The risk also is increased in families with a history of CF.
Carrier testing can be done for couples planning a pregnancy or during pregnancy to assess their risk. The test is done on a blood sample. Carrier testing also is available to all pregnant women. If testing shows that a couple is at high risk, more testing can be done during pregnancy to see whether their fetus has CF. If your test results are negative, the chance that you are a CF carrier is small. There are some rare CF gene defects that the test does not detect.
For this reason, you could be told your test result is negative, and you could still be a carrier. The likelihood of this is very small. If the test results show that one partner is a carrier, the next step is to test the other partner. Both parents must be CF carriers for the baby to have CF. If one parent has a negative test results, the chance that the baby will have CF is small. Because the risk is small, if one partner is a carrier but the other has a negative result, no further testing is recommended.
If the father is not available for a carrier test, a genetic counselor may be able to help you decide whether to have prenatal testing of the fetus to see if it has CF. Today, many people with CF achieving their dreams of attending college , pursuing careers, getting married, and having kids.
Watch this video to see how we "count our success in lives" as we continue writing the next chapter in CF together. Although there has been significant progress in treating this disease, there is still no cure and too many lives are cut far too short. The types of CF symptoms and how severe they are can differ widely from person to person. Therefore, although treatment plans can contain many of the same elements, they are tailored to each person's unique needs.
People with CF and their families have expertise in how the disease affects them and how their daily lives affect the way they approach their care. By acknowledging each other's expertise, people with CF, their families, and clinical care teams can work together to develop treatment plans that align personal life goals with health goals.
Accrediting more than care centers. These centers are staffed by dedicated health care professionals who provide expert CF care and specialized disease management. Supporting research to discover and develop new CF treatments and maintaining a pipeline of potential therapies that target the disease from every angle.
Today, the Foundation is focused on developing lifesaving new therapies for larger numbers of people with CF -- including those with rare and nonsense mutations -- and pursuing daring, new opportunities to one day develop a lifelong cure. When a group of parents started the Cystic Fibrosis Foundation in , there were no treatments for cystic fibrosis. These parents set their sights high, to:.
In the following years, the fundraising and commitment of the CF community has enabled the Foundation to support fundamental research in the laboratory that has led to groundbreaking discoveries , including identifying the gene and protein responsible for cystic fibrosis.
By expanding our knowledge of the underlying biology of the disease and its effect on the body, researchers have paved the way for creating new treatments. The Foundation's steadfast commitment to advancing CF research has helped enable more than a dozen new treatments for the disease. We have made incredible progress, including the approvals by the U. Watch this video to see how clinical research has made a difference in the lives of people with CF.
Colonoscopy to monitor for colorectal cancer because of increased risk. Glucose monitoring and testing to check for cystic fibrosis-related diabetes. Lung biopsy to test for specific bacteria. Pancreas function testing, which may include looking at an enzyme called pancreatic elastase-1 in your stool. Pulmonary function tests , which includes checking oxygen levels in your blood and spirometry, which is the most important and widely used tool to assess lung function in cystic fibrosis.
Regular spirometry is used to monitor lung function in people age 6 and older and may be done in children as young as age 3. Respiratory sample smear and culture, which involves taking airway secretion or mucus samples every three months to look for microorganisms in the respiratory tract, and if necessary, treat them. Review of caloric intake, and pancreatic enzyme replacement.
Healthy lifestyle changes. These include the following: Avoiding tobacco smoke, including secondhand smoke. Being physically active to improve lung function. Physical activity helps with airway clearance and improves bone mineral density, muscle strength, flexibility, and posture.
Before starting any exercise program, ask your doctor about what level of physical activity is right for you. Healthy eating to improve overall health. Healthy eating is also important for normal growth in children who have cystic fibrosis. You may need to increase your food or calorie intake by eating more foods or by eating high-energy foods.
A high-sodium eating plan or supplementation with sodium may be recommended at times. Prevent or reduce complications over your lifetime. To help you prevent complications and reduce the risk of infections, your doctor may recommend the following: Continue your treatments, including medicines, supplements, and daily airway clearance techniques. Treating infections and pulmonary exacerbations is important to preserve lung function and slow the progression of disease.
Lung disease is the major source of CF-related complications. Practice good hand hygiene whenever it is appropriate, such as before and after taking medicines and breathing treatments , before you eat, after you use the bathroom, and after blowing your nose.
Wash your hands often with soap or use an alcohol-based hand sanitizer. Receive recommended vaccines, which includes routine immunizations, vaccine for pneumococcus, and an influenza shot every year at the start of flu season. Anyone who lives with you or whom you see often should also get regular vaccines. Treatments for complications.
Your doctor may recommend medicines to treat complications of cystic fibrosis, including: Antibiotics to prevent or treat lung infections and pulmonary exacerbations. Insulin to treat diabetes caused by destruction of the pancreas, if needed. Medicine to help unclog ducts in the liver and improve bile flow. This includes ursodeoxycholic acid. This may improve abnormal liver function blood tests.
