Cayman Islands is joining the United Nations on Saturday to observe Sickle Cell
Disease World Day.
year is the 100th anniversary of sickle cell disease being officially recognised
as a separate disorder.
December 2008, the United Nations General Assembly adopted a resolution that
recognised sickle cell disease as a public health problem, and the Sickle Cell
Disease World Day was first observed last year in a bid to raise public
awareness of the disease.
Public Health Department is aware of 36 people in the Cayman Islands with
sickle cell disease, and the islands’ hospitals have facilities to diagnose and
cell disease is a chronic disease for which there is no cure, but medical
professionals can treat symptoms. Sickle cell testing is offered to all newborn
babies in Cayman.
has a peer support group called the Sickle Cell Support Group, where family and
patients share experiences in coping with the disease, and educational sessions
are organised for awareness and management of the disease. The group meets
three to four times a year.
someone has sickle cell trait, it is important to know if one’s partner is also
a carrier. If both parents are sickle cell carriers, then with each pregnancy,
there is a 25 per cent risk of having a child with sickle cell disease,” said
Joy Merren, genetics coordinator at the Cayman Islands Health Services
ahead of time can help couples make informed reproductive choices. While sickle
cell trait is mild, sickle cell disease is serious and can potentially affect
every organ of the body,” she added.
cell disease is an inherited chronic disorder that affects red blood cells. It
is seen worldwide and is one of the most common genetic disorders.
cell disease is an inherited blood disorder that affects red blood cells.
People with sickle cell disease have red blood cells that contain mostly haemoglobin*
S, an abnormal type of haemoglobin. Sometimes these red blood cells become
sickle-shaped (crescent shaped) and have difficulty passing through small blood
sickle-shaped cells block small blood vessels, less blood can reach that part
of the body and tissue that does not receive a normal blood flow eventually becomes
normal red blood cell lives approximately 120 days but a sickle cell may only
live 11 or 12 days.
Sickle cell trait?
only one gene is affected, it is called sickle cell trait, or persons are
called sickle cell carriers. Having sickle cell trait means that the person
normally stays healthy and the main significance is that it can be passed on to
one’s children. However, under certain extreme circumstances, a person with the
trait may experience complications as if having sickle cell disease. People
with just the trait cannot later develop the disease.
Inherited sickle cell disorder
a man and a woman are both sickle cell carriers, with each pregnancy, there is
a 25 per cent chance of the child having the disease; 25 per cent chance of the
child being completely free from sickle cell; and a 50 per cent chance of the
child having the sickle cell trait, i.e., being a carrier.
only one parent is a carrier, there is a 50 per cent chance of the child having
the trait; 50 per cent chance of the child being completely free of sickle; and
no chance of the child having the disease.
Sickle cell disease symptoms
jaundice and gallstones due to rapid breakdown of the red blood cells
swelling of fingers and toes in babies
attacks of joints, back and abdomen as there may be damage to the bone marrow
such as pneumonia, may develop
ulcers may develop due to less oxygen to lower legs
Management of sickle cell disease
recommended immunisations plus pneumococcal vaccines
starting from about two months of age to five years of age to help prevent
of symptoms by using medications as needed
acid daily to help make new red cells
