Background: Despite the publication of the 2020 guidelines on how to manage Rett Syndrome (RS), some fundamental topics are still open, in particular respiratory problems.
Objective: Identification and reinforcement of current recommendations concerning the management of respiratory issues in RS patients.
Materials and methods: Using a Delphi approach, the leading group reviewed the literature and formulated 14 statements. A multidisciplinary panel of 29 experts were invited to score, for each statement, their agreement on a 1-5 scale. The cut-off level for consensus was 75%, obtained through multiple rounds.
Results: The panel agreed that in all RS types, respiratory issues should be faced at an early stage, regardless of epilepsy onset. It is recommended to perform periodically sleep studies in all Congenital Rett Syndrome, and in selected cases with other RS types. Noninvasive ventilation should be considered in all RS subjects with sleep respiratory disorders and in those with hypotonia associated with hypercapnia. Chest physiotherapy should be performed in all RS patients with difficult management of the accumulation of respiratory secretions, using airway clearance techniques and devices (PEP-mask, AMBU bag, or cough machine), more appropriate and tolerated by the patients. The panel recommended individualized programs for the management of scoliosis, and to consider performing gastrostomy in patients at increased risk of ab ingestis pneumonia.
Conclusions: This consensus could support everyday clinical practice on respiratory issues in RS patients, complementary to existing recommendations by regulatory agencies and guidelines.
