Int Health 2024; 16:240-251. [PMID: 37555353 PMCID: PMC11062198 DOI: 10.1093/inthealth/ihad059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 07/18/2023] [Accepted: 07/24/2023] [Indexed: 08/10/2023] Open
Abstract
Trichomonas vaginalis is a protozoan parasite and probably one of the main causes of adverse birth outcomes. Still, there is a paucity of information regarding the burden of T. vaginalis infection in Iranian women. To address this gap, we conducted a systematic review and meta-analysis of studies on trichomoniasis among females in Iran from January 2000 to January 2023. We searched multiple electronic databases (PubMed, Science Direct, Scopus, ProQuest, Web of Science, Google Scholar, Scientific Information Database, Iran Medex, Magiran and Iran Doc) and identified 108 articles with a total of 200 728 women. Using a random effects model, we found a pooled prevalence of 4.30% (95% CI 3.23 to 5.52%). Subgroup analysis, also, demonstrated a statistically significant association between the T. vaginalis prevalence in Iranian women, and the age range, city, sample type, being in prison, sex working and symptomatic infections. Our findings provide important information for healthcare authorities and can inform prevention strategies against trichomoniasis in Iran.

Abstract
These guidelines for the treatment of persons who have or are at risk for
sexually transmitted infections (STIs) were updated by CDC after consultation
with professionals knowledgeable in the field of STIs who met in Atlanta,
Georgia, June 11–14, 2019. The information in this report updates the
2015 guidelines. These guidelines discuss 1) updated recommendations for
treatment of Neisseria gonorrhoeae, Chlamydia trachomatis,
and Trichomonas vaginalis; 2) addition of
metronidazole to the recommended treatment regimen for pelvic inflammatory
disease; 3) alternative treatment options for bacterial vaginosis; 4) management
of Mycoplasma genitalium; 5) human papillomavirus vaccine
recommendations and counseling messages; 6) expanded risk factors for syphilis
testing among pregnant women; 7) one-time testing for hepatitis C infection; 8)
evaluation of men who have sex with men after sexual assault; and 9) two-step
testing for serologic diagnosis of genital herpes simplex virus. Physicians and
other health care providers can use these guidelines to assist in prevention and
treatment of STIs.

Health outcomes associated with crack-cocaine use: Systematic review and meta-analyses. Drug Alcohol Depend 2017; 180:401-416. [PMID: 28982092 DOI: 10.1016/j.drugalcdep.2017.08.036] [Citation(s) in RCA: 90] [Impact Index Per Article: 12.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2017] [Revised: 08/29/2017] [Accepted: 08/29/2017] [Indexed: 12/17/2022]
Abstract
BACKGROUND Crack-cocaine use is prevalent largely in socio-economically marginalized populations in the Americas. Its use has been associated with diverse health outcomes, yet no recent or systematic reviews of these exist. METHODS A systematic review of health outcomes associated with crack-cocaine use was performed, using MEDLINE, Scopus, Web of Science, CINAHL, PsycINFO, and LILACS up to October 2016. Search terms included crack-cocaine and health outcome-related keywords, targeting peer-reviewed studies on quantified health outcomes associated with crack-cocaine use. Random effects meta-analyses produced pooled odds ratios. Levels of evidence for major results were assessed using the GRADE approach. A review protocol was registered with PROSPERO (CRD42016035486). RESULTS Of 4700 articles returned, 302 met eligibility criteria, reporting on health outcomes for 14 of 22 ICD-10 chapters. Conclusive evidence and meta-analyses showed positive associations between crack-cocaine use and blood/sexually transmitted diseases (HIV and hepatitis C virus, others); moderate evidence and meta-analyses supported associations with neonatal health, and violence. There were mixed associations for mental and other health outcomes, yet insufficient evidence to perform meta-analyses for many categories (e.g., mortality). Most underlying research was of limited or poor quality, with crack-cocaine commonly assessed as a secondary covariate. CONCLUSIONS Crack-cocaine use was associated with a range of health outcomes, although it was unclear if there was direct causal impact, interactions between risk factors, or external drivers of both crack-cocaine use and outcomes. Rigorous epidemiological studies are needed to systematically assess health outcomes of crack-cocaine use and underlying pathways, also to inform evidence-based interventions.

Abstract
Trichomonas vaginalis is the most prevalent nonviral sexually transmitted infection, affecting an estimated 3.7 million women and men in the United States. Health disparities are prominent in the epidemiology of this infection, which affects 11% of women aged ≥40 years and a disproportionately high percentage of black women. Particularly high prevalences have been identified among sexually transmitted disease (STD) clinic patients and incarcerated individuals. This article reviews and updates scientific evidence in key topic areas used for the development of the 2015 STD Treatment Guidelines published by the Centers for Disease Control and Prevention. Current evidence is presented regarding conditions associated with Trichomonas vaginalis infection, including human immunodeficiency virus (HIV) and pregnancy complications such as preterm birth. Nucleic acid amplification tests and point-of-care tests are newly available diagnostic methods that can be conducted on a variety of specimens, potentially allowing highly sensitive testing and screening of both women and men at risk for infection. Usually, trichomoniasis can be cured with single-dose therapy of an appropriate nitroimidazole antibiotic, but women who are also infected with HIV should receive therapy for 7 days. Antimicrobial resistance is an emerging concern.

Abstract
Objective. There is a large variation in the prevalence of Trichomonas vaginalis (TV) between different countries and between racial groups within countries. Sexual partner concurrency may play a role. We investigate the correlation between the prevalence of sexual partner concurrency and TV prevalence. Methods. Spearman's correlation to assess relationship between TV prevalence in women and point prevalence of concurrency in men in (1) 11 countries with comparable data (concurrency data from WHO Survey and TV prevalence data from Global Burden of Disease estimates) and (2) three racial groups in the United States (Add Health Study). Results. The prevalence of TV and concurrency was positively correlated in the international (rho = 0.84, P = 0.001) and USA study (rho = 1.0, P < 0.001). Conclusion. Prospective longitudinal studies that include measures of partner behavior are required to definitively establish the role of concurrency in the spread of TV.

