Principal Investigator: Gary Curhan, MD, ScD, FASN Professor of Medicine, Harvard Medical School, Channing Laboratory/Renal Division Brigham and Women's Hospital , Boston, MA USA MeSH: Nephrolithiasis,Urolithiasis,Kidney Calculi,Hypercalciuria,Hyperoxaluria https://www.ncbi.nlm.nih.gov/projects/gap/cgi-bin/study.cgi?study_id=phs000460 Genetic and environmental factors play an important role in the etiology of nephrolithiasis. This project will build on and extend our previous efforts (examining environmental risk factors for stone formation) by allowing us to study the risk of stone formation associated with specific genes and gene-environment interactions. We will take advantage of previously collected data in three large cohort studies: Nurses' Health Study I (n=121,000 women), Nurses' Health Study II (n=116,000 women), and Health Professionals Follow-up Study (n=51,000 men). Over a period of 17 to 26 years, information has been collected prospectively on important exposures including diet, family history, body size measures, past medical history, and medications. We have confirmed over 2000 incident cases of kidney stones in each cohort (DK59583, PI Curhan). Further, we have collected 24-hour urine samples from over 4100 stone formers and non-stone formers; the majority of participants have performed two collections. The primary objective of this project is to examine the association between single nucleotide polymorphisms and the 24-hour urinary excretion of stone promoters (calcium and oxalate) and a stone inhibitor (citrate). The secondary objective is to explore the impact of interactions between the genetic factors and dietary factors on 24-hour urinary excretion of relevant lithogenic factors. These findings should provide new insight into regulation of these important factors and also into novel approaches for prevention of stone formation.

Twenty-four-hour urine samples were collected in two cycles as part of a study to compare the urine composition of stone formers to non-formers. In the first cycle, which spanned from 1994 to 1999, we obtained one 24-hour urine collection from 1046 participants. The second cycle began in 2003 when we invited additional stone formers and randomly selected controls to perform two 24-hour urine collections. In the first cycle, participants were ineligible if they were >70 years of age in HPFS or >65 years in NHS I or had a history of cancer or cardiovascular disease. In the second cycle, participants were ineligible if they were older than 75 years of age or had a history of cancer (other than non-melanoma skin cancer).

The rates of participation and completion among stone-forming and non-stone-forming participants in each cohort were reported previously. The 24-hour urine collection procedure used the system provided by Mission Pharmacal (San Antonio, TX). The demographic characteristics and dietary intake of participants who collected urine and those who did not were similar.
