IL-10 IS DOWN-REGULATED IN THE CARDIOVASCULAR DISEASES SUSPECTED PATIENTS, INDEPENDENT OF ANGIOGRAPHY.

UNLABELLED: IL-10 and interferon-gamma (IFN-γ) are the important anti and pro-inflammatory cytokines, respectively, which may participate in the cardiovascular disease pathogenesis. Additionally, environmental factors, such as the X-ray, can modulate cytokine expression. Due to the fact that X-ray is used during angiography, hence, angiography may alter expression of the cytokines.

OBJECTIVE

Accordingly, this project was aimed to assess IL-10 and IFN-γ serum levels within cardiovascular patients (with and without vessel stenosis) versus healthy controls and also the effects of angiography on the serum levels of the cytokines.

MATERIAL AND

METHODS

This study was performed on the 80 participants, including twenty cases in each group (healthy controls and cardiovascular patients without vessel stenosis, stenosis of 1 vessel and stenosis of more than 1 vessel) to evaluate IL-10 and IFN-γ serum levels using ELISA technique. The IL-10 and IFN-γ serum levels also compared within group 2, 3 and 4 before and after angiography to explore the effects of the technique on the IL-10 and IFN-γ serum levels.

RESULTS

IL-10, but not IFN-γ, serum levels were higher in the healthy controls than all cardiovascular patients. IL-10 and IFN-γ serum levels were not altered after angiography and also were not differ in the smoker versus non- smoker and opium consuming versus non-opium consuming participants.

CONCLUSION

Due to the results it may be concluded that IL-10 can be considered as a plausible inhibitor of cardio- vascular diseases independent of angiography duration and X-ray, however, IFN-γ has no effects in the Iranian patients suffering from cardiovascular diseases.
