The purpose of our study was to determine the prevalence of urogenital mixed infections and the sensitivity of mycoplasmas and ureaplasmas to antibiotics in reproductive aged women with pelvic inflammatory disease. 4720 samples of biomaterial were obtained by urethral and cervical canal scrapings in 2360 women of reproductive age with pelvic inflammatory disease (2 samples from each woman). In 2360 samples, Chlamydia trachomatis, Trichomonas vaginalis and Gardnerella vaginalis were determined by multiplex PCR. 2360 samples were examined using the culture method.The cultivation, identification and susceptibility testing of urogenital mycoplasmas and ureaplasmas to 9 antibiotics were conducted with the use of commercial kits. In the study of 2360 samples of biomaterial by PCR, bacterial vaginosis (37.4%) was most often determined in women with PID.Chlamydiatrachomatiswas found in 8.3%, Trichomonasvaginalis- in 1.2% of women with PID. The cultivation and identification of urogenital mycoplasmas and ureaplasmas using biochemical markers revealed: Ureaplasma spp. in 543 women (23.0%) and Mycoplasma hominis in 179 women (0.7% of the total number of women examined). Number of women with mixed infection (positive results for Chlamydia trachomatis, Gardnerella vaginalis, Ureaplasma spp. andMycoplasma hominis) was 112. (4.7% of the total number of women with PID). The study of antibiotic sensitivity showed that most strains of Ureaplasma spp. and Mycoplasma hominis are highly susceptible to tetracycline antibiotics, especially doxycycline.

ultrasound is considered to be the primary tool for preoperative assessment of ovarian masses; however, the discrimination of borderline ovarian tumours (BOTs) is challenging, and depends highly on the experience of the sonographer. The Assessment of Different NEoplasias in the adneXa (ADNEX) model is considered to be a valuable diagnostic tool for preoperative assessment of ovarian masses; however, its performance for BOTs has not been widely studied, due to the low prevalence of these tumours. The aim of this study was to evaluate the performance of ADNEX model for preoperative diagnosis of BOTs. retrospective analysis of preoperative ultrasound datasets of patients diagnosed with BOTs on the final histology after performed surgery was done at a tertiary oncogynaecology centre during the period of 2012-2018. 85 patients were included in the study. The performance of ADNEX model based on absolute risk (AR) improved with the selection of a more inclusive cut-off value, varying from 47 (60.3%) correctly classified cases of BOTs, with the selected cut-off of 20%, up to 67 (85.9%) correctly classified cases of BOTs with the cut-off value of 3%. When relative risk (RR) was used to classify the tumours, 59 (75.6%) cases were identified correctly. Forty (70.2%) cases of serous and 16 (72.7%) cases of mucinous BOTs were identified when AR with a 10% cut-off value was applied, compared to 44 (77.2%) and 15 (68.2%) cases of serous and mucinous BOTs, correctly classified by RR. The addition of Ca125 improved the performance of ADNEX model for all BOTs in general, and for different subtypes of BOTs. However, the differences were insignificant. The International Ovarian Tumour Analysis (IOTA) ADNEX model performs well in discriminating BOTs from other ovarian tumours irrespective of the subtype. The calculation based on RR or AR with the cut-off value of at least 10% should be used when evaluating for BOTs.

Circulating inflammatory markers in cervical cancer patients and healthy controls.

J Immunotoxicol 2020 12;17(1):105-109

There is increasing evidence that host inflammatory responses play an important role in the development and progression of cancers. There are some data that cancer is associated not only with inflammation at the site of the lesion, but also with dysregulations of the host overall systemic immune response. In the case of cervical cancer, inflammation is an important factor associated with the development, progression, and potential metastasis of the disease. What is unclear still in the potential for modifications of host responses to human papillomaviruses (HPV) - a known causative agent of CC, that could be induced by cigarette smoking. In particular, it remains to be determined how the inflammation induced by HPV infection could impact on CC incidence/severity. In this prospective study, serum levels of 10 cytokines were evaluated using Multiplex and ELISA assays. The samples were the sera of 43 CC patients and 60 healthy (NILM) controls. All outcomes were evaluated in relation to host HPV and to their smoking status. The results in indicated that serum sTREM-1, TNFα, IFNβ, IL-1β, and IL-6 levels were significantly increased in CC (HPV+) patients compared to healthy NILM controls. A similar trend was observed for IL-10 and IL-2 levels. Within the two groups, differences in cytokine levels between smokers and never smokers were not remarkable. The findings here support the hypothesized role of systemic inflammation in the pathophysiology of CC.

