|This is a drawing of a glomerulus, done by Dr. Charles Jennette. There are millions of glomeruli in your kidney. Glomeruli are tiny, ball-shaped structures made of blood vessels. Glomeruli help filter blood and turn it into urine.|
The Glomerular Disease Collaborative Network (GDCN)
was established in 1985 as a means of enhancing communication
and research efforts between community nephrology offices
and the University of North Carolina at Chapel Hill
School of Medicine. The purpose of the GDCN is to learn
more about causes and pathogenesis of glomerular diseases,
as well as to find the most effective treatments for
patients with these diseases.
The co-founders and co-directors of the GDCN are Ronald J. Falk, MD, Allen Brewster Distinguished Professor of Medicine and Chief of the Division of Nephrology and Hypertension, and J. Charles Jennette, MD, Brinkhous Distinguished Professor and Chair, Department of Pathology & Laboratory Medicine, and Professor of Medicine, Department of Medicine, both of the University of North Carolina at Chapel Hill.
The foundation of the GDCN is the ongoing enrollment and follow-up of patients in sixteen specific glomerular disease registries.
The goal of the patient registries is to identify patients at the onset of their disease and to follow the course of their disease throughout their life. Continual updates of patient's medical records and contact information for the registries allow the GDCN to recruit patients for participation in a variety of more focused studies that may include collection of blood or urine, completion of questionnaires or telephone interviews and participation in treatment studies. In the case of treatment studies, patients are not contacted directly but if they are potentially eligible, their physician is contacted with the specifics of the study. The GDCN is continually enrolling patients in all registries, but currently the studies that are most actively recruiting include diagnoses of focal segmental glomerulosclerosis, membranous glomerulopathy, lupus nephritis and ANCA-associated vasculitis.
Patients are usually identified for the GDCN registries by having their renal biopsy tissue evaluated at the UNC Nephropathology Laboratory, a diagnostic laboratory that provides this specialty service to many private practice nephrology offices throughout the United States. Patients are sent information about the registries through their own nephrologists, and informed patient or parental consent is required for their enrollment into the registry for long term follow-up of their medical records. Additional consent is needed for studies that require collection of samples, completion of questionnaires or interviews or for treatment trials.
Patients who are not identified as described above can still participate in the registries, and are identified either by their own nephrologists or through collaborative research efforts with other nephropathology laboratories. Recruitment through these mechanisms is most often done to increase recruitment of patients for specific studies or among age groups or diseases where inclusion of as many patients as possible is needed to attain the numbers needed to answer specific research questions.
