RATIONAL: The inhibition of renin-angiotensin-aldosterone system (RAAS) is a major strategy for slowing the progression of chronic kidney disease (CKD). The utility of anti-RAAS agents in patients with congenital or acquired solitary kidney is still controversial. OBJECTIVE: A systematic literature review was conducted. MAIN FINDINGS: The conclusions of the few available studies on the topic are homogeneously in agreement with a long-term reno-protective activity of anti-RAAS drugs in patients with solitary kidney, especially if patients are hypertensive or proteinuric...

Current guidelines on hypertension treatment in chronic kidney disease (CKD) patients discourage combined angiotensin-converting enzyme inhibitor (ACEi) and angiotensin II receptor blocker (ARB) use due to the risk of an increased kidney function decline. However, dual compared to single renin-angiotensin system (RAS) blockade may have more efficacy with regard to hypertension and proteinuria. Among incident predialysis patients (CKD 4-5), we compared dual with no or single RAS blockade regarding kidney function decline and risk of renal replacement therapy (RRT) or death...

EDITORIAL
John Vincent
The focus of this edition of Clinical Pharmacolgoy & Therapeutics (CPT) is on drugs and renal function and will not include a detailed discussion of kidney disease and its treatment. It is well recognized that drugs affect the kidneys in different ways, while kidney disease impacts drug metabolism and response. It is impossible to underestimate the value of the kidneys to man in health and disease, from regulation of fluid and electrolyte balance to participating in drug metabolism and transport. Additionally, the kidneys serve as targets for drugs used to treat cardiovascular (CV) diseases including hypertension and heart failure, metabolic diseases such as diabetes mellitus and obesity, chronic kidney disease (CKD), as well as playing a role in the regulation of several hormones...

BACKGROUND: Continuous erythropoiesis receptor activator (CERA) is a newer, longer acting ESA which might be preferred to other ESAs (epoetin or darbepoetin) based on its lower frequency of administration. Different dosing requirements and molecular characteristics of CERA compared with other ESAs may lead to different health outcomes (mortality, cardiovascular events, quality of life) in people with anaemia and chronic kidney disease (CKD). OBJECTIVES: To assess benefits and harms of CERA compared with other epoetins (darbepoetin alfa and epoetin alfa or beta) or placebo/no treatment or CERA with differing strategy of administration for anaemia in individuals with CKD...

REVIEW

Uromodulin (also known as Tamm-Horsfall protein) is exclusively produced in the kidney and is the most abundant protein in normal urine. The function of uromodulin remains elusive, but the available data suggest that this protein might regulate salt transport, protect against urinary tract infection and kidney stones, and have roles in kidney injury and innate immunity. Interest in uromodulin was boosted by genetic studies that reported involvement of the UMOD gene, which encodes uromodulin, in a spectrum of rare and common kidney diseases...

BACKGROUND: In older adults (aged 70-74 years), African-Americans have 4-fold higher risk of developing hypertension-attributed end-stage renal disease (ESRD) than European-Americans. A hypothesized mechanism linking hypertension and progressive chronic kidney disease (CKD) is the innate immune response and inflammation. Persons with CKD are also more susceptible to infection. Gene expression in peripheral blood can provide a view of the innate immune activation profile. We aimed to identify differentially expressed genes, microRNAs, and pathways in peripheral blood between cases with CKD and high blood pressure under hypertension treatment versus controls without CKD and with controlled blood pressure in African Americans...

OBJECTIVE: Lithium is an essential mood disorder treatment; however, it remains unclear whether lithium increases chronic kidney disease (CKD) risk. There are few data on this in the elderly, even though older adults may be particularly susceptible to CKD. We wished to determine whether lithium is associated with increased CKD risk relative to valproate in older adults. METHODS: This nested case-control study analyzed province-wide administrative health data from mental health service users aged ≥ 66 years in Ontario, Canada, from 2003 to 2014...

REVIEW

The incidence of chronic kidney disease (CKD) is increasing worldwide, with more than 26 million people suffering from CKD in the United States alone. More patients with CKD die of cardiovascular complications than progress to dialysis. Over 80% of CKD patients have hypertension, which is associated with increased risk of cardiovascular morbidity and mortality. Another common, perhaps underappreciated, feature of CKD is an overactive sympathetic nervous system. This elevation in sympathetic nerve activity (SNA) not only contributes to hypertension but also plays a detrimental role in the progression of CKD independent of any increase in blood pressure...

BACKGROUND: Heart failure (HF) is associated with poor cardiac outcomes and mortality. It is not known whether HF leads to poor renal outcomes in patients with normal kidney function. We hypothesized that HF is associated with worse long-term renal outcomes. METHODS AND RESULTS: Among 3 570 865 US veterans with estimated glomerular filtration rate (eGFR) ≥60 mL min(-1) 1.73 m(-2) during October 1, 2004 to September 30, 2006, we identified 156 743 with an International Classification of Diseases, Ninth Revision, diagnosis of HF...

