Background: Chronic kidney disease (CKD) is a well-known mortality risk factor. The subendocardial viability ratio (SEVR) is one of the pulse wave analysis parameters that constitutes a non-invasive measure of coronary perfusion. We aimed to assess the prognostic value of the SEVR for cardiovascular outcome in non-dialysis CKD patients. Methods: A total of 98 CKD patients (mean age 60 years) were prospectively followed up from the date of the SEVR measurement until their death or the start of dialysis/transplantation, maximally up to 7.1 years (mean 5 years). According to the manufacturer’s instructions regarding normal SEVR values, the patients were divided into a low SEVR group (SEVR ≤130%, n = 26) and a normal SEVR group (SEVR > 130%, n = 72). Results: During the follow-up period, 13 patients (13.3%) suffered fatal and 23 patients (23.5%) suffered combined (non-fatal and fatal) cardiovascular events. In the patients who died of cardiovascular causes, the SEVR values were statistically significantly lower (130 vs. 154%; p = 0.017) than in those who survived. A Kaplan-Meier survival analysis showed that the cardiovascular survival rate in the low SEVR group of patients was statistically significantly lower (log-rank test: p < 0.001). Using an unadjusted Cox regression analysis, the patients in the low SEVR group had a 5.6-fold higher risk (95% CI: 1.8–17.3; p = 0.002) of fatal cardiovascular events and a 2.7-fold higher risk (95% CI: 1.1–6.3; p = 0.024) of combined fatal and non-fatal cardiovascular events. In the adjusted Cox regression model, the patients in the low SEVR group had a 16-fold higher risk (95% CI: 1.2–9.7; p = 0.004) of fatal cardiovascular events and a 7-fold higher risk (95% CI: 1–9.7; p = 0.009) of combined fatal and non-fatal cardiovascular events. Conclusions: An SEVR < 130% predicts fatal and non-fatal cardiovascular events in non-dialysis CKD patients.

Abstract Background and Aims In dialysis patients, cholesterol-lowering therapy with statins is less effective than in other high-risk patients. This may partly be explained by a shift from cholesterol synthesis, which is inhibited by statin treatment, towards cholesterol absorption, which is inhibited by ezetimibe. In line, markers of cholesterol absorption – such as campesterol - better predict atherosclerotic cardiovascular events than markers of cholesterol synthesis – such as lathosterol - in dialysis patients. We now investigated in our CARE FOR HOMe study whether a similar shift towards cholesterol absorption occurs in non-dialysis chronic kidney disease (CKD), and whether the campesterol / lathosterol ratio predicts outcome in non-dialysis CKD patients. Method Since 2008, 599 participants suffering from chronic kidney disease have been included into the CARE FOR HOME study, an observational cohort study. 555 patients had baseline samples available for analyses of the lathosterol / cholesterol ratio as a marker for cholesterol synthesis, and the campesterol / cholesterol ratio as a marker for cholesterol absorption. We excluded those participants who were currently treated with statins or other lipid lowering drugs, leaving 251 patients for this analysis. Participants were followed annually for major atherosclerotic cardiovascular events (MACE), defined as non-fatal acute myocardial infarction, non-fatal ischemic stroke, cerebrovascular / peripheral arterial or coronary revascularization, major amputation above the ankle and cardiovascular death. Additionally, all-cause death and the composite endpoint MACE and all-cause death were explored. We performed univariate (Model 1) and multivariate Cox regression analysis, adjusting for age, gender (Model 2), estimated glomerular filtration rate (eGFR), log-transformed albuminuria (Model 3), prevalent cardiovascular disease, current smoking, diabetes mellitus, systolic blood pressure and body mass index (Model 4). The primary hypothesis was that patients with a high campesterol / lathosterol ratio had a higher event rate. Results Neither lathosterol / cholesterol ratio (r = 0.022, p = 0.730), nor campesterol / cholesterol ratio (r = 0.042; p = 0.519) nor the campesterol / lathosterol ratio (r = -0.103; p = 0.105) correlated significantly with eGFR. During follow-up of 5.1 ± 2.1 years, 47 participants suffered from MACE, 46 participants died and 61 participants reached the composite endpoint of MACE or all-cause death. In univariate Cox regression analysis, campesterol / lathosterol ratio did not significantly predict atherosclerotic cardiovascular events (HR 0.740; 0.368 – 1.487), all-cause death (HR 0.564; 0.277 – 1.145) or the composite endpoint (HR 0.652; 0.355 – 1.196). After full adjustment, results were not different: Campesterol / lathosterol ratio was not significantly associated with all three endpoints: MACE (HR 1.064; 0.507 – 2.231), all-cause death (HR 0.818; 0.420 – 1.594) and MACE and all-cause death (HR 0.956; 0.525 – 1.744). Conclusion We did not observe a shift from cholesterol synthesis to cholesterol absorption across the spectrum of non-dialysis CKD. Campesterol / lathosterol ratio did not predict future MACE or all-cause death in non-dialysis CKD. These findings do not support the concept that CKD patients may preferentially benefit from ezetimibe rather than from statin treatment.

