Vogt-Koyanagi-Harada disease: a retrospective and multicentric study of 41 patients

Managing Vogt–Koyanagi–Harada disease during pregnancy with steroid pulse therapy: A case report

BACKGROUND

High-dose steroid administration is a common initial therapeutic approach for Vogt–Koyanagi–Harada disease (VKH). Nonetheless, administering substantial doses of steroids to pregnant women necessitates meticulous consideration due to the potential impacts on the mother and fetus. We present a case wherein steroid pulse therapy was administered to a patient who developed VKH during the late stages of pregnancy.

CASE SUMMARY

The patient was a 26-year-old nulliparous woman. At 33 weeks and 1 day of her pregnancy, she experienced a decline in visual acuity and noticed metamorphopsia in her left eye. Examination revealed bilateral serous retinal detachment, leading to VKH diagnosis. A collaborative effort involving the departments of ophthalmology, internal medicine, and neonatology was initiated. Steroid pulse therapy was administered at 34 weeks and 1 day of pregnancy under hospital supervision. Complications, such as threatened preterm labor and gestational diabetes, emerged, necessitating the initiation of oral ritodrine hydrochloride and insulin therapy. Then, serous retinal detachment was resolved, and visual acuity was restored. Labor pains initiated 32 days post-initiation of steroid pulse therapy (at 38 weeks and 4 days of gestation), culminating in a normal delivery. Mother and newborn experienced an uneventful puerperal course and were discharged from the hospital on the 5th day following delivery.

CONCLUSION

VKH management in pregnancy requires multidisciplinary coordination, emphasizing collaboration with ophthalmologists and specialists in internal medicine and neonatology.

The Incidence and Presentation Features of Glaucoma in Vogt-Koyanagi-Harada Syndrome: A Systematic Review and Meta-Analysis

TOPIC

To determine the cumulative incidence and features of glaucoma in patients with Vogt-Koyanagi-Harada (VKH) syndrome compared with nonglaucoma patients.

CLINICAL RELEVANCE

Knowing the exact burden of secondary glaucoma in VKH could guide its screening and management in clinical practice as a part of the regular follow-up for patients with VKH.

METHODS

The review protocol was preregistered on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PROSPERO) [CRD42023462794]. PubMed, Scopus, Web of Science, EBSCOhost, and Google Scholar were searched for studies reporting the cumulative incidence and features of glaucoma presentation in VKH. A manual search was also conducted to supplement the primary search. Subgroup analyses based on glaucoma type, VKH stage, and patients' age were conducted. All analyses were conducted using STATA. Fixed- and random-effects models were selected according to the observed heterogeneity. Studies' methodological quality was determined using the National Institutes of Health tool.

RESULTS

The analysis of 7084 eyes revealed a progressive increase in the cumulative incidence of secondary glaucoma over time. The cumulative incidence was lowest at VKH onset (7%) and highest at 15 years (26%). Open-angle (12%; 95% confidence interval [CI]: 9%-14%) is more common than angle-closure glaucoma (7%; 95% CI: 3%-13%). Glaucoma cumulative incidence is highest in the chronic recurrent stage of VKH (33%; 95% CI: 12%-59%) and among children < 18 years of age (26%; 95% CI: 16%-37%). Features associated with glaucoma occurrence in VKH showed comparable rates with nonglaucoma cases. However, a meta-analysis to determine risk factors of glaucoma development in VKH was not feasible secondary to the lack of adjusted risk measures in included studies. Studies' quality was questionable in 5 studies. The certainty of evidence was moderate-to-high.

CONCLUSION

The cumulative incidence of glaucoma increases throughout VKH's course, with a higher tendency in children, chronic recurrent stages, and long-term follow-up. Future research should focus on examining risk factors of glaucoma development in VKH through adjusted multivariable regression models.

Impact of Initial Management on Disease Evolution in Vogt-Koyanagi-Harada Syndrome: A Retrospective Cohort of 50 Patients

PURPOSE

The study aims to determine the impact of initial management in Vogt-Koyanagi-Harada syndrome (VKHS).

METHODS

Patients diagnosed with a VKHS between January 2001 and December 2020 in two French tertiary centers were included in a retrospective study.

RESULTS

Fifty patients were included with a median duration of follow-up of 29.8 months. All patients received oral prednisone after methylprednisolone in all but four of them. Five patients received at least one associated immunosuppressive therapy (IST) within the first 6 months and 26 patients received IST during the entire follow-up period. Twenty-eight patients presented at least one relapse at a median of 5.4 months from diagnosis. Multivariate analyses demonstrated a significant association between relapse and delayed treatment (>26 days) (HR = 3.69, CI95% 1.30-10.47, p = .01), whereas no association was observed between relapse and the number of corticosteroid pulses at initial management.

