2017 Update2009 KDIGO Controversies Conference 2013 “CKD-MBD: Back to the Future
A total of 12 recommendations were
identified for revision.
•Work Group acknowledged the lack of high-quality evidence on which to base recommendations.
•Multiple randomized controlled trials (RCTs) and prospective cohort studies.
•KDIGO recognizesthe need to reexamine the
currency of its guidelines.
▪2017 Update3 followed a rigorousprocess of evidence review and appraisal, based on systematicreviews of results from clinical trials.
▪GRADE
Where appropriate, the Work Group issued “not graded”recommendations, based on general advice, thatwere not part of a systematic evidence
review.

Secondary hyperparathyroidism (sHPT)
Attempt to control the disturbedcalcium, phosphorus, and vitamin Dmetabolism. sHPT causes vascular
and soft-tissue calcification and leadsto disturbances of mineral metabolismCKD-related mineral and
bone disorder (CKD-MBD).
CKD-MBD abnormalities have also been implicated as risk factors for the very rare but devastating calcific and thrombotic arteriolopathycalciphylaxis and lead to reduced health-related quality of life
(HRQoL).

Abnormalities in Metabolic Parameters Are Consequences of SHPT: Management of PTH, Ca, and P
Tomasello S. Diabetes Spectrum. 2008;21:19-25
Treatment approaches to the management of SHPT include Ca x P, PTH, and vitamin D.
Use of vitamin D and phosphate binders alone provide no direct way to control PTH levels without the risk of raising Ca and P levels.

• Prospective studies evaluating BMD testing inadults with CKD represent a substantialadvance since the original guideline from 2009,making a reasonable case for BMD testing if theresults will impact future treatment.
• It is important to emphasize theinterdependency of serum calcium, phosphate,and PTH for clinical therapeutic decision-making.

▫ Phosphate-lowering therapies may only beindicated in the case of “progressive or persistenthyperphosphatemia”.
▫ New evidence suggests that excess exposure toexogenous calcium in adults may be harmful inall severities of CKD, regardless of other risk
markers.

Take home messages
▫ It is reasonable to limit dietary phosphate intake, whenconsidering all sources of dietary phosphate (including“hidden” sources).
▫ The PRIMO and OPERA studies failed to demonstrateimprovements in clinically relevant outcomes but diddemonstrate increased risk of hypercalcemia. Accordingly,routine use of calcitriol or its analogs in CKD G3a-G5 is nolonger recommended.
