Protective Role of Pre-/ Post-biotics on Gut Inflammation, Dysbiosis, and Life Quality in Rett Syndrome (Biotics_RTT)

Pre- and post-biotic supplementation will be administered for 3 month period (i.e. 12 weeks) given the filling out of a supplementation diary by parents/caregivers. At the scheduled visits/ phone contacts (i.e., baseline, 4 weeks and 12 weeks), systemic inflammation, intestinal inflammation, and gut microbiome characterization as well as treatment compliance, clinical and dietary intake will be assessed. A seizure diary will be provided to parents/caregivers in order to check the frequency and entity of the critical episodes. An EEG recording will be performed at enrollment (or within 6 months prior to the baseline visit).
