Infective endocarditis in pregnancy: A case report / 北京大学学报(医学版)

Infective endocarditis in pregnancy is extremely rare in clinical practice. Guidelines addressing prophylaxis and management of infective endocarditis do not extensively deal with concomitant pregnancy, and case reports on infective endocarditis are scarce. Due to increased blood volume and hemodynamic changes in late pregnancy, endocardial neoplasms are easy to fall off and cause systemic or pulmonary embolism, respiratory, cardiac arrest and sudden death may occur in pregnant women, the fetus can suffer from intrauterine distress and stillbirth at any time, leading to adverse outcomes for pregnant women and fetuses. The disease is dangerous and difficult to treat, which seriously threatens the lives of mothers and babies. Early diagnosis and reasonable treatment can effectively improve the prognosis of patients. The most important method for the treatment of infective endocarditis requires early, adequate, long-term and combined antibiotic therapy. Moreover, surgical controversies regarding indication and timing of treatment exist, especially in pregnancy. In terms of the timing of termination of pregnancy, the timing of cardiac surgery, and the method of surgery, individualized programs must be adopted. A pregnant woman with 30+5 weeks of gestation is reported. She was admitted to hospital due to intermittent chest tightness, suffocation and fever, with grade Ⅲ cardiac insufficiency. Imaging revealed large mitral valve vegetation, 22.0 mm×4.1 mm and 22.0 mm×5.1 mm, respectively, and severe valve regurgitation. Mitral valve perforation was more likely, blood culture suggested Staphylococcus epidermidis infection, after antibiotic conservative treatment, the effect was poor. After the joint consultation including cardiology, neonatology, interventional vascular surgery, anesthesiology, and obstetrics, the combined operation of obstetrics and cardiac surgery was performed in time. The heart was blocked for 60 minutes, the bleeding was 1 200 mL, the newborn was mildly asphyxiated after birth, and the birth weight was 1 890 g. Nine days after the operation, the patient was discharged from the hospital, and the newborn was discharged with the weight of 2 020 g. Critical cases like this require a thorough weighing of risks and benefits followed by swift action to protect the mother and her unborn child. An optimal outcome in a challenging case like this greatly depends on effective interdisciplinary communication, informed consent of the patient, and concerted action among the specialists involved.

Antifungal efficacy of amphotericin b in candida albicans endocarditis therapy: systematic review

Abstract Introduction: Although it is the most common agent among the fungal causes of endocarditis, Candida albicans endocarditis is rare. Objective: To evaluate the efficacy of amphotericin B in the treatment of C. albicans endocarditis beyond a systematic review. Data search: Articles in English, Spanish and Portuguese, conducted in the following databases: MEDLINE, LILACS, IBECS and SciELO, in humans and published in the last 25 years. Study selection: Observational studies, clinical trials, and case series providing data on the amphotericin B use in patients with a C. albicans endocarditis diagnosis without age limitations. Data synthesis: From the initial search (n=79), 25 articles were fully evaluated, of which 19 were excluded for meeting one or more exclusion criteria, remaining five articles (two observational studies and three case series). Patients using amphotericin B demonstrated improvement in survival rates, and its main use was in association with the surgical method as well as with caspofungin association. Conclusion: Literature lacks evidence to conclude about efficacy and safety of amphotericin B in the treatment of fungal endocarditis. Randomized clinical trials are necessary to provide better evidence on the subject.

