Prevalence and predictors of sexually transmitted infection among newly incarcerated females

OBJECTIVES: To examine demographic and behavioral characteristics in incarcerated women to determine which characteristics are associated with prevalent sexually transmitted infections (STIs). STUDY DESIGN: A cross-sectional analysis of data of 205 women entering jail in Rhode Island was performed as part of a study evaluating a family planning program. Women were recruited near time of commitment, and inclusion was limited to women at risk for an unplanned pregnancy. Incarcerated women were interviewed by a research assistant for demographic information, psychosocial and behavioral characteristics. Self-collected vaginal swabs were tested for STIs, including Neisseria gonorrhoeae and Chlamydia trachomatis by polymerase chain reaction and Trichomonas vaginalis by InPouch culture. Relative risks (RRs) were estimated using Poisson regression. RESULTS: Sixty-eight of 205 patients tested positive for an STI [33%; 95% confidence interval (CI) 27-40%]. Forty-five patients (26%) tested positive for T. vaginalis, 27 (14%) were positive for C. trachomatis, and 21 (11%) were positive for N. gonorrhoeae. On bivariate analysis, 6 or more sexual partners in the last year (RR 1.84; 95% CI 1.01-3.36), exchanging sex for drugs/money (RR 1.65; 95% CI 1.01-2.69), and homelessness (RR 1.82; 95% CI 1.07-3.09) were associated with STI. After adjustment for age, race/ethnicity, education, and other covariates, none of the factors was significantly associated with STI. CONCLUSIONS: The prevalence of STI in this jail population is high. Incarceration represents a unique opportunity to evaluate and treat this underserved population. Predictors of infection are limited and infection is common; therefore, routine screening should be considered in this population.     

Prevalence of sexually transmitted infections among antenatal women in Vanuatu, 1999-2000

BACKGROUND: The epidemiology of sexually transmitted infections (STIs) and HIV in Vanuatu is poorly defined. GOAL: The goal was to determine the prevalence of laboratory-confirmed gonorrhea, chlamydia, trichomoniasis, syphilis seroreactivity, and HIV among pregnant women in Vila, Vanuatu. STUDY DESIGN :A cross-sectional survey of 547 pregnant women attending a first-visit antenatal hospital clinic in Vila. Laboratory testing included polymerase chain reaction on tampons for chlamydia, gonorrhea, and trichomoniasis; testing of sera for syphilis with rapid plasmid reagin; and enzyme-linked immunosorbent assay for HIV. RESULTS: The prevalence of trichomoniasis was 27.5% (150); of chlamydia, 21.5% (117); of gonorrhea, 5.9% (32); and of syphilis, 13 (2.4%). No HIV cases were detected; 214 women (40%) had > or =1 STI. Young age and single marital status were both significantly associated with infection (P < 0.001). CONCLUSION: Chlamydial infection and trichomoniasis are hyperendemic among pregnant women in Vila. Young, single women are at greatest risk for infection.     

Prevalence of sexually transmitted infections among clients of female commercial sex workers in Thailand

BACKGROUND: Clients of commercial sex workers are considered at high risk for the acquisition and transmission of sexually transmitted diseases (STDs). Identification and treatment of infections in this group could help to reduce the transmission of STDs. GOAL: To ascertain the prevalence of sexually transmitted organisms in male clients of female sex workers in Thailand by analysis of seminal fluid collected after intercourse. STUDY DESIGN: Used condoms were collected from 291 male clients attending a brothel in Hat Yai, Thailand during a 7-day period. Nucleic acid was extracted from seminal fluid and tested by polymerase chain reaction for the presence of Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, herpes simplex virus (HSV) and HIV sequences. RESULTS: Overall, 17 (6%), 47 (16%), and 2 (1%) of specimens were positive for C trachomatis, N gonorrhoeae and T vaginalis respectively. HSV sequences were found in 24 (8%) of the specimens: 14 specimens (5%) with HSV type 1, and 11 specimens (4%) with HSV type 2. HIV RNA was detected in two samples (1%). Overall, 75 specimens (26%) were positive for one or more infections, and more than one pathogen was detected in 16 specimens (5%). CONCLUSION: This study reports a high rate of STDs among clients of female sex workers in Thailand. Consequently, this population is a significant risk for transmitting STDs to commercial sex workers and to other noncommercial partners. Strategies that target this population of men are needed to reduce STD and HIV transmission.     

