[unfortunately without effectiveness: chlamydia eradication after infarct]. 200212014269
mycoplasma pneumoniae and chlamydia pneumoniae cause lower respiratory tract disease in paediatric patients.new studies suggest that mycoplasma pneumoniae and chlamydia pneumoniae play a more significant role as causes of lower respiratory tract infections in childhood than was previously thought. in particular, the incidence of infections caused by these pathogens is high in children aged less than 5 years, the infections themselves seem to be a possible cause of wheezing, and may present a more complicated course when not treated with adequate antimicrobial agents. however, despite the increasing pa ...200212015465
chlamydia pneumoniae infection of endothelial cells induces transcriptional activation of platelet-derived growth factor-b: a potential link to intimal thickening in a rabbit model of atherosclerosis.smooth muscle cell (smc) proliferation and intimal thickening are hallmark features of atherosclerotic disease, and chlamydia pneumoniae may contribute to atherogenesis by imparting biological effects on smcs. an in vitro endothelial cell model and a normocholesterolemic rabbit model were used to test the hypothesis that infection with c. pneumoniae induces smc growth factor production, smc proliferation, and aortic intimal thickening. using reverse-transcriptase polymerase chain reaction, it wa ...200212023768

parachlamydiaceae: potential emerging pathogens.parachlamydiaceae, which naturally infect amoebae, form a sister taxon to the chlamydiaceae on the basis of the chlamydia-like cycle of replication and 80% to 90% homology of ribosomal rna genes. because intra-amoebal growth could increase the virulence of some intracellular bacteria, parachlamydiaceae may be pathogenic. arguments supporting a pathogenic role are that chlamydia pneumoniae, a well-recognized agent of pneumonia, was shown to infect free-living amoebae and that another member of th ...200212023921
species specific chlamydiae antibodies in voluntary blood donors of delhi.different species of genus chlamydia have been associated with ocular, genitourinary and respiratory infections, and coronary artery disease. since the majority of these infections remain asymptomatic or subclinical, antibodies may be present in apparently healthy individuals, and the determination of species specific chlamydia antibodies in a healthy population may reflect exposure. we therefore screened the sera of healthy blood donors for species specific chlamydia antibodies by microimmunofl ...200112025256

chlamydia pneumoniae and hyperlipidemia are co-risk factors for atherosclerosis: infection prior to induction of hyperlipidemia does not accelerate development of atherosclerotic lesions in c57bl/6j mice.chlamydia pneumoniae has been shown to accelerate atherosclerotic lesion development in hyperlipidemic animals. this study showed that c. pneumoniae did not accelerate lesion development in mice if a high-fat/high-cholesterol diet was started after infection, indicating that c. pneumoniae is a co-risk factor with hyperlipidemia for cardiovascular disease.200212183595
[chlamydia pneumoniae infections--diagnostic methods].gram-negative bacteria chlamydia pneumonia was found in 1989 to cause acute and chronic respiratory tract infections. this agent has been as well associated with other disease: atherogenesis and coronary heart disease. this study is aimed both at making an introduction to the issues related to c. pneumoniae diagnosis and presenting contemporary laboratory methods. given the limitations of traditional diagnostics methods, serodiagnosis (eia) and nucleic acids amplification (pcr, hybridisation) pr ...200212184026
[chlamydia pneumoniae infection and multiple sclerosis].possible association of chlamydia pneumoniae and multiple sclerosis is the subject of recent interest. the findings concerning the isolation of the agent from csf and tissue from postmortem brain are controversial, similarly as absorption of oligoclonal bands in csf by this antigen. the hypothesis should be further studied to establish whether an association of ch. pneumoniae with ms exists or not.200212185805
immune activation as effect modifier of atherogenesis in chronic infection.although no study has proven that infections cause atherosclerotic disease, findings suggest that exposure to infections such as chlamydia pneumoniae, helicobacter pylori, and bacterial infections related to periodontal disease or smoking might influence the development of heart, carotid, and peripheral vascular disease. epidemiological data convincingly demonstrate risk for atherosclerotic disease associated with bacterial infection and endotoxemia; however, the independent contributions to dis ...200212187843