Activador tisular del plasminógeno recombinante para el tratamiento de la vegetación intracardíaca en un lactante de muy bajo peso al nacer / Recombinant tissue plasminogen activator treatment for intracardiac vegetation in a very low birth weight infant

Las nuevas opciones de tratamiento prolongan la hospitalización y aumentan las infecciones intrahospitalarias bacterianas y fúngicas, pero también mejoran la sobrevida de los recién nacidos hospitalizados en la unidad de cuidados intensivos neonatales. Las infecciones fúngicas invasivas en neonatos están asociadas con una morbimortalidad significativa. También pueden diseminarse a órganos específicos y causar endocarditis, endoftalmitis, artritis séptica, nefropatía obstructiva y meningitis. En el caso de la endocarditis, se recomiendan tratamientos antimicóticos sistémicos agresivos y, en algunos casos, la intervención quirúrgica del neonato. Informamos el caso de un lactante prematuro, de bajo peso al nacer, con vegetación intracardíaca. Esta es una complicación rara y potencialmente mortal de infecciones fúngicas invasivas. El paciente recibió tratamiento con caspofungina y un activador tisular del plasminógeno recombinante, en vez de una intervención quirúrgica.

Developing treatment options have resulted in prolonged admission and increased bacterial and fungal nosocomial infections as well as improved survival in neonatal intensive care unit. Invasive fungal infections in newborns are associated with significant morbidity and mortality and can cause endorgan dissemination such as endocarditis, endophthalmitis, septic arthritis, obstructive nephropathy and meningitis. Endocarditis requires aggressive systemic antifungal therapy and sometimes surgical intervention in neonates. We report a low birth weight premature infant with intracardiac vegetation that is rare and a life-threatening complication of invasive fungal infections. He was treated with caspofungin and recombinant tissue plasminogen activator in stead of surgical intervention.

Endocarditis fúngica, una causa infrecuente de lesión en válvula cardiaca nativa / Fungal endocarditis, an uncommon cause of native cardiac valve disease

Introducción: La endocarditis fúngica (EF) es una forma grave de endocarditis infecciosa (EI), asociada a una alta morbimortalidad. Su incidencia es baja y se puede presentar después de una cirugía cardiaca, uso de válvula cardiaca protésica, catéteres endovenosos centrales (CVC), etc. Presentación del caso: Hombre de 17 años con antecedente de enfermedad renal crónica en hemodiálisis y múltiples hospitalizaciones por septicemia asociada a CVC, presentó cuadro febril el cual fue tratado con antibióticos y cambio de CVC. Estudio con hemocultivos resultó positivo para Candida parapsilosis. Se decidió hospitalización domiciliaria y tratamiento con Fluconazol. Persistió febril por lo que se decidió hospitalización por sepsis fúngica persistente y continuar tratamiento antimicótico. Estudio con ecocardiograma mostró endocarditis mitral con vegetación móvil en velo anterior e insuficiencia moderada. Se decidió tratamiento quirúrgico, realizándose reemplazo de válvula mitral con prótesis cardiaca biológica. En el intraoperatorio se observó vegetación verrugosa y móvil. Cultivos y estudio histopatológico confirmó EF. Evolucionó con candidemia persistente, pero sin hallazgos ecográficos de endocarditis. Control con tomografía computada demostró hallazgos sugerentes de candidiasis crónica diseminada (CCD), modificándose el tratamiento con Caspofungina y Voriconazol. Al cuarto mes postoperatorio fue dado de alta con tratamiento antifúngico crónico. Discusión: La EF es un tipo infrecuente de endocarditis infecciosa constituyendo un 6% de los casos. Se asocia a una alta mortalidad a pesar de tratamiento médico y quirúrgico combinado. La CCD es una forma infrecuente de candidemia, casi exclusiva de pacientes oncohematológicos. El antecedente de factores de riesgo obliga a sospecharlo.

