Cystic Fibrosis Center
The Cystic Fibrosis Center at Stony Brook is an accredited Cystic Fibrosis Center by the Cystic Fibrosis Foundation. Due to this status, the Center follows guidelines set forth by the Cystic Fibrosis Foundation.
What is Cystic Fibrosis?
Cystic Fibrosis is a genetic disease. An individual must inherit two defective copies of the Cystic Fibrosis gene -- one from the mother and one from the father -- to have Cystic Fibrosis. Individuals who only have one defective Cystic Fibrosis gene are call Cystic Fibrosis "carriers" and have no Cystic Fibrosis symptoms.
What happens to a person with Cystic Fibrosis?
A person with Cystic Fibrosis has a problem with the transport of salt and fluid within the cells lining most body organs such as lungs and pancreas. The body produces abnormally thick, sticky mucus. In the lungs, thick mucus clogs the air tubes causing respiratory symptoms (cough and trouble breathing) and repeated infections. In the pancreas, the tubes are blocked preventing the enzymes to reach the intestines. Without enzymes, food (especially fat) is not properly digested.
What are the symptoms of Cystic Fibrosis?
Cystic Fibrosis presents with a variety of symptoms. The most common are repeated respiratory infections, persistent cough and wheezing, and poor weight gain with greasy, foul smelling stools. A Cystic Fibrosis person also has salty tasting skin because of a high level of salt in the sweat. This is the basis for the sweat test to diagnose Cystic Fibrosis.
What increases your risk of Cystic Fibrosis?
Each time two carriers conceive a child, there is a 25% chance that the child will have Cystic Fibrosis; a 50% chance that the child will be a carrier; and a 25% chance that the child will be a non-carrier.
There are about 30,000 people who have Cystic Fibrosis in the United States. Another 6 million are Cystic Fibrosis carriers. Cystic Fibrosis affects 1 out of every 3,000 Caucasians. The risk is lower in other races: 1 out of 13,000 African Americans and 1 out of every 32,000 Asian Americans.
How is Cystic Fibrosis diagnosed?
A physician usually suspects Cystic Fibrosis based on symptoms or a family history of Cystic Fibrosis. The standard diagnostic test for Cystic Fibrosis is the sweat test. This is a simple and painless test.
Genetic testing is available for Cystic Fibrosis. This is a blood test that looks for defective Cystic Fibrosis genes (called Cystic Fibrosis mutations). It is a positive test when two Cystic Fibrosis mutations are found. A negative test does not totally rule out Cystic Fibrosis.
Who treats a Cystic Fibrosis patient?
A Cystic Fibrosis patient is referred to a Cystic Fibrosis Center after diagnosis. There are about 110 accredited Cystic Fibrosis Centers in the US.
A person with Cystic Fibrosis is treated at the Cystic Fibrosis Center every 3 months or more often as nedded. The primary care physician is also involved in the care of the Cystic Fibrosis patient.
Blood tests, chest x-rays, pulmonary function testing, and sputum cultures are obtained on a regular basis.
How do you treat Cystic Fibrosis?
The treatment of Cystic Fibrosis depends upon the stage of the disease and which organs are afected. Chest physicial therapy is very iimportant to optimize clearance of airway secretions. Nebulizer treatments are given to help open the airways and control the lung infection. In addition, regular nutritional evaluation is important to provide a regimen for an adequate Cystic Fibrosis diet, enzyme and vitamin supplementation, as well as weight and growth monitoring.
Antibiotics are used to treat lung infections and may be administred orally by inhalation or intravenously depending on the particular need.
How do you prevent and cure Cystic Fibrosis?
Currently, there is no way to prevent Cystic Fibrosis and to cure Cystic Fibrosis. Genetic counseling is available to determine the family's chances of passing Cystic Fibrosis to their children. Prospective parents can opt for genetic testing as well as prenatal testing.
Research is ongoing in the hope to find a cure for Cystic Fibrosis in the future.
