Concurrent use of tumor necrosis factor inhibitor and tyrosine kinase inhibitor in ankylosing spondylitis and myeloid neoplasm

Abstract

<jats:p>Biologic disease-modifying agents (bDMARDs) are highly effective in controlling the symptoms of autoimmune rheumatic diseases. The decision on whether to continue bDMARDs following a cancer diagnosis can be challenging for patients and physicians. Here, we describe a case of a middle-aged male with ankylosing spondylitis who was controlled on infliximab (IFX) and found to have a myeloid neoplasm with Platelet-Derived Growth Factor Receptor Beta rearrangement. The patient was started on a tyrosine kinase inhibitor imatinib. Given its significant positive effect on patient’s quality of life, IFX was continued with a favorable outcome. This case highlights the importance of shared decisionmaking in balancing risks and benefits of immunosuppressants in appropriate cases of hematologic malignancy.
