All patients treated with dual blockers at the start of the study (9 of 32) progressively withdrew the ACEI or ARA during the follow-up due to better blood pressure control and satisfactory proteinuria reduction after the introduction of the AA. In this respect, our data suggest that ACEI+AA or ARA+AA combinations could be an interesting alternative to dual ACEI+ARA blockers.</p><p id="par0125" class="elsevierStylePara elsevierViewall">Another fundamental issue is the beneficial effect of AA on cardiometabolic syndrome and resistant arterial hypertension in patients with obesity.

An important limitation of this study is that the formula used to calculate the GFR-MDRD-4 is not validated in the obese population. However, this study reproduces the standard clinical practice with significant fidelity. For this reason, more comparative studies are warranted to determine whether these antiproteinuric and renoprotective effects of AA are shared by other types of diuretics in the population with obesity, given that a number of studies have shown that thiazides can induce significant reductions in proteinuria when added to ACEIs and/or ARAs.<a class="elsevierStyleCrossRef" href="#bib0300"><span class="elsevierStyleSup">29</span></a> Similarly, sodium restriction boosts the antiproteinuric response to ACEIs and ARAs,<a class="elsevierStyleCrossRef" href="#bib0305"><span class="elsevierStyleSup">30</span></a> and the combination of hydrochlorothiazide with a low-sodium diet increases the response even further.<a class="elsevierStyleCrossRef" href="#bib0310"><span class="elsevierStyleSup">31</span></a></p><p id="par0135" class="elsevierStylePara elsevierViewall">In summary, the antiproteinuric effect and trend to slowing progression of renal failure with AA treatment in proteinuric nephropathies not changed by the condition of obesity. The renoprotective effect of aldosterone antagonists should be confirmed in larger prospective trials. The rational use of these drugs in adequate doses with close monitoring of side effects can combine their antiproteinuric effect and an adequate safety profile.</p></span><span id="sec0080" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0140">Conflict of interest</span><p id="par0140" class="elsevierStylePara elsevierViewall">The authors declare no conflict of interest.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:11 [ 0 => array:3 [ "identificador" => "xres590786" "titulo" => "Abstract" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "abst0005" "titulo" => "Introduction" ] 1 => array:2 [ "identificador" => "abst0010" "titulo" => "Material and methods" ] 2 => array:2 [ "identificador" => "abst0015" "titulo" => "Results" ] 3 => array:2 [ "identificador" => "abst0020" "titulo" => "Conclusion" ] ] ] 1 => array:2 [ "identificador" => "xpalclavsec606373" "titulo" => "Keywords" ] 2 => array:3 [ "identificador" => "xres590787" "titulo" => "Resumen" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "abst0025" "titulo" => "Introducción" ] 1 => array:2 [ "identificador" => "abst0030" "titulo" => "Material y métodos" ] 2 => array:2 [ "identificador" => "abst0035" "titulo" => "Resultados" ] 3 => array:2 [ "identificador" => "abst0040" "titulo" => "Conclusión" ] ] ] 3 => array:2 [ "identificador" => "xpalclavsec606374" "titulo" => "Palabras clave" ] 4 => array:2 [ "identificador" => "sec0005" "titulo" => "Introduction" ] 5 => array:3 [ "identificador" => "sec0010" "titulo" => "Material and methods" "secciones" => array:6 [ 0 => array:2 [ "identificador" => "sec0015" "titulo" => "Patients" ] 1 => array:2 [ "identificador" => "sec0020" "titulo" => "Therapeutic intervention" ] 2 => array:2 [ "identificador" => "sec0025" "titulo" => "Follow-up and data collection" ] 3 => array:2 [ "identificador" => "sec0030" "titulo" => "Study objectives" ] 4 => array:2 [ "identificador" => "sec0035" "titulo" => "Definitions" ] 5 => array:2 [ "identificador" => "sec0040" "titulo" => "Statistical analysis" ] ] ] 6 => array:3 [ "identificador" => "sec0045" "titulo" => "Results" "secciones" => array:5 [ 0 => array:2 [ "identificador" => "sec0050" "titulo" => "Patient characteristics" ] 1 => array:2 [ "identificador" => "sec0055" "titulo" => "Proteinuria" ] 2 => array:2 [ "identificador" => "sec0060" "titulo" => "Changes in renal function" ] 3 => array:2 [ "identificador" => "sec0065" "titulo" => "Changes in blood pressure and serum potassium levels" ] 4 => array:2 [ "identificador" => "sec0070" "titulo" => "Safety and tolerance of spironolactone" ] ] ] 7 => array:2 [ "identificador" => "sec0075" "titulo" => "Discussion" ] 8 => array:2 [ "identificador" => "sec0080" "titulo" => "Conflict of interest" ] 9 => array:2 [ "identificador" => "xack198755" "titulo" => "Acknowledgements" ] 10 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2014-12-06" "fechaAceptado" => "2015-04-13" "PalabrasClave" => array:2 [ "en" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Keywords" "identificador" => "xpalclavsec606373" "palabras" => array:4 [ 0 => "Obesity" 1 => "Aldosterone antagonist" 2 => "Proteinuria" 3 => "Nephropathy" ] ] ] "es" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Palabras clave" "identificador" => "xpalclavsec606374" "palabras" => array:4 [ 0 => "Obesidad" 1 => "Antagonista de la aldosterona" 2 => "Proteinuria" 3 => "Nefropatía" ] ] ] ] "tieneResumen" => true "resumen" => array:2 [ "en" => array:3 [ "titulo" => "Abstract" "resumen" => "<span id="abst0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0010">Introduction</span><p id="spar0005" class="elsevierStyleSimplePara elsevierViewall">Over the past decade, obesity has become a risk factor for developing chronic kidney disease.

La proteinuria está considerada un factor independiente de la progresión de la enfermedad renal crónica y el tejido adiposo se reconoce como una fuente de los componentes del sistema renina-angiotensina-aldosterona (SRAA). Estudios recientes han demostrado que los niveles de aldosterona plasmática son desproporcionadamente mayores en pacientes con obesidad. Los fármacos que bloquean el SRAA son incapaces de inhibir la aldosterona a largo plazo. El objetivo de nuestro estudio fue analizar el efecto protector a nivel renal de un antagonista de la aldosterona en combinación con bloqueadores del SRAA en pacientes con obesidad y nefropatía con proteinuria.</p></span> <span id="abst0030" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0040">Material y métodos</span><p id="spar0030" class="elsevierStyleSimplePara elsevierViewall">Este estudio es un subestudio del estudio publicado previamente sobre el efecto protector a nivel renal de los bloqueadores del receptor de mineralocorticoides en pacientes con nefropatías con proteinuria.
