    Early detection of the disorders and prompt delivery of penicillin to prevent pneumococcal infections has improved the survival of newborn babies with sickle cell disease, said Dr Streetly. The antenatal arm of the programme is also serving to alert carriers to the disease and offers couples at risk of passing on the diseases the option of fetal screening.
 
    The detection rate of the disorders is similar to that predicted but higher than what will become the national average because of the high prevalence of the disorders in the areas primarily targeted by the programme, which include London and the West Midlands, said Dr Streetly.
 
    "Sickle cell disease and thalassaemia have a similar prevalence among newborn babies as cystic fibrosis, but there is far less awareness of these disorders among both doctors and the general public," she said. "One of the aims of the programme is to raise awareness of these disorders and improve understanding of how it is carried and passed on." (文章出处：《英国医生杂志》) 相关问答：

Sickle Cell Disease [转贴 2007-11-24 22:11:17]    
 字号：大 中 小 
Sickle Cell Disease is a group of inherited red blood cell disorders. Normal red blood cells are round like doughnuts, and they move through small blood tubes in the body to deliver oxygen. Sickle red blood cellsbecome hard, sticky and shaped like sickles used to cut wheat. When these hard and pointed red cells go through the small blood tube, they clog the flow and break apart. This can cause pain, damage and a low blood count, or anemia.
 
What makes the red cell sickle?
There is a substance in the red cell called hemoglobin that carries oxygen inside the cell. One little change in this substance causes the hemoglobin to form long rods in the red cell when it gives away oxygen. These rigid rods change the red cell into a sickle shapeinstead of the round shape.
 
How do you get sickle cell anemia or trait?
You inherit the abnormal hemoglobin from your parents, who may be carriers with sickle cell trait or parents with sickle cell disease. You can not catch it. You are born with the sickle cell hemoglobin and it is present for life. If you inherit only one sickle gene, you have sickle cell trait. If you inherit two sickle cell genes you have sickle cell disease.
 
Is Sickle Cell only in African Americans?
 
Sickle cell is in many nationalities including African Americans, Africans, Arabs, Greeks, Italians, Latin Americans,  and those from India. You can be Caucasian and have sickle cell disease or trait. All races should be screened for this hemoglobin at birth.
 
How can I be Tested?
 
A simple blood test called the hemoglobin electrophoresis can be done by your doctor or local sickle cell foundation. This test will tell if you are a carrier of the sickle cell trait or if you have the disease.
 
Newborn Screening
 
Most States now perform the sickle cell test babies are born. The simple blood test will detect sickle cell disease or sickle cell trait . Other types of traits that may be discovered include:
 
Hemoglobin C trait
 
Hemoglobin E trait
 
Hemoglobin Barts - which indicates an alpha thalassemia trait
 
Beta thalassemia trait
 
What is sickle cell trait?
 
Sickle cell trait is a person who carries one sickle hemoglobin producing gene inherited from their parents and one normal hemoglobin gene. Normal hemoglobin is called type A. Sickle hemoglobin called S. Sickle cell trait is the presence of hemoglobin AS on the hemoglobin electrophoresis. This will NOT cause sickle cell disease. Other hemoglobin traits common in the United States are AC and AE traits.
 
Are there different types of sickle cell disease?
 
There are three common types of sickle cell disease in the United States.
 
Hemoglobin SS or sickle cell anemia
Hemoglobin SC disease
Hemoglobin sickle beta-thalassemia
Each of these can cause sickle pain episodes and complications, but some are more common than others. All of these may also have an increase in fetal hemoglobin which can protect the red cell from sickling and help prevent complications. The medication hydroxyurea also increases fetal hemoglobin.
 
What are the Complications?
 
Complications from the sickle cells blocking blood flow and early breaking apart include:
 
pain episodes
strokes
increased infections
leg ulcers
bone damage
yellow eyes or jaundice
early gallstones
lung blockage
kidney damage and loss of body water in urine
painful erections in men (priapism)
blood blockage in the spleen or liver (sequestration)
eye damage
low red blood cell counts (anemia)
delayed growth
What can be done to help prevent these complications?
 
Sickle cell patient should be under the care of a medical team that understands sickle cell disease. All newborn babies detected with sickle cell disease should be placed on daily penicillin to prevent serious infections. All of the childhood immunizations should be given plus the pneumococcal vaccine. Parents should know how to check for a fever because this signals the need for a quick medical checkup for serious infection. The following are general guidelines to keep the sickle cell patient healthy:
 
Taking the vitamin folic acid (folate) daily to help make new red cells
Daily penicillin until age six to prevent serious infection
Drinking plenty of water daily (8-10 glasses for adults)
Avoiding too hot or too cold temperatures
Avoiding over exertion and stress
Getting plenty of rest
Getting regular check-ups from knowledgeable health care providers
Patients and families should watch for the following conditions that need an urgent medical evaluation:
 
Fever
Chest pain
Shortness of Breath
Increasing tiredness
Abdominal swelling
Unusual headache
Any sudden weakness or loss of feeling
Pain that will not go away with home treatment
Priapism (painful erection that will not go down)
Sudden vision change

Genetic fix for sickle cell disease?

Researchers have shown that it could one day be possible to cure sickle cell disease, a genetic disorder affecting about a million people, mostly in developing countries. The results are published in Nature Biotechnology this month (January 2006).
 
Lead researcher Michel Sadelain, of the US-based Memorial Sloan Kettering Cancer Center, warns that the research is still at an early stage, but says it offers hope for tackling what is currently a virtually incurable disease.
