Common Risk Factors

Background: In Madagascar, human papillomavirus (HPV), human immunodeficiency virus (HIV), and hepatitis B virus (HBV) infection, as well as syphilis share common risk factors but seem to differ in their prevalence. We measured and compared their prevalence in the country. Methods: The data used in this study came from the Saint Damien Health Centre in Ambanja, Madagascar. The tests used for disease detection were the Alere Determine, Virucheck, rapid plasma reagin, and S-DRY self-HPV samples for HIV infection, HBV infection, syphilis, and HPV infection, respectively. Results: In men and women, respectively, the prevalence was 0.6% and 0.4% for HIV infection, 2.2% and 2.0% for HBV infection, and 0.6% and 0.3% for syphilis. The HPV infection prevalence was 39.3%. Conclusions: Despite common risk factors, the prevalence of HPV infection was high, in contrast to a much lower prevalence of other sexually transmitted infections (STIs) in the same geographical area. Further investigations are required to clarify the status of STIs in the Malagasy population.

Introduction. We have previously determined the prevalence of human papillomavirus (HPV) infection among women in rural Nepal. In the current study, we also wanted to examine the prevalence of and risk factors for other sexually transmitted infections (STIs) in the same population. Methods. Population-based study of nonpregnant women ≥ 15 years who were married or had a history of marriage in the past, residing in five rural villages in Nepal. Data on sociodemographic characteristics, reproductive history, and genitourinary symptoms were collected, and a gynecological examination was conducted. Cervical samples were analyzed by real-time PCR for Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis and HPV, and a serum sample was analyzed for syphilis, hepatitis B virus (HBV) and HIV infection by serology. Results. Of 2416 eligible women, 62% participated. Trichomoniasis, Chlamydia trachomatis infection, HPV and HBV infection, and syphilis were detected in 5.4%, 0.8%, 14.3%, 0.3%, and 0.2% of the women. None had gonorrhea or HIV infection. Of those with genitourinary symptoms, 6.3% had a curable STI. Vaginal discharge classified as abnormal by gynecological examination, but not self-reported discharge, was significantly associated with laboratory diagnosis of a curable STI. Risk factors for trichomoniasis were reproductive age and high cast/ethnicity. Due to low prevalence, risk factors for other STIs could not be disclosed. Conclusion. We observed high prevalence of HPV infection followed by trichomoniasis, while other STIs were rare among women in rural Nepal. There was no association between genitourinary symptoms and laboratory-confirmed STIs.

Objectives: To determine the prevalence and incidence of hepatitis A (HAV) and B (HBV) infection and vaccination in HIV-negative homosexual men in Sydney, and associated risk factors. Methods: An open prospective cohort study was conducted among a community-based sample of HIV-negative homosexual men in Sydney in 2001–02. Participants underwent a face-to-face interview, regarding demographics, sexual behavioural risk factors and sexually transmitted infections, and blood samples were collected. They were followed annually. Results: Nine hundred and three men completed a baseline interview by the end of 2002. Among them, 68% were seropositive to hepatitis A. The seroprevalence of prior hepatitis B infection was 19%, and 53% had serological evidence of HBV vaccination. Younger men were much more likely to be seronegative, with 48% and 46% of <25-year-olds being seronegative to HAV and HBV respectively. In multivariate analysis HAV and HBV infection were associated with increasing age, greater number of lifetime sex partners and HBV infection was also associated with previous sexually transmitted infections. HAV vaccination was associated with increasing age, greater number of lifetime sex partners, overseas travel in the last year and self-reported anogenital warts. HBV vaccination was associated with higher occupational status, greater lifetime number of sex partners and previous sexually transmitted infections. Conclusion: Substantial proportions of gay community attached young homosexual men are still at risk of HAV and HBV infection. This study points to a need for vaccination strategies which ensure high levels of hepatitis A and B immunity in young sexually active gay men.

Epidemiological Characteristics

SUMMARYBy surveying extensive epidemiological behavioural and sexual risk factors in a Korean twin cohort, risk factors for human papillomavirus (HPV) infection were investigated in South Korea. A total of 912 vaginal specimens were collected from the Healthy Twin Study, consisting of twins and their families. A range of epidemiological, behavioural, and sexual activity characteristics were evaluated using multivariate logistic regression analyses of family and twin relationships, adjusted to elucidate the risk factors for HPV infection. Of the various epidemiological characteristics, the possibility of extramarital affairs [odds ratio (OR) 2·48, 95% confidence interval (CI) 1·02–6·02] significantly increased the prevalence of HPV infection. Our multivariate regression analysis indicated that oral contraceptive use (OR 40·64, 95% CI 0·99–1670·7) and history of sexually transmitted disease (OR 2·56, 95% CI 0·93–7·10) were strongly associated with an increase in HPV infection. On the other hand, more frequent vaginal douching (OR 0·32, 95% CI 0·13–0·77) significantly decreased the prevalence of HPV infection. Our results suggested that HPV infection is associated with both biological and behavioural factors.

