Abstract
BACKGROUND Anal cytology may be useful for evaluating lesions associated with human papillomavirus (HPV) in individuals at increased risk for anal cancer. METHODS Liquid-based cytology was used to assess anal cytological lesions among human immunodeficiency virus (HIV)-infected and HIV-uninfected men who have sex with men (MSM). The Linear Array HPV genotyping test was used for HPV detection. RESULTS This cross-sectional study included 1021 MSM, of whom 388 were HIV-infected (38.0%). Anal cytological lesions (atypical squamous cells of undetermined significance or more severe [ASCUS+]) were observed in 32.5% and 53.2% of the HIV-uninfected and HIV-infected individuals, respectively (P < .0001). The highest ASCUS + prevalence was observed among ≥45-year-old HIV-uninfected MSM (37.3%) and 25-to 29-year-old HIV-infected MSM (66.7%). High-grade squamous intraepithelial lesions (HSILs) peaked in ≥ 45-year-old HIV-uninfected subjects and 35- to 39-year-old HIV-infected subjects. Individuals with anal infections with high-risk (HR) HPV types were 3 to 4 times more likely to have an ASCUS + report. An HPV-16 and/or HPV-18 infection increased the odds of HSIL or more severe cytology (HSIL+) for HIV-infected MSM almost 4 times. MSM concurrently infected with HR and low-risk HPVs were significantly more likely to have low-grade squamous intraepithelial lesions or more severe cytology (LSIL+) than those infected with only HR types. No significant associations were found between cytological abnormalities and the HIV load and nadir and current CD4 + counts. CONCLUSIONS The prevalence of anal cytological lesions is high in MSM, even in HIV-infected individuals treated with combined antiretroviral therapy. In these subjects, HSILs occur more frequently and at a younger age in comparison with HIV-uninfected counterparts. Specific diagnostic procedures should be implemented to manage individuals at increased risk for anal cancer with an abnormal anal Papanicolaou test.

Abstract
Objectives: To prospectively examine the association between human papilloma virus (HPV) colonization of the colonic mucosa and the development of colorectal polyps (CRPs), and colorectal cancer (CRC) in Saudi Arabia. Methods: A case control study was performed between January 2013 and December 2014. All eligible patients underwent standard diagnostic colonoscopy. Patients with polyps or colorectal cancer were considered cases, while those with any other endoscopic findings were controls. Biopsy samples from polyps and tumors, and/or from normal colonic mucosa were acquired. Human papilloma virus colonization was detected using a hybrid capture technique of samples taken from both normal tissue, and CRPs and CRC. The association between HPV and CRPs/CRC was evaluated. Results: A total of 132 patients were recruited. The mean age was 53 (±15.9) years. Sixty patients had endoscopically detectable CRPs/CRC, and 72 had either inflammation or normal endoscopic evaluations. Only 4 (0.8%) of the 132 samples that were collected and analyzed were positive for the HPV gene. Statistical analysis did not identify any significant association between HPV colonization and the presence of CRPs/CRC. The only significant predictor of detecting CRPs/CRC on colonoscopy was symptomatic presentation (odds ratio=11.072, 95% confidence interval 4.7-26.2, p<0.001). Conclusion: Human papilloma virus colonic colonization is rare in Saudi Arabia. An association between HPV colonization and CRP/CRC development could not be identified in this cohort of patients.

Abstract
BACKGROUND We studied anal specimens to determine the distribution of human papillomavirus (HPV) genotypes and co-infection occurrence. This information will contribute to the knowledge of HPV genotype distributions and provide an estimate of the prevalence of different oncogenic HPV genotypes found in patients in Madrid (Spain). METHODS We studied a total of 82 anal biopsies from the Hospital General Universitario Gregorio Marañón of Madrid. These included 4 specimens with benign lesions, 52 specimens with low-grade anal squamous intraepithelial lesion, 24 specimens with high-grade anal squamous intraepithelial lesions and 2 specimens with invasive anal carcinoma. HPV genotyping was performed with PCR amplification and reverse dot blot hybridization. RESULTS We detected 33 different HPV genotypes, including 16 HPVs associated with a high risk of carcinogenesis, 3 HPVs associated with a highly likely risk of carcinogenesis and 14 HPVs associated with a low-risk of carcinogenesis. In two specimens, an uncharacterized HPV genotype was detected. The most frequent HPV genotypes found were HPV-16 (10.3%; 95% CI: 6.6%-15.1%), HPV-52 (8.5%; 95% CI: 5.2%-13%) and HPV-43/44 (7.6%; 95% CI: 4.5%-11.9%). HPV-18 was only detected in 0.9% (95% CI: 0.1%-3.2%) of the total viruses detected in all lesions. HPV co-infections were found in 83.9% of all types of lesions. The majority of cases (90.2%) were concomitantly infected with the human immunodeficiency virus (HIV). CONCLUSION The prevalence of high-risk carcinogenic genotypes in anal pathological samples was remarkable. Therefore, further studies that include a greater number of samples, particularly invasive carcinoma cases are needed to evaluate the potential influence of these HPV genotypes in the appearance of anal carcinomas. Also, the influence of other accompanying infections should be evaluated clarify the appearance of this type of carcinoma.

