**2. Organ pathologies connected with** *H. pylori* **infection**

*H. pylori* infection, especially in the case of strains producing CagA toxin, promotes development of coronary sclerosis and increases the probability of angina pectoris and cardiac infarct [7]. Effect of CagA toxin on promotion of sclerotic changes in coronary arteries leads to exacerbation of coronary disease, which increases mortality caused by circulatory failure in the group of patients infected with these bacteria and not subjected to eradication [8, 9].

*H. pylori* infection among patients with type 2 diabetes presents more seriously compared to patients without diabetes [10]. Moreover, impact of this infection onto the development of chronic pancreatitis has been reported, which indirectly affects liver function [11].

*H. pylori* infection is associated with many skin conditions. Higher incidence of chronic urticaria, acne rosacea, idiopathic thrombocytopatic purpura, psoriasis, atopic dermatitis, and some other dermatological conditions among patients infected with *H. pylori* has been demonstrated [12].
