An immunohistochemistry and histopathological study of ankaferd blood stopper in a rat model of cervical inflammation

SUMMARY OBJECTIVE: Ankaferd Blood Stopper (ABS) is a medicinal plant extract used topically as a hemostatic, anti-inflammatory, and anti-oxidant agent. Its cytoprotective effect mainly depends on its pleiotropic properties by modulating inflammatory mediators such as IL-1β, IL-6, and TNF-α. This study aims to test the possible therapeutic effect of ABS in the treatment of erosive and inflammatory conditions occurring in the uterine cervix. METHODS: Twenty-four female Wistar Albino rats were used in the present study. Trichloracetic acid was applied intravaginally to establish an experimental rat model of cervicitis. The rats were randomly divided into three groups: group I (injury), group II (injury+isotoinc saline), and group III (injury+ABS). After 3 estrous cycles of ABS and isotonic saline treatment, the amount of inflammation, vascular congestion and erosion were evaluated in the cervical tissues by using a modified semi-quantitative scale of 0-3. Immunohistochemical staining with monoclonal antibodies against IL-1β was also performed. RESULTS: Compared with group I and II, the ABS group showed the least inflammatory cell infiltration, vascular congestion and cervical erosion, compared with the ABS group prominent IL-1β staining observed in group I and group II. CONCLUSION: Our data suggest that ABS is a highly effective alternative to induce normal cervical epithelium and can be used safely in the treatment of cervical inflammation with or without cervical erosion.

RESUMO OBJETIVO: Ankaferd Blood Stopper (ABS) é um extrato de plantas medicinais utilizado topicamente como um agente hemostático, anti-inflamatório e antioxidante. O seu efeito citoproteico depende principalmente das suas propriedades pleiotrópicas por meio da modulação de mediadores inflamatórios tais como IL-1β, IL-6 e TNF-a. O objetivo deste estudo é testar o possível efeito terapêutico do ABS no tratamento de condições erosivas e inflamatórias que ocorrem no colo uterino. MÉTODOS: Vinte e quatro ratas Wistar Albino foram utilizadas no presente estudo. O ácido tricloroacético foi aplicado intravaginalmente para estabelecer um modelo experimental de cervicite em ratos. Os ratos foram divididos aleatoriamente em três grupos: grupo I (lesão), grupo II (lesão + fisiológico sérico) e grupo III (lesão + ABS). Após três ciclos estrais de ABS e tratamento fisiológico sérico, as quantidades de inflamação, congestionamento vascular e erosão foram avaliadas nos tecidos cervicais usando uma escala semiquantitativa modificada de 0-3. Coloração imuno-histoquímica com anticorpos monoclonais contra IL-1β também foi realizada. RESULTADOS: Em comparação com os grupos I e II, o grupo ABS mostrou menos infiltração de células inflamatórias, congestionamento vascular e erosão cervical. Além disso, em comparação com o grupo ABS, observou-se uma coloração proeminente de IL-1β no grupo I e no grupo II. CONCLUSÃO: Nossos dados sugerem que o ABS é uma alternativa altamente eficaz para induzir o epitélio cervical normal e pode ser utilizado com segurança no tratamento da inflamação cervical com ou sem erosão cervical.

Ausencia de lesión intraepitelial en piezas de conización / Related factors to absence of cervical intraepithelial neoplasia in the conization specimen

Resumen OBJETIVO: Investigar las posibles causas de los conos blancos, establecer estrategias para disminuir su incidencia y desarrollar protocolos de seguimiento. MATERIALES Y MÉTODOS: Estudio observacional, retrospectivo, de casos y controles. Se incluyeron las pacientes a quienes se efectuó una conización en el Hospital Universitario La Paz. Las variables analizadas más importantes fueron: anatomía patológica de la pieza y su relación con la biopsia y citologías previas, longitud del cono, presencia o no de artefacto y de cervicitis. Para el análisis estadístico se utilizaron: χ2, prueba exacta de Fisher, t de Student, U de Mann-Whitney, Kruskal-Wallis y Kolmogorov-Smirnov. RESULTADOS: Se integraron dos grupos: 371 conos positivos (85.9%) y 61 negativos (14.1%), con diferencias estadísticamente significativas en la citología, colposcopia y biopsia. Hubo mayor porcentaje de lesiones de menor grado en las pacientes con conización blanca. La longitud del cono fue menor en el grupo de análisis y en éste también se observó mayor porcentaje de cervicitis y artefactos. CONCLUSIONES: Las causas de lesión residual luego de una conización son variadas y difíciles de demostrar. Las pacientes con citología anómala e inflamación o atrofia deben recibir tratamiento para evitar falsos positivos y mejorar la técnica quirúrgica para impedir artefactos.

