Human papillomavirus (HPV) types specific of epidermodysplasia verruciformis detected in warts induced by HPV3 or HPV3-related types in immunosuppressed patients.

Epidermodysplasia verruciformis (EV) is characterized by an abnormal genetic predisposition to infection with specific types of human papillomavirus (HPV). Specific defects of the cell-mediated immunity and/or of the control of HPV infection in keratinocytes are assumed to be involved in the development of the disease. As a model to test this hypothesis, we have studied the prevalence of EV-specific HPV in skin warts of 56 immunosuppressed patients. All main types of cutaneous HPV (HPV1, 2, 3, 4, 10, and 28) responsible for skin warts in the general population were detected by blot hybridization. EV-specific HPV (HPV5, 20, and 23) were detected in three patients. Four additional patients were found infected with HPV49, first characterized in the course of this study, and found to be related to EV HPV. A most important finding was that HPV5, 20, 23, and 49 were always codetected with HPV3 or the related types HPV10 and 28. None of the specimens showed the typical clinical morphology of EV lesions. In none of these specimens was the specific cytopathic effect of EV recognized; instead that of HPV3 and related types was seen. No evidence for productive EV HPV DNA replication was obtained for the three specimens that could be further analyzed by in situ hybridization. Our data suggest that HPV3 infection favors infection with EV HPV in immunosuppressed patients but that the full expression of EV HPV is usually restricted as in the general population.

Human papillomavirus: a highly prevalent sexually transmitted disease agent among female sex workers from Mexico City

BACKGROUND: Cervical cancer, a human papillomavirus (HPV)-caused neoplasia, is highly prevalent in Mexico. GOAL: To determine the prevalence of HPV infection in female sex workers (FSW) from Mexico City and to assess the association between HPV infection and the characteristics of these women. STUDY DESIGN: A questionnaire was applied to 495 FSW. Cervical cell specimens were obtained for DNA amplification and hybridization to detect 27 HPV types. A risk factor analysis was performed. RESULTS: The overall prevalence of HPV infection was 48.9%. The prevalence of high-risk HPV types was 43%, whereas that of low-risk types was 24.6%. A total of 18.8% of study participants was infected with both high-risk and low-risk HPV types, and 28.5% were infected with two or more HPV types. Younger age and failure to use a condom were independently associated HPV risks (odds ratio, 7.3 and 2.3; 95% CI, 3.5-15.0 and 1.2-4.4, respectively). CONCLUSIONS: Infection with high-risk and multiple HPV types is high among Mexican FSW. This study corroborated a higher infection rate in younger women. A higher risk of HPV infection is also observed in women who have been involved with sex work for less than 1 year. However, condom use showed a protective effect against HPV infection.

Human papillomavirus infection in men who have sex with men participating in a Dutch gay-cohort study

BACKGROUND: To develop strategies for prevention and early treatment of human papillomavirus (HPV) anal and penile cancer, a better understanding of related sexual behavior risk factors is needed. GOAL: The goal of this study was to establish the prevalence of anal and coronal sulcus HPV in a group of men who have sex with men participating in a Dutch gay-cohort study, to identify risk factors associated with HPV infection in this group, and to investigate the presence of identical HPV types in couples with stable relationships. STUDY DESIGN: A cross-sectional study of 241 HIV-negative and 17 HIV-positive men who have sex with men visiting the sexually transmitted disease clinic of the Erasmus MC for a regular and scheduled examination. Participants underwent a routine venereological examination including HIV serologic analysis, and swabs were taken from the coronal sulcus and anus for HPV DNA testing. All subjects were asked to complete a questionnaire on sexual risk behavior. RESULTS: HPV DNA was detected at the coronal sulcus in 23.5% of the HIV-positive men and in 15.8% of the HIV-negative men (P=0.492). In anal specimens, HPV DNA was detected in 64.7% of the HIV-positive men and 32.8% of the HIV-negative men (P=0.015). High-risk HPV types (P=0.007) and 2 or more different HPV genotypes (P=0.006) were seen more often in anal specimens of HIV-positive persons than in specimens of HIV-negative persons. A factor possibly associated with the presence of anal HPV infection was a concomitant anal infection with Chlamydia trachomatis, gonococci, or herpes simplex virus (P=0.059). In only 16.7% of HPV-positive steady couples, both companions showed the presence of one or more identical HPV genotypes. CONCLUSION: In this study, anal HPV DNA was detected more often than HPV DNA at the coronal sulcus. HIV positivity was associated with a higher prevalence of high-risk, but not with low-risk HPV types, at the anus. No association was found between HIV positivity and presence of high-risk HPV at the coronal sulcus. No sexual behavioral determinants for the presence of HPV could be identified. Concomitant anal infection with C trachomatis, gonococci, or herpes simplex virus may be associated with HPV infection. In the majority of steady couples, partners were infected with different HPV types.     

Distribution of human papillomavirus types in cervicovaginal washings from women evaluated in a sexually transmitted diseases clinic

BACKGROUND: Women evaluated for sexually transmitted diseases (STDs) may be at increased risk for human papillomavirus (HPV) infection, a condition associated with cervical dysplasia. The distribution of HPV types in such a population is unknown. GOAL: The goal was to determine the prevalence of HPV infection, the distribution of HPV types, and the type distribution in relation to cervical dysplasia in women in an STD clinic. STUDY DESIGN: Cervicovaginal lavage and Papanicolaou smear specimens were obtained from 295 women. Lavage specimens were analyzed for HPV by polymerase chain reaction/reverse blot strip assay. RESULTS: Cervical cytologic findings were abnormal for 19.7% of women. HPV DNA was detected in 49.2% of women (high-risk HPV in 42.4%). HPV positivity correlated with the degree of cytologic abnormality. In women with dysplasia, HPV types 16, 66, 83, 56, 52, and 59 were commonly detected. Specimens containing abundant HPV DNA occurred most often in women with dysplasia. CONCLUSIONS: HPV infection was common in women attending an STD clinic. Numerous individual HPV types were associated with cervical dysplasia, including "low-risk" types.