Prevalence of asymptomatic sexually transmitted infections among high-risk patients attending a free anonymous HIV-screening center

INTRODUCTION: The aim of this study was to assess the prevalence of sexually transmitted infections among patients attending an anonymous HIV Screening Center. PATIENTS AND METHODS: This prospective study was performed in the HIV Screening Center of University hospital in Reims (France) from May 1997 to December 1997. The inclusion criteria were the asymptomatic clinical presentation and the presence of risk factors for sexually transmitted infections referring to WHO criteria. The methods included clinical examination after application of acetic acid and urethral and endocervical swabs to identify:Neisseria gonorrhoeae, Chlamydia trachomatis, Ureaplasma urealyticum, Mycoplasma hominis, Gardnerella vaginalis, Trichomonas vaginalis in specific culture. Treponema pallidum and HIV-1 infection were both detected by Enzym Linked Immuno Sorbent Assay (ELISA). RESULTS: One hundred and one patients (62 men and 39 women) were included in the study. Their mean age was 27 +/- 4 Years. Risk factors for sexually transmitted infections were: multiple sexual partners 81 p. 100; homo or bisexuality 16 p. 100; intravenous drug use 3 p. 100. The sexually transmitted infections were: HIV-1 infection 1 p. 100;Ureaplasma urealyticum 25 p. 100; genital warts 5 p. 100;Chlamydia trachomatis 3 p. 100; Gardnerella vaginalis 3 p. 100; Mycoplasma hominis 2 p. 100; Treponema pallidum 0 p. 100; Neisseria gonorrhoeae 0 p. 100; Trichomonas vaginalis 0 p. 100. The prevalence of sexually transmitted infections was significantly higher among women (p<0.05). DISCUSSION: Classical sexually transmitted infections and HIV infection were rarely detected in this study; but prevalence of other sexually transmitted infections (genital warts, Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum) was high. Ureaplasma urealyticum is considered as a possible pathogenic agent in pregnant women (preterm delivery, decrease of birth weight, chorioamniotitis). These results suggest that other than sexually transmitted infections in high risk patients attending a HIV Screening Center other sexually transmitted infections should also be systematically screened for.     

Bacterial sexually transmitted infections

Worldwide, the incidence of bacterial sexually transmitted infections (STIs) has shown a significant increase in recent years. In Germany, this circumstance is reflected by a rise in the number of reported syphilis cases. There has also been an uptick in the incidence of non‐notifiable STIs such as gonorrhea and infections caused by Chlamydia trachomatis and Mycoplasma genitalium. A key factor in the spread of these infections is their varied clinical presentation, which includes urogenital, pharyngeal and rectal involvement as well as a large number of asymptomatic cases. New real‐time multiplex PCR methods allow for rapid and targeted detection of STI pathogens. The most common bacterial STI is urogenital chlamydial infection caused by serovars D–K, which affects young adults in particular. Lymphogranuloma venereum (LGV) caused by L serovars often presents as chlamydial proctitis. In recent years, Neisseria (N.) gonorrhoeae has shown a significant development of resistance, with high‐level monoresistance and multiresistance to antibiotics commonly used for treatment. It is therefore imperative that sensitivity testing of N. gonorrhoeae be performed in addition to nucleic acid amplification tests (NAATs). Increased drug resistance has also been observed for Mycoplasma genitalium, a fact that complicates treatment.     

Prevalence of sexually transmitted infections and high-risk sexual behaviors in heterosexual couples attending sexually transmitted disease clinics in Peru

OBJECTIVES: The objectives of this study were to determine the prevalence of sexually transmitted infection (STIs) in heterosexual couples and the sexual behaviors associated with their acquisition. GOAL: The goal of this study was to better direct educational efforts to decrease STI among heterosexual couples in Lima, Peru. STUDY DESIGN: We conducted a case-control study in 195 heterosexual couples without HIV infection who attended 2 sexually transmitted disease clinics in Lima, Peru. A case was defined as an individual with one or more newly diagnosed STIs such as gonorrhea, chlamydia, trichomoniasis, herpes simplex, syphilis, mycoplasma, or ureaplasma. RESULTS: Thirty-three percent of individuals (41 men and 89 women) had at least one STI and 26 couples (13%) had the same STI detected. Men who have sex with men (MSM) accounted for 13% of all men, had higher rate of STIs and higher risk behaviors than non-MSM. Ureaplasma infection was the most prevalent STI found in both men and women and was associated with oral sexual contact. In heterosexual pairs, condom use during anal sex occurred less than 10% of the time. CONCLUSIONS: The heterosexual couples in sexually transmitted disease clinics have high-risk behaviors and STIs are frequent. The educational effort concerning prevention of STIs requires higher effort.     

