What neurological complications are linked to VEXAS syndrome and relapsing polychondritis?
VEXAS syndrome and relapsing polychondritis are rare conditions that can affect the nervous system, though these complications are not frequent. Relapsing polychondritis typically causes issues like meningitis, encephalitis, cranial nerve palsies, and stroke. VEXAS syndrome adds the risk of problems with peripheral nerves and muscles 25.
What the research says
A review of the literature shows that neurological involvement in relapsing polychondritis most frequently comprises meningitis, encephalitis, cranial nerve palsies, and stroke 2. VEXAS syndrome is additionally characterized by peripheral nerve and muscle involvement, distinguishing it from relapsing polychondritis in this regard 5.
A specific case report describes a patient with VEXAS syndrome and relapsing polychondritis who developed acute right lower extremity weakness and headache. Imaging suggested tumefactive demyelination or acute disseminated encephalomyelitis (ADEM) rather than a stroke 4. The patient later developed partial status epilepticus and became obtunded, illustrating the potential for severe neurological decline 4.
Another study of 40 male patients with VEXAS syndrome noted that while the primary focus was on blood and bone marrow issues, the broader context of autoinflammation implies a risk for multiorgan involvement, which can include neurological systems 1. A separate cohort of 16 Chinese patients with VEXAS syndrome also documented typical autoinflammation-associated multiorgan involvement, though specific neurological details were less emphasized in that group 3.
What to ask your doctor
- What specific neurological symptoms should I watch for given my diagnosis of VEXAS syndrome or relapsing polychondritis?
- How common are neurological complications like stroke or peripheral nerve issues in my specific condition?
- What signs of meningitis or encephalitis should I report immediately to my care team?
- Are there specific treatments available if I develop neurological symptoms related to my autoinflammatory disorder?
