Filter by:Cystic fibrosis (CF) -- an autosomal recessive genetic disease affecting about 60,000 individuals worldwide, including about 3,800 in Italy -- is often associated with low bone mineral mass. The current aggressive therapies have ensured a much longer survival of CF patients but this has led to a higher frequency of osteoporosis and bone fractures, a serious problem which not only affects quality of life, but also hinders further therapeutic measures. The aim of this study, conducted on a large group of children, adolescents and young adults with CF, has been the evaluation of bone mass changes after 1 year of a simple treatment with RDA-adjusted dietary calcium plus 25-OH vitamin D supplementation, and the feasibility and efficacy of alendronate treatment (for another year) in patients not responding to calcium + 25-OH vitamin D alone.
The primary objective of the study was to evaluate the efficacy of lumacaftor in combination with ivacaftor at Week 24 in participants aged 12 years and older with cystic fibrosis (CF) who are homozygous for the F508del mutation on the CF transmembrane conductance regulator (CFTR) gene.

Cystic Fibrosis is a genetic disease with variable severity, and a predisposition for lung infection. Usually severity is determined by the class of CF mutations, but even among patients with the same severity of mutations there is a variation of the severity of CF. Haptoglobin has several types (phenotypes), one of them was found to be related to infectious complications. In this study the investigators aim to find a correlation between Haptoglobin phenotypes in patients with CF and frequency of infectious complications. To this end the investigators will collect serum from CF patients, and determine their Haptoglobin protein phenotype. The investigators will correlate Haptoglobin phenotype to retrospectively gathered data on infectious complications.
Cystic fibrosis (CF) is the most common autosomal recessive genetic disease in Caucasians. It results in lung disease that affects quality of life and causes early death. Lung damage from CF starts in infancy and continues over time. Lung damage can negatively affect how the lung functions. It would be ideal to measure lung damage in CF patients in three instances: (1) During the first year of life after diagnosis by state newborn screening programs, (2) In children and adults over long periods of time (years), and (3) During times of illness (pulmonary exacerbation), to allow for better treatment and therapy to prevent loss of lung function. The lung is made of elastin, collagen and cartilage. When the lung is damaged by CF, these components break down into pieces that can be measured in urine, sputum and blood. These products may represent markers of lung injury. We believe that the levels of these markers will be increased over time in CF patients and even higher in patients who are sick with lung symptoms. The goal of my research is to measure the amount of lung breakdown products in urine, sputum and blood in infants, children and adults with CF during times when well and also during times of illness. I also hope to use new technologies involving the study of proteins and metabolites in samples like sputum, urine and blood to help provide new information regarding CF lung disease. These studies will help us to better treat CF lung disease.
Shortness of breath (dyspnea) during exercise is a major source of distress and is a commonly reported symptom in patients with cystic fibrosis (CF). Due to the investigators' poor understanding of how dyspnea develops, there are no treatments that consistently reduce dyspnea in this population. The investigators aim to acquire a more comprehensive understanding of the physiological mechanisms of exertional dyspnea in CF patients. This study will likely identify an important physiological mechanism of dyspnea in CF and may contribute to the development and use of effective treatments to reduce dyspnea in this population. The central hypothesis is that the impaired tidal volume (VT) response during exercise in CF, in the setting of increased ventilatory demand will give rise to different qualitative descriptions of exertional dyspnea compared with healthy age and sex-matched controls. Specifically, CF patients will select "increased work and effort" as their dominant descriptor of dyspnea up to the VT inflection/plateau. Beyond this point, CF patient's dominant descriptor will become "unsatisfied inspiration." In contrast, healthy control participants will report "increased work and effort" throughout all phases of exercise and will not report "unsatisfied inspiration", even after the VT inflection/plateau.
Patients with cystic fibrosis are at risk of developing low bone mineral density (BMD) potentially leading to pathological fractures at adult age. Recent data from our center and others have suggested that low BMD could be observed very early in life. However, quantitative bone abnormalities found out by Dual X-ray absorptiometry (DXA) need to be confronted to qualitative evaluation of bone microarchitecture (surrogate of bone strength). High-Resolution peripheral quantitative computed tomography (HR-pQCT) is a recent technology with very high spatial resolution. Images obtained with this technic are considered as virtual bone biopsies. It enables an accurate bones' cortical and trabecular surfaces exploration in a three-dimensional manner, and therefore provides informations on bone microarchitecture as well as bone density. The aim of this study is to evaluate bone microarchitecture of paediatric patients matched to sex-age-pubertal status-healthy volunteers. In the meantime, biological markers will be collected and DXA (Dual-energy x-ray absorptiometry) will be performed in order to explore potential correlations HR-pQCT parameters.
This is a study of the short-term effects of ivacaftor on sweat chloride concentration and lung function in cystic fibrosis (CF) patients who fall outside current FDA approval. This new, first of its kind drug is approved for use only in CF patients with the G551D mutation in whom it safely confers considerable benefits. However, it is highly likely that CF patients with many other mutations can benefit similarly from this drug, some of whom can be identified by phenotype or genotype. We will enroll up to 30 CF subjects with clinical presentations in which there is one or more signs of residual CF channel function. The signs of residual function include: normal digestion, concentration of chloride in sweat between 55 and 85, or milder than expected CF disease in a CF patient with severe gene mutations. The primary outcome measure will be the difference in sweat chloride concentration measured in subjects on placebo and on ivacaftor. Secondary outcome measured will be lung function.
Cystic Fibrosis (CF) is a congenital disease secondary to the abnormal function of CFTR. Patients with CF have an alteration of essential fatty acids, Arachidonic Acid (AA) is increased and Docosahexanoic Acid (DHA) is decrease and the ratio ω-6/ ω-3 is elevated, all these alterations stimulated a chronic and bad regulated state of inflammation. For this porpoise, a fase IV trial, multicentric, controlled, double blind, placebo and parallel in patients elder than two months old and randomized to received every day a dietetically supplement with DHA or placebo, will be done during 12 months. The trial has as a principal objective to proved if this long term supplementation could decrease in contrast with placebo.
Perhaps one of the most disturbing aspects of Cystic Fibrosis (CF) is the associated premature death. Oxidative stress has been observed in patients with CF and exercise intolerance has been shown to predict mortality in patients with CF, regardless of how healthy their lungs are. A critical barrier to improving the quality of life and longevity in patients with CF is our lack of knowledge regarding the different reasons why patients with CF cannot exercise to the level of their peers. We have collected preliminary data to support our central hypothesis that oxidative stress contributes to the impairment in blood vessel function at rest and during exercise which ultimately oxygen transport and delivery resulting in exercise intolerance. Exercise is therapeutic medicine for patients with CF and this investigation represents a major breakthrough in the approach to begin understanding the physiological mechanisms which contribute to exercise intolerance in these patients.
