Guillain-Barrè Syndrome-Retrospective Analysis of Data from a Cohort of Patients Referred to a Tertiary Care Pediatric Neuromuscular Center from 2000 to 2017: Electrophysiological Findings, Outcomes, and a Brief Literature Review.

Guillain-Barré syndrome (GBS) is the most frequent cause of acute flaccid paresis in children. The aim of this study was to describe the clinical and electrophysiological findings and outcomes of children with GBS diagnosed in our unit. Moreover, the literature on pediatric GBS cases from the past 5 years was reviewed. In this retrospective study, we reported data on 12 patients (9 male and 3 female patients; mean age: 5 y, 4 mo; range: 9 mo-11 y) clinically diagnosed at the Child Neurology Unit of the AUSL-IRCCS of Reggio Emilia, Italy, between 2000 and 2017 and a brief analysis/comparison with data from the literature. Data were collected from medical charts. In our cohort, male patients were more frequent than female ones (9 vs. 3), and upper respiratory tract infection (n = 8, 66.7%) was the most frequent triggering factor. The main clinical symptoms on admission were distal lower limbs' weakness with gait difficulties (83.3%), pain (50%), upper limbs' weakness (50%), and dysphagia for liquids (25%). Peripheral neurophysiological studies revealed acute inflammatory demyelinating polyradiculoneuropathy (AIDP) in 66.6% of the children, acute motor and sensory axonal neuropathy (AMSAN) in 25%, and acute motor axonal neuropathy (AMAN) in 8.3%. Ten individuals (83.3%) received timely treatment with intravenous immunoglobulins (IVIG), and, out of these ten patients, 58% received concomitant treatment with IV methylprednisolone because of a progressive disease course. Complete remission was observed in the majority of individuals (91.6%) within 6 months of symptom onset. Different subtypes of GBS can affect children; however, the outcome is usually positive. Early treatment appears to be important for a favorable outcome.
