    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.

    Asymptomatic rupture of a sinus of Valsalva aneurysm is rare. A fistula following rupture of a sinus of Valsalva aneurysm may cause infective endocarditis. Here, we report a case of infective endocarditis of an aorto-right atrial fistula caused by asymptomatic rupture of a sinus of Valsalva aneurysm. A 45-year-old male, who was first diagnosed with a heart murmur at the age of 37 years, presented with fever. Blood culture was positive for Streptococcus gordonii. Ultrasound echocardiography revealed an aorto-right atrial fistula caused by rupture of a sinus of Valsalva aneurysm. After the infective endocarditis was healed by antibiotics, we successfully performed surgical repair of the aorto-right atrial fistula. Although asymptomatic rupture of a sinus of Valsalva aneurysm is uncommon, it should be recognized as a possible cause of infective endocarditis. PMID:27180251

    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.

    Infective endocarditis is a serious disease of the endocardium of the heart and cardiac valves, caused by a variety of infectious agents, ranging from streptococci to rickettsia. The proportion of cases associated with rheumatic valvulopathy and dental surgery has decreased in recent years, while endocarditis associated with intravenous drug abuse, prosthetic valves, degenerative valve disease, implanted cardiac devices, and iatrogenic or nosocomial infections has emerged. Endocarditis causes constitutional, cardiac and multiorgan symptoms and signs. The central nervous system can be affected in the form of meningitis, cerebritis, encephalopathy, seizures, brain abscess, ischemic embolic stroke, mycotic aneurysm, and subarachnoid or intracerebral hemorrhage. Stroke in endocarditis is an ominous prognostic sign. Treatment of endocarditis includes prolonged appropriate antimicrobial therapy and in selected cases, cardiac surgery. In ischemic stroke associated with infective endocarditis there is no indication to start antithrombotic drugs. In previously anticoagulated patients with an ischemic stroke, oral anticoagulants should be replaced by unfractionated heparin, while in intracranial hemorrhage, all anticoagulation should be interrupted. The majority of unruptured mycotic aneurysms can be treated by antibiotics, but for ruptured aneurysms, endovascular or neurosurgical therapy is indicated. PMID:24365290

    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.

    Despite the progress in medicine, infectious endocarditis is often diagnosed late, as its symptomatology is subject to a high variability. The clinical features are usually atypical. Since the introduction of the Duke criteria, clinical, bacteriological and echocardiographical findings are being integrated, allowing an earlier definitive diagnosis. The incidence remains practically stable. The decrease in post-rheumatic valvular heart disease at population level is compensated by an increase in degenerative valvular heart disease as predisposing factor. Moreover, the share of patients with intravascular foreign material is increasing. Endocarditis is usually characterized by a complicated development. About half of the patients develop heart failure as a consequence of the destruction of the affected valve with serious valvular insufficiency. One third of the patients present cerebral or peripheral embolization. Embolization predominantly occurs at the beginning, until the first two weeks of antibiotic treatment. Abscess formation occurs more frequently than is suspected based on echographical examinations. Particularly a Staphylococcus aureus infection in the presence of an artificial valve leads to extravalvular extension with abscess formation around the artificial valve. Treatment should be initiated promptly. High doses of antibiotics, tailored to the microorganism and the valve type (native or artificial valve), are administered intravenously during four, or more frequently, six weeks. In more than half of the patients cardiac surgery is also required. As soon as an indication for cardiac surgery is present, the operation should not be postponed. Experience learns that a smaller risk is associated with an early intervention. The operation is performed in a technically easier way. Eventually, also the total duration of hospitalization is shorter. Despite the available antibiotics and the technical progress in cardiac surgery, mortality remains high. This is

    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.

    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.

    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.

  8. Aorto-right atrial fistula after ascending aortic replacement or aortic value replacement

    International Nuclear Information System (INIS)

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

    Full Text Available 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 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.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.

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

Los estudios llevados a cabo en nuestro país y en otros países demostraron que el perfil clínico del paciente ha cambiado. Existe mayor prevalencia de pacientes añosos con enfermedad degenerativa valvular, las endocarditis protésicas y nosocomiales son más frecuentes y aumentó la presencia del Staphylococcus aureus. Estos cambios podrían justificar la ausencia de disminución en la mortalidad de esta enfermedad y plantean la necesidad de encarar enfoques más agresivos de tratamiento mediante la confección de estudios prospectivos bien diseñados y controlados.In spite of the advance in diagnosis and antibiotic and surgical treatment, mortality of infective endocarditis remains high. 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 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.

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

  7. Infective Endocarditis during Pregnancy

    International Nuclear Information System (INIS)

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

Material and methods. 50 pts with IE (24 female, 26 male aged 16 to 60 years were included. Primary IE was diagnosed in 15, secondary - in 35 cases. 7 pts had acute and 43 — subacute course. 40 pts had definite and 10 — probable IE. Results. Mean period till correct diagnosis establishment was 112± 116,5 days. Diagnostic difficulties were more frequent in subacute variant of IE (p=0,03. Heart diseases prevailed among cardiac risk factors (p=0,0l. Clinical picture of IE was very polymorphous. Glucocorticoids (GC were administered to 21 pts in addition to antibiotics due to signs of organ immunopatology and high laboratory measures of immune activity. Positive effect of glucocorticoids was achieved in 64% of pts. Conclusion. Development of immunological changes complicates timely diagnosis of IE and requires exclusion of different diseases including rheumatic pathology. IE treatment strategy does not exclude administration of GC low doses for prominent immunopathological signs in addition to massive antibacterial therapy.

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

    Full Text Available OBJECTIVE: To analyze the immune response in peripheral blood of patients with infective endocarditis. METHODS: We studied 10 patients with infective endocarditis, age range from 20 to 50 years-old, males and females, and 20 healthy subjects in the same age range. The diagnosis of the disease was based on the clinical picture, echocardiogram, and hemoculture based upon samples drawn and tested before the treatment started. The were no history of atopy or malnutrition, no autoimmune disease, and they were not using any immunosuppressant or antibiotic medication. RESULTS: The patients with endocarditis had significantly higher T and B lymphocyte, CD4+ and CD8+ cell counts, IgM and IgG serum levels, and C4 component of the complement than the control group; no significant difference concerning serum IgA and neutrophil oxidative metabolism; a significant decrease in C3, chemotaxis, and monocyte phagocytosis;cryoglobulins were detected in 66.6% of patients and they were formed by IgG, IgM, IgA, C3, and C4. CONCLUSION: The patients with infective endocarditis were immunocompetent in most sectors of immune response and, at a certain moment, an autoimmune component may be present.

    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.

De sete pacientes relatados, seis tiveram como achado radiológico um nódulo pulmonar e foram submetidos à biópsia pulmonar excisional para o diagnóstico. Em um paciente, a imagem radiológica não estava disponível para revisão e, portanto, não foi descrita no trabalho; o diagnóstico foi estabelecido pela biópsia transbrônquica.

    Full Text Available A hipertensão arterial pulmonar é classificada como idiopática ou secundária (associada a colagenoses, cardiopatias, hipertensão portal, tromboembolismo pulmonar e doenças da vasculatura pulmonar. O teste de vasorreatividade pulmonar é indicado para definir a melhor opção terapêutica. Muitas drogas têm sido utilizadas para a realização desse teste, sendo o óxido nítrico inalado a melhor opção, por apresentar ação específica pulmonar e meia vida muita curta (5-10 s. O resultado desse teste identifica candidatos à cirurgia cardíaca nas cardiopatias congênitas e candidatos ao uso de antagonista de cálcio nas outras formas de hipertensão pulmonar. A realização e interpretação do teste de vasorreatividade pulmonar exigem grande responsabilidade, e erros podem levar a decisões erradas e à ocorrência de óbitos.Pulmonary arterial hypertension is classified as idiopathic or secondary (associated with collagenoses, heart disease, portal hypertension, pulmonary thromboembolism, and pulmonary vascular diseases. Pulmonary vasoreactivity should be tested in order to define the best treatment option. Of the many drugs that have been used to test pulmonary vasoreactivity, inhaled nitric oxide is the best choice, due its specific pulmonary effect and very short half-life (5-10 s. The results of this test identify candidates for heart surgery among patients with congenital heart disease and candidates for the use of calcium antagonists among patients with other forms of pulmonary hypertension. Performing and interpreting the results of such tests are a great responsibility, since mistakes can lead to incorrect treatment decisions, resulting in the death of patients.

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

    2015-01-01

    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.

  16. Revisiting the surgical creation of volume load by aorto-caval shunt in rats.

    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.

    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. We report a case of a patient, who was treated before admission to the Clinic because of azotemia and oliguria suggesting renal failure.

    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.

    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. PMID:26953488

    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.

