Introduction: Very limited data are available on the long-term outcome of infective endocarditis (IE) and its determinants. The aim of this study was to identify the predictors of long-term mortality in patients affected by left sided IE (LSIE)., Methods: This was an historical retrospective observational study on prospectively collected data from patients with LSIE hospitalized in our Unit (January 2000-December 2017). Multiple variables relevant to history, physical examination, laboratory tests, echocardiography, comorbidities, complications and outcome were analysed by Cox regression to identify predictors of long-term mortality., Results: 414 patients were included, and followed up for a median of 39 months [IQR 11-74]. Median age was 59 years [range 3-89], and most patients were male. Over 50% showed at least one comorbidity. Hyperglycaemia, increased creatinine and an indication for surgery predicted in-hospital mortality, while a prior myocardial infarction, chronic kidney disease (CKD) on hemodialysis and a larger vegetation were independent predictors of 1-year mortality. At multivariate analysis, peripheral arterial disease (p= 0.017), hyperglycemia on admission (p=0.013) and a higher BMI (p=0.009) were independent predictors of long-term mortality in 1-year survivors. At multivariable Cox proportional hazard regression, peripheral arterial disease (p=0.002), hyperglycemia (p=0.041) and CKD on hemodialysis (p=0.025) confirmed to be independently associated with an increased risk of long-term mortality in the overall 414 patient cohort., Conclusions: Cardiovascular and metabolic risk signals, specifically peripheral arterial disease and hyperglicemia, affect long-term mortality of LSIE. An active and long-term follow up seems warranted in IE survivors showing these conditions at outset., (Copyright © 2021. Published by Elsevier B.V.)

Background: Few studies suggest an association between Enterococcal infective endocarditis (EIE) and colorectal disease, including colorectal neoplasia (CRN) and colorectal cancer (CRC). In this study, we analyze differences in prevalence, risk factors and outcome of CRN and CRC between EIE and Streptococcus gallolyticus infective endocarditis (SGIE)., Methods: Single center, observational study of 166 patients with definite EIE or SGIE. Clinical data were collected prospectively in a standardized IE protocol. Colonoscopy data were collected retrospectively on 90 patients., Results: 85 patients had EIE, 81 SGIE. EIE patients had a higher rate of prior cancer (20% vs 6%) and health-care associated infection (12% vs 1%), but similar mortality than SGIE. Colonoscopy performed in 90 patients showed intestinal diseases in 30 of 42 (71%) EIE patients vs. 40 of 48 (83%) SGIE patients (p = 0.174), with a predominance of CRN. Among 78 patients who underwent colonoscopy after IE diagnosis, no difference between EIE and SGIE was observed in the rate of non-neoplastic lesions (48% vs 47%), benign (32% vs 40%) or malignant (13% vs 15%) neoplastic lesions. Adverse events during colonoscopy were uncommon, although a careful handling of anticoagulation was required., Conclusions: EIE seems to be associated with colorectal disease, including colorectal neoplasia and colorectal cancer, to the same extent as SGIE. EIE should be considered a marker of colorectal neoplasia, even in patients with a clear health-care related acquisition. Colonoscopy is generally safe in EIE patients, and should be considered to early diagnose and treat colorectal disease., (Copyright © 2020 European Federation of Internal Medicine.