Abstract OBJECTIVES: to investigate the possible causes of the negative cones, to establish strategies to reduce their incidence and to develop monitoring protocols. MATERIALS AND METHODS: This is a retrospective observational cases and controls study of 432 conizations made in the Hospital Universitario La Paz (HULP) between 2013 and 2015. The most important analysed variables were the pathological anatomy of the piece and its relationship with the biopsy and previous cytology, the cone length, as well as the presence and artefact and cervicitis. The analysis it was used Chi - Square and Fisher´s test, T-Student, Mann Whitney U, Kruskal-Wallis and Kolmogorov- Smirnov. RESULTS: There are two groups: 371 positive (85,9%) and 61 negative cones (14,1%). We find statistically significant differences in the cytology, colposcopy and biopsy pre-conization, finding a major percentage of injuries of lesser degree in the patients with negative cone. The length of the cone was lower in the analysis group and in this we also observed a greater percentage of cervicitis and artefacts. CONCLUSIONS: The causes that make the remaining injury not appear after a diagnosed and/or therapeutic conization are a wide variety and difficult to prove. We should try to treat the patients with inflammation or atrophy to avoid false positives in the cytology and biopsy, improve the surgical technique to avoid artefacts and perform conservative management of low-risk injuries.

Association of Ureaplasma urealyticum biovar and genotype with mucopurulent cervicitis / 中华皮肤科杂志

Objective To study the association of U. urealyticum biovar and genotype with nongonococcal, nonchlamydial mucopurulent cervicitis. Methods The study population consisted of two groups: patient group (226 female patients with nongonococcal, nonchlamydial mucopurulent cervicitis) and control group (118 healthy women). The biovar and genotype of U. urealyticum were identified in specimens positive for U. urealyticum culture by using PCR-single-strand conformation polymorphism (PCR-SSCP) analysis. Results The most common genotype in both groups was mba 3/14 in biovar 1 with the detection rate being 30.98%(57/184) in patients with mucopurulent cervicitis and 43.42% (33/76) in the controls. A significant difference was observed in the prevalence of genotype 2B in biovar 2 between the patients and controls [16.30% (30/184) vs 6.58% (5/76), χ2 = 4.367, P= 0.037). The genotype 1, 3/14 and 6 in biovar 1 predominated in the controls with their total prevalence being 81.58%. Conclusion The genotype 2B in biovar 2 of U. urealyticum may be associated with nongonococcal, nonchlamydial mucopurulent cervicitis among female patients attending an STD clinic.

Rastreamento universal para cervicite clamidiana: uma revisão sistemática / Universal screening for chlamydial cervicitis: a systematic review

A revisão sistemática teve como objetivo avaliar a efetividade dos testes de ácido nucleico no rastreio da C. trachomatis. A maioria dos estudos foi localizada via internet, entretanto, alguns deles foram encontrados em revistas que abordavam o tema e mediante contato com especialistas. Os artigos foram selecionados após criteriosa avaliação crítica da força de evidência científica, obedecendo às regras da Associação Médica Brasileira e do Conselho Federal de Medicina, além dos critérios de Irwig, para análise qualitativa dos artigos. A revisão incluiu todos os estudos publicados a partir de 1990 que avaliavam testes de ácido nucleico em mulheres sexualmente ativas, assintomáticas e que tivessem sido submetidas à avaliação clinica e a testes moleculares. Os testes de ácido nucleico que utilizavam sondas de RNA e amplificação de DNA (PCR) foram comparados à cultura (padrão-ouro) com o intuito de determinar se seriam método de diagnóstico adequado para o rastreio da infecção. Após análise qualitativa, foram selecionados 12 estudos, mas não foi possível realizar avaliação quantitativa dos mesmos devido à heterogeneidade dos dados. A efetividade e os benefícios dos testes de ácido nucleico justificam estudos de custo-efetividade, com o intuito de avaliar o impacto do rastreio universal na redução das complicações advindas da infecção clamidiana