    Ninety cases of infective endocarditis seen over a 10-year-period at University College Hospital, Ibadan, are reviewed. The peak incidence was in the third decade and rheumatic heart disease was the commonest pre-existing lesion in 59 cases with subacute endocarditis. In most cases the source of infection was not known. In 41 of the 90 cases (44%) the diagnosis was made only at autopsy. The bacterial isolation rate was low, the commonest organisms being staphylococci, streptococci, micrococci and gramnegative bacilli. The overall mortality was 70%. A plea is made for increasing awareness of the disease and prompt institution of effective treatment. PMID:941246

    Aorto-esophageal fistula (AEF) is a rare but devastating complication of thoracic aorta endovascular repair (TEVAR). We report a case of a 64-year-old male who presented with chest pain and high CRP levels 10 months after TEVAR for a 9 cm diameter descending thoracic aortic aneurysm. The diagnosis of an AEF was confirmed and the patient was treated conservatively with broad spectrum antibiotics and total parental alimentation. After control of sepsis was achieved, esophagectomy with gastric tube reconstruction was performed and an omental pedicle was used to cover the aortic wall. No intervention to the aorta was made at that time due to the potentially infected mediastinum. The patient's recovery was uneventful and 2 years postoperatively he is in good condition and lives a normal life. Esophagectomy seems to be a mandatory stage of treatment in the setting of AEF. In cases where signs of graft infection are persistent, aortic surgery might be also necessary. PMID:24838140

    A 73-year-old man with a history of intermittent claudication for the previous six years visited our hospital. His ankle-brachial index (ABI) was very low on both sides, and computed tomography (CT) indicated bilateral aorto-iliac occlusive disease (AIOD). As he refused to undergo open surgery, endovascular treatment (EVT) was administered. After the first and second EVT sessions, the intermittent claudication improved completely. In addition, the ABI normalized (right: 1.01, left: 0.99), and CT demonstrated full expansion of the stents. His post-EVT course was uneventful for 18 months. The use of EVT to treat AIOD is technically feasible and may serve as a potential treatment option for patients with an inoperable condition. PMID:25876573

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

    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.

    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. PMID:25281630

    Management of patients with abdominal secondary aorto-entericfistulae (SAEF) complicating aortic graft replacement is controversial. We retrospectively analyzed the postope- rative and long-term outcomes of all consecutive patients operated on for SAEF betwveen 2002 and2012. All were managed by in situ replacement with a cryopreserved allograft and treatment of the affected digestive tract. Thirty-two patients (median age 65 years) underwent aortic replacement for SAEFa median of 5 years after initial aortic surgery. The fistulae were located in the duodenum (n = 20), small bowel (n = 6), colon (n = 5) or stomach (n = 1). Treatment of the digestive tract included suture (n = 16), resection with anastomosis (n = 12) covered by a defunctioning stoma (n = 1), and Hartmann's procedure (n = 3). Omentoplasty was performed in 18 patients (56 %), and 17 patients (53 %) had afeedingjejunostomy. Eight patients (25 %) died post-operatively, 3 with a recurrent aorto-enteric fistula. Fifteen (62.5 %) of the remaining patients developed 27 complications, including 6 patients (19 %) with severe morbidity (Dindo III-IV). The reoperation rate was 21 %. The median hospital stay was 33 days. During follow-up (median 15 months), no further patients had a recurrent aorto-enteric fistula. We conclude that surgery for SAEF is a major procedure associated with high mortality and morbidity. Good long-term results can be obtained by excision of the prosthetic graft with cryopreserved allograft replacement, and by management in a tertialy referral center with expertise in both vascular and digestive surgery.

    1998-01-01

    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.

    Full Text Available Infective endocarditis is a common clinical problem in industrialized countries. Risk factors include abnormal cardiac valves, a history of endocarditis, intracardiac devices, prosthetic valves and intravenous drug use. We report a case of polymicrobial infective endocarditis in a 33 year-old female with a history chronic heroin use caused by Neisseria sicca and Haemophilus parainfluenzae. We believe the patient was exposed to these microbes by cleansing her skin with saliva prior to injection. 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.

    2014-01-01

    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

    Although Escherichia coli is among the most common causes of Gram-negative bacteraemia, infectious endocarditis (IE) due to this pathogen is rare. A 67-y-old male without a previous medical history presented with a new mitral regurgitation murmur and persisting E. coli bacteraemia in spite of broad......-spectrum intravenous antibiotics. Transthoracic and transoesophageal echocardiography revealed a severe mitral endocarditis. E. coli DNA was identified from the mitral valve and the vegetation, and no other pathogen was found. The case was further complicated by spondylodiscitis and bilateral endophthalmitis. Extra......-intestinal pathogenic E. coli (ExPEC) are able to colonize tissue outside the gastrointestinal tract and contain a variety of virulence factors that may enable the pathogens to invade and induce infections in the cardiac endothelia.

Even though a transoesophageal echocardiography showed endocarditis of the aortic valve, blood cultures remained negative. Additional serological testing revealed a positive result for Bartonella henselae. Histology of the supraclavicular lymph node showed a reactive lymph node with a positive polymerase chain reaction (PCR) for Bartonella henselae. Prednisolone treatment was started in a dosage of 10 mg per day and rifampicin 600 mg/d in combination with doxycyclin 200 mg/d was given for 6 months. During therapy the patient gradually improved and signs of endocarditis disappeared on echocardiography. PMID:18714850

    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.

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.

    Full Text Available El edema pulmonar postobstructivo (EPPO es una complicación postoperatoria cuyo manejo adecuado depende de un diagnóstico etiológico correcto. El EPPO se clasifica en dos tipos. El tipo I es secundario a la obstrucción aguda de la vía aérea superior. Por su parte, el tipo II ocurre luego de corregir quirúrgicamente una obstrucción crónica de la vía aérea. Fisiopatológicamente, el mecanismo que explica el cuadro es una disminución marcada de la presión intersticial en el nivel pericapilar pulmonar resultante de la inspiración forzada. Lo anterior produce fuga capilar y el consecuente edema de pulmón. El manejo de este cuadro requiere de soporte respiratorio que incluye ventilación mecánica e incluso presión positiva al final de la espiración (PEEP. El pronóstico es muy bueno si el diagnóstico es correcto y oportuno. Se reportan 3 casos que ilustran la entidad, su diagnóstico y manejo.Postobstructive pulmonary edema (POPPE is a postoperative complication and its approach depends on an appropriate diagnosis. POPPE can be classified in two types. POPPE type I is caused by acute upper airway obstruction , and type II is due to chronic obstruction. The mechanism of this entity is a marked decrease in pericapilar interstitical pressure in the lung that results in capillary leakage and edema. Its treatment requires mechanical ventilatory support including positive end expiratory pressure (PEEP. Its prognosis is very good if the diagnosis is done appropriately. We report three cases that illustrate its diagnosis and treatment.

    We present the case of a 54-year-old male patient with Loeffler endocarditis. It is a rare disorder characterized by fibrous thickening of the endocardium leading to apical obliteration and restrictive cardiomyopathy resulting in heart failure, thromboembolic events or atrial fibrillation. To the best of our knowledge, this is the first case reporting the electrical silence of the right ventricular (RV) apex caused by fibrothrombotic thickening of this area. Under these circumstances RV apical implantation of an implantable cardioverter defibrillator (ICD) or pacemaker electrode may lead to unsuccessful stimulation of these devices. PMID:26980214

    Elder, Robert W; Baltimore, Robert S

    2015-09-01

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

  16. Repair of abdominal aortic aneurysms with aorto-uni-iliac stentgraft and femoro-femoral bypass.

    Smit, J G M; van Marle, J

    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.

    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.

We report a case of a 59-year-old woman, with  PVE and bacterial endocarditis (Streptococcus bovis successfully treated with linezolid. Linezolid is a bacteriostatic oxazolidinone antibiotic that has been proven to be effective for the treatment of patients with pneumonia, skin and soft tissue infections, and infections due to Gram-positive cocci. Linezolid is not yet recognised as a standard therapy for infective endocarditis, but its use becomes a necessity when infection is due to multidrug-resistant microorganisms.

    An adult with a large patent ductus arteriosus may present with fatigue, dyspnea or palpitations or in rare presentation with endocarditis. The case illustrated unique role of vegetation of endocarditis in hemolytic anemia in adult with patent ductus arteriosus (PDA). Despite treatment of endocarditis with complete course of appropriate antibiotic therapy and normality of C- reactive protein, erythrocyte sedimentation rate and leukocytosis and wellness of general condition, transthoracic echocardiography revealed large vegetation in PDA lumen, surgical closure of PDA completely relieved hemolysis, and fragmented red cell disappeared from peripheral blood smear. The 3-month follow-up revealed complete occlusion of PDA and abolishment of hemolytic anemia confirmed by clinical and laboratory examination.

    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.

