Abstract
INTRODUCTION Gram-negative organisms of the AACEK group, formerly known as HACEK, rarely cause endocarditis. CASE SERIES We present three cases of bacterial endocarditis, involving native and prosthetic valves, caused by AACEK organisms. In two patients, Cardiobacterium hominis was the responsible organism, and in a third, Aggregatibacter aphrophilus was implicated. A dental source of infection was identified in two patients, and in all three patients, the presentation of endocarditis was subacute. DISCUSSION This case series highlights the indolent nature of infection with the AACEK organisms. It also demonstrates the crucial role of multimodality imaging, especially transesophageal echocardiography, in the diagnosis of AACEk endocarditis of both native and prosthetic valves, and in delineating the extent of abscess in those with prosthetic valve infection.

Abstract
ABSTRACT Infective endocarditis is a potentially fatal infection of the endocardium or valves that can result from IV drug abuse. This article describes a patient with infective endocarditis masked by opioid abuse withdrawal symptoms. This challenging presentation brings to the forefront the need for clinicians to be aware of and understand the changing risk factors and demographics of patients with nonspecific infective endocarditis.

Abstract
Infective endocarditis in drug users commonly targets the tricuspid valves, whereas pulmonic valve endocarditis is a rare occurrence. Staphylococcus aureus rather than Streptococcus species is the culprit organism. Streptococcal pneumonia is also not commonly seen as an etiological agent for endocarditis. Here we present a case of a 57-year-old man with a history of HIV infection on antiretroviral therapy who was admitted for sepsis and found to have pneumococcal bacteremia with vegetation on a pulmonic valve. He had been vaccinated with both pneumococcal conjugate vaccine 13 and pneumococcal polysaccharide vaccine 23 at the time of his HIV diagnosis. Pulmonic valve endocarditis is unusual in the setting of pneumococcal bacteremia in HIV patients previously vaccinated for pneumococcal disease.

Eur J Cardiothorac Surg 2021; 59:878-886. [PMID: 33156910 DOI: 10.1093/ejcts/ezaa390] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 09/15/2020] [Accepted: 09/24/2020] [Indexed: 11/14/2022] Open
Abstract
OBJECTIVES The aim of this study was to compare the outcomes of tricuspid valve (TV) repair versus replacement for patients with infective endocarditis (IE). METHODS In this nationwide population-based cohort study, we identified 704 patients from Taiwan National Health Insurance Research Database who underwent TV surgery due to IE between 2000 and 2013. Of them, 412 (58.5%) underwent TV repair and 292 (41.5%) underwent TV replacement, and their perioperative and late outcomes were analysed. Confounding was reduced using the inverse probability of treatment weighting on propensity score. RESULTS After inverse probability of treatment weighting, the in-hospital mortality rate between the 2 groups was not significantly different. However, patients who received TV repair had lower rates of perioperative complications, including massive blood transfusion, de novo dialysis and deep wound infection; longer ICU and hospital stays; and higher hospital cost. Regarding late outcomes, TV repair was associated with lower risks of all-cause readmission [subdistribution hazard ratio (HR) 0.68, 95% confidence interval (CI) 0.60-0.78; P < 0.001], readmission for adverse liver outcomes (subdistribution HR 0.75, 95% CI 0.58-0.97; P = 0.025), new permanent pacemaker implantation (subdistribution HR 0.27, 95% CI 0.15-0.48; P < 0.001) and all-cause mortality (HR 0.60, 95% CI 0.51-0.71; P < 0.001) than TV replacement. CONCLUSIONS For IE, TV repair is associated with better early and late outcomes than TV replacement. A repair-first strategy is recommended for patients with IE for whom TV surgery is indicated.

Evolution of epidemiological characteristics of infective endocarditis in Greece. Int J Infect Dis 2021; 106:213-220. [PMID: 33711517 DOI: 10.1016/j.ijid.2021.03.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2020] [Revised: 02/27/2021] [Accepted: 03/04/2021] [Indexed: 11/21/2022] Open
Abstract
OBJECTIVE The clinical profile, management and outcome of infective endocarditis (IE) may be influenced by socioeconomic issues. METHODS A nationwide prospective study evaluated IE during the era of deep economic crisis in Greece. Epidemiological data and factors associated with 60-day mortality were analyzed through descriptive statistics, logistic and Cox-regression models. RESULTS Among 224 patients (male 72.3%, mean age 62.4 years), Staphylococcus aureus (n = 62; methicillin-resistant S. aureus (MRSA) 33.8%) predominated in the young without impact on mortality (p = 0.593), whilst Enterococci (n = 36) predominated in the elderly. Complications of IE were associated with mortality: heart failure [OR 2.415 (95% CI: 1.159-5.029), p = 0.019], stroke [OR 3.206 (95% CI: 1.190-8.632), p = 0.018] and acute kidney injury [OR 2.283 (95% CI: 1.085-4.805), p = 0.029]. A 60-day survival benefit was solely related to cardiac surgery for IE during hospitalization [HR 0.386 (95% CI: 0.165-0.903), p = 0.028] and compliance with antimicrobial treatment guidelines [HR 0.487 (95% CI: 0.259-0.916), p = 0.026]. Compared with a previous country cohort study, history of rheumatic fever and native valve predisposition had declined, whilst underlying renal disease and right-sided IE had increased (p < 0.0001); HIV infection had emerged (p = 0.002). No difference in rates of surgery and outcome was assessed. CONCLUSIONS A country-wide survey of IE highlighted emergence of HIV, right-sided IE and predominance of MRSA in the youth during a severe socioeconomic crisis. Compliance with treatment guidelines promoted survival.

