Does stage III chronic kidney disease always progress to end-stage renal disease? A ten-year follow-up study.
Clinically, it may be appropriate to subdivide patients with stage 3 chronic kidney disease (CKD) into two subgroups, as they show different risks for kidney outcomes. This study evaluated the proportion of patients with stage 3 CKD who progressed to stage 4 or 5 CKD over 10 years and independent predictors of progression of renal dysfunction. It sought to validate whether stage 3 CKD patients should be subdivided. ⋯ About half of the patients with stage 3 CKD progressed to stage 4 or 5, as assessed by eGFR, over 10 years. Degree of albuminuria, stage 3 subgroup and microscopic haematuria were important risk factors for progression of stage 3 CKD. It would be appropriate to divide the present stage 3 CKD into two subgroups.
