Distribution characteristics of antinuclear antibodies in Guillain-Barré syndrome and its relationship with disease severity

Guillain-Barré syndrome (GBS), an acquired immune-mediated autoimmune disorder affecting the peripheral nervous system (PNS), is associated with autoimmunity. The presence of autoantibodies in the blood is an important feature of autoimmune diseases. Herein, we explored the distribution characteristics of the antinuclear antibodies (ANAs) in GBS and the correlation between ANAs and disease severity.
