BACKGROUND: In aging populations with an ever-growing burden of risk factors such as obesity, diabetes, and hypertension, chronic kidney disease (CKD) is on the rise. However, little is known about its exact prevalence among elderly adults, and often albuminuria is not included in the definition of CKD. Moreover, novel equations for the estimated glomerular filtration rate (eGFR) have recently emerged, which have not been applied comprehensively to older adults. Data on CKD awareness among the elderly are sparse...

Cytochrome P450-mediated metabolism of arachidonic acid (AA) is an important pathway for the formation of eicosanoids. The ω-hydroxylation of AA generates significant levels of 20-hydroxyeicosatetraenoic acid (20-HETE) in various tissues. In the current review, we discussed the role of 20-HETE in the kidney, liver, lung, and brain during physiological and pathophysiological states. Moreover, we discussed the role of 20-HETE in tumor formation, metabolic syndrome and diabetes. In the kidney, 20-HETE is involved in modulation of preglomerular vascular tone and tubular ion transport...

Left ventricular hypertrophy (LVH) is highly prevalent in kidney transplant recipients, and is associated with poor clinical outcome. Immunosuppressive agents might affect LVH behavior after kidney transplantation. This review is an appraisal of available data regarding LVH in renal transplantation and especially of studies that evaluated LVH response to treatment. In particular, the role of mammalian target of rapamycin inhibitors adopted as immunosuppressive agents in kidney transplantation is reviewed in the light of recent studies that have shown LVH regression induced by this class of medications in kidney transplant recipients with posttransplant cardiomyopathy...

Endothelin-1 (ET-1) promotes renal damage during cardiovascular disease; yet, the molecular mechanisms involved remain unknown. Endoplasmic reticulum (ER) stress, triggered by unfolded protein accumulation in the ER, contributes to apoptosis and organ injury. These studies aimed to determine whether the ET-1 system promotes renal ER stress development in response to tunicamycin. ETB deficient (ETB def) or transgenic control (TG-con) rats were used in the presence or absence of ETA receptor antagonism. Tunicamycin treatment similarly increased cortical ER stress markers in both rat genotypes; however, only ETB def rats showed a 14-24 fold increase from baseline for medullary GRP78, sXBP-1, and CHOP...

End-stage renal disease is frequently accompanied by cardiac comorbidity that warrants treatment with a cardiovascular implantable electronic device (permanent pacemaker or implantable cardioverter-defibrillator). In the United States, chronic hemodialysis (HD) population, cardiac implantable devices are present in up to 10.5% of patients; a venous HD catheter is utilized for blood access in 18% of prevalent patients. The concomitant presence of a venous HD catheter and cardiovascular implantable device creates a high-risk circumstance, with potential for causing symptomatic central venous stenosis, and for developing complicated endovascular infection...

PURPOSE: The purpose of this study is to perform a systematic review and meta-analysis on prevalence of frailty among patients with end-stage renal disease (ESRD). ESRD is associated with malnutrition, chronic inflammation, acidemia, impaired hormonal changes, and low physical activity, all of which can directly and indirectly contribute to the development of frailty. Coexistence of ESRD and frailty has been shown to increase risks of adverse health outcomes. Given potential reversibility of frailty, it is important to examine frailty status in this high-risk population...

Oral Antiplatelet Drugs (OAD) have a proven track record in the risk reduction of major cardiovascular events in patients with cardiovascular disease and normal kidney function. However, major gaps exist in our understanding of their effects on thrombosis and bleeding in chronic kidney disease (CKD). Clinical practice guidelines are ambiguous about use of such drugs in CKD patients, because patients with moderate to severe CKD were systematically excluded from clinical trials evaluating the efficacy and safety of OAD...

Gout is a well-known inflammatory arthritis and affects four percent of the United States population. It results from the deposition of uric acid crystals in joints, tendons, bursae, and other surrounding tissues. Prevalence of gout has increased in the recent decade. Gout is usually seen in conjunction with other chronic comorbid conditions like cardiac disease, metabolic syndrome, and renal disease. The diagnosis of this inflammatory arthritis is confirmed by visualization of monosodium urate (MSU) crystals in the synovial fluid...

We report a rare case of metastatic malignant solitary fibrous tumor (SFT) that presented with hypoglycemia because of insulin growth factor-2 production. Initial workup included computed tomography imaging that revealed a large, partially necrotic liver mass, a hypervascular pancreatic head lesion, and 2 renal lesions. Following hepatic resection, pancreatic head resection and nephrectomy, all these lesions demonstrated pathological findings that were consistent with SFT. The patient also had a history of an intracranial mass that had been previously resected and treated with gamma knife therapy at an outside institution, which was found to also be SFT...

Chronic kidney disease (CKD) is characterized by an irreversible decrease in kidney function and induction of various metabolic dysfunctions. Accumulated findings reveal that chronic hypoxic stress and endoplasmic reticulum (ER) stress are involved in a range of pathogenic conditions, including the progression of CKD. Because of the presence of an arteriovenous oxygen shunt, the kidney is thought to be susceptible to hypoxia. Chronic kidney hypoxia is induced by a number of pathogenic conditions, including renal ischemia, reduced peritubular capillary, and tubulointerstitial fibrosis...

Polyarteritis nodosa (PAN) is a necrotising vasculitis that involves medium and small vessels. PAN generally presents with constitutional, cutaneous, neurological, renal and gastrointestinal manifestations. However, PAN initially involving a single organ/system is uncommon. Here, we present a 42-year-old man who was hospitalised because of severe right upper quadrant abdominal pain that started 2 months before. Physical examination was remarkable for right upper quadrant abdominal tenderness. Abdominopelvic CT showed lymphadenopathy but no hepatic, gallbladder, pancreatic, intestinal or renal abnormalities...

We describe a patient with a 30-year history of mycosis fungoides (MF) and renal transplantation performed 3 years before he presented with an ulcerated tumour in the lumbosacral area. Biopsy revealed a lymphatic infiltrate of medium-sized, pleomorphic T cells expressing the gamma-delta T-cell receptor. Radiological staging and bone marrow biopsy revealed no extracutaneous involvement. Despite reduction in systemic immunosuppressants, total skin electron beam radiotherapy and systemic chemotherapy, the disease followed a highly aggressive course and the patient died 31 years after initial diagnosis of MF...
