    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. PMID:23021600

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

    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.

  3. 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)

    Enlarged bronchial arteries and/or systemic-to-pulmonary collaterals have been frequently demonstrated in association with transposition of the great arteries. They are usually clinically silent, although they might be large enough to cause accelerated pulmonary vascular obstructive disease or symptomatic cardiac volume overload after surgical repair. We report on a low-weight neonate with transposition of the great arteries and intact ventricular septum who showed a stormy postoperative course because of multiple aorto-pulmonary collaterals early after a successful arterial switch operation. Percutaneous coil embolization of these anomalous vessels resulted in sudden weaning from mechanical ventilation and hospital discharge in a few weeks. PMID:18185950

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

    Full Text Available Linfangioleiomiomatose pulmonar (LAM é uma doença rara, de etiologia desconhecida, que basicamente afeta mulheres jovens no período fértil de sua vida. Clinicamente, manifesta-se através de dispnéia progressiva, pneumotórax de repetição, tosse seca e, menos freqüentemente, por quilotórax e escarros hemoptóicos. Essas alterações surgem devido à proliferação anormal de células de músculo liso no parênquima pulmonar, linfonodos e em outros tecidos. Mais recentemente, estudos citogenéticos verificaram a presença de mutações do gene TSC-2 em células de angiomiolipoma renal e linfonodos abdominais de pacientes com LAM, indicando uma possível origem para as lesões hamartomatosas da doença. Radiologicamente, caracteriza-se pela presença de infiltrado intersticial reticulonodular e sinais de hiperinsuflação ao radiografia de tórax.

    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.

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.

  20. 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.

    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.

    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.

    2015-01-01

    Infective endocarditis (IE) is a life-threatening condition with adverse consequences and increased mortality, despite improvements in treatment options. Diagnosed patients usually require a prolonged course of antibiotics, with up to 40-50% requiring surgery during initial hospital admission. We report a case of a 42-year-old intravenous drug user who presented feeling generally unwell, with lethargy, rigours, confusion and a painful swollen right leg. He was subsequently diagnosed with Proteus mirabilis endocarditis (fulfilling modified Duke criteria for possible IE) and deep vein thrombosis (DVT). He was successfully treated with single antibiotic therapy without needing surgical intervention or requiring anticoagulation for his DVT. Proteus endocarditis is extremely uncommon, with a limited number of case reports available in the literature. This case illustrates how blood cultures are invaluable in the diagnosis of IE, especially that due to unusual microorganisms. Our case also highlights how single antibiotic therapy can be effective in treating Proteus endocarditis. PMID:26611486

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

    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....

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

  8. Acute Haemophilus parainfluenzae endocarditis: a case report

    Full Text Available Abstract Introduction Numerous pathogens can cause infective endocarditis, including Haemophilus parainfluenzae. H. parainfluenzae is part of the H. aphrophilus, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella kingae group that may cause about 3% of the total endocarditis cases, and is characterized by a subacute course and large vegetations. Case presentation Acute H. parainfluenzae endocarditis developed in a 54-year-old woman, with no underlying predisposing factors. The patient presented with fever of 3 days duration and a severe headache. Magnetic resonance imaging of the brain revealed multiple cerebral emboli with hemorrhagic foci. Upon suspicion of endocarditis, cardiac transesophageal ultrasonography was performed and revealed massive vegetations. The patient underwent emergency mitral valve replacement, and was further treated with ceftriaxone. Blood cultures grew H. parainfluenzae only after valve replacement, and a 6-week course of ceftriaxone was prescribed. Conclusion We underline the typical presentation of large vegetations in H. parainfluenzae endocarditis, which are associated with embolic phenomena and resulting severity. Although the majority of the few cases reported in the literature are subacute in progress, our case further underlines the possibility that H. parainfluenzae endocarditis may develop rapidly. Thus, awareness of the imaging characteristics of the pathogen may enhance early appropriate diagnosis and therapeutic response.

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

  13. Prevention of endocarditis in the Nordic countries.

    Science.gov (United States)

    Gutschik, E

    1995-04-01

    Bacterial endocarditis as the consequence of an iatrogenic bacteraemia has been recognized for a long time in the Nordic countries, and national recommendations were issued by groups of experts. It is generally agreed that antibiotic prophylaxis is needed in patients with high-risk conditions and that the maintenance of healthy gums and teeth is of major importance. Investigations, however, reported poor level of compliance, and pointed out that the procedural/practical aspect of interactions between patients, dentists and physicians have largely been neglected. In order to improve the level of compliance an 'endocarditis risk' card has been produced, and there has been a remarkable degree of harmonization of chemotherapeutic regimens recommended by the national organizations. Generally, a single dose of prophylaxis is recommended, because there is little evidence that antibiotic levels in humans must be maintained more than 6-7 h for effective prevention of endocarditis, and because compliance with a multiple dose regimen is highly questionable.

    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

    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

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

    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

    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 52-year-old male presented with recurrent hematemesis. A computer tomography scan showed a sealed rupture of the AAA adjacent to the duodenum. At surgery, a coin-sized PAEF was noted. The aorta was replaced with a Dacron graft in situ . Histological examination revealed the characteristics of an inflammatory AAA. The postoperative course was uneventful, and there has been no evidence of infection during a follow-up period of 3 years.

    We 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.

    Infective endocarditis (IE) is an infection of the endocardium that involves valves and adjacent mural endocardium or a septal defect. Local complications include severe valvular insufficiency, which may lead to intractable congestive heart failure and myocardial abscesses. If left untreated, IE is generally fatal. Diagnosing IE can be straightforward in patients with the typical oslerian manifestations such as bacteremia, evidence of active valvulitis, peripheral emboli, and immunologic vascular phenomena. In the acute course, however, the classic peripheral stigmata may be few or absent, particularly among intravenous drug abuse (IVDA) patients in whom IE is often due to a S. aureus infection of right-sided heart valves. We present a complicated case of a very aggressive native aortic valve MSSA (methicillin sensitive Staphylococcus aureus) IE in a young adult male with a past medical history of bicuspid aortic valve and IV drug abuse. His clinical course was complicated by aortic valve destruction and development of third-degree AV block, as well as an aorto-left atrial fistula requiring emergent operation for AV replacement and patch repair. The patient required two reoperations for recurrent endocarditis and its complications. PMID:26146571

    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

    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

    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

    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.

    Full Text Available A ossificação pulmonar difusa é uma condição rara, de etiologia desconhecida, na qual osso maduro é encontrado no parênquima pulmonar. É quase sempre descoberta como um achado incidental de autópsias. Freqüentemente afeta homens de meia-idade e é assintomática. Relata-se o caso de um paciente de 75 anos, que apresentou uma radiografia torácica com comprometimento pulmonar difuso e cujo diagnóstico foi baseado no exame histopatológico de fragmento pulmonar obtido através da biópsia a céu aberto, o qual demonstrou fibrose intersticial acentuada com ossificação do parênquima pulmonar.Diffuse pulmonary ossification is a rare condition of unknown pathogenesis in which mature bone is found in the pulmonary parenchyma. It is almost invariably discovered as an incidental finding at autopsy. Most commonly, it affects middle-aged men and is asymptomatic. We present the case of a 75-year-old man in which the chest X-ray showed diffuse interstitial infiltrate. Diagnosis was based on histopathological examination by open-lung biopsy, which revealed interstitial fibrosis with pulmonary ossification.

    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.

  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)

    Full Text Available La enfermedad pulmonar obstructiva crónica se ha convertido en una de las enfermedades crónicas atendidas con mayor frecuencia en la atención primaria de salud. 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 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.

    A modified rat model of endocarditis with catheterization for 2 days was established in female Lewis rats using different inocula of Enterococcus faecalis (strain no. EF 19) in order to measure IgG antibodies in serum during the course of infection. Increasing the inocula intravenously resulted in...... an increase in the CFU/g vegetation and the CFU/g spleen, the ID50 being about 10 CFU/ml and the ID90 about 1x10(2) CFU/ml. The lowest bacterial inoculum infecting 100% of the rats was 3x10(3) CFU/ml, and for further investigations we used this inoculum size. Rats were sacrificed on day 2, 5, 7, 9......, 11 and 28 after infection. The CFU/g vegetation and the CFU/g spleen increased until day 7 and then decreased. Serum samples were collected from 129 rats at different times after challenge. Three different ELISA systems were established to measure the IgG antibody responses: E. faecalis sonicate...

    2015-06-01

    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.

    2012-11-01

    Infective endocarditis despite advances in diagnosis remains a common cause of hospitalization, with high morbidity and mortality rates. Through literature review it is possible to conclude that polymicrobial endocarditis occurs mainly in intravenous drug abusers with predominance in the right side of the heart, often with tricuspid valve involvement. This fact can be associated with the type of drug used by the patients; therefore, knowledge of the patient's history is critical for adjustment of the therapy. It is also important to emphasize that the most common combinations of organisms in polymicrobial infective endocarditis are: Staphylococcus aureus, Streptococcus pneumonia and Pseudomonas aeruginosa, as well as mixed cultures of Candida spp. and bacteria. A better understanding of the epidemiology and associated risk factors are required in order to develop an efficient therapy, although PE studies are difficult to perform due to the rarity of cases and lack of prospective cohorts.

    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

    Left-sided valvular endocarditis (LSVE) is a common finding in slaughter pigs. The lesion is often associated with renal thromboembolism, but information on embolization to other organs is sparse. This study focuses on the presence and type of endocarditis-associated brain lesions (EABLs). The...... brains of 20 slaughter pigs with spontaneously arising LSVE and 11 controls were examined by sectioning half of a formalin-fixed brain into 4mm slices for histological examination. The aetiology of the endocarditis was determined by bacteriological and, in some cases, by fluorescence in......-situ hybridization examinations. These examinations identified 11 cases of Streptococcus suis, six cases of Erysipelothrix rhusiopathiae, one Streptococcus spp. and two cases that remained aetiologically undetermined. One of the S. suis cases had a dual infection with S. suis in the aortic valve lesions and...

    Full Text Available Abstract Introduction Stenotrophomonas maltophilia is an environmental bacterium increasingly involved in nosocomial infections and resistant to most antibiotics. It is important to recognize and efficiently treat infections with this bacterium as soon as possible. Case presentation We present a case of Stenotrophomonas maltophilia prosthetic valve endocarditis secondary to an indwelling catheter infection. The patient was cured without surgery. We review other cases of S. maltophilia endocarditis from the literature and describe the peculiarities of this case. Conclusion S. maltophilia endocarditis is a rare disease that is often hospital-acquired and related to an indwelling catheter infection. The high lethality is likely related to the intrinsic resistance of nosocomial bloodstream infections to commonly prescribed antibiotics.

