RESUMEN

The pathogenesis of Ebola virus disease (EVD) is still incomplete, in spite of the availability of a nonhuman primate modelfor more than 4 decades. To further investigate EVD pathogenesis, a natural history study was conducted using 27 Chinese-origin rhesus macaques. Of these, 24 macaques were exposed intramuscularly to Kikwit Ebola virus and euthanized at predetermined time points or when end-stage clinical disease criteria were met, and 3 sham-exposed macaques were euthanized on study day 0. This study showed for the first time that Ebola virus causes uterine cervicitis, vaginitis, posthitis, and medullary adrenalitis. Not only was Ebola virus detected in the interstitial stromal cells of the genital tract, but it was also present in the epididymal and seminal vesicular tubular epithelial cells, ectocervical and vaginal squamous epithelial cells, and seminal fluid. Furthermore, as early as day 3 after exposure, Ebola virus replicative intermediate RNA was detected in Kupffer cells and hepatocytes. These findings in the nonhuman model provide additional insight into potential sexual transmission, possible disruption of sympathetic hormone production, and early virus replication sites in human EVD patients.

RESUMEN

Objective: To explore the relationship between the expression of the T-cell activation suppressor-immunoglobulin variable region (VISTA) and the development of cervical squamous cell carcinoma (CSCC), and the impact on the prognosis of CSCC patients. Methods: Cervical tissue samples from 116 CSCC, including 23 cervical intraepithelial neoplasia (CIN) grade I, 23 CIN grade Ⅱ-Ⅲ, and 23 chronic cervicitis patients, were collected from the First Hospital of Soochow University between March 2014 and April 2019. The expression of VISTA in each group was detected by immunohistochemistry (IHC). Survival data of CSCC patients were obtained by follow-up. The survival analysis was performed by Kaplan-Meier method, and survival differences between groups were compared by Log rank test. Prognostic impact factors were analyzed using a multifactorial Cox proportional hazards model. Results: The positive rate of VISTA expression in CSCC group was 32.8% (38/116), and which of grade Ⅱ-Ⅲ was 17.4% (4/23). VISTA expression results showed no positive expression patients in the cervical intraepithelial neoplasia grade I and chronic cervicitis groups. The differences between the CSCC group and other groups were statistically significant (P<0.01). In 116 CSCC patients, VISTA expression was associated with International Federation of Gynecology and Obstetrics (FIGO) stage and lymph node metastasis (P<0.01). The mean survival time of patients in the VISTA positive expression group was 30.7 months, and the 3-year survival rate was 44.7% (17/38). However, the mean survival time of the patients in the VISTA negative expression group was 49.1 months, and the 3-year survival rate was 87.2% (68/78). The Cox regression model found that VISTA expression positivity (P=0.001) and FIGO stage (P=0.047) were prognostic factors for CSCC, and patients with VISTA-positive CSCC had a 4.130-fold risk of death higher than those with VISTA-negative expression. Conclusions: The VISTA protein is highly expressed in CSCC tissues, and its expression level is closely related to the occurrence and development of CSCC. The expression of VISTA can be used as an independent predictor of CSCC prognosis and can provide a strong basis for the treatment of CSCC with immune checkpoint inhibitors.

RESUMEN

Penetration into the female genital tract of infectious agents is associated with the cause of the onset of cervicitis. In most cases, these are sexually transmitted diseases (STDs). A high level of viral and bacterial load in the study of clinical material from women with infectious and inflammatory pathology (IVP) of the cervix affects the activity of innate immunity reactions. The total number of examined patients was 76 patients of reproductive age, of which 36 women with cervical IVP and 40 women made up the comparison group. The imbalance of microbiocenosis can be accompanied by immune and microbiological disorders. The aim of the study was to study immune and microbiological disorders in women with infectious and inflammatory pathology of the cervix. To achieve the goal, the following tasks were set: to identify the relationship between the expression level of TLR2 and TLR4 genes in the epithelial cells of the cervical canal of women in which UPM is determined. To determine the species spectrum and etiological significance of the microbiota of bacterial biofilm of the cervical mucosa in the pathogenesis of cervicitis in women of reproductive age. It has been established that the determination of indicators of innate immunity, such as interferons, in blood serum and the expression of TLR2 and TLR4 receptors, with the study of their balance, taking into account the pro-inflammatory and anti-inflammatory properties in IVP of the cervix, has an important prognostic value. An increase in the level of the immune response in the form of hyperstimulation of antigens of IVP pathogens leads to the chronization of the inflammatory process in the urogenital tract, to scarring of tissues, which can play an important role in the development of infertility and termination of pregnancy in women of reproductive age.

