Objective To clarify differences in clinical characteristics and outcomes between patients with infective endocarditis (IE) receiving long-term haemodialysis (HD group) and those not receiving haemodialysis (non-HD group). Methods Medical records of patients with IE, admitted to hospital between January 2010 and December 2017, were retrospectively studied. Clinical characteristics and outcomes were compared between HD and non-HD groups. Risk factors for IE were assessed by COX regression. Results Twenty-one HD and 143 non-HD patients were included. Predisposing heart conditions were more frequently observed in the non-HD versus HD group (90.9% versus 19.0%). Inappropriate antibiotic therapy rate before admission and proportion of methicillin-resistant Staphylococcus aureus and Enterococcus-associated IE was higher in the HD versus non-HD group. In the HD group, fewer patients underwent heart surgery (9.5% versus 51.7%), all-cause in-hospital mortality was higher (52.4% versus 21%), and survival rate was lower versus the non-HD group. COX regression analysis revealed that haemodialysis, use of central venous catheter (CVC) and inappropriate antibiotic therapy before admission increased IE mortality, while surgery improved long-term prognosis. Conclusions Haemodialysis patients with IE may have higher mortality and lower survival rates than patients with IE not receiving haemodialysis. Haemodialysis, use of CVC and inappropriate antibiotic therapy before admission may increase IE mortality. Surgery may improve long-term prognosis.

With scarce organ supply, a selection of suitable elderly candidates for transplant is needed, as well as auditing the long-term outcomes after transplant. We conducted an observational cohort study among our patient cohort >60 years old with a long follow up. (1). Patients and Methods: We used our database to study the results after transplant for 593 patients >60 years old who underwent a transplant between 2000–2017. The outcome was compared between live donor (LD; n = 257) recipients, an old-to-old (OTO, n = 215) group using an extended criteria donor (ECD) kidney, and a young-to-old (YTO, n = 123) group using a standard-criteria donor. The Kaplan−Meir method was used to calculate the patient and graft survival and Cox regression analysis in order to find risk factors associated with death. (2). Results: The 5- and 10-year patient survival was significantly better in the LD group (92.7% and 66.9%) compared with the OTO group (73.3% and 42.8%) and YTO group (70.9% and 40.6%) (p < 0.0001). The 5- and 10-year graft survival rates were 90.3% and 68.5% (LD), 61.7% and 30.9% (OTO), and 64.1% and 39.9%, respectively (YTO group; p < 0.0001 between the LD and the two DD groups). There was no difference in outcome between patients in their 60’s and their 70’s. Factors associated with mortality included: age (HR-1.060), DM (HR-1.773), IHD (HR-1.510), and LD/DD (HR-2.865). (3). Conclusions: Our 17-years of experience seems to justify the rational of an old-to-old allocation policy in the elderly population. Live-donor transplant should be encouraged whenever possible. Each individual decision of elderly candidates for transplant should be based on the patient’s comorbidity and predicted life expectancy.

Abstract Introduction Diabetes (DM) is the leading cause of induction of hemodialysis (HD), and both are major prognostic factors in patients with peripheral artery disease (PAD). However, the prognostic importance of baseline glycated hemoglobin (HbA1c) levels in PAD patients with and without HD is yet to be elucidated. Purpose We hypothesized that baseline HbA1c levels had different prognostic impacts after endovascular therapy (EVT) in between PAD patients with and those without regular HD. Methods This observational study included 643 consecutive patients who received EVT between 2013 and 2017. Each of 313 HD patients and 330 Non-HD patients was respectively divided into 2 groups by the comorbidity of diabetes, and DM patients were further divided into 3 subgroups depending on HbA1c level at the time of EVT; DM-Low (HbA1c: <6.0%), DM-Mid (6.1–7.0%), and DM-High (>7.1%) groups. The primary endpoint of this study was major amputation-free survival (AFS). Results HD group included significantly more patients presenting critical limb ischemia than Non-HD group (46.6% vs. 30.0%, p<0.001). During the observation period after EVT, there were 81 events (25.9%), including 55 death and 26 major amputations in HD group, and 45 events (13.6%), including 30 death and 15 major amputations in Non-HD group. Kaplan-Meier analysis revealed that DM patients had a significantly higher AFS rate in HD group (Log-rank: p=0.003, Figure A). In contrast, in Non-HD group, there was no statistical difference in AFS between DM and Non-DM patients (p=0.36). In Cox regression analysis in HD group, the higher HbA1c-DM group showed the higher hazard ratio (HR) for AFS (p=0.039, Figure B), and DM patients with HbA1c >6.0% had significantly higher HR than Non-DM patients. Whereas, in Non-HD group, HbA1c-DM class adversely associated with HR for AFS (p=0.003), even any classes did not reach statistical differences from Non-DM patients. Figure 1 Conclusions Comorbidity of diabetes at the time of EVT worsened long-term prognosis in PAD patients receiving regular HD, but not in those without HD. Additionally, baseline HbA1c levels oppositely affected prognosis in PAD patients with and without HD.

