RAISED IgM AUTOANTIBODY TITER TO LIPOPROTEIDE(A) AS ANTIATHEROGENIC FACTOR IN SEVERE HYPERCHOLESTEROLEMIA PATIENTS
Aim. To investigate on the relation of lipoproteide(a) (Lpa), subfractions of atherogenic lipoproteides and titers of specific autoantibodies (autoAb) with the presence and severity of carotid arteries (CA) lesion in statin-naïve patients with severe hypercholesterolemia. Material and methods. To th...

Zusammenfassung: | Aim. To investigate on the relation of lipoproteide(a) (Lpa), subfractions of atherogenic lipoproteides and titers of specific autoantibodies (autoAb) with the presence and severity of carotid arteries (CA) lesion in statin-naïve patients with severe hypercholesterolemia.
Material and methods. To the study, 133 statin-naïve patients included, age 18 to 75 y.o., with absent clinical signs of coronary heart disease, and with first time diagnosed severe hypercholesterolemia (total cholesterol >7,5 mM/L and/or low density lipoproteides cholesterol >4,9 mM/L) with ultrasound duplex scan data of CA. All patients underwent measurement of Lpa concentration, lipid profile, subfractional content of apoB-100-containing lipoproteides and autoAb titer against them.
Results. According to the data from duplex CA scan, patients were selected to 2 groups: control group (n=76) with no CA atherosclerosis; main group — patients with CA stenosis >20% (n=57). The participants of main group were older than controls, with no other clinical or lipid profile differences. Titre of autoAb IgM specific for Lpa and its oxidized modifications was significantly lower in CA atherosclerosis comparing to controls. The grade of CA stenosis in severe hypercholesterolemia patients positively correlated with age (r=0,24, p=0,005) and negatively — with autoAb IgM to apoB100-containing lipoproteides (r=-0,28 and r=-0,26, p |
