Successful treatment of post-transplant CMV meningoencephalitis with third-party CMV virus-specific T cells: Lessons learned.

Cytomegalovirus encephalitis is a challenging life-threatening complication following hematopoietic stem cell transplantation for which medical treatment is usually ineffective or toxic. However, in recent years, adoptive T-cell therapy has been reported to provide a significant chance of cure for patients with viral infections. Herein, two cases of pediatric patients successfully treated with third-party donor-derived virus-specific T cells for CMV meningoencephalitis are reported.
