An observational study in Hyperuricemia, sponsored by Örebro University, Sweden. Recruiting at 1 site in Sweden. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2025-08-12.
Sponsored by Örebro University, Sweden · Observational
In this study, we will collect faecal samples from individuals with hyperuricaemia (assessed by blood test) and perform in vitro faecal fermentation studies to assess how probiotics in combination with fibres affect urate metabolism in these faecal samples.
In this study, the investigators will collect blood samples to check if recruited participants have hyperuricemia, and if yes, stool samples will be collected for laboratory faecal fermentation tests. The research project aims to investigate the effects of probiotics and dietary fibers on stool samples, to understand if and how they can support the gut microbiota to break down uric acid in the gut.
Participation in the study involves data collection and sampling on three occasions. During the first visit, participants will provide a blood sample, and if they have increased urate levels, they will be asked to complete questionnaires and be provided with materials for stool sampling during the second visit. During the third visit, they will provide the stool sample, which will then be used in the faecal fermentation experiments, where different fibres (beta-glucans) will be tested in combination with probiotics.