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

    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.

    Full Text Available Objective: to analyze «rheumatic» symptoms in patients with infective endocarditis (IE and to investigate the specific features of the disease and hemodynamics in patients with prior rheumatic valvular disease Subjects and methods. The study included 184 patients with documented IE. The rate of “rheumatic” manifestations, such as joint, muscle, and skin lesions, visceral disorders, and laboratory changes, was estimated. Central hemodynamic parameters were studied in patients with IE in the presence of rheumatic heart disease. Results. Locomotor apparatus lesion was noted in 44.8% of the patients with IE, cutaneous hemorrhagic vasculitis in 18%, pericarditis in 10%, pleurisy in 19%, glomerulonephritis in 60%, leukopenia in 9%, thrombocytopenia in 32%, elevated C-reactive protein levels in 92%, circulating immune complexes in 72%. Glomerulonephritis and hemorrhagic vasculitis more frequently develop in injection drug users (p < 0.0001. Rheumatic heart disease was pre-ceded by IE in 24 patients (13% among the all patients and 27% among those with secondary IE. In the patients with secondary IE evolving in the presence of prior rheumatic heart disease, pulmonary artery systolic pressure (PASP and cardiac arrhythmia rates were significantly higher than those in primary IE (62.5 and 53 mm Hg; p < 0.05; 62 and 32%; p < 0.025. Conclusion. The «rheumatic» manifestations were common in patients with IE and require their differential diagnosis with rheumatic diseases. Their degree correlates with systemic in-flammatory disease activity. In the patients with IE and prior rheumatic heart involvement, PASP and the frequency of arrhythmias are higher than in those with primary IE.

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

  15. Correlations between aorto-popliteal bolus transit speed and aortic and popliteal bolus transit time during CT angiography of aortoiliac and lower extremity arteries

    International Nuclear Information System (INIS)

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

  1. 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.

    Full Text Available Kingella kingae , a HACEK (Haemophilus parainfluenzae, Aggregatibacter actinomycetemcomitans, Aggregatibacter aphrophilus, Cardiobacterium hominis, Eikenella corrodens, Kingella kingae organism, is a common resident of the upper airway in children; it has been associated with endocarditis in children with pre-existing heart conditions. This case report describes K. kingae endocarditis leading to valvular damage in a previously healthy 18-month-old child. Our patient developed a K. kingae bacteremia that was later complicated by meningitis, septic embolic stroke, and endocarditis of the mitral valve, leading to perforation of the posterolateral leaflet. The patient was initially treated conservatively with cefotaxime but, subsequently, required a mitral valve repair with a pericardial patch and annuloplasty. This report draws attention to the need for clinicians to be aware of the potentially serious complications of K. kingae infection in young children. If K. kingae infection is suspected then therapy should be initiated promptly with a β-lactam, followed by early echocardiographic assessment. This case also highlights the lack of specific guidelines available for K. kingae endocarditis.

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 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.

    A 63-year-old male patient with HIV disease presented with dyspnea and complete heart block, and was found to have aortic valve (AV) endocarditis secondary to Candida parapsilosis infection. Echocardiography demonstrated AV endocarditis and possible aortic root versus subannular abscess with moderate AV regurgitation (AR), a ventricular septal defect (VSD) and possible left ventricular to right atrial shunt (Gerbode defect). Large AV vegetations, subannular abscess with an acquired membranous VSD, Gerbode defect, and tricuspid annular abscess at the insertion of septal leaflet were noted intraoperatively. The patient underwent AV replacement with a stented bioprosthesis, two-sided VSD patch closure, and tricuspid valve (TV) repair with an annuloplasty ring. The left-sided patch closed the VSD and facilitated AV replacement, while the right-sided patch facilitated the TV repair. PMID:26901898

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

    Tan, S Y; Gill, G

    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.

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.

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.

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

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

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

    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.

  12. Effect of immunization on susceptibility to experimental Streptococcus mutans and Streptococcus sanguis endocarditis.

    Science.gov (United States)

    Durack, D T; Gilliland, B C; Petersdorf, R G

    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

    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. The MLDs of the aorta were 13.43 ± 2.54, 12.40 ± 2.93 and 12.08 ± 2.40 mm for the automatic method, observer 1 and observer 2 respectively. The automatic measurement overestimated the MLD slightly in the ilio-femoral artery at the

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

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

    Between 1998 and 2001, mortalities due to verrucous endocarditis were experienced at several mink farms. Gram-positive cocci were isolated from the endocardium of all the animals examined but not always from other internal organs. Almost all the isolates were identified as Streptococcus bovis and...... only a few isolates belonged to other Streptococcus species. Typing by pulsed-field gel electrophoresis of a selection of isolates revealed several patterns and several different clones. Attempts to reproduce disease by the injection of cultures of a field isolate into healthy mink failed....

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

    Background Superantigens are indispensable virulence factors for Staphylococcus aureus in disease causation. Superantigens stimulate massive immune cell activation, leading to toxic shock syndrome (TSS) and contributing to other illnesses. However, superantigens differ in their capacities to induce body-wide effects. For many, their production, at least as tested in vitro, is not high enough to reach the circulation, or the proteins are not efficient in crossing epithelial and endothelial barriers, thus remaining within tissues or localized on mucosal surfaces where they exert only local effects. In this study, we address the role of TSS toxin-1 (TSST-1) and most importantly the enterotoxin gene cluster (egc) in infective endocarditis and sepsis, gaining insights into the body-wide versus local effects of superantigens. Methods We examined S. aureus TSST-1 gene (tstH) and egc deletion strains in the rabbit model of infective endocarditis and sepsis. Importantly, we also assessed the ability of commercial human intravenous immunoglobulin (IVIG) plus vancomycin to alter the course of infective endocarditis and sepsis. Results TSST-1 contributed to infective endocarditis vegetations and lethal sepsis, while superantigens of the egc, a cluster with uncharacterized functions in S. aureus infections, promoted vegetation formation in infective endocarditis. IVIG plus vancomycin prevented lethality and stroke development in infective endocarditis and sepsis. Conclusions Our studies support the local tissue effects of egc superantigens for establishment and progression of infective endocarditis providing evidence for their role in life-threatening illnesses. In contrast, TSST-1 contributes to both infective endocarditis and lethal sepsis. IVIG may be a useful adjunct therapy for infective endocarditis and sepsis. PMID:27124393

    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.

    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.

    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.

    Uncommon microorganisms are increasingly being recognized as causative agents of paediatric infectious endocarditis (IE). We report a 4-year old girl with congenital heart disease, who suffered from 2 IE episodes secondary to Aggregatibacter aphrophilus (formerly Haemophilus aphrophilus) and Staphylococcus lugdunensis, both rarely reported pathogens in this age group. The patient was initially successfully treated with prolonged intravenous antibiotic courses, however removal of the Contegra valved conduit during the second episode was required due to recurrence of fever and development of pulmonary embolism despite completion of antibiotic therapy. A. aphrohilus is a member of the fastidious gram negative microorganisms of the HACEK group (Haemophilus spp., Aggregatibacter spp, Cardiobaterium hominis, Eikenella corrodens and Kingella kingae), that colonize the oropharynx and are a recognised cause of IE. Prognosis of children with IE due to HACEK group members varies, half of them suffering from complications and mortality rates of 10-12.5%. Although S. lugdunensis belongs to coagulase negative staphylococci (CONS), it behaves more like S. aureus species rather than CONS. This microorganism is a well-described cause of endocarditis in adult patients, associated with high requirements of surgical procedures and mortality (42-78%). In conclusion, paediatric IE can be caused by uncommon microorganisms associated with severe complications and potential fatality. The isolation of S. lugdunensis or A. aphrophilus in febrile patients should be considered clinically relevant and cardiac involvement must be ruled out. Those patients with proved IE will require prolonged intravenous antibiotic courses and in complicated cases surgical intervention. PMID:25751682

    Rhizobium radiobacter is a Gram-negative, nitrogen-fixing bacterium, which is found mainly on the ground. It rarely causes infections in humans. It has been associated with bacteremia, secondary to colonization of intravascular catheters, in immunocompromised patients. The aim of this paper was to report the case of an infective endocarditis caused by R. radiobacter, in a 47-year-old male, diagnosed with chronic kidney disease stage 5, on replacement therapy with hemodialysis and who attended the medical center with fever of two weeks duration. The patient was hospitalized and samples of peripheral blood were taken for culture. Empirical antibiotic therapy was started with cefotaxime plus vancomycin. The transthoracic echocardiogram revealed fusiform vegetation on the tricuspid valve, with grade III-IV/IV regurgitation. On the seventh day after the start of antibiotic therapy, the patient had a clinical and paraclinical improvement. The bacterium identified by blood culture was Rhizobium radiobacter, ceftriaxone-resistant and sensitive to imipenem, amikacin, ampicillin and ampicillin/sulbactam. Because of the clinical improvement, it was decided to continue treatment with vancomycin and additionally, with imipenem. At 14 days after the start of antibiotic therapy, the patient was discharged with outpatient treatment with imipenem up to six weeks of treatment. The control echocardiogram showed the absence of vegetation on the tricuspid valve. This case suggests that R. radiobacter can cause endocarditis in patients with intravascular catheters.

    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.

  20. Antibiotic prophylaxis in infective endocarditis: Use or abuse?

    Directory of Open Access Journals (Sweden)

    2012-01-01

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

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

    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.

    2014-02-15

    Acute coronary syndromes in the setting of infective endocarditis may be the result of coronary compression secondary to periannular aortic valve complications, coronary embolism, obstruction of the coronary ostium due to a large vegetation, coronary atherosclerosis, and severe aortic insufficiency. External coronary artery compression as a result of infective endocarditis is a rare and lethal finding with few reported cases available in the medical literature. We present a rare occurrence of an acute coronary syndrome occurring in the setting of a bioprosthetic aortic valve abscess in which there was no complete coronary occlusion visualized and given the patient's recent unremarkable catheterization and findings of diffuse tapering of the proximal left coronary system, the most likely etiology was external compression secondary to the known aortic root abscess, which caused myocardial ischemia, and was confirmed during surgery. Although uncommon, external compression should be considered in the differential diagnosis of acute coronary syndrome in this setting and coronary angiography can be diagnostic of this entity.

