An investigation was carried out to determine the therapeutic effect of levofloxacin (LVFX) once-a-day oral therapy at the dose of 200 mg/day for 7 days on uterine cervicitis, in comparison with LVFX twice-a-day oral therapy at the dose of 200 mg/day for 7 days. Of the 102 patients enrolled in the study, 90 were subjected to the analysis. The efficacy rate on uterine cervicitis of the once-a-day therapy and twice-a-day therapy groups according to the evaluation of the Drug Efficacy Evaluation Committee were 72.0% (36/50) and 82.5% (33/40), respectively. The efficacy rate on uterine chlamydial cervicitis of the once-a-day therapy and twice-a-day therapy groups according to the evaluation of the Drug Efficacy Evaluation Committee were 88.0% (22/25) and 85.7% (18/21), respectively. Safety was evaluated as "safe" in 88 of the 90 assessable patients (97.8%). Side effects were seen in two cases, which belong to the once-a-day therapy group; mild candidiasis and mild breast distension sense. As the antimicrobial treatment started, the levels of the inflammatory cytokines, interleukin-6 (IL-6) and interleukin-8 (IL-8) in the cervical mucus, decreased. It is suggested that IL-6 and IL-8 can be useful indicators of the antimicrobial treatment in the uterine cervicitis. These results suggested that the LVFX once-a-day therapy can be useful on uterine cervicitis.

Women in Africa, especially young women, have very high human immunodeficiency virus (HIV) incidence rates that cannot be fully explained by behavioral risks. We investigated whether genital inflammation influenced HIV acquisition in this group.. Twelve selected cytokines, including 9 inflammatory cytokines and chemokines (interleukin [IL]-1α, IL-1β, IL-6, tumor necrosis factor-α, IL-8, interferon-γ inducible protein-10 [IP-10], monocyte chemoattractant protein-1, macrophage inflammatory protein [MIP]-1α, MIP-1β), hematopoietic IL-7, and granulocyte macrophage colony-stimulating factor, and regulatory IL-10 were measured prior to HIV infection in cervicovaginal lavages from 58 HIV seroconverters and 58 matched uninfected controls and in plasma from a subset of 107 of these women from the Centre for the AIDS Programme of Research in South Africa 004 tenofovir gel trial.. HIV seroconversion was associated with raised genital inflammatory cytokines (including chemokines MIP-1α, MIP-1β, and IP-10). The risk of HIV acquisition was significantly higher in women with evidence of genital inflammation, defined by at least 5 of 9 inflammatory cytokines being raised (odds ratio, 3.2; 95% confidence interval, 1.3-7.9; P = .014). Genital cytokine concentrations were persistently raised (for about 1 year before infection), with no readily identifiable cause despite extensive investigation of several potential factors, including sexually transmitted infections and systemic cytokines.. Elevated genital concentrations of HIV target cell-recruiting chemokines and a genital inflammatory profile contributes to the high risk of HIV acquisition in these African women.

To explore whether hypoxia and interleukin 8 (IL-8) regulate the viability and apoptosis of cervical carcinomas cells and the possible mechanism. We evaluated the expression of hypoxia inducible factor-1α (HIF-1α), IL-8 and its receptors (CXCR1 and CXCR2) in cervical cancer and cervicitis tissues by immunohistochemistry. Then the effects of hypoxia and IL-8 on the viability and apoptosis of HeLa and SiHa cells were detected by the SRB and apoptosis assays. Here we observed that the expression of HIF-1α, IL-8 and CXCR1 in cervical cancer tissues was significantly higher than that in cervicitis tissues. Hypoxic condition stimulated the secretion of IL-8 and the expression of CXCR1 and CXCR2 on HeLa and SiHa cells. Recombinant human IL-8 enhanced the viability and reduced the apoptosis in HeLa and SiHa cells. HeLa and SiHa cells cultured in 1% oxygen showed the increased viability and apoptosis, and the former effect could be partly reversed by anti-human IL-8 neutralizing antibody. This data suggested that IL-8 secreted by cervical carcinomas cells induced by hypoxia can stimulate the viability of cervical carcinomas cells in an autocrine dependent manner, and contribute to the pathogenesis of cervical cancer.

Cervical shedding of HIV-1 DNA may influence HIV-1 sexual transmission. HIV-1 DNA was detected in 250 (80%) of 316 and 207 (79%) of 259 cervical cytobrush specimens from 56 US and 80 Kenyan women, respectively. Plasma HIV-1 RNA concentration was associated with increased HIV-1 DNA shedding among US and Kenyan women. Kenyan women had higher cervicovaginal concentrations of proinflammatory interleukins (IL)-1β, IL-6, IL-8, and anti-inflammatory secretory leukocyte protease inhibitor compared with US women (all P < 0.01). HIV-1 DNA shedding was associated with increased concentrations of IL-1β and IL-6 and lower secretory leukocyte protease inhibitor among US women but not Kenyan women.

