burkholderia endocarditis

A 37-year-old male with a past medical history of previous mitral valve replacement due to bacterial endocarditis and intravenous (IV) drug use was found to have Burkholderia cepacia bacteremia. Transesophageal echocardiogram revealed large mitral and tricuspid valve vegetations. Medical management was initially attempted but his bacteremia persisted, and he required urgent prosthetic mitral valve replacement and native tricuspid valve replacement. Prosthetic valve endocarditis has been associated with surgery in 48...

Melioidosis is an endemic disease to several regions and occurs predominantly in Southern Asia, Northern Australia, China and Taiwan. In South America, Colombia is second after Brazil in number of melioidosis cases reported. Clinical manifestation varies from asymptomatic infection to multiorgan compromise involving multiple abscesses and septic shock. Cardiac compromise is infrequent, with an incidence of <1%. We report the case of a 51-year-old patient from Colombia with a mechanical aortic valve who had an abscess in right leg and in the prosthetic valve...

During March 2016-January 2019, Burkholderia cepacia complex (BCC) infection developed in 13 persons who inject drugs (PWID) in Kowloon West Region, Hong Kong, China. Seven cases were infective spondylitis, 2 endocarditis, 2 septic arthritis, 1 intramuscular abscess and bacteremia, and 1 necrotizing fasciitis. Pulsed-field gel electrophoresis revealed that the isolates from 9 patients were clonally related. This clone caused major illness, and 11 of the 13 patients required surgical treatment. Clinicians should be aware of this pathogen and the appropriate broad-spectrum antimicrobial drugs to empirically prescribe for PWID with this life-threatening infection...

Melioidosis is caused by the gram-negative environmental saprophyte, Burkholderia pseudomallei ( B. pseudomallei ). Common presentations include pneumonia, bone and joint disease, renal and soft tissue infections. However, head and neck involvement is rare. We report a jugular lymphnode abscess associated with facial percutaneous inoculation of B. pseudomallei . Hospital course was complicated by endocarditis, septic arthritis and pyelonephritis. Surgical drainage and intensive and eradicative phase of antibiotics successfully cured the disease...

Melioidosis is caused by Gram-negative bacterium Burkholderia pseudomallei . Clinical presentation can vary from pneumonia, sepsis and multi-focal abscess formation. The aim of this study was to systemically review the cardiac manifestations of melioidosis in the literature and describe their epidemiology, microbiological diagnosis and outcomes. A systematic review of the peer-reviewed literature was carried out in PubMed and Google Scholar for human melioidosis cases with cardiac involvement. Quantitative data for cases of melioidosis were obtained, including age, sex, microbiological diagnosis, treatment, and outcome...

Burkholderia cepacia prosthetic valve endocarditis (PVE) is extremely rare, with few cases in the literature. A report of a patient with PVE is described, followed by a literature review on B. cepacia PVE. A 38 year old man with poor dentition and a history of intravenous drug use (IVDU) and mitral valve replacement was found to have a mitral valve vegetation. Five sets of blood cultures on different days grew B. cepacia . Individual sets of blood cultures on different dates also isolated S. viridans (outside hospital culture), methicillin-resistant S...

BACKGROUND: Burkholderia pseudomallei is a Gram negative, soil-water saprophytic bacterium endemic in South-East Asia and Northern Australia. Melioidosis is being increasingly diagnosed in other regions like India, China, and Sri Lanka during recent years. The clinical presentation of melioidosis is extremely variable. CASE SUMMARY: We present a case of melioidosis presenting as native valve infective endocarditis with concomitant hepatic and splenic abscesses. This is the second case of melioidosis with infective endocarditis reported from India...

Infective endocarditis (IE) is an infection of the cardiac native or prosthetic valves typically caused by Staphylococcus aureus , viridans streptococci group, and coagulase-negative staphylococci. Risk factors include congenital heart disease, structural and valvular heart disease, implantation of prosthetic heart valves, and intravenous (IV) drug abuse. IE caused by organisms such as Burkholderia cepacia is rarely seen. We herein present a case of a patient with a history of IV drug abuse previously treated for Staphylococcus aureus IE with newly diagnosed IE secondary to B...

INTRODUCTION: Infective endocarditis (IE) is an important clinical condition with significant morbidity and mortality among the affected population. A single etiological agent is identifiable in more than 90 % of the cases, however, polymicrobial endocarditis (PE) is a rare find, with a poor clinical outcome. Here we report a case of native valve dual pathogen endocarditis caused by Burkholderia cepacia and Aspergillus flavus in an immunocompetent individual. It is among unique occurrences of simultaneous bacterial and fungal etiology in IE...

