echocardiography and renal replacement therapy

Volume status, congestion, endothelial activation, and injury all play roles in glomerular filtration rate (GFR) decline. In this study, we aimed to determine whether the plasma endothelial and overhydration markers could serve as independent predictors for dialysis initiation in patients with chronic kidney disease (CKD) 3b-5 (GFR < 45 mL/min/1.72 m2 ) and preserved ejection fraction. A prospective, observational study in a single academic center was conducted from March 2019 to March 2022. Plasma levels of angiopoietin (Ang)-2, Vascular Endothelial Growth Factor-C (VEGF-C), Vascular Cell Adhesion Molecule-1 (VCAM-1), Copeptin (CPP), beta-trace protein (BTP), brain natriuretic peptide (BNP), and cardiac troponin I (cTnI) were all measured...

Infective endocarditis (IE) caused by methicillin-resistant Staphylococcus aureus (MRSA) is usually life threatening and difficult to treat. Contezolid is a newly approved oxazolidinone antimicrobial agent showing potent activity against MRSA. We successfully treated a case of refractory IE caused by MRSA with contezolid in a 41-year-old male patient. The patient was admitted due to recurrent fever and chills for more than 10 days. He had chronic renal failure for more than 10 years and under ongoing hemodialysis...

Myocarditis is challenging to diagnose because of its various clinical manifestations. Fulminant myocarditis (FM) is a severe type of myocarditis characterized by heart failure, malignant arrhythmia, cardiogenic shock, and cardiac arrest. Its early diagnosis and timely treatment are crucial for a positive long-term prognosis. Here we report a case of 42-year-old woman who presented with fever, chest pain, and cardiogenic shock. An initial examination showed increased myocardial enzyme levels and diffuse ST-segment elevation...

BACKGROUND: Chronic hemodialysis (HD) patients exhibit severe morpho-functional cardiac alterations, putting them at a high risk of death and adverse cardiovascular (CV) outcomes. Despite the fact that an unbalanced expression of various microRNAs (miRNAs) has been related to pathological cardiac remodeling and worse CV outcomes, scarce evidence exists on their role in this setting. METHODS: We evaluated circulating levels of a selected miRNAs panel (30a-5p, 23a-3p, 451a and let7d-5p) in 74 chronic HD patients together with a thorough clinical and echocardiography assessment...

BACKGROUND: The prognostic role of right ventricle dilatation and dysfunction (RVDD) has not been elucidated in patients with coronavirus disease (COVID)-related respiratory failure refractory to standard treatment needing extracorporeal membrane oxygenation (ECMO) support. AIM: To assess whether pre veno-venous (VV) ECMO RVDD were related to in-intensive care unit (ICU) mortality. METHODS: We enrolled 61 patients with COVID-related acute respiratory distress syndrome refractory to conventional treatment submitted to VV ECMO and consecutively admitted to our ICU (an ECMO referral center) from 31th March 2020 to 31th August 2021...

RATIONALE & OBJECTIVE: Heart-kidney crosstalk is recognized as the cardiorenal syndrome. We examined the association of cardiac function and structure with the risk of kidney failure with replacement therapy (KFRT) in a chronic kidney disease (CKD) population. STUDY DESIGN: Prospective observational cohort study. SETTING & PARTICIPANTS: 3,027 participants from the Chronic Renal Insufficiency Cohort Study. EXPOSURE: Five preselected variables that assess different aspects of cardiac structure and function: left ventricular mass index (LVMI), LV volume, left atrial (LA) area, peak tricuspid regurgitation (TR) velocity, and left ventricular ejection fraction (EF) as assessed by echocardiography...

BACKGROUND: Right ventricular (RV) function is increasingly being recognised as an important factor influencing outcomes in ST elevation myocardial infarction (STEMI) complicated by cardiogenic shock (CS). In this study, we investigated RV echocardiographic parameters' association with 28-day mortality in patients admitted to intensive care with STEMI complicated by CS with reduced left ventricle ejection fraction (LVEF). METHOD: We performed a retrospective analysis of patients admitted to intensive care unit (ICU) in a single tertiary cardiac centre over a 34-month period with STEMI complicated by CS and LVEF < 40%...

Cardiobacterium hominis ( C. hominis ) is a fastidious, pleomorphic, gram-negative bacillus that causes infective endocarditis. Identification of C. hominis is difficult because it grows very slowly in culture media. C. hominis is also known to cause large friable vegetations in the heart valves, complicated by systemic embolism. Here, we report a case of C. hominis infective endocarditis associated with cerebral, renal, and splenic infarctions. A 58-year-old Japanese man with a medical history of diabetes mellitus presented with acute right-sided back pain...

BACKGROUND: Hepatitis C virus (HCV) may play a pathogenic role in several forms of immune complex glomerulonephritis (GN). We present a patient whose initial clinical presentation instilled suspicion of HCV-related renal involvement. Yet, histopathologic data oriented towards a different diagnosis. CASE PRESENTATION: A 68-year old man presented with kidney dysfunction, cryoglobulins, low C4 level, high HCV-RNA and cutaneous vasculitis. The first hypothesis was a hepatitis C-related cryoglobulinemic glomerulonephritis...

