Approaches for the diagnosis and treatment of VEXAS syndrome: the importance of clinical suspicion and the use of methotrexate

Ann Hematol. 2024 Nov;103(11):4789-4791. doi: 10.1007/s00277-024-05863-0. Epub 2024 Aug 23.

Abstract

Vacuoles, E1-enzyme, X-linked, Autoinflammatory, Somatic (VEXAS) syndrome is caused by mutations in the UBA1 gene in myeloid precursors, leading to systemic inflammatory manifestations. We present the case of a 75-year-old man presenting with fever, panniculitis, and macrocytic anemia testing repeatedly negative for UBA1 mutations in peripheral blood samples, but ultimately found positive on bone marrow mononuclear cell DNA. The man has been successfully treated with prednisone and methotrexate.

Keywords: Ageing; Autoinflammatory syndrome; Bone marrow; Immunology; Sanger sequencing.
