Tumor necrosis factor alpha neutralization seems a rational therapy for myositis because this proinflammatory cytokine has been implicated in the pathogenesis of this disorder. Until now, we have treated 2 patients with a chimeric anti-TNF-alpha monoclonal antibody (infliximab). Both patients demonstrated a marked and sustained subjective and objective improvement without the occurrence of any side effects. These preliminary results suggest that anti-TNF-alpha treatment with infliximab is a safe and rapidly effective therapy for myositis.
