Filter by:A research team member will brush the inferior surface of the subjects' middle turbinate (nasal cavity) using a cytology brush to obtain the cells needed to perform our functional respiratory assays. An individual trained in phlebotomy will draw one 3 ml lavender top tube of blood to test c-reactive protein, calprotectin, and lactoferrin. They will also draw a 5 ml gold top serum separator tube of blood to test fibroblast growth factor-19. The participant will answer questions from the baseline survey and report their current medications interview-style with the research team member.
The overarching hypothesis is that CF carriers are at increased risk for developing most of the extrapulmonary conditions associated with CF compared to the general population. Specifically, it is hypothesized that this pilot data will detect subclinical evidence of pancreatic and kidney disorders among CF carriers. This will be determined by bringing CF carriers and controls to the CRU for one visit where they will answer survey questions and undergo laboratory testing. Additionally, they will collect urine and stool samples at home that will be sent to outside laboratories for testing.
The working hypothesis is that in patients who are rectal carriers of MDR-GNB (Multi drug-resistant gram negative bacilli), the rate and speed of eradication of the carrier status obtained with NAA regimens are insufficient and could be improved with additional interventions directed to restore a healthy fecal microbiota or to increase the colonization resistance by the putative beneficial activity of lactate-producing bacteria and bifidobacteria. A healthier colonic microbiota environment is expected not only to promote the eradication of the existing MDR organisms but also to hinder the subsequent recolonization and hopefully the risk of infection with gut dysbiosis -associated pathogens (MDR-GNB, C. difficile and Candida). The principal objective of the study is To compare the decolonization efficacy at the end of the study (60 ± 7 days after randomization) of the administration of a probiotic ("Vivomixx®" 2 sachets/12h for 2 weeks) versus the administration of two doses (administered a week apart) of a fecal microbiota transplantation preparation (equivalent to 50 g of healthy donor feces) and no treatment (control arm) in patients with rectal colonization with MDRGNB (ESBL-producing Klebsiella pneumoniae, CPE and MDR/XDR (multi drug-resistant/ extensively drug-resistant Pseudomonas aeruginosa).
