This condition leads to expansion of alveoli, where air trapping occurs and, over time, causes the barrel-shaped chest that is also common in patients with emphysema.Destruction of the pulmonary parenchyma leads to increased pulmonary arterial pressure that, in turn, causes right-sided heart failure or cor pulmonale.
If 2 persons who are heterozygous for have a child, the child can have cystic fibrosis.
According to estimates, approximately 7 to 10 million cystic fibrosis carriers exist in the United States who are totally unaware that they carry a mutated A white American couple with no family history of cystic fibrosis has a 1 in 2500 chance of having a child with cystic fibrosis.
As mentioned earlier, the gene for cystic fibrosis is on the long arm of chromosome 7.
Pulmonary function testing is a method that may be helpful in establishing data that will assist in predicting deterioration in clinical status in patients with cystic fibrosis.
The increased work of breathing can include any of the following: tachypnea, irregular breathing pattern, diaphoresis, flared nares, pursed lip breathing, intercostal muscle retractions, and use of accessory muscles.
the gene associated with cystic fibrosis, encodes the protein cystic fibrosis transmembrane conductance regulator (also abbreviated CFTR, but not italicized).
The gene was identified in 1989 and is found at 7q31.2, the long arm (q) of chromosome 7 at position 31.2.As a result, the mucus thickens and becomes sticky and obstructs the various pathways.This obstructive process also prevents bacteria from being cleared from the cells and thus increases the potential for infection.This difference leads to increased numbers of asialo GM1 molecules, which are receptors for bacterial respiratory organisms, and thereby results in increased binding of ), which is very resistant to most antibiotics.As obstruction of the airway increases, it becomes more difficult for air to pass during exhalation.This life-threatening situation is further exacerbated by coagulopathies often caused by malabsorption of vitamin K and repeated use of some antibiotics.