To investigate the relationship between local immune status of vagina and the occurrence of disease in patients with cervicitis.. ELISA were used to detect the level of interleukin (IL)-8 and tumor necrosis factor (TNF)alpha in vaginal douche of patients with cervicitis due to ureaplasma urealyticum, mycoplasma hominis, chlamydia trachomatis, neisseria gonorrhoeae and cervical erosion.. Compared with the control group, the level of IL-8 in vaginal douche of patients with mycoplasma hominis cervicitis, chlamydia trachomatis cervicitis and neisseria gonorrhoeae cervicitis was significantly higher and there was significant difference ng/L: 371 +/- 34, 369 +/- 31, 339 +/- 36, vs 341 +/- 32, 338 +/- 33, 316 +/- 24, (all P < 0.01). Comparing the level of IL-8 in vaginal douche of patients with ureaplasma urealyticum cervicitis and cervical erosion with that of control group, there was no statistical difference (all P > 0.05). The level of TNF-alpha in vaginal douche of each group was remarkably higher than that of control group except for patients with cervical erosion. And statistically significant difference was found between them (all P < 0.01).. With regards to the pathogenesis of cervicitis, local immune mechanism of vagina plays an important role in the occurrence of cervicitis. The role of IL-8 in pathogenesis of mycoplasma hominis cervicitis, chlamydia trachomatis cervicitis and neisseria gonorrhoeae cervicitis is likely to be more important.

The female genital tract is the major route of heterosexual human immunodeficiency virus (HIV) acquisition and transmission. Here, we investigated whether HIV-specific CD8 T-cell-mediated immune responses could be detected in the genital mucosa of chronically HIV-infected women and whether these were associated with either local mucosal HIV shedding or local immune factors. We found that CD8(+) T-cell gamma interferon responses to Gag were detectable at the cervix of HIV-infected women but that the magnitude of genital responses did not correlate with those similarly detected in blood. This indicates that ex vivo HIV responses in one compartment may not be predictive of those in the other. We found that increased genital tumor necrosis factor alpha (TNF-alpha) and interleukin-10 (IL-10) levels correlated significantly with levels of Gag-specific CD8(+) T cells at the cervix. Women who were detectably shedding virus in the genital tract had significantly increased cervical levels of TNF-alpha, IL-1beta, IL-6, and IL-8 compared to women who were not detectably shedding virus. We were, however, unable to detect any association between the magnitude of cervical HIV-specific responses and mucosal HIV shedding. Our results support the hypothesis that proinflammatory cytokines in the female genital tract may promote HIV replication and shedding. In addition, we further show that inflammatory cytokines are associated with increased levels of HIV-specific CD8 effector cells at the genital mucosa but that these were not able to control genital HIV shedding.

The aim of this study was to estimate: the frequency of aerobic vaginitis, susceptibility of the GBS isolated from vagina of non-pregnant women with and without cervicitis to selected antibiotics and chemotherapeutics and the proinflammatory cytokines production by HeLa, THP-I, U - 937 cells after stimulation by vaginal GBS. Our results indicated low frequency of the aerobic vaginitis -4.5% among non-pregnant young women and ability of the vaginal GBS to release proinflammatory cytokines by human cell lines in vitro.

To evaluate concentrations of interleukin (IL)-6, IL-8, lactoferrin (LF), and alpha defencine (alpha-DF) in the cervical mucus of pregnant women and analyze their relation to cervicitis and bacterial vaginosis (BV).. Cervical mucus samples were obtained from August 2003 through May 2004 from 157 women who were between the 6th and 36th week of an uncomplicated singleton pregnancy. All women were delivered at term, 69 without BV or cervicitis, 9 with BV, and 79 with cervicitis.. Interleukin 8, LF, and mu-DF concentrations were higher in women with cervicitis (0.81 +/- 0.36 pg/mL, 14.8+/-12.3 microg/mL, and 0.60 +/- 0.49 microg/mL) than in women without BV or cervicitis (0.35 +/- 0.34 pg/mL, 8.0 +/- 11.0 microg/mL, and 0.15 +/- 0.12 microg/mL). Interleukin 6 concentration was higher in women with BV (0.26 +/- 0.32 pg/mL) than in women without BV or cervicitis (0.09 +/- 0.15 pg/mL) or in women with cervicitis (0.12 +/- 0.18 pg/mL).. Higher levels of inflammatory cytokines in the cervical mucus of pregnant women may lead to early detection of lower genital tract infection.

Intra-amniotic infection, diagnosed by microbial invasion of the amniotic cavity (MIAC) and/or the presence of intra-amniotic inflammation (IAI), is related to adverse perinatal outcome in women with preterm labor. Due to the subclinical nature of IAI, a correct diagnosis depends on amniocentesis, which is an invasive method not performed as a clinical routine. The aim of this study was to evaluate if cervical length measured by transvaginal sonography could assist in the identification of women at high risk for IAI.. Cervical length was assessed by transvaginal sonography in 87 women with singleton pregnancies in preterm labor (<34 weeks of gestation). Cervical (n=87) and amniotic (n=55) fluids were collected. Polymerase chain reactions for Ureaplasma urealyticum and Mycoplasma hominis, and culture for aerobic and anaerobic bacteria, were performed. Interleukin (IL)-6 and IL-8 were analyzed by enzyme-linked immunosorbent assay.. IAI was present in 25/55 (45%) of the patients presenting with preterm labor who underwent amniocentesis. Women with IAI had a significantly shorter cervical length (median, 10 (range, 0-34) mm) than had those without IAI (median, 21 (range, 11-43) mm) (P<0.0001). Receiver-operating characteristics curve analysis showed that a cervical length (cut-off of 15 mm) predicted IAI (relative risk, 3.6; CI, 1.9-10.0) with a sensitivity of 72%, specificity of 83%, positive predictive value of 78% and negative predictive value of 78%. Cervical length was also significantly associated with preterm birth up to 7 days from sampling and at