RESUMEN

Luohuazizhu suppository is a Traditional Chinese Medicine used in clinic to treat cervicitis, which is prepared from Callicarpa nudiflora Hook. et Arn (C. nudiflora), an herbal Chinese medicine named Luohuazizhu. This study aimed to figure out the active constituents of C. nudiflora and the potential mechanism for its anti-cervicitis effect. The ethanol extract in C. nudiflora (CNE) and the different fractions of CNE extracted by petroleum ether (CNE-p), dichloromethane (CNE-d), and n-butanol (CNE-b) were tested in vivo for their anti-cervicitis effects. Then the isolated compounds from the CNE-p were tested in vitro for their anti-inflammatory activities. The results displayed that CNE-p, CNE-d, and CNE-b exhibited adequate anti-cervicitis effects, with CNE-p showing the highest efficacy. Further experiment demonstrated that CNE-p could significantly inhibit the expression of NLRP3 in vitro. Six diterpenoids obtained from the CNE-p showed the ability to regulate inflammatory factor levels in vitro. Among these compounds, compounds 1 (callicarpic acid A) and 2 (syn-3,4-seco-12S-hydroxy-15,16-epoxy-4(18),8(17),3(16),14(15)-labdatetraen-3-oic acid) were the most effective agents, and they also inhibited the expression level of NLRP3 in vitro. The results confirmed that C. nudiflora has significant anti-cervicitis effects and the diterpenoids were most likely to be its active components. These data provide scientific support for the clinic usage of Luohuazizhu suppository and the development of new agents in treating cervicitis.

RESUMEN

The aim of the study was to improve the diagnosis of structural changes in all parts of the cervix depending on the preferential localization of the inflammatory process - in the ectocervix, endocervix, and also in the stroma in women with ectopia (pseudoerosis) of the vaginal part of the cervix. The study included women of predominantly early and middle reproductive age, as these women have inflammatory processes more often than in menopause. To perform the work, a transvaginal imaging method was used, which allowed us to see the smallest structures (up to 0.5-1.0 mm) of the cervix. We have previously developed a technique for visualizing the external part of the cervix and obtained a patent of Ukraine. The results of the ultrasound were compared with laboratory data, colposcopy and cervicoscopy. Traditionally, the diagnosis of cervicitis was made on the basis of clinical symptoms, smear results to determine the presence and type of pathogen. Endoscopic methods allowed visualization of only the mucous membrane of the cervical canal and external part of the cervix. The deep layers of the ectocervix, endocervix and cervical stroma can only be visualized using high-frequency ultrasound in a transvaginal way. According to the results of the study, it was possible to determine the preferential localization of the inflammatory process, to determine the nature of changes in different layers of the cervix. These changes were expressed in the presence of calcifications and cystic cavities of various sizes (1-6 mm), an increase or decrease in echogenicity, the degree of heterogeneity of the structure of the ecto-, endocervix and stroma.

RESUMEN

The aim of this study was to evaluate the effects of irreversible electroporation (IRE) on the uterine cervix in a rabbit model. IRE ablation was performed in the cervices of 48 New Zealand rabbits, with one ablation lesion in each animal. Gross pathology, transmission electron microscopy, hematoxylin and eosin (H&E), Masson's trichrome (MT) stain, and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assays were performed at pre-set time points (0 h, 12 h, 1 d, 2 d, 4 d, 7 d, 14 d, and 28 d post-IRE). All the rabbits tolerated the IRE ablation without serious complications. IRE caused complete cell death of the ablated cervix via cell apoptosis. However, fast recovery of the cervix was observed from 7 d post-IRE, with the signs of collagen fibers hyperplasia, the disappearance of the necrotic cells and muscle fibers, and regeneration and extension of the cervical epithelium. At 28 d post-IRE, the ablated cervices recovered to almost normal. Our study suggested that IRE might be an efficient and safe technology to treat cervical tumors, without causing serious cervical damage.