Abstract
Background There has been a rise in the incidence of injection drug use and associated infective endocarditis. Methods The clinical outcomes of 39 patients admitted with injection drug use-associated infective endocarditis were collected with a mean follow-up of 14 months. The outcomes were compared for patients treated medically with those undergoing surgical intervention. Re sults: The mean age was 39 ± 11 years; 54% were female. Thirty-two patients (82%) had native and 7 (18%) prosthetic infective endocarditis. The tricuspid valve was affected in 17 patients (43%), the mitral in 10 (26%), the aortic in 4 (10%), and multiple valves in 8 (20%). Sixteen (41%) patients underwent surgery, and 23 (59%) were treated with medical therapy. The indications for surgery included heart failure, systemic emboli, recurrent infection, and vegetation size ≥10 mm. Patients undergoing surgery had a higher rate of paravalvular abscess (25% vs 0%, P = 0.02), valve perforation (37% vs 11%, P = 0.04), and mitral valve involvement (44% vs 13%, P = 0.06), whereas medically treated patients had higher tricuspid valve involvement (61% vs 19%, P = 0.02). During follow-up, 26% of medical and 31% of surgical cohort patients died (P = 0.7). Mortality was highest (54%) among those who continued medical management despite an indication for surgery. Univariate predictors of mortality were age (odds ratio [OR] 1.09, 95% confidence interval [CI]: 1.01-1.17; P = 0.02), heart failure (OR 6.9; 95% CI: 1.24-37.49; P = 0.02), septicemia (OR 4.40; 95% CI:0.99-19.54; P = 0.05), and shock (OR 10.8; 95% CI: 1.68-69.92; P = 0.01). Conclusions Despite contemporary therapy, patients with injection drug use-associated infective endocarditis remain at high risk of complications and poor clinical outcomes. These findings highlight the need for developing new care pathways and a team approach for effective management.

Abstract
Background Patients with injection drug use (IDU) have increased risk of developing infective endocarditis (IE). Previous studies have reported recurrent IE, increased duration of hospital stay, poor adherence and compliance as well as higher mortality and worse outcomes after surgery in the IDU-IE patient group. Further studies are needed to provide a basis for optimized care and prevention of readmissions in this population. This study aims to describe the clinical characteristics and outcomes among patients with IDU-IE. Methods Data of adults with IDU-IE and non-IDU-IE, treated between 2008 and 2017 at the Karolinska University Hospital in Stockholm were obtained from the Swedish National Registry of Infective Endocarditis. Clinical characteristics, microbiological results, treatment durations, results from echocardiography and in-hospital mortality were compared between the groups. Results Of the total 522 patients, 165 (32%) had IDU-IE. Patients with IDU-IE were younger than the patients with non-IDU-IE (mean age IDU-IE: 41.6 years, SD 11.9 years; non-IDU-IE: 64.3 years, SD 16.4 years; P < 0.01). No difference in distribution of gender was observed, 33% were females in both the IDU-IE and the non-IDU-IE group. History of previous IE (IDU-IE: n = 49, 30%; non-IDU-IE: n = 34, 10%; P < 0.01) and vascular phenomena (IDU-IE: n = 101, 61%; non-IDU-IE: n = 120, 34%; P < 0.01) were more common among patients with IDU-IE while prosthetic heart valves (IDU-IE: n = 12, 7%; non-IDU-IE: n = 83, 23%; P < 0.01) and known valvular disease (IDU-IE: n = 3, 2%; non-IDU-IE: n = 78, 22%; P < 0.01) were more common among patients with non-IDU-IE. Aetiology of Staphylococcus aureus (IDU-IE: n = 123, 75%; non-IDU-IE: n = 118, 33%; P < 0.01) as well as tricuspid (IDU-IE: n = 91, 55%; non-IDU-IE: n = 23, 6%; P < 0.01) or pulmonary valve vegetations (IDU-IE: n = 7, 4%; non-IDU-IE: n = 2, 1%; P < 0.01) were more common in the IDU-IE group. The overall incidence of IDU-IE decreased during the study period, while the incidence of definite IE increased (P < 0.01). Conclusions This study presents that patients with IDU-IE were younger, less frequently treated with surgery and had higher prevalence of vascular phenomena and history of previous IE, aspects that are important for improved management of this population.

Abstract
BACKGROUND Infective endocarditis (IE) in people who inject drugs (PWID) is an emergent public health problem. OBJECTIVES The purpose of this study was to investigate IE in PWID and compare it with IE in non-PWID patients. METHODS Two prospective cohort studies (ICE-PCS and ICE-Plus databases, encompassing 8,112 IE episodes from 2000 to 2006 and 2008 to 2012, with 64 and 34 sites and 28 and 18 countries, respectively). Outcomes were compared between PWID and non-PWID patients with IE. Logistic regression analyses were performed to investigate risk factors for 6-month mortality and relapses amongst PWID. RESULTS A total of 7,616 patients (591 PWID and 7,025 non-PWID) were included. PWID patients were significantly younger (median 37.0 years [interquartile range: 29.5 to 44.2 years] vs. 63.3 years [interquartile range: 49.3 to 74.0 years]; p < 0.001), male (72.5% vs. 67.4%; p = 0.007), and presented lower rates of comorbidities except for human immunodeficiency virus, liver disease, and higher rates of prior IE. Amongst IE cases in PWID, 313 (53%) episodes involved left-side valves and 204 (34.5%) were purely left-sided IE. PWID presented a larger proportion of native IE (90.2% vs. 64.4%; p < 0.001), whereas prosthetic-IE and cardiovascular implantable electronic device-IE were more frequent in non-PWID (9.3% vs. 27.0% and 0.5% vs. 8.6%; both p < 0.001). Staphylococcus aureus caused 65.9% and 26.8% of cases in PWID and non-PWID, respectively (p < 0.001). PWID presented higher rates of systemic emboli (51.1% vs. 22.5%; p < 0.001) and persistent bacteremia (14.7% vs. 9.3%; p < 0.001). Cardiac surgery was less frequently performed (39.5% vs. 47.8%; p < 0.001), and in-hospital and 6-month mortality were lower in PWID (10.8% vs. 18.2% and 14.4% vs. 22.2%; both p < 0.001), whereas relapses were more frequent in PWID (9.5% vs. 2.8%; p < 0.001). Prior IE, left-sided IE, polymicrobial etiology, intracardiac complications, and stroke were risk factors for 6-month mortality, whereas cardiac surgery was associated with lower mortality in the PWID population. CONCLUSIONS A notable proportion of cases in PWID involve left-sided valves, prosthetic valves, or are caused by microorganisms other than S. aureus.