    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

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

    Late endocarditis after surgical repair of tetralogy of Fallot is rare. We describe a case of endocarditis following cholecystectomy in a 22-year old patient with repaired tetralogy of Fallot. After cholecystectomy, the patient was referred to a cardiology clinic with unexplained fever and suspicion of endocarditis. Echocardiography revealed a large mass at the basal level of interventricular septum. Endocarditis was diagnosed on the basis of clinical and echocardiographic findings and antibiotic treatment was initiated immediately. Nine days later, the clinical status of the patient deteriorated and urgent surgery was performed. Patch dehiscence which mimicked a large vegetation, and multiple vegetations on the patch were found during operation. The patch was removed and ventricular septum defect was repaired with a new dacron patch. Enterobacter agglomerans was isolated in the vegetation cultures. PMID:15856630

    Reported here is a successfully treated case of native mitral valve endocarditis caused by Staphylococcus lugdunensis and a review of 47 similar cases reported in the English literature. In the literature review, perineal skin flora appeared to be the source of the organism in patients with endocarditis. Staphylococcus lugdunensis is generally susceptible in vitro to beta-lactam agents. If speciation is not performed, these bacteria might be mistaken for Staphylococcus epidermidis, a relatively avirulent bacterium that is a common contaminant of cultures. Prompt speciation can lead to earlier recognition of endocarditis and possibly enable earlier surgical intervention with improved outcome for this high-mortality infection. Multiple positive blood cultures yielding coagulase-negative staphylococci should be identified to the species level; endocarditis or another intravascular source of infection should be sought.

  9. Tricuspid Valve Endocarditis With Group B Streptococcus After an Elective Abortion: The Need for New Data

    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.

    Full Text Available To determine the most informative prognostic signs of infectious endocarditis development in children with heart pathology on the background of bacterial infections clinical course of 15 cases of infective endocarditis in children aged from 1 month to 17 years was performed. The comparison group consisted of 40 children aged 5 - 17 years with mitral valve prolapse. Of 19 analyzed clinical-anamnestic predictive diagnostic features for the development of infective endocarditis in children, presence of febrile fever during infusion therapy, the operated congenital heart disease, treatment in an intensive therapy unit with mechanical ventilation, intravenous infusions through a catheter lasting more than three days, a positive blood culture during the disease course, diagnostic catheterization of large vessels were of high informative value. In a positive prognosis of infective endocarditis development with a probability of 95% and more, children underwent complex of therapeutic measures with the following observation of pediatric cardio-rheumatologist.

    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.

    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.)

    The absence of controlled evidence and the high prevalence of mitral-valve prolapse have created substantial uncertainty about whether this condition is an important risk factor for bacterial endocarditis. We evaluated this risk in a case-control study of hospital inpatients who had undergone echocardiography and who lacked any known cardiovascular risk factors for endocarditis, apart from mitral-valve prolapse and isolated mitral-regurgitant murmurs. Thirteen (25 per cent) of 51 patients with endocarditis had mitral-valve prolapse, as compared with 10 (seven per cent) of the 153 matched controls without endocarditis. For the 51 matched case-control sets, the odds ratio (8.2; 95 per cent confidence interval, 2.4 to 28.4) indicated a substantially higher risk of endocarditis for people with mitral-valve prolapse than for those without it. This association remained statistically significant when parenteral drug abuse and routine antibiotic prophylaxis preceding dental work and other forms of instrumentation were taken into account. Furthermore, the risk may be higher than is indicated by this study, since 46 per cent of the controls underwent echocardiography for clinically suspected mitral-valve prolapse, suggesting an overrepresentation of mitral prolapse in the control group. The results support the contention that mitral-valve prolapse is a significant risk factor for bacterial endocarditis. PMID:7110242

    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.

    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.

    A 59-year-old man was admitted with a 3-month history of daily fevers as well as bilateral knee pain and swelling. Medical history was significant for bilateral knee arthroplasties 4 years prior to admission. Two sets of peripheral blood cultures as well as bilateral knee synovial fluid grew Enterococcus faecalis within 10 hours. Transoesophageal echocardiography revealed aortic and mitral valve vegetations suggestive of infectious endocarditis, with severe regurgitation secondary to large size. The patient's hospitalisation was complicated by acute heart failure, necessitating emergent mitral valve repair and aortic valve replacement, followed shortly thereafter by bilateral total knee arthroplasty resection with placement of antibiotic spacers. He was treated with intravenous penicillin and gentamicin for 4 months and recovered fully. He underwent repeat bilateral knee arthroplasties and was placed on amoxicillin for 6 months postoperatively, with no further evidence of infection. PMID:27207984

  1. Optimizing Guideline-Recommended Antibiotic Doses for Pediatric Infective Endocarditis.

    2016-05-01

    The American Heart Association recently published an updated scientific statement on the management of infective endocarditis in childhood. The recommendations included for vancomycin, aminoglycoside, and β-lactam dosing and monitoring are based primarily on expert opinion and do not consider available evidence for dose optimization based on pharmacokinetic and pharmacodynamic principles in pediatric patients. This is concerning because even when clinically necessary, some practitioners may be hesitant to deviate from guideline-recommended doses. In this perspective, we highlight potential areas for improvement in the statement-recommended doses and summarize evidence supporting antibiotic dosing optimization. The addition of a pediatric clinical pharmacist with expertise in antibiotic dosing to the panel would be beneficial for future updates. PMID:26917819

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

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

  8. Is there a role for Tc-99m HMPAO leucocyte scintigraphy in patients with infective endocarditis?

    International Nuclear Information System (INIS)

    Aim: Infective endocarditis is still an important disease in developing countries. Due to the difficult diagnosis, treatment is often delayed or inappropriate. A combination of clinical findings and echocardiography are used most often, but have a low sensitivity. As Tc-99m HMPAO labelled leucocyte scintigraphy is used routinely to evaluate patients with suspected infectious processes, it was postulated that this technique may also aid in the diagnosis of acute infective endocarditis in patients with rheumatic heart disease. Materials and Methods: Six patients who presented with clinical signs and symptoms of infective endocarditis, were referred for Tc-99m HMPAO labelled leucocyte scintigraphy. The white blood cells were labelled according to standard procedures. Whole body planar imaging, and single photon emission tomography of the chest area, with imaging at 30 minutes, 3 hours and 24 hours after the administration of the labelled leucocytes, were performed on all patients. Results: All the scintigrams were negative. No abnormal concentration of leucocytes could be detected in the region of the heart. This was in spite of clinical findings indicative of active infective endocarditis. Conclusion: Vegetations mainly consist of masses of clotted blood and blood cell debris, containing the causative organisms. Leucocytes do not play a major role in the pathologic process. Although only six patients were studied, it appears that Tc-99m HMPAO leucocyte scintigraphy is of no value in the evaluation of patients with infective endocarditis. A study after the administration of radiolabelled antibiotics may be of greater value and should be considered in these patients

    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.

    Incidence of infective endocarditis during pregnancy is around 0.006% with high maternal and fetal mortality. Bacillus cereus is an extremely rare cause for endocarditis in intravenous drug abusers (IVDA) or those with valvular disease or devices such as pacemakers. We report a case of B. cereus endocarditis, which, to the best of our knowledge, has never been reported in pregnancy. A 30-year-old, 25-week pregnant female presented with right shoulder pain, swelling and erythema on the lateral aspect of deltoid muscle from large abscess over her deltoid muscle. She was found to have a vegetation on the native tricuspid valve. Cultures from abscess fluid and blood cultures grew B. cereus, she was appropriately treated with antimicrobials and had favorable outcomes. There are cereus endocarditis reported but none during pregnancy. When cultures grow unusual organisms the case must be thoroughly investigated. This case illustrates a rare situation (endocarditis in pregnancy) with an unusual outcome (B. cereus) on an uncommon valve (tricuspid valve). PMID:26793477

    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.

  19. 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)

    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

    2004-01-01

    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.

    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 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.

    Full Text Available Brucella endocarditis is a rare condition which occurs as a focal complication in chronic brucellosis cases. We report a rare brucella endocarditis case in a RVHD patient. A 26 years old male was admitted with fever on off for almost one year. The blood culture yielded growth of Brucella melitensis after ten days of incubation. Isolated colonies were reconfirmed as Brucella species by PCR study. Patient’s serum tested positive for brucella slide agglutination test and STAT titer was 640IU. Echocardiography showed vegetation on mitral valve. Patient was treated with both medical and surgical intervention. After chemotherapy, patient’s blood culture was sterile, slide agglutination & STAT (40IU were negative. Repeat echocardiography showed no fresh vegetation. Considering high mortality rate (80% in Brucella endocarditis, it is very important for clinicians to suspect it. Prompt antibiotic therapy and surgical intervention is life saving in fatal cases.

    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.

    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

    . 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......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%). A...... 10 cases of endocarditis due to S. suis and E. rhusiopathiae were disclosed. Within lesions, streptococci predominated (53%) followed by E. rhusiopathiae (30%).

  18. Surgical management for active infective endocarditis: a single hospital 10 years experience

    International Nuclear Information System (INIS)

    To examine the outcome of surgery for active infective endocarditis (IE) in a cohort of patients. One hundred sixty-four consecutive patients who underwent valve surgery for active IE (diagnosis according to Duke criteria) in Madani Heart Center, Tabriz, Iran from 1996 to 2006 were studied. The mean age of patients was 36.3+-16 years overall: 34.6+-17.5 years for native valve endocarditis and 38.6+-15.2 yrs for prosthetic valve endocarditis (p=0.169). Ninety one (55.5%) patients were men. The infected valve was native in 112 (68.7%) of patients and prosthetic in 52(31.3%). In 61 (37%) patients, no predisposing heart disease was found. The aortic valve was infected in 78 (47.6%), mitral valve in 69 (42.1%), and multiple valves in 17 (10.3%) of patients. Active culture positive endocarditis was present in 81 (49.4%) whereas 83 (50.6%) patients had culture-negative endocarditis. Staphylococcus aureus was the most common isolated microorganism. Ninety patients (54.8%) were in NYHA classes III and IV. Mechanical valves were implanted in 69 patients (42.1%) and bioprostheses in 95 (57.9%), including a homograft in 19 (11.5%). There were 16 (9%) operative deaths, but there was only 1 death in patients that underwent aortic homograft replacement. Reoperation was required in 18 (10.9%) of cases. On multivariate logistic regression analysis, Staphylococcus aureus infection (p=0.008), prosthetic valve endocarditis (p=0.01), paravalvular abscess (p=0.001) and left ventricular ejection fraction less than 40% (p=0.04) were independent predictors of in-hospital mortality. Surgery for infective endocarditis continues to be challenging and associated with high operative mortality and morbidity. Prosthetic valve endocarditis, impaired ventricular function, paravalvular abscess and Staphylococcus aureus infection adversely affect in-hospital mortality. Also we found that aortic valve replacement with an aortic homograft can be performed with acceptable in hospital mortality and

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

OBJETIVO: Relatar o caso de um paciente masculino, tabagista, com um nódulo pulmonar direito com características de malignidade, detectado em radiografia de tórax de rotina, cujo diagnóstico anatomopatológico foi de schwannoma benigno de nervo intercostal. MÉTODOS: Revisaram-se os dados referentes ao quadro clínico, exames laboratoriais e de imagem (radiografia e tomografia computadorizada de tórax do caso em estudo, assim como os exames anatomopatológico e imuno-histoquímico do espécime cirúrgico. RESULTADOS: O paciente foi submetido à toracotomia direita diagnóstica com ressecção da tumoração. O exame anatomopatológico convencional mostrou células tumorais de aspecto fusiforme, dispostas em paliçada, formando os corpos de Verocay, compatível com schwannoma intercostal. A imuno-histoquímica foi positiva para proteína S-100, vimentina e enolase, e negativa para neurofilamentos. CONCLUSÃO: O diagnóstico definitivo de schwannoma só é possível por meio da análise histopatológica e imuno-histoquímica da lesão. Seu aspecto celular, associado à atividade mitótica e a áreas de pleomorfismo, pode levar ao diagnóstico incorreto de malignidade. A imuno-histoquímica, por meio da proteína S-100, é útil na caracterização da benignidade da lesão, já que não é detectada nas lesões malignas.