Abstract
Trichomonas vaginalis is the most common nonviral sexually transmitted infection (STI) in the world. It was once thought to be a nuisance STI, but it is now being recognized as an important source of reproductive morbidity and a facilitator of HIV transmission and acquisition, and thus it is an important public health problem. The prevalence of T. vaginalis varies greatly by geography and risk group, but is more common among persons of African descent and appears to increase with age, though this may be a screening phenomenon. Wet mount and culture are simple diagnostics, but have lower sensitivity than nucleic acid amplification techniques presently approved for women only. Single dose (2 g) metronidazole (MTZ) for both the index patient and their sexual partners is the preferred treatment. High rates of retest positivity are found after single-dose treatment which are likely due to clinical resistance rather than re-infection and/or drug resistance.

Abstract
Trichomonas vaginalis (T. vaginalis) is one of the main causes of vaginitis, prostatitis, and cervicitis all over the world. Little information is available regarding the burden of T. vaginalis infection in Iranian women. This systematic review and meta-analysis were carried out to determine the prevalence of T. vaginalis among general population of Iranian women. Data were systematically collected from 1992 to 2012 in Iran on such electronic databases as PubMed, Google Scholar, Science Direct, Scopus, Web of Science, Magiran, Irandoc, Iran medex, Scientific Information Database (SID), Global Health, and LILACS. Additionally, abstracts of national scientific congresses and dissertations were included. A total of 30 articles attempted to examine 70,373 individuals and reported the prevalence of trichomoniasis from different regions of Iran. The overall prevalence rate of trichomoniasis in Iran was estimated to be 8% (95% confidence interval (CI) = 0.07 to 0.09) with the maximum 38.8% (95% CI = 0.036 to 0.042) and the minimum 0.009% (95% CI = 0.008 to 0.010), respectively. Also, it was found that the prevalence in Central provinces is higher than other ones. In all studies, the average of age was 24.5 with the maximum and the minimum of 45 and 22.5 years old, respectively. The present review revealed that infection rate is relatively high among Iranian women, and risk factors such as hygienic situation, behavior and local culture, poor socioeconomic condition, feeble moral considerations, and increase in marriage age must be considered in the management of controlling programs.

Abstract
OBJECTIVE A service evaluation of the new Gen-Probe APTIMA nucleic acid amplification test was performed to determine the prevalence of Trichomonas vaginalis (TV) infection in a UK sexual health clinic and identify risk factors to inform an appropriate TV screening strategy. METHOD Unselected patients presenting with a new clinical episode were offered TV testing with Gen Probe transcription-mediated amplification (TV TMA) in addition to routine sexually transmitted infection screening. Asymptomatic females provided a self-collected vulvovaginal specimen and asymptomatic men a first-void urine sample. Symptomatic patients were examined and a urethral swab taken from men and two posterior vaginal swabs from females; one for culture and one for TV TMA testing. Demographic and clinical data were collected on all patients positive for TV infection and 100 randomly selected TV-negative controls. RESULTS 3503 patients underwent TV TMA testing during the evaluation period. The prevalence of TV infection was 21/1483, 1.4% (95% CI 0.9% to 2.2%) in men and 72/2020, 3.6% (95% CI 2.8% to 4.5%) in women. The rate of TV positivity was higher in Black Caribbean patients compared with Caucasian patients (men 5.4% vs 0.1%, p<0.001; women 9.0% vs 1.2%, p<0.001). TV TMA detected an additional 16 infections (38%) in symptomatic women compared with culture. CONCLUSIONS While screening all patients with TV TMA will identify more TV infections, the UK prevalence remains low and this approach is unlikely to be cost effective. In addition to testing symptomatic patients, targeted testing of high-risk asymptomatic groups using TV TMA should be considered.

Abstract
BACKGROUND Complications related to the diagnosis and treatment of Trichomonas vaginalis infection, as well as the association between T. vaginalis infection and increased transmission of and susceptibility to human immunodeficiency virus, highlight the need for alternative interventions. We tested a human-safe, aluminum hydroxide-adjuvanted whole-cell T. vaginalis vaccine for efficacy in a BALB/c mouse model of vaginal infection. METHODS A whole-cell T. vaginalis vaccine was administered subcutaneously to BALB/c mice, using a prime-boost vaccination schedule. CD4(+) T-cell infiltration in the murine vaginal tissue and local and systemic levels of immunoglobulins were measured at time points up to 4 weeks following infection. RESULTS Vaccination reduced the incidence and increased the clearance of T. vaginalis infection and induced both systemic and local humoral immune responses. CD4(+) T cells were detected in vaginal tissues following intravaginal infection with T. vaginalis but were not seen in uninfected mice. The presence of CD4(+) T cells following T. vaginalis infection can potentially increase susceptibility to and transmission of human immunodeficiency virus. CONCLUSIONS The vaccine induces local and systemic immune responses and confers significantly greater protection against vaginal infection than seen in unvaccinated mice (P < .005). These data support the potential for a human vaccine against T. vaginalis infection that could also influence the incidence of human immunodeficiency virus infection.

