  • Cystic fibrosis (CF), also known as mucoviscidosis, is a genetic disorder that affects mostly the lungs but also the pancreas, liver, kidneys and intestine.[1][2] Long-term issues include difficulty breathing and coughing up sputum as a result of frequent lung infections.
  • Other symptoms include sinus infections, poor growth, fatty stool, clubbing of the finger and toes, and infertility in males among others.
  • Different people may have different degrees of symptoms.
  • Occurance: 1 in 30,000 in US, 1 in 1,300 in Ireland
  • Primarily genetic, incureable
  • Congenitally unable to process Vitamin K very well - wonder if vitamin K injections would help
  • "While infants born with it 70 years ago would have been unlikely to live beyond their first year, infants today are likely to live well into adulthood"
  • "Many people with CF are on one or more antibiotics at all times, . . . "

Role of vitamin D on gut microbiota in cystic fibrosis - 2018

Journal of Steroid Biochemistry – Jan 2018 Pages 82-87
Mansi Kanhere, Benoit Chassaing, Andrew T. Gewirtz, Vin Tangpricha

  • Vitamin D plays a vital role in maintaining the integrity of the gut epithelium.
  • The mechanism underlying this association involves the reduction of pro-inflammatory cytokines such as IL-8 and inhibition of inflammation-induced apoptosis of intestinal epithelial cells by vitamin D.
  • Intestinal dysbiosis is prevalent in CF owing to multiple factors including malabsorption of nutrients and recurrent antibiotics.
  • VDR regulates the composition and functions of the gut microbiota and decreased expression of intestinal epithelial VDR disrupts microbial homeostasis.
  • Vitamin D could be a potential treatment option for altering dysbiosis in CF, but additional trials are needed to evaluate this.
