Vasculitis and cerebral hemorrhage due to Streptococcus gordonii infectious endocarditis: A case report.

Infective endocarditis is an infection of the heart with systemic consequences, both infectious and non-infectious. Infective endocarditis can affect several systems, one of which is the central nervous system. The most common form of presentation is ischemic stroke; however, intracranial hemorrhage can occur due to immune-mediated damage to the vessel wall. The former further complicates cardiac surgical procedures when necessary. We present here the case of a 21-year-old male patient, with no personal medical history, who presented with intracranial hemorrhage due to a vasculitis phenomenon, caused by Streptococcus gordonii infective endocarditis. The patient underwent emergency drainage of the intracranial hemorrhage and minimally invasive valve surgery in 17 days, with satisfactory postoperative recovery and follow-up.

Endocarditis due to Candida albicans in an immunocompromised patient: A case report.

BACKGROUND: Fungal endocarditis is a low-frequency disease with a challenging diagnosis, as it can be mistaken with bacterial endocarditis. Fungal endocarditis causes higher mortality rates in immunocompromised patients. In the clinical practice, the endocarditis caused by fungi represents up to 10% of all infectious endocarditis cases and has a mortality rate of nearly 50%. CASE REPORT: Here we present the case of a 53-year-old woman under corticosteroid therapy with a history of rheumatic heart disease, aortic valve replacement, and rheumatoid arthritis, who presented with fungal endocarditis caused by Candida albicans. Even though the patient received 3 years of antifungal prophylaxis with fluconazole, had valve replacement surgery, and received intensive care, the patient finally worsened and died. CONCLUSIONS: Comorbidities and corticosteroid therapy predisposed the patient to acquire fungal endocarditis. This case highlights the importance of implementing procedures for the isolation and identification of fungi, and for carrying out antifungal-susceptibility testing, as well as establishing surveillance programs to identify infection-causing species and drug resistance patterns in hospitals. Moreover, designing and upgrading the algorithm for infectious endocarditis is the key to future improvements in diagnosis.

Infectious endocarditis without intracardiac devices or underlying structural heart disease.

OBJECTIVE: To describe clinical, microbiological and echocardiographic aspects of endocarditis in a specific group of patients without intracardiac devices or underlying structural heart disease. METHOD: Retrospective study, clinical records and echocardiographic reports were reviewed during the period 1997 to 2020. Duke's modified criteria were applied. Statistical analysis: univariate expressed in frequencies, using measures of dispersion and central tendency. RESULTS: 30,000 echocardiographic reports were reviewed, only 1350 had infectious endocarditis as a reason for sending, of which 248 cases were selected. The mean age was 48.1 ± 16.7 years. 140 men (56%) and 108 women (44%). The most frequent echocardiographic sign was vegetation, in 278 (93.60%), and most common location was mitral (35.55%), with a higher number of cases in the right ventricle than expected. The most common systemic disease was kidney disease, in 135 (41.08%). A case of Streptococcus thoraltensis not previously reported in Mexico was identified. CONCLUSIONS: The presence of infectious endocarditis has increased due to invasive in-hospital and drug procedures. Due to their complexity, multidisciplinary teams are indispensable.

OBJETIVO: Describir aspectos clínicos, microbiológicos y ecocardiográficos de endocarditis en un grupo específico de pacientes sin dispositivos intracardiacos ni cardiopatía estructural subyacente. MÉTODO: Estudio retrospectivo en el que se revisaron expedientes clínicos y reportes ecocardiográficos durante el periodo de 1997 a 2020. Se aplicaron los criterios modificados de Duke. Se describió la muestra por edad, sexo, enfermedad sistémica, vegetaciones y agente microbiológico. Se excluyeron pacientes con cardiopatía estructural o Libman-Sacks. Análisis estadístico: univariado expresado en frecuencias, utilizando medidas de dispersión y tendencia central. RESULTADOS: Se revisaron 30,000 reportes ecocardiográficos, de los cuales solo 1350 tenían como motivo de envío endocarditis infecciosa, y de estos se seleccionaron 248 casos. La edad promedio fue de 48.1 ± 16.7 años. Hubo 140 hombres (56%) y 108 mujeres (44%). El signo ecocardiográfico más frecuente fue la vegetación, en 278 (93.60%), y la ubicación más común fue mitral (35.55%), con un número mayor de casos en el ventrículo derecho de lo esperado. La enfermedad sistémica más común fue la enfermedad renal, en 135 (41.08%). Se identificó un caso de Streptococcus thoraltensis no reportado previamente en México. CONCLUSIONES: La presencia de endocarditis infecciosa ha aumentado debido a procedimientos invasivos intrahospitalarios y fármacos. Por su complejidad, los equipos multidisciplinarios son indispensables.

