    We describe a man with the Marfan syndrome and a prior ascending aortic aneurysm resection who presented with knee pain and concern of endocarditis. Transesophageal echocardiogram showed no vegetations, and computed tomography angiogram of the heart showed a possible pseudoaneurysm. Cardiac catheterization and aortogram revealed the diagnosis of an aorto-right atrial fistula, which was then operatively repaired. This case highlights the role that cardiac catheterization with aortogram can play in the detection of aorto-atrial fistula.

    Full Text Available Abstract Aorto-atrial fistulas (AAF are rare but important pathophysiologic conditions of the aorta and have varied presentations such as acute pulmonary edema, chronic heart failure and incidental detection of the fistula. A variety of mechanisms such as aortic dissection, endocarditis with pseudoaneurysm formation, post surgical scenarios or trauma may precipitate the fistula formation. With increasing survival of patients, particularly following complex aortic reconstructive surgeries and redo valve surgeries, recognition of this complication, its clinical features and echocardiographic diagnosis is important. Since physical exam in this condition may be misleading, echocardiography serves as the cornerstone for diagnosis. The case below illustrates aorto-left atrial fistula formation following redo aortic valve surgery with slowly progressive symptoms of heart failure. A brief review of the existing literature of this entity is presented including emphasis on echocardiographic diagnosis and treatment.

    2016-01-01

    Fungal endocarditis is a rare and fatal condition. The Candida and Aspergillus species are the two most common etiologic fungi found responsible for fungal endocarditis. Fever and changing heart murmur are the most common clinical manifestations. Some patients may have a fever of unknown origin as the onset symptom. The diagnosis of fungal endocarditis is challenging, and diagnosis of prosthetic valve fungal endocarditis is extremely difficult. The optimum antifungal therapy still remains debatable. Treating Candida endocarditis can be difficult because the Candida species can form biofilms on native and prosthetic heart valves. Combined treatment appears superior to monotherapy. Combination of antifungal therapy and surgical debridement might bring about better prognosis.

    We describe a case of Lyme endocarditis which, to our knowledge, is the first reported case confirmed by molecular diagnostics in the United States. Valvular involvement as a manifestation of Lyme carditis is rare 4 . The first case describing a possible association between Lyme disease and cardiac valvular disease in the United States was published in 1993 5 . Since that time, there have been 2 cases of Lyme endocarditis confirmed by Borrelia positive 16S rRNA polymerase chain reaction (PCR) and sequencing from valvular tissue 8,10 and reported from Europe. We present the case of a 68-year-old male with progressive dyspnea had mitral valve perforation with severe mitral valve insufficiency and perforation seen on transesophageal echocardiogram. Subsequently resected valve tissue had sings of acute inflammation without organisms seen. Although blood and valve tissue cultures were negative, 16S rRNA PCR and sequencing demonstrated Borrelia burgdorferi. Lyme endocarditis can be a challenging diagnosis to confirm, given the rarity of cases and the need for molecular tools of resected valve tissue. It should be included among diagnostic possibilities in patients with culture-negative endocarditis who have exposure to ticks in endemic and emerging areas of Lyme disease. Copyright © 2018.

    Full Text Available Infective endocarditis is a disease caused by colonization and proliferation of infectious agents on the endothelial surface of the heart. Its clinical presentation is variable, depending upon conditions of the patient, such as immunosuppression, presence of prosthetic material, intravenous drug use, and the etiologic agent. Diagnosis is usually established through the addition of elements such as medical history, physical examination, results of blood cultures, echocardiography and other aids. We present the case of an adult male who came to the hospital with fever and symptoms and signs of acute heart failure. The presence of a systolic murmur was documented in the aortic area, and the echocardiogram revealed severe valve regurgitation and a vegetating lesion on the bicuspid aortic valve. He required valve replacement and completed antibiotic treatment based on the sensitivity of the Streptococcus mitis strain that was demonstrated in the blood cultures.

    Full Text Available As formas de eosinofilia pulmonar constituem um grupo heterogêneo definido pela presença de um ou dois critérios: infiltrado pulmonar com eosinofilia sanguínea e/ou eosinofilia tissular caracterizada por eosinófilos demonstrados na biópsia pulmonar ou no lavado broncoalveolar. Embora o infiltrado inflamatório seja composto de macrófagos, linfócitos, neutrófilos e eosinófilos, a presença de eosinofilia é um marcador importante para o diagnóstico e tratamento. A apresentação clínica e radiológica pode revelar eosinofilia pulmonar simples, pneumonia eosinofílica crônica, pneumonia eosinofílica aguda, aspergilose broncopulmonar alérgica e eosinofilia pulmonar associada à doença sistêmica, como na síndrome de Churg-Strauss e na síndrome hipereosinofílica. A asma está frequentemente associada, podendo ser um pré-requisito, como na aspergilose broncopulmonar alérgica e na síndrome de Churg-Strauss. Nas doenças com acometimento sistêmico, a pele, o coração e o sistema nervoso são os órgãos mais comprometidos. A apresentação radiológica pode ser considerada como típica, ou pelo menos sugestiva, para três formas de eosinofilia pulmonar: pneumonia eosinofílica crônica, aspergilose broncopulmonar alérgica e pneumonia eosinofílica aguda. A etiologia da eosinofilia pulmonar pode ser de causa primária (idiopática ou secundária, compreendendo causas conhecidas, como drogas, parasitas, infecções por fungos e micobactérias, irradiação e toxinas. A eosinofilia pulmonar pode também estar associada a doenças pulmonares difusas, doenças do tecido conectivo e neoplasias.Pulmonary eosinophilia comprises a heterogeneous group of diseases defined by eosinophilia in pulmonary infiltrates (bronchoalveolar lavage fluid or in tissue (lung biopsy specimens.

    Objective: To evaluate the CT features of aorto-right atrial fistula after aortic valve replacement (AVR) or ascending aortic replacement. Methods: Eighty-seven patients with aortic-right atrial fistula underwent CT after operation. The CT features were retrospectively analyzed. Fistula was measured according to maximum width of the shunt. Results: Aorto-right atrial fistula was detected in 87 patients after aortic valve replacement or ascending aortic replacement by CT scan. Among them, 25 patients were diagnosed as mild aorto-right atrial fistula, 47 patients as moderate, and 15 patients as severe. Thirty-seven patients underwent follow-up CT.Among them, 10 patients with mild to moderate aorto-right atrial fistula were considered to have complete regression, 8 patients with mild aorto-right atrial fistula considered to have incomplete regression, 14 patients with mild to moderate aorto-right atrial fistula considered to have stable condition, and 5 patients with moderate aorto-right atrial fistula considered to have progression at the 3-month follow-up. Conclusion: CT is a useful tool for defining aorto-right atrial fistula after AVR or ascending aortic replacement and for evaluating it in follow-up. (authors)

    Full Text Available Abstract Background For many patients with aorto-occlusive disease, where stent deployment is not possible, surgery remains the only treatment option available. The aim of this study was to assess the results of aortic reconstruction surgery performed in patients with critical ischaemia. Methods All patients with critical ischaemia undergoing surgery during 1991–2004 were identified from a prospectively maintained database. Mortality data was verified against death certificate data. Demographic and clinical data were obtained from the clinical notes and the radiology database. Disease was classified as: type I – limited to aorta and common iliac arteries; type II – external iliac disease and type III combined aortic, iliac and infra-inguinal disease. Results 86 patients underwent aortic replacement surgery all of whom had critical ischaemia consisting of: type I (n = 16; type II (n = 37 and type III (n = 33. The 30-day mortality rate was 10.4%, the one-year patient survival was 80%, and the 1-year graft survival was 80%. At 2 years the actual patient survival was 73% and no additional graft losses were identified. All patients surviving 30 days reported excellent symptomatic relief. Early, complications occurred in 6 (7% patients: thrombosis within diseased superficial femoral arteries (n = 4; haemorrhage and subsequent death (n = 2. Ten (14% late complications (> 12 months occurred in the 69 surviving patients and included: anastomotic stenosis (n = 3; graft thrombosis (n = 4, graft infection (n = 3. Four patients developed claudication as a result of more distal disease in the presence of a patent graft, and 1 patient who continued smoking required an amputation for progressive distal disease. Conclusion Aortic reconstruction for patients with extensive aorto-occlussive disease provides long-standing symptomatic relief for the majority of patients. After the first year, there is continued patient attrition due to co

    Full Text Available Infective endocarditis caused by Gemella morbillorum is a rare disease. In this report 67-year-old male patient with G. morbillorum endocarditis was presented. The patient was hospitalized as he had a fever of unknown origin and in the two of the three sets of blood cultures taken at the first day of hospitalization G. morbillorum was identified. The transthoracic echogram revealed 14 × 10 mm vegetation on the aortic noncoronary cuspis. After 4 weeks of antibiotic therapy, the case was referred to the clinic of cardiovascular surgery for valve surgery.

    Abstract This study investigated the possible relationship between endocarditis and overall and individual cancer risk among study participants in Taiwan. We used data from the National Health Insurance program of Taiwan to conduct a population-based, observational, and retrospective cohort study. The case group consisted of 14,534 patients who were diagnosed with endocarditis between January 1, 2000 and December 31, 2010. For the control group, 4 patients without endocarditis were frequency matched to each endocarditis patient according to age, sex, and index year. Competing risks regression analysis was conducted to determine the effect of endocarditis on cancer risk. A large difference was noted in Charlson comorbidity index between endocarditis and nonendocarditis patients. In patients with endocarditis, the risk for developing overall cancer was significant and 119% higher than in patients without endocarditis (adjusted subhazard ratio = 2.19, 95% confidence interval = 1.98–2.42). Regarding individual cancers, in addition to head and neck, uterus, female breast and hematological malignancies, the risks of developing colorectal cancer, and some digestive tract cancers were significantly higher. Additional analyses determined that the association of cancer with endocarditis is stronger within the 1st 5 years after endocarditis diagnosis. This population-based cohort study found that patients with endocarditis are at a higher risk for colorectal cancer and other cancers in Taiwan. The risk was even higher within the 1st 5 years after endocarditis diagnosis. It suggested that endocarditis is an early marker of colorectal cancer and other cancers. The underlying mechanisms must still be explored and may account for a shared risk factor of infection in both endocarditis and malignancy. PMID:27015220

    Full Text Available Abstract Although Staphylococcus capitis is considered to be a rare causative organism for prosthetic valve endocarditis, we report 4 such cases that were encountered at our hospital over the past 2 years. Case 1 was a 79-year-old woman who underwent aortic valve replacement with a bioprosthetic valve and presented with fever 24 days later. Transesophageal echocardiography revealed an annular abscess in the aorto-mitral continuity and mild perivalvular regurgitation. We performed emergency surgery 5 days after the diagnosis of prosthetic valve endocarditis was made. Case 2 was a 79-year-old woman presenting with fever 40 days after aortic valve replacement with a bioprosthesis. Transesophageal echocardiography showed vegetation on the valve, and she underwent urgent surgery 2 days after prosthetic valve endocarditis was diagnosed. In case 3, a 76-year-old man presented with fever 53 days after aortic valve replacement with a bioprosthesis. Vegetation on the prosthetic leaflet could be seen by transesophageal echocardiography. He underwent emergency surgery 2 days after the diagnosis of prosthetic valve endocarditis was made. Case 4 was a 68-year-old woman who collapsed at her home 106 days after aortic and mitral valve replacement with bioprosthetic valves. Percutaneous cardiopulmonary support was started immediately after massive mitral regurgitation due to prosthetic valve detachment was revealed by transesophageal echocardiography. She was transferred to our hospital by helicopter and received surgery immediately on arrival. In all cases, we re-implanted another bioprosthesis after removal of the infected valve and annular debridement. All patients recovered without severe complications after 2 months of antibiotic treatment, and none experienced re-infection during 163 to 630 days of observation. Since the time interval between diagnosis of prosthetic valve endocarditis and valve re-replacement ranged from 0 to 5 days, early surgical removal

    Purpose. The aim of our study was to review CT finding concerning secondary aorto-enteric fistulae (AEF). In particular, we aimed to evaluate signs of contrast medium extravasation from the aortic graft into the bowel (active bleeding), in correlation with clinical and surgical reports. Materials and methods. Clinical and CT findings were retrospectively evaluated in 13 surgically proven cases of AEF. All patients underwent spiral CT examination with biphasic contrast technique, before and 30 and 80 seconds after intravenous injection of 120-150 ml of contrast medium (Ultravist 370; flow rate 2.5-3 ml/sec). Late scans (240 seconds) were also acquired on surgical anastomoses. We used 3 mm (arterial phase) and 5 mm (venous phase slices. Results. At surgery, all patients presented a communication between the bowel and the aortic graft. At CT examination, all 13 patients presented one or more CT signs indicating AEF (perigraft soft tissue, perigraft fluid, ectopic air or bowel wall thickening). Moreover, in 6 out of 13 patients, contrast medium extravasation from the aortic graft into the small bowel (active bleeding) was detected with CT. Detection of active bleeding was possible because CT examinations were performed without oral administration of contrast medium. Conclusions. CT is easily and readily available and provides an accurate evaluation of the aorta and surrounding retroperitoneal tissues. In our study we were able to identify the CT sign of active bleeding in more than a half of the patients with acute gastrointestinal bleeding (66%). Hence, we suggest that patients undergo CT examination without oral contrast medium administration in order to better appreciate the presence of active bleeding [it

    Full Text Available Enterococci are normal inhabitants of gastrointestinal tract, being responsible for 5 to 18% of infective endocarditis and the incidence appears to be increasing. Eleven patients with enterococcal endocarditis were studied. In a case series group, 10 men (average 57 years and one woman (37 years were studied. Two patients had rheumatic heart disease, 5 patients arteriosclerotic disease and one patient chronic renal failure on hemodialysis. Ten patients were treated with ampicillin and gentamycin. Valve replacement was performed in 3 patients with aortic valve endocarditis, one on 8th day and two at the end of the treatment. Overall clinical cure was achieved in 9 patients. Two relapses occurred and 2 patients died as a result of refractory congestive heart failure and cerebral emboli. All of the enterococcal endocarditis cases were community acquired. In conclusion, infective endocarditis in patients with preexistent valvular heart disease, community acquisition and non specific symptoms with bacteriuria should be considered as enterococcal endocarditis.

    Infective endocarditis is defined by a focus of infection within the heart and is a feared disease across the field of cardiology. It is frequently acquired in the health care setting, and more than one-half of cases now occur in patients without known heart disease. Despite optimal care, mortality approaches 30% at 1 year. The challenges posed by infective endocarditis are significant. It is heterogeneous in etiology, clinical manifestations, and course. Staphylococcus aureus, which has become the predominant causative organism in the developed world, leads to an aggressive form of the disease, often in vulnerable or elderly patient populations. There is a lack of research infrastructure and funding, with few randomized controlled trials to guide practice. Longstanding controversies such as the timing of surgery or the role of antibiotic prophylaxis have not been resolved. The present article reviews the challenges posed by infective endocarditis and outlines current and future strategies to limit its impact. Copyright © 2017 American College of Cardiology Foundation.

    Full Text Available Endocarditis is one of the most prevalent forms of cardiac involvement in patients with lupus, as it is considered as one a life-threatening complication. Libman-Sacks endocarditis is common. Infective endocarditis can also cause complications within immunocompromised patients. The aim of this study is to determine particularities of endocarditis in patients with lupus and to look for distinguishing features between infectious or immunological origin. A retrospective study was conducted on patients with lupus presenting endocarditis. Lupus was diagnosed according to the American college of rheumatology criteria. The diagnosis of endocarditis was made based on the modified Duke criteria. The present case report studies seven cases of endocarditis. Six of these patients are women and the other one is a man. They are aged meanly of 29.4 years (extremes: 20-36. Fever was present in all the cases with a new cardiac murmur in six cases and a modification of its intensity in one case. Biologic inflammatory syndrome was present in six cases. Cardiac ultrasound performed in six cases made the diagnosis of endocarditis which involved the left heart valves in five cases and the right heart valves in one case. Valvular insufficiency was identified in six patients. The valve involvement was mitral in two cases, mitro-aortic in two others, aortic in the fifth one and tricuspid in the sixth one. Endocarditis was infectious in 4 cases, thanks to positive blood culture. The germs identified were gram negative bacilli in two cases, anaerobic organism in one case and gram positive cocci in one case. Candida albicans was isolated in one case. Libman-Sacks endocarditis was objectified in three cases. A combination of Libman-Sacks endocarditis with infectious endocarditis was diagnosed in one case. The treatment consisted of antibiotics in four cases with surgery in two cases. The outcome was favorable in five cases and fatal in the two others. Endocarditis in lupus

    ABSTRACT Infective endocarditis is life-threatening; identification of the underlying etiology informs optimized individual patient management. Changing epidemiology, advances in blood culture techniques, and new diagnostics guide the application of laboratory testing for diagnosis of endocarditis. Blood cultures remain the standard test for microbial diagnosis, with directed serological testing (i.e., Q fever serology, Bartonella serology) in culture-negative cases. Histopathology and molecular diagnostics (e.g., 16S rRNA gene PCR/sequencing, Tropheryma whipplei PCR) may be applied to resected valves to aid in diagnosis. Herein, we summarize recent knowledge in this area and propose a microbiologic and pathological algorithm for endocarditis diagnosis. PMID:28659319

    Full Text Available Aerococcus viridans is an infrequent human pathogen and few cases of infective endocarditis have been reported. A case involving a 69-year-old man with colon cancer and hemicolectomy 14 years previously, without recurrence, is reported. A diagnosis of native mitral valve endocarditis was established on the basis of clinical presentation, characteristic echocardiographic findings and pathological specimen examination after urgent valve replacement. A viridans endocarditis appears to be particularly virulent, requiring a surgical approach in four of 10 cases reported and death in one of nine. Given the aggressive nature of A viridans endocarditis and the variable time to diagnosis (a few days to seven months, prompt recognition of symptoms and echocardiography, in addition to blood cultures, should be performed when symptoms persist.

    2018-02-01

    Full Text Available Aorto-ventricular tunnel is an extremely rare congenital heart defect, consisting of failure of attachment of an aortic leaflet along the semilunar hinge. In all published reports the leaflet involved was either the right coronary leaflet, most frequently, or the left coronary leaflet, in most of the cases opening toward the left ventricle, with only one-eighth of the reported cases communicating with the right ventricle. Treatment of the aorto-ventricular tunnel has been anecdotally reported by interventional closure with a device and more frequently with surgical approach, either as an isolated malformation or as associated lesions. To the best of our knowledge, the presence of an aorto-ventricular tunnel of the non-adjacent aortic leaflet in transposition of the great arteries has never been reported. We have observed an aorto-ventricular tunnel involving the non-adjacent leaflet of the aortic root, which after arterial switch became the pulmonary root. The patient presented 18 years after the arterial switch with progressive dilatation of the right ventricle due to severe degree of pulmonary valve regurgitation, confirmed by echocardiography and cardiac MRI. Indication for surgery was given with the plan for a pulmonary valve implantation. Because of the intra-operative finding of disconnection of the anterior leaflet of the pulmonary valve (former aortic valve along the semilunar hinge, the surgical plan was modified and the anterior leaflet was attached to the valve annulus, with subsequent plasty in correspondence with the right and left commissurae to reduce the size of the dilated annulus to normal diameter. The post-operative course was uneventful, with extubation after few hours and discharge 4 days after surgery, with echocardiography showing trivial degree of pulmonary valve regurgitation. The patient remains in good conditions 6 months after surgery.

    2017-01-01

    Right-sided infective endocarditis (RSIE) is less common than left-sided infective endocarditis (IE), encompassing only 5–10% of cases of IE. Ninety percent of RSIE involves the tricuspid valve (TV). Given the relatively small numbers of TVIE cases operated on at most institutions, the purpose of this review is to highlight and discuss the current understanding of IE involving the TV. RSIE and TVIE are strongly associated with intravenous drug use (IVDU), although pacemaker leads, defibrillator leads and vascular access for dialysis are also major risk factors. Staphylococcus aureus is the predominant causative organism in TVIE. Most patients with TVIE are successfully treated with antibiotics, however, 5–16% of RSIE cases eventually require surgical intervention. Indications and timing for surgery are less clear than for left-sided IE; surgery is primarily considered for failed medical therapy, large vegetations and septic pulmonary embolism, and less often for TV regurgitation and heart failure. Most patients with an infected prosthetic TV will require surgery. Concomitant left-sided IE has its own surgical indications. Earlier surgical intervention may potentially prevent further destruction of leaflet tissue and increase the likelihood of TV repair. Fortunately, TV debridement and repair can be accomplished in most cases, even those with extensive valve destruction, using a variety of techniques. Valve repair is advocated over replacement, particularly in IVDUs patients who are young, non-compliant and have a higher risk of recurrent infection and reoperation with valve replacement. Excising the valve without replacing, it is not advocated; it has been reported previously, but these patients are likely to be symptomatic, particularly in cases with septic pulmonary embolism and increased pulmonary vascular resistance. Patients with concomitant left-sided involvement have worse prognosis than those with RSIE alone, due predominantly to greater likelihood of

    Abstract Infective endocarditis is an uncommon manifestation of infection with Histoplasma capsulatum. The diagnosis is frequently missed, and outcomes historically have been poor. We present 14 cases of Histoplasma endocarditis seen in the last decade at medical centers throughout the United States. All patients were men, and 10 of the 14 had an infected prosthetic aortic valve. One patient had an infected left atrial myxoma. Symptoms were present a median of 7 weeks before the diagnosis was established. Blood cultures yielded H. capsulatum in only 6 (43%) patients. Histoplasma antigen was present in urine and/or serum in all but 3 of the patients and provided the first clue to the diagnosis of histoplasmosis for several patients. Antibody testing was positive for H. capsulatum in 6 of 8 patients in whom the test was performed. Eleven patients underwent surgery for valve replacement or myxoma removal. Large, friable vegetations were noted at surgery in most patients, confirming the preoperative transesophageal echocardiography findings. Histopathologic examination of valve tissue and the myxoma revealed granulomatous inflammation and large numbers of organisms in most specimens. Four of the excised valves and the atrial myxoma showed a mixture of both yeast and hyphal forms on histopathology. A lipid formulation of amphotericin B, administered for a median of 29 days, was the initial therapy in 11 of the 14 patients. This was followed by oral itraconazole therapy, in all but 2 patients. The length of itraconazole suppressive therapy ranged from 11 months to lifelong administration. Three patients (21%) died within 3 months of the date of diagnosis. All 3 deaths were in patients who had received either no or minimal (1 day and 1 week) amphotericin B. PMID:25181311

    Full Text Available The concomitant presence of abnormal connection from three aortic valsalva sinuses to cardiac chambers is a rare complication of native aortic endocarditis. This case report presents a 37-year-old Iranian female patient who had native aortic valve endocarditis complicated by periannular abscess formation and subsequent perforation to multi-cardiac chambers associated with congestive heart failure and left bundle branch block. Multiple aorto-cavitary fistulas to right atrium, main pulmonary artery, and formation of a pocket over left atrial roof were detected by transthoracic echocardiogram (TTE. She had received a full course of antibiotics therapy in a local hospital and was referred to our center for further surgery. TTE not only detected multiple aorto-cavitary fistulas but also revealed large vegetation in aortic and mitral valve leaflets and also small vegetation in the entrance of fistula to right atrium. However, the tricuspid valve was not involved in infective endocarditis. She underwent open cardiac surgery with double valve replacement with biologic valves and reconstruction of left sinus of valsalva fistula to supra left atrial pocket by pericardial patch repair. The two other fistulas to main pulmonary artery and right atrium were closed via related chambers. The post-operative course was complicated by renal failure and prolonged dependency to ventilator that was managed accordingly with peritoneal dialysis and tracheostomy. The patient was discharged on the 25 day after admission in relatively good condition. The TTE follow-up one year after discharge revealed mild paravalvular leakage in aortic valve position, but the function of mitral valve was normal and no residual fistulas were detected.

    Full Text Available A criptococose pulmonar é uma doença causada pelo Criptococcus neoformans, um fungo unimórfico que possui distribuição mundial, existindo na mesma forma tanto no seu habitat natural quanto em animais e humanos. A doença possui apresentações clínica e patológica variáveis e pode manifestar-se tanto em pacientes com a imunidade normal como em imunocomprometidos, que representam a maioria dos casos. Neste trabalho são analisados os aspectos encontrados nas tomografias computadorizadas do tórax de 14 pacientes com criptococose pulmonar confirmada. Os achados mais freqüentes na tomografia do tórax foram as massas e os nódulos pulmonares. Outros aspectos observados foram as áreas de escavação, as consolidações, o espessamento do interstício peribroncovascular e o reticulado difuso. Massa pulmonar foi o achado isolado mais comum (64,2%, seguido dos nódulos isolados ou múltiplos (35,7%. Doença pulmonar difusa foi vista em apenas 14,2% dos casos. Os lobos superiores foram os mais comprometidos, sendo a doença mais comum nas regiões anteriores. A tomografia do tórax permitiu avaliar com precisão o grau de comprometimento do parênquima pulmonar.

    Full Text Available We present the case of aorto-iliac aneurysm in a patient with chronic renal failure requiring dialysis who were treated with an endovascular stent graft and, later on, submitted to kidney transplantation. A 53-year-old male with renal failure requiring dialysis presented with an asymptomatic abdominal aorto-iliac aneurysm measuring 5.0cm of diameter. He was treated with endovascular repair technique, being used an endoprosthesis Excluder®. After four months, he was successfully submitted to kidney transplantation (dead donor, with anastomosis of the graft renal artery in the external iliac artery distal to the endoprosthesis. The magnetic resonance imaging, carried out 30 days after the procedure, showed a good positioning of the endoprosthesis and adequate perfusion of the renal graft. In the follow-up, the patient presented improvement of nitrogenous waste, good positioning of the endoprosthesis without migration or endoleak. The endovascular repair of aorto-iliac aneurysm in a patient with end-stage renal failure under hemodialysis treatment showed to be feasible, safe and efficient, as it did not prevent the success of the posterior kidney transplantation.Apresentamos o caso de aneurisma aortoilíaco em um paciente com insuficiência renal crônica dialítica tratado com uma endoprótese vascular, sendo, após, submetido a transplante renal.

    Infective endocarditis is a serious disease which requires early diagnosis and adequate therapy. Echocardiography plays a key role in diagnosis and follow-up. Subacute infective endocarditis, however, is often difficult to prove echocardiographically due to its more subtle morphological changes. Also, echocardiography cannot reliably differentiate florid vegetations from residual structural changes of the affected valves in cured patients. Therefor, scintigraphy of infection and inflammation has been investigated as a complementary tool in diagnosis and follow-up of infective endocarditis. Immunoscintigraphy with the 99m Tc labelled anti granulocyte antibody in SPECT technique is complementary to echocardiography and seems to assess the floridity of the underlying inflammatory process. The combined use of both imaging modalities allows detection of virtually all cases of subacute infective endocarditis. SPECT immunoscintigraphy with the anti granulocyte antibody seems useful in doubtful cases of infective endocarditis, especially, if echocardiography is non-diagnostic and valve pathology pre-existing. the method may be used for follow-up and monitoring antibiotic therapy

    Fungal endocarditis is an extremely debilitating disease associated with high morbidity and mortality. Candida spp. are the most common isolated organisms in fungal endocarditis. It is most prevalent in patients who are immunosuppressed and intravenous drug users. Most patients present with constitutional symptoms, which are indistinguishable from bacterial endocarditis, hence a high index of suspicion is required for pursuing diagnosis. Diagnosis of fungal endocarditis can be very challenging: most of the time, blood cultures are negative or take a long time to yield growth. Fungal endocarditis mandates an aggressive treatment strategy. A medical and surgical combined approach is the cornerstone of therapy. Copyright © 2016 Elsevier Inc. All rights reserved.

  17. Infective Endocarditis during Pregnancy

    Yuan, S.

    2015-01-01

    Objective: Infective Endocarditis (IE) during pregnancy is a rare but grave condition. The diagnosis and management can be challenging, especially when the pregnant patient warrants a cardiac operation under cardiopulmonary bypass. The present article describes IE during pregnancy based on a series of published case reports in the literature. IE during pregnancy often causes embolic events and mycotic aneurysms. Two-thirds of IE in the pregnant patients requires timely or urgent cardiac surgery to alleviate patients deterioration. At least a 3-week antibiotic therapy is mandatory before cardiac surgery aiming at improving the patients. Conditions. During cardiac surgery, fetal heart rates may temporarily be slowed down but may gradually recover to normal after the operation. The fetal and maternal mortalities were 16.7% and 3.3%, respectively. The fetal deaths were apparently associated with a cardiac surgery during early pregnancy. Cardiopulmonary bypass, hypothermia and rewarming can adversely affect both the mother and the fetus by triggering placental deficits, fetal hypoxia and uterine contraction. Avoidance of cardiac operations before 24th gestation week and preferably deferred until after 28th gestation week have been a plausible argument as per the possible fetal deaths related to immaturity.

