Active clinical trials for "Fibrosis"

The study aims to determine if a popular dextrose candy alternative yields a similar glycemic curve compared to the standard oral Dextrose solution used in the Oral Glucose Tolerance Test.

In patient with liver cirrhosis ,thyroid functions are largely affected in our study we studied the changes in thyroid functions in patients with liver cirrhosis

Hepatitis C Virus (HCV) infection is among the most common of all chronic liver diseases. HCV predominantly affects liver cells and causes the liver to become inflamed and damaged. This can lead to cirrhosis (scarring of the liver) and liver cancer leaving trial participants with need for liver transplant. The purpose of this study is to see how effective Glecaprevir/Pibrentasvir (GLE/PIB) is in a real world setting of participants with chronic HCV genotypes 1 to 6 and liver cirrhosis who have never received any treatment for HCV. GLE/PIB is a drug developed for the treatment of HCV infection. This is a prospective (future), observational study in treatment-naive (those who have not received treatment) participants with HCV genotypes 1 to 6 and compensated cirrhosis. All study participants will receive GLE/PIB as prescribed by their study doctor in accordance with approved local label. Pediatric (12 years and older) and adult participants with a diagnosis of HCV genotypes 1 to 6 and compensated cirrhosis will be enrolled in the study in Russian Federation. Participants will receive GLE/PIB tablets to be taken by mouth daily according to their physicians' prescription. The total duration of the study is 20 weeks, with a treatment period of 8 weeks and a follow up period of 12 weeks. There is expected to be no additional burden for participants in this trial. All study visits will occur during routine clinical practice and participants will be followed for 12 weeks.

Cystic fibrosis (CF) pulmonary disease is a major cause of morbidity and mortality in CF patients and is punctuated by episodes of acute exacerbation that require antibiotic treatment. Pseudomonas aeruginosa is the predominant bacterial pathogen isolated in patients with acute exacerbations, and practice guidelines recommend combination antibiotics directed against this pathogen as initial therapy. Such therapy traditionally consists of an antipseudomonal beta-lactam with either an antipseudomonal fluoroquinolone or an aminoglycoside. With growing P. aeruginosa multi-drug resistance, more adult patients present with isolates resistant to these traditional options. The polymyxins are a class of cyclic peptide antibiotics that exert bactericidal activity through binding to the lipopolysaccharide component of gram-negative bacterial membranes and include colistin and polymyxin B (PMB). In recent years, there is growing evidence of increased rates of acute kidney injury associated with colistin in critically ill patients. Additionally, population pharmacokinetic (PK) studies suggest that fixed drug dosing may yield an improved therapeutic index over the traditional weight-based dosing of this agent. Thus there is growing interest in use of PMB as an alternative in CF acute exacerbations but the optimal dosage regimen is not known. This is a single-center, open-label, non-interventional study to characterize the pharmacokinetics and safety of fixed-dose PMB in adult patients with CF by measuring serum concentrations in patients receiving IV therapy as a part of routine care. This study will help to validate existing population PK models and allow for adjustment of patient specific covariates (i.e. weight, renal function) unique to adult patients with CF. The study will also monitor for nephrotoxicity and neurotoxicity to determine if PMB has an acceptable margin of safety in this patient population. This investigation is the first to prospectively validate the pharmacokinetics and toxicities of fixed-dose PMB in CF and will guide optimal use of this compound in the management of acute pulmonary exacerbations.

Hemostasis-related disorders are common in cirrhosis and portal hypertension. However, it is not known whether the net effect of changes in hemostasis in the sense of predisposition to hemorrhagic or thrombotic state. It is suggested that increasing the concentration and activities of Von Willebrand factor (vWF) and decline ADAMTS-13 (A Disintegrin and Metalloproteinase with Trombospondin type 1 motif, member 13) may cause thrombophilic changes in cirrhosis and portal hypertension. The aim of this study was to investigate the changes in ADAMTS-13 (A disintegrin and metalloproteinase with thrombospondin motifs 13) and von willebrand factor (vWF) levels and activities in patients with cirrhosis and portal hypertension.

Heart failure with preserved ejection fraction (HFpEF) represents one of the largest unmet needs in cardiovascular medicine. Heart muscle scarring (myocardial fibrosis) is a key HFpEF disease mechanism and represents an important therapeutic target. Myocardial fibrosis can be measured non-invasively using the cardiovascular magnetic resonance imaging (MRI) extracellular volume (ECV) technique. However, some patients cannot undergo MRI scanning, and it is expensive. Circulating biomarkers in the blood that are sensitive to changes in myocardial fibrosis would represent an attractive cheaper and accessible alternative. This study aims to assess baseline levels of, and longitudinal change in, circulating biomarkers relating to fibrosis and cardiovascular disease in gifted samples from PIROUETTE trial participants, and evaluate the relationship between the biomarkers, anti-fibrotic treatment response and other study measurements.

The purpose of this study is to seeking a molecular signature of pathological radiation induced fibrosis based on the response of skin fibroblasts after irradiation, comparing two groups of patients distinguished by their individual radiosensitivity. The signature will integrate recent insights in terms of alternative splicing of mRNAs and level of expression of non-coding RNAs, particularly long non-coding RNAs, snRNAs, snoRNAs and microRNAs. In each group each expression patterns of candidate HSP proteins potentially predictive of pathological radiation induced fibrosis (HSP27, HSP70, αβ crystalline) in the serum and on cell culture will be characterized.

The objective of study is to prospectively determine if CPET with blood gas analysis should have a prognostic value in CF. The study plans to include 300 cystic fibrosis patients. Inclusion criteria will be: age >15 years, cystic fibrosis confirmed by chloride sweat test or genetic analysis, clinical and functional stability in the 2 month before CPET. Patients will perform a maximal exercise test on a cycloergometer during the inclusion visit, with pulmonary function testing and a six-minute walk test. The study will also include a visit every 6 months with: body mass index calculation, pulmonary function testing with DLCO (diffusing lung capacity for carbon monoxide), a six minute walk test, and antibacteriological study of sputum. The results of this study could help identify earlier the patients for referral to a lung transplantation centre, by using the usual criteria and the CPET abnormalities.

In this diagnostic study, the aim is at evaluating the diagnostic accuracy of MRI (Magnetic Resonance Imaging) to detect allergic broncho-pulmonary aspergillosis in patients with cystic fibrosis.

When developing new medications for lung diseases like Cystic Fibrosis (CF), scientists perform lab experiments using cells from the airways, physiology studies of how the lungs change when a drug is given, and clinical studies to determine how drugs affect overall health. The investigators of this study are seeking to develop computer models that will predict how patients will respond to drugs by just doing lab studies on cell samples from their noses. Such models would allow for medications to be developed more rapidly for all patients and allow treatments to be personalized as well. In order to develop these computer models a series of tests will be performed on patients who have CF. Tests will include sampling cells from the nose and measuring lung physiology using a combination of different imaging, breathing, and other studies performed both before and after participants take a therapy. Similar tests will be performed on people who do not have CF, and on the parents of the CF participants who carry a single CF gene because this will provide information on how specific genes might affect CF lung disease.
