However, such a link has not yet been reported in hypertensive patients with normal renal function. We aimed to evaluate if higher serum phosphate, calcium, parathyroid hormone (PTH) level and the calcium\u00d7phosphate (Ca\u00d7P) product would be associated with a nondipper hypertension, in patients with normal renal function and without any PTH disorder. &lt;i&gt;Methods:&lt;\/i&gt; 190 hypertensive subjects with the following inclusion criteria were enrolled: (1) normal phosphate and PTH levels; (2) glomerular filtration rate (GFR) &gt;60 ml\/min, and (3) no history of calcium, phosphate, vitamin D medication and hyperparathyroidism. &lt;i&gt;Results:&lt;\/i&gt; Of the total population, 76 patients (40%) were classified as dippers and 114 (60%) as nondippers. Nondipper patients had higher levels of phosphate (3.70 \u00b1 0.61 vs. 3.35 \u00b1 0.44 mg\/dl, p = 0.001), Ca\u00d7P product (35.4 \u00b1 6.5 vs. 31.5 \u00b1 5.0, p = 0.001) and PTH (75.7 \u00b1 28.8 vs. 46.6 \u00b1 17.1 pg\/ml, p = 0.000) compared to dipper patients. Independent predictors (multiple regression) for nondipper hypertension were PTH (\u03b2 = 0.43, p = 0.001) and phosphate (\u03b2 = 0.9, p = 0.03). &lt;i&gt;Conclusion:&lt;\/i&gt; We demonstrate a graded independent relation between higher levels of phosphate, PTH, Ca\u00d7P product and the risk of nondipping in hypertensive patients with an estimated GFR of &gt;60 ml\/min and normal mineral metabolism.<\/jats:p>","DOI":"10.1159\/000107489","type":"journal-article","created":{"date-parts":[[2007,8,17]],"date-time":"2007-08-17T09:30:02Z","timestamp":1187343002000},"page":"516-521","source":"Crossref","is-referenced-by-count":20,"title":["Relation between Serum Calcium, Phosphate, Parathyroid Hormone and \u2018Nondipper\u2019 Circadian Blood Pressure Variability Profile in Patients with Normal Renal Function"],"prefix":"10.1159","volume":"27","author":[{"given":"Mehmet","family":"Kanbay","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bunyamin","family":"Isik","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Akcay","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adem","family":"Ozkara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feridun","family":"Karakurt","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Faruk","family":"Turgut","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rabia","family":"Alkan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ebru","family":"Uz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nuket","family":"Bavbek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ramazan","family":"Yigitoglu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adrian","family":"Covic","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2007,8,16]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016%2FS0140-6736%2888%2992867-X"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1097%2F00004872-199512000-00003"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1097%2F00004872-199408000-00013"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1097%2F00004872-199508000-00002"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1038%2Fsj.jhh.1001907"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1161%2FCIRCULATIONAHA.105.553198"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1001%2Farchinte.166.8.846"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016%2FS0272-6386%2800%2970007-2"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1053%2Fajkd.1998.v31.pm9531176"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1161%2F01.HYP.0000202052.25238.68"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016%2FS0735-1097%2801%2901781-8"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1097%2F01.ASN.0000113243.24155.2F"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1681%2FASN.2004070602"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1523-1755.63.s85.26.x"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ehj.2003.09.010"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1093%2Fndt%2F12.5.933"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1152%2Fajpendo.00224.2004"}],"container-title":["American Journal of Nephrology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/107489","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/107489","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T02:49:12Z","timestamp":1745462952000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000107489"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007]]},"references-count":17,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2007,9,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000107489","archive":["Portico"],"relation":{},"ISSN":["0250-8095","1421-9670"],"issn-type":[{"value":"0250-8095","type":"print"},{"value":"1421-9670","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007]]}}}
