RESUMEN
BACKGROUND: Membranoproliferative glomerulonephritis is a rare entity which can be a result from autoimmune diseases, caused by various medications and infections. CASE PRESENTATION: We herein present the case of a 62-year-old male patient who presented with fatigue and was found to have severe anemia, impaired renal function, and nephrotic syndrome. A renal biopsy revealed membranoproliferative glomerulonephritis (MPGN) of the immune complex type with activation of the classical complement pathway. Further investigations led to the diagnosis of a chronic Coxiella burnetii-infection (Q fever), likely acquired during cycling trips in a region known for intensive sheep farming. Additionally, the patient was found to have a post endocarditic destructive bicuspid aortic valve caused by this pathogen. Treatment with hydroxychloroquine and doxycycline was administered for a duration of 24 months. The aortic valve was replaced successfully and the patient recovered completely. CONCLUSIONS: Early detection and targeted treatment of this life-threatening disease is crucial for complete recovery of the patient.

BACKGROUND: Isolated pulmonary valve endocarditis (IPE) accounts for less than 2% of all infective endocarditis patients. It is commonly associated with several predisposing factors, including intravenous drug use (IVDU) and congenital heart disease. The most common causative pathogens of IPE are Staphylococcus aureus and Streptococcus viridans. We report a Down's syndrome patient with IPE and with no standard risk factors caused by the rare pathogen Acinetobacter spp. This led to respiratory failure and systemic infection due to septic pulmonary emboli. Early elective surgery was decided upon as the patient was no longer responding to medical therapy, and his clinical condition was worsening over time. CASE PRESENTATION: A 15-year-old male with Down syndrome and no underlying heart defect presented with a 3-month history of episodic fever, nausea, vomiting, and diarrhea. Transthoracic echocardiography (TTE) revealed large vegetation on the pulmonary valve leaflet, another mobile mass at the pulmonary artery bifurcation, and severe pulmonary regurgitation. Serial blood cultures isolated Acinetobacter spp. Despite initial antibiotic therapy, the patient continued to have sepsis, unresolved vegetations, and developed life-threatening complications and respiratory distress, which convinced us to perform a pulmonary valve replacement surgery with a homograft. After surgery, the patient recovered and was discharged on the ninth postoperative day (POD). CONCLUSION: This report highlights IPE's diagnostic and therapeutic challenges, alongside the importance of a comprehensive cardiopulmonary workup in patients with unexplained fever, sepsis, and pulmonary symptoms, even without typical risk factors. Based on the patient's aggravating condition despite medical treatment, early surgical intervention and pulmonary valve replacement were deemed crucial. However, there still needs to be a definitive guideline on when and how surgery should be performed in patients with complicated IPE, especially in pediatric patients.

INTRODUCTION: Endocarditis associated with medical care is a rare and serious entity. The risk of occurrence is increased in hemodialysis patients due to the immunosuppression and the multiplicity of vascular accesses of different kinds. The mode of revelation can be variable given the diversity of symptoms it causes. Herein, we describe the case of endocarditis associated with medical care in a patient with renal failure who presents with neurological symptoms. OBSERVATION: A 38-year-old patient with a history of kidney disease in the hemodialysis stage presented to the emergency room with altered neurological status in the context of fever. The patient's condition requires airway control, sedation, and vasopressor medication. Brain imaging revealed Fisher 4 subarachnoid hemorrhage with brain turgor. Transthoracic and transesophageal cardiac ultrasound exploration revealed infective mitro-aortic endocarditis with trigonal abscess fistulized in the left ventricle and destruction of the aortic valve with massive regurgitation. The additional imaging in a second step did not highlight any images of mycotic aneurysm. The indication for early surgery was not approved given the hemodynamic instability and the poor intracerebral hemodynamics demonstrated by transcranial doppler ultrasound. The initial outcome under antibiotic treatment and renal replacement was favorable. But the subsequent course was fatal due to septic shock with multiple organ failure. CONCLUSION: The diagnosis of infective endocarditis should always be considered in hemodialysis patients presenting in a septic state with signs of systemic involvement. It is a source of mortality in these debilitated patients.

Multivalvular endocarditis is a rare and potentially fatal complication that can occur in people who inject drugs. Currently, there are few cases that have been studied or reported in literature. A complication of this manifestation that worsens prognosis and treatment is the distribution of septic emboli throughout the body which highlights the dissemination of the infection. There are no specific guidelines on the treatment of multivalvular endocarditis, but its complexity can present challenges in administering medical and surgical treatment. In this case of a 37-year-old man with infective endocarditis of 3 valves, a comprehensive work-up found septic emboli in the lungs, kidneys, ribs, spine, and brain with ophthalmologic involvement that resulted in visual impairment. This case highlights important complications that can occur with septic emboli and management of these issues using a multidisciplinary approach including the treatment of substance use disorder.

