Prevalence of Trichomonas vaginalis Using Parasitological Methods in Tehran
2009
Background: Trichomonas vaginalis is a parasitic protozoan with a predilection for human urogenital tract and causative agent for vaginitis, cervicitis and urethritis in females. T. vaginalis is known as a cofactor in transmission of human immunodeficiency virus and may lead to adverse outcomes in pregnant women. The goal of this study was to determine the prevalence of T. vaginalis infection in females attending Mirzakuchak Khan Hospital, Tehran, Iran. Methods: During May 2008 to March 2009, 500 vaginal discharges samples were obtained from women attending sexual transmitted disease (STD) clinic of Mirzakuchak Khan Hospital in Tehran, Iran. The samples were examined by Dorsse culture medium and wet-mount methods. The prevalence of T. vaginalis was determined using culture based method and wet-mount examinations. Results: Sixteen positive (3.2%) and 484 negative (96.8%) samples for T. vaginalis were detected by culture based methods. The wet mount examination revealed 13 positive (2.6%) and 487 negative (97.4%) samples. In the above population, prevalence of trichomoniasis was estimated as 3.2% based on culturing method. Conclusion: Due to adverse outcomes of vaginal trichomoniasis and its correlation with HIV transmission, there is a great need for public education regarding implementation of personal hygienic measures and prevention of inappropriate sexual contacts.
Prevalence of Trichomonas vaginalis in Pregnant Women in Zanjan, Northwest of Iran
Jundishapur Journal of Microbiology, 2013
Background: In the last two decades the incidence of sexually transmitted infections (STIs) are dramatically increased and remain a major public health problem in developing countries. Trichomoniasis is the most common non-viral sexually transmitted infection caused by Trichomonas vaginalis which is a flagellated protozoon associated with vaginitis, cervicitis and urethritis. Researchers believed that pregnancy is one of the influencing factors of the genital trichomoniasis in women. Objectives: The aim of this study was to determine the prevalence of trichomoniasis in pregnant women in Zanjan, Iran. Materials and Methods: In this cross-sectional study, 1000 pregnant women were examined for diagnosis of trichomoniasis based on direct microscopic examination and culture method. They referred to the treatment and health centers of Zanjan, Northwest Iran, Demographic and personal information of the subjects were collected and evaluated with questionnaires. Results: Thirty-three out of one thousand examined individuals (3.3%) presented vaginal infection with T. vaginalis. Infection in women with lower gestational age, higher mothers' age, higher parity and living in city were significantly associated with increased risk of vaginal trichomoniasis (P < 0.05). Other variables were not significantly associated with parasite infection. Conclusions: The present study found that the infection with T. vaginalis is a health problem in pregnant women correlated with some epidemiological variables and can be considered with microbiological screening tests during pregnancy.

Background Trichomonas vaginalis (T. vaginalis) infection has been long considered among the sexually transmitted diseases that possesses a clear effect on women's health especially in the childbearing period. Methods A 234 females of age range 18-45 years old attending the Gynecology and Obstetrics Outpatient Clinic of Kasr El Aini Hospitals were enrolled in a cross-sectional study. The taken vaginal swabs were subjected to wet mount microscopy, Giemsa stain, modified Diamond's culture, and nested polymerase chain reaction (nPCR) amplification. Multiattribute and analytical hierarchy processes were conducted to detect laboratory utility. Univariate and multivariate analyses were done to detect the multiple risk factors that may be associated with Trichomonas infection. Results Based on nPCR, the prevalence of trichomoniasis was 26.9%. Wet mount, Giemsa stain, and culture showed 100% specificity but of low sensitivity (28.57%, 28.57%, and 57.14%, respectively). On the multiv...