Background. There is an association between chronic kidney disease (CKD) and metabolic syndrome (MetS). We examined the joint association of CKD and MetS with incident cardiovascular (CVD) events in the Multiethnic Study of Atherosclerosis (MESA) cohort.Methods. We analyzed 2,283 Caucasians, 363 Chinese, 1,449 African-Americans, and 1,068 Hispanics in the MESA cohort. CKD was defined by cystatin C estimated glomerular filtration rate ≤ 60 mL/min/1.73 m2and MetS was defined by NCEP criteria. Cox proportional regression adjusting for age, ethnicity, gender, study site, education, income, smoking, alcohol use, physical activity, and total and LDL cholesterol was performed to assess the joint association of CKD and MetS with incident CVD events. Participants were divided into four groups by presence of CKD and/or MetS and compared to the group without CKD and MetS (CKD−/MetS−). Tests for additive and multiplicative interactions between CKD and MetS and prediction of incident CVD were performed.Results. During follow-up period of 5.5 years, 283 participants developed CVD. Multivariate Cox regression analysis demonstrated that CKD and MetS were independent predictors of CVD (hazard ratio, 2.02 for CKD, and 2.55 for MetS). When participants were compared to the CKD−/MetS−group, adjusted HR for the CKD+/MetS+group was 5.56 (95% CI 3.72–8.12). There was no multiplicative interaction between CKD and MetS (P=0.2); however, there was presence of additive interaction. The relative excess risk for additive interaction (RERI) was 2.73,P=0.2, and the attributable portion (AP) was 0.49 (0.24–0.74).Conclusion. Our findings illustrate that the combination of CKD and MetS is a strong predictor of incident clinical cardiovascular events due to presence of additive interaction between CKD and MetS.

Aim: To evaluate the clinical value of plasma D-dimer/fibrinogen ratio (DFR) in patients hospitalized for heart failure (HF). Methods: Clinical data of 235 patients were retrospectively analyzed. Kaplan–Meier method and Cox regression analysis were used to identify significant prognosticators. Results: The Kaplan–Meier analysis showed that a higher DFR level was significantly associated with an increase in the end point outcomes, including HF readmission, thrombotic events and death (log-rank test: p < 0.001). The multivariate Cox regression analysis showed that the high tertile of DFR was significantly associated with the study end points (HR: 2.18; 95% CI: 1.31–3.62; p = 0.003), compared with the low tertile. Conclusion: DFR is a reliable prognostic indicator for patients hospitalized for HF.

Purpose: To report the outcomes of bypass grafting (BG) vs endovascular therapy (EVT) in patients with non-dialysis-dependent chronic kidney disease (CKD) and chronic limb-threatening ischemia (CLTI). Materials and Methods: The CRITISCH Registry is a prospective, national, interdisciplinary, multicenter registry evaluating the current practice of all available treatment options in 1200 consecutive CLTI patients. For the purposes of this analysis, only the 337 patients with non-dialysis-dependent CKD treated by either BG (n=86; median 78 years, 48 men) or EVT (n=251; median age 80 years, 135 men) were analyzed. The primary composite outcome was amputation-free survival (AFS); secondary outcomes were overall survival (OS) and amputation-free time (AFT). All outcomes were evaluated in Cox proportional hazards models; the results are reported as the hazard ratio (HR) and 95% confidence interval (CI). Results: The Cox regression analysis revealed a significantly greater hazard of amputation or death after BG (HR 1.78, 95% CI 1.05 to 3.03, p=0.028). The models for AFT and overall survival also suggested a higher hazard for BG, but the differences were not significant (AFT: HR 1.66, 95% CI 0.78 to 3.53, p=0.188; OS: HR 1.41, 95% CI 0.80 to 2.47, p=0.348). The absence of runoff vessels (HR 1.73, 95% CI 1.15 to 2.60, p=0.008) was associated with a decreased AFS. The likelihood of amputation was higher in male patients (HR 2.21, 95% CI 1.10 to 4.45, p=0.027) and was associated with a lack of runoff vessels (HR 1.95, 95% CI 0.96 to 3.95, p=0.065) and myocardial infarction (HR 3.74, 95% CI 1.23 to 11.35, p=0.020). Death was more likely in patients without runoff vessels (HR 1.76, 95% CI 1.11 to 2.80, p=0.016) and those with a higher risk score (HR 1.73, 95% CI 1.03 to 2.91, p=0.038). Conclusion: This analysis suggested that BG was associated with poorer AFS than EVT in patients with non-dialysis-dependent CKD and CLTI. Male sex, previous myocardial infarction, and the absence of runoff vessels were additionally identified as predictors of poorer outcomes.