    2016-01-01

    Full Text Available Background. Infective endocarditis is associated with considerable morbidity and mortality. Guidelines addressing prophylaxis and management of infective endocarditis do not extensively deal with concomitant pregnancy, and case reports on infective endocarditis are scarce. This is the first published report of infective endocarditis by Staphylococcus lugdunensis in a pregnant woman. Case Presentation. We report a single case of a 35-year-old woman in her 24th week of pregnancy who was admitted to our intensive care unit with fever and suspected infectious endocarditis. Blood culture detected Staphylococcus lugdunensis. A vegetation and severe mitral regurgitation due to complete destruction of the valve confirmed the diagnosis. An interdisciplinary panel of cardiologists, maternal-fetal medicine specialists, cardiac and plastic surgeons, infectiologists, anesthesiologists, and neonatologists was formed to determine the best therapeutic strategy. Conclusions. Timing and indications for surgical intervention to prevent embolic complications in infective endocarditis remain controversial. This original case report illustrates how managing infective endocarditis by Staphylococcus lugdunensis particularly in the 24th week of pregnancy can represent a therapeutic challenge to a broad section of specialties across medicine. Critical cases like this require a thorough weighing of risks and benefits followed by swift action to protect the mother and her unborn child.

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 O diagnóstico do tromboembolismo pulmonar agudo é baseado na probabilidade clínica, uso do dímero D (quando disponível e na avaliação por imagem. Os principais métodos de imagem utilizados no diagnóstico são representados por cintilografia ventilação-perfusão, angiografia pulmonar e tomografia computadorizada (TC. Na última década vários estudos têm demonstrado que a TC espiral apresenta elevada sensibilidade e especificidade no diagnóstico de tromboembolismo pulmonar agudo. Uma melhor avaliação das artérias pulmonares tornou-se possível com a recente introdução dos equipamentos de TC espirais com multidetectores. Vários pesquisadores têm sugerido que a angiografia pulmonar por TC espiral deve substituir a cintilografia na avaliação de pacientes com suspeita clinica de tromboembolismo pulmonar agudo. Os autores discutem os principais métodos de imagem utilizados no diagnóstico de tromboembolismo pulmonar agudo enfatizando o papel da TC espiral.The diagnosis of acute pulmonary thromboembolism is based on the clinical probability, use of D-dimer (when available and imaging. The main imaging modalities used in the diagnosis are ventilation-perfusion (V/Q, scintigraphy, angiography, and computed tomography (CT. In the last decade several studies have demonstrated that spiral CT has a high sensitivity and specificity in the diagnosis of acute pulmonary thromboembolism. The evaluation of the pulmonary arteries has further improved with the recent introduction of multidetector spiral CT scanners. Various investigators have suggested that spiral CT pulmonary angiography should replace scintigraphy in the assessment of patients whose symptoms are suggestive of acute PE. This article discusses the role of the various imaging modalities in the diagnosis of acute pulmonary thromboembolism with emphasis on the role of spiral CT.

    Bartonella spp. are fastidious bacteria that cause blood culture-negative endocarditis and have been increasingly reported. In this study, we included all patients retrospectively and prospectively diagnosed with Bartonella endocarditis in our French reference center between 2005 and 2013. Our diagnosis was based on the modified Duke criteria and microbiological findings, including serological and PCR results. To review the published literature, we searched all human Bartonella endocarditis cases published in the PubMed database between January 2005 and October 2013. We report here a large series of 106 cases, which include 59 cases that had not previously been reported or mentioned. Indirect immunofluorescence assays, Western blotting, and real-time PCR from total blood, serum, and valve tissue exhibited sensitivities of 58%, 100%, 33%, 36%, and 91%, respectively. The number of cases reported in the literature between 2005 and 2013 increased to reach a cumulative number of 196 cases. The number of cases reported in the literature by other centers is increasing more rapidly than that reported by our French reference center (P immunofluorescence assay, or a positive Western blot assay be considered major Duke criteria for Bartonella endocarditis. There is no real increase in the incidence of these infections but rather a better understanding and interest in the disease resulting from the improvement of diagnostic tools. PMID:25540398

    The Gerbode's defect is a communication between the left ventricle and right atrium. It is usually congenital, but rarely is acquired, as a complication of endocarditis, myocardial infarction, trauma, or after previous cardiac surgery. The acquired Gerbode defect with involvement of the tricuspid valve acquired after bacterial endocarditis can be challenging to repair. We present a rare case of young woman, with endocarditis of the tricuspid valve and acquired Gerbode defect without previous cardiac surgery. She underwent successful surgical closure of the Gerbode defect and reconstruction of the septal leaflet of the tricuspid valve using a an autologous pericardial patch. A total of 20 other cases were reported with acquired Gerbode defect due to endocarditis in patients without previous cardiac surgery. Three other cases presented acquired Gerbode defect due to myocardial infarction and two due to chest trauma. Another series of 62 patients presented acquired Gerbode defect after previous cardiac surgery. Surgical treatment is always feasible with excellent outcome. However the percutanous transcatheter closure remains an excellent option especially in high risk patients. PMID:26353810

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available Despite diagnostic and therapeutic advances in medical, surgical, and critical care, the mortality rate for Aspergillus endocarditis remains dismal (approaching 100%. We report a case of a 49 year old immunocompetent woman with recent aortic valve prosthesis who presents with fever, chills, sweats, left facial droop, left arm weakness, petechial rash and cyanotic toes. Initial trans-esophageal echo was normal but a repeat study revealed a 9 × 5 mm vegetation abutting the aortic pros- thesis. Microbiological correlation could not be documented despite the presence of persistent fever through serial blood cultures, and the diagnosis of Aspergillus fumigatus endocarditis was ultimately made on embolectomy specimen when she developed an ischemic right leg. Aggressive medical treatment was initiated with intravenous voraconazole, liposomal amphotericin-B and heparin. The timing of surgical intervention was contemplated, but was precluded by multiple comorbidities. She succumbed to her illness after developing cerebral herniation following intraparenchymal hemorrhage.The effectiveness of combined medical intervention and surgical valve replacement for Aspergillus endocarditis is therefore contingent on high diagnostic suspicion and early echocardiographic detection in a high risk individual with features of culture-negative endocarditis.

    2016-06-01

    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

    2013-11-26

    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.

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

    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. The low number of viable donors continues to be a major obstacle to increasing the number of lung transplants, resulting in high mortality among patients on the waiting list.

    Use of cardiovascular implantable electronic devices (CIED), including permanent pacemakers (PPM) and implantable cardioverter defibrillators (ICD), has increased dramatically over the past two decades. Most CIED infections are caused by staphylococci. Fungal causes are rare and their prognosis is poor. To our knowledge, there has not been a previously reported case of multifocal Candida endocarditis involving both a native left-sided heart valve and a CIED lead. Here, we report the case of a 70-year-old patient who presented with nausea, vomiting, and generalised fatigue, and was found to have Candida glabrata endocarditis involving both a native aortic valve and right atrial ICD lead. We review the literature and summarise four additional cases of CIED-associated Candida endocarditis published from 2009 to 2014, updating a previously published review of cases prior to 2009. We additionally review treatment guidelines and discuss management of CIED-associated Candida endocarditis. PMID:26403965

    Full Text Available Abstract Introduction Polymicrobial endocarditis is a well-recognized problem in intravenous drug users and it accounts for 1 to 3% of endocarditis cases overall and up to 9% in other series. The most common combinations of organisms include Staphylococcus aureus and Streptococcus pneumoniae followed by Staphylococcus aureus and Pseudomonas aeruginosa. Candida parapsilosis endocarditis carries a mortality rate of 45%, and each infection with Candida or Pseudomonas endocarditis per se carries a very high mortality rate approaching 85% and 80%, respectively. The combination of P. aeruginosa and C. parapsilosis has never been encountered and there have been no earlier reports of the combination of C. parapsilosis and P. aeruginosa in adult intravenous drug users as a cause of endocarditis. Case presentation We present a 49-year-old man with bivalvular endocarditis with P. aeruginosa and C. parapsilosis. He had a prior bivalvular replacement in 2005 that became infected with the above microorganisms and he was treated with intravenous antibiotics. Because of ongoing intravenous drug use, a second valve replacement was denied. A few days later, the patient presented with septic shock secondary to P. aeruginosa and C. parapsilosis recurrent endocarditis. The infection was cured with a second bivalvular replacement and extended therapy with antibiotics and antifungals. Conclusion This is the first time a patient has presented with P. aeruginosa and C. parapsilosis endocarditis. Relapsing polymicrobial endocarditis can be cured with medical and surgical therapy.

    Streptococcus bovis is found as a commensal organism in human gut and may become opportunistically pathogenic. Infective endocarditis is one of the commonest modes of presentation of this infection. The association between Streptococcus bovis endocarditis and colorectal cancer is well recognized. We report a case of Streptococcus bovis endocarditis along with a refractory iron deficiency anaemia associated with concomitant carcinoma of ascending colon in a 63-year-old male. Cooccurrence of these two conditions may cause a challenge in the management. Considering the strong association of colon cancer with Streptococcus bovis endocarditis, a detailed screening colonoscopy is mandatory following the diagnosis of the latter. PMID:26881154

Fusion image road-mapping was performed using angiographic phase CT images or MR images acquired before and intra-procedural unenhanced cone-beam CT. Radiation dose of the procedure, volume of intra-procedural iodinated contrast medium, fluoroscopy time, and overall procedural time were recorded. Reasons for potential fusion imaging inaccuracies were also evaluated.ResultsImage co-registration and fusion guidance were feasible in all procedures. Mean radiation dose of the procedure was 60.21 Gycm2 (range 55.02–63.75 Gycm2). The mean total procedure time was 32.2 min (range 27–38 min). The mean fluoroscopy time was 12 min and 3 s. The mean procedural iodinated contrast material dose was 24 mL (range 20–40 mL).ConclusionsIF gives Interventional Radiologists the opportunity to use new technologies in order to improve outcomes with a significant reduction of contrast media administration.