Abstract
Vaginal infections in pregnancy are associated with considerable discomfort and adverse pregnancy outcomes including preterm delivery, low birth weight and increased infant mortality and also predisposition to HIV/AIDS. This study evaluated the prevalence and factors associated with vulvovaginal candidiasis, trichomoniasis and bacterial vaginosis among women attending antenatal clinic at a hospital in Nigeria. A semi-structured questionnaire was administered and high vaginal swab samples were obtained from consenting pregnant women. The samples were processed following standard protocols. The prevalence of vulvovaginal candidiasis was 36%, while those of trichomoniasis and bacterial vaginosis were 2% and 38%, respectively. Infections were higher in the third trimester and many women admitted to practices that increase risk of these infections. Significant association was found between recent intake of antibiotics and vaginal candidiasis, same association was also found with bacterial vaginosis. Adequate investigation and prompt treatment will reduce the morbidity and attendant effects of these prevalent infections on mother and fetus.

Abstract
BACKGROUND A growing literature has identified associations between impulsivity and negative behaviors such as sexual risk-taking among high-risk and/or vulnerable populations, but few studies have linked impulsivity to biological outcomes of sexual risk-taking. The main purpose of this study was to document associations among impulsivity, sexual risk-taking, and biological measures of sexually transmitted infection (STI+) in a sample of hazardously drinking incarcerated women. METHODS Two hundred forty-five hazardously drinking incarcerated women self-reported alcohol consumption and consequences, impulsivity, and sexual behavior. RESULTS Biological testing revealed a 22.9% prevalence rate for STI+. In this sample, sexual risk-taking fully mediated the association between impulsivity and likelihood of STI+. In addition, individuals reporting sexual activity with multiple partners were significantly more likely to test STI+ than those reporting sexual activity with a primary partner. CONCLUSION These results support previous research on impulsivity by demonstrating that impulsivity leads to STI+ through risky behavioral choices. These findings also extend prior work by documenting this association using biologically confirmed measures in a vulnerable female population that carries multiple risk factors and thus warrants increased research attention.

Abstract
OBJECTIVE Trichomoniasis vaginalis is a risk factor for the acquisition and transmission of HIV. The objective of this study was to determine the prevalence of T vaginalis (using culture) among HIV-infected women receiving gynaecological care at an university HIV clinic in Alabama in addition to predictors of infection. METHODS Electronic medical record review of women presenting to the clinic for gynaecological care during 2006-2012 was performed. Demographic and sexual history data was abstracted in addition to absolute CD4 cell count, HIV-1 viral load and sexually transmitted infection (STI) (including T vaginalis) testing results. Analysis was conducted using Stata V.12. RESULTS T vaginalis was prevalent in 17.4% (83/478) of HIV-infected women; other STIs were less prevalent. Among these women, 384 presented for routine STI screening, of which 12% (46/384) were T vaginalis-infected. Younger age, African-American race, lifetime history of tobacco and drug abuse, lack of HIV therapy, HIV-1 viral load >400 copies/ml, and report of seeking gynaecological care for reasons other than routine STI screening (ie, having symptoms) were significant predictors of T vaginalis in univariate analysis. Age, African American race, and report of seeking gynaecological care for reasons other than routine STI screening remained associated with T vaginalis in multivariable analysis. CONCLUSIONS T vaginalis remains highly prevalent among HIV-infected women, a proportion of which may be asymptomatic. If left undiagnosed and untreated, these women may be more likely to transmit HIV. Increased emphasis on screening for high risk sexual behaviours, testing for T vaginalis, and risk reduction counselling is necessary for all HIV-infected women.

Abstract
Incarcerated women are at high risk for sexually transmitted infections. Left untreated, these infections can have severe adverse health effects. In this study the authors present prevalence rates of trichomonas, chlamydia, and gonorrhea, and factors related to having a sexually transmitted infection in a sample of 245 hazardously-drinking incarcerated women who reported heterosexual intercourse in the previous 3 months. Vaginal swabs were collected following the self-report baseline assessment. Participants averaged 34.0 (±8.8) years of age; 174 (71.3%) were non-Hispanic Caucasian, 47 (19.3%) were African-American, 17 (7.0%) were Hispanic, and 6 (2.5%) were of other racial or ethnic origins. Twenty-three percent of participants tested positive for chlamydia, trichomonas, or gonorrhea. Being African-American, more frequent sex with a casual partner, and reporting more than one male partner were significantly positively related to sexually transmitted infection, while more frequent sex with a main partner was inversely related. Due to the high rates of infection in this population, jail admission provides a public health opportunity to access a concentrated group of sexually transmitted infectious women. Sexually transmitted infection testing targeted at specific demographic factors, for instance younger age, will miss infected women. Risky sexual partnerships, as well as the benefit of maintaining stable main partnerships may be important topics during sexually transmitted infection prevention interventions.

Abstract
BACKGROUND The prevalence of Trichomonas vaginalis is higher among incarcerated women than in the general community. We sought to determine whether a history of incarceration itself was independently associated with trichomoniasis. METHODS The HIV Epidemiology Research Study is a prospective cohort study of 871 HIV-seropositive and 439 high-risk seronegative women in 4 urban centers (Bronx, NY; Detroit, MI; Providence, RI; Baltimore, MD). All participants enrolled between April 1993 and January 1995, with interviews and physical examinations conducted at baseline and at follow-up visits every 6 months up to 7 years. RESULTS Of 1310 subjects, 427 (33%) reported being incarcerated on at least one occasion. In addition, 724 (55%) were found to have a sexually transmitted infection on at least one occasion during the study; baseline rates were 21% for T. vaginalis, 4.3% for Chlamydia trachomatis, 0.6% for N. gonorrhea, and 8% for syphilis. Incarceration was associated with the detection of trichomonas infection (between-subject, odds ratio, 2.4; 95% confidence interval: 1.85-3.14; P < 0.01 and within-subject, odds ratio, 1.56; 95% confidence interval: 1.26-1.92; P < 0.01). The association with incarceration remained significant after adjusting for age, race, HIV status, enrollment risk group, number of sexual partners, marital status, education, bacterial vaginosis, vaginal candidiasis, drug use (crack, cocaine, heroin), alcohol use, health insurance, receipt of public assistance, employment status, visit number, and study site. CONCLUSIONS A history of incarceration was independently associated with the detection of trichomonas infection in a cohort of high-risk women. These data have implications for increased sexually transmitted infection prevention, screening, and treatment upon entry to jail as well as in the communities most affected by incarceration.