    Silver, Brian; Behrouz, Réza; Silliman, Scott

    2016-12-01

    Cerebrovascular complications of endocarditis occur in 25-70% of patients with infective endocarditis. The cornerstone of treatment is early initiation of antibiotic treatment, which significantly reduces the risk of embolization after 1 week of treatment. In general, thrombolysis and anticoagulation of these patients should be avoided, while antiplatelet therapy may be considered in those with other indications. Endovascular treatment of acute septic emboli is uncertain, but a few case reports have demonstrated benefit. Other complications of infective endocarditis include intracerebral hemorrhage, which may be predicted by the presence of two or more cerebral microbleeds on gradient echo sequences. Intracranial mycotic aneurysms can often be managed with serial imaging and coiled if there is evidence of failure to reduce in size, or enlargement.

    Full Text Available CONTEXT: The incidence of staphylococcal infection has been increasing during the last 20 years. OBJECTIVE: Report a case of staphylococcal endocarditis preceded by musculoskeletal manifestations, which is a rare form of clinical presentation. DESIGN: Case report. CASE REPORT: A 45-year-old-man, without addictions and without known previous cardiopathy, was diagnosed as having definitive acute bacterial endocarditis due to Staphylococcus aureus. Its etiology was community-acquired, arising from a non-apparent primary focus. In addition, the musculoskeletal symptoms preceded the infective endocarditis (IE by about 1 month, which occurred together with other symptoms, e.g. mycotic aneurysms and petechiae. Later, the patient showed perforation of the mitral valve and moderate mitral insufficiency with clinical control.

    Full Text Available A 74-year-old hemodialysis patient with a history of an atrial septum defect closure, coronary bypass surgery, and a St. Jude aortic prosthetic valve was diagnosed with pneumonia and volume overload. Blood cultures were positive for Listeria monocytogenes, and amoxicillin was given for 2 weeks. Immediately after discontinuation of amoxicillin, fever relapsed. Transthoracic and transesophageal echocardiography showed no sign of endocarditis. Given the fever relapse and 3 positive minor Duke criteria, an 18F-FDG PET-CT scan (18F-fluorodeoxyglucose-positron emission tomography-computed tomography scan was performed. This scan showed activity at the aortic root, proximal ascending aorta, and inferior wall of the heart, making Listeria monocytogenes endocarditis a likely explanation. Amoxicillin was given for 6 weeks with good clinical result. Diagnosing a life-threatening Listeria monocytogenes endocarditis can be challenging and an 18F-FDG PET-CT scan can be helpful.

    Infectious endocarditis remains both a diagnostic and a treatment challenge. A positive outcome depends on a rapid diagnosis, accurate risk stratification, and a thorough follow-up. Imaging plays a key role in each of these steps and echocardiography remains the cornerstone of the methods in use....... The technique of both transthoracic echocardiography and transoesophageal echocardiography has been markedly improved across the last decades and most recently three-dimensional real-time echocardiography has been introduced in the management of endocarditis patients. Echocardiography depicts structural changes...... with conventional CT (SPECT/CT). Of these methods, (18)F-FDG PET-CT carries the best promise for a future role in endocarditis. But there are distinct limitations with both SPECT/CT and (18)F-FDG PET-CT which should not be neglected. MRI and spiral CT are methods primarily used in the search for extra cardial...

    The posterior retroperitoneoscopic adrenalec tomy has several advantages compared with the transperitoneal approach such as a shorter and more direct route to the target organ, no breach of the intraperitoneal space, and no required retraction of the adjacent organs. It also is a safe procedure with a short learning curve.1 - 5 This report presents a challenging case of an extra-adrenal paraganglioma located in the aorto-caval space and managed using the retroperitoneal approach. A 39-year-old man was placed in the prone jackknife position, and three incisions were made in the right posterior abdominal wall for placement of the laparoscopic ports. The retroperitoneal space was entered with diathermy and blunt finger dissection, and retropneumoperitoneum was achieved with carbon dioxide insufflation pressure up to 18 mmHg. After identification of the right kidney and vessels, the tumor was meticulously dissected and excised with an energy device. The specimen was removed using a laparoscopic specimen retrieval bag, and the port sites were closed in layers. The operative time was 130 min, and the total blood loss was 30 ml. The tumor was diagnosed as a moderately differentiated extra-adrenal paraganglioma. The Von Hippel-Lindau gene mutation was detected using next-generation sequencing. The posterior retroperitoneoscopic approach is a safe, feasible, and effective method for excising an extra-adrenal paraganglioma even in the aorto-caval space. The authors suggest that this procedure is a useful surgical option for treatment of an aorto-caval paraganglioma for selected patients and by experienced surgeons.

    Purpose. To assess the effectiveness of endovascular treatment of anastomotic pseudoaneurysms (APAs) following aorto-iliac surgical reconstruction. Materials. We retrospectively evaluated 21 men who, between July 2000 and March 2006, were observed with 30 APAs, 13 to the proximal anastomosis and 17 to the distal anastomosis. The patients had had previous aorto-iliac reconstructive surgery with a bypass due to aneurysm (15/21) or obstructive disease (6/21). The following devices were used: 12 bifurcated endoprostheses, 2 aorto-monoiliac, 4 aortic extenders, 1 stent-graft leg, and 2 covered stents. Follow-up was performed with CT angiography at 1, 3, and 6 months after the procedure and yearly thereafter. Results. Immediate technical success was 100%. No periprocedural complications occurred. Four patients died during follow-up from causes not related to APA, and 1 (treated for prosthetic-enteric fistula) from sepsis 3 months after the procedure. During a mean follow-up of 19.7 months (range 1-72 months), 2 of 21 occlusions of stent-graft legs occurred 3 and 24 months after the procedure (treated with thrombolysis and percutaneous transluminal angioplasty and femorofemoral bypass, respectively) and 1 type I endoleak. Primary clinical success rate was 81% and secondary clinical success was 91%. Conclusion. Endovascular treatment is a valid alternative to open surgery and can be proposed as the treatment of choice for APAs, especially in patients who are a high surgical risk. Further studies with larger series and longer follow-up are necessary to confirm the long-term effectiveness of this approach

    Treatment of aorto-ostial in-stent restenosis lesions represents a challenge for interventional cardiologists. Excessive protrusion of the stent into the aorta may lead to multiple technical problems, such as difficult catheter reengagement of the vessel ostium or inability to re-wire through the stent lumen in repeat interventions. We describe a balloon assisted access to protruding stent technique in cases where conventional coaxial engagement of an aorto-ostial protruding stent with the guide catheter or passage of the guide wire through the true lumen is not feasible. This technique is applicable both in coronary and peripheral arteries. © 2015 Wiley Periodicals, Inc.

    To evaluate the safety and technical success of inferior vena cava (IVC) filter retrieval in the setting of aorto-iliac arterial strut penetration. IVC filter registries from six large United States IVC filter retrieval practices were retrospectively reviewed to identify patients who underwent IVC filter retrieval in the setting of filter strut penetration into the adjacent aorta or iliac artery. Patient demographics, implant duration, indication for placement, IVC filter type, retrieval technique and technical success, adverse events, and post procedural clinical outcomes were identified. Arterial penetration was determined based on pre-procedure CT imaging in all cases. The IVC filter retrieval technique used was at the discretion of the operating physician. Seventeen patients from six US centers who underwent retrieval of an IVC filter with at least one strut penetrating either the aorta or iliac artery were identified. Retrieval technical success rate was 100% (17/17), without any major adverse events. Post-retrieval follow-up ranging from 10 days to 2 years (mean 4.6 months) was available in 12/17 (71%) patients; no delayed adverse events were encountered. Findings from this series suggest that chronically indwelling IVC filters with aorto-iliac arterial strut penetration may be safely retrieved.

    Nonbacterial thrombotic endocarditis is a rare cause of valvular heart disease, most commonly associated with advanced malignancy. The morbidity of this kind of endocarditis lies in its tendency to embolize, while the valve function is usually preserved. The central nervous system is the most common site of embolization, leading to ischemic stroke. We report a case of nonbacterial thrombotic endocarditis complicated by intracerebral hemorrhage as the first manifestation of adenocarcinoma of the lung. The endocarditis led to severe aortic regurgitation. In view of the advanced stage of lung cancer, the patient refused further therapy. He passed away 3 weeks after first diagnosis of the adenocarcinoma.

    We reviewed the files of 80 successive patients with native and prosthetic valve endocarditis admitted to Riyadh Armed Forces Hospital. Neurolological complications (NC) occurred in 28 (35%) patients. The valves involved were mitral in 12 (43%), aortic in eight (29%), combined mitral and aortic lesions in six (21%) and others in two (7%). The common causative organisms were Streptococci in 12 (43%), Staphylococcus aureus and Staphylococcus epidermides, both occurring in four (14%). Compared to the 52 infective endocarditis patients with no neurological complications (NNC), the NC occurred more frequently in male patients, those with aortic valve lesion, those with atrial fibrillation, those with delayed therapy and those with causative organisms being Streptococci or Staphylococci. Eleven patients died (39%), 12 (43%) recovered with motor sequelae, six (21%) had seizure disorder and five (18%) had full recovery. The frequency of neurological complications and mortality is comparable to those reported in the literature: however, the frequency was higher in our patients. (author)

    Inflammation-associated lymphangiogenesis (IAL) has been identified as part of several acute and chronic inflammation. Sparse data exist on lymphatics during endocarditis. Fifty-two patients with surgically resected valves were included. Endocarditis was present in 18 aortic and 10 mitral valves. Controls consisted of 15 degenerative aortic and 9 degenerative mitral valves. There were 22 males with endocarditis and 17 males in controls. The mean age was 58 (SD 15) years with endocarditis vs. 62 (SD 13) years for controls. Lymphatics were detected by podoplanin antibody immunohistochemistry and morphometrical analysis was performed. The lymphatic density in endocarditis was 833 (SD 529) vessels/mm(2) (range 0-1707) as compared with 39 (SD 60) vessels/mm(2) (range 0-250) in controls (p=0.000). In endocarditis, the mean lymphatic size was 153 (SD 372) μm(2) ranging from 1 to 2034μm(2), whereas it was 30 (SD 29) μm(2), with maximum 90μm(2) and minimum 2μm(2) in controls (p=0.000). IAL is increased in valves with endocarditis as compared with controls. Lymphatics in heart valves may provide a novel means for treatment strategies against endocarditis.

    Full Text Available Objetivo: estudiar las características clínicas, epidemiológicas y microbiológicas, así como el tratamiento médico quirúrgico de los pacientes ingresados con el diagnóstico de endocarditis infecciosa, con el propósito de profundizar en su estudio y contribuir a un mejor tratamiento a estos pacientes. Métodos: se estudiaron 24 pacientes procedentes de todo el país, egresados con el diagnóstico de endocarditis infecciosa. Los datos fueron recogidos de las historias clínicas procedentes del archivo del Hospital "William Soler", y de la base de datos del servicio de cirugía del cardiocentro. Se determinó la frecuencia de las diferentes manifestaciones de la endocarditis infecciosa según: grupos etarios, factores de riesgo, y los datos clínicos, de laboratorio y microbiológicos más frecuentes. Además, se determinó la toma valvular predominante, la etiología y su respuesta a los antibióticos. Resultados: el grupo de edad más afectado fue entre 5 y 18 años; la cardiopatía previa fue el factor de riesgo predominante; los síntomas y signos más frecuentes fueron la fiebre, la anorexia y la pérdida de peso. La insuficiencia cardiaca y el embolismo pulmonar fueron complicaciones frecuentes. La mayoría de los pacientes tuvo una eritrosedimentación acelerada, y la cuarta parte de los casos presentaron hemocultivos negativos. Las válvulas aórtica y mitral resultaron las más afectadas, y el curso clínico que predominó fue el subagudo. En casi la mitad de los pacientes la infección tuvo un origen nosocomial. Los antimicrobianos más utilizados fueron la amikacina, la vancomicina y la ceftriaxona. Conclusiones: la endocarditis infecciosa es poco frecuente en nuestra institución, ocurre más a menudo en relación con las cardiopatías congénitas.

    Infective endocarditis in children remains a clinical challenge. Here, we review the impact of the updated 2015 American Heart Association and European Society of Cardiology guidelines on management as well as the significance of the new predisposing factors, diagnostic and treatment options, and the impact of the 2007-2008 change in prophylaxis recommendations. The new 2015 infective endocarditis guidelines introduced the endocarditis team, added the new imaging modalities of computer tomography and PET-computer tomography into the diagnostic criteria and endorsed the concept of safety of relatively early surgical treatment. The impact of the restriction of infective endocarditis prophylaxis since the 2007-2008 American Heart Association and National Institute for Health and Care Excellence recommendations is uncertain, with some studies showing no change and other more recent studies showing increased incidence. The difficulties in adjusting for varying confounding factors are discussed. The relative proportion of the device-related infective endocarditis is increasing. Special attention is paid to relatively high incidence of percutaneous pulmonary valve implantation-related infective endocarditis with low proportion of positive echo signs, disproportionate shift in causative agents, and unusual complication of acute obstruction. The significance of incomplete neoendothelialization on the risk of infective endocarditis on intracardiac devices is also discussed. The impact of changes in the infective endocarditis prophylaxis recommendations in pediatric patients is still uncertain. The device-related infective endocarditis has increasing importance, with the incidence on transcatheter implanted bovine jugular vein pulmonary valves being relatively high. The use of novel imaging, laboratory diagnostic techniques, and relatively early surgery in particular circumstances is important for management of paediatric infective endocarditis.

    This is a case report of an adult who presented with apparent culture negative endocarditis (CNE) thought to be marantic endocarditis due to a B-cell lymphoproliferative disorder. This was a most perplexing case and was eventually diagnosed as subacute bacterial endocarditis (SBE) due to a rare slow growing organism. Against the diagnosis of SBE was the lack of fever, hepatomegaly, peripheral manifestations and microscopic hematuria. Also, against a diagnosis of SBE was another explanation for the patient's abnormal findings, e.g., elevated ferritin levels, elevated α1/α2 globulins on SPEP, an elevated alkaline phosphatase, flow cytometry showing B-lymphocytes expressing CD5, and a bone lesion in the right iliac. Findings compatible with both SBE and marantic endocarditis due to a B-cell lymphoproliferative disorder included an elevated ESR, and splenomegaly. Blood cultures eventually became positive during hospitalization. We report a case of native aortic valve (AV) subacute bacterial endocarditis (SBE) due to Aerococcus christensenii mimicking marantic endocarditis due to a B-cell lymphoproliferative disorder. To the best of our knowledge, this is the first reported case of native AV SBE due to A. christensenii presenting as marantic endocarditis. Copyright © 2014 Elsevier Inc. All rights reserved.

    Endocarditis may precede or complicate bacterial meningitis, but the incidence and impact of endocarditis in bacterial meningitis are unknown. We assessed the incidence and clinical characteristics of patients with meningitis and endocarditis from a nationwide cohort study of adults with community-acquired bacterial meningitis in the Netherlands from 2006 to 2012. Endocarditis was identified in 24 of 1025 episodes (2%) of bacterial meningitis. Cultures yielded Streptococcus pneumoniae in 13 patients, Staphylococcus aureus in 8 patients, and Streptococcus agalactiae, Streptococcus pyogenes, and Streptococcus salivarius in 1 patient each. Clues leading to the diagnosis of endocarditis were cardiac murmurs, persistent or recurrent fever, a history of heart valve disease, and S aureus as the causative pathogen of bacterial meningitis. Treatment consisted of prolonged antibiotic therapy in all patients and surgical valve replacement in 10 patients (42%). Two patients were treated with oral anticoagulants, and both developed life-threatening intracerebral hemorrhage. Systemic (70%) and neurological (54%) complications occurred frequently, leading to a high proportion of patients with unfavorable outcome (63%). Seven of 24 patients (29%) with meningitis and endocarditis died. Endocarditis is an uncommon coexisting condition in bacterial meningitis but is associated with a high rate of unfavorable outcome.

    Primary mural endocarditis is an extremely rare infection in which nonvalvular endocardial involvement is seen without any cardiac structural abnormalities such as ventricular septal defects. The rapid and precise diagnosis of this disease remains challenging. We present 2 cases (67- and 47-year-old male patients) of pathologically confirmed primary mural endocarditis that could have been detected by initial transthoracic echocardiography in the emergency department. Transthoracic echocardiography and transesophageal echocardiography play critical roles in the early recognition and confirmation of primary mural endocarditis. © 2017 by the American Institute of Ultrasound in Medicine.

    2010-03-18

    Aorto-bifemoral bypass (AFB) is commonly performed to treat aorto-iliac disease and a durable long-term outcome is achieved. Most studies documenting beneficial outcomes after AFB have been limited to mortality and morbidity rates, costs and length of hospital stay (LOS). Few studies have examined the dependency of patients and how their perception of their own health changes after surgery. The aim of the present study was to evaluate outcome after AFB and to study its determinants. This retrospective study was carried out in the multidisciplinary Post-Anaesthesia Care Unit (PACU) with five intensive care beds. Out of 1597 intensive care patients admitted to the PACU, 75 were submitted to infrarenal AFB and admitted to these intensive care unit (ICU) beds over 2 years. Preoperative characteristics and outcome were evaluated by comparing occlusive disease with aneurysmatic disease patients. Six months after discharge, the patients were contacted to complete a Short Form-36 questionnaire (SF-36) and to have their dependency in Activities of Daily Living (ADL) evaluated. Patient's characteristics and postoperative follow-up data were compared using Mann-Whitney U test, t test for independent groups, chi-square or Fisher's exact test. Patient preoperative characteristics were evaluated for associations with mortality using a multiple logistic regression analysis. The mortality rate was 12% at six months. Multivariate analysis identified congestive heart disease and APACHE II as independent determinants for mortality. Patients submitted to AFB for occlusive disease had worse SF-36 scores in role physical and general health perception. Patients submitted to AFB had worse SF-36 scores for all domains than a comparable urban population and had similar scores to other PACU patients. Sixty-six percent and 23% of patients were dependent in at least one activity in instrumental and personal ADL, respectively, but 64% reported having better general health. This study shows that

    2001-01-01

    Full Text Available Erysipelothrix rhusiopathiae is known to cause infections in humans following exposure to decaying organic matter or animals colonized with the organism, such as swine and fish. Invasive infections with this organism are unusual and are manifested primarily as infective endocarditis. The present report is believed to be the first to report a case of E rhusiopathiae endocarditis and presumptive osteomyelitis. E rhusiopathiae appears to have intrinsic resistance to vancomycin. Because vancomycin is often used empirically for the treatment of endocarditis, rapid differentiation of E rhusiopathiae> from other Gram-positive organisms is critical. In patients with endocarditis caused by a Gram-positive bacillus and epidemiological risk factors for E rhusiopathiae exposure, empirical treatment with vancomycin should be reconsidered.

    Objective: To investigate the feature and value of echocardiography for diagnosing infective endocarditis. Methods: The shape, size, echogenicity, distribution of vegetations and valvular injury of the heart were observed in 30 patients with infective endocarditis. Results: The vegetations were located in the aortic valves (10 cases), bicuspid valves (5), tricuspid valve (1), pulmonary valve (2), main pulmonary artery with patent ductus arteriosus (2), and right ventricle with ventricular septal defect (2). The size of vegetation ranged from 2 to 27 mm and the echogenicity of vegetations was low to high. The location, size, shape and amount of vegetations observed on echocardiography correlated well with the operative findings. Echocardiography also demonstrated underlying heart disease and abnormal hemodynamics induced by infective endocarditis. Conclusion: Echocardiography can determine the location, size, shape, amount of vegetation and concomitant cardiac disease in patients with infective endocarditis. It play an important role in treatment and prognosis. (authors)

    Little is known about the magnitude of the association between infective endocarditis and cancer, and about the natural history of cancer patients with concomitant diagnosis of infective endocarditis. We used the SEER-Medicare linked database to identify individuals aged 65 years or more diagnosed with colorectal, lung, breast, or prostate cancer, and without any cancer diagnosis (5% random Medicare sample from SEER areas) between 1992 and 2009. We identified infective endocarditis from the ICD-9 diagnosis of each admission recorded in the Medpar file and its incidence rate 90 days around cancer diagnosis. We also estimated the overall survival and CRC-specific survival after a concomitant diagnosis of infective endocarditis. The peri-diagnostic incidence of infective endocarditis was 19.8 cases per 100,000 person-months for CRC, 5.7 cases per 100,000 person-months for lung cancer, 1.9 cases per 100,000 person-months for breast cancer, 4.1 cases per 100,000 person-months for prostate cancer and 2.4 cases per 100,000 person-months for individuals without cancer. Two-year overall survival was 46.4% (95% CI 39.5, 54.5%) for stage I-III CRC patients with concomitant endocarditis and 73.1% (95 % CI 72.9, 73.3%) for those without it. In this elderly population, the incidence of infective endocarditis around CRC diagnosis was substantially higher than around the diagnosis of lung, breast and prostate cancers. A concomitant diagnosis of infective endocarditis in patients with CRC diagnosis is associated with shorter survival.

    An autopsy case of membranous glomerulonephritis associated with enterococcal endocarditis was reported. Although enterococcal antigen was not identified in glomerular deposits, the eluate from the patient's renal tissue was shown to specifically recombine with cells of the enterococcus isolated from his own ante mortem blood. Hypocomplementemia, circulating immune complexes and antienterococcal antibodies were also observed. These findings suggest that enterococcus-related immune complexes played a role in the pathogenesis of glomerulonephritis associated with enterococcal endocarditis in this patient.

    Full Text Available La endocarditis infecciosa es una enfermedad de baja incidencia que en las últimas décadas mostró modificaciones respecto de su presentación, posibilidad diagnóstica y tratamiento. A pesar de estos avances, la mortalidad hospitalaria sigue siendo muy elevada. Nuestro objetivo fue analizar las características de los pacientes con endocarditis infecciosa activa y su relación con la mortalidad hospitalaria a lo largo de 16 años. Se realizó un registro prospectivo entre 1994 y 2010 de pacientes ingresados con endocarditis. Se analizaron características clínicas, evolución y tratamiento y se registraron los eventos intrahospitalarios. Ingresaron 152 pacientes, 64.5% varones, edad 45 ± 16 años, las causas más frecuentes de cardiopatía de base fueron: congénita 32 (21% y reumática 20 (13.2%. Los motivos de internación fueron síndrome febril 116 (76.3% e insuficiencia cardíaca 61 (40.1%. Se identificó el agente infeccioso en 106 (69.7% de los casos, el más frecuente fue Streptococcus viridans. El ecocardiograma mostró vegetaciones en 123 (80.9% de los pacientes y 88 (57.8% presentaron complicaciones durante su internación, siendo la más frecuente la insuficiencia cardíaca. Se indicó tratamiento quirúrgico en 96 (63.1% de los casos, fundamentalmente por insuficiencia cardíaca en 66. La mortalidad hospitalaria global fue 46 (30.2%. El desarrollo de complicaciones en la internación, la indicación de cirugía y la presencia de insuficiencia cardíaca refractaria al tratamiento fueron predictores independientes de mortalidad hospitalaria, mientras que la presencia de vegetaciones resultó un predictor independiente de mejor supervivencia. La identificación temprana de estos predictores descriptos podría ayudar a mejorar los resultados.

    Infective endocarditis is associated with not only cardiac complications but also neurologic, renal, musculoskeletal, and systemic complications related to the infection, such as embolization, metastatic infection, and mycotic aneurysm. We report three cases (the first patient is Chinese and the other two are Koreans) of complicated infective endocarditis; two of the cases were associated with a mycotic aneurysm, and one case was associated with a splenic abscess. One case of a patient with prosthetic valve endocarditis was complicated by intracerebral hemorrhage caused by mycotic aneurysm rupture. A second case of a patient with right-sided valve endocarditis associated with a central catheter was complicated by an abdominal aortic mycotic aneurysm. The third patient had a splenic infarction and abscess associated with infected cardiac thrombi. Complicated infective endocarditis is rare and is associated with cardiac, neurologic, renal, musculoskeletal, and systemic complications related to infection, such as embolization, metastatic infection, and mycotic aneurysm. Infective endocarditis caused by Staphylococcus aureus is more frequently associated with complications. Because the mortality rate increases when complications develop, aggressive antibiotic therapy and surgery, combined with specific treatments for the complications, are necessary.

    Abstract Among culture-negative endocarditis in the United States, Bartonella species are the most common cause, with Bartonella henselae and Bartonella quintana comprising the majority of cases. Kidney manifestations, particularly glomerulonephritis, are common sequelae of infectious endocarditis, with nearly half of all Bartonella patients demonstrating renal involvement. Although a pauci-immune pattern is a frequent finding in infectious endocarditis–associated glomerulonephritis, it is rarely reported in Bartonella endocarditis. Anti–neutrophil cytoplasmic antibody (ANCA) positivity can be seen with many pathogens causing endocarditis and has been previously reported with Bartonella species. In addition, ANCA-associated vasculitis can also present with renal and cardiac involvement, including noninfectious valvular vegetations and pauci-immune glomerulonephritis. Given the overlap in their clinical presentation, it is difficult to differentiate between Bartonella endocarditis and ANCA-associated vasculitis but imperative to do so to guide management decisions. We present a case of ANCA-positive Bartonella endocarditis with associated pauci-immune glomerulonephritis that was successfully treated with medical management alone. PMID:27885316

    Infective endocarditis (IE) caused by anaerobic bacteria is a rare and poorly characterized disease. Most data reported in the literature are from case reports [1-3]. Therefore, we assessed the situation of anaerobic IE (AIE) in Spain using the database of the Spanish Collaboration on Endocarditis (GAMES). We performed a prospective study from 2008 to 2016 in 26 Spanish centers. We included 2491 consecutive cases of definite IE (Duke criteria). Anaerobic bacteria caused 22 cases (0.9%) of definite IE. Median age was 66 years (IQR, 56-73), and 19 (86.4%) patients were men. Most patients (14 [63.6%]) had prosthetic valve IE and all episodes were left-sided: aortic valves, 12 (54.5%); and mitral valves, 8 (36.4%). The most common pathogens were Propionibacterium acnes (14 [63.6%]), Lactobacillus spp (3 [13.63%]), and Clostridium spp. (2 [9.0%]), and the infection was mainly odontogenic. Fifteen of the 22 patients (68.2%) underwent cardiac surgery. Mortality was 18.2% during admission and 5.5% after 1 year of follow-up. When patients with AIE were compared with the rest of the cohort, we found that although those with AIE had a similar age and Charlson comorbidity index, they were more likely to have community-acquired IE (86.4% vs. 60.9%, p = 0.01), have undergone cardiac surgery (68.2% vs 48.7% p = 0.06), and have had lower mortality rates during admission (18.2% vs. 27.3%). IE due to anaerobic bacteria is an uncommon disease that affects mainly prosthetic valves and frequently requires surgery. Otherwise, there are no major differences between AIE and IE caused by other microorganisms. Copyright © 2017 Elsevier Ltd. All rights reserved.

