Patients with chronic kidney disease (CKD) are at an increased risk of developing hyperkalemia, which can be potentially life threatening. Hyperkalemia is frequently encountered with renin-angiotensin-aldosterone system inhibitor (RAASi) therapy use in patients with CKD and often results in the underdosing or discontinuation of these drugs. RAASi therapy has been proven to delay the progression of CKD, ameliorate proteinuria, and reduce the overall risk of cardiovascular morbidity and mortality. Patiromer is a sodium-free, potassium-binding polymer used for the treatment of hyperkalemia. We present a case series of four patients with Stage 4 or 5 CKD in whom the initiation of dialysis was delayed with the use of patiromer. For one patient, dialysis was delayed by 18 months, whereas the remaining three patients, in whom hyperkalemia was one of the main complications, remain dialysis independent to date.

Nicotinamide adenine dinucleotide (NAD+) supplies energy for deoxidation and anti-inflammatory reactions fostering the production of adenosine triphosphate (ATP). The kidney is an essential regulator of body fluids through the excretion of numerous metabolites. Chronic kidney disease (CKD) leads to the accumulation of uremic toxins, which induces chronic inflammation. In this study, the role of NAD+ in kidney disease was investigated through the supplementation of nicotinamide (Nam), a precursor of NAD+, to an adenine-induced CKD mouse model. Nam supplementation reduced kidney inflammation and fibrosis and, therefore, prevented the progression of kidney disease. Notably, Nam supplementation also attenuated the accumulation of glycolysis and Krebs cycle metabolites that occurs in renal failure. These effects were due to increased NAD+ supply, which accelerated NAD+-consuming metabolic pathways. Our study suggests that Nam administration may be a novel therapeutic approach for CKD prevention.

Introduction: Approximately 50% of men diagnosed with prostate cancer will be exposed to androgen deprivation therapy (ADT) at some stage. The role of ADT in the management of metastatic disease has long been recognised, and its place in the management of localised and locally advanced disease has become clearer in the past few years. Nevertheless, concerns remain that some men might not benefit from ADT in earlier-stage disease. The purpose of the current article is to provide a brief narrative review of the role of ADT as part of a strategy of treatment with curative intent, concentrating mainly on key recent developments in the area. Methods: Narrative literature review of key publications in the English language relating to ADT in the management of localised and locally advanced prostate cancer. Results: In locally advanced and high-risk localised prostate cancer, the use of ADT in combination with radiotherapy improves disease-specific and overall survival. There is no evidence to support the use of ADT in the treatment of low-risk localised prostate cancer. There appears to be an increased risk of cardiovascular morbidity and mortality associated with luteinizing hormone-releasing hormone agonists, particularly in men with pre-existing cardiovascular disease, but the relevance of this in the adjuvant/neoadjuvant setting is currently unclear. Conclusions: Future studies should focus on identification of men who are at risk from cardiovascular complications associated with ADT and on the comparison of radiotherapy with ADT versus surgery in the management of localised and locally advanced prostate cancer, particularly with regards to men with pre-existing comorbidities.

ABSTRACT Dogs with protein-losing enteropathy (PLE) are suggested to be at increased risk of developing thromboembolic events. However, with some exceptions, there are very few reports of thromboembolism in such dogs. This multicentre retrospective observational study describes a case series of thromboembolism (TE) in eight dogs with PLE secondary to non-neoplastic, chronic small intestinal disease. Seven dogs had poorly controlled PLE when the thromboembolic event occurred. Pulmonary thromboembolism (PTE) occurred in six dogs, while one dog developed splenic vein thrombosis and another had concurrent splenic vein and aortic TE. Six dogs died, all with PTE. Antithrombin activity was decreased in one of two dogs in which it was measured. Serum cobalamin and folate concentrations were measured in three dogs and cobalamin was subnormal in all three. Serum magnesium, measured in two dogs, was low in both. Dogs with uncontrolled chronic small intestinal disease and PLE are at risk for developing serious life-threatening TE, mostly PTE.

Critically ill patients have conditions that are considered life-threatening and require comprehensive care and constant monitoring; nutritional support plays a key role in the recovery of these patients and is an area of veterinary medicine that is very easy for the registered veterinary nurse (RVN) to have an active role in. Critically ill patients are at increased risk of malnutrition; acute and chronic illness, trauma and inflammation induced stress-related catabolism, and drug-induced adverse effects may reduce appetite or increase nausea and vomiting. Challenges exist in the provision of support, especially in the anorexic patient. This article focuses on how severe physiological stress affects animals that are critically ill and how this might lead to malnutrition, how to accurately calculate energy requirements, and discusses the importance of selecting the most appropriate diet to improve patient outcomes.

