chlamydia pneumoniae, asthma, and copd: what is the evidence?reading this article will familiarize the reader with (1) the unique chlamydial intracellular life cycle and the propensity for human chlamydial infections to become persistent and to result in immunopathologic (inflammatory) damage in target organs and (2) current evidence linking chlamydia pneumoniae (cpn) infection to obstructive lung diseases (asthma and chronic obstructive pulmonary disease, copd). potential therapeutic implications of the cpn-asthma association are also discussed.199910541419
analysis of the humoral immune response to chlamydia pneumoniae by immunoblotting and immunoprecipitation.chlamydia pneumoniae is a widely spread agent of respiratory tract infections in humans. a reliable serodiagnosis of the disease is hampered by the poor knowledge about immunodominant antigens in c. pneumoniae infections. we applied a novel strategy to identify immunogenic proteins of c. pneumoniae tw183 combining metabolic radiolabeling of de novo-synthesized chlamydial antigens with immunoprecipitation. by this technique c. pneumoniae antigens of approximately 160, 97 to 99, 60 to 62, 40, 27, ...199910548570
can an antibiotic (macrolide) prevent chlamydia pneumoniae-induced atherosclerosis in a rabbit model?there is increasing data implicating chlamydia pneumoniae in the pathogenesis of atherosclerosis, and antibiotics may theoretically be useful to prevent secondary vascular complications. three groups of new zealand white specific-pathogen-free rabbits, fed cholesterol-free chow, were inoculated via the nasopharynx on three occasions, 2 weeks apart, with c. pneumoniae. group i (n = 23) rabbits were untreated; group ii (n = 24) rabbits were treated with azithromycin at 30 mg/kg of body weight dail ...199910548582
sézary t-cell activating factor is a chlamydia pneumoniae-associated protein.we previously identified a protein that was stimulatory for malignant sézary t cells, termed sézary t-cell activating factor (saf). however, the identity of this protein has not been fully elucidated, nor has it's role been determined in the pathogenesis of cutaneous t-cell lymphoma (ctcl). the basis for epidermotropism and proliferation of malignant cells in the skin of patients with ctcl is unknown. using a monoclonal antibody inhibitory for saf activity, we demonstrated that saf is present in ...199910548583

[persistence of chlamydia pneumoniae in coronary plaque tissue. a contribution to infection and immune hypothesis in unstable angina pectoris].there is an increasing number of pointers towards a causative connection between chlamydia pneumoniae and atherosclerosis. but the pathogenetic mechanism and intimal structures that are involved remain unclear. starting with the hypothesis of a chronic infection, as demonstrated by the presence of the chlamydial stress (heat-shock) protein 60 (hsp 60), the presence and localization of these bacterial products in coronary atheromas was investigated.199910605420
multiplex pcr for rapid and differential diagnosis of mycoplasma pneumoniae and chlamydia pneumoniae in respiratory infections.a duplex polymerase chain reaction (pcr) was developed for the simultaneous detection of chlamydia pneumoniae and mycoplasma pneumoniae. a study of 163 respiratory specimens from in-patients of the "centre hospitalier et universitaire de nancy" showed the good sensitivity of this duplex pcr allowing the detection of c. pneumoniae and m. pneumoniae from 8 and 13 patients, respectively, whereas the culture was negative for c. pneumoniae for all the samples and positive for m. pneumoniae only in 9 ...199910579089
characterization of low-density lipoprotein uptake by murine macrophages exposed to chlamydia pneumoniae.exposure to chlamydia pneumoniae is correlated with atherosclerosis in a variety of clinical and epidemiological studies, but how the organism may initiate and promote the disease is poorly understood. one pathogenic mechanism could involve modulation of macrophage function by c. pneumoniae. we recently demonstrated that c. pneumoniae induces macrophages to accumulate excess cholesterol and develop into foam cells, the hallmark of early atherosclerotic lesions. to determine if c. pneumoniae-indu ...199910602673
computational analysis of the polymorphic membrane protein superfamily of chlamydia trachomatis and chlamydia pneumoniae.whole sequence genome analysis is invaluable in providing complete profiles of related proteins and gene families. the genome sequences of the obligate intracellular bacteria chlamydia trachomatis and chlamydia pneumoniae both encode proteins with similarity to several 90-kda chlamydia psittaci proteins. these proteins are members of a large superfamily, c. trachomatis with 9 members and c. pneumoniae with 21 members. all polymorphic membrane protein (pmp) are heterogeneous, both in amino acid s ...199910587946
serological evidence of chlamydia pneumoniae lipopolysaccharide antibodies in atherosclerosis of various vascular regions.the role of chlamydia pneumoniae in the pathogenesis of atherosclerosis has so far mainly been investigated in patients suffering from coronary heart disease; the other vascular regions have virtually been ignored. the aim of this study was to carry out a statistical survey of serological markers of a c. pneumoniae infection in patients with different patterns of atherosclerosis manifestation.199910611843

