Renal bone disease is an important cause of morbidity in patients on dialysis. The prevalence of renal bone disease, especially aluminium related bone disease, has not been studied in the Singapore dialysis population. As such, we studied 45 haemodialysis patients for renal bone disease using biochemical and radiological parameters. Selected patients underwent a renal biopsy. There were 29 males and 16 females, mean (+/- SEM) age, 44.6 +/- 13.4 years. The duration of haemodialysis ranged from two months to ten years, mean 18.5 months. 75.4% of patients had hyperphosphatasemia, 24.4% had hypocalcemia and two patients had hypercalcemia. There was a wide range in the serum parathyroid hormone levels and 55.4% of patients had serum parathyroid hormone levels > 1000 pmol/L. Patients with symptoms and radiological abnormalities had significantly higher serum parathyroid hormone and alkaline phosphatase levels than those without (P < 0.005). The desferrioxamine infusion test was positive, with an increment in serum aluminium (DL) > 100 mg/L in five patients. Skeletal survey was positive for renal bone disease in 24.4% of patients. There was a significant correlation between the serum parathyroid hormone level, DA1 and the duration of dialysis (r = 0.752, p < 0.001 and r = 0.837, p < 0.001 respectively). There was no correlation between serum parathyroid hormone, calcium, phosphate levels and DA1. The serum haemoglobin concentration and ferritin levels did not show a correlation with DA1. Bone biopsy revealed hyperparathyroid bone disease in two patients, aluminium-related bone disease in one patient and mixed uraemic osteodystrophy in one patient.(ABSTRACT TRUNCATED AT 250 WORDS)
