The methods used, such as mass spectrometry and the use of lectin-dependent antibodies (Helix aspersa agglutinin) for their reactivity, are difficult to carry out and are not available in many research and healthcare centers. In 2015, Yasutake et al. developed a monoclonal antibody KM55 that does not depend on lectin and that makes the measurement of Gd-IgA1, both circulating and on tissue, easier and more reproducible.<a class="elsevierStyleCrossRef" href="#bib0110"><span class="elsevierStyleSup">22</span></a> Previous studies with this antibody in patients with IgAN have shown that circulating Gd-IgA1 is related to histological findings, glomerular Gd-IgA1 deposition, and renal function and proteinuria at the time of biopsy, although not consistently.<a class="elsevierStyleCrossRefs" href="#bib0115"><span class="elsevierStyleSup">23–26</span></a> No studies have been conducted that relate the measurement of Gd-IgA1 by this method with the evolution of long-term renal function in a non-Asian population.</p><p id="par0015" class="elsevierStylePara elsevierViewall">On the other hand, it is known that the proliferation inducing ligand ("<span class="elsevierStyleItalic">A Proliferation Inducing Ligand</span>", APRIL) participates in the pathogenesis of NIgA by increasing the production of Gd-IgA1 in the mucosa.<a class="elsevierStyleCrossRefs" href="#bib0135"><span class="elsevierStyleSup">27,28</span></a> The aim of our study was to analyze the relationship between circulating Gd-IgA1 and APRIL in humans at the time of the diagnostic biopsy of IgAN and its influence on the long-term progression of nephropathy.</p></span><span id="sec0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0070">Material and method</span><p id="par0020" class="elsevierStylePara elsevierViewall">Renal biopsies performed between 1990 and 2019 diagnosed with IgA nephropathy classified with the Oxford criteria were retrospectively selected, from which a sample of serum extracted and frozen was available before the biopsy and before starting immunosuppressive treatment and with complete monitoring of the patient throughout their evolution. As a comparison group, the kidney biopsies performed between March/2015 and December/2018 were selected for suspected glomerular process (11 focal and segmental hyalinosis, five interstitial nephritis, four membranous GN, four RPGN, three TMA, three amyloidosis, two membranoproliferative, two diabetic nephropathy, two nephroangiosclerosis and one postinfectious GN). Those biopsies for which serum was not available before the biopsy, and also those with a diagnosis of lupus nephritis were excluded because it was a possible confounding factor when analyzing the Gd-IgA and APRIL values. No patient received immunosuppressive treatment before the biopsy. Healthy patients were not included as a second control group. Gd-IgA1 was measured by lectin-independent ELISA with monoclonal antibody KM55 (IgA1 kit Cat. No. 30111694. IBL Int., Hamburg, Germany).

Stage 5 CKD was defined when patients achieved a glomerular filtration rate below 15<span class="elsevierStyleHsp" style=""></span>mL/min, started dialysis, or underwent transplantation. The moment when the glomerular filtration rate dropped below 30<span class="elsevierStyleHsp" style=""></span>mL/min was also recorded.