In this study, we evaluated the prognostic significance of multiple myeloma-1/interferon regulatory factor-4 (MUM1/IRF4) expression in B-cell chronic lymphocytic leukemia (B-CLL). Our results demonstrated that the absence of MUM1/IRF4 expression showed the highest relative risk among the factors analyzed in determining the probability for death in patients with B-CLL using univariate and multivariate Cox regression analysis. Patients without MUM1/IRF4 expression had significantly worse overall survival than did those with MUM1/IRF4 expression (52% cumulative survival, 63 months vs not reached, Kaplan-Meier survival analysis; P < .03, log-rank test). Patients with MUM1/IRF4 expression were more likely to have disease at low Rai stage and interstitial/nodular marrow involvement. Furthermore, only 1 of 11 patients with MUM1/IRF4 expression and interstitial/nodular marrow involvement died during a 100-month follow-up. Our results suggest that B-CLL with expression of MUM1/IRF4, indicative of postgerminal center origin, has a more favorable clinical course and that MUM1/IRF4 is an important prognostic marker in B-CLL.

Abstract Introduction Increased aortic pulse wave velocity (PWV) as a strong predictor of major advanced cardiovascular events (MACE) has a prognostic relevance in patients after myocardial infarction (MI). Several non-invasive methods have been proposed for the assessment of arterial stiffness, but the PWV values show significant differences according to the applied techniques. Cardiac magnetic resonance imaging (CMR) provides an accurate method to measure PWV and infarct size in patients after MI. Purpose Calculated PWV values of CMR based phase-contrast (PC) and invasively validated oscillometric methods were compared in this prospective observational study. We aimed to evaluate the cut-off PWV values for each method, while MACE predicted and validated the prognostic value of high PWV in post-infarcted patients in a 6-year follow-up. Methods 3D aortic angiography and PC velocity imaging was performed using a Siemens Avanto 1,5 T CMR device. Oscillometric based Arteriograph (AG) was used to assess PWV using direct body surface distance measurements. The comparison between the two techniques was tested. Patients received follow-up for MACE comprising all-cause death, non-fatal MI, ischemic stroke, hospitalization for heart failure and coronary revascularization. Event-free survival was analysed using Kaplan-Meier plots and log-rank tests. Univariable and multivariable Cox regression analysis was performed to identify outcome predictors. Results 75 patients (56 male, 19 female, average age: 56±13 years) referred for CMR were investigated, of whom 50 had coronary artery disease (CAD) including 35 patients with previous MI developing ischaemic late gadolinium enhancement (LGE) pattern. AG and CMR derived PWV values were significantly correlated (rho: 0,343, p&lt;0,05), however absolute PWV values were significantly higher for AG (median (IQR): 10,4 (9,2–11,9) vs. 6,44 (5,64–7,5); p&lt;0,001). Bland Altman analysis showed an acceptable agreement with a mean difference of 3,7 m/s between the two measures. In patients with CAD significantly (p&lt;0,01) higher PWV values were measured by AG and CMR, respectively. During the median follow-up of 6 years, totally 69 MACE events occurred. Optimized PWV cut-off values for MACE prediction were calculated (CMR: 6,47 m/s; AG: 9,625 m/s) by receiver operating characteristic analysis. Kaplan-Meier analysis in both methods showed a significantly lower event-free survival in case of high PWV (p&lt;0,01, respectively). Cox regression analysis revealed PWV for both methods as a predictor of MACE (PWV CMR hazard ratio (HR): 2,6 (confidence interval (CI) 1,3–5,1), PWV AG HR: 3,1 (CI: 1,3–7,1), p&lt;0,005, respectively). Conclusions Our study showed good agreement between the AG and CMR methods for PWV calculation. Both techniques are feasible for MACE prediction in postinfarcted patients. However, different AG and CMR PWV cut-off values were calculated to improve risk stratification. FUNDunding Acknowledgement Type of funding sources: None.

Abstract Background: Nuclear casein kinase and cyclin-dependent kinase substrate 1 (NUCKS1) was over-expressed in some tumors, including hepatocellular carcinoma (HCC). However, the clinical significance of NUCKS1 in HCC was still unclear. The aim of this study was to explore the expression and prognostic value of NUCKS1 in HCC. Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the relative mRNA expression of NUCKS1 in HCC tissues and corresponding adjacent normal tissues. The relationship between NUCKS1 expression and clinical characteristics of patients was analyzed by c2 test. Kaplan-Meier method and cox regression analysis were applied to estimate the prognostic value of NUCKS1 in HCC. Results: Compared with normal tissues, the relative mRNA expression level of NUCKS1 was significantly up-regulated in HCC tissues (P < 0.001). And high NUCKS1 expression was closely associated with tumor differentiation, TNM stage, vascular invasion and metastasis (P < 0.05). Kaplan-Meier analysis revealed that the overall survival of HCC patients with low expression of NUCKS1 was obviously longer than those with high NUCKS1 expression (log rank test, P = 0.001). NUCKS1 was an independent prognostic factor of HCC patients via univariate and multivariate cox regression analyses.Conclusions: NUCKS1 may be correlated with the progression of HCC and may serve as a potential factor for the prognosis of this disease.