Abstract
The aim of the study was to compare background characteristics, microbiology and outcome of patients with right-sided and left-sided intravenous drug use (IDU) associated infective endocarditis (IE). A nationwide retrospective study using the Swedish Registry on Infective Endocarditis between 2008 and 2019 was conducted. A total of 586 people with IDU-IE were identified and divided into left-sided (n = 204) and right-sided (n = 382) IE. Descriptive statistics, Cox-regression and Kaplan–Meier survival estimates were used. The mean age of patients in the left-sided group was 46 years compared to 35 years in the right-sided group, p < 0.001. Left-sided IE had a higher proportion of females. Staphylococcus aureus was the causative pathogen in 48% of cases in the left-sided group compared to 88% in the right-sided group. Unadjusted and adjusted long-term survival was better in right-sided IE compared to left-sided IE. Independent predictors of long-term mortality were increasing age, end-stage renal disease, nosocomial infection, brain emboli and left-sided IE. Left-sided IE was common in people with IDU but the proportion of females with left-sided IE was low. S. aureus was twice as common in right-sided IE compared to left-sided IE, and the long-term prognosis of right sided IDU-associated IE was better compared to left-sided IE despite the fact that few were operated.

Abstract
Infective endocarditis (IE) is characterized by bacterial or fungal masses that form in the cardiac chambers and valves, and in severe cases invade the endocardium or intra-cardiac vessels. Right-sided IE accounts for 5% to 10% of cases, with a low mortality cited at 6%. A history of intravenous drug abuse (IVDU) is present in 90% of isolated right-sided IE cases, with normal intra-cardiac anatomy prior to infection in approximately 80%. Nevertheless, up to 50% of patients require early surgical intervention which is associated with significant peri-operative morbidity. Echocardiography is the gold standard for diagnosis with a sensitivity of 80% for the transthoracic modality and 95% for transesophageal studies; it provides important clinical information regarding the severity of infection and development of secondary complications. This includes identification of active infective vegetations, healed IE, prosthetic valve IE, and abscess formation and rupture. Prompt clinical, microbiologic, and imaging assessment of patients with suspected left or right-sided IE is of paramount importance and is reflected in the modified Duke criteria, the well-validated algorithm for accurate and timely diagnosis of IE. Data suggests the criteria sensitivity may be decreased in right-sided IE only, and thus, care must be taken to perform skilled and detailed echocardiographic assessments of the right heart in suspected cases. Herein we provide a review of IE of the right heart, with a focus on pathophysiology and its echocardiographic presentation and characteristics.

Abstract
Males and females possess distinct biological differences that manifest in diverse risk profiles for acute and chronic diseases. A well-documented example of this is ischemic stroke. It has been demonstrated that older females have greater prevalence of, and worse outcome after, ischemic stroke than do males and younger females. Loss of estrogen after menopause is heavily implicated as a contributing factor for this phenomenon; however, there is mounting evidence to suggest that certain risk factors tend to occur more often in older females, such as hypertension and atrial fibrillation, while others more adversely affect females than they do males, such as diabetes and smoking. Sex-specific risk factors, such as oral contraceptive use and menopause, could also contribute to the discrepancy in stroke prevalence and outcome. Additionally, there is evidence to suggest that females tend to present with more nontraditional symptoms of acute stroke than do males, making it more difficult for clinicians to correctly identify the occurrence of a stroke, which may delay the administration of thrombolytic intervention. Finally, certain sociodemographic factors, such as the fact that females were more likely to live alone prior to stroke, may contribute to poorer recovery in females. This review will explore the various co-morbidities and sociodemographic factors that contribute to the greater prevalence of and poorer outcome after stroke in older females and will highlight the critical need for considering sex as a predisposing biological variable in stroke studies.

Abstract
AIMS Antibiotic administration, severity of injury, and debridement are associated with surgical site infection (SSI) after internal fixation of open fractures. We sought to validate a time-dependent treatment effect of antibiotic administration. PATIENTS Consecutive open fracture patients at a level 1 trauma center with minimum 30-day follow-up were identified from an orthopaedic registry from 2013-2017. METHODS The primary endpoint was SSI within 90 days. A threshold time to antibiotic administration associated with SSI was ascertained by receiver-operator analysis. A Cox proportional hazards model adjusted for age, smoking, and drug use determined the treatment effect of antibiotic administration within the threshold period. RESULTS Ten percent of 230 patients developed a SSI. There was a trend for patients who did not develop an SSI to receive antibiotics earlier than those who did develop an SSI (61 minutes, IQR 33-107 vs 83 minutes, IQR 40-186), p=0.053). Intravenous antibiotic administration after 120 minutes of presentation of an open fracture to emergency department was significantly associated with a 2.4 increased hazard of surgical site infection (p=0.036) within 90 days. CONCLUSION Antibiotic administration greater than 120 minutes after ED presentation of an open fracture was associated with an increased risk of SSI.

Abstract
Inflammatory heart disease (IHD) is a group of diseases that includes pericarditis, myocarditis, and endocarditis. Although males appear to be more commonly affected than females, IHD can be seen in any age group. While the disease can be self-limiting leading to full recovery, affected individuals can develop chronic disease, suggesting that identification of primary triggers is critical for successful therapies. Adding to this complexity, however, is the fact that IHD can be triggered by a variety of infectious and non-infectious causes that can also occur as secondary events to primary insults. In this review, we discuss the immunological insights into the development of IHD as well as a mechanistic understanding of the disease process in animal models.

Abstract
PURPOSE The purpose of this study was to describe left-sided infective endocarditis (LSIE) in persons who inject drugs (PWID) and compare that group to PWID with non-LSIE and to non-PWID with LSIE. METHODS Retrospective single-center study of adult IE patients from 2011 to 2018. RESULTS Of the 333 patients in our cohort, 54 were PWID with LSIE, 75 were PWID with non-LSIE, and 204 were non-PWID with LSIE. When comparing LSIE vs non-LSIE in PWID, the LSIE group was older (median age 35 vs 28.5, p < 0.01), had fewer S. aureus infections (59% vs 92%, p < 0.01), was more likely to have cardiac surgery (31% vs 13%, p < 0.01), and had a higher 10-week mortality (22% vs 5%, p < 0.01). When comparing PWID with LSIE to non-PWID with LSIE, the PWID group were younger (median age 35 vs 46, p < 0.01); had more frequent multi-valve involvement (33% vs 19%, p = 0.04), Staphylococcus aureus infections (54% vs 27%, p < 0.01), and previous IE (24% vs 8%, p < 0.01); and experienced more strokes (54% vs 31%, p < 0.01). Ten-week mortality was similar for LSIE in both PWID and non-PWID (24% vs 20%, p = 0.47). CONCLUSIONS LSIE in PWID is not uncommon. Compared to non-LSIE in PWID, valve surgery is more common and mortality is higher. For reasons that are unclear, stroke is more frequent in LSIE in PWID than in non-PWID with LSIE but mortality is no different.