BACKGROUND Trichomonas vaginalis (TV) is a parasitic protozoan that infects the genitourinary tract and produces the most common curable sexually transmitted disease (STD) in sexually active women. The aim was to study the prevalence of Trichomonas vaginalis infection in patients. MATERIALS AND METHODS This was a 6-month prospective study of all the Pap smear specimens received in the department of pathology. The smears were stained with Pap stain and H & E stain. After microscopy, if the trophozoite forms of T. vaginalis are seen the diagnosis is confirmed. The clinical details were taken from the case reports and requisition slips. RESULTS During this study, total 1650 Pap smears were received in the department of pathology out of which 149 patients were positive for the trophozoites making the prevalence rate in this study as 9.03% The 30-to 39-year-old age group had a significantly higher prevalence of infection (36.23 %; P < 0.05) than the 20-to 29-year-old (27.51 %) and 40-to 49-year-old age groups (20.13 %; P > 0.05). The lowest rates of infection were observed in those <20 years of age (6.71 %) and >50 years of age (9.39 %; P > 0.05). CONCLUSION The prevalence of TV was more in sexually active age group and its diagnosis is important as it can cause adverse effects in Antenatal care (ANC) period.

Background: There is little information about the prevalence and risk markers of Trichomonas Vaginalis (TV) in Islamic Republic of Iran. This study aimed to determine the prevalence of TV and to examine the factors associated with this infection. Methods: A sample of 550 sexually active women aged less than 45 years living in Babol were enrolled using systematic sampling technique. They were interviewed using a questionnaire, and all the subjects underwent pelvic examination and a discharge ectocervix sample was collected for the diagnosis of TV using wet smear. Results: The prevalence of TV was 4%, there being a significant association between TV and the sociodemographic variables such as the husband's education, and woman's age (20-30 years). The behavioral markers significantly associated with the infection were, not using condom, having ever heard of lack of information about STD/HIV (Sexual Transmitted Disease), and protected last sexual contact in that month and cigarette smoking by husbands. The signs significantly associated with the infection were vaginal discharge, mucopurulent cervicitis, and redness of vulvovaginal. Syndromic diagnosis revealed a moderate sensitivity of 55% and poor positive predictive value for infection. Conclusion: The prevalence of positive TV is low in the studied women. Therefore, a net diagnosis using laboratory tests is necessary before the initiation of treatment.

The present study aimed to determine the prevalence and associated risk factors of vaginal trichomoniasis in women referred to gynecologic clinic in Benha University Hospital, Egypt. Two hundred female patients enrolled in the study. Vaginal samples were obtained from them and examined for T. vaginalis by wet mount, Giemsa stain, Acridine orange (AO) stain and culture on modified Diamond's medium. For analysis of accuracy of the methods used, the receiver operating characteristic (ROC) curve concept with culture as a gold standard was applied. Out of 200 patients, T. vaginalis was found in 22 (11%) patients by any of the diagnostic methods used. The accuracy of AO staining comes next to Diamond's culture (AUC 0.909, sensitivity 81.8%, specificity 100%, CI 0.81-1.0) followed by Giemsa staining (AUC 0.835, sensitivity 68.2%, specificity 98.9%, CI 0.72-0.95). The wet mount was the least accurate method (AUC 0.795, sensitivity 59.1%, specificity 100%, CI 0.67-0.92). There was no...

There are insufficient data on the prevalence of Trichomonas vaginalis infection in pregnant women in South Africa. The present study aims to determine the prevalence of T. vaginalis (TV) in pregnant women and identify the risk factors associated with this infection in pregnancy. This was a cross-sectional study which included 362 pregnant women attending the antenatal clinic at the King Edward VIII Hospital in Durban, South Africa. A self-collected vaginal swab was provided by the enrolled women for laboratory diagnosis by real-time polymerase chain reaction. The protozoan load was determined as the logarithm of gene copies per milliliter. The prevalence of TV infection was 12.9% and 59.6% of the women who tested positive were asymptomatic (p ¼ 0.011). Women who presented with abnormal vaginal discharge had a 4.6 times likelihood of testing positive for TV infection (odds ratio 4.62; 95% confidence interval 1.83 to 11.70; p ¼ 0.001). TV infection was high amongst pregnant women. Therefore, routine testing for this sexually transmitted infection is encouraged for proper management.
