The aim of this study was to evaluate the frequency of "high-risk" HPV types in condyloma acuminata in patients from Tunisian Center. Thirty two paraffin-embedded biopsies were analysed for the presence and type of HPV DNA by means of in situ hybridization (ISH) and polymerase chain reaction (PCR) techniques. ISH was done using a broad spectrum HPV biotinylated DNA probe for the detection of HPV DNA. HPV typing was carried out using specific probes for HPV types 6/11, 16/18 and 31/33. HPV DNA was amplified by PCR using the degenerate primers E1350L/E1547. HPV were typed by pU-1M/PU-2R primers for the oncogenic HPV types 16, 18, 31 and 33, and PU-31B/PU-2R for "low-risk" group (6 and 11). Using ISH, HPV was detected in 27 out 32 cases (84.4%). All were HPV 6/11 positive. Co-infection with oncogenic HPV was found in one case that reacted with 16/18 and 31/33 probes. Good quality DNA was obtained in 13 cases. HPV was detected by PCR in 11 of 13 specimens (80.6%) when E1350L/E1547 primers were used. HPV 6/11 were present in all cases. The results of this study provide specific confirmation of the predominance of HPV6/11 and low rate of co-infection in patient from Tunisian Center. Because of the difficulty of DNA extraction, risk of DNA degradation and contamination associated with PCR, the ISH remains more adapted to archival materiel especially in routine clinical practice. |
