CKD patients with low-grade proteinuria (LP) are common in nephrology clinics. However, prevalence, characteristics, and the competing risks of ESRD and death as the specific determinants, are still unknown. We analyzed epidemiological features of LP status in a prospective cohort of 2,340 patients with CKD stage III-V referred from ≥6 months in 40 nephrology clinics in Italy. LP status was defined as proteinuria <0.5 g/24h according to current KDIGO guidelines. Patients with higher proteinuria constituted the control group (CON)...

Background: The central nervous system plays a vital role in the development of hypertension, but the molecular regulatory mechanisms are not fully understood. This study aimed to explore signaling in the paraventricular nucleus (PVN) which might contribute to renal hypertension. Methods: Renal hypertension model was established by five-sixth nephrectomy operation (5/6Nx) in male Sprague Dawley rats. Ten weeks afterwards, they were random assigned to no treatment, or intracerebroventricular injection (ICV) with artificial cerebrospinal fluid, losartan [angiotensin II receptor type 1 (AT1R) antagonist], farnesylthiosalicylic acid (Ras inhibitor), PD98059 (MEK inhibitor), or SB203580 (p38 inhibitor) and Z-DEVD-FMK (caspase-3 inhibitor)...

BACKGROUND AND OBJECTIVES: Patients with chronic kidney disease (CKD) are often volume expanded and hypertensive. Few controlled studies have assessed the effects of a sodium-restricted diet (SRD) in CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted a randomized crossover trial to evaluate the effect of SRD (target <2 g sodium per day) versus usual diet on hydration status (by bioelectrical impedance spectroscopy) and blood pressure (BP) between May of 2009 and May of 2013...

Chronic kidney disease (CKD) affects up to 6% of women of childbearing age in high income countries, and is estimated to affect 3% of pregnant women. Advanced renal dysfunction, proteinuria, hypertension, and poorly controlled underlying primary renal disease are all significant risks for adverse maternal, fetal, and renal outcomes. In order to achieve the best outcomes, it is therefore of paramount importance that these pregnancies are planned, where possible, to allow the opportunity to counsel women and their partners in advance and to optimize these risks...

Obesity has become a worldwide epidemic, and its prevalence has been projected to grow by 40% in the next decade. This increasing prevalence has implications for the risks of diabetes, cardiovascular disease and also for Chronic Kidney Disease. A high body mass index is one of the strongest risk factors for new-onset Chronic Kidney Disease. In individuals affected by obesity, a series of complex pathophysiologic changes occur that lead to the development of Chronic Kidney Disease. These include on the one hand effects mediated by the downstream consequences of obesity (such as diabetes mellitus and hypertension), but also direct effects of adipose tissue, via humoral factors such as leptin, adiponectin, resistin and visfatin)...

Kidney involvement is an under-recognized complication of non-Hodgkin lymphomas. They occur in a variety of mechanisms and differ widely in their clinical presentation. We take this opportunity to report a case of a 65 year-old man who developed a rapidly progressive glomerulonephritis within days after completing his first cycle of R-CHOP (Rituximab, Cyclophosphamide, Doxorubicin, Vincristine, Prednisolone) chemotherapy for newly diagnosed mantle cell lymphoma. He was odematous, hypertensive, oliguric with nephrotic range proteinuria and an active urine sediment...

Renovascular stenosis is an important cause for arterial hypertension in childhood. We report a 10-month-old girl with arterial hypertension caused by right-sided renal artery stenosis detected by Doppler ultrasound. Magnetic resonance imaging (MRI) was performed before renal artery angioplasty to depict vascular anatomy in detail and to retrieve additional functional information of the kidneys by analysis of intravoxel incoherent motion (IVIM). The value of quantitative diffusion weighted imaging of the kidneys prior to percutaneous transluminal renal angioplasty (PTRA) is discussed...

OBJECTIVES: Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is accompanied by increased cardiovascular (CV) risk. Treatment of AAV patients includes the management of conventional CV risk factors, primarily hypertension and hypercholesterolemia, while lipoprotein(a) (LP(a)) is an emerging potential target. METHODS: We performed a multicenter, retrospective study in Germany. Patients were considered if they were between 18 and 90 years old and presented with AAV...

