DHPG effectively treats CMV infection in heart and heart-lung transplant patients: a preliminary report.

Abstract

Cytomegalovirus (CMV) infection in heart and heart-lung transplant recipients represents a serious if not mortal complication. This study reviews the beneficial effects of 9-(1,3-dihydroxy-2-proproxymethyl) guanine (DHPG), an experimental antiviral agent, in patients with CMV infections. Thirteen of 76 heart and heart-lung transplant patients treated with cyclosporine have developed CMV. Nine of 13 patients developed infections since DHPG has been available. Seven patients received hearts, and two received heart and lungs. Six patients were treated, four heart and two heart-lung recipients; five of six had negative CMV serology before surgery, and all had CMV positive donors. Of the patients not treated, one died at home from disseminated CMV; two had resolution of symptoms and were discharged before the diagnosis was made. In the treated group, three patients had gastrointestinal ulcerative disease, two in the stomach and one in the cecum. The other three patients had CMV pneumonia. DHPG was effective in resolving patient symptoms in five of six patients. The patient who did not respond had a cecal ulcer, multiorgan failure, multiple infections, and died. Two patients with abdominal pain had gastric ulcers that were proved with endoscopy. CMV-induced ulcer disease was diagnosed within 2 hours by fluorescent antibody staining, and resolution was documented by endoscopy. Three patients with CMV pneumonia were treated; two were heart-lung transplant recipients. All started to respond within 72 hours. One heart-lung transplant recipient has had a 9-month course of DHPG because of recurrence of infection when the drug was stopped. The usual dosage was 10 mg/kg/day over 2 weeks.(ABSTRACT TRUNCATED AT 250 WORDS)
