    Abnormal connections between the ascending aortaand the cardiac chambers are rare, especially in thecontext of right-sided infective endocarditis(IE). Trans-thoracic echocardiography(TTE) with color-flow Dop-pler, transesophageal echocardiography(TEE), or bothmay be required for diagnosis. We present the case ofa woman admitted with right-sided heart failure(HF)symptoms. She had a previous history of tricuspid valveIE 30 years ago. TTE and TEE revealed an aorto-rightatrium fistula located just under the non-coronary cuspinto the right atrium at the level of the previously af-fected tricuspid valve. The Patient refused surgery andwas discharged home on HF medications. She has beenstable for the last 3 years. The peculiarity of this caseis the late symptomatic presentation of the aorto-atrialfistula and the unusual association to tricuspid valve IE.

    Infective endocarditis (IE) is the most severe complication in intravenous drug abusers (IVDAs). HIV infection increases the risk of IE in IVDAs too. IE in both population are special tendency to infect the right-sided heart, but unusual infective aortic valve. We report a case of HIV and IVDA patient admitted in hospital due to fever syndrome, with X-ray test normal and the first blood cultures negatives. CD4 count cell 90 mm3. It was impossible doing a transesophageal echocardiography (TEE) and transtoracic echocardiogramma (TTE) only showed a moderate aortic insufficiency with conserved systolic function. Despite using antibiotics, antifungals and highly active antiretroviral therapy, he developed ARDS, and mechanical ventilation should be performed. At that moment, TEE showed an aorto pulmonary fistula due to left-sided IE. Further cultures was undergone and only one blood culture was positive to Staphylococcus aureus. Cardiac surgery was not indicated. The patient died 3 weeks later.

    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.

    Aortic graft fistula is a rare and life-threatening complication after aortic reconstruction. The incidence ranges from 0.5 to 4%, and even if the diagnosis and treatment is appropriate, the results of surgery are poor: mortality rate ranges from 14 to 70%. The optimal method of treatment is still controversial; prosthetic removal and extra-anatomic bypass has been advocated as the standard method, but more recently, because the high mortality rate associated with this procedure, some have prompted to recommend in situ aortic graft replacement as a more successful treatment. Personal experience with incidence (0.7%) outcome and mortality (57%) in 7 patients treated over a period of 6 years (1990-1996) is reported. Results from this group are compared with another group (6 patients) previously treated (1975-1982) for the same pathology. Our results after 10 years, show the same incidence (0.7 vs 0.6%) and an elevated and unchanged mortality (57 vs 66%). Better results in the management of aorto-enteric fistulas could be achieved with the removal of infected infrarenal aortic prosthetic grafts and in situ homografts replacement.

    Full Text Available El transplante pulmonar suele ser la última opción terapéutica para pacientes con insuficiencia respiratoria. A pesar de los muchos avances en inmunología y el manejo de las complicaciones, la mortalidad y morbilidad asociadas a este trasplante son muy superiores a los demás. El rechazo agudo es casi un problema universal en el primer año, mientras que la bronquiolitis obliterante limita la supervivencia a largo plazo. Las infecciones respiratorias también cumplen un papel importante en las complicaciones asociadas al trasplante pulmonar por la constante exposición del injerto al medio exterior. No obstante, los éxitos de esta opción terapéutica que depende fundamentalmente de una correcta selección de donante y receptor, son evidentes, sobre todo en cuanto a calidad de vida se refiere.

    Mycobacterium tuberculosis (TB) is a major cause of death globally. TB is capable of infecting every organ in the body, and the heart is no exception. Tuberculous endocarditis (TBE) was first reported in 1892 and subsequently many other cases have been described, highlighting the significant morbidity and mortality associated with this manifestation of TB. TBE usually presents with miliary tuberculosis and most early cases were diagnosed on autopsy. With increasing application of prosthetic valve replacements in the treatment of infective endocarditis (IE), TB infections have begun to affect these as well as native valves. With the introduction of TB culture methods and drug therapy, the prognosis has improved. HIV and drug resistance are likely to make the management of TBE more difficult in the future. Large scale studies, both prospective and retrospective, are required to ascertain the true incidence of TBE whilst development of novel anti-TB therapy is also required to combat resistance. We present the first extensive literature review on TBE in over 75 years.

    Endocarditis is an important, although less common, cause of cerebral embolism. All forms of endocarditis share an initial common pathophysiologic pathway, best illustrated by the non-bacterial thrombotic form, but also a final potential for embolization. Stroke associated with endocarditis has signifficant mortality and morbidity rates, especially due to the frequent concomitant multiple sites of brain embolization. In this article we aim to briefly review endocarditis with a focus on stroke as a complication, while also presenting case correlates from our department.

    A fatal case of endocarditis due to Listeria monocytogenes is reported. Case reports of endocarditis due to this organism are rare but indicate a higher mortality than with many other causes of bacterial endocarditis. The size of the problem may be underestimated because the organism has a "diphtheroid' appearance and may be incorrectly dismissed as a contaminant.

    The epidemiology of infective endocarditis is changing due to a number of factors, including more frequent and varied antibiotic use, the emergence of resistant microorganisms, and an increase in the implantation of cardiovascular devices. This review outlines and consolidates the most recent guidelines, including the 2007 and 2010 AHA/ACC guidelines and scientific statements for the prevention and management of infective endocarditis and for the management of cardiovascular device infections. The evidence-based guidelines, including the 2009 HRS consensus document, for the treatment of patients with cardiovascular device-related infections are also reviewed. Only patients with prosthetic valves, patients with prior endocarditis, cardiac transplant patients with a valvulopathy, and certain congenital heart disease patients now require endocarditis prophylaxis. There is an increasing incidence of cardiovascular device-related infections due to the higher frequency of implanted devices and higher morbidity and mortality rates in older patients.

    The occurrence of aorto-right ventricular (aorto-RV) fistula after prosthetic aortic valve replacement is rare. Transthoracic echocardiography (TTE) with color-flow Doppler, transesophageal echocardiography (TEE), or both may be required for diagnosis. A 42-year-old woman sought care for palpitations and dyspnea due to atrial flutter 2 weeks after prosthetic aortic valve replacement and graft replacement of the ascending aorta. TTE and TEE revealed left-to-right shunt due to aorto-RV fistula.

    Whilst it used to affect mostly intravenous drug users and patients who underwent valvular surgery with suboptimal infection control procedures, fungal endocarditis is now mostly observed in patients with severe immunodeficiency (onco-haematology), in association with chronic central venous access and broad-spectrum antibiotic use. The incidence of fungal endocarditis has probably decreased in most developed countries with access to harm-reduction policies (i.e. needle exchange programmes) and with improved infection control procedures during cardiac surgery. Use of specific blood culture bottles for diagnosis of fungal endocarditis has decreased due to optimisation of media and automated culture systems. Meanwhile, the advent of rapid techniques, including fungal antigen detection (galactomannan, mannan/anti-mannan antibodies and β-1,3-d-glucans) and PCR (e.g. universal fungal PCR targeting 18S rRNA genes), shall improve sensitivity and reduce diagnostics delays, although limited data are available on their use for the diagnosis of fungal endocarditis. New antifungal agents available since the early 2000s may represent dramatic improvement for fungal endocarditis: (i) a new class, the echinocandins, has the potential to improve the management of Candida endocarditis owing to its fungicidal effect on yeasts as well as tolerability of increased dosages; and (ii) improved survival in patients with invasive aspergillosis with voriconazole compared with amphotericin B, and this may apply to Aspergillus sp. endocarditis as well, although its prognosis remains dismal. These achievements may allow selected patients to be cured with prolonged medical treatment alone when surgery is considered too risky.

    Infective endocarditis has continuously evolved since its first clinical description by William Osler in the late 19th century. The epidemiological and microbiological profile of the disease has changed as the result of the progress of the medical care and demographic mutation in industrialized countries. Furthermore, advances in anti-infective therapy and in cardiovascular surgery have contributed to an improvement in the management and the prognosis of this severe infectious disease. During the past decade, the recommendations on antibiotic prophylaxis against infective endocarditis have changed dramatically. Guidelines on management of infective endocarditis and state-of-the-art articles have been published recently and this work aims to outline current recommendations about this evolving disease.

    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.

    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

    This study is aimed at analyzing clinical features, angiographic findings and evolution of Takayasu's arteritis and the criteria adopted to establish the indication for non-surgical versus operative treatment. Eighteen patients affected by non specific aortarteritis were observed and treated at our Department between 1973 and 1996. All patients met the American College of Rheumatology 1990 criteria of classification of Takayasu's arteritis. Sixteen patients were young females. Two patients were males. Nine patients underwent surgical procedures. One young female underwent a PTA. All eight asymptomatic patients were only medically treated. One patient died some days after an aorto-bicarotid bypass graft due to acute myocardial infarction. Two other patients died two and four years after intervention for renal and cardiac failure respectively. One patient after an aorto bicarotid bypass underwent a left hemiplegia due to thrombosis of the right graft branch. All the other 14 patients either surgically or medically treated are well and are under strict surveillance through rigorous follow-up. The 10 patients who underwent surgical or interventional radiological treatment were certainly the most seriously affected patients and were symptomatic (presented neurological disturbances or a severe hypertensive state). This fact explains, to some extent, the mortality and morbidity rate observed in this group. The seven medically treated patients were completely asymptomatic in spite of a major involvement of various vascular districts.

    Despite advances in diagnosis and treatment, infective endocarditis still shows considerable morbidity and mortality rates. The dermatological examination in patients with suspected infective endocarditis may prove very useful, as it might reveal suggestive abnormalities of this disease, such as Osler’s nodes and Janeway lesions. Osler’s nodes are painful, purple nodular lesions, usually found on the tips of fingers and toes. Janeway lesions, in turn, are painless erythematous macules that usually affect palms and soles. We report a case of infective endocarditis and highlight the importance of skin examination as a very important element in the presumptive diagnosis of infective endocarditis.

    Full Text Available With the development of penicillin, Streptococcus pneumoniae has become an uncommon cause of bacterial endocarditis in adults. Subacute manifestation of pneumococcal endocarditis has been reported a few times in the literature, but most reports define the disease as acute, severe, and having a high mortality rate. We report the case of a 58-year-old male with subacute bacterial endocarditis due to Streptococcus pneumoniae. We stress the low frequency of this agent as a cause of endocarditis and the atypical evolution of this case. The pathophysiology, clinical manifestations and evolution, and the therapeutical options for this type of infection are also discussed.

    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.

A pesar de los muchos avances en inmunología y el manejo de las complicaciones, la mortalidad y morbilidad asociadas a este trasplante son muy superiores a los demás. El rechazo agudo es casi un problema universal en el primer año, mientras que la bronquiolitis obliterante limita la supervivencia a largo plazo. Las infecciones respiratorias también cumplen un papel importante en las complicaciones asociadas al trasplante pulmonar por la constante exposición del injerto al medio exterior. No obstante, los éxitos de esta opción terapéutica que depende fundamentalmente de una correcta selección de donante y receptor, son evidentes, sobre todo en cuanto a calidad de vida se refiere.A lung transplant is usually the final therapeutic option for patients with respiratory insufficiency. In spite of the many advances in immunology and the management of complications, mortality and morbidity associated with this transplant are far higher than with others. Acute rejection is an almost universal problem in the first year, while obliterative bronchitis reduces long term survival. Respiratory infections also play a significant role in the complications associated with lung transplants due to the constant exposure of the graft to the outside. However, the success of this therapeutic option, which basically depends on a suitable selection of donor and recipient, are evident, above all with respect to quality of life.

  2. Extracardiac manifestations of bacterial endocarditis.

    1979-08-01

    Bacterial endocarditis is an elusive disease that challenges clinicians' diagnostic capabilities. Because it can present with various combinations of extravalvular signs and symptoms, the underlying primary disease can go unnoticed.A review of the various extracardiac manifestations of bacterial endocarditis suggests three main patterns by which the valvular infection can be obscured. (1) A major clinical event may be so dramatic that subtle evidence of endocarditis is overlooked. The rupture of a mycotic aneurysm may simulate a subarachnoid hemorrhage from a congenital aneurysm. (2) The symptoms of bacterial endocarditis may be constitutional complaints easily attributable to a routine, trivial illness. Symptoms of low-grade fever, myalgias, back pain and anorexia may mimic a viral syndrome. (3) Endocarditis poses a difficult diagnostic dilemma when it generates constellations of findings that are classic for other disorders. Complaints of arthritis and arthralgias accompanied by hematuria and antinuclear antibody may suggest systemic lupus erythematosus; a renal biopsy study showing diffuse proliferative glomerulonephritis may support this diagnosis. The combination of fever, petechiae, altered mental status, thrombocytopenia, azotemia and anemia may promote the diagnosis of thrombotic thrombocytopenic purpura. When the protean guises of bacterial endocarditis create these clinical difficulties, errors in diagnosis occur and appropriate therapy is delayed. Keen awareness of the varied disease presentations will improve success in managing endocarditis by fostering rapid diagnosis and prompt therapy.

    2009-01-01

    Full Text Available Introduction. Bacteria from genus Enterococcus may cause infections mostly in those who are immunocompromised and those who underwent endoscopic or surgical procedures. Endocarditis is caused by enterococci in 5-10% of cases. Its clinical presentation does not differ from endocarditis of other bacterial origin. Previous susceptibility testing is needed for appropriate choice of antibiotics against enterococci. The treatment recommendations for enterococcal endocarditis were given by American Heart Association recently. Case report. A case of enterococcal endocarditis in a young female person hospitalised at Clinic for infectious diseases was reviewed. The disease was diagnosed during an extensive diagnostic procedure. Multiply repeated echocardiographic examination helped to find out bacterial vegetations on the mitral valve. Enterococcus species was isolated from several blood cultures. Despite powerful antibiotic treatment, the additional valvular replacement had to be done. Discussion. A case of enerococcal endocarditis in a young female person was reviewed. The right diagnosis was based on a thorough clinical examination in cooperation with cardiologists using repeated transthoracic and transesophageal echocardiography. Echocardiography, even if it is transesophageal, has limited sensitivity and specify, so it is sometimes necessary to be repeated for several times in diagnosing endocarditis. The source of endocarditis was not identified. The combined antimicrobial and surgical treatment led to the complete recovery of patient. Conclusion. Enterococcal endocarditis rarely occurrs in young females. Infective disease specialists sometimes face enterococcal endocarditis in their practice, mostly when they have to cope with fever of unknown origin. An appropriate approach to such conditions includes careful search for heart valve changes by repeated echocardiographic finding, if necessary.

    Bacterial endocarditis (BE) is a disease resulting from the association of morphological alterations of the heart and bacteraemia originating from different sources that at times can be indiscernible (infectious endocarditis). It is classified on the basis of the morphological alteration involved, depending on the clinical manifestations and course of illness, which varies according to the causative microorganism and host conditions (for example, it is characteristic in I.V. drug users). The most common microorganisms involved are: Streptococcus viridans (55%), Staphylococcus aureus (30%), Enterococcus (6%) and HACEK bacteria (corresponding to the initials: Haemophilus, Actinobacillus, Cardiobacterium, Eikenella and Kingella), although on occasions it can also be caused by fungi. The oral microbiological flora plays a very important role in the aetiopathogenesis of BE, given that the condition may be of oral or dental origin. This paper will deal with the prevention of said bacteraemia. Prophylaxis will be undertaken using amoxicillin or clindamycin according to action protocols, with special emphasis placed on oral hygiene in patients with structural defects of the heart.

    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.

    Major advances in imaging and microbiological procedures have changed the diagnostic approach of infective endocarditis. New imaging tools have improved the search of local complications, systemic embolism and diagnosis of infection of cardiac devices. Moreover, microbiological diagnosis has been transformed by molecular techniques as long as these procedures have highlighted microorganisms thus far neglected by classical techniques. Despite these advances, endocarditis remained a clinical diagnosis which still depends on a high index of clinical suspicion.

    Candida infective endocarditis (IE) is uncommon but often fatal. Most epidemiologic data are derived from small case series or case reports. This study was conducted to explore the epidemiology, treatment patterns, and outcomes of patients with Candida IE. We compared 33 Candida IE cases to 2,716 patients with non-fungal IE in the International Collaboration on Endocarditis-Prospective Cohort Study (ICE-PCS). Patients were enrolled and the data collected from June 2000 until August 2005. We noted that patients with Candida IE were more likely to have prosthetic valves (p < 0.001), short-term indwelling catheters (p < 0.0001), and have healthcare-associated infections (p < 0.001). The reasons for surgery differed between the two groups: myocardial abscess (46.7% vs. 22.2%, p = 0.026) and persistent positive blood cultures (33.3% vs. 9.9%, p = 0.003) were more common among those with Candida IE. Mortality at discharge was higher in patients with Candida IE (30.3%) when compared to non-fungal cases (17%, p = 0.046). Among Candida patients, mortality was similar in patients who received combination surgical and antifungal therapy versus antifungal therapy alone (33.3% vs. 27.8%, p = 0.26). New antifungal drugs, particularly echinocandins, were used frequently. These multi-center data suggest distinct epidemiologic features of Candida IE when compared to non-fungal cases. Indications for surgical intervention are different and mortality is increased. Newer antifungal treatment options are increasingly used. Large, multi-center studies are needed to help better define Candida IE.

Recent studies in various countries and in Argentina have shown that the clinical profile of infective endocarditis has changed. Currently the patients are older with higher frequency of degenerative valve disease and prosthetic valve and nosocomial endocarditis. The incidence of Staphylococcus aureus as etiological agent has increased. These changes may justify the absence of decrease in mortality and suggests that more aggressive measures are needed based on prospective, well designed and controlled trials.

    Infective endocarditis (IE) is a difficult and complex disease. In recent years epidemiology and microbiology have changed. In developed countries IE is now affecting older patients and patients with no previously known valve disease. Prosthetic IE (prosthetic valve endocarditis [PVE]) and endocarditis in patients with pacemakers and other devices (cardiac device related infective endocarditis [CDRIE]) are becoming more frequent. The number of Staphylococcus aureus IE is increasing related to the number of endocarditis that occurs because of health care associated procedures, especially in diabetics or patients on chronic hemodialysis. The change in the underlying population and the increase in the number of cases caused by very virulent organism explain why the disease still carries a poor prognosis and a high mortality. The variety of clinical manifestations and complications, as well as the serious prognosis, makes it mandatory that IE patients need to be treated in experienced hospitals with a collaborative approach between different specialists, involving cardiologists, infectious disease specialists, microbiologists, surgeons, and frequently others, including neurologists and radiologists. Only an early diagnosis followed by risk stratification and a prompt institution of the correct antibiotic treatment as well as an appropriate and timed surgical indication may improve mortality figures. The recent European Guidelines try to provide clear and simple recommendations, obtained by expert consensus after thorough review of the available literature to all specialists involved in clinical decision-making of this difficult and changing disease.

    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 [sup 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.

    Abstract Tropheryma whipplei endocarditis is an uncommon condition with very few series and <90 cases reported in the literature. The aim of the study was to analyze the epidemiological, clinical, and outcome characteristics of 17 cases of T. whipplei endocarditis recruited in our country from a multicentric cohort from 25 Spanish hospitals from the Spanish Collaboration on Endocarditis—Grupo de Apoyo al Manejo de la Endocarditis infecciosa en España. From a total of 3165 cases included in the cohort, 14.2% were diagnosed of blood culture negative endocarditis (BCNE) and 3.5% of these had T. whipplei endocarditis. This condition was more frequent in men. The average age was 60.3 years. Previous cardiac condition was present in 35.3% of the cases. The main clinical manifestation was cardiac failure (76.5%) while fever was only present in the 35.3%. Ecocardiography showed vegetations in 64.7% of patients. Surgery was performed in all but 1 cases and it allowed the diagnosis when molecular assays were performed. A broad range rRNA 16S polymerase chain reaction was used for first instance in all laboratories and different specific targets for T. whipplei were employed for confirmation. A concomitant Whipple disease was diagnosed in 11.9% of patients. All patients received specific antimicrobial treatment for at least 1 year, with no relapse and complete recovery. T. whipplei endocarditis is an uncommon condition with an atypical presentation that must be considered in the diagnosis of BCNE. The prognosis is very good when an appropriate surgical management and antimicrobial-specific treatment is given. PMID:27368042

    Blood culture-negative endocarditis is often severe, and difficult to diagnose. The rate of non-documented infective endocarditis has decreased with the advent of molecular biology - improved performance for the diagnosis of bacterial endocarditis with blood cultures sterilized by previous antibacterial treatment - and cardiac surgery - access to the main infected focus, the endocardium, for half of the patients. Blood culture-negative endocarditis are classified in 3 main categories: (i) bacterial endocarditis with blood cultures sterilized by previous antibacterial treatment (usually due to usual endocarditis-causing bacteria, i.e. streptococci, more rarely staphylococci, or enterococci); (ii) endocarditis related to fastidious microorganisms (e.g. HACEK bacteria; defective streptococci - Gemella, Granulicatella, and Abiotrophia sp. - Propionibacterium acnes, Candida sp.): in these cases, prolonged incubation will allow identifying the causative pathogen in a few days; (iii) and the "true" blood culture-negative endocarditis, due to intra-cellular bacteria that cannot be routinely cultured in blood with currently available techniques: in France, these are most frequently Bartonella sp., Coxiella burnetti (both easily diagnosed by ad hoc serological tests), and Tropheryma whipplei (usually diagnosed by PCR on excised cardiac valve tissue). Non-infective endocarditis is rare, mostly limited to marantic endocarditis, and the rare endocarditis related to systemic diseases (lupus, Behçet).

