Cystic Fibrosis

I have recently been diagnosed with Cystic Fibrosis. My genotype is DeltaF508 and D1152H. My mother lived with Cystic Fibrosis till she was 58 years old. She was quite a fighter. We never suspected that we kids had it. What I wonder, would my mother think of that? it turns out that my father did in fact have the CF mutation d1152h. This CF gene was discovered about 5 years ago. If it weren't for my sister doing her own research and having an issue with her lungs we still wouldn't know.

Interestingly, even though we thought we didn't have it, we actually had a greater chance of getting both defective genes because our mother had two bad genes and my fathers one bad gene (that we know of for sure). For all we know, he may have a mild form of it too. For my grandparents the chances were 25% for each child born that it might have CF. For us kids it was a 50% chance.

One of the interesting things about it is that if one were to guess which of us would be in worse shape you would think it would be me. I've abused my body much more than my sister however her lung problems seem to be worse than mine. Two things I think make all the difference for me. Using my bicycle most of my life rather than a car, my use of medicinal herbs and my focus upon diet which for a long time has been fairly healthy.

I use my bike as my main mode of transportation and I think of it that way. I have probably averaged more than ten miles per day since I was 15 years old.

I use an herb which acts as an expectorant. I cough while using this herb. The current political climate prevents me from being more specific but I believe that in the end we will find more than anecdotal evidence supporting the use of this herb for cystic fibrosis (already widely used in the United States for both recreational and medicinal use and quite legal in a number of states).

When I was young, I was diagnosed as having ADHD and put on ritalin. I very quickly dumped the ritalin in favor of the previously mentioned herb which worked much better. My mother, bless her heart, put me on a health food diet when I was 10 I think (and said i could smoke my funny herbs in my bedroom). I was allowed No food additives or dyes etc. Eventually I went vegetarian. I have been studying the relationship between food and health for a very long time. I believe it has made all the differnce.

So, to re-cap; Exercise to the point of being athletic (no joke!), Natural expectorant herbs to counter the tobacco, and excellent whole foods from the garden. The exercise that I've always gotten has given me an edge on survival and is the thing recommended by most doctors that treat CF patients. Get active! As active as you can!

What exactly is Cystic Fibrosis

Cystic fibrosis (also known as CF, mucovoidosis, or mucoviscidosis) is a genetic disorder known to be an inherited disease of the secretory glands, including the glands which makes mucus and sweat.

The main hallmarks of cystic fibrosis are salty tasting skin, appetite but poor growth and poor weight gain, excess mucus production, and coughing/shortness of breath. Males can be infertile due to the condition congenital bilateral absence of the vas deferens. Often, symptoms of CF appear in infancy and childhood. Meconium ileus is a typical finding in newborn babies with CF.

Although technically a rare disease, cystic fibrosis is ranked as one of the most widespread life-shortening genetic diseases. It is most common among nations in the Western world; one in twenty-two people of Mediterranean descent is a carrier of one gene for CF, making it the most common genetic disease in these populations.[citation needed] An exception is Finland, where only one in 80 people carry a CF mutation. In the United States, 1 in 4,000 children are born with CF. In 1997, about 1 in 3,300 caucasian children in the United States was born with cystic fibrosis. In contrast, only 1 in 15,000 African American children suffered from cystic fibrosis, and in Asian Americans the rate was even lower at 1 in 32,000.

Cystic Fibrosis is a monogenetic disease. Most genetic diseases involve more than one gene.

Theories about the prevalence of CF

The DeltaF508 mutation is estimated to be up to 52,000 years old. Numerous hypotheses have been advanced as to why such a lethal mutation has persisted and spread in the human population. Other common autosomal recessive diseases such as sickle-cell anemia have been found to protect carriers from other diseases, a concept known as heterozygote advantage. Resistance to the following have all been proposed as possible sources of heterozygote advantage:

  • Cholera: With the discovery that cholera toxin requires normal host CFTR proteins to function properly, it was hypothesized that carriers of mutant CFTR genes benefited from resistance to cholera and other causes of diarrhea. Further studies have not confirmed this hypothesis.
  • Typhoid: Normal CFTR proteins are also essential for the entry of Salmonella typhi into cells, suggesting that carriers of mutant CFTR genes might be resistant to typhoid fever. No in vivo study has yet confirmed this. In both cases, the low level of cystic fibrosis outside of Europe, in places where both cholera and typhoid fever are endemic, is not immediately explicable.
  • Diarrhea: It has also been hypothesized that the prevalence of CF in Europe might be connected with the development of cattle domestication. In this hypothesis, carriers of a single mutant CFTR chromosome had some protection from diarrhoea caused by lactose intolerance, prior to the appearance of the mutations that created lactose tolerance.
  • Tuberculosis: Poolman and Galvani from Yale University have added another possible explanation - that carriers of the gene have some resistance to TB.