CONCLUSION

An early corticosteroid treatment within the first 26 days of symptoms decreased the relapse rate.

Vogt-Koyanagi-Harada Disease: The Clinical Spectrum and Management of Case Series in a Tertiary Eye Centre in Northern Part Of Malaysia

AIMS

We present the clinical spectrum, the initial clinical presentation with management trends in treating 14 Vogt-Koyanagi-Harada (VKH) disease cases in a tertiary center in the Northern part of Malaysia.

CASE SERIES

There were 14 cases of Vogt-Koyanagi-Harada (VKH) disease retrospectively reviewed over five years (from 2015 to 2020). The mean age at presentation was 37.7 years (range 21-64 years), with female predominance (85.7%). All cases presented with acute uveitic stage and bilateral eye involvement. Of them, 11 (78.6%) were probable VKH, and three (21.4%) were incomplete VKH. All patients attended with acute panuveitis at first presentation. The main posterior segment involvement was disc edema in 57.1% (16 out of 28 eyes) and exudative retinal detachment (ERD) in 35.7% (10 out of 28 eyes). Most of them presented with blindness (3/60 and worse) and moderate visual impair- ment (6/18-6/60); 35.71% each, followed by mild visual impairment (6/12-6/18), and severe visual impairment (6/60-3/60); 7.1% each. Ten patients (71.4%) required combination second-line immunomodulatory treatment during subsequent visits, and only four patients (28.6%) responded well to corticosteroid therapy. Most of the cases achieved no visual impairment (64.3%), followed by mild visual impairment (21.4%) and moderate visual impairment (14.3%), and none were severe or blind at the end of follow-up.

CONCLUSION

VKH is a potentially blinding illness if there is inadequate control of the disease in the acute stage. Most of our patients achieved good visual outcomes with early immunomodulatory treatment and systemic corticosteroids.

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

PURPOSE

To report the clinical profile and outcomes of acute Vogt-Koyanagi-Harada disease with a strict immunosuppression regimen and investigate the risk factors for a prolonged disease course.

METHODS

A total of 101 patients with acute Vogt-Koyanagi-Harada (202 eyes) with more than 24 months of follow-up were recruited from January 2011 to June 2020. They were divided into two groups according to the interval between the onset of Vogt-Koyanagi-Harada and treatment. Oral prednisone was gradually tapered off by a diminished dose according to a relatively strict protocol. Patient responses to the treatment regimen were classified as long-term drug-free remission or chronic recurrent.

RESULTS

Ninety-six patients (95.0%) achieved long-term drug-free remission without recurrence, while 5 (5.0%) had chronic recurrence. Most patients achieved good best-corrected visual acuity (90.6% ≧20/25). A generalized estimation equation model demonstrated that time of visit, ocular complications, and cigarette smoking were independent risk factors for a longer disease course, and smokers required a higher drug dose and longer treatment course than nonsmokers.

CONCLUSION

An immunosuppressive regimen with an appropriate tapering speed can lead to long-term drug-free remission in patients with acute Vogt-Koyanagi-Harada. Cigarette smoking significantly affects ocular inflammation.

Autoimmune Meningitis and Encephalitis

Meningitis and encephalitis are inflammatory syndromes of the meninges and brain parenchyma, respectively, and may be identified either by finding definitive evidence of inflammation on tissue pathology or by cerebrocpinal fluid (CSF) analysis showing pleocytosis or intrathecal antibody synthesis. Clinicians evaluating undifferentiated meningitis or encephalitis should simultaneously consider autoimmune, infectious, and neoplastic causes, using patient risk factors, clinical syndrome, and diagnostic results including CSF and MRI findings to narrow the differential diagnosis. If an autoimmune cause is favored, an important early diagnostic question is whether a specific neural autoantibody is likely to be identified.

Uveitis in Children and Adolescents

Childhood noninfectious uveitis leads to sight-threatening complications. Idiopathic chronic anterior uveitis and juvenile idiopathic arthritis-associated uveitis are most common. Inflammation arises from an immune response against antigens within the eye. Ophthalmic work-up evaluates anatomic involvement, disease activity, ocular complications, and disease course. Local and/or systemic glucocorticoids are initial treatment, but not as long-term sole therapy to avoid glucocorticoids-induced toxicity or persistent ocular inflammation. Children with recurrent, refractory, or severe disease require systemic immunosuppression with methotrexate and/or anti-tumor necrosis factor monoclonal antibody medications (adalimumab, infliximab). Goals of early detection and treatment are to optimize vision in childhood uveitis.