Effect of promethazine on biofilms of gram-positive cocci associated with infectious endocarditis.

This study evaluated the antimicrobial activity of promethazine against Staphylococcus aureus, Staphylococcus epidermidis and Streptococcus mutans and its effect on the antimicrobial susceptibility of biofilms grown in vitro and ex vivo on porcine heart valves. Promethazine was evaluated alone and in combination with vancomycin and oxacillin against Staphylococcus spp. and vancomycin and ceftriaxone against S. mutans in planktonic form and biofilms grown in vitro and ex vivo. Promethazine minimum inhibitory concentration range was 24.4-95.31 µg/mL and minimum biofilm eradication concentration range was 781.25-3.125 µg/mL. Promethazine interacted synergistically with vancomycin, oxacillin and ceftriaxone against biofilms in vitro. Promethazine alone reduced (p < 0.05) the CFU-counts of biofilms grown on heart valves for Staphylococcus spp., but not for S. mutans, and increased (p < 0.05) the activity of vancomycin, oxacillin and ceftriaxone against biofilms of Gram-positive cocci grown ex vivo. These findings bring perspectives for repurposing promethazine as adjuvant in the treatment of infective endocarditis.

Endocarditis infecciosa en canino con diagnóstico previo de síndrome vestibular periférico secundario a probable otitis media-interna: reporte de caso / Infectious Endocarditis in Dogs with a Previous Diagnosis of Peripheral Vestibular Syndrome Secondary to Probable Otitis Media-Interna: A Case Report

Resumen La endocarditis infecciosa es un proceso patológico de baja incidencia en la clínica diaria; su principal etiología son los agentes bacterianos, los cuales colonizan con mayor prevalencia de válvula mitral y aortica. En este artículo se presenta el estudio de un perro con diagnóstico previo de síndrome vestibular periférico secundario a probable otitis media-interna. Se presenta con un soplo de aparición súbita, claudicaciones intermitentes, inapetencia, depresión y fiebre, por lo cual se hace la valoración ecocardiográfica, donde se evidencia engrosamiento valvular mitral, acompañado de estructuras hiperecoicas en el borde libre que corresponden a lesiones vegetativas. Por medio de los criterios de Duke modificados se obtiene un diagnóstico definitivo de endocarditis infecciosa, para lo cual se realiza manejo médico intrahospitalario, sin evolución favorable. Los hallazgos clínicos y paraclínicos coinciden con lo reportado en la literatura. Los criterios de Duke modificados permiten orientar el diagnóstico y evidenciar signos clínicos de alarma. El manejo médico antimicrobiano deberá realizarse con base en hemocultivos y pruebas de sensibilidad, siempre teniendo en cuenta la prevalencia de patógenos y el origen primario de la infección. Se debe considerar como una patología con un pronóstico malo y un porcentaje de fatalidad alto. Finalmente, se concluye que la principal limitación del caso es la falta de confirmación histopatológica.

Abstract Infectious endocarditis is a pathological process with low incidence in the daily clinical practice. The main etiology are the bacterial agents that colonize with higher prevalence the mitral and aortic valves. This paper reports the case of a dog with a previous diagnosis of peripheral vestibular syndrome secondary to probable otitis media-interna. The dog has a sudden heart murmur, intermittent claudications, lack of appetite, depression and temperatures. It is performed an echocardiographic assessment that shows mitral valve thickening with hyperecoic structures in the free border that indicates vegetations. Using the Modified Duke Criteria, a definitive diagnosis of infectious endocarditis is concluded. The dog is provided a medical treatment at the clinic without success. The clinical and paraclinical findings match the background found in the literature. Modified Duke Criteria allow guiding the diagnosis process and uncovering the alarm clinical signs. Antimicrobial clinical treatment must be administered based on blood cultures and sensitivity tests and considering both the pathogen prevalence and infection primary origin. Doctors must deem this condition as a bad prognosis pathology with a high mortality percentage. Finally, it is concluded that the main limitation in this case is a lack of histopathological confirmation.

