Filter by:To evaluate the gender-related elements, a first step will be to analyze the impact of sex ratio on different parameters such as age in endocarditis and the type of underlying valvulopathy and other associated comorbidities.
Infective endocarditis is a microbial infection of the endocardial surface of the heart.
Indocarditis is an endogenous infection acquired when organisms entering the blood stream establish on the heart valves, therefore, any bacteremia can potentially result in endocarditis. Infective endocarditis is an uncommon disease that often presents as pyrexia of unknown origin. The mortality rate in endocarditis was very high before the antibiotic era, even now a day, the mortality rate is around 20%(1).A variety of microorganisms can cause IE; staphylococci and streptococci account for the majority of cases. Staphylococcal IE is a common cause of healthcare-associated IE ; streptococcal IE is a common cause of community-acquired IE. Common bacterial pathogens include Staphylococcus aureus , Viridans group streptococci , Enterococcus, Coagulase-negative staphylococci , Streptococcus bovis , other streptococci , gram-negative bacteria, HACEK organisms in this category include a number of fastidious gram-negative bacilli: Haemophilus aphrophilus(subsequently called Aggregatibacter aphrophilus and Aggregatibacter paraphrophilus); Actinobacillus actinomycetemcomitans (subsequently called Aggregatibacter actinomycetemcomitans); Cardiobacterium hominis; Eikenella corrodens; and Kingella kingae , and fungi (1,2). A variable proportion of IE remain blood culture- negative (1-4). Most clinically significant bacteremias are detected within 48 hours; common and fastidious pathogens (such as members of the HACEK group) may be detected within five days of incubation with modern automated blood culture detection systems. The optimal volume of blood for each blood culture in adults is 20 ml. Zoonotic agents, such as Coxiella burnetii, Brucella spp., and Bartonella spp. were frequently detected in North Africa and identified as causes of infective endocarditis (IE) in Egypt (3,4).Blood culture is the most important investigation for diagnosing infective endocarditis andto know the prevalence rate of different bacteria and their antibiotic sensitivity pattern.Positive blood culture is the cornerstone of microbiological diagnosis of IE; three sets of blood cultures detect 96 to 98 percent of bacteremia. At least three sets of blood cultures should be obtained from separate venipuncture sites prior to initiation of antibiotic therapy. Patients with IE typically have continuous bacteremia; therefore, blood cultures may be collected at any time and need not necessarily be obtained at the time of fever or chills. MATERIAL and METHOD A total of 150 blood cultures were received from 50 clinically diagnosed cases of bacterial endocarditis . Blood sample was collected under all aseptic precautions.
Introduction. Comprehensive data on infective endocarditis in developing countries are scarce. Objectives: Description of the characteristics (clinical and microbiological) and assessment of the outcomes of infective endocarditis in low-income countries. Methods : Prospective, Observational, Multicentre study. Inclusion criteria: patients aged over 1 year fulfilling the modified Duke criteria for infective endocarditis. Exclusion criteria: patient included during a previous infective endocarditis episode. Outcomes measures: Mortality at 6 months follow-up; mortality at 1 month follow-up; access to antibiotic treatment (modalities and duration), hospital length of stay and reason for discharge, and cardiac surgery when indicated. Duration: One year (June 2014- June 2015)
The purpose is to evaluate autoantibodies in infective endocarditis patients before, at the beginning of treatment, and after the end of the treatment, and to correlate the autoantibodies in the presence of clinical symptoms.
The diagnosis of infective endocarditis is based on the results of blood culture and findings on transeosophageal echocardiography. Cardiac computarized tomography is a new modality, mainly used for the imaging of coronary arteries. Its use in the diagnosis of infective endocarditis is not well known.The purpose of this study is to establish the use of cardiac CT in infective endocarditis.