  14. Aggregatibacter aphrophilus pacemaker endocarditis: a case report.

    2014-12-08

    Aggregatibacter bacteria are a rare cause of endocarditis in adults. They are part of a group of organisms known as HACEK--Haemophilus, Aggregatibacter, Cardiobacter, Eikenella, and Kingella. Among these organisms, several Haemophilus species have been reclassified under the genus Aggregatibacter. Very few cases of Aggregatibacter endocarditis in patients with pacemaker devices have been reported. We present here what we believe to be the first case of Aggregatibacter aphrophilus pacemaker endocarditis. A 62-year-old African American male with a medical history significant for dual-chamber pacemaker placement in 1996 for complete heart block with subsequent lead manipulation in 2007, presented to his primary care doctor with fever, chills, night sweats, fatigue, and ten-pound weight loss over a four-month period. Physical examination revealed a new murmur and jugular venous distension which prompted initiation of antibiotics for suspicion of endocarditis. Both sets of initial blood cultures were positive for A. aphrophilus. Transesophageal echocardiogram revealed vegetations on the tricuspid valve and the right ventricular pacemaker lead (Figure 1). This case highlights the importance of identifying rare causes of endocarditis and recognizing that treatment may not differ from the standard treatment for typical presentations. The patient received intravenous ceftriaxone for his endocarditis for a total of six weeks. Upon device removal, temporary jugular venous pacing wires were placed. After two weeks of antibiotic treatment and no clinical deterioration, a new permanent pacemaker was placed and the patient was discharged home. This is the first case of A. aphrophilus endocarditis in a patient with a permanent pacemaker. Our patient had no obvious risk factors other than poor dentition and a history of repeated pacemaker lead manipulation. This suggests that valvulopathies secondary to repeated lead manipulation can be clinically significant factors in morbidity

    Physiological flows in rigid diseased arterial flow phantoms emulating an abdominal aortic aneurysm (AAA) under rest conditions with aorto-iliac bifurcation and iliac stenosis are examined in vitro through 2D PIV measurements. Flow characteristics are first established in the model resembling a symmetric AAA with a straight outlet tube. The influence of aorto-iliac bifurcation and iliac stenosis on AAA flow dynamics is then explored through a comparison of the nature of flow patterns, vorticity evolution, vortex core trajectory and hemodynamic factors against the reference configuration. Specifically, wall shear stress and oscillatory shear index in the bulge portion of the models are of interest. The results of this investigation indicate overall phenomenological similarity in AAA flow patterns across the models. The pattern is characterized by a central jet and wall-bounded vortices whose strength increases during the deceleration phase as it moves forward. The central jet impacts the wall of AAA at its distal end. In the presence of an aorto-iliac bifurcation as well as iliac stenosis, the flow patterns show diminished strength, expanse and speed of propagation of the primary vortices. The positions of the instantaneous vortex cores, determined using the Q-function, correlate with flow separation in the bulge, flow resistance due to a bifurcation, and the break in symmetry introduced by a stenosis in one of the legs of the model. Time-averaged WSS in a healthy aorta is around 0.70 N m-2 and is lowered to the range ±0.2 N m-2 in the presence of the downstream bifurcation with a stenosed common iliac artery. The consequence of changes in the flow pattern within the aneurysm on disease progression is discussed.

    Full Text Available Effect of abdominal aorto-venocaval shunt (AVS on the automaticity of the pulmonary-vein myocardium was studied in the rat. Spontaneous electrical activity was observed in one third of the isolated pulmonary-vein preparations from the AVS rats, but scarcely in those from sham-operated rats; the activity was induced by tertiapin and suppressed by carbachol or chelation of intracellular Ca2+. The evoked action potentials in AVS rats had less negative resting membrane potential and longer action potential duration than those in sham-operated rats. These results suggest that the automaticity of the rat pulmonary-vein myocardium is manifested under chronic volume overload.

    Full Text Available Objetivo: estudiar las características clínicas, epidemiológicas y microbiológicas, así como el tratamiento médico quirúrgico de los pacientes ingresados con el diagnóstico de endocarditis infecciosa, con el propósito de profundizar en su estudio y contribuir a un mejor tratamiento a estos pacientes. Métodos: se estudiaron 24 pacientes procedentes de todo el país, egresados con el diagnóstico de endocarditis infecciosa. Los datos fueron recogidos de las historias clínicas procedentes del archivo del Hospital "William Soler", y de la base de datos del servicio de cirugía del cardiocentro. Se determinó la frecuencia de las diferentes manifestaciones de la endocarditis infecciosa según: grupos etarios, factores de riesgo, y los datos clínicos, de laboratorio y microbiológicos más frecuentes. Además, se determinó la toma valvular predominante, la etiología y su respuesta a los antibióticos. Resultados: el grupo de edad más afectado fue entre 5 y 18 años; la cardiopatía previa fue el factor de riesgo predominante; los síntomas y signos más frecuentes fueron la fiebre, la anorexia y la pérdida de peso. La insuficiencia cardiaca y el embolismo pulmonar fueron complicaciones frecuentes. La mayoría de los pacientes tuvo una eritrosedimentación acelerada, y la cuarta parte de los casos presentaron hemocultivos negativos. Las válvulas aórtica y mitral resultaron las más afectadas, y el curso clínico que predominó fue el subagudo. En casi la mitad de los pacientes la infección tuvo un origen nosocomial. Los antimicrobianos más utilizados fueron la amikacina, la vancomicina y la ceftriaxona. Conclusiones: la endocarditis infecciosa es poco frecuente en nuestra institución, ocurre más a menudo en relación con las cardiopatías congénitas. Los hechos clínicos más constantes fueron la fiebre y el antecedente de cardiopatía previa.

    Aorto-esophageal fistula (AEF) is a rare and lethal entity, and the difficulty of making diagnosis of AEF is well-known. As promising results in the short-term effectiveness of thoracic endovascular aortic repair (TEVAR) promote its usage, the occurrence of AEF after TEVAR (post-TEVAR AEF) increases as one of the major complications. Therefore, we provide a review concerning the management strategy of post-TEVAR AEF. Although its representative symptom was reported as the triad of mid-thoracic pain and sentinel hematemesis followed by massive hematemesis, the symptom-free interval between sentinel hemorrhage and massive exsanguination is unpredictable. However, the physiological condition represents a surgical contraindication. Accordingly, early diagnosis is important, but either CT or esophago-gastro-duodenoscopy rarely depicts a typical image. The formation of post-TEVAR AEF might be associated with the infection of micro-organisms, which is uncontrollable with anti-biotic administration. The current first-line strategy is combination therapy as follows, (1) to control bleeding by TEVAR in the urgent phase, and (2) radical debridement and aortic/esophageal re-construction in the semi-urgent phase. In view of the high mortality and morbidity rate, it is proposed that the choice in treatment strategies might be affected by patient`s condition, size of the wall defects and the etiology of AEF. Practically, we should keep in mind the importance of making an early diagnosis and, once a suspicious symptom has occurred in a patient with a history of TEVAR, the existence of post-TEVAR AEF should be suspected. A prospective registry together with more developed technologies will be needed to establish a future strategy.

    Infective endocarditis (IE) is an infection that develops on the endothelial surface of the heart. Endocarditis is a major problem for the clinicians despite of the developments in diagnostic, surgical, and medical treatment methods. In this study, we aimed to evaluate symptoms, laboratory findings, treatment options, and clinical endpoint of the patients who were diagnosed with IE in a tertiary healthcare organization according to the literature data. Between January 2006 and March 2013, 80 IE patients who were diagnosed and treated in accordance with modified Duke criteria were enrolled in the study. Demographic features, symptoms, and laboratory and echocardiographic findings were recorded after reviewing the patient files. The mean age of the patients was 51.3 ± 16.0, and IE was more common in men (n = 56; 70%). Of 41 patients who had positive blood cultures, 20 patients had Staphylococcus spp. (48.7%) and 8 patients had Streptococcus spp. (19.5%). Brucella spp. was isolated from 5 patients (12.2%). While 48.7% (n = 39) of the patients had cardiac complications, 22 patients (27.5%) had embolic complication. Hospital mortality was observed in 20 patients (15%). In our patients, endocarditis was seen at a young age, and staphylococci were the most frequently isolated microorganism from blood culture. There were more patients with Brucella endocarditis compared to the general population. Complications are frequently seen in the course of endocarditis, and they cause problems for the clinicians during follow ups due to the high mortality rate of IE.

    Acute bacterial endocarditis continues to be a condition with high morbidity. Although the majority of patients are treated by high-dose antibiotics, a high-risk patient group requires surgical intervention, which is the subject of this article. From 1972 to 1991, 3,820 patients underwent heart valve replacement at the Brigham and Women's Hospital, Boston. Of this group, 158 patients underwent surgery for acute bacterial endocarditis: 109 had native valve endocarditis (NVE), and 49 had prosthetic valve endocarditis (PVE). There were 108 men and 50 women with a mean age of 49 years (range, 16-79 years); 64% were New York Heart Association functional class IV before surgery, and 12% of the group had a history of intravenous drug abuse. In both NVE and PVE groups, Streptococcus was the predominant infecting agent. Uncontrolled sepsis, progressive congestive failure, peripheral emboli, and echocardiographically demonstrated vegetations were the most common indications for surgery. Eighty-five percent of patients had a single-valve procedure, 15% had a multivalve procedure, and 34 patients had other associated major cardiac procedures. The operative mortality was 6% in NVE and 22% in PVE. Long-term survival at 10 years was 66% for NVE and 29% for PVE. Freedom from recurrent endocarditis at 10 years was 85% for NVE and 82% for PVE. The main factors associated with decreased survival overall were PVE and nonstreptococcal infection. The morbidity and mortality after surgical treatment of acute endocarditis depend on the site, the severity, and the subject infected. Early aggressive surgical intervention is indicated to optimize surgical results, especially in patients with nonstreptococcal infection or PVE.

    Although Escherichia coli is among the most common causes of Gram-negative bacteraemia, infectious endocarditis (IE) due to this pathogen is rare. A 67-y-old male without a previous medical history presented with a new mitral regurgitation murmur and persisting E. coli bacteraemia in spite of broad......-spectrum intravenous antibiotics. Transthoracic and transoesophageal echocardiography revealed a severe mitral endocarditis. E. coli DNA was identified from the mitral valve and the vegetation, and no other pathogen was found. The case was further complicated by spondylodiscitis and bilateral endophthalmitis. Extra...

    Summary Heart failure is one of the leading causes of death in developed nations. End stage heart failure often requires cardiac transplantation for survival. The left ventricular assist device (LVAD) has been one of the biggest evolvements in heart failure management often serving as bridge to transplant or destination therapy in advanced heart failure. Like any other medical device, LVAD is associated with complications with infections being reported in many patients. Endocarditis developing secondary to the placement of LVAD is not a frequent, serious and difficult to treat condition with high morbidity and mortality. Currently, there are few retrospective studies and case reports reporting the same. In our review, we found the most common cause of endocarditis in LVAD was due to bacteria. Both bacterial and fungal endocarditis were associated with high morbidity and mortality. In this review we will be discussing the risk factors, organisms involved, diagnostic tests, management strategies, complications, and outcomes in patients who developed endocarditis secondary to LVAD placement.

    Full Text Available Both endocarditis and Bartonella infections are neglected public health problems, especially in rural Asia. Bartonella endocarditis has been described from wealthier countries in Asia, Japan, Korea, Thailand and India but there are no reports from poorer countries, such as the Lao PDR (Laos, probably because people have neglected to look.We conducted a retrospective (2006-2012, and subsequent prospective study (2012-2013, at Mahosot Hospital, Vientiane, Laos, through liaison between the microbiology laboratory and the wards. Patients aged >1 year admitted with definite or possible endocarditis according to modified Duke criteria were included. In view of the strong suspicion of infective endocarditis, acute and convalescent sera from 30 patients with culture negative endocarditis were tested for antibodies to Brucella melitensis, Mycoplasma pneumoniae, Bartonella quintana, B. henselae, Coxiella burnetii and Legionella pneumophila. Western blot analysis using Bartonella species antigens enabled us to describe the first two Lao patients with known Bartonella henselae endocarditis.We argue that it is likely that Bartonella endocarditis is neglected and more widespread than appreciated, as there are few laboratories in Asia able to make the diagnosis. Considering the high prevalence of rheumatic heart disease in Asia, there is remarkably little evidence on the bacterial etiology of endocarditis. Most evidence is derived from wealthy countries and investigation of the aetiology and optimal management of endocarditis in low income countries has been neglected. Interest in Bartonella as neglected pathogens is emerging, and improved methods for the rapid diagnosis of Bartonella endocarditis are needed, as it is likely that proven Bartonella endocarditis can be treated with simpler and less expensive regimens than "conventional" endocarditis and multicenter trials to optimize treatment are required. More understanding is needed on the risk factors for

    Full Text Available Infective endocarditis (IE is an infection of the endocardium that involves valves and adjacent mural endocardium or a septal defect. Local complications include severe valvular insufficiency, which may lead to intractable congestive heart failure and myocardial abscesses. If left untreated, IE is generally fatal. Diagnosing IE can be straightforward in patients with the typical oslerian manifestations such as bacteremia, evidence of active valvulitis, peripheral emboli, and immunologic vascular phenomena. In the acute course, however, the classic peripheral stigmata may be few or absent, particularly among intravenous drug abuse (IVDA patients in whom IE is often due to a S. aureus infection of right-sided heart valves. We present a complicated case of a very aggressive native aortic valve MSSA (methicillin sensitive Staphylococcus aureus IE in a young adult male with a past medical history of bicuspid aortic valve and IV drug abuse. His clinical course was complicated by aortic valve destruction and development of third-degree AV block, as well as an aorto-left atrial fistula requiring emergent operation for AV replacement and patch repair. The patient required two reoperations for recurrent endocarditis and its complications.

Entre las causas más importantes de muerte por tabaquismo están el cáncer pulmonar y la enfermedad pulmonar obstructiva crónica (EPOC. La erradicación del tabaquismo es la mejor estrategia de prevención de estas enfermedades. La segunda estrategia es la detección precoz de ellas. Sin embargo la EPOC está sub diagnosticada en todo el mundo. No está claro si la solución es hacer más espirometrías en población de riesgo. Es posible que otros métodos diagnósticos como la tomografía axial computada de tórax (TAC y la difusión pulmonar, puedan mejorar la capacidad de diagnóstico precoz de esta enfermedad. El cáncer pulmonar es el más mortal de los cánceres. El diagnóstico en etapas tempranas mejora significativamente su pronóstico. Hay varios estudios en curso que evalúan el beneficio de hacer pesquisa de cáncer pulmonar con TAC.

    2015-02-01

    Full Text Available La presencia de hipertensión pulmonar (HP en el embarazo es poco frecuente y conlleva un alto riesgo para madres e hijos. Existe escasa bibliografía relacionada al diagnóstico de la misma luego del parto. Se describen tres pacientes a quienes se diagnostica HP luego de cursar sus embarazos y partos libres de eventos. A pesar de desconocerse las causas, son varios los mecanismos propuestos, como la hipercoagulabilidad, la hipoxia placentaria o la embolia de líquido amniótico. Resulta difícil definir si la HP diagnosticada en el puerperio, corresponde a una HP en período asintomático que fue desenmascarada por el estrés fisiológico del parto o es una condición de reciente comienzo. A pesar de la falta de datos que avalen la ausencia de HP previa al embarazo en nuestras tres casos, el curso libre de eventos en sus embarazos, sin síntomas y con partos normales, indican que no padecían esta enfermedad hasta el momento del parto, y que la desarrollaron posteriormente. De haberla padecido antes se hubieran presentado síntomas previos al parto o en el puerperio inmediato, ya que las demandas hemodinámicas deterioran gravemente a un ventrículo con poca reserva.

    2017-02-01

    The history of infective endocarditis (IE) is a good example of medical progress. Initially incurable, endocarditis, when diagnosed, was synonym of death. After significant diagnostic progress, thanks to Osler's contribution especially, the first surgeries and antibacterial drugs obtained very few successful cures. We had to wait until Flamming's discovery to observe frequent cures thanks to antibiotics. Surgery manages to push possibilities of cure a bit further. However, paravalvular extensions, described since the first surgical case of IE, was a real technical matter. Thus, the second half of 20th century was devoted to overcoming this surgical challenge. In this historical review, we describe the story of severe IE, especially with paravalvular involvement, by highlighting major progress - clinical and surgical, that allows its current management.

    Full Text Available Behcet's disease is a systemic vasculitis of unknown aetiology with cardiac involvement as well as damage to other organs. Whether the sterile valvular inflammation which occurs in this autoimmune disease predisposes to bacterial adhesion and infective endocarditis is not yet established. We present the case of a patient with Behcet disease in which transthoracic echocardiography showed mobile masses on the aortic, tricuspid, and mitral valves, leading to multivalvular infective endocarditis diagnosis, possibly in the context of valvular inflammation. The case presented in this article confirms observation of other studies, namely that ultrasonography plays an important role in the diagnosis and evaluation of rheumatic diseases and permits optimal management in daily practice.

En este contexto, resulta muy acertada la publicación del artículo “Algunas variables clínico-epidemiológicas de la tuberculosis pulmonar. Puerto Padre, 2008-2012”, que salió en el Vol.38 No.6.01 del mes de junio de 2013 de la Revista Electrónica Dr. Zoilo E. Marinello Vidaurreta; tanto por el significado social que reviste la divulgación de este tema, como por el propio resultado de la investigación realizada. La historia de la tuberculosis es un tema apasionante. En pocas enfermedades es posible documentar su estrecha relación con la historia de la propia humanidad como en la que nos ocupa. Existen evidencias paleológicas de tuberculosis vertebral en momias egipcias que datan aproximadamente del año 2400 a.C. La tuberculosis se ha conocido a través de la historia, con los nombres de: tisis, consunción, escrófula, mal de Pott, plaga blanca y mal del rey.1 En el artículo se plantea como conclusión que la tendencia de la tuberculosis en el quinquenio de estudio es estacionaria, pero en los últimos cuatro años tiende al ascenso. En los casos diagnosticados de tuberculosis en este quinquenio más de dos tercios correspondieron al sexo masculino y mayores de 45 años, las ocupaciones que más prevalecieron fueron recluso, desocupado, ama de casa y jubilado. Los factores de riesgo que más se relacionaron fueron el albergamiento prolongado en instituciones cerradas, el alcoholismo, y la edad mayor de 65 años; la forma clínica de mayor incidencia en casi la totalidad de los pacientes fue la pulmonar y, dentro de ella, los casos con baciloscopia positiva.

    Imipenem, a potent new beta-lactam antibiotic, which is bactericidal against most pathogenic bacteria, and cilastatin, a dehydropeptidase inhibitor combined with imipenem to prevent the metabolism of imipenem in the kidney, were evaluated in the treatment of bacterial endocarditis. Seventeen patients, including 14 who used intravenous drugs, were treated with imipenem/cilastatin in a dose of 500 mg each infused over 30 minutes every six hours. The mean duration of treatment was 29 days with a range of 21 to 56 days. Causative bacteria were Staphylococcus aureus in 10 patients, S. aureus plus group B Streptococcus in one, viridans group Streptococcus in two, Neisseria subflava, Eikenella corrodens, and group G Streptococcus in one patient, and Staphylococcus epidermidis, Hemophilus aphrophilus, and Enterobacter aerogenes in one patient each. The minimal bactericidal concentration of imipenem against 16 of 18 isolates tested was 0.04 micrograms/ml, 1 microgram/ml against H. aphrophilus, and 0.4 micrograms/ml against E. aerogenes. The site of infection was the right side of the heart in 11 patients, the left side in five, and both sides in one. The mean number of days to defervescence was 9.7. All patients were cured, and none required cardiac surgery. Adverse effects were few and interrupted treatment occurred in only one patient who had acute dyspnea during an infusion on Day 26 of therapy. Imipenem/cilastatin appears to be a relatively safe and highly effective treatment of staphylococcal endocarditis in intravenous drug users; too few patients with endocarditis caused by other bacteria were treated to allow a firm statement about efficacy in non-staphylococcal endocarditis.

    A 32-year-old male who had infective endocarditis complained of photophobia and blurred vision in both eyes. Biomicroscopic examination and fundus examination revealed anterior chamber reaction, vitritis, optic disc swelling, and Roth spots. He was diagnosed with bilateral nongranulomatous uveitis and treated with topical steroid eye drops and posterior sub-Tenon injection of triamcinolone. His visual symptoms were resolved within 1 week, and inflammation resolved within 4 weeks after treatment.

A pesar de la notable frecuencia de las complicaciones neurológicas en la endocarditis infecciosa, dadas especialmente por enfermedad cerebrovascular y neuroinfecciones, aun existen controversias acerca de algunos aspectos diagnósticos y terapéuticos, en parte por la poca evidencia disponible, las cuales se discuten a continuación, a partir de una serie de casos atendidos en la Fundación Cardiovascular de Colombia.Neurological complications of acute infective endocarditis are described in 20%-40% of cases, representing an important predictive factor of morbidity, mortality, sequels and disability. Acute endocarditis is characterized by a wide clinical spectrum due to its complex physiopathology that involves inflammatory, immune, infectious and embolic phenomena. Despite the remarkable frequency of neurological complications in the infective endocarditis especially by cerebrovascular disease and neuroinfections, there are still some controversies about some diagnostic and therapeutic aspects, partly because of the little evidence available. This paper describes a number of cases seen in the Fundación Cardiovascular de Colombia and discusses some aspects related with the diagnosis and treatment of the neurological complications of acute endocarditis.

    Full Text Available AbstractBackground. Infectious endocarditis of the tricuspid valve is rare in non-intravenous drug users and patients without central venous devices. The most frequent causative agents are staphylococci, rarely other bacteria.Methods. We describe a case of a 57-year-old patient without history of drug abuse that was admitted to our hospital because of fever with chills, dry cough, loss of appetite and wasting lasting for a few months. He had a venous ulcer on the right foot and interdigital inflammation on both feet. Eikenella corrodens was isolated from blood cultures. Transthoracic echocardiography showed a large vegetation on the anterior leaflet of tricuspid valve. CT scan oh the thorax showed probable septic emboli. The patient was treated conservatively with prolonged double antibiotic regimen. During the treatment there were no further complications.Conclusions. In our patients a rare form of tricuspid valve endocarditis was confirmed, caused by Eikenella corrodens. The possibility of infectious endocarditis should always be considered in patients with prolonged fever, especially when a possible causative agent is isolated from blood cultures.

    Full Text Available El manejo del paciente con hipertensión pulmonar es complejo y requiere de un equipo interdisciplinario. Es trascendental que los programas de rehabilitación cuenten con neumólogo, fisioterapeutas entrenados, psicólogos, profesionales en trabajo social, nutrición y enfermería. Para el ingreso al programa los pacientes deben contar con manejo farmacológico óptimo y prueba de ejercicio cardiopulmonar integrada o prueba de caminata de seis minutos para determinar la condición basal, las causas de limitación al ejercicio y la intensidad del ejercicio, y prever riesgos. Se indican al menos dos a tres sesiones a la semana supervisadas durante 10 a 12 semanas para lograr mejoría en cuanto a capacidad de ejercicio, calidad de vida y niveles de actividad física. Se puede hacer entrenamiento en ambiente hospitalario, ambulatorio o mixto aunque siempre con comienzo en un ámbito supervisado y con el equipo de monitorización necesario. En cuanto al riesgo, en pacientes con hipertensión pulmonar clase funcional IV, la frecuencia de eventos adversos no fue mayor al compararse con pacientes en clase funcional II y III; los efectos del entrenamiento en estos pacientes son similares a los obtenidos en aquellos con mejor clase funcional con necesidad de reducir la intensidad del ejercicio para que sea tolerado y seguro. Es vital educar tanto al paciente como a su cuidador en cuanto a la enfermedad, y adicionalmente brindar soporte psicosocial y nutricional.

    Full Text Available We present a case of severe tracheobronchial compression from a complex aorto-subclavian aneurysm in a patient with Turner′s syndrome undergoing open surgical repair. Significant airway compression is a challenging situation and requires careful preoperative preparation, maintenance of spontaneous breathing when possible, and consideration of having an alternative source of oxygenation and circulation established prior to induction of general anesthesia. Cardiopulmonary monitoring is essential for safe general anesthesia and diagnosis of unexpected intraoperative events.

    Purpose: The purpose of this study was to investigate correlations between the aorto-popliteal bolus transit speed and aortic and popliteal bolus transit time in order to evaluate the possibility for prediction of bolus transit speed by single test injection technique. Materials and methods: Approval was obtained from our institutional review board for this study, which included 42 patients, from all of whom written informed consent was obtained. Low-dose serial CT scanning after injection of 12 ml contrast material (300 mg/ml) at a rate of 3 ml/s followed by saline flush was performed twice, first at the level of the upper abdomen and second at the level of the knee joint. The times needed to reach peak enhancement of the upper abdominal aorta (T-aorta) and bilateral popliteal arteries (T-popliteal) were obtained, and aorto-popliteal bolus transit speeds between the abdominal aorta and popliteal arteries were calculated. ABI was recorded for the bilateral feet. The Pearson's product-moment correlation coefficient was used to investigate the correlation between the bolus transit speed and T-aorta, T-popliteal, ABI, and patient age. Result: The respective correlation coefficients for bolus transit speed on the one hand and T-aorta, T-popliteal, ABI, patient age on the other were -0.50, -0.84, 0.36, and -0.52. Conclusion: The time to peak enhancement for popliteal arteries showed the strongest correlation with aorto-popliteal bolus transit speeds, and was considered to be the most accurate predictor for aorto-popliteal bolus transit speeds.

    Crucial to the management of staphylococcal bacteremia is an accurate evaluation of associated endocarditis, which has both therapeutic and prognostic implications. Because the clinical presentation of endocarditis can be nonspecific, the judicious use of echocardiography is important in distinguishing patients at high risk of developing endocarditis. In the presence of high-risk clinical features, an early transesophageal echocardiogram is warranted without prior transthoracic echocardiography. The purpose of this study was to investigate the clinical risk factors for staphylococcal infective endocarditis that might warrant earlier transesophageal echocardiography and to describe the incidence of endocarditis in cases of methicillin-resistant and methicillin-sensitive Staphylococcus aureus bacteremia. A retrospective case-control study was conducted by means of chart review of 91 patients consecutively admitted to a community hospital from January 2009 through January 2013. Clinical risk factors of patients with staphylococcal bacteremia were compared with risk factors of patients who had definite diagnoses of infective endocarditis. There were 69 patients with bacteremia alone (76%) and 22 patients with endocarditis (24%), as verified by echocardiography. Univariate analysis showed that diabetes mellitus ( P =0.024), the presence of an automatic implantable cardioverter-defibrillator/pacemaker ( P =0.006) or a prosthetic heart valve ( P =0.003), and recent hospitalization ( P =0.048) were significantly associated with developing infective endocarditis in patients with S. aureus bacteremia. The incidence of methicillin-resistant and methicillin-sensitive S. aureus bacteremia was similar in the bacteremia and infective-endocarditis groups ( P =0.437). In conclusion, identified high-risk clinical factors in the presence of bacteremia can suggest infective endocarditis. Early evaluation with transesophageal echocardiography might well be warranted.

    Minimal access mitral valve surgery (MVS) has already proved to be feasible and effective with low perioperative mortality and excellent long-term outcomes. However, experience in more complex valve diseases such as infective endocarditis (IE) still remains limited. The aim of this retrospective study was to evaluate early and long-term results of minimal access MVS for IE. Data were entered into a dedicated database. Analysis was performed retrospectively for the 8-year period between January 2007 and April 2015. During the study period, 35 consecutive patients underwent minimal access MVS for IE at our department. Twenty-four had diagnosis of native MV endocarditis (68.6%) and 11 of mitral prosthesis endocarditis (31.4%).Thirty patients underwent early MVS (85.7%), and 5 patients were operated after the completion of antibiotic treatment (14.3%). Seven patients underwent MV repair (20%), 17 patients underwent MV replacement (48.6%), and 11 patients underwent mitral prosthesis replacement (31.4%). Thirty-day mortality was 11.4% (4 patients). No neurological or vascular complications were reported. One patient underwent reoperation for prosthesis IE relapse after 37 days. Overall actuarial survival rate at 1 and 5 years was 83%; freedom from MV reoperation and/or recurrence of IE at 1 and 5 years was 97%. Minimally invasive MVS for IE is feasible and associated with good early and long-term results. Preoperative accurate patient selection and transoesophageal echocardiography evaluation is mandatory for surgical planning. © The Author 2017.

    The epidemiology of infective endocarditis (IE) appears to be related to changes in the management of children with congenital heart disease (CHD) and the virtual disappearance of rheumatic heart disease. To better understand these changes, we divide the history into: I. The pre-surgical era, II. The early years of CHD surgical intervention, correlated with introduction of antibiotics, III. The modern era of cardiac interventions. Microbiologic changes include an early predominance of viridans streptococci and an overtaking by staphylococci. Additionally, there have been advances in imaging that allow earlier detection of IE and a reduction in IE-related mortality. Copyright © 2015 Elsevier Inc. All rights reserved.

