Detection of molluscum contagiosum virus (MCV) DNA in the plasma of an immunocompromised patient and possible reduction of MCV DNA with CMX-001

Abstract

Molluscum contagiosum virus (MCV) is a poxvirus that causes localized papules in healthy persons. We evaluated a woman with severe immunodeficiency and disseminated MCV. During treatment with CMX-001, an antiviral with activity against other poxviruses, MCV DNA was detected in 20% of plasma samples. When the patient was not receiving CMX-001, MCV DNA was detected in 50% of samples. We also noted improvement in warts on her fingers during CMX-001 therapy. Although MCV is caused by direct inoculation of virus into skin in healthy persons, in a severely immunocompromised person MCV DNA was present in blood and may spread by viremia. © 2012 The Author.
