RESUMEN
OBJECTIVE: This study aims to test the serum levels of soluble thrombomodulin (TM) in patients with chronic kidney disease (CKD)3-5 and to assess their connection with the different stages and severity of disease. METHODS: Sixty-seven patients with CKD are included, disease severity was evaluated accordingly to CKD staging and clinical data is collected. Nineteen healthy volunteers served as healthy controls. Serum soluble TM is analyzed by ELISA. RESULTS: The levels of soluble TM in all patients with CKD were significantly higher than those of healthy controls (p < 0.001). CKD5 patients showed higher serum levels of soluble TM, in comparison to CKD4 patients (p = 0.001), CKD3 patients (p < 0.001), and healthy controls (p < 0.001). The correlation analysis revealed significant correlation between serum soluble TM and disease severity (r = 0.714, p < 0.001). Serum soluble TM was found to be correlated with eGFR (r = -0.766; p < 0.001) and serum creatinine (r = 0.778, p < 0.001). CONCLUSION: Soluble TM concentrations significantly increase in the CKD patients and are associated with the severity of the disease. Soluble TM may play critical roles in the development of CKD, as a biomarker of endothelial cells damage, anticoagulation and anti-inflammation.

BACKGROUND: There is growing evidence for an association between chronic renal disease (CKD) and adverse cerebrovascular events because of the overlap of several risk factors. The purpose of this study is to examine the epidemiology of CKD and the characteristics of risk factors for CKD in the population with ischaemic stroke. METHODS: This retrospective study included 571 patients with ischaemic stroke. Estimated glomerular filtration rate (eGFR) was calculated by the Modification of Diet in Renal Disease (MDRD) study equation. Renal function was assessed according to the Kidney Disease Outcomes Quality Initiative (K/DOQI)-CKD classification. RESULTS: Study demonstrated that the major factors associated with CKD in the ischaemic stroke patients were age, diabetes mellitus, hypertension, systolic blood pressure, LDL cholesterol and serum uric acid. Diabetes mellitus (OR 4·146, 95% CI 1·047-16·418, P = 0·043), hypertension and diabetes mellitus (OR 3·574, 95% CI 1·248-10·234, P = 0·018), serum uric acid (OR 1·010, 95% CI 1·006-1·013, P < 0·001) and LDL cholesterol (OR 1·431, 95% CI 1·063-1·928, P = 0·018) were independent risk factors associated with CKD in the patients with ischaemic stroke. CONCLUSIONS: The patients with ischaemic stroke may be considered as a high-risk population for CKD and be aggressively managed for CKD prevention. The high prevalence of CKD in population with ischaemic stroke prompts the need for greater public awareness about risks of CKD.

OBJECTIVES: Chronic renal disease (CKD) is recognized as a worldwide public health problem. Traditional risk factors for CKD are also present in coronary artery disease (CAD). The purpose of this study is to examine the prevalence and characteristics of risk factors for CKD in the population with CAD. METHODS: Renal function was evaluated in 527 patients with CAD in order to assess characteristics of the incidence, risk factors for CKD in the population with CAD. In the present study in order to concentrate on evaluation for eGFR of the patients with CAD proteinuria is not included in the definition of CKD. RESULTS: Univariate analysis demonstrated that the major risk factors associated with CKD in the patients with CAD were age (P ≤ 0.001), smoking (P = 0.016), diabetes mellitus (P = 0.021), hypertension (P ≤ 0.001), and systolic blood pressure (P = 0.004). The percentages of patients with both hypertension and diabetes mellitus were significantly greater in the CKD3-4 group (P < 0.001). The results of multivariable analysis showed that hypertension (OR 1.925, 95% CI 1.196-3.098, P = 0.007), diabetes mellitus (OR 1.744, 95% CI 1.044-2.914, P = 0.034) and serum uric acid (OR 1.008, 95% CI 1.006-1.010, P ≤ 0.001) were independent risk factors for reduced eGFR. CONCLUSIONS: CKD is common and has a high prevalence in the population with CAD. Several risk factors are known to simultaneously affect heart and kidney. The patients with CAD may be considered as a high-risk population for CKD.

INTRODUCTION: This study aims to test the serum levels of interleukin-33 (IL-33) and soluble ST2 (sST2) in patients with chronic kidney disease (CKD) and to evaluate their association with disease severity. METHODS: Sixty-nine patients with CKD were enrolled, disease severity was assessed, and clinical data were collected. Twelve healthy volunteers served as healthy individuals. Serum IL-33 and sST2 were tested by enzyme-linked immunosorbent assay. RESULTS: The patients were classified into five categories based on their estimated glomerular filtration rate (eGFR). No difference was found as to the serum concentration of IL-33 between CKD patients and healthy individuals (p = 0.656), while a higher serum level of sST2 was found in CKD patients (p = 0.003). The correlation analysis revealed a significant correlation between the serum level of sST2 and disease severity (r = 0.586; p < 0.001). A higher level of sST2 was found in CKD patients with elevated parathyroid hormone (p = 0.001). Serum sST2 correlated with parathyroid hormone (r = 0.412; p < 0.001), serum phosphorus (r = 0.545; p < 0.001), and serum calcium (r = -0.494; p < 0.001). CONCLUSION: An elevated concentration of serum sST2 is found in CKD patients and correlates with disease severity. Serum sST2 may be also associated with parathyroid hormone disorder of CKD. The sST2 may have an important role in the development of CKD or as a marker of disease severity.
