Determination of leptin receptor in the serum and relations to laboratory and anthropological parameters in patients with atherosclerotic complications.

Leptin receptors are supposed to have signal effects and are located in most tissues in the organism but we failed to find literary data on concentration (measurement) of leptin receptors in the system circulation. We examined by the method of randomized selection the group of 20 patients with manifested atherosclerosis in whom BMI was calculated. Then we analyzed concentration of leptin receptor (double sandwich ELISA, standard recombinant human leptin), leptin, glucose, insulin, proinsulin, CRP and uric acid in the serum. The control group consisted of 103 probands without signs of atherosclerosis or other manifested diseases. The control group was subjected to determination of BMI, leptin and leptin receptor in the serum. Concentration of leptin receptor does not differ significantly between the patients with atherosclerosis and normal population. Probands with atherosclerosis showed a very close negative correlation between concentration of leptin receptor and leptinemia which is absent in normal population.
