Trichomonis hiv infection-Trichomoniasis and HIV interactions: a review

Don't miss out! Create your free JWatch. J Infect Dis Mar 1. Although ulcerative and non-ulcerative sexually transmitted infections STIs are generally known to increase the risk for HIV infection, the data on trichomoniasis have been less conclusive. Now, investigators have evaluated this association using data from a prospective study of female commercial sex workers in Mombasa, Kenya.

The United States has a large community supervision population, a growing number of whom are women. Trichomonas vaginalis infection is strongly associated with an increased risk of HIV acquisition and transmission, particularly among women, but there is a paucity of research on HIV and T.

This paper examines the prevalence of T. It also examines the month outcomes of women treated for T. Women received biological tests for HIV and T. Of the women tested for sexually transmitted infections, 77 women HIV-positive women had significantly higher rates of T. Sixteen women 4. Of the 77 women who were positive for T. Of those who received treatment, 17 Given the high prevalence of T. A study of women under community supervision found higher rates of T.

In , an estimated 4. For example, chronic genital chlamydia infection in women can lead to pelvic inflammatory disease PID , infertility and ectopic pregnancy, but reproductive outcomes in men are comparatively minor.

Though often discounted as an infection with few consequences, if left untreated, T. A national profile shows that women in the criminal justice system are typically in their early to mid-thirties. Thus, providing regular screenings and adequate treatment among women under community supervision may be a relatively simple public health solution that could greatly reduce the morbidity of this infection. This paper 1 assesses HIV and T. We used biological STI data from the baseline assessment and the 12 month follow-up interview.

A total of 1, women were screened from community courts and probation sites in New York City. Of these, women completed informed consent and baseline interviews, were randomized into the study arms, and women completed the 12 month assessment.

Data were collected at community supervision sites throughout New York City. Trained staff administered surveys at baseline, and three month, six month and 12 month follow-up periods. All participants provided written informed consent to participate in the study. This study was approved by institutional review boards at Columbia University and the Center for Court Innovation.

At baseline and during each of the follow-up periods, women completed a computer-assisted self-administered interview CASI approximately an hour and a half in length. This interview elicited detailed information on sociodemographic characteristics age, ethnicity, marital status, education level, employment status, monthly income, and location of residency , incarceration history, alcohol and substance use history, sexual behaviors, and sexual partner characteristics.

Women obtained a self-collected vaginal swab during their visit at both the baseline and month follow-up sessions to test for T. Specimens were collected Monday through Thursday and shipped twice weekly on Tuesdays and Thursdays. After the specimens were collected, they were logged and refrigerated immediately. Lab tests were conducted sometime between the same day of arrival up to five days after arrival. Specimens were tested for T. All women who tested positive for an STI were referred by the CRC to a physician for the appropriate treatment and provided the CRC with forms completed by their medical providers to verify treatment.

We followed all women who were infected with T. Descriptive statistics were used to describe the sample. Individuals who had missing data were excluded from the analysis.

Out of women who completed baseline interviews, four were excluded because they did not provide vaginal swabs for STI testing, so women were retained for analysis in this paper. In the chi-square test examining T. Descriptive statistics were conducted to illustrate treatment outcomes of T.

Table 1 provides information on the main demographic characteristics of the sample. The mean age was The majority of women were highly impoverished. Over half The majority of women were single There were no other sociodemographic differences between women who were infected with T.

Baseline prevalence of STI infections are shown in Table 2. The rate of C. Nearly a quarter of participants tested positive for T. Rates of T. Other co-infections included one participant diagnosed with both T. No HIV positive participants were diagnosed with C. Among the 77 women who tested positive for T. Of the 77 women infected with T.

Of those who were treated, over a quarter Of those who were not treated for T. There were no significant differences in treatment outcomes between women who were HIV positive and those who were HIV negative. Among the women not infected with T. We did not find any significant differences in T.

Our findings showed a high rate of T. At the baseline assessment, over a third of HIV-positive women were infected with T. Research has shown that T. Though this paper was not designed to examine the contributing effects of T. Other studies among women involved in the criminal justice system have also found a high prevalence of T.

The vast majority of women in our study had not been previously screened for T. Effective treatment of T. Increased partnerships between public health and criminal justice systems may be one way to expand STI screening and treatment to better reach vulnerable populations.

Though STI testing in community supervision settings is not common, a study from Indianapolis indicated that community court-based STI screening programs can be an effective way to increase STI testing and linkage to care among individuals under community supervision. Consistent with other studies, 27 , 28 our findings indicated that untreated T.

Nearly half of participants in our study who did not receive treatment at baseline were infected with T. The proportion of women who were positive at 12 months was not statistically significantly different among those who were and were not treated at baseline, indicating a need for regular T. Prolonged infection with T. Targeted efforts to increase both may be warranted for this at-risk population. Even after receiving treatment for T.

