BACKGROUND: Chronic kidney disease (CKD) is a global health burden, yet it is
still underrepresented within public health agendas in many countries. Studies
focusing on the natural history of CKD are challenging to design and conduct,
because of the long time-course of disease progression, a wide variation in
etiologies, and a large amount of clinical variability among individuals with
CKD. With the difference in health-related behaviors, healthcare delivery,
genetics, and environmental exposures, this variability is greater across
countries than within one locale and may not be captured effectively in a single
study. METHODS: Studies were invited to join the network. Prerequisites for
membership included: 1) observational designs with a priori hypotheses and
defined study objectives, patient-level information, prospective data acquisition
and collection of bio-samples, all focused on predialysis CKD patients; 2) target
sample sizes of 1,000 patients for adult cohorts and 300 for pediatric cohorts;
and 3) minimum follow-up of three years. Participating studies were surveyed
regarding design, data, and biosample resources. RESULTS: Twelve prospective
cohort studies and two registries covering 21 countries were included.
Participants age ranges from >2 to >70 years at inclusion, CKD severity ranges
from stage 2 to stage 5. Patient data and biosamples (not available in the
registry studies) are measured yearly or biennially. Many studies included
multiple ethnicities; cohort size ranges from 400 to more than 13,000
participants. Studies' areas of emphasis all include but are not limited to renal
outcomes, such as progression to ESRD and death. CONCLUSIONS: iNET-CKD
(International Network of CKD cohort studies) was established, to promote
collaborative research, foster exchange of expertise, and create opportunities
for research training. Participating studies have many commonalities that will
facilitate comparative research; however, we also observed substantial
differences. The diversity we observed across studies within this network will be
able to be leveraged to identify genetic, behavioral, and health services factors
associated with the course of CKD. With an emerging infrastructure to facilitate
interactions among the investigators of iNET-CKD and a broadly defined research
agenda, we are confident that there will be great opportunity for productive
collaborative investigations involving cohorts of individuals with CKD.
