Hemolytic uremic syndrome (HUS) is one of the most common causes of acute renal failure in children. The majority of cases are associated with Shiga toxin (Stx)-producing Escherichia coli (STEC). In Argentina, HUS is endemic and presents the highest incidence rate in the world. STEC strains expressing Stx type 2 (Stx2) are responsible for the most severe cases of this pathology. Subtilase cytotoxin (SubAB) is another STEC virulence factor that may contribute to HUS pathogenesis. To date, neither a licensed vaccine nor effective therapy for HUS is available for humans...

TAFRO syndrome is a distinct idiopathic multicentric Castleman disease characterized by the association of thrombocytopenia, anasarca, fever, reticulin fibrosis, and organomegaly. We report the first case occurring in a Caucasian pregnant woman. At 34 weeks of gestation, our patient presented with all clinical and biological symptoms compatible with a TAFRO syndrome. Tough quick cesarean section was performed as symptoms got worse with onset of multiorgan failure requiring mechanical ventilation for acute respiratory distress, continuous renal replacement, and vasopressors...

BACKGROUND/INTRODUCTION: Risk stratification in chronic heart failure (HF) remains a challenge. Renal function and B-natriuretic peptide (BNP) might confer predictive value towards long-term mortality in HF patients after an acute coronary syndrome (ACS). METHODS: From May 2006 to March 2009, 1,000 consecutive patients who were hospitalized with ACS diagnosis were enrolled in the study. In 2016, the 10-year follow-up (2006-2016) was performed in 745 participants...

BACKGROUND: Tumor lysis syndrome (TLS) is a life-threatening disorder that occurs mainly in patients with high-tumor burden hemato-oncologic malignancies. It results in metabolic derangements, including hyperuricemia and acute renal failure. The powerful management for TLS is a daily dose of rasburicase for up to 5 days before chemotherapy; however, the optimal dose and duration of rasburicase for TLS prophylaxis have not been standardized for patients at high risk for TLS. Therefore, we evaluated the efficacy of single-dose rasburicase for prophylactic purposes in patients with malignant lymphoma at high risk for TLS...

There are only a few reports of successful use of mammalian target of rapamycin (mTORI) as primary immunosuppression in pediatric heart transplantation. Compared to calcineurin inhibitors, mTORI have less side effects, especially nephrotoxicity, infections and malignancies. A retrospective study was conducted at our institution of all 170 heart transplants from 1995-2015. Nineteen patients were switched from tacrolimus(n=15) or cyclosporin(n=4) to everolimus(n=4) or sirolimus(n=15) due to nephrotoxicity(n=5), malignancy(n=8), EBV viremia/reactive plasmacytic changes(n=5) and immune hemolytic anemia(n=1)...

A 24-year-old woman at 38 weeks of gestation with no past medical history was transferred to our hospital because of acute onset of severe dyspnea. Her conscious level was E4V2M5 on the Glasgow Coma Scale and she displayed stress cardiomyopathy (Takotsubo cardiomyopathy) with multiple organ failure. Intrauterine fetal death was confirmed. After immediate application of intubated ventilation, percutaneous cardiopulmonary support and hemodialysis, she was diagnosed with pheochromocytoma multisystem crisis. After multidisciplinary team discussion, surgical resection of the left pheochromocytoma was performed on the same day...

Kawasaki disease (KD) is an acute febrile vasculitis of an unknown cause. It affects children <5 year of age, even if cases over 5 years old have been also reported. It is the commonest cause of acquired heart diseases in children which may lead to serious morbidity and mortality. The complications and mortality increase when the diagnosis is delayed. One of the main reasons leading to delayed diagnosis and consequent delayed treatment is the unusual presentation of KD. Its unusual manifestations have been increasingly reported to jeopardize the timely diagnosis and proper treatment...

