Adaptive immune response to therapy in hmgcr autoantibody myopathy.

Journal Article (Journal Article)

INTRODUCTION: We evaluated the response to immunosuppression in a case of 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR)-autoantibody myopathy. METHODS: T- and B-cell subsets were determined by flow cytometry pre- and posttherapy. RESULTS: Baseline immune profiling demonstrated strikingly elevated T-follicular helper (Tfh) cells and plasmablasts. Immunosuppression resulted in clinical improvement and decreased Tfh cells, plasmablasts, and autoantibodies. CONCLUSIONS: Immune profiling in HMGCR-autoantibody myopathy suggests a B-cell-mediated disease. Tfh cells and plasmablasts may be therapeutic biomarkers.
