Virological studies on gynaecological patients

Area of Science:

• Gynecology
• Virology
• Immunology

Background:

• Menstrual bleeding disorders affect numerous women, with underlying causes often multifactorial.
• The role of viral infections in gynecological conditions, including abnormal uterine bleeding, is an area of ongoing research.

Purpose of the Study:

• To investigate the presence of viral infections in endometrial tissues and blood samples from patients with menstrual bleeding disorders.
• To determine if specific viruses, such as adenovirus and herpesvirus, are associated with these conditions.

Main Methods:

• Viral isolation and identification from endometrial samples and blood (serum) of 138 patients.
• Immunofluorescence microscopy to detect viral antigens in endometrial cells.
• Serological testing (first and convalescent sera) for antibody titers against adenovirus and herpesvirus.

Main Results:

• Fourteen adenovirus type 2 strains were isolated from patient samples.
• Viral antigens, identified using adenovirus and herpesvirus antisera, were detected in endometrial cells of 23 out of 35 examined patients via immunofluorescence.
• Serological analysis revealed high antibody titers against herpesvirus type 2 in both acute and convalescent sera, and a significant rise in titers against latent adenovirus types in convalescent sera.

Conclusions:

• The findings suggest a potential association between adenovirus and herpesvirus infections and menstrual bleeding disorders.
• Viral antigens and specific antibody responses indicate a possible role for these viruses in the pathogenesis of abnormal uterine bleeding.
• No evidence of viral presence was found in samples from induced abortions, highlighting the specificity of findings in the patient group.
