Recent developments in the medical treatment of thyroid eye disease.
No real new treatment has been developed in the last decade for thyroid eye disease (TED). Glucocorticoids (GC), orbital radiotherapy (OR) or a combination of both, are most frequently used in the treatment of TED for the iv immunosuppressive effects. However, we now have novel information regarding the when and how corticosteroids should be used. In general, the iv route of GC administration is preferable to the oral use. iv GC should be used at much lower doses than previously (4.5 to 6 g cumulative dose), possibly with a small dose of oral prednisone (or equivalent) in the interpulse period and for a few weeks after completion of iv treatment. Careful assessment of patients before treatment for identification of possible risk factors of liver toxicity is mandatory. Finally, monitoring of patients, particularly for liver function, is warranted during and after treatment. Although OR's effectiveness was disputed by a study few years ago, more recent studies have reconfirmed its beneficial role in TED and shown that it still has a positive role to play in patients with active TED. Finally, although Somatostatin-analogs (SM-as) gave the impression some years ago that might represent an effective weapon for TED management and initial, mostly uncontrolled and non-randomized trials with small number of patients supported this notion, newer randomized, double-blind studies with larger number of patients have not confirmed the first optimistic results. The question after that is if SM-as should be considered as a rubber bullet in the treatment of TED and we have to forget about them. The answer should be "no yet," especially in the light that the role of SM-as may be revitalized by the use of analogs with higher affinity for all somatostatin receptors subtypes. Such analogs are now available and under investigation in different diseases with very promising results.
