title: Bone turnover in short-term and long-term home parenteral nutrition for benign disease.
abstract: 6 mo afterward. Long-HPN was assessed only at baseline. In short-HPN, there was a hyperkinetic turnover at baseline. At follow-up, OC was similar to baseline, whereas cross-links, urinary calcium and magnesium decreased (P < 0.03), and parathyroid hormone increased (P < 0.001). The variation of urinary calcium correlated with that of cross-links (r = 0.73, P < 0.04). In long-HPN, OC was low or low-normal in almost all the patients, and cross-links were normal. Mean OC was lower than that of short-HPN both at baseline (P < 0. 003) and at follow-up (P < 0.002). The results suggest that in the early period of HPN bone metabolism improved from a hyperkinetic turnover to a positive balance. A low bone-formation rate appeared to be a characteristic feature of long-term HPN.