Epidemiological and clinical profile of infective endocarditis at a Brazilian tertiary care center: an eight-year prospective study

Abstract INTRODUCTION: Infective endocarditis (IE) is a systemic infectious disease requiring a multidisciplinary team for treatment. This study presents the epidemiological and clinical data of 73 cases of IE in Rio de Janeiro, Brazil. METHODS This observational prospective cohort study of endocarditis patients during an eight-year study period described 73 episodes of IE in 70 patients (three had IE twice). Community-associated (CAIE) and healthcare-acquired infective endocarditis (HAIE) were diagnosed according to the modified Duke criteria. The collected data included demographic, epidemiologic, and clinical characteristics, including results of blood cultures, echocardiographic findings, surgical interventions, and outcome. RESULTS: Analysis of data from the eight-year study period and 73 cases (70 patients) of IE showed a mean age of 46 years (SD=2.5 years; 1-84 years) and that 65.7% were male patients. The prevalence of CAIE and HAIE was 32.9% and 67.1%, respectively. Staphylococcus aureus (30.1%), Enterococcus spp. (19.1%), and Streptococcus spp. (15.0%) were the prevalent microorganisms. The relevant signals and symptoms were fever (97.2%; mean 38.6 + 0.05°C) and heart murmur (87.6%). Vegetations were observed in the mitral (41.1%) and aortic (27.4%) valves. The mortality rate of the cases was 47.9%. CONCLUSIONS: In multivariate analysis, chronic renal failure (relative risk [RR]= 1.60; 95% confidence interval [CI] 1.01-2.55), septic shock (RR= 2.19; 95% CI 1.499-3.22), and age over 60 years (RR= 2.28; 95% CI 1.44-3.59) were indirectly associated with in-hospital mortality. The best prognosis was related to the performance of cardiovascular surgery (hazard ratio [HR]= 0.51; 95% CI 0.26-0.99).

Bacteremia after supragingival scaling and dental extraction: Culture and molecular analyses.

OBJECTIVE: To study the incidence and magnitude of bacteremia after dental extraction and supragingival scaling. SUBJECTS AND METHODS: Blood samples were taken before and 5 and 30 min after dental extraction and supragingival scaling from individuals at high (n = 44) or negligible risk (n = 51) for infective endocarditis. The former received prophylactic antibiotic therapy. Samples were subjected to aerobic and anaerobic culture and quantitative real-time polymerase chain reaction to determine the incidence of bacteremia and total bacterial levels. RESULTS: Patients who did not receive prophylactic antibiotic therapy had a higher incidence of positive blood cultures (30% 5 min after extraction) than patients who received prophylactic antibiotic therapy (0% 5 min after extraction; p < .01). Molecular analysis did not reveal significant differences in the incidence or magnitude of bacteremia between the two patient groups either 5 or 30 min after each of the procedures evaluated. Extraction was associated with higher incidence of bacteremia than supragingival scaling by blood culture (p = .03) and molecular analysis (p = .05). CONCLUSIONS: Molecular methods revealed that dental extraction and supragingival scaling were associated with similar incidence of bacteremia in groups receiving or not prophylactic antibiotic therapy. However, blood culture revealed that antibiotic therapy reduced viable cultivable bacteria in the bloodstream in the extraction group.

