Treatment and Prognosis of Vogt-Koyanagi-Harada Disease: Real-Life Experience in Long-Term Follow-Up

Categories and Profiles of Uveitis in Vogt-Koyanagi-Harada Syndrome With Systemic Correlation: Inferences From a Tertiary Multispecialty Hospital

Introduction Vogt-Koyanagi-Harada (VKH) syndrome is a granulomatous, autoimmune panuveitis, affecting the eyes, ears, skin, and meninges. It can cause choroiditis and can progress to the retina and optic disc causing visual loss. Imaging using fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA), and enhanced depth imaging-ocular coherence tomography (EDI-OCT) is required for clinical evaluation and management. Steroids and immunosuppression are the treatment modalities used. Aim The aim of this study is to report the correlation and severity of uveitis in relation to systemic manifestations. Method A retrospective study including 100 patients with VKH syndrome was carried out. They were classified based on clinical manifestations and investigations such as FFA, ICGA, B-scan ultrasonography (USG), and ocular coherence tomography (OCT). Patients were characterized as complete, incomplete, and probable VKH syndrome. Laboratory investigations were performed, and statistical analysis was done. Results Probable VKH syndrome was found to be the most common form of presentation in our study population. Defective vision was the most common complaint among the patients. Extraocular manifestations included tinnitus, vertigo, alopecia, headache, fatigue, and vitiligo and were seen in 33% of the patients. Disc edema and serous retinal detachment were seen in 85% of the patients. Improvement was noted in 25% of the patients with the use of corticosteroids. Conclusion Response to treatment with systemic corticosteroids and immunosuppression in the acute phase of uveitis is better compared to chronic uveitis. The ophthalmologist is usually first consulted in VKH syndrome due to presenting ocular complaints. A multidisciplinary approach is key to providing holistic management.

Vogt-Koyanagi-Harada disease in pregnancy: Case report and review of 32 patients in the literature

Key Clinical Message

Systemic prednisolone including steroid pulse therapy would be safe in 32 pregnant women, who developed Vogt-Koyanagi-Harada disease in the literature. Prednisolone administration would be shortened by monitoring of serous retinal detachment with optical coherence tomography.

Abstract

A 30-year-old woman in 31 weeks of pregnancy with metamorphopsia and headache was diagnosed Vogt-Koyanagi-Harada disease. She underwent steroid pulse therapy and oral prednisolone 20 mg daily for 3 weeks until complete resolution of serous retinal detachment monitored by optical coherence tomography. Oral prednisolone was tapered and discontinued until uneventful delivery.

Reactivation of previously controlled Vogt-Koyanagi-Harada disease more than 46 years following COVID-19 vaccination: a case study

We report a case of Vogt-Koyanagi-Harada (VKH) disease that recurred 46 years after initial treatment. A 59-year-old woman presented with a 2-month history of bilateral vision blurring. She had received her third dose of coronavirus disease 2019 (COVID-19) vaccination 4 months before the onset of blurring. The best-corrected visual acuity (BCVA) was 1.0 in the right eye and 0.15 in the left eye at the initial visit. Iritis and synechia were observed between the lens and iris bilaterally. A sunset glow fundus was found in both eyes with no serous retinal detachments or disc hyperemia. The patient had a history of VKH disease and had been treated with whole-body corticosteroid administration at another hospital when she was 13 years old. The patient was diagnosed with VKH disease recurrence, and oral corticosteroid therapy and corticosteroid eyedrop treatment were initiated. The treatment response was good. At the time of this writing, recurrence had not been observed for 14 months, and the BCVA was 1.0 in both eyes. To our knowledge, this case represents the longest recorded interval of VKH disease recurrence in the literature to date. COVID-19 vaccination might be the cause of long-term well-controlled disease recurrence.

Vogt-Koyanagi-Harada Disease and COVID

Vogt-Koyanagi-Harada (VKH) is a rare multisystem inflammatory disease affecting the eyes, ears, brain, skin, and hair. The Coronavirus Disease 2019 (COVID-19) is a new contagious infection that might trigger the onset of VKH disease, as previously proposed for other viruses. Moreover, after the mass vaccination against SARS-CoV-2 worldwide, cases of VKH disease associated with COVID-19 vaccination have been reported. We present an overview of VKH and a comprehensive literature revision of all the VKH cases described after COVID-19 infection and vaccination, adding our experience. No differences have been found considering epidemiology and clinical findings of the disease compared to those reported in the no-COVID era. All of the patients promptly responded to systemic and local corticosteroid therapy with a good final visual prognosis. Different possible pathogenetic mechanisms underlying the onset of VKH after COVID-19 vaccination are discussed, while the presence of the HLA DR4 antigen as a genetic predisposition for the onset of the disease after COVID-19 infection and vaccination is proposed. VKH disease is one of the most frequently reported uveitic entities after COVID-19 vaccination, but a good response to therapy should not discourage vaccination. Nevertheless, ophthalmologists should be alerted to the possibility of VKH occurrence or relapse after COVID-19 vaccination, especially in genetically predisposed subjects.