Monocyte to lymphocyte ratio (MLR) has been confirmed as a novel marker of poor prognosis in patients with coronary heart disease (CAD). However, the prognosis value of MLR for patients with CAD after percutaneous coronary intervention (PCI) needs further studies. In present study, we aimed to investigate the correlation between MLR and long-term prognosis in patients with CAD after PCI. A total of 3,461 patients with CAD after PCI at the First Affiliated Hospital of Zhengzhou University were included in the analysis. According to the cutoff value of MLR, all of the patients were divided into 2 groups: the low-MLR group (<0.34, n = 2338) and the high-MLR group (≥0.34, n = 1123). Kaplan–Meier curve was performed to compare the long-term outcome. Multivariate COX regression analysis was used to assess the independent predictors for all-cause mortality, cardiac mortality and MACCEs. Multivariate COX regression analysis showed that the high MLR group had significantly increased all-cause mortality (ACM) [hazard ratio (HR) = 1.366, 95% confidence interval (CI): 1.366-3.650, p = 0.001] and cardiac mortality (CM) (HR = 2.379, 95%CI: 1.611-3,511, p < 0.001) compared to the low MLR group. And high MLR was also found to be highly associated with major adverse cardiovascular and cerebrovascular events (MACCEs) (HR = 1.227, 95%CI: 1.003-1.500, p = 0.047) in patients with CAD undergoing PCI. MLR was an independent predictor of ACM, CM and MACCEs in CAD patients who underwent PCI.

THE OBJECTIVEof the study was to assess the impact of the count of interstitial CD3+, CD68+ and CD20+ cells on long-term prognosis of renal allograft (RA).PATIENTS AND METHODS.86 RA recipients with biopsy-proven according to the Banff 2013- 2017 criteria glomerulitis were enrolled in this retrospective study. The patients were subdivided into the following groups: 1) isolated glomerulitis with negative donor-specific antibodies (DSA) at the biopsy (n=53); 2) glomerulitis with positive DSA (n=22); 3) glomerulitis with undetermined DSA (n=11). Quantitative assay of interstitial positive cells was performed after immunohistochemical staining for CD68+, CD3+, CD20+. The Kaplan-Meier method and Cox proportional hazards regression model were used for the analysis of the relationship between interstitial CD3+, CD68+, CD20+ cells and risk of RA loss.RESULTS.CD68+ and CD3+ cells prevailed in interstitium in RA glomerulitis. CD20+ infiltrates were found in 60% of cases. CD20+ cells tended to form infiltrates, in 9 cases these infiltrates reached large sizes (≥ 50 CD20+ lymphocytes) and formed nodular structures. There was no difference in the count of interstitial CD3+ and CD68+ cells and in the presence of CD20+ infiltrates between DSA subgroups. Interstitial CD68+ ≥ 5 cells per field of view (FOV) (x400) and CD3+ ≥ 8 cells per FOV (x400), as well as the presence of large CD20+ infiltrates were associated with a lower RA survival (plog-rank < 0,05). Interstitial CD68+ (≥ 5 cells/FOV), CD3 + (≥ 8 cells/FOV) and the presence of large CD20+ interstitial infiltrates were independently associated with the risk of RA loss in the multivariable Cox regression analysis adjusted for DSA, cold and warm ischemia time (p < 0.05). CONCLUSION. Grade of interstitial infiltration by CD68+, CD3+ and CD20+ cells in RA glomerulitis could be independent predictor of RA loss.