AIMS: Worsening renal function (WRF) occurs in one-third of patients hospitalized for acute decompensated heart failure. Recently, WRF was categorized in two subtypes: persistent and transient WRF. Thus, we sought to investigate the different prognostic impact of persistent vs. transient WRF; we also evaluate the relation of two WRF phenotypes with congestion, B-type natriuretic peptide (BNP) changes, and diuretic response at discharge. METHODS: The prospective was a single centre study including patients screened for interventional Diur-heart failure Trial (NCT01441245)...

BACKGROUND: Early revascularisation of the culprit lesion is the therapeutic cornerstone in cardiogenic shock complicating acute myocardial infarction. The optimal management of additional non-culprit lesions is unclear. This systematic review and meta-analysis aims to summarise current evidence on the comparison of immediate multivessel percutaneous coronary intervention (MV-PCI) or culprit lesion only PCI with possible staged revascularisation (C-PCI) in patients with cardiogenic shock complicating acute myocardial infarction...

BACKGROUND: Acute Atrial Fibrillation (AF) is common in critically ill patients, with significant morbidity and mortality; however, its incidence and severity in Intensive Care Units (ICUs) from low-income countries are poorly studied. Additionally, impact of vasoactive drugs on its incidence and severity is still not understood. This study aimed to assess epidemiology and risk factors for acute new-onset AF in critically ill adult patients and the role of vasoactive drugs. METHOD: Cohort performed in seven general ICUs (including cardiac surgery) in three cities in Paraná State (southern Brazil) for 45 days...

BACKGROUND: Nephrotoxicity is the major side effect in cisplatin chemotherapy. Previously, we reported that the ginsenosides Rk3 and Rh4 reduced cisplatin toxicity on porcine renal proximal epithelial tubular cells (LLC-PK1). Here, we aimed to evaluate the protective effect of ginsenosides Rk3 and Rh4 on kidney function and elucidate their antioxidant effect using in vitro and in vivo models of cisplatin-induced acute renal failure. METHODS: An enriched mixture of ginsenosides Rk3 and Rh4 (KG-KH; 49...

Tolvaptan, a vasopressin type 2 receptor antagonist, does not affect kidney circulation or cause worsening of renal function (WRF) in patients with acute decompensated heart failure (ADHF). Bioelectrical impedance analysis (BIA) can be used to evaluate intravascular volume by calculating the ratio of extracellular water (ECW) to intracellular water (ICW). There have been no reports examining the mechanisms of tolvaptan-induced diuresis using BIA. We investigated whether tolvaptan decreases excess volume while maintaining intravascular volume in ADHF patients...

Importance: Persistent congestion is associated with worse outcomes in acute heart failure (AHF). Mineralocorticoid receptor antagonists administered at high doses may relieve congestion, overcome diuretic resistance, and mitigate the effects of adverse neurohormonal activation in AHF. Objective: To assess the effect of high-dose spironolactone and usual care on N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels compared with usual care alone. Design, Setting, and Participants: This double-blind and placebo (or low-dose)-controlled randomized clinical trial was conducted in 22 US acute care hospitals among patients with AHF who were previously receiving no or low-dose (12...

BACKGROUND: Interventional catheterization procedures may be needed for patients with severe renal failure who are dependent on dialysis. To avoid the risk of fluid overload and electrolyte derangement during complex procedures in this oliguric/anuric patient population, we performed intra-procedural dialysis, either continuous renal replacement therapy (CRRT) or continous cycling peritoneal dialysis (CCPD). METHODS: We performed a retrospective review of a cohort of pediatric patients, ages 0-18 years, with dialysis-dependent renal failure who received CRRT or CCPD during catheterization procedures from January 2013 to March 2016...

Organ damage in sickle cell disease (SCD) is a crucial determinant for disease severity and prognosis. In a previous study, we analyzed the prevalence of SCD-related organ damage and complications in adult sickle cell patients. We now describe a seven-year follow-up of this cohort. All patients from the primary analysis in 2006 (n=104), were included for follow-up. Patients were screened for SCD-related organ damage and complications (microalbuminuria, renal failure, elevated tricuspid regurgitation flow velocity (TRV) (≥2...