Abstract Background Blood pressure (BP) control is critical in delaying the progression of chronic kidney disease (CKD), which otherwise results in an increased risk of cardiovascular morbidity and mortality. Angiotensin II receptor blockers (ARBs) or angiotensin-converting enzyme inhibitors, are recommended by several guidelines as first-line treatment for patients with hypertension and CKD. Purpose We reviewed and analysed the effect of ARB treatment on BP and renal outcomes (estimated glomerular filtration rate (eGFR), serum creatinine (SCr), creatinine clearance (CrCl) or proteinuria) in patients with hypertension and CKD with or without diabetes, including large clinical trials such as RENAAL and IDNT. Methods MEDLINE, EMBASE, and BIOSIS databases were searched for literature from the earliest available date to July 2017. Randomised (parallel-group) controlled trials of ≥8 weeks assessed the impact of ARBs on systolic/diastolic BP (SBP/DBP), eGFR, SCr, CrCl or proteinuria were included in the analysis. Meta-analysis (post- versus pre-treatment) and meta-regression were conducted in R-statistical software (v3.4.1) using meta- and metafor-packages. Mean difference (MD, generic inverse variance) with 95% confidence intervals (CIs) was used to pool data for an outcome in a single forest plot. The risk of bias (quality) of included studies was assessed by the six items of the Cochrane instrument. Results Of the 165 articles assessed for eligibility, 24 studies were included in the analysis (19 evaluated ARBs as monotherapy, 4 evaluated ARBs in combination with other antihypertensives and 1 evaluated ARBs both as mono- and combination therapy). Treatment with ARBs as monotherapy for ≥8 weeks to <1 year significantly reduced mean office SBP (MD, −12.60 mmHg; 95% CI, −18.53 to −6.67)/DBP (−6.52 mmHg; −11.27 to −1.77) (p<0.01). BP reduction was also significant (p<0.01) with ARB monotherapy for ≥1 year SBP (−14.84 mmHg; −17.82 to −11.85)/DBP (−10.27 mmHg; −12.26 to −8.27). ARBs also significantly reduced SBP/DBP when combined with other antihypertensive treatments for ≥8 weeks to <1 year as well as for ≥1 year (Figure). Moreover, ARBs induced significant reductions (p<0.01) in proteinuria (≥8 weeks to <1 year [MD, −0.6 g/L; 95% CI, −0.93 to −0.26; ≥1 year [−0.9 g/L; −1.22 to −0.59]), but no significant changes in eGFR, CrCl or SCr levels. The beneficial effect of ARBs was maintained overtime with no significant additional impact on SBP change (estimate: 0.025; 95% CI, –0.14 to 0.19) or eGFR (estimate: 0.068; 95% CI, −0.14 to 0.28; p=0.53). The overall risk of bias was judged to be low. Effect of ARBs on blood pressure changes Conclusion Treatment with ARBs effectively and sustainably lowered BP and proteinuria with no significant change in eGFR in patients with hypertension and CKD with or without diabetes.

