Introduction:

mineral and bone disorder (BMD) is a serious complication of chronic kidney disease (CKD) that increases risks for death from cardiovascular causes and impairs quality of life of affected patients.

Objective:

to evaluate the prevalence of BMD in patients with CKD and the association between estimated Glomerular Filtration Rate (eGFR) and BMD indicators (calcium, phosphorus and PTH) in non-dialysis patients.

Materials and Methods:

sectional study of a two-year cohort of chronic renal adults and elderly patients on conservative treatment. BMD was identified by serum values of: PTH (> 150 pg/mL) and/or hypocalcemia (Ca < 8.8mg/dl) and/or hyperphosphatemia (P > 4.6 mg/dl). The statistical analysis used: Poisson regression; Student's T, Mann Whitney and Pearson and Spearman correlations with 5% significance level.

Results:

BMD prevalence was 54.6% (n=41) (95% CI: 43.45 - 65.43), more frequent in women, literate, elderly, non-drinkers, non-smokers, sedentary and white skin color. Correlations between P and PTH with GFRe were significant, inverse, moderate strength (p= <0.005 and p = 0.003; correlation coefficients = - 0.312 and - 0.379 respectively). the findings of this study highlighted gaps in the monitoring of BMD-DRC by primary care, requiring a review of clinical practices.

Conclusion:

robust prevalence of BMD in the early stages of CKD was identified, in addition to correlations between increased phosphorus and PTH levels and worsening kidney function.