Abstract
The annual incidence of infective endocarditis (IE) is estimated to be between 15 and 80 cases per million persons in population-based studies. The incidence of IE is markedly increased in patients with valve prostheses (>4 per 1,000) or with prior IE (>10 per 1,000). The interaction between platelets, microorganisms and diseased valvular endothelium is the cause of vegetations and valvular or perivalvular tissue destruction. Owing to its complexity, the diagnosis of IE is facilitated by the use of the standardized Duke-Li classification, which combines two major criteria (microbiology and imaging) with five minor criteria. However, the sensitivity of the Duke-Li classification is suboptimal, particularly in prosthetic IE, and can be improved by the use of PET or radiolabelled leukocyte scintigraphy. Prolonged antibiotic therapy is mandatory. Indications for surgery during acute IE depend on the presence of haemodynamic, septic and embolic complications. The most urgent indications for surgery are related to heart failure. In the past decade, the prevention of IE has been reoriented, with indications for antibiotic prophylaxis now limited to patients at high risk of IE undergoing dental procedures. Guidelines now emphasize the importance of nonspecific oral and cutaneous hygiene in individual patients and during health-care procedures.

Abstract
Cocaine can be responsible for many psychiatric and/or somatic disorders. The aim of this systematic literature review of data was to expose relations between cocaine use and pulmonary complications. Cocaine can be responsible for acute respiratory symptoms (cough, black sputum, hemoptysis, dyspnea, wheezing, chest pain) and for various pulmonary disorders including barotrauma (pneumothorax, pneumomediastinum, subcutaneous emphysema, pneumopericardium), airway damage, asthma, bronchiolitis obliterans with organizing pneumonia, acute pulmonary edema, alveolar hemorrhage, alveolar pneumonia with carbonaceous material, bullous emphysema, acute eosinophilic pneumonia, pulmonary granulomatosis caused by talc or cellulose, interstitial pneumonitis and pulmonary fibrosis, vasculitis, pulmonary hypertension, pulmonary embolism and pulmonary infarction, mycotic pulmonary arterial aneurysms, septic emboli, aspiration pneumonia, community-acquired pneumonia, HIV-related opportunistic infections, latent tuberculosis infection, pulmonary tuberculosis, lung cancer and crack lung. Some of these complications are serious and may have a fatal outcome. Pulmonary function tests, thoracic tomodensitometry, bronchial fibroscopy with bronchoalveolar lavage and lung scintigraphy may be an aid to the diagnosis of these pulmonary compications. Cocaine use must be sought in case of respiratory symptoms in young persons.

Abstract
PURPOSE OF REVIEW This review describes the normal structure and pathologic changes that affect the right-sided cardiac valves and chambers. RECENT FINDINGS The anatomy and pathology described have been known for many years. Knowledge of these findings has gained relevance. The pattern of endocarditis is changing. New diagnostic techniques have allowed better characterization of lesions responsible for cardiac dysfunction. Novel, less invasive interventions have made recognition of abnormalities more clinically relevant. There are many different pathologic entities that can affect the right-sided cardiac valves. These are discussed in this review.

Abstract
Introduction The microbial epidemiology differs between infective endocarditis (IE) patients with and without a history of injection drug use. We set out to determine the prevalence and microbial epidemiology of infective endocarditis in our region, the Southeastern USA, to determine if any changes need to be made in empiric antimicrobial treatment. Methods The electronic medical record was reviewed for patients with IE between January 2013 and July 2017, which revealed 299 cases. The cases were then sorted between patients with and without a history of injection drug use. The growth of their initial set of blood cultures and side of cardiac involvement were then recorded. Statistical analyses were run on the data sets. Results There were statistically significant effects associated with both methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas species infections occurring more often in individuals with active injection drug use, while streptococcus and enterococcus infections were more likely to occur in the population of individuals who do not inject drugs. Conclusion In IE patients who use or are suspected of injection drug use, first-line broad-spectrum antibiotics with excellent MRSA and Pseudomonas coverage are essential.

Abstract
Stroke is a heterogeneous disease in persons living with human immunodeficiency virus (HIV). HIV is thought to increase the risk of stroke through both HIV-related and traditional stroke risk factors, which vary with respect to the patient's age and clinical characteristics. Numerous studies show that detectable viremia and immunosuppression increase the risk of stroke across all ages, whereas traditional risk factors are more common in the aging population with HIV. As persons living with HIV age and acquire traditional stroke risk factors, the prevalence of stroke will likely continue to increase. Large- and small-vessel disease are the most common causes of stroke, although it is important to evaluate for infectious etiology as well. Research regarding the management of stroke in patients with HIV is scant, and recommendations often parallel those for the general population. Treatment of HIV and effective reduction of traditional stroke risk factors is important to reduce the risk of stroke in persons living with HIV. Future research will help elucidate the pathophysiology of HIV and stroke risk, investigate sex differences in stroke risk, and evaluate the safety and benefits of standard stroke preventative measures and HIV-specific interventions in this population.

