Abstract

Purpose

To describe a case of retrobulbar optic neuritis that presented within 3 weeks of adalimumab treatment initiation.

Methods

This index case was evaluated with visual field testing, brain magnetic resonance imaging, lumbar puncture, and laboratory evaluation, and treated with intravenous methylprednisolone followed by a steroid taper.

Results

Our patient made a full visual recovery, but was found to have extensive T2/FLAIR foci of hyperintensities that enhanced and had restricted diffusion on magnetic resonance imaging (MRI). Six months later, these demyelinating lesions still persisted and our patient was initiated on immunomodulatory treatment.

Conclusion

With the extensive burden of disease at presentation and persistence of lesions on follow-up MRI, this unusual case seems to suggest an unmasking of an underlying demyelinating process by adalimumab. The clinician should be mindful of this association and monitor for any manifestations and treat appropriately.

Association between tumor necrosis factor-alpha and disease progression in patients with multiple sclerosis.

R Hentges, M. K. Sharief (1991)

Cachectin, or tumor necrosis factor-alpha (TNF-alpha), is a principal mediator of the inflammatory response and may be important in the pathogenesis and progression of multiple sclerosis, an inflammatory disease of the central nervous system. In a 24-month prospective study, we used a sensitive enzyme-linked immunosorbent assay to determine levels of TNF-alpha in cerebrospinal fluid and serum in 32 patients with chronic progressive multiple sclerosis and in 20 with stable multiple sclerosis and 85 with other neurologic diseases. An attempt was made to relate TNF-alpha levels with the degree of disability of the patients with multiple sclerosis and with their neurologic deterioration during the 24 months of observation. High levels of TNF-alpha were found in the cerebrospinal fluid of 53 percent of the patients with chronic progressive multiple sclerosis and in none of those with stable multiple sclerosis (P less than 0.001). TNF-alpha was detected in the cerebrospinal fluid of 7 percent of the controls (P less than 0.01) with other neurologic disease. In patients with chronic progressive multiple sclerosis, mean TNF-alpha levels were significantly higher in the cerebrospinal fluid than in corresponding serum samples (52.41 vs. 11.88 U per milliliter; range, 2 to 178 vs. 2 to 39; P less than 0.001). In these patients, cerebrospinal fluid levels of TNF-alpha correlated with the degree of disability (r = 0.834, P less than 0.001) and the rate of neurologic deterioration (r = 0.741, P less than 0.001) before the start of the study. Cerebrospinal fluid levels also correlated with the increase in neurologic disability after 24 months of observation (r = 0.873, P less than 0.001). These data provide evidence of intrathecal synthesis of TNF-alpha in multiple sclerosis and suggest that the level of TNF-alpha in cerebrospinal fluid correlates with the severity and progression of the disease. Our results suggest that TNF-alpha may reflect histologic disease activity in multiple sclerosis and could be used to monitor outcomes or responses to therapy.

Demyelination occurring during anti-tumor necrosis factor alpha therapy for inflammatory arthritides.

H Crayton, Brian Edwards, Stefan G. Sandberg … (2001)

To review the occurrence of neurologic events suggestive of demyelination during anti-tumor necrosis factor alpha (anti-TNFalpha) therapy for inflammatory arthritides. The Adverse Events Reporting System of the Food and Drug Administration (FDA) was queried following a report of a patient with refractory rheumatoid arthritis who developed confusion and difficulty with walking after receiving etanercept for 4 months. Nineteen patients with similar neurologic events were identified from the FDA database, 17 following etanercept administration and 2 following infliximab administration for inflammatory arthritis. All neurologic events were temporally related to anti-TNFalpha therapy, with partial or complete resolution on discontinuation. One patient exhibited a positive rechallenge phenomenon. Further surveillance and studies are required to better define risk factors for and frequency of adverse events and their relationship to anti-TNFalpha therapies. Until more long-term safety data are available, consideration should be given to avoiding anti-TNFalpha therapy in patients with preexisting multiple sclerosis and to discontinuing anti-TNFalpha therapy immediately when new neurologic signs and symptoms occur, pending an appropriate evaluation.

An antibody to lymphotoxin and tumor necrosis factor prevents transfer of experimental allergic encephalomyelitis

KM McGrath, CM Bergman, S Padula … (1990)

Uncertainty regarding pathogenic mechanisms has been a major impediment to effective prevention and treatment for human neurologic diseases such as multiple sclerosis, tropical spastic paraparesis, and AIDS demyelinating disease. Here, we implicate lymphotoxin (LT) (tumor necrosis factor beta [TNF-beta]) and TNF-alpha in experimental allergic encephalomyelitis (EAE), a murine model of an autoimmune demyelinating disease. In this communication, we report that treatment of recipient mice with an antibody that neutralizes LT and TNF-alpha prevents transfer of clone-mediated EAE. LNC-8, a myelin basic protein-specific T cell line, produces high levels of LT and TNF-alpha after activation by concanavalin A, antibody to the CD-3 epsilon component of the T cell receptor, or myelin basic protein presented in the context of syngeneic spleen cells. LNC-8 cells transfer clinical signs of EAE. When LNC-8 recipient mice were also treated with TN3.19.12, a monoclonal antibody that neutralizes LT and TNF-alpha, the severity of the transferred EAE was reduced, while control antibodies did not alter the disease. The effect of anti-LT/TNF-alpha treatment was long lived and has been sustained for 5 mo. These findings suggest that LT and TNF-alpha and the T cells that produce them play an important role in EAE.