New sexually transmitted infections among adolescent girls infected with HIV

OBJECTIVES: Although the prevalence of sexually transmitted infections (STIs) among girls infected with HIV has been reported, the incidence of STI diagnoses has not been well documented. The objectives of this study were to examine (1) incident STI diagnoses and (2) the association between viral load (VL) and incident STI diagnosis among HIV-infected adolescent girls in care. METHODS: This was a prospective longitudinal 18-month study of girls enrolled in the Adolescent HIV trials network. Cox proportional hazard modelling was performed to evaluate the incidence of STI by baseline viral load. RESULTS: The mean (SD) age of participants was 20.6 (2.0) years, viral load of participants was 66,917 (165,942) copies/ml and median viral load was 7,096 copies/ml. The incidence of STIs for the entire cohort was 1.4 per 100 person-months. During the 18-month follow-up period, there were no significant differences in the STI incidence between the high and low viral load groups (hazard ratio (HR) = 0.86, 95% CI 0.37 to 1.95) There was also no significant association between STI incidence and log-transformed viral load (HR = 1.10, 95% CI 0.92 to 1.3). CONCLUSIONS: Adolescent girls with HIV infection continue to acquire sexually transmitted infections after diagnosis. This analysis does not suggest that VL is a critical factor in STI acquisition over time. Additional work exploring the role of other contextual factors on STI acquisition among HIV-infected adolescent girls is warranted.     

Vulvar infections: beyond sexually transmitted infections

The vulva is an under‐studied area of the female genitourinary tract which is prone to maceration, overgrowth of organisms, and atypical presentations of common dermatologic conditions. In current practice, dermatologists must recognize and manage vulvar infections and infestations beyond the more commonly recognized sexually transmitted infections. Herein, this article reviews the literature on a selection of under‐recognized viral, bacterial, fungal, and parasitic vulvar infections and infestations.     

Marital violence and sexually transmitted infections among women in post-revolution Egypt

ObjectivesTo explore the relationship between past year physical or sexual partner violence against women and women’s self-report of sexually transmitted infection (STI) symptoms in post-revolution Egypt; and to examine the effects of men’s and women’s risky sexual behavioural characteristics and structural dimensions of poverty and gender inequality on this relationship.Study designThis study uses the nationally representative cross-sectional demographic and health survey data conducted in 2014. Multivariate logistic regression was used to assess the relationship between past year partner violence and self-report of STI symptoms among currently married women.Main outcome measureswomen’s self-report of STI was based on their responses to three questions; whether in the past year they had: got a disease through sexual contact?, a genital sore or ulcer?, or a bad smelling abnormal genital discharge? Women who gave an affirmative response to one or more of these questions were assumed to self-report STI.ResultsAlmost one-third of women self-reported symptoms of STI. Fourteen percent of women reported they had experienced physical or sexual violence by a male partner in the past 12 months. Abused women had a 2.76 times higher odds of self-reported STI symptoms (95% CI 2.25–3.38). The significant relationship between self-reported STI and past year partner violence against women did not alter when adjusting for men’s and women’s behavioural characteristics and factors related to poverty and gender inequality.ConclusionsPublic health interventions that address women’s sexual and reproductive health need to consider violence response and prevention strategies.     