    Few data have been published regarding the epidemiology and outcome of infective endocarditis (IE) in patients with chronic hepatic disease (CHD). A retrospective analysis of the Studio Endocarditi Italiano (SEI) database was performed to evaluate the epidemiology and outcome of CHD+ patients compared with CHD- patients. The diagnosis of IE was defined in accordance with the modified Duke criteria. Echocardiography, diagnosis, and treatment procedures were in accordance with current clinical practice. Among the 1722 observed episodes of IE, 300 (17.4 %) occurred in CHD+ patients. The cause of CHD mainly consisted of chronic viral infection. Staphylococcus aureus was the most common bacterial species in CHD+ patients; the frequency of other bacterial species (S. epidermidis, streptococci, and enterococci) were comparable among the two groups. The percentage of patients undergoing surgery for IE was 38.9 in CHD+ patients versus 43.7 in CHD- patients (p = 0.06). Complications were more common among CHD+ patients (77 % versus 65.3 %, p infection sustained by S. aureus, a prosthetic valve, diabetes and a neoplasia, and CHD. Being an intravenous drug user (IVDU) was a protective factor and was associated with a reduced death risk. CHD is a factor worsening the prognosis in patients with IE, in particular in patients for whom cardiac surgery was required. PMID:26690071

    The incidence of severe complications of the Neisseria gonorrhoeae infection has presented variations over recent decades since the advent of penicillin. Gonococcal endocarditis (GE) still remains an ever-present threat afflicting the society’s poor and sexually active young population. This entity frequently requires surgical intervention and usually exhibits a poor outcome. The interval between the onset of symptoms and the diagnosis does not usually exceed 4 weeks. One of the characteristics of GE is a proclivity for aortic valve involvement with large vegetation and valve ring abscess formation. The authors report the case of a young man with a 2-week history of fever, malaise, weakness, and progressive heart failure symptoms, who had no previous history of genital complaints or cardiopathy. The physical examination was consistent with acute aortic insufficiency, which was most probably of an infectious origin. The echocardiogram showed thickened aortic cusps and valve insufficiency. After hospital admission, the patient’s clinical status worsened rapidly and he died on the second day. The autopsy findings disclosed aortic valve destruction with vegetation and a ring abscess besides signs of septic shock, such as diffuse alveolar damage, acute tubular necrosis, and zone 3 hepatocellular necrosis. The blood culture isolated N. gonorrhoeae resistant to penicillin and ciprofloxacin. The authors call attention to the pathogen of this particular infectious endocarditis, and the need for early diagnosis and evaluation by a cardiac surgery team. PMID:27547739

    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 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.

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.

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.

    Full Text Available Se reporta los dos primeros casos de micetoma pulmonar por Scedosporium sp, en el Perú, tratados quirúrgicamente en el Hospital Nacional Hipólito Unanue. Se practicó resección pulmonar debido a micetoma pulmonar de donde se tomó muestras que fueron enviadas a microbiología y anatomía patológica para cultivo y estudio histopatológico. Se identificó el moho Scedosporium sp en dos pacientes con secuelas cavitarias por tuberculosis, quienes presentaron tos y hemoptisis de dos meses y tres años de evolución, respectivamente. Radiológicamente las cavidades estaban ocupadas por una "bola fúngica". La histopatología indicó presencia de abundantes hifas, indistinguibles de las de Aspergillus sp, mientras que la inmunodifusión para Aspergillus fue negativa.

    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

  16. Brain magnetic resonance findings in infective endocarditis with neurological complications

    International Nuclear Information System (INIS)

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

  17. Isolated pulmonic valve endocarditis presenting as neck pain

    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 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.

    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.

    O'Connor, Cormac T; Kiernan, Thomas J

    2015-05-01

    Infective endocarditis involving prosthetic valves accounts for 20% of all endocarditis cases. Rising in prevalence due to increasing placement of valvular prostheses, prosthetic valve endocarditis (PVE) is more difficult to diagnose by conventional methods, associated with more invasive infection and increased mortality. This report explores the existing literature in identifying a direct approach to the management of PVE; such as adjuncts to establishing a diagnosis (for instance positron emission tomography/computed tomography and radiolabeled leukocyte scintigraphy), the trends in specific pathogens associated with PVE and the recommended antimicrobials for each. The patterns of disease requiring surgical intervention are also highlighted and explored. In addition, a 5-year outlook offers consolidated knowledge on epidemiological trends of both culprit organisms and population subgroups suffering (and projected to suffer) from PVE. PMID:25865118

    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.

    Glomerulonephritis (GN) due to infective endocarditis (IE) is well documented, but most available data are based on old autopsy series. To update information, we now present the largest biopsy-based clinicopathologic series on IE-associated GN. The study group included 49 patients (male-to-female ratio of 3.5:1) with a mean age of 48 years. The most common presenting feature was acute kidney injury. Over half of the patients had no known prior cardiac abnormality. However, the most common comorbidities were cardiac valve disease (30%), intravenous drug use (29%), hepatitis C (20%), and diabetes (18%). The cardiac valve infected was tricuspid in 43%, mitral in 33%, and aortic in 29% of patients. The two most common infective bacteria were Staphylococcus (53%) and Streptococcus (23%). Hypocomplementemia was found in 56% of patients tested and ANCA antibody in 28%. The most common biopsy finding was necrotizing and crescentic GN (53%), followed by endocapillary proliferative GN (37%). C3 deposition was prominent in all cases, whereas IgG deposition was seen in <30% of cases. Most patients had immune deposits detectable by electron microscopy. Thus, IE-associated GN most commonly presents with AKI and complicates staphylococcal tricuspid valve infection. Contrary to infection-associated glomerulonephritis in general, the most common pattern of glomerular injury in IE-associated glomerulonephritis was necrotizing and crescentic glomerulonephritis.

    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.

    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.

    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.

    We discuss a case of a 20-year-old woman presenting with chest pain found to have a Hampton's hump on chest x-ray and corresponding wedge infarct on computed tomographic scan. 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.

    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.

    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.

    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.

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

    Full Text Available 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.

  3. Enterococcal Infective Endocarditis following Periodontal Disease in Dogs.

    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.

    2014-06-01

    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.

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.

    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.

    Extraction of the aorto-femoral vessel trajectory is important to utilize computed tomography angiography (CTA) in an integrated workflow of the image-guided work-up prior to trans-catheter aortic valve replacement (TAVR). The aim of this study was to develop a new, fully-automated technique for the extraction of the entire arterial access route from the femoral artery to the aortic root. An automatic vessel tracking algorithm was first used to find the centerline that connected the femoral accessing points and the aortic root. Subsequently, a deformable 3D-model fitting method was used to delineate the lumen boundary of the vascular trajectory in the whole-body CTA dataset. A validation was carried out by comparing the automatically obtained results with semi-automatically obtained results from two experienced observers. The whole framework was validated on whole body CTA datasets of 36 patients. The average Dice similarity indexes between the segmentations of the automatic method and observer 1 for the left ilio-femoral artery, the right ilio-femoral artery and the aorta were 0.977 ± 0.030, 0.980 ± 0.019, 0.982 ± 0.016; the average Dice similarity indexes between the segmentations of the automatic method and observer 2 were 0.950 ± 0.040, 0.954 ± 0.031 and 0.965 ± 0.019, respectively. The inter-observer variability resulted in a Dice similarity index of 0.954 ± 0.038, 0.952 ± 0.031 and 0.969 ± 0.018 for the left ilio-femoral artery, the right ilio-femoral artery and the aorta. The average minimal luminal diameters (MLDs) of the ilio-femoral artery were 6.03 ± 1.48, 5.70 ± 1.43 and 5.52 ± 1.32 mm for the automatic method, observer 1 and observer 2 respectively.

    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.

    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.

    2015-09-01

    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.

  16. Selection of dental procedures for antibiotic prophylaxis against infective endocarditis.

    1992-12-01

    A dental source of infection remains the most common identifiable risk factor in infective endocarditis and this may be particularly important in patients at 'high risk'. We therefore performed a questionnaire survey of dental practitioners to assess acceptance of The British Society of Antimicrobial Chemotherapy (BSAC) recommendations, especially with regards to selection of dental procedures for antibiotic prophylaxis. The results showed that the dental practitioners surveyed treated the 'high risk' patient group differently by extending the range of dental procedures covered by antibiotics but the BSAC only recommend that they be treated differently by hospital treatment and/or parenteral antibiotics. This must be an area of concern and deserves further attention, especially with regards to the need for wider publicity and the range of dental procedures that should be covered in the 'high risk' group where morbidity and mortality from infective endocarditis are higher.

    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.

    The endocardial vegetation which is formed in the course of bacterial endocarditis (BE) contains tissue factor (TF)-dependent procoagulant activity. Earlier studies showed that monocytes are the main source of TF in the vegetations. The TF activity (TFA) of vegetations isolated from Streptococcus sanguis-infected rabbits depended on the numbers of bacteria as well as monocytes in the vegetation. In this study, we investigated whether for Staphylococcus epidermidis, a frequent pathogen in BE, ...

