Background: Cardiorenal syndrome (CRS) in patients with end-stage kidney disease (ESKD) represents mainly cardiovascular disease (CVD) due to various complications associated with renal dysfunction—defined as type 4 CRS by Ronco et al.—because the effect of cardiac dysfunction on the kidneys does not need to be taken into consideration, unlike in non-dialysis dependent chronic kidney disease (CKD). Summary: Patients with ESKD are often in a state of chronic inflammation due to the upregulation of proinflammatory cytokines. Chronic inflammation leads to malnutrition and consequently to vascular endothelial dysfunction and vascular calcification, which is referred to as malnutrition-inflammation-atherosclerosis (MIA) syndrome and acts as a major risk factor for CVD. Anemia also plays a crucial role in CVD, and individuals with erythropoietin-resistant anemia have a particularly high risk of CVD. However, caution is emphasized because not only anemia itself, but also the overtreatment of anemia with erythropoiesis-stimulating agents aimed at elevating hemoglobin to ≥13 g/dl can also increase the risk of CVD. In CKD-mineral and bone disorder (CKD-MBD), phosphate load triggers the interactions between various factors such as calcium, parathyroid hormone, vitamin D, and fibroblast growth factor 23, promoting vascular calcification and thus becoming a risk factor for CVD. Key Messages: In addition to traditional atherosclerosis risk factors such as hypertension, diabetes, and dyslipidemia, the involvement of MIA syndrome, anemia, and CKD-MBD accompanying CKD have also become a focus for investigation as major players in CRS in patients with ESKD.

Abstract Background Sex differences are underappreciated in the current understanding of cardiovascular disease (CVD) in association with chronic kidney disease (CKD). A hallmark of CKD is vascular aging that is characterised, amongst others, by; systemic inflammation, microbiota disbalance, oxidative stress, and vascular calcification—features linked to atherosclerosis/arteriosclerosis development. Thus, it is the necessary to introduce novel biomarkers related to athero-/arteriosclerotic damage for better assessment of vascular ageing in patients CKD. However, little is known about the relationship between uraemia and novel CVD biomarkers, such as growth differentiation factor-15 (GDF-15), cartilage glycoprotein-39 (YKL-40) and matrix metalloproteinase-9 (MMP-9). Therefore, we hypothesise that there are sex-specific relationships between GDF-15, YKL-40, MMP-9 levels in end-stage kidney disease (ESKD) patients in relation to gut microbiota, vascular calcification, inflammation, comorbidities, and all-cause mortality. Methods ESKD patients, males (n = 151) and females (n = 79), not receiving renal replacement therapy were selected from two ongoing prospective ESKD cohorts. GDF-15, YKL-40 and MMP9 were analysed using enzyme-linked immunosorbent assay kits. Biomarker levels were analysed in the context of gut microbiota-derived trimethylamine N-oxide (TMAO), vascular calcification, inflammatory response, oxidative stress, comorbidities, and all-cause mortality. Results Increased GDF-15 correlated with higher TMAO in females only, and with higher coronary artery calcification and IL-6. In females, diabetes was associated with elevated GDF-15 and MMP-9, whilst males with diabetes only had elevated GDF-15. No associations were found between biomarkers and CVD comorbidity. Deceased males and females had higher GDF-15 concentrations (p = 0.01 and p < 0.001, respectively), meanwhile only YKL-40 was increased in deceased males (p = 0.02). Conclusions In conclusion, in males GDF-15 and YKL-40 were related to vascular calcification, inflammation, and oxidative stress, whilst in females GDF-15 was related to TMAO. Increased levels of YKL-40 and GDF-15 in males, and only GDF-15 in females, were associated with all-cause mortality. Our findings suggest that sex-specific associations of novel CVD biomarkers have a potential to affect development of cardiovascular complications in patients with ESKD.

Abstract Chronic kidney disease (CKD), especially end-stage kidney disease (ESKD), is associated with increased risk for cardiovascular events and all-cause mortality. Exercise intolerance as well as reduced cardiovascular reserve are extremely common in patients with CKD. Cardiopulmonary exercise testing (CPET) is a non-invasive, dynamic technique that provides an integrative evaluation of cardiovascular, pulmonary, neuropsychological and metabolic function during maximal or submaximal exercise, allowing the evaluation of functional reserves of these systems. This assessment is based on the principle that system failure typically occurs when the system is under stress and, thus, CPET is currently considered to be the gold-standard for identifying exercise limitation and differentiating its causes. It has been widely used in several medical fields for risk stratification, clinical evaluation and other applications but its use in everyday practice for CKD patients is scarce. This article describes the basic principles and methodology of CPET and provides an overview of important studies that utilized CPET in patients with ESKD, in an effort to increase awareness of CPET capabilities among practicing nephrologists.
