COVID-19 y enfermedad cardiovascular y renal: ¿Dónde estamos? ¿Hacia dónde vamos?
2020
La pandemia SARS-CoV-2 es una emergencia sanitaria global y necesitamos conocer más sobre ella. Los pacientes con riesgo cardiovascular y renal previo se han identificado como especialmente vulnerables para una mayor morbimortalidad cuando sufren la COVID-19, y una proporción considerable de pacientes pueden desarrollar una lesión vascular en el contexto de la enfermedad que conlleva una mayor letalidad. Las complicaciones cardiovasculares y renales representan un problema, y es probable que en un futuro próximo puedan suponer una amenaza para los pacientes que han sobrevivido a la COVID-19. Como médicos no podemos olvidar que durante una epidemia como esta otras enfermedades ----crónicas--…
Diabetic Kidney Disease
2010
Diabetic nephropathy (DN) is the leading cause of chronic kidney disease and end-stage renal disease (ESRD). Patients with diabetic nephropathy have a high burden of cardiovascular morbidity and mortality. Therefore, interventions that reduce the incidence and progression rate of DN will reduce morbidity and mortality rates as well as health care costs. Hyperglycemia and arterial hypertension are the two main risk factors for DN, but even in the presence of hyperglycemia and elevated blood pressure (BP) for long periods, DN develops only in susceptible patients. Family studies have confirmed the presence of hereditary factors in the development of DN. Besides these four key factors, others …
Effects of exercise programs on physical function and activity levels in patients undergoing hemodialysis: a randomized controlled trial
2021
Background There are still many barriers when implementing exercise routines within daily dialysis care, even though benefits are well-known. Developing cost-effective strategies is necessary to overcome these barriers and include exercise as a complementary therapy in dialysis. Aim To compare several exercise programs on hemodialysis patient's functional capacity and health-related quality of life. Design This study was a 16-week follow-up, two-parallel group trial with balanced randomization. Setting Participants in this study belonged to a private hospitalized care center. Population Referred sample of 71 patients that suffered end-stage chronic kidney disease who underwent hemodialysis …
Early urinary sodium trajectory and risk of adverse outcomes in acute heart failure and renal dysfunction.
2021
Introduction and objectives: Urinary sodium (UNa+) has emerged as a useful biomarker of poor clinical outcomes in acute heart failure (AHF). Here, we sought to evaluate: a) the usefulness of a single early determination of UNa+ for predicting adverse outcomes in patients with AHF and renal dysfunction, and b) whether the change in UNa+ at 24 hours (Delta UNa24 h) adds any additional prognostic information over baseline values. Methods: This is a post-hoc analysis of a multicenter, open-label, randomized clinical trial (IMPROVE-HF) (ClinicalTrials.gov NCT02643147) that randomized 160 patients with AHF and renal dysfunction on admission to a) the standard diuretic strategy, or b) a carbohydra…
Acute kidney injury in heart failure: a population study
2020
Abstract Aims The objective of the present study is to assess the prognostic value of acute kidney injury (AKI) in the evolution of patients with heart failure (HF) using real‐world data. Methods and results Patients with a diagnosis of HF and with serial measurements of renal function collected throughout the study period were included. Estimated glomerular filtration rate (GFR) was calculated with the CKD‐EPI (Chronic Kidney Disease Epidemiology Collaboration). AKI was defined when a sudden drop in creatinine with posterior recovery was recorded. According to the Risk, Injury, Failure, Loss, and End‐Stage Renal Disease (RIFLE) scale, AKI severity was graded in three categories: risk [1.5‐…
The "Renocentric Theory" of Renal Resistive Index: Is It Time for a Copernican Revolution?
2020
Ultrasound (US) with duplex Doppler scanning has spread to the capillary level, becoming an irreplaceable tool in daily clinical practice thanks to its characteristics: low cost, repeatability, and noninvasiveness. Moreover, US has become over time more sensitive and accurate; it can be considered an extension of the clinician’s hand. For this reason, it currently represents the ideal tool for first-level diagnostic use in several fields, and is the simplest and most flexible instrument for obtaining morphological and functional information on different organs, including the kidneys. In this issue of The Journal , Gigante, et al 1 propose to assess renal involvement in patients with systemi…
Subclinical Kidney Damage in Hypertensive Patients: A Renal Window Opened on the Cardiovascular System. Focus on Microalbuminuria
2017
The kidney is one of the major target organs of hypertension. Kidney damage represents a frequent event in the course of hypertension and arterial hypertension is one of the leading causes of end-stage renal disease (ESRD). ESRD has long been recognized as a strong predictor of cardiovascular (CV) morbidity and mortality. However, over the past 20 years a large and consistent body of evidence has been produced suggesting that CV risk progressively increases as the estimated glomerular filtration rate (eGFR) declines and is already significantly elevated even in the earliest stages of renal damage. Data was supported by the very large collaborative metaanalysis of the Chronic Kidney Disease …
Identification of a plausible serum uric acid cut-off value as prognostic marker of stroke: the Uric Acid Right for Heart Health (URRAH) study
2021
The Working Group on Uric Acid and Cardiovascular Risk of the Italian Society of Hypertension conceived and designed an ad hoc study aimed at searching for prognostic cut-off values of serum uric acid (SUA) in predicting combined (fatal and non-fatal) cerebrovascular (CBV) events in the whole database. The URic acid Right for heArt Health study is a nationwide, multicenter, observational cohort study involving data on subjects aged 18-95 years recruited on a regional community basis from all the territory of Italy under the patronage of the Italian Society of Hypertension with a mean follow-up period of 120.7 ± 61.8 months. A total of 14,588 subjects were included in the analysis. A prognos…
A meta-analysis of the role of statins on renal outcomes in patients with chronic kidney disease. Is the duration of therapy important?
2013
article i nfo Introduction: The efficacy of statin treatment in chronic kidney disease (CKD) patients remains controversial. Therefore, we performed a meta-analysis to investigate whether statins modulate renal function in patients with CKD. Methods: Data from Scopus, PubMed, Web of Science, and the Cochrane Central Register of randomized controlled trials for years 1966-December 2012 were searched for appropriate studies. Results: Twenty trials with 6452 CKD subjects randomized to receive either statin or placebo were included. Statin therapy significantly influenced high sensitivity C-reactive protein levels in patients on or off dialysis (−0.28 mg/dl, 95%CI: −0.93 to −0.37; p b 0.05 and …
Expression of differentiation antigens and growth-related genes in normal kidney, autosomal dominant polycystic kidney disease, and renal cell carcin…
1992
Cellular differentiation and mRNA levels of genes involved in kidney growth were investigated in normal kidney cells, cyst-lining epithelial cells of polycystic kidney disease, and renal carcinoma cells (RCC). All cells comparatively studied exhibited an antigenic phenotype of proximal tubular cells as shown by the expression of a panel of brush border membrane enzymes and kidney-associated cell surface antigens. The epithelial developmental antigen Exo-1 was expressed in 50% to 80% of cyst-lining epithelia in polycystic kidney tissue and in 20% to 30% of polycystic kidney cells cultured in vitro. Normal kidney cells and RCC were negative under identical culture conditions. The expression o…
