Sickle Cell Disease

National Mission to Combat Sickle Cell Disease

India has launched a significant initiative, the National Sickle Cell Anaemia Elimination Mission, aimed at eradicating Sickle Cell Anaemia from the country.

As part of this mission, over 1 crore people have already undergone screening for Sickle Cell Disease (SCD), highlighting the scale of the public health challenge.

Understanding Sickle Cell Disease (SCD)

Sickle Cell Disease (SCD) is a collective term for a group of inherited red blood cell (RBC) disorders. These conditions are genetic, meaning they are passed down from parents to their children.

In individuals with SCD, the hemoglobin is abnormal. This abnormality causes the red blood cells to become rigid and sticky.

Crucially, these affected RBCs also change their shape, resembling a C-shaped farm tool known as a “sickle.” This characteristic shape is where the disease gets its name.

Common Symptoms of SCD

The symptoms of Sickle Cell Disease can vary significantly among individuals, but several common manifestations are observed.

• Chronic Anemia: This is a persistent lack of healthy red blood cells, leading to symptoms such as severe fatigue, general weakness, and noticeable paleness of the skin.
• Painful Episodes (Sickle Cell Crisis): These are hallmark symptoms, characterized by sudden and intense pain. The pain can affect various parts of the body, including the bones, chest, back, arms, and legs.
• Delayed Growth and Puberty: Children and adolescents with SCD may experience delays in their physical development, including slower growth rates and a postponed onset of puberty.

Treatment Approaches for SCD

While there is no universal cure for Sickle Cell Disease, several treatments are available to manage symptoms, prevent complications, and improve quality of life.

• Blood Transfusions: This treatment involves receiving healthy blood from a donor. It helps to alleviate anemia and significantly reduces the frequency and severity of pain crises.
• Hydroxyurea: This is a specific medication prescribed to patients with SCD. It works by reducing the occurrence of painful episodes and preventing some of the long-term complications associated with the disease.
• Bone Marrow or Stem Cell Transplantation: For some patients, particularly children, bone marrow or stem cell transplantation can offer a curative option. This procedure replaces diseased bone marrow with healthy cells.

Government Initiatives Against SCD

The Indian government has undertaken specific measures to address the burden of Sickle Cell Disease within the country.

In 2016, the government released comprehensive technical operational guidelines. These guidelines are designed for the effective prevention and control of sickle cell anaemia across the nation.
