Control of mineral metabolism and bone disease in haemodialysis patients: which optimal targets?

The findings of our observational study confirm the existence of a grey zone, in which precise biochemical targets are difficult to define, with the exception of avoiding extreme values. Given the absence of intervention trials proving the clinical usefulness of phosphorus control, and pending the results of large clinical trials on the effect of optimal PTH and calcium control on hard outcomes, the present findings may help to refine future recommendations for the treatment of chronic haemodialysis patients.
