Adenovirus disease can cause disseminated disease or lethal organ damage in patients undergoing hematopoietic cell transplantation (HCT). Renourinary infection is the most common in Japan. The 1-year cumulative incidences of adenovirus disease in children and adults were 0.15% and 0.49%, respectively, after autologous HCT, and 1.52% and 2.99%, respectively, after allogeneic HCT. The annual incidence remained above 100 cases. Viremia or disseminated disease after autologous and allogeneic HCT occurs in 6% and 19%, respectively, in patients with adenovirus disease. Age ≥50 years and lymphoma are associated with adenovirus disease after autologous HCT. Patient age ≥50 years, male patients, adult T-cell leukemia/lymphoma, lymphoma, HCT-specific comorbidity index ≥3, HLA-mismatched or haploidentical donors, cord blood, in vivo T-cell depletion, grades II-IV acute graft-versus-host disease (GVHD), and extensive chronic GVHD are associated with adenovirus disease after allogeneic HCT. No regulatory authority has approved an antiviral agent for treating adenovirus disease after HCT. More than half of the patients received only supportive care in Japan. The increased risk of mortality following developing adenovirus disease, even with a single-site infection, after both autologous and allogeneic HCT suggests an urgent unmet need for the development of safe and effective drugs.
