The Association of Chlamydia pneumonia and Helicobacter pylori IgG Seropositivity With Omentin-1, Visfatin and Adiponectin Levels in Postmenopausal Women.

Abstract- Some adipocytokines are cardioprotective or pro-inflammatory for thecardiovascular system. Chronic infection with Chlamydia pneumonia (C. pneumoniae) and Helicobacter pylori (H. pylori) has been also considered as novel risk factors for atherosclerosis. The main aim of the current population-based study is to investigate the potential link between circulating adipocytokines and Chlamydia pneumonia or H. pylori IgG seropositivity. A total of 250 healthy postmenopausal women who participated in a prospective cohort study were evaluated for IgG antibodies directed against C. pneumoniae and H. pylori. Omentin-1, visfatin, adiponectin, and high-sensitivity C-reactive protein were measured by highly specific enzyme-linked immunosorbent assay methods. The prevalence of IgG antibodies against C. pneumoniae and H. pylori among the studied population was 20.4% (51 women) and 57.2% (143 women), respectively. There were no significant differences in adipocytokine levels between H. pylori IgG seropositive and H. pylori seronegative subjects. Similar results for visfatin and omentin-1 were found when C. pneumoniae IgG seropositive were compared with C. pneumoniae IgG seronegative subjects. However, in general, linear model adjusted for age; body mass index and hs-CRP levels revealed asignificant difference between C. pneumoniae seropositive and C. pneumoniae seronegative subjects for circulating adiponectin. In conclusion, C. pneumonia IgG seropositivity was associated with higher adiponectin levels in postmenopausal women. The elucidation of interaction mechanism of C. pneumonia and a cardioprotective adipocytokine (adiponectin) will be useful in future therapeutic strategies. © 2016 Tehran University of Medical Sciences.
