Filter by:The time on peritoneal dialysis may be limited for a significant number of patients that use this modality of renal replacement therapy due to the inability of the peritoneal membrane to clear solutes or achieve adequate ultrafiltration, termed peritoneal membrane failure (PMF). This can be devastating for patients who have become accustomed to the quality of life provided by peritoneal dialysis and who otherwise have done well on this therapy. There is clinical evidence suggesting that icodextrin preserves the peritoneal membrane transport characteristics which may be linked to reduced cumulative glucose exposure of the peritoneal mesothelial cells. Theories to explain the role of dextrose in PMF have focused for the most part on the high intracellular concentrations of glucose without consideration to the potential pathogenic role of the glucose transporters which allow glucose entry into the cell. Experimental evidence in non-mesothelial cell lines indicate that some cellular processes that occur under high glucose conditions may not be related to intracellular glucose metabolism but to the type of glucose transporter allowing glucose entry. 3,4 However, little is known about these glucose transporters in peritoneal mesothelial cells and their potential role in the development of PMF. We hypothesize the following - The presence of Sodium Glucose Co-transporter (SGLT1) on peritoneal mesothelial cells plays a role in PMF under hyperglycemic conditions. - Regulation of pro-fibrotic mediators such as reactive oxidative species,transforming growth factor β, and vascular endothelial growth factor are modulated by SGLT1 activation by glucose rather than glucose metabolism or concentration. - Icodextrin does not activate the SGLT1 transporter establishing a mechanism that may explain the beneficial effects of icodextrin on peritoneal membrane transport.
Due to the limitations and the invasive nature of liver biopsy, there has been extensive interest in developing non-invasive tests to measure liver fibrosis (1). These are alternatives to liver biopsy that can be used in clinical practice, with benefits in terms of cost, risk, and patient convenience (2). Clinically applicable non-invasive tests include radiological studies, transient elastography (TE), and serum markers. We aim at studying acceptability, reliability, applicability and practical aspects of invasive and noninvasive methods for assessment of hepatic fibrosis and cirrhosis among hepatologists.
This study is a single center, randomized pilot study to evaluate the clinical effectiveness of nasal high flow 20LPM humidification therapy in subjects with Cystic Fibrosis.
The purpose of this study is to determine whether a nutritional supplement is effective in the treatment of malnutrition in pediatric patients with failure to thrive or cystic fibrosis.
The objective of the investigators research program is to determine whether a combined exercise program (aerobic and resistance) improves abnormal glucose tolerance and diabetes control in CF patients. This program of exercises to increase strength and muscle endurance, exercise tolerance, will be assessed in a group of 12 CF patients with impaired glucose tolerance. The effect of exercise will be compared with a control group of 12 patients also glucose intolerant but do not participate in structured physical activity program. The duration of the exercise program will be 12 weeks and several measures (glucose tolerance, inflammatory profile, lung function, exercise capacity, muscle strength and endurance) will be conducted pre and post program to assess the program's impact .
Exacerbation in cystic fibrosis play an important role in terms of mortality and morbidity. Exacerbation frequencies is relatedto FEV1 decline and mortality. There is a relationship between exacerbation frequency and QoLdeterioration. Moreover exacerbation treatments present health costs burden leading to important physical psychological and social impact. Preventing exacerbation and early detection of these exacerbations may decrease intensity and freqauency of exacerbation leading to increase clinical status and QoLwith a decreased health cost. Patients actually follow in CRCM track exacerbations when visits out patient clinic and during phone call. If patients did not call or did not present regularly to out patient clinic, exacerbation detection came later and so increasde the burden and therapeutic pressure. The objective of our study is to identify earlier the potential exacerbations and so decreased the health costs and increased the patient's QoL. Forthis purpose we propose to use modern technologiessuch as smartphone in order to create alert when patients report weekly health satatus. We will compra patients randomize in control group with standart follow-up to patients randomize in the smartphone group.Moreover we will study the compliance and satisfactory degree of the use of this device in the interventional arm.
The purpose of this study is to determine whether TIPS combined with variceal embolization are effective in the prevention of variceal rebleeding in patients with liver cirrhosis.
The treatment burden for patients with cystic fibrosis (CF) is significant and poor adherence has been well-documented. The investigators hypothesize that a coaching intervention will empower young adults with CF to manage their lives with CF and improve health-related quality of life (HRQoL). The main aim of the study is to establish the feasibility and acceptability of a life-coaching intervention.
The goal of this research study is to better understand current treatment practices for pulmonary exacerbations (lung infections) and whether the Cystic Fibrosis National Patient Registry (CFFNPR)can be used for this type of study.
This study (ARD-3150-1202, ORBIT-4) will evaluate the safety and efficacy of inhaled Pulmaquin (ciprofloxacin dispersion for inhalation) compared to inhaled placebo in subjects who have a confirmed diagnosis of non-cystic fibrosis (non-CF) bronchiectasis with a history of pulmonary exacerbations and chronic P. aeruginosa infections.
