Disseminated A canthamoeba infection in a heart transplant recipient treated successfully with a miltefosine‐containing regimen: Case report and review of the literature

Disseminated acanthamoebiasis is a rare, often fatal, infection most commonly affecting immunocompromised patients. We report a case involving sinuses, skin, and bone in a 60‐year‐old woman 5 months after heart transplantation. She improved with a combination of flucytosine, fluconazole, miltefosine, and decreased immunosuppression. To our knowledge, this is the first case of successfully treated disseminated acanthamoebiasis in a heart transplant recipient and only the second successful use of miltefosine for this infection among solid organ transplant recipients. A canthamoeba infection should be considered in transplant recipients with evidence of skin, central nervous system, and sinus infections that are unresponsive to antibiotics. Miltefosine may represent an effective component of a multidrug therapeutic regimen for the treatment of this amoebic infection.
