Maintaining Respiratory Health in Cystic Fibrosis Patients
Cystic fibrosis (CF) is an inherited disease that primarily affects the lungs and the digestive system, however, it also affects a number of other organs and systems. More than 90% of mortality of CF patients is due to lung complications. Healthy lungs are important for a long life for people with CF, We will discuss two important topics for maintaining respiratory health. Chronic use of drug...
متن کاملRelationships between nasal potential difference and respiratory function in adults with cystic fibrosis.
This study investigated the relations between nasal transepithelial electric potential difference (PD) and the phenotype and genotype of cystic fibrosis (CF) adult patients. Basal nasal PD was measured in 95 adult CF patients who were classified into three groups of nasal PD (expressed as absolute values) according to the 10th and the 90th percentiles (28.3 and 49.2 mV, respectively), which def...
متن کاملNasal potential difference measurements in patients with atypical cystic fibrosis.
The diagnosis of cystic fibrosis (CF) is based on characteristic clinical and laboratory findings. However, a subgroup of patients present with an atypical phenotype that comprises partial CF phenotype, borderline sweat tests and one or even no common cystic fibrosis transmembrane conductance regulator (CFTR) mutations. The aim of this study was to evaluate the role of nasal potential differenc...
متن کاملNasal Potential Difference in Cystic Fibrosis considering Severe CFTR Mutations
The gold standard for diagnosing cystic fibrosis (CF) is a sweat chloride value above 60 mEq/L. However, this historical and important tool has limitations; other techniques should be studied, including the nasal potential difference (NPD) test. CFTR gene sequencing can identify CFTR mutations, but this method is time-consuming and too expensive to be used in all CF centers. The present study c...
متن کاملTransepithelial nasal potential difference (NPD) measurements in cystic fibrosis (CF).
The main underlying physiologic abnormality in cystic fibrosis (CF) is dysfunction of the CF transmembrane conductance regulator (CFTR), which results in abnormal transport of sodium and chloride across epithelial surfaces. CFTR function could be tested in vivo using measurements of nasal transepithelial potential difference (PD). Nasal measurements show characteristic features of CF epithelia,...
