The objective of a cross sectional study is to describe the situation of human papillomavirus (HPV) infection and risk behaviours among 800 men who have sex with men (MSM) in Hanoi and Ho Chi Minh City (HCMC) from December 2017 to May 2018 using respondent - driven sampling method (RDS). The results showed that the prevalence of any type of HPV infection was 29.8% (33% in HCMC, 26.5% in Hanoi) and the prevalence of any high - risk type of HPV infection was 24.0% (29.0% in HCMC, 19.0% in Hanoi). The risk behaviours to HPV among MSM in both cities included: Alcohol use (69.9%), smoking (30.7%), drug use (8.5%), having frst sexual intercourse under 18 years old (31.8%), having group sex (10.5%), having sex with both men and women (21.7%). The factors which had statistically signifcant differences with HPV status in MSM group included: City, age group, and marital status. These results showed that there is a need for medical interventions for MSM to improve individual health as well as to minimize the transmission of HPV in this population.

Human papillomavirus (HPV) is the most common sexually transmitted infection in the world. Several studies have shown a higher prevalence of HPV infection in HIV-infected women. The aim of this study was to determine the prevalence and the genotype diversity of HPV infection in HIV-infected women. From April 2010 to December 2012 cervical specimens were collected from 169 HIV-infected women who screening for cervical cancer at Reference Unit in Belém. The detection of HPV infection was performed by nested PCR and HPV type was performed using a commercial system. The prevalence of HPV infection was 63.3%. Of the 47 genotyped samples, 40.4% was found positive for high risk-HPV 16 and 12.8% for high risk-HPV 52. HPV infection was predominant in the group of women with no incidence of cytological abnormalities and more prevalent in women of reproductive age, unmarried, low education level, and who reported use condoms during sexual intercourse. It was observed an association between HPV infection and independent variables, such as condom use, multiple sexual partners, and history of sexually transmitted diseases. High-risk types of HPV infection were prevalent in our study. Infection with multiple high-risk HPV genotypes may potentiate the development of cervical cancer in HIV-infected women.

Abstract Background Human papillomavirus (HPV) infection is a public health problem in Africa because of its frequency and its various consequences in both men and women. In Burkina Faso, there is little data on the carriage of HPV infection in male subjects. This study aimed to determine the carriage of HPV infection in male subjects in Ouagadougou, Burkina Faso.Methods This was a cross-sectional study conducted from December 2015 to September 2016. During this study period, a total of 124 male subjects who gave informed consent were recruited as part of a fertility assessment. Semen samples were analyzed by Real- Time PCR using Real TM Quant High Risk Screen HPV kit to detect 14 high-risk HPV genotypes. The Chi square test was used for comparisons.Results Of the 124 male subjects, 22 were positive for at least one high-risk HPV, with a prevalence of 17.7%. HPV 56 was the most represented genotype with a frequency of 20%, followed by HPV 39 (11%) and HPV 68 (11%), HPV 16 (8%). The genotypes HPV 18, HPV33, HPV35, HPV51 and HPV52 also had the same frequency of 6% each and the HPV 31, 45, 59 and 66 had the same frequency of 3% each. Of the 22 positive cases, 10 were multiple infections. Spermocytogram of patients showed at least one abnormality in 87.9% of cases. Necrozoospermia and oligozoospermia were the most abnormalities observed with 42% and 40% respectively followed by asthenospermia (18%); teratozoospermia (16%) and azoospermia (14%).Conclusion This study showed that like women, men are infected by HPV with a relatively high prevalence. In addition, the predominant genotypes in the male subjects of this study are not those targeted by the HPV vaccines available in our countries. Hence the need to reinforce the strategies for controlling HPV infection and HPV prophylactic vaccination for young boys.

Men who have sex with men (MSM) and purchase sex (MPS) are a sub-group potentially at high risk for acquiring and transmitting sexually transmitted infections (STIs). This is a hard-to-reach population resulting in a scarcity of studies covering the issue. This cross-sectional study aimed to assess the association between purchasing sex and high-risk behaviors related to HIV/STI transmission and appraise the STI prevalence among MSM. All MSM who attended the STI clinic in Tel Aviv between 2003 and 2010 were included. Demographics, behavioral, clinical, and laboratory data were compared between MPS and non-MPS to identify high-risk sexual behaviors and STI prevalence associated with purchasing sex. Of the first visits of 2694 MSM who attended the STI clinic during the study period, 151 (5.6%) paid for sex. MPS were more commonly older and married than non-MPS. MPS were more likely to engage in behaviors associated with high risk for HIV/STI transmission, including infrequent condom use during anal sex, substance use during sex, and selling sex themselves. MPS had a higher STI prevalence than non-MPS, although this was not statistically significant ( p = 0.05). These findings highlight the need to establish culturally tailored interventions for MPS addressing the potential risks associated with purchasing sex.

SUMMARY High-risk human papillomavirus (hr-HPV) infection is necessary but not sufficient for cervical cancer development. Recently, P16INK4A gene silencing through hypermethylation has been proposed as an important cofactor in cervical carcinogenesis due to its tumor suppressor function. We aimed to investigate P16INK4A methylation status in normal and neoplastic epithelia and evaluate an association with HPV infection and genotype. This cross-sectional study was performed with 141 cervical samples from patients attending Hospital Moncorvo Filho, Rio de Janeiro. HPV detection and genotyping were performed through PCR and P16INK4A methylation by nested-methylation specific PCR (MSP). HPV frequency was 62.4% (88/141). The most common HPV were HPV16 (37%), HPV18 (16.3%) and HPV33/45(15.2%). An upward trend was observed concerning P16INK4A methylation and lesion degree: normal epithelia (10.7%), low grade lesions (22.9%), high grade (57.1%) and carcinoma (93.1%) (p < 0.0001). A multivariate analysis was performed to evaluate an association between methylation, age, tobacco exposure, HPV infection and genotyping. A correlation was found concerning methylation with HPV infection (p < 0.0001), hr-HPV (p = 0.01), HSIL (p < 0.0007) and malignant lesions (p < 0.0001). Since viral infection and epigenetic alterations are related to cervical carcinoma, we suggest that P16INK4A methylation profile maybe thoroughly investigated as a biomarker to identify patients at risk of cancer.