BACKGROUND: Management of chronic kidney disease (CKD) patients often requires the use of multiple drugs due to a high number of cardiovascular risk factors and complications associated with the disease. Multiple drugs predispose to potential drug-drug interactions (DDIs) which may be associated with increased morbidity, mortality, length of hospital stay and health-care cost. OBJECTIVES: This study determined the prevalence and pattern of potential DDIs among CKD patients attending Kidney Care Centre, in Ondo City, Nigeria...

Acute kidney injury (AKI) develops in up to 40% of patients after cardiac surgery. The soluble urokinase plasminogen activator receptor (suPAR) has been identified as a biomarker for incident chronic kidney disease (CKD). Proenkephalin (proENK) also has been shown to be a biomarker for renal dysfunction. We hypothesized that pre-surgery suPAR and proENK levels might predict AKI in patients undergoing cardiac surgery. Consecutive patients (n = 107) undergoing elective cardiac surgery were studied prospectively...

Elastin deficiency causes vascular stiffening, a leading risk for hypertension and chronic kidney disease (CKD). The mechanisms mediating hypertension and/or CKD pathogenesis due to elastin deficiency are poorly understood. Using the elastin heterozygous (Eln+/-) mouse model, we tested whether renal dysfunction due to elastin deficiency occurs independently of and precedes the development of hypertension. We assessed blood pressure and renal hemodynamics in 30-day and 12-week-old male and female mice. At P30, blood pressure of Eln+/- mice was similar to wild-type controls; however, renal blood flow was lower, whereas renal vascular resistance was augmented at baseline in Eln+/- mice...

Chronic kidney disease (CKD) is increasingly recognized in pregnant patients. Three characteristics are associated with a risk of preterm delivery or small for gestational age babies; kidney function reduction, hypertension, and proteinuria. In pregnancy, the anti-proteinuric agents (ACE-angiotensin converting enzyme-inhibitors or ARBS -angiotensin receptor blockers) have to be discontinued for their potential teratogenicity, and there is no validated approach to control proteinuria. Furthermore, proteinuria usually increases as an effect of therapeutic changes and pregnancy-induced hyperfiltration...

BACKGROUND: Hyperuricemia is associated with chronic kidney disease (CKD). Although topiroxostat, a novel, non-purine, selective xanthine oxidase inhibitor, has a strong effect against hyperuricemia, limited data are available on its renoprotective effect against CKD. METHODS: This study was conducted between October 2014 and May 2016. Thirty patients (20 male, 10 female) were administered 40 mg/day of topiroxostat twice daily. All patients were followed for a year...

Previous observational studies reported J or U-shaped associations between blood pressure parameters and mortality in patients with chronic kidney disease (CKD). Here we examined the associations of different blood pressure levels with various causes of death in a CKD population that included patients with eGFR 15-59 ml/min/1.73 m(2) with underlying hypertension receiving at least one antihypertensive agent. We obtained data on date and cause of death from State Department of Health mortality files and classified deaths into three categories: cardiovascular, malignancy-related, and non-cardiovascular/non-malignancy related...

BACKGROUND: Hypertension (HT) is the second leading cause of kidney failure. In hypertensive patients with chronic kidney disease (CKD), blood pressure (BP) control is the most important intervention to minimise progression. For CKD diagnosis, standardised creatinine and estimated glomerular filtration rate (eGFR) testing by CKD-EPI is recommended. OBJECTIVES: To describe the prevalence and factors associated with a moderate decrease in eGFR (by CKD-EPI) and BP control in subjects with HT...

CKD, diabetes and cardiovascular disease constitute three interrelated conditions of strong public health relevance. Elderly individuals account for the largest and the most rapidly growing age segment of the ESRD population. The elderly are affected by the same types of kidney diseases as younger individuals, but aging itself is associated with a gradual reduction in eGFR, which leads to the diminishment of the functional reserve and makes an individual more vulnerable to injurious effects of hypertension, cardiovascular disease, diabetes, and drugs' toxicity...

BACKGROUND: The effect of anemia on patients with ST-segment elevation myocardial infarction (STEMI) remains a controversial issue. The aim of this study was to explore the effect of anemia on STEMI patients. METHODS AND RESULTS: From January 2005 to December 2014, 1751 patients experienced STEMI checked serum hemoglobin initially before any administration of fluids or IV medications. 1751 patients then received primary percutaneous intervention immediately. A total of 1388 patients were enrolled in the non-anemia group because their serum hemoglobin level was more than 13 g/L in males, and 12 g/L in females...
