Background

Cystic fibrosis is an inherited disease that causes thick, sticky mucus to build up in the lungs and digestive tract. It is the most common type of chronic lung disease in

children and young adults, and may result in early death.

Quit

Causes

Cystic fibrosis (CF) is caused by a defective gene which tells the body to produce abnormally thick and sticky fluid, called mucus. This mucus builds up in the breathing passages of the lungs and the pancreas, the

organ that helps to break down and absorb food.

Quit

Facts

Most children are diagnosed with CF by their 2nd birthday. A small number, however, are not diagnosed until age 18 or older. These patients usually have a milder form of the disease.

Overview

Millions of Americans carry the defective CF gene, but do not have any symptoms. That's because a person with CF must inherit two defective CF genes -- one from each parent. An estimated 1 in 29 Caucasian Americans have the CF gene. The disease is the most common, deadly, inherited disorder affecting Caucasians in the United States. It's more common among those of Northern or Central European

descent.

Symptoms

No bowel movements in first 24 to 48 hours of life Stools that are pale or clay colored, foul smelling, or that float Infants may have salty-tasting skin Recurrent respiratory infections, such as pneumonia or sinusitis Coughing or wheezing Weight loss, or failure to gain weight normally in childhood Diarrhea Delayed growth Fatigue

Quit

Treatment

Antibiotics for respiratory infections. Pancreatic enzymes to replace those that are missing. Vitamin supplements, especially vitamins A, D, E, and K. Inhaled medicines to help open the airways. DNAs enzyme replacement therapy to thin the mucus and makes it easier to cough

up. Pain relievers. Research has shown that the pain reliever ibuprofen may slow lung

deterioration in some children with cystic fibrosis. The results were most dramatic in children ages 5 to 13.

Postural drainage and chest percussion. Lung transplant may be considered in some cases.

Preventing

There is no way to prevent cystic fibrosis. Screening of family members of a cystic fibrosis patient may detect the cystic fibrosis gene in between 60 and 90% of carriers, depending on the test used.

Quit

Expectations

Disease registries now show that 40% of patients with cystic fibrosis are over age 18.

Today, the average life span for those who live to adulthood is approximately 35 years, a dramatic increase over the last three decades.

Death is usually caused by lung complications.

Quit

Risks

This collection of sticky mucus results in life-threatening lung infections and serious digestion problems. The disease may also affect the sweat glands and a man's reproductive system.
