Abstract:
A 48-year-old man with rapid onset of fever elevation developed acute myelitis over a period of a week. MRI of the spinal cord revealed a longitudinal T2-hyperintense intraspinal lesion extending from C6 to Th8 level. Clinical symptoms and findings resolved with immunotherapy. In serological analysis, no antibodies related to various collagen diseases, anti-aquaporin-4 (AQP4) antibody and anti-myelin oligodendrocyte glycoprotein (MOG) antibody were detected. Anti-lactosylceramide (LacCer) antibodies were detected in the acute phase of serum and cerebrospinal fluid, with titers showing decrements in the recovery phase. The present case supports the notion that acute myelitis can occur as an anti-neutral glycolipid antibody-related disorder. Anti-neutral glycolipid antibodies should be examined in future pertinent cases of myelitis.
Insights
Acute myelitis can be linked to anti-neutral glycolipid antibodies, specifically anti-lactosylceramide (LacCer) antibodies. Testing for these antibodies is recommended for patients with myelitis.
Area of Science:
- Neurology
- Immunology
- Neuroimmunology
Background:
- Acute myelitis is a neurological condition characterized by inflammation of the spinal cord.
- Differential diagnosis of myelitis includes autoimmune disorders and infections.
- Standard autoimmune markers like anti-aquaporin-4 (AQP4) and anti-myelin oligodendrocyte glycoprotein (MOG) antibodies are often tested.
Observation:
- A 48-year-old male presented with acute myelitis and a T2-hyperintense spinal cord lesion.
- Initial serological tests for collagen diseases, AQP4, and MOG antibodies were negative.
- Anti-lactosylceramide (LacCer) antibodies were detected during the acute phase and decreased during recovery.
Findings:
- The patient's symptoms resolved with immunotherapy.
- The presence of anti-LacCer antibodies suggests a role for anti-neutral glycolipid antibodies in myelitis.
- Titers of anti-LacCer antibodies correlated with disease activity.
Implications:
- This case highlights anti-neutral glycolipid antibodies as a potential cause of acute myelitis.
- Routine screening for anti-neutral glycolipid antibodies may be warranted in unexplained myelitis cases.
- Further research into anti-glycolipid antibody-associated neurological disorders is suggested.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