    In the pathogenesis of bacterial endocarditis (BE), the clotting system plays a cardinal role in the formation and maintenance of the endocardial vegetations. The extrinsic pathway is involved in the activation of the coagulation pathway with tissue factor (TF) as the key protein. Staphylococcus aureus is a frequently isolated bacterium from patients with BE. We therefore investigated whether S. aureus can induce TF activity (TFA) on fibrin-adherent monocytes, used as an in vitro model of BE....

    Full Text Available Autopsy incidence of infective endocarditis during the past 50 years was analysed to review the changes in the clinico-pathologic pattern if any. 185 cases were recorded in a total of 39931 autopsies giving an average incidence of 0.46%. The cases were classified into groups I, II & III depending upon whether the endocarditis super-vened on normal hearts, diseased hearts or followed surgery, re-spectively. The fifty year period could be divided into three phases on incidence. First phase (1927-41 represented pre-antibiotic era in which group I cases predominated and causative organisms in 801" o f cases were virulent cocci such as staphylococci, haemolytic streptococci and pneumococci. In the second phase (1948-66 the general incidence was reduced by 50%. Group II cases predominat-ed and the most common etiologic agent was streptococcus viridans (40%. In the third phase (1967-76 the general incidence has reached again to preantibiotic level with coagulase positive staphy-lococci, Gram negative bacilli and fungi accounting for 90% of cases. Group III contributed significantly in this phase. The changes in incidence are primarily due to fall and rise in Group I cases. Incidence of rheumatic heart disease with endocar-ditis which mainly forms Group II is declining steadily in post-antibiotic era. There is no shift in the peak age incidence which remains in the 3rd decade. Males with rheumatic heart disease are more prone to infective endocarditis than similarly affected females. There was no change in frequency of involvement of various valves or sites of embolization.

    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.

  11. 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.

    1978-01-01

    It has been asserted that humoral immunity is an important potentiating factor in pathogenesis of infective endocarditis, in that prior immunization to certain bacteria may predispose the host to endocarditis caused by those organisms. If so, possible future vaccination of humans with streptococcal antigens for the prevention of dental caries might increase the susceptibility of the population to streptococcal endocarditis. To examine this hypothesis further, we immunized rabbits with killed Streptococcus sanguis or Streptococcus mutans. After complement-fixing antibody had developed, the rabbits were tested for susceptibility to experimental infective endocarditis. Rabbits with high titers of complement-fixing antibody to the infecting organism developed streptococcal endocarditis less often (13%) than animals with lower titers (69%; P less than 0.0002). These findings do not support the hypothesis that pre-immunization predisposes to infective endocarditis and lend no credence to the concept that vaccination of human subjects against dental caries might increase their susceptibility to streptococcal endocarditis. On the contrary, the results of these experiments indicate that specific antibody can confer relative immunity to infective endocarditis. PMID:730349

    Glomerulonephritis (GN) is an immunological phenomenon in bacterial endocarditis. These may be pauci-immune/vasculitic GN, post-infective GN, and sub-endothelial membranoproliferative glomerulonephritis. Each type of glomerulonephritis usually occurs in isolation. We report a case of infective endocarditis with dual existence of pauci-immune/vasculitic GN and post infective type of GN at the same time.

    Full Text Available Um bovino Guzerá, fêmea, adulto, com histórico de insuficiência cardíaca congestiva direita de duração de duas semanas, morreu durante o transporte ao hospital veterinário. À necropsia, o lobo pulmonar cranial esquerdo estava moderadamente aumentado de tamanho e firme. O parênquima do lobo afetado era branco e continha múltiplas áreas de 0,3 a 1,5cm de diâmetro, amareladas e caseosas. Alterações semelhantes foram observadas nos linfonodos mediastínicos e brônquicos, no pericárdio parietal, no epicárdio e na adventícia da artéria pulmonar. Histologicamente, a massa tecidual do lobo pulmonar era constituída por células epiteliais neoplásicas de padrão acinar, com duas ou mais camadas celulares, algumas com projeções papilares intraluminais. A anisocariose era acentuada, e o índice mitótico, moderado (dois a três por campo de maior aumento. Envolvendo as neoformações, observava-se abundante tecido conjuntivo fibroso. Focos de necrose e mineralização eram multifocais moderados. Alterações histológicas semelhantes foram observadas nos linfonodos brônquicos, nos mediastínicos, nos pericárdios visceral e parietal e na adventícia da artéria pulmonar. Com exceção do fígado com congestão generalizada crônica, não foram observadas alterações macro e microscópicas em outros órgãos.

    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.

    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.

    Full Text Available Candida endocarditis is an emerging infectious disease, usually involving patients with intravascular prosthetic devices, and associated with substantial morbidity and mortality. A 28-year-old primigravida at 32 weeks of gestation was admitted with low-grade fever and lower abdominal pain for 2 weeks. She had undergone open appendicectomy 2 months before admission. Echocardiogram showed a pedunculated 24 mm × 21 mm mass attached to the undersurface of anterior mitral leaflet near the tip and moderate mitral regurgitation. Repeated blood cultures showed growth of nonalbicans candida. She was immediately started on liposomal amphotericin and was taken up for surgery, but despite all efforts she succumbed to her illness.

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

    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.

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

    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.

    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.

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.

    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.

    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.

    2016-01-01

    Sixty years after its initial description, right-sided infective endocarditis (RSIE) still poses a challenge to all medical practitioners. Epidemiological data reveal a rising incidence attributable to the global surge in the number of intravenous drug users and the increased use of central vascular catheters and implantable cardiac devices. RSIE differs from left-sided infective endocarditis in more than just the location of the involved cardiac valve. They have different clinical presentations, diagnostic findings, and prognoses; hence, they require different management strategies. Cardiac murmurs and systemic emboli are usually absent in RSIE, whereas pulmonary embolism and its related complications dominate the clinical picture. Diagnostic delay of RSIE is secondary to the similarity in its initial presentation to other entities. Complications may ensue as a result of this delay. Diagnosis can be initially confirmed by using transthoracic echocardiography, except in patients with implanted cardioverter defibrillator, where a transesophageal echocardiogram is necessary. Various factors may increase mortality and morbidity in RSIE such as tricuspid valve vegetation size, fungal etiology, and low CD4 cell count in HIV patients. Oxacillin and vancomycin had been the traditionally used agents for the treatment of methicillin-susceptible and methicillin-resistant Staphylococcus aureus, respectively. More recently, daptomycin has shown promising results, which has led to its Food and Drug Administration (FDA) approval for the treatment of S. aureus bacteremia and associated RSIE. The aim of this article is to provide a comprehensive update on RSIE including epidemiology, pathogenesis, microbiology, diagnosis, management, and prognosis. PMID:26501991

    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.

    2006-01-01

    Full Text Available 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.

    2008-12-01

    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.

    Libman-Sacks (LS) endocarditis is one of the most common cardiac manifestations of systemic lupus erythematosus. Rarely, however, it can lead to serious complications, including severe valvular regurgitation or superimposed bacterial endocarditis. We describe the initial diagnostic challenges, clinical course, imaging studies and histopathological findings of a patient who presented with life-threatening lupus complicated by hemoptysis and respiratory failure secondary to a rare complication of LS endocarditis, acute mitral valve perforation. We review the current literature on valve perforation in the setting of LS endocarditis. In conclusion, although the disease is often asymptomatic and hemodynamically insignificant, it can result in serious and potentially fatal complications secondary to valve perforation, which may demand emergency surgical management.

    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.

    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 A necessidade de intubação e do uso de ventilação mecânica na prematuridade está relacionada à chamada lesão pulmonar induzida pela ventilação e à consequente displasia broncopulmonar. 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 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.

    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.

    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.

    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.

    Full Text Available La sospecha temprana, el diagnóstico precoz y el tratamiento agresivo son fundamentales para el manejo de la endocarditis infecciosa. Actualmente, los organismos que causan ésta enfermedad han cambiado respecto a los que antiguamente se describían en la literatura. Además, los métodos diagnósticos han avanzado hacia un reconocimiento más temprano de la misma. Se comentan las nuevas guías clínicas y ecocardiográficas que se han establecido para el seguimiento de estos pacientes. En este artículo se presentan las manifestaciones clínicas que presenta la endocarditis infecciosa hoy en día. Además, se reconoce la ecocardiografía como herramienta indispensable para el diagnóstico y manejo de la enfermedad. Se amplian los conceptos sobre las diferencias diagnósticos que se pueden obtener de un ecocardiograma transtorácico y uno transesofágico. Se presentan, además, los hallazgos que se deben buscar en cada uno de estos exámenes y cómo estos mismos se pueden utilizar para el seguimiento del paciente. Se revisa, en detalle, los organismos nuevos y atípicos que se empiezan a presentar en esta enfermedad; y las complicaciones que se ven relacionadas a los mismos. Las complicaciones atípicas de este padecimiento también son abordadas, así como el tratamiento para los agentes etiológicos más frecuentes.

