Show moreBackground: Guillain-Barre ' syndrome (GBS) has a highly variable clinical course and outcome as indicated by the risk of developing respiratory failure and residual inability to walk. Prognostic models as Erasmus GBS Respi-ratory Insufficiency Score (EGRIS) developed in adult patients are inaccurate in children. Our aim was to determine the prognostic factors of respiratory failure and inability to walk in children with GBS and to develop a new clinical prognostic model for individual patients (EGRIS-Kids).Methods: A multicenter retrospective cohort study was performed using the data of children (younger than 18 years) fulfilling the diagnostic criteria for GBS from the NINDS. This study was performed in two independent cohorts from centers in Germany, Switzerland, Austria (N = 265, collected 1989-2002) and The Netherlands (N = 156, collected 1987-2016). The predicted main outcomes were occurrence of respiratory failure during the disease course and inability to walk independent at one year after diagnosis. Results: In the combined cohort of 421 children, 79 (19%) required mechanical ventilation and one patient died. The EGRIS-kids was developed including: age, cranial nerve involvement and GBS disability score at admission, resulting in a 9 point score predicting risks of respiratory failure ranging from 4 to 50% (AUC = 0.71). A lower GBS disability score at nadir was the strongest predictor of recovery to independent walking (at one month: OR 0.43 95%CI 0.25-0.74).Conclusions: EGRIS-Kids and GBS disability score at admission accurately predict the risk of respiratory failure and inability to walk respectively in children with GBS, as tools to personalize the monitoring and treatment.
