[Renal osteodystrophy in Spain. Multicenter survey. (I). Collaborative Centers of the Multicenter Study on Renal Osteodystrophy].
In order to know the current management of renal osteodystrophy in Spain we collected data from 172 centres (10,724 patients) obtained from a 30 questions enquiry designed to show different aspects of the current management of renal osteodystrophy. The levels considered the "goal" for treatment were: Calcium 10-10.5 mg/dL (53% of centres), 9.5-10 mg/dL (28%), 10.5-11 mg/dL (14%) and 9-9.5 mg/dL (5% of centres). Phosphorus: between 4.5 and 5.5 mg/dL (77% of centres), between 5.5 and 6.5 mg/dL (15%) and less than 4.5 mg/dL (8% of centres). Parathormone (PTH): between 120 and 250 pg/mL (75% of centres), between 60 and 120 pg/mL (19% of centres). The calcium concentration used in the dialysis fluids was 2.5 in 44% of centres, 3 in 28%, 3.5 in 26% and 2 mEq/L in the remaining 2% of centres. Pulse therapy was started with PTH higher than 750 in 16% of centres; with PTH higher than 500 pg/mL in 52% and with PTH higher than 250 pg/mL in 28% of the centres. Only 51% of centres decreased the calcium concentration in dialysis fluids when the patients were receiving parenteral calcitriol. Fifty-nine percent of centres considered a positive response to treatment any reduction in PTH levels, 24% of centres considered response a decrease of at least 20%, 78% of centres maintained the treatment with calcitriol 6 months before deciding if the patient was a "responder" or a "non-responder". Parathyroidectomy was performed when PTH was higher than 1,000 pg/mL in 38% of the centres; in 41% when PTH was between 1,000 and 750; in 19% when PTH was between 750 and 500; and when PTH was between 500 and 250 pg/mL in the remaining 2% of the centres. Five percent of the patients had a parathyroidectomy.
