Background/Aim. Psoriasis as multisystemic inflammatory dis-ease is related with an increased cardiometabolic risk. The aim of the study was to analyze risk biomarkers, peripheral and renal arteries ultrasonography and echocardiography for subclinical atherosclerosis and metabolic disease in 106 subjects (66 psoriasis patients and 40 controls, 20 eczema patients and 20 healthy volunteers). Methods. In all exameenes following parameters were analyzed: body mass index (BMI), C-reactive protein, D-dimer, serum amyloid A (SAA), apolipoprotein (Apo) A1, ApoB, ApoB/Apo A1 index, fasting glucose, C-peptide, fasting insulinemia, homeostatic model assessment-insulin resistance (HOMA-IR), HOMA-?-cell, lipid profile, serum uric acid concentration (SUAC), 24-h proteinuria and microalbuminuria. Carotid, brachial, femoral and renal arteries ultrasonography, as well as echocardiography was also performed. Results. Five of 66 (7.6%) psoriasis patients had metabolic syndrome (not present in both control groups). The following variables were increased in patients with psoriasis compared to both control groups: BMI (p = 0.012), insulinemia (p < 0.001), HOMA-IR (p = 0.003), HOMA-? cell (p < 0.001), SUAC (p = 0.006), ApoB/ApoA1 ra-tio (p = 0.006) and microalbuminuria (p < 0.001). Also, increased C-peptide (p = 0.034), D-dimer (p = 0.029), triglycerides (p = 0.044), SAA (p = 0.005) and decreased ApoA1 (p = 0.014) were found in the psoriasis patients compared to healthy controls. HDL cholesterol was decreased in the psoriasis patients compared to the control group of eczema patients (p = 0.004). Common carotid (CIMT) and femoral artery intima-media thickness (FIMT) was significantly greater (p < 0.001) and the maximal flow speed (cm/s) in brachial artery significantly de-creased (p = 0.017) in the patients with psoriasis in comparison to both control groups. In multivariate logistic regression analysis, after the adjustment for confounding variables, the most important predictor of CIMT and FIMT was the diagnosis of psoriasis (p < 0.001). Conclusion. Cardiometabolic risk biomarkers and ultrasonographic signs of early atherosclerosis are correlated with the diagnosis of psoriasis, and not to generalized eczema. Psoriasis was found to be an independent risk factor for subclinical atherosclerosis. This article has been corrected. Link to the correction 10.2298/VSP1803334E

Background/Aim. Kidney injury molecule-1 (KIM-1) and aquaporin-1 (AQP-1) are potential early urinary biomarkers of clear renal cell carcinoma (cRCC). The aim of this study was to ascertain relationship between the urine concentrations KIM-1 and AQP-1 with tumor size, grade, pT stage and type of operation (radical or partial nephrectomy) in patients with cRCC. Methods. Urinary concentrations of urinary KIM-1 (uKIM-1) and urinary AQP-1 (uAQP-1) were determined by commercially available ELISA kits. The analysis included 40 patients undergoing partial or radical nephrectomy for cRCC and 40 age- and sex-matched healthy adult volunteers. Results. The median preoperative concentrations of KIM-1 in the cRCC group [0.724 ? 1.120 ng/mg urinary creatinine (Ucr)] were significantly greater compared with controls (healthy volunteers) (0.210 ? 0.082 ng/mgUcr) (p = 0.0227). Postoperatively, uKIM-1 concentration decreased significantly to control values (0.177 ? 0.099 ng/mgUcr vs 0.210 ? 0.082 ng/mgUcr, respectively). The size, grade and stage of tumor were correlated positively with preoperative uKIM-1 concentrations. Contrary to these results, concentrations of uAQP-1 in the cRCC group were significantly lower (0.111 ? 0.092 ng/mgUcr) compared with the control group (0.202 ? 0.078 ng/mgUcr) (p = 0.0014). Postoperatively, the concentrations of uAQP-1 increased progressively up to control values, approximately. We find no significant correlation between preoperative uAQP-1 concentrations and tumor size, grade and stage. Conclusion. uKIM-1 was found to be a reliable diagnostic marker of cRCC, based on its significantly increased values before and decreased values after the nephrectomy.

