Clinical Response to Tocilizumab in Severe Thyroid Eye Disease

Tocilizumab, in a preliminary study, was reported to be an effective therapy for moderate to severe thyroid eye disease. The authors describe the clinical response of 2 severe thyroid eye disease cases refractory to intravenous steroids and orbital decompression. Both patients demonstrated improved clinical activity scores with minimal side effects after tocilizumab therapy. In addition, post tocilizumab orbital fat biopsies demonstrated benign adipose tissue without evidence of inflammatory cells.