If this relationship is confirmed in larger studies, it should be incorporated into the rest of the available predictive tools, since the current trend to detect those patients with a worse prognosis in this entity is to associate different clinical, analytical and pathological markers in a unique predictive tool.</p></span></span><span id="sec0070" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0130">Conflict of interests</span><p id="par0110" class="elsevierStylePara elsevierViewall">The authors declare that they have no conflict of interest.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:10 [ 0 => array:3 [ "identificador" => "xres1574107" "titulo" => "Abstract" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "abst0005" "titulo" => "Background and objective" ] 1 => array:2 [ "identificador" => "abst0010" "titulo" => "Materials and methods" ] 2 => array:2 [ "identificador" => "abst0015" "titulo" => "Results" ] 3 => array:2 [ "identificador" => "abst0020" "titulo" => "Conclusions" ] ] ] 1 => array:2 [ "identificador" => "xpalclavsec1418421" "titulo" => "Keywords" ] 2 => array:3 [ "identificador" => "xres1574106" "titulo" => "Resumen" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "abst0025" "titulo" => "Antecedentes y objetivo" ] 1 => array:2 [ "identificador" => "abst0030" "titulo" => "Materiales y métodos" ] 2 => array:2 [ "identificador" => "abst0035" "titulo" => "Resultados" ] 3 => array:2 [ "identificador" => "abst0040" "titulo" => "Conclusiones" ] ] ] 3 => array:2 [ "identificador" => "xpalclavsec1418422" "titulo" => "Palabras clave" ] 4 => array:2 [ "identificador" => "sec0005" "titulo" => "Introduction" ] 5 => array:3 [ "identificador" => "sec0010" "titulo" => "Material and method" "secciones" => array:1 [ 0 => array:2 [ "identificador" => "sec0015" "titulo" => "Statistic analysis" ] ] ] 6 => array:3 [ "identificador" => "sec0020" "titulo" => "Results" "secciones" => array:3 [ 0 => array:2 [ "identificador" => "sec0025" "titulo" => "Discrimination ability of Gd-IgA1 and APRIL" ] 1 => array:2 [ "identificador" => "sec0030" "titulo" => "Relationship between Gd-IgA1 and APRIL with the rest of the variables" ] 2 => array:2 [ "identificador" => "sec0035" "titulo" => "Relationship between Gd-IgA1 and the evolution of IgAN" ] ] ] 7 => array:3 [ "identificador" => "sec0040" "titulo" => "Discussion" "secciones" => array:5 [ 0 => array:2 [ "identificador" => "sec0045" "titulo" => "Ability of Gd-IgA1 to discriminate between patients with and without IgAN" ] 1 => array:2 [ "identificador" => "sec0050" "titulo" => "Relationship between circulating Gd-IgA1 and histological findings" ] 2 => array:2 [ "identificador" => "sec0055" "titulo" => "Relationship between circulating Gd-IgA1 and clinical and analytical variables" ] 3 => array:2 [ "identificador" => "sec0060" "titulo" => "Relationship between circulating Gd-IgA1 and CKD progression" ] 4 => array:2 [ "identificador" => "sec0065" "titulo" => "Role of APRIL in the diagnosis of IgAN" ] ] ] 8 => array:2 [ "identificador" => "sec0070" "titulo" => "Conflict of interests" ] 9 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2020-07-22" "fechaAceptado" => "2020-12-07" "PalabrasClave" => array:2 [ "en" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Keywords" "identificador" => "xpalclavsec1418421" "palabras" => array:9 [ 0 => "IgA Nephritis" 1 => "Galactose-deficient IgA1" 2 => "KM55" 3 => "Lectin-independent ELISA" 4 => "MEST-C" 5 => "IgAN Prognostic tools" 6 => "APRIL" 7 => "IgANPC" 8 => "IRPT-IgAN" ] ] ] "es" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Palabras clave" "identificador" => "xpalclavsec1418422" "palabras" => array:10 [ 0 => "IgA Nephritis" 1 => "Galactose-deficient IgA1" 2 => "Gd-IgA" 3 => "KM55" 4 => "Lectin-independent ELISA" 5 => "MEST-C" 6 => "IgAN Prognostic tools" 7 => "APRIL" 8 => "IgANPC" 9 => "IRPT-IgAN" ] ] ] ] "tieneResumen" => true "resumen" => array:2 [ "en" => array:3 [ "titulo" => "Abstract" "resumen" => "<span id="abst0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0010">Background and objective</span><p id="spar0040" class="elsevierStyleSimplePara elsevierViewall">About 25% of patients with IgA nephropathy (IgAN) progress to stage 5 chronic kidney disease (CKD) after years of evolution.
