Optic nerve and retinal features in uveitis associated with juvenile systemic granulomatous disease (Blau syndrome).

PURPOSE: To determine whether patients with juvenile systemic granulomatous disease (JSGD) (Blau syndrome) and uveitis have a characteristic ocular phenotype. METHODS: Clinical and imaging data were collected retrospectively from patients attending the Regional Combined Paediatric Rheumatology and Ocular Inflammatory Service, Bristol Eye Hospital. General demographic information, laterality of the uveitis, age at onset, anatomical classification and course of the uveitis, clinical phenotype and specific NOD2 mutation were recorded for each patient. RESULTS: Seventeen eyes from nine patients (five males; four females) were included in the study. Mean age at the disease onset was 15 months, range 1-84 months. Eight patients had bilateral uveitis. Anterior uveitis was present in five eyes, intermediate uveitis in two eyes, and there were 10 eyes with panuveitis, manifesting as multifocal choroiditis. Appearance of optic disc included indistinct disc margins in six eyes, optic nerve head pallor in six eyes, optic disc vessel sheathing in four eyes, and there was peripapillary hypo/hyperpigmentation in 13 eyes accompanied with characteristic peripapillary nodular excrescences. Among NOD2 mutations, the p.R334W was the most commonly detected (n: four cases), and three patients carried novel variants, the p.E338D and p.D390V variants in one patient, and the p.H520Y and p.Q809K variants in two different patients. CONCLUSIONS: Chronic bilateral panuveitis and a nodular peripapillary appearance in childhood onset uveitis are characteristic features of JSGD, which support the need for an appropriate genetic NOD2 analysis.

The safety and efficacy of noncorticosteroid triple immunosuppressive therapy in the treatment of refractory chronic noninfectious uveitis in childhood.

OBJECTIVE: To assess the safety and efficacy of noncorticosteroid triple immunosuppressive therapy in the treatment of refractory chronic noninfectious childhood uveitis. METHODS: Subjects were retrospectively selected from a database. Patients were included if they were diagnosed with chronic, noninfectious uveitis at 16 years of age or under and treated with triple immunosuppressive therapy for at least 6 months (following failure of a combination of 2 immunosuppressants). Patient demographics, diagnoses, duration of uveitis, drug dosages, active joint inflammation, and ophthalmologic data were recorded. Efficacy outcomes for triple therapy were recorded at 6 months. RESULTS: Thirteen patients with bilateral uveitis were included. Using Standardized Uveitis Nomenclature (SUN) criteria, at 6 months only 11 eyes (42%) had a 2-step improvement in anterior chamber cell inflammation (n = 26). In addition, 2 patients required additional oral corticosteroid treatment. There were 4 significant infectious adverse events during a total of 21.9 patient-years (PY) on triple therapy (0.18 events per PY). CONCLUSION: In this group of children with refractory uveitis, addition of a third immunosuppressive agent did not confer substantial benefit in redressing ocular inflammation and was associated with significant infections in a minority of patients.

Use of adalimumab in refractory non-infectious childhood chronic uveitis: efficacy in ocular disease--a case cohort interventional study.

OBJECTIVE: To assess the use of adalimumab in the treatment of refractory non-infectious childhood chronic uveitis. METHODS: A case cohort interventional study was performed on patients with uveitis, who were treated with adalimumab after failure of treatment with a combination of corticosteroids and another immunosuppressant drug. Main outcome measures were (i) stability of vision, (ii) stability of inflammation and (iii) reduction of immunosuppressive load. Adverse events and reasons for stopping adalimumab were noted. RESULTS: Seventeen patients from a single regional centre were included in the study. Nine patients had previously received an anti-TNF agent, and because of inefficacy, all were changed to adalimumab. At 12 months, fewer patients had visual acuity worse than LogMAR 0.4 (18% vs 32% at baseline). Using standardized uveitis nomenclature criteria, at 3 months, 50% of the patients eyes (n = 32) had improved, 16% had stable inflammation and 3% had worsened, whereas 31% were maintained with no anterior chamber cells. Six patients required courses of oral steroids for uveitis. Seven patients received intra- or periocular injections of steroids. Adalimumab treatment was interrupted in one patient because of varicella zoster infection. It was stopped in three patients. Seven (41%) patients reported injection site reactions. CONCLUSION: In this group of children with refractory uveitis, use of adalimumab was associated with improvement in visual acuity and improving or stable ocular inflammation. However, it did not completely obviate the need for systemic or periocular steroid treatment. Prospective randomized controlled trials are required to help determine which subset of patients may benefit from adalimumab and the duration of treatment.
