RESUMO
Hypereosinophilic syndrome is a rare entity and heterogeneous group of disorders characterized by hypereosinophilia and organ involvement. In this study, we presented a 49-year-old woman with cardiac tamponade in the context of Hypereosinophilic syndrome. Identifying hypereosinophilia as the underlying cause can have tremendous clinical implications for rapid initiation of appropriate treatment to minimize further end organ damage.

OBJECTIVES: Contrast-induced acute kidney injury (CI-AKI) is a serious complication in patients undergoing diagnostic cardiac angiography or percutaneous coronary intervention. We aimed to evaluate the preventive effects of left ventricular end-diastolic pressure (LVEDP)-guided hydration for the prevention of CI-AKI in patients with chronic kidney disease undergoing cardiac catheterization. METHODS: This prospective randomized single-blind clinical trial enrolled 114 eligible patients with an estimated glomerular filtration rate (eGFR) of 15 < eGFR ≤ 60 mL/min/1.73 m2 [according to the level-modified Modification of Diet in Renal Disease formula (MDRD)] and stable ischemic heart disease undergoing coronary procedures. The patients were randomly allocated 1:1 into the LVEDP-guided hydration group (n = 57) or the standard hydration group (n = 57). CI-AKI was defined as a greater than 25% or greater than 0.5 mg/dL (44.2 mmol/L) increase in the serum creatinine concentration compared with the baseline value. Hydration with 0.9% sodium chloride at a rate of 1 mL/kg/h (0.5 mL/kg/h if left ventricular ejection fraction < 40%) within 12 h was given to all the patients in both groups before the procedure. In the LVEDP-guided group, the hydration infusion rate was adjusted according to the LVEDP level during and after the procedure. RESULTS: The incidence of CI-AKI was 7.01% (4/57) in the LVEDP-guided group vs 3.84% (2/52) in the standard hydration group (summary odds ratio 0.53, 95% CI 0.093-3.022; P = 0.463). Major adverse cardiac events, hemodialysis, or related deaths occurred in neither of the groups during hospitalization or the 30-day follow-up. CONCLUSIONS: In the present study, LVEDP-guided fluid administration, by comparison with standard hydration, failed to offer protection against the risk of CI-AKI in patients with renal insufficiency undergoing coronary angiography with or without percutaneous coronary intervention.
