Сывороточный уровень 25-гидроксивитамина D и интерлейкина-1β у женщин с постменопаузальным остеопорозом, инфицированных Helicobacter pylori

Abstract

Dysfunction of the gastrointestinal system in Helicobacter pylori lesions significantly reduces the absorption of not only calcium (Ca), but also vitamin D and other nutrients, the intake of which is critical for bone formation. H. pylory can contribute to the formation of osteoporosis and due to the development of the inflammatory process. The inflammatory process is an important component of the pathogenesis of the above bone disease. Objective: to study of the levels of 25(OH)D and interleukin-1β in blood serum in postmenopausal OP in women with a positive test for antibodies to the Helicobacter pylori CagA antigen. Materials and methods. The study included 250 postmenopausal women, whose indicators (Me [Q1; Q3]) were 62 [56; 68] years, and the duration of the postmenopausal period is 13 [7; 20] years. In all patients, the content of 25(OH)D and interleukin-1β (IL-1β) concentrations were determined in blood serum samples. And total antibodies (IgA, IgM, IgG) to the CagA antigen of the pathogen Helicobacter pylori. Results. In the female group with postmenopausal osteoporosis, the presence of helicobacteriosis is associated with a decrease in the level of 25-hydroxyvitamin D in the blood serum by 14.8% (p=0.045). Serum IL-1β values in postmenopausal women do not depend on H. pylori infection (p>0.05). A negative correlation was found between the values of 25(OH)D and IL-1β in women with osteoporosis and a positive test for total antibodies to H. pylori (rs=-0.25; p<0.05). Conclusion. The results of the study demonstrate that the decrease in vitamin D depends on the infection with Helicobacter pylori in women with postmenopausal osteoporosis (p=0.045). The results of the studies obtained can be used in the diagnostic and treatment-and-prophylactic measures for women in the postmenopausal period.