    Full Text Available 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. Chronic obstructive pulmonary disease is a clinical risk factor for pulmonary thromboembolism. The presentation of acute pulmonary thromboembolism and acute exacerbation of chronic obstructive pulmonary disease often mimic each other so closely that they cannot be distinguished clinically. The structural abnormalities of the lungs in chronic obstructive pulmonary disease make also difficult to interpret the results of noninvasive tests like ventilation-perfusion lung scans. Therefore, diagnosing acute pulmonary thromboembolism in patients with underlying

    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

    2015-01-01

    Full Text Available Scopulariopsis is a genus of mold that is usually associated with onychomycosis and rarely causes complicated infection in immunocompetent persons. We describe a case of an immunocompetent 65-year-old male with a history of mitral valve repair with prosthetic ring placement who developed acute left posterior knee pain. Imaging showed a left popliteal artery aneurysm and thrombus, and further evaluation with transesophageal echocardiogram demonstrated two large, mobile mitral valve vegetations. He underwent debridement and replacement of the mitral valve, followed by debridement of the left popliteal artery with peroneal artery bypass. The intraoperative cultures grew Scopulariopsis brevicaulis. Due to the resistant nature of the organism, he was initially treated with combination antifungals including liposomal amphotericin B, caspofungin, and voriconazole and was continued on chronic suppression with posaconazole with no evidence of recurrence. Scopulariopsis is a rare cause of fungal endocarditis. Treatment of Scopulariopsis endocarditis is challenging and is not well understood due to its rarity.

    @@ 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.

    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.

    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 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

    An adult, wild-collected, male harp seal (Phoca groenlandica) was transferred from a rehabilitation center to a display facility because of unilateral phthisis bulbi and decreased use of the right forelimb, which precluded its release. In quarantine, the animal demonstrated limited use of the right forelimb, which acutely progressed to complete disuse of the limb accompanied by intermittent lethargy. One month after transfer, the animal was found dead on exhibit. Necropsy showed septic arthritis of the right scapulohumeral joint, valvular endocarditis with systemic bacterial thromboembolism, and infarction of the cerebrum and myocardium. Culture of the blood and affected joint space revealed Staphylococcus aureus. Bacterial polymerase chain reaction of formalin-fixed tissues from the heart and brain were also positive for S. aureus. Staphylococcus aureus infection should be considered as an additional cause of endocarditis and embolic encephalitis in seals. PMID:19569495

    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.

Echocardiographic examination revealed a large vegetative lesion on the right atrioventricular valve with valvular insufficiency, a mildly dilated right atrium, and pulmonary hypertension. Postmortem examination confirmed the presence of pneumonia and bacterial endocarditis with dystrophic mineralization of the right atrioventricular valve, associated with different bacteria than those cultured from the tracheal wash. The present case is the first report of endocarditis in a boa constrictor and contributes to the rare reports of cardiac disease in snakes. PMID:25831585

    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 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.

  7. Radiolabeled antibody in the detection of infection using endocarditis as a model

    International Nuclear Information System (INIS)

    The authors have examined a method to detect infections using radiolabeled antibodies. Staphylococcal endocarditis was chosen as a model because it poses a common clinical diagnostic problem. The experiments demonstrate that biologically active antibodies may be extracted and efficiently labeled by a relatively simple process. This has the potential to make the specificity of the in vivo antigen-antibody reaction available through the use of autologously extracted, labeled γ-globulin

    The epidemiology, and clinical and microbiological spectrum, of infective endocarditis (IE) in Greece was analysed in a prospective 4-year study in a tertiary hospital and a heart surgery centre in Athens. In total, 101 cases of IE (71 men, 30 women, aged 54.4 +/- 17.1 years) were studied, with a follow-up period of 3 months. Seventy-seven cases were definite and 24 possible; 59 involved native valves (native valve endocarditis; NVE), 31 prosthetic valves (prosthetic valve endocarditis; PVE), of which nine were early and 22 late, and 11 permanent pacemakers (pacemaker endocarditis; PME). There was a predominant involvement of aortic (48/101) and mitral (40/101) valves. Seven patients had rheumatic valvular disease, two had mitral valve prolapse, and eight had a previous history of IE. Thirteen and six patients had undergone dental and endoscopic procedures, respectively. In 13 patients, intravenous catheters were used within the 3 months before diagnosis of IE. There were three intravenous drug users among the patients. Staphylococcus aureus was the most important pathogen, isolated in 22% of cases, followed by viridans streptococci (19%) and coagulase-negative staphylococci (16%). Enterococcus spp. were responsible for 3%, HACEK group for 2%, and fungi for 6% of cases. Viridans streptococci were the leading cause of NVE (29%), Staphylococcus epidermidis of PVE (16%), and S. aureus of PME (54.5%). Six of 22 S. aureus and ten of 16 S. epidermidis isolates were methicillin-resistant. Surgical intervention, including total pacemaker removal, was performed in 51.5% of patients. Overall mortality was 16%, but was 29% with PVE, and was significantly higher with medical than with combined surgical and medical therapy (24.5% vs. 8%). Compared with previous studies, there were changing trends in the epidemiology, microbiology, treatment and prognosis of IE in Greece. PMID:15191385

    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...

    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. PMID:26017665

    1988-01-01

    During the period 1973-1984, 72 patients with infective endocarditis (IE) were hospitalized in the medical department, Bergen University Hospital. The male/female ratio was 1.25/1, the mean age 55.3 years. 35 infections were caused by streptococci, 18 by staphylococci, 6 by other microorganisms and in 13 cases no causal organism was found. Only 13 patients had rheumatic heart disease. The overall mortality was 35%, and the mean age of the patients who died was 65 years. The case fatality rates for staphylococcal and streptococcal endocarditis were 61 and 24% respectively. In the period 1973-1978 the case fatality rate was 50% compared to 26% during 1979-1984. The proportion of patients with culture-negative endocarditis was reduced from 31 to 11% from the first to the second half of the study and the percentage of patients who received antibiotics before diagnosis decreased from 81 to 58%. Valve replacement was performed in 4 patients with staphylococcal and 15 with streptococcal infections. Seven cases (mean age 73.4 years) were diagnosed at necropsy; 3 with staphylococcal infections. With increased clinical awareness of IE, liberal use of blood cultures, better diagnostic tools and earlier surgical intervention, especially in staphylococcal infections, a further reduction in mortality should be possible.

    Prosthetic heart valve (PHV) dysfunction remains difficult to recognise correctly by two-dimensional (2D) transthoracic and transoesophageal echocardiography (TTE/TEE). ECG-triggered multidetector-row computed tomography (MDCT), 18-fluorine-fluorodesoxyglucose positron emission tomography including low-dose CT (FDG-PET) and three-dimensional transoesophageal echocardiography (3D-TEE) may have additional value. This paper reviews the role of these novel imaging tools in the field of PHV obstruction and endocarditis.For acquired PHV obstruction, MDCT is of additional value in mechanical PHVs to differentiate pannus from thrombus as well as to dynamically study leaflet motion and opening/closing angles. For biological PHV obstruction, additional imaging is not beneficial as it does not change patient management. When performed on top of 2D-TTE/TEE, MDCT has additional value for the detection of both vegetations and pseudoaneurysms/abscesses in PHV endocarditis. FDG-PET has no complementary value for the detection of vegetations; however, it appears more sensitive in the early detection of pseudoaneurysms/abscesses. Furthermore, FDG-PET enables the detection of metastatic and primary extra-cardiac infections. Evidence for the additional value of 3D-TEE is scarce.As clinical implications are major, clinicians should have a low threshold to perform additional MDCT in acquired mechanical PHV obstruction. For suspected PHV endocarditis, both FDG-PET and MDCT have complementary value. PMID:26744343

The white-blood cell count was 11,000/mm3, the platelet count was 135,000/mm3 and C-reactive protein (CRP 13 mg/dL. Chest X-rays showed right infiltrates. Ceftriaxone was started. Defervescence was rapid, but CRP was still 12 mg/dL after 6 days. A trans-thoracic ecochacardiogram (TTE incidentally showed a liver hypoechoic lesion. A computed tomography scan revealed bilateral cavitated lung nodules and a large liver abscess. Klebsiella pneumoniae was isolated in blood cultures and TTE showed ICD endocarditis and a patent foramen ovalis. Levofloxacin and imipenem/cilastatin were started. The liver abscess was drained. After 30 days, the ICD was removed and re-implanted. At discharge, blood tests were within the normal range and the patient was asymptomatic. Follow up showed improvement of lung and hepatic lesions. To our knowledge, this is the second reported case of K. pneumoniae infective endocarditis with multiple septic emboli. Endocarditis should be suspected in presence of fever after the device implantation, in particular if risk factors are present.

    Streptococcus sanguinis is an important cause of infective endocarditis. Previous studies have identified lipoproteins as virulence determinants in other streptococcal species. Using a bioinformatic approach, we identified 52 putative lipoprotein genes in S. sanguinis strain SK36 as well as genes encoding the lipoprotein-processing enzymes prolipoprotein diacylglyceryl transferase (lgt) and signal peptidase II (lspA). We employed a directed signature-tagged mutagenesis approach to systematically disrupt these genes and screen each mutant for the loss of virulence in an animal model of endocarditis. All mutants were viable. In competitive index assays, mutation of a putative phosphate transporter reduced in vivo competitiveness by 14-fold but also reduced in vitro viability by more than 20-fold. Mutations in lgt, lspA, or an uncharacterized lipoprotein gene reduced competitiveness by two- to threefold in the animal model and in broth culture. Mutation of ssaB, encoding a putative metal transporter, produced a similar effect in culture but reduced in vivo competiveness by >1,000-fold. [(3)H]palmitate labeling and Western blot analysis confirmed that the lgt mutant failed to acylate lipoproteins, that the lspA mutant had a general defect in lipoprotein cleavage, and that SsaB was processed differently in both mutants. These results indicate that the loss of a single lipoprotein, SsaB, dramatically reduces endocarditis virulence, whereas the loss of most other lipoproteins or of normal lipoprotein processing has no more than a minor effect on virulence.