    There is strong evidence that fat accumulating in non-adipose sites, "ectopic fat", is associated with cardiovascular disease (CVD), including vascular calcification. Most previous studies of this association have assessed only a single ectopic fat depot. Therefore, our aim was to assess the association of total, regional, and ectopic fat with abdominal aorto-illiac calcification (AAC) and coronary artery calcification (CAC) in 798 African ancestry men. Participants (mean age 62) were from the Tobago Bone Health Study cohort. Adiposity was assessed via clinical examination, dual x-ray absorptiometry, and computed tomography (CT). Ectopic fat depots included: abdominal visceral adipose tissue (VAT), liver attenuation, and calf intermuscular adipose tissue (IMAT). Vascular calcification was assessed by CT and quantified as present versus absent. Associations were tested using multiple logistic regression adjusted for traditional cardiovascular risk factors. Models of ectopic fat were additionally adjusted for total body fat and standing height. All adiposity measures, except VAT, were associated with AAC. Lower liver attenuation or greater calf IMAT was associated with 1.2-1.3-fold increased odds of AAC (p fat measure was associated with CAC. Greater adiposity in the skeletal muscle and liver, but not in the visceral compartment, was associated with increased odds of AAC in African ancestry men. These results highlight the potential importance of both quantity and location of adiposity accumulation throughout the body. Copyright © 2017 Elsevier B.V. All rights reserved.

    Infective endocarditis is an important cause of morbidity and mortality in patients receiving haemodialysis for established renal failure. We carried out a prospective audit of patients developing infective endocarditis in a single renal unit. From 1 January 2000 to 31 December 2013, we collected data on all cases of endocarditis occurring in patients receiving haemodialysis at Monklands Hospital, Airdrie. Twenty-nine patients developed endocarditis during our audit period. Twenty-three (79.3%) of the patients had pre-existing cardiac valve abnormalities such as regurgitation or calcification. Staphylococcus aureus was the most common microorganism cultured from the blood of 22 patients (75.9%). MRSA bacteraemia was identified in eight of these patients and all eight patients died during that first presentation. Different strategies were introduced within the unit during the audit period aiming to reduce the rate of bacteraemia. Since 2011, a successful strategy has been introduced under the auspices of the Scottish Patient Safety Programme. This led to our Staph aureus bacteraemia rate related to non-tunnelled venous catheters going from an average of 15 days between episodes to having had no episodes between 2 December 2011 and the end of the study period (760 days). This also appears to have had a positive impact on reducing the rate of endocarditis. Infective endocarditis remains a devastating consequence of bacteraemia in patients receiving haemodialysis. An effective strategy aimed at reducing the rate of bacteraemia appears to have a similar effect on the rate of endocarditis. © The Author(s) 2016.

    Endocarditis is a cardiovascular disease caused by the inflammation of the inner tissues of the heart, the endocardium, usually of the valves. Bacteraemia is essential in the development of endocarditis, and there are some findings that the main pathogens of endocarditis are viridans group streptococci: Streptococcus oralis, Streptococcus sanguinis, and Enterococcus faecalis. There is strong evidence that endocarditis bacteria are present in the tonsillar microbiota, so that tonsillar infection is associated with an increased risk of endocarditis. The aim of this manuscript is to investigate the presence of the main pathogens of endocarditis in tonsillar microbiota of an Afghan population group. A sample of 80 tonsil swabs were analyzed by quantitative real time PCR to detect endocarditis pathogens and an estimation of the total bacterial load. The median bacterial load in PCR reaction was 1.4x106 (interquartile range 4,7x105 - 2,9x106). Three species, S. Oralis, S. Sanguinis, and E. Faecalis were found in large amounts in all specimens. On the other hand, S. Mitis was never detected. The S. Aureus was found in 3 samples with a prevalence of 0.04 (C.I. 0.01-0.10). The S. Mutans was found in 33 samples with a prevalence of 0.41 (C.I. 0.31-0.52). Endocarditis bacteria has been found into the tonsillar microbiota, so there is sufficient evidence to justify that the oral cavity is a reservoir of endocarditis bacteria that can have a significant impact on the cardiovascular function.

    Full Text Available Endocarditis due to brucellosis is considered a rare occurrence involving native, congenital and prosthetic valves. The diagnosis needs high degree of suspicion in culture negative endocarditis especially in those with history of exposure to farm animals. A positive culture in a susceptible patient confirms the diagnosis with 91% sensitivity. An early diagnosis and prompt treatment with appropriate antibiotics can restore the valve structural integrity with minimal damage. Here we present a series of five cases of culture proven Brucella endocarditis (four native valves, one prosthetic valve and this report discusses the diagnostic and management issues involved.

    Infective endocarditis is a severe infection arising in the lining of the chambers of the heart with a high mortality rate.Many dental procedures cause bacteraemia and it was believed that this may lead to bacterial endocarditis (BE) in a few people. Guidelines in many countries have recommended that prior to invasive dental procedures antibiotics are administered to people at high risk of endocarditis. However, recent guidance by the National Institute for Health and Care Excellence (NICE) in England and Wales has recommended that antibiotics are not required. To determine whether prophylactic antibiotic administration, compared to no such administration or placebo, before invasive dental procedures in people at risk or at high risk of bacterial endocarditis influences mortality, serious illness or the incidence of endocarditis. The following electronic databases were searched: the Cochrane Oral Health Group's Trials Register (to 21 January 2013), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 12), MEDLINE via OVID (1946 to 21 January 2013) and EMBASE via OVID (1980 to 21 January 2013). We searched for ongoing trials in the US National Institutes of Health Trials Register (http://clinicaltrials.gov) and the metaRegister of Controlled Trials (http://www.controlled-trials.com/mrct/). No restrictions were placed on the language or date of publication when searching the electronic databases. Due to the low incidence of BE it was anticipated that few if any trials would be located. For this reason, cohort and case-control studies were included where suitably matched control or comparison groups had been studied. The intervention was the administration of antibiotic, compared to no such administration, before a dental procedure in people with an increased risk of BE. Cohort studies would need to follow those individuals at increased risk and assess outcomes following any invasive dental procedures, grouping by whether

  14. Infective Endocarditis in Children — New Approach in Antimicrobial Prophylaxis

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available Infective endocarditis (IE is an infection of the endocardium and/or heart valves with the formation of a thrombus and secondary damage of the involved tissue, with significant mortality and severe complications. The prevention of bacterial endocarditis is of great controversy. Antimicrobial prophylaxis is usable in the prevention of endocarditis by killing bacteria before or after their extension to the damaged endocardium. No human studies offer strong evidence to support the efficacy of antibiotic prophylaxis so far, thus it could be potentially dangerous. Therefore, the European Society of Cardiology (ESC may need to reconsider and update the previous guidelines with the proposal of reducing the prophylactic approach of IE. The 2015 Task Force recommends prophylaxis for highest risk patients undergoing highest risk procedures, focused on prevention rather than prophylaxis of IE, especially in nosocomial endocarditis.

    It was possible to induce bacterial endocarditis in opossums with single intravenous injections of Streptococcus viridans or Staphylococcus aureus. Fiftyeight percent of those animals given Streptococcus viridans developed bacterial endocarditis in which most of the lesions were on the left side of the heart. The experimentally induced streptococcal disease was similar to that which may occur spontaneously in opossums, both with respect to the distribution and structure of the vegetations. Single injections of Staphylococcus aureus resulted in endocarditis in 100% of the test animals. These lesions differed from those due to streptococci by having a relatively high frequency of right- as well as left-sided valvular disease and by being somewhat smaller than those due to streptococci.Endocarditis could not be successfully induced with injection of three different fungi.

    Pseudoaneurysm is an uncommon sequela of infective endocarditis. We treated a 44-year-old man who had an active case of group B streptococcal infective endocarditis of the aortic valve despite no evidence of valvular dysfunction or vegetation on his initial transesophageal echocardiogram. After completing 6 weeks of intravenous antibiotic therapy, the patient developed a sinus of Valsalva pseudoaneurysm and severe aortic regurgitation caused by partial detachment of the left coronary cusp. We used a pericardial patch to close the pseudoaneurysm and repair the coronary cusp. This case shows the importance of routine clinical follow-up evaluation in infective endocarditis, even after completion of antibiotic therapy. Late sequelae associated with infective endocarditis or its therapy include recurrent infection, heart failure caused by valvular dysfunction (albeit delayed), and antibiotic toxicity such as aminoglycoside-induced nephropathy and vestibular toxicity.

    The diagnosis of infective endocarditis is often delayed in clinical practice. Timely diagnosis and rapid antibiotic treatment is important. Higher age of patients, new risk factors, and increasing use of intravascular prosthetic materials resulted in changes in microbial spectrum. Nowadays, nonspecific symptoms, critically ill patients, and immunocompromised patients require a high level of diagnostic expertise.The new guidelines from the European Society of Cardiology provide various diagnostic algorithms and recommendations for antibiotic treatment. The new guidelines also recommend the formation of an endocarditis team with various medical disciplines, including a cardiac surgeon, to improve treatment because in half of all endocarditis patients, antibiotic therapy alone does not result in successful management of the infection. If complications occur, early surgical treatment should be performed.In this overview, diagnostic strategies and therapeutic approaches for the treatment of infectious endocarditis according to the current guidelines and aspects of surgical treatment are provided.

    2016-01-01

    Full Text Available Endocarditis associated with dialysis catheter is a disease that must be suspected in every patient with hemodialysis who develops fever. Multiple valve disease is a severe complication of endocarditis that needs to be managed in a different way. There is very limited data for treatment and every case must be considered individually. We present a patient with this complication and describe the medical treatment and surgical management. We report the case of a 15-year-old patient with acute renal failure that develops trivalvular endocarditis after the hemodialysis catheter was placed, with multiple positive blood culture for Staphylococcus aureus. Transesophageal echocardiography was done and aortic and tricuspid valvular vegetations and mitral insufficiency were reported. Patient was successfully treated by surgery on the three valves, including aortic valve replacement. There is limited data about the appropriate treatment for multiple valvular endocarditis; it is important to consider this complication in the setting of hemodialysis patients that develop endocarditis and, despite the appropriate treatment, have a torpid evolution. In countries where endovenous drug abuse is uncommon, right sided endocarditis is commonly associated with vascular catheters. Aggressive surgical management should be the treatment of choice in these kinds of patients.

    Infective endocarditis in a patient after kidney transplantation is a serious infective complication which increases the risk of loss of the graft and also the mortality of patients. The most important predisposing factor is the immunosuppressive therapy - mainly induction immunosuppression.Material and case description: 250 patients underwent kidney transplantation throughout the period of 12 years in the Transplant Center Martin. This set of patients included 5 patients (2 %) after heart valve replacement. We present the case of a patient after kidney transplantation with development of endocarditis of the bioprosthesis of the aortic valve one month after successful kidney transplantation. Diagnostics of endocarditis by standard procedures (examination by transthoracic echocardiogram, transesophageal echocardiography, hemocultures) was unsuccessful. We rarely diagnosed endocarditis only by PET-CT examination with a consequent change of the antibiotic treatment and successful managing of this post-transplant complication. Endocarditis after kidney transplantation is a serious complication which significantly worsens the mortality of patients. The risk of development of infective endocarditis after transplantation is also increased by induction, mainly by antithymocyte globulin. Diagnostics only by PET-CT examination is rare; however, in this case it fundamentally changed the approach to the patient and led to a successful treatment.

    To analyze the characteristics and outcome of infective endocarditis (IE) according to the time interval between IE first symptoms and diagnosis. Among the IE cases of a French population-based epidemiological survey, patients having early-diagnosed IE (diagnosis of IE within 1 month of first symptoms) were compared with those having late-diagnosed IE (diagnosis of IE more than 1 month after first symptoms). Among the 486 definite-IE, 124 (25%) had late-diagnosed IE whereas others had early-diagnosed IE. Early-diagnosed IE were independently associated with female gender (OR = 1.8; 95% CI [1.0-3.0]), prosthetic valve (OR= 2.6; 95% CI [1.4-5.0]) and staphylococci as causative pathogen (OR = 3.7; 95% CI [2.2-6.2]). Cardiac surgery theoretical indication rates were not different between early and late-diagnosed IE (56.3% vs 58.9%), whereas valve surgery performance was lower in early-diagnosed IE (41% vs 53%; p = .03). In-hospital mortality rates were higher in early-diagnosed IE than in late-diagnosed IE (25.1% vs 16.1%; p endocarditis, which time interval between first symptoms and diagnosis was less than one month, were mainly due to Staphylococcus aureus in France. Staphylococcus aureus infective endocarditis were associated with septic shock, transient ischemic attack or stroke and higher mortality rates than infective endocarditis due to other bacteria or infective endocarditis, which time interval between first symptoms and diagnosis was more than one month. Infective endocarditis, which time interval between first symptoms and diagnosis was more than one month, were accounting for one quarter of all infective endocarditis in our study and were associated with vertebral osteomyelitis and a higher rate of cardiac surgery performed for hemodynamic indication than other infective endocarditis.

    The introduction of the Duke criteria and transesophageal echocardiography has improved early recognition of infective endocarditis but patients are still at high risk for severe morbidity or death. Whether an exclusively antibiotic regimen is superior to surgical intervention is subject to ongoing debate. Current guidelines indicate when surgery is the preferred treatment, but decisions are often based on physician preferences. Surgery has shown to decrease the risk of short-term mortality in patients who present with specific symptoms or microorganisms; nevertheless even then it often remains unclear when surgery should be performed. In this review we i) systematically reviewed the current literature comparing medical to surgical therapy to evaluate if surgery is the preferred option, ii) performed a meta-analysis of studies reporting propensity matched analyses, and iii), briefly summarized the current indications for surgery.

    Non-bacterial thrombotic endocarditis (NBTE) and, in particular, infective endocarditis (IE), are serious and potentially life-threatening diseases. An increasingly important agent of human IE is Staphylococcus aureus, which typically causes an acute endocarditis with high mortality. The study aim was to evaluate the pig as a model for non-bacterial as well as S. aureus-associated endocarditis, as these models would have several advantages compared to other laboratory animal models. Fourteen animals underwent surgery with placement of a plastic catheter in the left side of the heart. Six of the pigs did not receive a bacterial inoculation and were used to study the development of NBTE. The remaining eight pigs were inoculated intravenously once or twice with S. aureus, 10(5)-10(7) cfu/kg body weight. Two bacterial strains were used: S54F9 (porcine) and NCTC8325-4 (human). Clinical examination, echocardiography and bacterial blood cultures were used to diagnose and monitor the development of endocarditis. Animals were euthanized at between two and 15 days after catheter placement, and tissue samples were collected for bacteriology and histopathology. Pigs inoculated with 10(7) cfu/kg of S. aureus strain S54F9 developed clinical, echocardiographic and pathologic signs of IE. All other pigs, except one, developed NBTE. Serial blood cultures withdrawn after inoculation were positive in animals with IE, and negative in all other animals. S. aureus endocarditis was successfully induced in pigs with an indwelling cardiac catheter after intravenous inoculation of 10(7) cfu/kg of S. aureus strain S54F9. The model simulates typical pathological, clinical and diagnostic features seen in the human disease. Furthermore, NBTE was induced in all but one of the pigs without IE. Thus, the pig model can be used in future studies of the pathogenesis, diagnosis and therapy of NBTE and S. aureus endocarditis.

    A small sub-group of patients with hypoplastic left heart syndrome (HLHS) have normal-sized ascending aorta and arch. An alternative to the Norwood I procedure in these patients is the creation of an aorto-pulmonary (AP) window with a distal pulmonary artery band (PAB). We reviewed our experience with this technique and compared outcomes to the Norwood procedure for HLHS. All patients treated for HLHS in a single institution between 1992 and 2005 were analysed. This identified 13 patients treated with AP window and PAB compared to 333 patients undergoing stage I Norwood procedure. An unrestrictive AP window was created and the main PA was banded. Patient records and echocardiograms were analysed. Median follow-up was 10 (IQR 0-655) days and 100% complete. There were seven early deaths (54%) in the AP window group and two conversions to Norwood circulation. This was a significantly worse outcome than for the Norwood procedure over the same period, which had an early mortality of 29% (p=0.03). Kaplan-Meier actuarial analysis demonstrated a continued survival benefit of the Norwood group at 6 months (p=0.0005). Deaths were due to either low cardiac output syndrome (n=4) or sudden unheralded arrest (n=3). This occurred despite aortic cross-clamp and circulatory arrest times being significantly lower in the AP window group compared to the Norwood group (35+/-27 vs 55+/-16 min, p<0.01 and 16+/-29 vs 55+/-20 min, p<0.01, respectively). No differences in arterial saturations or systolic blood pressure existed between the groups, but diastolic blood pressure was significantly lower in the AP window group at 27+/-10 mmHg compared to 42+/-8 mmHg in the Norwood group (p=0.01) with evidence of flow reversal in the descending aorta. Differences in diastolic blood pressure between groups were abolished after conversion to stage II. Despite favourable anatomy and shorter ischaemic times, the AP window/PAB technique has a poor outcome compared to the Norwood procedure for HLHS. Low

    Ventricular function was measured by radionuclide angiography during rest and exercise in 27 patients before and after aorto-coronary bypass grafting (AC bypass). The patients were divided in three groups: 6 patients in complete revascularisation (group A), 8 patients in surgical complete revascularisation (group B), and 13 patients in incomplete revascularisation (group C). Heart rate increased by exercise from 58 +- 5 bpm to 87 +- 5 bpm, from 60 +- 5 bpm to 90 +- 15 bpm, and from 61 +- 8 bpm to 84 +- 7 bpm before AC bypass, and increased from 81 +- 7 bpm to 116 +- 11 bpm, from 86 +- 13 bpm to 114 +- 12 bpm, and from 80 +- 11 bpm to 106 +- 13 bpm after AC bypass in group A, B and C, respecitively. EF decreased by exercise from 61 +- 7 % to 58 +- 12 %, from 53 +- 10 % to 49 +- 7 %, and from 54 +- 8 % to 52 +- 8 % before AC bypass, and increased by exercise from 66 +- 7 % to 77 +- 6 %, from 49 +- 11 % to 56 +- 13 %, and from 54 +- 8 % to 59 +- 10 % after AC bypass in group A,FB and C, respectively. dV/dt(Vmax/sec) increased by exercise from 4.0 +- 1.0 to 4.4 +- 1.0, from 2.5 +- 1.0 to 3.4 +- 1.5 and from 3.5 +- 0.5 to 3.4 +- 0.6 before AC bypass, and increased from 3.9 +- 0.5 to 6.2 +- 0.7, from 3.5 +- 0.9 to 5.0 +- 0.7, and from 3.6 +- 1.0 to 5.4 +- 1.5 after AC bypass in group A,B and C, respectively. In conclusion, left ventricular performance during exercise was significantly increased after AC bypass in all patients. However, the rate of increase in left ventricular performance during exercise after AC bypass was more significant in the group of complete revascularisation than in the group of others. Serial application of radionuclide angiography to patients after AC bypass appears promising in evaluating the long-term effects of operation on ventricular function. (author)

  2. Isolated pulmonic valve endocarditis presenting as neck pain

    Full Text Available We discuss a unique case of a 52-year-old man with no history of intravenous drug use or dental procedures who presented with neck pain, 2 weeks of fevers, chills, night sweats, cough, and dyspnea found to have isolated pulmonic valve (PV endocarditis. The patient did not have an associated murmur, which is commonly seen in right-sided infectious endocarditis. A transthoracic echocardiogram showed a thickened PV leaflet, with subsequent transesophageal echocardiogram showing a PV mass. Speciation of blood cultures revealed Streptococcus oralis. In right-sided infective endocarditis, usually the tricuspid valve is involved; however, in our case the tricuspid valve was free of any mass or vegetation. The patient did meet Duke criteria and was thus started on long-term intravenous antibiotics for infectious endocarditis. The patient's symptoms quickly improved with antibiotics. A careful history and evaluating the patient's risk factors are key in earlier detection of infective endocarditis (IE. Because of early detection and a high index of suspicion, the patient had no further complications and did not require any surgery. In conclusion, clinical suspicion of right-sided IE should be high in patients who present with persistent fevers and pulmonary symptoms in order to reduce the risk of complications, and to improve outcomes.

    Fungal prosthetic valve endocarditis is an extremely severe form of infective endocarditis, with poor prognosis and high mortality despite treatment. Candida albicans is the most common etiological agent for this rare but increasingly frequent condition. We present a case of fungal prosthetic valve endocarditis due to C. albicans following aortic and pulmonary valve replacement in a 38-year-old woman with a history of surgically corrected tetralogy of Fallot, prior infective endocarditis and acute renal failure with need for catheter-based hemodialysis. Antifungal therapy with liposomal amphotericin B was initiated prior to cardiac surgery, in which the bioprostheses were replaced by homografts, providing greater resistance to recurrent infection. During hospitalization, a mycotic aneurysm was diagnosed following an episode of acute arterial ischemia, requiring two vascular surgical interventions. Despite the complications, the patient's outcome was good and she was discharged on suppressive antifungal therapy with oral fluconazole for at least a year. The reported case illustrates multiple risk factors for fungal endocarditis, as well as complications and predictors of poor prognosis, demonstrating its complexity.

    The activity of garenoxacin was compared to that of levofloxacin or penicillin in a rabbit model of Streptococcus mitis group (penicillin MIC, 0.125 microg/ml) and Streptococcus sanguinis group (penicillin MIC, 0.25 microg/ml) endocarditis. Garenoxacin and levofloxacin had MICs of 0.125 and 0.5 microg/ml, respectively, for both study isolates. Rabbits with catheter-induced aortic valve endocarditis were given no treatment, penicillin at 1.2x10(6) IU/8 h intramuscularly, garenoxacin at 20 mg/kg of body weight/12 h intravenously, or levofloxacin at 40 mg/kg/12 h intravenously. For both isolates tested, garenoxacin area under the curve (AUC)/MIC and maximum concentration of drug in serum (Cmax)/MIC ratios were 368 and 91, respectively. Rabbits were sacrificed after 3 days of treatment; cardiac valve vegetations were aseptically removed and quantitatively cultured. For S. mitis group experimental endocarditis, all studied antimicrobial agents were more active than no treatment (PS. sanguinis group endocarditis, no studied antimicrobial agents were more active than no treatment. We conclude that AUC/MIC and Cmax/MIC ratios may not predict activity of some quinolones in experimental viridans group endocarditis and that garenoxacin and levofloxacin may not be ideal choices for serious infections caused by some quinolone-susceptible viridans group streptococci.

    Sensitivity and specificity of the modified Duke criteria for native valve endocarditis are both suboptimal, at approximately 80%. Diagnostic accuracy for intracardiac prosthetic material-related infection is even lower. Non-invasive imaging modalities could potentially improve diagnosis of infective endocarditis; however, their diagnostic value is unclear. We did a systematic literature review to critically appraise the evidence for the diagnostic performance of these imaging modalities, according to PRISMA and GRADE criteria. We searched PubMed, Embase, and Cochrane databases. 31 studies were included that presented original data on the performance of electrocardiogram (ECG)-gated multidetector CT angiography (MDCTA), ECG-gated MRI, 18 F-fluorodeoxyglucose ( 18 F-FDG) PET/CT, and leucocyte scintigraphy in diagnosis of native valve endocarditis, intracardiac prosthetic material-related infection, and extracardiac foci in adults. We consistently found positive albeit weak evidence for the diagnostic benefit of 18 F-FDG PET/CT and MDCTA. We conclude that additional imaging techniques should be considered if infective endocarditis is suspected. We propose an evidence-based diagnostic work-up for infective endocarditis including these non-invasive techniques. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Diagnosing infective endocarditis and its complications can be difficult because of the nonspecific symptoms. We reviewed findings of intracranial abnormalities on magnetic resonance imaging (MRI) in 14 patients with neurological complications and herein discuss the overall intracranial MRI findings. We retrospectively reviewed patients with infective endocarditis from August 2004 to August 2006. Brain MRI, the causative bacteria, and abnormal neurological symptoms were reviewed for 14 patients with neurological complications. Of the 14 patients, 13 showed intracranial abnormalities on MRI. Embolization was seen in 10 patients, hemorrhage in 3, abscess formation in 3, and encephalitis in 2. Hyperintense lesions with a central hypointense area on T2-weighted and/or T2*-weighted imaging (Bull's-eye-like lesion) were seen in four patients. A combination of these intracranial abnormalities was observed in 6 patients. The MRI findings associated with infective endocarditis are wide-ranging: embolization, hemorrhage, meningitis, cerebritis, abscess, the bull's-eye-like lesion. Clinicians should consider the possibility of infective endocarditis in patients with unknown fever and neurological abnormality. Brain MRI should be promptly performed for those patients, and T2*-weighted imaging is recommended for an early diagnosis of infective endocarditis. (author)

    The presentation of infective endocarditis (IE) has changed over time and its diagnosis remains difficult since it relies on the conjunction of a number of criteria which have their own limitations. The Duke classification allows for a standardized approach and is now recognized as the reference method for the diagnosis of IE. The diagnostic value of the different criteria of the Duke classification can be improved by the use of transoesophageal echocardiography for the detection of endocardial involvement and the use of non-cardiac imaging for the detection of embolic events. The number of cases of IE without identified causative microorganism can be reduced due to serological analyses and broad-range polymerase chain reaction on explanted valves. Radionuclide imaging techniques are useful when the diagnosis of IE remains uncertain. [18F]FDG PET/CT can be used for the diagnosis of cardiac infection and for the detection of embolic events or metastatic infection, keeping in mind the possibility of false positive diagnosis due to its high sensitivity. Radiolabelled-leukocytes scintigraphy is more specific than [18F]FDG PET/CT and can differentiate between septic and sterile vegetations. Diagnostic flowcharts are proposed to combine the Duke classification and recent imaging techniques for the diagnostic workup of IE.

    Full Text Available We report a case of a 74-year-old female, with a mitral heart valve, who presented with pain and blurred vision in the right eye for 2 days. Her visual acuity was light perception (LP in the right eye and 20/40 in the left eye. Slit lamp examination showed corneal edema and hypopyon, and a view of the right fundus was impossible. Echography showed vitreous condensation. One day after presentation, the patient developed acute lung edema requiring hospitalization, so she was not submitted to vitreous tap and intravitreal treatment. The cardiac and systemic evaluations revealed a mitral endocarditis secondary to Enterococcus faecalis. The patient improved systemically with treatment with gentamicin, vancomycin, and linezolid. Her visual acuity remained as no LP, and her intraocular pressure (IOP has been controlled with brimonidine bid despite developing a total cataract with 360° posterior synechia. A cardiac source for endogenous endophthalmitis should be considered in the presence of a prosthetic cardiac valve. The treatment and followup must be made in cooperation with a cardiologist specialist, but the ophthalmologist can play a key role in the diagnosis.

  11. Extracardiac manifestations of infective endocarditis and their historical descriptions.

    In his landmark "Gulstonian Lectures on Malignant Endocarditis," published in 1885, William Osler commented, "Few diseases present greater difficulties in the way of diagnosis than malignant endocarditis, difficulties which in many cases are practically insurmountable." At that time, the fields of microbiology and blood cultures were in their infancy, and the diagnosis was made premortem in just half the patients with the condition. After Osler's report, extracardiac physical findings became essential clues to earlier diagnosis. Today, infective endocarditis is most commonly suggested from the history and often clinched by an echocardiogram and blood cultures. Although prized physical manifestations are much less frequent now, they still do occur and may be an invaluable clue that leads to earlier, more effective treatment. The investigators review these extracardiac findings along with their historical descriptions: splinter hemorrhages, emboli, Osler's nodes, Janeway and Bowman lesions of the eye, Roth spots, petechiae, and clubbing.

    Antineutrophil cytoplasmic antibodies (ANCA) associated with infective endocarditis are a rare disorder. The condition can mimic primary systemic vasculitis (i.e. granulomatosis with polyangiitis, microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis). Thus, a wrong diagnosis of valvular involvement related to primary systemic vasculitis can be made in patients exhibiting ANCA associated with infective endocarditis. Because treatment of both conditions is different, this wrong diagnosis will lead to dramatic consequences in these latter patients. This review reports the state of knowledge and proposes an algorithm to follow when confronted to a possible case of ANCA associated with infective endocarditis.

    Recurrence of infection is observed in a high proportion of patients who have had infective endocarditis in the past. The aim of our study was to evaluate the possible differences between the first and the recurrent episodes of endocarditis, as well as to assess the outcome and prognosis of patients with recurrent endocarditis. We reviewed a series of 13 episodes of recurrent endocarditis from among 196 cases of infective endocarditis involving non-drug-addict patients in two hospitals from 1987 to 2000. There were no differences between recurrent and first episodes of endocarditis according to age, sex, heart valve involved or causal microorganisms. Prosthetic valve endocarditis was more common in patients with recurrent endocarditis (86% versus 27%; p < 0.001). Although there were no differences in the rate of complications or early surgery, overall mortality was significantly higher in patients with recurrent endocarditis (53% versus 27%: p < 0.05). When early and late mortality were analysed separately, the differences did not achieve significance. Recurrent endocarditis was frequent in our series (7% of all cases). The features were similar to those of the first episode except for a higher rate of prosthetic valve endocarditis and a higher overall mortality.

