Popis: Angiographically visible complex lesions, associated with disrupted plaques and intraluminal thrombus, are more common in unstable angina (UA). The aim of our study was to evaluate the relationship between the complex lesions and the T helper cells related Interleukins (IL). We analyzed the concentrations of IL-10, IL-12, IL-18 using ELISA and that of hsCRP using Latex particle enhanced Immunoturbidimetry in 50 patients of UA. Thirty-one of these patients had complex lesions and 19 had simple lesions as visible during coronary angiography. We further compared them with 30 control subjects having no evidence of coronary artery diseases. The levels of IL-12 in patients having complex lesions tended to be higher than in those having simple lesions and levels of IL-10 tended to be lower in the former than the latter, but the differences were not statistically significant. The patients with complex lesions showed significantly higher concentrations of IL-18 as compared to those having simple lesions. Furthermore, IL-18 was found to be independent predictor for the complex lesion morphology in UA patients. These findings suggest that disrupted plaques and intraluminal thrombus, angiographically visible as complex lesions are associated with increased concentrations of T helper 1 cell related interleukins, mainly IL-18, and IL-18 being a possible bio-marker for risk stratification in UA.
