chance that both parents carry the gene.

Symptoms of Sickle Cell Disease

Symptoms usually begin after about 5 to 6 months of age, when foetal haemoglobin naturally falls. They vary greatly between individuals:

• Pain crises (vaso-occlusive crises): sudden episodes of severe pain in the bones, chest, back, arms, legs or abdomen, lasting hours to days. They can be triggered by cold, dehydration, infection, stress or high altitude.
• Anaemia: tiredness, pale skin and breathlessness
• Jaundice: yellowing of the eyes
• Hand-foot syndrome (dactylitis): painful swelling of the hands and feet in babies and young children
• Frequent infections: the spleen is damaged early in life, increasing the risk of serious bacterial infections
• Delayed growth and puberty
• Vision problems due to damage to the retina

Complications

• Stroke, including silent strokes affecting learning, especially in children
• Acute chest syndrome, a lung complication similar to pneumonia
• Splenic sequestration, where blood pools suddenly in the spleen
• Avascular necrosis of the hip or shoulder
• Gallstones, leg ulcers and priapism (painful prolonged erection)
• Kidney damage, pulmonary hypertension and heart problems

Warning Signs That Need Urgent Care

• Fever of 38.5 degrees C (101 degrees F) or higher, especially in children
• Chest pain, cough or difficulty breathing
• Sudden weakness, numbness, difficulty speaking, facial droop or severe headache
• Sudden swelling of the abdomen with paleness and weakness
• Severe pain not relieved by usual medicines
• Erection lasting more than 2 to 4 hours

How is Sickle Cell Disease Diagnosed?

• Newborn screening using a heel-prick blood test, practised in many countries and expanding in Africa and India
• Haemoglobin electrophoresis or HPLC: identifies the types of haemoglobin present
• Complete blood count and peripheral smear showing anaemia and sickle cells
• Solubility (sickling) test: a quick screening test, but it cannot distinguish disease from trait
• DNA testing for confirmation and prenatal diagnosis
• Transcranial Doppler (TCD) ultrasound: recommended for children from age 2 to 16 to detect high stroke risk
• HLA typing of the patient and siblings when a bone marrow transplant is being considered

Treatment Options for Sickle Cell Disease

Preventive Care

• Penicillin prophylaxis from early childhood until at least age 5
• Vaccinations against pneumococcus, meningococcus, Haemophilus influenzae and others
• Folic acid supplements
• Malaria prevention for those living in or travelling to malaria regions
• Good hydration and avoiding extreme cold

Hydroxyurea (Hydroxycarbamide)

Hydroxyurea is a daily oral medicine that increases foetal haemoglobin, which prevents sickling. It reduces pain crises, acute chest syndrome, transfusion needs and hospital stays, and is now recommended for most children and adults with HbSS. It is inexpensive and widely available in India.

Blood Transfusion

Transfusions are used for severe anaemia, acute chest syndrome and stroke, and regular transfusion programmes prevent stroke in high-risk children. Long-term transfusion leads to iron build-up, which is treated with iron chelation medicines such as deferasirox.

Pain Management

Crises are treated with fluids, oxygen if needed, and appropriate pain relief, from paracetamol to stronger opioid medicines in hospital.

Bone Marrow (Stem Cell) Transplant: The Curative Option

A bone marrow transplant replaces the patient's bone marrow with healthy marrow from a donor. It is currently the established cure for SCD. Results are best in children and young people who have a fully matched brother or sister, but Indian centres also perform haploidentical (half-matched) transplants using a parent or sibling, which greatly increases access for families without a full match. A donor with sickle cell trait can usually donate. Transplant is usually considered for patients with severe disease, such as stroke, recurrent acute chest syndrome or frequent crises.

Newer Treatments

Gene therapies approved in some Western countries in recent years can also cure SCD, but they are extremely expensive and not yet widely accessible. Research, including programmes in India, aims to make such therapies more affordable in the future.

Cost of Sickle Cell Disease Treatment in India

Indicative starting prices at JCI/NABH-accredited hospitals in Delhi/NCR are:

The final cost depends on the patient's age and condition, the type of donor, complications during transplant and the length of stay. Contact Satyug Healthcare at +91-8860606766 / +91-9910655125 (WhatsApp) for a free medical opinion and cost estimate.

Living with Sickle Cell Disease

• Drink plenty of water every day, especially in hot climates.
• Avoid extremes of temperature, very strenuous exercise and high altitude.
• Treat fever immediately and seek medical care.
• Take hydroxyurea, folic acid and penicillin as prescribed.
• Attend regular check-ups, including eye, kidney and heart screening, and yearly TCD in children.
• Psychological support helps patients and families cope with chronic illness.

For a bone marrow transplant, the patient and donor generally stay in India for about 3 to 4 months, as the patient is monitored closely for infections and graft-versus-host disease after the transplant.

Prevention

SCD can be prevented by knowing your carrier status. Premarital and pre-pregnancy screening, as practised in Saudi Arabia, Bahrain and other countries, helps couples make informed decisions. Couples who are both carriers can choose prenatal diagnosis or IVF with preimplantation genetic testing (PGT) to have a child free of SCD.

Frequently Asked Questions

Can sickle cell disease be cured?

Yes. A bone marrow transplant can cure SCD, with the best results in children with a matched sibling donor. Gene therapy is another emerging cure but is very costly and not widely available.

What is the right age for a sickle cell bone marrow transplant?

Results are best when the transplant is done in childhood, ideally before serious organ damage occurs. Adults can also be transplanted after careful assessment.

Can a brother or sister with sickle cell trait be a donor?

Yes. A matched sibling with sickle cell trait can usually donate safely, and the patient will then have trait-like blood without disease symptoms.

Is hydroxyurea safe for children?

Yes. Hydroxyurea has been used for decades and is recommended for children from as early as 9 months of age with HbSS. Blood counts are monitored regularly.

How long is the stay in India for a transplant?

Typically about 3 to 4 months, including pre-transplant tests, the transplant itself and close follow-up until blood counts and immunity recover.

Does a person with sickle cell trait need treatment?

No. Sickle cell trait is not a disease. People with trait should stay hydrated during extreme exercise and should know their status before planning a family.

What triggers a sickle cell crisis?

Common triggers include dehydration, cold weather, infections, fever, stress, high altitude and very strenuous exercise.

What reports should I send for an opinion?

Please share the haemoglobin electrophoresis or HPLC report, recent blood counts, a summary of crises and complications, transfusion history and any HLA typing results for the patient and siblings.
