Brief Summary

Atherosclerosis is a civilization disease, which pathophysiology is based on chronic inflammatory response in the wall of vessels that is caused by increase of pro-inflammatory substances. It is a significant challenge for diagnostics and pharmacology. This disease occurs in over 60% of the population over 70 years old. There are many factors that are responsible for this process including group of the arachidonic acid metabolism products - leukotriens, especially leukotriene E4 (LTE4). The effect of these factors was described as the base of pathology not only cardiovascular diseases but also the base of development of asthma and other allergic diseases. The substance which blocks the activity of these factors - montelukast - is a common method of treatment in asthma. The aim of this project is to investigate the influence of cysteinyl leukotriens receptor antagonists on lower limb arteries reocclusion rate in patients with peripheral artery disease (PAD) after endovascular treatment. During previous years we conducted a prospective study, which helped us evaluating the dynamics of leukotriens and thromboxane levels in patients with PAD, who underwent endovascular treatment - peripheral transluminal angioplasty (PTA). We established for the first time the dependence between the increased level of LTE4 in urine (uLTE4) and restenosis or reocclusion occurrence, which translates to the necessity of further procedures and a decrease in the quality of life. We should ask ourselves a question: Is blocking of cysteinyl leukotriens reaction as proinflammatory and proliferative factors, by the use of receptor CysLT1 antagonists going to decrease the quantity of restenosis and reocclusions after endovascular treatment? Within the project performed in the Angiology Department of Jagiellonian University among the patients suffering from PAD and fulfilling all inclusion criteria, the randomized double-blinded clinical study will be performed. Patients will be assigned to two groups: Treatment Group (which will be receiving cysteinyl leukotriene antagonist (montelukast) in a dose of 10mg/day for 12 months) and Control Group to which placebo will be administered. Among all patients population, at every visit at 1., 3., 6., and 12-month clinical state, ultrasound, hemodynamic parameters, and endothelium imaging will be performed as well as uLTE4 measurements. A comparison of the results between both groups will give us an answer if blocking uLTE4 receptors may become a breakthrough in future atherosclerosis treatment. The mechanisms, which lead to restenosis is still not fully understood, and currently used methods of treatment - antiplatelets, anti-proliferative drugs, and anticoagulants - are not fully effective. Thanks to this research the knowledge about treatment and prevention of atherosclerosis will be increased, which will be connected with future better patient care, especially patients with PAD.
