Además los antecedentes previos de VPH tienen asociación estadística con el ASCUS OR=36,69 IC 95% (3,56-378,15) y con las vaginosis por Gardnerella OR=10,57 IC 95%(1,07-104,64), mientras que las infecciones urinarias tuvieron asociación estadística con la candidiasis OR=4,46 IC 95% (1,21-16,5).Enfermería Global Nº 50 Abril 2018 Página 87Conclusiones: Los hallazgos encontrados pueden servir como información descriptiva acerca de la frecuencia de IV y LEICU en poblaciones universitarias para continuar o mejorar programas de promoción y prevención de la salud sexual y reproductiva, en poblaciones jóvenes. Objective: To explore the risk factors associated with vaginal infections and squamous intraepithelial lesions of the cervix in university students in Medellín, Colombia.Materials and methods: Cross-sectional study; a convenience sample of 176 students from the health care field were included. Data were obtained through an anonymous survey that included demographic, clinical, and academic variables, as well as those pertaining to sexual habits. Cervical cytology and direct gram stain of vaginal fluid were taken. The statistical association for vaginal infections and squamous intraepithelial lesions of the cervix was explored through the odds ratio and the 95% confidence intervals (95% CI). A p value <0.05 was considered statistically significant. Results: Atypical squamous cells of undetermined significance (ASCUS) was found in 9.1% of participants; low-grade cervical squamous intraepithelial lesions in 4.5%, and vaginal infections in 30.7%; bacterial vaginosis was the most common infection. Previous history of HPV has a statistical association with ASCUS OR = 36.69 95% CI (3.56-378.15) and vaginosis by Gardnerella OR = 10.57 CI 95% (1.07-104.64), whereas urinary infections had a statistical association for candidiasis OR = 4.46 CI 95% (1.21-16.5).Conclusions: Our findings can be used as descriptive information regarding the frequency of vaginal infections and squamous intraepithelial lesions of the cervix in university populations, to continue or improve programs for the promotion and prevention of sexual and reproductive health in young populations.

A cohort of 77 women referred for routine screening or investigation of Pap test abnormality underwent colposcopic examination. Pap-stained liquid-based preparations were diagnosed and categorized according to the Bethesda system. Residual material on the sampling device was used to detect high-risk oncogenic human papillomavirus DNA. Although the colposcopic failure rate was higher than that of cytology, no lesion was missed when both methods were used together. High-risk types were recorded in 24% of patients with atypical squamous cells of undetermined significance, 45% with low-grade squamous intraepithelial lesions and 79% with high-grade squamous intraepithelial lesions-indicating that the efficacy of cytological screening can be improved by papillomavirus detection.

Background: ThinPrep® (TP) cervical cytology, as a liquid-based method, has many benefits but also a relatively high unsatisfactory rate due to debris/lubricant contamination and the presence of blood. These contaminants clog the TP filter and prevent the deposition of adequate diagnostic cells on the slide. An acetic acid wash (AAW) protocol is often used to lyse red blood cells, before preparing the TP slides. Design: From 23,291 TP cervical cytology specimens over a 4-month period, 2739 underwent AAW protocol due to initial unsatisfactory smear (UNS) with scant cellularity due to blood or being grossly bloody. Randomly selected 2739 cervical cytology specimens which did not undergo AAW from the same time period formed the control (non-AAW) group. Cytopathologic interpretations of AAW and non-AAW groups were compared using the Chi-square test. Results: About 94.2% of the 2739 cases which underwent AAW were subsequently satisfactory for evaluation with interpretations of atypical squamous cells of undetermined significance (ASCUS) 4.9% (135), low-grade squamous intraepithelial lesions (LSIL) 3.7% (102), and high-grade squamous intraepithelial lesions (HSIL) 1% (28). From the 2739 control cases, 96.3% were satisfactory with ASCUS 5.5% (151), LSIL 5.1% (139), and HSIL 0.7% (19). The prevalence of ASCUS interpretations was similar (P = 0.33). Although there were 32% more HSIL interpretations in the AAW group (28 in AAW vs. 19 in non-AAW), the difference was statistically insignificant (P = 0.18). AAW category; however, had significantly fewer LSIL interpretations (P = 0.02). The percentage of UNS cases remained higher in the AAW group with statistical significance (P < 0.01). Conclusions: While AAW had a significantly higher percent of UNS interpretations, the protocol was effective in rescuing 94.2% of specimens which otherwise may have been reported unsatisfactory. This improved patient care by avoiding a repeat test. The prevalence of ASCUS and HSIL interpretations between AAW and non-AAW groups were comparable. Though not statistically significant, HSIL interpretations were relatively higher in the AAW group. LSIL interpretations showed lower prevalence in AAW group.

