Plasma exchange therapy for severe Graves' ophthalmopathy

Area of Science:

• Endocrinology
• Immunology
• Ophthalmology

Background:

• Graves' disease is an autoimmune disorder that can lead to severe ophthalmopathy.
• Severe Graves' ophthalmopathy significantly impacts patient quality of life and vision.

Purpose of the Study:

• To evaluate the efficacy of intensive plasma exchange followed by immunosuppression in treating severe Graves' ophthalmopathy.

Main Methods:

• 11 patients with severe Graves' ophthalmopathy underwent intensive plasma exchange.
• Immunosuppressive therapy was administered post-plasma exchange.
• Ophthalmopathy index and orbital CT scans were used for pre- and post-treatment evaluation.

Main Results:

• 91% of patients showed favorable treatment outcomes.
• Significant improvements were noted in soft tissue involvement, proptosis, tonometry, and visual acuity.
• Enlarged extraocular muscles demonstrated reduced size and density on CT scans.

Conclusions:

• Intensive plasma exchange combined with immunosuppression is an effective treatment for severe Graves' ophthalmopathy.
• The treatment provides rapid and sustained improvement in most patients.
• Recurrences were successfully managed with repeat treatment courses.
