Gut microbiota in patients with arterial hypertension and metabolic syndrome

Abstract

In recent years, attention has been growing to assessing the role of the state of intestinal microbiocenosis in the development of cardiovascular diseases, including arterial hypertension (AH) and metabolic syndrome (MS), the individual components of which are more or less associated with the state of the microbiota. In this regard, we made an attempt to clarify the features of the intestinal microbiota in hypertensive patients with MS in a comparative aspect with those with isolated hypertension. A microbiological study of feces was carried out in 86 patients, of which 46 with AH (comparison group) and 40 with AH and MS (main group). The microbiota of patients’ faeces was investigated using the classical bacteriological method and the biochemical method for express diagnostics of dysbiosis. For fecal microbiota in AH with MS, in comparison with AH, a lower release of representatives of normal microfl ora (bacteroids, latobacilli, bifi dobacteria), with the exception of Escherichia coli, is characteristic, more frequent excretion of facultative microfl ora (enterococci, Klebsiella, peptostreptococcus, staphylococcus protrusion)., II and III degree of dysbiosis (versus I and II with hypertension). The study revealed that the composition of the intestinal microbiota in patients with hypertension is associated with MS both in terms of a decrease in individual representatives of normal microfl ora and in terms of the greater presence and appearance of new representatives of opportunistic microfl ora, forming a high degree of dysbiosis in hypertensive patients with MS.