    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.

    Infective endocarditis is a complex disease to treat. Despite considerable improvements in diagnostic and therapeutic management, mortality in infective endocarditis remains high. Recent data converge in giving a central role to surgery that, within a multidisciplinary approach and with earlier timing, primarily aims to eradicate the infection rather than to treat its acute or chronic complications. In this paper, we sought to review and comment on current available data and last recommendations for the management of patients with infective endocarditis.

    Full Text Available Transcatheter aortic valve replacement (TAVR techniques are rapidly evolving, and results of published trials suggest that TAVR is emerging as the standard of care in certain patient subsets and a viable alternative to surgery in others. As TAVR is a relatively new procedure and continues to gain its acceptance, rare procedural complications will continue to appear. Our case is about an 89-year-old male with extensive past medical history who presented with progressive exertional dyspnea and angina secondary to severe aortic stenosis. Patient got TAVR and his postoperative course was complicated by complete heart block, aorto-RV fistula, and ventricular septal defect (VSD formation as a complication of TAVR. To the best of our knowledge, this is the third reported case of aorto-RV fistula following TAVR as a procedural complication but the first one to show three complications all together in one patient.

    Endocarditis is a common disease in hospital practice. Identification of the microorganism responsible for the valvular damage is essential to establish the prognosis and to determine the optimal antibiotic treatment. In some cases of endocarditis the diagnosis is laborious, especially when the responsible microorganism is difficult to detect using standard culture techniques. Here we report a case of native aortic valve endocarditis due to Kingella kingae, a Gram negative organism of the HACEK group. In addition we review 6 other cases of endocarditis caused by organism belonging to this group, treated in our hospital between 1983 and 1999. Epidemiological studies show that less than 5% of all cases of endocarditis are caused by organisms of the HACEK group. The diagnosis is often delayed because their slow growth on a standard culture medium. We describe clinical and microbiological characteristics of this group of endocarditis.

    Cardiac hypertrophy is an early landmark during the clinical course of heart failure, and is an important risk factor for subsequent morbidity and mortality. The hypertrophy response to different types of cardiac overload is distinguished both at the molecular and cellular levels. These changes have been extensively characterized for pressure load hypertrophy; however, similar information for volume load hypertrophy is still needed. This study was undertaken to improve the existing method of producing experimental cardiac volume load. Previous investigators have employed surgical aorto-caval shunt (ACS) as a model for volume load hypertrophy (VO) in rats. The procedure is relatively simple and involves glue to seal the aortic hole after ACS. However, it has several limitations mostly related to the use of glue e.g. poor visualization due to hardening of tissues, imperfect sealing of the puncture site and glue seeping through the aortic hole resulting in shunt occlusion. We have modified the procedure using aortic adventitial suture instead of glue and 18G angiocatheter instead of 16G needle, which eliminated the technical difficulties from the former method. The ACS was visually confirmed at sacrifice, and the VO demonstrated by time-related changes in the heart weight/body weight ratio which increased from 78% at 4 weeks to 87% at 10 weeks and increased liver/body weight ratio by 22% at 10 weeks of post aorto-caval shunt. Cardiac expression of atrial natriuretic peptide (ANF) also demonstrated time-related increase in ANF mRNA (+275% increase at 4 weeks, p < 0.05, and +370% increase at 10 weeks, p < 0.001). This modified technique of aorto-caval shunt offers simpler, reproducible and consistent model for VO hypertrophy in rats.

    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.

    Mural endocarditis is a very rare condition. This entity involves bacterial growth on cardiac walls. In addition, concomitant valvular endocarditis, along with mural endocarditis, is an extremely rare combination. The diagnosis of mural endocarditis is difficult and requires more advanced cardiac imaging, such as a transesophageal echocardiogram. The differential diagnoses of mural masses include vegetations, thrombi, metastasis, and benign and malignant tumors. We present a rare and unusual case of Methicillin-Resistant Staphylococcus aureus bacteremia with findings of both right ventricular outflow tract mural endocarditis and valvular endocarditis involving the mitral valve.

    Aorto-caval fistula (ACF) is a rare complication of abdominal aortic aneurysm. It occurs in 1-6% of cases. The classic diagnostic signs of an ACF (pulsatile abdominal mass with bruit and right ventricular failure) are present only in a half of the patients. The most common diagnostic imaging procedures like ultrasound and computed tomography often are not sufficient enough. This leads to the delay in diagnosis, which has a great impact on the results of operation.

    Background 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. Methods 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 1992–2009. 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. Results 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. Conclusion 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. PMID:26683995

    Full Text Available Schwannoma é uma neoplasia mesenquimal, usualmente solitária, encontrada no mediastino, retroperitônio ou pelve, sendo rara sua apresentação na parede torácica. OBJETIVO: Relatar o caso de um paciente masculino, tabagista, com um nódulo pulmonar direito com características de malignidade, detectado em radiografia de tórax de rotina, cujo diagnóstico anatomopatológico foi de schwannoma benigno de nervo intercostal. MÉTODOS: Revisaram-se os dados referentes ao quadro clínico, exames laboratoriais e de imagem (radiografia e tomografia computadorizada de tórax do caso em estudo, assim como os exames anatomopatológico e imuno-histoquímico do espécime cirúrgico. RESULTADOS: O paciente foi submetido à toracotomia direita diagnóstica com ressecção da tumoração. O exame anatomopatológico convencional mostrou células tumorais de aspecto fusiforme, dispostas em paliçada, formando os corpos de Verocay, compatível com schwannoma intercostal. A imuno-histoquímica foi positiva para proteína S-100, vimentina e enolase, e negativa para neurofilamentos. CONCLUSÃO: O diagnóstico definitivo de schwannoma só é possível por meio da análise histopatológica e imuno-histoquímica da lesão. Seu aspecto celular, associado à atividade mitótica e a áreas de pleomorfismo, pode levar ao diagnóstico incorreto de malignidade. A imuno-histoquímica, por meio da proteína S-100, é útil na caracterização da benignidade da lesão, já que não é detectada nas lesões malignas. Os schwannomas de parede torácica podem simular neoplasias pulmonares na radiografia e tomografia computadorizada de tórax.

    1998-01-01

    Full Text Available Acute disseminated histoplasmosis is a frequent condition in HIV carriers. Thirty-five cases of endocarditis caused by Histoplasma capsulatum have been reported in international literature, and all these descriptions correspond to a context of subacute disseminated histoplasmosis. This paper presents the case of a HIV-positive patient with fever, dyspnea, weight loss, vomiting and polyadenopathies to whom histoplasmosis was diagnosed following blood-cultures and isolation of the agent responsible for cutaneous lesions, and in whom aortic-valve vegetations were found during an echocardiogram. The patient was treated with amphotericin B and had a good outcome; subsequent echocardiograms showed no vegetations. Literature on the subject is reviewed, with special emphasis on diagnosis and treatment of previously described cases.

    The HACEK group of bacteria - Haemophilus parainfluenzae, Aggregatibacter spp. (A. actinomycetemcomitans, A. aphrophilus, A. paraphrophilus, and A. segnis), Cardiobacterium spp. (C. hominis, C. valvarum), Eikenella corrodens, and Kingella spp. (K. kingae, K. denitrificans) - are fastidious gram-negative bacteria, part of the normal microbiota of oral and upper respiratory tract in humans. Although their pathogenicity is limited, they are responsible for 1-3% of all infective endocarditis. HACEK endocarditis mostly affect patients with underlying heart disease or prosthetic valves, and are characterized by an insidious course, with a mean diagnosis delay of 1 month (Haemophilus spp.) to 3 months (Aggregatibacter and Cardiobacterium spp.). The advent of continuously monitored blood culture systems with enriched media has erased the need for extended incubation for the diagnosis of HACEK endocarditis. Medical treatment relies on third-generation cephalosporin, with a favorable outcome in 80-90% of cases, with or without cardiac surgery.

  5. Valve selection in aortic valve endocarditis

    Science.gov (United States)

    Zubrytska, Yana

    2016-01-01

    Aortic prosthetic valve endocarditis (PVE) is a potentially life-threatening disease. Mortality and incidence of infective endocarditis have been reduced in the past 30 years. Medical treatment of aortic PVE may be successful in patients who have a prompt response after antibiotic treatment and who do not have prosthetic dysfunction. In advanced stages, antibiotic therapy alone is insufficient to control the disease, and surgical intervention is necessary. Surgical treatment may be lifesaving, but it is still associated with considerable morbidity and mortality. The aim of surgery is to perform a radical excision of all infected and necrotic tissue, reconstruction of the left ventricle outflow tract, and replacement of the aortic valve. There is no unanimous consensus on which is the optimal prosthesis to implant in this context, and several surgical techniques have been suggested. We aim to analyze the efficacy of the surgical treatment and discuss the issue of valve selection in patients with aortic valve endocarditis.

    2012-02-01

    Full Text Available Endogenous endophthalmitis is a rare ocular infection affecting the vitreous and/or aqueous humours. It is associated with poor visual prognosis and its commonest endogenous aetiology is infective endocarditis. The causative organisms of endogenous endophthalmitis complicating endocarditis are mainly Group A or B streptococci. The identification of Group C and G streptococci such as Streptococcus dysgalactiae is comparatively uncommon and has only been reported in a few case reports or series. We therefore report a case of infective endocarditis caused by Streptococcus dysgalactiae first presenting with endogenous endophthalmitis, the most likely source being bilateral feet osteomyelitis in a patient with type I diabetes. The patient was treated with a course of intravenous benzylpenicillin, intravitreal antibiotics, bilateral below knee amputations and mitral valve replacement. She survived all surgical procedures and regained partial visual acuity in the affected eye.

    The endocarditis stays a dangerous illness. The positive microbiological diagnosis has a precious contribution for a successful hold in charge of the patient. To optimise the microbiological diagnosis of the endocarditis, essentially it comes back to respect the maximum rules of good practice of the blood cultures and the microbiological cardiac valve exams. During the last decades, techniques of molecular biology came to remedy insufficiencies of the conventional microbiology. We arrange rich microbiological data to guide the therapist while waiting the current microbiological data of the patient.

    Transcatheter aortic valve replacement (TAVR) can improve the symptoms and prognosis of patients with severe aortic stenosis who, due to a high expected operative risk, would not have otherwise been treated surgically. If these patients develop prosthetic valve endocarditis, their presentations may...... be atypical causing a delay in the diagnosis and treatment. The management is also complicated by their comorbidities, and surgical treatment may not be feasible leading to a significant morbidity and mortality. We describe a case of an 85-year-old man with TAVI prosthetic valve endocarditis successfully...

  9. Emergency Department Management Of Acute Infective Endocarditis.

    Schauer, Steven G; Pfaff, James A; Cuenca, Peter John

    2014-11-01

    Infective endocarditis has a high rate of mortality, and most patients suspected of having the disease will require hospital admission. This review examines the literature as it pertains specifically to emergency clinicians who must maintain vigilance for risk factors and obtain a thorough history, including use of intravenous drugs, in order to guide the workup and treatment. Properly obtained cultures are critical during the evaluation, as they direct the course of antibiotic therapy. Although transthoracic echocardiography is widely available in United States emergency departments, it is not sensitive or specific enough to rule out a diagnosis of infective endocarditis. In high-risk patients, transesophageal echocardiography should be considered.

    Primary aorto-enteric fistula (PAEFis a serious complication of abdominal aortic aneurysm(AAA. We report a patient with PAEF associated with inflammatory AAA who underwent emergent surgery. A 52-year-old male presented with recurrent hematemesis. A computer tomography scan showed a sealed rupture of the AAA adjacent to the duodenum. At surgery, a coin-sized PAEF was noted. The aorta was replaced with a Dacron graft in situ . Histological examination revealed the characteristics of an inflammatory AAA. The postoperative course was uneventful, and there has been no evidence of infection during a follow-up period of 3 years. We discuss the etiologic and surgical considerations regarding this unusual entity.

    2005-09-01

    Full Text Available Abstract Background Right-sided endocarditis occurs predominantly in intravenous drug users, in patients with pacemaker or central venous lines and in patients with congenital heart disease. The vast majority of cases involve the tricuspid valve. Eustachian valve endocarditis is an uncommon disease with similar signs and symptoms of the tricuspid valve endocarditis. A series of only 16 cases of eustachian valve endocarditis are reported in the literature. Case Presentation We present a case of a 25-year old woman with intravenous drug abuse who had a staphylococcus aureus tricuspid valve endocarditis associated to eustachian valve endocarditis. Transthoracic echocardiography, as first line examination, showed the vegetations on tricuspid and eustachian valve. Conclusion Our case describe an unusual location of right side endocarditis in a intravenous drug abuser. In our case, in accord with other cases described in the literature, transthoracic echocardiography disclosed eustachian valve endocarditis. Antimicrobial management is not altered by the recognition of eustachian valve endocarditis. Antibiotic treatment and duration of eustachian endocarditis depends on the isolated organism and is similar to antibiotic therapy used in native valve endocarditis.

    We present a 54-year-old woman with systemic lupus erythematosus (SLE), fever, pericardial effusion and a mitral valve vegetation. (18)F-Fluorodesoxyglucose positron emission tomography CT ((18)F-FDG-PET-CT) showed very high accumulation of the isotope at the mitral valve. The patient underwent cardiothoracic surgery and pathologic examinations showed characteristic morphology of Libman-Sacks vegetations. All microbiological examinations including blood cultures, microscopy, culture and 16s PCR of the valve were negative and the diagnosis of Libman-Sacks endocarditis was convincing. It is difficult to distinguish Libman-Sacks endocarditis from culture-negative infective endocarditis (IE). Molecular imaging techniques are being used increasingly in cases of suspected IE but no studies have previously reported the use in patients with Libman-Sacks endocarditis. In the present case, (18)F-FDG-PET-CT clearly demonstrated the increased glucose uptake caused by infiltrating white blood cells in the ongoing inflammatory process at the mitral valve. In conclusion, (18)F-FDG-PET-CT cannot be used to distinguish between IE and non-infective Libman-Sacks vegetations.

    2014-12-01

    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

    2011-01-01

    Full Text Available Endocarditis due to Achromobacter species is a rare, yet serious, endovascular infection. Achromobacter species infective endocarditis is associated with underlying immunodeficiencies or prosthetic heart valves and devices. A case of prosthetic pulmonary valve endocarditis secondary to Achromobacter xylosoxidans subspecies denitrificans is described in the present report. This life-threatening infection was successfully treated with combined valve replacement and prolonged antibiotic therapy. A Medline/PubMed literature review of Achromobacter endocarditis was also performed. Achromobacter species are an uncommon, yet important, cause of nosocomial endocarditis. Given the significant associated morbidity and mortality, along with a high degree of intrinsic antibiotic resistance, Achromobacter species infective endocarditis remains a clinical treatment challenge.

    Full Text Available En 1983 se reportaron 20 enfermos con un tumor pulmonar raro que fue entonces llamado IVBAT, por sus siglas en inglés (tumor intravascular bronquio-alveolar. Los pacientes se presentaron con numerosos nódulos pulmonares, de crecimiento lento, cuyos hallazgos histológicos variaban desde una apariencia benigna granulomatosa hasta una claramente maligna sarcomatosa. Eventualmente se demostró que el tumor era de origen vascular y se le llamó hemangioendotelioma epiteliode (HEE. Poco después se describió en otras regiones anatómicas. Reportamos aquí el primer caso costarricense de esta estirpe histológica y de presentación pulmonar. Un hombre de 42 años de edad, nos fue referido en fase final con metástasis generalizadas, aunque en buenas condiciones generales. Se le practicó una biopsia pulmonar para definir la histología, pero falleció poco tiempo después sin responder a la terapia instituida. Dieciséis años antes se le habían descubierto nódulos pulmonares pequeños bilaterales y mediante una biopsia abierta se le hizo el diagnostico de HEE. Como el curso de su enfermedad fue considerado estable durante ese tiempo había sido seguido clínicamente. Se comparó el material de la biopsia inicial con el de la reciente, encontrándose mucho mayor celularidad y atipia en la última. Se efectuaron análisis inmunohistoquímicos con un panel de anticuerpos, que permitió establecer la naturaleza vascular del tumor. El HEE es un tumor muy raro, de crecimiento lento y de bajo potencial metastásico, a pesar de ser de origen vascular. Llama la atención el fenómeno de dependencia hormonal de este tumor, que se plantea en la literatura, y que sugiere otras avenidas terapéuticas.

Pairing a detailed history with the consideration of atypical agents is crucial in the proper diagnosis and management of endocarditis in patients with high-risk injection behaviors.

    A well known complication in the treatment of infectious endocarditis is development of neutropenia caused by treatment with antibiotics in high concentrations over long periods. Neutropenia often necessitates discontinuation of antibiotic treatment. Three patients with infectious endocarditis who developed neutropenia are reported. The patients were treated with granulocyte colony stimulating factor (G-CSF), a haematopoietic growth factor that stimulates neutrophils. G-CSF induced an immediate increase in white blood cell count, primarily neutrophils. G-CSF may be effective in ameliorating neutropenia in patients who receive antibiotics for treatment of infectious endocarditis.

    Valve endocarditis is associated with high morbidity and mortality and requires a thorough evaluation including early surgical consultation to identify patients who may benefit from surgery. We review 5 recent articles that highlight the current debates related to best treatment strategies for valve endocarditis. Recent publications have focused on neurologic risk assessment, timing of surgery, and prognostic factors associated with native and prosthetic valve endocarditis. The initial patient assessment and management is best performed by a multidisciplinary team. Future investigations should focus on identifying surgical candidates early and the outcomes affected by replacement valve choice in both native and prosthetic valve endocarditis.

    Infective endocarditis is relatively uncommon in the pediatric population, but when it does occur, results in substantial morbidity and mortality. Children at risk for endocarditis are typically those with an underlying congenital heart condition. Furthermore, an endocardial abscess is a very rare yet serious complication of infective endocarditis. We describe a case of a 23-month-old previously healthy male infant with no known congenital heart disease who returned to the emergency department after a recent hospitalization for pneumococcal bacteremia, presenting acutely ill but without fever. He was found to be in congestive heart failure due to endocarditis and an aortic root abscess.

    A 70-year-old patient with a history of hypertension and hypercholesterolemia was referred for evaluation of necrotic toes. The patient had a history of several cerebrovascular accidents during the previous month. Initially, she developed sudden-onset left upper extremity weakness which, over the ensuing 4 days, progressed to complete left-sided weakness. This was followed by the development of acute dysarthria. A transesophageal echocardiogram revealed moderate left ventricular hypertrophy, several vegetations on her tri-leaflet aortic valve associated with moderate aortic regurgitation, and a large right atrial thrombus with a mobile component. Bubble studies failed to reveal any septal defects. The patient's electrocardiogram was nonspecific. As serial blood cultures were negative despite fevers of up to 39.8 degrees C, the patient was treated with a 6-week course of intravenous ceftriaxone, ampicillin, gentamicin, and ciprofloxacin for a presumed diagnosis of culture-negative endocarditis. Fungal cultures of the blood were negative. The patient, however, progressed and developed several necrotic toes. Physical examination was significant for ischemic changes of the left first, second, third, and fifth toes, as well as the right first and second toes. Diffuse subungual splinter hemorrhages in the toenails, numerous 2-4-mm palpable purpuric papules on the lower extremities, and nontender hemorrhagic lesions of the soles were also noted. Peripheral and carotid pulses were intact and no carotid bruits were heard. Cardiopulmonary and abdominal examinations were unremarkable. Neurologic examination revealed a disoriented, dysarthric patient with left central facial nerve paralysis, as well as spasticity, hyperactive reflexes, and diminished strength and sensation in the left upper and lower extremities. A left visual field defect and left hemineglect were also present. The patient's last brain computerized tomogram revealed areas of low attenuation consistent with

    A 23 year old female presented with dyspnea on exertion and absent pulses in the left upper limb. She had prior history of two first trimester abortions and pre-eclampsia with premature delivery. A Doppler examination had revealed left subclavian and axillary artery thrombosis for which she had been given warfarin six months previously. She was admitted and investigated. Patient had low positive aCL IgG antibody, positive antibeta2gp1 antibody, negative lupus anticoagulant and negative ANA. Patient had cardiomegaly and her echocardiography showed severe aortic regurgitation, moderate mitral regurgitation and moderate pulmonary artery hypertension with poor ejection fraction with normal aortic root. A diagnosis of primary antiphospholipid antibody syndrome with valvular involvement with dilated cardiomyopathy was entertained. A CT angiogram of the aorta revealed narrowing and irregularity of the aorta and its multiple branches suggestive of type III Takayasu's arteritis. Temporal relationship suggests development of aorto-arteritis secondary to APS but simultaneous presence of both these disorders in this patient cannot be ruled out.