    Guidelines for diagnosis of infective endocarditis are largely based upon epidemiological studies in referral hospitals. Referral bias, however, might impair the validity of guidelines in non-referral hospitals. Recent studies in non-referral care centres on infective endocarditis are sparse. We conducted a retrospective epidemiological study on infective endocarditis in a large non-referral hospital in a Belgian city (Kortrijk). The medical record system was searched for all cases tagged with a putative diagnosis of infective endocarditis in the period 2003-2010. The cases that fulfilled the modified Duke criteria for probable or definite infective endocarditis were included. Compared to referral centres, an older population with infective endocarditis, and fewer predisposing cardiac factors and catheter-related infective endocarditis is seen in our population. Our patients have fewer prosthetic valve endocarditis as well as fewer staphylococcal endocarditis. Our patients undergo less surgery, although mortality rate seems to be highly comparable with referral centres, with nosocomial infective endocarditis as an independent predictor of mortality. The present study suggests that characteristics of infective endocarditis as well as associative factors might differ among non-referral hospitals and referral hospitals.

    We investigated our surgical strategy and clinical results in patients from active infective endocarditis (AIE) complicated by paravalvular involvement to determine the risk factors of early and late death and reoperation. From October 1979 to December 2014, 955 patients underwent operations for AIE; among them 207 had AIE with paravalvular extension. The patients were a mean age of 59.9 ± 15.4 years, and 162 (78%) were male. Of these patients, 137 (66%) had isolated aortic valve endocarditis, and 138 (67%) had native valve endocarditis. Follow-up was 99% complete. The operative mortality of the cohort was 16% (n = 34). Abnormal communication, mechanical valve implantation, and renal failure were independent predictors of 30-day death. Survival at 1, 5, 10, and 15 years was 90.3% ± 2.3%, 62.4% ± 3.7%, 49.3% ± 4.1%, and 37.9% ± 4.4%, respectively. Streptococcus endocarditis (all species), complex annular repair, and preoperative heart failure were independent predictors of long-term death. A reoperation was required in 29 patients (14%). Streptococcus pneumoniae endocarditis was the only independent predictor of early reoperation (within 30 days after the operation or during the same hospitalization). Freedom from reoperation at 1, 5, 10, and 15 years was 91.9% ± 2.2%, 89.6% ± 2.6%, 89.6% ± 2.6%, and 87.0% ± 3.5%, respectively. Independent predictors of late reoperation were urgent/emergency operation, prosthetic valve endocarditis, and complex annular repair. AIE complicated by paravalvular involvement remains a surgical challenge. Valve replacement (particularly using bioprosthesis) associated with ad hoc reconstruction seems to be a reliable option and showed very encouraging results in this context.

    2018-03-01

    Full Text Available While typhoid fever is a common infection, Salmonella enterica serovar Typhi is a rare cause of endocarditis. We describe the case of a 20-year-old male who was treated for a primary episode of microbiologically-confirmed typhoid fever. He presented six weeks post-discharge with fever and lethargy. S. Typhi was again identified in blood cultures, and echocardiography identified a mitral valve lesion. Our case suggests that a relapse of typhoid should prompt further investigation for a deep-seated infection, including consideration of echocardiographic evaluation to rule out infective endocarditis.

    Infective endocarditis complicated by abscess formation and coronary artery compression is a rare clinical event with a high mortality rate, and diagnosis requires a heightened degree of suspicion. We present the clinical, angiographic, and echocardiographic features of a 73-year-old woman who presented with dyspnea and was found to have right coronary artery compression that was secondary to abscess formation resulting from diffuse infectious endocarditis. We discuss the patient's case and briefly review the relevant medical literature. To our knowledge, this is the first reported case of abscess formation involving a native aortic valve and the right coronary artery.

    Eleven patients with a clinical diagnosis of bacterial endocarditis underwent scintillation scanning of the precordial region 2--7 days after the intravenous administration of 3 mCi of gallium-67 citrate. Seven had positive scans, 3 of which were confirmed by postmortem imaging at autopsy. Serial images revealed the scans to be frequently negative at 48 hours and positive from 3 to 8 days following injection. Uptake was not seen in the region of the myocardium 48 hours or longer after the injection of 15 patients without endocarditis used as controls.

    Enterococci are common organisms associated with endocarditis, but infection by Enterococcus durans is very rare. To our knowledge, only 3 cases have been reported in the medical literature, and all 3 have involved native valves. Here we publish the first reported case (to our knowledge) of E. durans endocarditis in association with a bioprosthetic aortic valve. After the organism and its antibiotic susceptibility were identified, the 74-year-old male patient was treated successfully with teicoplanin and gentamicin, over a course of 6 weeks.

    Full Text Available Infective endocarditis is a life-threatening disease caused by a focus of infection within the heart. For clinicians and scientists, it has been a moving target that has an evolving microbiology and a changing patient demographic. In the absence of an extensive evidence base to guide clinical practice, controversies abound. Here, we review three main areas of uncertainty: first, in prevention of infective endocarditis, including the role of antibiotic prophylaxis and strategies to reduce health care-associated bacteraemia; second, in diagnosis, specifically the use of multimodality imaging; third, we discuss the optimal timing of surgical intervention and the challenges posed by increasing rates of cardiac device infection.

    Full Text Available A 48-year-old man presented to the Victoria General Hospital, Halifax, Nova Scotia in severe congestive heart failure. Echocardiographic studies revealed significant aortic valve insufficiency. Two anaerobic blood cultures performed two weeks apart were both positive for Actinomyces meyeri. The patient was treated with high dose intravenous penicillin. Three weeks after antibiotics were begun, he underwent aortic valve replacement. Intraoperative cultures were negative. Histopathological examination revealed findings in keeping with subacute bacterial endocarditis. The patient completed a six-week course of penicillin and was doing well three months after surgery. This is the first case of endocarditis attributable to A meyeri reported in the literature.

    Full Text Available La fibrosis pulmonar idiopática (FPI es una enfermedad que se caracteriza por presentar un compromiso pulmonar de tipo restrictivo, resultante de una reducción en la complacencia pulmonar secundaria a fibrosis difusa. En el enfisema, la pérdida de elasticidad pulmonar y el colapso de las vías aéreas periféricas generan obstrucción e hiperinflación. El efecto simultáneo que ambas enfermedades producen sobre la fisiología pulmonar no es del todo claro y se han descripto volúmenes pulmonares normales o casi normales. Presentamos 4 pacientes de sexo masculino de 64, 60, 73 y 70 años, con antecedentes de tabaquismo e historia de disnea progresiva, tres de ellos con grave limitación en su calidad de vida al momento de la consulta. En la tomografía de tórax de alta resolución todos los pacientes presentaban signos de enfermedad intersticial pulmonar avanzada, con cambios de tipo fibrótico con predominio basal y subpleural, que coexistían con enfisema centroacinar con predominio en lóbulos superiores. Uno de ellos tuvo confirmación diagnóstica de ambas condicioes por biopsia pulmonar a cielo abierto. En los cuatro pacientes la espirometría y volúmenes pulmonares fueron normales, pero tenían importante compromiso del intercambio gaseoso evaluado mediante el test de caminata de 6 minutos. Tres de los pacientes tenían hipertensión pulmonar grave diagnosticado por ecocardiograma. La presencia de volúmenes pulmonares normales no excluye un diagnóstico de fibrosis pulmonar idiopática en pacientes fumadores si coexisten evidencias tomográficas de enfisema. En estos pacientes el grado de compromiso funcional, determinado por la reducción de los volúmenes pulmonares, no debería ser considerado en la evaluación de la gravedad.Pulmonary function tests in idiopathic pulmonary fibrosis characteristically show a restrictive pattern, resulting from reduction of pulmonary compliance due to diffuse fibrosis.

    This study investigated the possible relationship between endocarditis and overall and individual cancer risk among study participants in Taiwan.We used data from the National Health Insurance program of Taiwan to conduct a population-based, observational, and retrospective cohort study. The case group consisted of 14,534 patients who were diagnosed with endocarditis between January 1, 2000 and December 31, 2010. For the control group, 4 patients without endocarditis were frequency matched to each endocarditis patient according to age, sex, and index year. Competing risks regression analysis was conducted to determine the effect of endocarditis on cancer risk.A large difference was noted in Charlson comorbidity index between endocarditis and nonendocarditis patients. In patients with endocarditis, the risk for developing overall cancer was significant and 119% higher than in patients without endocarditis (adjusted subhazard ratio = 2.19, 95% confidence interval = 1.98-2.42). Regarding individual cancers, in addition to head and neck, uterus, female breast and hematological malignancies, the risks of developing colorectal cancer, and some digestive tract cancers were significantly higher. Additional analyses determined that the association of cancer with endocarditis is stronger within the 1st 5 years after endocarditis diagnosis.This population-based cohort study found that patients with endocarditis are at a higher risk for colorectal cancer and other cancers in Taiwan. The risk was even higher within the 1st 5 years after endocarditis diagnosis. It suggested that endocarditis is an early marker of colorectal cancer and other cancers. The underlying mechanisms must still be explored and may account for a shared risk factor of infection in both endocarditis and malignancy.

O envolvimento pulmonar por PM é pouco frequente, estando descrito na literatura em cerca de 10% de casos. Os autores apresentam um caso de uma mulher de 75 anos, com queixas de febre, perda ponderal, artralgias, mialgias e diminuição simétrica e proximal da força muscular com impotência funcional dos membros superiores e inferiores, com início um mês antes do internamento. Apresentava infiltrados pulmonares na telerradiografia de tórax. Após estudo exaustivo estabeleceu -se o diagnóstico de envolvimento pulmonar na forma de pneumonia organizativa por PM. Efectuou-se corticoterapia e terapêutica com micofenolato com melhoria clínica, analítica e radiológica. Conclusão: Neste caso, foi a alteração na telerradiografia de tórax numa doente sem sintomatologia respiratória que levou ao estudo exaustivo até ao diagnóstico de PM, realçando mais uma vez a importância da telerradiografia no rastreio de patologias de outros foros.Introduction: Polymyositis and dermatomyositis are classified as idiopathic inflammatory myopathies. Interstitial lung disease is rare and is described in the literature in about 10% of cases. The authors describes a case of 75 year old woman presenting with one month evolution of fever, weight loss, arthralgia, myalgia and symmetric and proximal muscle weakness of upper and lower limbs. Nonspecific interstitial changes was found in chest X -ray. After exhaustive study, the diagnosis of pulmonary envolvement in the form of organizing pneumonia by polymyositis, was established. Glucocorticoids and mycophenolate were prescribed with good clinical, analytical and radiological outcome. Conclusion: In this case, it was the changes in the chest X -ray in a patient without respiratory symptomatology, that conducted to exhaustive study to polymyositis diagnosis, enhancing once again the importance of X

    Staphylococcus caprae is a rare cause of infective endocarditis. Here, we report a case involving the native mitral valve in the absence of an implantable cardiac electronic device. A 76-year-old man presented with a 2 week history of confusion and pyrexia. His past medical history included an open reduction and internal fixation of a humeral fracture 17 years previously, which remained non-united despite further revision 4 years later. There was no history of immunocompromise or farm-animal contact. Two sets of blood culture bottles, more than 12 h apart, were positive for S. caprae . Trans-thoracic echocardiography revealed a 1×1.2 cm vegetation on the mitral valve, with moderate mitral regurgitation. Due to ongoing confusion, he had a magnetic resonance imaging brain scan, which showed a subacute small vessel infarct consistent with a thromboembolic source. A humeral SPECT-CT (single-photon emission computerized tomography-computerized tomography) scan showed no clear evidence of acute osteomyelitis. Surgical vegetectomy and mitral-valve repair were considered to reduce the risk of further systemic embolism and progressive valve infection. However, the potential risks of surgery to this patient led to a decision to pursue a cure with antibiotic therapy alone. He remained well 3 months after discharge, with repeat echocardiography demonstrating a reduction in the size of the vegetation (0.9 cm). Management of this infection was challenging due to its rarity and its unclear progression, complicated by the dilemma surrounding surgical intervention in a patient with a complex medical background.

    Abstract To determine the prevalence of antineutrophil cytoplasmic antibodies (ANCA) in patients with infective endocarditis (IE) in internal medicine; and to compare clinical and biochemical features and outcome between patients exhibiting IE with and without ANCA. Fifty consecutive patients with IE underwent ANCA testing. The medical records of these patients were reviewed. Of the 50 patients with IE, 12 exhibited ANCA (24%). ANCA-positive patients with IE exhibited: longer duration between the onset of first symptoms and IE diagnosis (P = 0.02); and more frequently: weight loss (P = 0.017) and renal impairment (P = 0.08), lower levels of C-reactive protein (P = 0.0009) and serum albumin (P = 0.0032), involvement of both aortic and mitral valves (P = 0.009), and longer hospital stay (P = 0.016). Under multivariate analysis, significant factors for ANCA-associated IE were: longer hospital stay (P = 0.004), lower level of serum albumin (P = 0.02), and multiple valve involvement (P = 0.04). Mortality rate was 25% in ANCA patients; death was because of IE complications in all these patients. Our study identifies a high prevalence of ANCA in unselected patients with IE in internal medicine (24%). Our findings further underscore that ANCA may be associated with a subacute form of IE leading to multiple valve involvement and more frequent renal impairment. Because death was due to IE complications in all patients, our data suggest that aggressive therapy may be required to improve such patients’ outcome. PMID:26817911

    This paper reports on the results and complications of aortoiliac balloon percutaneous transluminal angioplasty (PTA) and Simpson atherectomy that are compared to determine the role of the latter procedure in the management of aortoiliac disease. In 1984--1988, 92 patients underwent 126 angioplasties of the aortoiliac region. In 1986--1989, 21 patients underwent iliac artery atherectomy. Both groups had similar symptoms, risk factors, and age ranges. The overall technical success rate was 97.6or PTA and 100% for atherectomy. The initial clinical success was 92.8% for PTA and 100% for atherectomy. The 2-year clinical patency rate was 60% for PTA and 64% for artherectomy. Complications requiring surgery occurred in four of 126 (3%) PTA patients and one of 21 (5%) atherectomy patients. Groin hematomas were observed in 16% of PTA patients and 19% of atherectomy patients

    Full Text Available The clinical presentation of infective endocarditis varies according to theetiologic agent and the host. In elderly individuals, infective endocarditis canbe difficult to diagnose and poses a challenge for the physician. The course ofsubacute infective endocarditis is indolent, and the onset of cardiac structurallesion is slow and gradual. In elderly patients, anemia and weight loss areoccasionally the only or the most striking symptoms. In such cases, the clinicalreasoning process leads to a hypothesis of wasting syndrome or neoplasticdisease, especially when there is no fever. We report the case of an elderlypatient who had mitral insufficiency due to degenerative valve disease andpresented with bacterial endocarditis due to Streptococcus mitis. The patientwas not treated, because the diagnosis was not established in a timely manner.It is of note that the patient presented with marked weight loss and no fever.The autopsy revealed impairment of the mitral valve and left atrium due toendocarditis, as well as lung involvement due to chronic inhalation of smokefrom biomass burning, such as that produced by wood-burning stoves.

    Full Text Available In humans, one of the major factors associated with infective endocarditis (IE is the concurrent presence of periodontal disease (PD. However, in veterinary medicine, the relevance of PD in the evolution of dogs' endocarditis remains poorly understood. In order to try to establish a correlation between mouth-associated Enterococcus spp. and infective endocarditis in dogs, the present study evaluated the presence and diversity of enterococci in the gum and heart of dogs with PD. Samples were collected during necropsy of 32 dogs with PD and visually diagnosed with IE, which died of natural causes or euthanasia. Enterococci were isolated, identified and further characterized by Pulsed-Field Gel Electrophoresis (PFGE; susceptibility to antimicrobial agents and pathogenicity potential was also evaluated. In seven sampled animals, PFGE-patterns, resistance and virulence profiles were found to be identical between mouth and heart enterococci obtained from the same dog, allowing the establishment of an association between enterococcal periodontal disease and endocarditis in dogs. These findings represent a crucial step towards understanding the pathogenesis of PD-driven IE, and constitute a major progress in veterinary medicine.

    Assess clinical and serological data as parameters indicative of a possible evolution to endocarditis after an episode of acute Q fever. Retrospective cohort study of evolution to endocarditis after an acute Q fever episode, analyzing the clinical and serological evolution and the antibiotic treatment administered. Eighty patients were recruited, 20% of whom had phase i IgG antibody levels ≥ 1:1024 in the first 3 months. Only 44% of the patients underwent antibiotherapy in the acute phase; only 2 patients underwent extended antibiotherapy. Fifteen percent of the patients underwent an echocardiogram. None of the patients had symptoms suggestive of chronic infection or progressed to endocarditis after a median follow-up of 100 months, regardless of the early increase in phase i IgG antibodies. The early increase in phase i IgG antibodies in asymptomatic patients is not associated with progression to endocarditis despite not undergoing prolonged antibiotic treatment.

    Dentigenous, infectious foci are frequently associated with the development of various diseases. The role of such foci in the evolution of endocarditis still remains unclear. This article presents the concluding results of an interdisciplinary study verifying the influence of dentigenous, infectious foci on the development of infective endocarditis. The study subjects were 60 adult patients with history of infective endocarditis and coexistent acquired heart disease, along with the presence at least 2 odontogenic infectious foci (ie, 2 or more teeth with gangrenous pulp and periodontitis). The group had earlier been qualified for the procedure of heart valve replacement. Swabs of removed heart valve tissue with inflammatory lesions and blood were then examined microbiologically. Swabs of root canals and their periapical areas, of periodontal pockets, and of heart valves were also collected. Microbial flora, cultured from intradental foci, blood and heart valves, fully corresponded in 14 patients. This was accompanied in almost all cases by more advanced periodontitis (2nd degree, Scandinavian classification), irrespective of the bacterial co-occurrence mentioned. In the remaining patients, such consistency was not found. Among various dentigenous, infectious foci, the intradental foci appear to constitute a risk factor for infective endocarditis.

    Full Text Available Abstract Background Granulomas caused by Mycobacterium Tuberculosis have been observed at autopsy in the heart, pre-dominantly in the myocardium and endocardium, but rarely involving the coronary vessels and valvular structures. Mycobacterium tuberculosis valvular endocarditis is extremely rare, with most reports coming from autopsy series. Case presentation We report the case of a 17 year old immunocompetent girl who presented with history of fever, malaise, foot gangrene and a left sided hemiparesis. On investigation she was found to have infective endocarditis involving the aortic, mitral and tricuspid valves. She had developed a right middle cerebral artery stroke. She underwent dual valve replacement and tricuspid repair. The vegetations showed granulomatous inflammation but blood cultures and other biological specimen cultures were negative for any organisms. She was started on antituberculous treatment and anticoagulation. Conclusion This is the first reported case of triple valve endocarditis by Mycobacterium Tuberculosis in an immunocompetent host. Especially important is the fact that the right heart is involved which has been historically described in the setting of intravenous drug abuse. This implies that Tuberculosis should be considered in cases of culture negative endocarditis in endemic areas like Pakistan even in immunocompetent hosts.

    Although rare, infective endocarditis (IE) continues to cause significant morbidity and mortality. Previous data from the American University of Beirut Medical Center (AUBMC) had shown predominance of streptococcal infection. As worldwide studies in developed countries show increasing trends in Staphylococcus aureus endocarditis, it becomes vital to continually inspect local data for epidemiological variations. We reviewed all IE cases between 2001 and 2014, and we performed a comparison to a historical cohort of 86 IE cases from 1987 to 2001. A total of 80 patients were diagnosed with IE between 2001 and 2014. The mean age was 61 years. The most commonly isolated organisms were streptococci (37%), compared to 51% in the previous cohort. S. aureus accounted for 11%. Only one S. aureus isolate was methicillin-resistant. In the historical cohort, 26% of cases were caused by S. aureus. Enterococci ranked behind staphylococci with 22% of total cases, while in the previous cohort, enterococcal IE was only 4%. Compared to previous data from AUBMC, the rates of streptococcal and staphylococcal endocarditis have decreased while enterococcal endocarditis has increased. This study reconfirms that in Lebanon, a developing country, we continue to have a low predominance of staphylococci as etiologic agents in IE. Copyright © 2017 The Authors.

    Surgical treatment for endocarditis patients with a perivalvular abscess is still challenging.Methods and Results:From 2009 to 2016, 470 patients underwent surgery for active endocarditis at 11 hospitals. Of these, 226 patients underwent aortic valve surgery. We compared the clinical results of 162 patients without a perivalvular abscess, 37 patients who required patch reconstruction of the aortic annulus (PR group) and 27 who underwent aortic root replacement (ARR group). Patients with a perivalvular abscess had a greater number ofStaphylococcusspecies and prosthetic valve endocarditis, a greater level of inflammation at diagnosis and symptomatic heart failure before surgery, especially in the ARR group. Nevertheless, the duration between diagnosis and surgery was similar, because of a high prevalence of intracranial hemorrhage in the ARR group. Hospital death occurred in 13 (9%) patients without a perivalvular abscess, in 4 (12%) in the PR and in 7 (32%) in the ARR group. Postoperative inflammation and end-organ function were similar between the groups. Overall survival of patients without a perivalvular abscess and that of the PR group was similar, but was significantly worse in the ARR group (P=0.050, 0.026). Freedom from endocarditis recurrence was similar among all patients. Patients treated with patch reconstruction showed favorable clinical results. Early surgical intervention is necessary when a refractory invasive infection is suspected.

    1978-01-01

    Technetium-99m stannous pyrophosphate (/sup 99m/Tc-PYP) cardiac scintigraphy was performed in 15 rabbits with experimental Streptococcus sanguis aortic-valve infective endocarditis. The animals were imaged five to seven days after the administration of bacteria, and in each case abnormal accumulation of the tracer was visualized in the region of the aortic valve. Three types of cardiac scintigraphic patterns were demonstrated: focal, multifocal, and extensive, each correlating well with the anatomical extent of the lesion as defined by gross pathology. Tissue distribution studies demonstrated a 30 +- 5.3 (mean +- SEM) fold excess of radionuclide uptake in the infective endocarditis lesion compared with that of normal myocardium. Imaging of excised hearts from four animals showed an excellent correlation with in vivo imaging as well as gross pathology. Five animals with nonbacterial thrombotic aortic valve endocarditis demonstrated similar scintigraphic and tissue distribution results. In contrast, four normal animals failed to demonstrate abnormal /sup 99m/Tc-PYP cardiac scintigrams or tissue uptake. This study demonstrates that /sup 99m/Tc-PYP cardiac scintigraphy is a sensitive technique to detect experimental aortic valve endocarditis

    2016-08-01

    In 2007, the American Heart Association modified the infective endocarditis prophylaxis guidelines by limiting the use of antibiotics in patients with cardiac conditions associated with the highest risk of adverse outcomes after infective endocarditis. Our objective was to evaluate current practice for infective endocarditis prophylaxis among paediatric cardiologists. A web-based survey focussing on current practice, describing the use of antibiotics for infective endocarditis prophylaxis in various congenital and acquired heart diseases, was distributed via e-mail to paediatric cardiologists. The survey was kept anonymous and was distributed twice. Data from 253 participants were analysed. Most paediatric cardiologists discontinued infective endocarditis prophylaxis in patients with simple lesions such as small ventricular septal defect, patent ductus arteriosus, and bicuspid aortic valve without stenosis or regurgitation; however, significant disagreement persists in prescribing infective endocarditis prophylaxis in certain conditions such as rheumatic heart disease, Fontan palliation without fenestration, and the Ross procedure. Use of antibiotic prophylaxis in certain selected conditions for which infective endocarditis prophylaxis has been indicated as per the current guidelines varies from 44 to 83%. Only 44% follow the current guidelines exclusively, and 34% regularly discuss the importance of oral hygiene with their patients at risk for infective endocarditis. Significant heterogeneity still persists in recommending infective endocarditis prophylaxis for several cardiac lesions among paediatric cardiologists. More than half of the participants (56%) do not follow the current guidelines exclusively in their practice. Counselling for optimal oral health in patients at risk for infective endocarditis needs to be optimised in the current practice.

    ABSTRACT Infective endocarditis and kidney infections are serious complications of Staphylococcus aureus sepsis. We investigated the role of superantigens (SAgs) in the development of lethal sepsis, infective endocarditis, and kidney infections. SAgs cause toxic shock syndrome, but it is unclear if SAgs contribute to infective endocarditis and kidney infections secondary to sepsis. We show in the methicillin-resistant S. aureus strain MW2 that lethal sepsis, infective endocarditis, and kidney infections in rabbits are critically dependent on high-level SAgs. In contrast, the isogenic strain lacking staphylococcal enterotoxin C (SEC), the major SAg in this strain, is attenuated in virulence, while complementation restores disease production. SAgs’ role in infective endocarditis appears to be both superantigenicity and direct endothelial cell stimulation. Maintenance of elevated blood pressure by fluid therapy significantly protects from infective endocarditis, possibly through preventing bacterial accumulation on valves and increased SAg elimination. These data should facilitate better methods to manage these serious illnesses. PMID:23963178

    2017-05-01

    Full Text Available Infective endocarditis is a lethal and challenging multifaceted disease that can involve any vascularized system. We believe that multimodality imaging is invaluable to provide a comprehensive diagnosis. Our management approach to infective endocarditis adheres to a combination of the AHA, ACC, STS, and ESC guidelines. With the rapidly increasing transcatheter valve population, we expect an increased caseload of infective endocarditis. Beyond patients with hemorrhagic strokes, we advocate for early surgery if medical management has failed. Furthermore, a multidisciplinary team approach is imperative in infective endocarditis, and clear communication reduces the time to diagnosis and definitive treatment for this patient population.

Busca-se a melhor compreensão dos mecanismos de lesão envolvendo resposta inflamatória mediada pelas citocinas para o desenvolvimento de novas estratégias protetoras. Pesquisou-se na base de dados PubMed, incluindo artigos relevantes, os unitermos "ventilator induced lung injury preterm", "continuous positive airway pressure", "preterm" e "bronchopulmonary dysplasia". Dados e informações significativas foram compilados em tópicos, com o objetivo de formar uma visão crítica e plena acerca da lesão induzida pela ventilação e de suas consequências ao prematuro. Foi revisado o papel das citocinas pró-inflamatórias como mediadores da lesão, especialmente interleucinas 6 e 8, e fator de necrose tumoral alfa. Foram apresentadas evidências em estudos com animais e também em humanos, mostrando que breves períodos de ventilação mecânica são suficientes para a liberação dessas interleucinas inflamatórias. Também foram revisadas outras formas de ventilação mecânica e de ventilação não invasiva, como alternativas protetoras aos modos convencionais. Concluiu-se que o uso de ventilação não invasiva, a intubação com administração precoce de surfactante e a extubação rápida para CPAP nasal, além de estratégias que regulam o volume corrente evitando o volutrauma (como a ventilação com volume garantido, são medidas protetoras da lesão pulmonar induzida pela ventilação mecânica no prematuro.

    Full Text Available La enfermedad pulmonar obstructiva crónica (EPOC ha aumentado su prevalencia en el sexo femenino. Los casos de mujeres se describen como más sintomáticas. A pesar de que la EPOC se ha vinculado a elevado riesgo cardiovascular, hay pocos estudios sobre diferencias por sexo. El objetivo de nuestro estudio fue determinar la influencia del sexo sobre calidad de vida y síntomas, tratamiento, factores de riesgo y enfermedad cardiovascular (ECV en una población de pacientes con EPOC. En este estudio prospectivo observacional de corte transversal, se incluyeron pacientes con EPOC ingresados consecutivamente entre el 1 de septiembre de 2008 al 1 de marzo de 2010. Se registraron edad, sexo, habito tabáquico, factores de riesgo y enfermedad cardiovascular, tratamiento y gravedad de la EPOC. Se midió índice tobillo-brazo (ITB y se realizó Euroqol-5D.