Abstract
Background Isolated Tricuspid valve infective endocarditis is an infrequent diagnosis, the incidence of Tricuspid valve infective endocarditis accounts for 5% and up to 15% of IE cases. Aim To assess the prevalence and the echocardiographic characteristics of tricuspid valve endocarditis among patients presented to the echo lab of Ain Shams hospital from 1-1-2016 to 1-1-2017. Methods This is a retrospective study which included all patients presented to the echo lab of Ain Shams university hospital from 1st January 2016 to 1st January 2017, the total number of patients were 8376, patients with infective endocarditis were 278, and patients with tricuspid valve endocarditis were 51 patients respectively. Complete transthoracic echocardiography was done for all patients and data was retrieved from a locally designed electronic database of cardiology department at Ain shams hospitals. Results The incidence of TVIE was (17.7%) of all cases of IE, and (0.67%) of all cases attending the echo lab during the study period. The mean age group in our study was (31.1 ± 7.8) and about 84.3% of patient’s age was between 20 and 40 years. Higher incidence of IE was in males (90.2%) than in females (9.8%) with a ratio of 9:1. The vegetations were detected in one leaflet in 33 patients (64.7%), two leaflets in 9 patients (17.6%) and in the three TV leaflets in 7 patients (13.7). The most affected leaflet was the anterior leaflet that was affected in 38 patients constituting about 74.5% of patients. The size of vegetations was large >15 mm in 40 patients (78.4%). The most encountered echocardiographic complication was severe TR, detected in 40 patients (78.4%) and abscess formation was the least present, detected in only 2 patients (3.9%). Conclusion The incidence of TV IE is increasing with male gender predominance, and affects mainly young age groups. TV IE represented 0.6% of all patients, and 17.7% of IE cases. The main echocardiographic feature of TV IE is vegetations which were characterized by being large, highly mobile, and affecting mainly anterior TV leaflet. The main echocardiographic complication is severe TR, but abscess formation was infrequent.

Abstract
BACKGROUND Infective endocarditis is one of the most common infections among intravenous drug addicts. Its complications can affect many systems, and these can include acute renal failure. There is a scarcity of cases in the literature related to acute renal failure secondary to infective endocarditis treated with peritoneal dialysis. In this paper, the case of a 48-year-old Saudi male is reported, who presented with features suggestive of infective endocarditis and who developed acute kidney injury that was treated successfully with high tidal volume automated peritoneal dialysis. To our knowledge, this is the second report of such an association in the literature. CASE PRESENTATION A 48-year-old Saudi gentleman diagnosed to have a glucose-6-phosphate dehydrogenase deficiency and hepatitis C infection for the last 9 years, presented to the emergency department with a history of fever of 2 days' duration. On examination: his temperature = 41 °C, there was clubbing of the fingers bilaterally and a pansystolic murmur in the left parasternal area. The results of the blood cultures and echocardiogram were supportive of the diagnosis of infective endocarditis, and the patient subsequently developed acute kidney injury, and his creatinine reached 5.2 mg/dl, a level for which dialysis is essential for the patient to survive. CONCLUSION High tidal volume automated peritoneal dialysis is highly effective as a renal replacement therapy in acute renal failure secondary to infective endocarditis if no contraindication is present.

Abstract
PURPOSE OF THE REVIEW Infective endocarditis (IE) is a relatively infrequent infectious disease. It does, however, causes serious morbidity, and its mortality rate has remained unchanged at approximately 25%. Changes in IE risk factors have deeply impacted its epidemiology during recent decades but literature from low-income countries is very scarce. Moreover, prophylaxis guidelines have recently changed and the impact on IE incidence is still unknown. RECENT FINDINGS In high-income countries, the proportion of IE related to prior rheumatic disease has decreased significantly and has been replaced proportionally by cases related to degenerative valvulopathies, prosthetic valves, and cardiovascular implantable electronic devices. Nosocomial and non-nosocomial-acquired cases have risen, as has the proportion caused by staphylococci, and the median age of patients. In low-income countries, in contrast, rheumatic disease remains the main risk factor, and streptococci the most frequent causative agents. Studies performed to evaluate impact of guidelines changes' have shown contradictory results. The increased complexity of cases in high-income countries has led to the creation of IE teams, involving several specialties. New imaging and microbiological techniques may increase sensitivity for diagnosis and detection of IE cases. In low-income countries, IE remained related to classic risk factors. The consequences of prophylaxis guidelines changes are still undetermined.

Abstract
BACKGROUND Patients with infective endocarditis (IE) are at high risk for post-operative morbidity and death, which might be associated with drug abuse. The purpose of this study is to evaluate the impact of drug dependence on outcomes in patients who have IE and undergo valvular surgery (VS). PATIENTS AND METHODS The Nationwide/National Inpatient Sample 2001-2012 was queried to select patients with IE who had elective VS using International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis and procedure codes. Among them, patients with drug dependence (PDD) were identified, and their health status and post-operative outcomes were compared with those in patients without drug dependence (control group). Chi-square and Wilcoxon rank sum tests as well as multi-variable regression analysis were used for statistics. RESULTS A total of 809 (12.9%) PDD of the 6,264 patients who underwent VS were evaluated. They were younger compared with those in the control group (39.0 ± 10.8 y vs. 54.4 ± 14.8 y; p < 0.0001), had less age-related co-morbidities such as hypertension, diabetes mellitus, congestive heart failure, renal failure, obesity, but greater rates of alcohol abuse, liver disease, and psychoses. Despite the younger age and fewer co-morbidities, PDD compared with control patients were more likely to have post-operative complications develop overall (odds ratio [OR] = 1.6; 95% confidence interval [CI] 1.34-2.01), including infectious complications (OR = 1.5; 95% CI 1.27-1.78), specifically pneumonia (OR = 1.4; 95% CI 1.14-1.74) and sepsis (OR = 1.4; 95% CI 1.16-1.63), renal complications (OR = 1.5; 95% CI 1.23-1.77), and pulmonary embolism (OR = 1.9; 95% CI 1.44-2.52). Further, PDD had 11% longer hospital length of stay than those in the control groups (p < 0.0001). We did not find significant difference in hospital deaths, however, between these groups. CONCLUSION Drug dependence is associated with worse post-operative outcomes in patients with infective endocarditis who underwent valvular surgery and lengthens their hospital stay.