Introduction: Fungal endocarditis (EF) is a severe form of infectious endocarditis (IE) associated with high morbidity and mortality. Its incidence is low and may be related to heart surgery using prosthetic heart valve, central intravenous catheters (CVC), etc. Case report: Man aged 17 with a history of chronic kidney disease on hemodialysis, and multiple hospitalizations for sepsis associated to CVC, presented febrile illness, which was treated with antibiotics and CVC change. Blood culture study was positive for Candida parapsilosis. Home hospitalization and treatment with Fluconazole was decided. He persisted febrile so hospitalization it was decided by persistent fungal sepsis and to continue antifungal therapy. Echocardiogram study showed mitral endocarditis with mobile vegetation anterior leaflet and mitral insufficiency. Surgical treatment was decided. Mitral valve replacement surgery with biological cardiac prosthesis is performed. A warty and mobile vegetation was observed in the surgery. Cultures and histopathology confirmed EF. He evolved with persistent candidemia, but without sonographic findings of endocarditis. Control with computed tomography showed suggestive findings of chronic disseminated candidiasis (CCD), modifying treatment with Caspofungin and Voriconazole. The fourth postoperative month was discharged with chronic antifungal treatment. Discussion: EF is a rare type of EI constitutes 6% of cases. It is associated with high mortality despite combined medical and surgical treatment. The CCD is an almost exclusive rare form of candidemia in oncohematological patients. The history of risk factors forcing suspect.

Prosthetic aortic valve endocarditis due to Ochrobactrum anthropi.

Ochrobactrum anthropi is an emerging pathogen increasingly affecting the immunocompromised host. Only four cases of infective endocarditis have been documented in literature. Therapeutic approach is a rising challenge as it is resistant to most of the currently available beta lactam antibiotics with the exception of carbapenems. We report a case of prosthetic valve endocarditis secondary to Ochrobactrum anthropi infection; the host was temporarily immunocompromised due to disseminated herpes zoster after surgery.

Clinical features and outcome of infective endocarditis in Yemeni patients treated with empirical antibiotic therapy

Infective endocarditis is a common disease in Yemen. Although the incidence of rheumatic valvular disease and uncorrected congenital heart disease in adults is high in Yemen, there are few data regarding the pattern, characteristic features and outcome of infective endocarditis in Yemen. The aim was to study the characteristic, clinical features and diagnostic criteria of infective endocarditis in Yemeni patients and the outcome in patients treated with medical therapy. Seventy-two consecutive patients admitted to Kuwait teaching hospital in Sana'a with suspected infective endocarditis between June 1, 2005 and June 1, 2007 were included in this study. A questionnaire including history, clinical findings, and result of requested investigations, treatment, complications and outcome was used. The diagnosis was based on Dukes criteria, which proposed two major or five minor criteria. In our study, we included raised erythrocyte sedimentation rate [ESR] as a minor criteria. The patients were classified as definite, possible and rejected cases. All patients received empirical antibiotic therapy. The mean age was 28.56 +/- 14.5 years. Men were 30 [42.2%] while women were 42 [57.7%]. 59 [81.9%] of the patients had been admitted due to fever. Past history of rheumatic heart disease was positive in 38 [53.3%] of the patients. Mitral regurgitation was the commonest form of valvular affection 54 [82.1%] of patients followed by aortic regurgitation in 45 [63%]. Anemia was present in 53 [74%] while raised erythrocyte sedimentation rate was high in all patients. Vegetations were detected by transthorasic echocardiography in 51 [70.83%] of the patients while blood culture was positive in only 7 [9.6%]. After adding high ESR to the criteria, definite infective endocarditis were found in 34 [47.2%]; possible in 38 [52.7%] and no rejected patients. Sixty-two [87.5%] of the patients improved and were discharged in good general condition. Nine patients died, an In hospital mortality of 12.5%. Patients with IE in Yemen were younger than those patients in western countries, RHD is the commonest predisposing factor. Duke's criteria in addition to high ESR as minor criteria improved the diagnostic possibilities and using empirical antibiotic therapy improves the outcome

Infective endocarditis: prognostic stratification and indications for valve surgery.

Significant advances have been made in the management of infective endocarditis with the advent of antimicrobial therapy, surgery and transesophageal echocardiography, bringing hope to patients suffering from this once uniformly fatal illness. However, recent studies show that the mortality from infective endocarditis is still in the order of 20-30%. The prognostic determinants for adverse outcomes and the indications for surgical therapy in patients with infective endocarditis have recently received renewed attention. Our current understanding of these controversial issues will be reviewed in this paper.

