Adenoviruses (AdV), causing fatal disseminated infections in bone
marrow transplant (BMT) recipients, are associated not only with
hemorrhagic cystitis (HC) but also with hepatitis, conjunctivitis, and
viral interstitial pneumonia. The importance of this virus as a cause
of disseminated disease, however, has remained underappreciated. AdV infection has been diagnosed primarily through the use of cell
culture. The fact that cell culture is insensitive for detecting this
virus has hindered recognition of the role that AdV may play in
morbidity and mortality in BMT recipients. To emphasize these points,
we describe a patient who presented with HC due to AdV serotype 11, genotype c, and died with disseminated infection. In addition to cell
culture, this study used a newly developed PCR-based method, capable of
detecting all AdV serotypes tested, including different genotypes of
serotype 11. The PCR result was positive in all culture-positive
samples, including samples of urine, conjunctiva, and bronchoalveolar
lavage (BAL). Importantly, the PCR method provided evidence of urinary
shedding of AdV in a pretransplant, culture-negative specimen and
showed dissemination in a subset of culture-negative specimens,
including BAL, blood, and bone marrow samples. The lack of widespread
awareness of the fact that localized infections may presage
dissemination, and the previous associated lack of rapid, sensitive
diagnostic assays, has impaired recognition of AdV infections in
patients undergoing BMT. Early detection may contribute to therapy
modification and avoidance of unwarranted diagnostic procedures. It may
also assist in epidemiologic control of this highly infectious pathogen
and lead to a renewed interest in preventive and therapeutic approaches.
