Outcomes of culture-negative vs. culture-positive infective endocarditis: the ESC-EORP EURO-ENDO registry.

AIM: Fatality of infective endocarditis (IE) is high worldwide, and its diagnosis remains a challenge. The objective of the present study was to compare the clinical characteristics and outcomes of patients with culture-positive (CPIE) vs. culture-negative IE (CNIE). METHODS AND RESULTS: This was an ancillary analysis of the ESC-EORP EURO-ENDO registry. Overall, 3113 patients who were diagnosed with IE during the study period were included in the present study. Of these, 2590 (83.2%) had CPIE, whereas 523 (16.8%) had CNIE. As many as 1488 (48.1%) patients underwent cardiac surgery during the index hospitalization, 1259 (48.8%) with CPIE and 229 (44.5%) with CNIE. The CNIE was a predictor of 1-year mortality [hazard ratio (HR) 1.28, 95% confidence interval (CI) 1.04-1.56], whereas surgery was significantly associated with survival (HR 0.49, 95% CI 0.41-0.58). The 1-year mortality was significantly higher in CNIE than CPIE patients in the medical subgroup, but it was not significantly different in CNIE vs. CPIE patients who underwent surgery. CONCLUSION: The present analysis of the EURO-ENDO registry confirms a higher long-term mortality in patients with CNIE compared with patients with CPIE. This difference was present in patients receiving medical therapy alone and not in those who underwent surgery, with surgery being associated with reduced mortality. Additional efforts are required both to improve the aetiological diagnosis of IE and identify CNIE cases early before progressive disease potentially contraindicates surgery.

Characteristics, management, and outcomes of patients with left-sided infective endocarditis complicated by heart failure: a substudy of the ESC-EORP EURO-ENDO (European infective endocarditis) registry.

AIMS: To evaluate the current management and survival of patients with left-sided infective endocarditis (IE) complicated by congestive heart failure (CHF) in the ESC-EORP European Endocarditis (EURO-ENDO) registry. METHODS AND RESULTS: Among the 3116 patients enrolled in this prospective registry, 2449 (mean age: 60 years, 69% male) with left-sided (native or prosthetic) IE were included in this study. Patients with CHF (n = 698, 28.5%) were older, with more comorbidity and more severe valvular damage (mitro-aortic involvement, vegetations >10 mm and severe regurgitation/new prosthesis dehiscence) than those without CHF (all p ≤ 0.019). Patients with CHF experienced higher 30-day and 1-year mortality than those without (20.5% vs. 9.0% and 36.1% vs. 19.3%, respectively) and CHF remained strongly associated with 30-day (odds ratio[OR] 2.37, 95% confidence interval [CI] [1.73-3.24; p < 0.001) and 1-year mortality (hazard ratio [HR] 1.69, 95% CI 1.39-2.05; p < 0.001) after adjustment for established outcome predictors, including early surgery, or after propensity matching for age, sex, and comorbidity (n = 618 [88.5%] for each group, both p < 0.001). Early surgery, performed on 49% of these patients with IE complicated by CHF, remained associated with a substantial reduction in 30-day mortality following multivariable analysis, after adjustment for age, sex, Charlson comorbidity index, cerebrovascular accident, Staphylococcus aureus IE, streptococcal IE, uncontrolled infection, vegetation size >10 mm, severe valvular regurgitation and/or new prosthetic dehiscence, perivalvular complication, and prosthetic IE (OR 0.22, 95% CI 0.12-0.38; p < 0.001) and in 1-year mortality (HR 0.29, 95% CI 0.20-0.41; p < 0.001). CONCLUSION: Congestive heart failure is common in left-sided IE and is associated with older age, greater comorbidity, more advanced lesions, and markedly higher 30-day and 1-year mortality. Early surgery is strongly associated with lower mortality but is performed on only approximately half of patients with CHF, mainly because of a surgical risk considered prohibitive.

Hospital admissions during Covid-19 lock-down in Germany: Differences in discretionary and unavoidable cardiovascular events.

BACKGROUND: A decline in hospitalization for cardiovascular events and catheter laboratory activation was reported for the United States and Italy during the initial stage of the Covid-19 pandemic of 2020. We report on the deployment of emergency services for cardiovascular events in a defined region in western Germany during the government-imposed lock-down period. METHODS: We examined 5799 consecutive patients who were treated by emergency services for cardiovascular events during the Covid-19 pandemic (January 1 to April 30, 2020), and compared those to the corresponding time frame in 2019. Examining the emergency physicians' records provided by nine locations in the area, we found a 20% overall decline in cardiovascular admissions. RESULTS: The greatest reduction could be seen immediately following the government-imposed social restrictions. This reduction was mainly driven by a reduction in discretionary admissions for dizziness/syncope (-53%), heart failure (-38%), exacerbated COPD (-28%) and unstable angina (-23%), while unavoidable admissions for ST-elevation myocardial infarction (STEMI), cardiopulmonary resuscitation (CPR) and stroke were unchanged. There was a greater decline in emergency admissions for patients ≥60 years. There was also a greater reduction in emergency admissions for those living in urban areas compared to suburban areas. CONCLUSIONS: During the Covid-19 pandemic, a significant decline in hospitalization for cardiovascular events was observed during the government-enforced shutdown in a predefined area in western Germany. This reduction in admissions was mainly driven by "discretionary" cardiovascular events (unstable angina, heart failure, exacerbated COPD and dizziness/syncope), but events in which admission was unavoidable (CPR, STEMI and stroke) did not change.

Bendamustine in heavily pre-treated patients with relapsed or refractory multiple myeloma.

PURPOSE: Treatment options for patients with relapsed and refractory multiple myeloma have improved since the introduction of immune-modulating agents such as lenalidomide and thalidomide. However, almost all patients relapse and suffer from an increasing amount of adverse events due to multiple lines of therapy that eventually lead to a reduced quality of life. METHODS: In this bicentric retrospective analysis, 58 patients who had been treated with either bendamustine monotherapy (62 % of the patients) or combined steroid therapy were included. Further inclusion criteria were at least relapsed disease. Patients had previously been treated with a mean of four lines of therapy (range 1-10). They received a median of three cycles of treatment. Dosage varied from 60 to 300 mg/m(2) (median 120 mg/m(2)) and was administered intravenously on day 1 and 2 of a 28-day cycle. RESULTS: Observed toxicity was mild and most commonly led to hematological side effects such as thrombopenia and anemia. Response rates were as follows: no complete response, 20 % partial response, 39 % minimal response, 27 % stable disease and 14 % progressive disease. Median overall survival (OS) was 17 months. Median event-free survival was 7 months. Patients who had not received a concomitant steroid had a median OS of 17 months compared to 13 months median OS for patients who had received a concomitant steroid. CONCLUSION: Bendamustine monotherapy is an effective treatment option for heavily pre-treated myeloma patients due to its favorable response rate and mild toxicity.
