Chronic kidney disease (CKD) has become a major public health problem in Brazil and worldwide. There are many causes of CKD, being the congenital anomalies of the kidney and urinary tract and the glomerular diseases very common in pediatric patients, while diabetic nephropathy, CKD due to chronic arterial hypertension and glomerular diseases are predominant in adult patients. Many endogenous mediators have been related to the pathophysiology of CKD, being relevant the effects of the renin-angiotensin system (RAS) and the immune-inflammatory mediators including cytokines...

Parathyroid carcinoma is a very rare malignant tumor of the parathyroid gland. Clinically, this cancer is characterized by the presence of severe primary hyperparathyroidism. Diagnosis is based on histological examination but is not always easy. Surgery is the treatment of choice. We report the case of a 59-year old woman with a personal history of arterial hypertension and of recurrent renal lithiasis, presenting with diffuse bone pain associated with asthenia. Neck examination showed hard basi-cervical swelling with nonpalpable lower edge...

Nephron endowment, the total number of nephrons an individual is born with, is determined by both genetic and environmental factors during embryonic development. In 1988, Brenner hypothesized that there was an inverse relationship between nephron number and hypertension. Over the course of one's lifetime it is predicted that even healthy individuals will lose a significant percentage of nephrons as part of normal aging. Thus, a low nephron endowment at birth or in combination with age- or disease-related nephron loss could pre-dispose individuals to the development of hypertension...

BACKGROUND/AIMS: Although microangiopathic hemolysis (MAH) is a well-known complication of malignant phase hypertension (MPH), only less data on whether MAH in MPH predicts renal outcome exist. Therefore, we evaluated whether MAH was associated with the renal outcome in patients with MPH. METHODS: We conducted a single-center, retrospective, cohort study. Data from 35 patients diagnosed with MPH between October 1998 and January 2015 were analyzed. MPH was defined as the presence of a diastolic blood pressure of ≥120 mm Hg and grades III/IV hypertensive retinopathy according to the Keith-Wagener-Barker classification...

: European Society of Hypertension/European Society of Cardiology guidelines recommend calculation of estimated glomerular filtration rate and evaluation of urinary albumin excretion rate as routine tests in the initial evaluation and during the follow-up of all hypertensive patients. However, from a clinical point of view, renal ultrasound - a noninvasive, readily available and cheap imaging modality - could contribute to the better evaluation of a hypertensive patient by identifying common causes of secondary hypertension (HTN) originating from the kidney and more recently by detecting renal injury in severe or long-standing essential HTN by measuring renal resistive indexes...

BACKGROUND: Hypertension is one of the leading risk factors for cardiovascular, cerebrovascular, and renal disease. Its increasing prevalence and treatment costs influence the prescribing pattern among physicians. Drug utilization studies provide insights into the current prescribing practices and help us facilitate the rational use of drugs. We carried out the present study to assess the pattern of drug utilization in hypertensive patients. METHOD: Adults seeking treatment for hypertension were recruited...

INTRODUCTION: Hypertension is only controlled in approximately 35% of the patients, which could be partially due to non-adherence. Recently, bioanalytical assessment of adherence to blood pressure (BP) lowering drugs has gaining interest. Our aim was to explore possible determinants of non-adherence in treatment resistant hypertension, assessed by objective screening for antihypertensive agents in serum. Secondary aim was to study the effect of adherence on the change in BP. METHODS: This project was a sub-study of SYMPATHY; an open-label randomized-controlled trial to assess the effect of renal denervation on BP six months after treatment compared to usual care in patients with resistant hypertension...

Aortic dissection is the most catastrophic clinical condition that involves the aorta. It has a high mortality as well as high rate of misdiagnosis due to frequent unusual presentation. Typically, it presents with acute chest, back, and tearing abdominal pain. However, it can present atypically with minimal or no pain, making diagnosis difficult. Physicians should always suspect acute aortic dissection in patients with certain clinical conditions like difficult-to-control hypertension, giant cell arteritis, bicuspid aortic valve, intracranial aneurysms, simple renal cysts, family history of aortic disease, and Marfan syndrome, especially when a patient presents with ischemic symptoms involving multiple organ without an obvious cause...

