What is cross-infection
During pregnancy, testing can be performed on the placenta chorionic villus sampling or the fluid around the fetus amniocentesis. However, chorionic villus sampling has a risk of fetal death of one in and amniocentesis of one in ;  a recent study has indicated this may be much lower, about one in 1, Economically, for carrier couples of cystic fibrosis, when comparing preimplantation genetic diagnosis PGD with natural conception NC followed by prenatal testing and abortion of affected pregnancies, PGD provides net economic benefits up to a maternal age around 40 years, after which NC, prenatal testing, and abortion have higher economic benefit.
While no cures for CF are known, several treatment methods are used. The management of CF has improved significantly over the past 70 years. While infants born with it 70 years ago would have been unlikely to live beyond their first year, infants today are likely to live well into adulthood. Recent advances in the treatment of cystic fibrosis have meant that individuals with cystic fibrosis can live a fuller life less encumbered by their condition.
The cornerstones of management are the proactive treatment of airway infection , and encouragement of good nutrition and an active lifestyle. At best, current treatments delay the decline in organ function. Because of the wide variation in disease symptoms, treatment typically occurs at specialist multidisciplinary centers and is tailored to the individual.
Targets for therapy are the lungs, gastrointestinal tract including pancreatic enzyme supplements , the reproductive organs including assisted reproductive technology , and psychological support. The most consistent aspect of therapy in CF is limiting and treating the lung damage caused by thick mucus and infection, with the goal of maintaining quality of life.
Intravenous , inhaled , and oral antibiotics are used to treat chronic and acute infections. Mechanical devices and inhalation medications are used to alter and clear the thickened mucus.
These therapies, while effective, can be extremely time-consuming. Many people with CF are on one or more antibiotics at all times, even when healthy, to prophylactically suppress infection.
This prolonged therapy often necessitates hospitalization and insertion of a more permanent IV such as a peripherally inserted central catheter or Port-a-Cath. Inhaled therapy with antibiotics such as tobramycin , colistin , and aztreonam is often given for months at a time to improve lung function by impeding the growth of colonized bacteria.
Antibiotics by mouth such as ciprofloxacin or azithromycin are given to help prevent infection or to control ongoing infection. Several mechanical techniques are used to dislodge sputum and encourage its expectoration. Chest physiotherapy is beneficial for short-term airway clearance. Other methods such as biphasic cuirass ventilation , and associated clearance mode available in such devices, integrate a cough assistance phase, as well as a vibration phase for dislodging secretions.
These are portable and adapted for home use. Ivacaftor is a medication taken by mouth for the treatment of CF due to a number of specific mutations. Aerosolized medications that help loosen secretions include dornase alfa and hypertonic saline.
As lung disease worsens, mechanical breathing support may become necessary. Individuals with CF may need to wear special masks at night to help push air into their lungs. These machines, known as bilevel positive airway pressure BiPAP ventilators, help prevent low blood oxygen levels during sleep.
Non-invasive ventilators may be used during physical therapy to improve sputum clearance. Some lung infections require surgical removal of the infected part of the lung. If this is necessary many times, lung function is severely reduced. The most effective treatment options for people with CF who have spontaneous or recurrent pneumothoraces is not clear. Lung transplantation often becomes necessary for individuals with CF as lung function and exercise tolerance decline. Although single lung transplantation is possible in other diseases, individuals with CF must have both lungs replaced because the remaining lung might contain bacteria that could infect the transplanted lung.
Newborns with intestinal obstruction typically require surgery, whereas adults with distal intestinal obstruction syndrome typically do not.
Treatment of pancreatic insufficiency by replacement of missing digestive enzymes allows the duodenum to properly absorb nutrients and vitamins that would otherwise be lost in the feces.
However, the best dosage and form of pancreatic enzyme replacement is unclear, as are the risks and long-term effectiveness of this treatment. So far, no large-scale research involving the incidence of atherosclerosis and coronary heart disease in adults with cystic fibrosis has been conducted. This is likely because the vast majority of people with cystic fibrosis do not live long enough to develop clinically significant atherosclerosis or coronary heart disease.
