Objective: In a large series of White patients with refractory uveitis due to Behçet disease (BD) being treated with infliximab (IFX), we assessed (1) long-term efficacy and safety of IFX, and (2) IFX optimization when ocular remission was achieved.Methods: Our multicenter study of IFX-treated patients with BD uveitis refractory to conventional immunosuppressant agents treated 103 patients/185 affected eyes with IFX as first biologic therapy in the following intervals: 3–5 mg/kg intravenous at 0, 2, 6, and then every 4–8 weeks. The main outcome variables were analyzed at baseline, first week, first month, sixth month, first year, and second year of IFX therapy. After remission, based on a shared decision between patient and clinician, IFX optimization was performed. Efficacy, safety, and cost of IFX therapy were evaluated.Results: In the whole series (n = 103), main outcome variables showed a rapid and maintained improvement, reaching remission in 78 patients after a mean IFX duration of 31.5 months. Serious adverse events were observed in 9 patients: infusion reactions (n = 4), tuberculosis (n = 1),Mycobacterium aviumpneumonia (n = 1), severe oral ulcers (n = 1), palmoplantar psoriasis (n = 1), and colon carcinoma (n = 1). In the optimization subanalysis, the comparative study between optimized and nonoptimized groups showed (1) no differences in clinical characteristics at baseline, (2) similar maintained improvement in most ocular outcomes, (3) lower severe adverse events, and (4) lower mean IFX costs in the optimized group (€4826.52 vs €9854.13 per patient/yr).Conclusion: IFX seems to be effective and relatively safe in White patients with refractory BD uveitis. IFX optimization is effective, safe, and cost-effective.

Blau syndrome (BS) is an autoinflammatory disorder characterized by non-caseating granulomatous dermatitis, arthritis, and uveitis. We present a case of refractory and severe BS that was treated with the Janus kinase inhibitors (JAKINIBS), Tofacitinib (TOFA) and then Baricitinib (BARI). Our aim was to describe the clinical and immunological outcomes after treatment with JAKINIBS. Blood tests and serum samples were obtained during follow-up with TOFA and BARI. We assessed their effects on clinical outcomes, acute phase reactants, absolute lymphocyte counts (ALCs), lymphocyte subset counts, immunoglobulins, and cytokine levels. A review of the literature on the use of JAKINIBS for the treatment of uveitis and sarcoidosis was also conducted. TOFA led to a rapid and maintained disease control and a steroid-sparing effect. A decrease from baseline was observed in ALC, CD3+, CD4+, CD8+, and natural killer (NK) cell counts. B-cells were stable. Serum levels of interleukin (IL)-4 and tumor necrosis factor alpha (TNF-α) increased, whereas IL-2, IL-6, IL-10, and IL-17 maintained stable. TOFA was discontinued after 19 months due to significant lymphopenia. The initiation of BARI allowed maintaining adequate control of disease activity with an adequate safety profile. The literature review showed seven patients with uveitis and five with sarcoidosis treated with JAKINIBS. No cases of BS treated with JAKINIBS were found. We report the successful use of JAKINIBS in a patient with refractory and severe BS.

Objectives To evaluate effectiveness and safety of certolizumab pegol (CZP) in uveitis due to immune-mediated inflammatory diseases (IMID). Methods Multicentre study of CZP-treated patients with IMID uveitis refractory to conventional immunosuppressant. Effectiveness was assessed through the following ocular parameters: best-corrected visual acuity, anterior chamber cells, vitritis, macular thickness and retinal vasculitis. These variables were compared between the baseline, and first week, first, third, sixth months, first and second year. Results We studied 80 (33 men/47 women) patients (111 affected eyes) with a mean age of 41.6±11.7 years. The IMID included were: spondyloarthritis (n=43), Behçet’s disease (n=10), psoriatic arthritis (n=8), Crohn’s disease (n=4), sarcoidosis (n=2), juvenile idiopathic arthritis (n=1), reactive arthritis (n=1), rheumatoid arthritis (n=1), relapsing polychondritis (n=1), Conclusions CZP seems to be effective and safe in uveitis related to different IMID, even in patients refractory to previous biological drugs.