OBJECTIVE: To investigate the effect of extracorporeal membrane oxygenation (ECMO) on in-hospital survival and prognosis of adult patients with fulminant myocarditis. METHODS: The registration materials of 21 patients with fulminant myocarditis supported by veno-arterial ECMO (VA-ECMO) from March 2019 to January 2022 in the Heart Center of the First Hospital of Lanzhou University were selected from the Chinese Society for Extracorporeal Life Support (CSECLS) Registry Database...

Fabry disease (FD) is a relatively rare X-linked hereditary disease caused by mutations in the GLA gene that results in deficient α-galactosidase A (α-Gal A) enzyme activity. The disturbed catabolism of the neutral sphingolipids globotriaosylceramide (Gb3) leads to its progressive lysosomal accumulation throughout the body. Multiple organs can be affected. The atypical late-onset cardiac variant is associated with a high burden of cardiac morbidity and mortality. The aim of this work was to present an updated overview of the FD, with focus on cardiovascular manifestations and its management...

Chronic kidney disease (CKD) is a risk factor for premature cardiovascular disease. As kidney function declines, the presence of left ventricular abnormalities increases such that by the time kidney replacement therapy is required with dialysis or kidney transplantation, more than two-thirds of patients have left ventricular hypertrophy. Historically, much research in nephrology has focussed on the structural and functional aspects of cardiac disease in CKD, particularly using echocardiography to describe these abnormalities...

BACKGROUND: The impact of etiologies of acute fulminant myocarditis (AFM), which requires extracorporeal membrane oxygenation (ECMO), on clinical outcomes remains unknown. This study aimed to investigate the risk factors for ECMO weaning and mortality among patients with AFM due to viral etiologies in a tertiary referral medical center. METHODS: We included 33 adults with AFM who received ECMO and were admitted between January 2002 and January 2021. General demographics, laboratory data, echocardiography findings, and long-term outcomes were analyzed for confirmed viral etiology and unconfirmed etiology groups...

BACKGROUND: Fabry disease (FD) is caused by a deficiency in the activity of the lysosomal enzyme, α-galactosidase A (α-Gal A), which leads to globotriaosylceramide (Gb3) deposition in multiple tissues. The current management of FD is enzyme replacement therapy (ERT). We report on the efficacy and safety of a new agalsidase beta, ISU303, in FD. METHODS: Ten patients (7 males, 3 females) were enrolled and administered a 1 mg/kg dose of ISU303, every other week for 6 months...

A 47-year-old previously healthy man was referred to a local hospital with chest tightness, oliguria, and lower extremity edema for seven days. An initial investigation revealed acute heart failure and kidney injury. The patient was intensively treated with cardiac and renal replacement therapy, and cardiorenal function improved one week later. Two months later, echocardiography was performed because chest tightness and edema had not resolved. Echocardiography showed Valsalva sinus rupture, and the patient was transferred to our center...

BACKGROUND: Fulminant myocarditis (FM) is a serious non-specific inflammatory disease of the myocardium. FM tends to occur in adolescents and the course of the disease progresses rapidly. It is prone to cardiogenic shock (CGS) and multiple organ failure (MOF) with high mortality. We report a case of FM with CGS and MOF in a young male who was successfully treated with intra-aortic balloon pump counterpulsation (IABP) combined with intravenous immunoglobulin (IVIG) and glucocorticoid (GC)...

A 62-year-old female was presented to the hospital of the current study for pancytopenia and was diagnosed with severe aplastic anemia. She was treated with a combination therapy of antithymocyte globulin, cyclosporine A, and eltrombopag. The patient also presented with febrile neutropenia after commencement of the treatment and did not respond to the various antibiotics and antifungal agents. Echocardiography showed a giant vegetation attached to the tricuspid valve on Day 78 of the immunosuppressive therapy, and the tricuspid valve replacement was performed...

OBJECTIVES: To examine the feasibility, efficacy, and safety of sustained low-efficiency dialysis (SLED) in hemodynamically unstable, critically ill children. METHODS: Critically ill patients, 1-18 y old with hemodynamic instability (≥ 1 vasoactive drugs) and severe acute kidney injury (AKI) requiring kidney replacement therapy (KRT) in a tertiary care pediatric intensive care unit were prospectively enrolled. Patients weighing ≤ 8 kg or with mean arterial pressure < 5th percentile despite > 3 vasoactive drugs, were excluded...

BACKGROUND: Cardiac dysfunction, a common complication of sepsis, is associated with increased mortality. However, its risk factors are poorly understood, and a predictive model might help in the management of cardiac dysfunction. METHODS: A monocentric prospective study of patients with sepsis was performed. Left ventricular global longitudinal strain (LV GLS) was measured using echocardiography within 72 h of the patients diagnosed with sepsis, and the patients were categorized into two groups: LV GLS > -17%, left ventricular systolic dysfunction group (LVSD group); and LV GLS ≤ -17%, non-left ventricular systolic dysfunction group (Non-LVSD group)...

OBJECTIVES: Type 2 diabetes (T2DM) is a common comorbidity in patients with degenerative aortic stenosis (AS).As a key item of the American Society of Thoracic Surgeons (STS) score, it has a vital impact on the clinical prognosis of traditional thoracic surgery. T2DM has an adverse effect on the morbidity and mortality of cardiovascular diseases. At the same time, studies have shown that T2DM are associated with myocardial hypertrophy and remodeling, decreased left ventricular function, and worsening heart failure symptoms in the AS patients...
