Hello, i read carefully your question. Hashimoto encephalopathy is an autoimmune disease which is associated with thyroiditis. Patients with this condition respond most of the times very well to the corthycosteroid therapy, and that s why the condition is also known as steroid responsive encephalopathy associated with autoimmune thyroiditis. In the cases that the steroid therapy isn t successful, immunosuppressors are used like azathioprine, methotrexate, cyclophosphamide or even plasmapheresis or intravenous immunoglobulines. When taking azathioprine, like any other immunosuppressor , one must be very careful about the skin, because the risk of suffering from skin cancer is greater during this kind of treatmet. You have to use very high sunprotection (over 30 uv factors), avoid sunbathing especially the midday hours (11am-3pm). Also, even if you re getting good care of your skin you have to control frequently, every week) if there are chenges in your ski, and you have to report any skin lesion or new scars to your doctor and the dermatologist. I hope i ve been of help. You can contact me again for further questions, i would be pleased to assist you.