Abstract
People who inject drugs (PWID) are at risk for infective endocarditis (IE). Hospitalization rates related to misuse of prescription opioids and heroin have increased in recent years, but there are no recent investigations into rates of hospitalizations from injection drug use-related IE (IDU-IE). Using the Health Care and Utilization Project National Inpatient Sample (HCUP-NIS) dataset, we found that the proportion of IE hospitalizations from IDU-IE increased from 7% to 12.1% between 2000 and 2013. Over this time period, we detected a significant increase in the percentages of IDU-IE hospitalizations among 15- to 34-year-olds (27.1%–42.0%; P < .001) and among whites (40.2%–68.9%; P < .001). Female gender was less common when examining all the IDU-IE (40.9%), but it was more common in the 15- to 34-year-old age group (53%). Our findings suggest that the demographics of inpatients hospitalized with IDU-IE are shifting to reflect younger PWID who are more likely to be white and female than previously reported. Future studies to investigate risk behaviors associated with IDU-IE and targeted harm reduction strategies are needed to avoid further increases in morbidity and mortality in this rapidly growing population of young PWID.

Abstract
BACKGROUND Infective endocarditis is a microbial infection of the endocardial surface of the heart. Antibiotics are the cornerstone of treatment, but their use is not standardised, due to the differences in presentation, populations affected and the wide variety of micro-organisms that can be responsible. OBJECTIVES To assess the existing evidence about the clinical benefits and harms of different antibiotics regimens used to treat people with infective endocarditis. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE Classic and EMBASE, LILACS, CINAHL and the Conference Proceedings Citation Index on 30 April 2015. We also searched three trials registers and handsearched the reference lists of included papers. We applied no language restrictions. SELECTION CRITERIA We included randomised controlled trials assessing the effects of antibiotic regimens for treating possible infective endocarditis diagnosed according to modified Duke's criteria. We considered all-cause mortality, cure rates and adverse events as the primary outcomes. We excluded people with possible infective endocarditis and pregnant women. DATA COLLECTION AND ANALYSIS Three review authors independently performed study selection, 'Risk of bias' assessment and data extraction in duplicate. We constructed 'Summary of findings' tables and used GRADE methodology to assess the quality of studies. We described the included studies narratively. MAIN RESULTS Four small randomised controlled trials involving 728 allocated/224 analysed participants met our inclusion criteria. These trials had a high risk of bias. Drug companies sponsored two of the trials. We were unable to pool the data due to the heterogeneity in outcome definitions and the different antibiotics used.The included trials compared the following antibiotic schedules. The first trial compared quinolone (levofloxacin) plus standard treatment (anti-staphylococcal penicillin (cloxacillin or dicloxacillin), aminoglycoside (tobramycin or netilmicin) and rifampicin) versus standard treatment alone reporting uncertain effects on all-cause mortality (8/31 (26%) with levofloxacin plus standard treatment versus 9/39 (23%) with standard treatment alone; RR 1.12, 95% CI 0.49 to 2.56, very low quality evidence). The second trial compared daptomycin versus low-dose gentamicin plus an anti-staphylococcal penicillin (nafcillin, oxacillin or flucloxacillin) or vancomycin. This showed uncertain effects in terms of cure rates (9/28 (32.1%) with daptomycin versus 9/25 (36%) with low-dose gentamicin plus anti-staphylococcal penicillin or vancomycin, RR 0.89 95% CI 0.42 to 1.89; very low quality evidence). The third trial compared cloxacillin plus gentamicin with a glycopeptide (vancomycin or teicoplanin) plus gentamicin. In participants receiving gentamycin plus glycopeptide only 13/23 (56%) were cured versus 11/11 (100%) receiving cloxacillin plus gentamicin (RR 0.59, 95% CI 0.40 to 0.85; very low quality evidence). The fourth trial compared ceftriaxone plus gentamicin versus ceftriaxone alone and found no conclusive differences in terms of cure (15/34 (44%) with ceftriaxone plus gentamicin versus 21/33 (64%) with ceftriaxone alone, RR 0.69, 95% CI 0.44 to 1.10; very low quality evidence).The trials reported adverse events, need for cardiac surgical interventions, uncontrolled infection and relapse of endocarditis and found no conclusive differences between comparison groups (very low quality evidence). No trials assessed septic emboli or quality of life. AUTHORS' CONCLUSIONS Limited and very low quality evidence suggested that there were no conclusive differences between antibiotic regimens in terms of cure rates or other relevant clinical outcomes. However, because of the very low quality evidence, this needs confirmation. The conclusion of this Cochrane review was based on randomised controlled trials with high risk of bias. Accordingly, current evidence does not support or reject any regimen of antibiotic therapy for treatment of infective endocarditis.

Abstract
Right-sided infective endocarditis (RIE) is commonly due to Staphylococcus aureus and often involves the tricuspid valve (TV). A 31-year-old man with prior intravenous drug use presented with substernal pain, cough, dyspnoea and fever. Examination revealed a febrile, tachycardic male with peripheral infective endocarditis stigmata and right-heart failure. Laboratory parameters demonstrated leucocytosis, lactic acidosis and methicillin-resistant S. aureus (MRSA) bacteraemia. Echocardiography demonstrated multiple TV echodensities and chest imaging confirmed septic emboli. The MRSA species demonstrated 'vancomycin-creep', necessitating therapy with daptomycin and ceftaroline. Owing to persistent bacteraemia and septic shock, the patient underwent TV surgery, but continued to have a poor postoperative course with subsequent death. Indications for surgical therapy of RIE are limited to the European guidelines and most data are extrapolated from left-heart disease. MRSA exhibiting vancomycin-creep portends a poorer prognosis and requires aggressive therapy. We advocate the use of ceftaroline salvage therapy with daptomycin, pending further trials.

Abstract
Infective endocarditis is a common complication among injecting drug users. Disease risk among these patients is increased by the spread of HIV infection. In the following article, we discuss the exceptional clinical presentation of a 28-year-old patient who used intravenous drugs (heroin) for 10 years, had been infected with HIV for seven years and as a complication had developed Staphylococcus aureus infective endocarditis. The patient came to the hospital in serious condition, complaining of bodily pain, swelling of the legs and general weakness. During hospitalization, besides infective endocarditis, she was also diagnosed with anemia, toxic hepatitis, renal failure, ascites, sepsis, and pneumonia. A completely disrupted tricuspid valve, damaged aortic valve, and fibrosis of the mitral valve were detected. Echocardiographic and radiologic data showed that the patient's condition continued to deteriorate day by day, with significant progression of heart failure, ejection fraction decreasing from 45% to 10%, and development of myocarditis, hydrothorax and pericarditis. However, this progressive worsening of the patient's condition ceased when vancomycin was administered. To the authors' knowledge, this is the first such case described in the literature in which significant improvement was observed despite the patient's complex condition with associated complications.