    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.

    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.

    Erysipelothrix rhusiopathiae is mostly isolated in swine causing erysipelas. Human invasive infections due to E. rhusiopathiae remain poorly described and interestingly bacteraemia associated with endocarditis are a source of ineffective empirical antibiotherapy. We report a case of sepsis without endocarditis due to E. rhusiopathiae and a review of the literature.

    Full Text Available A falta de adesão e a não obediência aos tratamentos recomendados é um problema muito comum que preocupa e interfere no sucesso da assistência aos portadores de Doença Pulmonar Obstrutiva Crônica-DPOC. Este estudo comparou o perfil dos portadores de DPOC aderentes e não aderentes a um programa de reabilitação pulmonar. Métodos: Estudo observacional exploratório prospectivo, envolvendo24 portadores de DPOC do programa de Reabilitação Pulmonar, alocados em dois grupos conforme participação integral do tratamento proposto: Grupo Aderente (GA=18 sujeitos e Não-aderente (GN=06sujeitos. O tratamento ocorreu em 08 semanas, 3x/semana, com duração de 1 hora e 30 minutos, composto por equipe multiprofissional (fisioterapeuta, profissional de educação física, nutricionista, farmacêutica, psicólogo e médico pneumologista. Resultados: O GA não diferiu do GN quanto à situação sociodemográfica, antropométrica, capacidade cardiorrespiratória de exercício e função respiratória. GN apresentou mais comorbidades quando comparadas ao GA e em média maior quantidade de medicamentos utilizados. Todos os pacientes caracterizaram-se com redução da qualidade de vida e correlações entre a função cardiorrespiratória e qualidade de vida foi observada para ambos os grupos. Conclusão: Nossos resultados revelam queo estadiamento avançado da doença e o agravamento da sintomatologia foram fatores determinantes para a adesão dos portadores de DPOC ao programa de reabilitação pulmonar.

    The sensitivity and specificity of Tc-99m-labeled antibacterial antibody (Tc-99m Ab) for detecting bacterial endocarditis were evaluated in an experimental model. Rabbit-produced antistaphylococcal antibody was extracted using Rivanol and chemically labeled with Tc-99m. This Tc-99m Ab was injected intravenously in New Zealand rabbits 24 hr after producing Staphylococcus aureus endocarditis of the aortic valve. Imaging and tissue analyses were performed on the following day. All 11 animals developed S. aureus aortic-valve vegetations and showed increased uptake of Tc-99m Ab at the aortic valve, 118 times higher than at the uninfected tricuspid valve. Although high hepatic radioactivity and anatomic uncertainties interfered with in vivo delineation of these lesions, images of the excised hearts showed all affected valves. Two rabbits inoculated with Escherichia coli did not develop endocarditis and had little uptake of Tc-99m Ab, while six rabbits with enterococcal endocarditis had no uptake of the Tc-99m Ab in their vegetations. The findings suggest potential value of Tc-99m Ab on the rapid diagnosis of endocarditis.

    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 JUSTIFICATIVA E OBJETIVOS: O primeiro caso de proteinose alveolar pulmonar (PAP foi descrito por Rose em 1958, mas ainda é um distúrbio raro. PAP é caracterizada pela deposição de material lipoproteico secundário ao processamento anormal de surfactantes pelos macrófagos. Os pacientes podem ter dispneia progressiva e tosse, às vezes acompanhadas pelo agravamento da hipóxia, e seu curso pode variar de deterioração progressiva a melhora espontânea. Muitas terapias foram usadas, incluindo antibióticos, drenagem postural e ventilação com pressão positiva intermitente com acetilcisteína, heparina e soro fisiológico em aerossol. Atualmente, a base do tratamento é a lavagem pulmonar total (LPT. A LPT, embora seja geralmente bem-tolerada, pode estar associada a algumas complicações. RELATO DE CASO: Relatamos um caso de PAP grave durante o procedimento anestésico e as complicações no manejo da proteinose alveolar pulmonar em um paciente que havia sido submetido a múltiplas e alternadas lavagens de um dos pulmões ao longo de sete anos (os últimos três em nosso hospital, com melhora dos sintomas depois de cada tratamento.

    Full Text Available 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.

    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.

    Full Text Available Endocarditis due to Aspergillus infection is a rare complication in patients with hematological malignancies. Here, we present a case of aspergillus endocarditis in a patient with acute myeloid leukemia (AML successfully treated with antifungal therapy and surgical treatment. The patient was a 51 years old male, a known case of AML who was admitted to our medical center for evacuating his valvular vegetations and repairing his atrial septal defect. He underwent an open heart surgery to relinquish his thromboses and also received an antifungal regimen. The patient tolerated the procedure well and eight months after his surgery, the patient remains asymptomatic. Successful treatment of this severe case of aspergillus endocarditis justifies a multidisciplinary method to be as a safe and effective approach to manage these patients.

    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.

    While antineutrophil cytoplasmic antibody (ANCA) is often used as a diagnostic marker for certain vasculitides, ANCA induction in the setting of infection is much less common. In the case of infective endocarditis, patients may present with multisystem disturbances resembling an autoimmune process, cases that may be rendered even trickier to diagnose in the face of a positive ANCA. Though not always straightforward, distinguishing an infective from an inflammatory process is pivotal in order to guide appropriate therapy. We describe an encounter with a 43-year-old male with chronically untreated hepatitis C virus infection who featured ANCA positivity while hospitalized with acute bacterial endocarditis. His case serves as a reminder of two of the few infections known to uncommonly generate ANCA positivity. We also summarize previously reported cases of ANCA positivity in the context of endocarditis and hepatitis C infections. PMID:27366166

    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.

    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...

    Background.  Endocarditis is a rare manifestation of infection with Coccidioides. This is the first reported case of donor-derived Coccidioides endocarditis obtained from a heart transplant. Methods.  We present a unique case of donor-derived Coccidioides immitis endocarditis and disseminated infection in a heart transplant patient. We also conducted a review of the literature to identify other cases of donor-derived coccidioidomycosis in solid organ transplant recipients and reviewed their clinical characteristics. Results.  Fifteen prior cases of donor-derived coccidioidomycosis were identified. A majority of these cases were diagnosed by positive culture (83%). Mortality was high at 58%. Conclusions.  Clinicians should maintain a high index of suspicion for disseminated coccidioidomycosis in patients who received transplants with organs from donors with a history of residing in endemic regions.

  8. Analysis of clinical features and risk factors for infective endocarditis

    International Nuclear Information System (INIS)

    Objective: To analyze the clinical features of infective endocarditis (IE) and explore the risk factors for it's prognosis. Methods: Clinical data of 65 patients with IE were acquired retrospectively, and its causes, clinical characteristics, pathogenic microorganism, clinical outcomes were analyzed. Results: The major occurring heart diseases for IE in all patients were rheumatic heart disease, congenital heart disease, and there was no any previously known heart disease. The major clinical manifestations included fever and anemia. The major pathogenic bacteria is streptococcus, but percentage of other bacteria increased gradually. Thirteen patients were refractory, in hospital. Haematoglobin and seralbumin were significantly lower, and leucocyte, hsCRP, erythrocyte sedimentation were significantly higher in refractory group. Anaemia, lower seralbumin, higher hsCRP were independent predictors for bad prognosis. Conclusion: The proportion of rheumatic heart disease is decreasing as one of the risk factors for IE in recent years. Streptococcus is major pathogen of IE, and the mortality of IE is still very high. Anaemia, lower seralbumin, higher hsCRP are independent predictors for bad prognosis. (authors)

Negative HIV serology, blood count within normal range of leukocytes/neutrophils and lymphocytes, normal fractions of the complement, normal level of immunoglobulins for the age; lymphocyte immunophenotyping was also within the expected values. Thymus image was normal at chest MRI. No catheters were required. Identification of K. roseawas essential to this case, allowing the differentiation of coagulase-negative staphylococci and use of an effective antibiotic treatment. Careful labo- ratory analysis of Gram-positive blood-born infections may reveal more cases of Kocuria spinfections in immunocompetent patients, which may collaborate for a better understanding, prevention and early treatment of these infections in pediatrics.

    A 38-year-old Caucasian man with uncontrolled diabetes mellitus type 2 was admitted with a 1-week duration of fevers, chills, and a non-productive cough. 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. PMID:27124171

    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.

    Thirty-two children with 33 episodes of infective endocarditis were admitted into the paediatric unit of Ahmadu Bello University Teaching Hospital, Zaria during an 8-year period (January 1982-December 1989). Thirty (94%) had underlying heart disease. Rheumatic heart disease was the pre-existing anomaly in 21 (66%) while congenital cardiac anomalies were detected in nine (28%). Cardiac failure, changing murmur or persisting fever drew attention to the disease. Bacterial isolation was achieved in 19 patients (58%), staphylococci in 11, and salmonella was found in three children. Others included Acinetobacter spp. in two patients, one of whom had a mixed infection involving alpha haemolytic streptococcus whereas three children had Klebsiella, pseudomonas or alpha haemolytic Streptococcus, respectively. Only six patients (18%) recovered. Abscondment rates were high (28%) and overall hospital mortality was 47%. Intractable cardiac failure and neurological complications were the most important events heralding death. There is a need for increased awareness and improved facilities for prompt and effective treatment. PMID:1719922

    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.