    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.

    2009-04-01

    Full Text Available Marantic endocarditis, otherwise known as nonbacterial thrombotic endocarditis (NBTE, is a well-documented phenomenon due to hypercoagulability from an underlying cause. It has been associated with a variety of inflammatory states including malignancy. Surprisingly, although hypercoagulability is often seen in patients with pancreatic cancer, marantic endocarditis has rarely been reported antemortem in this population. We report three cases of marantic endocarditis in patients with advanced pancreatic cancer. In two instances, the patients’ neurological symptoms preceded the diagnosis of advanced pancreatic cancer. Health care professionals should be alert to the possibility of marantic endocarditis in any patient with cancer, especially pancreatic cancer, who presents with symptoms of neurological dysfunction or an arterial thrombotic event. Prompt diagnosis and treatment with heparin, unfractionated or low molecular weight, may prevent catastrophic CNS events and decrease morbidity in patients with pancreatic cancer and other malignancies.

    Full Text Available Abstract Introduction Bartonella spp. infection is not rare and must be considered with great care in patients with suspected infective endocarditis, particularly if regular blood cultures remain sterile. Management of these infections requires knowledge of the identification and treatment of these bacteria. Case presentation A 50-year-old Senegalese man was admitted to our Department of Cardiac Surgery with a culture-negative endocarditis. Despite valvular surgery and adequate antibiotic treatment, recurrence of the endocarditis was observed on the prosthetic mitral valve. Heart failure required circulatory support. Weaning off the circulatory support could not be attempted owing to the absence of heart recovery. Bacteriological diagnosis of Bartonella quintana endocarditis was performed by molecular methods retrospectively after the death of the patient. Conclusions This case report underlines the severity and difficulty of the diagnosis of Bartonella quintana endocarditis. The clinical picture suggested possible Bartonella quintana associated myocarditis, a feature that should be considered in new cases.

A dissecção prosseguiu com rotação medial do cólon esquerdo. O avental, posteriormente fixo à linha mediana, serviu de anteparo às alças intestinais. Pinçamos a aorta e realizamos enxerto aorto-femoral com o tempo abdominal totalmente laparoscópico. RESULTADO: O enxerto foi realizado com sucesso, e o fluxo sangüíneo na prótese foi demonstrado através da incisão femoral. CONCLUSÃO: O enxerto aorto-femoral experimental laparoscópico é exeqüível através da exposição com a técnica do avental.OBJECTIVE: To verify the feasibility of the aortofemoral laparoscopic bypass. METHOD: We operated on a 75-kg pig under general anesthesia. The aorta was exposed using Dion's "apron" technique. Briefly, the animal was placed in supine position and the parietal peritoneum was dissected away from the left of the midline. The dissection proceeded with medial rotation of the left colon. This constructed apron (parietal peritoneum, left colon and mesocolon, in continuity was sutured to the midline. It served to keep the sliding bowel away from the operative field. After clamping the aorta, we performed an aortofemoral bypass with a totally laparoscopic abdominal time. RESULT: The bypass was successfully performed, and the blood flow through the prosthesis was considered adequate when verified at the femoral incision. CONCLUSION: The experimental laparoscopic aortofemoral bypass is feasible using the apron exposure technique.

    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.

    2012-03-29

    Endovascular repair (EVAR) is accepted as effective treatment for abdominal aortic aneurysms (AAAs) and has become the standard of care in many instances. The standard bifurcated stentgraft (BFG) is often not possible in patients with unfavourable aneurysm morphology. The aorto-uni-iliac (AUI) graft configuration with femoro-femoral bypass (FFBP) is a promising alternative which may extend the scope of EVAR for AAAs. The aim of this study was to evaluate the feasibility, efficacy and durability of AUI with FFBP. Design. The results of a single institution and a single surgeon were prospectively collected from January 2002 to August 2010. All patients were followed up at 1, 3, 6 and 12 months and then annually. Results. There were 33 patients (27 males) with a mean age of 71.7 years (range 46 - 84). Open surgery posed an unacceptably high risk to all patients owing to advanced age and/or American Society of Anesthesiologists (ASA) classification 3/4. Ineligibility for BFG was due to unfavourable anatomy or a combination of factors in most cases (31 patients). Two patients had anastomotic aneurysms after previous open surgery. The technical success rate was 100%. One severe intra-operative complication occurred (perforated iliac artery). Two patients (ASA 4) died within 30 days (peri-operative mortality rate 6.1%). Seven patients (21.1%) developed postoperative wound complications. Eight patients died during follow-up of non-aneurysm-related conditions. Twenty-three patients are alive, with mean follow-up of 24.4 months and a survival rate of 69.7%. Two complications occurred during long-term follow-up, namely 1 case of graft sepsis and 1 of FFBP occlusion. Conclusion. AUI with FFBP is a safe, effective and durable alternative in high-risk patients with AAAs where standard open repair is contraindicated and BFG repair is not possible owing to unfavourable aneurysm morphology.

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.

    Full Text Available O comprometimento valvar direto do coração pela endocardite infecciosa, com indicação cirúrgica, tem sido classicamente tratada por excisão da valva e tecidos adjacentes comprometidos, associada ou não a implante de prótese. Dois casos de operação conservadora em endocardite infecciosa da valva tricúspide com 42 e 3 meses de evolução são descritos. Os autores discutem as vantagens de, quando possível, não retirar toda a valva tricúspide na endocardite bacteriana.Valve replacement and excision without using a prosthesis are the two mostfrequently used surgical techniques for the treatment of infective endocarditis of the tricuspid valve. Conservative operation with preservation of the native valve and resection of the infected tissue is a more recent approach, which is becoming the procedure of choice whenever feasible, specialy in intravenous drug abusers. Two cases of tricuspid valve reconstruction with good results are reported. One of the patients has also been aorto coronary bypassed at the same operation time.

    Full Text Available Background: Infective endocarditis continues to challenge modern medicine despite its rare occurrence in the general population. Its incidence depends on risk groups. Correlation of anatomical and pathological findings with clinical and epidemiological elements may explain the current features of this condition. Objective: to describe the anatomical features of patients with infective endocarditis diagnosed at autopsy. Methods: A descriptive study including cases of infective endocarditis diagnosed at autopsy between 1986 and 2008 was conducted in the Provincial Clinical-Surgical Hospital Celia Sanchez, Granma. The variables analyzed were: age, sex, previous anatomical lesions, location of vegetations, multi-organ embolic infarcts and embolic abscesses, complications, culture of lesions and direct causes of death. Results: frequency of infective endocarditis diagnosed at necropsy ranged annually from 0.4 to 1.5%. Native valve endocarditis without previous damage was the most frequent. The anatomical findings were more common in the left side of the heart. Right-sided nosocomial endocarditis accounted for almost a third of the deceased patients and risk factors were identified. Embolic lesions affecting various organs, systemic complications and direct causes of death showed acute infectious endocarditis. The most common pathogen was Staphylococcus aureus. Conclusion: knowing the anatomical findings may contribute to the understanding of the clinical and epidemiological aspects of this condition. Correlation between anatomical and clinical findings was low; therefore difficulties in establishing the diagnosis during life are inferred.

    Brucella endocarditis is a rare but a severe complication of brucellosis, observed in less than 2% of cases. It is the main cause responsible for up to 80% of deaths in brucellosis. Herein, we present a case of brucella endocarditis that developed on a native aortic valve, but presented to us with fever for several months and acute neurological symptoms. This case report signifies the importance of considering brucella endocarditis as one of the differentials in patients presenting with Pyrexia of Unknown Origin (PUO) and Central Nervous System (CNS) manifestations.

    A 40-year old Indigenous woman with a history of mitral valve replacement was admitted to the Royal Darwin Hospital, Northern Territory, for an elective cone biopsy of the cervix. During the admission, she had recurrent fever and joint pain of the left knee. Blood was cultured, and she was treated with broad-spectrum antibiotics. Abiotrophia defectiva was identified from the culture, and a transoesophageal echocardiogram revealed endocarditis of the mitral valve prosthesis. A review of the English-language literature suggests that this is the first reported case of Abiotrophia endocarditis in Australia, and the third reported case of prosthetic-valve endocarditis caused by this species worldwide.

    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.

    The epidemiology of infective endocarditis is changing rapidly due to the emergence of resistant microorganisms, the indiscriminate use of antibiotics, and an increase in the implantation of cardiovascular devices including percutaneous valves. Percutaneous pulmonary valve implantation has achieved standard of care for the management of certain patients with right ventricular outflow tract dysfunction. With its expanding use, several cases of early and delayed infective endocarditis with higher morbidity and mortality rates have been reported. This review summarizes the trends in percutaneous pulmonary valve infective endocarditis, postulates proposed mechanisms, and elaborates on the prevention and management of this unique and potentially fatal complication.

    In a retrospective study of cases of infective endocarditis (IE) observed in adult patients, the data of patients hospitalized for definite IE in the Cardiosurgery Unit of ARNAS-Civico in Palermo (Italy) from March 2003 to September 2006 were analysed. All cases were classified according to the modified Duke criteria. In all, 36 immunocompetent patients with "definite" IE were included (20 males and 16 females with a median age of 54 years). The aortic valve (23/36, 64%) was the most commonly involved, followed by the mitral (19/36, 52.7%) and tricuspid valve (4/36, 11%). In 10 patients (27.7%), a double localization was observed. Blood culture yielded a positive result in 15 cases. Staphylococci and enterococci were the pathogens most commonly identified. Valvular diseases and previous cardiosurgical procedures were the risk factors most commonly noted. Four patients developed complications during the course of the disease, one of whom died. In patients with positive blood culture, antibiotics were prescribed on the basis of susceptibility test results. In patients with negative blood culture, empiric therapy was directed against Gram+ bacteria (glycopeptides, aminoglycosides and betalactams). Surgical therapy was necessary in 25 patients (69.4%). The patients were subsequently enrolled in a cardiological and infectivological follow-up. Our results showed that rapid diagnosis, correct antibiotic therapy and early surgical treatment improve the outcome in patients with infective endocarditis.

    Full Text Available Abstract Introduction Lactococcus garvieae is a well-recognized fish pathogen, and it is considered a rare pathogen with low virulence in human infection. We describe the 11th case of L. garvieae infective endocarditis reported in the literature, and the first reported case in Japan. Case presentation We report a case of a 55-year-old Japanese woman who had native valve endocarditis with L. garvieae. The case was complicated by renal infarction, cerebral infarction, and mycotic aneurysms. After anti-microbial treatment, she was discharged from the hospital and is now well while being monitored in the out-patient clinic. Conclusion We encountered a case of L. garvieae endocarditis that occurred in a native valve of a healthy woman. The 16S ribosomal RNA gene sequencing was useful for the identification of this pathogen. Although infective endocarditis with L. garvieae is uncommon, it is possible to treat high virulence clinically.

    A 46-year-old woman with sudden on set strong right flank pain was transferred to our hospital with the diagnosis of right renal infarction. Cardiac ultrasonography revealed a vegetation on the posterior cusp of the mitral valve, and the renal infarction was thought to be caused by renal artery embolism from infective endocarditis. Since the vegetation remained after antimicrobial therapy as conservative management, the patient was surgically treated by mitral annuloplasty. It has been known that infective endocarditis can cause renal infarction. Infective endocarditis requires immediate and adequate treatment because of high mortality. Therefore, the appropriate diagnosis of infective endocarditis is needed for patients with renal infarction without any other disorder causing renal infarction.

    Adults with chronic immunosuppressive conditions are at an increased risk for Streptococcus agalactiae endocarditis, which is typically characterized by acute onset, presence of large vegetations, rapid valvular destruction and frequent complications. We report a rare case of a 74 years old man presenting with fever, renal infarction, ischemic stroke and uveitis. Infective endocarditis was diagnosed and Streptococcus agalactiae was isolated in blood cultures. A multiple myeloma Ig G-K was also diagnosed. The infective endocarditis was successfully treated with a course of benzylpenicillin and gentamicin. The authors highlight the severity of vascular embolic disease present in this case and the diagnostic challenge. They also intend to remind about the association between Streptococcus agalactiae endocarditis and chronic diseases, despite its low reported prevalence.

  2. Sinus of Valsalva Pseudoaneurysm as a Sequela to Infective Endocarditis

    Siegel, Robert J.

    2016-01-01

    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.

    Full Text Available Organisms of the genus Gemella can, on occasion, cause serious systemic illness. The present paper reports a successfully treated case of endocarditis in a 12-year-old girl with congenital heart disease caused by species of Gemella. The child presented with cough, fatigue and decreased appetite without fever. Echocardiogram demonstrated marked mitral insufficiency with flail posterior mitral valve leaflet, mitral valve vegetations, and an enlarged left atrium and ventricle. While being treated with vancomycin, the child initially had persistent bacteremia, which resolved after the addition of gentamycin; the course of therapy was completed with penicillin G and gentamycin once antimicrobial susceptibilities were available. Attempts to identify the species of Gemella were unsuccessful in the local laboratory, and at reference laboratories in Canada and the United States. The isolate is undergoing further evaluation to determine its taxonomic status.

Produce altas tasas de morbilidad y mortalidad en todo el mundo, con una evolución lenta aunque progresivamente mortal, a pesar de tratarse de una enfermedad prevenible, que depende en gran medida, del hábito de fumar. La prevalencia variará según el consumo de tabaco, y se espera que siga aumentando en los próximos 25 años. La mortalidad y morbilidad son cada vez mayores, lo que supone un enorme gasto sanitario, social y personal, pero es una enfermedad potencialmente modificable, motivo por el que requiere de un abordaje multifactorial.Chronic Obstructive Pulmonary Disease has become one of the most frequently treated chronic diseases in primary health care. High rates of morbidity and mortality are worldwide related to this disease. Although it is a preventable disease closely related to smoking, its evolution is slow but progressively fatal. Prevalence varies according to tobacco consumption and is expected to increase in the next 25 years. Even when it is a potentially modifiable disease, mortality and morbidity are also increasing, causing a major health, social and personal spending. For all these reasons, a multifactorial approach is needed both, for health and social issues.

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.

    The incidence of tuberculosis has lately increased in developed countries. The most frequent affectation is the pulmonar one and in the ORL area the laryngeal. The lingual affectation is exceptional. We present a case of a man 39 years old, with bilateral pulmonar, left vocal cord and mobile tongue affectation, negative Mantoux, positive spit culture and presence of acido-alcohol resistent bacillus in lingual and laryngeal biopsies. After antituberculosis treatment during 6 months the laryngeal and lingual lesions disappeared.

    Full Text Available Introduction: Although a few patients will survive after penetrating cardiac injuries, some of them may have unnoticeable intracardiac injuries. The combination of aorto-right ventricular fistula with aortic valve injury is rare.Case Presentation: A 19 year-old man referred with an aorto-right ventricular fistula accompanied with aortic regurgitation and delayed tamponade following a stab in the chest. The patient was scheduled for fistula repair, aortic valve replacement and pericardectomy two months after trauma.Conclusions: To prevent missing intracardiac injury and also late cardiac injury complications, in all pericordial stab wounds, serial clinical examinations and serial echocardiography should be performed. In addition, cardiac injuries should be repaired during the same hospital stay.

  10. Isolated pulmonic valve endocarditis presenting as neck pain

    Directory of Open Access Journals (Sweden)

    Aditya Goud

    2015-12-01

    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.

    Full Text Available Sr. Editor: La tuberculosis es una de las enfermedades remergentes en Cuba; por ello en todas las provincias cubanas se trabaja con mucha fuerza, dedicación y profesionalidad con respecto a esta problemática. 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. Hubo fallas en el diagnóstico, ya que alrededor de la mitad de los casos se diagnosticaron en la atención secundaria y con un tiempo de demora de más de dos meses de

    2014-01-01

    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.

    2013-01-01

    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.

    2015-08-01

    Infective endocarditis is increasingly perceived as a byproduct of aggressive medications and/or invasive medical procedures. Some of the organisms are fungi, and in this situation, Candida species account for nearly half of all fungal IE. We report a single-institute pathological experience of 14 cases of candidial endocarditis among surgically excised cardiac tissues and autopsied cases in a 14-year period. Twelve of the 14 cases were seen as healthcare-associated invasive infections, and only five had been diagnosed antemortem. Candidial endocarditis was predominantly right-sided and valvular. The risk factors included underlying heart diseases, central venous catheterization and prolonged antibiotic therapy. Mortality among the autopsied patients was related to septicemia and/or embolic complications.

    This study reports six consecutive patients who underwent heart transplantation as salvage treatment for endocarditis (Duke criteria) with extensive perivalvular lesions and end-stage heart failure. The median age was 45 years (range, 24 to 64), and the aortic valve was affected in all patients. Pathogens were Staphylococcus aureus (n = 2), Streptococcus pneumoniae (n = 2), Streptococcus agalactiae (n = 1), or not documented (n = 1). All patients survived, with no relapse, after a median follow-up of 24.5 months. The 10 patients with heart transplantation for endocarditis previously reported also survived (median follow-up, 27.5 months). Heart transplantation may be considered as salvage treatment in selected patients with intractable infective endocarditis.

    Scedosporium prolificans, a hyaline filamentous fungus, is widely distributed in the environment and is currently an emerging human pathogen, especially among immunocompromised patients. However, S. prolificans endocarditis is rare. We herein report a case of S. prolificans endocarditis in a 64-year-old patient with breast cancer in complete remission for 30 years after chemotherapy and radiation treatment who was not cured. Susceptibility testing showed resistance to all antifungal drugs, except echinocandin. A review of the literature revealed 10 cases of S. prolificans endocarditis; of these, only one involved an immunocompetent host with no risk factors and only two patients survived. In order to improve the mortality rate, it is necessary to establish rapid diagnostic methods and efficient therapeutic approaches.

    Full Text Available Abstract Background Corynebacterium species are recognized as uncommon agents of endocarditis, but little is known regarding species-specific risk factors and outcomes in Corynebacterium endocarditis. Methods Case report and Medline search of English language journals for cases of Corynebacterium endocarditis. Inclusion criteria required that cases be identified as endocarditis, having persistent Corynebacterium bacteremia, murmurs described by the authors as identifying the affected valve, or vegetations found by echocardiography or in surgical or autopsy specimens. Cases also required patient-specific information on risk factors and outcomes (age, gender, prior prosthetic valve, other prior nosocomial risk factors (infected valve, involvement of native versus prosthetic valve, need for valve replacement, and death to be included in the analysis. Publications of Corynebacterium endocarditis which reported aggregate data were excluded. Univariate analysis was conducted with chi-square and t-tests, as appropriate, with p = 0.05 considered significant. Results 129 cases of Corynebacterium endocarditis involving nine species met inclusion criteria.

    Introduction: Citrobacter koseri is a gram-negative bacillus that rarely causes infection in immunocompetent hosts and typically is associated with urinary or respiratory tract infections. Rarely will Citrobacter be a cause of infective endocarditis. Case Report: We present a case of a 77-year-old man with no known immunocompromising conditions who was hospitalized for infective aortic endocarditis due to Citrobacter koseri originating from a chronically infected prostate. Unusually, he also developed a C. koseri diskitis and phlegmon, which, along with the aortic vegetations, increased in size despite appropriate antibiotics. The patient thus met indications for aortic valve replacement and had improved appearance of lesions in follow-up imaging.

    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.

    A 65-year-old Japanese man was admitted with a 4-month history of fatigue and exertional dyspnea. Transthoracic echocardiography revealed a vegetation on the aortic valve and severe aortic regurgitation. Accordingly, infective endocarditis and heart failure were diagnosed. Although a blood culture was negative on day 7 after admission, a prolonged blood culture with subculture was performed according to the patient's history of contact with cats. Consequently, Bartonella henselae was isolated. Bartonella species are fastidious bacteria that cause blood culture-negative infective endocarditis. This case demonstrates that B. henselae may be detected by prolonged incubation of blood cultures. PMID:27746451

    P. micra is an anaerobic Gram-positive cocci, and a known commensal organism of the human oral cavity and gastrointestinal tract. Although it has been classically described in association with endodontic disease and peritonsillar infection, recent reports have highlighted the role of P. micra as the primary pathogen in the setting of invasive infections. In its most recent taxonomic classification, P. micra has never been reported causing infectious endocarditis in humans. Here, we describe a 71 year-old man who developed severe native valve endocarditis complicated by aortic valvular destruction and perivalvular abscess, requiring emergent surgical intervention. Molecular sequencing enabled identification of P. micra.