Abstract Abstract 3344 Poster Board III-232 Background: Hepatic VOD is a life-threatening complication following SCT with a high incidence in children. Development of VOD is one of the most common causes of early death after SCT. Busulfan (BU), an alkylating agent with a very narrow therapeutic index is a commonly used conditioning agent in pediatric stem cell transplantation (SCT) with a strong correlation between AUC and both efficacy and toxicity. Oral BU (poBU) has significant age-related and interpatient pharmacokinetic differences and was linked with an increased risk for VOD. IV busulfan (ivBU) yielded promising results in some studies to be associated with low toxicity profile, especially with a reduced incidence of VOD. Methods: Patients <18 years with myeloablative SCT were included in a prospective multicenter phase II/III trial to evaluate the efficacy of Defibrotide (DF). Eligibility criteria included conditioning with BU (iv and po) and melphalan (MEL). Pts were prospectively randomized to the control arm or to receive DF. Primary endpoint was the incidence of hepatic VOD by D+30 using modified Seattle criteria (2 or more of the following: bilirubin > 2 mg/dL, hepatomegaly, ascites and/or unexplained weight gain > 5%). VOD was assessed by physical exam; hepatomegaly and ascites were confirmed by ultrasound. A blinded IRC of 3 expert hematologists confirmed the diagnosis of VOD. Although the study was not powered to assess mortality, a composite score was assessed as a secondary endpoint that incorporated VOD-associated toxicity (respiratory failure, renal failure, encephalopathy) and mortality. The additional analysis of the influence of BU on VOD was not planned and is therefore explorative. Results: 360 pts were enrolled between January 2006 and January 2009 by 28 centers in the EU and Israel. An Intent-to-Treat (ITT) analysis was performed on all pts who signed informed consent (n=356). 251 (71%) pts from the ITT population were conditioned with BU (64% ivBU; 36% poBU). 202 (55%) were treated with BU and Melphalan (MEL) (60% ivBU; 40% poBU). In 49 (14%) BU was used without MEL (80% ivBU; 20% poBU). In children <2yrs 44 (12%) were conditioned with BU/MEL (59% ivBU; 41% poBU) and 26 (7%) were conditioned without MEL (85% ivBU; 15% poBU). The median age of patients with iv BU was 3.65 yrs and 5,13 yrs with poBU; 28% infants, 50% children (ages 2-11 yrs) and 22% adolescents (evenly distributed). 45% female, 55% male (evenly distributed). Allo-SCT was performed in 69% with ivBU and 46% with poBU (remaining with auto-SCT). The diagnoses were evenly distributed between poBU and ivBU. Except in AML 18% were conditioned with ivBU and 32% with poBU. Preexisting liver disease was present in 23% ivBU and 9% poBU pts, of which 46% (17/37) ivBU and 37% (3/8) poBU had elevated transaminases. Overall VOD was experienced by 23% of the infants, 14% of the children and 13% of the adolescents. The overall incidence of VOD in pts treated with BU was 18%. VOD was diagnosed in 24% ivBU vs 8% poBU pts. In pts treated with BU/MEL VOD was diagnosed in 16%. VOD in ivBU/MEL was 21% (26) vs 8% (6) in poBU/MEL. In BU without MEL VOD was diagnosed in 27% (13/49). 31% (12/39) in ivBU pts and 10% (1/10) in poBU pts. In infants treated with BU/MEL the incidence of VOD in the ivBU group was 23% (6/26) and 11% (2/18) in poBU. In BU without MEL in infants the incidences were 41% (9/22) ivBU versus none (0/4) in poBU. The diagnosis of VOD independent of severity was associated with a higher mortality and equaled 24.6% (14/57) compared to 7% in pts without VOD (21/299). Respiratory failure was observed in 10% (16/161) of ivBU vs 2% (2/90) of poBU pts (9% (11/122) vs 1% (1/80) iv vs po BU/MEL); renal failure in 5% (8/161) ivBu vs 1% (1/90) poBU (5% (6/122) vs none in iv vs po BU/MEL). The incidence of multi-organ-failure (MOF) by day +100 was 12% (19/161) in ivBU vs 3% (3/90) in poBU (p=0.022). Compared to all other pts the risk to develop VOD in infants treated with allo-SCT and ivBU is 2.4 times higher (p=0.003). Conclusions: Although the scope of this trial was not to assess the influence of BU on the incidence of VOD and there was an imbalanced distribution of liver diseases and a potential bias for other risk factors the incidence of VOD in ivBU was unexpectedly high especially in infants. Inasmuch this is due to a high interpatient variability of the AUC should be explored prospectively. Disclosures: Corbacioglu: Gentium S.p.A.: Consultancy, Research Funding.

Nephropathy is a major microvascular complication of diabetes mellitus and often leads to terminal renal failure in addition to contributing significantly to cardiovascular morbidity and mortality. Despites continuous advances, the pathogenesis of diabetic nephropathy remains poorly understood. Recent studies have underscored the significance of structural and functional changes in podocytes in the development and progression of diabetic nephropathy. The role of podocytes in health and diabetic nephropathy and abnormalities including podocyte hypertrophy, effacement, and apoptosis, and a detailed discussion on the role played by the Wnt-β-catenin signaling pathway in podocyte injury and dysfunction are the focus of this review. In addition, the role played by Wnt signaling in mediating the effects of known therapeutic strategies for diabetic nephropathy is also discussed.

Amyloid angiopathy–associated intracerebral hemorrhage (ICH) comprises 12%–15% of lobar ICH in the elderly. This growing population has an increasing incidence of thrombolysis-related hemorrhages, causing the management of hemorrhages associated with cerebral amyloid angiopathy (CAA) to take center stage. A concise reference assimilating the pathology and management of this clinical entity does not exist. Amyloid angiopathy–associated hemorrhages are most often solitary, but the natural history often progresses to include multifocal and recurrent hemorrhages. Compared with other causes of ICH, patients with CAA-associated hemorrhages have a lower mortality rate but an increased risk of recurrence. Unlike hypertensive arteriolar hemorrhages that occur in penetrating subcortical vessels, CAA-associated hemorrhages are superficial in location due to preferential involvement of vessels in the cerebral cortex and meninges. This feature makes CAA-associated hemorrhages easier to access surgically. In this paper, the authors discuss 3 postulates regarding the pathogenesis of amyloid hemorrhages, as well as the established clinicopathological classification of amyloid angiopathy and CAA-associated ICH. Common inheritance patterns of familial CAA with hemorrhagic strokes are discussed along with the role of genetic screening in relatives of patients with CAA. The radiological characteristics of CAA are described with specific attention to CAA-associated microhemorrhages. The detection of these microhemorrhages may have important clinical implications on the administration of anticoagulation and antiplatelet therapy in patients with probable CAA. Poor patient outcome in CAA-associated ICH is associated with dementia, increasing age, hematoma volume and location, initial Glasgow Coma Scale score, and intraventricular extension. The surgical management strategies for amyloid hemorrhages are discussed with a review of published surgical case series and their outcomes with a special attention to postoperative hemorrhage.