    Full Text Available O transplante pulmonar consolidou-se como a melhor opção terapêutica para diversas pneumopatias terminais. O baixo número de doadores viáveis ainda persiste como uma grande limitação ao aumento do número de transplantes de pulmão, causando alta mortalidade na lista de espera. Diferentemente do transplante de outros órgãos sólidos, a maior limitação do transplante pulmonar não é o número absoluto de doadores e sim a viabilidade desses órgãos, que é reduzida devido às agressões ao pulmão ocasionadas pela morte encefálica e aos cuidados na UTI. Diversas são as propostas para o aumento do número de doadores: intensificação das campanhas de doação, o uso de doadores com coração parado, transplante pulmonar lobar intervivos e maior flexibilidade dos critérios para aceitação de doadores de pulmão. Todavia, a proposta que atrai a atenção de diversos grupos de transplante pulmonar é a perfusão pulmonar ex vivo, principalmente pela perspectiva de recuperação de pulmões inicialmente descartados. Esse sistema consiste na reperfusão e ventilação do bloco pulmonar isolado em um circuito de circulação extracorpórea modificado. Devido aos bons resultados apresentados e à perspectiva de aumento no número de órgãos aptos a transplante, diversos grupos têm estudado a técnica. Pesquisadores na Suécia, Canadá, Áustria, Inglaterra, Espanha e Brasil já possuem experiência sólida com o método e introduziram algumas variações. O objetivo deste artigo foi revisar o desenvolvimento, o estado da arte e as perspectivas futuras do modelo ex vivo de perfusão e recondicionamento pulmonar.Lung transplantation has come to be viewed as the best treatment option for various end-stage lung diseases.

    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.

    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.

    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.

    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.

    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

    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.

    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.

    2014-06-01

    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.

    Tropheryma whipplei endocarditis is an uncommon condition with very few series and 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

    Full Text Available Tromboembolia pulmonar aguda e exacerbação aguda de doença pulmonar obstrutiva crônica são doenças comuns. A doença pulmonar obstrutiva crônica é um fator clínico de risco para tromboembolia pulmonar aguda. As apresentações clínicas da tromboembolia pulmonar aguda e da exacerbação aguda da doença pulmonar obstrutiva crônica freqüentemente mimetizam-se tanto que pode ser difícil distingui-las. Anormalidades estruturais nos pulmões com doença pulmonar obstrutiva crônica tornam também difícil a interpretação de testes não invasivos de diagnóstico, como o mapeamento de ventilação e perfusão pulmonares. Assim, diagnosticar tromboembolia pulmonar aguda em pacientes com doença pulmonar obstrutiva crônica é uma tarefa desafiadora. Com o objetivo de atualizar o assunto e oferecer sugestões de conduta, nós avaliamos artigos abordando este tema, incluindo relatos e séries de casos, abordagens diagnósticas de tromboembolia pulmonar aguda e fizemos algumas reflexões. A probabilidade clínica de tromboembolia pulmonar aguda em cenários de doença pulmonar obstrutiva crônica é usualmente intermediária, o mapeamento de ventilação e perfusão pulmonares é predominantemente de probabilidade intermediária e os algoritmos de conduta os deveriam assim considerar.Pulmonary thromboembolism and exacerbation of chronic obstructive pulmonary disease are common conditions.

    Full Text Available A hipertensão pulmonar é uma complicação comum em pacientes com anemia falciforme. A despeito das elevações leves das pressões pulmonares desses pacientes, a morbimortalidade é alta e, em pacientes adultos com anemia falciforme, a hipertensão pulmonar é um fator de risco muito importante. A patogênese da hipertensão pulmonar relacionada à anemia falciforme é multifatorial e inclui hemólise, baixos níveis de óxido nítrico, hipóxia crônica, tromboembolismo, doença hepática crônica e asplenia. Na maioria dos pacientes, a hipertensão arterial pulmonar é a causa principal para as elevações na pressão arterial pulmonar, mas a hipertensão pulmonar venosa também é um fator contribuinte em alguns pacientes. Existem poucos estudos específicos avaliando os efeitos de tratamento para a hipertensão pulmonar em pacientes com anemia falciforme. É provável que a intensificação da terapia para a anemia hemolítica em todos os pacientes e o tratamento específico para a hipertensão pulmonar em pacientes com doença severa sejam benéficos. Estudos de grande porte avaliando o efeito do tratamento da hipertensão pulmonar em pacientes com anemia falciforme estão em andamento.Pulmonary hypertension is a common complication of sickle cell anemia. Despite the fact that the elevations in pulmonary artery pressures are slight, morbidity and mortality are high. In adult sickle cell anemia patients, pulmonary hypertension is emerging as a major risk factor for death. The pathogenesis of sickle cell anemia-related pulmonary hypertension is multifactorial, including hemolysis, impaired nitric oxide bioavailability, chronic hypoxemia, thromboembolism, chronic liver disease and asplenia. In the majority of patients, pulmonary arterial hypertension is the main cause of elevated pulmonary artery pressures. However, pulmonary venous hypertension also plays a role in a subgroup of patients. Specific data on the effects of treatment

    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)

    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

    Full Text Available INTRODUÇÃO: A fibrose pulmonar idiopática foi recentemente redefinida como pneumonia intersticial usual de etiologia desconhecida. O valor prognóstico dos achados histológicos deve ser reavaliado. OBJETIVO: Neste estudo foram correlacionados os achados histológicos e alguns dados clínicos e funcionais (duração dos sintomas, capacidade vital forçada, idade, sexo, hábito de fumar com a sobrevida. MÉTODO: Foram estudados 51 pacientes portadores de fibrose pulmonar idiopática. A média de idade foi de 66 ± 8 anos. Vinte e um pacientes eram do sexo feminino; 26 eram fumantes ou ex-fumantes. Todos apresentavam quadro de pneumonia intersticial usual na histologia. Grau de faveolamento, fibrose estabelecida, descamação, celularidade, espessamento vascular miointimal e focos fibroblásticos foram graduados por método semiquantitativo. RESULTADOS: A mediana do tempo de sintomas foi de 12 meses e a capacidade vital forçada inicial foi de 72 ± 21%. Por análise de risco proporcional de Cox, a sobrevida correlacionou-se, de maneira significativa (p < 0,05 e inversa, com o tempo de história, com a extensão dos focos fibroblásticos e com o espessamento miointimal da parede dos vasos. Focos fibroblásticos esparsos e espessamento miointimal envolvendo menos de 50% dos vasos foram preditivos de maior sobrevida. Sexo, idade, capacidade vital forçada, grau de inflamação e celularidade não se correlacionaram com a sobrevida. CONCLUSÃO: A análise semiquantitativa da biópsia pulmonar em portadores de fibrose pulmonar idiopática fornece informações prognósticas relevantes.

Objetivo: Descrever os casos de seqüestro pulmonar tratados no InCor e Hospital das Clínicas da FMUSP no período de 1987 a 1996. Método: Análise retrospectiva dos prontuários. Resultados: Foram tratados nove pacientes, sendo quatro mulheres e cinco homens; duas crianças e sete adultos. Infecção respiratória de repetição e hemoptise foram achados clínicos freqüentes nesses pacientes. Todos os casos eram intralobares. A principal localização foi no lobo inferior esquerdo (66%. Apenas um diagnóstico foi intra-operatório. Nos outros oito casos, o diagnóstico foi suspeitado pela radiografia de tórax (100% e confirmado pela arteriografia (77% e/ou tomografia computadorizada (66%. Lobectomia (77% foi o principal tratamento cirúrgico, com baixa morbidade pós-operatória e sem mortalidade. Exame anatomopatológico foi realizado em sete casos e confirmou a doença. Conclusões: O seqüestro pulmonar é uma entidade incomum, em que a tomografia computadorizada e a arteriografia são os exames que mais informações oferecem para um diagnóstico definitivo e seguro. A ressecção do tecido envolvido leva a excelentes resultados.