Contrary to our suspicion that this febrile and tachycardic patient had a pulmonary embolism, she was later determined to have a septic embolus secondary to endocarditis. We highlight the difficulties in diagnosing certain cases of endocarditis in the emergency department, as well as the difficulties in distinguishing septic emboli from pulmonary emboli,especially with plain radiographs.

    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.

    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.

    Taubert, Kathryn A; Wilson, Walter

    2017-01-01

    Objectives Our purpose is to address whether antimicrobial prophylaxis is necessary before certain dental procedures for patients at increased risk for acquiring infective endocarditis (IE). Methods We reviewed recommendations for IE prophylaxis made by the American Heart Association (AHA) from 1995 to the present time. We also compared and contrasted the current recommendations from the AHA, European Society of Cardiology (ESC), United Kingdom’s National Institute for Health and Care Excellence (NICE) and a consortium of French organisations. We further reviewed recent papers that have observed the incidence of IE since these current recommendations were published. Results Beginning in the 1990s, questions were raised about the advisability of using antimicrobial prophylaxis before certain dental procedures to prevent IE. Various groups in Europe and the US were increasingly aware that there were not any clinical trials showing the effectiveness, or lack thereof, of such prophylaxis. In the early to mid-2000s, the AHA, ESC and French consortium published guidelines recommending restriction of prophylaxis before dental procedures to patients with highest risk for developing IE and/or the highest risk for an adverse outcome from IE. The NICE guidelines eliminated recommendations for prophylaxis before dental procedures. Studies published after these changes were instituted have generally shown that the incidence of IE has not changed, although two recent reports have observed some increased incidence (but not necessarily related to an antecedent dental procedure). Conclusion A multi-national randomised controlled clinical trial that would include individuals from both developed and developing countries around the world is needed to ultimately define whether there is a role for antibiotic prophylaxis administered before certain dental procedures to prevent IE.

    Repeat episodes of infective endocarditis (IE) can occur in patients who survive an initial episode. We analysed risk factors and 1-year mortality of patients with repeat IE. We considered 1874 patients enrolled in the International Collaboration on Endocarditis - Prospective Cohort Study between January 2000 and December 2006 (ICE-PCS) who had definite native or prosthetic valve IE and 1-year follow-up. Multivariable analysis was used to determine risk factors for repeat IE and 1-year mortality. Of 1874 patients, 1783 (95.2%) had single-episode IE and 91 (4.8%) had repeat IE: 74/91 (81%) with new infection and 17/91 (19%) with presumed relapse. On bivariate analysis, repeat IE was associated with haemodialysis (p 0.002), HIV (p 0.009), injection drug use (IDU) (p < 0.001), Staphylococcus aureus IE (p 0.003), healthcare acquisition (p 0.006) and previous IE before ICE enrolment (p 0.001). On adjusted analysis, independent risk factors were haemodialysis (OR, 2.5; 95% CI, 1.2-5.3), IDU (OR, 2.9; 95% CI, 1.6-5.4), previous IE (OR, 2.8; 95% CI, 1.5-5.1) and living in the North American region (OR, 1.9; 95% CI, 1.1-3.4). Patients with repeat IE had higher 1-year mortality than those with single-episode IE (p 0.003). Repeat IE is associated with IDU, previous IE and haemodialysis. Clinicians should be aware of these risk factors in order to recognize patients who are at risk of repeat IE.

    The purpose of this investigation was to examine whether Veillonella could cause transitory bacteriemia and endocarditis in both pure and mixed cultures when the port of entrance for infection was made in rats' incisors. Incisors of 54 male Zgr: whistar conventional rats were inoculated with pure culture of Veillonella (18 animals) and with mixed culture of S. mutans and Veillonella (18 animals). Remaining 18 incisors (the control group) were treated with saline solution. The animals were sacrificed after 7, 21 and 52 days respectively. Two positive hemocultures were obtained in mixed infection after 21 days of experimental procedure. Histopatological analysis of endocardial tissue revealed changes in 7 (12.96%) cases. Occurrence of acute endocarditis (one case) and chronical (four cases) ones depended on duration of mixed infections. For chronical endocarditis that appears in two animals with pure Veillonela culture we are at a loss of explanation. In conclusion, on the rats model Veillonella can penetrate into circulation in association with S. mutans via the pulp tissue and could be involved in infective endocarditis.

    Full Text Available Libman - Sacks endocarditis is the characteristic cardiac manifestation of autoimmune disease Systemic Lupus Erythematosus. The condition most commonly involves the mitral and aortic valves, but all the four cardiac valves and the endocardial surfa ces can be involved 1 . Persons with Libman - Sacks endocarditis are usually asymptomatic., but become symptomatic due to cardiac failure, cerebrovascular embolism, systemic thromboembolism and secondary infective endocarditis. 2D Echocardiography should be pe rformed when it is suspected. With introduction of steroid therapy for SLE, improved longevity of patients appears to have changed the spectrum of valvular disease. Herewith, we are reporting a 35 year old female who presented at Department of General Medi cine, GGH, Guntur with seven day history of anasarca, shortness of breath, cough and fever of long duration. ECHO was suggestive of Libman - Sachs endocarditis and further investigations revealed SLE. On addition of steroids, there was good response and the patient was improving, but she had sudden cardio - respiratory arrest 5 days later.

    Directory of Open Access Journals (Sweden)

    Teresa Semedo-Lemsaddek

    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.

    Francesco Puccio

    2008-11-01

    Full Text Available Primary aorto-duodenal fistula (PADF is a rare condition that may result in rapid exsanguination if untreated. PADF due to radiotherapy appears to be extremely rare with only a few cases reported in the medical literature. We report the case of a 61-year-old man who presented with massive gastrointestinal bleeding 25 years after surgery and radiotherapy for seminoma of the testicle and was successfully treated at our institution. We also review the literature on this very uncommon condition. A Medline search was conducted for the period from 1966 to June 2006 to identify case reports of PADF following radiotherapy. Only 7 cases of PADF due to radiotherapy were identified in addition to our own, 4 males and 3 females, aged 40 to 73 years, all treated for various forms of abdominal malignancies. The latency period ranged from 2 weeks to 25 years. None of the aortas were aneurysmatic. One patient died before he could be taken to the operating room. 5 patients underwent surgical repair and 4 survived. 2 patients underwent endovascular treatment but did not survive. PADF may develop up to 25 years after radiotherapy. Diagnosis should be considered when massive upper gastrointestinal bleeding develops in a patient who had previous abdominal radiotherapy, no matter how long before the episode of bleeding. Prompt surgical repair offers a reasonable chance of cure. Endovascular procedures do not appear to be efficacious.

    Full Text Available A terapia celular poderia ser conceituada de forma ampla e genérica como o emprego de células para tratamento de doenças. Apesar de um número não tão expressivo de relatos tendo o pulmão como objeto de estudo na terapia celular em pacientes humanos, há dados consistentes da literatura, tanto em humanos, quanto em modelos animais,que evidenciam a migração de células-tronco da medula óssea para o pulmão,em diferentes situações experimentais. Esses resultados forneceram o embasamento experimental para o emprego de células-tronco na regeneração do tecido pulmonar em modelos animais. Em nosso laboratório, vários projetos de pesquisa têm sido conduzidos com a finalidade de avaliar a resposta pulmonar (morfológica e funcional ao tratamento com células-tronco adultas em camundongos com doença pulmonar obstrutiva crônica (DPOC induzida experimentalmente. Os resultados obtidos, aliados àqueles de outros grupos de pesquisa, permitem aventar a possibilidade de aplicação, a curto prazo, da terapia celular em pacientes com DPOC. Em outra patologia pulmonar, fibrose cística (FC, cuja abordagem terapêutica com células-tronco apresenta aspectos particulares em relação às patologias pulmonares crônico-degenerativas, há avanços promissores e potencialmente interessantes; no entanto, os resultados podem ser considerados incipientes e deve-se assinalar, portanto, que a associação da terapia gênica e celular apresenta-se como uma alternativa possível, mas ainda muito distante quanto à sua consolidação e incorporação como opção terapêutica segura e eficaz em FC. Por outro lado, tendo por embasamento os resultados obtidos em modelos experimentais, é possível postular que a terapia celular com células-tronco hematopoéticas (ou de outras fontes encerra perspectivas consistentes de aplicação em diversas outras patologias pulmonares humanas, especialmente em DPOC.

La mayoría se diagnostican en pacientes con tumores avanzados, sobre todo localizados en mama, pulmón o estómago. Existen pocos casos publicados en pacientes con tumores uroteliales. Presentamos el caso de un varón de 69 años, sin diagnóstico previo de cáncer, que ingresó por disnea subaguda, con sospecha clínica inicial de tromboembolismo pulmonar (TEP. El paciente falleció al 5º día del ingreso. En la autopsia se comprobó la existencia de un tumor en pelvis renal izquierda con metástasis hepáticas y linfoganglionares múltiples y una extensa embolia pulmonar microvascular que afectaba a gran parte de los capilares y vasos sanguíneos de mediano calibre de ambos pulmones. Los ETP se consideraron responsables de la insuficiencia respiratoria progresiva y se interpretaron como la causa última de la muerte. La presentación clínica más frecuente de los ETP es la disnea, a menudo se confunden con el TEP y el diagnóstico no resulta fácil. Su pronóstico es muy malo, con una elevadísima mortalidad y su confirmación habitualmente es post-mortem.

Las primeras se refieren fundamentalmente al mal agudo de montaña y al edema cerebral de altura y las segundas al edema pulmonar agudo de montaña. Actuales evidencias señalan que el edema cerebral sería un fenómeno universal de los que ascienden a altura y que tres de cada cuatro individuos sanos que se expongan a altura desarrollarán un edema pulmonar agudo de montaña subclínico. La hipoxia de altura es la responsable de estos cuadros y los sujetos susceptibles serían aquellos que genéticamente tienen una respuesta ventilatoria reducida a la hipoxia y una exagerada respuesta vasopresora pulmonar al ejercicio.Se presenta un caso de edema pulmonar agudo de montaña en un deportista previamente sano que participó en una expedición al cerro El Plomo (5.280 msnm en la Cordillera de los Andes central. Posteriormente, se comenta la fisiopatología y tratamiento de esta condiciónHigh altitude diseases are originated from brain and lung. The first are Acute Mountain Sickness and Brain edema and the second is High Altitude Pulmonary Edema (HAPE. Current evidence shows that brain edema is an universal event of the people who are exposed to high altitude. By other hand 3 out of 4 healthy subjects exposed to high altitude will present a subclinical HAPE. Hypoxia of altitude is the responsable for this condition. The susceptible subjects would be those who genetically have a low ventilatory response to hypoxia and an exaggerated increase of vascular pulmonary pressure during exercise. A clinical case of acute pulmonary edema in a young sportman who participated in an expedition to Cerro El Plomo (5.280 m in Chilean Central Andes Mountains is presented.

    Staphylococcal endocarditis is potentially fatal and is now the most common cause of infective endocarditis with a mortality rate of 25-47% [Hecht SR, Berger M. Right-sided endocarditis in intravenous drug users: prognostic features in 102 episodes. Ann Intern Med 1992;117:560-6]. Its treatment requires maintenance of bactericidal level of antibiotics for prolonged periods to attain a culture-negative state. Although intravenous vancomycin is currently the drug of choice for methicillin resistant Staphylococcus aureus (MRSA) endocarditis, we present a case treated successfully with oral linezolid for 4 weeks due to a lack of venous access.

    Full Text Available The epidemiological and clinical study “Studio Endocarditi Italiane” (SEI evaluated 947 cases of infective endocarditis in 2004-2008. Enterococcal aethiology was described in 11% cases.The aim of our study was to evacuate the in vitro activity of twelve antibiotics alone and in association against 20 strains (15 E. faecalis, 5 E. faecium. Results show the in vitro activity of tigecyicline, daptomicine and linezolid. Synergism is appreciated for ceftriaxone-fosfomycin (FICindex50=0.34, FICindex90=0.56 against E. faecalis and for imipenem-fosfomycin against E. faecium.The majority of the tested strains show addition using ampicillin-ceftriaxone (FICindex50=0.85, FICindex90=1.01 and moxifloxacin- tigecycline (FICindex50=0.77, FICindex90=1.96.

    Full Text Available Bilateral endogenous endophthalmitis is a rare condition initiated by infection by microbes in the bloodstream, such as those arising from a foci of infective endocarditis. We report a case and discuss the diagnostic aspects and the clinical outcome of a patient with characteristic findings of the disease. The patient was a 49 year old white male who had a metallic aortic valve implanted 7 months previously, and who presented to the hospital with 10 days of fever, cough and dyspnea, then diarrhea and mental confusion. On the second day of hospitalization, he experienced sudden loss of vision in both eyes. A Gram-positive coccobacillus was isolated from the bloodstream, he was treated with fluoroquinolone with disappearance of fever, decreased ocular inflammation, and improvement in his vision to light perception. He later underwent valve replacement surgery but died during the procedure. We review the occurrence of ocular signs and symptoms and their importance in patients with endocarditis.

    Davenport, J; Hart, R G

    1990-07-01

    We retrospectively reviewed the clinical characteristics and outcomes of 61 patients with 62 episodes of prosthetic valve endocarditis, paying particular attention to neurologic complications (stroke). Atypical features of the group included a benign outcome of early postoperative infection (18% mortality) and a high stroke morbidity and mortality rate with Staphylococcus epidermidis infections. Eleven patients (18%) suffered an embolic stroke, most less than or equal to 3 days after diagnosis and before the initiation of antimicrobial therapy; the rate of embolic stroke recurrence was low (9%). The risk of embolic stroke was lower with bioprosthetic than with mechanical valves. No protective effect of anticoagulation therapy with warfarin was observed. Six patients (8%) suffered brain hemorrhage due to septic arteritis, brain infarction, or undetermined causes; no specific risk of hemorrhagic stroke was evident with anticoagulation therapy. Antibiotic treatment appears to be more important than anticoagulation to prevent neurologic complications in patients with prosthetic valve endocarditis.

    The study included 62 patients with uncomplicated primary and secondary infectious endocarditis admitted to S.PBotkin city hospital from 2011 to 2014. The emphasis is laid on diagnostic significance of dynamic measurements of the levels of C-reactive protein, tumour necrosis factor and highly sensitive troponin-1 for the evaluation of activity of the infectious/toxic process, severity of the disease, and detection of complications. The study revealed the relationship of the enhanced level of troponin-1 with changes of inflammation markers, morphofunctional characteristics of myocardium, and circulatory failure. Morphologicl study demonstrated inflammatory and dystrophic changes in myocardium, focal and diffuse cardiofibrosis suggesting development of non-coronarogenic myocardial lesions that play an important role in the progress of cardiac failure associated with infectious endocarditis.

    Research in different topics in cardiovascular medicine is evolving rapidly. However, this is not the case for endocarditis, despite its being the cardiovascular disease with the highest mortality and, at the same time, the entity with relatively less scientific evidence supporting its treatment. Many problems are delaying research: it is an uncommon disease, few multicenter registries are ongoing, financing for research in this topic is lacking, randomization is costly, difficult, and considered unethical by some, and conclusions coming from propensity score analysis are taken as if they came from randomized trials. In this review, we put forward the main issues in need of evidence and propose a different approach to advance the understanding of left-sided infective endocarditis. We summarize the limited evidence available, the questions that are pending, and how we should proceed to answer them.

    A 73-year-old woman with breast cancer and metastasis under chemotherapy suffered from fever, pleural effusion and pericardial effusion. Despite the administration of treatment with cefozopran and prednisolone, the patient's fever relapsed. An electrocardiogram identified a new complete atrioventricular block and an echocardiogram revealed vegetation with an unusual pseudotumoral mass in the right atrium. Blood cultures grew Listeria monocytogenes. The patient was eventually diagnosed with right-sided infective endocarditis, which improved following the six-week administration of ampicillin and gentamicin. Homemade yoghurt was suspected to be the cause of infection in this case. Listeria endocarditis is rare; however, physicians should pay more attention to preventing this fatal disease in immunocompromised patients.

    Approximately 10% of infective endocarditis (IE) involves the right side of the heart with the majority of these cases occurring in intravenous drug users. Patients are less likely to present with classical IE signs of a new murmur and peripheral stigmata, are more frequently immunocompromised and often have significant social difficulties. These factors result in both diagnostic and therapeutic challenges in this patient group that are not often seen in other patient populations with IE.

    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.

    Objective To analyze the clinical features of hemodialysis patients complicated by infective endo-carditis.Methods The clinical features of six such patients admitted to Peking Union Medical College Hos-pital during the year 1990 to 2009 were analyzed. All of them were diagnosed based on Chinese Children Diagnostic Criteria for Infective Endocarditis.Results The average age of the six patients was 52.3±19.3 years old. Four were males. Vascular ac-cesses at the onset of infective endocarditis were as follows: permanent catheters in three, temporary cathe-ters in two, and arteriovenous fistula in one. Three were found with mitral valve involvement, two with aor-tic valve involvement, and one with both. Five vegetations were found by transthoraeic echocardiography, and one by transesophageal echocardiography. Four had positive blood culture results. The catheters were all removed. Four of the patients were improved by antibiotics treatment, in which two were still on hemodialy-sis in the following 14-24 months and the other two were lost to follow-up. One patient received surgery, but died of heart failure after further hemodialysis for three months. One was well on maintenance hemodi-alysis for three months after surgery.Conclusions Infective endocarditis should be suspected when hemodialysis patients suffer from long-term fever, for which prompt blood culture and transthoracic echocardiography confirmation could be performed. Transesophageal echocardiography could be considered even when transthoracic echocardiogra-phy produces negative findings. With catheters removed, full course of appropriate sensitive antibiotics and surgery if indicated could improve the outcome of chronic hemodialysis patients complicated by infective endocarditis.

  13. A Case of Systemic Lupus Erythematosus Confused with Infective Endocarditis

    Directory of Open Access Journals (Sweden)

    Sibel Serin

    2014-09-01

    Full Text Available Systemic lupus erythematosus (SLE is a multisystemic autoimmune disease resulting from immune system-mediated tissue damage. Clinical findings of SLE can involve skin, kidney, central nervous system, cardiovascular system, serosal membranes, and the hematologic and immune systems. In the differential diagnosis, other connective tissue diseases, infective endocarditis, infections such as viral hepatitis, endocrine disorders such as hypothyroidism, sarcoidosis, and some malignant tumors should be considered. Infective endocarditis can imitate all the symptoms of SLE depending on immune complex accumulation glomerulonephritis. Hemolytic anemia, skin lesions, arthralgia, arthritis, decreased complement levels, and autoantibody positivity, including antinuclear autoantibody (ANA, positivity can be seen. Therefore, high fever, blood cultures, eye examination, and echocardiographic findings are of particular value. Here, we present a case of SLE that was confused with infective endocarditis (IE due to the presence of high fever associated with autoimmune hemolytic anemia (AHA and proteinuria as well as increased erythrocyte sedimentation rate (ESR, cardiac murmur, and Roth’s spots.

    2014-01-01

    The frequency of superantigen production among Staphylococcus aureus isolates associated with endocarditis is not well defined. We tested 154 S. aureus isolates from definite infective endocarditis cases for the presence of staphylococcal enterotoxins A-E, H and TSST-1 by PCR, ELISA and using an HLA-DR3 transgenic mouse splenocyte proliferation assay. Sixty-three isolates (50.8%) tested positive for at least one superantigen gene, with 21 (16.9%) testing positive for more than two. tst (28.6%) was most common, followed by seb (27%), sea (22.2%), sed (20.6%), see (17.5%), and sec (11.1%). Of 41 methicillin-resistant S. aureus, 21 had superantigen genes, with sed being more frequently detected in this group compared to methicillin-susceptible S. aureus (P<0.05). Superantigen genes were not associated with mortality (P=0.81). 75% of PCR-positive isolates induced robust splenocyte proliferation. Overall, more than half of S. aureus isolates causing endocarditis carry superantigen genes of which most are functional. PMID:24745820

  15. Complications of Candidemia in ICU Patients: Endophthalmitis, Osteomyelitis, Endocarditis.

    Science.gov (United States)

    Kauffman, Carol A

    2015-10-01

    Bloodstream infection with Candida species is not uncommon in the intensive care unit setting and has the potential to distribute organisms to many different organ systems causing secondary infections, such as endophthalmitis, osteomyelitis, and endocarditis. In some patients, these types of infections become manifested shortly after the episode of candidemia. In others, especially vertebral osteomyelitis, weeks pass before the diagnosis is entertained. Endophthalmitis should be sought by a retinal examination in all patients early after an episode of candidemia. Both osteomyelitis and endocarditis are less common complications of candidemia than endophthalmitis. In patients who manifest symptoms or signs suggesting these infections, magnetic resonance imaging and transesophageal echocardiography, respectively, are extremely helpful diagnostic tests. Newer approaches to the treatment of these infections allow the use of better tolerated, safer antifungal agents. Endophthalmitis is often treated with fluconazole or voriconazole, and the echinocandins are increasingly used, instead of amphotericin B, as initial therapy for osteomyelitis and endocarditis before step-down therapy to oral azole agents.