Abstract
In order to investigate the genomic diversity of low-risk human papillomavirus (HPV) genotypes, a total of 108 isolates of HPV 40, HPV 42, HPV 43, or HPV 44, obtained from anal swabs or tissue specimens of patients with anogenital warts, and cervical swabs of women with cervical intraepithelial neoplasia of different grades, were analyzed. The characterization of genomic variants was established by sequencing one third of the viral genome and analysis of three different genomic regions: L1, LCR, and E6. Maximum variant divergence accounted for 0.4-1.1% of the investigated genomic segments. Several novel, potentially important nucleotide substitutions, deletions, and insertions are described. Altogether, among 14 HPV 40 isolates, a total of nine different genomic variants were identified, composed of eight L1, five LCR, and four E6 genomic variants. Among 49 HPV 42 isolates, a total of 30 genomic variants were identified, composed of 20 L1, 18 LCR, and four E6 genomic variants. Among 10 HPV 43 isolates, distributed into two major genomic variant lineages with clearly defined nucleotide signatures, three genomic variants were identified, composed of three L1, two LCR, and two E6 genomic variants. Among 35 HPV 44 isolates, a total of eight HPV 44 and 11 subtype HPV 44 genomic variants were identified, composed of 13 L1, 14 LCR, and 6 E6 genomic variants. A similar level of genomic diversity of HPV 44 and its subtype was identified in our geographic region as has been reported previously on isolates collected worldwide.

Abstract
Background The incidence of anal cancer, a Human Papillomavirus (HPV)-related neoplasia, has been increasing in recent decades, mainly in men who have sex with men (MSM). Cytological changes of the anal epithelium induced by HPV can be detected through an anal pap smear. This study aimed to evaluate the prevalence and epidemiological correlates of anal cytological abnormalities among relatively young MSM at risk for HIV-1 infection, to help clarify whether or not this population deserves further investigation to assess the presence of anal cancer precursor lesions. Methods MSM were recruited among attendees of a large STI clinic for a HIV-1 screening program. Anal samples, collected with a Dracon swab in PreservCyt, were used both for liquid-based cytology and HPV testing by the Linear Array HPV Genotyping Test. Data regarding socio-demographic characteristics and sexual behavior were collected in face-to-face interviews. Results A total of 346 MSM were recruited (median age 32 years). Overall, 72.5% of the individuals had an anal HPV infection, with 56.1% of them being infected by oncogenic HPV genotypes. Anal cytological abnormalities were found in 29.8% of the cases (16.7% ASC-US and 13.1% L-SIL). Presence of ASC-US+ was strongly associated with infection by any HPV type (OR=4.21, 95% CI: 1.97-9.23), and particularly by HPV 16 and/or 18 (OR=5.62, 95% CI: 2.33-13.81). A higher proportion of ASC-US+ was found in older MSM, in those with a higher number of lifetime partners and in those with a history of ano-genital warts. However, none of these variables or the others analyzed showed any significant association with abnormal cytological findings. Conclusions The presence of anal cytological abnormalities in about one third of the recruited MSM and their strong association with HPV infection, in particular that caused by HPV 16 and/or 18, might provide a further complement to the data that now support the introduction of HPV vaccination among MSM to protect them from the development of HPV-associated diseases. Additional studies are needed to determine whether and how screening for anal cancer precursor lesions should be performed in younger MSM.

Abstract
Multiple types of human papillomavirus (HPV) are responsible for most cervical cancers but also cause anal cancers-especially in HIV-positive patients. Furthermore, men who have sex with men (MSM) are twice as likely to develop anal cancers as non-MSM. A simple screening test for HPV infection would be useful in these patients. The aim of our study was to evaluate the detection of HPV by real-time polymerase chain reaction (PCR) in urine as a marker of anal infection in MSM. The study included 52 HIV-positive MSM treated at Amiens University Hospital (Amiens, France). After obtaining informed consent, we performed an anal swab and gathered 10 mL of first-void urine. Samples were extracted and amplified in a real-time PCR. Genotypes were determined with a PapilloCheck(®) system (Greiner Bio-One, Frickenhausen, Germany). The anal test was the gold standard for calculating the characteristics of the urine test. The sensitivity of the urine test for diagnosing anal HPV infection was 15%, the specificity was 66%, the positive predictive value was 87.5%, and negative predictive value was 4.5%. The prevalence of anal HPV infection in the study population was 94%. Genotype 42 was the most common. The anal HPV viral load was significantly lower in men in a stable relationship than in single men. However, there was no statistically significant relationship between anal viral load and anal intraepithelial lesions. We conclude that urine-based HPV is a poor predictor of anal HPV infection in HIV-positive MSM.

Abstract
BACKGROUND Anal human papillomavirus (HPV) infection is very common in men having sex with men (MSM), but the available data on its burden and characteristics mainly concern HIV-infected individuals. OBJECTIVES This study aimed to assess the prevalence, spectrum of genotypes, and determinants of the anal HPV infection in metropolitan HIV-1 uninfected MSM. STUDY DESIGN A cohort of 258 MSM (median age 32 years, IQR 26-39) enrolled at an STI Clinic was screened for anal HPV infection using a highly sensitive PCR-based genotyping method. Medical history and behavioral data were collected. RESULTS Overall, 74.8% of the MSM were HPV-positive, with 56.2% of the participants being infected by high-risk (HR) types. A multiple infection was detected in 65.3% of the HPV-positive MSM, with up to 10 different HPV types detected in the same sample. A broad spectrum of infecting HPV types was observed, with 36 different types found overall and HPV16 representing the most common type (17.8%). The lifetime and recent number of sexual partners as well as having receptive anal sex were significantly associated with the anal HPV infection, confirming the role of sexual behavior in risk of HPV infection. However, neither younger age at first intercourse nor inconsistent use of condom was significantly associated with the infection. CONCLUSIONS The present findings highlight the need to create a more significant awareness about the risk of anal HPV infection among HIV-uninfected MSM and warrant the investigation of possible anal intraepithelial lesions, particularly in view of the increasing anal cancer incidence in high-risk populations.