Abstract
BACKGROUND Trichomonas vaginalis is a sexually transmitted infection, which is largely underestimated because of ineffective screening protocols and lack of public health attention. METHODS Two studies were conducted to assess the frequency of missed diagnosis of T. vaginalis when using current routine practices for T. vaginalis screening in high-risk female populations. The first study compares the rate of positivity detected using wet preparation microscopy to the number of cases found using polymerase chain reaction (PCR) using residual samples from women attending a public health sexually transmitted disease clinic. The second study compares universal to targeted screening of symptomatic women using PCR on vaginal samples from women screened for sexually transmitted disease at a correctional facility. RESULTS In the first study, a 5-fold increased incidence of T. vaginalis infection was detected when PCR was performed instead of wet mount microscopy in a sample of 222 women screened at a sexually transmitted disease clinic. The second study detected a 5-fold increase in cases among a sample of 471 incarcerated women when universal screening was implemented. CONCLUSIONS Improving detection of T. vaginalis is critical, given that when left untreated, T. vaginalis increases susceptibility to coinfections including human immunodeficiency virus. Changing screening protocols to use improved diagnostic tools and applying universal screening resulted in increased case finding for T. vaginalis among high-risk women. The prevalence of T. vaginalis coupled with its negative impact on health necessitate greater public health attention is needed in order to reduce incidence rates, improve diagnosis, and to better understand this important, yet underestimated, pathogen.

Abstract
INTRODUCTION AND BACKGROUND At the time of incarceration, women have a high prevalence of sexually transmitted infections (STI). In the months after community release, women remain at high risk for new infections. This study assessed the rates and predictors of incident chlamydia, gonorrhea, and trichomoniasis in a sample of hazardously drinking women after incarceration. METHODS Self-reported behavioral data were collected from 245 incarcerated women. Vaginal swabs were collected at baseline, and 3- and 6-month time points and tested for chlamydia, gonorrhea, and trichomoniasis. Treatment was provided for all positive tests. RESULTS Participants' mean age was 34.1 years of age; 175 (71.4%) were Caucasian, 47 (19.2%) were African American, 17 (6.9%) were Hispanic, and 6 (2.4%) were of other ethnic origins. The STI incidence rate was estimated to be 30.5 (95% confidence interval, 21.3-43.5) new infections per 100 person-years. Number of male sex partners reported during follow-up was a significant (z = 2.16; p = .03) predictor of STI; each additional male sex partner increased the estimated hazard of STI by 1.26. CONCLUSION Incarcerated women who are hazardous drinkers are at high risk for STI in the months after their return to the community. In addition to testing and treatment during incarceration, post-release rescreening, education, partner treatment, and follow-up are recommended.

Abstract
OBJECTIVES People who are incarcerated exhibit high rates of disease, but data evaluating the delivery of medical services to inmates are sparse, particularly for jail settings. We sought to characterize the primary medical care providers for county jail inmates in New York State. METHODS From 2007 through 2009, we collected data on types of medical care providers for jail inmates in all New York State counties. We obtained data from state monitoring programs and e-mail questionnaires sent to county departments of health. RESULTS In counties outside New York City (n = 57), jail medical care was delivered by local providers in 40 counties (70%), correctional medical corporations in 8 counties (14%), and public providers in 9 counties (16%). In New York City, 90% of inmates received medical care from a correctional medical corporation. Larger, urban jails, with a greater proportion of Black and Hispanic inmates, tended to use public hospitals or correctional medical corporations as health care vendors. CONCLUSIONS Jail medical services in New York State were heterogeneous and decentralized, provided mostly by local physician practices and correctional medical corporations. There was limited state oversight and coordination of county jail medical care.

Abstract
During the 1990s, some of the highest rates of HIV infection in the United States were found among inmates in the New York City jail and prisons systems. This article traces the history of drug use and HIV infection among populations incarcerated in New York City jails and New York State prisons between 1980 and 2007. It describes and analyzes the policies and programs that were initiated to respond to these epidemics and assesses the lessons learned from almost three decades of experience with HIV among populations in New York's correctional facilities.

Abstract
BACKGROUND Trichomonas vaginalis infection is the most common curable sexually transmissible infection (STI) worldwide. The present study describes the burden and correlates of T. vaginalis infection among young reproductive age women in Mysore, India. METHODS Between November 2005 and March 2006, sexually active women aged 15-30 years were recruited from low-income peri-urban and rural neighbourhoods of Mysore, India. Participants were interviewed and offered a physical examination and testing for T. vaginalis, bacterial vaginosis, vaginal candidiasis, Neisseria gonorrheoea and herpes simplex virus type-2 antibodies. RESULTS Of the 898 participating women, 76 had a T. vaginalis infection (8.5%, 95% confidence interval [95% CI]: 6.7-10.5%). Nearly all (98%) participants were married and most reported their spouse as their main sex partner. The mean age at marriage was 16.9 years (s.d. 2.9 years) and two-thirds of the sample reported having first sexual intercourse before the age of 19 years. Risk factors independently associated with T. vaginalis infection included early age at first intercourse (adjusted odds ratio [OR] 2.09; 95% CI: 1.09-4.00), concurrent bacterial vaginosis (OR 8.21; 95% CI: 4.30-15.66), vaginal candidiasis (OR 2.40; 95% CI: 1.48-3.89) and herpes simplex virus type-2 infection (OR 3.44; 95% CI: 1.97-6.02). CONCLUSION The burden of T. vaginalis infection at 8.5% is relatively high among a community sample of young reproductive aged women. Because this infection increases the risk of HIV transmission and is associated with adverse pregnancy outcomes, there is a need for increased screening and treatment of this easily curable sexually transmissible infection in India.