Background: The leading cause of blindness due to non-infectious uveitis is cystoid macular edema (CME). Behçet’s disease (BD) is one of the most commonly conditions related to CME. Objectives: To compare the effectiveness and safety of adalimumab (ADA), infliximab (IFX) and certolizumab (CZP) in refractory CME due to BD. Methods: Multicenter study of BD-CME patients with no response to glucocorticoids (GCs) and at least one conventional immunosuppressive drug. At baseline, all patients presented CME, defined by OCT > 300 µ. The effectiveness of ADA, IFX and CZP was assessed over a 2-year period from baseline using the following ocular parameters: macular thickness (µm), visual acuity (BCVA), anterior chamber (AC) cells and vitritis. Mixed-effects regression models were applied. Results: a total of 50 patients (75 eyes) were studied (ADA = 25; IFX = 15 and CZP = 10). No significant differences in demographic parameters were found among the three groups. However, individuals in the CZP group had a significantly extended time from diagnosis to treatment onset (72 (36–120) months, p = 0.03) and had received a higher number of biological therapies (1.7 ± 1.1) compared to the ADA and IFX groups. Within the CZP group, ADA and IFX were previously administrated in seven patients. After 2 years of follow-up, a rapid and sustained reduction in macular thickness was noted in all three groups with no significant differences between them. Additionally, enhancements in BCVA, AC cells and vitritis were also observed. No serious adverse events were reported in the CZP group, although one isolated case of bacteremia was documented in the ADA group. ADA, IFX and CZP appear to be effective and safe treatments for refractory CME in BD. CZP seems to remain effective even in patients with an insufficient response to ADA and/or IFX. Conclusions: ADA, IFX and CZP appear to be effective and safe treatments for refractory CME in BD. CZP seems to remain effective even in patients with an insufficient response to ADA and/or IFX.

We aimed to assess the efficacy of biologic therapy in refractory non-Multiple Sclerosis (MS) Optic Neuritis (ON), a condition more infrequent, chronic and severe than MS ON. This was an open-label multicenter study of patients with non-MS ON refractory to systemic corticosteroids and at least one conventional immunosuppressive drug. The main outcomes were Best Corrected Visual Acuity (BCVA) and both Macular Thickness (MT) and Retinal Nerve Fiber Layer (RNFL) using Optical Coherence Tomography (OCT). These outcome variables were assessed at baseline, 1 week, and 1, 3, 6 and 12 months after biologic therapy initiation. Remission was defined as the absence of ON symptoms and signs that lasted longer than 24 h, with or without an associated new lesion on magnetic resonance imaging with gadolinium contrast agents for at least 3 months. We studied 19 patients (11 women/8 men; mean age, 34.8 ± 13.9 years). The underlying diseases were Bechet’s disease (n = 5), neuromyelitis optica (n = 3), systemic lupus erythematosus (n = 2), sarcoidosis (n = 1), relapsing polychondritis (n = 1) and anti-neutrophil cytoplasmic antibody -associated vasculitis (n = 1). It was idiopathic in 6 patients. The first biologic agent used in each patient was: adalimumab (n = 6), rituximab (n = 6), infliximab (n = 5) and tocilizumab (n = 2). A second immunosuppressive drug was simultaneously used in 11 patients: methotrexate (n = 11), azathioprine (n = 2), mycophenolate mofetil (n = 1) and hydroxychloroquine (n = 1). Improvement of the main outcomes was observed after 1 year of therapy when compared with baseline data: mean ± SD BCVA (0.8 ± 0.3 LogMAR vs. 0.6 ± 0.3 LogMAR; p = 0.03), mean ± SD RNFL (190.5 ± 175.4 μm vs. 183.4 ± 139.5 μm; p = 0.02), mean ± SD MT (270.7 ± 23.2 μm vs. 369.6 ± 137.4 μm; p = 0.03). Besides, the median (IQR) prednisone-dose was also reduced from 40 (10–61.5) mg/day at baseline to. 2.5 (0–5) mg/day after one year of follow-up; p = 0.001. After a mean ± SD follow-up of 35 months, 15 patients (78.9%) achieved ocular remission, and 2 (10.5%) experienced severe adverse events. Biologic therapy is effective in patients with refractory non-MS ON.