RESUMEN

PURPOSE: Most of the existing studies on postcoital bleeding (PCB) in Western countries. To date, no study has focused on the various PCB-related comorbidities in Taiwan women. This work aims to analyze and compare the presence or absence of PCB among Taiwanese women with gynecological comorbidity. METHODS: This study is a population-based retrospective cohort investigation. Outpatients with PCB after the index date were considered. A total of 2377 female patients with PCB (ICD-9 626.7) were identified using a nationwide outpatient sample from 2001 to 2010. For comparison, 7131 cases were randomly matched with the study group in terms of gender and age. RESULTS: The PCB incidence rate was 39-59 cases/100,000 Taiwanese women, with mean age (±SD) of 36.74 ± 10.79 years, median age of 36 years, and mode age of 29 years. Women with PCB exhibited 1.47-fold risk of cervical dysplasia and 1.59-fold risk for malignant neoplasm of cervix. Young women with PCB showed high risk of cervical cancer. The most common benign diseases among PCB- related comorbidities were cervical erosion and ectropion (20.66%), followed by vaginitis and vulvovaginitis (19.18%). Comparison between PCB and non-PCB groups indicated several significant high-risk comorbidities including cervical polyps, cervical erosion, leukoplakia of cervix, intrauterine contraceptive device, cervicitis, vaginitis, menopause, dyspareunia, and vulvodynia. CONCLUSIONS: This study provides evidence that PCB-related comorbidities manifested benign diseases (51.58%), lower genital tract infection (46.11%), and cervical cancer (2.31%). Thus, healthcare providers must ensure that appropriate routine screening tests and counseling are given to women with PCB.

RESUMEN

BACKGROUND: Mycoplasma genitalium is an emerging sexually transmitted pathogen implicated in inflammatory syndromes of the female reproductive tract. The objective of this study was to investigate human immunodeficiency virus (HIV)-infected women for an association between M. genitalium and cervicitis, a putative mechanism for enhanced HIV transmission efficiency to an uninfected partner. METHODS: Using a longitudinal cohort of antiretroviral therapy-adherent New Orleans women, we retrospectively screened for M. genitalium and quantitatively characterized several markers of cervical inflammation, including secreted cytokines and cytological and histological signs of leukocyte infiltration. RESULTS: We observed a high prevalence of M. genitalium (7.4%) among HIV-infected New Orleans women. Chronic M. genitalium infection was associated with increased secretion of proinflammatory cytokines, including interleukin 1ß, interleukin 6, and interleukin 8, and marked inflammatory cervical infiltrates in the cervix with enrichment of HIV target cells. Cure of M. genitalium infection resulted in ablation of all signs of inflammation. CONCLUSIONS: These findings implicate M. genitalium as an etiologic agent of cervicitis in HIV-infected women, providing a potential mechanism for enhanced HIV transmission to an uninfected partner. Screening and treatment of M. genitalium among HIV-infected individuals may be warranted to further understand this coinfection scenario, improve cervical health, and reduce the spread of HIV.

RESUMEN

Endocervicosis is considered a form of Mülleriosis affecting mainly the bladder and is comprised of endocervical-type glands and cysts. It has been rarely described in the uterine cervix where the extensive involvement of cervical and paracervical tissue poses the suspicion of malignancy, mostly minimal-deviation adenocarcinoma. We describe a case of cervical endocervicosis causing long-term symptoms leading to hysterectomy. We provide evidence that this pathology is associated with cesarean section similar with isthmocele. Its differential diagnosis is discussed.

RESUMEN

We present a case of a 30-year-old woman who, while undergoing infertility evaluation, was found to have a large cystic cervical mass, shown to be cystic cervicitis on cervical cone biopsy. Differential diagnosis for benign cystic cervical lesions includes Nabothian cysts, tunnel cluster, endocervical hyperplasia, and cervicitis, whereas cystic cervical malignancies include adenocarcinoma and adenoma malignum. While it is crucial to differentiate benign from malignant lesions, imaging characteristics often overlap and may not provide a specific diagnosis. In difficult cases, definitive diagnosis should be based on clinical presentation and cervical biopsy.

RESUMEN

BACKGROUND: This study was performed to evaluate the surface plasmon resonance-based (SPR) test with the W2600 System of GP Medical Technologies as a screening method for human papillomavirus (HPV) genotyping in China. METHODS: Between November 2012 and December 2013, the SPR test, hybrid capture II (HC2) test, and direct DNA sequencing assay were performed on 424 patients aged 22 - 65 years who attended the outpatient clinic at the Department of Obstetrics and Gynecology of West China Second University Hospital with diagnoses of chronic cervicitis or abnormal vaginal bleeding. Cervical specimens were collected from the cervical epithelia. Cytological and histological studies were also performed. RESULTS: A total of 424 patient specimens were screened. The positive, negative, and overall concordance between the SPR test and HC2 test was 93.48%, 89.16%, and 90.57%, respectively. The concordance between the SPR test and the direct DNA sequencing assay was 97.41%. Against the results of the direct DNA sequencing assay, the SPR test demonstrated a sensitivity of 96.86% and a specificity of 97.74%. CONCLUSIONS: The SPR test is reliable, sensitive, and specific for HPV genotyping. Compared to the hybrid-capture assay, the SPR test may work on more than one specimen at a time and is a low-cost, rapid, and easy-to-use method with the potential for automation. The SPR test may be widely employed in China and other countries for HPV genotyping.