Background and Objectives: Factor VIII (FVIII) and the von Willebrand factor (vWF) are key components of hemostatic balance. Disruption of the vWF-ADAMTS13 axis, characterized by elevated vWF and reduced ADAMTS13 activity has been implicated in thrombotic disorders, including COVID-19-asscoiated coagulopathy, where this imbalance correlates with disease severity and mortality. This study evaluated the relationship between plasma FVIII and vWF levels and the severity of coronary artery disease (CAD), as assessed by the SYNTAX score. Methods: We enrolled 82 patients with chronic coronary syndrome (CCS) and a positive treadmill test who underwent elective coronary angiography. Based on the SYNTAX score, patients were divided into three groups: Group I (≤22), Group II (23–32), and Group III (≥33). Results: FVIII levels varied significantly (Group I: 2.25 ± 0.75; Group III: 2.97 ± 0.95; p = 0.007), with an OR of 3.632 (95% CI: 1.116–11.826; p = 0.03). vWF levels differed significantly across SYNTAX groups (Group I: 1.16 ± 0.59; Group II: 1.52 ± 0.62; Group III: 1.49 ± 0.80; p = 0.040). vWF > 1.75 was more frequent in Groups II and III, with an odds ratio (OR) of 4.909 (95% CI: 1.429–16.864; p = 0.01) for Group III vs. Group I. Fibrinogen and C-reactive protein (CRP) were elevated in patients with SYNTAX scores ≥33. In multinomial logistic regression analysis, FVIII emerged as the sole independent predictor of CAD complexity (p = 0.004), while the vWF showed significance in pairwise comparison (Group II vs. Group I; OR = 3.433, p = 0.049). Conclusions: This study demonstrated significant differences in hemostatic and inflammatory biomarkers across SYNTAX score categories reflecting CAD severity in CCS patients. FVIII emerged as an independent predictor of CAD complexity, while the vWF demonstrated significant associations in specific subgroup comparisons. The observed vWF-ADAMTS13 axis dysregulation supports the rationale for investigating vWF-targeted therapeutics, including agents such as caplacizumab, in cardiovascular disease management. These findings require validation in larger studies.

Background/Aim. Inflammation is the most important factor in the genesis of vascular complication in the endstage renal disease. The serum C-reactive protein (CRP) level is a sensitive marker of systemic inflammation as well as a predisposing factor for cardiovascular and all cause mortality in patients on hemodialysis. Albumin is the negative acute phase protein and its synthesis declines during the inflammation. The patients undergoing hemodialysis have a high prevalence of protein-energy malnutrition, due to reduced protein synthesis and increased degradation. The low serum albumin levels in these patients originate from the complex setting of conditions with systemic inflammatory response as a major cause, malnutrition and overhydratation. The aim of this study was to determine the prevalence of elevated CRP levels in the dialysis patients and to analyse its correlation with serum albumin levels and other parameters of nutritional status. Methods. The study included 49 patients on maintenance hemodialysis at the Department of Hemodialysis, Clinic of Nephrology, Military Medical Academy, Belgrade, Serbia. In order to analyse the parameters, the blood samples were taken during the arteriovenous fistula (AVF) puncture and before the second weekly dialyse. The following parameters were determined: serum levels of urea and creatinine before and after the dialysis procedure, CRP, hemoglobin, fasting glycemia, total cholesterol, triglycerides, albumins, iron, glycosylated hemoglobin (HbA1c), fasting insulinemia and C-peptide only before the dialysis. Results. Out of 49 patients on maintenance hemodialysis, 37 (75.5%) were males and 12 (24.5%) females with the average age of 56.04 ? 13.93 years. The average duration of the dialysis treatment was 7.37 ? 5 years. The high serum CRP levels (more than 3 mg/L) was found in 65.3% of patients. Singificantly more diabetic patients were observed in the group with the higher CRP levels (n = 12) compared to the group with the normal CRP levels (n = 3) (p ? 0.05). A significant positive correlation was found between the CRP value and urea values after the dialysis procedure. We found negative correlation between the CRP values and serum albumin, HbA1c, total cholesterol and triglyceride levels, with no statistical significance. Conclusion. Our study observed a high rate of inflammation in the dialysis patients presenting as high frequency of the elevated CRP levels in the examined group. Negative correlation between CRP levels and serum albumin as well as with some other parameters of nutritional status, suggests that chronic inflammation may be the missing link that actually connect protein energy malnutrition with high morbiditiy and mortality rate in these patients.

Background/Objectives: Renal failure (RF) and systolic heart failure (sHF) are very often associated with each other, and their synergistic influence can affect the prognosis of acute pulmonary embolism (aPE) patients. The aim of this study is to evaluate the associations between RF, sHF, and in-hospital mortality in patients with normotensive aPE. Methods: We analyzed data from the Regional PE Registry (REPER), and 1968 patients with CT pulmonary angiography-confirmed aPE who had a systolic blood pressure of 100 mmHg and higher, and for whom creatinine blood levels and left ventricular ejection fraction (LVEF) were measured at admission to hospital were enrolled. The patients were divided into four groups: the first group comprised patients without renal and systolic heart failure, the second those with RF (creatinine clearance less than 60 mL/min), the third those with sHF (LVEF less than 50%), and the fourth those with both RF and sHF. The primary endpoint of this study was in-hospital all-cause mortality. Results: There are significant differences between in-hospital mortality among the groups: 38/1247 (3.0%) vs. 63/514 (12.9%) vs. 10/99 (10.1%) vs. 20/108 (18.5%) (p < 0.001). In the multivariable regression model adjusted for age, right ventricular dysfunction, and troponin levels, the presence of renal failure, sHF, and both were independently associated with in-hospital all-cause mortality with ORs of 3.59 (95%CI 2.04–6.30, p < 0.001) vs. 3.97 (1.71–9.25, p = 0.001) vs. 6.39 (3.15–12.99, p < 0.001), respectively. Conclusions: The association of renal failure and systolic heart failure has a deleterious prognosis in patients with normotensive aPE.
