Hypereosinophilic syndrome (HES) is a heterogeneous group of hematological disorders characterized by a chronic, unexplained hypereosinophilia with tissue damage. Cardiac involvement occurs in ∼20% of patients with HES and represents a major turning point. Cardiac injuries related to eosinophilia are divided into three chronological phases: eosinophilic infiltration, thrombosis, and fibrosis. We report a case of a 33-year-old woman diagnosed with HES, with pulmonary and gastrointestinal involvement and eosinophilic myocarditis in cardiogenic shock. The evolution was favorable with dobutamine, anticoagulation, corticosteroids, and later, β-blockers and angiotensin-converting enzyme inhibitors. Cardiac involvement in HES is rare but carries a poor prognosis. Corticosteroids are considered by many to be the mainstay of treatment. Although new treatments have been suggested, only a few seem promising.
L’endocardite infectieuse peut survenir sur un cœur sain ou pathologique. Parmi les cardiopathies à risque, on trouve les cardiopathies congénitales dont la CIV est la plus fréquente. Nous rapportons le cas d’une endocardite infectieuse à streptocoque oral, survenue sur une CIV non connue jusqu’à maintenant, chez un patient de 17 ans, se présentant sous forme de fièvre prolongée associée à une éruption cutanée. L’examen de la sphère ORL révéla par ailleurs des angines pseudomembraneuses avec un mauvais état buccodentaire. Les EI sur CIV sont les plus fréquentes des EI sur cardiopathie congénitale. Leur présentation clinique peut être atypique d’où le rôle primordial de l’échocardiographie. La prévention dans ces cas passe par une hygiène bucco-dentaire et cutanée optimale et non par une antibioprophylaxie.
Aortocardiac fistulae (ACF) are exceptionally due to infective endocarditis; they are usually congenital, posttraumatic, or complicate aortic dissection. In infective endocarditis setting, their presence should prompt urgent surgery as patients can deteriorate rapidly. We report the case of a 78-year-old female patient with the first ever reported quadricuspid aortic valve infective endocarditis complicated by multiple aortocardiac fistulae. Additionally, we provide a brief review of ACF, in infective endocarditis and quadricuspid aortic valve.
L'endocardite infectieuse est une urgence qui est diagnostiquée classiquement dans le cadre d'un syndrome infectieux associé à un souffle auscultatoire cardiaque. Elle peut mettre en jeu le pronostic vital via ses complications. Nous rapportons le cas d'une endocardite révélée suite à des manifestations neuro-abdominalesliées à un double anévrisme mycotiquesylvio-mésenterique et qui a bien évolué sous traitement medico-chirurgical.
Diabetes is a serious, frequent, and insidious morbidity and mortality risk factor in patients with coronary artery disease. It has been shown that carbohydrate metabolism disorders are common in acute coronary syndromes (ACSs): 30-40% of patients have diabetes, 25-36% have an intolerance to carbohydrates, and only 30-40% have a normal carbohydrate profile. Hyperglycemia occurring either in diabetic or nondiabetic patients is strongly associated with a poor prognosis. It increases the extent of myocardial necrosis, and the risk of recurrence acute coronary syndrome and hemodynamic complications, particularly heart failure and cardiogenic shock, reflecting the importance of optimal management of glucose metabolism abnormalities. The objective of this article is to suggest a screening and management guide for carbohydrate metabolism disorders during and in the immediate follow-up of ACS in diabetic and nondiabetic patients. Screening must be systematic in any patient admitted for ACS, and based on hemoglobin A1c and oral glucose tolerance testing. Treatment of hyperglycemia in the cardiology intensive care unit is recommended in any patient admitted with hyperglycemia >1.80 g/L or postfeeding blood glucose level >1.40 g/L, and should be based on intravenous insulin with concomitant infusion of glucose solution under strict monitoring. Once the patient is no longer in intensive care, intravenous insulin therapy is no longer recommended, and the passage to a fixed insulin therapy regimen or to oral antidiabetics should be considered in consultation with diabetologists. During the rehabilitation phase, good glycemic control improves both prognosis and survival.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