RESUMEN

OBJECTIVES: Chronic nongonococcal nonchlamydial cervicitis is a condition of unknown etiology. Data about treatment options are limited. Our goal was to review a single center's experience in managing women with chronic NGNCC. METHODS: We evaluated all encounters at a tertiary care center with ICD-9 code for cervicitis between April 2008 and March 2014. Cases were defined by having two of the following 3 diagnostic criteria: mucopurulent discharge noted by (1) patient or (2) practitioner, and (3) cervical bleeding upon gentle probing. All women had negative nucleic acid amplification testing for Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis. Information regarding patient demographics, symptoms, findings, treatment, and outcomes were analyzed. Cure was defined as resolution of patient-specific diagnostic criteria. RESULTS: Sixty-one women were identified. The mean age was 31 years; 73.7% were white, and 59% were nulliparous. The mean duration of symptoms was 25.2 months. Initially, all 61 patients received one of 3 antibiotic treatments. The cure rate after initial antibiotic treatment was 65.6%. Nineteen patients required at least one further treatment. Additional treatments included secondary antibiotics, hormonal treatments, vaginal hydrocortisone, silver nitrate, cryotherapy, and loop excision electrosurgical procedure. Cure rates were as follows: 57.9% with antibiotics, 50% with hormone treatment, 0% with hydrocortisone, 100% with silver nitrate, 0% with cryotherapy, and 100% with loop electrosurgical excisional procedure. Of the initial 61 women, 93.4% were eventually cured. CONCLUSIONS: Nongonococcal nonchlamydial cervicitis is a condition that can cause unremitting symptoms. Most patients will respond to antibiotics, although other treatments including surgery may be necessary.

RESUMEN

Cervicitis is a common clinical finding often attributed to sexually transmitted infections (STIs), but no etiologic agent is identified in the majority of cases. In this study, we comparatively assessed inflammation among the common infectious etiologies of cervicitis and assessed the potential value of liquid cytology specimens for predicting STIs. Among 473 Louisiana women at low risk for acquiring STIs, the prevalences of Mycoplasma genitalium, Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis in liquid-based cytology specimens were 1.5, 2.1, 0.6, and 4.4%, respectively. N. gonorrhoeae and human papillomavirus 18 (HPV18) infections were significantly more common among subjects infected with M. genitalium. Using direct microscopy, we observed significant increases in leukocyte infiltrates among subjects with monoinfections with M. genitalium or C. trachomatis compared to women with no detectable STIs. Inflammation was highest among subjects with M. genitalium. Using a threshold of ≥ 2 leukocytes per epithelial cell per high-powered field, the positive predictive values for M. genitalium, C. trachomatis, N. gonorrhoeae, and T. vaginalis were 100, 70, 67, and 20%, respectively. Several novel M. genitalium genotypes were identified, all of which were predicted to be susceptible to macrolide antibiotics, suggesting that different strains may circulate among low-risk women and that macrolide resistance is substantially lower than in high-risk populations. This study highlights the capacity of M. genitalium to elicit cervical inflammation and, considering the strong epidemiologic associations between M. genitalium and human immunodeficiency virus (HIV), provides a potential mechanism for acquisition and shedding of HIV via chronic leukocyte recruitment to the cervical mucosa.

