We studied 72 patients (65 women, 7\u00a0men) with primary hyperparathyroidism (pHPT). Clinical presentation, biochemical indices,\nand bone mineral density (BMD) were compared in three patient groups classified according to their serum 25\u2010hydroxyvitamin D (25OHD)\nlevels: 23 patients whose 25OHD level was &lt;25\u00a0nmol\/L comprised the low group, 26 whose level was 25 to 40\u00a0nmol\/L made up the intermediate group, and 23 whose level was &gt; 40\u00a0nmol\/L comprised the high group. The mean serum calcium level was 10.8 \u00b1 0.9\nmg\/dl, and the mean weight of the resected parathyroids was 684 \u00b1\n749\u00a0mg. The mean serum 25OHD level was 36.5 \u00b1 16.3\u00a0nmol\/L (normal\n25\u2013100\u00a0nmol\/L). Levels were below normal in 23 patients (32%). No between\u2010group differences existed for clinical presentation,\nbiochemistry, or BMD. Only differences in mean patient age were statistically significant between groups. Vitamin D deficiency is common among Japanese patients with pHPT, but the effects of HPT on clinical, biochemical, and densitometric indices are not pronounced.\nOur study population was at an early stage of pHPT, so the vitamin D deficiency may not be associated with the effects of HPT.\n<\/jats:p>","DOI":"10.1007\/s00268-002-6622-z","type":"journal-article","created":{"date-parts":[[2002,10,14]],"date-time":"2002-10-14T16:45:16Z","timestamp":1034613916000},"page":"937-941","source":"Crossref","is-referenced-by-count":32,"title":["Vitamin
