N2 - HIV-associated Salivary Gland Disease (HIVSGD) is among the most common salivary gland-associated complications in HIV positive individuals and was associated with the small DNA tumorvirus BK polyomavirus (BKPyV). The BKPyV non-coding control region (NCCR) is the main determinant of viral replication and rearranges readily. This study analyzed the BKPyV NCCR architecture and viral loads of 35 immunosuppressed individuals. Throatwash samples from subjects diagnosed with HIVSGD and urine samples from transplant patients were BKPyV positive and yielded BKPyV NCCR sequences. 94.7% of the BKPyV HIVSGD NCCRs carried a rearranged OPQPQQS block arrangement, suggesting a distinct architecture among this sample set. BKPyV from HIV positive individuals without HIVSGD harbored NCCR block sequences that were distinct from OPQPQQS. Cloned HIVSGD BKPyV isolates displayed active promoters and efficient replication capability in human salivary gland cells. The unique HIVSGD NCCR architecture may represent a potentially significant oral-tropic BKPyV substrain.