Diabetes is the most common nonpulmonary complication of CF. It mixes features of type 1 and type 2 diabetes, and is recognized as a distinct entity, cystic fibrosis-related diabetes. There is no strong evidence that people with cystic fibrosis can prevent osteoporosis by increasing their intake of vitamin D. Poor growth may be avoided by insertion of a feeding tube for increasing food energy through supplemental feeds or by administration of injected growth hormone.
Sinus infections are treated by prolonged courses of antibiotics. Sinus surgery is often used to alleviate nasal obstruction and to limit further infections.
Nasal steroids such as fluticasone are used to decrease nasal inflammation. Female infertility may be overcome by assisted reproduction technology, particularly embryo transfer techniques. Male infertility caused by absence of the vas deferens may be overcome with testicular sperm extraction , collecting sperm cells directly from the testicles. If the collected sample contains too few sperm cells to likely have a spontaneous fertilization, intracytoplasmic sperm injection can be performed.
Whether taking antioxidants affects outcomes is unclear. The prognosis for cystic fibrosis has improved due to earlier diagnosis through screening and better treatment and access to health care. In , the median age of survival of children with CF in the United States was six months.
Chronic illnesses can be very difficult to manage. CF is a chronic illness that affects the "digestive and respiratory tracts resulting in generalized malnutrition and chronic respiratory infections". According to Schmitz and Goldbeck , CF significantly increases emotional stress on both the individual and the family, "and the necessary time-consuming daily treatment routine may have further negative effects on quality of life".
Exercise is promoted to increase lung function. Cystic fibrosis is the most common life-limiting autosomal recessive disease among people of European heritage. In Canada, about 4, people have CF. Although technically a rare disease, CF is ranked as one of the most widespread life-shortening genetic diseases.
It is most common among nations in the Western world. An exception is Finland , where only one in 80 people carries a CF mutation. In contrast, only one in 15, African American children suffered from it, and in Asian Americans, the rate was even lower at one in 32, Cystic fibrosis is diagnosed in males and females equally. For reasons that remain unclear, data have shown that males tend to have a longer life expectancy than females,   but recent studies suggest this gender gap may no longer exist perhaps due to improvements in health care facilities,   while a recent study from Ireland identified a link between the female hormone estrogen and worse outcomes in CF.
The distribution of CF alleles varies among populations. CF is known to occur in only 20 families pedigrees in Finland. Other common autosomal recessive diseases such as sickle-cell anemia have been found to protect carriers from other diseases, an evolutionary trade-off known as heterozygote advantage.
Resistance to the following have all been proposed as possible sources of heterozygote advantage:. CF is supposed to have appeared about 3, BC because of migration of peoples, gene mutations, and new conditions in nourishment. In the 19th century, Carl von Rokitansky described a case of fetal death with meconium peritonitis , a complication of meconium ileus associated with CF.
Meconium ileus was first described in by Karl Landsteiner. She was the first to describe the characteristic cystic fibrosis of the pancreas and to correlate it with the lung and intestinal disease prominent in CF. The first linkage between CF and another marker Paroxonase was found in by Hans Eiberg , indicating that only one locus exists for CF.
Riordan on the seventh chromosome. Subsequent research has found over 1, different mutations that cause CF. Because mutations in the CFTR gene are typically small, classical genetics techniques had been unable to accurately pinpoint the mutated gene. Chromosome-walking and -jumping techniques were then used to identify and sequence the gene. CF represents a classic example of how a human genetic disorder was elucidated strictly by the process of forward genetics.
Gene therapy has been explored as a potential cure for CF. Results from clinical trials have shown limited success as of , and using gene therapy as routine therapy is not suggested. The focus of much CF gene therapy research is aimed at trying to place a normal copy of the CFTR gene into affected cells. Transferring the normal CFTR gene into the affected epithelium cells would result in the production of functional CFTR protein in all target cells, without adverse reactions or an inflammation response.
However, both methods were found to be relatively inefficient treatment options,  mainly because very few cells take up the vector and express the gene, so the treatment has little effect.
Additionally, problems have been noted in cDNA recombination, such that the gene introduced by the treatment is rendered unusable. A number of small molecules that aim at compensating various mutations of the CFTR gene are under development.
