Libman-Sacks endocarditis is the most widely encountered aseptic endocarditis among patients with systemic lupus erythematosus. Due to the deformed cardiac valves, secondary infective endocarditis should be considered in lupus patients with acute refractory heart failure and fever of unknown origin. The case is reported of a woman with lupus and Libman-Sacks endocarditis who had concurrent coagulase-negative Staphylococcus infective endocarditis that resulted in cerebral septic emboli and acute pulmonary edema. She underwent valve replacement surgery for acute heart failure, and gradually recovered with antibiotic treatment.

Infective endocarditis is one of the leading causes of fever of unknown origin in those patients with intravascular catheters, prosthetic valves or cardiovascular implantable electronic devices. The diagnosis of infective endocarditis is made according to modified Duke criteria, which are based on blood culture and echocardiographic findings. Demonstration of vegetation with the transoesophageal echocardiography may be difficult in these cases with previous anatomical changes, especially in early phases. Positron emission tomography with (18)F-fluorodeoxyglucose ((18)F-FDG PET/CT) is well known to show an increased glucidic metabolism in malignant, inflammatory, and infectious processes. Thus, it provides useful functional imaging that enables the disease causing the fever of unknown origin to be detected well before structural changes are evident. Moreover, (18)F-FDG PET/CT helps to detect infectious extra-cardiac involvement, since the whole body is imaged with this technique. (18)F-FDG PET/CT may have an additional promising role for the monitoring of response to antimicrobial therapy in patients with established infective endocarditis, thus evaluating standard treatment outcome, as well as evaluating the need for alternative/intensified treatment options.

Bartonella henselae is a bacterium which can cause a wide range of clinical manifestations, ranging from fever of unknown origin to a potentially fatal endocarditis. We report a case of Bartonella henselae infection in a pediatric-aged patient following a scratch from a kitten. The patient initially presented with a prolonged fever of unknown origin which was unresponsive to antibiotic treatment. The patient was hospitalized with worsening fevers and night sweat. Subsequent ultrasound imaging demonstrated multiple hypoechoic foci within the spleen. A contrast-enhanced CT of the abdomen and pelvis was also obtained which showed hypoattenuating lesions in the spleen and bilateral kidneys. Bartonella henselae IgG and IgM titers were positive, consistent with an acute Bartonella henselae infection. The patient was discharged with a course of oral rifampin and trimethoprim-sulfamethoxazole, and all symptoms had resolved following two weeks of therapy.

Isolated pulmonary valve endocarditis is an extremely rare clinical condition. Here, we report a case of pulmonary valve endocarditis caused by methicillin-resistant Staphylococcus aureus (MRSA). An 84-year-old man with a history of aortic regurgitation and patent foramen ovale was admitted to our hospital due to fever of unknown origin for 4 weeks' duration. MRSA was detected in his blood cultures. Transthoracic echocardiography demonstrated a mobile vegetation attached to the pulmonary valve, moderate to severe aortic regurgitation, and patent foramen ovale with left-to-right shunt. After 30-days' treatment with vancomycin, gentamicin and rifampicin, he defervesced and blood cultures became negative. At surgery, a large vegetation was still attached to the pulmonary valve, but the leaflets remained with minimum damage. Aortic valve replacement, direct closure of the patent foramen ovale, and simple resection of the vegetation were performed. The postoperative course was uneventful.

Fungal endocarditis is a rare and fatal condition. The Candida and Aspergillus species are the two most common etiologic fungi found responsible for fungal endocarditis. Fever and changing heart murmur are the most common clinical manifestations. Some patients may have a fever of unknown origin as the onset symptom. The diagnosis of fungal endocarditis is challenging, and diagnosis of prosthetic valve fungal endocarditis is extremely difficult. The optimum antifungal therapy still remains debatable. Treating Candida endocarditis can be difficult because the Candida species can form biofilms on native and prosthetic heart valves. Combined treatment appears superior to monotherapy. Combination of antifungal therapy and surgical debridement might bring about better prognosis.