Lipocalin 2 (LCN2) has an oncogenic role in promoting tumorigenesis through enhancing tumor cell proliferation and the metastatic potential. The aim of our study was to determine whether serum LCN2 could serve as a diagnostic marker of cervical cancer (CC) and to evaluate the correlation between its serum concentration, the clinical stage of the cancer and Human Papilloma Virus HPV infections in women. A total of 33 women with histologically proven cervical cancer (CC), 9 women with high- grade cervical intraepithelial neoplasia (HSIL) and 48 healthy women (NILM) were involved in the study. A concentration of LCN2 was assayed with the Magnetic LuminexR Assay multiplex kit. An HPV genotyping kit was used for the detection and differentiation of 15 high-risk (HR) HPV types in the liquid-based cytology medium (LBCM) and the tissue biopsy. The majority (84.8%) of the women were infected by HPV16 in the CC group, and there was no woman with HPV16 in the control group ( < 0.01). Several types of HR HPV were found more often in the LBCM compared to in the tissue biopsy ( = 0.044). HPV16 was more frequently detected in the tissue biopsy than the LBCM ( < 0.05). The LCN2 level was higher in HPV-positive than in HPV-negative women ( = 0.029). The LCN2 concentration was significantly higher in women with stage IV than those with stage I CC ( = 0.021). Conclusions: Many HR HPV types, together with HPV16/18, can colonize the vagina and cervix, but often HPV16 alone penetrates into the tissue and causes CC. The serum LCN2 concentration was found to be associated not only with HR HPV infection, irrespective of the degree of cervical intraepithelial changes, but also with advanced clinical CC stage. LCN2 could be used to identify patients with advanced disease, who require a more aggressive treatment.

Anti-inflammatory and anti-oxidative effects of herbal preparation EM 1201 in adjuvant arthritic rats.

Medicina (Kaunas) 2015 17;51(6):368-77. Epub 2015 Nov 17.

State Research Institute Center for Innovative Medicine, Vilnius, Lithuania.

Background And Objective: The purpose of the present study was to examine the anti-arthritic and antioxidant effects of herbal and active organic ingredient complex (EM 1201) in rats with experimental adjuvant arthritis (AA).

Materials And Methods: AA was induced in 30 male Wistar rats by intradermal injection of complete Freund's adjuvant into the left hind paw. The course of disease in 30 rats in response to the treatment with EM 1201 and diclofenac, the parameters including body weight, joint swelling, blood indices pro-/antioxidant status of blood serum, and histology of joints and the liver, were investigated.

Results: Preparation EM 1201 showed anti-inflammatory effect analogous to diclofenac, improved blood indices, significantly decreased joint swelling and histological changes in them. Joint swelling was suppressed by 29%-42.8% and 9.3%-34.4% in response to administration of EM 1201 and diclofenac during the entire experiment. Both preparations significantly suppressed pannus formation, general inflammatory reaction and edema in soft periarticular tissues and synovium, diminished MDA level and elevated AOA in the blood serum. Significantly lower absolute and relative weight of the liver and lower dystrophic processes in it, and general inflammatory infiltration of hepatic stroma proved the positive effect of treatment with EM 1201.

Conclusions: The present study suggests that EM 1201 has protective activity against arthritis and demonstrated its potential beneficiary effect analogical to diclofenac. Anti-inflammatory and anti-oxidative effect of EM 1201 in rats with AA support the need of further investigations by using it as supplementary agent alone or together with other anti-arthritic drugs in the treatment of rheumatoid arthritis.
