Introduction: The metabolic syndrom (MS) is characterized by a whole of metabolic abnormalities and hemodynamics, being associated with the higher risk from mellitus diabetes type 2 (DM2) and cardiovasculares events. Inflammatory Citokines, as interleucine 6 (IL6) and Necrosis Tumoral Factor- Alpha (NTF-α) that contribute to the resistence of insuline, afect the vascular function, by causing atherosclerosis disease. Besides, many studies have been associated to the presence of infectious agents as Chlamydia pneumoniae with iniciation and or progression of the atherosclerosis. Objective: Evaluate the seric levels of the citokines pro-inflammatories (NTFalpha and IL-6) and the anti-Chlamydia pneumoniae antibodies in patients with MS with or without cardiovascular events. Material and methods: Transversal study constituted by 147 citzens from the risk cardiometabolic policlinic from Cardiology Service at São Lucas Hospital At Pontifícia Universidade Católica from Rio grande do Sul, which 100 (68%) with MS without cardiovascular events and 47(32%) with MS events, being 13 (6,11%) with IMI and 10 (4,7%) BVA. The MS diagnosis was determined by the NCEP-ATPIII criteria. Interleucine-6, NTF-α and anti-Chlamydia pneumoniae antibodies IgG and IgA were determined by imunoenzymatic analysis (Elisa), C Protein reactive ultra sensitive (PCR-us) that was mensurated by nefelometry; HDL cholesterol and triglycerides by the enzimatic colorimetric method. Results: From the total of participants, 108 (72,8%) were from the female sex and 39 (26,5%) were from male sex. The average age of the citzens with events was 61,26 ± 8,5 and 59,32 ± 9,9 to citzens with no events. (p=0,279). The MS group and without event presented higher weight, height, CMI and abdominal circumference compared to the group with MS with event. Hipertension, dislipidemy, glycose intolerance and tabagysm predominated in the group with cardiac events, without statistic differences. IL-6, NTF-α and periferic vascular disease presented higher levels into citzens with events (p=0,001). It was observed more elevated levels of IgG antibodies for Chlamydia pneumoniae into the group with no events, while the IgA was higher into the group with events when compared between the two groups. In seric levels to RCP-us were similar between the groups but not presenting significant statistics differences. In relation to IMI and the BVA, these citzens presented iflammatory levels signifcantly higher (p=0,001), when compared to the controls. The intense marker fase (PCR-us) did not presented significative difference, as well as the Chlamydia presence IgG and IgA. The positive association was observed with oral hypoglyceminant statins, injectable and anti-inflammatory not steroid in the group with events. Conclusion: There is the association between IL6 and NTF-alpha with metabolic syndrom in patients with cardiovascular events, compared to the ones without events. The PCR-us did not demonstrade to be na independent risk factor for these events. When we evaluate patients with Ms, with AMI and BVA, we verified that the antibodies levelsIgG and IgA anti-Chlamydia pneumoniae were not statistically significant when compared to the group without cardiovascular events.
