Chronic Kidney Disease in Children

Alternate Titles(s): CKiD
UID: 10799
Description

The Chronic Kidney Disease in Children (CKiD) Study is a multicenter, observational, prospective cohort study of children, adolescents, and young adults with a history of mild to moderately impaired kidney function. The primary goals of the study are to determine the risk factors for decline in kidney function, how a progressive decline in kidney function impacts neurocognitive function and behavior, risk factors for cardiovascular disease, and associations between growth failure and morbidity. CKiD began in 2003 and has enrolled four cohorts, totaling over 1000 participants across the United States and Canada.

At baseline, participants underwent a physical examination, and data were collected on kidney, cardiovascular, and neurocognitive symptoms and function, as well as information on demographics, medications, genetics, and growth. Biospecimens, including serum, plasma, and urine, are also collected. Similar measures are assessed at annual follow-ups. The primary outcome measure is the rate of decline of glomerlular filtration rate (GFR). Participants are followed through their initiation of dialysis or transplant in order to more fully understand the course of the disease and the population’s health beyond kidney replacement therapy (KRT). Data are also collected on important clinical events, such as the onset of end-stage kidney disease, that are particularly meaningful to the population.
