[Changes in mineral and bone disorder management in a French cohort of hemodialysis patients between 2008 and 2012: The National Bone and Mineral Metabolism observatory (Photo-Graphe 2 and 3)].

Abstract

INTRODUCTION:

Chronic kidney disease progressively induces a disorder of mineral and bone metabolism (CKD-MBD) which also leads to cardiovascular abnormalities. Previous studies showed that only few hemodialysis patients had serum calcium, phosphate and parathyroid hormone levels within the K/DOQI (Kidney-Disease Outcomes Quality Initiative) targets of 2003. Our aim was to identify the impact of different therapeutic strategies and that of the KDIGO (Kidney-Disease: Improving Global Outcomes) targets of 2009 on the control of CKD-MBD.

PATIENTS AND METHODS:

The French calcium and phosphate observatory monitors the mineral metabolism of patients with CKD at the local, regional and national level every six months. We compared the data recorded in June 2008 (n=1914 patients) with those collected in October 2012 (n=2481) for patients aged 18 years or more, who started hemodialysis therapy within the last 12 months.

RESULTS:

As compared with 2008, in 2012 fewer patients had hyperphosphatemia (55.1 % versus 64.7 %), hypocalcemia (35.5 % versus 40.3 %) and hyperparathyroidism (9.8 % versus 10.1 %) according to the KDIGO guideline, and more had hypophosphatemia (9.6 % versus 6.5 %), hypercalcemia (3.9 % versus 2.2 %) and hypoparathyroidism (31.5 % versus 25.8 %) (P<0.001, P<0.001 and P=0.002 respectively for differences in serum phosphate, calcium and PTH levels). Mean (± standard deviation [SD]) serum 25 OH vitamin D levels increased by 1.6-fold, from 48.3±42.6 nmol/L in 2008 to 76.6±45.8 nmol/L in 2012. Between 2008 and 2012, the prescription of native vitamin D derivatives and sevelamer (HCl or carbonate) increased whereas that of cinacalcet, lanthanum carbonate, calcium-chelating agents and active vitamin D derivatives decreased.

CONCLUSION:

Despite a slight improvement of biochemical CKD-MBD parameters in the observation period only few patients reached the three KDIGO targets (11.5 % in 2012 versus 11.1 % in 2008).
