HIGH LONG-TERM DRUG-FREE REMISSION RATE FOR ACUTE VOGT-KOYANAGI-HARADA DISEASE WITH AN APPROPRIATE IMMUNOSUPPRESSIVE...

Area of Science:

• Ophthalmology
• Immunosuppression Therapy
• Autoimmune Diseases

Background:

• Vogt-Koyanagi-Harada (VKH) disease is a rare autoimmune condition affecting multiple organs, primarily the eyes.
• Acute VKH disease requires prompt and effective immunosuppressive treatment to prevent vision loss.
• Understanding risk factors for prolonged disease course is crucial for optimizing patient management.

Purpose of the Study:

• To evaluate the clinical outcomes of acute Vogt-Koyanagi-Harada disease treated with a strict immunosuppression regimen.
• To identify risk factors associated with a prolonged disease course in patients with VKH disease.

Main Methods:

• A cohort of 101 patients with acute VKH disease were followed for over 24 months.
• Treatment involved a strict oral prednisone tapering protocol.
• Patients were categorized based on disease recurrence: long-term drug-free remission or chronic recurrent.

Main Results:

• 95% of patients achieved long-term drug-free remission.
• 90.6% of patients achieved best-corrected visual acuity of 20/25 or better.
• Time of visit, ocular complications, and cigarette smoking were identified as independent risk factors for a longer disease course.

Conclusions:

• A carefully managed immunosuppressive regimen with appropriate tapering can achieve high rates of long-term remission in acute VKH disease.
• Cigarette smoking is a significant risk factor, associated with prolonged inflammation and increased treatment requirements.
