Stroke is the second most frequent neurologic finding in postmortem studies of cancer patients. It has also been described as the first expression of an occult cancer. We have studied patients diagnosed with cancer after an ischemic stroke (IS) and we analyze differences with non-tumor patients. Single cohort longitudinal retrospective study of patients admitted to our center with IS diagnosis from 1 January 2012 to 12 December 2014. All patients were followed for 18 months. Patients with transient ischemic infarction or cerebral hemorrhage, active cancer or in the last 5 years, inability to follow-up or absence of complete complementary study (holter-EKG, echocardiogram, and dupplex/angiography-CT) were excluded...

A specific cause of anemia cannot be identified in many elderly patients. Erythropoiesis-stimulating agents (ESAs) may play a role in treating these patients with anemia of unknown etiology (AUE). This study examines hemoglobin and cardiovascular outcomes among elderly anemic patients treated with ESAs. We conducted a retrospective cohort study that included all anemic patients older than age 60 years who had erythropoietin (EPO) measured between 2005 and 2013 at a single center. Three independent reviewers used defined criteria to assign each patient's anemia to 1 of 4 groups: chronic kidney disease (CKD), myelodysplastic syndrome, AUE, or other etiology...

Renal fibrosis is the common outcome of many chronic kidney diseases (CKD) independent of the underlying etiology. Despite a host of promising experimental data, currently available strategies only ameliorate or delay the progression of CKD but do not reverse fibrosis. One of the major impediments of translating novel antifibrotic strategies from bench to bedside is due to the intricacies of the drug delivery process. In this review, we briefly describe mechanisms of renal fibrosis and methods of drug transfer into the kidney...

BACKGROUND: In pediatric chronic kidney disease (pCKD), traditional factors (proteinuria, etiology, and race) do not fully explain disease progression. The levels of methylated arginine derivatives (MADs: asymmetric and symmetric dimethylarginine, respectively) rise in CKD and increase with CKD progression. The impact of MADs on glomerular filtration rate (GFR) decline has not been examined in pCKD. The aim of this study was to examine the additive impact of baseline (BL) levels of MADs on directly measured GFR (mGFR) decline per year (ml/min/1...

In a new paradigm of etiology related to Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD) kidney injury may cause induction of factors in the injured kidney that are released into the circulation and thereby initiate and maintain renal fibrosis and CKD-MBD. Klotho is believed to ameliorate renal fibrosis and CKD-MBD, while ActivinA might have detrimental effects. The unilateral ureter obstruction (UUO) model is used here to examine this concept by investigating early changes related to renal fibrosis in obstructed kidney, untouched contralateral kidney and vasculature, which might be affected by secreted factors from the obstructed kidney, and compared to unilateral nephrectomized controls (UNX)...

BACKGROUND: Involvement of agrochemicals have been suggested in the development of chronic kidney disease of unknown etiology (CKDu). The association between CKDu and blood level of organochlorine pesticides (OCPs) in CKDu patients has been examined in the present study. METHODS: All the recruited study subjects (n = 300) were divided in three groups, namely, healthy control (n = 100), patients with chronic kidney disease of unknown etiology (n = 100), and patients with chronic kidney disease of known etiology (CKDk) (n = 100)...

Blood pressure control with renin-angiotensin system (RAS) blockade has remained the gold standard for treating patients with proteinuric chronic kidney disease (CKD) up to date. Nevertheless, RAS blockade slows but does not halt the progression of kidney disease, thus highlighting the need to search for additional therapeutic approaches. The nonselective phosphodiesterase (PDE) inhibitor pentoxifylline (PTX) is an old drug that exhibits prominent anti-inflammatory, anti-proliferative and anti-fibrotic activities both in vitro and in vivo...

Genome-wide association studies (GWASs) have identified many genetic risk factors for CKD. However, linking common variants to genes that are causal for CKD etiology remains challenging. By adapting self-transcribing active regulatory region sequencing, we evaluated the effect of genetic variation on DNA regulatory elements (DREs). Variants in linkage with the CKD-associated single-nucleotide polymorphism rs11959928 were shown to affect DRE function, illustrating that genes regulated by DREs colocalizing with CKD-associated variation can be dysregulated and therefore, considered as CKD candidate genes...

Long-term home parenteral nutrition (LTPN) in children with chronic intestinal failure (CIF) is associated with renal complications such as fluid and electrolyte imbalances, nephrocalcinosis, nephrolithiasis and chronic kidney disease (CKD). The etiology of CIF-associated nephropathy is multifactorial. The aim of this study was to evaluate renal involvement under LTPN. In this study 50 patients with CIF, median age 4.2 years (1.4 - 9.3, 23 female) were included. Kidney involvement was a frequent finding in this study...

Chronic kidney disease (CKD) is a global health problem with a genetic component. Genome-wide association studies have identified variants associated with specific CKD etiologies, but their genetic overlap has not been well studied. This study examined SNP associations across different CKD etiologies and CKD stages using data from 5,034 CKD patients of the German Chronic Kidney Disease study. In addition to confirming known associations, a systemic lupus erythematosus-associated risk variant at TNXB was also associated with CKD attributed to type 1 diabetes (p = 2...

Immunosuppression based on calcineurin inhibitors (CNIs) has greatly improved organ transplantation, although subsequent nephrotoxicity significantly hinders treatment success. There are no currently available specific soluble biomarkers for CNI-induced nephrotoxicity and diagnosis relies on renal biopsy, which is costly, invasive and may cause complications. Accordingly, identification of non-invasive biomarkers distinguishing CNI-induced kidney tubular damage from that of other etiologies would greatly improve diagnosis and enable more precise dosage adjustment...

Since first performed in 1954, kidney transplantation has evolved as the preferred long-term treatment of children with end stage renal disease (ESRD). The etiology of chronic kidney disease (CKD) and ESRD in children is broad and can be quite complicated, necessitating a multidisciplinary team to adequately care for these patients and their myriad needs. Precise surgical techniques and modern protocols for immunosuppression provide excellent long-term patient and graft survival. This article reviews the many etiologies of renal failure in the pediatric population focusing on those most commonly leading to the need for kidney transplantation...
