“Woe to that child which when kissed on the forehead tastes salty. He is bewitched and soon must die.” This European adage accurately describes the fate of an individual diagnosed with cystic fibrosis during ancient times.1
Cystic fibrosis (CF) is a disease state resulting from a dysfunction in the cystic fibrosis transmembrane receptor (CFTR). It is the most common life-limiting disorder in the white population, with an incidence of 1 in 2,000 to 4,000 live births and a prevalence of 30,000 affected individuals in the United States.2–7
Currently with care, affected individuals have an expected life span of 36 years. Multiple organ systems are affected in CF individuals; especially, the lungs, the digestive system, and the reproductive organs. Mortality is most commonly due to chronic organ damage or resistant pulmonary infections.8
The pharmacist plays an essential role in the development and management of a pharmacotherapeutic care plan for the CF patient.
CF is an autosomal recessive disease occurring in approximately 1 in 3,500 newborns. In the 1970s, patients only survived into their teen years. By 2006, progress in care had extended survival to 36 years. Institution of care at a young age impacts long-term survival; hence, timing of diagnosis and recognition of signs and symptoms is crucial.2–...
