The spectrum of Vogt–Koyanagi–Harada disease in Iran

VKH disease in the elderly: Variations in clinical course as compared to VKH disease in adults

PURPOSE

To describe disease characteristics and outcomes of Vogt-Koyanagi-Harada (VKH) disease in elderly patients.

METHODS

Retrospective analysis of patients older than 50 years with VKH disease at two referral centers in India. Demographics, extraocular and ocular involvement, treatment, complications, and visual acuity outcomes were noted.

RESULTS

In total, 69 patients (mean age at presentation: 56.4 ± 4.7 years) were analyzed; 6/69 patients had diabetes mellitus at presentation, and 10/69 had hypertension. Clinical signs included anterior chamber cells >2+ (29%), granulomatous keratic precipitates (23%), disc hyperemia (26%), neurosensory retinal detachment (34.7%), and "sunset-glow" fundus (52.1%). Patients were classified as probable (n = 50, 72.4%), incomplete (n = 18, 26%), and complete VKH (n = 1, 1.4%). The mean follow-up period was 20.2 ± 19.4 months. Improvement in mean BCVA of (0.63 LogMAR, 6 Snellen lines) was noted on the last follow-up. Patients receiving systemic steroids with immunosuppressants ( P < 0.0001) had better visual outcomes at final follow-up compared to steroids alone ( P = 0.103). Eight patients (11.6%) had complications due to systemic immunosuppressants, and 17 patients (24.6%) developed diabetes mellitus or had worsening of diabetes while on systemic corticosteroids.

CONCLUSION

Few patients presented with systemic manifestations in our cohort. Those treated with steroids and concurrent immunosuppressants had better outcomes. However, therapy with immunosuppressants was encountered with major dose-limiting complications in a significant number of elderly patients with VKH syndrome.

Vogt Koyanagi Harada Disease In Paediatric Age Group: Clinical Characteristics, Remission, Recurrences and Complications in Asian Indian Population

PURPOSE

To describe disease characteristics and outcomes of Vogt-Koyanagi-Harada (VKH) syndrome in paediatric patients.

STUDY DESIGN

Retrospective chart analysis.

METHODS: A RETROSPECTIVE

Analysis of all patients ≤16 years with VKH syndrome was done. Clinical presentations, complications, recurrences and outcomes in cases of paediatric VKH were reviewed.

RESULTS

72 eyes of 36 patients with a mean age at presentation of 13.7 ± 2.34 years were assessed. Mean duration of symptoms and follow up were 9.88 ± 17.3 weeks and 55 months respectively. Clinical signs at presentation included anterior chamber cells >2+(34/72eyes, 47.2%), granulomatous keratic precipitates (6 eyes, 8.3%), posterior synechiae (35 eyes,48.6%), disc edema (46 eyes, 63.8%), neurosensory retinal detachments (44 eyes, 61.1%) and 'sunset-glow' fundus (9 eyes, 12.5%). Best corrected visual acuity (BCVA) at the time of presentation was 1.3logMAR or a Snellens equivalent of 20/400 which improved to 0.51logMAR (Snellens equivalent of 20/63) at last follow up. Remission was achieved in 61.1% cases. More than half of our patients developed one or more complications.

CONCLUSION

VKH in paediatric patients poses a challenge due to a delayed presentation and paediatric VKH patients have a worse visual acuity at the time of presentation as compared to adult age groups. Rates of remission may be low along with high risk of complications and hence there is a need for prolonged immunosuppression.

Vogt-Koyanagi-Harada Syndrome in a Canadian First Nations Population

Purpose: To characterize presentations, characteristics and outcomes of uveitis in Vogt-Koyanagi-Harada (VKH) syndrome in a North American First Nations (FN) population.Methods: Charts of 27 Canadian FN patients with VKH uveitis were retrospectively reviewed to characterize demographics, disease characteristics, management, complications and visual outcomes.Results: Average age at uveitis onset was 30.9 ± 13.8 years. Twenty-six patients 10 (96.3%) were female. Nine patients (33.3%) demonstrated complete VKH, 8 (29.6%) incomplete, and 10 (37%) probable VKH. Systemic associations included integumentary (19 patients, 70%), neurologic (17 patients, 63%), and auditory (13 patients, 48%) findings. Initial rates of mild, moderate and severe vision loss were 19 eyes (35.2%), 12 eyes (22.2%), and 23 eyes (42.6%), respectively, compared with final rates of 19 eyes (35.2%), 14 eyes (25.6%) and 21 eyes (38.9%), respectively. Average change in visual acuity was 15 0.1 ± 6.3 Snellen lines. Rates of immunomodulatory therapy (IMT) use (10 patients, 37%) fell short of targets.Conclusions: VKH may cause potentially severe uveitis in this population. Comorbidities including tuberculosis and diabetes, in addition to unique cultural, linguistic and geographic factors, may necessitate complex, individualized management strategies.