Fusobacterium nucleatum is a commensal pathogen typically found in the oral cavity, digestive tract, and urogenital system which has been associated with Lemierre's syndrome, periodontal diseases, sinusitis, endocarditis, and intra-abdominal and brain abscesses. Our case is of a 62-year-old male who presented with headaches, nausea, and vision loss. Brain imaging identified a right occipito-parietal brain abscess. Following surgery and abscess drainage, Fusobacterium nucleatum was isolated from intraoperative cultures, and the infectious disease service was consulted for antibiotic recommendations. Additional history uncovered that he had also been experiencing night sweats, generalized weakness and 40-pound weight loss for 2 months, and had a prior history of colon polyps and diverticulitis. Furthermore, the patient disclosed having substandard oral hygiene practices, particularly in relation to the care of his dental appliances. Despite negative blood cultures, suspicion for hematogenous seeding was high. Imaging ruled out periodontal disease, but identified a colovesical fistula and liver abscesses, indicating potential translocation of bacteria via portal circulation to his liver. Echocardiogram workup revealed a 1-cm mobile vegetation on the aortic valve. His course was complicated by breakthrough seizures, renal failure, and drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome, and he ultimately completed 16 weeks of antibiotics. This case illustrates an uncommon presentation of brain abscess in an immunocompetent adult, with a prior episode of diverticulitis as the probable primary infection source, leading to development of a colovesical fistula and bacterial dissemination to the liver, heart, and brain. It highlights the importance of a comprehensive diagnostic approach, including consideration of atypical pathogens in immunocompetent adults.

We encountered a rare case of infective endocarditis caused by a common Gram-positive anaerobic coccus Parvimonas micra, originating from colorectal cancer. The patient was a 78-year-old female, presented with fever, speech disorder, and right hemiplegia resulting from stroke. Transthoracic echocardiography revealed mitral regurgitation and a mobile vegetation on the mitral valve. Computed tomography( CT) of the abdomen revealed a mass lesion or abscess in the abdomen that was highly suggestive of relevance with infective endocarditis. An urgent surgery was initially performed to prevent further cerebral infarction, with abdominal surgery planned as the second stage. During the cardiac surgery, we observed a large defect following the partial resection of an infected posterior leaflet, and the adjacent calcified annulus was repaired using autologous pericardium. This effectively controlled mitral regurgitation. Both blood cultures yielded Parvimonas micra, which has recently become known as a biomarker for colorectal cancer. Subsequently, the patient's colorectal cancer was excised. Following the surgery, the patient was free from infection and underwent a rehabilitation program.

Whipple disease is a rare systemic illness associated with weight loss, diarrhea, and arthralgia. Asymptomatic carriage is common, but the disease can be complicated by cardiac involvement and may result in culture-negative endocarditis. Cardiac manifestations of the disease can lead to death. This report presents the case of a 66-year-old man with Whipple disease and biventricular heart failure with cardiogenic shock. Medical therapy followed by successful replacement of the aortic and mitral valves resulted in substantial improvement.

BACKGROUND: Klebsiella pneumoniae invasive syndrome (KPIS) is characterized by primary pyogenic liver abscess associated with metastatic infections. Although rare, Klebsiella endocarditis carries a high mortality risk. CASE PRESENTATION: A 60-year-old lady with type II diabetes mellitus presented with fever, malaise, right hypochondriac pain and vomiting for two weeks. Ultrasound abdomen revealed a collection within liver, and distended gallbladder with echogenic debris within. 3 days after ultrasound guided pigtail drainage of gallbladder empyema, newly presence murmur detected. Pus, urine, and blood cultures obtained were positive for Klebsiella pneumonia. Echocardiogram exhibited oscillating mass attached to anterior mitral valve leaflet. After 6 weeks of intravenous ceftriaxone, follow-up echocardiogram and ultrasound showed complete resolution of mitral valve vegetation, hepatic and gallbladder collection. CONCLUSION: Concomitant extrahepatic infective endocarditis (IE) should raise concerns in daily practice for patients with Klebsiella pneumoniae liver abscesses, despite the rarity of Klebsiella endocarditis. In the absence of diagnostic suspicion, antibiotic treatment regimens may be shortened, and adverse effects from IE infection may ensue.

