Patient Resources
CF is caused by defective gene. Millions of Americans carry this defect gene, but do not have any symptoms. This is because a person must inherit two defective copies of the gene - one from each parent - in order to show symptoms.
SYMPTOMS | DIAGNOSIS | TREATMENTS
► Symptoms
Symptoms are usually (but not always) recognized by age 2. Symptoms seen in infancy include:
- Delayed growth
- Failure to gain weight normally in childhood
- No bowel movements in the first 24-48 yours of life
- Salty-tasting skin
Other symptoms related to the gastrointestinal tract that may occur from infancy onward include:
- Belly pain from severe constipation
- Increased gas, bloating, or a belly that appears swollen (distended)
- Nausea and loss of appetite
- Stools that are pale or clay colored, foul smelling, have mucus, or that float
- Weight loss
Symptoms that may occur from childhood onward related to the lungs and sinuses include:
- Coughing or increased mucus in the sinuses or lungs
- Fatigue
- Nasal congestion caused by nasal polyps
- Recurrent episodes of pneumonia
- Sinus pain or pressure caused by infection or polyps
Symptoms that may be noticed later in life include:
- Infertility (in men)
- Repeated inflammation of the pancreas (pancreatitis)
- Respiratory symptoms
► Diagnosis
CF can be diagnosed when characteristic clinical symptoms are present with one or more of the following:
- Immunoreactive trypsinogen (IRT) - This is now a standard newborn screening test for CF. A high level of IRT suggests possible CF and requires further testing.
- Sweat chloride test is the standard diagnostic test for CF. A high salt level in the patient's sweat is a sign of the disease.
- Cystic fibrosis gene analysis testing.
► Treatments
CF treatment encompasses individualized therapies for each organ system involved in a particular patient. Some of the therapies that may be used include:
Lung disease
- Chest therapies to improve mucous clearance. These can include a percussion vest, manual chest percussion, A-capella, Flutter valve, or TheraPEP device. These therapies should be done 1-4 times per day depending on lung status
- DNAse enzyme therapy (Pulmozyme®) to thin mucous and make it easier to cough up
- Inhaled bronchodilators (albuterol, levalbuterol, others) to help open the airways
- Inhaled hypertonic saline to improve mucous clearance
- Inhaled antibiotics
- Antibiotics by mouth or through veins to decrease bacterial colonization in the airways
- Flu vaccine yearly
- Regular aerobic exercise
- Pneumococcal vaccine
- Oxygen therapy if needed if lung disease worsens
- Lung transplantation may be needed as lung disease worsens
Gastrointestinal and nutritional disease
- A special diet high in protein and calories for older children and adults
- Pancreatic enzymes to help absorb fats and protein
- Vitamin supplements, especially vitamins A, D, E, and K
Diabetes
- Glucose monitoring and insulin therapy
General health recommendations
- Avoid smoke, dust, dirt, fumes, household chemicals, fireplace smoke, and mold or mildew
- Drink plenty of fluids. This is particularly true for infants, children, in hot weather, when there is diarrhea or loose stools, or during extra physical activity
- Exercise two or three times each week. Swimming, jogging, and cycling are good options
