Severe scleritis and urticarial lesions

Systemic Vasculitis and Its Association with the Eye

Vasculitis is a group of diseases characterized by the inflammation of the blood vessel walls. They are classified according to the size of the main vessel involved: large vessel, medium vessel, and small vessel vasculitis. Ophthalmic manifestations are quite common in most of these diseases. Episcleritis and scleritis are the most prevalent manifestation of vasculitis. However, there are certain ocular features characteristic of specific vasculitis entities. Given the severity and potential life-threat of these diseases, knowledge of the ocular manifestations is mandatory for the ophthalmologists.

Hypocomplementemic urticarial vasculitis syndrome presenting with bilateral scleritis

Hypocomplementemic urticarial vasculitis syndrome (HUVS) is a rare autoimmune disorder characterised by recurrent urticarial lesions and acquired hypocomplementemia with systemic manifestations. The authors present the case of a 70-year-old man who presented to the ophthalmology clinic with bilateral scleritis and ocular hypertension. He was diagnosed with HUVS after a 6-month period of bilateral scleritis, vestibulitis, significant weight loss, mononeuritis multiplex and recurrent urticarial vasculitis with pronounced persistent hypocomplementemia and the presence of anti-C1q antibodies. Disease control was eventually obtained with mycophenolate and prednisolone.

Urticarial lesions: if not urticaria, what else? The differential diagnosis of urticaria: part II. Systemic diseases

There are a number of systemic disorders that can manifest with urticarial skin lesions, including urticarial vasculitis, connective tissue diseases, hematologic diseases, and autoinflammatory syndromes. All of these conditions may enter into the differential diagnosis of ordinary urticaria. In contrast to urticaria, urticarial syndromes may manifest with skin lesions other than wheals, such as papules, necrosis, vesicles, and hemorrhages. Lesions may have a bilateral and symmetrical distribution; individual lesions have a long duration, and their resolution frequently leaves marks, such as hyperpigmentation or bruising. Moreover, systemic symptoms, such as fever, asthenia, and arthralgia, may be present. The most important differential diagnosis in this group is urticarial vasculitis, which is a small-vessel vasculitis with predominant cutaneous involvement. Systemic involvement in urticarial vasculitis affects multiple organs (mainly joints, the lungs, and the kidneys) and is more frequent and more severe in patients with hypocomplementemia. Clinicopathologic correlation is essential to establishing a correct diagnosis.

LEARNING OBJECTIVES

After completing the learning activity, participants should be able to distinguish urticarial lesions suggesting diagnoses other than common urticaria; assess patients with urticarial lesions, and suspect systemic diseases presenting with urticarial skin lesions.

Scleritis and systemic disease association in a community-based referral practice

PURPOSE

To evaluate the association between scleritis and systemic disease in a non-university, non-tertiary referral practice and to describe our experience with scleritis treatment.

DESIGN

Retrospective chart review.

METHODS

The medical records of patients with scleritis between 2001 and 2007 were reviewed for associated systemic disease.

RESULTS

In our series of 86 patients with scleritis, 55 patients (64.0%) had isolated scleritis while 31 patients (36.0%) had associated systemic-disease. Twenty-six patients (83.9%) with systemic disease had diagnosed systemic disease at the time of initial scleritis presentation, while 5 patients (16.1%) were diagnosed following systemic work-up. Those diagnosed after systemic work-up were more likely to have systemic vasculitic disease as opposed to a rheumatic or infectious disease. Patients with and without associated systemic disease were likely to require systemic therapy at similar rates (93.5% and 92.7%, respectively). Five patients with steroid-refractory scleritis were treated with infliximab (Remicade; Centocor Inc, Horsham, Pennsylvania, USA) and all responded without evidence of adverse effect. Seven patients were treated with mycophenolate mofetil (CellCept; Roche Laboratories, Nutley, New Jersey, USA), of which three improved.

CONCLUSIONS

The association between scleritis and systemic disease in a community-based referral practice may be lower than in tertiary referral or university-based centers. Although thorough systemic disease evaluation is warranted in scleritis patients, most patients with associated systemic disease will have such a diagnosis prior to the development of scleritis. The need to institute aggressive systemic therapy cannot be predicted by the presence of an associated systemic disease. Infliximab and mycophenolate mofetil are useful additions to the scleritis practitioner's armamentarium for steroid-refractory scleritis.

Recurrent Optic Disc and Retinal Vasculitis in a Patient with Drug-Induced Urticarial Vasculitis

The purpose of this study was to report recurrent optic disc and retinal vasculitis in a patient with drug-induced urticarial vasculitis. Complete ophthalmological examination including fluorescein angiography and visual field examination were done. A 53-year-old woman with recurrent painful urticarial skin lesions following trimethoprim sulfamethoxazole usage had the clinical and histopathological diagnosis of urticarial vasculitis. Two years after cutaneous manifestations, she began to notice visual disturbances in both eyes that recurred at 1-year intervals. Her ophthalmological findings were consistent with recurrent vasculitis of the optic nerve and retina. Treatment with high-dose corticosteroids and hydroxychloroquine resulted in the resolution of cutaneous and ocular manifestations. This patient demonstrates that recurrent occlusive vasculitis of the optic nerve and retina can occur in this rare disease. These patients should be examined periodically by ophthalmologists.

Scleritis and peripheral ulcerative keratitis

Scleritis and peripheral ulcerative keratitis (PUK) can present as isolated conditions or as part of a systemic inflammatory or infectious disorder. Both are serious ocular conditions that can result in vision loss and require early diagnosis and treatment. Nearly two thirds of patients with non-infectious scleritis require systemic glucocorticoid therapy and one fourth need a glucocorticoid-sparing agent as well. Essentially all patients with non-infectious PUK require systemic glucocorticoids. A detailed clinical history, thorough physical examination, and thoughtful laboratory evaluations are important in the exclusion of underlying disorders and extraocular involvement.

Mycophenolate Mofetil Therapy for Inflammatory Eye Disease

PURPOSE

To evaluate treatment outcomes with mycophenolate mofetil in patients with inflammatory eye disease.

DESIGN

Retrospective case series.

PARTICIPANTS

Eighty-four consecutive patients with inflammatory eye disease treated with mycophenolate mofetil at an academic referral center.

METHODS

Medical records were reviewed for treatment with mycophenolate mofetil. Dose of mycophenolate mofetil, response to therapy, dose of prednisone, use of other immunosuppressive drugs, and side effects associated with the use of mycophenolate mofetil were recorded.

MAIN OUTCOME MEASURES

Ability to control ocular inflammation with mycophenolate mofetil and to taper prednisone to < or =10 mg daily, and incidence of treatment-related side effects.

RESULTS

Of the 84 patients treated with mycophenolate mofetil, 61% had uveitis, 17% had scleritis, 11% had mucous membrane pemphigoid, and 11% had orbital or other inflammatory disease. Forty-three percent of patients treated with mycophenolate mofetil had been treated with at least one other immunosuppressive drug previously. The median dose of prednisone at the start of mycophenolate mofetil therapy was 40 mg, and 82% of the patients were considered a treatment success, as judged by the ability to control the inflammation and taper prednisone to < or =10 mg daily. Median time to treatment success was 3.5 months. Mycophenolate mofetil therapy was discontinued due to insufficient efficacy at a rate of 0.10 per person-year (PY) and due to side effects at a rate of 0.08/PY. The most frequent side effect was gastrointestinal upset, with a rate of 0.19/PY.

CONCLUSIONS

These data suggest that mycophenolate mofetil may be an effective corticosteroid-sparing agent in the treatment of inflammatory eye disease with a manageable side effect profile.