    Bartonella spp. are increasingly implicated in infectious endocarditis cases in the UK. Herein, we attempted to quantify their role in this syndrome and explored the epidemiology of Bartonella-associated endocarditis in the UK. Between November 2005 and October 2010, samples from 685 endocarditis patients were submitted to the Health Protection Agency for Bartonella serology. Serological evidence of infection was obtained for 57 (8·3%) patients. PCR-based evidence of infection was obtained from 13 out of 14 patients for whom heart valve tissue was available, with Bartonella quintana implicated in 12 cases and B. henselae in one. Six patients with B. quintana endocarditis were recent immigrants into the UK, of whom four lived in poor socioeconomic conditions. These results indicate that Bartonella is a not uncommon cause of endocarditis in the UK and should be considered particularly in patients raised in eastern Europe and/or with a history of homelessness or alcoholism.

    We describe a case of infective endocarditis in a 33 year old patient, with mitral valve prolapse (MVP), who underwent nine attempts of artificial insemination with semen by donor. Several blood cultures demonstrated the presence of Enterococcus faecalis; the same agent was identified in some vaginal cultures. Despite antibiotic therapy, infective endocarditis was complicated by severe mitral regurgitation, followed by the rupture of a chorda tendinea. The patient underwent cardiac surgery: valvuloplasty of posterior mitral cusp, chordae tendineae in Goretex and anulus reinforcement with autologous pericardium. MVP is the most common heart disease associated with infective endocarditis in non-drug addict patients (32-54%). The review of the literature did not show any other case of infective endocarditis after artificial insemination procedures. Because of the large spread of these procedures, we think antibiotic prophylaxis of infective endocarditis should be considered in patients with MVP.

MÉTODOS: Foram utilizados 137 ratos "Wistar", machos, subnutridos pela oferta de 33% da ingestão diária normal na fase de adaptação e durante o experimento, distribuídos por sorteio, em 9 grupos experimentais, submetidos a três tratamentos (Controle, Toracotomia, Trilobectomia e sacrificados em três momentos (7, 30 e 90 dias. Na Trilobectomia foram extirpados os lobos médio, acessório e caudal direitos, que representavam 55% do tecido pulmonar. Estudou-se os seguintes atributos e variáveis: massa corpórea e pulmonar, relação entre massa pulmonar e corpórea e conteúdos protéicos pulmonares. RESULTADOS: No lobo cranial e no pulmão esquerdo, tanto a massa quanto os conteúdos protéicos, nos trilobectomizados, foram maiores em todos os momentos do estudo quando comparados aos demais, sendo este aumento suficiente para compensar a perda dos três lobos. Os conteúdos protéicos do lobo cranial e do pulmão esquerdo, nos trilobectomizados, tiveram o mesmo comportamento da massa pulmonar, mas este aumento não foi suficiente para compensar a perda dos três lobos. CONCLUSÕES: Nos ratos adultos subnutridos trilobectomizados ocorre CPC. A recuperação da massa pulmonar é total, mas o conteúdo protéico pulmonar apesar de aumentar, não chega aos valores dos ratos não trilobectomizados.

    The extent to which prescribed antimicrobial prophylaxis against bacterial endocarditis conformed with American Heart Association (AHA) guidelines was determined and the frequency of nonconformity with specific elements of the guidelines was evaluated. Patients with conditions defined by AHA as placing them at risk for developing endocarditis were identified through medical records for a four-year period at an 850-bed hospital. Data about the procedures they underwent and prophylaxis prescribed were compared with the AHA guidelines. Conformity with the guidelines was evaluated according to whether prophylaxis was recommended, optional, or unnecessary; nonconformity with specific elements of the guidelines (indication, choice of antimicrobial, dose, dosage interval, timing, and duration) was also evaluated. The following variables were evaluated for possible association with nonconformity to the guidelines: patient's age and sex, penicillin allergy, use of a consultant, and whether the procedure was the first performed in the patient after identification of the cardiac condition. Of the 131 cases analyzed, 29 (22%) involved prophylaxis that conformed with the AHA guidelines. Conformity with the guidelines was significantly lower when prophylaxis was recommended or optional than when it was unnecessary. Nonconformity was most common with the following elements: indication, choice of antimicrobial, and dose. Recommended prophylaxis was given more often in children than in adults and more often before first procedures than before subsequent procedures. More of the regimens prescribed for children exceeded the recommended duration than those prescribed for adults. Unnecessary prophylaxis was given more often when a consultant was involved than when no consultant was involved. In hospitalized patients, conformity with AHA guidelines for antimicrobial prophylaxis against endocarditis was low.

    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.

    Kingella kingae is part of the nonpathogenic flora normally found in the oral cavity and pharynx. Recent reports have established that K. kingae can cause invasive infections in pediatric patients. Few cases have been described in adults, however. We report a case of K. kingae arthritis of the knee followed by endocarditis in a 59-year-old woman. Physicians and microbiologists should be alert to the possibility of K. kingae infection. K. kingae is easy to detect provided its specific culture requirements are taken into account. Synovial fluid inoculation into blood culture vials considerably increases the likelihood of K. kingae recovery in patients with septic arthritis.

    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. Conversely, an obstructive

    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.

    Background: Q fever endocarditis, a chronic illness caused by Coxiella burnetii, can be fatal if misdiagnosed or left untreated. Despite a relatively high positive rate of Q fever serology in healthy individuals in the mainland of China, very few cases of Q fever endocarditis have been reported. This study summarized cases of Q fever endocarditis among blood culture negative endocarditis (BCNE) patients and discussed factors attributing to the low diagnostic rate. Methods: We identified confirmed cases of Q fever endocarditis among 637 consecutive patients with infective endocarditis (IE) in the Peking Union Medical College Hospital between 2006 and 2016. The clinical findings for each confirmed case were recorded. BCNE patients were also examined and each BCNE patient's Q fever risk factors were identified. The risk factors and presence of Q fever serologic testing between BCNE patients suspected and unsuspected of Q fever were compared using the Chi-squared or Chi-squared with Yates’ correction for continuity. Results: Among the IE patients examined, there were 147 BCNE patients, of whom only 11 patients (7.5%) were suspected of Q fever and undergone serological testing for C. burnetii. Six out of 11 suspected cases were diagnosed as Q fever endocarditis. For the remaining136 BCNE patients, none of them was suspected of Q fever nor underwent relevant testing. Risk factors for Q fever endocarditis were comparable between suspected and unsuspected patients, with the most common risk factors being valvulopathy in both groups. However, significantly more patients had consulted the Infectious Diseases Division and undergone comprehensive diagnostic tests in the suspected group than the unsuspected group (100% vs. 63%, P = 0.03). Conclusions: Q fever endocarditis is a serious yet treatable condition. Lacking awareness of the disease may prevent BCNE patients from being identified, despite having Q fever risk factors. Increasing awareness and guideline adherence are

    Vancomycin is currently the drug of choice in meticillin-resistant Staphylococcus aureus (MRSA) infection. It is also used prophylactically in some situations in which the patient is at risk for endocarditis. It is often used in combination with other antibacterials in the treatment of endocarditis and is a potential nephrotoxin. Various consensus guidelines differ in their interpretation of vancomycin plasma concentrations. This paper describes a case of a 72-years old Caucasian female patient, who developed significant renal impairment when prescribed vancomycin in combination with penicillin for the treatment of endocarditis, caused by Streptococcus pneumoniae.

    2014-10-01

    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.

    Staphylococcus lugdunensis is part of the native flora in the inguinal region of the body. Inguinal surgeries, such as vasectomy, place carriers of this aggressive pathogen at risk for contamination. Native-valve endocarditis caused by coagulase-negative S. lugdunensis has a rapid and complicated clinical course. The pathogenicity of this organism is not limited to cardiac valvular destruction. We report the case of a 36-year-old man who presented with S. lugdunensis endocarditis, dysarthria, and hemiparesis 5 weeks after a vasectomy. To our knowledge, this is the first report of embolic stroke caused by S. lugdunensis endocarditis. In addition, we discuss the relevant medical literature.

    Coagulase-negative staphylococci (CNS) are important causes of infective endocarditis (IE), but their microbiological profiles are poorly described. We performed DNA target sequencing and susceptibility testing for 91 patients with definite CNS IE who were identified from the International Collaboration on Endocarditis-Microbiology, a large, multicenter, multinational consortium. A hierarchy of gene sequences demonstrated great genetic diversity within CNS from patients with definite endocarditis that represented diverse geographic regions. In particular, rpoB sequence data demonstrated unique genetic signatures with the potential to serve as an important tool for global surveillance.

We report a case of culture-negative endocarditis with serious complications due to S. tigurinus, which was identified by 16S ribosomal RNA gene sequence analysis of excised valve tissue specimens. This technique is useful for identification of the causative microorganism in patients with culture-negative endocarditis and may facilitate early diagnosis and appropriate antimicrobial treatment.

    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 Infective endocarditis is defi ned as an infection of the endocardial surface of the heart. Its intracardiac effects include severe valvular insuffi ciency, which may lead to intractable congestive heart failure and myocardialabscesses. This disease still carries a poor prognosis and a high mortality.A severe case of infective endocarditis with its complications is presented. A man with aortic prosthetic valve due to earlier aortic stenosis and corrected aortal coarctation and implanted pacemaker presentedwith prolonged unexplained fever, malaise, sweating, weight loss (15 kg/4 months and lumbar pain. He was treated with broad-spectrum antibiotics prior IE diagnosis was considered. Echocardiogram showedaortic vegetations and possible periaortal abscess formation. Nonspecifi c infl ammation parameters were high positive. Cultures were constantly negative. His condition had deteriorated suddenly, and he had presentedwith worsening of cutaneous vasculitis, subacute glomerulonephritis and subsequent acute respiratory distress syndrome and septic shock. This patient survived with residual bilateral necrosis of the feet andtoxic peroneal paresis. At the end transthoracic echocardiogram showed enlarged heart chambers, LV mild dilated and concentric hypertrophy with ejection fraction about 40%, degenerative postinfl ammatory mitralvalve changes, mild mitral regurgitation and tricuspid regurgitation, postinfl ammatory aortic root fi brosis and moderate aortic valve stenosis (AVPG max 50,9 mmHg, AVPG mean 24 mmHg with no pericardial effusion. Initial suspicion of Q fever was defi nitely excluded by serological testing showing nonspecifi c IgM positivity,probably rheumatoid factor related.

    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. Antibiotic prophylaxis in infective endocarditis: Use or abuse?

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Introduction: The American Heart Association (AHA recommendations for antimicrobial prophylaxis for infective endocarditis (IE are controversial. According to the new guidelines released by the AHA now, the only patients to receive antibiotics will be those at highest risk, i.e. those with a prosthetic heart valve, a history of endocarditis, certain forms of congenital heart disease or valvulopathy after heart transplantation, and only before certain dental procedures. Unfortunately, these guidelines are still based largely on expert opinion, with very little hard evidence to show that antibiotic therapy actually prevents IE. The Hypothesis: The reported incidence of bacteremia during dental intervention ranges from 10% to 100% and, with daily brushing and flossing, from 20% to 68%. Because bacteremia also occurs during brushing and flossing of teeth, why give prophylaxis just for dental procedures? Moreover, the risks of causing adverse or anaphylactic reactions from antibiotics as well as contributing to the nationwide antibiotic resistance problem are issues not to be taken lightly. Evaluation of the Hypothesis: The hypothesis discusses the AHA recommendations for antimicrobial prophylaxis for IE, indicating some inherent limitations associated with it, and stresses upon the fact that these recommendation should also be updated, if not completely changed, to cope up with the advancements in the proper treatment plan.

    Objective To discuss thepathogenesis, etiology, clinical manifestations, diagnosis, treatment and prognosis of right-sided infective endocarditis (RIE) . Methods To investigate retrospectively the clinical data of patients with RIE admitted in our hospital from Jan 1985 to Dec 2000.Results There were 17 cases of RIE (12 male, 5female, mean age 22 years), among which 7 with congenital heart disease, 1 with pacemaker implantation and 9 with a history of intravenous drug abuse but without underlying heart disease. Fever and multiple pulmonary emboli were the major clinical manifestations. Blood cultures were positive in 8 cases with Staphylococcus aureus as the predominant microorganism. Echocardiography detected right heart vegetations in all cases, with tricuspid valve as the structure most frequently affected. Most patients were successfully treated with antimicrobials. The outcome was favourable, with a mortality of 11.8 % . Conclusions The clinical features of RIE are different from that of left-sided infective endocarditis (LIE) . Echocardiography plays an important role in the diagnosis of RIE.

    Objectives: The objective of this study is to assess the knowledge and practice of dentists from Jordan, regarding prevention of infective endocarditis (IE) in dental practice. Materials and Methods: A sample of Jordanian dentists was interviewed regarding their IE knowledge and practice using a validated and pretested survey instrument. Results: Most of the dentists have encountered a patient with IE who needed prophylactic antibiotic (PA) and have prescribed antibiotics to prevent IE. Jordanian dentists’ approach to patients in need for PA varied between the National Institute for Health and Clinical Excellence recommendations and the American Heart Association to a lesser degree, but still a relatively high percent (39%) did not know any guidelines to follow although 74% have encountered patients who needed endocarditis prophylaxis. Patients with prosthetic heart valve were ranked on top of medical conditions that required PA (87.4%), and most dentists (94.5%) thought that dental extractions need PA followed by periodontal surgery (88.2%). Conclusion: There is a lack of consistency in the knowledge and practice of Jordanian dentists with regard to IE. There is a need to take actions to improve dentist's knowledge regarding this topic.

    2015-01-01

    Full Text Available 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.

    Full Text Available Despite advances in therapy, infective endocarditis (IE remains a serious disease with high mortality. We evaluated 155 Egyptian patients with Duke definite/possible IE to determine incidence, causes and predictors of inhospital mortality. The mean time from symptoms onset to diagnosis was 66.4 ± 97 days. The causes of mortality (38.7% included congestive heart failure (CHF, sepsis, surgery related, stroke, cerebral hemorrhage, pulmonary embolism, sudden cardiac death, and hyperkalemia. Predictors of mortality on univariate analysis were duration of symptoms before hospital admission (p = 0.017, health care associated endocarditis (p = 0.039, CHF (p < 0.001, fulminant sepsis (p < 0.001, embolization (p = 0.011, need for dialysis (p = 0.003, need for cardiac surgery (p = 0.027, unperformed indicated cardiac surgery (p = 0.002 and higher C-reactive protein level (p = 0.05. In multivariate analysis, only CHF remained an independent predictor of mortality (p = 0.033. IE mortality was high in this cohort probably due to delayed diagnosis. Patients having these mortality predictors especially CHF deserve more aggressive treatment.

    Usually, cardiac calcifications are observed in aortic and mitral valves, atrio-ventricular plane, mitral annulus, coronary arteries, pericaridium(usually causing constrictive pericarditis) and cardiac masses. Calcifications of atrial walls are unusual findings that can be identified only using imaging with high spatial resolution, such as cardiac magnetic resonance and computed tomography. We report a case of a 43-year-old patient with no history of heart disease that underwent cardiac evaluation for mild dyspnoea. The echocardiogram showed a calcific aortic valve and a hyper-echogenic lesion located in atrio-ventricular plane. The patient was submitted to cardiac magnetic resonance and to computed tomography imaging to better characterize the localization of mass. The clinical features and location of calcified lesion suggest an infective aetiology causing an endocarditis involving the aortic valve, atrioventricular plane and left atrium. Although we haven’t data to support a definite and clear diagnosis, the clinical features and location of the calcified lesion suggest an infective aetiology causing an endocarditis involving the aortic valve, atrio-ventricular plane and left atrium. The patient was followed for 12 mo both clinically and by electrocardiogram and echocardiography without worsening of clinical, electrocardiographic and echocardiographic data. Cardiac magnetic resonance imaging and computed tomography are ideal methods for identifying and following over time patients with calcific degeneration in the heart.

    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.

O diagnóstico é suspeito em casos de endocardite sem resposta ao tratamento comum e é confirmado com sorologia com teste de ELISA maior que 1:160. O tratamento na maioria dos casos é cirúrgico, associado a antibioticoterapia prolongada. Alguns casos são resolvidos com tratamento clínico, que inclui doxiciclina, rifampicina, ciproproxacina, gentamicina e tetraciclina. O objetivo deste estudo foi relatar um caso raro de endocardite por brucelose. RELATO DO CASO: Paciente do sexo masculino, 51 anos, trabalhador rural, admitido com quadro de febre e emagrecimento. O ecocardiograma mostrou espessamento e vegetação de válvula aórtica. Uma hemocultura foi positiva para Staphylococcus epidermidis. O tratamento foi iniciado no dia da internação com penicilina cristalina, associada com garamicina, sem melhora em três semanas. Foi suspeitada endocardite por brucelose, colhida sorologia e iniciado o tratamento. Os antibióticos usados foram rifampicina e ciprofloxacin associado à vancomicina, devido o resultado da primeira hemocultura. A sorologia de aglutinação para brucelose foi positiva com resultado de 1:360. O paciente melhorou e recebeu alta da UTI, hemodinamicamente estável e em uso de ciprofloxacin e gentamicina. CONCLUSÕES: A endocardite por brucelose não é comum, mas deve ser sempre lembrada quando o tratamento convencional de endocardite não tem boa resposta, principalmente nos pacientes com possível contato com animais e derivados de leite.BACKGROUND AND OBJECTIVES: Endocarditis is a rare and serious complication of human brucellosis.

    Full Text Available The association between spondylodiscitis and endocarditis was first reported in 1965 by de Sèze et al. The most common clinical picture of this association is musculoskeletal symptoms preceding endocarditis diagnosis, but we report here a case of spondylodiscitis complicating endocarditis in its late course. A 70-year-old man, with an established diagnosis of mitral valve endocarditis caused by Streptococcus intermedius, early submitted to surgical treatment because of heart failure, who had an uneventful recovery up to the 12th day of antibiotic therapy when he presented intensive backache, with tenderness in the two lower lumbar vertebras. Spondylodiscitis was confirmed by a magnetic resonance imaging and the treatment was non-esteroidal anti-inflamatory and analgetics drug, with good results, and prolongation of antibiotic treatment up to 3 months. Appropriate diagnosis of this association has important consequences, as the need of a longer antibiotic therapy course, which can range from 6 weeks to 3 months.

    Streptococcus agalactiae, commonly known as Group B streptococcus (GBS), was originally discovered as a cause of bovine mastitis. GBS colonizes the genital tract of up to 40% of women and has become a major pathogen in neonatal meningitis. GBS endocarditis is thought to be an uncommon manifestation of this infection and carries a higher mortality compared to other streptococcal pathogens. Studies have shown that endocarditis after abortion has an incidence of about one per million. However, this figure was published prior to routine use of echocardiography for diagnosis. The American Heart Association has recently declared transesophageal echocardiography the gold standard for endocarditis diagnosis. This case report illustrates that, given the potentially devastating consequences of endocarditis, there is a need for updated studies to adequately assess the true incidence of this infection. Pending the outcome of these studies, routine GBS screening and prophylactic antibiotics prior to abortion should be recommended.

    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. This was an extremely rare case in which S. agalactiae of ST19 caused very severe endocarditis in an adult patient with no underlying disease.

    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.

    Mural endocarditis is a rare clinical entity with an extremely high mortality rate. It is usually predisposed by an underlying structural intracardiac abnormality. We present two cases of mural endocarditis occurring in the right atrium which were complicated by septic pulmonary embolism, one of which was predisposed by a jet lesion secondary to a coronary artery fistula. Both cases were successfully managed conservatively with excellent long-term outcomes.

    In developed countries, Corynebacterium diphtheriae infection is rare due to efficient immunization programs. However, cases of nontoxigenic strains of C. diphtheriae infections, including endocarditis, have been reported recently. Although the incidence remains low, these infections are associated with high morbidity and mortality. This report describes the first and atypical case of bacteremia and endocarditis caused by nontoxigenic C. diphtheriae var. gravis after introduction of immunization in the Kingdom of Saudi Arabia (KSA).

