A group from Baylor College of Medicine reviewed the efficacy of treating viral infections in transplant patients with primary immunodeficiencies using their viral-specific T lymphocytes. A total of 36 patients were treated with these immunotherapy infusions before or after undergoing hematopoietic stem cell transplantation, and a complete or partial antiviral response were seen in 86% of patients with CMV, 76% of patients with EBV and all patients with adenovirus or HHV-6.
Trial explores immunotherapy for opportunistic viruses in transplantation
A group from Baylor has further characterized the clinical HHV-6B immune response, and is using this new information to develop an enhanced adoptive T cell immunotherapy specific to HHV-6 for HSCT patients.
A novel technique has been developed for the treatment of several viral infections–including HHV-6–following HSCT.
