Association between Extreme Values of Markers of Chronic Kidney Disease: Mineral and Bone Disorder and 5-Year Mortality among Prevalent Hemodialysis Patients.
2018
BACKGROUND/AIMS:We examined the association between markers of chronic kidney disease - mineral and bone disorder (CKD-MBD) and mortality in hemodialysis (HD) patients. METHODS:We retrospectively reviewed the association between markers of CKD-MBD and mortality in 1,126 HD patients from 2009 to 2013 with baseline (B), time-average (TA), and time-dependent (TD) Cox regression models. RESULTS:Hypercalcemia (10.9-11.9 mg/dL) indicated an increased risk of all-cause mortality (TA: hazard ratio [HR] 3.49; p = 0.01). Hypophosphatemia (2.0-2.5 mg/dL) was significantly associated with an increased risk of all-cause mortality (TA: HR 5.18; p = 0.01). Hypophosphatemia ( 1,500 pg/mL indicated an increased risk of all-cause mortality (TA: HR 1.64; p = 0.02; TD: HR 2.26; p = 0.02). CONCLUSION:Extreme values of CKD-MBD markers are associated with mortality risk in HD patients. Video Journal Club 'Cappuccino with Claudio Ronco' at http://www.karger.com/?doi=478972.
