In cystic fibrosis (CF), ductal plugging and acinar loss result in rapid decline of exocrine pancreatic function. This destructive process results in remodeled islets, with only a modest reduction in insulin producing β cells. However, β-cell function is profoundly impaired, with decreased insulin release and abnormal glucose tolerance being present even in infants with CF. Ultimately, roughly half of CF subjects develop diabetes (termed CF-related diabetes, CFRD). Importantly, CFRD increases CF morbidity and mortality via worsening catabolism and pulmonary disease...

IMPORTANCE: Treatment recommendations for infants with CF standardize care, but most surveillance or treatment guidance of pulmonary manifestations are consensus-based due to sparse evidence. OBJECTIVE: To report observations about pulmonary correlates of growth and other clinical features in infants with CF. METHODS: We analyzed data from the prospective Baby Observational and Nutrition Study conducted in 28 centers across the US, including clinical features, medications, guardian diaries of respiratory symptoms, oropharyngeal swab cultures and chest radiographs (CXR) collected over the first year of life...

BACKGROUND: Nutritional therapy is one of the cornerstones in cystic fibrosis (CF) therapy. There is a strong association between nutritional status and pulmonary function and thus longevity. Therefore nutritional therapy should be continuously adapted to preserve or improve the nutritional status. This narrative review was written to reconsider nutritional therapy in CF based on the latest evidence available since the publication of the ESPEN - ESPGHAN - ECFS guidelines on nutrition care for infants, children and adults with CF...

BACKGROUND: CFTR mutations permitting residual function (RF) of the CFTR protein are disease-causing. These mutations are associated with a pneumopathy that is delayed in onset and is slower in progression than are more common forms of cystic fibrosis (CF), although the disease may become severe in some patients. RF mutations are among the most frequent in Italy, thus encouraging investigation of their prevalence and associated phenotypes. METHODS: Data from the Italian Registry were used to compare patients with at least one RF mutation with those homozygous for F508del...

BACKGROUND: Up to 10% of patients with Cystic Fibrosis develop cirrhotic CF-related liver disease with portal hypertension: CF cirrhosis (CFC). In a nationwide study, we aimed to determine the role of CFC on survival in the Netherlands between 1 and 1-2009 and1-1-2015. METHODS: We identified all CFC patients in the Netherlands, based on ultrasonographic liver nodularity and portal hypertension. A non-cirrhotic control group was obtained from the national Dutch CF patient registry...

BACKGROUND: Cystic fibrosis (CF) is an inherited condition causing disease most noticeably in the lungs, digestive tract and pancreas. People with CF often have malnutrition and growth delay. Adequate nutritional supplementation does not improve growth optimally and hence an anabolic agent, recombinant human growth hormone (rhGH), has been proposed as a potential intervention. This is an update of a previously published review. OBJECTIVES: To evaluate the effectiveness and safety of rhGH therapy in improving lung function, quality of life and clinical status of children and young adults with CF...

INTRODUCTION: Cystic fibrosis (CF) is a progressive, genetic disease that causes persistent lung infections and limits the ability to breathe over time. The combination of a cystic fibrosis transmembrane conductance regulator (CFTR) corrector and potentiator has provided a benefit by decreasing sweat chloride concentration in CF for the F508del-CFTR homozygous mutation, but it remains controversial in lung function, nutritional status, clinical score and safety. METHODS: The authors performed a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the efficacy and safety of combination therapy on lung function, nutritional status, clinical score and safety in CF for the F508del-CFTR homozygous mutation...

Cystic fibrosis (CF) is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Next to progressive airway disease, CF is also associated with intestinal inflammation and dysbiosis. Ivacaftor, a CFTR potentiator, has improved pulmonary and nutritional status but its effects on the intestinal microbiota and inflammation are unclear. Hence, we assessed the changes on the intestinal microbial communities (16S rRNA variable 3 gene region) and inflammatory markers (calprotectin and M2-pyruvate kinase [M2-PK]) in 16 CF individuals (8 children and 8 adults) before and after (median 6...

BACKGROUND: Cystic fibrosis (CF) is a disorder affecting the respiratory, digestive, reproductive systems and sweat glands. This lethal hereditary disease has known or suspected links to the dysbiosis gut microbiota. High-throughput meta-omics-based approaches may assist in unveiling this complex network of symbiosis modifications. OBJECTIVES: The aim of this study was to provide a predictive and functional model of the gut microbiota enterophenotype of pediatric patients affected by CF under clinical stability...

Pancreatic-insufficient children with cystic fibrosis (CF) receive age-group-specific vitamin D supplementation according to international CF nutritional guidelines. The potential advantageous immunomodulatory effect of serum 25-hydroxy vitamin D (25(OH)D) on pulmonary function (PF) is yet to be established and is complicated by CF-related vitamin D malabsorption. We aimed to assess whether current recommendations are optimal for preventing deficiencies and whether higher serum 25(OH)D levels have long-term beneficial effects on PF...
