World Sickle Cell Awareness Day Highlights Critical Misconceptions

World Sickle Cell Awareness Day is observed annually on June 19, focusing attention on a genetic blood disorder impacting millions globally. On this occasion, Dr Nakul Pathak, a consultant in paediatrics and paediatric intensive care at Surya Mother & Child Super Speciality Hospital, outlined how the disorder affects individuals and dispelled five common myths.

Sickle cell disease affects haemoglobin, the protein in red blood cells responsible for oxygen transport. Healthy red blood cells are soft and flexible, easily navigating narrow blood vessels. Conversely, in sickle cell disease, some cells adopt a stiff, sticky, crescent shape. As a result, these cells can break down prematurely, leading to chronic anaemia, or block small vessels, restricting blood and oxygen supply to tissues.

In children, initial symptoms of sickle cell may be episodic. A child with the condition may appear healthy between episodes, making it difficult to gauge the ongoing changes within their blood.

Dr Pathak addressed five prevalent myths about sickle cell disease:

1. Sickle cell disease is an inherited genetic condition and does not transmit through casual contact, food, or coughing. A child inherits the disease when both parents pass on the genes for abnormal haemoglobin.

2. A person with the sickle cell trait has inherited one sickle cell gene and one normal gene. Most carriers experience no symptoms of the disease, though there may be rare instances of complications. If both parents are carriers, each pregnancy has a 25% chance of resulting in a child with sickle cell disease.

3. While pain is the most recognised symptom, damage extends beyond pain crises. Blocked blood circulation can impact vital organs, including the lungs, brain, spleen, kidneys, and eyes. Children may suffer from persistent anaemia, fatigue, delayed growth, and heightened risk of severe infections. Complications such as acute chest syndrome and stroke are serious and require prompt medical attention.

4. Pain crises can manifest suddenly and may be severely debilitating. "Research indicates that individuals with sickle cell disease are sometimes mistakenly labelled ‘drug-seeking’, which can delay proper pain relief," Dr Pathak remarked. Symptoms necessitate careful evaluation and timely medical management.

5. Although the prescription medication hydroxyurea can alleviate pain crises and acute chest syndrome, preventive measures can be implemented in early childhood. Vaccination, administering penicillin to eligible young children, and transcranial Doppler screening can help prevent infections and detect stroke risks. In select cases, stem-cell transplantation may cure patients, and new gene therapies are emerging as treatment options for those aged 12 and older.

Dr Pathak highlighted the importance of World Sickle Cell Day to confront misconceptions that affect understanding and treatment of the disease. "Pain crises must be taken seriously, sickle cell trait should not be confused with the disease, and families need accurate information regarding inheritance, warning signs, and available treatments," he stated. This day serves as a reminder for enhanced public awareness and education on sickle cell disorder, fostering better support and treatment for affected individuals.