    Full Text Available Streptococcus parasanguinis is a natural member of oral flora. It is an opportunistic pathogen, and rarely cause systemic infections due to it's low virulence. Subacute infective endocarditis may present with various clinical manifestations (eg., spondylodiscitis. A sixty-five years old male patient from Northern Iraq has referred to our emergency service with high fever, weight loss, back pain and inability to walk. The patient was a veterinarian. He was operated three years ago for colonic carcinoma and irradiated. In magnetic resonance imaging, spondylodiscitis was detected localized in lumbar 1-2 region. Transthorasic echocardiography demonstrated aortic valve vegetation. S. parasanguinis was identified in the blood cultures. In conclusion; all in all, it's remarkable to isolate S. parasanguinis as a causal agent of infective endocarditis in a patient who is a veterinarian with history of colonic carcinoma presented with clinical manifestation of spondylodiscitis.

    2016-09-01

    Granulomatosis with polyangiitis (GPA) is a rare but serious small vessel vasculitis with heterogeneous clinical presentation ranging from mainly localised disease with a chronic course, to a florid, acute small vessel vasculitic form characterised by severe pulmonary haemorrhage and/or rapidly progressive vasculitis or other severe systemic vasculitic manifestations. Cardiac involvement is, however, uncommon in the paediatric population. We report a case of a 16-year-old male who presented with peripheral gangrene and vegetation with unusual location on the supporting apparatus of the tricuspid valve, initially considered to have infective endocarditis but ultimately diagnosed with GPA. We provide an overview of the limited literature relating to cardiac involvement in GPA, and the diagnostic challenge relating to infective endocarditis in this context, especially focusing on the interpretation of the antineutrophil cytoplasmic antibody (ANCA) and the characteristic clinical features to identify in order to promptly recognise GPA, since timely diagnosis and treatment are essential for this potentially life-threatening condition.

    The rarity of invasiveness of right-sided infective endocarditis (IE) compared with left-sided has not been well recognized and evaluated. Thus, we compared invasiveness of right- versus left-sided IE in surgically treated patients. From January 2002 to January 2015, 1292 patients underwent surgery for active IE, 138 right-sided and 1224 left-sided. Among patients with right-sided IE, 131 had tricuspid and 7 pulmonary valve IE; 12% had prosthetic valve endocarditis. Endocarditis-related invasiveness was based on echocardiographic and operative findings. Invasive disease was rare on the right side, occurring in 1 patient (0.72%; 95% confidence interval 0.02%-4.0%); rather, it was limited to valve cusps/leaflets or was superficial. In contrast, IE was invasive in 408 of 633 patients with aortic valve (AV) IE (65%), 113 of 369 with mitral valve (MV) IE (31%), and 148 of 222 with AV and MV IE (67%). Staphylococcus aureus was a more predominant organism in right-sided than left-sided IE (right 40%, AV 19%, MV 29%), yet invasion was observed almost exclusively on the left side of the heart, which was more common and more severe with AV than MV IE and more common with prosthetic valve endocarditis than native valve IE. Rarity of right-sided invasion even when caused by S aureus suggests that invasion and development of cavities/"abscesses" in patients with IE may be driven more by chamber pressure than organism, along with other reported host-microbial interactions. The lesser invasiveness of MV compared with AV IE suggests a similar mechanism: decompression of MV annulus invasion site(s) toward the left atrium.

    Full Text Available Objective: We have retrospectively analyzed the results of the operations made for aortic valve endocarditis in a single center in 26 years. Methods: From June 1985 to January 2011, 174 patients were operated for aortic valve endocarditis. One hundred and thirty-eight (79.3% patients were male and the mean age was 39.3±14.4 (9-77 years. Twenty-seven (15.5% patients had prosthetic valve endocarditis. The mean duration of follow-up was 7.3±4.2 years (0.1-18.2 adding up to a total of 1030.8 patient/years. Results: Two hundred and eighty-two procedures were performed. The most frequently performed procedure was aortic valve replacement with mechanical prosthesis (81.6%. In-hospital mortality occurred in 27 (15.5% cases. Postoperatively, 25 (14.4% patients had low cardiac output and 17 (9.8% heart block. The actuarial survival rates for 10 and 15 years were 74.6±3.7% and 61.1±10.3%, respectively. In-hospital mortality was found to be associated with female gender, emergency operation, postoperative renal failure and low cardiac output. The long term mortality was significantly associated with mitral valve involvement. Male gender was found to be a significant risk factor for recurrence in the follow-up. Conclusion: Surgery for aortic valve endocarditis has significant mortality. Emergency operation, female gender, postoperative renal failure and low cardiac output are significant risk factors. Risk for recurrence and need for reoperation is low.

    Rhabdomyolysis has multiple etiologies with unclear mechanisms; however, rhabdomyolysis caused by Staphylococcus aureus infection is rare. A case report of severe rhabdomyolysis in a patient who presented with endocarditis caused by methicillin-susceptible S. aureus and review of relevant literature. The patient had a history of cardiac surgery for tetralogy of Fallot. He was admitted to the hospital because of fever and digestive symptoms. Respiratory and hemodynamic status deteriorated rapidly, leading to admission to the intensive care unit (ICU) for mechanical ventilation and vasopressor support. Laboratory tests disclosed severe rhabdomyolysis with a serum concentration of creatine kinase that peaked at 49,068 IU/L; all blood cultures grew methicillin-susceptible S. aureus. Antibiotic therapy was amoxicillin-clavulanic acid, ciprofloxacin, and gentamicin initially and was changed subsequently to oxacillin, clindamycin, and gentamicin. Transesophageal echocardiography showed vegetation on the pulmonary valve, thus confirming the diagnosis of acute endocarditis. Viral testing and computed tomography (CT) scan ruled out any obvious alternative etiology for rhabdomyolysis. Bacterial analysis did not reveal any specificity of the staphylococcal strain. The patient improved with antibiotics and was discharged from the ICU on day 26. He underwent redux surgery for valve replacement on day 53. Staphylococcal endocarditis should be suspected in cases of severe unexplained rhabdomyolysis with acute infectious symptoms.

    Infective endocarditis can be acute or subacute, depending on the virulence of the causative organism. It can also cause loss of vision by a variety of mechanisms, ranging from embolic retinal artery occlusion to endogenous endophthalmitis. We illustrate the first report of foveal cyst formation secondary to infective endocarditis. A 53-year-old man presented to his general practitioner with a variety of constitutional symptoms, but initial laboratory and imaging investigations revealed only mild normocytic anaemia, and he was discharged from further medical care. Four weeks later he developed bilateral visual loss associated with whitish lesions of the superficial retina at both foveae. These later developed into foveal cysts with disruption of the photoreceptor inner segment-outer segment junction and persistent poor visual acuity of 6/60 OU. No retinal haemorrhages or Roth spots were noted. Only after he presented with visual loss did further investigations reveal the underlying diagnosis of streptococcal endocarditis. Ophthalmologists assessing retinal pathology which presents in association with undiagnosed constitutional symptoms are advised to refer such patients promptly for thorough medical investigation, including blood culture and echocardiography where appropriate.

    The optimal timing of surgical treatment for infective endocarditis complicated by cerebrovascular events is controversial, largely due to the perceived risk of perioperative intracranial bleeding. Current guidelines suggest waiting 2 weeks between the diagnosis of stroke and surgery. The aim of this study was to investigate the clinical and neurological outcomes of early surgery following a stroke. This was a single-center retrospective analysis of 12 consecutive patients requiring surgery for infective endocarditis between 2011 and 2014 at Rush University Medical Center, with either ischemic (n = 6) and/or hemorrhagic (n = 6) cerebrovascular complications. All underwent computed tomographic angiography prior to early valve reconstructive surgery to identify potentially actionable neurological findings. Early valve surgery was performed for ongoing sepsis or persistent emboli. Neurologic risk and outcome were assessed pre- and postoperatively using the National Institutes of Health Stroke Scale and the Glasgow Outcome Scale, respectively. All 12 patients underwent surgical treatment within 10 days of the diagnosis of stroke. Mortality in the immediate postoperative period was 8%. Eleven of the 12 patients exhibited good neurological recovery in the immediate postoperative period, with a Glasgow Outcome Scale score ≥ 3. There was no correlation between duration of cardiopulmonary bypass and neurological outcomes. Early cardiac surgery in patients with infective endocarditis and stroke maybe lifesaving with a low neurological risk. Comprehensive neurovascular imaging may help in identifying patient-related risk factors. © The Author(s) 2016.

    In this review, we examine the central role of echocardiography in the diagnosis, prognosis, and management of infective endocarditis (IE). 2D transthoracic echocardiography (TTE) and transesophageal echocardiography TEE have complementary roles and are unequivocally the mainstay of diagnostic imaging in IE. The advent of 3D and multiplanar imaging have greatly enhanced the ability of the imager to evaluate cardiac structure and function. Technologic advances in 3D imaging allow for the reconstruction of realistic anatomic images that in turn have positively impacted IE-related surgical planning and intervention. CT and metabolic imaging appear to be emerging as promising ancillary diagnostic tools that could be deployed in select scenarios to circumvent some of the limitations of echocardiography. Our review summarizes the indispensable and central role of various echocardiographic modalities in the management of infective endocarditis. The complementary role of 2D TTE and TEE are discussed and areas where 3D TEE offers incremental value highlighted. An algorithm summarizing a contemporary approach to the workup of endocarditis is provided and major societal guidelines for timing of surgery are reviewed.

    Candida Endocarditis (CE) is a deadly disease. It is of paramount importance to assess risk factors for acquisition of both Candida native (NVE) and prosthetic (PVE) valve endocarditis and relate clinical features and treatment strategies with the outcome of the disease. Areas covered: We searched the literature using the Pubmed database. Cases of CE from the Italian Study on Endocarditis (SEI) were also included. Overall, 140 cases of CE were analyzed. Patients with a history of abdominal surgery and antibiotic exposure had higher probability of developing NVE than PVE. In the PVE group, time to onset of CE was significantly lower for biological prosthesis compared to mechanical prosthesis. In the whole population, greater age and longer time to diagnosis were associated with increased likelihood of death. Patients with effective anti-biofilm treatment, patients who underwent cardiac surgery and patients who were administered chronic suppressive antifungal treatment showed increased survival. For PVE, moderate active anti-biofilm and highly active anti-biofilm treatment were associated with lower mortality. Expert commentary: Both NVE and PVE could be considered biofilm-related diseases, pathogenetically characterized by Candida intestinal translocation and initial transient candidemia. Cardiac surgery, EAB treatment and chronic suppressive therapy might be crucial in increasing patient survival.

    Intimal proliferation or Neointimal hyperplasia (NIH) is a vascular lesion that often arises in arteries after balloon angioplasty or other vessel wall injuries. FIH is a vascular lesion that develops in autologous saphenous vein grafts (SVG) after transplantation into the aorto-coronary circulation or the peripheral vascular circulation. FIH shares elements of smooth muscle migration, proliferation and fibrous tissue deposition in common with nibrointimal proliferation (NIH). Either NIH of a coronary artery or FIH of a SVG obstruct the vascular lumen and result in myocardial dysfunction. Local radiotherapy has been used for several decades to reduce the post-operative recurrence of the fibrovascular proliferations of pterygia and keloids. Similarly, in animal and human experiments, endovascular radiotherapy has been shown to reduce arterial smooth muscle proliferation. Consideration of the similarities of vascular smooth muscle cell proliferation in NIH and FIH leads one to suggest that endovascular beta irradiation can reduce FIH as well as it reduces NIH. The goal of such treatment is to achieve a clinically significant decrease in the morbidity and mortality resulting from SVG occlusions. The potential for large reduction of the consequences of SVG occlusion, the very large number of patients at risk, and the simplicity of the proposed intervention encourages prompt scientific evaluation of this technique.

    Prophylaxis and treatment guidelines for infective endocarditis have changed substantially over the past decade. In the United States, few population-based studies have explored the contemporary epidemiology and outcomes of endocarditis. To quantify trends in the incidence and etiologies of infective endocarditis in the United States. Retrospective population epidemiology study of patients hospitalized with a first episode of endocarditis identified from mandatory state databases in California and New York State between January 1, 1998, and December 31, 2013. Infective endocarditis. Outcomes were crude and standardized incidence of endocarditis and trends in patient characteristics and disease etiology. Trends in acquisition mode, organism, and mortality were analyzed. Among 75 829 patients with first episodes of endocarditis (mean [SD] age, 62.3 [18.9] years; 59.1% male), the standardized annual incidence was stable between 7.6 (95% CI, 7.4 to 7.9) and 7.8 (95% CI, 7.6 to 8.0) cases per 100 000 persons (annual percentage change [APC], -0.06%; 95% CI, -0.3% to 0.2%; P = .59). From 1998 through 2013, the proportion of patients with native-valve endocarditis decreased (from 74.5% to 68.4%; APC, -0.7%; 95% CI, -0.9% to -0.5%; P endocarditis increased (from 12.0% to 13.8%; APC, 1.3%; 95% CI, 0.8% to 1.7%; P endocarditis increased (from 1.3% to 4.1%; APC, 8.8%; 95% CI, 7.8% to 9.9%; P endocarditis decreased (from 17.7% to 15.3%; APC, -1.0%; 95% CI, -1.4% to -0.7%; P endocarditis increased (from 32.1% to 35.9%; APC, 0.8%; 95% CI, 0.5% to 1.1%; P endocarditis did not increase (unadjusted: APC, -0.1%; 95% CI, -0.8% to 0.6%; P = .77; adjusted: APC, -1.3%; 95% CI, -1.8% to -0.7%; P endocarditis was stable from 1998 through 2013, with changes in patient characteristics and etiology over this time.

As complicações respiratórias correspondem a aproximadamente 15% deste total. A mortalidade global dessa cirurgia é de 8,6%, mas em presença de complicações respiratórias, a taxa de mortalidade chega a 30%. O edema pulmonar pós-pneumonectomia é uma complicação rara (3% a 5%, mas muito grave, sendo fatal na maioria dos casos. Foi descrito pela primeira vez há pouco mais de vinte anos mas, apesar da gravidade alarmante, pouco sabemos acerca de sua fisiopatologia, embora muitas hipóteses tenham sido levantadas. Uma vez instalado, nenhuma medida é comprovadamente eficaz no seu tratamento. Vários fatores de risco estão associados ao aparecimento do edema pulmonar pós-pneumonectomia, dentre os quais a sobrecarga hídrica, que foi o primeiro fator evitado. Entretanto, muitos trabalhos mostram não haver relação direta entre o volume recebido e o desenvolvimento do edema. A prevenção é a melhor forma de evitá-lo e deve ser realizada de maneira multifatorial, envolvendo toda a equipe médica, desde o momento da anestesia até os cuidados cirúrgicos e na terapia intensiva. No entanto, tão importante quanto a prevenção, é a suspeita clínica precoce, identificando os pacientes em risco para essa grave complicação.Although pneumonectomy is a technically simple procedure, it has been associated with a high (60% incidence of complications.

    Heart valve repair or replacement is a serious problem. Patients can benefit from an open dialogue between both cardiologists and gastroenterologists for the optimal effective patients care. The focused update on infective endocarditis of the American College of Cardiology/American Heart Association 2008 (ACC/AHA guidelines) and guidelines on the prevention, diagnosis, and treatment of infective endocarditis (new version 2009) of the European Society of Cardiology (ESC guidelines) describe prophylaxis against infective endocarditis (IE) as not recommended for gastroscopy and colonoscopy in the absence of active infection but increasing evidence suggests that the role of IE antibiotic prophylaxis remains a dark side of the cardio-oncology prevention. New evidences concerning infective endocarditis due to Streptococcus bovis, Streptococcus agalactiae, Enterococcus faecalis, Enterococcus faecium, Enterococcus durans, and new findings indicate that there is a need for bacterial endocarditis prophylaxis in patients undergoing gastrointestinal endoscopy especially in elderly patients and in cancer and immunocompromised patients, to avoid serious consequences.

    Full Text Available Introduction. Enterococcus faecalis (E. faecalis, a constituent of the gut microbiota, can be associated with both colonic lesions and endocarditis. Since this microorganism is one of the endocarditis etiological agents, there is a need for greater study in regard to the association with endocarditis and colonic lesions. Case Presentation. This is the case description of a 53-year-old man with history of prolapse of the anterior mitral valve leaflet who was diagnosed with endocarditis by E. faecalis and treated with ampicillin and gentamicin. Upon investigation by colonoscopy, he was found to have a tubular adenoma with low grade dysplasia. Conclusion. There are a few descriptions in scientific literature of an association between endocarditis by E. faecalis and colonic lesions. However, further studies with significant correlation between the two pathologies are required, so that proper measures can be implemented in clinical practice.

    Introduction. Endocarditis caused by yeasts is currently an emerging cause of infective endocarditis and, when accompanied byfever of unknown origin, is more severe since interferes with proper diagnosis and endocarditis treatment. Case presentation. The Rio de Janeiro Infective Endocarditis Study Group reports a case of infectious endocarditis (IE) with negative blood cultures in a 45-year-old white female resident in Rio de Janeiro, Brazil, previously submitted to kidney transplantation. After diagnosis and intervention, the valve culture revealed Rhodotorula mucilaginosa. The clinical aspects and overview of endocarditis caused by Rhodotorula spp. demonstrated that R. muscilaginosa have been isolated from the last IE cases from kidney transplanted patients. Conclusion. Though most of the patients (in literature) recovered well from endocarditis caused by Rhodotorula spp., physicians must be aware for diagnosis of fungemia and fungal treatment in kidney transplanted patients suffering of fever of unknown origin in the modern immunosuppressive treatment.

Os pacientes podem ter dispneia progressiva e tosse, às vezes acompanhadas pelo agravamento da hipóxia, e seu curso pode variar de deterioração progressiva a melhora espontânea. Muitas terapias foram usadas, incluindo antibióticos, drenagem postural e ventilação com pressão positiva intermitente com acetilcisteína, heparina e soro fisiológico em aerossol. Atualmente, a base do tratamento é a lavagem pulmonar total (LPT. A LPT, embora seja geralmente bem-tolerada, pode estar associada a algumas complicações. RELATO DE CASO: Relatamos um caso de PAP grave durante o procedimento anestésico e as complicações no manejo da proteinose alveolar pulmonar em um paciente que havia sido submetido a múltiplas e alternadas lavagens de um dos pulmões ao longo de sete anos (os últimos três em nosso hospital, com melhora dos sintomas depois de cada tratamento.

    Full Text Available Os autores estudaram a existência de hemosiderose pulmonar em 60 casou de autopsia, 20 dos quais chagásicos crônicos com cardiopatia, 20 pacientes com cardiopatia não chagásica e 20 casos sem nenhuma manifestação de doença cardíaca. A incidência de hemossiderose pulmonar foi de 75% entre os chagásicos e de 80% entre os pacientes de cardiopatia não chagásica. Nos casos controle sem cardiopatia a incidência foi relativamente baixa (45% e, guando presente, o grau de intensidade era mínimo. Com esses achados, conclui-se que a hemossiderose pulmonar na Doença de Chagas é uma conseqüência da congestão crônica passiva, resultante da insuficiência cardíaca congestiva, do mesmo modo que ocorre em outras condições mórbidas tais como Estenose mitral e Cor-pulmonar crônico, não havendo evidências de uma pneumopatia peculiar em chagásicos.

Isto levou a uma reavaliação do espécime pulmonar que revelou, além da bronquiectasia inflamatória, nódulos de pequenas células fusiformes no parênquima pulmonar, semelhantes a nódulos pulmonares de tipo meningotelial, mas com positividade imunohistoquímica para actina do músculo liso. A hipótese de desenvolvimento inicial de linfangioleiomiomatose pulmonar é discutida. Abstract: A 68 year old woman was submitted to a mediastinal lymphangioleiomyoma resection found in a follow-up study of lower left lung resection due to bronchiectasis complicated by chylothorax. This led to a revaluation of the pulmonary specimen that revealed, in addition to inflammatory bronchiectasis, small spindle cell nodules in the lung parenchyma, similar to minute pulmonary meningothelial-like nodules, but with smooth muscle actin immunohistochemical positivity. The possibility of initial pulmonary development of lymphangioleiomyomatosis is discussed.

    We report an unusual case of endocarditis occurring in a 74-year-old man with a history of systemic hypertension, diabetes mellitus and minor amputation for left forefoot ulcer. The patient was hospitalized for vacuum-assisted closure therapy to aid in wound healing. After the first treatment session, the patient reported abdominal pain with haematemesis and fever (40 °C). Owing to persistent fever, three blood cultures were performed, all positive for Kocuria kristinae. The identification was based on biochemical tests and automated systems. The speciation of the micro-organism was achieved with MALDI-TOF and then confirmed by 16S rRNA gene sequencing. Transthoracic echocardiographic examination showed the presence of a large vegetation (38×20 mm) on the posterior mitral leaflet and moderate mitral regurgitation. Since there are no current guidelines for the treatment of K. kristinae endocarditis, empiric antibiotic therapy with intravenous sulbactam/ampicillin (1.5 g twice daily) and gentamicin (6 mg kg(-1) per day) was started. After 7 days of hospitalization, the patient's condition suddenly worsened because of the occurrence of haemorrhagic stroke. Despite inotropic support and rifampicin infusion, the haemodynamic status progressively deteriorated. After an initial improvement, he worsened again, becoming stuporous, hypotensive and dyspnoeic. In the following days, the patient developed compartment syndrome resulting in right foot ischaemia. Unfortunately, 25 days after hospitalization, the patient died of multiple organ failure from overwhelming sepsis. To the best of our knowledge, this is the first case of K. kristinae endocarditis on a native valve that is not related to a central venous catheter but associated with diabetic foot infection.

    Full Text Available Since the 1960s, regular hemodialysis (HD was recognized as a risk factor for the development of infective endocarditis (IE, particularly at vascular access sites. The present report describes our experience at the Etat Major General Agadir, Morocco, of taking care of IE in patients on regular dialysis. A retrospective analysis was made of five cases of IE in patients receiving re-gular HD having arteriovenous fistula as vascular access. They were sent from four private centers and admitted in our formation between January 2004 and March 2009. Infective endocarditis was detected after 34.5 months following initiation of dialysis. The causative organisms included Sta-phylococcus and Enterococcus in two cases each and negative blood culture in one case. A recent history of infection (<3 months of the vascular access was found in three cases. Peripheric embolic phenomena were noted in two cases. A pre-existing heart disease was common and contributed to heart failure. Mortality was frequent due to valvular perforations and congestive heart failure, making the medical treatment alone unsatisfactory. Two patients survived and three of our patients received a prosthetic valve replacement, with a median survival after surgery of 10.3 months/person. The clinical diagnosis of infective endocarditis in regularly dialyzed patients remains difficult, with the presence of vascular calcification as a common risk factor. The vascular catheter infections are the cardinal gateway of pathogenic organisms, which are mainly Staphlococcus. The prognosis is bad and the mortality is significant, whereas medical and surgical treatments are often established in these patients who have many factors of comorbidity.

    Conclusiones: El mantenimiento de FPAC no incrementa la morbimortalidad post-Glenn ni altera la conservación funcional del ventrículo único, permitiendo llegar a la fase pre-Fontan con mayor SaO2 y mejor tamaño de ramas pulmonares. La existencia o ausencia de FPAC no influyó en los resultados del Fontan posterior, aunque consideramos interesante mantenerlo, especialmente en casos con ramas pulmonares pequeñas. La paliación pre-Glenn tipo banding pulmonar se asoció a mayor imposibilidad de conservar un FPAC.

The main imaging modalities used in the diagnosis are ventilation-perfusion (V/Q, scintigraphy, angiography, and computed tomography (CT. In the last decade several studies have demonstrated that spiral CT has a high sensitivity and specificity in the diagnosis of acute pulmonary thromboembolism. The evaluation of the pulmonary arteries has further improved with the recent introduction of multidetector spiral CT scanners. Various investigators have suggested that spiral CT pulmonary angiography should replace scintigraphy in the assessment of patients whose symptoms are suggestive of acute PE. This article discusses the role of the various imaging modalities in the diagnosis of acute pulmonary thromboembolism with emphasis on the role of spiral CT.

    Full Text Available Infective endocarditis (IE is an infection that does not usually respond rapidly to treatment, often because its early symptoms are non-specific. The diseased valves (native or bioprosthetic may be calcified and the thrombotic vegetations on them typically friable and embolize easily. Left untreated IE leads to damage to the infected valve and to congestive heart failure (CHF. Its treatment usually requires heart valve replacement. Our 69-year-old patient had IE, and underwent aortic valve replacement (AVR with a bioprosthesis. This case stresses the complications of IE and its tendency to recur in patients with bioprosthetic heart valves (BHV who previously had IE.

    Mycobacterium goodii is an infrequent human pathogen which has been implicated in prosthesis related infections and penetrating injuries. It is often initially misidentified as a gram-positive rod by clinical microbiologic laboratories and should be considered in the differential diagnosis. We describe here the second reported case of M. goodii endocarditis. Species level identification was performed by 16S rDNA (ribosomal deoxyribonucleic acid) gene sequencing. The patient was successfully treated with mitral valve replacement and a prolonged combination of ciprofloxacin and trimethoprim/sulfamethoxazole. Confirmation of the diagnosis utilizing molecular techniques and drug susceptibility testing allowed for successful treatment of this prosthetic infection.

Dentro de la patogenia de esta enfermedad, el Factor de Necrosis Tumoral es una citocina que juega un papel importante, una producción elevada de TNF-α se ha encontrado en la sinovial de estos pacientes, y por su capacidad de inducir la producción de otras citocinas, como IL-6, IL-17, GM-CSF, M-CSF, e incluso IL-1 y TNF-α (función autócrina, parecería que el TNF-α ejerce una acción “jerárquica” dentro de la llamada red de citocinas y una inhibición de su acción da como resultado un beneficio terapéutico en los pacientes con AR. Sin embargo, es conocido que la infección concurrente más frecuentemente informada con el uso de agentes biológicos (Anti-TNF es la TB, y la incidencia de ésta se ha incrementado desde el advenimiento de la terapia biológica. Por tanto, la descripción de este caso no corresponde a un hecho médico aislado, sino a una problemática actual y real. Este es el primer caso que se reporta en la Costa Caribe.

    Infective endocarditis is a life threatening complication of intravenous drug abuse, which continues to be a major burden with inadequately characterised long-term outcomes. We reviewed our institutional experience of surgical treatment of infective endocarditis in active intravenous drug abusers with the aim of identifying the determinants long-term outcome of this distinct subgroup of infective endocarditis patients. A total of 451 patients underwent surgery for infective endocarditis between January 1993 and July 2013 at the University Hospital of Heidelberg. Of these patients, 20 (7 female, mean age 35 ± 7.7 years) underwent surgery for infective endocarditis with a history of active intravenous drug abuse. Mean follow-up was 2504 ± 1842 days. Staphylococcus aureus was the most common pathogen detected in preoperative blood cultures. Two patients (10%) died before postoperative day 30. Survival at 1, 5 and 10 years was 90%, 85% and 85%, respectively. Freedom from reoperation was 100%. Higher NYHA functional class, higher EuroSCORE II, HIV infection, longer operating time, postoperative fever and higher requirement for red blood cell transfusion were associated with 90-day mortality. In active intravenous drug abusers, surgical treatment for infective endocarditis should be performed as extensively as possible and be followed by an aggressive postoperative antibiotic therapy to avoid high mortality. Early surgical intervention is advisable in patients with precipitous cardiac deterioration and under conditions of staphylococcal endocarditis. However, larger studies are necessary to confirm our preliminary results.

    To identify risk factors potentially associated with the development of bacterial endocarditis in dogs and determine whether periodontal disease and surgical procedures (oral and nonoral) were associated with bacterial endocarditis. Retrospective case-control study. 76 dogs with (cases) and 80 dogs without (controls) bacterial endocarditis. Medical records were reviewed for information on signalment, physical examination findings, recent medical history, and results of echocardiography, clinicopathologic testing, and necropsy. None of the dogs with endocarditis had a history of undergoing any dental or oral procedure in the 3 months prior to the diagnosis of endocarditis, and no significant difference was found between groups with regard to the prevalence of oral infection. Dogs with endocarditis were significantly more likely to have undergone a nonoral surgical procedure that required general anesthesia in the preceding 3 months or to have developed a new heart murmur or a change in intensity of an existing heart murmur. Preexisting cardiac dis-ease (congenital or acquired) was not found to be a risk factor. Results did not provide any evidence of an association between bacterial endocarditis in dogs and either dental or oral surgical procedures or oral infection. Findings suggested that the routine use of prophylactic antimicrobial administration in dogs undergoing oral procedures needs to be reevaluated.

