Cystic Fibrosis

A detailed Summary of Cystic Fibrosis


About 1 out of 201 Caucasian people carry at least one of the fatal defective genes that cause cystic fibrosis, CF, or mucoviscidosis (in Europe) although carriers don't show any signs of the disease. Therefore, 10 million people carry the defective gene and don't know it. Consequently, it is one of the most common genetic defect in the United States.

Cystic fibrosis is a autosomal recessive gene. That means that it may, but doesn't always have to skip generations. In order to have this disease, both parents must be carriers. If one parent has Cystic fibrosis and the other one is not a carrier than there is a 100% chance that their child will be a carrier. If one parent has Cystic fibrosis and the other is a carrier than the child has a 50% chance of having CF and a 50% chance of just being a carrier. If both parents are carriers than their child will have a 25% of having CF, a 50% chance of being a carrier and a 25% chance of not being affected at all. CF is common in both male


How does a person know if they have CF? There are many symptoms to this deadly disease including: salty tasting skin, constant coughing, large amounts of mucus, trouble gaining weight, frequent greasy, foul smelling bowel, growths in the nose (nasal polyps) and clubbed or enlarged fingertips and toe tips is another symptom. Now there are many tests that can be done to find put if a person has CF.

There are now many drugs that are in the market and many more that are in development. Treatments mainly depends on what organs are effected. The first new drug therapy in 30 years was approved by the Food and Drug Administration in December of 93'. It's a mucus-thinning drug called Pulmozymec. Pulmozymec has reduced the number of respiratory infections and improved lung function. There is also postural drainage or thumps. This treatment is when the patient is hit on the back and chest with cupped hands to loosen the mucus so it can be coughed up easier. There are many antibiotics that help treat lung
