Bilateral cytomegalovirus retinitis in a patient with systemic lupus erythematosus

Bilateral Cytomegalovirus Retinitis in a Patient with Systemic Lupus Erythematosus

Purpose

The purpose of this study was to report the case of a patient who underwent vitrectomy for bilateral rhegmatogenous retinal detachment caused by cytomegalovirus (CMV) retinitis while undergoing steroid and immunosuppressant therapy for systemic lupus erythematosus (SLE).

Case Report

We report on a 29-year-old female who was undergoing steroids and immunosuppressants treatment for SLE at Osaka Medical College Hospital, Takatsuki City, Japan. Examination of the patient due to prolonged and worsening diarrhea revealed positive test results for C7-HRP, and she was diagnosed with CMV colitis. She was subsequently admitted to the hospital and started on intravenous ganciclovir for treatment. Approximately 1.5 months later, her primary complaint was deterioration of the upper visual field in her left eye, and she was then referred to the Department of Ophthalmology. Numerous granular exudative spots were found around the lower retinal area of her left eye with retinal breaks that had developed in an area of retinal necrosis that resulted in retinal detachment. After time was allowed for the patient's general condition to improve, a vitrectomy was performed on that eye. The patient subsequently developed a similar retinal detachment in her right eye, for which she underwent a vitrectomy. Although the patient required multiple surgeries on both eyes, her retinas currently remain reattached and the inflammation has subsided.

Conclusion

The findings of this study show that strict attention must be paid to SLE patients on immunosuppressive therapy due to the possible association of CMV retinitis.

Cytomegalovirus retinitis in a seronegative patient with systemic lupus erythematosus on immunosuppressive therapy

Aim

The purpose of this study is to report a rare case of cytomegalovirus (CMV) retinitis in a seronegative patient with systemic lupus erythematosus (SLE) on immunosuppressive therapy.

Methods

A seronegative patient with SLE who was on immunosuppressive therapy developed CMV retinitis. The immunosuppressive therapy was tapered, and the patient was given intravitreal ganciclovir and foscarnet in addition to systemic ganciclovir. The follow-up visits were documented.

Result

The patient responded to the treatment and there was complete resolution.

Conclusion

CMV retinitis is a rapidly progressive condition and patients on immunosuppressive therapy should be referred to an ophthalmologist for periodic check-up for early diagnosis and treatment of this devastating ophthalmic condition. For clinically resistant CMV retinitis in seronegative patients with SLE, a combination therapy of intravitreal foscarnet with oral and intravenous ganciclovir is useful.

Cytomegalovirus as a trigger for systemic lupus erythematosus

Cytomegalovirus (CMV) infections have been associated with exacerbations of systemic lupus erythematosus (SLE). Their role in triggering this disease, however, remains a subject of debate. We present a 43-year-old man with no history of systemic illness who developed persistent signs and symptoms of a CMV-associated mononucleosis-like syndrome while fulfilling diagnostic criteria for previously undiagnosed SLE. The patient was admitted with persistent fever for 3 weeks, cervical lymphadenopathy, elevated liver function tests, and leukopenia. Further laboratory studies revealed positive antinuclear antibody, anti-dsDNA, anti-Sm/RNP, rheumatoid factor, and anticardiolipin antibodies along with decreased complement levels and proteinuria of 876 mg/dL. CMV immunoglobulin M was positive in the absence of CMV immunoglobulin G, supporting acute CMV infection. Symptoms improved with intravenous administration of methylprednisolone and ganciclovir therapy. Mechanisms by which CMV may trigger autoimmunity have been proposed, and this case could support CMV infection as a potential trigger for SLE in susceptible individuals.

