What is Sickle-cell disease Anaemia ?

Sickle-cell disease Anaemia, also known as Sickle cell disease, is a genetically inherited form of anaemia that is most frequent in people of African, Arabian, and Indian descent. It is a condition in which the body is unable to create enough red blood cells to deliver enough oxygen throughout the body. This can result in a stroke, acute chest syndrome, pulmonary hypertension, organ damage, blindness, gallstones, and other consequences. While there is no permanent cure for this disease, some treatment regimens can assist prevent any consequences that may occur as a result of it.

Causes of Sickle Cell Disease

A mutation in the gene that produces haemoglobin, the iron-rich substance found in red blood cells that gives blood its red colour, causes sickle cell disease.

The major type of haemoglobin in healthy people without sickle cell anaemia is HbA, which allows red blood cells to transport oxygen from the lungs to all regions of the body.

In persons with sickle cell anaemia, however, a distinct, mutant kind of haemoglobin, HbS, predominates. In de-oxygenated situations, this HbS impairs the circulation of oxygen throughout the body by causing red blood cells to take on a sticky, crescent-shaped or sickle-shaped shape. This exposes the red blood cells to destruction – haemolysis – and can also result in a blockage in blood arteries – occlusion – leading to progressively serious health issues as the condition progresses.

Symptoms

Sickle cell anaemia symptoms can vary from person to person and alter over time. The majority of the symptoms are caused by the haemolysis and occlusion that occurs along the course of the disease. Typical symptoms include:

Fatigue caused by anaemia: Normal red blood cells function for 120 days before being replaced. Sickle-shaped red blood cells, on the other hand, are readily destroyed within 10 to 20 days and so impair oxygen circulation in the body. This causes chronic weariness as well as other concerns such as shortness of breath, fainting spells, and so on.

Hand and foot inflammation: Painful swelling of the hands and feet is caused by sickle-shaped red blood cells that tend to obstruct blood flow to the extremities, particularly the hands and feet.

Frequent Infections: Sickle-shaped red blood cells harm the spleen, which is in charge of recycling red blood cells as well as storing platelets and white blood cells. As a result, the immune system is weakened, and the body is more vulnerable to infections.

Periodic episodes of pain: 'Crises,' or periodic episodes of pain, occur when sickle-shaped red blood cells obstruct blood flow. Pain is felt in the muscles, bones, joints, chest, and other areas, and it might linger for several hours.

Impaired growth/development: Red blood cells are in charge of the body's oxygen and nutrition delivery. Growth and development are hampered by a lack of red blood cells caused by sickle cell disease.

Impaired vision: Sickle-shaped red blood cells can sometimes obstruct the tiny blood arteries of the eye, causing significant damage to the retina and, as a result, visual impairment.

Genealogy of the disease

The sickle-cell anaemia gene is passed down from generation to generation in a genetic pattern known as Autosomal-Recessive Inheritance. This means that for the kid to be impacted with the disease, both parents must be 'carriers,' and both mother and father must pass on the defective gene. When only one parent is a carrier, the kid may receive 'the sickle cell trait' from that parent, becoming a carrier with one faulty haemoglobin gene (HbS) and one normal haemoglobin gene (HbA). Carriers or those with sickle-cell trait do not experience sickle-cell anaemia symptoms. Their blood, on the other hand, will contain both typical biconcave and sickle-shaped red blood cells.

Sickle cell Anaemia Treatment

Treatment for sickle cell anaemia is typically targeted at alleviating symptoms and preventing complications. Anyone suffering from this disease must have their red blood cell count and health checked, which is why regular check-ups with a licenced doctor are critical. The following are some popular treatments for sickle cell anaemia symptoms:

Medication: Medications used to treat sickle-cell anaemia include:

1. Antibiotics: Children with sickle cell anaemia may be given antibiotics such as penicillin as early as 2 months of age and may continue to take the medications until they are 5 years old. Antibiotics aid in the prevention of potentially fatal illnesses such as pneumonia and jaundice. Adults might also be given these antibiotics as a prophylactic precaution against certain infections.

2. Pain relievers: People suffering from Crises or recurring episodes of pain, which is one of the most noticeable symptoms of Sickle cell anaemia, may be given pain relievers.

3. Hydroxyurea: It can be used on a daily basis to reduce discomfort caused by crises. This medication has been shown to increase the body's production of foetal haemoglobin, a kind of haemoglobin seen in infants that helps prevent the formation of sickle cells. Long-term usage of hydroxyurea, on the other hand, may result in certain serious side effects. As a result, it is critical to consult a doctor before taking this medication and to use it only as advised by a licenced healthcare expert and doctor.

Blood Transfusions: Regular blood transfusions help to maintain the red blood cell count under control, allowing the symptoms of anaemia to be managed. People who have sickle cell anaemia are at a higher risk of having a stroke. Blood transfusions can also help to reduce this danger and so extend a patient's life.

Vaccinations: Sickle-cell anaemia weakens the immune system, making the patient more vulnerable to diseases. Childhood vaccines help reduce the chance of developing life-threatening diseases, especially in children with sickle cell anemia

Supplemental Oxygen: Adding oxygen to the blood and improving circulation are two benefits of using supplemental oxygen through a breathing mask. It is especially beneficial when the patient has acute chest syndrome or a sickle-cell crisis.

Bone marrow transplant: The bone marrow is the primary source of red blood cells. As a result, a bone marrow transplant is the most effective means of treating sickle-cell anaemia, in which the patient's impacted, sickle-cell generating bone marrow is replaced with healthy bone marrow that generates normal red blood cells.

Bone marrow transplantation is a viable and promising treatment option for haematological illnesses such as sickle cell anaemia. The faulty bone marrow is replaced with healthy bone marrow transplanted from a matching donor in this approach. As a result, the new healthy bone marrow will create healthy and efficiently functioning red blood cells rather than the sickle-shaped red blood cells that were initially produced by the patient's bone marrow.

Finding an appropriate donor for the transplantation candidate is one of the most crucial aspects of the process. The treatment process begins with tests to see if the donor and patient have a tissue match. The doctor removes healthy cells from the donor's bone marrow and injects them into the patient's body via an IV tube during this procedure. When the injected cells continue to operate normally in the recipient's body, it is declared to be a match, and the bone marrow transplant is performed after a few more comparable tests.

Bone marrow transplants are the only viable solution for sickle cell disease in India. This approach is highly effective in around 90% of cases involving youngsters with the disease. Certain medications must be taken to reduce the chance of rejection of the transplanted bone marrow.