Endocarditis infecciosa / Infective endocarditis / Endocardite infecciosa

La endocarditis infecciosa es una enfermedad producida por la colonización y proliferación de agentes infecciosos en la superficie endotelial del corazón. Su presentación clínica es variable pues depende de condiciones propias del hospedero, tales como el estado inmunológico, la presencia de material protésico y el uso de drogas endovenosas, y del agente causal. El diagnóstico se establece, usualmente, mediante la suma de elementos como la historia clínica, el examen físico, los hemocultivos, el ecocardiograma y otras ayudas. Presentamos el caso de un hombre adulto que acudió al hospital con un cuadro clínico de fiebre e insuficiencia cardíaca aguda. Se documentó la presencia de soplo sistólico en el foco aórtico y el ecocardiograma reveló insuficiencia valvular grave y una lesión vegetante sobre la válvula aórtica bicúspide. Requirió reemplazo valvular y completó el tratamiento antibiótico, dirigido por la sensibilidad demostrada, luego de hemocultivos positivos para Streptococcus mitis.

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

O diagnóstico se estabelece, usualmente, mediante a soma de elementos como a história clínica, o exame físico, os resultados de hemocultura, o ecocardiograma e outras ajudas. Apresentamos o caso de um homem adulto que foi ao hospital com quadro clínico de febre e insuficiência cardíaca aguda. Documentouse a presença de sopro sistólico no foco aórtico e o ecocardiograma revelou insuficiência valvular grave e uma lesão vegetante sobre a válvula aórtica bicúspide. Requereu substituição valvular e completou o tratamento antibiótico, dirigido pela sensibilidade demonstrada, depois de hemocultivos positivos para Streptococcus mitis.

Endocarditis by Kocuria rosea in an immunocompetent child.

Kocuria rosea belongs to genus Kocuria (Micrococcaceae family, suborder Micrococcineae, order Actinomycetales) that includes about 11 species of bacteria. Usually, Kocuria sp are commensal organisms that colonize oropharynx, skin and mucous membrane; Kocuria sp infections have been described in the last decade commonly affecting immunocompromised patients, using intravenous catheter or peritoneal dialysis. These patients had mainly bacteremia/recurrent sepsis. We hereby describe the case of a 10-year-old girl, immunocompetent, who had endocarditis/sepsis by K. rosea which was identified in five different blood cultures by Vitek 2 ID-GPC card (BioMérieux, France). Negative HIV serology, blood count within normal range of leukocytes/neutrophils and lymphocytes, normal fractions of the complement, normal level of immunoglobulins for the age; lymphocyte immunophenotyping was also within the expected values. Thymus image was normal at chest MRI. No catheters were required. Identification of K. rosea was essential to this case, allowing the differentiation of coagulase-negative staphylococci and use of an effective antibiotic treatment. Careful laboratory analysis of Gram-positive blood-born infections may reveal more cases of Kocuria sp infections in immunocompetent patients, which may collaborate for a better understanding, prevention and early treatment of these infections in pediatrics.

Endocarditis infecciosa, experiencia de diez años en un centro de referencia nacional / Infectious endocarditis, 10 years of experience in a national reference center

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

Objective: to study the clinical, epidemiological and microbiological characteristics as well as the surgical medical treatment of patients admitted diagnosed with infectious endocarditis to deepen in its study and to contribute to a better treatment for these patients. Methods: twenty four patients from whole country, discharged with the diagnosis of infectious endocarditis. Data were collect from the medical records of the "William Soler" Children Hospital files and from the database of surgery service of heart center. The frequency of different manifestations of infectious endocarditis was determined according to: age groups, risk factors and the more frequent clinical, laboratory and microbiologic data. Also, the predominant valvular take, the etiology and the response to antibiotics were determined. Results: the more involved age group was between 5 and 18 years; the previous heart disease was the more predominant factor; the more frequent symptoms and signs were: fever, anorexia and weight loss. The heart failure and the pulmonary embolism were frequent complications. Most of patients had an accelerated erythrosedimentation and the fourth of cases had negative blood cultures. The aortic and mitral valves were the more involved and the predominant clinical course was the subacute. In almost the half of patients the infection had a nosocomial origin. The more used antimicrobial agents were amikacin, vancomycin and ceftriaxone. Conclusions: the infectious endocarditis is uncommon in our institution occurs more often in relation to congenital heart diseases. The more constant clinical facts were fever and a history of previous heart disease(AU)