    Case series have suggested that pneumococcal endocarditis is a rare disease, mostly reported in patients with co-morbidities but no underlying valve disease, with a rapid progression to heart failure, and high mortality. We performed a case-control study of 28 patients with pneumococcal endocarditis (cases), and 56 patients with non-pneumococcal endocarditis (controls), not matched for sex and age, during the years 1991-2013, in one referral centre. Alcoholism (39.3% versus 10.7%; p endocarditis. Cardiac surgery was required in 64.3% of patients with pneumococcal endocarditis, much earlier than in patients with non-pneumococcal endocarditis (mean time from symptom onset, 14.1 ± 18.2 versus 69.0 ± 61.1 days). In-hospital mortality rates were similar (7.1% versus 12.5%). Streptococcus pneumoniae causes rapidly progressive endocarditis requiring life-saving early cardiac surgery in most cases.

    Background Advancements in medical technology and increased life expectancy have been described as contributing to the evolution of endocarditis. We sought to determine whether there has been a change in the incidence, demographics, microbiology, complications, and outcomes of infective endocarditis over a ten-year time span. Methods We screened 28,420 transthoracic and transesophageal echocardiogram reports performed at our center for the following indications: fever, masses, emboli (including stroke), sepsis, bacteremia, and endocarditis in two time periods: 1999 through 2000 and 2009 through 2010. Data were collected from diagnosed endocarditis cases. Results Overall, 143 cases of infective endocarditis were analyzed (48 in 1999-2000 and 95 in 2009-2010). The endocarditis incidence per number of admissions remained nearly constant at 0.113% for 1999-2000 and 0.148% for 2009-2010 (p = 0.153). However, tricuspid valve involvement increased markedly from 6% to 36% (p endocarditis at our center has not changed and mortality remains high, but the “face of endocarditis” in Kentucky has evolved with an increased incidence of tricuspid valve involvement, valvular complications, and embolic events.

    Superantigens are indispensable virulence factors for Staphylococcus aureus in disease causation. Superantigens stimulate massive immune cell activation, leading to toxic shock syndrome (TSS) and contributing to other illnesses. However, superantigens differ in their capacities to induce body-wide effects. For many, their production, at least as tested in vitro, is not high enough to reach the circulation, or the proteins are not efficient in crossing epithelial and endothelial barriers, thus remaining within tissues or localized on mucosal surfaces where they exert only local effects. In this study, we address the role of TSS toxin-1 (TSST-1) and most importantly the enterotoxin gene cluster (egc) in infective endocarditis and sepsis, gaining insights into the body-wide versus local effects of superantigens. We examined S. aureus TSST-1 gene (tstH) and egc deletion strains in the rabbit model of infective endocarditis and sepsis. Importantly, we also assessed the ability of commercial human intravenous immunoglobulin (IVIG) plus vancomycin to alter the course of infective endocarditis and sepsis. TSST-1 contributed to infective endocarditis vegetations and lethal sepsis, while superantigens of the egc, a cluster with uncharacterized functions in S. aureus infections, promoted vegetation formation in infective endocarditis. IVIG plus vancomycin prevented lethality and stroke development in infective endocarditis and sepsis. Our studies support the local tissue effects of egc superantigens for establishment and progression of infective endocarditis providing evidence for their role in life-threatening illnesses. In contrast, TSST-1 contributes to both infective endocarditis and lethal sepsis. IVIG may be a useful adjunct therapy for infective endocarditis and sepsis.

    Infective endocarditis has been reported post Melody percutaneous pulmonary valve implant; the incidence and risk factors, however, remain poorly defined. We identified four cases of endocarditis from our first 25 Melody implants. Our aim was to examine these cases in the context of postulated risk factors and directly compare endocarditis rates with local surgical valves. We conducted a retrospective review of patients post Melody percutaneous pulmonary valve implant in New Zealand (October, 2009-May, 2015) and also reviewed the incidence of endocarditis in New Zealand among patients who have undergone surgical pulmonary valve implants. In total, 25 patients underwent Melody implantation at a median age of 18 years. At a median follow-up of 2.9 years, most were well with low valve gradient (median 27 mmHg) and only mild regurgitation. Two patients presented with life-threatening endocarditis and obstructive vegetations at 14 and 26 months post implant, respectively. Two additional patients presented with subacute endocarditis at 5.5 years post implant. From 2009 to May, 2015, 178 surgical pulmonic bioprostheses, largely Hancock valves and homografts, were used at our institution. At a median follow-up of 2.9 years, four patients (2%) had developed endocarditis in this group compared with 4/25 (16%) in the Melody group (p=0.0089). Three surgical valves have been replaced. The Melody valve offers a good alternative to surgical conduit replacement in selected patients. Many patients have excellent outcomes in the medium term. Endocarditis, however, can occur and if associated with obstruction can be life threatening. The risk for endocarditis in the Melody group was higher in comparison with that in a contemporaneous surgical pulmonary implant cohort.

    Objectives To determine the hospitalization rates and outcomes of endocarditis among older adults. Background Endocarditis is the most serious cardiovascular infection and is especially common among older adults. Little is known about recent trends for endocarditis hospitalizations and outcomes. Methods Using Medicare inpatient Standard Analytic Files, we identified all Fee-For-Service beneficiaries aged ≥65 years with a principal or secondary diagnosis of endocarditis from 1999-2010. We used Medicare Denominator Files to report hospitalizations per 100,000 person-years. Rates of 30-day and 1-year mortality were calculated using Vital Status Files. We used mixed-effects models to calculate adjusted rates of hospitalization and mortality and to compare the results before and after 2007, when the American Heart Association revised recommendations for endocarditis prophylaxis. Results Overall, 262,658 beneficiaries were hospitalized with endocarditis. The adjusted hospitalization rate increased from 1999-2005, reaching 83.5 per 100,000 person-years in 2005, and declined during 2006-2007. After 2007, the decline continued, reaching 70.6 per 100,000 person-years in 2010. Adjusted 30-day and 1-year mortality rates ranged from 14.2% to 16.5% and from 32.6% to 36.2%, respectively. There were no consistent changes in adjusted rates of 30-day and 1-year mortality after 2007. Trends in rates of hospitalization and outcomes were consistent across demographic subgroups. Adjusted rates of hospitalization and mortality declined consistently in the subgroup with principal diagnosis of endocarditis. Conclusions Our study highlights the high burden of endocarditis among older adults. We did not observe an increase in adjusted rates of hospitalization or mortality associated with endocarditis after publication of the 2007 guidelines. PMID:23994421

    Diagnosis and treatment of infective endocarditis (IE) is still a challenge for physicians. Group of patients with the worst prognosis is treated in Intensive Cardiac Care Unit (ICCU). Etiologic agent can not be identified in a substantial number of patients. The aim of study is to find differences between patients with blood culture negative infective endocarditis (BCNIE) and blood culture positive infective endocarditis (BCPIE) treated in ICCU by comparing their clinical course and laboratory parameters. Retrospective analysis of 30 patients with IE hospitalized in ICCU Swietokrzyskie Cardiac Centre between 2010 and 2016. This group consist of 26 men (86,67%) and 4 women (13,3%). Mean age was 58 years ±13. Most of the cases were new disease, recurrence of the disease was observed in 2 cases (6,7%). 8 patients (26,7%) required artificial ventilation, 11 (36,7%) received inotropes and 6 (20%) vasopresors. In 14 (46,7%) cases blood cultures was negative (BCNIE), the rest of patients (16, 53,3%) was blood cultures - positive infective endocarditis (BCIE). Both of the groups were clinically similar. There were no statistically significant differences in incidence of cardiac implants, localization of bacterial vegetations, administered catecholamines, antibiotic therapy, artificial ventilation, surgical treatment, complication and in-hospital mortality. Incidence of cardiac complications in all of BCNIE cases and in 81,3% cases of BCPIE draws attention, but it is not statistically significant difference (p=0,08). There was statistically significant difference in mean BNP blood concentration (3005,17 ng/ml ±2045,2 vs 1013,42 ng/ml ±1087,6; p=0,01), but there were no statistically significant differences in rest of laboratory parameters. BCNIE group has got higher mean BNP blood concentration than BCPIE group. There were no statistically significant differences between these groups in others laboratory parameters, clinical course and administered antibiotic therapy

    Full Text Available This report describes the first documented case of Erysipelothrix rhusiopathiae endocarditis in Latin America. The patient was a 51-years-old male, moderate alcoholic, with a previous history of aortic failure. He was used to fishing and cooking as a hobby and had his left hand wounded by a fish-bone. The disease began with erysipeloid form and developed to septicemia and endocarditis. He was treated with antibiotics and surgery for aortic valve replacement. There are only 46 cases of E. rhusiopathiae endocarditis reported to date. The authors wonder if several other cases might go unreported for lack of microbiological laboratorial diagnosis.

    Infective endocarditis (IE) one-year mortality rates approach 40%. Here, we report two native valve Enterococcus faecalis IE cases in patients successfully treated with telavancin. An 88-year-old with mitral valve endocarditis and a penicillin allergy, initially treated with intravenous vancomycin, was switched to telavancin. A 69-year-old, who previously received amoxicillin and intravenous vancomycin for presumed enterococcal bacteraemia, was diagnosed with dual valve endocarditis for which he received telavancin. Both received six weeks of telavancin. Neither had telavancin-related adverse events, evidence of infection at six months, nor required telavancin dosing adjustments. Documented use of novel treatments for serious enterococcal infections is needed.

    An unusual case of infective endocarditis and concurrent multiple liver abscesses both caused by Streptococcus anginosus in a splenectomised patient is reported. The microorganism is a very rare cause of endocarditis and its presentation with multiple liver abscesses is highly unusual. It was initially misdiagnosed as Streptococcus sanguinis and issues relating to the different clinical presentations of S. anginosus including the rare cases of endocarditis, the role of the patient's splenectomy and problems that may contribute to its potential laboratory misidentifications are discussed. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    We report the case of using a long-term combination of meropenem and amikacin to treat infective endocarditis caused by Enterobacter cloacae resistant to third- and fourth-generation cephalosporins. Multi-drug resistant Gram-negative bacilli, such as the E. cloacae in our study, may become possible pathogens of infective endocarditis. Our experience with this case indicates that long-term use of a combination of β-lactam and aminoglycosides might represent a suitable management option for future infective endocarditis cases due to non-Haemophilus, Actinobacillus, Cardiobacterium, Eikenella, Kingella spp. (HACEK group) Gram-negative bacilli such as ours.

    Full Text Available HACEK endocarditis is often difficult to diagnose given the slow-growing characteristics of the organisms involved. Haemophilus parainfluenzae, one of the HACEK organisms, is an uncommon cause of endocarditis. We describe a case of a previously healthy young man with H parainfluenzae endocarditis that was associated with maxillary sinusitis and severe systemic complications, including septic cerebral emboli and mitral valve perforation. Previously reported cases have also described a predilection for younger people, cardiac valve pathology, and a high prevalence of stroke.

    2014-09-01

    Full Text Available Rothia aeria is an uncommon pathogen mainly associated with endocarditis in case reports. In previous reports, endocarditis by R. aeria was complicated by central nervous system embolization. In the case we report herein, endocarditis by R. aeria was diagnosed after acute self-limited diarrhea. In addition to the common translocation of R. aeria from the oral cavity, we hypothesize the possibility of intestinal translocation. Matrix-assisted laser desorption ionization-time of flight mass spectrometry and genetic sequencing are important tools that can contribute to early and more accurate etiologic diagnosis of severe infections caused by Gram-positive rods.

    Full Text Available Abstract Background Infective endocarditis is rarely caused by Burkholderia cepacia. This infection is known to occur particularly in immunocompromised hosts, intravenous heroin users, and in patients with prosthetic valve replacement. Most patients with Burkholderia cepacia endocarditis usually need surgical treatment in addition to antimicrobial treatment. Case Presentation Here, we report the case of a patient who developed Burkholderia cepacia-induced native valve endocarditis with consequent cerebral involvement without any predisposing factors; she was successfully treated by antimicrobial agents only. Conclusion In this report, we also present literature review of relevant cases.

A dilated fundoscopic exam, Humphrey visual field test, transthoracic echocardiogram, abdominal computed tomography (CT, and blood cultures were all performed.Results: A dilated fundoscopic exam revealed temporal segmental optic disc pallor on the left, and Humphrey visual field testing demonstrated a dense left cecocentral scotoma. When the patient developed fever (103.9°F and palpitations, transthoracic echocardiogram revealed valvular vegetations, and contrast CT of the abdomen revealed an abscess in the dome of the liver likely due to an infectious thrombus. Blood cultures grew viridians group streptococci in three separate peripheral collections.Conclusion: This case illustrates that a sudden cecocentral scotoma may be the initial manifestation of SBE.

    Bacillus cereus is a ubiquitous telluric organism. B. cereus endocarditis is a rare condition seen mostly in prosthetic heart valves and among intravenous drug users. We report a new case of a patient without risk factors and with a good clinical outcome not requiring valve replacement. In October 2014, a 50-year-old woman was referred to the dermatology department of Lille University Hospital for lower-limb wounds developing 6 months earlier. She presented fever without clinical signs of infection, except for the lower-limbs wounds. Blood cultures revealed the presence of B. cereus. Transesophageal echocardiography was performed and revealed two foci of aortic valve vegetation with a diameter of 5mm. After bacterial sensitivity testing, rifampicin and levofloxacin treatment was given for six weeks, with complete remission. A skin graft was performed and good improvement was seen. Nineteen cases of B. cereus endocarditis have been described previously, only one of which was without risk factors. We described a case of complete remission after a 6-week course of antibiotics. Our case demonstrates that BC should not be considered as a blood culture contamination, and that treatment may be complex due to antibiotic resistance. Copyright © 2016 Elsevier Masson SAS.

    To define the clinical presentation of aerococcal infective endocarditis (IE) and the prevalence of synergy between penicillin and gentamicin on aerococcal isolates. Cases of aerococcal IE between 2002 and 2014 were identified in the Swedish Registry of Infective Endocarditis (SRIE). MALDI-TOF MS was used to confirm species determination. The medical records were analysed and compared to cases reported to the SRIE caused by other pathogens. Sixteen cases of aerococcal IE, fourteen with Aerococcus urinae and two with Aerococcus sanguinicola, were confirmed. Etest-based methods and time-kill experiments suggested synergy between penicillin and gentamicin towards seven of fifteen isolates. The patients with aerococcal IE were significantly older than those with streptococci or Staphylococcus aureus IE. Most of the patients had underlying urinary tract diseases or symptoms suggesting a urinary tract focus of the infection. Seven patients with aerococcal IE presented with severe sepsis but ICU treatment was needed only in one patient and there was no fatality. Valve exchange surgery was needed in four patients and embolization was seen in three patients. This report is the largest on aerococcal IE and suggests that the prognosis is relatively favourable despite the fact that the patients are old and have significant comorbidities.

    Thirty-five year-old Amadeus Mozart died in Vienna after an acute illness that lasted only 15 days but no consensus has been reached on the cause of his death. From many letters written by his farther it is almost certain that he experienced at least three episodes of acute rheumatic fever attack in his childhood, and a relapse of rheumatic fever was suggested to have killed Mozart, although death from acute rheumatic fever is very rare in adults. His last illness was characterized by high fever, massive edema, vomiting and skin rash. His last illness can be explained by infectious endocarditis and heart failure. During his last hours, he was given phlebotomy, possibly for the third time in two weeks, and soon after he became unconscious and died. As such, phlebotomy performed on a man dehydrated by high fever and vomiting may have caused systemic shock. In summary, Mozart probably died from chronic rheumatic heart disease complicated by infective endocarditis and heart failure, and repeated phlebotomy-induced hypovolemic shock.

    Full Text Available Abstract Background There are few reports in the literature of invasive infection caused by Brevundimonas vesicularis in patients without immunosuppression or other predisposing factors. The choice of antimicrobial therapy for bacteremia caused by the pathogen requires more case experience to be determined. Case presentation The case of a 40-year-old previously healthy man with subacute endocarditis proposed to be contributed from an occult dental abscess is described. The infection was found to be caused by B. vesicularis on blood culture results. The patient recovered without sequelae after treatment with ceftriaxone followed by subsequent ciprofloxacin therapy owing to an allergic reaction to ceftriaxone and treatment failure with ampicillin/sulbactam. Conclusion To our knowledge, this is the first report of B. vesicularis as a cause of infective endocarditis. According to an overview of the literature and our experience, we suggest that third-generation cephalosporins, piperacillin/tazobactam, and ciprofloxacin are effective in treating invasive B. vesicularis infections, while the efficacy of ampicillin-sulbactam needs further evaluation.

  1. Nuclear Medicine in Diagnosis of Prosthetic Valve Endocarditis: An Update

    Science.gov (United States)

    Musso, Maria; Petrosillo, Nicola

    2015-01-01

    Over the past decades cardiovascular disease management has been substantially improved by the increasing introduction of medical devices as prosthetic valves. The yearly rate of infective endocarditis (IE) in patient with a prosthetic valve is approximately 3 cases per 1,000 patients. The fatality rate of prosthetic valve endocarditis (PVE) remains stable over the years, in part due to the aging of the population. The diagnostic value of echocardiography in diagnosis is operator-dependent and its sensitivity can decrease in presence of intracardiac devices and valvular prosthesis. The modified Duke criteria are considered the gold standard for diagnosing IE; their sensibility is 80%, but in clinical practice their diagnostic accuracy in PVE is lower, resulting inconclusively in nearly 30% of cases. In the last years, these new imaging modalities have gained an increasing attention because they make it possible to diagnose an IE earlier than the structural alterations occurring. Several studies have been conducted in order to assess the diagnostic accuracy of various nuclear medicine techniques in diagnosis of PVE. We performed a review of the literature to assess the available evidence on the role of nuclear medicine techniques in the diagnosis of PVE. PMID:25695043

Métodos: Foram identificados os óbitos com menção de sepse pulmonar independentemente da causa básica. Aos médicos atestantes, aplicou-se questionário medindo a associação entre sepse pulmonar e pneumonia. O registro de pneumonia nos prontuários dos óbitos com menção de sepse pulmonar e sem menção de pneumonia na DO foi investigado. Foi descrito o perfil de mortalidade após a inclusão simulada do código de pneumonia nas declarações com sepse pulmonar. Resultados: Sepse pulmonar correspondeu a 30,9% das menções de sepse e a menção de pneumonia estava ausente em 51,3% dessas declarações. Pneumonia constava em 82,8% da amostra de prontuários investigados. Dos médicos entrevistados, 93,3% relataram pneumonia como a mais frequente causa de sepse pulmonar. A simulação revelou que a inclusão da pneumonia alterou a causa básica de 7,8% dos óbitos com menção de sepse e 2,4% de todos os óbitos, independentemente da causa original. Conclusão: Sepse pulmonar está associada à pneumonia e a simples inclusão do código de pneumonia nas declarações de óbito com menção de sepse pulmonar impactaria o perfil de mortalidade, apontando necessidade de aprimoramento das regras de codificação na Classificação Internacional de Doenças (CID-10.

    Full Text Available Transcatheter aortic valve implantation (TAVI was introduced as an alternative treatment for patients with severe symptomatic aortic stenosis for whom surgery would be high-risk. Prosthetic aortic valve endocarditis is a serious complication of surgical AVR (SAVR with high morbidity and mortality. According to recent cases, post-TAVI prosthetic valve endocarditis (PVE seems to occur very rarely. We present the case of a 75-year-old woman who underwent TAVI (Edwards Saphien XT with an uneventful postoperative stay. She was diagnosed with endocarditis using three dimensional (3D echocardiography on the TAVI device 7 months later and she subsequently underwent surgical aortic valve replacement. Little experience of the interpretation of transoesophageal echocardiography (TEE and the clinical course and effectiveness of treatment strategies in post-TAVI endocarditis exists. We report a case of PVE in a TAVI patient which was diagnosed with three-dimensional transoesophageal echocardiography (3DTEE.

    A case of severe endocarditis, with complications of multiple infarction, meningitis, and ruptured mitral chordae tendineae, caused by Streptococcus agalactiae in a healthy man, is reported. Emergency cardiovascular surgery was performed on the day of admission. Infective endocarditis caused by S. agalactiae is very rare, particularly in a healthy adult. In addition, microbiological analysis revealed that S. agalactiae of sequence type (ST) 19, which belongs to serotype III, was present in the patient's vegetation, mitral valve, and blood culture. It was therefore concluded that the endocarditis was caused by ST19, which has been reported as a non-invasive type of S. agalactiae.

    Echocardiography, transthoracic and transoesophageal, plays a key role in the diagnosis and prognosis assessment of patients with infective endocarditis. It constitutes a major Duke criterion and is pivotal in treatment guiding. Seven echocardiographic findings are major criteria in the diagnosis of infective endocarditis (IE) (vegetation, abscess, pseudoaneurysm, fistulae, new dehiscence of a prosthetic valve, perforation and valve aneurysm). Echocardiography must be performed as soon as endocarditis is suspected. Transoesophageal echocardiography should be done in most cases of left-sided endocarditis to better define the anatomic lesions and to rule out local complications. Transoesophageal echocardiography is not necessary in isolated right-sided native valve IE with good quality transthoracic examination and unequivocal echocardiographic findings. Echocardiography is a very useful tool to assess the prognosis of patients with IE at any time during the course of the disease. Echocardiographic predictors of poor outcome include presence of periannular complications, prosthetic dysfunction, low left ventricular ejection fraction, pulmonary hypertension and very large vegetations.

    Infective endocarditis (IE) is a severe disease with high mortality and morbidity. Prosthetic valve endocarditis is a life-threatening complication which can occur in less than 10% of patients with valve prosthesis. A fungal etiology of IE is rare and accounts for only 2-4% of all case of endocarditis, but is associated with a higher mortality and morbidity. Herein is reported the first case of fungal endocarditis of aortic valve prosthesis due to Aspergillus oryzae in a 67-year-old caucasian man who nine years previously underwent mitral and aortic valve replacement with mechanical prostheses, and tricuspid annuloplasty for acute IE due to Enterococcus spp. Seven months previously, the patient also underwent a redo cardiac procedure to replace a mitral valve prosthesis with a new mechanical device due to a leakage. Aspergillus oryzae showed impressive growth with strong and unexpected virulence in both local and systemic settings.

    Lactobacillus acidophilus rarely causes bacterial endocarditis, because it usually resides in the mucosa of the vagina, gastrointestinal tract, and oropharynx. Moreover, sinus of Valsalva aneurysms are rare cardiac anomalies, either acquired or congenital. We present the case of a middle-aged man whose bacterial endocarditis, caused by Lactobacillus acidophilus, led to an aneurysmal rupture of the sinus of Valsalva into the right ventricular outflow tract. The patient underwent successful surgical repair, despite numerous complications and sequelae.

    Early detection of infectious endocarditis is challenging. For diagnosing infectious endocarditis, the revised Duke criteria are the gold standard. Evidence of endocardial involvement on echocardiography is a major criterion, but sensitivity and specificity of echocardiography are not optimal. Here we investigated the utility of {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography and computed tomography (PET/CT) to diagnose infectious endocarditis in patients with gram-positive bacteraemia. Seventy-two patients with gram-positive bacteraemia were prospectively included. Patients with a positive blood culture growing Staphylococcus aureus, Streptococcus species or Enterococcus species were eligible when a risk factor for developing metastatic infectious foci was present. Infectious endocarditis was defined according to the revised Duke criteria. All patients underwent {sup 18}F-FDG PET/CT and echocardiography. {sup 18}F-FDG uptake in or around the heart valves was evaluated independently by two nuclear medicine physicians. Sensitivity for diagnosing infectious endocarditis with {sup 18}F-FDG PET/CT was 39 % and specificity was 93 %. The positive predictive value was 64 % and negative predictive value was 82 %. The mortality rate in patients without infectious endocarditis and without increased {sup 18}F-FDG uptake in or around the heart valves was 18 %, and in patients without infectious endocarditis but with high {sup 18}F-FDG uptake in or around the heart valves the mortality rate was 50 % (p = 0.181). {sup 18}F-FDG PET/CT is currently not sufficiently adequate for the diagnosis of infectious endocarditis because of its low sensitivity. Improvements such as patient preparation with low carbohydrate-fat allowed diet and technical advances in the newest PET/CT scanners may increase sensitivity in future studies. (orig.)

    2014-01-01

    Background One third of patients with infective endocarditis will require operative intervention. Given the superiority of valve repair over valve replacement in many indications other than endocarditis, there has been increasing interest and an increasing number of reports of excellent results of valve repair in acute infective endocarditis. The theoretically ideal material for valve repair in this setting is non-permanent, “vanishing” material, not at risk of seeding or colonization. The goal of this contribution is to review currently available data on biodegradable materials for valve repair in infective endocarditis. Discussion Rigorous electronic and manual literature searches were conducted to identify reports of biodegradable materials for valve repair in infective endocarditis. Articles were identified in electronic database searches of Medline, Embase and the Cochrane Library, using a predetermined search strategy. 49 manuscripts were included in the review. Prosthetic materials needed for valve repair can be summarized into annuloplasty rings to remodel the mitral or tricuspid annulus, and patch materials to replace resected valvar tissue. The commercially available biodegradable annuloplasty ring has shown interesting clinical results in a single-center experience; however further data is required for validation and longer follow-up. Unmodified extra-cellular matrix patches, such as small intestinal submucosa, have had promising initial experimental and clinical results in non-infected valve repair, although in valve repair for endocarditis has been reported in only one patient, and concerns have been raised regarding their mechanical stability in an infected field. Summary These evolving biodegradable devices offer the potential for valve repair with degradable materials replaced with autologous tissue, which could further improve the results of valve repair for infective endocarditis.

    We aimed to compare imaging findings of infective endocarditis between computed tomography (CT) and transoesophageal echocardiography (TEE) using surgical inspection as a reference standard. Forty-nine patients (aged 54 ± 17 years, 69% men) who underwent pre-operative CT and TEE for infective endocarditis were included. Twelve of these patients had prosthetic valve endocarditis. Imaging findings of infective endocarditis were classified as vegetation, leaflet perforation, abscess/pseudoaneurysm, and paravalvular leakage. Diagnostic performances of CT and TEE were evaluated using surgical inspection as a reference standard. Interobserver agreements for CT findings were obtained using Cohen's κ test. The detection rates of infective endocarditis per patient with CT and TEE were 93.9% (46/49) and 95.9% (47/49), respectively. In per-imaging analysis, the sensitivities of CT and TEE were not significantly different for both native and prosthetic valve infective endocarditis (sensitivity: vegetation, 100% in TEE and 90.9% in CT; leaflet perforation, 87.5% in TEE and 50.0% in CT; abscess/pseudoaneurysm, 40.0% in TEE and 60.0% in CT; paravalvular leakage, 100% in TEE and 50.0% in CT). Interobserver agreements for CT findings were substantial or excellent (0.79-0.88). Cardiac CT can accurately demonstrate infective endocarditis in pre-operative patients with a similar diagnostic accuracy to TEE. The interobserver agreements for the CT findings of infective endocarditis were excellent. Published on behalf of the European Society of Cardiology. All rights reserved. © The Author 2017.

    The main clinical manifestations of Whipple's disease are weight loss, arthropathy, diarrhea and abdominal pain. Cardiac involvement is frequently described. However, endocarditis is rare and is not usually the initial presentation of the disease. To the best of our knowledge, this is the first reported case of a patient with Tropheryma whipplei tricuspid endocarditis without any other valve involved and not presenting signs of arthralgia and abdominal involvement. We report a case of a 50-year-old Caucasian man with tricuspid endocarditis caused by Tropheryma whipplei, showing signs of severe shock and an absence of other more classic clinical signs of Whipple's disease, such as arthralgia, abdominal pain and diarrhea. Tropheryma whipplei was documented by polymerase chain reaction of the blood and pleural fluid. The infection was treated with a combined treatment of doxycycline, hydroxychloroquine and sulfamethoxazole-trimethoprim for one year. Tropheryma whipplei infectious endocarditis should always be considered when facing a blood-culture negative endocarditis particularly in right-sided valves. Although not standardized yet, treatment of Tropheryma whipplei endocarditis should probably include a bactericidal antibiotic (such as doxycycline) and should be given over a prolonged period of time (a minimum of one year).

