Introduction: Interleukin L-17 is produced by Th 17 cells and other cells. There is a debate if IL 17 is atherogenic or atheroprotective. The true role of this interleukin during the development and progression of the coronary artery disease is not known. Objective: To evaluate if there are differences between the IL17 A serum levels according to clinical presentation of the coronary artery disease. Methods: This is a cross sectional study which enrolled 101 patients with acute coronary syndrome (ACS), 100 patients with chronic coronary syndrome (CCS) and 100 healthy volunteers. Blood samples were taken from patients ( at admission) and controls to analysis the level of IL17A. Clinical characteristics were collected through questionnaires. This research was approved by ethical committee. Results: Comparisons of the clinical characteristics between patients with ACS and CCS revealed: mean age ( 62 ± 12.4 vs 63.3 ± 9.8, p = 0.4 ), male (63.4% vs 58%, p = 0.4) hypertension (85.1% vs 79%, p = 0.1) , disyipidemia (48% vs 31%, p =0.01), Diabetes Mellitus (47.5% vs 41%, p = 0.3), previous myocardial infarction (57.4% vs 40%, p = 0,01), smoking (29.7% vs 38%, p = 1). The peripheral concentrations of IL17A according to ACS, CCS and controls were: 5.36 ± 8.83 vs 6.69 ± 17.92 vs 6.26 ± 11.13, p = 0.6. Besides, the comparison between ACS and CCS showed: 5.36 ± 8.83 vs 6.69 ± 17.92, p = 0.3. Conclusion: The main finding os this study was that the circulating IL 17 concentrations were similar in patients with ACS, CCS and healthy volunteers). Besides, there was no difference between patients with ACS and CCS. Therefore, our hypothesis is that in patients with ACS and CCS the circulating IL 17 A concentrations are low or undetectable.

Cad Risk

Abstract Background Hypertriglyceridemia has emerged as a critical coronary artery disease (CAD) risk factor. Rare loss-of-function (LoF) variants in apolipoprotein C-III have been reported to reduce triglycerides (TG) and are cardioprotective in American Indians and Europeans. However, there is a lack of data in other Europeans and non-Europeans. Also, whether genetically increased plasma TG due to ApoC-III is causally associated with increased CAD risk is still unclear and inconsistent. The objectives of this study were to verify the cardioprotective role of earlier reported six LoF variants of APOC3 in South Asians and other multi-ethnic cohorts and to evaluate the causal association of TG raising common variants for increasing CAD risk. Methods We performed gene-centric and Mendelian randomization analyses and evaluated the role of genetic variation encompassing APOC3 for affecting circulating TG and the risk for developing CAD. Results One rare LoF variant (rs138326449) with a 37% reduction in TG was associated with lowered risk for CAD in Europeans (p = 0.007), but we could not confirm this association in Asian Indians (p = 0.641). Our data could not validate the cardioprotective role of other five LoF variants analysed. A common variant rs5128 in the APOC3 was strongly associated with elevated TG levels showing a p-value 2.8 × 10− 424. Measures of plasma ApoC-III in a small subset of Sikhs revealed a 37% increase in ApoC-III concentrations among homozygous mutant carriers than the wild-type carriers of rs5128. A genetically instrumented per 1SD increment of plasma TG level of 15 mg/dL would cause a mild increase (3%) in the risk for CAD (p = 0.042). Conclusions Our results highlight the challenges of inclusion of rare variant information in clinical risk assessment and the generalizability of implementation of ApoC-III inhibition for treating atherosclerotic disease. More studies would be needed to confirm whether genetically raised TG and ApoC-III concentrations would increase CAD risk.