Abstract
BACKGROUND To estimate the association between Trichomonas vaginalis infection (TV) and 6 sexually transmitted infections: chlamydia, gonorrhea, herpes simplex virus (Types 1 and 2), syphilis, and human immunodeficiency virus (HIV) in a nationally representative sample. METHODS We used data from the National Health and Nutrition Examination Survey combining the 2001-2002 and 2003-2004 waves to estimate the association between TV and sexually transmitted infections (STIs) among women in the civilian, noninstitutionalized US population. The final sample included data from 3648 women, which when weighted, represents the experience of 65,563,298 US women between the ages of 14 and 49. Crude and adjusted relative risks were estimated using logistic regression for rare STIs (<10%; chlamydia, syphilis, and HIV) and Poisson regression for common STIs (herpes simplex virus [HSV] Types 1 and 2). Statistical analyses were conducted using Stata (version 9.2). RESULTS The prevalence of trichomoniasis was 3.2% with over 80% of cases asymptomatic in the past month. All STIs examined (chlamydia, gonorrhea, HSV-1, HSV-2, syphilis, and HIV) were more common among women with a positive test for trichomoniasis. HSV-1 (RR = 1.20, 95% CI: 1.09, 1.34) and HSV-2 (RR = 1.51, 95% CI: 2.32, 3.23) were significantly associated with trichomoniasis after adjusting for race/ethnicity, age, and recent sexual partners. In crude analyses, a positive treponemal test was 6 times (95% CI: 2.07, 18.8) more common and HIV was 13 times (95% CI: 2.88, 59.1) more common among women with trichomoniasis, but these estimates were greatly attenuated after adjustment for potential confounders. CONCLUSION Trichomoniasis is significantly associated with concurrent STI.

Abstract
Trichomonas vaginalis has long been recognized as one of the most prevalent sexually transmitted infections. However, it is only in recent years that it has been appreciated that Trichomonas may play a critical role in amplifying human immunodeficiency virus (HIV) transmission. Given the evidence that T. vaginalis likely promotes HIV infection, the apparent high level of Trichomonas infection in the African-American community is cause for concern. Even if T. vaginalis increases the risk of HIV transmission by a small or modest amount, it translates into a sizable population effect since Trichomonas is so common in this community. Therefore, control of trichomoniasis may represent an important avenue of control for the prevention of HIV transmission, particularly among African-Americans.

Abstract
A total of 544 women outpatients comprising 320 and 224 from Lagos University Teaching Hospital (LUTH), Idi-Araba, Lagos and Military Hospital, Yaba, Lagos, respectively, were examined for Trichomonas vaginalis infection. Both wet mount microscopy and Giemsa staining technique were used. A prevalence of 3.3% was recorded from the 544 women using both methods, 5.4% in the Military Hospital and 1.9% from LUTH. The difference in prevalence was statistically significant using Chi-square test analysis (p<0.05). Age group 21-30 years had the highest prevalence of 1.8%; A higher prevalence of 2.9% was recorded among married women compared to 0.4% prevalence in unmarried women. About one-fifth of the infected individuals were asymptomatic. Symptomatic patients had characteristic symptoms such as greenish yellow vaginal discharge (33.3%), itching/pruritus (22.2%) and malodorous discharge (11.1%) Water system toilet users had the highest prevalence of T. vaginalis infection compared to others using different types of toilet facilities. About 1% of T. vaginalis infection were mixed with Candida albicans. Single infections of Candida albicans was recorded in 33.6% of the total population examined. Sexual promiscuity, age and socio-economic status were important contributory factors in the pattern of infection amongst studied population.

Abstract
Trichomoniasis is a significant sexually transmitted disease (STD) in the spectrum of public health and primary care because of its association with agents such as human immunodeficiency virus and Neisseria gonorrhoeae. However, its true significance may be underestimated due to diagnostic modalities that exhibit poor sensitivity. A total of 1,086 genital specimens from two urban emergency departments, a suburban urgent-care facility, and a metropolitan outpatient physician group were subjected to transcription-mediated amplification-based Trichomonas vaginalis analyte-specific-reagent (ASR) testing (Gen-Probe, Inc.). The rate of positive molecular ASR results (14.5%) doubled that of direct saline preparation (7.0%; P < 0.0002). Analogous increases were observed at one emergency department and within the outpatient physician group (P < 0.0002). No significant increase in the rate of positive molecular ASR results was observed from the facilities that encountered a lower frequency of black/African American patients. While positive T. vaginalis findings via direct saline preparation did not have a significant association with concomitant Chlamydia trachomatis or N. gonorrhoeae infection overall, a positive T. vaginalis ASR result was a better predictor of concomitant C. trachomatis or N. gonorrhoeae infection (odds ratios of 2.34 and 4.46, respectively; P < 0.0001). The increased rate of positive T. vaginalis ASR results was observed in both point-of-care (P = 0.02 versus direct saline preparation) and laboratory (P = 0.003) testing. Highly sensitive T. vaginalis molecular ASR not only transcends issues of specimen integrity and microscopic acumen but also has an increased ability to predict the likelihood of additional STDs in defined populations.