    2001-01-01

    In Streptococcus sanguinis (sanguis) induced experimental endocarditis, we sought evidence that the development of aortic valvular vegetation depends on the availability of fibrin. Endocarditis was induced in New Zealand white rabbits by catheter placement into the left ventricle and inoculation of the bacteria. Fibrin was localized in the developing vegetation with 99mTechnetium (Tc)-labeled anti-fibrin antibody one or three days later. When rabbit anti-fibrin antibody was given intravenously on day 1, the mass of aortic valvular vegetation was significantly reduced at day 3; infusion of non-specific rabbit IgG showed no effect. The 99mTc-labeled anti-fibrin antibody also labeled kidneys that showed macroscopic subcapsular hemorrhage. To learn if the deposition of fibrin in the kidneys was a consequence of endocarditis required a comparison of farm-bred and specific pathogen-free rabbits before and after the induction of endocarditis. Before induction, the kidneys of farm-bred rabbits were labeled, but specific pathogen-free rabbits were free of labeling and signs of macroscopic hemorrhage. After 3 days of endocarditis, kidneys of 10 of 14 specific pathogen-free rabbits labeled with 99mTc-labeled anti-fibrin antibody and showed hemorrhage. Kidney lesions were suggested to be a frequent sequellae of S. sanguinis infective endocarditis. For the first time, fibrin was shown to be required for the continued development of aortic valvular vegetations.

  15. Infective endocarditis causing mitral valve stenosis - a rare but deadly complication: a case report.

    Hart, Michael A; Shroff, Gautam R

    2017-02-17

    Infective endocarditis rarely causes mitral valve stenosis. When present, it has the potential to cause severe hemodynamic decompensation and death. There are only 15 reported cases in the literature of mitral prosthetic valve bacterial endocarditis causing stenosis by obstruction. This case is even more unusual due to the mechanism by which functional mitral stenosis occurred. We report a case of a 23-year-old white woman with a history of intravenous drug abuse who presented with acute heart failure. Transthoracic echocardiography failed to show valvular vegetation, but high clinical suspicion led to transesophageal imaging that demonstrated infiltrative prosthetic valve endocarditis causing severe mitral stenosis. Despite extensive efforts from a multidisciplinary team, she died as a result of her critical illness. The discussion of this case highlights endocarditis physiology, the notable absence of stenosis in modified Duke criteria, and the utility of transesophageal echocardiography in clinching a diagnosis. It advances our knowledge of how endocarditis manifests, and serves as a valuable lesson for clinicians treating similar patients who present with stenosis but no regurgitation on transthoracic imaging, as a decision to forego a transesophageal echocardiography could cause this serious complication of endocarditis to be missed.

    The search for the presence of vegetations in patients with suspected infective endocarditis is a major indication for trans-esophageal echocardiographic (TEE) examinations. Advances in harmonic imaging and ongoing improvement in modern echocardiographic systems allow adequate quality of diagnostic images in most patients. To investigate whether TEE examinations are always necessary for the assessment of patients with suspected infective endocarditis. During 2012-2014 230 trans-thoracic echo (TTE) exams in patients with suspected infective endocarditis were performed at our center. Demographic, epidemiological, clinical and echocardiographic data were collected and analyzed, and the final clinical diagnosis and outcome were determined. Of 230 patients, 24 had definite infective endocarditis by clinical assessment. TEE examination was undertaken in 76 of the 230 patients based on the clinical decision of the attending physician. All TTE exams were classified as: (i) positive, i.e., vegetations present; (ii) clearly negative; or (iii) non-conclusive. Of the 92 with clearly negative TTE exams, 20 underwent TEE and all were negative. All clearly negative patients had native valves, adequate quality images, and in all 92 the final diagnosis was not infective endocarditis. Thus, the negative predictive value of a clearly negative TTE examination was 100%. In patients with native cardiac valves referred for evaluation for infective endocarditis, an adequate quality TTE with clearly negative examination may be sufficient for the diagnosis.

    Limited data exist on clinical characteristics and outcomes of patients who had infective endocarditis after undergoing transcatheter aortic valve replacement (TAVR). To determine the associated factors, clinical characteristics, and outcomes of patients who had infective endocarditis after TAVR. The Infectious Endocarditis after TAVR International Registry included patients with definite infective endocarditis after TAVR from 47 centers from Europe, North America, and South America between June 2005 and October 2015. Transcatheter aortic valve replacement for incidence of infective endocarditis and infective endocarditis for in-hospital mortality. Infective endocarditis and in-hospital mortality after infective endocarditis. A total of 250 cases of infective endocarditis occurred in 20 006 patients after TAVR (incidence, 1.1% per person-year; 95% CI, 1.1%-1.4%; median age, 80 years; 64% men). Median time from TAVR to infective endocarditis was 5.3 months (interquartile range [IQR], 1.5-13.4 months). The characteristics associated with higher risk of progressing to infective endocarditis after TAVR was younger age (78.9 years vs 81.8 years; hazard ratio [HR], 0.97 per year; 95% CI, 0.94-0.99), male sex (62.0% vs 49.7%; HR, 1.69; 95% CI, 1.13-2.52), diabetes mellitus (41.7% vs 30.0%; HR, 1.52; 95% CI, 1.02-2.29), and moderate to severe aortic regurgitation (22.4% vs 14.7%; HR, 2.05; 95% CI, 1.28-3.28). Health care-associated infective endocarditis was present in 52.8% (95% CI, 46.6%-59.0%) of patients. Enterococci species and Staphylococcus aureus were the most frequently isolated microorganisms (24.6%; 95% CI, 19.1%-30.1% and 23.3%; 95% CI, 17.9%-28.7%, respectively). The in-hospital mortality rate was 36% (95% CI, 30.0%-41.9%; 90 deaths; 160 survivors), and surgery was performed in 14.8% (95% CI, 10.4%-19.2%) of patients during the infective endocarditis episode. In-hospital mortality was associated with a higher logistic EuroSCORE (23.1% vs 18.6%; odds ratio

    The diagnosis of prosthetic valve endocarditis is challenging. The gold standard for prosthetic valve endocarditis diagnosis is trans-esophageal echocardiography. However, trans-esophageal echocardiography may result in negative findings or yield images difficult to differentiate from thrombus in patients with prosthetic valve endocarditis. Combined computed tomography and fluorodeoxyglucose positron emission tomography is a potentially promising diagnostic tool for several infectious conditions and it has also been employed in patients with prosthetic valve endocarditis but data are still scant. We reviewed the charts of 6 patients with prosthetic aortic valves evaluated for suspicion of prosthetic valve endocarditis, at two different hospital, over a 3-year period. We found 3 patients with early-onset PVE cases and blood cultures yielding Pseudomonas aeruginosa, Staphylococcus epidermidis and Staphylococcus lugdunensis, respectively; and 3 late-onset cases in the remaining 3 patients with isolation in the blood of Streptococcus bovis, Candida albicans and P. aeruginosa, respectively. Initial trans-esophageal echocardiography was negative in all the patients, while fluorodeoxyglucose positron emission tomography showed images suspicious for prosthetic valve endocarditis. In 4 out of 6 patients valve replacement was done with histology confirming the prosthetic valve endocarditis diagnosis. After an adequate course of antibiotic therapy fluorodeoxyglucose positron emission tomography showed resolution of prosthetic valve endocarditis in all the patients. Our experience confirms the potential role of fluoroseoxyglucose positron emission tomography in the diagnosis and follow-up of prosthetic valve endocarditis.

    Full Text Available Cardiobacterium hominis, a member of the HACEK group of organisms, is an uncommon but important cause of subacute bacterial endocarditis. First-line therapy is a third-generation cephalosporin due to rare beta-lactamase production. The authors report a case involving endovascular infection due to C hominis that initially tested resistant to third-generation cephalosporins using an antibiotic gradient strip susceptibility method (nitrocephin negative, but later proved to be susceptible using broth microdilution reference methods (a ‘major’ error. There are limited studies to guide susceptibility testing and interpretive breakpoints for C hominis in the medical literature, and the present case illustrates some of the issues that may arise when performing susceptibility testing for fastidious organisms in the clinical microbiology laboratory.

    2016-10-01

    Our objective is to present the case of an uncommon but probably under-recognized cause of stroke: Non-bacterial thrombotic endocarditis (NBTE). A 59-year-old man presented to our hospital with multiple bihemispheric infarcts despite taking rivaroxaban for pulmonary emboli diagnosed 2 weeks earlier. The patient's symptoms progressed quickly and he died within a week of his initial presentation despite attempts at neuroradiologically guided clot retrieval and early recognition and treatment of disseminated intravascular coagulation. On postmortem examination it was discovered that he had an undiagnosed squamous cell adenocarcinoma of the lung and NBTE. NBTE is difficult to diagnose and difficult to treat. It is associated with a mortality rate and is often not diagnosed until autopsy. However there are case reports in the literature where NBTE has been successfully treated. Early recognition and prompt treatment of the underlying disease process is the essential first step. Copyright © 2016 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Infective endocarditis (IE) is a disease with high morbidity and a mortality rate of 9-30%, even with appropriate diagnosis and therapy. Septic emboli, caused by IE, can affect any organ or tissue in the body with an arterial supply and occur in 12-40% of IE cases. The most common extra-cardiac organ system involved in IE is the central nervous system. Other organs frequently involved are the lungs (especially in right-sided IE), spleen, kidneys, liver, and the musculoskeletal system. In addition, the arterial system itself is susceptible to the development of potentially fatal mycotic aneurysms. As extra-cardiac complications often antedate the clinical diagnosis of IE, it is important that the diagnosis is suggested when characteristic findings are encountered during imaging. In addition, imaging is often used to monitor the extent of complications in patients with a known diagnosis of IE. (orig.)

    Background: Infective endocarditis (IE) has been increasingly reported, however, little is available regarding recent development of right-sided IE. Methods: Right-sided IE was comprehensively analyzed based on recent 5⅓-year literature. Results: Portal of entry, implanted foreign material, and repaired congenital heart defects were the main predisposing risk factors. Vegetation size on the right-sided valves was much smaller than those beyond the valves. Multiple logistic regression analysis revealed that predisposing risk factors, and vegetation size and locations were independent predictive risks of patients’ survival. Conclusions: Changes of right-sided IE in the past 5⅓ years included younger patient age, and increased vegetation size, but still prominent Staphylococcus aureus infections. Complication spectrum has changed into more valve insufficiency, more embolic events, reduced abscess formation, and considerably decreased valve perforations. With effective antibiotic regimens, prognoses of the patients seemed to be better than before. PMID:24482708

    Full Text Available We report a case of a 51-year-old diabetic male who presented with a complaint of intermittent chills and fever that he had experienced for 10 days. No obvious respiratory tract, genitourinary tract, gastrointestinal tract, or skin lesions were observed. Blood culture data were positive for group B β-streptococcus. Transthoracic and transesophageal echocardiography revealed vegetation in the anterior leaflet of the mitral valve. The patient was diagnosed with infective endocarditis (IE and prescribed a parenteral antibiotic. Three days after admission, the patient complained of progressively blurred vision. Slit lamp examination found fine keratic precipitates and aqueous cells in the anterior chambers in both eyes, implying that the patient had uveitis. He was then prescribed a topical steroid for 4 months, and his vision improved gradually. This case is an important reminder that uveitis, not only endophthalmitis, can occur with IE. Treatment for one condition, if misapplied, may worsen the other.

    Infective endocarditis (IE) is a difficult-to-diagnose pathology, since its manifestation in patients is highly variable. In this work, it was proposed a semiautomatic algorithm based on SPECT images digital processing for the detection of IE using a CT images volume as a spatial reference. The heart/lung rate was calculated using the SPECT images information. There were no statistically significant differences between the heart/lung rates values of a group of patients diagnosed with IE (2.62+/-0.47) and a group of healthy or control subjects (2.84+/-0.68). However, it is necessary to increase the study sample of both the individuals diagnosed with IE and the control group subjects, as well as to improve the images quality.

    Systemic embolism, especially septic embolism, is a severe complication of infective endocarditis (IE). However, concurrent embolism to the brain, coronary arteries, and spleen is very rare. Because of the risk of hemorrhage or visceral rupture, anticoagulants are recommended only if an indication is present, e.g. prosthetic valve. Antiplatelet therapy in IE is controversial, but theoretically, this therapy has the potential to prevent and treat thrombosis and embolism in IE. Unfortunately, clinical trial results have been inconclusive. We describe a previously healthy 50-year-old man who presented with dysarthria secondary to bacterial endocarditis with multiple cerebral, coronary, splenic, and peripheral emboli; antibiotic therapy contributed to the multiple emboli. Emergency splenectomy was performed, with subsequent mitral valve repair. Pathological examination confirmed mucoid degeneration and mitral valve prolapse (Barlow's disease) as the underlying etiology of the endocardial lesion. Continuous antibiotics were prescribed, postoperatively. Transthoracic echocardiography at 1.5, 3, and 6 months after the onset of his illness showed no severe regurgitation, and there was no respiratory distress, fever, or lethargy during follow-up. Although antibiotic use in IE carries a risk of septic embolism, these drugs have bactericidal and antithrombotic benefits. It is important to consider that negative blood culture and symptom resolution do not confirm complete elimination of bacteria. However, vegetation size and Staphylococcus aureus infection accurately predict embolization. It is also important to consider that bacteria can be segregated from the microbicide when embedded in platelets and fibrin. Therefore, antimicrobial therapy with concurrent antiplatelet therapy should be considered carefully.

    Infective endocarditis and kidney infections are serious complications of Staphylococcus aureus sepsis. We investigated the role of superantigens (SAgs) in the development of lethal sepsis, infective endocarditis, and kidney infections. SAgs cause toxic shock syndrome, but it is unclear if SAgs contribute to infective endocarditis and kidney infections secondary to sepsis. We show in the methicillin-resistant S. aureus strain MW2 that lethal sepsis, infective endocarditis, and kidney infections in rabbits are critically dependent on high-level SAgs. In contrast, the isogenic strain lacking staphylococcal enterotoxin C (SEC), the major SAg in this strain, is attenuated in virulence, while complementation restores disease production. SAgs' role in infective endocarditis appears to be both superantigenicity and direct endothelial cell stimulation. Maintenance of elevated blood pressure by fluid therapy significantly protects from infective endocarditis, possibly through preventing bacterial accumulation on valves and increased SAg elimination. These data should facilitate better methods to manage these serious illnesses. The Centers for Disease Control and Prevention reported in 2007 that Staphylococcus aureus is the most significant cause of serious infectious diseases in the United States (R. M. Klevens, M. A. Morrison, J. Nadle, S. Petit, K. Gershman, et al., JAMA 298:1763-1771, 2007). Among these infections are sepsis, infective endocarditis, and acute kidney injury. Infective endocarditis occurs in 30 to 60% of patients with S. aureus bacteremia and carries a mortality rate of 40 to 50%. Over the past decades, infective endocarditis outcomes have not improved, and infection rates are steadily increasing (D. H. Bor, S. Woolhandler, R. Nardin, J. Brusch, D. U. Himmelstein, PLoS One 8:e60033, 2013). There is little understanding of the S. aureus virulence factors that are key for infective endocarditis development and kidney abscess formation. We demonstrate that

    The aim of this study was to compare the etiology, clinical course, selected diagnostic methods and efficacy of the treatment used in patients with infective endocarditis (IE) in the nineteen eighties and nineties. The study group comprised 300 patients with infective endocarditis hospitalized in the Institute of Cardiology in Warsaw in the following years: from 1982 to 1987 (150 patients: 75 successive patients with IE on the prosthetic valve and 75 successive patients with IE on the native valve), as well as from 1990 to 2003 (150 patients: 75 successive patients with IE on the prosthetic valve and 75 successive patients with IE on the native valve). In the nineties, immunological symptoms, embolism formation and progressive heart failure were diagnosed decidedly more frequently. Early prosthetic valve endocarditis (PVE) (up to 60 days after operation) occurred significantly more frequently in the eighties. The quantity of negative blood cultures in PVE has not decreased, it is still observed in over 20% of cases. For 20 years the etiology of PVE has remained the same, the dominant pathogen remains Staphylococcus. The frequency of PVE caused by Streptococci has markedly reduced. In both the decades analyzed the etiology of native valve endocarditis (NVE) was similar. In the eighties Streptococcus was predominant. In successive years the number of infections caused by Staphylococci was the same as that caused by Streptococci. The incidence of early PVE decreased in the nineties. More patients were treated surgically with lesser peri-operative mortality. A lower incidence of infective endocarditis on prosthetic valves caused by streptococci may signify better prophylaxis against infective endocarditis. Infective endocarditis with sterile blood cultures continues to occur frequently.

    Background and aims. Dental procedures injuring oral tissues may induce bacterial release to blood stream that can cause infective endocarditis in susceptible patients. The aim of this study was to determine the level of knowledge of general dental practitioners (GDPs in Tabriz, Northwest of Iran, regarding endocarditis prophylaxis in cardiac patients receiving dental treatments.

    Materials and methods. This was a cross-sectional, descriptive, analytical study that included 150 GDPs. All practitioners were given a self-administered questionnaire which consisted of three parts assessing their knowledge of cardiac diseases requiring prophylaxis, dental procedures requiring prophylaxis, and antibiotic regimen for endocarditis prophylaxis. Statistical analysis of data was carried out using independent t-test, one-way ANOVA and chi-square test.

    Results. The level of knowledge among GDPs in three areas of cardiac diseases requiring prophylaxis, dental procedures requiring prophylaxis, and antibiotic regimen for endocarditis prophylaxis were 63.7%, 66.8% and 47.7%, respectively. Their overall level of knowledge regarding endocarditis prophylaxis was 59%. Association of the level of knowledge with age and practice period was statistically significant (P < 0.05. However, the level of knowledge was not significantly associated with gender or university of graduation in either of three areas evaluated (P > 0.05.

    Conclusion. According to our results, the knowledge of endocarditis prophylaxis among GDPs in Tabriz was in a moderate level. Regarding the importance of endocarditis prophylaxis in susceptible patients, it should be more emphasized in the curriculum of dental schools and continuing dental education programs.

    Conventional diagnosis of infective endocarditis (IE) is based mainly on culture-dependent methods that may fail because of antibiotic therapy or fastidious microorganisms. We aimed to evaluate the added values of serological and molecular methods for diagnosis of infective endocarditis. One hundred and fifty-six cases of suspected endocarditis were enrolled in the study. For each patient, three sets of blood culture were withdrawn and serum sample was collected for Brucella, Bartonella and Coxiella burnetii antibody testing. Galactomannan antigen was added if fungal endocarditis was suspected. Broad range PCR targeting bacterial and fungal pathogens were done on blood culture bottles followed by sequencing. Culture and molecular studies were done on excised valve tissue when available. One hundred and thirty-two cases were diagnosed as definite IE. Causative organisms were detected by blood cultures in 40 (30.3 %) of cases. Blood culture-negative endocarditis (BCNE) represented 69.7 %. Of these cases, PCR followed by sequencing on blood and valvular tissue could diagnose five cases of Aspergillus flavus. Eleven patients with BCNE (8.3 %) were diagnosed as zoonotic endocarditis by serology and PCR including five cases of Brucella spp, four cases of Bartonella spp and two cases of Coxiella burnetii. PCR detected three cases of Brucella spp and two cases of Bartonella spp, while cases of Coxiella burnetii were PCR negative. The results of all diagnostic tools decreased the percentage of non-identified cases of BCNE from 69.7 to 49.2 %. Our data underline the role of serologic and molecular tools for the diagnosis of blood culture-negative endocarditis.

    Cardiac vegetations result from bacterium–platelet adherence, activation and aggregation, and are associated with increased morbidity and mortality in infective endocarditis. The GPIIb/IIIa and FcγRIIa platelet receptors play a central role in platelet adhesion, activation and aggregation induced by endocarditis pathogens such as Staphylococcus aureus, but the influence of known polymorphisms of these receptors on the pathogenesis of infective endocarditis is unknown. We determined the GPIIIa platelet antigen PlA1/A2 and FcγRIIa H131R genotype of healthy volunteers (n = 160) and patients with infective endocarditis (n = 40), and investigated the influence of these polymorphisms on clinical outcome in infective endocarditis and S. aureus–platelet interactions in vitro. Platelet receptor genotype did not correlate with development of infective endocarditis, vegetation characteristics on echocardiogram or the composite clinical end-point of embolism, heart failure, need for surgery or mortality (P > 0.05 for all), even though patients with the GPIIIa PlA1/A1 genotype had increased in vivo platelet activation (P = 0.001). Furthermore, neither GPIIIa PlA1/A2 nor FcγRIIa H131R genotype influenced S. aureus-induced platelet adhesion, activation or aggregation in vitro (P > 0.05). Taken together, our data suggest that the GPIIIa and FcγRIIa platelet receptor polymorphisms do not influence S. aureus–platelet interactions in vitro or the clinical course of infective endocarditis.

    Infective endocarditis is a serious infection, often resulting from injection drug use. Inpatient treatment regularly focuses on management of infection without attention to the underlying addiction. We aimed to determine the addiction interventions done in patients hospitalized with injection drug use-associated infective endocarditis. This is a retrospective review of patients hospitalized with injection drug use-associated infective endocarditis from January, 2004 through August, 2014 at a large academic tertiary care center in Boston, Massachusetts. For the initial and subsequent admissions, data were collected regarding addiction interventions, including consultation by social work, addiction clinical nurse and psychiatry, documentation of addiction in the discharge summary plan, plan for medication-assisted treatment and naloxone provision. There were 102 patients admitted with injection drug use-associated infective endocarditis, 50 patients (49.0%) were readmitted and 28 (27.5%) patients had ongoing injection drug use at readmission. At initial admission, 86.4% of patients had social work consultation, 23.7% had addiction consultation, and 24.0% had psychiatry consultation. Addiction was mentioned in 55.9% of discharge summary plans, 7.8% of patients had a plan for medication-assisted treatment, and naloxone was never prescribed. Of 102 patients, 26 (25.5%) are deceased. The median age at death was 40.9 years (interquartile range 28.7-48.7). We found that patients hospitalized with injection drug use-associated infective endocarditis had high rates of readmission, recurrent infective endocarditis and death. Despite this, addiction interventions were suboptimal. Improved addiction interventions are imperative in the treatment of injection drug use-associated infective endocarditis.

    Full Text Available The aim – to assess short- and long-term results of aortic root replacement using aortic allografts in patients with prosthetic endocarditis. Materials and methods. Since February 2009 until June 2016 aortic valve and ascending aorta replacement using aortic allografts was performed in 26 patients with prosthetic endocarditis. In 50 % of cases at initial operation aortic valve replacement was performed, in another 50 % of cases – aortic valve and ascending aorta replacement. Echocardiography was performed 10 days, 3, 6 and 12 months, 2, 3 and 5 years after surgery. Analysis of long-term results included all cases of deaths, prosthesis-related complications and recurrence of endocarditis. Results. 30-day mortality was 23.1 %. Extracorporeal membranous oxygenation (ECMO was used only in 5 patients (19.2 %. Four patients were weaned from ECMO. We did not observe any allograft-related complications. During follow-up period there were no cases of reoperation due to structural allograft failure. Relapse of infection occurred in 1 patient (3.8 % four years after the operation and led to lethal outcome. Conclusion. Reoperations using allografts are an effective surgical treatment of prosthetic endocarditis. In majority of cases prosthetic endocarditis was caused by gram-positive cocci (Staphylococcus. In 84.6 % of cases it was associated with destruction of paravalvular structures and abscesses formation. Heart failure was a causative factor of different complications in these patients, which required ECMO in 19.2 % of patients. In 80 % of cases patients were weaned from ECMO. Allografts using for the treatment of prosthetic endocarditis is associated with high resistance to infection and with a significant rate of freedom from recurrence of endocarditis within 3 years after surgery.

    2014-01-01

    Background Embolic events are a major cause of morbidity and mortality in patients with infective endocarditis. We analyzed the database of the prospective cohort study SEI in order to identify factors associated with the occurrence of embolic events and to develop a scoring system for the assessment of the risk of embolism. Methods We retrospectively analyzed 1456 episodes of infective endocarditis from the multicenter study SEI. Predictors of embolism were identified. Risk factors identified at multivariate analysis as predictive of embolism in left-sided endocarditis, were used for the development of a risk score: 1 point was assigned to each risk factor (total risk score range: minimum 0 points; maximum 2 points). Three categories were defined by the score: low (0 points), intermediate (1 point), or high risk (2 points); the probability of embolic events per risk category was calculated for each day on treatment (day 0 through day 30). Results There were 499 episodes of infective endocarditis (34%) that were complicated by ≥ 1 embolic event. Most embolic events occurred early in the clinical course (first week of therapy: 15.5 episodes per 1000 patient days; second week: 3.7 episodes per 1000 patient days). In the total cohort, the factors associated with the occurrence of embolism at multivariate analysis were prosthetic valve localization (odds ratio, 1.84), right-sided endocarditis (odds ratio, 3.93), Staphylococcus aureus etiology (odds ratio, 2.23) and vegetation size ≥ 13 mm (odds ratio, 1.86). In left-sided endocarditis, Staphylococcus aureus etiology (odds ratio, 2.1) and vegetation size ≥ 13 mm (odds ratio, 2.1) were independently associated with embolic events; the 30-day cumulative incidence of embolism varied with risk score category (low risk, 12%; intermediate risk, 25%; high risk, 38%; p endocarditis, a simple scoring system, which combines etiology and vegetation size with time on antimicrobials, might contribute to a

    Gentamicin shows large variations in half-life and volume of distribution (Vd) within and between individuals. Thus, monitoring and accurately predicting serum levels are required to optimize effectiveness and minimize toxicity. Currently, two population pharmacokinetic models are applied for predicting gentamicin doses in adults. For endocarditis patients the optimal model is unknown. We aimed at: 1) creating an optimal model for endocarditis patients; and 2) assessing whether the endocarditis and existing models can accurately predict serum levels. We performed a retrospective observational two-cohort study: one cohort to parameterize the endocarditis model by iterative two-stage Bayesian analysis, and a second cohort to validate and compare all three models. The Akaike Information Criterion and the weighted sum of squares of the residuals divided by the degrees of freedom were used to select the endocarditis model. Median Prediction Error (MDPE) and Median Absolute Prediction Error (MDAPE) were used to test all models with the validation dataset. We built the endocarditis model based on data from the modeling cohort (65 patients) with a fixed 0.277 L/h/70kg metabolic clearance, 0.698 (±0.358) renal clearance as fraction of creatinine clearance, and Vd 0.312 (±0.076) L/kg corrected lean body mass. External validation with data from 14 validation cohort patients showed a similar predictive power of the endocarditis model (MDPE -1.77%, MDAPE 4.68%) as compared to the intensive-care (MDPE -1.33%, MDAPE 4.37%) and standard (MDPE -0.90%, MDAPE 4.82%) models. All models acceptably predicted pharmacokinetic parameters for gentamicin in endocarditis patients. However, these patients appear to have an increased Vd, similar to intensive care patients. Vd mainly determines the height of peak serum levels, which in turn correlate with bactericidal activity. In order to maintain simplicity, we advise to use the existing intensive-care model in clinical practice to avoid

    Objectives Patients with systemic lupus erythematosus are considered vulnerable to infective endocarditis and prophylactic antibiotics are recommended before an invasive dental procedure. However, the evidence is insufficient. This nationwide population-based study evaluated the risk and related factors of infective endocarditis in systemic lupus erythematosus. Methods We identified 12,102 systemic lupus erythematosus patients from the National Health Insurance research-oriented database, and compared the incidence rate of infective endocarditis with that among 48,408 non-systemic lupus erythematosus controls. A Cox multivariable proportional hazards model was employed to evaluate the risk of infective endocarditis in the systemic lupus erythematosus cohort. Results After a mean follow-up of more than six years, the systemic lupus erythematosus cohort had a significantly higher incidence rate of infective endocarditis (42.58 vs 4.32 per 100,000 person-years, incidence rate ratio = 9.86, p endocarditis in systemic lupus erythematosus patients. Conclusions A higher risk of infective endocarditis was observed in systemic lupus erythematosus patients. Risk factors for infective endocarditis in the systemic lupus erythematosus cohort included heart disease, chronic kidney disease, steroid pulse therapy within 30 days, and a recent invasive dental procedure within 30 days.

    Full Text Available Infective endocarditis has different presentations depending on the involvement of valvular and perivalvular structures, and it is associated with high morbidity and mortality. Aortocavitary fistula is a rare complication. We introduce the case of a 48-year-old female with native valve endocarditis, complicated by aortocavitary fistula to the right atrium, and consequently presented with syncope.
