Dietary intake and nutritional status in a Scandinavian adult cystic fibrosis-population compared with recommendations.

Background: Malnutrition is a well-known complication in cystic fibrosis (CF). There is good evidence that maintaining a normal body-weight correlates well with improved survival in CF. Energy intake in excess of 120% of the estimated average requirement (EAR) has been advised since 1980s.

Vitamin D deficiency as a risk factor for cystic fibrosis-related diabetes in the Scandinavian Cystic Fibrosis Nutritional Study.

Aims/hypothesis: Many cystic fibrosis patients are vitamin D-insufficient. Cystic fibrosis-related diabetes is a major complication of cystic fibrosis. The literature suggests that vitamin D might possess certain glucose-lowering properties.

Inverse relation between vitamin D and serum total immunoglobulin G in the Scandinavian Cystic Fibrosis Nutritional Study.

Background/objectives: The hallmark of cystic fibrosis (CF) is chronic lung inflammation. The severity of lung disease is closely correlated with immunoglobulin G (IgG) levels. Beyond its contribution to the bone health, the importance of vitamin D has not been fully recognized owing to the lack of human studies providing evidence of its benefit.

Co-morbidity of cystic fibrosis and celiac disease in Scandinavian cystic fibrosis patients.

Background: The co-morbidity of cystic fibrosis (CF) and celiac disease (CD) has been reported sporadically since the 1960s. To our knowledge, this is the first time a systematic screening is performed in a large cohort of CF patients.

Methods: Transglutaminase-IgA (TGA), endomysium-IgA (EMA) and total IgA in serum were measured in 790 CF patients (48% females, 86% with pancreatic insufficiency).

Anti-neutrophil cytoplasmatic antibodies and lung disease in cystic fibrosis.

Background: Bactericidal-permeability-increasing protein (BPI) is a potent anti-microbial protein produced by neutrophil granulocytes. Anti-neutrophil cytoplasmatic antibodies (ANCA) directed against BPI have been detected in up to 91% in patients with cystic fibrosis (CF). We aimed to evaluate the prevalence of BPI-ANCA in our CF patients and to determine whether presence of BPI-ANCA is correlated with organ damage.
