Clinical Characteristics of Vaginal Trichomoniasis Infection and Metronidazole Resistance in Vaginitis Patients

Objective

This study aims to investigate the clinical characteristics of vaginal trichomoniasis infection among vaginitis patients and assess their resistance to metronidazole.

Methods

We conducted a retrospective study involving 687 vaginitis patients who visited our hospital from April 2022 to June 2024. Clinical data were collected through questionnaires that included information on age, occupation, season of infection, marital status, contraceptive methods, and frequency of vulvar hygiene. Vaginal secretions were examined for trichomoniasis, and the characteristics of the infection were analyzed. Multivariate logistic regression was employed to identify factors influencing vaginal trichomoniasis infection. Infected vaginal trichomonas samples were cultured in vitro, and metronidazole gradient concentration plates were prepared to determine the minimum lethal concentration (MLC) of metronidazole against vaginal trichomonas, allowing for an assessment of resistance.

Results

Out of 687 vaginitis patients, 65 were diagnosed with vaginal trichomoniasis, resulting in an infection rate of 9.46%. Significant differences in infection rates were observed based on age, occupation, season of infection, marital status, contraceptive methods, and frequency of vulvar hygiene (P < 0.05).

Conclusion

The infection rate of vaginal trichomoniasis is notably higher in younger vaginitis patients compared to middle-aged and elderly individuals, with a peak occurrence in spring. Higher rates were also noted among farmers, married individuals, those using oral contraceptives or no contraception, and those with infrequent vulvar cleaning. Additionally, resistance to metronidazole was identified in some cases. Clinical efforts should prioritize prevention and treatment strategies for high-risk populations.

Marine natural products

Covering: January to the end of December 2022This review covers the literature published in 2022 for marine natural products (MNPs), with 645 citations (633 for the period January to December 2022) referring to compounds isolated from marine microorganisms and phytoplankton, green, brown and red algae, sponges, cnidarians, bryozoans, molluscs, tunicates, echinoderms, the submerged parts of mangroves and other intertidal plants. The emphasis is on new compounds (1417 in 384 papers for 2022), together with the relevant biological activities, source organisms and country of origin. Pertinent reviews, biosynthetic studies, first syntheses, and syntheses that led to the revision of structures or stereochemistries, have been included. An analysis of NP structure class diversity in relation to biota source and biome is discussed.
