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.

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.

Dietary Factors

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.

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.

Paraneoplastic Diseases

Over the past decade, the relationships between various kidney disease and cancer have been established, but not fully elucidated. Development of acute kidney injury or chronic kidney disease as a side effect of cancer treatment is not uncommon. However, renal paraneoplastic diseases are rather unique and less known examples of the association between kidney disease and cancer. These conditions are of importance to the nephrologist as they may be the initial presentation of an underlying malignancy and may not respond to the usual therapies used for their non-paraneoplastic variants. This article will discuss the pathogenesis and challenges in management of paraneoplastic glomerular diseases.

Circular RNAs (circRNAs) are a novel type of non-coding RNAs that have aroused growing attention in this decade. They are widely expressed in eukaryotes and generally have high stability owing to their special closed-loop structure. Many circRNAs are abundant, evolutionarily conserved, and exhibit cell-type-specific and tissue-specific expression patterns. Mounting evidence suggests that circRNAs have regulatory potency for gene expression by acting as microRNA sponges, interacting with proteins, regulating transcription, or directly undergoing translation. Dysregulated expression of circRNAs were found in many pathological conditions and contribute to the pathogenesis and progression of various disorders, including renal diseases. Recent studies have revealed that circRNAs may serve as novel reliable biomarkers for the diagnosis and prognosis prediction of multiple kidney diseases, such as renal cell carcinoma (RCC), acute kidney injury (AKI), diabetic kidney disease (DKD), and other glomerular diseases. Furthermore, circRNAs expressed by intrinsic kidney cells are shown to play a substantial role in kidney injury, mostly reported in DKD and RCC. Herein, we review the biogenesis and biological functions of circRNAs, and summarize their roles as promising biomarkers and therapeutic targets in common kidney diseases.

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.

Kidney Organoids

Kidney dysfunction, including chronic kidney disease and acute kidney injury, is a globally prevalent health problem. However, treatment regimens are still lacking, especially for conditions involving kidney fibrosis. Stem cells hold great promise in the treatment of chronic kidney disease and acute kidney injury, but success has been hampered by insufficient incorporation of the stem cells in the injured kidney. Thus, new approaches for the restoration of kidney function after acute or chronic injury have been explored. Recently, kidney organoids have emerged as a useful tool in the treatment of kidney diseases. In this review, we discuss the mechanisms and approaches of cell therapy in acute kidney injury and chronic kidney disease, including diabetic kidney disease and lupus nephritis. We also summarize the potential applications of kidney organoids in the treatment of kidney diseases. Impact statement Stem cells hold great promise in regenerative medicine. Pluripotent stem cells have been differentiated into kidney organoids to understand human kidney development and to dissect renal disease mechanisms. Meanwhile, recent studies have explored the treatment of kidney diseases using a variety of cells, including mesenchymal stem cells and renal derivatives. This mini-review discusses the diverse mechanisms underlying current renal disease treatment via stem cell therapy. We postulate that clinical applications of stem cell therapy for kidney diseases can be readily achieved in the near future.

Proton pump inhibitors (PPIs) are most widely used medications for acid related gastrointestinal disorders. Accessible evidence based studies suggest that the increased use of PPI is linked to a greater risk of developing kidney diseases. This review aims to determine the association of kidney disease with the use of proton pump inhibitor with various study designs. PubMed, Scopus and Google Scholar databases as well as a reference list of relevant articles were systematically searched for studies by using the following search terms; ‘proton pump inhibitors’, ‘acute kidney injury’, ‘chronic kidney disease’ and ‘end stage renal disease’. Both observational and randomized controlled trials (RCTs) exploring the association of PPI use with kidney disease were eligible for inclusion. A total of 8 articles, including 9 studies (n = 794,349 participants) were identified and included in the review. Majority of the studies showed a higher risk of kidney outcomes in patients taking PPIs, with effect higher of acute kidney injury (4-to 6-fold) compared with chronic kidney disease and end stage renal disease (1.5-to 2.5-fold). However, the studies suggest that the strength of evidence is weak and could not prove causation. The risk increased considerably with the use of high dose of PPIs and prolonged duration of exposure necessitates the monitoring of renal function. Exercising vigilance in PPI use and cessation of proton pump inhibitor when there is no clear indication may be a reasonable approach to reduce the population burden of kidney diseases.

Abstract Background and Aims The creation of vascular access: has it anything to do with a nephrologist ? At first glance, the concept of vascular access is the responsibility of surgical specialists. However, a nephrologist has started executing some of the common intensive treatment methods, using the equipment and techniques, specific to the field of dialysis. In this case, a nephrology specialist sets up different kinds of vascular access, namely the AV (arteriovenous) fistula, the AV graft, and the venous catheter; he/she is, therefore, responsible for its assessment and congruent correction. Method the usage of statistical data, gathered by the medical specialists of the dialysis unit of the Regional Chernihiv Hospital; the analysis of the possible nephrologist’s contribution to the creation of vascular access in patients with kidney diseases. Results During 2017-2019, 332 catheterizations were performed, during each of them vascular access was established: Conclusion 1. A nephrologist, in collaboration with a vascular surgeon, is particularly interested in the creation of vascular access in a patient with chronic kidney disease at the pre-dialysis stage; 2. In most cases, a nephrologist can set up temporary or permanent vascular access in patients with chronic kidney disease or acute kidney injury, which improves the quality of hemodialysis by making him an active participant of the treatment process.