The source of these repeat infections is unclear. Possible sources of repeat positives after treatment are reinfection from an untreated baseline partner, infection from a new partner, or treatment failure. Though women were encouraged to have their partner screened and treated for T.

It is also possible that some women may have been infected by a new partner. Over half of the women in our study had multiple sex partners. Treatment failure may be another cause of a repeat positive. Treatment of T. The data have a number of limitations that should be considered. First, although we had participants return signed forms from the doctor stating that they were treated for T. Second, we did not re-test women treated for T. Third, although we encouraged women to have their partners screened and treated for T.

Finally, these data were obtained from a convenience sample of drug using women under community supervision in New York City; thus, our findings may not be generalizable to broader populations or community supervision populations in other geographical settings.

Despite a growing body of research demonstrating its importance, T. Without specific screening mandates and targeted funding, T. We appreciate the assistance of the Center for Court Innovation and the New York City Department of Probation for supporting the implementation of this study, and want to particularly thank the women who participated in this study.

Office on Women's Health. However, since condoms don't cover everything, it's still possible to get or spread trichomoniasis even when using a condom. About 70 percent of people with trichomoniasis don't experience any signs or symptoms. The reinfection rate for women can be as high as 17 percent in the three months after treatment. Symptoms usually appear within 5 to 28 days of exposure.

However, its impact as a cofactor for HIV acquisition is poorly understood. Samples from women who experienced HIV seroconversion cases during a longitudinal study involving women in Uganda and Zimbabwe were matched with samples from HIV-uninfected women controls.

For cases, analyzed samples were from the visit in which HIV seroconversion was detected and the visit preceding detection of seroconversion; for controls, one analyzed sample was from the visit matched by follow-up duration to the cases' seroconversion visit, and the other sample was from the visit immediately preceding the matched visit. The prevalence of T. In multivariable analysis controlling for hormonal contraception, other STIs, behavioral, and demographic factors, the adjusted odds ratio for HIV acquisition was 2.

The presence of behavioral risk factors for HIV infection, study recruitment from a referral population at high-risk for HIV, primary sex partner-associated risk for HIV infection, and herpes simplex virus type 2 seropositivity were also predictive of incident HIV infection.

Given the high prevalence of T. Information regarding the prevalence of trichomoniasis vaginalis is scarce because this infection receives only limited public health attention. As a part of this large-scale project aimed at understanding the variation in HIV prevalence in different parts of Africa, a representative sample was enrolled and tested for numerous risk factors, including Trichomonas vaginalis. Using culture to detect trichomonads, the authors of that study described prevalences ranging from 3.

The relationship between T. Biological interactions between T. After receipt of metronidazole treatment by men infected with T. Several epidemiologic studies have attempted to define the effect of nonulcerative STI, including T. However, in a survival analysis of the same data, the authors described an adjusted relative risk of 1. Although only 1 study found a significant association between T.

Similar findings were observed in a meta-analysis performed by Sexton et al. Given the biological plausibility and the mathematical modeling that suggests that T. This may, in part, be attributable to the limitations associated with all studies attempting to define the relationship between the presence of an STI and the susceptibility to HIV infection.

Study design issues are well described elsewhere [ 12 , 13 ] but include case ascertainment bias; lengthy time between follow-up; confounding by sexual behaviors, particularly those of the partner and the sexual network; and lack of external validity, which is attributable to the need to perform studies in high-risk populations, such as FSWs.

Study population and sample collection. Data and samples were from a longitudinal study of hormonal contraception and HIV acquisition in Uganda and Zimbabwe, which has been described in detail elsewhere [ 14 ]. In brief, participants were aged 18—35 years and negative for HIV at enrollment. In Uganda, women were recruited from family planning clinics, and women were enrolled from high-risk referral settings, such as STI clinics or FSW networks. In Zimbabwe, women were enrolled at family planning clinics.

Participants were seen in clinic every 3 months for up to 24 months. Informed consent was obtained from all study participants, and approval for all protocols was obtained from institutional review boards at participating institutions. These women were classified as cases for the nested case-control study described here. Control subjects were matched on the basis of study site, age, a composite STI variable, and length of study follow-up.

The composite STI variable, consisting of C. The composite STI variable was set to 1 if a participant was infected with C. The composite STI variable was set to 0 for women who tested negative for all 3 of these conditions at both visits. Matching was performed on the basis of this variable, both to control for the presence of other sexually transmitted pathogens and to maximize the number of case-control sets that could be included in an analysis of women with no other treatable STI during the period of interest.

Four controls were identified per case and prioritized on the basis of the matching testing criteria; the closest match was priority 1, and the weakest match was priority 4. This allowed us to locate 2 controls per case, assuming that some samples would be missing from the study repository.

