Abstract
BACKGROUND/ PURPOSE: This study aims to examine the characteristics of Taiwanese children with chronic kidney disease (CKD) and delineate the factors that lead to disease progression in this population. METHODS: We reviewed the records of the Taiwan Pediatric Renal Collaborative Study, a multicenter database of Taiwanese children with CKD. Multivariate regression analysis was used to identify the main factors associated with disease progression. RESULTS: A total of 382 children aged 1-18 years were included in the study (median age was 10.6 years; interquartile range: 6.4-13.8). There were 197 males (51.6%) and 185 females. CKD Stage 1 was diagnosed in 159 children (41.6%), Stage 2 in 160 (41.9%), Stage 3 in 51 (13.4%), and Stage 4 in 12 (3.1%). Fifty-six children (14.7%) experienced CKD progression. A multivariate analysis for all patients indicated that the risk for disease progression was increased in children with CKD secondary to a structural abnormality, genetic disease, anemia, elevated diastolic blood pressure, or elevated blood urea nitrogen. Compared with children with Stage 1 CKD, those with Stage 2 and Stage 4 CKD had decreased risk for CKD progression in this short-term cohort follow-up. CONCLUSION: CKD etiology affects disease progression. Careful monitoring and treatment of anemia and elevated blood pressure in children with CKD may slow disease progression.
