Abstract

Aim

Infliximab, an anti-tumor necrosis factor (TNF)-α monoclonal antibody, has been reported to be effective in refractory uveoretinitis in Behçet's disease. Because it has been used clinically for a short time, information on its adverse effects is limited. We report a patient who developed cystoid macular edema (CME) following infliximab use for uveoretinitis associated with Behçet's disease. Case Report: A 27-year-old man had refractory uveoretinitis and neuro-Behçet's disease, and intravenous infliximab was administered.

Results

One day after infliximab infusion, the patient complained of a decrease in the vision in his left eye. The visual acuity had decreased from 1.2 to 0.5. Daily optical coherence tomographic evaluations showed a progressive worsening of the CME, and fluorescein angiography showed a typical staining with a cystic pattern. Two weeks later, the height of CME appeared to reach a maximum level and thereafter gradually resolved in spite of the continuation of infliximab administration. The visual acuity improved while the patient was treated with repeated subtenon injections of steroids in addition to continuation of infliximab and finally increased from 0.15 to 1.2.

Conclusions

Although the mechanism of CME is not known, clinicians should be aware that infliximab therapy might cause a development and worsening of CME. Thus, it is crucial to rule out preexisting abnormalities in the macula prior to commencing infliximab infusion.

Adverse events after intravitreal infliximab (Remicade).

N Lemanski, Jerome Schartman, Matthew C. T. Hartman … (2009)

To determine the tolerability of intravitreal infliximab (Remicade) in patients with refractory diabetic macular edema or choroidal neovascularization secondary to age-related macular degeneration. This is a prospective, interventional, noncomparative, open-label, 12-week pilot study of intravitreal infliximab in four patients who failed conventional therapies. Two had diabetic macular edema and two had choroidal neovascularization secondary to age-related macular degeneration. All patients received 0.5 mg/0.05 mL intravitreal infliximab and were eligible for a second injection at 6 weeks if reinjection criteria were met. Outcome measures were best-corrected visual acuity using standard Early Treatment Diabetic Retinopathy Study refraction, central retinal thickness on optical coherence tomography, fluorescein angiography, standard electroretinography, and microperimetry. Patients were evaluated at Days 0 and 1 and Weeks 2, 6, and 12. Six months after study completion, all patients were tested for human antimouse and human antichimeric antibodies. At Week 12, visual acuity scores had declined in three patients. All patients had persistence of cystoid macular edema on optical coherence tomography, although two had a decrease in central retinal thickness. Three patients had an overall worsened appearance on angiography. On the final electroretinography, all patients had a decrease in maximal combined responses, from 7% to 24% from baseline, which may have been within expected variability of electroretinography data. To photopic flicker stimulus, three patients had slower latency of response, and all had decreased amplitudes. All patients declined on microperimetry. The first patient entered in the study met the criteria for a second injection because of improved standard electroretinography and microperimetry at Week 6. However, 2 weeks after the second injection, he developed panuveitis. Two other patients, after one injection only, had evidence of inflammation (vitritis or panuveitis) on examination at Week 6. Three patients developed systemic antibodies against infliximab (human antichimeric antibodies). Low-dose intravitreal infliximab was not well tolerated in this small group of patients and was both immunogenic and probably retinotoxic.

Infliximab effects compared to conventional therapy in the management of retinal vasculitis in Behçet disease.

Khalid F Tabbara, Amal Al-Hemidan (2008)

To assess the outcome of retinal vasculitis in patients with Behçet disease treated with infliximab compared to treatment with conventional therapy. Nonrandomized, retrospective comparative clinical study. Patients with Behçet disease with all four major criteria were included in this study. Patients had recurrent episodes of uveitis and retinal vasculitis. Thirty-three patients (Group 1) were treated with oral prednisone, cyclosporine, and azathioprine or methotrexate for a minimum period of three months. Ten patients (Group 2) who failed to respond to conventional therapy were given infliximab at a dose of 5 mg/kg in a single intravenous infusion on day 1 and every two weeks for a total of six doses. Patients were given the same treatment during each subsequent relapse. The main outcome measures were the number of relapses, visual outcome, and ocular complications. The mean follow-up period was 36 months in Group 1 and 30 months in Group 2. The mean number of relapses was significantly reduced and the duration of remission was longer in the infliximab therapy group compared to conventional therapy group (P < .0001). The visual acuity at 24 months follow-up was significantly better in patients treated with infliximab (Group 2) when compared to conventional therapy (Group 1) (P = .0059). Patients with Behçet disease had significant decrease in inflammation, improvement of visual acuity, and reduced ocular complications following infliximab when compared to conventional therapy. The number of relapses was less in the infliximab treatment group than the conventional therapy group.

Intravitreal administration of the anti-TNF monoclonal antibody infliximab in the rabbit.

Petros P. Sfikakis, Vasilios Liarakos, GEORGIOS D. AGROGIANNIS … (2009)

Tumor necrosis factor (TNF) is known to play an important role in various immune-mediated ocular diseases; intravenous administration of the anti-TNF monoclonal antibody infliximab has proved beneficial in such cases. Since intravitreal injection (when available) is a substitute for systemic administration of various drugs targeting the eye, we aimed to evaluate the safety of intravitreal injection of infliximab in the rabbit eye. Seven groups of New Zealand white rabbits (four animals in each group) received a single unilateral intravitreal injection (0.1 ml) of increasing doses of infliximab (namely 1, 2, 5, 8, 10 or 20 mg infliximab [Remicade]) or a sham injection respectively. Slit-lamp biomicroscopy, fundoscopy and electrophysiology recordings, i.e. scotopic, photopic and flicker responses, were performed at baseline and after 1, 5, 10, 15, 30 and 45 days. Infliximab-injected eyes were compared with sham-injected and with uninjected fellow eyes (n = 28). Animals were euthanized on day 45 for histopathological examination of the retinas. Clinical examination and electrophysiological testing were consistently unremarkable after either sham or 1 mg or 2 mg infliximab injections. In contrast, electrophysiological recordings were significantly reduced in a dose-dependent manner from day 1 through day 45, after 5, 8, 10 and 20 mg infliximab injections. Flicker responses were the most sensitive in detecting the lower toxic dose of 5 mg. Histopathological findings were similar in uninjected and sham-injected eyes, as well as after 1 mg or 2 mg infliximab injections. Consistent with the functional abnormalities, retinal deformities and diffuse edema were observed after injection of 5 mg or higher doses of infliximab. Intravitreal infliximab may be safely administered up to a dose of 2 mg in the rabbit eye. Such doses can be used in the design of future clinical trials assessing the effects of infliximab for selected patients with immune-mediated ocular conditions.
