   Abstract 


Ocular involvement in pemphigus vulgaris (PV) is relatively rare. The conjunctiva and eyelids are considered the most common affected sites in ocular pemphigus. Scleritis is rarely reported as a manifestation of PV. We present a case report of anterior scleritis as a manifestation of PV and its response to rituximab therapy.

   Introduction Top


Pemphigus vulgaris (PV) is a rare, severe immune-mediated mucocutaneous disease. It is characterized by autoantibody production against intercellular adhesion molecules which results in loss of keratinocytes adhesions, mainly circulating IgG antibodies against desmoglein 3 or both desmoglein 1 and desmoglein 3.[1],[2] These molecules are members of the cadherins family, a cell adhesion molecule that binds epithelial cells to each other. Clinically, the loss of keratinocyte to keratinocyte adhesion will lead to painful erosions and blisters of the skin and mucous membranes including oral, nasopharyngeal, conjunctival, anal, and genital mucosae.[3],[4] Akhyani et al. reported an estimated ocular involvement of PV to be around 16.5% with conjunctivitis being the most common manifestation followed by erosion of the palpebral conjunctiva.[5]


   Case Report Top


A 45-year-old female, who is a known to have PV for the last 5 years, presented to the dermatology clinic with a 8-day history of redness of her right eye. The patient has been following for a recalcitrant PV, confirmed by histopathological studies and direct immunofluorescence, involving her oral, pharyngeal, and laryngeal mucosae, for which she received multiple therapies with varying success including systemic corticotherapy, azathioprine, and mycophenolate mofetil. One week before this presentation, the patient received the first dose of 1 g of intravenous rituximab due to persistent disease despite immunosuppression. Dermatological examination revealed multiple erosions on the buccal mucosa, soft palate, and upper and lower gingivae. Ophthalmic examination revealed visual acuity of 20/20 in both eyes with normal intraocular pressures. The left eye examination was unremarkable. The right eye showed severe diffuse redness with dilation of deep episcleral vessels associated with tenderness to palpation [Figure 1]. There was no discharge, follicles, or papillae on the palpebral conjunctiva. The cornea was clear with a quiet anterior chamber. The posterior segment was normal. The patient was thought to have a diffuse anterior nonnecrotizing scleritis secondary to PV and topical prednisolone acetate 1% drops were given. Besides, she received the second dose of rituximab. Two weeks later, her oral and ocular lesions completely regressed with no recurrence until last follow-up 2 years after treatment.

   Discussion Top


Mucosal membranes are affected in the vast majority of patients with PV, with the oral cavity being the most common site affected and may represent the initial site of the disease.[6]

Ocular involvement in PV is considered rare.[1] However, there is no sufficient data estimating the prevalence of ocular involvement and the distinct clinical types in PV. In prospective, cross-sectional study on Iranian patients, 103 PV patients were designed to determine the prevalence, clinical types, and epidemiological trends of ocular involvement. Ocular involvement was present in 17 (16.5%) patients. Moreover, conjunctivitis was the most predominant type of ocular involvement (9/17, 52.9%), followed by erosion of the palpebral conjunctiva (7/17, 41.2%). Erosion of the bulbar conjunctiva was notable in only one patient (5.9%). The most frequently described symptoms were eye irritation (76.5%) and redness (76.5%).[5]

Scleritis is rarely reported in concurrence with PV. To the best of our knowledge, there are only a few reports describing the occurrence of scleritis during the course of PV.[7] Similar to our case, the reported case had a recalcitrant PV and persistent oral erosion and developed diffuse anterior nonnecrotizing scleritis only a few weeks after receiving rituximab therapy. The patient responded to oral indomethacin and prednisolone. In our case, the scleritis improved after the second dose of rituximab and prednisolone acetate eye drops.

The improvement in her ocular symptoms after the second dose of rituximab was concomitant with overall improvement of her pemphigus disease, which suggests that the scleritis is less likely a manifestation of PV. However, since both cases developed after rituximab therapy for PV, the role of rituximab in the development of scleritis cannot be ruled out. Although, up to our knowledge, there are no previous reports of scleritis induced by rituximab.

In conclusion, we present a case of diffuse anterior nonnecrotizing scleritis in concurrence with PV. Recognizing this association will hopefully guide ongoing immunosuppressive therapy.