Endocarditis caused by Abiotrophia defectiva

A 35-year-old man with pre-existing rheumatic heart disease and aortic regurgitation [AR] presented with intermittent fever, ankle swelling and clinical evidence of endocarditis. Transoesophageal echocardiogram [TEE] revealed vegetations and destruction of the aortic valve [AV]. Blood cultures grew a gram positive coccobacillus which was phenotypically identified as Abiotrophia defectvia [A.defectiva]. A diagnosis of infective endocarditis [IE] due to A.defectiva was made. Treatment, with penicillin and gentamicin, was administered for 4 weeks. Mechanical valve replacement was required few days after starting the antibiotic therapy. The patient had a favorable outcome on follow up. Although A.defectiva is an uncommon cause of endocarditis, early and correct identification of this pathogen is important to improve the outcome and the prognosis of patients with IE due to this organism

Candida tropicalis causing prosthetic valve endocarditis.

The incidence of endocarditis produced by the so-called "opportunists" as a complication of prosthetic valve surgery is progressively increasing in frequency and gradually transforming the clinical picture habitually associated with this disease. Candida endocarditis is an unusual but severe complication caused by Candida albicans or other fungal species. This case and a review of the literature indicate that Candida endocarditis treated with amphotericin B and prosthetic valve replacement may recur months after treatment, and that late recurrent Candida endocarditis, which is difficult to diagnose and treat, may be best prevented by lifelong antifungal suppressive therapy.

Endocardite de Libmann-Sacks e anticoagulação oral / Libman-Sacks endocarditis and oral anticoagulation

Paciente de 34 anos, com lúpus eritematoso sistêmico e síndrome de anticorpo antifosfolípide secundária, evoluiu com crises convulsivas, parcialmente controladas com anticonvulsivante, e ausculta de sopro cardíaco, cuja propedêutica mostrou a presença de vegetação em valva mitral. Diante do diagnóstico de endocardite de Libman-Sacks foi iniciada terapia com warfarina sódica, e após seis meses de anticoagulação oral, a paciente apresentava controle total das crises convulsivas e desaparecimento da vegetação valvar ao ecocardiograma. São discutidas a ocorrência da endocardite de Libman-Sacks no lúpus eritematoso sistêmico, sua associação com a síndrome de anticorpo antifosfolípide e a terapêutica anticoagulante, e feita uma revisão da literatura.

Tratamiento con caspofungina de endocarditis por Candida tropicalis resistente a fluconazol / Treatment with caspofungin of Candida tropicalis endocarditis resistant to fluconazol

Fungal endocarditis, in particular due to Candida species, requires medical and surgical treatment and amphotericin B is the drug of choice. Caspofungin is an echinocandin very effective against Candida and Aspergillus. We present a patient with Candida tropicalis endocarditis, fluconazol resistant, treated with caspofungin, on a compassional basis as a result of adverse effects with amphotericin B. The patient had a microbiological response.

Las endocarditis causadas por hongos, (Candida en particular), requieren tratamiento médico-quirúrgico,siendo la anfotericina B la droga de elección. Caspofungina es una equinocandina con gran actividadsobre Candida y Aspergillus. Se presenta un paciente con una endocarditis por Candida tropicalis resistente a fluconazol tratado con caspofungina bajo un esquema de salvataje, luego de haber presentado efectos adversos por anfotericina B. El paciente tuvo respuesta microbiológica.

In-vitro activity of synercid and related drugs against streptococcus oralis isolated from septicaemia and endocarditis cases