Abstract Background and Aims Cardiovascular mortality is high in chronic kidney disease (CKD) patients. Recognizing patients with higher cardiovascular risk might help in their treatment. CHA2DS2-VASc score was originally used to predict cerebral infarction in patients with atrial fibrillation (AF). However, it is also useful in predicting outcome in different cardiovascular conditions, independent of the presence of AF. Therefore, the aim of our research was to assess the role of CHA2DS2-VASc score in cardiovascular mortality in CKD patients. Method Eighty-seven non-dialysis CKD patients from our outpatient clinic were included. At the time of inclusion, medical history data and standard blood results were collected and CHA2DS2-VASc score was calculated. Patients were followed for assigned time or until their death. Mean follow-up time was 1696.45±564.60 days. Results Descriptive statistics of our patients are presented in table 1. During follow-up 11 patients suffered from cardiovascular death. Univariate Cox regression analysis showed that CHA2DS2-VASc score is a significant predictor of cardiovascular mortality (HR: 2.19, CI: 1.42-3.37, p=0.001). In multivariate Cox regression analysis in which CHA2DS2-VASc score, serum creatinine, urinary albumin/creatinine, haemoglobin, high sensitivity CRP and intact PTH were included, CHA2DS2-VASc score was an independent predictor of cardiovascular mortality (HR: 2.04, CI: 1.20-3.45, p=0.008) (table 2). Conclusion CHA2DS2-VASc score is a simple and quick way to identify cardiovascular risk in CKD patients.

Background. There is very little published data on outcomes of COVID-19 among chronic kidney disease (CKD) patients. We compared the outcomes of COVID-19 in a tertiary care renal hospital among CKD V patients on hemodialysis (HD), peritoneal dialysis (PD), and dialysis initiation, in terms of duration of hospitalization, in-patient mortality, and 30-day mortality. Methods. A total of 436 CKD V patients, on either HD, PD, or dialysis initiation, with COVID-19 who were admitted at the National Kidney and Transplant Institute (NKTI) from March 13, 2020, to August 31, 2020, were included. Kaplan–Meier survival analysis was performed. Comparison of probability of mortality by group was performed using Log-Rank test. p values ≤0.05 were considered statistically significant. Results. Among 436 CKD V patients, 298 (68%) were on HD, 103 (24%) were on PD, and 35 (8%) required dialysis initiation. Overall in-hospital mortality was 34%; 38% were on HD, 20% on PD, and 37% on dialysis initiation. Total 30-day mortality was 27%; 32% were on HD, 26% on PD, and 16% on dialysis initiation. Median follow-up was 24 days. Among the 137 deaths recorded, total median time to death was 10 days; 8.5 days, 15.5 days, and 9 days for HD, PD, and dialysis initiation groups, respectively. Probability of mortality was significantly higher in HD patients versus PD patients ( p < 0.00001 ) and in the dialysis initiation group compared to PD patients ( p = 0.0234 ). Mortality probability, however, was not significantly different in HD patients versus the dialysis initiation group ( p = 0.63 ). Conclusion. Among CKD V patients diagnosed with COVID-19 at the NKTI, those on HD and on dialysis initiation had significantly higher in-hospital and 30-day mortality, compared to patients on PD.

Abstract Background To investigate the effect of nicergoline on the rate of complete corneal ulcer reepithelialization (CCUR) in diabetic rats with diabetic keratopathy. Methods Forty-eight streptozotocin-induced diabetic rats were randomly divided into two groups. The experimental group (n = 24) received nicergoline (10 mg.kg− 1.day− 1), while the control group (n = 24) received a placebo. A corneal epithelial defect was induced using a corneal diamond burr, and defect area was compared at time points of 0, 12, 24, 48 and 72 h after the injury using image analysis software. The probability of CCUR within 72 h was assessed using the Kaplan–Meier survival analysis log-rank test. Results When compared, 4 of the 24 rats (17%) in the placebo group and 12 of the 24 rats (50%) in the nicergoline group were found to have CCUR within 72 h (log-rank = 0.027). Cox regression analysis found no effect of the covariates blood glucose (P = 0.601) or weight (P = 0.322) on the corneal reepithelialization (survival) curve. Conclusions Nicergoline increased wound healing rates relative to placebo and may therefore be investigated as a treatment option in diabetic keratopathy.