SUMMARYFor studies examining risk factors of sexually transmitted infections (STIs), confounding can stem from characteristics of partners of study subjects, and persist after adjustment for the subjects’ individual-level characteristics. Two conditions that can result in confounding by the subjects’ partners are: (C1) partner choice is assortative by the risk factor examined and, (C2) sexual activity is associated with the risk factor. The objective of this paper is to illustrate the potential impact of the assortativity bias in studies examining STI risk factors, using smoking and human papillomavirus (HPV) as an example. We developed an HPV transmission-dynamic mathematical model in which we nested a cross-sectional study assessing the smoking–HPV association. In our base case, we assumed (1) no effect of smoking on HPV, and (2) conditions C1–C2 hold for smoking (based on empirical data). The assortativity bias caused an overestimation of the odds ratio (OR) in the simulated study after perfect adjustment for the subjects’ individual-level characteristics (adjusted OR 1·51 instead of 1·00). The bias was amplified by a lower basic reproductive number (R0), greater mixing assortativity and stronger association of smoking with sexual activity. Adjustment for characteristics of partners is needed to mitigate assortativity bias.

Human papillomavirus (HPV) infection is one of the most common sexually transmitted infections. HPV high risk (HPVHR) were HPV16,18 related with invasive penile carcinomas, and HPV low risk (HPVLR) were HPV6,11 related to anogenital warts. Male infection is usually asymptomatic that it would be explain increasing the incidence of HPV associated cancers. Identification HPV genotype is very important for predicting the development of the diseases, to be benign or malignant cancer. The objective of this study was to identify the genotype of HPV that infect men with anogential warts. This research used 12 biopsy specimens from men patient with anogenital warts at Outpatient clinic of Department Dermatology and Venereology, Dr. Soetomo General Hospital period 2016-2017. The specimens were diagnozed by pathologist and HPV gentoyping was done to detect 40 HPV genotype including HPVHR and HPVLR. The result showed that 58% (7/12) were positive for HPVLR and 42% (5/12) were positive for HPV LR/HR. The genotype HPV that infected men patient with anogenital warts is HPVLR (HPV6,11) and HPVHR (HPV18,51,52,82) with single infection of HPVLR or mutiple infection HPVLR/LR or HPVLR/HR. The infection of HPVHR would be develops to be malignant transformation. It suggested that HPV genotype needs to be checked the for the anogenital warts cases for predicting the development of the diseases.

Hiv Serostatus

Risk factors for cervical infection with human papillomavirus (HPV) were assessed among 236 Italian women at risk for human immunodeficiency virus (HIV) infection (intravenous drug users (IVDU) or sexual partners of males at risk for HIV infection). All study participants underwent a structured interview, determination of HIV serostatus and detection of HPV cervical infection by means of polymerase chain reaction (PCR). Overall, the cervical presence of HPV DNA was ascertained in 86 of these 236 women (36·4%), while squamous intraepithelial lesions (SIL) were diagnosed in 57 (24·1%). HPV-infected and non-infected women did not differ in age, education and cigarette smoking. A statistically significant trend in the risk of HPV infection with increasing number of lifetime sexual partners was noted (P=0·01), but such trend was attenuated in multivariate analysis (multiple logistic regression (MLR) odds ratio (OR) for [ges ]20 partners vs 1=1·6, 95% confidence intervals (CI): 0·4–5·9). A nearly threefold higher risk of HPV cervical infection emerged among IVDU women (MLR–OR: 2·7, 95% CI: 1·4–5·0), and this difference was not influenced by HIV serostatus. The prevalence of HIV infection was higher among HPV-positive than HPV-negative women (62·8% and 54·0%, respectively) (MLR–OR=1·9, 95% CI: 0·9–3·8), and the proportion of women with less than 200 CD4+ cells/mm3 was slightly and not significantly higher among HPV-positive (47·1%) than negative women (37·2%).
