Disseminated Ureaplasma polyarthritis in a renal transplant recipient
Abstract
BACKGROUND: The risk of infection following kidney transplant increases substantially in the setting of hypogammaglobulinemia and T-cell-depleting therapy. Ureaplasma has been described to cause invasive disease in immunocompromised hosts with humoral immunodeficiency. We describe a kidney transplant recipient with history of antineutrophil cytoplasmic autoantibody (ANCA) vasculitis remotely treated with rituximab who developed Ureaplasma polyarthritis following transplant. The purpose of this report is to highlight the unique risks that kidney transplant patients face particularly if hypogammaglobulinemic.
CASE REPORT: Patient is a 16-year-old female with history of granulomatosis with polyangiitis (GPA) treated with maintenance dose of rituximab 13 months prior to transplant. Patient underwent deceased donor kidney transplant with thymoglobulin induction. IgG was 332 mg/dL and CD20 was zero at the time of transplant. One month posttransplant, the patient developed polyarticular arthritis without fever, pyuria, or evidence of GPA reactivation. MRI had diffuse tenosynovitis, myositis, fasciitis, cellulitis, and effusions of three involved joints. Bacterial, fungal, and AFB cultures remained negative, but 16 s ribosomal PCR testing from joint aspirates detected Ureaplasma parvum. The patient was treated with levofloxacin for 12 weeks with the resolution of symptoms.
CONCLUSIONS: Ureaplasma infection is an under-recognized pathogen in kidney transplant patients. A high index…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
