    Abstract:
    Looser striae on the ischio-pubian branches and subperiosteal resorption of the phalanges were looked for in 113 chronic hemodialysis patients at the University Hospital of Annaba (Algeria) and were found in respectively 14 and 48 patients. Comparison of patients with and without radiological complications showed no significant difference in their age, sex ratio, nature of initial kidney disease and duration on dialysis. The patients with Looser striae had lower plasma levels of 25OHD3 than those without striae, whereas all other plasma parameters were similar. The plasma concentrations of intact PTH were higher in patients with resorption; these patients had lower plasma concentrations of calcium, bicarbonate, aluminum and 25OHD3 but similar plasma concentrations of phosphate and 1,25(OH)2D3. Multivariate analysis showed that PTH concentrations were independently linked only to plasma 25OHD3 (negatively) and duration on dialysis (positively). The results of this transversal study are in agreement with the well established pathophysiological roles of PTH hypersecretion, hypocalcemia and acidosis in the appearance of radiological hyperparathyroidism in hemodialysis patients. Furthermore they suggest that a relative native vitamin D deficiency may have a calcitriol independent role in favoring the occurrence of both osteitis fibrosa and osteomalacia.
