Cystic Fibrosis Affects The Human Body

Lungs – Mucus plugging, chronic bacterial infections, pronounced inflammatory response, damaged airways leading to respiratory insufficiency, progressive decline in pulmonary function.

Cystic fibrosis is an existence restricting autosomal recessive disorder that influences 70,000 people around the world. The condition is known to affect principally those of European descent, though cystic fibrosis has been accounted for in all races and ethnicities. [12] Unusually viscous emissions in the airway of the lungs and in ducts of the pancreas in people with cystic fibrosis cause hindrances that prompt aggravation, tissue harm and destruction of both organ systems. Studies show that Cystic Fibrosis is more prominent in White Americans than African Americans, and Hispanics. A large number of Americans are carriers of this mutated Cystic Fibrosis gene, however if an individual is affected they must acquire two of these genes keeping

In infants symptoms include coughing, wheezing, excess mucus in the lungs, shortness of breath, extremely salty skin and decelerated growth. With infants it is very common for them to develop pneumonia infections because of all the bacteria that resides in the lungs. With treatment, most patients with cystic fibrosis live into their 20’s and 30’s, some individuals with milder cases can live longer. Death is most often due to end-stage lung disease.Thus far no cure for the disease has been found. Although, research on gene therapy is promising. Treatment is generally aimed at alleviating symptoms, preventing infections, and slowing the progress of the disorder. (Egan’s 10th Ed,

Cystic Fibrosis causes abnormal amounts of excessively thick and sticky mucus to develop within the lungs, airways and the digestive system. Due to the thick and sticky mucus, digestive functions in the pancreas are impaired and bacteria is trapped in the lungs causing recurrent lung infections. Cystic Fibrosis Victoria (2015) states that symptoms of Cystic Fibrosis can include:

Cystic Fibrosis is a genetic disease which is progressive and limits breathing ability. The lungs and other organs are affected by a thick buildup of mucus. This mucus traps bacteria which leads lung damage, infections, and respiratory failure. The digestive enzymes being released is prevented, affecting the breakdown of food and nutrients being absorbed. ?More than 30,000 children and adults in the United States have Cystic Fibrosis. 70,000 people worldwide.? (Diagnosed With Cystic Fibrosis, Cystic Fibrosis Foundation) Someone who has Cystic Fibrosis have a defective gene from each parent which produces faulty protein. The CFTR gene is the gene that is mutated causing this. The channel that transports chloride in and out of cells is created by instructions that are created by CFTR gene. The regulation of chloride ions and water are prevented creating the thick mucus formed on the passageways of lungs, pancreas, and other organs. Cystic Fibrosis doesn?t cause learning problems are mobility of the person. Babies with this still develop and grow up normally. The average life expectancy is close to 40 years, and has been increasing in the last fifty years thanks to improved care. ?Chronic coughing, recurring chest colds, wheezing, shortness of breath, frequent sinus infections, and allergies that last all year, are the most common symptoms of Cystic Fibrosis.? (Cystic Fibrosis Symptoms) Since this disease is progressive

     Today, there is no cure for Cystic Fibrosis, but if the disease is found in an individual early enough, the patient can be recovered. About 85 to 90% of patients will have problems absorbing nutrients from their intestines. And because enzymes are lost when diagnosed, enzyme supplements are required to prevent bad nutrition and malnutrition. There are two main body parts that can be cared for the treatment of Cystic Fibrosis: The lungs and the chest. Lung problems can also be treated, but not cured. Antibiotics and other drugs may loosen the thick mucus in the lungs, but if it fails, a transplant lung may help to extend life. But about four hundred people die each year while waiting for a lung transplant. Also Chest physical therapy is a technique done by vigorous claps on the back and chest to loosen the thick mucus from the lungs. The average lifespan of an individual with CF is about thirty years.

Cystic Fibrosis cannot be developed or contracted it is something you’re born with. CF is a recessive disease, it occurs when a child inherits one defective copy of the gene from each parent. This gene mutation is responsible for cystic fibrosis. ("Cystic fibrosis Canada," 2011) This gene is known as the CFTR gene ("www.medincinet.com," 1996). Reference Figure 3. The “gene makes a protein that controls the movement of salt and water in and out of your body's cells. In people who have cystic fibrosis, the gene makes a protein that doesn't work right. This causes the thick, sticky mucus” ("www.medincinet.com," 1996).

While the buildup of mucus on the lungs doesn’t allow the person to breathe as well, the buildup of mucus in the pancreas doesn’t allow the release of digestive enzymes that help the body break down food and absorb nutrients. There are many symptoms that come along with Cystic Fibrosis. The main symptom of Cystic Fibrosis is wheezing and shortness of breaths along with always having some type of lung infection

Cystic fibrosis is a disorder that causes severe damage to the respiratory and digestive system. (Saint Francis Medical Center) It is caused by an inherited defective gene from both parents, specifically the CFTR gene, which causes the cells to overproduce mucus, digestive juices, and sweat. Normally, the fluids that are secreted are slippery and thin. However, with cystic fibrosis, the defect in the gene causes thick and sticky secretions. Instead of the secretions having lubricant properties, it clogs up tubes, passageways, and ducts, especially in the pancreas and lungs.

