Diagnosis of Trichomonas vaginalis infection: The sensitivities and specificities of microscopy, culture and PCR assay.

OBJECTIVES: The aim of this study was to compare wet mount-, Giemsa stain-, acridine orange fluorescent stain-, cultivation- and polymerase chain reaction (PCR)-based approaches to establish which method or combination of methods was most effective in the laboratory diagnosis of trichomoniasis. STUDY DESIGN: Out of 200 investigated patients with various gynecological complaints, Trichomonas vaginalis infection was detected in 27 (13.5%) by any of methods investigated. Among women with trichomonads, a typical clinical finding was presented in only nine. For analysis of sensitivity and specificity of the methods used, the receiver operating characteristic (ROC) curve concept with culture as a gold standard was applied. RESULTS: Infection was diagnosed by wet mount in 14 (7.0%) women, by Giemsa stain in 11 (5.5%) and by acridine orange stain in 16 (8.0%) women. In 21 (10.5%) women, it was diagnosed by culture in Diamond's medium, and in 22 (11.0%) by PCR. For the initial diagnosis of trichomoniasis, wet preparation is the test that is widely available in most STD clinics, but its sensitivity is poor (66.67%). Giemsa stain shows a low sensitivity of 52.38%. Acridine orange shows reasonable sensitivity and specificity of 71.43% and 99.44%, respectively. The sensitivity and specificity of PCR (80.95% and 97.21%) did not exceed that of culture. CONCLUSION: With regard to the fact that trichomoniasis can have an atypical or even asymptomatic course, in order to accurately diagnose this disease, microbiological investigation is necessary. Comparison of different methods showed that at least two techniques, such as culture and acridine orange staining, have the potential for better diagnosis of T. vaginalis infection. PCR detection of infection has been demonstrated to be highly specific and sensitive, but its availability and cost effectiveness are in question. PCR could provide an alternative for laboratory diagnosis of trichomoniasis by culture.

Chemotherapeutic approaches to protozoa: Giardia, Trichomonas and Entamoeba--current level of knowledge and outlook.

The situation regarding the treatment of human Giardia and Trichomonas infections and the intestinal and tissue stages of Entamoeba histolytica with metronidazole and other 5-nitroimidazoles is currently satisfactory (Table 1; Mehlhorn 2000). Following correct and rapid diagnosis, the parasites are eliminated reliably and completely. The situation in cases of infection with Acanthamoeba (often involving the eyes) or with Naegleria (often involving the brain) is serious, however. In both cases, there is no drug of choice available. Treatment consists of relieving the symptoms and/or preventing local degeneration.

Contribution of HIV-1 infection to acquisition of sexually transmitted disease: a 10-year prospective study.

BACKGROUND: Sexually transmitted diseases (STDs) enhance human immunodeficiency virus (HIV)-1 susceptibility, but few studies have examined the reciprocal effect of HIV-1 on STD acquisition. METHODS: Data from a prospective cohort study conducted among female sex workers in Mombasa, Kenya between 1993 and 2003 were used to determine the effect of HIV-1 infection on STD susceptibility. The cohort included 1215 HIV-1-seronegative women who underwent monthly HIV-1 and STD screening, of whom 238 experienced seroconversion to HIV-1 during follow-up. Andersen-Gill proportional-hazards models were used to compare the incidence rates for genital-tract infections (syphilis, genital ulcer disease [GUD], Neisseria gonorrhoeae infection, Chlamydia trachomatis infection, Trichomonas vaginalis infection, vulvovaginal candidiasis, and bacterial vaginosis) in HIV-1-seropositive versus HIV-1-seronegative women, after controlling for sexual behavior and other potential confounding factors. RESULTS: HIV-1 infection was associated with a significantly higher incidence of GUD (hazard ratio [HR], 2.8; 95% confidence interval [CI], 2.0-3.9), gonorrhea (HR, 1.6; 95% CI, 1.1-2.2), and vulvovaginal candidiasis (HR, 1.5; 95% CI, 1.3-1.8). The risks of GUD and vulvovaginal candidiasis increased with progressive levels of immunosuppression. CONCLUSIONS: The increased incidence of genital-tract infections among HIV-1-seropositive women could promote the spread of both HIV-1 and other STDs, particularly in areas where these conditions are highly prevalent.

An evaluation of an InPouch TV culture method for diagnosing Trichomonas vaginalis infection.

A new culture method for Trichomonas vaginalis, the InPouch TV test, was evaluated for its sensitivity and specificity in supporting growth of trichomonads. Five clinical isolates remained viable for periods from 41 to 131 days. A strain from the ATTC 30001 remained viable for 91 days. As few as four trichomonads/ml of culture medium could be viewed microscopically within 24 h. Doubling time for growth of trichomonad varied between 5 to 8 h. In a clinical study of 102 wet-mount negative specimens, 15 culture positive patients were observed with the InPouch TV test compared with 12 of the same patients with Hollander's fluid medium.

Trichomonas vaginalis infection in pre-pubertal girls.

This short paper discusses the implications of Trichomonas vaginalis infection of the genital tract in children with respect to suspected child abuse. Two case reports are described to illustrate the problems that can arise in the investigation of such cases T. vaginalis is usually transmitted sexually but the potential for non-sexual transmission does exist.

