Filter by:Undernutrition is a common problem in patients with cystic fibrosis (CF) despite international consensus that the patients shall be given 120-200% of energy recommendations. Studies imply that one problem might be that the patients are not compensated for the essential fatty acid deficiency (linoleic acid, LA), which is well known in these patients. This deficiency is shown not to be due to fat malabsorption, but related to an increased turnover of arachidonic acid, a transformation product of LA. This abnormality is related to mutations associated with a more severe clinical phenotype. The most common and typical symptom of LA deficiency is poor growth. Studies in animals have further indicated that many of the symptoms in CF are related to the deficiency. A series of recent prospective studies from Wisconsin corroborate the importance of LA for growth. In Sweden LA has been supplemented to most patients since the late 70´, and the condition of patients have been among the leading in the world regarding growth, pulmonary function and survival. Short-term studies have shown better effect of LA supplementation compared to similar supply of energy without including extra LA. There are few long-term studies, performed before the gene was identified, giving very heterogeneous patient groups in regard to genotype, but with some positive results on growth and physiology. It´s of interest that modern personalized extremely expensive therapy with correctors and potentiators for Cystic Fibrosis Transmembrane Conductance Regulator may influence lipid metabolism. LA might thus tentatively be a cheap adjuvant to this modern therapy, but this has to be specially studied. The aim of the study is to find if there are differences in clinical and metabolic outcome between two groups, blindly given similar amount of extra calories, in one group consisting of linoleic acid.The benefit for the patients would be great if the expected positive effect can be proved in the planned study. The treatment will be cheap and without adverse effects. From socioeconomic point of view is would be a great advantage.
The current first-line treatment for HBV is long-term oral antiviral drugs to inhibit HBV DNA replication. First-line antiviral drugs recommended by the Chinese 2015 Hepatitis B Guidelines include ETV and TDF. This study is based on a real-world clinical cohort to retrospectively analyze the effects of ETV and TDF on the long-term (5-year) incidence of HCC in Chinese patients with chronic hepatitis B with compensated cirrhosis. The results will guide the revision of the Chinese HBV guidelines.
To prospectively study novel blood and lung biomarkers of disease activity in patients with IPF and other interstitial lung disease with the aims of prognostic modelling and disease clustering
Cystic fibrosis (CF) is the most common autosomal recessive inherited genetic disorder in North America, Australia and Europe. CF is due to cystic fibrosis transmembrane conductance regulator gene mutation (CFTR) coding for a chloride channel located at the apical membrane of epithelial cells. The most common mutation is the deletion of the amino acid phenylalanine at the codon 508 (ΔF508) affecting 70% of the patients. The CFTR channel participates in the regulation of the volume and composition of exocrine secretions. At the level of the lungs, this results in a thickening of the mucus with a dysfunction of the mucociliary clearance promoting colonization of pathogenic microorganisms. Patients with cystic fibrosis therefore have a natural susceptibility to develop acute and then chronic respiratory infections, gradually leading to irreversible respiratory tract lesions called bronchiectasis. Different germs such as Haemophilus influenzae and Staphylococcus aureus colonize the airways early in life. The progression of the disease causes furthermore a colonization by opportunistic germs such as Pseudomonas aeruginosa and Burkholderia cepacia, which are associated with higher mortality. Pulmonary exacerbation is a common complication of CF requiring administration of antibiotics. The choice of these antibiotics depends on the germs that the patient carries in his respiratory tract. The type of sampling and the conditions under which they are taken are therefore very important. Sputum and oropharyngeal smear are used in adolescents and children respectively to collect respiratory secretions in clinical routine. The recent literature describes induced sputum, obtained after a physiotherapy session and a hypertonic serum aerosol, as superior to the oropharyngeal smear alone and equivalent to bronchoalveolar lavage for the evaluation of the microbiological profile of patients who cannot expectorate. However, this technique takes time and requires the presence of a physiotherapist. Bronchoalveolar lavage is reserved for complex cases that do not respond to standard treatments. Finally, the nasal flora appears to be involved in the colonization of the lower respiratory tract. Sinuses are described as reservoirs of germs that can induce a recolonization of the lungs despite eradication of the germ (for example after a pulmonary transplantation) . To our knowledge, no study has investigated the involvement of nasal flora in the clinical course of children with CF.
