Abstract Objectives: The aim of this study was to evaluate and compare concentration of selected human β-defensins (hBD-1, hBD-2) in cervico-vaginal lavage (CVL), obtained from women with candidiasis, chlamydiasis and other bacterial infections. Material and methods: β-defensins were detected quantitatively by RT-PCR (7000 Taqman, Applied Biosystems) in cervico-vaginal lavage collected from 120 (79 women in the study group and 41 controls) non-pregnant women, aged 18-40 (mean age 28.5}6.29). The study group patients were divided into three subgroups on the basis of clinical and microbiological diagnosis: women with candidiasis (n=13); with chlamydiasis (n=13), and with other bacterial infections (n=12). Results: The highest count of hBD-1 RNA copies was found in women with bacterial infections and candidiasis (335.84 and 320.10 respectively), and hBD-2 – with chlamydiasis. The difference between RNA copies of hBD-1/μg in candidiasis, chlamydiasis and bacterial pathogens was statistically significant; for hBD-2 only in case of chlamydiasis. Conclusions: Chlamydia trachomatis infection activates the production of hBD-2. Candida albicans, Chlamydia trachomatis, and bacterial pathogens induced variable increases of hBD-1 concentration.
