Antiviral therapy of primary cytomegalovirus infection with vascular thrombosis in immunocompetent adults

Abstract

Background: Vascular thromboembolism (VTE) complicating cytomegalovirus (CMV) primary infection is increasingly reported in immunocompetent adults. No guideline is, however, currently available for the management of these infections and particularly for the antiviral therapy indication.

Methods: We performed a literature review of VTE complicating CMV primary infection in immunocompetent adults using PubMed.

Results: Sixty-nine case patients of VTE complicating CMV primary infection were reported. The main sites of venous thrombosis were the splanchnic veins (30 patients) or those of the lower limbs (18 patients). One-third of patients presented with pulmonary embolism (25 patients). Forty-nine patients (76%) had at least one VTE risk factor, inherited or acquired thrombophilia for 37 patients (58%), and another risk factor for 27 patients (42%). Only 11 patients received an antiviral therapy. A positive outcome was observed in all patients.

Conclusion: We suggest that antiviral therapy should be considered for patients presenting with severe VTE, VTE with a negative outcome despite anticoagulation, severe organ involvement, or for patients managed in the intensive care unit.
