Thrombotic microangiopathy in association with cytomegalovirus infection in a renal transplant patient: a new treatment strategy.
BACKGROUND
Cytomegalovirus (CMV) associated with thrombotic microangiopathy (TMA) in transplant patients has not been extensively described. This case illustrates an association between CMV and TMA in a transplant patient with resolution of the latter after treatment of the CMV.


RESULTS
At 6 weeks after renal transplantation, a 57-year-old woman presented with TMA. Cyclosporine was discontinued, and plasmapheresis was started. However, the patient continued to deteriorate and developed CMV pneumonitis. Plasmapheresis was discontinued, and intravenous ganciclovir was initiated. Both the TMA and the CMV resolved after initiation of the ganciclovir.


CONCLUSIONS
This case identifies another potential etiological factor in the development of TMA after renal transplantation. It is the first reported case of TMA being cured with treatment of CMV.
