[Genetic blood markers in occupational bronchial asthma].

When studying patients suffering from occupational bronchial asthma among the inhabitants of Imereti (The Georgian SSR), it was established that the occurrence of blood groups O(1) of ABO and Hp 2-2 system is more frequent among them, compared with that among healthy inhabitants of Imereti. No differences of the frequencies in groups D and d of the Rhesus system were discovered. As a result of sensitizing with a strong allergen (natural silk), the disease starts somewhat faster and the blood groups O(1) and Hp 2-2 occur more frequently than in case of sensitizing with a weak allergen. The study of genetic markers of blood in cases of bronchial asthma in Imereti (The Georgian SSR) revealed the fact that in this ethnic group, being situated so far from Estonia, the shifts characteristic of the distribution of blood groups are similar to those of the patients suffering from bronchial asthma among Estonians.
