Cystic fibrosis (CF) treatment potential seen in improved gene therapy: Study

Cystic fibrosis (CF) treatment potential seen in improved gene therapy: StudyResearch has found cystic fibrosis (CF) treatment potential in improved gene therapy. Cystic fibrosis is a hereditary disease that causes the body to produce thick and sticky mucus, which can clog the lungs and obstruct the pancreas. An estimated 30,000 children are affected by cystic fibrosis within the U.S. and roughly 1,000 new cases are diagnosed each year.

Individuals with cystic fibrosis tend to have a shorter than normal life expectancy, but with medical advancements, many of them can live past the age of 40.


Cystic fibrosis primarily affects the lungs and digestive system and is caused by a defective gene. Researchers have found that improving gene therapy could offer hope in the treatment of cystic fibrosis.

Improved gene therapy shows promise for future cystic fibrosis

Cystic fibrosis is caused by mutations in the CFTR gene. Professor Zeger Debyser from the new study explained, “A few years ago, a new drug was launched that can repair dysfunctional chloride channels. Unfortunately, this medicine only works in a minority of CF patients. As for the impact of gene therapy, previous studies suggested that the treatment is safe, but largely ineffective for cystic fibrosis patients. However, as gene therapy has recently proven successful for disorders such as hemophilia and congenital blindness, we wanted to re-examine its potential for cystic fibrosis.”

The researchers decided to improve the current gene therapy based on inserting the genetic material for chloride channels into the genome of a recombinant AAV viral vector.

Dr. Debyser concluded, “We must not give CF patients false hope. Developing a treatment based on gene therapy will take years of work. For one thing, our study did not involve actual human beings, only mice and patient-derived cell cultures. Furthermore, we still have to examine how long the therapy works. Repeated doses might be necessary. But gene therapy clearly is a promising candidate for further research towards a cure for cystic fibrosis.”

Causes and symptoms of cystic fibrosis

Causes and symptoms of cystic fibrosisA defect in the gene CFTR leads to unusually thick and sticky mucus that is difficult to cough up out of the lungs. In the digestive tract this mucus impedes on normal pancreatic function, which inhibits food from being broken down and can lead to malnutrition.

If a person only has one of the defective genes, they are carriers of cystic fibrosis and although they don’t have it themselves, they have the potential to pass it on if their partner also has one of the defective genes. For a child to inherit cystic fibrosis both parents must posses the defective gene.

Signs and symptoms of cystic fibrosis include:

  • Salty tasting skin
  • Persistent coughing
  • Shortness of breath
  • Wheezing
  • Poor weight gain even with a large appetite
  • Greasy, bulky stools
  • Nasal polyps

Treatment of cystic fibrosis

Treatment of cystic fibrosisTreatment plans are geared towards the child’s specific needs and health problems. Respiratory and digestive therapy will most likely be ongoing forms of treatment as those two areas of the body are greatly affected by cystic fibrosis. Antibiotics are also required, along with regular check-ups, home treatment like postural drainage, and taking the necessary steps to prevent infection.

Respiratory therapy works to slow down lung damage and improve breathing. This form of treatment works to rid the body of excess mucus and keep the lungs healthy.

Digestive therapy involves the use of digestive enzymes to help assist absorption of nutrients in order to prevent malnutrition. Nutritional therapy is also used to replace any lost nutrients. Vitamins, high-calorie food, high-fat foods and drinking nutritional beverages are all ways to utilize nutritional therapy. Lastly, stool softeners may be used to help prevent stool blockages and constipation.

Home remedies for cystic fibrosis

Home remedies for cystic fibrosis involve the following:

  • Paying attention to nutritional and fluid intake – digestive enzymes may be necessary to break down nutrients. Doctors may recommend antacids, supplement high-calorie diet, special fat-soluble vitamins, extra fiber and extra salt.
  • Keep immunizations up-to-date to prevent infection; those with CF have a higher likelihood of developing complications related to illness.
  • Exercise to help loosen mucus.
  • Don’t smoke or be around smoke.
  • Maintain proper hygiene and wash your hands frequently.
  • Eat raw fruits and vegetables as they contain natural digestive enzymes.

It is recommended that you work closely with a doctor, so they can create at home treatment plans to help provide care and treatment if you have cystic fibrosis.

Mucus is your body’s first line of defense

Mucus has been found to be the first line of defense for the body. For example, it has been shown that licking a wound will actually help it heal faster because it signals white blood cells, which fight infection. The findings come from researchers at Lund University along with colleagues at Copenhagen and Odense in Denmark. Continue reading…


Mucus in stool normal or serious health concern?

There are many things that go into making up our stool, like water, bile, indigestible food and bacteria, but should mucus be found in stool as well? Mucus is a jelly which can be found in the body and intestines. Mucus is used in the body as lubrication and reduces damage caused by stomach acid. Our stool may contain small amounts of mucus as it gets picked up through the intestines. Continue reading…