Renal Artery Stenosis (RAS) is an important cause of treatment-resistant hypertension. Uncontrolled hypertension with RAS can cause progressive chronic kidney disease (CKD) leading to end-stage kidney disease. Therapeutic revascularisation can be helpful in appropriate circumstances where pharmaceutical intervention has failed and significant renovascular disease contributes to resistant hypertension. We present an interesting case of a Caucasian male with peripheral vasculopathy, abdominal aortic aneurysm (AAA), single functioning kidney and ostial RAS caused by stent struts from an endovascular AAA stent graft...

Augmented intratubular angiotensin (ANG) II is a key determinant of enhanced distal Na+ reabsorption via activation of epithelial Na+ channels (ENaC) and other transporters, which leads to the development of high blood pressure (BP). In ANGII-induced hypertension, there is increased expression of the prorenin receptor (PRR) in the collecting duct (CD), which has been implicated in the stimulation of the sodium transporters and resultant hypertension. The impact of PRR deletion along the nephron on BP regulation and Na+ handling remains controversial...

BACKGROUND: Hypertension is an important risk factor for adverse cardiovascular events including stroke, myocardial infarction, heart failure and renal failure. The main goal of treatment is to reduce these events. Systematic reviews have shown proven benefit of antihypertensive drug therapy in reducing cardiovascular morbidity and mortality but most of the evidence is in people 60 years of age and older. We wanted to know what the effects of therapy are in people 18 to 59 years of age...

Prenatal hypoxia is associated with growth restriction and adverse cardiovascular outcomes. Here, we describe renal and cardiovascular outcomes in ageing mouse offspring prenatally exposed to hypoxia (12% O2) from embryonic day 14.5 until birth. At 12 months of age, both male and female offspring exposed to prenatal hypoxia had elevated mean arterial pressure. Glomerular number was reduced by 25% in hypoxia-exposed male, but not female, offspring and this was associated with increased urinary albumin excretion, glomerular hypertrophy and renal fibrosis...

BACKGROUND: Diabetes has been reported to be associated with an increased relative risk for mortality, with estimates ranging from 1.1 to 2.1. Findings are inconsistent regarding modification of the risk by gender and by age. The aim of this study was to estimate the mortality risk associated with new-onset diabetes in adulthood, by age group and gender. METHODS: From the database of a large health care provider, we identified 31,987 individuals diagnosed with diabetes during 2003-2005; and 162,656 individuals without diabetes, group-matched by age...

Background: Renal denervation reduces blood pressure (BP) and sympathetic drive in experimental animal models, but the effect of this intervention on sympathetic activity in patients with treatment-resistant hypertension is still unclear. Methods: In an incident series of 29 patients with treatment-resistant hypertension, we performed serial measurements (n = 123) of muscle sympathetic nerve activity (MSNA, microneurography) and standardized BP measurements. Data were analysed by mixed linear modelling (MLM) and by regression analysis of time-integrated changes of both MSNA and synchronous, standardized (in-lab) BP measurements...

The present study reported a case of autosomal dominant polycystic kidney disease complicated with primary aldosteronism in a 49-year-old woman. The patient was referred for refractory hypertension. Laboratory examinations revealed low potassium and renin levels. Computed tomography indicated a right adrenal tumor and multiple renal cysts. Adrenal vein sampling revealed a high aldosterone level on the side of the tumor. The patient was diagnosed with autosomal dominant polycystic kidney disease complicated by primary aldosteronism and adrenalectomy was performed...

Angiotensin-converting enzyme-2 (ACE2) is downregulated in hypertensive nephropathy. The present study investigated the mechanisms whereby loss of ACE2 promoted angiotensin II-induced hypertensive nephropathy in ACE2 gene knockout mice. We found that compared with wild-type animals, mice lacking ACE2 developed much more severe hypertensive nephropathy in response to chronic angiotensin II infusion, including higher levels of blood pressure, urinary protein excretion, serum creatinine, and progressive renal fibrosis and inflammation...
