The aim of the study was to evaluate skin microvascular reactivity (MVR) and possible influencing factors (fibrinolysis, oxidative stress, and endothelial function) in patients with Cushing’s syndrome. Twenty-nine patients with active Cushing’s syndrome (ten of them also examined after a successful operation) and 16 control subjects were studied. Skin MVR was measured by laser Doppler flowmetry during post-occlusive (PORH) and thermal hyperemia (TH). Malondialdehyde and Cu,Zn-superoxide dismutase were used as markers of oxidative stress. Fibrinolysis was estimated by tissue plasminogen activator (tPA) and its inhibitor (PAI-1). N-acetyl-β-glucosaminidase, E-selectin, P-selectin, and ICAM-1 were used as markers of endothelial function. Oxidative stress and endothelial dysfunction was present in patients with hypercortisolism, however, increased concentration of ICAM-1 was also found in patients after the operation as compared to controls (290.8±74.2 vs. 210.9±56.3 ng.ml-1, p<0.05). Maximal perfusion was significantly lower in patients with arterial hypertension during PORH and TH (36.3±13.0 vs. 63.3±32.4 PU, p<0.01, and 90.4±36.6 vs. 159.2±95.3 PU, p<0.05, respectively ) and similarly the velocity of perfusion increase during PORH and TH was lower (3.2±1.5 vs. 5.2±3.4 PU.s-1, p<0.05, and 0.95±0.6 vs. 1.8±1.1 PU.s-1, p<0.05, respectively). The most pronounced impairment of microvascular reactivity was present in patients with combination of arterial hypertension and diabetes mellitus., M. Prázný, J. Ježková, E. Horová, V. Lazárová, V.
