A 51-year-old renal transplant recipient presented with a 3-week history of progressive diffuse abdominal pain without diarrhea, vomiting or fever. His medical history was notable for diabetes mellitus and end stage renal disease secondary to immunoglobulin (Ig) A nephropathy. He had undergone living unrelated kidney transplant 11 years and again 4 years earlier. The first transplant failed owing to recurrence of IgA nephropathy in the allograft, and the second transplant was without complications. The patient was seronegative for cytomegalovirus IgG, as were both kidney donors. Epstein-Barr virus donor and recipient serologic results were positive. Immunosuppressive medications included mycophenolate 100mg twice daily, tacrolimus 2 mg every morning and 1 mg every evening, and prednisone 7.5 mg daily. The patient reported multiple sexual partners over the last 5 months, both men and women.
