An analysis of diagnosis and treatment in patients with cystic fibrosis

Many different defects can affect the CFTR gene. The type of defect is associated with the severity of cystic fibrosis. The damaged gene is passed on to the child from their parents.

The most common types of cystic fibrosis testing include taking a blood sample for genetic testing or conducting a sweat test.

High salt presence can signal cystic fibrosis. The United States now requires screening of newborns for cystic fibrosis through testing blood samples for abnormal levels of pancreatic chemicals called immunoreactive trypsinogenor IRT.

In some cases, pregnant women can have their babies tested before birth through amniocentesis or a biopsy of the placenta, called chorionic villus sampling CVS.

This fluid can be then tested for cystic fibrosis. During CVS, a needle is used to remove a small amount of placenta which is then evaluated for cystic fibrosis and other genetic diseases. If you have been diagnosed with cystic fibrosis, your doctor may evaluate your condition using a stool test, spirometry or sputum culture.

The following imaging tests also may be ordered: Chest or abdominal computed tomography CT scan: These exams use special x-ray equipment and computers to produce many detailed images of the inside of the lungs or intestines.

These images can help determine the severity of cystic fibrosis by looking at the amount of mucus as well as looking for dilated airways in the lungs. The test can also look for infection.

This test uses ionizing radiation. See the Safety page for more information about CT. This exam uses a small dose of ionizing radiation to produce images to evaluate for dilated airways containing mucus and also to evaluate lung infections that need to be treated with antibiotics.

Chest x-rays are used periodically to observe changes in patients with cystic fibrosis and rule out other respiratory conditions such as pneumonia or a collapsed lung.

See the Safety page for more information about x-rays. Chest or abdominal magnetic resonance imaging MRI: These imaging exams use a powerful magnet, radio waves and a computer to produce detailed pictures of the lungs and digestive tract.

Although chest x-ray or CT is used more commonly for this disease, MRI can help assess damage caused by cystic fibrosis. This imaging test uses a small probe, gel, and high-frequency sound waves, to produce pictures of the upper abdomen.

It evaluates the pancreas, liver, and gallbladder, all of which are affected by cystic fibrosis. CT of the sinuses: This exam combines special x-ray equipment and a computer to produce multiple images of the paranasal sinus cavities.

It can help identify unilateral nasal polyps, which are common in patients with cystic fibrosis. While there is no cure for cystic fibrosis, your doctor may recommend one or more of the following to help relieve symptoms and improve quality of life: Lifestyle changes such as better nutrition, use of vitamins, increased physical activity, avoiding the use of tobacco and avoiding second hand smoke.

Medications such as antibiotics and inhaled medicines can help open the airways and clear them of mucous and infection.(See "Cystic fibrosis: Genetics and pathogenesis" and "Cystic fibrosis: Clinical manifestations and diagnosis".) The treatment of CF lung disease is experiencing a period of rapid evolution, supported by well-designed clinical trials and improved understanding of the .

Survival analysis of cystic fibrosis (CF) patients according to clinical severity in the first 3 years of life and diagnosis. Temporal associations among energy intake, plasma linoleic acid, and growth improvement in response to treatment initiation after diagnosis of cystic fibrosis.

Aug 22,  · Black patients with cystic fibrosis are younger at diagnosis and have poorer nutritional status and pulmonary function than white patients with cystic fibrosis. Whether this is genetic or due to socioeconomic factors is unclear; low socioeconomic status is associated with significantly worse pulmonary outcomes in patients with cystic fibrosis.

Sweat tests may also be ordered for kids, teens and adults with a family history of cystic fibrosis or symptoms of the disorder.

Symptoms and signs include failure to grow, repeated lung infections, and digestive problems. of greater than 40 mEq/L in infants are suggestive of cystic fibrosis, and values greater than 60 mEq/L in children indicate the presence of cystic fibrosis.

A stool analysis can indicate the presence of steatorrhea (undigested fat) and azotorrhea (foul-smelling from protein). The objective of this review was to address current concepts related to the clinical impact, diagnosis, and treatment of Pseudomonas aeruginosa infections in patients with cystic fibrosis.

For the preparation of this review, the authors defined a group of questions that would be answered in accordance with the principles of PICO–an acronym.