Abstract
BACKGROUND To investigate the temporal associations between Trichomonas vaginalis (TV) diagnoses in women at a large urban sexual health clinic and a major Papanicolaou (Pap) smear screening laboratory in Victoria, Australia with Pap smear screening rates and the introduction of nitroimidazole treatments. METHODS An ecological analysis of TV diagnosis rates at the Melbourne Sexual Health Centre and the Victorian Cytology Service, Pap smear screening rates and nitroimidazole prescription data. RESULTS Diagnoses of TV at the Melbourne Sexual Health Centre peaked in the 1950s at 20% to 30% and then rapidly declined through the 1960s and 1970s to below 1% in 1990. A similar pattern was observed at the Victorian Cytology Service. Metronidazole prescribing and opportunistic Pap smear screening began in Victoria in the 1960s coinciding with declining TV. The availability of tinidazole in 1976 led to further declines in TV in the late 1970s. A national cervical screening program introduced in 1991 was temporally associated with further declines in TV. CONCLUSIONS Our analyses suggest that the introduction of metronidazole was associated with a large reduction in TV among Victorian women in the 1960s. The subsequent availability of tinidazole and increased Pap smear screening may have contributed to the current low TV prevalence in Victoria.

Abstract
BACKGROUND Trichomoniasis vaginalis, the most prevalent nonviral sexually transmitted infection, is associated with negative reproductive outcomes and increased HIV transmission and may be overrepresented among African Americans. METHODS A total of 135 African American women who used drugs were screened for Trichomonas vaginalis on > or =2 occasions between March 2003 and August 2005. Women were administered a structured questionnaire in a community-based research center, underwent serological testing for human immunodeficiency virus and herpes simplex virus type 2, and were screened for Neisseria gonorrhoeae and Chlamydia trachomatis. RESULTS Fifty-one women (38%) screened positive for T. vaginalis at baseline. Twenty-nine (31%) of 95 women with negative results of baseline tests became infected, for an incidence of 35.1 cases per 100 person-years at risk (95% confidence interval [CI], 23.5-49.0). Prevalent infection was associated with drug use in the past 30 days, and incident infection was associated with sexual behavior in the past 30 days, namely having >1 male sex partner. Women who reported having >1 partner were 4 times as likely as women with fewer partners to acquire T. vaginalis (hazard ratio, 4.3; 95% CI, 2.0-9.4). CONCLUSION T. vaginalis may be endemic in this community of African American women. A control strategy that includes T. vaginalis screening in nonclinical settings and rapid point-of-care testing could contribute to the disruption of transmission of this pathogen.

Abstract
PURPOSE OF REVIEW Trichomonas vaginalis is the most common curable sexually transmitted infection. Despite a number of serious health consequences including facilitation of HIV transmission, pelvic inflammatory disease and adverse outcomes of pregnancy it remains an under-recognized condition. This review aims to update the reader on the global epidemiology and control of T. vaginalis. RECENT FINDINGS The burden of T. vaginalis infection is found in resource-limited settings and high-risk groups in industrialized settings. Utilization of polymerase chain reaction-based diagnostics has enhanced our understanding of the epidemiology of T. vaginalis both at the population level and in sexual partners. High rates of asymptomatic infection in male partners of infected females and subsequent re-infection have significant implications for control programmes. Further studies investigating the role of T. vaginalis in facilitating HIV transmission has highlighted its significance and the need to develop and implement control interventions. SUMMARY Future research to develop cheap, point-of-care diagnostic tests will allow a greater understanding of T. vaginalis epidemiology. In addition, the effect of treatment on outcome of pregnancy and HIV acquisition requires further study. This will in turn facilitate operational studies evaluating optimal control strategies and their impact on the complications of T. vaginalis.

Abstract
BACKGROUND Trichomonas vaginalis causes a common sexually transmitted infection (STI) in women, yet trichomoniasis in male sexual partners is not well recognized. Nucleic acid amplification tests can increase detection of T. vaginalis in men compared with culture. METHODS We conducted a prospective, multicenter study to evaluate T. vaginalis infection among male partners of women with trichomoniasis and factors associated with infection by recruiting patients from 3 public clinics in the United States. Male partners were tested for concordant T. vaginalis infection, defined as a positive urethral culture, urine culture, or urine polymerase chain reaction (PCR) result. A subset of men also provided a semen sample for T. vaginalis culture and PCR. Factors associated with concordant infection were determined from bivariable and multivariable analyses. RESULTS We enrolled 540 women with trichomoniasis (diagnosed using wet mount microscopy and/or culture) and 261 (48.4%) of their male partners. T. vaginalis infection was detected in 177 (71.7%) of 256 male partners (95% confidence interval [CI], 66.0%-77.3%), of whom 136 (77.3%) were asymptomatic. A vaginal pH of >4.5 in a woman was independently associated with infection in the male partner (adjusted odds ratio, 2.5; 95% CI, 1.0-6.3). Younger male age (20-29 and 30-39 years) was also found to be an independent risk factor for concordant trichomoniasis. CONCLUSIONS The majority of male partners of women with trichomoniasis were infected; however, few factors predicted infection. T. vaginalis causes a highly prevalent STI, necessitating vastly improved partner management, application of sensitive nucleic-acid based testing, and better clinical recognition.

Abstract
BACKGROUND AND OBJECTIVES The prevalence of trichomoniasis in the general population of the United States is unknown. This study provides the first population-based prevalence estimates of trichomoniasis among young adults in the United States. METHODS The National Longitudinal Study of Adolescent Health (Add Health) is an ongoing prospective cohort study. In a cross-sectional analysis of Wave III of Add Health (N = 12,449), we determined the prevalence of trichomoniasis using a polymerase chain reaction assay. RESULTS The estimated overall prevalence of trichomoniasis in U.S. young adults was 2.3% (95% confidence interval [CI], 1.8-2.7%). The prevalence was slightly higher among women (2.8%; 95% CI, 2.2-3.6%) than men (1.7%; 95% CI, 1.3-2.2%). The prevalence increased with age and varied by region, with the south having the highest prevalence (2.8%; 95% CI, 2.2-3.5%). The prevalence was highest among black women (10.5%; 95% CI, 8.3-13.3%) and lowest among white women (1.1%; 95% CI, 0.8-1.6%). Among men, the prevalence was highest among Native Americans (4.1%; 95% CI, 0.4-29.3%) and blacks (3.3%; 95% CI, 2.2-4.9%), and lowest among white men (1.3%; 95% CI, 0.9-1.8%). CONCLUSIONS Trichomoniasis is moderately prevalent among the general U.S. population of young adults and disturbingly high among certain racial/ethnic groups.

