title: Renal osteodystrophy in CAPD patients.
abstract: To assess the influence of continuous ambulatory peritoneal dialysis (CAPD) on the evolution of renal osteodystrophy, we studied 36 adult patients with end-stage renal failure before starting dialysis and after 7-30 months. 17 patients (12 males and 5 females) were treated by CAPD as first treatment and 19 (14 males and 5 females) received maintenance hemodialysis. The two groups were age- and sex-matched and no patient received vitamin D. All patients had adequate clinical and metabolic follow-up with a radiological survey and quantitative bone histology at the start of dialysis and at the end of the study. Serum phosphate concentrations were much easier to control in CAPD than in hemodialysis patients. There was no difference in the evolutive pattern of vascular and periarticular calcifications in the two groups. The 25-hydroxyvitamin D3 levels were frequently lower in CAPD than in hemodialysis patients. In some CAPD patients, there was a significant loss of trabecular bone volume at the end of the study. The radiological and histological appearances of secondary hyperparathyroidism improved or seemed to worsen to a lesser degree in CAPD compared to hemodialysis patients.