BACKGROUND: Burkholderia is a pathogen that is rarely seen in clinical cases. However, this organism is being found more commonly in hospitals. CASE PRESENTATION: A female Indonesian newborn was referred to our neonatal intensive care unit because of respiratory distress. The newborn had been delivered the previous night via cesarean section. A physical examination revealed intercostal retractions and weak cry. The newborn's gestational history was preterm, small for gestational age, and preterm premature ruptured membrane for 14 hours...

INTRODUCTION: Antibiotic overuse drives antibiotic resistance. The optimal duration of antibiotic therapy for Gram-negative bacteraemia (GNB), a common community and hospital-associated infection, remains unknown and unstudied via randomised controlled trials (RCTs). METHODS AND ANALYSIS: This investigator-initiated, multicentre, non-inferiority, informatics-based point-of-care RCT will randomly assign adult hospitalised patients receiving microbiologically efficacious antibiotic(s) for GNB to (1) 14 days of antibiotic therapy, (2) 7 days of therapy or (3) an individualised duration determined by clinical response and 75% reduction in peak C reactive protein (CRP) values...

Infective endocarditis is rarely caused by Burkholderia cepacia. Pseudomonas putidahas not been reported to cause infective endocarditis so far. This is the first case of infective endocarditis being reported, that is caused by Pseudomonas putidaand Burkholderia cepaciain an immunocompetent host with no predisposing factors. Aortic valve replacement surgery was carried out and antibiotics were given, to which the patient responded well and recovered.

Pseudomonas luteola which was previously known as Chryseomonas luteola; is a gram-negative, non-fermentative, aerobic, motile, non-spore-forming bacillus. It is frequently found as a saprophyte in soil, water and other damp environments and is an opportunistic pathogen in patients with underlying medical disorders or with indwelling catheters. It has been reported as an uncommon cause of bacteremia, sepsis, septic arthritis, meningitis, endocarditis, and peritonitis. Thus, early and accurate identification of this rare species is important for the treatment and also to provide information about the epidemiology of P...

BACKGROUND: Postmortem imaging (PMI) refers to the imaging of cadavers by computed tomography (CT) and/or magnetic resonance imaging (MRI). Three cases of cerebral infarctions that were not found during life but were newly recognized on PMI and were associated with severe systemic infections are presented. CASE PRESENTATIONS: An 81-year-old woman with a pacemaker and slightly impaired liver function presented with fever. Imaging suggested interstitial pneumonia and an iliopsoas abscess, and blood tests showed liver dysfunction and disseminated intravascular coagulation (DIC)...

OBJECTIVE: The aim of this study was to evaluate procalcitonin (PCT) diagnostic accuracy in discriminating gram-negative (GN) from gram-positive (GP) bloodstream infections and determining the relationship between PCT levels, infection sites, and pathogen types. METHODS: Clinical and laboratory data were collected from patients with blood culture (BC)-positive sepsis between January 2014 and December 2015. PCT levels at different infection sites were compared, as was the presence of GN and GP bloodstream infection...

The authors describe the case of a renal transplant patient who developed late infective endocarditis associated with an intracardiac fragment of a catheter inserted 16 years before. Clinical presentation was anemia of undetermined cause and weight loss. Three blood cultures were positive for Burkholderia cepacia. Transesophageal echocardiography revealed a foreign body in the right atrium and right ventricle, confirmed by computed tomography. The patient underwent intravenous antibiotic therapy, followed by cardiac surgery to remove the foreign body...

Burkholderia cepacia complex organisms are environmental Gram-negative bacteria which rarely cause disease in otherwise immunocompetent individuals. We describe a case of tricuspid valve endocarditis secondary to B. cepacia complex in an injecting intravenous drug user in Auckland, New Zealand.

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...

OBJECTIVE: To report the clinical characteristics of prosthetic valve endocarditis (PVE). METHODS: All 25 cases of definite PVE (Duke criteria) diagnosed at our hospital between January 1992 to December 2008 were retrospectively analyzed. Among them, 7 cases were pathologically confirmed and the others were clinically confirmed with either 2 major criteria or 1 major and ≥ 3 minor criteria. Their clinical characteristics, underlying heart diseases, previous heart operations, presenting manifestations, causative microbes, echocardiographic findings and prognosis, were studied...