This systematic review aims at evaluating the effectiveness of the nucleic acid test for detection of C. trachomatis. Most of the studies were searched electronically and key journals were hand-searched. Further studies were identified in the internet and by contacting experts in the field. The articles were selected after careful critical evaluation of the strength of scientific evidence, according to the rules of the Brazilian Medical Association and the Federal Council of Medicine, besides the Irwig's criteria for qualitative analysis of article The review included all studies published from 1990 onward that evaluated nucleic acid tests in asymptomatic, young and sexually active women that have been subjected to clinical evaluation and molecular testing. The nucleic acid tests taken with the use of probes of RNA and amplification (PCR) were compared to culture (gold standard) in order to determine if a method of diagnosis would be appropriate for screening of infection. After the qualitative analysis, we selected 12 studies; it has not been possible to perform their quantitative evaluation due to the heterogeneity of data. The effectiveness and benefits of DNA testing justify the cost-effectiveness studies in order to assess the impact of universal screening in reducing the complications that arise from chlamydial infection

Study of local immunity of lower genital tract infections / 中华妇产科杂志

Objective To investigate the profile of local immunity of vagina and the immune defense mechanisms against lower genital tract infections. Methods Vaginal lavage was collected from healthy women and patients of vulvovaginal candidiasis, bacterial vaginosis, Trichomonol vaginitis, human papilloma virus infection(VVC), and chlamydia trachomatis infection. Each group included 60 cases. The level of interleukin (IL) 2,4,5, 13,8 and human defensin 5 (HD5) were detected by enzyme linked immunosorbent assay(ELISA). Results (1) Cytokine of helper T cell 1(Th1): the level of IL-2 between healthy women and VVC/ bacterial vaginosis (BV)/ trichomonol vaginitis (TV)/ chlamydia trachomatis (CT) patients had no significant difference. The IL-2 level(96±33 )×10-3 pg/L of human papilloma virus (HPV) infection patients was significantly higher than that of healthy women( P<0.05). (2)Cytokine of helper T cell 2 (Th2) : the level of IL-4 between healthy women and VVC/CT patients had no significant difference. The level of IL-5 between healthy women and BV patients had no significant difference. The IL-13 level(42±15)×10-3 pg/L of TV patients was significantly higher than that of healthy women (30±29)×10-3 pg/L (P<0.05). The IL-4 level (103±28)×10-3 pg/L of HPV infection patients was significantly higher than that of healthy women (36±22)×10-3 pg/L (P<0. 05 ). (3) IL-8 : the IL-8 level (5.8± 2.7) pg/L of TV infection patients was significantly higher than that of healthy women (2. 6±2.4) pg/L (P<0.05). The level of IL-8 between healthy women and BV patients had no significant difference. (4)HD5:the HD5 level of TV , BV, VVC, HPV and CT infection patients were significantly higher than that of healthy women (P<0.05). Conclusions (1) HD5 plays an important role in the defence of vaginal epithelial cell. (2) Th2 may be more important than Thl in lower genital tract infections.(3) IL-8 plays an important role in extrinsic source infections.