Wet mount microscopy performs poorly compared with culture; however, universal screening using culture would be cost-prohibitive. GOAL The goal of this study was to develop a predictive model for wet mount-negative women who may benefit from targeted use of culture for T. vaginalis detection. STUDY Women presenting for sexually transmitted disease evaluation were prospectively screened for trichomoniasis using wet mount and culture. Multivariate logistic regression was used to identify predictors of culture-proven trichomoniasis among wet mount-negative women. RESULTS A total of 2194 women were screened for trichomoniasis; overall, the prevalence of T. vaginalis was 17.5%. Three predictors (any drug use, contact to trichomoniasis, and African-American race) provided the most specific model (100%); any 1 predictor, the most sensitive model (97.8%). CONCLUSIONS Given the public health impact of trichomoniasis, we recommend using any 1 of 3 predictors to identify women who would benefit from targeted culture for T. vaginalis.

Abstract
Aside from human papillomavirus, trichomoniasis is the most common sexually transmitted infection in the United States today, yet it has long been regarded as a sexually transmitted infection of minor importance. Medical opinion has traditionally held that it plays little role in health complications in women, and it is rarely seen in men. However, evidence has recently accumulated implicating Trichomonas vaginalis as a contributor to a variety of adverse outcomes among both sexes. Among both women and men, the association of T vaginalis with human immunodeficiency acquisition and transmission has been shown in multiple studies. Among women, trichomoniasis may play a role in development of cervical neoplasia, postoperative infections, and adverse pregnancy outcomes and as a factor in atypical pelvic inflammatory disease and infertility. Among men, trichomoniasis has emerged as a cause of nongonoccocal urethritis and as contributing to male factor infertility. As evidence continues to accumulate, the time has come to increase diagnostic efforts beyond traditional sexually transmitted disease clinic settings.

Abstract
OBJECTIVES To identify psychosocial predictors of Trichomonas vaginalis infection among low income African-American adolescent females living in a high risk urban area of the United States. METHODS Baseline plus 6 and 12 month follow up data collected as part of an HIV prevention intervention trial were utilised. The baseline sample consisted of 522 African-American females, 14-18 years of age. Recruitment sites were located in low income neighbourhoods of Birmingham, Alabama, characterised by high rates of unemployment, substance abuse, violence, teenage pregnancy, and sexually transmitted infections. Self administered vaginal swab specimens were cultured for T vaginalis. Baseline measures collected as part of a self administered survey and face to face interviews were used to predict subsequent infection with T vaginalis at any of the three assessment periods conducted over the span of 1 year. RESULTS At baseline, 12.9% were diagnosed with T vaginalis. At the 6 and 12 month follow ups, T vaginalis was diagnosed in 8.9% and 10.2%, respectively. The strongest multivariate predictor of T vaginalis infection was biologically confirmed marijuana use; those using marijuana were more than six times as likely to test positive for T vaginalis (adjusted odds ratio (AOR) = 6.2, p = 0.0003). Other multivariate predictors were reporting that typical sex partners were at least 5 years older (AOR = 2.6; p = 0.005), reporting sex with non-steady partners (AOR = 1.9; p = 0.02), and history of delinquency (AOR = 1.3; p = 0.02). The odds of testing positive increased by 31% for every one unit increase on a six item scale measure of delinquency. CONCLUSIONS Infection with T vaginalis was common and significant multivariate predictors comprised a constellation of problem behaviours, each of which are potentially amenable to behavioural intervention.

Abstract
OBJECTIVES To describe the epidemiology of Trichomonas vaginalis infection and its association with HIV infection, in women in four African cities with different levels of HIV infection. DESIGN Cross-sectional study, using standardized methods, including a standardized questionnaire and standardized laboratory tests, in four cities in sub-Saharan Africa: two with a high prevalence of HIV infection (Kisumu, Kenya and Ndola, Zambia), and two with a relatively low prevalence of HIV (Cotonou, Benin and Yaoundé, Cameroon). METHODS In each city, a random sample of about 2000 adults aged 15-49 years was taken. Consenting men and women were interviewed about their socio-demographic characteristics and their sexual behaviour, and were tested for HIV, syphilis, herpes simplex virus type 2 (HSV-2), gonorrhoea, chlamydial infection, and (women only) T. vaginalis infection. Risk factor analyses were carried out for trichomoniasis for each city separately. Multivariate analysis, however, was only possible for Yaoundé, Kisumu and Ndola. RESULTS The prevalence of trichomoniasis was significantly higher in the high HIV prevalence cities (29.3% in Kisumu and 34.3% in Ndola) than in Cotonou (3.2%) and Yaoundé (17.6%). Risk of trichomoniasis was increased in women who reported more lifetime sex partners. HIV infection was an independent risk factor for trichomonas infection in Yaoundé [adjusted odds ratio (OR) = 1.8, 95% confidence interval (CI) = 0.9-3.7] and Kisumu (adjusted OR = 1.7, 95% CI = 1.1-2.7), but not in Ndola. A striking finding was the high prevalence (40%) of trichomonas infection in women in Ndola who denied that they had ever had sex. CONCLUSION Trichomoniasis may have played a role in the spread of HIV in sub-Saharan Africa and may be one of the factors explaining the differences in levels of HIV infection between different regions in Africa. The differences in prevalence of trichomoniasis between the four cities remain unexplained, but we lack data on the epidemiology of trichomoniasis in men. More research is required on the interaction between trichomoniasis and HIV infection, the epidemiology of trichomoniasis in men, and trichomonas infections in women who deny sexual activity.

