Neurological Complications of Therapeutic Monoclonal Antibodies: Trends from Oncology to Rheumatology.

Purpose Of Review: This review is to describe the scope of neurological complications associated with monoclonal antibody-based therapies, applied across medical specialties, to demonstrate the common and rare neurological syndromes that may be encountered in clinical practice according to the therapeutic agent being receive, and to explain appropriate work-up, diagnosis, and management of drug complications, as supported by the literature.

Recent Findings: The number of commercially available, evidence-based therapeutic monoclonal antibodies continues to expand. In oncology, immune checkpoint inhibitors are particularly important, as a wide range of central and peripheral nervous system complications are described. In rheumatology, anti-TNF alpha drugs remain associated with demyelinating syndromes. The number of therapeutic monoclonal antibodies encountered in practice continues to grow, as does the number of described neurological complications. Recognition of a possible drug complication is key, as these are typically complex patients at risk of other causes of neurological injury. Identification of a complication of therapy often leads to intervention and a change in management.