Objective - The increase in resistance to gram positive organisms and seriousness of infective endocarditis, makes it necessary to look for an alternate treatment. Method- In-vitro activity of synercid was compared with penicillin, amoxycillin, teicoplanin, vancomycin, clindamycin and erythromycin. Result - Synercid showed minimum inhibitory concentrations [MIC] within the narrow range of 0.06-0.5 mg/I. MIC50 and mode values were both 0.25 mg/I. There was just two-fold difference between the MIC50 [0.25 mg/I] and the MIC90, [0.5 mg/I]. Although the MICs of synercid for S. oralis were relatively high compared to penicillin, clindamycin, erythromycin and teicoplanin, the in-vitro bactericidal activity of synercid was much greater. Synercid MBC values were < 4 mg/I for most of the isolates, except for one of 16 mg/I and the other >64 mg/I. Killing curve was performed on six isolates of S. oralis from infective endocarditis, two from septicaemia patients and two from the oral flora of normal individuals. Conclusion - Synercid showed superior bactericidal activity when compared to penicillin and vancomycin against all ten isolates of S. oralis tested. Synercid was bactericidal [99.9% kill] against all ten isolates of S. oralis within six hours of contact

Tratamiento medico exitoso de una endocarditis en valvula protesica por Candida tropicalis / Successful medical treatment of Candida tropicalis in prosthetic valve endocarditis

La curación sin cirugía de la endocarditis micótica en válvula protésica es raramente descripta. Comunicamos un caso de endocarditis por Candida tropicalis sobre una prótese biológica en posición tricuspídea, en la que se consideró que la cirurgía estaba contraindicada. Se había identificado una gran vegetación sobre la prótesis biológica. Se inició tratamiento antimicótico, observándose mejoría progressiva del cuadro y desaparición de la vegetación a lo largo de 15 meses de seguimiento. El tratamiento completó 2 gr de anfotericina B para continuar luego con fluconazol. Nuestra paciente representa el primer caso de endocarditis en válvula protésica por Candida tropicalis que sobrevive sin cirugía.

Endocarditis de valvula nativa producida por Lactobacillus casei sub. rhamnosus refractaria al tratamiento con antimicrobianos / Native-valve endocarditis produced by Lactobacillus casei sub. rhamnosus refractory to antimicrobial therapy

La endocarditis producida por Lactobacillus spp. es una infección infrecuente. Se han descrito 42 casos desde 1938 hasta la fecha y sólo 17 de ellos evolucionaron favorablemente con tratamiento médico, sin necesidad de reemplazo valvular. Si bien se han publicado unos pocos casos de infecciones producidas por Lactobacillus spp. en nuestro país, ninguno de ellos correspondió a endocarditis infecciosa. Se presenta un caso de endocarditis producida por Lactobacíllus casei sub. rhamnosus vancomicinaresistente en un varón de 29 años con antecedentes de prolapso de válvula mitral, que requirió reemplazo valvular para su curación, debido al fracaso del tratamiento con penicilina y gentamicina. El enfermo presentó una evolución favorable en el post-operatorio inmediato y fue dado de alta a los 7 días en buen estado general, no presentando signos ni síntomas de recurrencia en los controles realizados durantes los 2 años siguientes. Enfatizamos la necesidad de identificar rapidamente el género Lactobacíllus ante un aislamiento de hemocultivos de enfermos con endocarditis, puesto que dicho género puede confundirse con otras especies que se asocian más frecuentemente con esta patologia y que generalmente presentan respuesta clínica favorable frente a los tratamientos con antimicrobianos. Sugerimos que se considere la posibilidad de un reemplazo valvular precoz ante la presencia de endocarditis producida por Lactobacillus spp.

Avanços em clínica cardiológica: Parte 2. Estenose mitral / Advances in clinical cardiology: Part 2. Mitral stenosis

A estenose mitral é geralmente reumática e é considerada grave quando a área é menor do que 1cm². A fibrilaçäo atrial e a embolia säo as complicaçöes mais temidas. O grande avanço na conduçäo destes casos acha-se representado pela ecocardiografia doppler. O tratamento clínico inclui a prevençäo da febre reumática e da endocardite, bem como o uso judicioso de diuréticos, digitálicos e antiarrítmicos. O tratamento invasivo tem condiçöes próprias, incluindo a comissurotomia cirúrgica e fechada, a valvuloplastia e a troca valvar. Infelismente a reestenose ainda é relativamente freqüente
