Item Endocarditis-TR: Diagnosis, treatment, and prognosis of the infective endocarditispatients admitting tertiary centres of Turkey(2022) Calik, Ali Nazmi; Ozluk, Fatma Ozlem Arican; Karatas, Mehmet Baran; Canga, Yigit; Eren, Semih; Ayhan, Gorkem; Sunbul, Ayse; Palice, Ali; Candemir, Aytac; Akyuz, Sukru; Zoghi, Mehdi; Kozan, Omer; 36161622Background/aim: Infective endocarditis (IE) is still a significant cause of morbidity and mortality among cardiovascular diseases. ENDOCARDITIS-TR study aims to evaluate the compliance of the diagnostic and therapeutic methods being used in Turkey with current guidelines. Materials and methods: The ENDOCARDITIS-TR trial is a multicentre, prospective, observational study consisting of patients admitted to tertiary centres with a definite diagnose of IE. In addition to the demographic, clinical, microbiological, and echocardiographic findings of the patients, adverse events, indications for surgery, and in-hospital mortality were recorded during a 2-year time interval. Results: A total of 208 IE patients from 7 tertiary centres in Turkey were enrolled in the study. The study population included 125 (60.1%) native valve IE (NVE), 65 (31.3%) prosthetic IE (PVIE), and 18 (8.7%) intracardiac device-related IE (CDRIE). One hundred thirty-five patients (64.9%) were culture positive, and the most frequent pathogenic agent was methicillin-susceptible Staphylococcus aureus (MSSA) (18.3%). Among 155 (74.5%) patients with an indication for surgery, only 87 (56.1%) patients underwent surgery. The all-cause mortality rate was 29.3% in-hospital follow-up. Multivariable Cox regression analysis revealed that absence of surgery when indicated (HR: 3.29 95% CI: 0.93-11.64 p = 0.05), albumin level at admission (HR: 0.46 95% CI: 0.29-0.73 P < 0.01), abscess formation (HR: 2.11 95% CI: 1.01-4.38 p = 0.04) and systemic embolism (HR: 1.78 95% CI: 1.05-3.02 p = 0.03) were ascertained independent predictors of in-hospital all-cause mortality. Conclusion: The short-term results of the ENDOCARDITIS-TR trial showed the high frequency of staphylococcal IE, relatively high in-hospital mortality rates, shortage of surgical treatment despite guideline-based surgical indications and low usage of novel imaging techniques. The results of this study will provide a better insight to physicians in respect to their adherence to clinical practice guidelines.Item Comparative Evaluation of Cases with Community-Acquired Infective Endocarditis and Health Care-Associated Infective Endocarditis(2015) Kursun, Ebru; Turunc, Tuba; Demiroglu, Yusuf Ziya; Togan, Turhan; Tekin, Goknur; Arslan, HandePurpose: The present study aimed to comparatively evaluate the cases with health care-associated infective endocarditis and the cases with community-acquired infective endocarditis. Material and Methods: Of the cases followed for infective endocarditis (IE), 21 (40 %) had health care-associated infective endocarditis and 31 (60 %) community-acquired infective endocarditis. Results: Comparing the cases with community acquired infective endocarditis and the cases with health care-associated infective endocarditis, it was determined that advanced age (58.0 +/- 15.1 years vs. 41.3 +/- 14.4 years, P=0.000), presence of chronic renal insufficiency (P=0.001) and diabetes mellitus (P=0.016) as concomitant diseases, being previously hospitalized (P=0.0001), hemodialysis in terms of diagnostic and therapeutic interventions (P=0.022), presence of central venous catheter (P=0.022), and undergone intervention for gastrointestinal system (P=0.060), as well as laboratory results including positive blood culture growth for S. aureus and Enterococcus (P=0.037), and complications such as development of embolic event (P=0.008), spondylodiscitis (P=0.034) and stroke (P=0.007) were statistically significantly more common in health care-associated infective endocarditis cases. Whilst mortality was higher in health care-associated infective endocarditis cases (28.6 %), it was determined that there was no statistically significant difference between the groups. Conclusion: Health care-associated infective endocarditis is a disease that is more common in the patients at advanced age, with concomitant disease and the history of exposing invasive procedures in the past for diagnostic and therapeutic purpose, and it is a disease with high morbidity and mortality that courses with serious complications.Item Complicated left-sided infective endocarditis in chronic hemodialysis patients: a case report(2017) Gulmez, Oyku; Aydin, Mehtap; 0000-0002-9429-5430; 28106022; ABC-7134-2021; AAE-6201-2021Infective endocarditis (IE) is a serious infectious condition with high morbidity and mortality in patients with end-stage renal disease (ESRD). It has been particularly associated with recurrent bacteremia due to vascular access via lumen catheters. The most common pathogen is Staphylococcus (S.) aureus, and most affected valve is mitral valve, which frequently calcified. Two patients with ESRD who received hemodialysis treatment via tunneled catheters, aged 56 and 88 years, were admitted with fever and high troponin level. Blood cultures revealed growth of S. aureus. Good quality transthoracic echocardiography (TTE) displayed calcified mitral and aortic valves with no vegetation or abscess formation. Myocardial necrosis as result of catheter infection was considered. Both patients had persistent positive blood cultures 3 and 5 days after initiation of antibiotic treatment. Therefore, transesophageal echocardiogram (TEE) was scheduled. Results revealed perivalvular abscess in the older patient, and highly mobile vegetation in the younger patient. The older patient refused surgery and died soon after due to refractory shock. Mitral valve surgery was planned for the other patient; however, she developed left ventricular failure and bleeding, and also subsequently died as result of refractory shock. Patient evaluations were particularly unfavorable: they had catheter infection as primary focus, and TTE did not detect vegetation or annular abscess. Diagnosis of IE in patients with ESRD using Duke criteria is problematic; we have to keep use of TEE in mind to detect vegetation or abscess formation when there is clinical suspicion regarding ESRD patients even after good quality TTE.