Evidence for benefits from treating cervical ectopy: literature review / Evidências de benefícios no tratamento de ectopia do colo do útero: revisão de literatura

CONTEXT AND PURPOSE: Uterine cervical ectopy (cervical erosion) is today considered to be a physiological condition, but there still seems to be a strong tendency towards treating it. The purpose of this study was to review the medical literature for evidence regarding benefits from treating cervical ectopy. METHODS: The following databases were reviewed: Medical Literature Analysis and Retrieval System Online (Medline), Excerpta Medica Database (Embase), Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs) and Cochrane Library databases. In addition, six medical textbooks were consulted. RESULTS: The review showed that: 1) there is probably an association between ectopy and higher risk of Chlamydia trachomatis, human papillomavirus and human immunodeficiency virus infection; 4) there is probably an association between ectopy and cervical intraepithelial neoplasia; 5) there is an association between ectopy and mucous discharge and nocturia; and 6) there is no evidence of an association between ectopy and cervical cancer, or of protection against cervical cancer associated with ectopy treatment. CONCLUSIONS: 1) No data were found in the medical literature to support routine treatment for ectopy; 2) Treatment could be recommended for symptom relief, but more symptoms are attributed to ectopy than could be demonstrated in a controlled study; 3) Further studies to test the hypothesis of protection against cervical cancer associated with treatment are necessary.

CONTEXTO E OBJETIVO: A ectopia do colo do útero é hoje considerada um fenômeno fisiológico, mas parece ainda haver uma forte tendência no sentido da intervenção (tratamento). Este estudo se propõe a realizar revisão da literatura buscando evidências de benefícios conseqüentes ao tratamento da ectopia. MÉTODOS: Pesquisa nas bases Medical Literature Analysis and Retrieval Sysem Online (Medline), Excerpta Medica Database (Embase), Literatura Latino-Americane e do Caribe em Ciências da Saúde (Lilacs), Biblioteca Cochrane e seis livros especializados. RESULTADOS: A revisão mostrou que: 1) existe provavelmente associação de ectopia com infecção cervical por Chlamydia trachomatis, pelo vírus HPV e maior risco de soroconversão para HIV; 2) existe provavelmente associação entre ectopia e neoplasia intra-epitelial cervical; 3) existe associação com mucorréia e nictúria; 4) não existem evidências sobre associação entre ectopia e câncer de colo do útero nem sobre proteção contra este câncer proporcionada pelo tratamento da ectopia. CONCLUSÕES: 1) Não foram encontrados na literatura dados que justifiquem o tratamento rotineiro da ectopia; 2) O tratamento pode ser utilizado para tratar sintomas associados à ectopia, porém mais sintomas são atribuídos à ectopia do que se pôde confirmar em um estudo controlado; 3) Seriam necessários novos estudos para testar a hipótese de proteção contra o câncer de colo proporcionada pelo tratamento.

Relationship between Mycoplasma genitalium and mueopurulent cervicitis / 中华皮肤科杂志

Objective To study the relationship between M. Genitalium and nongonococcal, non-chlamydial mucopurulent cervicitis. Methods A total of 226 patients with nongonococcal, nonchlamydial mu copurulent cervicitis and 118 healthy female volunteers were recruited in this study. Cervical samples were collected and M.genitalium was detected by PCR amplification of 16s rRNA and Pa genes. Information about socio-demographic characteristics, medical history, and sexual behaviors was gathered by questionnaire from both populations. Results The prevalence of M. Genitalium infection was 11.06% (25/226) in patients with mucpurulent cervicitis, 0,85% (1/118) in the healthy controls; the difference was significant between the two groups (x2 = 11.58, P < 0.001). Single variant analysis on the 226 patients showed that the preva-lence of M. Genitalium infection was 27.78%, 16.36%, 18.28% and 14.12% in patients with ectopic pregnancy history, cervical inflammation, pelvic organ tenderness, 10 or more polymorphonuclear leukocytes (PMNs)per oil immersion field in cervical discharge, respectively, significantly higher than that in patients without ectopic pregnancy history, cervical inflammation or pelvic organ tenderness, and those with less than 10 PMNs per oil immersion field in cervical discharge (9.62%, 6.03%, 6.02% and 1.79%, all P < 0.05). M.genitalium infection was also related to multiple sex partners and the presence of mucopurulent secretion in cervix (P < 0.001). Conclusion The prevalence of M.genitalium infection is higher in patients with non-gonococcal, nonchlamydial mucopurulent cervicitis attending STD clinic than that in normal population.
