- Abstract
Though typically self-limiting, severe mpox infections have been treated with antiviral medications, most notably tecovirimat. Various reports exist of mpox progression despite tecovirimat treatment. Treatment resistance can be due to acquired mpox strain mutations, most often occurring in an immunocompromised host. We present the case of a male with AIDS who developed disseminated treatment-resistant mpox infection complicated by superimposed bacterial and fungal infections. His orthopoxvirus polymerase chain reaction result remained positive despite treatment with 4 weeks of oral tecovirimat and 3 doses of intravenous cidofovir. Poor response to antiviral therapy was likely due to his underlying immunocompromised state; however, strain resistance cannot be ruled out given that the patient had started but not completed a 14-day course of tecovirimat 8 months prior, at the time of initial mpox diagnosis. Patients with mpox who are immunocompromised may require extended and additional treatment beyond the standard 14 days of tecovirimat, such as cidofovir, brincidofovir, or intravenous vaccina immune globulin.
