Active clinical trials for "Fibrosis"

This protocol represents an open-label pilot study to assess whether oral administration of SBI in subjects with decompensated cirrhosis with ascites can lead improvements in the management of the disease. The impact of SBI therapy will be based on changes to markers of bacterial translocation, gut barrier damage, and inflammation as well as the impact on rates of SIBO. Study subjects will be given one packet of EnteraGam, each packet containing 5.0 g SBI, twice daily for 8 weeks.

There is evidence that an inpatient pulmonary rehabilitation of 3 weeks improves exercise capacity and quality of life in patients with idiopathic pulmonary fibrosis. However, there are no data available regarding long-term effects of this multimodal program. The aim of this study is to investigate the long-term impact of a rehabilitation program 3 month after finishing on exercise capacity and physical activity.

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.

The purpose of this study is to evaluate the effect of a nursing program in patients with cystic fibrosis.

Surgical resection is one of the curative treatment modalities for HCC. Limits are postoperative septic and liver functional complications related to an increase in bacterial translocation and systemic endotoxemia. Bacterial translocation is a passage of bacteria and bacterial degradation products from the intestine to the portal circulation. The endotoxemia secondary to bacterial translocation, stimulates endothelial production of nitric oxide (NO). NO is also a potent inducer of membrane instability, responsible for an increase in the permeability of the vascular endothelium and intestinal mucosa, possibly contributing to a worsening of bacterial translocation. Probiotics are live microorganisms which when administered in adequate amounts, provide a health benefit on the host ((Health and Nutritional Properties of Probiotics in Food Including Powder Milk with Live Lactic Acid Bacteria - Cordoba Argentina October 2001). Data from experimental and clinical literature show a significant effect of probiotics on the improvement of liver function and a decrease in infectious complications in patients with chronic liver disease. The proposed study would evaluate the effect preventive and therapeutic in a population of surgical patients, in whom the intestinal portal and hepatic inflammation promotes postoperative complications.

Unresectable, non-metastatic cirrhosis-related hepatocellular carcinoma (HCC) has a poor prognosis as there are no recommended curative treatments. Chemoembolisation is the most widely used treatment in these patients, but this technique can prove to be toxic. intrahepatic arterial chemotherapy with lipiodol and idarubicin could be an effective therapeutic approach, without deteriorating liver function. The rationale for this treatment can be resumed as follows: HCC are vascularised via the hepatic artery system The IHA perfusion of anthracyclines leads to high elimination via the liver with low systemic concentrations The absence of embolisation reduces toxicity the toxiciity profile of idarubicin is well known and the drug is widely used for the IV treatment of leukemia idarubicin is the most cytotoxic drug for tumor cell lines. The in vitro cytotoxicity of idarubicin is 100% at low concentrations Lipiodol can stay in contact with tumor tissue for several weeks after injection and act as a vector for the drug The idarubicin-lipiodol is more stable than lipidol emulsions usually given by intraarterial injection The emulsion is more stable with idarubicin than with other anticancer molecules Sequential inclusion in accordance with the "continual reassessment method" makes it possible to increase inclusions at a target toxicity level while reducing inclusions at doses that are too low or too toxic The aim of the treatment is to improve survival.

The study consists of 2 parts: Part A is a randomized, multiple-dose, double-blind, placebo-controlled sequential dose escalation study to evaluate GS-6624 in subjects with Idiopathic Pulmonary Fibrosis (IPF) and was completed in October 2011. Part B is a randomized, two-dose, open-label dose expansion study to evaluate GS-6624 in subjects with IPF and is currently enrolling.

The purpose of the study is to develop new biomarkers for studies of cystic fibrosis (CF). Defects in the gene encoding Cystic Fibrosis Transmembrane Regulator (CFTR) cause CF, an autosomal recessive disorder affecting mainly the pulmonary and digestive tract, leading to early death largely due to progressive loss of pulmonary function. In vitro experiments show that quercetin - a dietary supplement with a well-established safety profile for human use, including clinical trials in a variety of disorders encompassing cancer, heart disease, and as an anti-inflammatory agent - induces activation of CFTR. The nasal potential difference (NPD) test is a measurement of voltage across the nasal membrane and as a fundamental biomarker for CFTR activity in vivo. The NPD is a useful, well-established tool in CF research to determine both diagnoses as well as to measure the effect of new therapies. In vitro experiments show that quercetin induces activation of CFTR additive to that seen with current NPD reagents. In addition, it activates rescued mutant CFTR in vitro (∆F508 CFTR the most common cause of CF), whereas conventional agonists do not. Preliminary in vivo experiments mirrored these results and show that quercetin activates CFTR in human (n=12) NPD tests. Importantly, quercetin perfusion was well-tolerated by a validated sinus questionnaire and physician assessed nasal examination rating. These studies provide strong support for use of quercetin as potentiator of CFTR Cl- channel function by nasal administration. By adding quercetin to the sequence of perfusion solutions for NPD, the investigators may be better suited to detect ∆F508 CFTR activity of rescued mutant protein in the CF patient population.

The purpose of this research study is to test the pharmacokinetics, safety, and tolerability of an intravenous infusion of a drug called Ganite (gallium nitrate) in patients with cystic fibrosis. We want to see this drug is safe and tolerable and to see if high levels of the drug are found in the sputum.

The study investigates the effect of aminoacid infusion on proteinturnover in muscle from cirrhosis subjects, compared to healthy controls. The hypothesis is that aminoacid infusion can attenuate the increase in proteindegradation that follows cirrhosis.
