abstract        background and objectives: pseudomonas aeruginosa is the most frequent opportunistic pathogen isolated from the sputum of patients with cystic fibrosis (cf). resistance to β -lactam antibiotics may arise from over expression of the naturally occurring ampc cephalosporinases or acquired extended-spectrum β-lactamases (esbl). the aim of this study was to determine the antibiotic r...

Interleukin (IL)-8 levels are higher than normal in cystic fibrosis (CF) airways, causing neutrophil infiltration and non-resolving inflammation. Overexpression of microRNAs that target IL-8 expression in airway epithelial cells may represent a therapeutic strategy for cystic fibrosis. IL-8 protein and mRNA were measured in cystic fibrosis and non-cystic fibrosis bronchoalveolar lavage fluid an...

The effect of cystic fibrosis plasma on the net fluxes of 45Ca2+ and 35SO42- across the guinea-pig stomach and small intestine was investigated, using an automatic short-circuit current apparatus. A significant increase in net fluxes across the stomach and small intestine for 45Ca2+ in the presence of cystic fibrosis plasma compared with non-cystic fibrosis plasma was observed. There was an inc...

PURPOSE Acid neutralization during chemical clearance is significantly prolonged in children with cystic fibrosis, compared to symptomatic children without cystic fibrosis. The absence of available reference values impeded identification of abnormal findings within individual patients with and without cystic fibrosis. The present study aimed to test the hypothesis that significantly more childr...

OBJECTIVES To assess left ventricular systolic and diastolic function in adult patients with cystic fibrosis using radionuclide ventriculography. BACKGROUND Although myocardial fibrosis has been described in autopsy specimens of patients with cystic fibrosis, the possibility that myocardial dysfunction may occur during life in adult patients with cystic fibrosis has not been explored. METHO...

PURPOSE OF REVIEW Nutritional status in cystic fibrosis is important to the health and long-term survival of patients; however, children with cystic fibrosis are not achieving the dietary recommendations or achieving normal growth. This paper reviews current knowledge about behavioral and environmental barriers to dietary adherence in this population. RECENT FINDINGS Children with cystic fibr...

Background: Recent studies have shown that the course of cystic fibrosis in patients with this disease differs despite the same mutation in CFTR gene. We aimed to investigate the role of polymorphism in TNF α (-308) and TNF α (-863), and its effect on the phenotype of the patients with cystic fibrosis and progression of disease. Materials and Methods:...

Infection with Burkholderia cepacia due to social contact is well described in patients with cystic fibrosis. However, social transmission to non-cystic fibrosis individuals or chronic colonisation in non-cystic fibrosis individuals has not been described. A report of B cepacia bronchiectasis is presented where a previously healthy mother of two cystic fibrosis children colonised with B cepacia...
