Probable Donor-Derived Cytomegalovirus Disease After Keratolimbal Allograft Transplantation
Abstract
PURPOSE: To report a case of probable donor-derived cytomegalovirus (CMV) infection after keratolimbal allograft (KLAL) transplantation.
METHODS: Observational case report.
RESULTS: A 41-year-old man with a history of aniridic keratopathy and limbal stem cell deficiency underwent KLAL in his right eye. Preoperatively, he was negative for CMV IgG and IgM. Postoperatively, he was maintained on tacrolimus and mycophenolate mofetil for systemic immunosuppression; he was also on prophylactic valganciclovir (for CMV) and trimethoprim/sulfamethoxazole (for pneumocystis pneumonia) for 1 month. Approximately 5 weeks postoperatively, he developed a nonproductive cough, rhinorrhea, and dyspnea. His condition did not improve with oral azithromycin or levofloxacin. He developed worsening symptoms over the next 2 weeks despite therapy. The serum CMV polymerase chain reaction was positive, and he was readministered valganciclovir with subsequent resolution of symptoms.
CONCLUSIONS: We present the first case of CMV disease in a seronegative patient who received a presumed CMV-seropositive donor KLAL. Similar to solid organ transplantation, prophylactic and therapeutic management of CMV infection is necessary in the setting of systemic immunosuppression.
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.
