Active clinical trials for "Fibrosis"

This study aims to evaluated nutritional status in patiets with cirrhosis

The Investigators propose to study pediatric subjects who are diagnosed with cystic fibrosis (CF) and patients with non-CF bronchiectasis, with the goal of developing markers of CF lung disease severity, progression, and therapy response. The Investigator's central hypothesis is that image-based markers can forecast pathophysiology prior to spirometric changes.

Cystic fibrosis related diabetes (CFRD) is associated with worse CF-relevant outcomes. The mechanisms underlying CFRD development are not fully understood, but recent evidence suggests Type 2 Diabetes Mellitus (T2DM) mechanisms may be involved and may involve incretins (gut secreted hormones that augment insulin secretion in response to a nutrient load). This study will examine the prevalence of Genome wide association study (GWAS)-implicated T2DM alleles (including TCF7L2) across the spectrum of glucose abnormalities in CF and will use this information to compare incretin and insulin secretion in non-diabetic children and adults with high risk and low risk alleles.

This study is designed for establishment of non-alcoholic fatty liver disease patients cohort to development of markers to predict histologic progression of liver fibrosis.

This study is designed to evaluate the genetics involved in the development of lung disease by surveying genes involved in the process of breathing and examining the genes in lung cells of patients with lung disease. The study will focus on defining the distribution of abnormal genes responsible for processes directly involved in different diseases affecting the lungs of patients and healthy volunteers. Optional CT Sub-study The standard CT scan will be compared to the low dose radiation CT scan for the 150 subjects enrolled in the sub-study to assess the variation between the two techniques. Specifically, the quantitative computer aided detection of lung CT abnormalities from LAM can be compared to assess whether low radiation dose CT exams is an alternative to conventional CT to monitor disease status. This optional sub-study will be offered to up to 100 adult subjects with lung disease and up to 50 children age 9 and older with CF. Children will not be enrolled in the optional CT sub-study unless they have had a standard CT scan for medical purposes to use in comparison. One additional low dose radiation CT scan of the chest may be done as part of this sub-study when these subjects have their next annual CT scan.

The principal aim of this study is to analyse L3-SMI (skeletal muscle index) in a cohort of patients with decompensated liver cirrhosis and TIPS (transjugular intrahepatic portosystemic shunt), and compare the prognostic power with TPMT (transverse psoas muscle thickness). Furthermore, the role of myosteatosis, determined in CT by L3-SMI, MRI and ultrasound will be studied.

This is a cross-sectional pilot study. The investigators seek to obtain early information pertaining to the relationship between measurements of myocardial perfusion reserve and myocardial fibrosis after receipt of Anthracycline-based chemotherapy (≥2 years prior).

Study Design and Methodology Study Population:Compensated Cirrhosis Study Design: An Ambi Prospective Cohort study Study Period: 2 Years Sample size: Retrospective- All patients from Jan 2010 to Mar 2017 Prospective- Assuming the incidence of clinical decompensation is 5%/year.With alpha of 5%, power 80% we need to enroll 138 cases. Further assuming 20% drop out 166 cases will be enrolled. Intervention: This is an observational study. No intervention will be given. Monitoring and assessment: All the routine investigation and clinical information will be collected at 6, 12,18 and 24 months.

Due to the hypobaric hypoxia during air travel, some patients with Cystic Fibrosis (CF) need supplemental oxygen during air travel. The study aims to evaluate if adding exercise desaturation to the pre-flight evaluation will help predict requirements for in-flight supplemental oxygen.

The objective of this study is to evaluate the predictive nature of the biomarker Porphyromonas catoniae measured at the age of 12 months in the occurrence of colonization with Pseudomonas aeruginosa at 36 months of age in children with cystic fibrosis.