Acute viral infections in patients with systemic lupus erythematosus: description of 23 cases and review of the literature

Few studies have evaluated the impact of viral infections on the daily management of patients with systemic lupus erythematosus (SLE). We analyzed the etiology and clinical features of acute viral infections arising in patients with SLE and their influence on the diagnosis, prognosis, and treatment of SLE. Cases occurring within the last 5 years were selected from the databases of 3 large teaching hospitals. Acute viral infections were confirmed by the identification of specific antiviral IgM antibodies and subsequent seroconversion with detection of specific IgG antibodies. In autopsy studies, macroscopic findings suggestive of viral infection were confirmed by direct identification of the virus or viruses in tissue samples. We performed a MEDLINE search for additional cases reported between January 1985 and March 2008. We included 88 cases (23 from our clinics and 65 from the literature review) of acute viral infections in patients with SLE. Twenty-five patients were diagnosed with new-onset SLE (fulfillment of the 1997 SLE criteria) associated with infection by human parvovirus B19 (n = 15), cytomegalovirus (CMV; n = 6), Epstein-Barr virus (EBV; n = 3), and hepatitis A virus (n = 1). The remaining 63 cases of acute viral infections arose in patients already diagnosed with SLE: in 18 patients, symptoms related to infection mimicked a lupus flare, 36 patients, including 1 patient from the former group who presented with both conditions, presented organ-specific viral infections (mainly pneumonitis, colitis, retinitis, and hepatitis), and 10 patients presented a severe, multiorgan process similar to that described in catastrophic antiphospholipid syndrome-the final diagnosis was hemophagocytic syndrome in 5 cases and disseminated viral infection in 5. Twelve patients died due to infection caused by CMV (n = 5), herpes simplex virus (n = 4), EBV (n = 2), and varicella zoster virus (n = 1). Autopsies were performed in 9 patients and disclosed disseminated herpetic infection in 6 patients (caused by herpes simplex in 4 cases, varicella in 1, and CMV in 1) and hemophagocytic syndrome in 3. A higher frequency of renal failure (54% vs. 19%, p = 0.024), antiphospholipid syndrome (33% vs. 6%, p = 0.023), treatment with cyclophosphamide (82% vs. 37%, p = 0.008), and multisystemic involvement at presentation (58% vs. 8%, p < 0.001); and a lower frequency of antiviral therapy (18% vs. 76%, p < 0.001) were found in patients who died, compared with survivors. The most common viral infections in patients with SLE are parvovirus B19 (predominantly mimicking SLE presentation) and CMV (predominantly presenting in severely immunosuppressed patients). CMV infection may mimic a lupus flare or present with specific organ involvement such as gastrointestinal bleeding or pulmonary infiltrates. Other herpesviruses are common in immunosuppressed SLE patients and may produce a wide range of manifestations. Physicians should examine the pharynx, eyes, skin, and genitalia and should conduct serologic and molecular studies to improve early detection of viral infection in patients with SLE.

Cytomegalovirus retinitis in a patient with dermatomyositis

Cytomegalovirus (CMV) retinitis rarely occurs in patients with connective tissue disease. We present a rare case of CMV retinitis in a patient with dermatomyositis. A 38-year-old man was admitted due to blurred vision and floaters of right eye. He had been diagnosed with dermatomyositis and taken prednisolone and immunosuppressive agents for 10 months. He was diagnosed as having CMV retinitis based upon ophthalmologic examination, decreased CD4+T cell count, and positive IgM anti-CMV antibody. Intravenous ganciclovir was administrated with cessation of immunosuppressive agents for 40 days and the lesion did not progress. This is the first report of a CMV retinitis that developed in a patient with dermatomyositis.

Bilateral cytomegalovirus retinitis in a patient with systemic lupus erythematosus and end-stage renal disease

Rheumatic diseases are not commonly associated with cytomegalovirus (CMV) retinitis. We report a case of bilateral CMV retinitis in a human immunodeficiency virus-seronegative patient with systemic lupus erythematosus (SLE) who was undergoing hemodialysis for end-stage renal disease. The CMV retinitis in this patient was associated with combined azathioprine and low-dose corticosteroid therapy for lupus flare. This association may have important clinical implications because this drug combination is used routinely to treat active SLE. Our patient responded to discontinuation of azathioprine, reduction of the corticosteroid dose, and systemic administration of ganciclovir. We recommend that clinicians maintain heightened awareness of the possibility of CMV retinitis in patients with SLE and end-stage renal disease who are receiving azathioprine and low-dose corticosteroids.
