Invasive Ureaplasma Infection in Patients Receiving Rituximab and Other Humoral Immunodeficiencies—A Case Report and Review of the Literature

Abstract

Abstract Ureaplasma species are small, fastidious bacteria that frequently colonize the lower reproductive tract of asymptomatic hosts. These organisms have been well described to cause chorioamnionitis, neonatal infection, and urethritis, and to a lesser degree surgical site infection and infection in transplant recipients. Outside of these settings, invasive Ureaplasma infections are rare. We describe the case of a young woman receiving rituximab for multiple sclerosis who presented with fever and bilateral renal abscesses due to Ureaplasma spp., which was successfully treated with oral doxycycline. We searched the literature for cases of invasive Ureaplasma infection and found a patient population that predominates with humoral immunodeficiency, either congenital or iatrogenic. Diagnostic and therapeutic interventions are discussed.
