CD40LG and peripheral neuropathy: Previous studies showed that anti-Sulfatide antibodies are associated with several subtypes of peripheral neuropathy, predominantly sensory or sensorimotor axonal neuropathies are most common,[5] which may also exist in AMAN.[6] Fan et al proposed that IgG anti-GM1 antibodies are associated with AMAN, and IgM antibodies of GM1, GM2, and GM3 are associated with facial nerve palsy in Chinese patients.[7] Although GM1 antibodies are not specific for GBS, GM1 antibodies can be elevated in patients with AMAN, and anti-GM1 and GM3 antibodies may be associated with facial nerve palsy.
