There are an estimated 14,000 randomized trials published in chronic kidney disease. The most frequently reported outcomes are biochemical endpoints, rather than clinical and patient-reported outcomes including cardiovascular disease, mortality, and quality of life. While many trials have focused on optimizing kidney health, the heterogeneity and uncertain relevance of outcomes reported across trials may limit their policy and practice impact. The international Standardized Outcomes in Nephrology (SONG) Initiative was formed to identify core outcomes that are critically important to patients and health professionals, to be reported consistently across trials. We convened a SONG Implementation Workshop to discuss the implementation of core outcomes. Eighty-two patients/caregivers and health professionals participated in plenary and breakout discussions. In this report, we summarize the findings of the workshop in two main themes: socializing the concept of core outcomes, and demonstrating feasibility and usability. We outline implementation strategies and pathways to be established through partnership with stakeholders, which may bolster acceptance and reporting of core outcomes in trials, and encourage their use by end-users such as guideline producers and policymakers to help improve patient-important outcomes.
S evere acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the cause of coronavirus disease 2019 (COVID-19), gains entry into target cells through the angiotensin-converting enzyme 2 (ACE2) receptors. ACE2 receptors are present in the kidneys as well as the lungs, heart, and intestinal cells. [1][2][3][4][5][6][7][8] The renin-angiotensin system plays an important role in human physiology. Angiotensin I is cleaved from angiotensinogen by renin and converted to angiotensin II by ACE. Angioten-REVIEW
SummaryBackground and objectives Octogenarians frequently require maintenance hemodialysis (HD) for treatment of stage renal disease ESRD. Although the Fistula First Initiative recommends creating an arteriovenous fistula as the preferred dialysis access method, vascular access selection should be based on life expectancy and functional status at treatment initiation. Results Thirty-seven octogenarian patients selected HD and two selected peritoneal dialysis. Among the 37 HD patients, 29 initiated dialysis with a tunneled cuffed catheter, 6 with an arteriovenous fistula, and 2 with an arteriovenous graft. Three patients regained renal function after an average 112 days and one was lost to follow-up. Of the 33 remaining on HD, 8 required nursing home admission and 25 were discharged home after initiating HD. Among these 33, 19 died and 14 remained on HD at the end of study period. Days on dialysis (mean Ϯ SEM) before death in those discharged to a nursing facility versus home were 52.6 Ϯ 14.7 versus 386.1 Ϯ 90.7 (P Ͻ 0.05), respectively.Conclusions Vascular access planning should include assessment of functional status and life expectancy in octogenarian HD patients.
Obesity increases circulating cell-endothelial cell interactions; an early marker of inflammation in laboratory model of sepsis, but little is known about the effect of different adipokines. Adiponectin is an anti-inflammatory adipokine secreted by adipocytes. Adiponectin deficiency is implicated in exaggerated proinflammatory phenotype in both obesity and sepsis via increased proinflammatory cytokine expression. However the effect of adiponectin deficiency on circulating cell-endothelial cell interactions in polymicrobial sepsis is unknown. Furthermore although brain dysfunction in septic patients is a known predictor of death, the pathophysiology involved is unknown. In the current study, we examined the effects of adiponectin deficiency on leukocyte (LA) and platelet adhesion (PA) in cerebral microcirculation of septic mice. Adiponectin deficient (Adipoq−/−: Adko) and background strain C57Bl/6 (wild type (WT)) mice were used. Sepsis was induced using cecal ligation and puncture (CLP). We studied LA and PA in the cerebral microcirculation using intravital fluorescent video microscopy (IVM), blood brain barrier (BBB) dysfunction using Evans Blue (EB) leakage method and E-selectin expression using dual radiolabeling technique in different WT and Adko mice with CLP. Adiponectin deficiency significantly exaggerated LA (WT-CLP:201 ± 17; Adko-CLP: ± 53 cells/mm2; P < 0.05) and PA (WT-CLP:125 ± 17; Adko-CLP:188 ± 20 cells/mm2; P < 0.05) in cerebral microcirculation, EB leakage (WT-CLP:10 ± 3.7; Adko-CLP:24 ± 4.3 ng/g × µl plasma; P < 0.05) and E-selectin expression (WT-CLP:0.06 ± 0.11; Adko-CLP:0.44 ± 0.053 ng/g; P < 0.05) in the brain tissue of the mice with CLP. Furthermore, E-selectin monoclonal antibody (mAb) treatment attenuated cell adhesion and BBB dysfunction of Adko-CLP mice. Adiponectin deficiency is associated with exaggerated leukocyte and PA in cerebral microcirculation of mice with CLP via modulation of E-selectin expression.
BackgroundObesity is a growing health issue in the Western world. Obesity, as part of the metabolic syndrome adds to the morbidity and mortality. The incidence of diabetes and hypertension, two primary etiological factors for chronic renal failure, is significantly higher with obesity. We report a case with morbid obesity whose renal function was stabilized with aggressive management of his obesity.Case reportA 43-year old morbidly obese Caucasian male was referred for evaluation of his chronic renal failure. He had been hypertensive with well controlled blood pressure with a body mass index of 46 and a baseline serum creatinine of 4.3 mg/dl (estimated glomerular filtration rate of 16 ml/min). He had failed all conservative attempts at weight reduction and hence was referred for a gastric by-pass surgery. Following the bariatric surgery he had approximately 90 lbs. weight loss over 8-months and his serum creatinine stabilized to 4.0 mg/dl.ConclusionObesity appears to be an independent risk factor for renal failure. Targeting obesity is beneficial not only for better control of hypertension and diabetes, but also possibly helps stabilization of chronic kidney failure.
Although rare, atypical hemolytic-uremic syndrome (aHUS) carries a high morbidity and mortality. Widespread microvascular thrombosis, thrombocytopenia and microangiopathic hemolytic anemia are the hallmark of aHUS. Virtually any organ (particularly the kidney) can be a target for the devastating effects of this syndrome. Uncontrolled activation of the alternative pathway of the complement system lies at the heart of the pathogenesis of aHUS. While significant advances have been made in our understanding of aHUS, establishing timely diagnosis of this syndrome has been challenging. This, in part, is due to the absence of a sensitive and specific diagnostic test and a relatively lack of our familiarity with the syndrome. With the recent success and approval of a humanized monoclonal antibody (eculizumab) in the treatment of aHUS, prompt and accurate diagnosis is of paramount importance to limit the target organ injury. This article presents a simplified approach to establishing the diagnosis of aHUS.
