Chronic kidney disease (CKD) is generally progressive and irreversible, structural or functional renal impairment for 3 or more months affecting multiple metabolic pathways. Recently, the composition, dynamics, and stability of a patient’s microbiota has been noted to play a significant role during disease onset or progression. Increasing urea concentration during CKD can lead to an acceleration of the process of kidney injury leading to alterations in the intestinal microbiota that can increase the production of gut-derived toxins and alter the intestinal epithelial barrier. A detailed analysis of the relationship between the role of intestinal microbiota and the development of inflammation within the symbiotic and dysbiotic intestinal microbiota showed significant changes in kidney dysfunction. Several recent studies have determined that dietary factors can significantly influence the activation of immune cells and their mediators. Moreover, dietary changes can profoundly affect the balance of gut microbiota. The aim of this review is to present the importance and factors influencing the differentiation of the human microbiota in the progression of kidney diseases, such as CKD, IgA nephropathy, idiopatic nephropathy, and diabetic kidney disease, with particular emphasis on the role of the immune system. Moreover, the effects of nutrients, bioactive compounds on the immune system in development of chronic kidney disease were reviewed.

Although dyslipidemia is associated with chronic kidney disease (CKD), it is more common in nephrotic syndrome (NS), and guidelines for the management of hyperlipidemia in NS are largely opinion-based. In addition to the role of circulating lipids, an increasing number of studies suggest that intrarenal lipids contribute to the progression of glomerular diseases, indicating that proteinuric kidney diseases may be a form of “fatty kidney disease” and that reducing intracellular lipids could represent a new therapeutic approach to slow the progression of CKD. In this review, we summarize recent progress made in the utilization of lipid-modifying agents to lower renal parenchymal lipid accumulation and to prevent or reduce kidney injury. The agents mentioned in this review are categorized according to their specific targets, but they may also regulate other lipid-relevant pathways.

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 review of the literature 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 influence of colon dysbiosis 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.

The Relationship

Nutrition is crucial for the management of patients affected by chronic kidney disease to slow down disease progression and to correct symptoms. The mainstay of nutritional approach to renal patients is protein restriction coupled with adequate energy supply to prevent malnutrition. However, other aspects of renal diets, including fiber content, can be beneficial. This paper summarizes the latest literature on the relationship between the type of dietary fiber and prevention and management of CKD, with special attention to intestinal microbiota and the potential protective role of renal diets. A proper amount of fiber should be recommended not only in general population but also in chronic kidney disease patients, to asses an adequate composition and metabolism of intestinal microbiota and to reduce the risks connected with obesity, diabetes and dyslipidemia.

Recent studies have revealed that the gut microbiota plays a crucial role in maintaining a healthy, as well as diseased condition. Various organs and systems, including the kidney, are affected by the gut microbiota. While the impacts of the gut microbiota have been reported mainly on chronic kidney disease, acute kidney injury (AKI) is also affected by the intestinal environment. In this review, we discussed the pathogenesis of AKI, highlighting the relation to the gut microbiota. Since there is no established treatment for AKI, new treatments for AKI are highly desired. Some kinds of gut bacteria and their metabolites reportedly have protective effects against AKI. Current studies provide new insights into the role of the gut microbiota in the pathogenesis of AKI.

Acute and chronic kidney injuries result from structural dysfunction and metabolic disorders of the kidney in various etiologies, which significantly affect human survival and social wealth. Nephropathies are often accompanied by various forms of cell death and complex microenvironments. In recent decades, the study of kidney diseases and the traditional forms of cell death have improved. Nontraditional forms of cell death, represented by ferroptosis and necroptosis, have been discovered in the field of kidney diseases, which have reshuffled the role of traditional cell death in nephropathies. Although interactions between ferroptosis and acute kidney injury (AKI) have been continuously explored, studies on ferroptosis and chronic kidney disease (CKD) remain limited. Here, we have reviewed the therapeutic significance of ferroptosis in AKI and anticipated the curative potential of ferroptosis for CKD in the hope of providing insights into ferroptosis and CKD.

Abstract Inherited kidney diseases (IKDs) are among the leading causes of early-onset chronic kidney disease (CKD) and are responsible for at least 10–15% of cases of kidney replacement therapy (KRT) in adults. Pediatric nephrologists are very aware of the high prevalence of IKDs among their patients, but this is not the case for adult nephrologists. Recent publications have demonstrated that monogenic diseases account for a significant percentage of adult cases of CKD. A substantial number of these patients have received a non-specific/incorrect diagnosis or a diagnosis of CKD of unknown etiology, which precludes correct treatment, follow-up and genetic counseling. There are a number of reasons why genetic kidney diseases are difficult to diagnose in adulthood: a) adult nephrologists, in general, are not knowledgeable about IKDs, b) existence of atypical phenotypes, c) genetic testing is not universally available, d) family history is not always available or may be negative, e) lack of knowledge of various genotype–phenotype relationships, f) conflicting interpretation of the pathogenicity of many sequence variants.

The human gut microbiota is a complex cluster composed of 100 trillion microorganisms, which holds a symbiotic relationship with the host under normal circumstances. Intestinal flora can facilitate the treatment of human metabolic dysfunctions and interact with the intestinal tract, which could influence intestinal tolerance, immunity, and sensitivity to inflammation. In recent years, significant interests have evolved on the association of intestinal microbiota and kidney diseases within the academic circle. Abnormal changes in intestinal microbiota, known as dysbiosis, can affect the integrity of the intestinal barrier, resulting in the bacterial translocation, production, and accumulation of dysbiotic gut-derived metabolites, such as urea, indoxyl sulfate (IS), and p-cresyl sulfate (PCS). These processes lead to the abnormal activation of immune cells; overproduction of antibodies, immune complexes, and inflammatory factors; and inflammatory cell infiltration that can directly or indirectly cause damage to the renal parenchyma. The aim of this review is to summarize the role of intestinal flora in the development and progression of several renal diseases, such as lupus nephritis, chronic kidney disease, diabetic nephropathy, and renal ischemia-reperfusion injury. Further research on these mechanisms should provide insights into the therapeutic potential of regulating intestinal flora and intervening related molecular targets for the abovementioned nephropathy.

OBJECTIVES: This study aims to present the confirmed cases of SARS-CoV-2 infection in pediatric patients with chronic and acute kidney diseases admitted to a tertiary pediatric hospital. METHODS: Descriptive and retrospective observational study with all children hospitalized between March and June 2020 who had, simultaneously, SARS-CoV-2 infection and renal pathologies. Of this total of patients, those who had another underlying disease besides the renal disease were excluded. RESULTS: During the period, nine children with kidney disease were admitted to the hospital and had infection confirmed by the new coronavirus through positive RT-PCR. Regarding the underlying disease, seven had only kidney disease, three of whom had stage 5 chronic kidney disease; one, with stage 1 chronic kidney disease; one, with cortic-sensitive nephrotic syndrome; and two, with acute kidney injury. Two patients in this study had already undergone kidney transplantation, used immunosuppressants and had their doses reduced due to the infectious condition. Only one required oxygen therapy and transfer to the intensive care unit, but was not intubated and returned to the ward within 24 hours. CONCLUSIONS: According to the cases described, the pediatric population with kidney disease, including those using immunosuppressants due to acute transplant rejection, seems to evolve without severe COVID-19, therefore there is no great divergence in relation to the population of the same healthy age group.