Abstract
Trichomonas vaginalis may be emerging as one of the most important cofactors in amplifying HIV transmission, particularly in African-American communities of the United States. In a person co-infected with HIV, the pathology induced by T. vaginalis infection can increase HIV shedding. Trichomonas infection may also act to expand the portal of entry for HIV in an HIV-negative person. Studies from Africa have suggested that T. vaginalis infection may increase the rate of HIV transmission by approximately twofold. Available data indicate that T. vaginalis is highly prevalent among African-Americans in major urban centers of the United States and is often the most common sexually transmitted infection in black women. Even if T. vaginalis increases the risk of HIV transmission by a small amount, this could translate into an important amplifying effect since Trichomonas is so common. Substantial HIV transmission may be attributable to T. vaginalis in African-American communities of the United States.

Abstract
The maturation of the acquired immunodeficiency syndrome epidemic has now claimed more than 12 million women worldwide, the majority in undeveloped countries where human immunodeficiency virus (HIV) and sexually transmitted infections coexist and interact synergistically. Among HIV-infected women, there is excessive morbidity due to sexually transmitted diseases (STDs) and gynecologic disorders. This review summarizes the expanding understanding of vaginal flora, vaginitis, cervicitis, pelvic inflammatory disease, and genital ulcer disease in HIV-infected women. In addition to the altered clinical course, complications, and management difficulties of STDs, some gynecologic infections may influence HIV transmission as well as the vertical transmission of HIV to the newborn. Finally, severe immunodeficiency allows unusual opportunistic pathogens to invade the upper and lower genital tract. Control and prevention of gynecologic infections in HIV-positive and HIV-negative women are key components to preventing further HIV transmission.

Abstract
OBJECTIVES We evaluated the prevalence of gonorrhea, chlamydia, trichomoniasis, and syphilis in patients entering residential drug treatment. METHODS Data on sexual and substance abuse histories were collected. Participants provided specimens for chlamydia and gonorrhea ligase chain reaction testing. Trichomonas vaginalis culture, and syphilis serologic testing. RESULTS Of 311 patients, crack cocaine use was reported by 67% and multisubstance use was reported by 71%. Sexually transmitted disease (STD) risk behaviors were common. The prevalence of infection was as follows: Chlamydia trachomatis, 2.3%; Neisseria gonorrhoeae, 1.6%; trichomoniasis, 43%; and syphilis, 6%. CONCLUSIONS STD counseling and screening may be a useful adjunct to inpatient drug treatment.

Abstract
BACKGROUND Sexually transmitted diseases (STDs) have become an important medical problem in prisons. GOAL To determine the prevalence of and risk factors for STDs among female inmates in a Brazilian prison. STUDY DESIGN All female prisoners at the Espírito Santo State Prison were offered enrollment in this cross-sectional study. An interview exploring demographics, criminal charges, and risk behavior was conducted. Blood and genital specimens were collected for STD testing. RESULTS Of 122 eligible women, 121 (99%) agreed to participate. Prevalence rates were: HIV 9.9%, human T-cell lymphotrophic virus type I 4.1%, hepatitis B virus 7.4%, hepatitis C virus 19%, syphilis 16%, gonorrhea 7.6%, chlamydial infection 11%, human papillomavirus-related cytologic changes 9.3%, trichomoniasis 30%, and bacterial vaginosis 15%. Previous or current drug abuse (54%), injection drug use (11%), and blood transfusion (16%) were associated with at least one STD. Condom use was infrequent. CONCLUSION The prevalence of STDs and of behaviors leading to ongoing transmission are high among female inmates in Vitória, Brazil, and demonstrate the potential importance of prevention activities targeting this population.

Abstract
Trichomonas vaginalis is emerging as a major pathogen of men and women and is associated with serious health consequences. Advances in diagnosis and treatment are presented. The complexity of trichomonad pathogenesis is illustrated in the interaction of this parasite with human cells, tissues and the immune system. It is now becoming evident that the interaction of trichomonads with the host is frequently modulated by environmental signals. The molecular biology of trichomonads is still in its infancy, but analysis of genes, genomic structure and transcriptional mechanisms suggest that trichomonads combine both prokaryotic and eukaryotic features. Evidence for the ancient divergence of trichomonads from other eukaryotic lineages is discussed.

Abstract
BACKGROUND AND OBJECTIVES Female inmates have high rates of sexually transmitted diseases (STDs), and many incarcerated women and jail providers believe STDs are acquired within the jail. We investigated a suspected outbreak of trichomoniasis among female inmates and described the epidemiology of trichomonas infection. GOALS OF THIS STUDY To determine the likelihood of within-jail acquisition of trichomoniasis. STUDY DESIGN Retrospective chart review of gynecologic visits to the jail medical clinic and comparison of trichomoniasis surveillance data over a 6-year time period. RESULTS The minimum prevalence of trichomoniasis infection among 450 female inmates presenting to the medical clinic for gynecologic evaluation was 37%. Most infections were diagnosed early after incarceration, no woman developed a new infection after adequate treatment, and there was no clustering of cases by time or location. CONCLUSION There was no evidence to support within-jail acquisition of trichomoniasis. The high rate of trichomoniasis and other STDs among incarcerated women warrant more comprehensive jail-based STD screening programs.