One approach is to develop drugs that get the ribosome to overcome the stop codon and synthesize a full-length CFTR protein. These drugs target nonsense mutations such as GX, which consists of the amino acid glycine in position being replaced by a stop codon. Aminoglycoside antibiotics interfere with protein synthesis and error-correction. In some cases, they can cause the cell to overcome a premature stop codon by inserting a random amino acid, thereby allowing expression of a full-length protein.
It is unclear as of if ursodeoxycholic acid is useful for those with cystic fibrosis-related liver disease. From Wikipedia, the free encyclopedia. List of people diagnosed with cystic fibrosis.

Acta Univ Carol Med. Normally, mucus is a slippery, watery substance. It keeps the linings of certain organs moist and prevents them from drying out or getting infected.
If you have CF, your mucus becomes thick and sticky. It builds up in your lungs and blocks your airways. Airways are tubes that carry air in and out of your lungs. The buildup of mucus makes it easy for bacteria to grow. This leads to repeated, serious lung infections. Over time, these infections can severely damage your lungs. The thick, sticky mucus also can block tubes, or ducts, in your pancreas an organ in your abdomen. These enzymes help break down food.
This can cause vitamin deficiency and malnutrition because nutrients pass through your body without being used. You also may have bulky stools, intestinal gas, a swollen belly from severe constipation, and pain or discomfort. CF also causes your sweat to become very salty.
Thus, when you sweat, you lose large amounts of salt. This can upset the balance of minerals in your blood and cause many health problems. Examples of these problems include dehydration a lack of fluid in your body , increased heart rate, fatigue tiredness , weakness, decreased blood pressure, heat stroke, and, rarely, death.
CF also causes infertility in men, and the disease can make it harder for women to get pregnant. The term "infertility" refers to the inability to have children. The symptoms and severity of CF vary. If you or your child has the disease, you may have serious lung and digestive problems. If the disease is mild, symptoms may not show up until the teen or adult years. The symptoms and severity of CF also vary over time. Other times, your symptoms may become more severe.
Lung function often starts to decline in early childhood in people who have CF. Over time, damage to the lungs can cause severe breathing problems. Respiratory failure is the most common cause of death in people who have CF. As treatments for CF continue to improve, so does life expectancy for those who have the disease. Today, some people who have CF are living into their forties or fifties, or longer.
Early treatment for CF can improve your quality of life and increase your lifespan. Treatments may include nutritional and respiratory therapies, medicines, exercise, and other treatments. Your doctor also may recommend pulmonary rehabilitation PR. PR is a broad program that helps improve the well-being of people who have chronic ongoing breathing problems. This causes thick, sticky mucus and very salty sweat. Research suggests that the CFTR protein also affects the body in other ways.
This may help explain other symptoms and complications of CF. More than a thousand known defects can affect the CFTR gene. The type of defect you or your child has may affect the severity of CF. Other genes also may play a role in the severity of the disease. Every person inherits two CFTR genes—one from each parent. However, they can pass the faulty CFTR gene to their children.
The image shows how CFTR genes are inherited. A person inherits two copies of the CFTR gene—one from each parent.
If each parent has a normal CFTR gene and a faulty CFTR gene, each child has a 25 percent chance of inheriting two normal genes; a 50 percent chance of inheriting one normal gene and one faulty gene; and a 25 percent chance of inheriting two faulty genes. Cystic fibrosis CF affects both males and females and people from all racial and ethnic groups.
However, the disease is most common among Caucasians of Northern European descent. The disease is less common among African Americans and Asian Americans.
More than 10 million Americans are carriers of a faulty CF gene. The signs and symptoms of cystic fibrosis CF vary from person to person and over time. Most of the other signs and symptoms of CF happen later. Figure A shows the organs that cystic fibrosis can affect. Figure B shows a cross-section of a normal airway. Figure C shows an airway with cystic fibrosis. The widened airway is blocked by thick, sticky mucus that contains blood and bacteria. People who have CF have thick, sticky mucus that builds up in their airways.
This buildup of mucus makes it easier for bacteria to grow and cause infections. An infection caused by these bacteria may be a sign of CF. People who have CF have frequent bouts of sinusitis si-nu-SI-tis , an infection of the sinuses. The sinuses are hollow air spaces around the eyes, nose, and forehead. Frequent bouts of bronchitis bron-KI-tis and pneumonia nu-MO-ne-ah also can occur.
