Filter by:Cystic Fibrosis (CF) is a rare hereditary disease with autosomal recessive transmission, affecting 1 in 4700 births in France. Numerous studies have explored the links between oral health and CF, predominantly focusing on a children population. These studies reveal hyposalivation, a risk of dental erosion, an increased prevalence of enamel structural defects, but a reduced prevalence of dental caries in CF children, potentially explained by better oral hygiene. Periodontal disease does not appear to be increased in this population, while the oral quality of life of CF patients has been insufficiently studied. Today, emerging challenges arise due to the increased life expectancy of CF patients, attributed to the rise of modulators such as Kaftrio®, resulting in an adult-majority population in France. The study of periodontal diseases, associated with oral dysbiosis, becomes relevant as they represent bacterial reservoirs that could impact respiratory complications in CF patients. To deepen understanding of the links between oral health and CF, as well as to improve oral health of these patients, it is crucial to update the specific oral profile of this population. A cross-sectional survey using a questionnaire is proposed to include a large number of CF patients in France, aiming for real-life data. This questionnaire is constructed around internationally recognized tools for comparative analysis with normative data. Collaboration with the Patients Association "Vaincre la Mucoviscidose" (VLM) facilitates questionnaire creation, dissemination, and interpretation of results.
The goal of this clinical trial is to evaluate the efficacy of OsrHSA works to treat hypoalbuminemia in hepatic cirrhosis patients. It will also learn about the safety and immunogenicity of OsrHSA. The main question it aims to answer is whether OsrHSA is effective in elevating the serum albumin level of cirrhotic patients with hypoalbuminemia. Researchers will compare OsrHSA to the positive comparator, plasma-derived HSA (pHSA) to see if OsrHSA presents as non-inferior to pHSA in the indication of hypoalbuminemia in hepatic cirrhosis patients. Participants will be randomized in a 1:1 ratio to receive OsrHSA or HpHSA (20g IV qd) for up to 14 days, following an EOT visit. Follow-up visits will be taken on EOT+7d, EOT+14d, and EOT+30d, respectively.
The aim of this study is to evaluate the role of procalcitonin in bronchoalveolar lavage as a biomarker for assessment of severity of non-CF bronchiectasis in children in correlation with other markers (functional and radiological severity )
Despite the increasingly common use of cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies in treating cystic fibrosis (CF), it is still largely unknown whether or not other chronic therapies can be safely stopped. This SIMPLIFY sub-study is being done to test whether or not it is safe to stop taking dornase alfa (Dnase) in those people that are also taking elexacaftor/tezacaftor/ivacaftor (ETI). ETI is a combination CFTR modulator therapy that was approved by the Food and Drug Administration for people with CF who have at least one F508del mutation. The three drugs that make up ETI work together to allow many more chloride ions to move into and out of the cells, improving the balance of salt and water in the lungs. These changes result in better clearance of mucus from the lungs and improvements in lung function. Dornase alfa (Dnase) also improves clearance of mucus from the lungs to support lung function and has been available to people with CF for many years. Dnase is considered to be relatively burdensome and it is not known whether Dnase can improve or maintain lung function above what is already gained through ETI use. The goal of this SIMPLIFY sub-study is to get information about whether or not it is safe to stop Dnase by testing if there is a change in lung function in participants with cystic fibrosis (CF) who are assigned to stop taking Dnase as compared to those who are assigned to keep taking Dnase while continuing to take ETI. This is a sub study of master protocol SIMPLIFY-IP-19, NCT04378153. The sub study investigating the impact of discontinuing and continuing hypertonic saline is registered under NCTXXXXXXX (will add once available).
Despite the increasingly common use of cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies in treating cystic fibrosis (CF), it is still largely unknown whether or not other chronic therapies can be safely stopped. This SIMPLIFY sub-study is being done to test whether or not it is safe to stop taking inhaled hypertonic saline in those people that are also taking elexacaftor/tezacaftor/ivacaftor (ETI). ETI is a combination CFTR modulator therapy that was approved by the Food and Drug Administration for people with CF who have at least one F508del mutation.

These changes result in better clearance of mucus from the lungs and improvements in lung function. Inhaled hypertonic saline (HS) also improves clearance of mucus from the lungs to support lung function and has been available to people with CF for many years. HS is considered to be relatively burdensome and it is not known whether HS can improve or maintain lung function above what is already gained through ETI use. The goal of this SIMPLIFY sub-study is to get information about whether or not it is safe to stop hypertonic saline by testing if there is a change in lung function in participants with cystic fibrosis (CF) who are assigned to stop taking HS as compared to those who are assigned to keep taking HS while continuing to take ETI.

The goal of this study is to determine the extent to which excess dietary simple sugars serve as a secondary mediating factor in Cystic fibrosis-related diabetes (CFRD) development. The main questions it aims to answer are: - Whether conducting a randomized 2x2 factorial design that evaluates acute postprandial changes in glucose over 2 hours following ingestion of a mixed meal challenge that varies by glycemic index and consumption of a sugar-sweetened beverage is acceptable and feasible. - What are the preliminary changes in postprandial hyperglycemia, islet cell function, and incretin response to a high or low Glycemic Index mixed meal tolerance test (MMTT) with and without Sugar-Sweetened Beverages (SSB) in adolescents and young adults with CF Participants will be randomized to a mixed diet and blood will be drawn before and after the mixed meal challenge.
The impact of albumin administration in cirrhotics with acute variceal hemorrhage (AVH) is controversial. We aim to investigate the short-term rebleeding risk associated with albumin administration in a retrospective study of hospitalized cirrhotics with AVH with stable hemodynamics. This retrospective analysis includes clinical data of cirrhosis patients with acute variceal bleeding admitted to our hospital from January 2021 to October 2023. Propensity score matching will be performed to account for potential confounders associated with albumin use for outcome analysis. According to the outcome, patients will be divided into rebleeding group and non-rebleeding group. To investigate the impact of albumin infusion on the rebleeding risk in the propensity-matched cohort, patients will be divided into albumin user group and albumin non-user group. The primary outcome is the rebleeding risk within 30 days after discharge.
The goal of this observational cohort study is to learn about loss of muscle mass and muscle strength (sarcopenia) in patients with cirrhosis. The main question[s] it aims to answer are: - what is the prevalence and development of sarcopenia in cirrhosis? - what is the role of malnutrition? Participants will - undergo a muscle ultrasound of the lower and upper limb muscles - handgrip strength will be measured - malnutrition screening and assessment - complete a questionnaire to assess quality of life
Cirrhosis is a leading cause of morbidity and mortality world- wide and can develop on the basis of repetitive and/or chronic liver injury due to toxic, infectious, metabolic and genetic pathogenic factors. Traditionally, the natural history of cirrhosis has often been considered a one-way street, with a definite and irreversible progression from a compensated to a decompensated disease stage. But recent data has shown that if the underlying etiology can be successfully treated, cirrhosis can regress and recompensation of liver disease can occur. Hence, in this study we want to evaluate the incidence and predictive factors of recompensation in pediatric subjects with decompensated cirrhosis as per the Baveno VII criteria. We would also evaluate the predictive factors of recompensation in pediatric decompensated chronic liver disase (DCLD) subjects and would explore systemic and intestinal inflammatory markers as possible biomarkers for predicting recompensation in pediatric subjects with decompensated cirrhosis.
In our locality, limited studies have discussed AKI in patients with liver cirrhosis and its outcome, therefore we aim to highlight the incidence, patterns, risk factors, and outcomes of acute kidney injury in patients with liver cirrhosis at Sohag University Hospital.
