We studied in a CKD patient cohort with two years follow-up, whether validated 24-h urine ionogram would be a relevant tool for diet evaluation and compliance. We included 404 non-dialysis CKD patients, with three evaluations, including repeated measurements of fractional renal creatinine clearance and 24-h urine collection. Completeness of the 24-h urine collection, assessed by daily urine creatinine excretion extrapolated from fractional creatinine clearance, was 64.6%, 75.5%, and 78.2% at the first, second, and third visits, respectively. One hundred sixty-eight patients (41.6%) had three complete collections, with a measured glomerular filtration of 42.3 mL\/min\/1.73 m2 at baseline and prevalence of anemia and secondary hyperparathyroidism of 13.9% and 26.2%, respectively, increasing during follow-up to 15% and 31.5% (p &lt; 0.001 and p &lt; 0.001). The urine analysis showed at baseline a urine volume of above 2 L\/day, and estimated sodium and protein intake within targets in 51.6% and 40.3% of cases, which improved during follow-up only for protein (to 45.9%, p &lt; 0.0001). Our data suggest that a 24-h urine ionogram is an interesting, reliable tool in CKD patients for dietary monitoring to achieve target recommendation noteworthy salt and protein intake.<\/jats:p>","DOI":"10.3390\/nu12092615","type":"journal-article","created":{"date-parts":[[2020,8,27]],"date-time":"2020-08-27T08:05:18Z","timestamp":1598515518000},"page":"2615","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["24-h Urine Collection: A Relevant Tool in CKD Nutrition Evaluation"],"prefix":"10.3390","volume":"12","author":[{"given":"Moustafa","family":"Abdel-Nabey","sequence":"first","affiliation":[{"name":"Service d\u2019Explorations Fonctionnelles Multidisciplinaires, AP-HP, H\u00f4pital Tenon, Sorbonne Universit\u00e9, 75020 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Camille","family":"Saint-Jacques","sequence":"additional","affiliation":[{"name":"Service d\u2019Explorations Fonctionnelles Multidisciplinaires, AP-HP, H\u00f4pital Tenon, Sorbonne Universit\u00e9, 75020 Paris, France"},{"name":"INSERM, UMR_S 1155, AP-HP, H\u00f4pital Tenon, Sorbonne Universit\u00e9, 75020 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Jacques","family":"Boffa","sequence":"additional","affiliation":[{"name":"INSERM, UMR_S 1155, AP-HP, H\u00f4pital Tenon, Sorbonne Universit\u00e9, 75020 Paris, France"},{"name":"Service de N\u00e9phrologie, AP-HP, H\u00f4pital Tenon, Sorbonne Universit\u00e9, 75020 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vincent","family":"Frochot","sequence":"additional","affiliation":[{"name":"Service d\u2019Explorations Fonctionnelles Multidisciplinaires, AP-HP, H\u00f4pital Tenon, Sorbonne Universit\u00e9, 75020 Paris, France"},{"name":"INSERM, UMR_S 1155, AP-HP, H\u00f4pital Tenon, Sorbonne Universit\u00e9, 75020 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marine","family":"Livrozet","sequence":"additional","affiliation":[{"name":"Service d\u2019Explorations Fonctionnelles Multidisciplinaires, AP-HP, H\u00f4pital Tenon, Sorbonne Universit\u00e9, 75020 Paris, France"},{"name":"INSERM, UMR_S 1155, AP-HP, H\u00f4pital Tenon, Sorbonne Universit\u00e9, 75020 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michel","family":"Daudon","sequence":"additional","affiliation":[{"name":"Service d\u2019Explorations Fonctionnelles Multidisciplinaires, AP-HP, H\u00f4pital Tenon, Sorbonne Universit\u00e9, 75020 Paris, France"},{"name":"INSERM, UMR_S 1155, AP-HP, H\u00f4pital Tenon, Sorbonne Universit\u00e9, 75020 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Flamant","sequence":"additional","affiliation":[{"name":"Department of Physiology, University Paris Descartes-Paris 5, AP-HP, H\u00f4pital Bichat, 75018 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emmanuel","family":"Letavernier","sequence":"additional","affiliation":[{"name":"Service d\u2019Explorations Fonctionnelles Multidisciplinaires, AP-HP, H\u00f4pital Tenon, Sorbonne Universit\u00e9, 75020 Paris, France"},{"name":"INSERM, UMR_S 1155, AP-HP, H\u00f4pital Tenon, Sorbonne Universit\u00e9, 75020 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2756-2287","authenticated-orcid":false,"given":"Jean-Philippe","family":"Haymann","sequence":"additional","affiliation":[{"name":"Service d\u2019Explorations Fonctionnelles Multidisciplinaires, AP-HP, H\u00f4pital Tenon, Sorbonne Universit\u00e9, 75020 Paris, France"},{"name":"INSERM, UMR_S 1155, AP-HP, H\u00f4pital Tenon, Sorbonne Universit\u00e9, 75020 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"260","DOI":"10.1016\/S0140-6736(13)60687-X","article-title":"Chronic kidney disease: Global dimension and perspectives","volume":"382","author":"Jha","year":"2013","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2173","DOI":"10.1016\/S0140-6736(08)60952-6","article-title":"All-cause mortality attributable to chronic kidney disease: A prospective cohort study based on 462 293 adults in Taiwan","volume":"371","author":"Wen","year":"2008","journal-title":"Lancet"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"1344","DOI":"10.1056\/NEJMe048211","article-title":"Chronic Kidney Disease Predicts Cardiovascular Disease","volume":"351","author":"Hostetter","year":"2004","journal-title":"N.