Behavioral and risk measures. On the basis of findings of the parent study analyses [ 14 ], composite variables were created for measures that were highly correlated and resulted in collinearity during multivariable modeling. Participant behavioral risk was measured using 3 variables based on behavior during the previous 3 months: having multiple sex partners, having a new sex partner s , and any commercial sex work.

For this analysis, these variables were combined into a composite dichotomous variable. Primary sex partner-associated risk was also measured using a composite variable based on responses to multiple questions in the interview.

These included having a partner with HIV infection, urethral discharge, weight loss, nights spent away from home, or a history of sex with FSW. STI symptoms were restricted to the participant's selfreported symptoms for this analysis. These included abnormal vaginal discharge, vaginal itching, pelvic pain, pain during sex, and irregular bleeding. Responses were combined into a composite variable, as described above.

The exposure of interest for this study was the presence of T. Diagnosis of vaginal infections and STIs. Vaginal swabs were collected in saline for a KOH whiff test and wet mount microscopy to identify yeast buds or pseudohyphae, motile trichomonads, or clue cells.

Bacterial vaginosis was diagnosed on the basis of Amsel criteria. This assay has been described elsewhere [ 16 ]. Following amplification, T. All selected cases with matched controls were included in this analysis. Although the study aimed to have 2 controls per case i. Conditional logistic regression, performed using SAS statistical software SAS Institute , was used for our primary analyses, which did not include the matching variables.

Forward variable selection procedures were used to finalize the regression model. Population characteristics. Samples were available from Twenty-four Cases were matched to women who remained HIV negative through the study follow-up period. The median ages at enrollment were 24 years for the cases and the controls.

The median number of days between the visit during which HIV infection was detected and the last visit during which HIV was not detected was For controls, a median of There were no baseline differences between cases and controls with respect to age, education level, number of pregnancies, STI symptoms or history, or coital frequency. Although microscopy is a useful diagnostic tool in resource-constrained settings, DNA-based diagnostic tests are becoming increasingly available in other settings.

When analysis was restricted to infections identified only by PCR, 5. All but 1 There was no statistical difference in treatment rates between cases and controls. The presence of symptoms in women with T.

Univariate analyses. All further analyses were performed using T. We also examined differences based on the method of diagnosis at the previous visit. Univariate analysis of infection-associated risk factors for human immunodeficiency virus HIV infection present at the visit before serological detection of HIV infection or the equivalent visit for nonseroconverters. The point prevalences of STI and symptoms at the visit before detection of HIV infection were compared among cases and controls table 1.

The presence of STI symptoms was not included in the multivariable modeling because it was considered to be a probable outcome of trichomoniasis vaginalis and would have resulted in overcontrolling. Demographic and behavioral variables that were significantly associated with an increased risk of HIV infection included not living with partner, participant behavioral risk, recruitment setting high-risk referral clinic vs.

Univariate analysis of risk factors for human immunodeficiency virus HIV infection present at the visit before serological detection of HIV infection or the equivalent visit for nonseroconverters. Multivariable analyses. Women who received a diagnosis of T. Other significant factors included a protective effect of living with a partner and an increased risk associated with participant behavioral risk, recruitment setting i.

Although T. In this analysis, T. In fact, the adjusted OR was even higher in this subgroup, suggesting that for women with less risk from sexual networks, infection with T.

Multivariable analysis of risk factors for human immunodeficiency virus HIV infection present at the visit before detection of HIV infection. Use of the same multivariable model, with wet mount microscopy findings rather than PCR findings as the exposure definition, revealed that the adjusted OR for HIV infection in T.

When matched variables were adjusted for in the multivariable model, the effect of T. In this nested case-control study, we have demonstrated a strong association between infection with T. Our study included several unique factors designed to improve the precision of the estimate of the impact of T. First, to our knowledge, this is the first longitudinal study to measure this association in a general population group of women i.

Second, the use of highly sensitive nucleic acid amplification techniques for the diagnosis of C. For Finally, although matching may introduce selection bias, it may be useful in certain situations. The bias that may be introduced by matching is predominately toward the null hypothesis, as it equalizes groups before analysis [ 17 ]. However, in this study, the findings were highly robust even when matching variables were adjusted for in multivariable models. Although we acknowledge that matching is not an ideal component of study design, in this study it allowed us to determine the effect of T.

The study from which the samples and behavioral data were taken was designed to provide follow-up visits that were sufficiently frequent such that the lag time between testing should not have influenced the findings.

In a study of the natural history of T. However, the impact of T. This finding may be a reflection of the organism load necessary for trichomonads to be observed microscopically. Performing wet mount microscopy during clinic visits where clients can be treated for trichomoniasis vaginalis or bacterial vaginosis may be a valuable tool for reducing the risk of HIV infection, because wet mount microscopy is inexpensive and easy to perform.

One of the inherent difficulties with estimating the impact of any STI on HIV acquisition is the shared mechanism for transmission.
