NCT02727959
The IBSEN III study will investigate the incidence of inflammatory bowel disease in South Eastern Norway and describe the clinical course of the disease. The investigators will map newly diagnosed and treatment naive IBD patients at various levels (epidemiological, clinical, psychosocial and nutritional as well as immunological, genetic, epigenetic and microbial) as a basis to improve targeted and individualized treatment and care. The investigators will include incident IBD patients at all local- and university hospitals in the South Eastern Health Region in 2016-2018 and follow-up prospectively for five years. The investigators will use standardized and validated registration methods allowing comparability with previous national and international IBD cohorts, link data to national health registries and collect blood, feces and biopsies for bio banking.
NCT03548480
The gut microbiome has recently emerged as a major contributor to obesity, systemic inflammation, and metabolic disease. Furthermore, intestinal bacteria are crucial players in the gut-brain axis, regulating a broad range of central nervous system processes, from satiety mechanisms to anxiety and social behavior. Thus, targeting the microbiome is being actively investigated as a therapeutic strategy for a wide array of diseases, including obesity, anxiety, depression, and autism. Among all intestinal bacteria, Bifidobacterium animalis spp. lactis (BAL) has shown promise for obesity treatment in experimental animal models and human subjects, improving body composition and metabolic health, and reducing energy intake. Moreover, tryptophan metabolism, a crucial regulator of satiety mechanisms and anxiety, is a main target of BAL. Given that clinical manifestations of Prader-Willi syndrome (PWS) include hyperphagia, anxiety, altered body composition, and metabolic dysregulation, the aforementioned effects of BAL might prove highly beneficial for children with PWS. Here, the investigators will test this hypothesis by performing a randomized double-blinded placebo-controlled crossover clinical study to assess the effects of BAL supplementation on an array of clinical manifestations of PWS. Children with PWS will undergo a 3-month placebo/probiotic treatment period, a 3-month washout period, followed by a 3-month probiotic/placebo supplementation. Anthropometric, biochemical, and psychological data as well as biological samples will be obtained at the beginning of the study, and after each of the study periods, with a total of four time-points. Specifically, the investigators will determine body composition by DXA analysis; metabolic health by assessing glucose and lipid metabolic parameters as well as circulating hormonal and cytokine levels; thermoregulation by non-invasive thermal imaging; and hyperphagia and emotional and behavioral problems by applying parental-rated validated questionnaires.
