HyperCKemia in Guillain-Barr é Syndrome

The aim of the present study was to investigate the frequency and clinical features of Guillain-Barr é syndrome (GBS) with hyperCKemia. We retrospectively identified 139 patients with GBS at 2 teaching hospitals in South Korea. We excluded patients with Miller-Fisher syndrome (n = 19), acute bulbar palsy (n = 3), and those whose serum creatine kinase (CK) levels were not measured (n = 45). Twelve of 72 patients (16.7%) had transient hyperCKemia, defined as serum CK ≥300 IU/L. The frequency of male sex and non-demyelinating electrodiagnostic features were higher in patients with hyperCKemia than those without. Transient hyperCKemia, occasionally seen in patients with GBS may be associated with the non-demyelinating subtype.Eur Neurol
