Aim. To investigate the prevalence, structure, and features of the course of chronic kidney disease (CKD) in patients with coronary heart disease (CHD) associated with comorbid diseases. Methods. The observation group consisted of 257 patients of the Interregional Clinical Diagnostic Center (Kazan) with coronary heart disease (20142018): 183 males and 74 females, aged from 38 to 95 years (mean age 61.80.6). Observation program: clinical examination; serum creatinine and lipid profiles, the albumin/creatinine ratio in a single portion of urine, morning urine osmolality, glomerular filtration rate estimated by the CKD-EPI; renal scintigraphy, ultrasonography of the kidneys, renal Doppler ultrasound and angiography. Chronic kidney disease was diagnosed if one of the criteria was met: the glomerular filtration rate 60 ml/min/1.73 m2 or the ratio of albumin to creatinine in urine (ACR) 30 mg/g. Statistical analysis was performed by using the methods of variational statistics: determination of the arithmetic mean (M), standard error of the mean (m) and difference significance according to the Student's test (t). Results. Examination of patients revealed the following comorbid diseases and syndromes: hypertension (90.7%), hyper- and dyslipidemia (96.5%), overweight/obesity (74.3%), diabetes mellitus (17.9%), chronic heart failure stages IIIa according to StrazheskoVasilenko classification (100%). 164 (63.8%) patients were first time diagnosed with chronic kidney disease: hypertensive nephropathy in 66.4%, ischemic renal disease in 21.9%, diabetic nephropathy in 2.4%, a combination of diabetic and hypertensive nephropathy in 9.3%. 51.2% of patients had stage 2 of chronic kidney disease, 42.1% stage 3, 6.7% stage 4 or 5. A feature of chronic kidney disease is its latent course (absence of complaints and clinical manifestations) and, as a consequence, unidentified diagnosis at the prehospital stage, which is generally characteristic of secondary nephropathies in cardiovascular diseases and these comorbid conditions. Conclusion. Chronic kidney disease was first diagnosed in 63.8% of patients with coronary heart disease with 1 to 5 comorbid diseases; a feature of chronic kidney disease is its secondary nature, the course of the disease is hidden by underlying and/or comorbid disease and, as a result, its late diagnosis.

Serum soluble Fas (sFas) levels are associated with erythropoietin (Epo) hyporesponsiveness in patients with chronic kidney disease (CKD). Whether sFas could predict the need for erythropoiesis-stimulating agent (ESA) usage and its influence in erythropoiesis remain unclear. We evaluated the relation between sFas and ESA therapy in patients with CKD with anemia and its effect on erythropoiesis in vitro. First, we performed a retrospective cohort study with 77 anemic patients with nondialysis CKD. We performed in vitro experiments to investigate whether sFas could interfere with the behavior of hematopoietic stem cells (HSCs). HSCs were isolated from umbilical cord blood and incubated with recombinant sFas protein in a dose-dependent manner. Serum sFas positively correlated with Epo levels ( r = 0.30, P = 0.001) but negatively with hemoglobin ( r = −0.55, P < 0.001) and glomerular filtration rate ( r = −0.58, P < 0.001) in patients with CKD at baseline. Elevated sFas serum levels (4,316 ± 897 vs. 2,776 ± 749, P < 0.001) with lower estimated glomerular filtration rate (26.2 ± 10.1 vs. 33.5 ± 14.3, P = 0.01) and reduced hemoglobin concentration (11.1 ± 0.9 vs. 12.5 ± 1.2, P < 0.001) were identified in patients who required ESA therapy compared with patients with non-ESA. Afterward, we detected that the sFas level was slight correlated with a necessity of ESA therapy in patients with nondialysis CKD and anemia. In vitro assays demonstrated that the erythroid progenitor cell frequency negatively correlated with sFas concentration ( r = −0.72, P < 0.001). There was decreased erythroid colony formation in vitro when CD34+ HSCs were incubated with a higher concentration of sFas protein (1.56 ± 0.29, 4.33 ± 0.53, P < 0.001). Our findings suggest that sFas is a potential predictor for ESA therapy in patients with nondialysis CKD and that elevated sFas could affect erythropoiesis in vitro.

Although the important role of fibroblast growth factor (FGF)23 on cardiac remodeling has been suggested in advanced chronic kidney disease (CKD), little is known about serum (s)FGF23 levels in patients with heart failure (HF) due to nonischemic cardiac disease (NICD) and early CKD. The present study aimed to investigate sFGF23 levels in NICD patients and identify the responsible factors for the elevation of sFGF23 levels. We prospectively measured sFGF23 levels in consecutive hospitalized NICD patients with early CKD (estimated glomerular filtration rate ≥ 40 ml·min−1·1.73 m−2) and analyzed the data of both echocardiography and right heart catheterization. Of the 156 NICD patients (estimated glomerular filtration rate range: 41–128 ml·min−1·1.73 m−2), the most severe HF symptom (New York Heart Association class III-IV, 53% vs. 33%, P = 0.015) was found in the above median sFGF23 (39.1 pg/ml) group compared with the below median sFGF23 group. sFGF23 levels were higher in patients with HF hospitalization history compared with those without HF [median: 46.8 (interquartile range: 38.8–62.7) vs. 34.7 (interquartile range: 29.6–42.4) pg/ml, P < 0.0001]. In the multivariate analysis, HF hospitalization was independently related to elevated sFGF23 levels ( P = 0.022). Both systolic dysfunction and high plasma aldosterone concentration were identified as predictors of high sFGF23 levels ( P < 0.05). Among the neurohormonal parameters, elevated sFGF23 levels were the only factor to predict a declining left ventricular ejection fraction ( P = 0.001). These findings suggest that the progression of HF per se contributes to the elevation of sFGF23 levels even in the early stages of CKD, which leads to further myocardial dysfunction, potentially creating a vicious cycle.
