Studies of renal osteodystrophy in patients maintained on CAPD for short
periods have shown conflicting results. The present study reports on the
status of renal osteodystrophy in 27 patients maintained on CAPD for over
three years. Ten men and 17 women with a mean age of 49.5 years were on CAPD
for a mean of 45 months. Dialysate calcium was 6 mg%. Oral dietary calcium
intake for all the patients was low (= 500 mg/day). AI(OH)3' Vit. D and/or
1,25(OH)2D3 were prescribed to maintain serum calcium and phosphorus at normal
levels. Patients were divided into two groups according to the radiological
findings at the beginning of treatment. Group A (10 patients) included those
who had no subperiosteal resorption (SPR) and Group B (17 patients) those with
SPR at the initiation of CAPD. In Group A, SPR grade remained normal in eight
patients and progressed in two. In Group B, SPR remained unchanged or
increased in 14 while it improved in the remaining three.