e16020 Background: Papillary renal cell carcinoma (pRCC) represents the largest subgroup of non clear-cell kidney cancer. In this study we assessed tumour characteristics and long-term prognosis of patients with pRCC in comparison with conventional clear-cell cancer (ccRCC). Methods: We evaluated 744 patients who had undergone renal surgery for RCC between 1990 and 2005. The mean follow-up was 5.6 years. Results: Both groups pRCC and ccRCC were alike concerning age, body mass index, and the incidence of regional lymph node or distant metastasis at diagnosis. The percentage of male patients was higher in pRCC than in ccRCC (73.8 vs. 60.3%, p = 0.006). Even though patients with pRCC presented more often with smaller (p = 0.039) and low grade tumours (p = 0.006), there was no statistically significant difference in tumour recurrence or tumour related death. Moreover, looking at the whole cohort Kaplan-Meier curves revealed no differences regarding tumour specific survival between pRCC and ccRCC (p = 0.94; 5-year survival 78% vs. 77%). However, we observed a trend towards an improved outcome for organ confined (pT1–2) cancer, but a significantly inferior prognosis for locally advanced stage (pT3–4) and/or metastatic papillary tumours at the time of renal surgery. However, applying multivariate analysis including age, sex, and tumour grade, histology could neither be retained as a significant independent prognostic marker in the metastatic setting (p = 0.068, cox regression analysis) nor in a subgroup analysis focussing on patients with advanced cancer (pT3–4 and/or N+/M+; p = 0.064, cox regression analysis). Conclusions: Even though pRCC and ccRCC differ significantly in many aspects including histology and genetic alterations, in all, their long term prognosis is comparable. As we could not confirm a favourable clinical course for pRCC in general, standardized aftercare programmes and - if necessary - systemic treatment, especially in the era of novel targeted drugs, are also needed for this common RCC subtype. In addition, routine histologic subtyping of pRCC is strongly recommended. No significant financial relationships to disclose.

Abstract Funding Acknowledgements Type of funding sources: None. Background/Introduction: Previous clinical studies have underlined the prognostic role of platelet indices in acute coronary syndrome (ACS). However, the effect of their dynamic change during hospitalization has not thoroughly been examined. Purpose: We aimed to investigate the association between platelet indices on admission, on discharge and their change during hospitalization and the long-term prognosis of patients with ACS. Methods: Data from a randomized controlled trial recruiting ACS patients were analyzed in a survival analysis. Platelet count (PC), mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit (PCT) on admission and on discharge dichotomized at the median value, as well as the change between admission and discharge of each variable dichotomized at the zero value. Primary endpoints were major adverse cardiac events (MACE), defined as occurrence of cardiovascular death, non-fatal myocardial infarction, non-fatal stroke or hospitalization for unstable angina, while secondary endpoints were all-cause mortality, all-cause hospitalization and major or minor bleeding events. Results: The study included 252 individuals who were followed-up for a median of 39 months. In the univariate Cox regression analysis, only PC at discharge (HR 2.20, 95% CI 1.10-4.40), MPV at discharge (HR 0.48, 95% CI 0.25-0.94) and PC reduction during the hospitalization (HR 0.25, 95% CI 0.13-0.51) predicted MACE. PC reduction correlated with a lower MACE occurrence (adjusted HR 0.27, 95%CI 0.14-0.54) and lower risk of all-cause hospitalization (adjusted HR 0.36, 95%CI 0.19-0.68) in the multivariable Cox-regression analysis. Conclusion: PC change during hospitalization can be a substantial independent predictor of long-term prognosis of ACS patients.

Abstract Introduction Despite substantial progress in the medical and interventional treatment of acute myocardial infarction (AMI), a long-term prognosis in MI survivors remains unsatisfactory. The Managed Care in Acute Myocardial Infarction (MC-AMI, KOS-zawal) is the first program of a comprehensive, supervised care for patients with AMI to improve long-term prognosis. It includes acute intervention, complex revascularization, cardiac rehabilitation (CR), outpatient follow-up, and prevention of SCD. Purpose To assess the effect of MC-AMI on major adverse cardiovascular and cerebrovascular events (MACCE) in 12 months follow-up. Methods In this single-center, retrospective observational study we enrolled 1211 patients, out of which 719 consented for participation in MC-AMI and compared them to 1130 subjects in the control group. After propensity score matching two groups of 529 subjects each were compared. Cox regression was performed to assess the effect of MC-AMI on clinical endpoints. Results Primarily, MC-AMI has been proved to reduce MACCE rate by 40% in a 12-month observation. Participants of MC-AMI had a higher adherence to cardiac rehabilitation (98 vs. 14%) higher rate of scheduled revascularisation (coronary artery bypass grafting: 9.8% vs. 4.9%, p<0.001; elective percutaneous coronary intervention: 3.0% vs 2.1%, p<0.05) and ICD implantation (2.8% vs. 0.6%, p<0.05) compared to control. Multivariable Cox regression analysis revealed MC-AMI participation to be inversely associated with the occurrence MACCE at 12 months (HR=0.500, 95%Cl 0.349–0.718, p<0.001). Besides, older age, diabetes mellitus, hyperlipidemia, prior PAD, previous UA, and lower LVEF were significantly associated with the primary endpoint. 12-month FU - freedom from MACCE Conclusions MC-AMI is the first program of a comprehensive in-hospital and post-discharge care for AMI patients. MC-AMI improves prognosis by increasing the rate of patients undergoing CR, complete revascularization and ICD implantation, thus reducing MACCE rate by 40% in 12 months. Participation in MC-AMI is inversely related to mortality rate, recurrent MI and heart failure related hospitalization during 12 months.