These infections can cause long-term lung damage. Some people who have CF also develop nasal polyps growths in the nose that may require surgery. In CF, mucus can block tubes, or ducts, in your pancreas an organ in your abdomen. These blockages prevent enzymes from reaching your intestines.
This can cause ongoing diarrhea or bulky, foul-smelling, greasy stools. Intestinal blockages also may occur, especially in newborns. Too much gas or severe constipation in the intestines may cause stomach pain and discomfort. A hallmark of CF in children is poor weight gain and growth.
These children are unable to get enough nutrients from their food because of the lack of enzymes to help absorb fats and proteins. The vas deferens is a tube that delivers sperm from the testes to the penis. Women who have CF may have a hard time getting pregnant because of mucus blocking the cervix or other CF complications. CF causes your sweat to become very salty.
As a result, your body loses large amounts of salt when you sweat. This can cause dehydration a lack of fluid in your body , increased heart rate, fatigue tiredness , weakness, decreased blood pressure, heat stroke, and, rarely, death. CF also can cause clubbing and low bone density. Clubbing is the widening and rounding of the tips of your fingers and toes.
Low bone density also tends to occur late in CF. It can lead to bone-thinning disorders called osteoporosis and osteopenia. All States screen newborns for CF using a genetic test or a blood test. The genetic test shows whether a newborn has faulty CFTR genes.
If a genetic test or blood test suggests CF, a doctor will confirm the diagnosis using a sweat test. This test is the most useful test for diagnosing CF. A sweat test measures the amount of salt in sweat. For this test, the doctor triggers sweating on a small patch of skin on an arm or leg. He or she rubs the skin with a sweat-producing chemical and then uses an electrode to provide a mild electrical current.
This may cause a tingling or warm feeling. Sweat is collected on a pad or paper and then analyzed. The sweat test usually is done twice. High salt levels confirm a diagnosis of CF. In amniocentesis, your doctor inserts a hollow needle through your abdominal wall into your uterus.
He or she removes a small amount of fluid from the sac around the baby. In CVS, your doctor threads a thin tube through the vagina and cervix to the placenta. The doctor removes a tissue sample from the placenta using gentle suction. The sample is tested to see whether the baby has CF. CF carriers usually have no symptoms of CF and live normal lives. However, carriers can pass faulty CFTR genes on to their children. A genetics counselor can test a blood or saliva sample to find out whether you have a faulty CF gene.
This type of testing can detect faulty CF genes in 9 out of 10 cases. Cystic fibrosis CF has no cure. However, treatments have greatly improved in recent years. The goals of CF treatment include:. If you or your child has CF, you may be treated by a CF specialist.
This is a doctor who is familiar with the complex nature of CF. Often, a CF specialist works with a medical team of nurses, physical therapists, dietitians, and social workers. CF specialists often are located at major medical centers. These centers have teams of doctors, nurses, dietitians, respiratory therapists, physical therapists, and social workers who have special training related to CF care. Most CF Care Centers have pediatric and adult programs or clinics. The main treatments for lung problems in people who have CF are chest physical therapy CPT , exercise, and medicines.
Your doctor also may recommend a pulmonary rehabilitation PR program. CPT also is called chest clapping or percussion. It involves pounding your chest and back over and over with your hands or a device to loosen the mucus from your lungs so that you can cough it up.
You might sit down or lie on your stomach with your head down while you do CPT. Gravity and force help drain the mucus from your lungs. Some people find CPT hard or uncomfortable to do. Several devices have been developed that may help with CPT, such as:. Breathing techniques also may help dislodge mucus so you can cough it up. These techniques include forcing out a couple of short breaths or deeper breaths and then doing relaxed breathing. This may help loosen the mucus in your lungs and open your airways.
Aerobic exercise that makes you breathe harder can help loosen the mucus in your airways so you can cough it up. Exercise also helps improve your overall physical condition. However, CF causes your sweat to become very salty. Thus, your doctor may recommend a high-salt diet or salt supplements to maintain the balance of minerals in your blood.
If you exercise regularly, you may be able to cut back on your CPT. However, you should check with your doctor first. If you have CF, your doctor may prescribe antibiotics, anti-inflammatory medicines, bronchodilators, or medicines to help clear the mucus.
