Filter by:The investigators will conduct a single-center, prospective, randomized, placebo-controlled, double-blind pilot study of anti-herpesvirus therapy in patients with idiopathic pulmonary fibrosis (IPF). Patients with mild, moderate or severe IPF with serologic evidence of current or past Epstein-Barr Virus (EBV) or cytomegalovirus (CMV) infection. Randomization will be to pirfenidone plus placebo or pirfenidone plus valganciclovir. Thirty subjects will be enrolled and randomized to treatment with pirfenidone plus valganciclovir (20 subjects) or pirfenidone plus placebo (10 subjects) for 12 weeks. The primary outcome will be safety and tolerability will be determined by type, frequency and duration of adverse events (AEs) and serious adverse events (SAEs) after 12 weeks of study drug treatment. All study subjects will be offered bronchoscopy with bronchoalveolar lavage (BAL) at study initiation and upon completion of treatment (12 weeks). Subjects will then be followed up at routine clinic visits at 6, 9 and 12 months for data collection.
The strategy of neonatal screening for Cystic Fibrosis in France relies on Immuno Reactive Trypsinogen (IRT) at day 3/DNA analysis with a CF Elucigen 30 mutations kit/ IRT safety-net at day 21. This strategy has significantly improved the performance of CF neonatal screening (NNS) in terms of positive predictive value and sensitivity but revealed new difficulties. Up to 85-90% of CF patients detected through the NNS program has a classical CF form with a positive sweat test and 2, 1 or no CF causing mutations but the remainder has either 2 CFTR mutations with at least one non-CF causing mutation and a sweat test <60mmol/L or 1, 0 CFTR mutation and an intermediate sweat test value ≥ 30 et < 60mmol/L raising a diagnosis and prognosis dilemma. Meanwhile the vast majority of these cohorts will remain asymptomatic over time, some will develop symptoms prompting clinicians to maintain a rigorous surveillance for the entire atypical cohort, whose modalities vary a lot among centers and countries. This prospective multicenter study with a standardized assessment of a matched cohort with "atypical" CF versus "classical" CF from 6 years of age (60-65 cases in each cohort) is aimed at evaluating pulmonary and nutritional status to, better define the best monitoring follow-up, therapeutic management and familial genetic counseling.
This study is being done to test if it is safe to give stem cells to adult patients with Cystic Fibrosis (CF). The kind of stem cells we are studying are called allogeneic human mesenchymal stem cells or MSCs. MSCs are cells in the body that can grow into different types of cells and respond to various environmental situations. Allogeneic means the cells come from another person (a donor). This study is only looking at whether or not it is safe to give the stem cells to adults with CF and how the infusion is tolerated. In the future, other studies may be done to see if stem cells can be a new therapeutic treatment for CF. Stem cells, like other medical products that are intended to treat, cure or prevent disease, generally require approval from the U.S. Food and Drug Administration (FDA) before they can be marketed. The FDA has not approved any stem cell-based products for usual medical care, other than some specific blood forming stem cells for certain indications.
Patients with advanced cirrhosis have enteric dysbiosis with small bowel bacterial overgrowth and translocation of bacteria and their products across the gut epithelial barrier. This culminates in systemic inflammation and endotoxemia which induces innate immune dysfunction predisposing to infection and development of complications such as bleeding, sepsis and hepatic encephalopathy. It also plays a key role in the natural history of cirrhosis by influencing the rate of progression to advanced liver disease and terminal liver failure. The investigators propose an intervention utilising Faecal Microbiota Transplantation (FMT) from a healthy donor to modify the gut microbiome alleviating gut dysbiosis and immune dysfunction. This may ultimately reduce the progression to chronic liver failure and the development of infection and organ dysfunction. The primary objective of this study will be to assess whether stabilising gut dysbiosis with FMT in patients with advanced cirrhosis is both feasible and safe.

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.
Little is known about gynaecological follow-up and cervical screening in Cystic Fibrosis (CF). Only few studies have described contraceptive practices in cohorts of CF women. The investigators did a cross-sectional study in a cohort of 155 CF women attending the Lyon adult centre. Women attending the CF adult centre in 2014 completed a written questionnaire about their contraceptive choices, frequency of gynaecological follow-up and cervical screening. Other clinical data were collected from the CF adult centre registry. One hundred and twenty women (100%) answered the questionnaire, among whom two were post-menopausal (46 and 59 years of age), and five were pregnant. Seventy-four per cent of the women declared they had undergone gynaecological followup (89% of the women with transplantation), and only 55% reported having at least one previous Pap smear test. Among the transplanted patients, only 58% had had a Papsmear test, despite immunosuppressive treatment. The overall rate of contraception was only 64% and in diabetic women, it was 61%. Among contraception users; 65% used oral contraception, predominantly combined estrogen-progestagen (47%); among diabetic patients, 26% used progestin-only contraception. Intrauterine device accounted for 10% of patients using contraception, and tubal ligation only 4%. This study is limited by its cross-sectional design. Despite an internal validation of the questionnaire showing an almost perfect agreement, the risk of recall bias has to be taken into account. This study of practices highlights the importance of improved information regarding sexuality, fertility and reproductive health in young women with CF. A regular gynaecological follow-up and cervical screening is mandatory in this population. Better gynaecological care and contraceptive advice would help to avoid unplanned pregnancies, and optimize contraceptive selection in relationship to specific clinical conditions.
Respiratory Viral Infections (RVI) are particularly frequent in young children. Old data mention the deleterious role of some viruses such as the Respiratory Syncytial Virus in young children with cystic fibrosis (CF). However, recent epidemiological data on RVI in CF children are rare and the impact of most frequent viruses such as human rhinoviruses is usually not correctly evaluated. The aim of this study is to assess the frequency of lower and upper RVI during a 1 year follow-up in CF infants and to evaluate the impact of RVI at a clinical, microbiological and therapeutic level. Our hypothesis is that frequent and/or clinically severe RVIs have the worst impact in the short term and without any particular link with a specific virus as previously described.
PBC is a rare, autoimmune, cholestatic liver disease with genetic and environmental pathogenetic factors. Data about epidemiology of PBC in Switzerland are completely lacking. Epidemiology can be a powerful tool in yielding important clues as to burden and etiology of diseases. In addition, the investigators study will be the first one carried out in the country on PBC, and therefore will raise disease awareness and create a network.
This study is a randomized, double-blind, placebo-controlled trial in which eligible IPF subjects will be randomized to receive GBT440 or Placebo orally daily.
