METABOLIC SYNDROME, BLIND
Bacteriophages (phages) are bacterial viruses that have been shown to shape microbial communities. Previous studies have shown that faecal virome transplantation can decrease weight gain and normalize blood glucose tolerance in diet-induced obese mice. Therefore, we performed a double-blind, randomised, placebo-controlled pilot study in which 24 individuals with metabolic syndrome were randomised to a faecal filtrate transplantation (FFT) from a lean healthy donor (Bacteriophages (phages) can modify the gut microbiome to benefit human health. Here, the authors report the results of a double blind, randomized, placebo-controlled trial, showing that faecal filtrate transplantation (FFT), containing phages from lean healthy donors, is safe and improves glycemic variability in patients with metabolic syndrome, while shifting the gut phage composition.
