Heart and kidney failure continued to be of increasing prevalence in today's society, and their comorbidity has synergistic effect on the morbidity and mortality of patients. Cardiorenal syndrome (CRS) is a complex disease with multifactorial pathophysiology. Better understanding of this pathophysiological network is crucial for the successful intervention to prevent advancement of the disease process. One of the major factors in this process is neurohormonal activation, predominantly involving renin-angiotensin-aldosterone system (RAAS) and arginine vasopressin (AVP)...

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...

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...

Longstanding hypertension ultimately leads to heart failure (HF), and as a consequence most patients with HF have a history of hypertension. Conversely, absence of hypertension in middle age is associated with lower risks for incident HF across the remaining life course. Cardiac remodeling to a predominant pressure overload consists of diastolic dysfunction and concentric left ventricular (LV) hypertrophy. When pressure overload is sustained, diastolic dysfunction progresses, filling of the concentric remodeled LV decreases, and HF with preserved ejection fraction ensues...

BACKGROUND: The rate of Helicobacter pylori (H.pylori) eradication in dyspeptic patients using bismuth- based triple therapy is low due to bacterial that are resistant to antibiotics. The results of recent studies regarding levofloxacin have been encouraging, but the high cost of treatment prevents its routine administration. We, therefore, performed the present double-blind clinical trial to compare the efficiency of quadruple-drug regimen containing ofloxacin, clarithromycin, amoxicillin, and omeprazole and the same standard triple-therapy regimen minus ofloxacin in H...

BACKGROUND AND AIMS: Continuous venovenous hemofiltration or hemodiafiltration is used frequently in pediatric patients, but experience of continuous renal replacement therapy (CRRT) application on extracorporeal membrane oxygenation (ECMO) circuit is still limited. Among several methods used for applying CRRT on ECMO patients, we aim to share our experience on inclusion of a CRRT device in the ECMO circuit which we believe is easier and safer to apply. MATERIALS AND METHODS: The data were collected on demographics, outcomes, and details of the treatment of ECMO patients who had CRRT...

The introduction of direct-acting antivirals (DAA) has revolutionized the hepatitis C field. Most hepatitis C patients can now be cured, including those coinfected with HIV. However, drug-drug interactions (DDI) between DAA and antiretrovirals (ARV) should be known to prevent either toxicity due to drug overexposure or treatment failures due to low drug concentrations. Areas covered: Clinically significant DDI may be classified as major (when co-administration should be contraindicated) or minor (when they require close monitoring, changes in drug dosage or in timing)...

BACKGROUND: Fabry disease, an X-linked lysosomal storage disease, results from deficient α-galactosidase A (α-GalA) activity and the systemic accumulation of α-galactosyl-terminated glycosphingolipids. Two major phenotypes, "Classic" and "Later-Onset", lead to renal failure, and/or cardiac disease, and early demise. To date, the evolution and progression of the cardiac pathology and resultant clinical manifestations in family members of phenotype have not been well characterized. METHODS AND RESULTS: In a Classic family with nine affected members (GLA mutation c...

Renal transplantation is the best treatment for patients with end-stage renal disease. Over the last decades, the introduction of new immunosuppressive agents resulted into the reduction of the incidence of acute rejection and early graft loss. Despite this progress, there has been little improvement in the average life of the transplant. The main reasons of late failure are patient's death due to several complications (e.g. cancer, infectious or metabolic), and progressive deterioration of renal function caused by immunological and non-immunological factors...

Fabry's disease (FD) is a severe congenital metabolic disorder characterized by the deficient activity of lysosomal exoglycohydrolase alpha-galactosidase, characterized by glycosphingolipid deposition in several cells, such as capillary endothelial cells, renal, cardiac, and nerve cells. As a systemic disease leading to a contemporaneous myocardial and renal dysfunction, FD might be an example of cardiorenal syndrome type 5 (CRS-5). Kidney damage is commonly characterized by proteinuria, isosthenuria and altered tubular function when occurs at the second-third decade, azotemia and end-stage renal disease in third-fifth decade...

The beneficial effects of angiotensin converting enzyme (ACE) inhibitors and angiotensin II (AII) receptor antagonists in patients with heart failure secondary to reduced ejection fraction (HFrEF) are felt to result from prevention of the adverse effects of AII on systemic afterload and renal homeostasis. However, AII can activate the sympathetic nervous system and part of the beneficial effects of ACE inhibitors and AII antagonists may result from their ability to inhibit such activation. We examined the acute effects of the ACE inhibitor captopril (25 mg, n = 9) and the AII receptor antagonist losartan (50 mg, n = 10) on hemodynamics as well as total body and cardiac norepinephrine spillover in patients with chronic HFrEF...

Tubulointerstitial fibrosis is a common end point of chronic kidney diseases, and preventing its progression is key to avoiding renal failure. Transforming growth factor‑β (TGF‑β) and associated molecules promote tubulointerstitial fibrosis; however, effective therapies targeting these molecules have yet to be developed. Lysyl oxidase‑like 2 (LOXL2), which is involved in invasive growth and metastasis of malignant neoplasms, has recently been reported to serve a key role in hepatic and pulmonary fibrosis...

BACKGROUND Rhabdomyolysis is a syndrome caused by muscle breakdown. It can be caused by traumatic as well as non-traumatic factors such as drugs, toxins, and infections. Although it has been initially associated with only traumatic causes, non-traumatic causes now appear to be at least 5 times more frequent. In rhabdomyolysis, the CK levels can range anywhere from 10 000 to 200 000 or even higher. The higher the CK levels, the greater will be the renal damage and associated complications. We present the case of a patient with exceptionally massive rhabdomyolysis with unusually high CK levels (nearly 1 million) caused by combined etiologic factors and complicated with acute renal failure...

There may be cardio-renal interactions in rats of isoproterenol-induced heart failure, which may be associated with renal fibrosis and endothelial-to-mesenchymal transition (EndMT). Since its discovery, relaxin (RLX) which was regarded as a reproductive hormone for a long time, is recently considered an effective antifibrotic hormone in cardiac and renal fibrosis. We studied whether RLX diminished renal fibrosis in rats of isoproterenol (Iso)-induced heart failure and investigated the mechanism. Fifty male Sprague-Dawley rats were separated into five groups for treatment: control; Iso subcutaneously injection to induce heart failure, which led to renal fibrosis; RLX subcutaneously injection at low, medium and high dose (0...

BACKGROUND Risk adjustment is needed to fairly compare central-line-associated bloodstream infection (CLABSI) rates between hospitals. Until 2017, the Centers for Disease Control and Prevention (CDC) methodology adjusted CLABSI rates only by type of intensive care unit (ICU). The 2017 CDC models also adjust for hospital size and medical school affiliation. We hypothesized that risk adjustment would be improved by including patient demographics and comorbidities from electronically available hospital discharge codes...
