Generalized cytomegalovirus infection in a patient with lupoid hepatitis

Unusual Manifestations of Acute Cytomegalovirus Infection in Solid Organ Transplant Hosts: A Report of Two Cases

Cytomegalovirus (CMV) infection is a common cause of morbidity and mortality in immunocompromised hosts. Tissue-invasive CMV disease causing ulcerative skin disease or esophageal necrosis is rare. We herein describe two cases: a 47-year-old renal and pancreas transplant recipient who presented with skin ulcerations on his elbow and a 50-year-old renal transplant recipient who presented with acute esophageal necrosis. In both, tissue biopsy revealed CMV inclusion bodies by immunohistochemical staining of infected endothelial and mucosal cells. Ganciclovir was given to both cases and full remission occurred. Due to the varying presentations of acute CMV infection in immunosuppressed hosts, high suspicion and early tissue biopsy are vital for proper diagnosis and treatment when any suspicious cutaneous or mucosal manifestations are present.

Viral diseases of the oral mucosa

A wide variety of both DNA and RNA viruses affect the oral cavity. When considered in conjunction with cutaneous features, careful examination of the oral mucosa and oropharynx aids the clinician in making a diagnosis. Examination of the oral cavity should be incorporated as a regular component of the dermatologic examination because diagnostic clues are readily available to assist in the evaluation of infectious processes.

Diagnosis and treatment of a case of cutaneous cytomegalovirus infection with a dramatic clinical presentation

A patient receiving long-term immunosuppressive treatment of systemic lupus erythematosus developed multiple large painful ulcers on her upper body. Histologic analysis showed cytopathic changes typical of cytomegalovirus infection that was confirmed by immunoperoxidase staining and polymerase chain reaction analyses. Treatment with ganciclovir and foscarnet resulted in clinical resolution. No recurrence was evident 6 months later.

Concurrent oral cytomegalovirus and herpes simplex virus infection in association with HIV infection. A case report

Recurrent oral herpes simplex virus lesions are common in both immunocompetent and immunocompromised persons. In contrast, cytomegalovirus-associated intraoral lesions are rarely seen, even in the immunocompromised host. We report a case of concurrent oral herpes simplex virus and cytomegalovirus infection, appearing as an ulcerative lesion of the labial mucosa in a patient with acquired immunodeficiency syndrome. Herpes simplex virus type 1 was shown to be present in the lesion by culture tests, histopathologic examination, immunohistochemistry findings and a direct immunofluorescence assay, and cytomegalovirus by histopathologic examination and immunohistochemistry findings. We deduce that the lesion was due to concurrent herpes simplex virus-1 and cytomegalovirus infection. The patient responded well to 2 weeks of treatment with a high dose of acyclovir.

Oral CMV lesions and the HIV infected. Early recognition can help prevent morbidity

Although they are rare, oral ulcers caused by cytomegalovirus infection can occur in immunocompromised people, including those infected with HIV. Once recognized, however, oral CMV lesions can be successfully treated in most cases. Moreover, early recognition permits prompt evaluation for CMV retinitis or disseminated CMV infection, and may help prevent morbidity caused by CMV.

Cytomegalovirus ulceration of the oropharynx

Cytomegalovirus (CMV) is a common opportunistic infection in both iatrogenic and HIV-induced immunosuppression. The usual sites of involvement are the gastro-intestinal tract, retina and lung. We present three cases of CMV ulceration of the oropharynx. All three patients presented with symptoms localized to the oropharynx and in each case the diagnosis was only made on histological examination of ulcer biopsy specimens. The patients all responded well to ganciclovir treatment and at writing none have required maintenance therapy (7-11 months post diagnosis).

Diagnosis of cutaneous cytomegalovirus infection: a review and report of a case

Cytomegalovirus infections are a major source of morbidity and mortality in immunocompromised patients. We report a case of cutaneous cytomegalovirus in a patient with the acquired immunodeficiency syndrome, in which routine light microscopy was suggestive but not diagnostic of cytomegalovirus. Immunohistochemical studies of the specimen for cytomegalovirus antigens revealed numerous intracytoplasmic and intranuclear viral inclusions. This case illustrates the utility of immunoperoxidase techniques to diagnose cytomegalovirus infection of the skin rapidly. Immunohistochemistry, DNA in situ hybridization, and polymerase chain reaction have been added to the more routine methods of viral culture and light microscopy to diagnose cytomegalovirus. In this report we review the cases of cutaneous cytomegalovirus in the literature and the laboratory detection methods available to establish this diagnosis.

Successful treatment of disseminated cutaneous cytomegalic inclusion disease associated with Hodgkin's disease

A case of disseminated cutaneous cytomegalic inclusion disease associated with Hodgkin's disease is described. The patient had a diffuse eruption of pruritic, erosive erythematous nodules. Histologically, many inclusion bodies were observed in perivascular areas of the skin lesions. Immunohistologically, the inclusion bodies positively stained with both anticytomegalovirus antibody and anti-factor VIII-related antibody. On electron microscopy many virus particles and dense bodies were found in the area where inclusion bodies were observed. Treatment with high-dose intravenous acyclovir and a large amount of immunoglobulin resulted in prompt healing of the skin lesions. Subsequently, the patient's Hodgkin's disease was well controlled on chemotherapy. The patient steadily improved without relapse of skin lesions 1 year after antiviral therapy was administered.

Long-term maintenance therapy with azathioprine in systemic lupus erythematosus

One hundred ten patients with systemic lupus erythematosus (SLE) were classified into two groups, patients with central nervous system (CNS) or severe renal disease (usually associated with a poor prognosis) and patients without these manifestations, to define criteria for azathioprine therapy. Fifty-four of 68 patients with a poor prognosis received azathioprine. Azathioprine-treated patients showed improved long-term survival (72% vs 29%, P less than .005) and fewer hospitalizations (0.24/patient-years vs 0.89/patient-years, P less than .001). Azathioprine therapy in 19 of 42 patients with a good prognosis was associated with fewer hospitalizations (.02/patient-years vs .17/patient-years, P less than .05), but no decrease in maintenace prednisone requirement. Progression from a good to a poor prognosis was less frequent (1 of 20 vs 11 of 34, P = less than .05) among azathioprine-treated patients. Toxicity of azathioprine was minimal. Azathioprine therapy is indicated in patients with CNS or severe renal disease, and in patients whose prognosis was good with frequent hospitalizations or a maintenance prednisone requirement greater than 15 mg/day.
