Trichomonas vaginalis infection among married women of Andaman and Nicobar islands

BACKGROUND

Trichomoniasis is a common sexually transmitted infection among both men and women, worldwide. The prevalence of trichomoniasis among married women in the remote Indian population is more important, yet they rarely sought treatment. This was the first-ever study conducted on the prevalence of Trichomonas vaginalis (TV) in the Andaman and Nicobar Islands.

METHODS

A cross-sectional study was undertaken among married women in the Andaman Islands, India from August 2020 to July 2022. Samples were collected from the suspected women attending community health centres after obtaining informed consent. PCR assay for TV was performed using specific primers and conditions. Further, sequencing was carried out and pair-wise genetic analysis was done using MEGA version 11 to find the TV strain.

RESULTS

Overall, 0.9% (nine out of 1000) TV cases were reported. The majority of infected population was below high school degrees (5/9) and was unemployed (7/9). Infected individuals never had a history of a sexually transmitted illness. Two of the ladies reported dyspareunia, and one of them had persistent pelvic pain. Of these, most of them had pelvic inflammatory disease (PID) and abnormal vaginal discharge. The pair-wise genetic distance analysis found the strain found on this island was TV G3.

CONCLUSIONS

From our knowledge, this surveillance study was conducted first time in the Andaman and Nicobar Island. The detection of the TV G3 strain may be essential for understanding the prevalence of TV infection and their associated risk factors. More research is needed to understand the TV-associated risk factors among suspected patients in hospital settings.

Epidemiology of Chlamydia trachomatis in the Middle East and north Africa: a systematic review, meta-analysis, and meta-regression

BACKGROUND

The epidemiology of Chlamydia trachomatis in the Middle East and north Africa is poorly understood. We aimed to provide a comprehensive epidemiological assessment of C trachomatis infection in the Middle East and north Africa.

METHODS

We did a systematic review of C trachomatis infection as well as a meta-analysis and meta-regression of C trachomatis prevalence. We searched PubMed and Embase, as well as regional and national databases up to March 13, 2019, using broad search terms with no language or year restrictions. Any document or report including biological measures for C trachomatis prevalence or incidence was eligible for inclusion. We extracted all measures of current (genital or rectal), recent, and ever infection with C trachomatis. We estimated pooled average prevalence in different populations using random-effects meta-analysis. Factors associated with prevalence and sources of between-study heterogeneity were determined using meta-regression.

FINDINGS

We identified a total of 1531 citations, of which 255 reports contributed to 552 C trachomatis prevalence measures from 20 countries. No incidence measures were identified. Pooled prevalence of current genital infection was 3·0% (95% CI 2·3-3·8) in general populations, 2·8% (1·0-5·2) in intermediate-risk populations, 13·2% (7·2-20·7) in female sex workers, 11·3% (9·0-13·7) in infertility clinic attendees, 12·4% (7·9-17·7) in women with miscarriage, 12·4% (9·4-15·7) in symptomatic women, and 17·4% (12·5-22·8) in symptomatic men. Pooled prevalence of current rectal infection was 7·7% (4·2-12·0) in men who have sex with men. Substantial between-study heterogeneity was found. Multivariable meta-regression explained 29·0% of variation. Population type was most strongly associated with prevalence. Additional associations were found with assay type, sample size, country, and sex, but not with sampling methodology or response rate (about 90% of studies used convenience sampling and >75% had unclear response rate). There was no evidence for temporal variation in prevalence between 1982 and 2018.

INTERPRETATION

C trachomatis prevalence in the Middle East and north Africa is similar to other regions, but higher than expected given its sexually conservative norms. High prevalence in infertility clinic attendees and in women with miscarriage suggests a potential role for C trachomatis in poor reproductive health outcomes in this region.

[Vulvovaginal candidiasis in pregnant women in the Mère et Enfant Hospital center in Nouakchott, Mauritania]

AIM

To determine the prevalence and the associated risk factors of vulvovaginal candidiasis in pregnant women in Mauritania.

PATIENTS AND METHOD

The study was carried out at the laboratory of the Mère et Enfant Center in Nouakchott, from November 1, 2016 to February 5, 2017. It concerned all pregnant women in the third trimester that came to the natal consultation at the gynecology service. These women must have given their informed consent in written form. After completing the survey to collect epidemiological and clinical data, a sample was collected to perform fresh direct examination and culture on Sabouraud-Chloramphenicol media.

RESULTS

Two hundred pregnant women were included in the study. Culture on Sabouraud-Chloramphenicol media was positive in 52 patients corresponding to a prevalence of 26%. The germ tube test was positive for 61.5% of isolated Candida. Clinical signs are dominated by leucorrhea (56%), pelvic pain (25%) and vulvar pruritus (11%). Among women with positive culture, 55.76% had received local antifungal treatment in the form of an ovula during pregnancy.

CONCLUSION

This study shows that vulvovaginal candidiasis is frequent in pregnant women attending gynecology at the Mère et Enfant Hospital Center in Nouakchott.

Aspergillus in liquid-based cervicovaginal cytology in a postmenopausal patient: A case report

Aspergillus is an opportunistic fungus present in humid environments, whose natural environment is in soil, hay and compost. It is a frequent contaminant in the clinical laboratory. Because of this, the fungus is often inhaled, affecting those with an underlying pulmonary disease or immune deficiency. Fungal genitourinary tract infections are relatively common. A rare Aspergillus spp cervical infection diagnosed via liquid-based cytology is presented in the current study. The 57-year-old woman attended her annual check-up without any relevant medical history. The result of a gynecological examination by Papanicolaou smear was normal and routine liquid-based cytology was performed. The specimen exhibited fungal organisms characterized by septate hyphae branching at acute angles, most consistent with the Aspergillus species. Subsequent cytology demonstrated the same results. Antifungal treatment was initiated and a second post-treatment smear only exhibited atrophy. The cytomorphological features of Aspergillus spp. are discussed in the current study and a brief review of the few reported cases of a primary cervical infection in the literature is provided. In addition, the liquid-based cytology was established as a tool to diagnose the rare Aspergillus infection.

Gynecologic infections seen in ThinPrep cytological test in Wuhan, China

This study aimed to analyze the prevalence of bacterial, Candida, Trichomonas, and human papillomavirus (HPV) infections in ThinPrep cytological test (TCT) performed on women of Wuhan, China. ThinPrep smears were screened by two independent experienced pathologists and reported from 2008 to 2010. A total of 46 866 ThinPrep smears were studied, and smears with inflammation were analyzed. Of the 44 162 enrolled patients, inflammation changes were observed in 21 935 (49.7%) and specific infections in 6884 (31.4%). The infections detected were as follows: bacteria, 5663 (82.3%); Candida, 825 (12.0%); Trichomonas, 273 (4.0%); and HPV, 148 (2.1%). Significant changes were found in the prevalence of bacteria and Candida among women who underwent TCT before and after 2010. χ(2) revealed an increasing proportion of specific infections found in smears after 2010 (P = 0.000). In conclusion, bacterial infection was the most detectable in the ThinPrep smears, followed by Candida and Trichomonas. The prevalence of infection identified by TCT was found to be similar in previous literature in China.