Nutritional supplements when healthy eating is not enough. Your doctor may recommend supplements such as calcium, multivitamins, oral pancreatic enzymes, sodium, or vitamin A, D, E, and K. Oxygen therapy to treat low levels of oxygen in the blood. This may improve the ability to be physically active and attend school or work. Surgeries such as lung transplant may help people with advanced lung disease and respiratory failure. Liver transplant may be an option for advanced liver disease such as cirrhosis.
A person who undergoes a lung transplant will also need pulmonary rehabilitation after the surgery. Learn the warning signs of serious complications and have a plan. Call your doctor if you believe you have any of the following: Pulmonary exacerbation, which involves a worsening of lung symptoms, such as more coughing or wheezing, chest congestion, and a change in mucus color.
You may also have weight loss, a poor appetite, or fever. Hemoptysis, which may be a sign that an artery has broken and is bleeding into the airway.
Sudden shortness of breath or chest pain, which may be a sign of a pneumothorax, or collapsed lung. Research for Your Health. Improving health with current research. We studied lung disease in infants and young children diagnosed with cystic fibrosis before they have symptoms through the Early CF Lung Disease program. This may reveal how cystic fibrosis develops, which could lead to interventions that delay or prevent disease progression. Through the Grand Opportunity Exome Sequencing Project GO-ESP , researchers made discoveries about how genes contribute to variations in disease severity between people who have cystic fibrosis.
This may help us find better ways to prevent, diagnose, and treat cystic fibrosis and its complications. Visit the Economic stimulus fuels NIH search for genetic disease signatures for more information.
The NHLBI works toward the prevention of chronic lung diseases, including the identification of key questions and approaches for the prevention of cystic fibrosis and other chronic lung diseases. Cystic fibrosis research guides the treatment of young children who have cystic fibrosis. The study found that inhaling concentrated saline—a treatment used in older children and adults—does not reduce how often infants and young children with cystic fibrosis need antibiotics for respiratory symptoms.
Visit Concentrated saline therapy not effective in young children with cystic fibrosis for more information. Antibiotic helps reduce risk of lung damage in children who have cystic fibrosis.
Visit Study: Azithromycin helps reduce risk of lung damage in children with cystic fibrosis and Pseudomonas infection for more information.
Cystic fibrosis makes airways more acidic, reduces killing of harmful bacterial. NHLBI-funded research has found that the surface liquid from normal airways in animal models is able to kill most bacteria very rapidly. However , cystic fibrosis makes airways more acidic, reducing the ability to kill bacteria. More research is needed to explore the clinical importance of this finding in people who have cystic fibrosis. Specific cell type associated with the CFTR gene.
Mice who do not have this specific cell type do not make the CFTR protein. This causes airway findings that are similar to those of cystic fibrosis. Advancing research for improved health. In support of our mission , we are committed to advancing cystic fibrosis research in part through the following ways: We perform research.
Our Division of Intramural Research , which includes investigators from the Pulmonary Branch , is actively engaged in the study of cystic fibrosis. We fund research. The research we fund today will help improve our future health. Our Division of Lung Diseases , which includes the Airway Biology and Disease Branch , supports research on the causes, diagnosis, prevention, and treatment of lung diseases including cystic fibrosis. We stimulate high-impact research.
Our Trans-Omics for Precision Medicine TOPMed Program now includes participants with cystic fibrosis, which may help us understand how genes contribute to differences in disease severity and how patients respond to treatment. The NHLBI Strategic Vision highlights ways we may support research over the next decade, including its objective to gain new insights in genes and pathways that influence the symptoms and severity of cystic fibrosis.
Gene editing for cystic fibrosis. NHLBI-funded researchers have made progress in treating cystic fibrosis by using a technique called gene editing. Gene editing makes changes to the DNA mutation in the cystic fibrosis gene to correct it. Development of safe and effective genome editing. Advances in genome editing made over the past decade now make it possible to precisely change the DNA code inside living cells. Visit NIH to launch genome editing research program for more information.
Genetic therapy for cystic fibrosis. Other research is studying how effective genetic therapy is in correcting the complications of cystic fibrosis. New genetic-based therapies may prevent or treat cystic fibrosis airways. Biomarkers and cystic fibrosis treatment development. We support research on biomarkers for cystic fibrosis drug development.
Biomarkers such as sweat chloride to evaluate CFTR function are already being used to diagnose cystic fibrosis, to monitor infections, for clinical trials, and to evaluate the effects of therapy. Treatment against bacterial infections in cystic fibrosis patients.
The bacterium P. Treatment to restore airway host defenses in cystic fibrosis. Highly acidic airways in cystic fibrosis cause changes in the mucus of the airways.
