PROBLEM Infection of human fetal membranes elicits secretion of pro-inflammatory modulators through its innate immune capacities. We investigated the effect of lipopolysacharide (LPS) and progesterone (P4) upon expression of TLR-4/MyD88, TNFα, IL-6, IL-8, IL-10, and HBD2 on the human amniotic epithelium. METHOD OF STUDY Explants of the human amniotic(More)
OBJECTIVE Interleukin (IL)-10 is a cytokine with anti-inflammatory properties that plays pivotal roles in immune recognition and maintenance of pregnancy, limiting the harmful effects of pro-inflammatory modulators. The aim of this work was to characterize the contribution of amnion and choriodecidua regions of the human fetal membranes in the production of(More)
BACKGROUND During intrauterine infection, amniochorionic membranes represent a mechanical and immunological barrier against dissemination of infection. Human beta defensins (HBD)-1, HBD-2, and HBD-3 are key elements of innate immunity that represent the first line of defense against different pathogen microorganisms associated with preterm labor. The aim of(More)
The authors report a nosocomial infection outbreak by Klebsiella pneumoniae, observed in neonates at a gyneco-obstetrical hospital from Mexico City. Forty six newborns presented one or more infections due to K. pneumoniae during their stay in neonatal care units, between October 3 and November 12, 1988. Sepsis was documented in 41 cases by clinical picture(More)
The anaerobic bacteria (AB) are between the most numerous microorganisms (mo) that constitute the flora of the female genital tract, so they can participate in the etiology of obstetric and gynecologic infections (OGI). The objective of this study was to investigate the frequency of AB isolations and the clinical characteristics of the anaerobic infections(More)
A higher than 350 eosinophils/mm(3) is strongly associated with Chlamydia trachomatis in term born babies coursing with respiratory distress. However, in preterm newborns infected with this pathogen, the levels of eosinophils are unknown. Forty newborn infants with clinical data of respiratory problems and/or sepsis were analyzed. DNA of leukocytes from(More)
INTRODUCTION Escherichia coli is recognized as an etiological bacteria associated with chorioamnionitis and the preterm premature rupture of fetal membranes. This pathological condition induces pro-inflammatory cytokines and degradative metalloproteinases, which are considered biological markers secreted in an acute stage of infection. Heat-shock proteins(More)
BACKGROUND In the United States 19 million people acquire a sexually transmitted disease every year. Sexually transmitted diseases impact in gynecological terms because they may cause sterility, infertility and ectopic pregnancy. OBJECTIVE To compare the effectiveness of two combinations of three oral antimicrobial drugs in the treatment of mixed(More)