    Oritavancin is a novel lipoglycopeptide with activity against Gram-positive organisms including streptococci, methicillin-resistant Staphylococcus aureus, vancomycin-resistant S aureus (VRSA), and vancomycin-resistant enterococci (VRE) [1-3]. The US Food and Drug Administration approved oritavancin as a single intravenous dose of 1200 mg for the treatment of acute bacterial skin and skin structure infections on the basis of 2 clinical trials demonstrating noninferiority compared with vancomycin [4, 5]. There are limited options for treatment of serious VRE infections. Monotherapy with daptomycin or tigecycline or linezolid may be sufficient in some cases, but combination therapy is often indicated for severe or complicated infections such as endocarditis. Several antibiotic combinations have been used in isolated case reports with some efficacy, including the following: high-dose ampicillin with an aminoglycoside [6], ampicillin with ceftriaxone or imipenem [7, 8], high-dose daptomycin with ampicillin and gentamicin [9] or with gentamicin and rifampin [10], daptomycin with tigecycline [11, 12], quinupristin-dalfopristin with high-dose ampicillin [13] or doxycycline and rifampin [14], and linezolid with tigecycline [15]. The limited efficacy, limited susceptibility, and extensive toxicities with many of these agents and combinations present barriers to effective treatment. Additional treatment options for VRE endocarditis would be valuable. Although oritavancin has been shown to have in vitro activity against some isolates of VRE, clinical data are lacking. We describe the first use of a prolonged course of oritavancin in the treatment of a serious VRE infection, prosthetic valve endocarditis. PMID:26677455

  17. Haemophilus parainfluenzae Mural Endocarditis: Case Report and Review of the Literature

    Full Text Available Haemophilus parainfluenzae, which uncommonly causes endocarditis, has never been documented to cause mural involvement. A 62-year-old immunocompetent female without predisposing risk factors for endocarditis except for poor dentition presented with fever, emesis, and dysmetria. Echocardiography found a mass attached to the left ventricular wall with finger-like projections. Computed tomography showed evidence of embolic phenomena to the brain, kidneys, spleen, and colon. Cardiac MRI revealed involvement of the chordae tendineae of the anterior papillary muscles. Blood cultures grew Haemophilus parainfluenzae. The patient was treated successfully with ceftriaxone with resolution of symptoms, including neurologic deficits. After eleven days of antibiotics a worsening holosystolic murmur was discovered. Worsening mitral regurgitation on echocardiography was only found three weeks later. Nine weeks after presentation, intraoperative evaluation revealed chord rupture but no residual vegetation and mitral repair was performed. Four weeks after surgery, the patient was back to her baseline. This case illustrates the ability of Haemophilus parainfluenzae to form large mural vegetations with high propensity of embolization in otherwise normal cardiac tissue among patients with dental risk factors. It also underscores the importance of physical examination in establishing a diagnosis of endocarditis and monitoring for progression of disease.

    Full Text Available This article describes chronic bacterial endocarditis as the cause of aortic regurgitation in a 25-year-old Thoroughbred used for horseback riding. The horse presented signs of depression, exercise intolerance, and weight loss. A pandiastolic murmur was identified, but no other clinical signs of bacterial endocarditis were identified. Haematological, serum biochemical, and urine analyses did not show any particular abnormalities. Electrocardiography showed a physiological dysrhythmia that was not pertinent to this case. Echocardiography revealed left ventricle (LV dilatation and a nodule in the left coronary cusp of the aortic valve associated with regurgitation. Based on the prevalence of aortic valve pathology in geriatric horses, a noninfectious condition with a myxomatous noninflammatory infiltrate was suspected; therefore, no special treatment was prescribed due to the absence of heart failure. Several months later, the animal was euthanised after experiencing a femur fracture. At necropsy, the horse showed an eccentric left ventricle hypertrophy and 2 nodules in the left coronary cusp of the aortic valve. Histological examination revealed the presence of bacteria, which led to the diagnosis of chronic bacterial 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.

    Full Text Available The HACEK organisms (Haemophilus species, Aggregatibacter species, Cardiobacterium hominis, Eikenella corrodens, and Kingella species are rare causes of infective endocarditis (IE. The objective of this study is to describe the clinical characteristics and outcomes of patients with HACEK endocarditis (HE in a large multi-national cohort. Patients hospitalized with definite or possible infective endocarditis by the International Collaboration on Endocarditis Prospective Cohort Study in 64 hospitals from 28 countries were included and characteristics of HE patients compared with IE due to other pathogens. Of 5591 patients enrolled, 77 (1.4% had HE. HE was associated with a younger age (47 vs. 61 years; p<0.001, a higher prevalence of immunologic/vascular manifestations (32% vs. 20%; p<0.008 and stroke (25% vs. 17% p = 0.05 but a lower prevalence of congestive heart failure (15% vs. 30%; p = 0.004, death in-hospital (4% vs. 18%; p = 0.001 or after 1 year follow-up (6% vs. 20%; p = 0.01 than IE due to other pathogens (n = 5514. On multivariable analysis, stroke was associated with mitral valve vegetations (OR 3.60; CI 1.34-9.65; p<0.01 and younger age (OR 0.62; CI 0.49-0.90; p<0.01. The overall outcome of HE was excellent with the in-hospital mortality (4% significantly better than for non-HE (18%; p<0.001. Prosthetic valve endocarditis was more common in HE (35% than non-HE (24%. The outcome of prosthetic valve and native valve HE was excellent whether treated medically or with surgery. Current treatment is very successful for the management of both native valve prosthetic valve HE but further studies are needed to determine why HE has a predilection for younger people and to cause stroke. The small number of patients and observational design limit inferences on treatment strategies. Self selection of study sites limits epidemiological inferences.

    Full Text Available Abstract Background Endocarditis is a common complication in Staphylococcus aureus bacteremia (SAB. We compared risk factors, clinical manifestations, and outcome in a large, prospective cohort of patients with S. aureus endocarditis in injection drug users (IDUs and in nonaddicts. Methods Four hundred and thirty consecutive adult patients with SAB were prospectively followed up for 3 months. Definite or possible endocarditis by modified Duke criteria was found in 74 patients: 20 patients were IDUs and 54 nonaddicts. Results Endocarditis was more common in SAB among drug abusers (46% than in nonaddicts (14% (odds ratio [OR], 5.12; 95% confidence interval [CI], 2.65–9.91; P P P P = 0.03, and their SAB was more often community-acquired (95% vs 39%, P P P = 0.70. Arterial thromboembolic events and severe sepsis were also equally common in both groups. There was no difference in mortality between the groups at 7 days, but at 3 months it was lower among IDUs (10% compared with nonaddicts (39% (OR, 5.73; 95% CI, 1.20–27.25; P = 0.02. Conclusion S. aureus endocarditis in IDUs was associated with as high complication rates including extracardiac deep infections, thromboembolic events, or severe sepsis as in nonaddicts. Injection drug abuse in accordance with younger age and lack of underlying diseases were associated with lower mortality, but after adjusting by age and underlying diseases injection drug abuse was not significantly associated with mortality.

    Full Text Available Asma y enfermedad pulmonar obstructiva crónica (EPOC son enfermedades pulmonares comunes con semejanzas y diferencias. Estudios genéticos recientes han dado información importante acerca de los múltiples loci susceptibles para cada enfermedad. Estudios del genoma han mostrado resultados similares en al menos una región cromosomal en ambas enfermedades, así como también evidencia de la interacción con factores ambientales (por ejemplo, el fumado activo en los pacientes con EPOC, o el pasivo en aquellos con asma. Existen pocos estudios recientes acerca del remodelamiento de la vía aérea y su importancia en pacientes asmáticos persistentes crónicos, lo que podría explicar de cierta forma la progresión de estas personas a enfermedades pulmonares obstructivas crónicas.

    Group B streptococcal (GBS) tricuspid infective endocarditis is a very rare clinical entity. It affects intravenous drug users, pregnant, postpartum women, and the elderly. We report the case of a 68-year-old patient without known predisposing factors who presented a GBS tricuspid endocarditis treated by penicillin and aminoglycosides with no response. The patient was operated with a good evolution. Our case is the 25th reported in the literature. GBS disease is increasing in the elderly and is mainly associated to comorbid conditions. Tricuspid infective endocarditis with Group B streptococcus predominantly presents as a persistent fever with respiratory symptoms due to pulmonary embolism. Therefore, it requires a medicosurgical treatment and close follow-up. PMID:27053903

    Full Text Available Abstract Introduction Distal arterial embolisation and subsequent aneurysm formation are rare occurrences and most are secondary to trauma. We have found no case reports that describe posterior tibial aneurysm formation secondary to bacterial endocarditis. Case presentation We report the case of a 47-year-old Caucasian man who, 2 years after an episode of subacute bacterial endocarditis, presented with signs and symptoms consistent with posterior tibial aneurysm formation. Conclusion Posterior tibial aneurysm formation is a rare occurrence, most commonly occurring after trauma and, although other causes have been described, to our knowledge, endocarditis has not been implicated before, and as such should therefore be borne in mind when dealing with cases where no obvious aetiology is evident.