could an infectious trigger explain the differential maternal response to the shared placental pathology of preeclampsia and normotensive intrauterine growth restriction?preeclampsia/eclampsia remains an important cause of maternal and perinatal morbidity and mortality. its origins lie in a mismatch between fetoplacental demands and the ability of the uteroplacental arteries to supply those demands, a situation that also arises in normotensive intrauterine growth restriction (the fetal syndrome of preeclampsia in isolation). why is there this differential response to the same underlying pathology? this review summarises the evidence surrounding a potential trigg ...200212190839
prevalence, rate of persistence and respiratory tract symptoms of chlamydia pneumoniae infection in 1211 kindergarten and school age children.is a common cause of respiratory disease, but little is known about asymptomatic infection, duration of persistent respiratory tract infection and seasonal changes of prevalence in a normal large sample size pediatric population.200212192165
[autoantibodies and anti-factor viii and chlamydia pneumoniae infection].we report the case of a 64-year-old man without hemorrhagic history experiencing epistaxis. the standard hemostasis assessment including prothrombin index, activated partial thromboplastin time (aptt) and platelet count found an isolated abnormal aptt (105 sec vs 33 sec). therefore, coagulation factors were explored. an acquired factor viii deficiency (5%) with anti-fviii antibody (4.5 bethesda unit.ml-1) was recognised. this anti-fviii antibody was related to a chlamydia pneumoniae pulmonary in ...200212192696
multiple chlamydia pneumoniae antigens prime cd8+ tc1 responses that inhibit intracellular growth of this vacuolar pathogen.cd8(+) t cells play an essential role in immunity to chlamydia pneumoniae (cpn). however, the target ags recognized by cpn-specific cd8(+) t cells have not been identified, and the mechanisms by which this t cell subset contributes to protection remain unknown. in this work we demonstrate that cpn infection primes a pathogen-specific cd8(+) t cell response in mice. eighteen h-2(b) binding peptides representing sequences from 12 cpn ags sensitized target cells for mhc class i-restricted lysis by ...200212193722

proinflammatory cytokines, antibodies to chlamydia pneumoniae and age-associated diseases in danish centenarians: is there a link?plasma levels of tumour necrosis factor (tnf)-alpha levels increase with age. high levels are associated with dementia and atherosclerosis in centenarians. chlamydia pneumoniae induces the production of proinflammatory cytokines and has been related to the pathogeneses of alzheimer's disease and cardiovascular diseases. the purpose of this study was to test the hypothesis that circulating levels of tnf-alpha represent a link between c. pneumoniae, high prevalences of dementia and cardiovascular ...200212195874
[chlamydia pneumoniae and acute respiratory tract infections in breast-feeding infants: simultaneous mother-child serological study in niamey (niger)].the age and the origin of chlamydia pneumoniae primary infection in sahelian areas are unknown. to evaluate the prevalence of c. pneumoniae antibodies, the authors studied the serological status of c. pneumoniae-, c. psittaci- and c. trachomatis-specific antibodies of 50 mother-child couples using the microimmunofluorescence technique. children were 10 to 34 month-old (18,1 6,2, mean sd), breast-fed and hospitalized with acute respiratory tract infections in niamey (republic of niger). speci ...200212196294
association of chlamydia pneumoniae with coronary artery disease and its progression is dependent on the modifying effect of mannose-binding lectin.the possible association between coronary artery disease (cad) and chlamydia pneumoniae (c pneumoniae) infection is controversial. on the basis of the recent suggestion that mannose-binding lectin (mbl) variant alleles are related to an increased risk of severe atherosclerosis, and on the in vitro interaction of mbl with c pneumoniae, we asked whether mbl might contribute to cad in conjunction with c pneumoniae.200212196331
[the role of infection and inflammation in the pathogenesis of atherosclerosis].pathogenesis of the atherosclerotic process is deemed as multifactorial. to the most important risk factors, besides certain family predisposition, there belongs hypercholesterolemia, arterial hypertension, obesity, diabetes mellitus, smoking and others. in the last years there are more and more data about the role of inflammation and infection in the whole development of atherosclerosis. the witness for this hypothesis is the findings of high parameters of inflammation in involved vessels as we ...200212197410
