It is desirable that you get familiar with the sickle cell anemia pathophysiology before seeking treatment in a foreign land since it will greatly influence the course of your treatment decision making, the outcome of the treatment you are likely to get, and long term care provisions. Here's why it matters:
Empowers Choices of Treatment on Facts
Sickle cell is a mutation of the hemoglobin gene attributing to the production of abnormally shaped red blood cells. Such sickled cells have the ability to obstruct the circulation of blood in blood vessels and cause complications.
With this information, patients and caregivers can learn more of why some cases may be prescribed treatments such as blood transfusion, drugs (such as Hydroxyurea), or bone marrow transplant.
Helps Select the appropriate Country and Hospital
Various nations have different degrees of experience in the management of sickle cell disease. For example:
More complicated treatments such as stem cell or bone marrow transplant can be more affordable in a special facility.
Certain nations are more supportive in care and management of crisis.
Knowledge of the disease aids in determining the ability of a hospital in a foreign country to treat complications, such as pain crisis, infections, or damage of organs.
Accurate Cost Planning
Treatment in foreign countries may differ greatly in terms of its prices based on the complexity of the disease. The patients with severe complications might need:
Frequent hospitalizations
Intensive monitoring
Advanced procedures
Understanding the pathophysiology would give you an idea of whether you will require simple management or expensive interventions.
Enhances Communication with Physician
As you learn about how sickle cell disease impacts your body, you will be able to:
Ask better questions
Know of risks and benefits of treatment.
Be actively involved in decision-making.
This is particularly relevant in the case of turning to doctors in another country whose medical systems and procedures can be different.
Gets Ready to Potential Complications
Sickle cell anemia may cause severe problems including:
Stroke
Acute chest syndrome
Organ damage
Knowing the pathophysiology allows you to identify signs and symptoms of the condition and get early treatment – even when you're traveling abroad.
Promotes Improved Travel and Post-Treatment Outcomes
Travel can in itself cause complications because of:
Dehydration
Low oxygen (in particular, during flights).
Stress
Preventive measures can be taken by the patients with adequate knowledge, and continuity of post-discharge care ensured.
Sickle cell disease is inherited and occurs when a mutation affects the β-globin gene of the hemoglobin, leading to the production of a protein called hemoglobin S. The pathophysiology of this disease is a complicated sequence of:
Genetic mutation and the hemo-globin molecule
Source: Restriction site mutation, 11 β -globin gene.
Findings: 1 Valine residue at 6-position in the 8 globin protein has replaced a glutamic acid residue.
Effect: They don’t produce normal adult haemoglobin, they produce sickle haemoglobin.”
Polymerization of Hemoglobin S
When oxygen is low, HbS polymerizes and forms a long, stiff rod.
That causes red blood cells to be comet-shaped or sickled.
Red Blood Cell Sickling
Sickled RBCs are:
Hard and less flexible
Susceptible to hemolysis (breaking up prematurely)
Have a shorter life span (~10–20 days compared to 120 days for healthy RBCs)
Vaso-occlusion
Sickled cells:
Become trapped in small capillaries
Induce obstructions (vaso-occlusion) in blood vessels
Lead to tissue ischemia, pain (sickle cell crises), and organ injury
Hemolysis and Anaemia
Progressive destruction of sickle cells results in:
Levels of hemolytic anemia
Hyperbilirubinemia
Gallstones
Inflammation and the Dysfunction of Endothelial Cells
Ischemia and vaso-occlusion lead to:
Inflammatory cytokines
Endothelial activation and damage
More adhesion of leukocytes and sickled cells to blood vessel walls
Sickle cell anemia complications
Sickle Cell Anemia is an incurable hereditary condition of the blood that is likely to cause severe complications otherwise. International patients also go to India in large numbers to receive improved and affordable care that includes long-term medical care and curative transplant procedures.
Sickle Cell Anemia Complications:
Pain Crises
Severe Infections
Stroke
Acute Chest Syndrome
Chronic Anemia & Fatigue
Kidney Damage
Bone & Joint Problems
Vision Problems
Growth and puberty delayed
Treatment options
Medical Management:
Hydroxyurea Therapy
Enhances fetal hemoglobin (HbF).
Minimizes crises of pain and hospitalization.
Blood Transfusions
Means of treating serious anemia and stroke prevention.
Exchange transfers in major Indian capitals.
Vaccines and antibiotics
Prevent a severe infection
Of particular significance in children.
Developed and Palliative Therapies:
Bone marrow/ Stem Cell Transplant
Only proven cure
Optimal success in children that are matched siblings.
In India transplant centers with specialization.
Gene Therapy (Limited Centers)
New treatment in the chosen hospitals.
Expensive and scarce.
Supportive Care:
Pain management programs
Oxygen therapy
Nutritional support
Psychological counselling
Guidelines on malaria prevention.
Conclusion
Knowledge of the Sickle Cell Anemia pathophysiology is important for the patient to be treated at foreign as it is the basis on which safe, informed and effective decisions can be made regarding healthcare. A solid understanding of the underlying mechanisms of how abnormal hemoglobin causes red blood cell sickling, vaso-occlusion, hemolysis, and systemic complications allows patients to make better decisions about treatments — from medical therapies such as Hydroxyurea to curative options like stem cell transplantation. This also allows for a more accurate estimation of costs, a better choice of country and specialty hospital, and improved communication with foreign medical providers. It also enables the patient to predict complications and to better take travel- and home-related risks into consideration, and to maintain follow-up care at home after the patient returns. Ultimately, the knowledge of disease process allows not only good clinical outcome but also safe and confident navigation by the patients and the families in the more complex global health care system.