    Full Text Available Objetivo: Com a finalidade de estabelecer uma linha de pesquisa em cirurgia redutora de volume pulmonar, foi proposta a reprodução de um modelo experimental de enfisema em ratos através da instilação intratraqueal de papaína. Métodos: Foi feita a instilação orotraqueal de papaína (20mg/kg dissolvida em 3,5ml/kg de solução fisiológica a 0,9%. Após 40 dias da instilação, os animais foram submetidos a mecânica ventilatória, com medidas de elastância e resistência do sistema respiratório, e sacrificados com retirada dos pulmões. O tecido pulmonar dos animais foi analisado qualitativamente com coloração de hematoxilina-eosina e submetido à análise morfométrica com medida do diâmetro alveolar médio. O tecido pulmonar foi também submetido à coloração de resorcina-fucsina, para identificação de fibras elásticas, que foram quantificadas em septos alveolares através de análise digital de imagem. Resultados: A análise histológica dos pulmões dos animais submetidos à instilação de papaína mostrou um enfisema pan-acinar, com rotura de septos alveolares e hiperdistensão alveolar. A análise morfométrica revelou médias superiores de diâmetro alveolar médio nos pulmões dos animais submetidos à papaína (149,08mim e 100,56mim, em comparação com o grupo de solução fisiológica (64,08mim e 75,90mim. A quantificação de fibras elásticas de septos alveolares de animais tratados com papaína foi 70% menor do que a de animais submetidos à solução fisiológica. A mecânica ventilatória não mostrou diferença na resistência do sistema respiratório de animais submetidos à papaína ou à solução fisiológica. Já no caso da elastância do sistema respiratório, esta foi menor nos animais do grupo com papaína, em comparação com o grupo com solução fisiológica, demonstrando comportamento funcional do grupo com papaína compatível com enfisema pulmonar, apresentando diminuição da capacidade de

    Full Text Available Las enfermedades relacionadas al amianto se producen por la inhalación de fibras de asbestos en su variedad crisotilo o amianto blanco. A pesar de que en la Argentina la prohibición data del año 2003, existen numerosas industrias donde se sigue trabajando con este mineral, entre ellas las metalúrgicas y acerías. Actualmente se conoce la alta patogenicidad de este material, por lo que en muchos países existen programas de seguimiento de los trabajadores expuestos. Se describen las características generales y manifestaciones clínicas pulmonares de 27 pacientes que trabajaron en una gran acería de América del Sur. El diagnóstico de amiantopatías se realizó mediante historia clínica laboral, antecedente de exposición al amianto, estudios complementarios de función pulmonar e imágenes del tórax. Se analizaron la fuente de exposición (laboral, doméstica y ambiental, tiempo de exposición y período de latencia en los pacientes de los cuales se detectó enfermedad relacionada. Los antecedentes de tabaquismo fueron tenidos en cuenta para el análisis. En 22 pacientes se presentaron patologías benignas (81.4%, 16 de ellos tenían lesiones exclusivamente pleurales y otros 6 asbestosis. Las patologías malignas se presentaron en 5 pacientes (18.5%, en 4 fueron mesoteliomas y en uno carcinoma pulmonar. El problema de la exposición al amianto tiene vigencia actual. De ahí la necesidad de un programa de vigilancia en trabajadores expuestos al amianto actualmente o en el pasado, para detectar, notificar, registrar e investigar las características de estas patologías.

    Full Text Available La hipertensión arterial pulmonar primaria (HAPP es una enfermedad crónica de causa desconocida que se caracteriza por un incremento de la presión sanguínea media en la arteria pulmonar, mayor de 25 mmHg en reposo o más de 30 mmHg durante el ejercicio. Es una enfermedad que afecta a ambos sexos y no tiene predilección racial. La HAPP sin tratar puede conducir a una insuficiencia ventricular derecha y por consiguiente, a la muerte. La HAPP involucra varios mecanismos subyacentes, dentro de los cuales la vasoconstricción, el remodelado vascular y la trombosis in situ son los más importantes. Aunque hasta el presente la HAPP no tiene cura, se ha logrado mejorar la calidad de vida de los pacientes utilizando diversas estrategias terapéuticas, tanto farmacológicas como quirúrgicas. Por tanto, el conocimiento de los factores que predisponen al desarrollo de la HAPP, así como la búsqueda de alternativas para su tratamiento o una cura definitiva es de interés actual. El presente trabajo describe brevemente las características de la HAPP incluyendo datos de la epidemiología, fisiopatología, manifestaciones clínicas, causas y factores de riesgo. Además, describe las principales terapias farmacológicas empleadas en los pacientes con HAPP, así como algunos modelos experimentales que permiten evaluar nuevos fármacos potencialmente efectivos para tratar la hipertensión arterial pulmonar primaria.

    Full Text Available Patients with scleroderma are at increased risk for the development of pulmonary hypertension, and the development of unexplained dyspnea or an isolated decrease in diffusing capacity should prompt evaluation. Echocardiography is often helpful in this situation, with further testing being performed as indicated. Because the prognosis of untreated pulmonary hypertension occurring in the setting of scleroderma is generally quite poor, vigilance is required on the part of physicians following this "at risk" group of patients. The past decade has seen important advances in the treatment of pulmonary arterial hypertension, including intravenous epoprostenol, oral bosentan and subcutaneously infused treprostinil. As new therapies are developed for the treatment of pulmonary arterial hypertension, it is essential that patients with scleroderma-related disease are included in clinical trials.Pacientes com esclerodermia têm risco aumentado para desenvolver hipertensão pulmonar. O aparecimento de dispnéia e/ou a diminuição da capacidade de difusão devem levar à suspeita imediata dessa complicação. A ecodopplercardiografia é importante para o diagnóstico e o seguimento desses casos. Os casos não tratados de hipertensão pulmonar em esclerodermia têm mau prognóstico, daí a necessidade em manter sob vigilância estes pacientes. Na última década surgiram avanços para o tratamento da hipertensão arterial pulmonar, incluindo os medicamentos epoprostenol EV, bosentan VO e treprostinil SC. À medida que novas terapias vão sendo desenvolvidas, torna-se necessário a realização de estudos clínicos de maior validade.

Apresentamos o caso de uma paciente com queixas de tosse produtiva crônica, febre e astenia. Havia utilizado corticóides. A TC do tórax evidenciava consolidação com cavitação de permeio no lobo superior direito. A fibrobroncoscopia demonstrou secreção purulenta em árvore traqueobrônquica e lesão vegetante endobrônquica. Biópsias desta lesão e biópsia transbrônquica foram compatíveis com aspergilose. Diante do quadro clínico, radiológico e histopatológico, o diagnóstico de aspergilose pulmonar necrotizante crônica foi realizado. Tratada com itraconazol, a paciente apresentou boa evolução clínico-radiológica.Chronic necrotizing pulmonary aspergillosis is one of the forms of pulmonary aspergillosis typically found in mildly immunocompromised patients. We report the case of a female patient with complaints of chronic productive cough, fever and asthenia. She reported previous corticosteroid use. A CT scan of the chest revealed consolidation with interposed cavitation in the right upper lobe. Fiberoptic bronchoscopy revealed purulent fluid within the tracheobronchial tree and an endobronchial exophytic lesion. The results of the biopsy of that lesion and the transbronchial biopsy were consistent with aspergillosis. Based on the clinical, radiological and histopathological findings, the patient was diagnosed with chronic necrotizing pulmonary aspergillosis. Treated with itraconazole, the patient presented a favorable clinical-radiological evolution.

    2002-01-01

    Full Text Available A 59-year-old female patient with mitral valve prolapse and a previous history of lumbosacral spondyloarthrosis and lumbar disk hernia had an episode of infective endocarditis due to Streptococcus viridans, which evolved with peripheral embolism to the left kidney, spleen, and left iliac artery, and intraventricular cerebral hemorrhage. Her clinical manifestations were low back pain and hematuria, which were initially attributed to an osteoarticular condition. Infective endocarditis is a severe polymorphic disease with multiple clinical manifestations and it should always be included in the differential diagnosis by clinicians.

    Pincelli Mariangela Pimentel

    2003-01-01

    Full Text Available A síndrome pulmonar e cardiovascular por hantavírus é uma doença de conhecimento relativamente recente e freqüentemente fatal, apresentando-se como síndrome do desconforto respiratório agudo. No Brasil, desde o primeiro surto, relatado em novembro/dezembro de 1993, em Juquitiba, 226 casos já foram registrados pela Fundação Nacional da Saúde. A doença afeta indivíduos previamente hígidos, apresentando-se com pródromo febril e sintomas semelhantes aos de um resfriado comum, podendo rapidamente evoluir para edema pulmonar, insuficiência respiratória aguda e choque. A hemoconcentração e a plaquetopenia são comuns da síndrome pulmonar e cardiovascular por hantavírus, e o quadro radiológico típico é de um infiltrado intersticial bilateral difuso, que progride rapidamente para consolidações alveolares, paralelamente à piora do quadro clínico. A mortalidade inicial era em torno de 75% e declinou para aproximadamente 35%, nos últimos anos. Os pacientes que sobrevivem geralmente recuperam-se completamente, cerca de uma semana após o estabelecimento do quadro respiratório. O agente causal, não reconhecido até há pouco, foi identificado como um hantavírus, cujo reservatório natural são animais roedores da família Muridae, subfamília Sigmodontinae. O tratamento específico antiviral ainda não é bem estabelecido, estando em estudo a eficácia de ribavirina. Cuidados de terapia intensiva como ventilação mecânica e monitoramento hemodinâmico invasivo são necessários nas formas mais graves da doença. Essas medidas, se instituídas precocemente, podem melhorar o prognóstico e a sobrevida dos pacientes com síndrome pulmonar e cardiovascular por hantavírus.

  4. Cases of active infective endocarditis in a university hospital during a 10-year period

    International Nuclear Information System (INIS)

    Objective: To determine the features of patients with active infective endocarditis, and to identify causative microorganisms in blood and/or valve cultures. Methods: The retrospective study was conducted at the Surgical Intensive Care Unit of Istanbul University Cardiology Institute, Istanbul, Turkey, and comprised 22 patients with clinical evidence of the affliction who underwent operation between January 2001 and December 2010. Modified Duke Criteria was used for the diagnosis of the condition. Frequencies and percentages were calculated. Results: The mean age of the patients was 46.68+-18 years, and 12 (54.5%) were male. Native valve endocarditis was present in 13 (59.1%) cases and prosthetic valve endocarditis was present in 9 (40.9%). Rheumatic heart disease was the commonest underlying heart disease (n=12; 54.5%). None of patient was intravenous drug abuser and positive for human immunodeficiency virus. Operative mortality was 18% (n=4). Vegetation and abscess formation were detected in 19 (86.3%) cases. Blood culture positivity was 50% (n=11). Staphylococci was the most common causative micro-organism (n=4; 36.3%), followed by Streptococci (n=3; 27.3%), and 1 (9.1%) each for Enterococci, Brucella species, Candida albicans and Stenotrophomonas maltophilia. Positive cultures from vegetations and tissue retrieved at the operation was not detected. Conclusion: Active IE remains a severe disease affecting the young population in our study and rheumatic heart disease continues to be the most underlying heart disease. Culture negativity was found to be very high and prior antibiotic therapy may be the prime reason. (author)

    We used an experimental rat model to compare the therapeutic efficacy of teicoplanin, linezolid, and quinupristin/dalfopristin with that of vancomycin as standard therapy for infective endocarditis.Aortic endocarditis was induced in rats by insertion of a polyethylene catheter into the left ventricle, followed by intravenous inoculation of 106 colony-forming units of methicillin-resistant Staphylococcus aureus 24 hours later. Forty-eight hours after bacterial challenge, intravenous antibiotic therapies were initiated. There were 6 groups of 8 rats each: uninfected control; infected, untreated control; vancomycin-treated (40 mg/kg twice daily); teicoplanin-treated (20 mg/kg twice daily after a loading dose of 40 mg/kg); linezolid-treated (75 mg/kg 3 times daily for 1 day, then 75 mg/kg twice daily); and quinupristin/dalfopristin-treated (30 mg/kg twice daily and an additional 10 mg/kg dalfopristin infusion over 6 to 12 hr daily). At the end of therapy, the aortic valve vegetations in the drug-treated rats were evaluated microbiologically.Compared with the infected, untreated group, all drug-treated groups had significantly reduced bacterial titers in the vegetations. Vancomycin, teicoplanin, and quinupristin/dalfopristin all effectively reduced the quantitative bacterial cultures of aortic valve vegetations. In addition, there was no significant difference in the comparative efficacy of teicoplanin, linezolid, and quinupristin/dalfopristin. Vancomycin significantly reduced bacterial counts in comparison with linezolid, which was nonetheless also effective.Our experimental model showed that each of the investigated antimicrobial agents was effective in the treatment of infective endocarditis.