RESUMEN

The incidence of stage Ib~IIa of cervical adenocarcinoma accounts about 60 to 70% of all patients. This study aims to investigate the prognostic significance of protein estrogen receptor alpha (ERα) and transforming growth factor beta 1 (TGF-ß1) level in different glandular epithelia of the cervix. In this study, immunohistochemistry was used to detect ERα and TGF-ß1 in carcinomas and incisal margins of 66 cases with cervical adenocarcinoma, 20 cases with normal cervix, and 20 cases with chronic cervicitis. Uni- and multivariate analysis was applied to evaluate the prognostic significance of TGF-ß1 and ERα in carcinomas. The results indicated that the positive expression of TGF-ß1 in carcinomas was 71.21%, significantly higher compared to that in the normal cervix (35%) and chronic cervicitis (55%) (χ(2) = 8.901, P = 0.012). Similarly, the positive expression of ERα in the carcinomas was 68.18%, significantly higher compared to the normal cervix (35%) and chronic cervicitis (50%) (χ(2) = 7.693, P = 0.021). Both TGF-ß1 and ERα in the carcinomas were associated with the vaginal recurrence, infection of HPV, depth of infiltration, and lymphatic metastasis (P < 0.05). The conjugation of TGF-ß1 and ERα was an independent prognostic factor for cervical adenocarcinoma. Survival curve showed that the positive TGF-ß1 and ERα indicated a short lifetime of patient with cervical adenocarcinoma. In conclusion, the expression of TGF-ß1 and ERα protein in the carcinomas had a significant prognostic value in a patient of stage Ib~IIa in cervical adenocarcinoma.

RESUMEN

BACKGROUND: Ureaplasma parvum and Ureaplasma urealyticum are commonly found in the cervix of women with non-chlamydial and non-gonococcal cervicitis or non-specific cervicitis (NSC). However their contribution to the aetiology of NSC is controversial. METHODS: U. parvum and U. urealyticum were identified and quantified in cervical swabs collected from 155 women with NSC and 312 controls without NSC, using real-time PCR. The relative bacterial quantification was then calculated using the Ureaplasma copy number divided by the number of host cells; this is important for the correction of bias linked to the number of cells harvested in different swabs. RESULTS: Ureaplasma was detected in 58.7% (91/155) of NSC patients: U. parvum in 30.3%, U. urealyticum in 16.1%, and mixed infection in 12.3%. It was also detected in 54.5% (170/312) of controls: U. parvum in 33.0%, U. urealyticum in 11.5%, and mixed infection in 9.9%. There were no significant differences for U. parvum, U. urealyticum, or mixed infection between the 2 groups (p > 0.05). However, both biovars were present at higher concentrations in NSC patients than in controls (p < 0.05). Using >10 copies/1000 cells as a reference, the positive rate of U. parvum in NSC patients was 16.1%, significantly higher than that in controls at 5.1% (relative risk 3.145, p < 0.05); positive rates of U. urealyticum in NSC patients and controls were 28.4% and 8.7%, respectively, with a statistically significant difference (relative risk 3.131, p < 0.05). CONCLUSIONS: Ureaplasma can adhere to host cells, colonize, internalize, and subsequently produce pathological lesions. A high density of Ureaplasma in the cervix may be associated with the aetiology of NSC.

RESUMEN

Chlamydia trachomatis is among the most prevalent genital infections and is an important cause of tubal factor infertility. The majority of infected females are asymptomatic. Evidence on the reliability of signs of inflammation used to predict chlamydia in female patients is inconsistent. This study examined associations between criteria routinely used in many Scandinavian sexually transmitted infection (STI) clinics and a positive chlamydia test in a high-prevalence population. Clinical and microscopic signs of cervicitis and urethritis were recorded in 99 women attending due to chlamydia infection in a sexual partner. Mucopurulent cervical discharge, easily induced bleeding from the cervix, and more polymorpho-nuclear cells than epithelial cells in vaginal wet smear all correlated significantly with a positive Chlamydia trachomatis test (odds ratios: 3.4, 4.0 and 4.8, respectively). Increased numbers of polymorphonuclear leucocytes (>30 and ≥ 5 respectively) in stained cervical and urethral smears were not significantly correlated with chlamydia infection. Hence, routine collection of cervical and urethral smears in female STI patients is questionable.

