Members, I am going to attempt to write up regular medical topics which hopefully will be of benefit or interest to those reading. In this opening article on sickle cell, I choose to start off with key points which are definitive of sickle cell anaemia and hope to be able to later look at ways of redress. Any comments are welcomed as would any additions to what is stated hereby.
Sickle cell anemia is a serious condition in
which the red blood cells can become sickle-shaped (that is, shaped like a
“C”).
Sickle-shaped cells don’t move easily
through the blood. They’re stiff and sticky and tend to form clumps and
get stuck in blood vessels. The clumps of sickle cells block blood flow in the
blood vessels, causing pain, serious infections, and organ damage.
Sickle cell anemia is an inherited, lifelong
condition. People who have sickle cell anemia are born with it. They inherit
two copies of the sickle cell gene, one from each parent.
People who inherit a sickle cell gene from one
parent and a normal gene from the other parent have a condition called sickle
cell trait. People with sickle cell trait don’t have the condition, but
they can pass the sickle cell gene on to their children.
Sickle cell anemia affects millions of people
worldwide - most common in people whose families come from Africa,
South or Central America (especially Panama), Caribbean islands, Mediterranean
countries (such as Turkey, Greece, and Italy), India, and Saudi Arabia.
The signs and symptoms of sickle cell anemia are
different in each person. Some people have mild symptoms. Others have very
severe symptoms and are often hospitalized for treatment. The most common signs and symptoms of sickle
cell anaemia are linked to anaemia and pain (also referred to as a "sickle cell
crisis").
Infection is a major complication of sickle cell
anemia. Pneumonia, in particular, can be a life-threatening complication in
children with sickle cell anemia. Routine treatment with penicillin and
vaccinations are used to prevent infection in children.
Strokes are a major complication for children
with sickle cell anemia. Routine screening and early treatment can prevent
strokes.
Early diagnosis of sickle cell anemia is very
important so that children who have the condition can get proper treatment.
Screening tests for sickle cell anemia and sickle cell trait are done on
newborn infants in most parts of the developed world - I am yet to ascertain whether this is the case Uganda as well as other parts of Africa. One blood test used to diagnose sickle cell
anemia looks at how hemoglobin moves in an electric field. This is called
electrophoresis, and it’s usually used to diagnose older children and
adults.
Effective treatments are available to help
relieve the symptoms and complications of sickle cell anemia, but in most cases
there’s no cure. (Some researchers believe that bone marrow transplants
may offer a cure in a small number of cases.)
Sickle cell anemia is treated with medicines,
blood transfusions, and other treatments specific to certain
complications.
Researchers are working to develop new treatments
for sickle cell anemia, including gene therapy and safer and more effective
bone marrow transplants.
If you have sickle cell anemia, take good care of
yourself and see your doctor regularly - also look into genetic counselling as part of family planning.
If your child has sickle cell anemia, you should
learn as much about the condition as possible. This will help you recognize
early signs of problems, such as fever or chest pain, and seek early treatment.
