Special Issue "Comorbidities in Chronic Kidney Disease (CKD)"
Deadline for manuscript submissions: 31 March 2020.
Interests: chronic renal failure, hypertension, proteomics, mediator identification, mediator identification, mass-spectrometry, chromatography, pathophysiology of kidney diseases
Cardiovascular disease causes 47% of all deaths in Europe, 10% of Europeans suffer from chronic kidney disease, and 5–8% of elderly aged 60 years or older have to live with cognitive impairment. This disease trio is associated with end-organ damage in the kidney, heart, vasculature, and brain and displays as highly frequent comorbidities. Specifically, ~45% of patients with chronic kidney disease stage 4–5 die from cardiovascular disease, and chronic kidney disease and cardiovascular disease raise the risk of cognitive impairment 2–2.5-fold. Of note, risks of cardiovascular disease and cognitive impairment increase with chronic kidney disease severity but are already significantly higher in early chronic kidney disease compared to non-chronic kidney disease.
Chronic kidney disease, cardiovascular disease, and cognitive impairment are most likely triggered by common pathological molecular mechanisms, with chronic kidney disease further amplifying pathological triggers for co-developing cardiovascular disease and cognitive impairment, which is already present at an early stage (chronic kidney disease stage 1–3). This Special Issue will focus on both causative molecular and cellular mechanisms for diagnosis and prognosis of cardiovascular disease and cognitive impairment in chronic kidney disease, as well as biomarkers for diagnosis, prognosis, and monitoring of comorbid patients.

Chronodisruption: A Poorly Recognized Comorbidity in CKD
Alberto Ortiz et al.
Abstract: Circadian rhythms are required for normal physiology of diverse organs, including the kidneys. Chronodisruption refers to the disruption of circadian rhythms. White there is evidence that circadian rhythms may be altered in kidney disease and that altered circadian rhythms may accelerate CKD progression, there is no comprehensive review of the impact of chronodisruption on CKD and its manifestations. We now discuss evidence for chronodisruption in CKD, the impact of chronodisruption on CKD manifestations, its therapeutic implications and current answered questions.

Abstract: Cardiovascular (CV) disease is highly prevalent in the population with chronic kidney disease (CKD), where the risk of CV death in early-stages far exceeds the risk of progression to dialysis. The presence of chronic kidney disease-mineral and bone disorder (CKD-MBD) has shown a strong correlation with CV events and mortality. As non-atheromatous processes could point out why standard CV disease–modifying drugs do not provide such an impact on CV mortality in CKD as seen in general population, we summarize here the potential association of those comorbidities with the older (parathyroid hormone, phosphate) and newer (FGF-23, Klotho, sclerostin) CKD-MBD biomarkers.
Molecular and Cellular Mechanisms that Underly Indoxyl Sulfate and p-Cresyl Sulfate Induced Arterial Calcification

Abstract: The protein-bound uremic toxins, indoxyl sulfate and p-cresyl sulfate, are considered as harmful vascular toxins. Arterial media calcification, or the deposition of calcium-phosphate crystals in the arteries, contributes significantly to the cardiovascular mortality in elderly and patients with chronic kidney disease (CKD) and diabetes. Recently, we reported that both indoxyl sulfate and p-cresyl sulfate trigger moderate to severe calcification in the aorta and peripheral vessels of CKD rats. This review describes the molecular and cellular mechanisms by which these uremic toxins induce arterial media calcification. A complex interplay between inflammation-, coagulation- and lipid metabolism pathways as well as epigenetic factors is crucial in indoxyl sulfate/p-cresyl sulfate-induced arterial media calcification. High levels of glucose are linked to these events, suggesting that a good balance between glucose and lipid levels might be important. On the cellular level, effects on endothelial cells, which act as the primary sensors of circulating pathological triggers, might be as important as those on vascular smooth muscle cells. Endothelial dysfunction, provoked by indoxyl - and p-cresyl sulfate triggered oxidative stress, may be considered a key event in the onset and development of arterial media calcification. In this review a series of outstanding questions such as the role of miRNA’s, phenotypic switching of both endothelial and smooth muscle cells and new types of (programmed) cell death in arterial media calcification related to protein-bound uremic toxins are put forward and discussed.
Pathogenesis of Impaired Fertility in Patients with CKD

Abstract: Impaired fertility is one of the most important comorbidities in women with chronic kidney disease (CKD). It may be caused by several factors – among others: reduced renal clearance of different hormones (e.g. prolactin, leptin), disturbed activity if the pituitary-gonadal axis, impairment of ovarian function and reduced ovarian reserve, accumulation of uremic toxins, sexual function disorders, and depression. Prevalence of impaired fertility is increasing with the degree of kidney function deterioration and is present in more than 90% women with end stage kidney disease (ESKD), therefore pregnancy is ca. 40-times less frequent in women treated with chronic hemodialysis than in age-matched general population. Successful kidney transplantation in women with ESKD reduces accumulation of uremic toxins, restores function of the endocrine system and improves fertility.
