[Genetic blood markers in arthritic diseases].

In the course of studying patients affected with arthritic diseases (bronchial asthma, sugar diabetes) a relationship between those diseases and the blood groups of the Hp and MN systems was established. Patients with bronchial asthma more frequently than in the controls belonged to the Hp 2-2 type and to blood groups MN and O (I), whereas the patients affected with sugar diabetes are usually of the Hp 2-1 type and belong to the belong to the blood groups MN and A(II). The investigation of patients affected with other diseases having a pathogenesis similar to that of bronchial asthma or of diabetes and the observation of healthy persons after prophylactic inoculations as well as the study of sugar metabolism in healthy persons all confirm the relationship of Hp, MN and ABO antigens with arthritic diseases.
