Active clinical trials for "Fibrosis"

A number of studies have described low exercise capacity and physical activity in patients with non-cystic fibrosis bronchiectasis (non-CF Bronchiectasis), although little research exists on using the cardiopulmonary exercise test (CPET) to evaluate exercise capacity and its most relevant changes after a pulmonary rehabilitation home-based program (PRHP). In addition, few studies have addressed tolerance to exercise and physical activity in severe cases of the disease. Aims: To evaluate the exercise capacity of non-CF BQ patients using CPET and physical activity after a pulmonary rehabilitation home-based program. Methodology: Our study describes a non-pharmacological clinical trial in non-CF BQ patients at the Virgen Macarena University Hospital (Seville, Spain). The patients were randomized into two groups: the control group (who were provided with training instructions) and the intervention group (who took part in a specific pulmonary rehabilitation home-based program).

The purpose of this study; The COVID-19 pandemic is to investigate the effects of COVID-19 fear levels of patients with cystic fibrosis on the psychosocial and quality of life levels of individuals.

The purpose of this trial is to evaluate if the use of a newly developed lipid formulation versus fish oil would better enable the absorption of essential fatty acids after 12 weeks of supplementation.

Analysis of exhaled breath condensate biomarkers and cough severity in patients with idiopathic pulmonary fibrosis.

This study measures the 4 metre gait speed (4MGS) test in patients with Idiopathic Pulmonary Fibrosis (IPF). The investigators are interested to see whether usual walking speed in IPF patients changes following pulmonary rehabilitation and if it changes, what is the smallest change that is meaningful to patients.

In the general population, age of puberty, and age of menarche in girls, are closely correlated with those of their mother. The severity of chronic disease has an impact on the stature, the weight gain and the onset of puberty: age of menarche is even later that chronic illness is serious. Cystic fibrosis is one of the major chronic diseases of children. Neonatal screening is organized since 2002, most girls with cystic fibrosis therefore currently have a very specialized and early care. Older patients were diagnosed during childhood. The optimization of the nutritional and respiratory management has allowed over the past two decades a significant improvement in the survival of these patients. Most young people reach adulthood, puberty and reproductive desire are a crucial issue in the care of these young adults. In literature, it is often noted an age of menarche delayed an average of 2 years compared to the general population, but correlated with the age of menstruation from the mothers. The factors involved in the conduct of cycles in the girl followed for cystic fibrosis are poorly known and there are few data on the characteristics of cycles. The menstrual irregularity and amenorrhoea episodes concern nearly half of women. On the pathophysiological level, studies in animals show that there is a direct effect of CFTR (Cystic Fibrosis Transmembrane Regulator) on the hypothalamic pituitary gonadal and reproductive capacity in mice. The literature data on the pubertal development, fertility and hormonal profile of these girls are for studies with low numbers and are very old. There is to date no French cohort study on this topic. The study is a multicenter cross-sectional descriptive study for pubertal and gynecological characteristics in girls followed annually in the reference centers Cystic Fibrosis two inter-region.

The prevalence of portal vein thrombosis (PVT) in patients with liver cirrhosis is 5-20%. Current evidence regarding the effect of portal vein thrombosis on the prognosis of cirrhotic patients remains under debate. Considering that PVT potentially elevates the portal pressure and thereby increase the risk of variceal bleeding, we focus on the patients with high-risk varices and variceal bleeding as the study population. Thus, the main goals are to analyze the effect of PVT on the incidence of first variceal bleeding in patients without any prior bleeding history but with high-risk varices, the incidence of recurrent variceal bleeding in patients with a history of variceal bleeding, and the treatment failure rate of variceal bleeding in patients with acute variceal bleeding. Certainly, the survival is also observed in all patients.

Reliable methods of evaluating liver fibrosis using noninvasive techniques in the pediatric population are limited and inconclusive. Liver biopsy remains the gold standard; however, it requires sedation in pediatric patients, has a risk of hemorrhage, and provides unreliable results secondary to sampling error. Sonoelastography is a new method of evaluating liver disease that eliminates these pitfalls. There are 3 types of quantitative sonoelastography currently in use. Transient elastography is a non-imaging based technique used in adults to measure liver fibrosis in which a mechanical vibrator creates a low-frequency wave causing shear stress in the liver at a fixed depth. This technique does not work in small livers and, therefore, is not appropriate for pediatric patients. Acoustic Radiation Force Impulse Imaging (ARFI) and Shear Wave Imaging (SWE) use real-time ultrasonography and administer focused high-intensity, short-duration pulses to produce shear waves in the liver tissue. ARFI calculates the degree of tissue displacement and creates an elastogram or measurement of the stiffness of the sampled liver tissue without corresponding images. It is limited since only a small sample or region of interest (ROI) can be obtained, and it is unable to provide a corresponding elasticity map of the tissue. SWE is the newest elastography technique. It measures tiny displacements of tissue in a larger ROI with corresponding ultrasound images which provides a side by side image of the liver and color-coded elasticity map of the sampled tissue. Advantages include a larger ROI and simultaneous viewing of the selected region of interest which provides better anatomic detail with a corresponding color map of the tissue elasticity which may result in more accurate scoring of the stage of fibrosis. There are a few studies of ARFI in the pediatric population. Studies using SWE for evaluation of liver fibrosis are also few, and, all but one in adults. However, these studies have shown it to be an accurate method for liver fibrosis staging. Use of SWE in assessing liver fibrosis in pediatric patients may represent an accurate noninvasive alternative to liver biopsy in evaluating liver fibrosis as well as avoid the use of sedation.

To describe the effectiveness of Kalydeco® treatment in patients with cystic fibrosis (CF) who have 1 of 8 non G551D gating CFTR mutations (G178R, S549N, S549R, G551S, G1244E, S1251N, S1255P, or G1349D).

This is a multicenter, prospective, two cohort, observational study over a 5-year period in Cystic Fibrosis (CF) patients with chronic Pseudomonas aeruginosa infection.The study will collect data over 1 year on respiratory function, antibacterial effectiveness, and clinical outcomes of treatment with inhaled antipseudomonal antibiotics and data over 5 years on microbiological and safety assessments.