Aminopeptidase A (APA) is expressed in glomerular podocytes and tubular epithelia and metabolizes angiotensin II (AngII), a peptide known to promote glomerulosclerosis. In this study, we tested whether APA expression changes in response to progressive nephron loss or whether APA exerts a protective role against glomerular damage and during AngII-mediated hypertensive kidney injury. At advanced stages of FSGS, fawn-hooded hypertensive rat kidneys exhibited distinctly increased APA staining in areas of intact glomerular capillary loops...

BACKGROUND: The effect of gout on the risk of developing coronary artery disease (CAD) is uncertain. Some studies have found that gout is a risk factor for acute myocardial infarction. This study examined the changes in risk of CAD in gout patients taking allopurinol and/or benzbromarone, and analyzed the dose-response relationship of both drugs with CAD incidence. METHODS: The medical records of one million subjects from 2000 to 2011 were provided by the Taiwan National Health Insurance Research Database...

Marcel Ruzicka, Swapnil Hiremath
PURPOSE OF REVIEW: Release of the findings from the Systolic Blood Pressure Intervention Trial has resulted in a renewed examination of intensive blood pressure (BP) lowering. Only a few national hypertension guidelines (Canada and Australia) have changed recommendations, but considerable heterogeneity still exists with respect to the patient population to whom intensive BP lowering may apply. RECENT FINDINGS: There is fairly robust evidence that lower BP targets in nondiabetic chronic kidney disease (CKD) results in a decrease in heart failure and mortality...

OBJECTIVES: To assess whether moderate-to-severe CKD is a treatment modifier for benefit or harm in patients randomly allocated to 24-month versus 6-month DAPT. BACKGROUND: It is still unclear whether chronic kidney disease CKD should impact on the decision-making on optimal duration of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI). METHODS AND RESULTS: PRODIGY trial randomized 1970 all-comer patients at 24-month versus 6-month DAPT after PCI...

BACKGROUND: Growth pattern in early life is one of the most important factors affecting the pathogenesis of metabolic-associated diseases. The associations between serum uric acid (SUA) and hypertension, kidney disease, and coronary heart disease have been recognized. We investigated the association between increased BMI during childhood and adult SUA levels in Japan. METHODS: We included 298 children with health examination data between 1981 and 2002 who had also undergone physical examinations after reaching early adulthood (approximately 27 y old)...

End stage renal disease (ESRD) patients should be educated to maintain and preserve the arteriovenous fistula (AVF) in the best condition. The purpose of this work was to evaluate self-care frequency and factors that influenced such frequency. A prospective study was performed in 101 hemodialysis patients. Self-care behaviors were measured with the Scale of Assessment of Self-Care Behaviours with Arteriovenous Fistula in Hemodialysis. A regression model was used to determine the relevant predictors of self-care frequency and their influence...

Chronic kidney disease is defined by decreased glomerular filtration rate or proteinuria. Diabetic nephropathy and hypertensive renal damage are responsible for the majority of cases. The initiation of therapy has to consider if causal treatment of the underlying disease is possible and indicated. In all patients, even if specific treatment is not possible, therapy should aim at reducing progression of kidney failure. Chronic kidney diseases tend to intrinsic deterioration that persists after cessation of the causative damaging pathomechanism...

We previously reported that exogenous angiotensin (Ang) 1-7 has adverse cardiac effects in experimental kidney failure due to its action to increase cardiac angiotensin converting enzyme (ACE) activity. This study investigated if the addition of an ACE inhibitor (ACEi) to Ang 1-7 infusion would unmask any beneficial effects of Ang 1-7 on the heart in experimental kidney failure. Male Sprague-Dawley rats underwent subtotal nephrectomy (STNx) and were treated with vehicle, the ACEi ramipril (oral 1mg/kg/day), Ang 1-7 (subcutaneous 24 μg/kg/h) or dual therapy (all groups, n = 12)...
