Normal and Sickle Hemoglobin
What Is Sickle Cell Anemia?  
Erythrocytes (RBCs) hereditary condition known as sickle cell disease (SCD) causes sickle cell anemia (RBCs). Erythrocytes often have a disc shape that makes it possible for them to pass through capillaries which is even  the smallest blood arteries. But in this condition, the RBCs have an unusual crescent form that resembles a sickle. Due to their sticky, inflexible nature and propensity for becoming stuck in tiny capillaries, they prevent blood from reaching various sections of the body. Pain and tissue damage may result from this genetic disorder.

Information about sickle cell anemia:
An mutation in the haemoglobin gene, which codes for the blood protein that carries oxygen, is the primary pathology of sickle cell disease. About 8% of African Americans have the sickle cell disease gene, making them the group most likely to have the sickle cell variant of this gene. Different haemoglobin gene anomalies exist in other locations, such as India and the Middle East, and they cause a similar pattern of disease.

What are the types of sickle cells?
Sickle cell illness can take many different forms. 
The majority include: 
  1. Sickle Hemoglobin-C Disease (SC)
  2. Sickle Beta-Plus Thalassemia, 
  3. Sickle Cell Anemia (SS) 
  4. 5.Sickle Beta-Zero Thalassemia and 
  5. Sickle Hemoglobin-D Disease.
Sickle Cell Anemia (SS) is a condition that results when a kid gets one substitution beta globin gene (the sickle cell gene) from each parent (SS). 

Chronic Sickle Cell Disease (SC): A slightly different alteration in the beta globin genes of people with Sickle Hemoglobin-C Disease (SC) causes them to manufacture both hemoglobin C and hemoglobin S.

Sickle beta-plus thalassemia: This condition affects the expression of the beta globin gene. Less beta protein is produced, which results in smaller red blood cells. Haemoglobin S beta thalassemia is a condition that can be inherited if the Hb S gene is present. The symptoms are not as bad. 

Hemoglobin-D Sickle Cell Disease: Research has revealed that hemoglobin D, a distinct beta globin gene replacement, interacts with the hemoglobin sickle gene 

The "Sickle Hemoglobin-O Disease" Sickle hemoglobin interacts with hemoglobin O, a different kind of beta globin gene replacement.

Sickle cell anemia causes:
Hemoglobin, a substance found in red blood cells, is the basic cause of sickle cell anemia. Each red blood cell's hemoglobin molecules transport oxygen from the lungs to the organs and tissues before returning carbon dioxide for elimination by the lungs. Sickle cell anemia causes a disruption in this mechanism. Some hemoglobin molecules may group together after losing their oxygen to form long, rod-like structures that stiffen and take on a sickle shape, and gene mutations can result in the inheritance of one hemoglobin S gene from each parent.

"Sickle cell anemia symptoms" 
  1. Yellow eyes
  2. Painful hand and foot swelling 
  3. Repeated episodes of pain 
  4. Steady growth 
  5. Stroke 
  6. Anemia (looking pale) 
  7. Dark urine
Testing and diagnosis of sickle cell anemia:
1. Hemoglobin S, the defective form of hemoglobin that causes sickle cell anemia, can be detected through a blood test. 

2. The diagnosis of sickle cell disease in an unborn child can be made by taking an amniotic fluid sample and testing it for the sickle cell gene. 

3.DNA analysis: This test is used to look at changes and mutations in the genes that make up the components of hemoglobin. It can be used to find out if a person has two copies of the Hb S mutation, one copy of the mutation, or two separate mutations in their hemoglobin genes (e.g., Hb S and Hb C).

Recent trends in medication and treatment:
1. Intravenous fluid rehydration aids in the normalization of red blood cells. If you're dehydrated, your red blood cells are more prone to swell and take on the sickle shape. 

2. Since the stress of an infection can cause a sickle cell crisis, treating underlying or accompanying infections is a crucial part of managing the crisis. An infection could develop as a crisis's side effect. 

3.Blood transfusions enhance the delivery of nutrients and oxygen when necessary. Patients receive packed red cells that have been extracted from donated blood.

4. An oxygen mask is used to administer extra oxygen. It facilitates breathing and raises blood oxygen levels. 
5.During a sickle crisis, morphine and other painkillers are administered to alleviate the agony. 

6. Hydroxyurea (Droxia, Hydrea) promotes fetal hemoglobin production. The necessity for blood transfusions might decline. 

7.Vaccinations can assist in preventing illnesses. Immunity is typically reduced in patients. 

8.Sickle cell anemia has been treated with a bone marrow transplant.

Sickle cell anemia prevention:
1. Consuming lots of water (hydration). 
2. Avoiding temperatures that are too hot or too cold. 
3. Steering clear of environments with low oxygen levels, such as extreme altitudes, military boot camp, or rigorous athletic training. 
4.Getting enough sleep and stopping to rest frequently when working out. 
5. Utilizing the drug hydroxyurea. A doctor must do routine checks on patients using hydroxyurea to make sure the proper dosage is administered for the desired outcome.
