Thirty of these patients had mild pHPT and are reported separately.

Bone density was measured at the distal radius by single photon absorptiometry (SPA).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>.Bone formation markers consistenly decreased after parathyroid surgery: ALP from 3.51 \u00b1 0.23 to 2.94 \u00b1 0.21 \u00b5kat L<jats:sup>\u22121<\/jats:sup> (<jats:italic>P<\/jats:italic> &amp;lt; 0.05), osteocalcin from 6.15 \u00b1 0.53 to 2.89 \u00b1 0.23 \u00b5g L<jats:sup>\u22121<\/jats:sup> (<jats:italic>P<\/jats:italic> &amp;lt; 0.001) and PICP from 126.4 \u00b1 10.9 to 96.0 \u00b1 6.5 \u00b5g L<jats:sup>\u22121<\/jats:sup> (<jats:italic>P<\/jats:italic> &amp;lt; 0.001). In parallel, the ICTP concentration, reflecting bone resorption, decreased from 5.10 \u00b1 0.54 to 3.94 \u00b1 0.34 \u00b5g L<jats:sup>\u22121<\/jats:sup> (<jats:italic>P<\/jats:italic> &amp;lt; 0.001). There was not any significant change in distal radius bone mineral 1 one year after surgery. In the subgroup of patients classified as mild pHPT, a significant decrease was noted for osteocalcin, PICP and for ICTP but not for ALP, without significant changes in variables reflecting distal radius bone mineral content. Glomerular filtration rate was inversely correlated to serum levels of intact PTH, ionized calcium, alkaline phosphatase, osteocalcin and ICTP and directly correlated to the 1.25\u2010dihydroxy\u2010vitamin D concentrations.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>.pHPT is associated with substantial changes in circulating levels of biochemical markers of bone formation and resorption. These findings are also present in patients with mild pHPT. Renal function should be considered in the evaluation of the impact of pHPT on bone turnover.<\/jats:p><\/jats:sec>","DOI":"10.1046\/j.1365-2796.1998.00241.x","type":"journal-article","created":{"date-parts":[[2003,3,12]],"date-time":"2003-03-12T06:06:44Z","timestamp":1047449204000},"page":"115-122","source":"Crossref","is-referenced-by-count":39,"title":["Increased biochemical markers of bone formation and resorption in primary hyperparathyroidism with special reference to patients with mild disease"],"prefix":"10.1111","volume":"243","author":[{"family":"Valdemarsson","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Linderg\u00e5rd","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Tibblin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Bergenfelz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2008,10,9]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-114-7-593"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0169-6009(08)80100-6"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/8756-3282(93)90207-Q"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-121-10-199411150-00003"},{"key":"e_1_2_5_6_2","first-page":"112","article-title":"Total and regional bone mineral content in primary hyperparathyroidism: sex differences.","volume":"20","author":"Rico H","year":"1994","journal-title":"Miner Electrolyte Metab"},{"key":"e_1_2_5_7_2","doi-asserted-by":"publisher","DOI":"10.1210\/jc.80.3.729"},{"key":"e_1_2_5_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2265.1995.tb02668.x"},{"key":"e_1_2_5_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0169-6009(08)80020-7"},{"key":"e_1_2_5_10_2","doi-asserted-by":"publisher","DOI":"10.1210\/jc.80.3.723"},{"key":"e_1_2_5_11_2","first-page":"955","article-title":"Plasma clearance of a new contrast agent, iohexol: A method for the assessment of glomerular filtration rate.","volume":"104","author":"Krutz\u00e9n E","year":"1984","journal-title":"J Lab Clin Med"},{"key":"e_1_2_5_12_2","doi-asserted-by":"publisher","DOI":"10.3109\/00365518909091539"},{"key":"e_1_2_5_13_2","first-page":"1","article-title":"Bone mineral content measured by photon absorptiometry \u2014 a methodological study carried out in normal individuals.","volume":"59","author":"Linderg\u00e5rd B","year":"1981","journal-title":"Scand J Urol Nephrol"},{"key":"e_1_2_5_14_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00298553"},{"key":"e_1_2_5_15_2","doi-asserted-by":"publisher","DOI":"10.1530\/eje.0.1300587"},{"key":"e_1_2_5_16_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00311432"},{"key":"e_1_2_5_17_2","doi-asserted-by":"publisher","DOI":"10.1002\/jbmr.5650080202"},{"key":"e_1_2_5_18_2","first-page":"689","article-title":"Cortical bone mineral content in primary hyperparathyroidism.
