Background: A high proportion of type 2 diabetes cases are associated with host genetic and environmental factors. During the past decade, microorganisms that inhabit the gut have emerged as contributors to the pathogenesis of obesity and type 2 diabetes. Therefore, manipulation of the human gut microbiota will provide essential clues regarding new therapeutic targets for diabetes. Summary: Several studies have established the presence of gut dysbiosis in patients with type 2 diabetes mellitus, even though there are some differences among the studies that could be explained by differences in ethnicity, diet, and methodology. Gut dysbiosis affects the quality and quantity of short-chain fatty acids and secondary bile acids that act as signaling molecules in energy, glucose, and lipid metabolism. In addition, gut dysbiosis affect intestinal permeability. In particular, a high-fat diet can lead to changes in the gut microbiota that strongly reduce intestinal permeability due to the malfunction of tight junction proteins, such as occludin and ZO-1 [<citeref rid="ref1">1</citeref>]. The formation of leaky gut results in increased plasma levels of lipopolysaccharide, which activate Toll-like receptor 4 and result in innate and adaptive immune responses [<citeref rid="ref2">2</citeref>]. Key messages: Gut dysbiosis play an important role in the pathogenesis of obesity and diabetes, for example, via chronic low-grade inflammation. Normalizing gut dysbiosis could be a new approach to overcome diseases of insulin resistance, such as diabetes mellitus.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) gave rise to the coronavirus disease 2019 (COVID-19) pandemic. A strong correlation has been demonstrated between worse COVID-19 outcomes, aging, and metabolic syndrome (MetS), which is primarily derived from obesity-induced systemic chronic low-grade inflammation with numerous complications, including type 2 diabetes mellitus (T2DM). The majority of COVID-19 deaths occurs in people over the age of 65. Individuals with MetS are inclined to manifest adverse disease consequences and mortality from COVID-19. In this review, we examine the prevalence and molecular mechanisms underlying enhanced risk of COVID-19 in elderly people and individuals with MetS. Subsequently, we discuss current progresses in treating COVID-19, including the development of new COVID-19 vaccines and antivirals, towards goals to elaborate prophylactic and therapeutic treatment options in this vulnerable population.

BACKGROUND: The study of low-grade inflammation in patients with type 2 diabetes mellitus (T2DM) and atherosclerotic cardiovascular diseases is a pressing problem. A deeper understanding of the cascade of inflammatory reactions, possibly mediating the severe atherosclerotic lesions of various vascular pools in patients with diabetes, has the potential to introduce more sophisticated diagnostic and therapeutic approaches into practice. AIM: To study the interrelation of low-grade inflammation and atherosclerosis of peripheral arteries in patients with coronary artery disease (CAD) and T2DM. MATERIALS AND METHODS: The study included 137 patients (77 men and 60 women) with CAD. The average age of patients was 62.0 (57.066.0) years. The first group included 67 patients with CAD and T2DM, and the second group included 70 patients with CAD. Low-grade inflammation was assessed by the levels of high-sensitivity C-reactive protein, interleukin (IL)-1, IL-6, IL-8, IL-10 and TNF-. All patients underwent duplex scanning of carotid arteries and lower extremity arteries (LEAs). RESULTS: Patients with CAD and T2DM showed significantly greater values of stenosis of carotid arteries and LEAs. Direct correlation was revealed between markers of inflammation and the degree of stenosis of the femoral and tibial arteries, as well as the intima-media thickness of the carotid and femoral arteries. In the group of patients with T2DM, the value of IL-1 was 2.04 (0.982.52) pg/mL, which was significantly less than 2.43 (1.843.19) pg/mL for patients in the second group (p = 0.010). The values of IL-6 were also significantly lower in the first group of patients, at 1.84 (0.734.41) pg/mL vs. 3.73 (2.2710.2) pg/mL in the first and second groups, respectively (p = 0.008). The dose of metformin was inversely correlated with the level of IL-6 (r = 0.314, p = 0.003). CONCLUSIONS: Patients with CAD and T2DM compared with patients without diabetes had significantly greater values of stenosis of peripheral arteries. The levels of IL-1 and IL-6 in the group of patients with CAD and T2DM were significantly lower in comparison with patients without diabetes. The dose of metformin was inversely correlated with the level of IL-6.

AbstractA strong and expanding evidence base supports the influence of gut microbiota in human metabolism. Altered glucose homeostasis is associated with altered gut microbiota, and is clearly associated with the development of type 2 diabetes mellitus (T2DM) and associated complications. Understanding the causal association between gut microbiota and metabolic risk has the potential role of identifying susceptible individuals to allow early targeted intervention.
