Biochemical parameters in patients on dialysis with normal to high bone turnover, pure osteomalacia, and adynamic bone disease
| Parameter | Dialysis: Normal to High Bone Turnover (n=52) | Dialysis: Pure Osteomalacia (n=7) | Dialysis: Adynamic Bone (n=9) |
|---|---|---|---|
| Calcium, mg/dl | 9.4±0.1 | 7.7±1.1 | 8.9±1.1 |
| Phosphorus, mg/dl | 6.0±0.1 | 7.0±1.0 | 6.2±0.7 |
| Alkaline phosphatase, IU/L | 337±38 | 127±23a | 538±145b |
| PTH (first generation IMA) | 736 (422, 1063) | 293 (289, 555) | 45 (21, 220)c |
Values are expressed as mean+SD, except PTH, which is expressed as median (interquartile range). PTH, parathyroid hormone; IMA, immunometric assay.
a
P<0.001 between osteomalacia and normal to high bone turnover.
b
P=0.04 between adynamic bone and osteomalacia.
c
P<0.001 between adynamic bone and normal to high bone turnover.
