Brief Summary

Guillain-Barre syndrome is an immune-mediated acute inflammatory peripheral neuropathy. The currently effective treatment methods include intravenous immunoglobulin and plasma exchange. Immunoadsorption has been widely used to treat immune-related diseases. There are currently no prospective large-sample clinical trials of immunoadsorption therapy for Guillain-Barre syndrome. The neuro-intensive care unit of the First Affiliated Hospital of Zhengzhou University is preparing to carry out a prospective, multi-center, randomized parallel controlled clinical study on the efficacy and safety of protein A immunoadsorption and intravenous immunoglobulin (IVIG) in the treatment of Guillain-Barre syndrome. It is estimated that 204 patients with Guillain-Barre syndrome will be included. The patients will be randomly assigned to the immunoadsorption group and the IVIG group. The primary outcome measure: changes in Hughes scores (4 weeks after starting treatment vs. baseline (before starting treatment) ). This study aims to explore the efficacy and safety of protein A immunoadsorption and intravenous immunoglobulin in the treatment of Guillain-Barre syndrome.

Outcome Measures

Primary Outcomes (1)

  • Changes in Hughes scores

    Compared with the patient's Hughes score before treatment, the change of Hughes scores 4 weeks after the start of protein A immunoadsorption or intravenous immunoglobulin treatment.

    4 weeks after starting treatment vs. baseline (before starting treatment)

Secondary Outcomes (6)

  • Changes in Hughes scores

    2 weeks after starting treatment vs. baseline (before starting treatment)

  • Reached Hughes Grade 2

    From date of first treatment until the date of patient's recovery to Hughes Grade 2 or end date of clinical trial, whichever came first, assessed up to 4 weeks.

  • Ventilator application time

    For patients who require ventilator-assisted ventilation, from date of start use ventilator until participants leave the ventilator or end date of clinical trial, whichever came first, assessed up to 4 weeks.

  • Total time in ICU

    From the date the patient enters the ICU until the patient leaves the ICU or the clinical trial ends, whichever came first, assessed up to 4 weeks.

  • Changes of total lymphocyte count, interleukin-6, interleukin-8, cerebrospinal fluid protein

    2 weeks after starting treatment vs. baseline (before starting treatment)

  • +1 more secondary outcomes

Study Arms (2)

Immunoadsorption group

EXPERIMENTAL

Protein A immunoadsorption therapy

Device: immunosorbent column

intravenous immunoglobulin group

ACTIVE COMPARATOR

Treatment with intravenous immunoglobulin

Drug: intravenous immunoglobulin

Interventions

Immunoadsorption treatment regimen: the treatment is performed once every 1-3 days, at least 5 times, and the amount of regenerated plasma for each treatment is 1 to 3 times the plasma volume. The immunosorbent column adopts the protein A immunosorbent column.

Also known as: Protein A Immunoadsorption
Immunoadsorption group

Intravenous immunoglobulin treatment regimen: intravenous immunoglobulin therapy, 400mg/kg/d, once a day, for at least 5 consecutive days.