    A 22-year-old man had severe pulmonary congestion and required mechanical ventilation. Endocarditis was suspected because a 2/6 systolic murmur was heard at the apex and because Osler nodes were present. Transthoracic and transesophageal echocardiography allowed correct diagnosis of papillary muscle rupture causing massive mitral regurgitation. To our knowledge, this is the first reported case of papillary muscle rupture caused by bacterial endocarditis diagnosed by transthoracic and transesophageal echocardiography.

    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.)

    Full Text Available We present a case of successful repair of the mitral valve for active infective endocarditis. Mitral valve repair was performed through debridement of vegetation and abscess, resection and repair of the posterior mitral leaflet and posterior repair with autologous pericardium. Postoperative period was uneventfully, with no evidence of recurrent infection, and echocardiogram showed mitral valve competence with mild mitral regurgitation. We demonstrate that valve repair is a feasible choice in cases of active endocarditis in children.

    A case is reported of prosthetic valve endocarditis due to Neisseria elongata subsp. elongata in a patient with Klinefelter's syndrome. This is believed to be only the third case of endocarditis reported due to this subspecies. N. elongata is difficult to identify, and is morphologically and biochemically similar to Kingella spp. Sequencing of the 16S rRNA gene is useful for identification. The patient was successfully treated with amoxicillin and gentamicin, followed by ceftriaxone.

    2010-08-01

    Full Text Available Abstract Introduction 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. Case presentation 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. Conclusion 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.

  19. Anti-fibrin antibody binding in valvular vegetations and kidney lesions during experimental endocarditis.

    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.

    Right heart endocarditis makes up 5-10% of all infective endocarditis involving valvular, congenital and artificial structures. Given the limited literature in this area, we reviewed the characteristics, management and outcomes of this condition in this retrospective cohort study. Thirty-five patients with right heart endocarditis admitted to Auckland City Hospital during 2005-2010 were followed-up for 3.4+/-2.5 years. In-hospital mortality was 11.4% (4), all occurring in those treated medically (20.0% (4) vs 0.0% (0), P=0.119). Surgical intervention was independently associated with reduced long-term mortality (HR 0.078, 95%CI 0.010-0.609, P=0.015) in multivariate analysis, while concurrent left heart endocarditis predicted both in-hospital mortality (HR 11.0, 95%CI 1.18-102, P=0.027) and long-term mortality (HR 3.20, 95%CI 1.03-9.92, P=0.044). Our study showed that surgical intervention and concomitant left heart endocarditis are positive and negative prognostic factors for outcomes after right heart endocarditis.

    Full Text Available Infective endocarditis (IE, an infection of the endocardium that usually involves the valves and adjacent structures, may be caused by a wide variety of bacteria and fungi that entered the bloodstream and settled in the heart lining, a heart valve or a blood vessel. The IE is uncommon, but people with some heart conditions have a greater risk of developing it. Despite advances in medical, surgical, and critical care interventions, the IE remains a disease that is associated with considerable morbidity and mortality. Hence, in order to minimize the risk of adverse outcome and achieve a yet better management of complications, it is crucial to increase the awareness of all the prophylactic measures of the IE.

    This case highlights the diagnostic challenges in patients presenting with bilateral sudden sensorinueral hearing loss (SNHL). The aetiology of bilateral sudden SNHL may span several medical disciplines. Therefore, clinicians should be mindful of such presentations, and consider aetiologies beyond otological and neurological causes. We present a case of a previously healthy 51-year-old woman who presented with coryzal symptoms and sudden audiovestibular failure. Examination revealed fever, tachycardia, bilateral profound hearing loss and nystagmus. Following investigations, an initial working diagnosis of vasculitis was made. Later, blood cultures revealed methicillin-sensitive Staphylococcus aureus (MSSA) and a transoesophageal echocardiogram confirmed endocarditis. The patient made a good recovery, but the hearing loss was permanent and managed with a cochlear implant.

    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.)

    2014-03-01

    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.

    BACKGROUND: Transcatheter aortic valve implantation (TAVI) is an advancing mode of treatment for inoperable or high-risk patients with aortic stenosis. Prosthetic valve endocarditis (PVE) after TAVI is a serious complication, but only limited data exist on its incidence, outcome, and procedural...... risk factors. METHODS AND RESULTS: Observational single-center study of 509 consecutive patients treated with a transcatheter implanted self-expandable aortic valve prosthesis (Medtronic CoreValve). We identified 18 patients diagnosed with TAVI-PVE during a median follow-up period of 1.4 years...... (interquartile range, 0.5-2.5 years; longest follow-up was 6.3 years). TAVI-PVE was most frequent in the first year after implantation (first-year incidence, 3.1% [confidence interval, 1.4%-4.8%]); the overall annualized rate was 2.1% per patient-year (confidence interval, 1.2%-3.3%).

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 E apresentado um caso de adiaspiromícose pulmonar disseminada, em paciente oriundo de Corrente, Estado do Piauí. Trata-se do segundo caso dessa forma clínica diagnosticado no Distrito Federal. As manifestações principais consistiram em febre, calafrios, tosse e dispnéia. Com dez meses da doença, veio o paciente à consulta, motivado por exacerbação dos sintomas ocorrida cerca de dois meses antes. Após toracotomia direita, numerosas lesões nodulares, brancas, miiiares, aparecem disseminadas por toda a superfície exposta do órgão. O exame microscópico de um fragmento do pulmão permitiu reconhecer-se a presença de microabscessos e granulomas, alguns contendo no seu interior estruturas redondas, queforam identificadas como adiaconidios de Chrysosporium parvum var. crescens. O aspecto variado das lesões foi considerado por representar estádios evolutivos diferentes do processo inflamatório, estando a variação ligada a inóculos diversos do fungo, separados no tempo. Admite-se que a exacerbação, referida pelo paciente, resultou de uma nova exposição ao fungo, sugerida pela existência de lesões recentes, de natureza supurativa, entre outras, de aspecto granulomatoso, tidas como mais antigas.

    OBJECTIVE—To analyse the long term results of mechanical prostheses for treating active infective endocarditis.
DESIGN—Prospective cohort study of a consecutive series of patients diagnosed with infective endocarditis and operated on in the active phase of the infection for insertion of a mechanical prosthesis.
SETTING—Tertiary referral centre in a metropolitan area.
RESULTS—Between 1975 and 1997, 637 cases of infective endocarditis were diagnosed in the centre. Of these, 436 were left sided (with overall mortality of 20.3%). Surgical treatment in the active phase of the infection was needed in 141 patients (72% native, 28% prosthetic infective endocarditis). Mechanical prostheses were used in 131 patients. Operative mortality was 30.5% (40 patients). Ninety one survivors were followed up prospectively for (mean (SD)) 5.4 (4.5) years. Thirteen patients developed prosthetic valve dysfunction. Nine patients suffered reinfection: four of these (4%) were early and five were late. The median time from surgery for late reinfection was 1.4 years. During follow up, 12 patients died. Excluding operative mortality, actuarial survival was 86.6% at five years and 83.7% at 10 years; actuarial survival free from death, reoperation, and reinfection was 73.1% at five years and 59.8% at 10 years.
CONCLUSIONS—In patients surviving acute infective endocarditis and receiving mechanical prostheses, the rate of early reinfection compares well with reported results of homografts. In addition, prosthesis dysfunction rate is low and long term survival is good. These data should prove useful for comparison with long term studies, when available, using other types of valve surgery in active infective 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 Pl(A1/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 Pl(A1/A1) genotype had increased in vivo platelet activation (P = 0.001). Furthermore, neither GPIIIa Pl(A1/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.

    Full Text Available O presente estudo teve como objetivo verificar a viabilidade do n-butil cianoacrilato na pneumostasia e hemostasia em lobectomia pulmonar parcial. Foram utilizadas seis gatas hígidas, adultas, com peso médio de três quilogramas. O procedimento cirúrgico consistiu na realização de toracotomia intercostal com lobectomia pulmonar parcial em que se utilizou adesivo cirúrgico para fechamento do lobo pulmonar. Após 21 dias da cirurgia, os animais foram novamente submetidos à toracotomia para a coleta de fragmento da região onde o adesivo fora aplicado, para análise histopatológica. Foram realizadas radiografias de tórax das pacientes para o acompanhamento pré e pós lobectomia pulmonar parcial e, aos dois, sete, 14 e 21 dias subseqüentes. As alterações radiográficas e clínicas encontradas como pneumotórax residual, aumento na densidade pulmonar, enfisema subcutâneo e apatia foram corrigidas em tempo hábil, não comprometendo os resultados do estudo. A histopatologia evidenciou reação inflamatória com predomínio de células mononucleares, neovascularização, proliferação de tecido conjuntivo e pequenas áreas de enfisema e atelectasia, sem comprometimento clínico significativo. Concluiu-se que o cianoacrilato é capaz de produzir adequada pneumostasia e hemostasia, e poderá ser uma opção para a realização de lobectomia pulmonar parcial em felinos.

    We have preferably utilized monocusp valved outflow patch (MVOP) for right ventricular outflow tract (RVOT) reconstruction in pulmonary atresia with ventricular septal defect (PA + VSD). The purpose of this study was to evaluate the influence of the presence of major aorto-pulmonary collateral arteries (MAPCAs) on probability of MVOP reconstruction and development of RVOT restenosis in midterm. 49 patients underwent complete repair (either MVOP reconstruction or Rastelli procedure) of PA + VSD in our service. These patients were divided into 2 groups: group 1; 21 patients with MAPCAs, group 2; 28 patients without MAPCAs. There was one operative death (group 1). The probably of MVOP reconstruction was similar between group 1 and group 2 (71 vs 79%, p = 0.57, chi 2 test). Follow-up was completed for 48 survivors with the period ranged 3-108 months (mean 47 months). In group 1, one patient died suddenly at home 10 months after surgery. For 47 long-term patients, the ratio of freedom from RVOT restenosis was 72% (95% CI: 52-92%, Kaplan-Meier method) at 5 year. There was no difference between 2 groups (group 1; 73%, 95% CI: 45-100%, group 2; 74%, 95% CI: 48-99%, respectively, p = 0.85 by Log-Rank test). The presence of MAPCAs in PA + VSD was not a risk factor for either the probably of MVOP reconstruction or development of RVOT restenosis in midterm.

  15. Are new recommendations on the prevention of infective endocarditis applicable in our environment?

    Directory of Open Access Journals (Sweden)

    Ivanović Branislava

    2010-01-01

    Full Text Available Introduction. Over half a century ago the process of prevention of infective endocarditis in patients with predisposed cardiac diseases was started. The application of prevention has been based on the fact that infective endocarditis is preceded by bacteraemia, which can be caused by some invasive diagnostic and therapeutic procedures, and whose development can be prevented by applying antibiotics before an intervention. According to the latest guidelines of the European Society of Cardiology published this year, prevention is recommended only in high risk patients with previous infective endocarditis, prosthetic valves, cyanotic congenital heart diseases without surgical repair or with residual defects, palliative shunts or conduits, congenital heart diseases with complete repair with prosthetic material up to six months after the procedure (surgery or percutaneous intervention, and when the residual defect persists at the site of implantation of a prosthetic material. In addition, antibiotic prophylaxis is limited to dental procedures with the manipulation of gingival or periapical region of the teeth or perforation of the oral mucosa. Objective. The aim of this testing was to confirm whether these novelties in recommendations were applicable in our environment. Methods. Fifty-seven patients (44 men and 13 women with infective endocarditis were included in the testing. Infective endocarditis was diagnosed in 68% of patients based on two major criteria and in 32% based on one major and three minor criteria. Results. In 54.4% of patients the entry site of infection could be determined. Twenty-one percent of patients developed infection after a dental intervention, 17.5% of patients the infection occurred after a skin/soft tissue lesion, whereas urinary infection preceded infective endocarditis in 14% of patients and bowel diverticulosis was a possible cause in of 1.75% of patients. In all cases with infective endocarditis preceded by the dental

    2014-06-01

    An 18-yr-old male hyacinth macaw (Anadorhynchus hyacinthinus) was found dead in his aviary with no preexisting signs. The bird had a chronic history of feather damaging behavior, with severe ulcerative dermatitis. Pathologic findings revealed a vegetative valvular endocarditis, myocarditis, septicemia, chronic severe glomerulonephritis, and thyroid dysplasia. Staphylococcus aureus was isolated from the valve, the liver, and the skin. Repeated trauma and low-rate bacteriemia may have contributed to the development of endocarditis. Translocation of S. aureus skin infection in the bloodstream may lead to subacute endocarditis in humans and such mechanism is suspected in this case. This case suggests that endocarditis associated with S. aureus septicemia is a potential complication of feather damaging behavior. This case also reports a systemic complication of ulcerative dermatitis secondary to feather damaging behavior. Endocarditis has been poorly reported in psittacine species, and such medical complication of feather damaging behavior has never been reported to our knowledge. Furthermore, S. aureus is a bacteria of public health concern and should be integrated into the differential when pet parrots with dermatitis are in proximity to owners.

In this study, we included all patients retrospectively and prospectively diagnosed with Bartonella endocarditis in our French reference center between 2005 and 2013. Our diagnosis was based on the modified Duke criteria and microbiological findings, including serological and PCR results. To review the published literature, we searched all human Bartonella endocarditis cases published in the PubMed database between January 2005 and October 2013. We report here a large series of 106 cases, which include 59 cases that had not previously been reported or mentioned. Indirect immunofluorescence assays, Western blotting, and real-time PCR from total blood, serum, and valve tissue exhibited sensitivities of 58%, 100%, 33%, 36%, and 91%, respectively. The number of cases reported in the literature between 2005 and 2013 increased to reach a cumulative number of 196 cases. The number of cases reported in the literature by other centers is increasing more rapidly than that reported by our French reference center (P Bartonella endocarditis. We suggest that a positive PCR result from a cardiac valve or blood specimen, an IgG titer of ≥800 using an immunofluorescence assay, or a positive Western blot assay be considered major Duke criteria for Bartonella endocarditis. There is no real increase in the incidence of these infections but rather a better understanding and interest in the disease resulting from the improvement of diagnostic tools.

    Transesophageal echocardiography continues to have a central role in the diagnosis of infective endocarditis and its sequelae. Recent technological advances offer the option of 3-dimensional imaging in the evaluation of patients with infective endocarditis. We present an illustrative case and review the literature regarding the potential advantages and limitations of 3-dimensional transesophageal echocardiography in the diagnosis of complicated infective endocarditis. A 51-year-old man, an intravenous drug user who had undergone bioprosthetic aortic valve replacement 5 months earlier, presented with prosthetic valve endocarditis. Preoperative transesophageal echocardiography with 3D rendition revealed a large abscess involving the mitral aortic intervalvular fibrosa, together with a mycotic aneurysm that had ruptured into the left atrium, resulting in a left ventricle-to-left atrium fistula. Three-dimensional transesophageal echocardiography enabled superior preoperative anatomic delineation and surgical planning. We conclude that 3-dimensional transesophageal echocardiography can be a useful adjunct to traditional 2-dimensional transesophageal echocardiography as a tool in the diagnosis of infective endocarditis.

    Full Text Available    Infective endocarditis and periannular abscess formation are serious problems in cardiac valve surgery, requiring extensive surgical debridement and reconstruction of the aortic annulus. We aimed to report two cases which were successfully treated with bioprosthetic valve implantation for infective endocarditis. Transosephageal echocardiography were performed for the diagnosis of one prosthetic and one native destructive aortic valve endocarditis in association with congestive heart failure (NYHA class-VI and abscess formation. Medtronic Freestyle stentless aortic root bioprosthesis was implanted into the left ventricular outflow tract after surgical radical aortic root debridement for each patient followed with medical treatment, which was extended to six weeks. Neither early nor late mortality was detected. One patient required prolonged ventilatory support (two days and permanent DDD-R pacing. Echocardiography showed no signs of valve dysfunction or recurrent endocarditis for both patients in 10 months follow up.Medtronic Freestyle stentless aortic root bioprosthesis may be a good alternative way of treatment to aortic valve and root endocarditis instead of homograft.

    Full Text Available Introduction. Infective endocarditis in the left heart may be complicated by stroke, due to embolisation from infectious valvular vegetations. Infarction of both occipital lobes, which are supplied by the posterior cerebral arteries, is infrequent, and is the cause of cortical blindness from lesion of the visual cortex. Cortical blindness is characterized by intact pupillary reflexes, a normal fundoscopy, and, rarely, denial of visual loss. Case Presentation. We report the case of a 58-year-old woman, recipient of a mechanical aortic valve, who presented with fever, multiple organ dysfunction, and cortical blindness. Transesophageal echocardiography and blood cultures confirmed the diagnosis of infective endocarditis caused by methicillin-sensitive Staphylococcus aureus. Computed tomography of the brain without contrast revealed the presence of infarctions in both occipital lobes. It is noteworthy that the visual loss resolved after treatment of endocarditis. Conclusions. A stroke occurring in a patient presenting with fever and a history of valvular heart disease strongly suggests the presence of infective endocarditis. Bilateral thromboembolic infarcts of the occipital lobes cause cortical blindness, that can resolve after treatment of endocarditis.

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.

    2013-11-01

    Full Text Available Intravenous drug users are at increased risk for developing right-sided infective endocarditis involving the tricuspid and pulmonary valves. Isolated pulmonary valve endocarditis in intravenous drug users is very rare, and these patients often have more complications, such as pulmonary embolism, sepsis, and pneumonia. We report a case with pulmonary valve endocarditis and extensive pulmonary complications, including sepsis, septic emboli, pneumonia, and pneumothorax. Early identification of pulmonic valve endocarditis and treatment with appropriate antibiotics with or without surgical management should provide better outcomes, and clinicians need to think about pulmonary valve endocarditis in patients with complex respiratory presentations.

    An immunological study, with examination for circulating immune complexes (CIC) by precipitation by polyethylene-glycol (PEG) and by fixation of labelled C1q, was carried out in 64 patients with infectious endocarditis (IE). One or more complementary studies during the course of the illness were possible in 23. CIC were found in 84 p. 100 of cases (66 p. 100 of acute IE and 89 p. 100 of subacute IE), during the active phase of the disease. High levels of PEG precipitate were correlated with typical cutaneous signs (including Osler's nodes), with the presence of cryoglobulins. With effective antibiotic treatment, the level of PEG precipitate (17 patients) returned to normal within one month, in parallel with a fall in rheumatoid factor and in cryoglobulins. By contrast, ineffective treatment was invariably reflected (6 patients) by a rise in levels of PEG precipitate. The estimation of CIC using the PEG technique during IE would already appear to be a value aid in cases of difficult diagnosis, and a research area worthy of further exploration within the context of IE.

    Infective endocarditis (IE) of infants is rare, most of which occur associated with congenital heart disease or its cardiac surgery. We experienced a case of sudden death of a four-month-old male infant without congenital heart disease. It was elucidated by postmortem examination that the dead had suffered severe IE, which led him to death. In the microbiological genetic analysis using histological section, the pathogen causing inflammation in the present case was identified as Lactococcus lactis subspecies, although Staphylococci have been reported to be common and important one. Previously reported infectious diseases by Lactococcus lactis subspecies were all adult cases and this is the first report of an infantile death due to Lactococcal IE according to our knowledge. Any fatal disease may be included in sudden death cases targeted for forensic autopsy, even if it is rare. It is expected for forensic pathologists that they note such case and share each experience among themselves and other medical fields to develop a strategy for prevention.

Fundus examination revealed white-centered hemorrhages resembling Roth spots in both macular regions. The spectral-domain optical coherence tomography (SD-OCT showed intraretinal pseudocysts and hyperreflective deposits in the areas corresponding to the Roth spots. Conducted blood tests revealed elevated D-dimer concentration, increased total number of neutrophils, high C-reactive protein concentration, and elevated erythrocyte sedimentation rate. Procalcitonin concentration, platelet count, and body temperature were within normal ranges. A blood culture was ordered and yielded Streptococcus mitis and intravenous antibiotics were started immediately. The patient started complaining of chest and left calf pain. The systemic examination revealed infective endocarditis accompanied by bicuspid aortic valve and paravalvular abscess formation. The patient underwent cardiac surgery with mechanical aortic valve implantation. After recovery, the patient’s visual acuities improved fully.

