Research Paper On Cystic Fibrosis

Nearly 1 in every 30 Americans are a carrier of the recessive gene that leads to CF (About Cystic Fibrosis, n.d.). Although CF is a life-threatening condition, through the advancement of treatments and care, there has been a steady increase in life expectancy and improvement in the quality of life. The current mean age of survival is now 40. Although that does not seem very high, sixty years ago, a child diagnosed with CF did not survive childhood (About Cystic Fibrosis, n.d.). CF is a complex disease, where the types and severity of symptoms can differ widely from person to person. Symptoms may include fatigue, salty-tasting skin, persistent cough with phlegm, wheezing and shortness of breath, lung infections, and poor growth and weight loss (Cystic Fibrosis Symptoms, Causes & Risk Factors, 2018). Many different factors, such as the age of diagnosis, can affect an individual's health and the course of the

Cystic Fibrosis is an inherited recessive gene which means the disorder won’t affect anyone that’s a carrier. To obtain Cystic Fibrosis there are two ways, either, one parent is a carrier and the other has it (provided the parent with Cystic Fibrosis is female), or both parents are carriers. Parents can find out if they are carriers for Cystic Fibrosis with the use of genetic testing. When both parents are carriers for Cystic Fibrosis there a 25% chance the child will have Cystic Fibrosis, a 50% the child will be a carrier, and a 25% chance the child will not have Cystic Fibrosis nor be a carrier for it. In the United States there is about 30,000 reported cases of children and adults with Cystic Fibrosis, in the US there is an additional 1,000 cases reported each year, worldwide around 70,000 children and adults have Cystic Fibrosis. Cystic Fibrosis is the most common

     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).

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.

In this paper, I will talk about the symptoms, diagnosis, research, and how to live with Cystic Fibrosis. Cystic Fibrosis is a genetic disease of the secretory glands, which are the glands that make mucus and sweat, and mainly affects the lungs, pancreas, liver, intestines, sinuses, and sex organs.

Cystic Fibrosis (CF) is a disorder causing the body to release extremely thick and sticky mucus that clogs the lungs and pancreas, leading to problems with breathing and digestion, infection, and ultimately death. Abnormal secretion of sweat and saliva glands is also characteristic of CF. This disease a hereditary disorder of the exocrine glands that is characterized by respiratory and digestive problems and the most common inherited disease among Caucasians, affecting 3,600 live births in the Canada alone. CF affects men and women equally, but affects white people more than black people. This disease mainly affects children and young adults and is diagnosed by the age of three. Due to the advances in genetic research, diagnosis has been

Cystic Fibrosis is the most common genetically inherited disease in Australia with one out of every twenty-five people are carriers of the CF gene or similar gene mutations that end in a CF , symptoms of Cystic Fibrosis depend on the level of severity of the gene. Carriers will develop thick and sticky mucus within the lungs, airways, as a result carriers will experience a persistent and difficult cough, breathlessness, the inability to exercise, constant lung infections, inflamed nasal passage is the reason the life expectancy is 25 years of age. The CF gene also has a significant effect on the digestive symptoms such as foul smelling and greasy excretes with strain to excrete, intestinal blockage, the inability to gain weight and constipation.

Cystic Fibrosis, a very serious inherited genetic disease, is also known as CF and sixty-five roses. This disease affects one in every 3,000 live births. It may first appear in a newborn, but can appear all the way up until a young adult. However, ten percent of most cases are apparent at birth. CF affects the lungs and causes a build-up of abnormally thick mucus which leads to chest infections, and CF also affects the reproductive system. Doctors do not know what causes the mucus to thicken. CF’s infections usually lead to death in childhood and early adulthood. Most people infected with CF had a life span into their teens long ago. Now, due to advanced technology, the life span is in the fifties or older.

The mechanism of cystic fibrosis; simply put is the physical blockage of chloride ions as a result of a defective gene located in the long arm of chromosome 7 at region q31-q32 [figure 2.]. This gene is responsible the exocrine gland function involving multiple organ systems, primarily the respiratory system, gastrointestinal (GI) tract and reproductive system. With the faulty CFTR gene, the epithelial cells in the body cannot channel chloride ions across the membrane [figure 3.] and affecting the cells ability to properly regulate sodium and water, as they are closely related. The water is needed to produce a healthy, thin layer of mucus that protects against infection and keeps the membrane moist. This mucus builds up in the lungs, pancreas and liver mostly, creating harsh breathing conditions for the patient and a lack of digestive enzymes and bile for breaking down nutrients and in some cases lower than normal insulin

Cystic Fibrosis (Mucoviscidosis) is a disease that changes how the body produces sweat, and mucus glands. It causes organs such as the lungs to not function properly, and could be life threatening. Cystic Fibrosis is a genetic disease, and affects around 70,000 people worldwide. Every year a thousand new cases are reported.

The average life span of a person with Cystic Fibrosis is 25-30 years of age. Although the more traditional treatments of this disease are adequate, is there something else that could be even better? Gene therapy is fast becoming one of the more studied aspects of genetics today. Let's take a look at some details of Cystic Fibrosis and gene therapy.

     Cystic fibrosis is an inherited autosomal recessive disease that exerts its main effects on the digestive system and the lungs. This disease is the most common lethal genetic disorder in Caucasians, affecting one out of 2,500. On the bioethical front, CF was the first human genetic disease to be cloned by geneticists. The intent of this paper is to describe how the cystic fibrosis gene was identified, how the

Cystic fibrosis is found most commonly in individuals with European descent and very uncommon in African and Asian descent (O’Sullivan & Freedman, 2009). When cystic fibrosis was first documented in 1938, the life expectancy was only a few months for the patients (O’Sullivan & Freedman, 2009). Cystic fibrosis is still currently an incurable disease; however treatments have greatly improved over the past few decades. Years ago, individuals with cystic fibrosis would rarely live beyond his or her childhood, but now many individuals with the disease are living well into their adulthood (Falvo, 2014). The life expectancy over the past decade has increased tremendously. It

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
