[Genetic markers of the ABO blood system in pulmonary sarcoidosis patients of different ethnic origin]. / Geneticheskie markery krovi sistemy ABO u bol'nykh sarkoidozom legkikh v zavisimosti ot etnicheskoi prinadlezhnosti.

Analysis of published data and investigations of their own permitted the authors to detect the relationship between the incidence of AB0 blood groups and the ethnic appurtenance. The 0(1) and A(II) blood groups were appreciably more incident in the Europeans, including the Russians, whereas in the Asians (Kazakhs et al.) the B(III) group prevailed. In the Russian sarcoidosis patients groups A(II), less frequently B(III) predominated. The clinical course of sarcoidosis is more benign in patients with the 0(I) group, the initial and first stages of the disease predominating. In patients with the A(II) group sarcoidosis runs an unfavorable course, with the second and third stages predominating, and hence, patients with this blood group should be singled out as the risk group.