    Full Text Available Infective endocarditis (IE is a unique diagnostic and therapeutic challenge. It is a severe disease, fatal before penicillin discovery. Atypical presentations frequently led to delayed diagnosis and poor outcome. There was little information about the natural history of the vegetations during medical treatment or the relation of morphologic changes in vegetation to late complications. Application of a new diagnostic criteria and echocardiography, increased the number of definite diagnosis. Trans-thoracic and trans-esophageal echocardiography had an established role in the management of patients with IE. The evolution of vegetation size, its mobility, and consistency, the extent of the disease, and the severity of valvular regurgutation were related to late complications. With therapeutic options including modern antibiotic treatment and early surgical intervention IE turned out to be a curable disease. Reduction in mortality also depended on prevention. Antibiotic prophylaxis of IE was important, but low mortality was also the result of early treatment, especially in the event of early recognition of symptoms and signs of the disease.

He had a left ischiorectal abscess 1 month prior to admission. Physical examination revealed caries on a left upper molar and a well-healed scar on the left buttock, but no heart murmur or evidence of micro-emboli. Blood cultures grew Streptococcus agalactiae. A transesophageal echocardiogram revealed a mobile mass in the right ventricle that attached to chordae tendineae without valvular disease or dysfunction. A computed tomography (CT with contrast revealed the mass within the right ventricle, a left lung cavitary lesion, and a splenic infarction. He was initially treated with penicillin G for a week. Subsequently, ceftriaxone was continued for a total of 8 weeks. A follow-up CT showed no evidence of right ventricular mass 8 weeks after discharge. This is the first reported case of S. agalactiae mural infective endocarditis in a structurally normal heart.

No series of cases from Brazil has been described.Objectives:To describe aspects of S. bovisendocarditis.Methods:This is a case series of patients admitted to a cardiac surgery referral center, during the years 2005-2014. Clinical, laboratory, echochardiographic, colonoscopic, treatment, surgical and outcome variables were studied.Results:Nine patients with S. bovisendocarditis were included; all cases fulfilled the modified Duke criteria. Incidence was 8/220 (4% in years 2006-2014. There were seven male and two female patients; mean age was 56.7 years, standard deviation 13.4. All patients had native aortic valve involvement. Presentation was subacute in 7/9 (71%. Fever was present in 7/9 (77.7%, embolic lesions to solid organs occurred in three, and perivalvular abscess in two patients. All echocardiograms showed moderate to severe valvular regurgitation and vegetations. Microcytic anemia was seen in 7/7 patients. Colonoscopy showed abnormal findings in 7/9 (77.7%. Surgery was indicated for 6/9 patients due to acute aortic regurgitation and left ventricular failure. All patients were discharged home.Conclusions:S. bovismost frequently affected the aortic valve of male patients. Colon disease was frequent. Surgery was indicated frequently due to hemodynamic compromise.

    Full Text Available Nondiphtheria Corynebacterium species are often dismissed as culture contaminants, but they have recently become increasingly recognized as pathologic organisms. We present the case of a 48-year-old male patient on chronic prednisone therapy for rheumatoid arthritis with a history of mitral valve replacement with prosthetic valve. He presented with fever, dizziness, dyspnea on exertion, intermittent chest pain, and palpitations. Transesophageal echocardiography revealed two medium-sized densities along the inner aspect of the sewing ring and one larger density along the atrial surface of the sewing ring consistent with vegetation. Two separate blood cultures grew Corynebacterium propinquum, which were sensitive to ceftriaxone but highly resistant to vancomycin and daptomycin. The patient completed a course of ceftriaxone and repeat TEE study and after 6 weeks demonstrated near complete resolution of the vegetation. To our knowledge, this case represents the first in the literature of Corynebacterium propinquum causing prosthetic valve endocarditis. The ability of these organisms to cause deep-seated systemic infections should be recognized, especially in immune-compromised patients.

    We describe the findings on CT or MRI in five patients with neurological symptoms and underlying infective endocarditis (IE). We noted the size, number, and distribution of lesions, the presence or absence of haemorrhage, and contrast enhancement patterns. The number of lesions ranged from 4 to more than 10 in each patient. Their size varied from punctate to 6 cm; they were distributed throughout the brain. The lesions could be categorized into four patterns based on imaging features. A cortical infarct pattern was seen in all patients. Patchy lesions, which did not enhance, were found in the white matter or basal ganglia in three. Isolated, tiny, nodular or ring-enhancing white matter lesions were seen in three patients, and parenchymal haemorrhages in four. In addition to the occurrence of multiple lesions with various patterns in the same patient, isolated, tiny, enhancing lesions in the white matter seemed to be valuable features which could help to differentiate the neurological complications of IE from other thromboembolic infarcts.

    Identifying the pathogen responsible for culture-negative valve endocarditis often depends on molecular studies performed on surgical specimens. A patient with Ehlers-Danlos syndrome who had an aortic graft, a mechanical aortic valve, and a mitral anulloplasty ring presented with culture-negative prosthetic valve endocarditis and aortic graft infection. Research-based polymerase chain reaction (PCR)/electrospray ionization mass spectrometry on peripheral blood samples identified Bartonella henselae. Quantitative PCR targeting the16S-23S ribonucleic acid intergenic region and Western immunoblotting confirmed this result. This, in turn, permitted early initiation of pathogen-directed therapy and subsequent successful medical management of B henselae prosthetic valve endocarditis and aortic graft infection.

    Libman-Sacks endocarditis is a well-known and rather common cardiac manifestation of systemic lupus erythematosus. Transesophageal and transthoracic echocardiography are the definitive imaging methods used to evaluate cardiac valvular involvement in this disease. Valvular masses (vegetations) and valvular thickening are 2 common morphologic echocardiographic patterns. Libman-Sacks lesions are typically characterized by single-valve involvement and their small size of 1 to 4 mm.Herein, we present the unusual case of a 22-year-old woman with newly diagnosed systemic lupus erythematosus who had large, sterile vegetations of Libman-Sacks endocarditis that involved the mitral and aortic valves. This compromised coronary blood flow and resulted in ventricular fibrillation cardiac arrest. The vegetations were surgically excised, and the patient's cardiac function recovered. We discuss the treatment of the patient and that of Libman-Sacks endocarditis.

    Full Text Available Abstract Background Right-sided endocarditis occurs predominantly in intravenous drug users, patients with pacemakers or central venous lines and with congenital heart diseases. The vast majority of cases involve the tricuspid valve. Case presentation A case of a 31-year-old woman with intravenous drug abuse who had a right-sided vegetation attached to the muscular bundle of the right ventricle is presented. Transthoracic echocardiography revealed a vegetation in the right ventricular outflow tract. Transesophageal echocardiography clearly showed that the 1.8 cm vegetation was not adherent to the pulmonary valve but attached to a muscular bundle. Conclusions Our case points to an unusual location of right-sided endocarditis in intravenous drug users. It confirms that TTE remains an easy and highly sensitive first-line examination for the diagnosis of right-sided endocarditis.

    We report the case of a 55 year-old man presenting with a double aortic and mitral endocarditis for which resected valve culture was repeatedly negative. Specific PCR made on valves because of highly positive blood tests for Bartonella henselae remained negative. A molecular approach was made with 16S rDNA PCR, followed by sequencing. Bartonella quintana was identified as the etiology of endocarditis. B. quintana, "fastidious" bacteria, even if hard to identify in a laboratory, is often reported as a blood culture negative endocarditis (BCNE) agent. Molecular biology methods have strongly improved the diagnosis of BCNE. We propose a review of the literature focusing on the interest of broad-spectrum PCR on valve for the etiological diagnosis of BCNE.

  6. Tricuspid valve endocarditis following central venous cannulation: The increasing problem of catheter related infection

    Full Text Available A central venous catheter (CVC is inserted for measurement of haemodynamic variables, delivery of nutritional supplements and drugs and access for haemodialysis and haemofiltration. Catheterization and maintenance are common practices and there is more to the technique than routine placement as evident when a procedure-related complication occurs. More than 15% of the patients who receive CVC placement have some complications and infectious endocarditis involving the tricuspid valve is a rare and serious complication with high morbidity and mortality. Overenthusiastic and deep insertion of the guide wire and forceful injection through the CVC may lead to injury of the tricuspid valve and predispose to bacterial deposition and endocarditis. We report a case of tricuspid valve endocarditis, probably secondary to injury of the anterior tricuspid leaflet by the guide wire or the CVC that required open heart surgery with vegetectomy and repair of the tricuspid valve.

    Congenital quadricuspid aortic valve is a rare cardiac malformation with an unknown risk of infective endocarditis. We report a case of quadricuspid aortic valve complicated with infective endocarditis. A 53-year-old Japanese woman was hospitalized with leg edema and a fever of unknown origin. Corynebacterium striatum was detected in the blood culture. Echocardiography demonstrated a quadricuspid aortic valve with vegetation and severe functional regurgitation. The condition was diagnosed as a quadricuspid aortic valve with infective endocarditis, for which surgery was performed. The quadricuspid aortic valve had three equal-sized cusps and one smaller cusp (type B according to Hurwitz classification). We dissected the vegetation and infectious focus and implanted a mechanical valve. Following the case report, we review the literature.

    2010-01-01

    Endocarditis lesions from 117 slaughter pigs were examined pathologically and etiologically in addition to 90 control hearts with cardiac valves. Lesions were located on the valves; however, the lesions had extended to the walls in 21 cases (18%). Lesions predominated on the mitral valve (59...... 10 cases of endocarditis due to S. suis and E. rhusiopathiae were disclosed. Within lesions, streptococci predominated (53%) followed by E. rhusiopathiae (30%). Distinct features of both the lesions and the shape and localization of bacterial colonies were related to streptococci and E. rhusiopathiae....... The propensity for streptococci to be localized on more than 1 valve in single hearts may be because S. suis-infected pigs tend to have been infected for a longer period compared with E. rhusiopathiae. Mineralization of endocarditis lesions was significantly associated with infection by streptococci...

    Candida infective endocarditis is a rare disease with a high mortality rate. Our understanding of this infection is derived from case series, case reports, and small prospective cohorts. The purpose of this study was to evaluate the clinical features and use of different antifungal treatment regimens for Candida infective endocarditis. This prospective cohort study was based on 70 cases of Candida infective endocarditis from the International Collaboration on Endocarditis (ICE)-Prospective Cohort Study and ICE-Plus databases collected between 2000 and 2010. The majority of infections were acquired nosocomially (67%). Congestive heart failure (24%), prosthetic heart valve (46%), and previous infective endocarditis (26%) were common comorbidities. Overall mortality was high, with 36% mortality in the hospital and 59% at 1 year. On univariate analysis, older age, heart failure at baseline, persistent candidemia, nosocomial acquisition, heart failure as a complication, and intracardiac abscess were associated with higher mortality. Mortality was not affected by use of surgical therapy or choice of antifungal agent. A subgroup analysis was performed on 33 patients for whom specific antifungal therapy information was available. In this subgroup, 11 patients received amphotericin B-based therapy and 14 received echinocandin-based therapy. Despite a higher percentage of older patients and nosocomial infection in the echinocandin group, mortality rates were similar between the two groups. In conclusion, Candida infective endocarditis is associated with a high mortality rate that was not impacted by choice of antifungal therapy or by adjunctive surgical intervention. Additionally, echinocandin therapy was as effective as amphotericin B-based therapy in the small subgroup analysis.

    Mitral valve leaflet aneurysm is a rare and potentially devastating complication of aortic valve endocarditis. We report the case of a 48-year-old man who had endocarditis of the native aortic valve and a concomitant aneurysm of the anterior mitral valve leaflet. Severe mitral regurgitation occurred after the aneurysm perforated. The patient showed no signs of heart failure and completed a 6-week regimen of antibiotic therapy before undergoing successful aortic and mitral valve replacement. In addition to the patient's case, we review the relevant medical literature.

We present a 52-year-old woman with a history of aortic valve replacement and rheumatoid arthritis treated with Etanercept with chronic Q fever manifesting as prosthetic valve infective endocarditis. Explanted valve tissue showed organisms confirmed to be C. burnetii by PCR (polymerase chain reaction sequencing. She subsequently reported consumption of unpasteurized cow milk which was the likely source of C. burnetii. She continues to do well 6 months after valve replacement on oral doxycycline and hydroxychloroquine.

    Bacterial endocarditis following atrial septal defect closure using Amplatzer device in a child is extremely rare. We report a 10-year-old girl who developed late bacterial endocarditis, 6 years after placement of an Amplatzer atrial septal occluder device. Successful explantation of the device and repair of the resultant septal defect was carried out using a homograft patch. The rare occurrence of this entity prompted us to highlight the importance of a closed long-term follow up, review the management and explore preventive strategies for similar patients who have multiple co-morbidities and a cardiac device. A high index of suspicion is warranted particularly in pediatric patients.

    @@ Qfever is a worldwide zoonosis and its agent is Coxiella burnetii (C. burnetii).1 There are two forms of Q fever: acute and chronic. Acute Q fever is caused by primary infection with C. burnetii and its main clinical features are high fever, granulomatous hepatitis and atypical pneumonia.2,3 Acute Q fever is extremely prone to develop chronic infection if it is improperly treated. Endocarditis is the main characteristic of chronic Q fever and it accounts for 3% to 5% of all cases of endocarditis.4,5

    Infective endocarditis (IE) remains a serious disease. Aorta-to-right atrium fistula is a rare but very serious compli-cation of IE and predicts a higher mortality. This report describes a 50-year-old man with endocarditis, vegetation, perforation of noncoronary sinus, and formation of two aorta-to-right atrium fistulas with native valves detected by transthoracic echocardi-ography. This disease is lethal despite developments in cardiac imaging and antibacterial therapy. Early diagnosis, aggressive antibacterial therapy, and surgical treatment may improve the prognosis.

    Left atrial wall dissection is a rare condition; most cases are iatrogenic after mitral valve surgery. A few have been reported as sequelae of blunt chest trauma, acute myocardial infarction, and invasive cardiac procedures. On occasion, infective endocarditis causes left atrial wall dissection. We report a highly unusual case in which a 41-year-old man presented with native mitral valve infective endocarditis that had caused left atrial free-wall dissection. Although our patient died within an hour of presentation, we obtained what we consider to be a definitive diagnosis of a rare sequela, documented by transthoracic and transesophageal echocardiography.

    2016-02-01

    This report describes one the first cases of antiphospholipid syndrome and Libman-Sacks endocarditis in a bioprosthetic valve. A redo mitral valve replacement was carried out owing to early deterioration of the prior valve. Initially it was considered secondary to rheumatic heart disease; however, pathology analysis and autoimmune workup revealed antiphospholipid syndrome with Libman-Sacks endocarditis. We believe certain populations with mitral valve stenosis may have an underlying antiphospholipid syndrome. As a result, there needs to be a lower threshold for identifying this disease.

    Coagulase-negative staphylococci (CNS) are important causes of infective endocarditis (IE), but their microbiological profiles are poorly described. We performed DNA target sequencing and susceptibility testing for 91 patients with definite CNS IE who were identified from the International Collaboration on Endocarditis—Microbiology, a large, multicenter, multinational consortium. A hierarchy of gene sequences demonstrated great genetic diversity within CNS from patients with definite endocarditis that represented diverse geographic regions. In particular, rpoB sequence data demonstrated unique genetic signatures with the potential to serve as an important tool for global surveillance. PMID:18367572

    Infective endocarditis during pregnancy carries a high mortality risk, both for the mother and for the foetus and requires a multidisciplinary team in the management of complicated cases. We report our experience with a 39-year old patient, affected by an acute active mitral endocarditis due to Abiotrophia defectiva at the 14th gestational week, strongly motivated to continue the pregnancy. Our patient successfully underwent mitral valve replacement with a normothermic high-flow cardiopulmonary bypass under continuous intraoperative foetal monitoring. Caesarean section occurred at the 38th gestational week. The delivery was uneventful and both the mother and child are doing well at the 16-month follow-up.

    A relationship between infective endocarditis and colon cancer was established in 1950, and Streptococcus bovis was successfully isolated in 1970. However, this association and its pathogenesis still remain unclear. In this paper, we describe the clinical case of a patient with a history of colon cancer and infective endocarditis caused by Streptococcus bovis. The role of S bovis as an aetiological agent in the development of colon cancer is intriguing but uncertain. S bovis infection should be considered a silent sign of gastrointestinal malignancy or hepatic disease. We believe that in order to demonstrate the presence of colon cancer, all patients with S bovis infection require an endoscopic investigation of the colon.

    This review was undertaken to determine the role of surgery in the treatment of brucella endocarditis. All English and French articles reporting brucella endocarditis (1966–2011) in Pubmed, Google and Scopus were reviewed. 308 cases were identified and Linear and Logistic regression was performed. Surgery improved outcomes by decreasing mortality from 32.7% in the medical treatment only group to 6.7% in the combined surgical and medical treatment group (p<.001). This association was still significant while controlling for other contributing factors. In the absence of a controlled trial, we recommend the utmost vigilance and consideration of surgical management in treating such patients. PMID:23102495

    Libman-Sacks endocarditis, first discovered in 1924, is a cardiac manifestation of systemic lupus erythematosus (SLE). Valvular involvement has been associated with SLE and antiphospholipid syndrome (APS). Mitral valve, especially its posterior leaflet, is most commonly involved. We report a case of a 34 year old woman with antiphospholipid antibody syndrome and SLE, who presented with mitral valve regurgitation. The patient underwent a prosthetic mitral valve replacement, with no followup complications. We suggest mechanical valve replacement employment in the management of mitral regurgitation in Libman-Sacks endocarditis, in view of the recent medical literature and our own case report.

    Decision making regarding surgery for acute bacterial endocarditis is complex given its heterogeneity and often fatal course. Few studies have investigated the utility of operative risk scores in this setting. Endocarditis-specific scores have recently been developed. We assessed the prognostic utility of contemporary risk scores for mortality and morbidity after endocarditis surgery. Additive and logistic EuroSCORE I, EuroSCORE II, additive Society of Thoracic Surgeon's (STS) Endocarditis Score and additive De Feo-Cotrufo Score were retrospectively calculated for patients undergoing surgery for endocarditis during 2005-2011. Pre-specified primary outcomes were operative mortality, composite morbidity and mortality during follow-up. A total of 146 patients were included with an operative mortality of 6.8 % followed for 4.1 ± 2.4 years. Mean scores were additive EuroSCORE I: 8.0 ± 2.5, logistic EuroSCORE I: 13.2 ± 10.1 %, EuroSCORE II: 9.1 % ± 9.4 %, STS Score: 32.2 ± 13.5 and De Feo-Cotrufo Score: 14.6 ± 9.2. Corresponding areas under curve (AUC) for operative mortality 0.653, 0.645, 0.656, 0.699 and 0.744; for composite morbidity were 0.623, 0.625, 0.720, 0.714 and 0.774; and long-term mortality 0.588, 0.579, 0.686, 0.735 and 0.751. The best tool for post-operative stroke was EuroSCORE II: AUC 0.837; for ventilation >24 h and return to theatre the De Feo-Cotrufo Scores were: AUC 0.821 and 0.712. Pre-operative inotrope or intra-aortic balloon pump treatment, previous coronary bypass grafting and dialysis were independent predictors of operative and long-term mortality. In conclusion, risk models developed specifically from endocarditis surgeries and incorporating endocarditis variables have improved prognostic ability of outcomes, and can play an important role in the decision making towards surgery for endocarditis.

    Although infective endocarditis (IE) is relatively uncommon, it remains an important clinical entity with a high in-hospital and 1-year mortality. It is most commonly caused by viridans streptococci. Staphylococcus aureus is responsible for a malignant course of IE and often requires early surgery to eradicate. Other rarer causes are various bacilli, including the HACEK (Haemophilus, Actinobacillus,Cardiobacterium, Eikenella and Kingella spp.) group of organisms and fungi. The clinical presentation varies. Patients may present with a nonspecific illness, valve dysfunction, heart failure (HF) and symptoms due to peripheral embolisation. The diagnosis is traditionally based on the modified Duke criteria and rests mainly on clinical features and to a lesser extent on certain laboratory findings,microbiological assessment and cardiovascular imaging. Identification of the offending micro-organism is not only important from a diagnostic point of view, but also makes targeted antibiotic treatment possible and provides useful prognostic information. A significant proportion of microbiological cultures are negative, frequently owing to the administration of antibiotics prior to appropriate culture.Blood-culture-negative IE poses significant diagnostic and treatment challenges. The course of the disease is frequently complicated, and sequelae include HF, local intracardiac extension of infection (abscess, fistula, pseudoaneurysm), stroke and intracranial haemorrhage due to septic emboli or mycotic aneurysm formation as well as renal injury. Management includes prolonged intravenous antibiotics and consideration for early surgery with removal of infective tissue and valve replacement in patients who have poor prognostic features or complications. Antibiotic administration for at-risk patients to prevent bacteraemia during specific procedures (particularly dental) is recommended to prevent IE. The patient population who would benefit from antibiotic prophylaxis has become

    Infective endocarditis (IE) is a serious disease that is associated with dental diseases and treatment. The objective of this study was to summarize the epidemiological information about IE and reevaluate previous causal models in light of this evidence. The world biomedical literature was searched from 1930 to 1996 for descriptive and analytic epidemiological studies of IE. Multiple searching strategies were performed on 9 databases, including MEDLINE, CATLINE, and WORLDCAT. Results show that: 1) the incidence of IE varies between 0.70 to 6.8 per 100,000 person-years: 2) the incidence of IE increases 20 fold with advancing age: 3) over 50% of all IE cases are not associated with either an obvious procedural or infectious event 3 months prior to developing symptoms; 4) about 8% of all IE cases are associated with periodontal or dental disease without a dental procedure: 5) the time from the diagnosis of heart valve deformities to the development of IE approaches 20 years: 6) the median time from identifiable procedures to the onset of IE symptoms is about 2 to 4 weeks: 7) the risk of IE after a dental procedure is probably in the range of 1 per 3,000 to 5,000 procedures: and 8) over 80% of all IE cases are acquired in the community, and the bacteria are part of the host's endogenous flora. The synthesis of these data demonstrates that IE is a disorder with the epidemiological picture of a chronic disease such as cancer, instead of an acute infectious disease, with a long latent period and possibly several definable intermediates or stages. A new causal model is proposed that includes early bacteremias that may "prime" the endothelial surface of the heart valves over many years, and a late bacteremia over days to weeks that allows adherence and colonization of the valve, resulting in the characteristic fulminant infection.

