Anti-TNFa treatment has been related to CNS demyelination, while history of demyelinating disease is considered as contraindication to anti-TNFa use. The aim of this study was to describe 3 patients with Crohn's disease (CD), who presented with neurological symptoms and had demyelinating lesions of white matter in brain MRI, while receiving treatment with anti-TNF agents.
We reviewed past medical history, clinical presentation, hospitalisation history, type and duration of anti-TNFa treatment and brain MRI results of the 3 patients.
Patient A (CD diagnosis 6 years ago) presented with right lower limb numbness 2 years after commencing adalimumab therapy. Brain MRI showed few, non-significant white matter lesions. Infliximab was started 3 years later, after R colectomy-syringectomy-anastomosis, with relapse of the neurological symptoms.. Patient B (CD diagnosis 3 years ago) developed right side (face and upper-lower limb) 2 years after adalimumab therapy. Patient C (CD diagnosis a year ago) reported right eye pain occasionally for 4 years with negative ophthalmologic evaluation. A year after commencing therapy with Infliximab-bio and azathioprine, relapse of eye pain and new-onset limb numbness were reported. Brain MRI in all patients demonstrated white matter lesions. The radiological differential diagnosis included microangiopathic or demyelinating lesions. Anti-TNFa therapy was discontinued in all 3 patients with subsequent remission of the symptoms but without full disappearance.
Numbness is reported relatively frequently in CD patients receiving anti-TNFa treatment. The current series demonstrate the difficulty of establishing a firm causal association with the use of anti-TNF treatment due to the absence of earlier imaging. Therefore, we propose that brain-MRI may be considered in IBD patients before starting biological therapy.
