Biomarkers, the measurable indicators of biological conditions, are fast becoming a popular approach in providing information to track disease processes that could lead to novel therapeutic interventions for chronic conditions. Inherited, chronic kidney disease affects millions of people worldwide and although pharmacological treatments exist for some conditions, there are still patients whose only option is kidney dialysis and kidney transplantation. In the past 10 years, certain chronic kidney diseases have been reclassified as ciliopathies. Cilia in the kidney are antenna-like, sensory organelles that are required for signal transduction. One of the signalling pathways that requires the primary cilium in the kidney is Wnt signalling and it has three components such as canonical Wnt, non-canonical Wnt/planar cell olarity (PCP) and non-canonical Wnt/Ca2+ signalling. Identification of the novel role of ATM INteractor (ATMIN) as an effector molecule in the non-canonical Wnt/PCP pathway has intrigued us to investigate its potential role in chronic kidney disease. ATMIN could thus be an important biomarker in disease prognosis and treatment that might lighten the burden of chronic kidney disease and also affect on its progression.

Disease Manifestation

Chronic kidney disease (CKD) encompasses a group of diverse diseases that are associated with accumulating kidney damage and a decline in glomerular filtration rate (GFR). These conditions can be of an acquired or genetic nature and, in many cases, interactions between genetics and the environment also play a role in disease manifestation and severity. In this review, we focus on genetically inherited chronic kidney diseases and dissect the links between canonical and non-canonical Wnt signalling, and this umbrella of conditions that result in kidney damage. Most of the current evidence on the role of Wnt signalling in CKD is gathered from studies in polycystic kidney disease (PKD) and nephronophthisis (NPHP) and reveals the involvement of β-catenin. Nevertheless, recent findings have also linked planar cell polarity (PCP) signalling to CKD, with further studies being required to fully understand the links and molecular mechanisms.

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.

Conventional Risk Factors

Cardiovascular disease (CVD) is prevalent among patients with chronic kidney disease (CKD) and its occurrence and severity cannot be fully defined by the conventional cardiovascular risk factors namely age, hypertension, dyslipidaemia, diabetes mellitus and obesity. Contemporary studies have examined the role of non-conventional risk factors such as anemia, hyperhomocysteinemia, calcium and phosphate metabolism, vascular stiffness due to endothelial dysfunction ( ED), oxidative injury, and inflammation in the causation of CVD in CKD. Therapeutic interventions used in non-CKD patients are found to be less effective on patients with CKD. The purpose of this review was to gather available evidence on the CVD risk among CKD patients. Numerous mechanisms have been postulated to describe the increased atherogenicity in CKD patients. We discuss these mechanisms especially arterial stiffness, ED and inflammation in detail. In conclusion, CVD in CKD is still an unexplored area which needs further studies to uncover the possible mechanisms. Identifying newer therapies to improve health among this group of patients is of paramount importance.

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.

Abstract Background and objectives: This review focuses on three areas, basic acid-base physiology especially concerning hydrogen ion balance, development of acidosis in chronic kidney disease (CKD), and the consequences of acidosis. We highlight what is well established, what is less certain, and what is unknown. Method and results: The literature on acidosis in CKD were searched from 2004 to 2010 utilizing PubMed, Google Scholar, and Ovid to augment the classic work on acid base physiology over the past three decades. The original research in endogenous acid production and net acid excretion were reviewed. Touching upon the development of metabolic acidosis in CKD, we focused on the consequences of chronic metabolic acidosis on growth and other important variables. Finally, we recognize the significant issue of patients’ medical non-compliance and presented treatment strategy to counter this problem. Conclusion: The correction of acidosis in chronic kidney disease needs no advocacy. The case is made conclusively. Patient non-compliance because of the medication that needs to be taken several times a day is a problem, requiring due diligence.

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.

Additional Role

The role of various factors contributing to the development of systemic persistent low-grade inflammation in chronic kidney disease (CKD) is considered. It is reported that inflammation in patients with CKD is directly correlated with the glomerular filtration rate (GFR) and culminates in the terminal stage of renal failure, where extracorporeal factors such as dialysate contaminants, dialysate microbiological quality and the biocompatibility of factors in the dialysis chain play an additional role. The effectiveness of therapeutic interventions aimed at correcting inflammation in patients with CKD is discussed. Further investigations are needed to evaluate the effects of these interventions on hard outcomes, as well as to better understand the role of inflammation in selected CKD populations, particularly in children.

Dehydration, a condition that characterizes excessive loss of body water, is well known to be associated with acute renal dysfunction; however, it has largely been considered reversible and to be associated with no long-term effects on the kidney. Recently, an epidemic of chronic kidney disease has emerged in Central America in which the major risk factor seems to be recurrent heat-associated dehydration. This has led to studies investigating whether recurrent dehydration may lead to permanent kidney damage. Three major potential mechanisms have been identified, including the effects of vasopressin on the kidney, the activation of the aldose reductase-fructokinase pathway, and the effects of chronic hyperuricemia. The discovery of these pathways has also led to the recognition that mild dehydration may be a risk factor in progression of all types of chronic kidney diseases. Furthermore, there is some evidence that increasing hydration, particularly with water, may actually prevent CKD. Thus, a whole new area of investigation is developing that focuses on the role of water and osmolarity and their influence on kidney function and health.

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.