Cystic fibrosis is an autosomal recessive disorder due to a defect in the cystic fibrosis transmembrane receptor, protein buildup causing thick mucus and secretions in lungs, pancreas, liver & intestines. The clinical manifestations include respiratory with recurrent lung infections (S. aureus, Pseudomonas), productive cough, dyspnea, chest pain, wheezing, the gastrointestinal with meconium ileus at birth, later failure to thrive, chronic diarrhea, systemic with infertility and heart exhaustion. Obstructive Lung disease, pancreatic insufficiency, elevated chloride in sweat diagnostic will lead to a bronchiectasis, infertility, growth delays and Meconium Ileus (MC initial presentation)

There are many incurable diseases in the world that affect an organism’s way of living. Cystic Fibrosis, a disease with no known cure, affects 1 out of 3600 Canadian child’s digestive system and lungs, while a person with sickle cell anemia is only expected to live forty to sixty years. Both of these diseases are similar in the way that they are inherited genetically; they are passed on from parents to their children. Scientists are producing a way to help these people called Genetic Engineering. This is a way of modifying an organism’s genome to produce a more desirable trait by manually adding new DNA.

Cystic Fibrosis mainly affects the lungs but can also affect various other organs like the pancreas, liver, kidneys and the intestine. It builds up mucus in your airway which leads to blocked biliary and pancreatic ducts and possibly a malfunctioning liver. It can also lead to the intestine not being able to absorb nutrients properly. In every person the airway excretes

In the respiratory system, the mucus causes breathing difficulties, frequent respiratory infections and eventually permanent lung damage. The mucus builds up providing bacteria with a place to flourish. The most common infection comes from a bacterium called Pseudomonas aeruginosa. The body's response to P. aeruginosa includes inflammation, which causes episodes of intense breathing problems (Pseudomonas Genome Project, 1998). Normally the body will get rid of excess mucus by coughing before it's a problem but with the thick mucus involved in CF the body has a harder time to get rid of the thicker mucus. Lung disease is the usual cause of death in most patients (National Institutes of Health, 1995). In the digestive system, mucus can block the supply of enzymes used to break down food. The result of the blockage of such enzymes is malnutrition. The patient will have an excessive appetite but will not experience any weight gain. What is also evident is a failure to grow, CF was often misdiagnosed vaguely as "failure to thrive" when physicians didn't know the reason for this poor growth. Sweating is also a problem in people with CF. One of the basic defects in CF is the faulty transport of sodium and chloride (salt). People with CF lose excessive amounts of salt when they sweat. This causes the natural balance of salt in the body to be off balance, which may cause abnormal heart rhythms (National Institutes of Health, 1995).

Cystic Fibrosis (CF) is an autosomal recessive gene that causes a wide range of symptoms because there are over 1,000 changes or mutations that can occur within the cystic fibrosis transmembrane receptor (CFTR) protein. The CFTR protein is generally a chloride ion chain “regulated by cyclic adenosine monophosphate and therefore can act as a regulator of other electrolyte channels”(Grossman, S., & Grossman, L. 2005, p. 46). Typically this protein allows chloride ions to exit mucus-producing cells allowing water to flow in and thin the mucus. However, if the CFTR protein has been mutated, such as in cystic fibrosis, chloride ions cannot exit. This causes the mucus to thicken, become sticky, and obstruct the various channels it passes through. This build up of mucus also prevents bacteria from being cleaned from cells thoroughly increasing the patients risk for infections (Grossman, S., & Grossman, L. 2005). However, the severity of CF depends on whether the patients have complete or partial loss of the CFTR gene. If the person has the classic form of CF abnormalities of CFTR will commonly affect “…the respiratory, gastrointestinal, endocrine and metabolic, and genitourinary systems”(Schram, C. 2012). However, if people have atypical forms of CF their genetic disorder may only affect one of the organ systems and may not be found until the patient develops symptoms in their late childhood, early adolescence, or adulthood

Cystic fibrosis is an inherited disease that ultimately leads to death. It affects every racial group worldwide, but its prevalence varies from country to country. In those with cystic fibrosis, the lungs and digestive system are primarily affected by the disease. With the new developments in treatment and management, the 50 percent survival rate from the 1970’s has greatly improved, allowing patients to continue to live their lives longer than ever expected in the past. The new developments in prevention of exacerbations, therapy drugs and methods to preserve lung function have done great things to help patients extend their lives. Education is another important aspect of treating cystic fibrosis. For example, more the
