SEN virus (SENV) is a new family of single-stranded DNA viruses with eight different strains, A-H. The modifications in SENV DNA detection and subtype distribution were studied over a long-term follow-up (48+/-32.5 months) in 52 HIV-infected patients. 46% of the patients in the first sample and 34.6% in the second sample were found to have detectable SENV viremia. While the most prevalent variant in the first sample was found to be genotype A (83.3%), the second sample revealed a broader subtype diversification. Several epidemiological and clinical variables were tested in univariate model for clearance of detectable SENV viremia, but none of them reached statistical significance. In conclusion, a high degree of instability of both SENV DNA detection and subtype distribution in a cohort of HIV-infected patients was suggested, which may have important implications for further studies on both SENV epidemiology and its clinical impact.

Abstract
SEN virus (SENV) is a new family of single-stranded DNA viruses with eight different strains, A-H. The modifications in SENV DNA detection and subtype distribution were studied over a long-term follow-up (48+/-32.5 months) in 52 HIV-infected patients. 46% of the patients in the first sample and 34.6% in the second sample were found to have detectable SENV viremia. While the most prevalent variant in the first sample was found to be genotype A (83.3%), the second sample revealed a broader subtype diversification. Several epidemiological and clinical variables were tested in univariate model for clearance of detectable SENV viremia, but none of them reached statistical significance. In conclusion, a high degree of instability of both SENV DNA detection and subtype distribution in a cohort of HIV-infected patients was suggested, which may have important implications for further studies on both SENV epidemiology and its clinical impact.
