Guillain-Barré syndrome is a heterogeneous disorder regarding the clinical presentation, electrophysiological subtype and outcome. Previous single country reports indicate that may differ among regions, but no systematic comparative studies have been conducted. Comparative are required to identify factors determining disease susceptibility, variation prognosis, improve diagnostic criteria. The International Syndrome Outcome Study prospective, observational cohort study including all patients...
Abstract Background and purpose Among post‐COVID‐19 symptoms, fatigue is reported as one of the most common, even after mild acute infection, cause fatigue, myopathy diagnosed by electromyography has been proposed in previous reports. This study aimed to explore histopathological changes patients with fatigue. Methods Sixteen (mean age = 46 years) complaints myalgia, or weakness persisting for up 14 months were included. In all patients, quantitative muscle biopsies analyzed light electron...
Guillain-Barré syndrome (GBS) is an acute polyradiculoneuropathy. Symptoms may vary greatly in presentation and severity. Besides weakness sensory disturbances, patients have cranial nerve involvement, respiratory insufficiency, autonomic dysfunction pain. To develop evidence-based guideline for the diagnosis treatment of GBS, using Grading Recommendations, Assessment, Development Evaluation (GRADE) methodology a Task Force (TF) European Academy Neurology (EAN) Peripheral Nerve Society (PNS)...
Background and purpose: For treatment of multifocal motor neuropathy (MMN), we hypothesized that (i) infusion equivalent dosages subcutaneous immunoglobulin (SCIG) is as effective intravenous (IVIG) (ii) at home associated with a better quality life. Methods: In randomized single‐blinded cross‐over study, nine IVIG responsive patients were allocated to receive either SCIG or for period three intervals and, subsequently, crossed over the other treatment. Primary end‐points dynamometric...
We hypothesized that subcutaneous administration of immunoglobulins (SCIG) in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is feasible, safe and superior to treatment with saline for the performance muscle strength.Thirty patients motor involvement maintenance therapy intravenous immunoglobulin (IVIG) fulfilling EFNS/PNS criteria CIDP, aged 18-80 years, were randomized either SCIG at a dose corresponding their pre-study IVIG or given twice thrice weekly 12 weeks home. At...
Abstract Guillain‐Barré syndrome (GBS) is an acute polyradiculoneuropathy with a highly variable clinical presentation, course, and outcome. The factors that determine the variation of GBS are poorly understood which complicates care treatment individual patients. protocol ongoing International Outcome Study (IGOS), prospective, observational, multicenter cohort study aims to identify biological determinants predictors disease onset, subtype, course outcome presented here. Patients...
To investigate the peripheral nerve and muscle function electrophysiologically in patients with persistent neuromuscular symptoms following Coronavirus disease 2019 (COVID-19).Twenty consecutive from a Long-term COVID-19 Clinic referred to electrophysiological examination suspicion of mono- or polyneuropathy were included. Examinations performed 77 255 (median: 216) days after acute COVID-19. None had received treatment at intensive care unit. Of these, 10 not even hospitalized. Conventional...
In the wake of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, an increasing number patients with neurological disorders, including Guillain-Barré (GBS), have been reported following this infection. It remains unclear, however, if these cases are coincidental or not, as most publications were case reports small regional retrospective cohort studies. The International GBS Outcome Study is ongoing prospective observational study enrolling within weeks from onset...
<h3>Background and Objectives</h3> Infections play a key role in the development of Guillain-Barré syndrome (GBS) have been associated with specific clinical features disease severity. The variation GBS across geographical regions has suggested to be related differences distribution preceding infections, but this not studied on large scale. <h3>Methods</h3> We analyzed first 1,000 patients included International Outcome Study available biosamples (n = 768) for presence recent infection...
Abstract Guillain-Barré syndrome is an acute polyradiculoneuropathy in which preceding infections often elicit the production of antibodies that target peripheral nerve antigens, principally gangliosides. Anti-ganglioside are thought to play a key role clinical diversity disease and can be helpful practice. Extensive research into associations individual anti-ganglioside antibody specificities has been performed. Recent highlighted glycolipid complexes, combinations may alter binding, as...
<h3>Background:</h3> In multifocal motor neuropathy (MMN), high dose of IV immunoglobulin (IVIg) is the only established treatment. Subcutaneous self-infusion with G (IgG) (SCIG) increases patient autonomy and treatment flexibility, might be associated fewer side effects due to lower peak IgG levels. a recent study 9 patients MMN, we reported that SCIG preserves muscle strength for few months Five preferred continue after trial another chose apply SCIG. <h3>Methods:</h3> this case series 6...