    A 61-year-old man was admitted to our hospital with 2-day history of malaise and dyspnea. He had mitral prolapse and type II diabetes mellitus with neurogenic bladder, which was cared for by catheterization on his own. On arrival the patient was in septic condition with hypoxemia, and physical examination revealed systolic murmur at the apex. Transthoracic echocardiography revealed vegetation of the mitral and the aortic valve. The presence of continuous bacteremia was confirmed by multiple sets of blood culture, whereby gram-positive cocci was retrieved and identified as Staphylococcus saprophyticus (S. saprophyticus) both phenotypically and genetically. Because two major criteria of the Modified Duke Criteria were met, the patient was diagnosed with native valve endocarditis due to S. saprophyticus. The urine culture was also positive for gram-positive cocci, phenotypically identified as Staphylococcus warneri, which was subsequently identified as S. saprophyticus with the use of 16S rRNA gene sequence analysis and MALDI-TOF MS (matrix-assisted laser desorption ionization time of flight mass spectrometry), indicating strongly that the intermittent catheterization-associated urinary tract infection resulted in bacteremia that eventually lead to infective endocarditis. This patient was treated with vancomycin and clindamycin. Because of multiple cerebral infarctions, the patient underwent mitral and aortic valve replacement on hospital day 5. Blood culture turned negative at 6th hospital day. Antibiotic therapy was continued for six weeks after surgery. The patient's clinical course was uneventful thereafter, and was discharged home. This is the first case report of native valve endocarditis caused by S. saprophyticus of confirmed urinary origin. PMID:26184852

Thirty two cases were retained for study based on Von Reyn's criteria: 28 native valve endocarditis (27 left and 1 right heart valves) of which 18 occurred on previously undiseased valves (56.3%); 4 cases of left heart prosthetic valve endocarditis. The average age of the patients was 27.5 +/- 14 years and the group comprised 24 women and 8 men (p less than 0.001). Blood cultures were negative in 13 cases, revealed a Gram negative pathogen in 8 cases, a streptoccocus in 3 cases. Blood cultures were not performed in 2 cases. The IE was acute in 18 cases (56.7%) and subacute in 14 cases (43.7%). The dominant clinical signs were of massive and sometimes acute valvular regurgitation (mitral: 21 cases; aortic: 10 cases; mitral and aortic: 3 cases; tricuspid: 1 case). Twenty-six patients had cardiac failure (81.2%): LVF: 15 cases, congestive cardiac failure: 10 cases, RVF: 1 case. The other complications were embolic: cerebral (3 cases), mesenteric (1 case), pulmonary (4 cases). Antibiotic therapy was prescribed in all patients; surgery was required in 9 cases. There were 12 fatalities (37.5%), 10 in the medically treated group and 2 in the surgical group (p less than 0.05). The results show that the prognosis of IE in underdeveloped regions remains poor. Effective strategies of early diagnosis and treatment are urgently required to reduce the high mortality. Prophylaxis of IE should commence with measures to counter the portals of entry of the pathogens and the valvular sequellae of acute rhumatic fever. PMID:2126713

  8. Cases of active infective endocarditis in a university hospital during a 10-year period

    International Nuclear Information System (INIS)

    Objective: To determine the features of patients with active infective endocarditis, and to identify causative microorganisms in blood and/or valve cultures. Methods: The retrospective study was conducted at the Surgical Intensive Care Unit of Istanbul University Cardiology Institute, Istanbul, Turkey, and comprised 22 patients with clinical evidence of the affliction who underwent operation between January 2001 and December 2010. Modified Duke Criteria was used for the diagnosis of the condition. Frequencies and percentages were calculated. Results: The mean age of the patients was 46.68±18 years, and 12 (54.5%) were male. Native valve endocarditis was present in 13 (59.1%) cases and prosthetic valve endocarditis was present in 9 (40.9%). Rheumatic heart disease was the commonest underlying heart disease (n=12; 54.5%). None of patient was intravenous drug abuser and positive for human immunodeficiency virus. Operative mortality was 18% (n=4). Vegetation and abscess formation were detected in 19 (86.3%) cases. Blood culture positivity was 50% (n=11). Staphylococci was the most common causative micro-organism (n=4; 36.3%), followed by Streptococci (n=3; 27.3%), and 1 (9.1%) each for Enterococci, Brucella species, Candida albicans and Stenotrophomonas maltophilia. Positive cultures from vegetations and tissue retrieved at the operation was not detected. Conclusion: Active IE remains a severe disease affecting the young population in our study and rheumatic heart disease continues to be the most underlying heart disease. Culture negativity was found to be very high and prior antibiotic therapy may be the prime reason.

    We describe five patients with positive blood culture for Kocuria species. Three patients had catheter-related bacteraemia and one had infective endocarditis caused by Kocuria kristinae, and one had a K. marina isolate, which was considered to be a contaminant. Identification of the isolates was further confirmed by 16S rRNA gene sequence analysis. In conclusion, Kocuria species are an unusual cause of infection in immunocompromised patients. Accurate identification with molecular methods is imperative for the diagnosis of these unusual pathogens. PMID:20218989

    Abstract Background Most patients with infectious endocarditis (IE) due to Bartonella henselae have a history of exposure to cats and pre-existing heart valve lesions. To date, none of the reported patients have had a history of typical cat scratch disease (CSD) which is also a manifestation of infection with B. henselae. Case presentation Here we report the case of a patient who had CSD and six months later developed IE of the mitral valve caused by B. henselae. Conclusion Based on this uniq...

    Full Text Available Infective endocarditis (IE is today characterized by polyetiology due to a wide range of pathogens. The paper describes the specific features of the clinical picture of the disease in relation to the etiological agent, which have, in some cases, a crucial role in the choice of empiric antibiotic therapy. Significant clinical polymorphism, obscure symptoms, and monosyndromic onset as guises all enhance the importance of the differential diagnosis of IE, at its early stages in particular. Basic approaches to differentiating IE from the diseases in which differentially diagnostic problems arise to the utmost are outlined.

    Surgical treatment of tricuspid valve (TV) endocarditis remains a challenge because of extensive valve destruction, high risk of reinfection, poor outcomes with valve replacement and complex patient compliance issues. Reconstruction of the TV is certainly favoured over replacement; however, diffuse, multifocal vegetations and complete debridement often leave insufficient building materials necessary for repair. We describe our surgical reconstructive technique that relies upon extensive autologous pericardial patch augmentation of the destroyed TV leaflets to establish leaflet coaptation, supplemented with expanded polytetrafluoroethylene neo-chordae and annular reconstruction. We report our outcomes in a series of patients with grossly infected TVs with more than 50% of valvular destruction. PMID:25989809

    Full Text Available Background Infective endocarditis is a common problem and data regarding its clinical and microbiological pattern from developing countries are sparse. We studied clinical features and the microbiological pathogens in patients with Infective Endocarditis in our Hospital. Objective To study the clinical profile and microbiological pathogens involved in patients with Infective Endocarditis, admitted under Department of Internal Medicine of B.P Koirala Institute of Health Sciences. Materials and methods A total of 54 patients with history of fever and underlying heart disease were studied. It was a hospital based cross sectional descriptive study done in patients with infective endocarditis presented to us from March 2007 to February 2008 in B.P Koirala Institute of Health Sciences. Results Out of 54 patients, 11 (20.4% had Dukes definite IE. The male: female ratio was 1.2:1. The mean age of the study group was 27.3 years (range=16-55. In IE group, fever was present in 100% cases (n=11 as it was the inclusion criteria of the study, followed by SOB 81.8% (n=9. History of antibiotic therapy prior to the presentation was present in 36.7 % (n=4 patients. Pallor was the most common sign 63.6% (n=7. Splenomegaly was seen in 18.2% (n=2. Anaemia (Hb<10gm % in 36.4% (n=4 and microscopic haematuria in 72.3% (n=8 cases. Blood culture positivity was seen in 36.4 %. The most common pathogens were Staphylococcus aureus in 27.3% (n=3 and Acinetobacter species in 9.1% (n=1. Conclusion In our study we found that the clinical spectrum of IE was different from the west in that the majority of patients being young in our study. However, RHD still is the commonest underlying heart disease and Staphylococcus aureus being the commonest isolate.

    This is a report of a 25-year-old patient with known aortic valve stenosis since early youth and hemophilia A, showing recurrent joint bleeding. Acute Streptococcus endocarditis induced aortic valve insufficiency resulting in cardiac failure. Aortic valve replacement was performed after substitution of factor VIII, during which intra- and postoperative bleeding was prolonged by pericardial adhesions. Heparin was administered during cardiopulmonary-bypass as usual, but usual postoperative cumarin therapy was not initiated due to prolonged PTT time. One year postoperatively, the patient was in an excellent condition and fully rehabilitated. PMID:3145652

    Full Text Available Abstract Libman-Sacks endocarditis of the mitral valve was first described by Libman and Sacks in 1924. Currently, the sterile verrucous vegetative lesions seen in Libman-Sacks endocarditis are regarded as a cardiac manifestation of both systemic lupus erythematosus (SLE and the antiphospholipid syndrome (APS. Although typically mild and asymptomatic, complications of Libman-Sacks endocarditis may include superimposed bacterial endocarditis, thromboembolic events, and severe valvular regurgitation and/or stenosis requiring surgery. In this study we report two cases of mitral valve repair and two cases of mitral valve replacement for mitral regurgitation (MR caused by Libman-Sacks endocarditis. In addition, we provide a systematic review of the English literature on mitral valve surgery for MR caused by Libman-Sacks endocarditis. This report shows that mitral valve repair is feasible and effective in young patients with relatively stable SLE and/or APS and only localized mitral valve abnormalities caused by Libman-Sacks endocarditis. Both clinical and echocardiographic follow-up after repair show excellent mid- and long-term results.
