The paper is concerned with materials characterizing physicochemical properties of haemosorbents of varying grades. Adsorption of different uraemic toxins was studied. The possibility of microembolization of internal organs and tissues with haemosorbent particles was explored in the course of prolonged treatment with the use of haemosorption. Different approaches to connecting the sorption column to the dialyzer were examined to disclose an optimal variant. The authors report the results of applying haemosorption in patients who had received haemodialysis therapy to prevent complications. The blood response to the prolonged haemosorption treatment was analyzed. It is recommended that long-term (6-7 hours) sessions of haemosorption might be performed using carbons having high sorption capacity.
Interest in studying the role of the gastrointestinal tract in maintaining homeostasis in chronic kidney disease is a traditional one. It served, in particular, as a starting point for the creation of enterosorbents. However, if earlier the main attention was paid to the mechanical removal of a number of potentially dangerous biologically active substances, recently an intestinal microbiota has become an object of interest. The first part of the literature review on this topic is devoted to questions of terminology, the normal physiology of the colon microbiota. A detailed description of dysbiosis is given. The features of the main groups of microorganisms are reflected. The hypothetical and confirmed interrelations of the intestine-kidney axis are presented. The pathogenetic mechanisms of the colon dysbiosis influence on the processes of local and systemic inflammation are discussed. The influence of dysbiosis on the state of the kidney parenchyma and its participation in the progression of CKD are debated.

Disturbance of the thyroid function is often detected in patients with different profiles. A special feature of patients with chronic kidney disease is the higher incidence of various thyroid function disturbances, especially hypothyroidism. It is known that in patients with chronic kidney disease (CKD) iodine excretion from the body is violated, since normally 90% of iodine is excreted in urine. Accumulation of high concentrations of inorganic iodine leads to the formation of the Wolf-Chaikoff effect: suppression of iodine organization in the thyroid gland and disruption of the thyroid hormones synthesis. Peripheral metabolism of thyroid hormones is also disturbed, namely, deiodinase type I activity is suppressed and peripheral conversion of T4 into T3 is inhibited (so-called low T3 syndrome). Therefore, patients with CKD are often diagnosed with hypothyroidism, and the origin of hypothyroidism is not always associated with the outcome of autoimmune thyroiditis. The article presents an overview of a large number of population studies of thyroid gland dysfunction in patients with CKD, as well as experimental data specifying the pathogenetic mechanisms of thyroid dysfunction in patients with CKD. Therapeutic tactics are still not regulated. However, in a number of studies, replacement therapy with thyroid hormones in patients with CKD had some advantages.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
