223. Resolution of novel human papillomavirus-induced warts after HPV vaccination.

Author

Silling, Steffi, Wieland, Ulrike, Werner, Marko, Pfister, Herbert, Potthoff, Anja, and Kreuter, Alexander

Abstract

Human papillomavirus (HPV) XS2 was isolated from warts on an immunosuppressed patient. After HPV vaccination, the warts resolved. HPVXS2 was also found in warts and normal skin of HIV-positive patients and rarely in HIV-negative controls. Further studies should elucidate the mechanisms that lead to wart clearance.

244. High frequency of complex mutational patterns in lamivudine resistant hepatitis B virus isolates.

Author

Neumann‐Fraune, Maria, Beggel, Bastian, Pfister, Herbert, Kaiser, Rolf, and Verheyen, Jens

Abstract

The evolution of hepatitis-B virus (HBV) drug resistance is characterized by the emergence of resistance conferring mutations and compensatory mutations. Therefore HBV drug-resistant isolates often harbor multiple mutations in the reverse transcriptase (RT) and corresponding mutations in the hepatitis B surface antigen (HBsAg). In this study mutational patterns of 60 HBV isolates harboring drug resistance mutations rtM204V or rtM204I were retrospectively analyzed. Both mutations, especially mutation rtM204V, were most often accompanied by compensatory mutations rtV173L and rtL180M but also by mutations conferring entecavir (n = 5) or adefovir resistance (n = 4). In addition, 22 (36.7%) drug resistant HBV isolates carried mutations related to immune escape in the HBsAg. In seven cases premature stop codons in HBsAg were detected resulting in the expression of truncated HBsAg. Clonal analysis of these seven quasispecies even disclosed the presence of HBV isolates carrying further stop codons and in one case the occurrence of resistance mutation rtA181T without the stop codon mutation sW172*. Interestingly, only one HBV clone carried the resistance mutations rtM204V and rtA181T. HBV drug resistant isolates frequently harbored HBsAg mutations associated with immune escape or disease progression pointing to a complex interaction of both proteins. HBV genotypic resistance tests based on population sequencing methods seemed to be inappropriate for determining the clinical relevance of stop codons in the HBsAg. J. Med.

Abstract

There is increasing evidence of an association between human papillomaviruses (HPV) of the beta-genus (beta-PV) and the development of cutaneous squamous cell carcinoma (SCC). The viral DNA load may be an important determinant of pathogenicity, but there are currently no baseline epidemiological data relating to load in people without SCC. We investigated DNA-loads of eight beta-PV types previously associated with risk of SCC. We collected eyebrow hairs from immunocompetent people (ICP) and organ transplant recipients (OTR), determined load by quantitative PCR and obtained demographic, phenotypic, and sun exposure information. Viral loads for ICP from Australia ( n = 241) and Italy ( n = 223) and OTR from across Europe ( n = 318) spanned seven orders of magnitude. The median loads for all types were below one viral DNA copy per 60 cells and were highest for HPV5, HPV8 and HPV20. None of the populations had consistently higher viral loads for all 8 types. However, a higher proportion of OTR were in the top deciles of viral load distributions for six of the eight beta-PV types examined. In a nested analysis of Italian OTR and ICP, this finding was significant for six beta-PV types and cumulative load. Increasing age was significantly associated with higher viral loads in Australia, and there was a weak trend for higher loads with the time elapsed since transplantation in the OTR. We observed a wide distribution of beta-PV loads with OTR significantly more likely to have the highest viral loads. Thus, viral loads may be an important contributor to the higher risk of SCC in OTR. [ABSTRACT FROM AUTHOR]

250. No evidence for a role of xenotropic murine leukaemia virus-related virus and BK virus in prostate cancer of German patients.

Abstract

Prostate cancer is one of the most prevalent types of cancer in men. Controversial data exist concerning the role of BKPyV and the xenotropic murine leukaemia virus-related gammaretrovirus (XMRV) in prostate cancer development. We therefore assessed the association between prostate cancer and viral infections. We could detect BKPyV in only 1 out of 85 prostate cancer samples, whereas none of the tissue samples showed evidence for XMRV positivity. Lack of detection of BKPyV and XMRV in prostate cancer tissues suggests that these viruses do not play a role in the pathogenesis of this type of cancer. [ABSTRACT FROM AUTHOR]