Cystic fibrosis is the most common hereditary autosomal recessive disease in the Caucasian population. The diseases is caused by a mutation of the gene coding for the CFTR protein (Cystic fibrosis transmembrane conductance regulator), an ion channel present at the apical pole of the epithelial cells. The channel dysfunction induces a deficit in hydration and a hyperviscosity of different exocrine secretions. Clinically, Cystic fibrosis is a multi-systemic disease. Pulmonary and pancreatic involvement are classically in the foreground. Degradation of respiratory function, associated with acute and chronic infections, represents the major cause of morbidity and mortality. Pseudomonas aeruginosa is a ubiquitous gram-negative bacillus found primarily in stagnant water. Pseudomonas aeruginosa is capable of colonizing the digestive, pulmonary and urinary mucosa and the skin. This bacterium is incriminated in many opportunistic infections including respiratory infections in patients with cystic fibrosis. Pseudomonas aeruginosa infection is the most common parenchymal lung infection in the Cystic fibrosis community. Pseudomonas aeruginosa chronic carriage represents a factor of poor prognosis associated with an increase in morbidity and mortality. Complications related to chronic carriage of Pseudomonas aeruginosa justify the implementation of strategies of eviction, screening and eradication of acute Pseudomonas aeruginosa infection. In addition to Pseudomonas aeruginosa contamination of patients via the environment, hand and airborne infections between patients with Cystic fibrosis have been reported. Measures to eliminate cross-transmissions have therefore been implemented in a majority of hospitals. The aim of the study is firstly to identify the number of Pseudomonas aeruginosa cross-transmissions between patients with Cystic fibrosis followed-up in Cystic fibrosis center of HUDERF. Investigator will use the Pulsed-Field Gel Electrophoresis to assess the possibility of cross-infection. Depending on the results, Investigator will implement new strategies to avoid future cross-contamination in our different places of care (consultation, hospitalization, physiotherapy…).
Retrospective inclusion of lung cancers developed in a context of idiopathic pulmonary fibrosis, diagnosed and / or treated in participating centers. The cases are recovered retrospectively from the records of the pulmonology and pathology departments of our various partners.
Early diagnosis and treatment of liver fibrosis can repress or delay the development of cirrhosis and hepatocellular carcinoma. The purpose of this pilot study is to evaluate non-invasive multiparametric magnetic resonance imaging (MRI) techniques in the detection and grading of liver fibrosis, so that patients can be treated in time. These techniques combined could reach high diagnostic performance for detection of liver fibrosis, and could decrease the number of liver biopsies.
In collaboration with Dr.Birgit Alteheld, Institute of Nutrional Sciences of the university of Bonn, Germany the following effect is explored: Effect of a 4 week therapy with AZT on synthesis of lipoproteins as well as Docosahexaen and other fatty acids in patients with Cystic Fibrosis (CF). Moreover proinflammatory cytokines in blood and sputum are of interest.
The investigators conducted a randomized controlled trial to describe if multidisciplinary and patient-centered transitional care interventions for patients with cirrhosis post-TIPS can improve compliance behavior and reduce complications post-TIPS after discharge.
Examination the ability to early diagnose HCC by combining three biomarkers technology developed by WAKO, And their relevance to cirrhotic of patients with various backgrounds and the Israeli population. This blood test will serve as an additional diagnostic tool tools currently in use (Ultrasound and AFP levels) to cirrhotic patients with high risk to develop hepatocellular carcinoma. Another group that will be examined for all three biomarkers will be patients which already diagnosed with hepatocellular carcinoma, and have normal AFP level in order to examine the correlation between the presence of tumor, the number of them and the tumor size and the three biomarkers concentration in their blood
