Late cytomegalovirus disease with atypical presentation in renal transplant patients: case reports

Transplant Proc. 2004 Jul-Aug;36(6):1841-3. doi: 10.1016/j.transproceed.2004.07.017.

Abstract

Cytomegalovirus (CMV) disease typically occurs 1 to 4 months (median 35 days) after solid organ transplantation. Recent reports documented that the natural history of CMV disease associated with solid organ transplantation has been modified as a result of the widespread use of potent immunosuppressents and antiviral prophylaxis. We herein report three pretransplant CMV seropositive recipients (with unknown donor status) who were diagnosed recently to display late and atypical CMV disease. Two men and one woman included two patients who presented with allograft dysfunction at 12 years and at 3 years after transplantation. Both patients showed increased serum creatinine approximately from baseline 200 to >400 micromol/L over 3 months in the absence of features of rejection or cyclosporine toxicity. A renal biopsy was refused by both patients. Two of the three patients presented with symptoms of enterocolitis (diarrhea, nausea, weight loss), which had persisted for more than 6 months. Other symptoms and signs of overt CMV disease (fever, leukopenia) were absent. None had pulmonary, hepatic, or other major organ involvement. In all patients IgG antibodies and CMV DNA by polymerase chain reaction were positive with negative IgM antibodies. The immunosuppressive regimen consisted of mycophenolate mofetil (MMF), steroids, and calcineurin inhibitors. The kidney function significantly improved in both patients with renal dysfunction. Gastrointestinal symptoms resolved completely with gradual weight gain. The recognition and early diagnosis of late atypical CMV disease in kidney transplant patients presenting with allograft dysfunction and/or other organ systems is important. The MMF has a red herring effect in our cases due to its GI side effects.