A 7-year-old female child presented with pyrexia of unknown origin. She had received an empirical regimen of antibiotic for possible endocarditis. Evaluation included multiple imaging supports and blood culture. She had left main coronary artery to right atrium coronary cameral fistula, restricted patent ductus arteriosus, vegetation at the right atrial exit of fistula and negative blood culture. Ongoing fever more than 2 weeks, oscillating vegetation in the echo and histopathological evidence of healing vegetation suggested definite diagnosis of infective endocarditis. She was treated successfully by surgical closure of fistula from the right atrial approach. Device closure in this case would have resulted in a large residual cul-de-sac with or without tiny residual high-velocity jets, either being a threat for future enlargement, rupture of the residual aneurysmal sac, thromboembolism, prolonged anticoagulation, and infective endocarditis.

A 9-year-old boy presented to the emergency department with blunt abdominal trauma. Initial assessment was normal except for abdominal tenderness. On day 3, patient was transferred to the pediatric intensive care unit (PICU) for hemodynamic instability, and persistent fever despite antibiotic therapy. On PICU admission, his body temperature was 40 0C, heart rate was 160/min, respiratory rate was 36/min, blood pressure was 85/40 mmHg, and impaired consciousness was noticed. Complete blood count revealed hemoglobin of 11.5 g/dl, white blood cell count of 22,500/mm3 and platelet count of 145,000/mm3. Serum C-reactive protein and procalcitonin were 139 mg/dl and 8.80 ng/ml, respectively. Renal and liver function test results were normal. Cranial magnetic resonance imaging (MRI) was planned because of impaired consciousness and fever. On cranial MRI, multiple infarct areas were detected in both hemispheres and minimal hemorrhagic focus was found in the left temporal region. Because of the cranial MRI findings and fever echocardiographic examination was planned to exclude infective endocarditis. Transthoracic echocardiography successfully visualized mitral valve prolapse, 14x8 mm mobile vegetation on the atrial side of the posterior leaflet of the mitral valve, and severe mitral regurgitation. The left chambers were dilated. There was no evidence of a perivalvular abscess. On control transthoracic echocardiography, after 6 weeks of parenteral antibiotic treatment, there was no significant reduction of the visible vegetation therefore surgery was planned. Infective endocarditis should be considered in the differential diagnosis of fever of unknown origin. Especially during the early stage of disease, cranial MRI may be more useful to prevent fatal complications for patients with neurologic examination findings.

Supravalvular aortic stenosis is a less common form of left ventricular outflow tract obstruction (LVOTO); commonest being the valvular aortic stenosis followed by valvular and subvalvular forms respectively. Most of the supravalvular aortic stenosis is associated with Williams syndrome; isolated supravalvular aortic stenosis is further rarer. We present a case of isolated SVAS with infective endocarditis (1.6) as the cause of pyrexia of unknown origin (PUO).

Numerous studies over past four decades have implicated a strong association of Streptoccus bovis infection with colorectal carcinomas. Strong is this association that a screening colonoscopy for identifying malignancy is considered mandatory in patients whose blood/fecal cultures show growth of this particular pathogen. Here, we report an interesting case of a 61-year-old female patient who presented with pyrexia of unknown origin for 3 weeks. Positron emission tomography/computed tomography, in addition to helping diagnose mitral valve endocarditis, also identified a clinically occult T2N0 rectal carcinoma.

Lactobacillus species are a commensal flora of the human gastrointestinal and the female genitourinary tract. Lactobacilli especially the rhamnosus species, are common components of commercial probiotics. They are rarely associated with pathology in immunocompetent people, but they have been known to cause dental caries, bacteremia, and endocarditis in patients with suppressed immune function. Cases of Lactobacillus bacteremia have been reported in patients with acute myeloid leukemia, large granular lymphocytic leukemia, and in transplant recipients. In this article, we report a strange case of recurrent Lactobacillus bacteremia causing multiple episodes of fever of unknown origin in a patient with leukemia. This report is unique as Lactobacillus is not recognized as a common source of bacteremia. Moreover, the source of the bacillus continued to elude us even after extensive investigation.
