#Antioxidant #Carotenoids Inhibit the OxidativeStress that Causes #CysticFibrosis (#CF)

By Kyle J. Norton

Cystic fibrosis (CF) is the most common fatal genetic disease affecting mostly the lung in Canadian children and young adults, leading to difficulty breathing and coughing up mucus and frequent lung infections.

However, the condition has also been found in the pancreas, liver, kidneys, and intestine.
According to the Cystic Fibrosis Foundation Patient Registry, more than 30,000 people are living with cystic fibrosis in the US.

Believe it or not, most cases of CF are diagnosed by age 2.

The most common symptoms are depending on the location of cystic fibrosis including
sinus infections, poor growth, fatty stool, and clubbing of the fingers and toes.

In male adults, the condition also induces infertility as a result of the blockage or absence of the sperm canal.

Conventionally, as of today, there is no cure for CF. Most cases of CF caused by lung infection are treated intravenously, inhaled, or by mouth.

In severe cases, a lung transplant may be the only option.

Although most cases of CF are associated with a genetic preposition, environment, lifestyle, and age are also 2 main factors that increase the risk of CF.

Cystic Fibrosis Canada in the investigation of the risk of CF in older adults wrote, "Today, the estimated median age of survival of CF patients in Canada is over 50 years, and the majority of patients are over 18 years of age. CF patients enjoy an improved quality of life, pursuing careers, and starting their own families".

Lycopene is a phytochemical found in tomatoes in the class of carotenoids, a natural pigment with no vitamin A activity found abundantly in tomatoes and other red fruits and vegetables, such as red carrots, watermelons, and papayas,

Tomatoes provide about 80% of the lycopene in the world's diet. In plants, lycopene protects the host against excessive photodamage and performs various functions in photosynthesis.

In finding a potential compound for the treatment of lung disease researchers examined the effects of carotenoids, the potent antioxidants on singlet oxygen and other toxic oxygen species in patients with cystic fibrosis (CF).

The study included a total of 17 patients with cystic fibrosis (CF) and 10 normal children,

According to the assessment of plasma levels of four carotenoids, beta-carotene, alpha-carotene, lutein, and lycopene, levels of carotenoids in children with CF were significantly lower compared to regular control participants.

There was no significant difference in total cholesterol and total carotene between groups. Furthermore, there was no correlation between fat absorption or measures of adiposity in children with CF compared to control.

However, levels of selected carotenoids were correlated negatively with serum IgG levels associated with the measurement of inflammation.

More importantly, researchers also found that the differences in plasma carotenoid levels between children with CF and normal children were involved in the rapid turnover of carotenoids, by quenching of toxic oxygen species in inflammatory states of CF.


The results strongly suggested that improving the concentration of carotenoids that reduces the implication of the toxic ROS expression may have an impact on the prevention and treatment of CF.


Intake of lycopene in supplements should be taken with extreme care to prevent overdose acute liver toxicity.
