Cystic Fibrosis (earlier called also Mucoviscidosis) is a genetic disease which creates a dense mucus in all organs. This makes problems mainly in the lungs (because of tough unbeatable infections), in digestion (Pankreas), and in some other organs. The liver is a problem only in 10% of the patients, but Misha seems to have a quite tough version of CF (there are several thousand different mutations causing this illness). At the moment only symptomatic treatments are available (mainly strong Antibiotics, heavy physiotherapy and Enzyme, Vitamin etc. substitution), but genetic treatments are starting to be commercialized for some mutation types. The life expectancy has risen from less then 10 years in the ’80s, to 35.