association of serology with the endovascular presence of chlamydia pneumoniae and cytomegalovirus in coronary artery and vein graft disease.chemotherapeutic treatment for patients with symptomatic coronary artery disease to reduce cardiovascular events may be initiated in response to elevated antibody titers against chlamydia pneumoniae or cytomegalovirus. how antibody titers are associated with the endovascular presence of these microorganisms is still unclear.200010637199
[acute respiratory chlamydia pneumoniae infections in adults. value of direct gene amplification diagnosis].chlamydia pneumoniae has been established recently as an important human respiratory pathogen. the aim of this study was to define the incidence of chlamydia pneumoniae in acute respiratory infections by evaluating its presence in posterior nasopharyngeal aspirates or broncho-alveolar lavage specimens by polymerase chain reaction-hybridization (pcr-eia) as well as the titres of specific antibodies in serum by a relisa test and a micro-immunofluorescence (mif) test. 68 adults patients were invest ...199910637911
helicobacter pylori, chlamydia pneumoniae, and cytomegalovirus: chronic infections and coronary heart disease.we conducted a medline search of the english-language literature from 1966-1999 on the association of chronic infections with helicobacter pylori, chlamydia pneumoniae, and cytomegalovirus (cmv) with coronary heart disease (chd); additional literature was retrieved from references of selected articles. all human studies were included. abstracts were excluded because of limited data. chronic infections in chd are speculated to be due to serum antibody concentrations of one or more of the three or ...200010641975
[chlamydia pneumoniae and atherosclerosis].there is widespread consensus that atherosclerosis is an inflammatory disease. between possible pathogenetic mechanisms, infective hypothesis has received increasing attention. researches have recently focused their attention on the role of chlamydia pneumoniae, a gram-negative intracellular organism, as infection by this bacterium has been demonstrated frequently associated with atherosclerosis. this review attempts to analyze and critically evaluate available data of the literature about the a ...199910638018
identification of an antigen localized to an apparent septum within dividing chlamydiae.the process of chlamydial cell division has not been thoroughly investigated. the lack of detectable peptidoglycan and the absence of an ftsz homolog within chlamydiae suggest an unusual mechanism for the division process. our laboratory has identified an antigen (sep antigen) localized to a ring-like structure at the apparent septum within dividing chlamydial reticulate bodies (rb). antisera directed against sep show similar patterns of antigen distribution in chlamydia trachomatis and chlamydi ...200010639437
acquired immunity to chlamydia pneumoniae is dependent on gamma interferon in two mouse strains that initially differ in this respect after primary challenge.the role of gamma interferon (ifn-gamma) in a chlamydia pneumoniae mouse model was studied by in vivo neutralization in two inbred mouse strains. during primary c. pneumoniae infection, neutralization of ifn-gamma increased both the numbers of bacteria and the pneumonia score in the lungs of c57bl/6 mice but not balb/c mice. during reinfection, the bacterial counts in the lungs were increased by ifn-gamma neutralization in both mouse strains. thus, the effect of ifn-gamma neutralization was depe ...200010639472