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.

    Traditionally, tricuspid valve endocarditis is uncommon in the Middle East region. However, recent global data indicate growing trends in the use of illicit drug abuse, specifically injectable heroin, in the Middle East Gulf region. The presence of many transit port services in the Middle East Gulf States has led to smuggling of substance abuse drugs in the region. The Middle East Gulf States, currently a transit market, are also becoming a growing consumer market in view of the increased substance abuse in the youth. However, there is a paucity of data with respect to the prevalence or incidence of tricuspid valve endocarditis in the region, probably due to underdiagnosis or underreporting. A high index of suspicion of tricuspid valve endocarditis is essential in patients with a history of intravenous drug abuse. This article reviews the epidemiology of illicit drug abuse in the Middle East Gulf region, as well as the diagnosis and treatment of tricuspid valve endocarditis, and calls for all physicians in the region to be vigilant while dealing with intravenous drug abuse.

    Infective endocarditis is a life-threatining infectious disease characterized by high morbidity and mortality. Leukocytes play a main role in infectious diseases. Neutrophils and lymphocytes are subgroup of leukocytes, and they are routinely measured as a part of automated complete blood count test. The neutrophil-to-lymphocyte ratio is an independent predictor of unfavorable clinical outcomes in infectious and cardiovascular diseases.

    The association of positive cytoplasmic antineutrophil antibody (ANCA) necrotizing crescentic glomerulonephritis with endocarditis raises diagnostic issues. Indeed, it is often difficult to determine if the kidney injury is either secondary to an infectious disease or caused by an ANCA-associated small vessel vasculitis. We report a 59-year-old man admitted in nephrology for acute glomerular syndrome in whom the renal biopsy showed a crescentic necrotizing glomerulonephritis. A diagnosis of vasculitis was initially considered in the presence of high titer of ANCA (anti-proteinase 3). Because of associated Staphyloccocus aureus endocarditis the patient received both corticosteroids and antibiotics that allowed remission of both kidney injury and endocarditis. The renal presentation and the disappearance of ANCA support the infectious etiology of this glomerulonephritis rather than an ANCA-associated small vessel vasculitis. It is important to be cautious in the presence of ANCA positive extracapillary glomerulonephritis and endocarditis should be ruled out before initiation of corticosteroids that may be nevertheless necessary in severe acute glomerulonephritis.

    2008-03-01

    Full Text Available We report a fourth case of prosthetic valve endocarditis caused by the newly described micrococcal species: Kytococcus schroeteri. A 38-year old male was admitted to our hospital with suspected prosthetic valve endocarditis. In three blood cultures and in the prosthetic heart valve culture grew the same type of microrganism, initially identified as Micrococcus luteus. Presuntive assignment to the genus Kytococcus was suggested by the arginina dihydrolase activity and by the resistence to penicillin, oxacillin and methicillin, characteristics which are not shared by other micrococci. Further biochemical tests confirmed that the isolates belonged to the genus Kytococcus (negative reaction for oxydase, esculin and urease, positive for catalase and arginine dihydrolase species schroeteri (alpha-glucosidase positive. The patient was treated with vancomycin, gentamicin and rifampicin. After the valve replacement, on the 20th day of hospitalization, the patient’s biological parameters returned to normal values, and after one mounth the resolution of the disease was completed. The diagnosis of four cases by K. schroeteri endocarditis, described within a short period of time (2003-2006, might indicate a specific pathogenicity of this new species. In case of endocarditis diagnosis, the suspect of the genus Kytococcus involvement should be considered each time the aerobic Gram positive cocci, with arginina dihidrolase activiy and the resistence to penicillin, oxacillin and methicillin, are isolated by significative biological samples.

    2014-12-01

    A dog evaluated for acute onset of neurologic clinical signs was discovered to have a porcupine quill traversing the left atrium with fungal endocarditis. The dog had been quilled by a porcupine one month prior to presentation and had had several quills removed from the thoracic inlet and left dorsal shoulder areas. A new murmur was identified during the initial examination. Echocardiographic changes consistent with mitral valve endocarditis were identified, in addition to a linear, hyperechoic structure in the left atrium. A thoracic CT identified a possible mediastinal migrating foreign body tract. The foreign body was surgically removed and confirmed as a porcupine quill. Routine aerobic cultures of blood and pericardial samples resulted in growth of presumptive candidal organisms. PCR amplification and sequencing of samples from pericardial cultures identified the presence of a fungal organism, Lodderomyces elongisporus. The neurologic signs were attributed to a left-sided central vestibular lesion presumed secondary to an embolic event from infective endocarditis. After 3 months of antimicrobial and antifungal therapy the valvular changes had markedly improved and the clinical signs resolved. To the authors' knowledge, this is the first description of fungal endocarditis secondary to an intracardiac foreign body in a dog.

    Infective endocarditis is a disease normally of bacterial cause which affects the endocardic tissue, specifically the valves (native or prosthetic). It is a serious illness and mortality rates remain high, ranging between 20% and 40%. Previous reports have evidenced the potential role of cytokines in the diagnosis of this disease, but no information is available on their relationship with outcome. We recruited 26 consecutive patients with late prosthetic valve endocarditis requiring surgical treatment according to Duke criteria. Eight cytokines were measured in plasma in the first 24 h following diagnosis by using a Bio-Rad multiplex assay. Levels of IL-6, IL-8 and interferon gamma (IFN-γ) were higher in non survivors. Receiver operating characteristic curve analysis evidenced that IL-6, IL-8 and IFN-γ behaved as good diagnostic tests for identifying those patients with fatal outcome (area under the curve, CI 95%, p): IL-6: [0.81 (0.61-1.00) 0.012]; IL-8 [0.76 (0.56-0.96) 0.035]; IFN-γ [0.79 (0.59-0.99) 0.021]. Levels of IL-6, IL-8 and IFN-γ correlated positively between them, indicating that they are produced as consequence of a simultaneous response to the infection. Our findings support the participation of IL-6, IL-8 and IFN-γ in the events linked to fatal outcome in infective prosthetic valve endocarditis.

    Tricuspid infective endocarditis is rare and represents five to 10% of all cases of infective endocarditis. It occurs predominantly in intravenous drug users, and patients with central venous catheters or intracardiac probes. We report on the case of subacute tricuspid infective endocarditis in a girl of 17 years. She had no particular cardiovascular history. She was admitted for a persistent fever with cachexy, cough and thoracic pains, and right heart failure that appeared one month after a clandestine abortion. Transthoracic echocardiography found several vegetations on the tricuspid valve with massive tricuspid regurgitation. The chest X-ray showed bilateral excavated lung abscesses and condensation areas. Blood culture was not done and broad-spectrum antibiotic therapy was given. She was apyretic after 10 days. However, the massive tricuspid regurgitation with right heart failure persisted. She was discharged from hospital after 40 days of treatment. Although rare, infective endocarditis is one of the more serious complications of gynaecological procedures, particularly clandestine abortion. Therefore any young girl with persistent fever must be suspected of clandestine abortion.

  6. Infective endocarditis in the U.S., 1998-2009: a nationwide study.

    Directory of Open Access Journals (Sweden)

    David H Bor

    Full Text Available BACKGROUND: Previous studies based on local case series estimated the annual incidence of endocarditis in the U.S. at about 4 per 100,000 population. Small-scale studies elsewhere have reported similar incidence rates. However, no nationally-representative population-based studies have verified these estimates. METHODS AND FINDINGS: Using the 1998-2009 Nationwide Inpatient Sample, which provides diagnoses from about 8 million U.S. hospitalizations annually, we examined endocarditis hospitalizations, bacteriology, co-morbidities, outcomes and costs. Hospital admissions for endocarditis rose from 25,511 in 1998 to 38, 976 in 2009 (12.7 per 100,000 population in 2009. The age-adjusted endocarditis admission rate increased 2.4% annually. The proportion of patients with intra-cardiac devices rose from 13.3% to 18.9%, while the share with drug use and/or HIV fell. Mortality remained stable at about 14.5%, as did cardiac valve replacement (9.6%. Other serious complications increased; 13.3% of patients in 2009 suffered a stroke or CNS infection, and 5.5% suffered myocardial infarction. Amongst cases with identified pathogens, Staphylococcus aureus was the most common, increasing from 37.6% in 1998 to 49.3% in 2009, 53.3% of which were MRSA. Streptococci were mentioned in 24.7% of cases, gram-negatives in 5.6% and Candida species in 1.0%. We detected no inflection in hospitalization rates after changes in prophylaxis recommendations in 2007. Mean age rose from 58.6 to 60.8 years; elderly patients suffered higher rates of myocardial infarction and death, but slightly lower rates of Staphylococcus aureus infections and neurologic complications. Our study relied on clinically diagnosed cases of endocarditis that may not meet strict criteria. Moreover, since some patients are discharged and readmitted during a single episode of endocarditis, our hospitalization figures probably slightly overstate the true incidence of this illness. CONCLUSIONS: Endocarditis

    AimTo evaluate the feasibility of image fusion (IF) of pre-procedural arterial-phase CT angiography or MR angiography with intra-procedural fluoroscopy for road-mapping in endovascular treatment of aorto-iliac steno-occlusive disease.Materials and MethodsBetween September and November, 2014, we prospectively evaluated 5 patients with chronic aorto-iliac steno-occlusive disease, who underwent endovascular treatment in the angiography suite. Fusion image road-mapping was performed using angiographic phase CT images or MR images acquired before and intra-procedural unenhanced cone-beam CT. Radiation dose of the procedure, volume of intra-procedural iodinated contrast medium, fluoroscopy time, and overall procedural time were recorded. Reasons for potential fusion imaging inaccuracies were also evaluated.ResultsImage co-registration and fusion guidance were feasible in all procedures. Mean radiation dose of the procedure was 60.21 Gycm2 (range 55.02–63.75 Gycm2). The mean total procedure time was 32.2 min (range 27–38 min). The mean fluoroscopy time was 12 min and 3 s. The mean procedural iodinated contrast material dose was 24 mL (range 20–40 mL).ConclusionsIF gives Interventional Radiologists the opportunity to use new technologies in order to improve outcomes with a significant reduction of contrast media administration.

    Full Text Available We report a case of a 72-year-old patient considered unfit for open surgery, presenting with paraanastomotic aneurysms of all three anastomoses, 13 years after an open aortobiiliac reconstruction for abdominal aortic aneurysm. This patient was successfully treated with an endovascular approach using a left aortouniiliac endograft and a right iliac tubular endograft, followed by crossover femorofemoral bypass. This report illustrates the usefulness of a minimally invasive approach for solving this complication of aortic open surgery and discusses technical issues related to endovascular devices in this particular setting.Relatamos um caso de um paciente de 72 anos não considerado elegível para cirurgia aberta, apresentando aneurismas para-anastomóticos das três anastomoses, 13 anos após uma reconstrução aberta aorto-biilíaca para aneurisma aórtico abdominal. Este paciente foi tratado com sucesso através de abordagem endovascular usando uma endoprótese aorto-uniilíaca esquerda e uma endoprótese tubular ilíaca direita, seguida por derivação cruzada fêmoro-femoral. Este relato ilustra a utilidade de uma abordagem minimamente invasiva para o tratamento desta complicação da cirurgia aórtica aberta e discute questões técnicas relacionadas a dispositivos endovasculares neste contexto em especial.

    Although infection by Corynebacterium diphtheriae is a model of extracellular mucosal pathogenesis, different clones have been also associated with invasive infections such as sepsis, endocarditis, septic arthritis and osteomyelitis. The mechanisms that promote C. diphtheriae infection and haematogenic dissemination need further investigation. In this study we evaluated the association and invasion mechanisms with human umbilical vein endothelial cells (HUVECs) and experimental arthritis in mice of endocarditis-associated strains and control non-invasive strains. C. diphtheriae strains were able to adhere to and invade HUVECs at different levels. The endocarditis-associated strains displayed an aggregative adherence pattern and a higher number of internalized viable cells in HUVECs. Transmission electron microscopy (TEM) analysis revealed intracellular bacteria free in the cytoplasm and/or contained in a host-membrane-confined compartment as single micro-organisms. Data showed bacterial internalization dependent on microfilament and microtubule stability and involvement of protein phosphorylation in the HUVEC signalling pathway. A high number of affected joints and high arthritis index in addition to the histopathological features indicated a strain-dependent ability of C. diphtheriae to cause severe polyarthritis. A correlation between the arthritis index and increased systemic levels of IL-6 and TNF-α was observed for endocarditis-associated strains. In conclusion, higher incidence of potential mechanisms by which C. diphtheriae may access the bloodstream through the endothelial barrier and stimulate the production of pro-inflammatory cytokines such as IL-6 and TNF-α, in addition to the ability to affect the joints and induce arthritis through haematogenic spread are thought to be related to the pathogenesis of endocarditis-associated strains.

    Background: The pathophysiology of infective endocarditis involves a pathogen/host tissue interaction, leading to formation of infected thrombotic vegetations. Annexin V is a ligand of phosphatidyl-serines exposed by activated platelets and apoptotic cells. Because vegetations are platelet-fibrin clots in which platelet pro-aggregant activity is enhanced by bacterial colonization, we investigated the ability of annexin V labeled with technetium {sup 99m}Tc ({sup 99m}Tc-ANX) to provide functional imaging of these vegetations in experimental models of infective endocarditis. This ability was assessed in rabbits and rats because of the different interest of these 2 species in preclinical analysis. Methods and Results: Non-bacterial thrombotic endocarditis was induced with the use of a catheter left indwelling through the aortic or tricuspid valve, and animals were injected with either a bacterial inoculum or saline. Scintigraphic investigations were performed 5 days later and showed a higher {sup 99m}Tc-ANX uptake by vegetations in infected versus non-infected animals (ratio,1.3 for in vivo acquisitions and 2 for autoradiography; P {<=} 0.0001 for all), whereas no significant uptake was present in controls. Right-sided endocarditis was associated with pulmonary uptake foci corresponding to emboli. Histological analysis of vegetations showed a specific uptake of {sup 99m}Tc-ANX at the interface between circulating blood and vegetation. In parallel, underlying myocardial tissue showed myocyte apoptosis and mucoid degeneration, without extracellular matrix degradation at this stage. Conclusions: {sup 99m}Tc-ANX is suitable for functional imaging of platelet-fibrin vegetations in endocarditis, as well as embolic events. {sup 99m}Tc-ANX uptake reflects mainly platelet activation in the luminal layer of vegetations. This uptake is enhanced by bacterial colonization. (authors)

    Enterococcus faecium is a multidrug-resistant opportunist causing difficult-to-treat nosocomial infections, including endocarditis, but there are no reports experimentally demonstrating E. faecium virulence determinants. Our previous studies showed that some clinical E. faecium isolates produce a cell wall-anchored collagen adhesin, Acm, and that an isogenic acm deletion mutant of the endocarditis-derived strain TX0082 lost collagen adherence. In this study, we show with a rat endocarditis model that TX0082 Deltaacm::cat is highly attenuated versus wild-type TX0082, both in established (72 h) vegetations (P Acm the first factor shown to be important for E. faecium pathogenesis. In contrast, no mortality differences were observed in a mouse peritonitis model. While 5 of 17 endocarditis isolates were Acm nonproducers and failed to adhere to collagen in vitro, all had an intact, highly conserved acm locus. Highly reduced acm mRNA levels (>or=50-fold reduction relative to an Acm producer) were found in three of these five nonadherent isolates, including the sequenced strain TX0016, by quantitative reverse transcription-PCR, indicating that acm transcription is downregulated in vitro in these isolates. However, examination of TX0016 cells obtained directly from infected rat vegetations by flow cytometry showed that Acm was present on 40% of cells grown during infection. Finally, we demonstrated a significant reduction in E. faecium collagen adherence by affinity-purified anti-Acm antibodies from E. faecium endocarditis patient sera, suggesting that Acm may be a potential immunotarget for strategies to control this emerging pathogen.

    From an epidemiologic point of view, right-sided infective endocarditis (RSIE) affects different types of patients: intravenous drug users (IDUs), cardiac device carriers (pacemakers and implantable automatic defibrillators), and the "3 noes" endocarditis group: no left-sided, no IDUs, no cardiac devices. Our objective is to describe and compare the clinical profile and outcome of these groups of patients. Every episode of infective endocarditis (IE) consecutively diagnosed in 3 tertiary centers from 1996 to 2012 was included in an ongoing multipurpose database. We assessed 85 epidemiologic, clinical, echocardiographic, and outcome variables in patients with isolated RSIE. A bivariated comparative analysis between the 3 groups was conducted.Among 866 IE episodes, 121 were classified as isolated RSIE (14%): 36 IDUs (30%), 65 cardiac device carriers (54%), and 20 "3 noes" group (16%). IDUs were mainly young men (36 ± 7 years) without previous heart disease, few comorbidities, and frequent previous endocarditis episodes (28%). Human immunodeficiency virus infection was frequent (69%). Cardiac device carriers were older (66 ± 15 years) and had less comorbidities (34%). Removal of the infected device was performed in 91% of the patients without any death. The "3 noes" endocarditis group was composed mainly by middle-age men (56 ± 18 years), health care related infections (50%), and had many comorbidities (75%). Whereas Staphylococcus aureus were the most frequent cause in IDUs (72% vs 34% in device carriers and 34% in the "3 noes" group, P = 0.001), coagulase negative Staphylococci predominated in the device carriers (58% vs 11% in drug users and 35% in the "3 noes", P < 0.001). Significant differences in mortality were found (17% in drug users, 3% in device carriers, and 30% in the "3 noes" group; P < 0.001). These results suggest that RSIE should be separated into 3 groups (IDUs, cardiac device carriers, and the "3 noes") and considered as independent entities as

    Infective endocarditis and hepatosplenic abscesses are rare manifestations of cat scratch disease (CSD), especially among immunocompetent adults. An otherwise healthy woman who presented with fever and abdominal pain was diagnosed with multiple abscesses in the spleen and the liver, as well as a mitral valve vegetation. PCR on spleen tissue was positive for Bartonella henselae. Prolonged treatment with doxycycline and gentamicin led to complete recovery. Review of the literature revealed 18 cases of hepatosplenic CSD in immunocompetent adults; the majority presented with fever of unknown origin and abdominal pain. In most cases the causative organism was B. henselae and the pathological findings were necrotizing granulomas, similar to the pathological features in classic CSD. Concomitant endocarditis was diagnosed in one case. Because Bartonella is one of the leading pathogens of culture-negative endocarditis, we raise the question of whether a comprehensive evaluation for endocarditis is needed in cases of systemic CSD.

    Use of cardiovascular implantable electronic devices (CIED), including permanent pacemakers (PPM) and implantable cardioverter defibrillators (ICD), has increased dramatically over the past two decades. Most CIED infections are caused by staphylococci. Fungal causes are rare and their prognosis is poor. To our knowledge, there has not been a previously reported case of multifocal Candida endocarditis involving both a native left-sided heart valve and a CIED lead. Here, we report the case of a 70-year-old patient who presented with nausea, vomiting, and generalised fatigue, and was found to have Candida glabrata endocarditis involving both a native aortic valve and right atrial ICD lead. We review the literature and summarise four additional cases of CIED-associated Candida endocarditis published from 2009 to 2014, updating a previously published review of cases prior to 2009. We additionally review treatment guidelines and discuss management of CIED-associated Candida endocarditis.