Abstract Background In the past decade, cervical cancer has gone from being the second to the fourth most common cancer in women worldwide, but remains the second most common in developing countries. This cancer is most commonly caused by high-risk types of human papillomavirus (HPV), mainly type 16 (HPV16), which are sexually transmitted. This study aimed to investigate the usefulness of a cyclic synthetic peptide designed from the major L1 capsid protein of HPV16 for detecting anti-HPV16 antibodies. Methods We designed and synthetized a peptide that corresponds to the full sequence of the surface-exposed FG loop. We tested the antigenicity of the linear and the cyclic peptides against HPV16 L1 monoclonal antibodies. We used ELISA to detect anti-peptide antibodies in sera and cervical secretions of 179 Tunisian women, and we applied polymerase chain reaction and direct sequencing methods to detect and genotype HPV DNA. Results Both the linear and the cyclic peptides were recognized by the same neutralizing monoclonal antibodies, but the cyclic peptide was more reactive with human sera. The prevalence of the anti-peptide antibodies in sera was higher in women with low-grade squamous intraepithelial lesions (LGSIL) than in women with high-grade squamous intraepithelial lesions (HGSIL) (44% and 15%, respectively). This contrasts with HPV16 DNA prevalence. Compared to women from the general population, systemic IgG prevalence was significantly higher among sex workers (25%; P=0.002) and women with LGSIL (44%; P=0.001). In addition, systemic IgA and cervical IgG prevalence was higher among sex workers only (p=0.002 and P=0.001 respectively). We did not observe anti-peptide IgG antibodies in women with a current HPV16 infection.Conclusion Anti-peptide IgG in sera or in cervical secretions could be markers of an effective natural immunization against HPV16. This may open novel perspectives for monitoring vaccinated women and for the design of synthetic peptide-based vaccines.

Abstract Background Anal squamous intraepithelial lesions (ASIL), strongly related to human papilloma virus (HPV) infection, is more prevalent among men who have sex with men (MSM). However, no such data are available for Pakistan yet, and neither HPV vaccination nor anal-cytology screening is implemented in Pakistan. The purpose of this first ever study was to assess the prevalence of HPV-related anal cytological abnormalities among MSM and transgender women living with and without HIV infection in Pakistan. Methods We conducted a cross-sectional study from March 2016 to November 2017 at sexual health centers run by the Perwaaz Trust and the National AIDS Control Program in Karachi. The study enrolled MSM and transgender women aged greater-than-and-equal-to-18-years who reported anal sex in the preceding 6 months. We collected two anal samples for liquid-based cytology and HPV type testing by PCR, and socio-demographic and behavioral data were collected through face-to face interviews. ASIL and its associations with biological and behavioral risk factors were analyzed through Cox regression for prevalence ratios (PR) and corresponding 95% confidence intervals (CIs). Results Out of 271 qualifying participants, 79% were MSM and 21% transgender women. The mean age was 28.8 (± 8) years. Almost 35% (93/271) of the study population had ASIL detected, ASIL was significantly more common among participants living with HIV than in HIV negative ((50/118) 42.4%; vs. (43/153) 28.1%) (p ≤ 0.001). Among ASIL, 66% (61/93) had low-grade squamous intraepithelial lesions (LSIL), and 3.6% (3/93) had high-grade squamous intraepithelial lesions (HSIL). The overall, HPV16 positivity was 35.5% (33/93) among all abnormal anal lesions and all 3 HSIL were HPV16 positive, however, HPV16 positivity could show its association with ASIL detection in univariate model only (PRcrude: 2.11(1.39–3.18)). Moreover, any HR-HPV type (PR 3.04; 95% CI 1.75–5.26), concurrent sexually transmitted infection (STI) (2.13; (1.28–3.55)) and HIV + /HPV + coinfection (1.75; (1.07–2.88)) remained independently associated with ASIL in the multivariate model. Conclusions Abnormal anal cytology among MSM and transgender is prevalent enough to consider optimal screening regimens. Further studies are required to see if periodic anal cytology can be made part of HIV care and treatment programs among MSM in Pakistan.

ObjectivesThis study aimed to assess the relationship between infection with multiple human papillomavirus (HPV) types and abnormal anal cytology in HIV-infected men.DesignAn observational, cross-sectional study.SettingA regional referral hospital in Taiwan.ParticipantsIn total, 714 HIV-infected men were enrolled between March 2011 and June 2016. Thin preparation anal Pap smears were interpreted according to the 2001 Bethesda System. Thirty-seven types of HPV were detected by reverse line blotting, including 13 oncogenic types and 24 non-oncogenic types.Outcome measuresThe relationship between anal HPV infection and abnormal anal cytology in people of Asian ethnicity and the coverage efficacy in HPV-vaccinated HIV-infected men.ResultsOn anal cytology, 175 (24.5%) subjects had atypical squamous cells of undetermined significance (ASCUS) or higher grades of dysplasia, including 87 (49.7%) with ASCUS, 73 (41.7%) with low-grade squamous intraepithelial lesions (LSILs) and 15 (8.6%) with high-grade squamous intraepithelial lesions (HSILs). A higher proportion of subjects with those without LSIL/HSIL (93.1% vs 67.3%, P<0.0001) had multiple HPV types. The odds of having LSIL/HSIL increased with an increasing number of HPV types: the ORs ranged from 1 for no HPV types to 6.96 (95% CI 2.38 to 20.37) for more than five types (Ptrend<0.0001). Multivariate logistic regression analysis showed a significant association between LSIL/HSIL and the number of HPV genotypes present (OR 1.20; 95% CI 1.02 to 1.42, P<0.05). HPV types covered by the nonavalent HPV vaccine (types 6/11/16/18/31/33/45/52/58) were detected in 70.1% of the patients in this study.ConclusionsThe odds of having anal LSIL/HSIL are approximately seventimes greater in HIV-infected men with than withoutsix or more types of HPV. Multiple HPV types in HIV-infected patients deserves aggressive follow-up, and HPV vaccination programme require scaling up.
