title: Acyclovir prophylaxis of oral herpes virus during bone marrow transplantation.
abstract: Oropharyngeal shedding of herpes viruses (herpes simplex, cytomegalovirus) was assessed in patients on standard acyclovir prophylaxis during bone marrow transplantation (BMT) to determine the frequency of viral shedding and to assess possible oropharyngeal complications that may be associated with viral reactivation in these patients. We conducted a prospective assessment of 83 patients receiving BMT. Patients were evaluated weekly and oral surveillance cultures were completed. Shedding of herpes simplex virus (HSV) was detected in the oropharynx of 2.9% of seropositive patients on prophylactic acyclovir, and only one case of clinical oral herpetic infection was seen. Cytomegalovirus (CMV) was cultured from the oropharynx in 13.3% of CMV seropositive patients provided with prophylactic acyclovir, but no oropharyngeal lesions were attributed to CMV reactivation. No correlation was seen between HSV and CMV pretransplant serology and severity of oral mucositis and acute graft versus host disease. No effect on time to engraftment was detected. This study supports the continuing use of acyclovir prophylaxis in HSV seropositive patients receiving BMT. Acyclovir prophylaxis was effective in preventing viral shedding in all but 2.9% of patients, and only one case of clinical infection was diagnosed. The frequency of CMV shedding was approximately four times that of HSV; however, no oral lesions were attributed to CMV.