Abstract
The incidence of isolated tricuspid valve infective endocarditis is increasing. Medical management is the mainstay of treatment but surgical intervention is required in a subset of patients. Surgical treatment options include valve excision and replacement or valve reconstruction. We searched PubMed and the Cochrane library to identify articles to be included in this review of surgical outcomes. References of selected articles were crosschecked for other relevant studies. Surgical management of tricuspid valve endocarditis can be achieved with satisfactory outcomes. However, the optimal indication and timing of surgery remain unclear, and the frequent association with intravenous drug use complicates management. Repair techniques are preferable though there is no clear evidence supporting one method over another.

Abstract
Infective endocarditis, a great masquerader, is a clinical entity which may present with a myriad of manifestations. Its changing epidemiological profile has been studied in the previous decades in both the developed and the developing nations. In this study, we strived to uphold the evolving clinical profile and its outcome from a government tertiary care hospital in Northern India. It was a descriptive, cross-sectional, observational study conducted over two years' period involving 44 patients diagnosed with definite infective endocarditis, according to modified Dukes' criteria. Demographic, clinical, microbiological, and echocardiographic data were analysed. Mean age of patients was 31 years. Rheumatic heart disease with regurgitant lesions was the commonest risk factor. Dyspnea and fever were the predominant symptom, and pallor and heart failure the commonest sign. Cultures were positive in 52% with Staphylococcus, the major isolate. Transesophageal echocardiography fared better than transthoracic one to define the vegetations. Mortality is reported in 4.5%. Prolonged duration of fever, pallor, hematuria, proteinuria, rheumatoid factor positivity, and large vegetations proved to be poor prognostic variables. Culture positive endocarditis, with persistent bacteremia, had higher incidence of acute renal failure. Right sided endocarditis was frequent in congenital lesions or IV drug user, whereas left sided endocarditis mostly presented with atrial fibrillation.

Abstract
Right-sided infective endocarditis (RIE) occurs predominantly in intravenous drug users in western countries, and it has a relatively good prognosis. Clinical features and prognosis of RIE occurring in non-drug users are not well known. We investigated the clinical findings of RIE in non-drug users. We retrospectively reviewed 345 cases diagnosed with IE. Cases with RIE or left-sided infective endocarditis (LIE) defined by the vegetation site were included and cases having no vegetation or both-side vegetation were excluded. Clinical findings and in-hospital outcome of RIE were compared to those of LIE. Among the 245 cases, 39 (16%) cases had RIE and 206 (84%) cases had LIE. RIE patients were younger (40 ± 19 yr vs 50 ± 18 yr, P=0.004), and had a higher incidence of congenital heart disease (CHD) (36% vs 13%, P<0.001) and central venous catheter (CVC) (21% vs 4%, P=0.001) compared to LIE patients. A large vegetation was more common in RIE (33% vs 9%, P<0.001). Staphylococcus aureus was the most common cause of RIE, while Streptococcus viridans were the most common cause of LIE. In-hospital mortality and cardiac surgery were not different between the two groups. CHD and use of CVC were common in non-drug users with RIE. The short-term clinical outcome of RIE is not different from that of LIE.

Abstract
Background: Infective endocarditis (IE) is a serious complication in immunosuppressive patients that has adverse effects. Objectives: The aim of this study was to define the characteristics, outcomes, and correlating factors of mortality in renal transplant recipients. Patients and Methods: Infective endocarditis was diagnosed in 22 patients from three renal transplant centers in Iran between 2000 and 2010. Modified Duke criteria were applied to confirm the diagnosis. Results: Twenty-two renal transplant patients with IE were evaluated. Blood culture results were positive in 81%. Enteroccous and group D non-enterococcal were the causative microorganisms in 31% and 25% of patients, respectively. In-hospital and 12-month mortality was 41% and the mortality rate was higher in older patients in comparison to younger patients. Overall, the rates of one-year disease-free patient and graft survival were 49% and 88%, respectively. Conclusions: Despite the availability of different and potent antibiotics, the mortality caused by IE remains considerably high. These patients are significantly prone to endovascular infections that affect the mortality and survival.

Abstract
Data on the incidence, associated factors, and prognosis of pericardial effusion (PE) in patients with infective endocarditis (IE) are scarce. Patients with native valve IE were prospectively followed in our center from 1990 to 2007. A logistic regression analysis was performed to identify independent variables associated with PE and mortality. We included 479 episodes of IE from 459 patients (70% men, mean age 51 years). Small-to-moderate PE was observed in 109 episodes (23%) and large-to-very large PE was observed in 9 episodes (2%). Patients with small-to-moderate PE had a greater prevalence of intravenous drug use (38% vs 23%) and more frequent right-sided IE than patients without PE (33% vs 17%). Patients with large-to-very large PE had a higher rate of systemic emboli (22% vs 18%) and periannular abscess (22% vs 6%) than patients without PE. Renal failure was associated with a higher risk of PE (odds ratio [OR] 2.1, 95% confidence interval [CI] 1.3 to 3.3); age was associated with a lower risk of PE (OR 0.98, 95% CI 0.97 to 0.99). One-year mortality of patients with IE with large-to-very large PE was higher than that of patients with small-to-moderate and absence of PE (56%, 18%, and 24%, respectively, p = 0.033). Large-to-very large PE increases the 1-year mortality of IE (OR 3.0, 95% CI 1.2 to 7.9). In conclusion, renal failure and younger age are associated with a higher risk of PE. Large-to-very large PE was associated with an increase in 1-year mortality.

