Causative Role of Sexually Transmitted Infections in the Development of Chronic Cystitis Complicated with Leukoplakia of the Bladder
The objective of this study was the investigation of the influence of chlamydial, mycoplasmal and trichomonas infection on the development of urinary bladder leukoplakia. The article presents the results of the examination of women with chronic cystitis complicated with leukoplakia of the bladder, and associated with concomitant sexually transmitted infections, including the results of culture analysis of the cervical canal content and urinary bladder biopsy samples, as well as molecular-biological analyses confirming the presence of sexually transmitted infections, pathomorphological characteristics of tissue samples from leukoplakia foci typical for different types of infectious agents. In this study, 60 women with chronic cystitis, complicated with leukoplakia of the bladder and associated with concomitant sexually transmitted infections were examined. Using PCR diagnostics, Mycoplasma hominis and Chlamydia albicans were found to be the most frequently occurring agents, followed by Ureaplasma urealyticum, Chlamydia trachomatis and Trichomonas vaginalis. The results of culture analyses demonstrated that M. hominis and U. urealyticum were prevalent in patients with chronic urinary tract inflammatory processes, followed by Tr. vaginalis. Candida fungi show practically the same frequency of occurrence. The pathomorphological examination of the foci of leukoplakia in the urinary bladder (in 30 subjects) demonstrated metaplasia of the transitional epithelium to the stratified pavement squamous epithelium with inflammatory cellular infiltration of the lamina propria in all types of infections. The intensity of the urothelial transformation and stromal inflammatory processes were determined by the type of predominant infection. Pathomorphological characteristics of the foci of leukoplakia correlate with the etiology of chronic inflammation and are relevant for etiological diagnosis and treatment
Causative Role of Ureaplasma Urealyticum and other Sexually Transmitted Infections in the Urethral Meatus Polyp Development in Women
The objective of this study was the investigation of the influence of ureaplasmal infection on the development of urethral meatus polyps in women. The article presents the results of the examination of women with chronic cystitis and urethritis over a 0.5- to 5-year duration, complicated by the presence of urethral meatus polyps and associated with concomitant Ureaplasma urealyticum and other sexually transmitted infections (STI). This was based on the culture analysis of the cervical and urethral content, and PCR-diagnostics of STI, as well as a complex pathomorphologic study of the resected polyps, including electron microscopy. In this study, 98 women between 45 and 60 years (52.5±4.9 years) were examined, who had undergone radiowave resection of the polyps: 52 women were infected by STI, including Ureaplasma urealyticum, Mycoplasma genitalium, Mycoplasma hominis, Chlamydia trachomatis and Trichomonas vaginalis, while the remaining 46 women had been diagnosed as not having STI. According to the culture results in the women with STI, U. urealyticum was identified as a monoinfection in 69% of cases, while in the remaining 31% of cases it was evident in the form of mixed infections, mainly in association with Mycoplasma hominis (17.5%) and Trichomonas vaginalis (13.5%). Pathomorphological examination of the urethral meatus polyps of the women with U. urealyticum and other STI demonstrated the proliferative character of the remodeling of the surface epithelium with hyperplasia, acanthosis, and keratinization of the stratified squamous epithelium and synchronous changes in the underlying connective tissue - impaired microcirculation and the diffuse inflammatory cell infiltrates with transepithelial leukopedesis. Using electron microscopy in the fibroblasts and plasma cells of the resected polyps the markers of U. urealyticum were detected in patients with negative results of the bacteriological diagnostic methods
