Dysautonomia in Guillain-Barré Syndrome: Prevalence, Clinical Spectrum, and Outcomes
Neuro Trauma and Critical Care
P9 - Poster Session 9 (5:30 PM-6:30 PM)
1-004
GBS, when severe, involves the autonomic nervous system. Dysautonomia in GBS has been described in up to two-thirds of patients in older series, but it is unclear what its frequency is in current practice.
To assess the contemporary prevalence of dysautonomia in patients with Guillain-Barré syndrome (GBS), the spectrum and relative frequency of different manifestations of autonomic dysfunction, and how it may impact functional outcomes.
A retrospective review of patients admitted to the Mayo Clinic in Rochester, MN between January 1, 2000, and December 31, 2017, with GBS and dysautonomia was performed. Demographics, comorbidities, parameters of dysautonomia, clinical course, GBS disability score, and Erasmus GBS Outcome Score (EGOS) at discharge were recorded.
One hundred eighty seven patients were included with 71 (38%) noted to have at least one manifestation of dysautonomia. Sex and age were not associated with dysautonomia. There were 134 (72%) patients with a demyelinating form of GBS and 48 (36%) patients with demyelination had dysautonomia. Ileus (42%), hypertension (39%), hypotension (37%), fever (29%), tachycardia or bradycardia (27%), and urinary retention (24%) were the most common features. Quadriparesis (P<0.001, OR 2.99, CI 1.57-5.69), bulbar weakness (P<0.001, OR 2.86, CI 1.54-5.30), neck flexor weakness (P<0.001, OR 4.51, CI 2.25-9.05), and mechanical ventilation (P<0.001, OR 6.93, CI 3.39-14.15) were associated with autonomic dysfunction. Patients with dysautonomia more commonly had cardiogenic complications (P=0.01, OR 10.62, CI 1.25-90.11), SIADH (P=0.004, OR 3.34, CI 1.43-7.78), PRES (P=0.03, OR 8.71, CI 0.99-76.17), higher GBS disability score (P<0.001), and EGOS (P<0.001). Mortality was 6% in patients with dysautonomia versus 2% in the entire cohort (P=0.02).
Dysautonomia in GBS is a manifestation of more severe involvement of the peripheral nervous system. Accordingly, mortality and functional outcomes are worse. There is a need to investigate if more aggressive treatment is warranted in this category of GBS.