OBJECTIVES: This study aimed to analyse the impact of preoperative septic cerebral embolism on early and late postoperative outcomes in patients with infective endocarditis undergoing valve surgery. METHODS: Retrospective multicentric study based on the Clinical Multicentric Project for Analysis of Infective Endocarditis in Germany (CAMPAIGN) registry comprising patients with infective endocarditis who underwent valve surgery between 1994 and 2018 at 6 German centres. Patients were divided into 2 groups for statistical comparison according to the presence or absence of preoperative septic cerebral embolism. Propensity score matching was performed for adjusted comparisons of postoperative outcomes. Primary outcomes were 30-day mortality and estimated 5-year survival. RESULTS: A total of 4917 patients were included in the analysis, 3909 (79.5%) patients without and 1008 (20.5%) patients with preoperative septic cerebral embolism. Patients with preoperative septic cerebral embolism had more baseline comorbidities. Mitral valve endocarditis (44.1% vs 33.0% P < 0.001), large vegetations >10 mm (43.1% vs 30.0%, P < 0.001), and Staphylococcus species infection (42.3% vs 21.3%, P < 0.001) were more frequent in the cerebral embolism group. Among patients with preoperative cerebral embolism, 286 (28.4%) patients had no stroke signs (silent stroke). After matching (1008 matched pairs), there was no statistically significant difference in 30-day mortality (20.1% vs 22.8%; P = 0.14) and 5-year survival (47.8% vs 49.1%; stratified log-rank P = 0.77) in patients with and without preoperative cerebral embolism, respectively. CONCLUSIONS: Preoperative septic cerebral embolism in patients with infective endocarditis requiring valve surgery does not negatively affect early or late mortality; therefore, it should not play a major role in deciding if surgery is to be performed.

A 66-year-old woman with liver cirrhosis and hemodialysis was referred with a 1-week history of pain and rash on the left lower leg. On an examination, the patient was in shock. She was administered catecholamine support for septic shock and ampicillin/sulbactam for severe cellulitis. Streptococcus dysgalactiae subsp. equisimilis (SDSE) was isolated from the blood culture, and she was diagnosed with streptococcal toxic shock syndrome. Despite therapy, the patient died on day 7 of admission. Infective endocarditis (IE) was diagnosed during an autopsy. Clinicians should be aware that overwhelming SDSE-IE can occur even in the absence of necrotizing fasciitis, especially in immunocompromised patients.

Non-ischemic papillary muscle rupture (PMR) is rare. PMR caused by myocarditis in the presence of concurrent infective endocarditis (IE) and myocardial infarction (MI) has not been described. We report a 46-year-old male with recurrent MRSA bacteremia who presented in septic shock and suffered cardiac arrest. Echocardiography revealed acute mitral valve regurgitation resulting from posteromedial PMR. An intra-aortic balloon pump was implanted. Angiography revealed thrombotic occlusion of a small distal left circumflex artery. Emergent mitral valve replacement surgery was performed. MRSA myocarditis and IE were diagnosed by tissue cultures. Coexistence of myocarditis, IE, and MI poses a challenge in determining etiology.

Polymicrobial endocarditis is uncommon, and polymicrobial endocarditis in combination with Coxiella burnetii is very rare. We herein describe an extremely rare case of polymicrobial bivalvular endocarditis due to coinfection with Enterococcus faecalis and Coxiella burnetii in a 62-year-old male patient, and extensively review the relevant medical literature. To the best of our knowledge, only three similar cases have been previously reported. Q fever is a worldwide endemic bacterial zoonosis, but it and its most common chronic complication, endocarditis, are still underestimated and underdiagnosed worldwide. This situation reflects the paucity of reported cases of polymicrobial endocarditis in combination with Coxiella burnetii. Clinical presentation of Q fever endocarditis is highly nonspecific, and diagnosis may be delayed or missed, leading to severe and potentially fatal disease. Our case and the previously reported similar cases emphasize the need for further evaluation of infective endocarditis due to Coxiella burnetii, in all cases of culture-negative endocarditis, and in prolonged oligo-symptomatic inflammatory syndrome, particularly in the presence of valvular heart disease. This approach should be applied even when typical pathogens are isolated, especially in endemic areas of Q fever, and with atypical presentation.