chlamydia pneumoniae seropositivity and early carotid atherosclerosis in a suburban japanese population.to evaluate the association between chlamydia pneumoniae (c. pneumoniae) infection and carotid atherosclerosis (ca), we investigated ca assessed by carotid b-mode ultrasound and known or suspected atherosclerotic risk factors including c. pneumoniae igg and iga antibodies in 2410 residents (mean age 54.5+/-13.6 years, 697 men) of a suburban japanese town. ca was found in 30.1% of men and in 14.0% of women, igg in 59.4% and in 51.4%, and iga in 36.9% and in 32.4%, respectively. in univariate anal ...200212204803
comparative in vitro activity of garenoxacin against chlamydia spp.the in vitro susceptibilities of 33 isolates of chlamydia trachomatis, chlamydia pneumoniae and chlamydia psittaci to a new quinolone drug, garenoxacin (bms-284756), in comparison with levofloxacin, ciprofloxacin, doxycycline, erythromycin and roxithromycin, were determined. garenoxacin was the most active of the quinolone drugs tested, with identical mic and mbc, which ranged from 0.007 to 0.03 mg/l. the mic and mbc of the other two quinolones tested, levofloxacin and ciprofloxacin, were also i ...200212205067
[role of viral infections and chlamydia pneumoniae and mycoplasma pneumoniae infections in asthma in infants and young children. epidemiologic study of 118 children].wheezing associated with upper respiratory tract infections is common in children. using conventional techniques (viral culture and immunofluorescence) and molecular techniques (pcr), we studied the prevalence of viral, chlamydia pneumoniae (cp) and mycoplasma pneumoniae (mp) infections in 118 children hospitalised for acute asthma exacerbation. a virus was identified by conventional techniques in 40 of the 118 nasal swabs (34%), while pcr allowed identification of virus cp and mp in 80 samples ...200212205810
[cardiovascular prevention: new biochemical plasmatic markers of risk].the primary prevention of acute coronary syndromes is an open question. the scientific progress has discovered new biochemical markers of cardiovascular disease risk that may be useful for primary prevention. they are plasmatic markers of inflammation (serum amyloid a, c-reactive protein, phospholipase a2) and of infection (seropositivity to chlamydia pneumoniae, cytomegalovirus). they are plasmatic markers of endothelial activation (adhesion molecules such as icam-1, vcam-1) immunological marke ...200212207197
role of chlamydial heat shock protein 60 in the stimulation of innate immune cells by chlamydia pneumoniae.chlamydia pneumoniae stimulates potently maturation of and cytokine secretion by bone marrow-derived dendritic cells (bmddc). bmddc responses depend mainly on toll-like receptor (tlr)2 and to a minor extent on tlr4. we demonstrate here using c. pneumoniae in an infectious model with the replication-permissive epithelial cell line hep2 that hsp60 is produced in substantial amounts in chlamydial inclusions during infection. electron microscopy of chlamydial inclusions revealed that hsp60 was mainl ...200212207330
chlamydia pneumoniae activates ikk/i kappa b-mediated signaling, which is inhibited by 4-hne and following primary exposure.chlamydia pneumoniae may be involved in atherosclerosis by inducing inflammation as well as ldl oxidation. the transcription factor nf-kappa b is found in an active state in atherosclerotic lesions. this study examined the effect of c. pneumoniae exposure on the nf-kappa b system in human monocytic lineage cells. short exposure to c. pneumoniae as well as chlamydial heat shock protein 60 activated nf-kappa b, accompanied by increased cytokine production. incubation with c. pneumoniae-induced dep ...200212208473
effect of treatment for chlamydia pneumoniae and helicobacter pylori on markers of inflammation and cardiac events in patients with acute coronary syndromes: south thames trial of antibiotics in myocardial infarction and unstable angina (stamina).infection with helicobacter pylori and chlamydia pneumoniae is associated with coronary heart disease. we conducted an intervention study using antibiotics against these bacteria in patients with acute coronary syndromes to determine whether antibiotics reduce inflammatory markers and adverse cardiac events.200212208796
chlamydophila pneumoniae infection of human aortic endothelial cells induces the expression of fc gamma receptor ii (fcgammarii).chronic endothelial infection is believed to be one of the factors able to cause endothelial cell damage and trigger the onset of human atherosclerosis. chlamydophila pneumoniae infects endothelial cells and has received special attention because of both epidemiological and experimental evidence supporting its role as a risk factor for atherosclerosis. it is also possible that otherwise independent risk factors for atherosclerosis may have synergistic effects. immune phenomena, such as the forma ...200212217337