RESUMEN

BACKGROUND: The Family Medical Program is a health care system in the Rio de Janeiro state. Women's health services offered by the Family Medical Program include preventive exams and screening, family planning, and prenatal follow-up. Although cervical cancer screening is offered, barriers to care still hinder the full success of the program, and we are attempting to identify these barriers. METHODS: We undertook a cross-sectional and prospective study involving 351 women who were referred to the Family Medical Program between March 2009 and November 2010. Demographic data were obtained through a structured household questionnaire. The dependent variable was defined as the non-realization of the Pap smear test following the protocol of the Health Ministry. Cervical samples for screening were collected after clinical examination. RESULTS: Women who had undergone Pap smear testing at least once every 3 years comprised 282 of the participants (80.3 %). Most of the women had normal or inflammatory cytology (96.3 %). Illiteracy and the absence of symptomatic episodes of sexually transmitted disease were independent barriers to having cancer screening at regular intervals. Illiterate women were more likely to be older, not to be using any contraceptive method, and on average had more than two children, more than four pregnancies, and more than two abortions. Embarrassment was the greatest barrier to seeking professional care reported by all women, regardless of level of educational attainment. Other important barriers to seeking care and/or screening included time constraints, due to work or childcare. CONCLUSION: This study indicates that the Family Medical Program effectively provides cervical cancer screening coverage for its eligible population, at the level mandated by the WHO and the Brazilian Health Ministry. Fully 96.3 % of the women in our study had normal or benign inflammation on cytology. Understanding of barriers to care-seeking behavior that limit program adherence is one way to facilitate communication between providers and patients regarding the benefits of cancer screening.

RESUMEN

OBJECTIVE: To investigate the perinatal outcomes of pregnant women with cervical intraepithelial neoplasia (CIN). METHOD: The women in this retrospective case-control study were recruited from Beijing Obstetrics and Gynecology Hospital from August 1, 2007 to February 28, 2010. All the cases were 13-32 gestational weeks, who were diagnosed by colposcopy conducted cervical biopsy. A total of 108 cases were followed-up to the day of delivery. RESULTS: (1) Complications of colposcopy conducted cervical biopsy: there were two cases of pregnant women, who suffered cervical local compression after undergoing colposcopy conducted cervical biopsy, as the bleeding could not be stopped, the wound was treated by local suture. The incidence of such event was 1.8% (2/108), without any colposcopy and biopsy-related adverse event. (2) Cesarean section rate was 63.6% (56/88) in CIN, which was higher than 30.0% (6/20) in cervicitis, and the cesarean section rate increased as CIN grades elevated, and gestational weeks of delivery advanced.(P < 0.05). (3) We did not detect significant difference for the incidence of polyhydramnios, premature rupture of fetal membranes, placental abruption, cervical laceration and postpartum hemorrhage, low birth weight infants, amniotic fluid II-III degree, neonatal deformity and neonatal asphyxia between pregnant women with CIN and cervicitis (P > 0.05); however, the incidence of oligohydramnios and premature infants in pregnant women with CIN group were higher than that in cervicitis group (P = 0.007; P = 0.020). (4) Vaginal delivery and HR-HPV infection did not increase the incidence of perinatal complication; the volume of postpartum hemorrhage within 2 h after birth in vaginal delivery was less than in cesearean section for pregnancies with CIN (P = 0.000). CONCLUSION: Pregnant women with CIN can be diagnosed by colposcopy conducted cervical biopsy, and they should be carefully monitored oligohydramnios and preterm during pregnancy. Pregnant women with CIN during pregnancy, excluding other obstetric operation indications may choose vaginal delivery first.

RESUMEN

OBJECTIVE: Human ß-defensin (hBD) is an innate immune mediator present in the mucosae. This study aimed to investigate whether hBD is implicated in nongonococcal cervicitis (NGC). MATERIALS AND METHODS: Seventy-two patients with NGC and 64 healthy volunteers were consecutively enrolled between April 2010 and May 2011. Sensitive antimicrobial treatment was assigned to patients with NGC. Cervical tissues were sampled for the semiquantitative reverse transcription-polymerase chain reaction analyses of hBD-1, hBD-2, and hBD-3 messenger RNA (mRNA) expression. RESULTS: The hBD-1, hBD-2, and hBD-3 mRNAs were comparably expressed in normal cervical tissues. The expression of hBD-1 mRNA was similar between patients with NGC and control subjects, whereas those of hBD-2 and hBD-3 mRNAs were significantly up-regulated in patients with NGC (1.25 [0.38] vs 1.08 [0.31], p = .005; 1.26 [0.35] vs 1.04 [0.30], p < .001). The relative expression level of hBD-1 mRNA remained unchanged in pathogen-eliminated patients, whereas those of hBD-2 mRNA (1.33 [0.42] vs 1.04 [0.36], p = .012) and hBD-3 mRNA (1.23 [0.32] vs 1.13 [0.26], p = .009) decreased significantly after the successful antimicrobial treatment. CONCLUSIONS: Expressions of hBD-2 and hBD-3 mRNA are up-regulated in NGC, suggesting the role of mucosal immunity in NGC.