    Full Text Available A hipertensão pulmonar tromboembólica é a única forma potencialmente curável de hipertensão pulmonar, nos casos passíveis de resolução cirúrgica. O desenvolvimento da técnica de tromboendarterectomia possibilitou a melhora significativa da sobrevida dos pacientes portadores de hipertensão pulmonar tromboembólica, assim como a resolução do quadro hipertensivo na maioria absoluta dos pacientes operados. Nos últimos anos, tornou-se possível a definição de critérios mais claros para a indicação cirúrgica, assim como de critérios prognósticos, o que determinou uma diminuição significativa do risco cirúrgico associado ao procedimento.Chronic thromboembolic pulmonary hypertension is the only type of pulmonary hypertension that is potentially curable, assuming that the patient in question is a good candidate for surgery. The development and implementation of the thromboendarterectomy technique has, in most cases, allowed the hypertensive state to be resolved and has therefore increased survival among such patients. In recent years, more well-defined criteria for identifying patients for whom surgery is indicated, as well as the identification of prognostic markers, have made it possible to decrease surgical risk significantly.

    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.

    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.

    The epidemiologic profile of infective endocarditis has changed substantially over the past few years, especially in industrialized countries. Our study evaluates the clinical and pathologic characteristics of infective endocarditis patients treated by cardiac surgery in China during a 12-year period. We retrospectively evaluated 220 surgically treated infective endocarditis patients and analyzed their changes from the beginning of 1998 through 2009. The mean age of the patients increased from 36.9 to 42.7 years during those 12 years (P=0.036). The chief predisposing disease was congenital heart disease (32.8%), rather than rheumatic heart disease (13.2%); this rate did not change significantly during the 12 years. The prevalent congenital lesion was bicuspid aortic valve, the rate of which (55.6%) increased significantly over the 3 time intervals studied (P=0.016). The frequency of infective endocarditis after non-dental surgical and nonsurgical intervention was significantly greater (23.3%) during 1998 through 2001, compared with the 2 intervals that followed (9%; P=0.019). Streptococcus viridans was the most frequent causative agent overall (25.6%). Forty-seven of the 220 patients (21.4%) carried the clinical diagnosis of some other form of heart disease before surgery, but at surgery they were found to have infective endocarditis as the fundamental disease process. Of 47 patients, 33 (70.2%) had either very small or no vegetations but had focal necrosis and inflammation of valve tissue that supported the diagnosis of infective endocarditis.

    Full Text Available OBJETIVO: Apresentar a evolução de quatro casos de proteinose alveolar pulmonar atendidos na Faculdade de Medicina da Universidade Estadual de Londrina, enfocando a importância da lavagem pulmonar total como tratamento de escolha. MÉTODOS: Trata-se de um estudo retrospectivo de quatro pacientes, sendo três do gênero feminino, com idades de 22 a 34 anos, e histórias semelhantes de dispnéia progressiva e tosse seca. O diagnóstico final foi realizado por biópsia pulmonar a céu aberto. A lavagem pulmonar total foi realizada em três pacientes em centro cirúrgico, com anestesia geral e sonda de duplo lúme. RESULTADOS: Um paciente apresentou regressão espontânea da proteinose alveolar pulmonar, não sendo necessária a lavagem pulmonar. Nos outros três casos, o número de lavagens variou: uma única lavagem unilateral com remissão completa do quadro bilateralmente, três lavagens sem melhora significativa e quatro procedimentos intercalados com períodos de melhora. CONCLUSÃO: Constatamos em nossa casuística que a lavagem pulmonar se mostrou eficiente, apesar de alguns pacientes apresentarem certa resistência ao procedimento, enquanto que outros podem ter remissão completa da doença.OBJECTIVE: The aim of this study was to present the evolution of four patients presenting pulmonary alveolar proteinosis and treated at the State University of Londrina School of Medicine.

  9. Are valve repairs associated with better outcomes than replacements in patients with native active valve endocarditis?

    2014-12-01

    A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether valve replacement was associated with higher morbidity and mortality rates than valve repair in patients with native active valve endocarditis. Altogether 662 papers were found using the reported search, of which 7 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Traditionally, valve replacement has been the standard therapy for valve endocarditis when surgical treatment is indicated. But now valve repair is increasingly used as an alternative, which may avoid disadvantages of anticoagulation, lower the risk of prosthetic infection and improve postoperative survival. To compare outcomes of these two treatments between studies can be difficult because most of related papers contain raw data on prosthetic valve endocarditis or healed endocarditis, which were excluded from our manuscript. Studies only analysing the outcomes of either of these treatments without the comparison of valve repair and replacement were also excluded. Finally, seven papers were identified. The American Heart Association/American College of Cardiology 2006 valvular guidelines recommended that mitral valve repair should be performed instead of replacement when at all possible. In three of the seven studies, there were significant differences between valve repair and replacement in long-term survival. One study found that aortic valve repair offered better outcomes in freedom from reoperation at 5 years (P = 0.021) and in survival at 4 years (repair vs replacement 88 vs 65%; P = 0.047). One study reported that there was improved event-free survival at 10 years in the mitral valve repair group (P = 0.015), although there was more previous septic embolization in this group. In one study, early and late mortality

    A case of WPW syndrome combined with mitral regurgitation caused by infective endocarditis underwent surgical division of accessory pathway and mitral valve replacement preserving posterior leaflet simultaneously. A 56-years old woman suffered atrial fibrillation with pseudo VT and cardiac failure caused by mitral regurgitation. Electro-physiological study (EPS) revealed accessory pathway in postero-lateral wall in left atrium and atrio-fascicular pathway like James bundle in AV node. ECHO cardiography showed mitral valve prolapse and severe regurgitation. Accessory pathway was divided surgically and deep freeze coagulation was followed. Perforation of anterior leaflet and chordal rupture of posterior leaflet caused by infective endocarditis were repaired by annuloplasty (Kay and McGoon method) at first, but regurgitation retained moderately. After re-clamping of aorta, mitral valve was replaced with prosthesis (SJM 29 mm) preserving posterior leaflet. Postoperative examination revealed division of accessory pathway and no regurgitation of mitral prosthesis. PMID:2348136

    Infective endocarditis could present with a plethora of signs and symptoms. Among the rarity of its presentation is acute confusion associated with neurological deficits, mimicking stroke especially in the young population. We report a case of a 33-year-old young man with acute right-sided hemiparesis and confusion 2 weeks after  tooth extraction. The brain CT and MRI was consistent with new infarction on the left middle and anterior cerebral arteries' territory. Echocardiography unveiled the existence of posterior mitral valve leaflet vegetation. Blood culture grew Group B beta-haemolytic Streptococcus, sensitive to penicillin. Two weeks of intravenous gentamicin with 6 weeks of intravenous benzylpenicillin were administered. In this case report, we highlight the importance of recognition of infective endocarditis in a young patient presenting with cerebrovascular accident following tooth extraction.

    2016-01-01

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

    The enterococcal surface protein Esp, specifically linked to nosocomial Enterococcus faecium, is involved in biofilm formation. To assess the role of Esp in endocarditis, a biofilm-associated infection, an Esp-expressing E. faecium strain (E1162) or its Esp-deficient mutant (E1162Δesp) were inoculated through a catheter into the left ventricle of rats. After 24 h, less E1162Δesp than E1162 were recovered from heart valve vegetations. In addition, anti-Esp antibodies were detected in Esp-positive E. faecium bacteremia and endocarditis patient sera. In conclusion, Esp contributes to colonization of E. faecium at the heart valves. Furthermore, systemic infection elicits an Esp-specific antibody response in humans.

    Moores, Aimee E; Cahill, Michael S; Villines, Todd C

    2016-01-01

    Aortic mycotic aneurysms are a rare but life-threatening potential complication of infective endocarditis. Rapid deterioration of the vascular wall in highly focal areas makes these pseudoaneurysms particularly prone to rupture, resulting in uncontrolled aortic hemorrhage. While computed tomography angiography (CTA) is the imaging modality of choice for the evaluation of mycotic aneurysms, it is not routinely performed in patients with known or suspected infective endocarditis (IE). However, current valvular heart disease guidelines support the use of cardiac CTA in cases of IE and suspected perivalvular extension when there is inadequate or ambiguous visualization on echocardiography. Here, we describe a case of IE in which cardiac CTA was used for two purposes: to assess perivalvular complications and to define coronary anatomy in a patient with a suspected embolic myocardial infarction. Subsequent detection of an aortic root mycotic aneurysm not previously demonstrated on transthoracic or transesophageal echocardiography allowed for timely and uncomplicated surgical intervention, while avoiding invasive coronary angiography.

    We report a case of severe aortic bicuspid valve endocarditis, revealed by global cardiac failure without fever, in a 38-year-old man who had developed cerebral mycotic aneurysms nine months earlier. PCR analysis of the excised aortic valve and serological tests (even 9 months earlier) were positive for Bartonella henselae. A combination of intravenous then oral doxycyclin at 200mg/day and intravenous gentamycin at 90mg/day was given for 6 and 2 weeks respectively. The evolution was favorable on follow-up, 12 months after completion of the therapy. Only 49 cases of B. henselae endocarditis have been reported to date, none with associated mycotic aneurysm but most often located on the bicuspid aortic valve, and usually with severe valvular damage due to late diagnosis.

