Hyperammonaemia syndrome in disseminated Ureaplasma parvum infection

Abstract

Hyperammonaemia syndrome secondary to Ureaplasma spp. infection is well documented in the post-lung transplant population. We report a case of a man in his fifties with hyperammonaemia syndrome secondary to disseminated Ureaplasma parvum infection. This occurred in the context of immunosuppression for chronic graft versus host disease and six years following an allogeneic stem cell transplant for diffuse large B-cell lymphoma. Following treatment of U. parvum septic arthritis with ciprofloxacin and doxycycline, the patient experienced a full neurological recovery, and continues on suppressive doxycycline therapy with no recurrence of symptoms to date.
