| Abstract: |
Herpes simplex virus (HSV) and cytomegalovirus (CMV) infections are commonly seen in immunocompromised patients, particularly in patients with HIV. However, fulminant CMV infection and concurrent infection with HSV and CMV in non-HIV patients are quite rare. We present the case of a 72-year-old HIV-negative man with a history of oropharyngeal carcinoma in remission and recent treatment of immune thrombocytopenic purpura with high-dose steroids who was transferred from an outside hospital for Ear Nose and Throat (END evaluation of a non-healing buccal ulcer. During initial presentation, the patient was found to be febrile with acute hypoxic respiratory failure and a chest x-ray suggestive of bacterial pneumonia, though he failed to improve with broad-spectrum antibiotic therapy. He underwent esophagogastroduodenoscopy for dysphagia, which revealed a discrete ulcer positive for CMV. Biopsy of his buccal lesion was ultimately positive for HSV-1 and HSV-2. The patient's clinical status improved significantly following the initiation of antiviral therapy. It is important to consider CMV infection in the setting of persistent fever, respiratory distress, or dysphagia in the non-HIV infected patient, especially in the setting of prolonged steroid use. CMV and HSV infection can occur simultaneously at distinct sites in the body, and CMV infection may predispose to HSV reactivation due to its long term effect on cell-mediated immunity. Early recognition of opportunistic infections and initiation of antiviral therapy in immunocompromised patients can greatly affect length of hospital stay, morbidity, and, ultimately, mortality. |
