Limited efficacy of adalimumab in the acute phase of serpiginous choroiditis refractory to corticosteroid and cyclosporine, a case report

Long-Term Outcomes of Adalimumab Treatment in Conventional Treatment-Resistant Serpiginous Choroiditis

BACKGROUND/OBJECTIVES

To investigate the long-term efficacy and safety of adalimumab(ADA) in the treatment of patients with serpiginous choroiditis (SC) refractory to conventional therapy through quantitative parameters.

SUBJECTS/METHODS

A retrospective analysis was conducted on patients diagnosed with SC clinically and through fundus autofluorescence(FAF). Patients receiving ADA treatment were included. Demographic and clinical characteristics of the patients, association with tuberculosis (TB) infection, number of immunosuppressive therapies, recurrences, best corrected visual acuity (BCVA) change, and ADA-related side effects were recorded. The progression rate before and after ADA was calculated based on the area involved by FAF.

RESULTS

Sixteen eyes of 8 patients (3 female/5 male) were enrolled to the study. The median (IQR) age was 53.5 (16.5) years. Diagnosis was SC in 4, ampiginous choroiditis in 3, and TB-related serpiginous-like choroiditis in 1 patient. Peripapillary involvement was present in 10 of 16 eyes. The area involved by FAF continued to progress under ADA treatment, however the progression rate was decreased (p = 0.143).The BCVA was preserved (p = 0.772). The number of systemic and local treatments decreased with ADA (p = 0.025 and 0.019, respectively). Additionally, the number of recurrences was reduced with ADA (p = 0.002). Median (IQR) follow-up was 45(28.75) months. Two patients experienced ADA-related side effects (pulmonary TBand rash).

CONCLUSIONS

Our findings suggest a promising role for ADA in halting the progression of SC and have implications for improving outcomes. Despite the evidence in the literature at the level of case reports, ADA can be used effectively with close monitoring for potential risks.

Mechanisms, Pathophysiology and Current Immunomodulatory/Immunosuppressive Therapy of Non-Infectious and/or Immune-Mediated Choroiditis

Non-infectious choroiditis comprises immune-mediated diseases resulting from diverse pathophysiological mechanisms. These conditions are sub-divided into two main groups, (1) diseases of the choriocapillaris and (2) diseases of the choroidal stroma. The purpose of this study is to expose the pathophysiology of the most common diseases of both these groups and recommend the optimal immunomodulatory/immunosuppressive therapy of each analyzed condition based on literature data and data from our own centers. Material and Methods: Narrative review. In the group of choriocapillaritis entities or primary inflammatory choriocapillaropathies (PICCPs) including multiple evanescent white dot syndrome (MEWDS), acute posterior multifocal placoid pigment epitheliopathy (APMPPE), idiopathic multifocal choroiditis (MFC) and serpiginous choroiditis (SC), as well as secondary choriocapillaritides including acute syphilitic posterior multifocal placoid chorioretinitis (ASPMPC) and tuberculosis-related SC (TB-SC), were analyzed. In the group of stromal choroidites, HLA-A29 birdshot retinochoroiditis (BRC) and Vogt-Koyanagi-Harada (VKH) disease were included. For each entity a literature search, in the PubMed database, on treatment was performed and analyzed and the therapeutic attitudes of our own centers were presented. Management of immune-mediated choroiditis implies vigorous immunosuppressive therapy given in a prompt and prolonged fashion in most of these entities.

Serpiginous Choroiditis Presenting in Association With Clostridium difficile Infection and Ulcerative Colitis

Purpose:

This work reports a case of serpiginous choroiditis (SC) in association with ulcerative colitis and Clostridium difficile infection.

Methods:

A case report is discussed.

Results:

A 35-year-old man with a history of ulcerative colitis and recently treated C difficile infection presented with a rapid decline in central visual acuity in both eyes. Examination findings included geographic creamy-white lesions extending from the peripapillary region in both eyes. Multimodal imaging and negative infectious workup results supported the diagnosis of SC. Visual acuity and examination findings improved after initiation of systemic prednisone therapy. Adalimumab was initiated as a steroid-sparing treatment. At the last follow-up, 5 months after the initial presentation, SC and ulcerative colitis both remain in remission.

Conclusions:

SC has been previously described in patients with systemic disorders, including autoimmune conditions. This patient developed SC following C difficile infection and in the context of active ulcerative colitis. To our knowledge, this is the first report of SC in association with these entities.

The efficacy of adalimumab in treating patients with central multifocal choroiditis

PURPOSE

To evaluate the efficacy of adalimumab in patients with central multifocal choroiditis (cMFC) refractory to conventional corticosteroid-sparing immunomodulatory agents (IMT).

METHODS

Medical records were reviewed from all patients with cMFC and treated with adalimumab with follow-up of at least 12 months. The study focused on the 12 months prior to and after the start of adalimumab. The imaging results were independently evaluated by two ophthalmologists. The main outcomes were the number of patients without a relapse of disease activity in 12 months after the start of adalimumab and the ability to stop the systemic corticosteroids to evaluate the corticosteroid-sparing effect.

RESULTS

Twelve patients (18 eyes) were included. In 8/12 (67%) patients no relapse of disease activity was observed in the 12 months after the start of adalimumab. In 9/12 patients the systemic corticosteroid treatment could be stopped and in an additional 2 patients tapered to ≤7,5mg daily. In the 12 months before the start of adalimumab, the patients experienced a median of 3 (range 2-4) relapses of disease activity. Nine patients experienced relapses while treated with a combination of systemic corticosteroids (mean dose 13,6 mg; range 5-25 mg) and IMT. Moreover, 3 patients treated with IMT, experienced relapses after tapering and stopping the systemic corticosteroids. In all eyes (n = 5) with CNV before the start of adalimumab, the intravitreal anti-VEGF injections could be stopped after the start of adalimumab.

CONCLUSIONS

AND IMPORTANCE: Adalimumab may be effective in patients with cMFC refractory to IMT and may be considered as a treatment option in patients with cMFC.