[role of chlamydia pneumoniae in the pathogenesis of coronary disease].several studies have demonstrated an association chlamydia pneumoniae with coronary artery disease, suggesting that infection with c. pneumoniae increases the risk for coronary artery disease by factor 2 or more. since atherosclerosis is considered to be a chronic inflammatory process, these data would fit into the response-to-injury hypothesis of atherosclerosis rather than representing a completely novel concept. several pathomechanisms as increased cytokine synthesis, proliferative and proagg ...199910643056
effect of a mycoplasma hominis-like mycoplasma on the infection of hep-2 cells by the tw-183 strain of chlamydia pneumoniae.we isolated a mycoplasma hominis-like mycoplasma from a stock culture of chlamydia pneumoniae tw-183 obtained from the american type culture collection and eradicated the contaminant by treating the stock suspension with a nonionic detergent, igepal ca-630. the m. hominis-like mycoplasma neither inhibits nor enhances the infectivity of c. pneumoniae for hep-2 cells.200010655399
failure to detect chlamydia pneumoniae in brain sections of alzheimer's disease patients.a recent north american study detected chlamydia pneumoniae in 17 of 19 brains of alzheimer's patients and supposed a c. pneumoniae infection to be a risk factor for alzheimer's disease (ad). in this study, we analyzed paraffin-embedded tissue samples of 20 ad patients by nested pcr and immunocytochemistry with a panel of antichlamydial antibodies and could detect neither c. pneumoniae-specific dna nor chlamydial antigens. from our data, the presence of c. pneumoniae in the brains of alzheimer's ...200010655406
[chlamydia pneumoniae infection and mycoplasma pneumoniae infection in pediatric patients].we evaluated a total of 1104 pediatric patients with acute lower respiratory tract infection for c. pneumoniae infection and m. pneumoniae infection by serology during july 1995 to december 1998. a microimmunofluorescence test was used for diagnosis of c. pneumoniae infection and a high density particle agglutination test for that of m. pneumoniae infection. acute c. pneumoniae infection was found in 149 patients (13.5%), acute m. pneumoniae infection in 118 patients (10.7%), and dual infection ...199910655676
association of chlamydia pneumoniae infection with diabetic nephropathy.we evaluated the association of chlamydia pneumoniae (cp) infection with progression of diabetic nephropathy. type 2 diabetic patients (60) were divided into two groups, those with incipient nephropathy and those with advanced nephropathy, based on the severity of diffuse glomerular lesions using gellman's criteria. type 2 (34) diabetic patients without nephropathy (normoalbuminuria) and 59 nondiabetics served as control groups. serum igg-antibody against cp was measured using elisa. cp antibody ...200010660220

[infections with chlamydia pneumoniae, helicobacter pylori or cytomegalovirus and atherosclerosis].it's known that common risk factors of atherosclerosis can explain only 50% of its etiology. in only 40% patients risk factors modification inhibits progression of atherosclerosis. therefore looking for new risk factors of atherosclerosis is necessary. in recent years the inflammatory-infectious hypothesis of atherosclerosis has been reevaluated. the discovery of heavy infections load in the serum of patients with acute coronary syndromes might suggest a potential immunological mechanism trigger ...199910695364
seroprevalence of chlamydia pneumoniae antibodies in a young adult population sample living in verona. european community respiratory health survey (ecrhs) verona.the aim of the study was to evaluate the prevalence of antibodies to chlamydia pneumoniae in a random population sample of 369 young adults (aged 20-44 years), living in verona, italy. igg and igm titers were measured by micro-immunofluorescence. igg antibodies, greater or equal to 16, were found in 104/177 (58.8%) men and 76/192 (39.6%) women (p < 0.001). no relationship was found between igg seropositivity, age, social class, education and family size. factors positively associated with igg se ...200010697790
serological evidence of infection with chlamydia pneumoniae is related to the severity of asthma.there is evidence that infection with chlamydia pneumoniae is associated with asthma of recent onset and that it can influence the severity of asthma. this has led to the suggestion that macrolide antibiotics may be useful in the treatment of asthma in subjects infected with c. pneumoniae. this study examined the association between immunoglobulin (ig)g and iga titres to c. pneumoniae and the severity of asthma. igg and iga antibodies to c. pneumoniae were measured in 619 subjects with asthma (1 ...200010706488

expression of secretory group iia phospholipase a(2) in relation to the presence of microbial agents, macrophage infiltrates, and transcripts of proinflammatory cytokines in human aortic tissues.recent seroepidemiological and immunohistochemical studies have demonstrated an association between microbial infections and atherosclerosis. however, the mechanisms underlying this association are widely unknown. in the present study, arterial specimens obtained at autopsy after sudden death were analyzed concerning (1) the presence of chlamydia pneumoniae, cytomegalovirus, herpes simplex virus, and helicobacter pylori; (2) the expression of secretory group iia phospholipase a(2) (spla(2)-iia) ...200010712401
detection of sequence variation in pcr-amplified fragments of omp2 gene from three species of the family chlamydiaceae using agarose gel electrophoresis containing bisbenzimide-peg.a simple technique providing a means for rapid genetic differentiation of chlamydial strains is described. the technique is based on a single-step sequence-specific separation of pcr-amplified dna fragments by electrophoresis in an agarose gel containing a dna ligand - bisbenzimide-peg. a hypervariable region at the 5' end of the omp2 gene of chlamydiaceae species encoding the 60-kda cysteine-rich outer membrane protein was selected as a target for pcr. the appropriate fragments were amplified f ...200010713423
[chlamydia pneumoniae and arteriosclerosis].introduction: the relationship between chlamydia pneumoniae and atherosclerosis has been assessed in several studies. development and conclusions. their results suggest a possible role of chlamydia pneumoniae in the origin and development of the disease, while the actual link between them are still unknown. however, the presence of chlamydia pneumoniae in patients with atherosclerosis could be just a coincidence.199910714290