Infective endocarditis is a rare but life-threatening condition, occasionally linked to diverse immunologic manifestations, including mixed cryoglobulinemia. This can lead to cryoglobulinemic vasculitis, which has the potential for widespread organ damage. Although some cases have highlighted the relationship between infective endocarditis and cryoglobulinemic vasculitis, no comprehensive epidemiological evaluation or optimal treatment strategies have been advanced for such a combination. We present a case of methicillin-sensitive Staphylococcus aureus infective endocarditis associated with cryoglobulinemic vasculitis and conduct a literature review to compare management and outcomes in similar cases. Our patient presented with classical Meltzer's triad and mild renal involvement. Cryoimmunofixation confirmed type III cryoglobulinemia, and serum cytokines showed elevated IL-6 levels. The differential diagnosis included infective endocarditis and chronic active hepatitis C virus infection. Rapid symptom resolution after antibiotic treatment identified infective endocarditis as the likely cause of cryoglobulinemic vasculitis. Our case and review of the literature highlight that early identification of the cause of cryoglobulinemic vasculitis is crucial for selecting appropriate treatment and preventing recurrence or morbidity.

Infective endocarditis (IE) poses a diagnostic challenge due to its diverse clinical presentations, especially among high-risk groups. Diagnosis relies on integrating clinical presentation, blood cultures and imaging findings. Advanced imaging techniques enhance diagnostic accuracy, particularly in complex cases. Treatment involves antimicrobial therapy and surgery in complicated cases, with early intervention crucial for optimal outcomes. Coordinated care by an Endocarditis Team ensures tailored treatment plans, prompt complication management and long-term monitoring after discharge. The authors present a case of subacute IE presenting initially with back pain in a patient with a complex medical history, highlighting diagnostic and management approaches.

BACKGROUND: A fistulous tract in the mitro-aortic intervalvular fibrosa (MAIVF) is a rare entity, which presents as a complication of endocarditis or surgical trauma. Generally, it is associated to a pseudoaneurysm of the MAIVF (p-MAIVF) or aortic abscesses. MAIVF fistulas could potentially lead to devastating complications and a high mortality rate. This condition is managed surgically, either by a percutaneous closure or an open surgical approach. Herein we report the complex case of a patient with a MAIVF fistula secondary to bacterial endocarditis. Further clinical deterioration was caused by severe aortic valve insufficiency and hemodynamic compromise, requiring surgical intervention. CASE PRESENTATION: A 74-year-old male patient was admitted to a primary care center with complaints of malaise, asthenia, adynamia, hyporexia, and lower limb edema over the past eight days. His past medical history is positive for arterial hypertension and being monorenal. A transesophageal echocardiogram (TEE) was performed, exhibiting a 56% left ventricle ejection fraction (LVEF) and complicated aortic valve endocarditis. Surgical management through an open approach included vegetation resection, valve replacement, and closure of the MAIVF fistula. After completing antibiotic therapy, the patient was discharged without complications. During postoperative follow-up, the patient remained asymptomatic, and the control echocardiogram showed no signs of MAIVF fistula.4. CONCLUSIONS: The clinical case of a patient with a MAIVF fistula secondary to endocarditis by Streptococcus Anginous was presented. The fistulous tract was not associated to p-MAIVF or aortic abscess, findings which further deteriorate the patient's condition and increase the likelihood of fatality. This case reinforces the importance of a prompt diagnosis through cardiac imaging and timely surgical closure of the defect.

PURPOSE: S. aureus bacteremia (SAB) is a common and severe infection with high mortality and morbidity. The clinical relevance of the finding of concurrent S. aureus bacteriuria (SABU) is debated. The goal of this study was to analyze whether a concurrent SABU is associated with complicated SAB, infective endocarditis (IE) and mortality. METHODS: We conducted a retrospective cohort study, reviewing medical charts of all episodes of SAB in patients > 18 years in the region of Skåne, Sweden, between 1st of January and 31st of June 2020. Episodes where a concurrent urine culture was performed were included for analysis. An episode was considered as complicated SAB if there was either attributable mortality, recurrent infection, embolic stroke, or occurrence of a complicated focus of infection. RESULTS: During the study period, there were 279 episodes of SAB. 154 episodes met the eligibility criteria, of whom 37 (24%) had concurrent SABU. In 78 episodes (51%), the patients had a complicated SAB. There was a significantly lower proportion of complicated SAB for episodes with concurrent SABU (32%), compared to episodes without concurrent SABU (56%), p-value 0.014. Moreover, in the cohort there were 11 episodes (7.1%) of IE and a 30 days mortality rate of 16%, with no difference between the groups with or without SABU. CONCLUSIONS: There is an association between concurrent SABU and a decreased risk for complicated SAB among patients with SAB. This study found no significant association between SABU and neither IE nor mortality for patients with SAB.