    Here, we report for the first time that the Streptococcus sanguinis nox gene encoding NADH oxidase is involved in both competition with Streptococcus mutans and virulence for infective endocarditis. An S. sanguinis nox mutant was found to fail to inhibit the growth of Streptococcus mutans under microaerobic conditions. In the presence of oxygen, the recombinant Nox protein of S. sanguinis could reduce oxygen to water and oxidize NADH to NAD(+) The oxidation of NADH to NAD(+) was diminished in the nox mutant. The nox mutant exhibited decreased levels of extracellular H2O2; however, the intracellular level of H2O2 in the mutant was increased. Furthermore, the virulence of the nox mutant was attenuated in a rabbit endocarditis model. The nox mutant also was shown to be more sensitive to blood killing, oxidative and acid stresses, and reduced growth in serum. Thus, NADH oxidase contributes to multiple phenotypes related to competitiveness in the oral cavity and systemic virulence. PMID:26930704

    Full Text Available The diagnosis of systemic lupus erythematosus (SLE depends on clinical evidence of renal, rheumatologic, cutaneous, and neurologic involvement, supported by serological markers. A previously healthy 14-year-old girl presented with Libman-Sacks endocarditis involving the aortic valve as the first manifestation of SLE. Even though she did not satisfy the American College of Rheumatology criteria for diagnosing SLE, she had anemia, proteinuria, elevated erythrocyte sedimentation rate, low complement 4 (C4 levels, and strongly positive antinuclear antibody titer. A renal biopsy showed stage IV lupus nephritis. Treatment was initiated with immunosuppressants and steroids. This type of presentation may be misdiagnosed as infective endocarditis missing the underlying collagen vascular disease.

    @@ Loeffler endocarditis is clinically presented as restrictive cardiomyopathy, which is the least common of the three major categories of cardiomyopathic disorders.1 The endomyocardial fibrosis was considered as its main pathophysiologic changes.2-4 Generally speaking, the characteristics include thickening of the apex and inflow tracts of one or both ventricles, and the papillary muscle and chordae tendineae also can be involved in some cases. The onset of apical thrombosis is very common. In the aspect of showing all of these characteristics, ultrasound cardiography (UCG) has low diagnostic accuracy (not more than 80%);5 CT has been reported rarely; cardiac magnetic resonance (CMR) imaging has dramatic advantages. We present the CMR findings in a typical case of Loeffler endocarditis pre- and post-operation.

    This case report describes the unusual presentation of a previously very well woman with Streptococcus agalactiae endocarditis in the emergency department. History, examination and preliminary laboratory and radiological investigations supported a diagnosis of acalculous cholecystitis, for which she was given intravenous broad spectrum antimicrobial therapy. One day following admission, the patient deteriorated and became unresponsive. Subsequent MRI of the brain revealed multiple bihemispheric cerebral emboli and a large, mobile mitral valve thrombus was visualised on her transoesophageal echocardiogram. S agalactiae was cultured from venous blood samples and her antimicrobial cover was adjusted accordingly. Despite her presumed guarded prognosis, this patient made a remarkable recovery. To our knowledge, the association of S agalactiae endocarditis with acalculous cholecystitis has not been previously described.

A histopatologia de material de biópsia pulmonar identificou basicamente uma arterite pulmonar característica, inflamação granulomatosa atípica provocada principalmente por vermes e raros ovos de S. mansoni envolvidos por escassa reação inflamatória. Para explicar a origem de constelação clínica toxi-infectuosa, foram afastadas as hipóteses de associação da esquistossomose a concausas infectuosas ou não, mas de curso febril, e a superposição de uma forma toxêmica sobre outra crônica pré-existente. Com base em dados clínicos, particularmente em subsídios da laparoscopia, e anatômicos, concluiu-se tratar o caso de uma forma crônica de esquistossomose reativada, provavelmente em virtude de alterações imunológicas inusitadas do hospedeiro. Ao que tudo parece indicar, o desvio de ovos e de vermes aos pulmões deveu-se à sindrome de hipertensão portal, cujos shunts entre a circulação portal e sistêmica determinaram a rota preferencial da migração.

    Streptococcus bovis group and Enterococcus spp. share phenotypic characteristics and intestinal habitat. Both have been associated with endocarditis and colorectal neoplasm (CRN). We studied all cases of endocarditis diagnosed between 1988 and 2014 in our centre and caused by S. bovis (109, 48.8 % of the bacteremia) and by Enterococcus spp. (36, 3.4 % of the bacteremia). Patients were seen until death or during a long-term follow-up, in order to rule out a concomitant CRN. The 109 cases of S. bovis endocarditis (SbIE) compared with the 36 caused by enterococci showed: a higher proportion of males (91 % vs. 72 %, p=0.005), more multivalvular involvement (28 % vs. 6 %, p=0.004), embolic complications (44 vs. 22 %, p=0.02) and colorectal neoplasm (64 % vs. 25 %, p=0.001). SbIE showed fewer co-morbidities (32 vs. 58 %, p=0.005), and less frequently urinary infection source (0 vs. 25 %, p=0.001) and healthcare-related infection (2 vs. 44 %, p=0.001). A total of 123 patients were followed up for an extended period (mean: 65.9 ± 57.5 months). During the follow-up, 6 of 28 (21 %) cases with enterococcal endocarditis and 43 of 95 (45.2 %, p=0.01) cases with SbIE developed a new CRN. These neoplasiae appeared a mean of 60.4 months later (range 12-181 months). Among the 43 cases with SbIE and CRN, 12 had had a previously normal colonoscopy and 31 had had a previous CRN and developed a second neoplasm. Cases of SbIE present important differences with those caused by Enterococcus spp. Colonoscopy must be mandatory both in the initial evaluation of SbIE, as during the follow-up period.

Here, we present a unique case of late aortic graft infection 5 years after insertion secondary to mitral valve endocarditis, resulting from cellulitis in a patient with severe venous varicosities. A 63-year-old male presented for severe low back pain, constipation, and low-grade fever. An abdominal computed tomography scan with oral and intravenous contrast showed a normal spine and urinary tract. Blood and urine cultures, done at the same time, grew Staphylococcus aureus. A transesophageal echocardiogram confirmed the diagnosis of endocarditis. Subsequently, a gallium scan showed increased uptake in the vertebral bodies, aortic graft, left patella, and left ankle. After 3 months of antibiotic therapy, the patient's low back pain resolved with normalization of his laboratory values. He remained free of infection at a 2-year follow-up. We reviewed the literature concerning the atypical presentation of infective endocarditis, with a focus on distant metastases at initial presentation, such as osteomyelitis and aortic graft infection, as well as the different treatment modalities. This report describes successful medical treatment with intravenous followed by oral antibiotics for an infected endovascular graft without any surgical intervention.Keywords: endocarditis, osteomyelitis, aortic graft infection, septic emboli, endovascular abdominal aortic aneurysm repair (EVAR

    Ischemic stroke is a common complication of infective endocarditis (IE), occurring in 20-40% of left side IE cases. In these subsets, anticoagulation therapy may provoke hemorrhagic transformation (HT) of ischemic stroke, and complications of this magnitude deteriorate the clinical course for IE patients. However, in cases of IE complicated with a mechanical prosthetic valve, the physician can be concerned over the maintenance of anticoagulation due to the risk of thrombotic complication. Acc...

    Background: High morbidity and mortality characterize patients suffering infective endocarditis (IE). The treatment of IE has undergone significant changes within ten years but it is not known whether mortality has decreased and which factors are determinant of the outcome.Objectives: Our aim was to evaluate the prognostic significance of clinical characteristics and outcomes of IE.Methods and Results: 312 definite cases of IE diagnosed using the Duke criteria were evaluated. Overall in-hospi...

    Due to the emergence of Staphylococcus aureus with reduced vancomycin susceptibility, newer antibiotics, including daptomycin, have been used to treat methicillin-resistant S aureus infections. Daptomycin is a cyclic lipopeptide that is approved to treat S aureus bacteremia and right-sided endocarditis, and reports of S aureus with reduced susceptibility to daptomycin are infrequent. To our knowledge, the present report describes the first Canadian case of daptomycin-nonsusceptible, vancomyci...

    A mycotic popliteal aneurysm (MAAP) is a very rare condition [1]. We describe a 87-year-old Caucasian male who presented with a MAAP of the right leg due to an enterococcus mitral valve endocarditis. The aneurysm was excised and a reversed vein graft was interposed between the normal popliteal artery and the posterior tibial artery. A second vein graft was interposed between the first graft and the anterior tibial artery.

    Valvular heart diseases in Africa affect mainly children and young adults and are a result of rheumatic fever. Rheumatic fever is a preventable disease, but in Africa the combination of a lack of resources, lack of infrastructure, political, social and economic instability, poverty, overcrowding, malnutrition and lack of political will contributes to the persistence of a high burden of rheumatic fever, rheumatic valvular heart diseases and infective endocarditis. Combating and eradicating rhe...