The aim of the study. To compare different methods for assessing comorbidity in terms of its long-term predictive value after myocardial infarction (MI).Materials and methods. The analysis included 1176 patients with MI who were consecutively admitted to the hospital. The incidence of STsegment elevation MI was 60%; every second patient underwent endovascular intervention. All patients underwent an analysis of the severity of comorbidity according to the CIRS system (Cumulative lllness Rating Scale), according to the CCI (the Charlson’s comorbidity index), the CDS scale of chronic diseases (Chronic Disease Score), as well as according to their own model ‘K9’ (patent RU2734993C1 dated 10.27.2020) based on the summation of nine diseases: type 2 diabetes mellitus, chronic kidney disease, atrial fibrillation, anemia, stroke, arterial hypertension, obesity, peripheral atherosclerosis, thrombocytopenia.Results. Long-term mortality was 12.1 %. In Cox regression analysis of long-term survival after MI, the K9 model showed the best operational characteristics with a p < 0.00001 level. In multivariate analysis, when comorbidity data were added to GRACE, an increase in the χ2 value for GARCE + CCI and GRACE + K9 to 102.5 and 99.3, respectively, and the values of the area under the ROC curve to 0.78 (0.74–0, 82) and 0.77 (0.72–0.81), respectively. Regardless of the initial level of risk assessed by the GRACE scale, severe comorbidity (four or more diseases according to the K9) significantly increased the relative risk of mortality. In patients with severe comorbidity, the predictive value of the GRACE scale was the lowest.Conclusions. Among the analyzed methods of assessing comorbidity, only CCI and its own K9 scale have an acceptable predictive value, allowing better adaptation of the GRACE scale for stratification of the long-term risk of death after MI. At the same time ‘K9’, based on the summation of nine previously described diseases, is much more convenient than CCI in practical application

Abstract Background Enteral feeding and parenteral nutrition (PN) using gastrostomy (GS) and a nasogastric tube feeding (NGT) and PN should be initiated for older patients based on their prognoses. This study aimed to investigate the long-term prognosis of patients aged ≥75 years who underwent enteral feeding via GS and NGT as well as PN. Methods A population-based cohort study was conducted using Japan’s universal health insurance claims in the Nara Prefecture. This study enrolled 3,548 patients aged ≥75 years who received GS (N=770), NGT (N=2,370), and PN (N=408) during hospital admissions between April 2014 and March 2016. The GS group was further categorized into secondary GS (N=400) with preceding NGT or PN within 365 days and primary GS (N=370) without preceding NGT or PN groups. In the secondary GS group, 356 (96%) patients received NGT (versus PN). The outcome was mortality within 730 days after receiving GS, NGT, and PN. Cox regression analyses in cases with or without malignant diseases, adjusted for sex, age, comorbidity, and hospital type, were performed to compare mortality in the groups. Results Of the 3,548 participants, 2,384 (67%) died within 730 days after the initiation of GS and NGT and PN. The 2-year mortality rates in the secondary GS, primary GS, NGT, and PN groups were 58%, 66%, 68%, and 83% in patients without malignancies and 67%, 71%, 74%, and 87% in those with malignancies, respectively. In the non-malignant group, Cox regression analysis revealed that secondary GS (hazard ratio (HR) = 0.43, 95% CI: 0.34–0.54), primary GS (HR = 0.51, 95% CI: 0.40–0.64), and NGT (HR = 0.71, 95% CI: 0.58-0.87) were statistically significantly associated with lower mortality compared with PN. Conclusions Approximately 58% to 87% patients aged ≥75 years died within 730 days after initiation of nutrition through GS, NGT, or PN. Patients with non-malignant diseases who received secondary GS exhibited better 2-year prognosis than those who received NGT or PN. Healthcare professionals should be aware of the effectiveness and limitations of enteral feeding and PN when considering their initiation.
