The analysis of cervicovaginal microbiota and immune mediators in patients with adenomyosis.

OBJECTIVE

Aim: To determine and characterise changes associated with microbial, inflammatory and immune factors in patients with adenomyosis.

PATIENTS AND

METHODS

Materials and

Methods

115 female patients were enrolled in the study, including 85 patients with adenomyosis and 30 healthy individuals. Vaginal cleanliness was assessed by collecting vaginal samples and plating on solid bacterial agar. Urogenital infections were determined by the PCR analysis of the cervicovaginal samples. The immunological characterisation was performed using enzyme immunoassay to analyse cervicovaginal lavage for β-defensin-2 and a defined set of cytokines. Antibody titers were quantified in patients' serum using nephelometry.

RESULTS

Results

Patients with adenomyosis displayed disrupted cervicovaginal microflora that was characterised by elevated levels of pro-inflammatory cytokines and antimicrobial peptide β-defensin-2. Serum analysis of patients with adenomyosis revealed higher concentration of IgG, IgM and IgA antibodies compared to healthy control groups.

CONCLUSION

Conclusions

Analysis of inflammatory and immunological parameters in patients with adenomyosis revealed distinct features of the pathophysiology of adenomyosis. Specifically, patients with adenomyosis had disrupted cervicovaginal microflora with higher prevalence of anaerobic species. Furthermore, patients with adenomyosis had elevated levels of pro-inflammatory cytokines and interleukins in cervicovaginal lavage, and higher levels of IgG, IgM and IgA antibody serum titres. The analysis presented in the paper represents an important step towards determining precise diagnostic parameters and effective therapies to treat adenomyosis.