Obstetric and newborn outcomes in a cohort of HIV-infected pregnant women: a report of the women and infants transmission study.

OBJECTIVE: To determine obstetric and neonatal outcomes in a cohort of HIV-infected pregnant women and to assess whether HIV-related immunosuppression increases the risk of adverse outcomes of pregnancy. METHODS: Between 1989 and 1994, interview, physical examination, laboratory, and medical record data were prospectively collected from HIV-infected pregnant women and on their newborns. Factors associated with adverse pregnancy outcome and HIV disease status were correlated with pregnancy outcome using logistic regression analysis. RESULTS: 634 women delivered after 24 weeks of gestation. Preterm birth, low birth weight, and small-for-gestational-age neonates occurred in 20.5%, 18.9%, and 24.0% of pregnancies, respectively. Factors associated with low birth weight were CD4 percentage <14%, history of adverse pregnancy outcome, pediatric HIV infection, bleeding during pregnancy, and Trichomonas infection. Preterm birth was associated with CD4 percentage <14%, a history of adverse pregnancy outcome, and bleeding during pregnancy. Being small for gestational age was associated with maternal hard drug use during pregnancy, Trichomonas infection, history of adverse pregnancy outcome, and hypertension. CONCLUSIONS: Adverse pregnancy outcomes are common for HIV-infected women and are associated with low maternal CD4 percentage and pediatric HIV infection. Preterm birth, low birth weight, and small-for-gestational-age ranking, however, are also associated with previously recognized sociodemographic and obstetric factors that are not unique to HIV infection.

Serodiagnosis of Trichomonas vaginalis infection by the indirect fluorescent antibody test.

The indirect fluorescent antibody test was used to detect antibodies to Trichomonas vaginalis in 200 antenatal patients. A total of 104 (52%) gave a positive reaction with antigen prepared from cultures of trichomonas isolated from seven of the patients. Antitrichomonal antibody was detected at a 1/4 dilution in 90% of patients with proven trichomoniasis, while the highest dilution at which antibody was detected was 1/32. IgG rather than IgM appeared to be the antibody class involved. Of those patients with no demonstrable trichomonal infection, 17% gave positive reactions at 1/4 dilution, while 64% had no demonstrable antibody. One of 30 children under 11 years of age gave a positive reaction.

Urinary tract infection with Trichomonas vaginalis in a premature newborn infant and the development of chronic lung disease.

We report a case of a low-birth-weight infant with an infection of the urinary tract with Trichomonas vaginalis, who later developed cystic chronic lung disease suggestive of Wilson-Mikity syndrome. Although she had mild respiratory distress syndrome at birth, the extent of the chronic lung disease was out of proportion to the initial illness. We speculate that maternal infection with this organism may have resulted in an inflammatory response that led to its development.

Comparative prevalence of infection with Trichomonas vaginalis among men attending a sexually transmitted diseases clinic.

OBJECTIVE: Although established in women as a common cause of vaginal discharge, the prevalence of Trichomonas vaginalis (TV) in men compared with other classic urethral pathogens has not been well characterized. To assess this issue, the authors compared the prevalence of Neisseria gonorrhoeae (GC), Chlamydia trachomatis (CT), and TV in consecutive men attending a sexually transmitted diseases (STD) clinic. METHODS: From June 1, 1998 to July 27, 1998, 454 consecutive men presenting to the Denver Metro Health Clinic with a new problem were tested for GC by urethral swab culture, for CT by polymerase chain reaction of urine, and for TV by urine sediment culture. RESULTS: GC, CT, and TV were detected in 23 (5.1%), 34 (7.5%), and 13 (2.8%) of men, respectively. There were significant differences by age for both CT (11.3% in men younger than 30 years versus 3.3% in men 30 years and older, P < 0.05) and TV (0.8% in men younger than 30 years versus 5.1% in men 30 years and older, P < 0.05). In 50 men 30 years or older with symptoms of urethral discharge, TV prevalence (12.0%) rivalled that of GC (12.0%) and CT (14.0%). In 45 men 30 years and older with nongonococcal urethritis, the prevalence of TV and CT were each 13.3%. Multivariate logistical regression analysis showed the presence of discharge and nongonococcal urethritis in men 30 years and older to be an independent predictor of TV. CONCLUSIONS: TV is common in men attending sexually transmitted disease clinics, especially in those 30 years or older, in whom it may account for as much urethritis as GC or CT. These findings suggest that in older men with nongonococcal urethritis, diagnostic evaluation, empiric treatment, and partner management should include the possibility of TV infection.

Ornidazole: a new antiprotozoal compound for treatment of Trichomonas vaginalis infection.

A new anti-protozoal compound, ornidazole, a derivative of nitroimidazole, was given in a single 2 g dose to 20 women with Trichomonas vaginalis infection. All the women were cured, but they suffered some side-effects. Plasma levels of ornidazole reached a peak five to eight times higher than minimum inhibitory concentrations and exceeded this level for at least 36 hours. It is therefore possible that a smaller dose might have had an adequate trichomonicidal effect and fewer side-effects. Further studies are in progress.