Abstract
BACKGROUND Tricuspid valve (TV) infective endocarditis (IE) accounts for 15% of IE cases and usually is treated medically. Surgical intervention is rare, and understanding of treatment options is based on small series of patients. The purpose of this study was to describe the population and outcomes for isolated TV IE using The Society of Thoracic Surgeons Adult Cardiac Database. METHODS Between 2002 and 2009, 910 operations for TV IE were performed. Procedures included replacement, repair, and valvectomy. Healed IE was present in 31.4% (n = 286), and active IE, in 68.5% (n = 624). Baseline patient characteristics as well as operative mortality and morbidity were analyzed, and univariate statistical differences were evaluated by Kruskal-Wallis test and stratum-adjusted Mantel-Haenszel χ(2) tests. RESULTS The median age was 40 years, with 50.6% male. Replacement of the TV was the most common procedure (n = 490; 53.8%), followed by TV repair (n = 354; 38.9%) and valvectomy (n = 66; 7.2%). Overall operative mortality was 7.3%, with no significant difference in mortality among valvectomy 12%, repair 7.6%, and replacement 6.3% (p = 0.34). Compared with the active group, healed patients experienced a trend toward lower operative mortality (4.2% versus 8.6%; p = 0.06), lower complication rates (35.6% versus 51.4%; p = 0.0004), and shorter overall length of stay (12 versus 22 days; p < 0.0001). CONCLUSIONS Isolated TV operation for IE is a rare clinical entity with a similar operative mortality to left-sided IE operations. Repair and replacement of the TV had similar perioperative mortality. Patients in the healed TV IE group demonstrated lower complication rates, length of stay, and a trend toward decreased mortality.

Abstract
The Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Oncology (DGHO) here presents its updated recommendations for the treatment of documented fungal infections. Invasive fungal infections are a main cause of morbidity and mortality in cancer patients undergoing intensive chemotherapy regimens. In recent years, new antifungal agents have been licensed, and agents already approved have been studied in new indications. The choice of the most appropriate antifungal treatment depends on the fungal species suspected or identified, the patient's risk factors (e.g., length and depth of neutropenia), and the expected side effects. This guideline reviews the clinical studies that served as a basis for the following recommendations. All recommendations including the levels of evidence are summarized in tables to give the reader rapid access to the information.

Abstract
Right-sided infective endocarditis (RSIE) accounts for 5-10% of all cases of infective endocarditis (IE), and is predominantly encountered in the injecting drug user (IDU) population, where HIV and HCV coinfections often coexist. Staphylococcus aureus is the most common pathogen. The pathogenesis of RSIE is still not well understood. RSIE usually presents as a persistent fever with respiratory symptoms whilst signs of systemic embolisation as seen in left-sided IE are notably absent. The prompt diagnosis of RSIE thus requires a high index of suspicion. Transthoracic echocardiography (TTE) can detect the majority of RSIE, whilst transoesophageal echocardiography (TOE) can increase sensitivity. Virulence of the causative organism and vegetation size are the major determinants of prognosis. Most cases of RSIE resolve with appropriate antibiotic administration.

Abstract
The lifespan of HIV-infected patients is increasing, and cardiovascular diseases becoming a major comorbidity and leading cause of death in this population due to high prevalence of the cardiac risk factors and possibly due to the use of antiretroviral therapy. Aggressive reduction of these risk factors and treatment of cardiovascular diseases are crucial to decrease the cardiovascular mortality in these patients.

Abstract
In 2010, an 82-year-old patient received a diagnosis of stage IV chronic obstructive pulmonary disease, ischemic dilated cardiomyopathy, severe secondary pulmonary hypertension, atrial fibrillation with slow ventricular response, and severe tricuspid regurgitation. In December 2011, he was hospitalized for exacerbation of chronic obstructive pulmonary disease. The patient received antibiotics via injections (for 2 weeks through a peripheral venous catheter). In February 2012, he returned to the hospital with congestive heart failure and vascular purpura skin lesions. The echocardiography examination revealed a rupture of cordage afferent to the septal tricuspid valve. Because blood cultures were sterile after 10 days and no vegetation was revealed, the Duke criteria were not fulfilled. In March 2012, the patient returned with congestive heart failure, fatigue, and anorexia. Echocardiography evaluation then revealed attached septal tricuspid valve vegetation. The Duke criteria were now satisfied. The patient received antibiotics at doses recommended for infective endocarditis, with a favorable outcome.

Abstract
A 61-year-old patient with diabetes had a bio-prosthetic aortic valve replacement 3 years before admission. He complained of lethargy, night sweats, decreased appetite and erratic blood glucose with no weight loss. He had splinter haemorrhage and a systolic ejection murmur at the aortic area. Chest and abdominal examination revealed no abnormality. The erythrocyte sedimentation rate and C reactive protein were raised. He had several sets of blood cultures and he was started on empirical vancomycin, rifampicin and gentamicin. Transthoracic echocardiography showed vegetation on the base of the anterior mitral leaflet, which was confirmed by a trans-oesophageal echocardiography. Blood culture was positive for Haemophilus aphrophilus, and he was started on ceftriaxone for 6 weeks instead of vancomycin and rifampicin and continued gentamicin for 2 weeks. Follow-up echocardiography showed no evidence of vegetations. The patient recovered completely and he was discharged home.

Abstract
Cellulomonas spp. are often believed to be of low virulence. There are only a few reports of human infections. We report the first case of endocarditis caused by Cellulomonas in an intravenous drug abuser. The diagnosis of infective endocarditis (IE) in this case was definite using the Duke criteria. The course of the disease was complicated with a heart failure and possible mycotic aneurysm in the left leg. After the end of antimicrobial therapy aortic valve replacement was done because of severe heart failure.

Abstract
Infective endocarditis remains a life-threatening condition with an unchanging incidence and mortality of nearly 30% at 1 year. Surgery is required in 25–50% of acute infections and 20–40% of patients during convalescence. Operative procedures are often technically challenging and high-risk, often due to coexistent multisystem disease. However, international guidelines provide clear indications for surgical intervention, which are applicable for the majority of patients. These are not, however, supported by particularly robust clinical evidence and decision-making often needs to be tailored to the advancing age of the overall patient cohort, the presence of multisystem disease, comorbidities, prior antibiotic therapy of varying duration and the availability of surgical expertise. Native valve endocarditis will be the initial focus of this article, along with subgroups including prosthetic valve endocarditis. We present the treatment options for patients with infective endocarditis, evaluate the evidence-base that supports current clinical practice and attempt to provide an insight and subsequent recommendations for the timing of surgery.