Pregnancy and sexually transmitted viral infections

Viral infections in pregnancy are a major cause of morbidity and mortality for both mother and fetus. Viral STIs occur as surface infection and then gradually infect immunologically protected sites. Therefore, these are asymptomatic, hidden and hence underdiagnosed, persistent and difficult to treat. HSV, HPV, HBV, HIV and CMV (cytomegalovirus) are the common ones. Most of these are transmitted during intrapartum period. Proper screening, identification and treatment offered during prenatal period may help in preventing their complications. Twenty five percent of women with a history of genital herpes have an outbreak at some point during the last month of pregnancy. Acyclovir is the accepted efficacious and safe therapy for HSV in pregnancy. Globally, HPV infection is the most common sexually transmitted infection. Neonatal transmission can occur in the absence of clinically evident lesions. HPV 6 or 11 may lead to Juvenile Onset Recurrent Respiratory Papillomatosis (JORRP). TCA, liquid nitrogen, laser ablation or electrocautery can be used to treat external genital HPV lesions at any time during pregnancy. Cesarean section is recommended only if the lesions are obstructing the birth canal. Mother to child transmission (MTCT) in HIV accounts for 15-30% during pregnancy and delivery, and a further 5-20% of transmission occurs through breastfeeding. HBV infection during pregnancy does not alter the natural course of the disease. In women who are seropositive for both HBsAg and HBeAg, vertical transmission is approximately 90%. Pregnancy is not a contraindication for HBV vaccination. Cytomegalovirus (CMV) is the most common intrauterine infection. Cytomegalic inclusion disease (CID) is the most severe form of congenital CMV infection. Treatment is supportive.     

Epidemiology of sexually transmitted diseases and infections

Sexually transmitted diseases and infections (STDIs) are known to have a major socioeconomic and biologic impact, par notticularly on women (e.g., sterility, ectopic pregnancies, neo notplasms, etc.) and fetus (intrauterine and perinatal mortality, infection, malformations). Sex work noters do not use health services appropriately and are a high-risk category. Despite this evidence, data on prostitution and STDIs in some countries are limited. Sexual health medicine is involved in the community by identifying and minimizing the STDI problems through laboratory screening, diagnostic testing, education, and research.     

Clustering of seropositivities for sexually transmitted infections

BACKGROUND: Serology for different sexually transmitted infections (STIs) is useful for epidemiologic studies on the spread of STIs in different populations. Studying whether seropositivities for different STIs cluster could be useful, both for development of improved serologic markers of sexual behavior in populations and for understanding how STIs may differ in terms of the dynamics of their spread. GOAL: To evaluate the degree of clustering of different STIs in relation to sexual history. STUDY DESIGN: An age- and sexual history-stratified subsample of 275 women from a survey of healthy Swedish women seeking contraceptive advice was tested for human papillomavirus (HPV) types 6, 11, 16, 18, and 33; Chlamydia trachomatis; herpes simplex virus 2 (HSV-2); and human herpesvirus 8. RESULTS: Significant clustering was observed only for HPV types 6 and 11; for HPV types 16, 18, and 33; and for C trachomatis and HSV-2. The serologic marker that correlated best with lifetime number of sex partners was HPV type 16 (odds ratio [OR], 10.2; 95% CI, 3.8-27.6). The combined serologic marker that correlated most highly with sexual history was joint positivity for HPV types 16 and 33 (OR, 25.5; 95% CI, 5.4-120.4). CONCLUSIONS: The degree of clustering between different STIs varies from nonexistent to strong, implying that different STIs commonly have very different transmission dynamics. Certain combinations of STI serologic tests may be useful in epidemiologic studies for predicting sexual behavior in groups.     

Sexual behavior among adolescent women at high risk for sexually transmitted infections

BACKGROUND: The temporal pattern of partners and sexual encounters may be key factors in the acquisition and transmission of sexually transmitted diseases (STDs). Behavior among adolescent women is of particular interest because they frequently have the highest prevalence and incidence of infection. GOAL: To examine coital diary data collected during a 7-month longitudinal study of young women at high risk of STDs and to describe their sexual behaviors, with particular attention to issues of partner sequence and overlap. STUDY DESIGN: A 7-month longitudinal study of young women infected with or having a sexual contact infected with Neisseria gonorrhoeae, Chlamydia trachomatis, or Trichomonas vaginalis attending the STD clinic or one of four neighborhood adolescent health clinics. Data were collected at enrollment and at 1, 3, 5, and 7-month follow-up visits. Coital diaries were kept between visits. RESULTS: The average frequency of coital events was 0.94 per week. The median number of sexual partners during the follow-up period was one, and overlapping of partnerships was an uncommon occurrence. The number of days between the last coital event of a current relationship and the first encounter of a new relationship differed for those choosing a new partner (mean, 20.6 days) and those who returned to a previous partner (mean, 7.9 days; P < 0.001). CONCLUSION: Although at high risk for STDs, high-risk behavior was not common among the study population. Partner choice and the behavior of these partners may be more important elements than personal high-risk behavior in accounting for the high prevalence of sexually transmitted infections among inner-city adolescent women.
