Ethnic differences in apolipoprotein В levels in hyperlipidemia in Russians and the Kirghiz

Abstract

Aim. To evaluate the levels of apolipoprotein В (apo-B) and coronary heart disease (CHD) risk factors in Russians and the Kirghiz with primary hyperlipemia (PHL). Material and methods. Lipid spectrum of the blood (LDLP and HDLP cholesterol, total cholesterol, triglicerides), apo-B, CHD risk factors were studied in 60 Russian and 75 Kirghis patients with PHL aged 28 to 67years (mean age 50.0 + 7.59 years, 56females and 79 males). Results. In Russians a mean level of LDLP cholesterol and apo-B was significantly higher than in Kirghiz patients (3.95 + 1.29 mmol/l vs 3.51+1.17 mmol/l, p = 0.042; 173.3+ 57.3 mg/dl vs 145.5 + 49.3 mg/dl, p = 0.003, respectively). CHD in both ethnic groups occurred with similar rates. The multifactorial regression analysis shows that an apo-B concentration can serve an independent risk factor associated with CHD in the Kirghiz population (p = 0.25, p = 0.03) while in Russians living in Kirghizia this factor is a low content of HDLP cholesterol (p = -0.25, p = 0.05).
