  Purpose

This study, done in collaboration with Johns Hopkins University School of Public Health in Baltimore, Maryland, will examine the role of genes in the development of atherosclerotic cardiovascular disease (CVD) in patients undergoing kidney dialysis. The rate of illness and death from CVD among patients on dialysis is extraordinarily high, accounting for about 50 percent of deaths. Blood levels of inflammatory markers are elevated in these patients, strongly predicting illness and death from CVD. The discovery of gene variants related to the inflammatory process in atherosclerotic CVD may lead to better medical treatments and improved survival in patients with end-stage kidney disease.

Participants of John's Hopkins University's CHOICE (Choices for Healthy Outcomes in Caring for End-Stage Renal Disease) program are included in this study. Blood samples previously collected from these patients will be analyzed in the laboratory for genes that might be associated with the inflammatory process and atherogenesis.

Detailed Description:

Background:

The CHOICE (Choices for Healthy Outcomes in Caring for End stage renal disease) study is a national prospective cohort study of 1,041 incident dialysis patients aged 19 to 95 recruited in 81 dialysis clinics between October 1995 and June 1998, and is overseen by the Johns Hopkins University School of Public Health.

The discovery of genetic associations offers the potential to direct clinical management in order to prevent ASCVD (Atherosclerotic Cardiovascular Disease) and improve survival in patients with end stage renal disease (ESRD).

Objectives:

In Collaboration with investigators of the CHOICE cohort, we propose to assess the role of variants in genes related to the inflammatory process on atherosclerotic cardiovascular disease (ASCVD) incidence.

Eligibility:

Eligibility is independent of age, race, ethnicity, and gender. However, no participants in this cohort are less than 19 years of age.

Design:

Frozen buffy coats from 871 patients will be sent to the LGD, and DNA will be extracted.

Singles nucleotide polymorphisms (SNPs) within coding regions, upstream or downstream regulatory regions or in intronic regions of candidates genes will be genotyped.

The first candidate genes under study include IL6, IL10, TGFB1, Beta Fibrinogen, LTA, and STAT3.

Blood samples and relevant clinical data will be provided by Johns Hopkins University School of Public Health, Department of Epidemiology with only numerical code which links samples and clinical data. While Johns Hopkins University will retain patient identifier information, the LGD will have no way of identifying the person from whom the blood, subsequent DNA, and clinical data are obtained.

The samples are maintained in our repository and curated through our central Laboratory database.

Destruction or loss of clinical samples or data will be recorded in our database and cannot impact the study participants in any way.

At the completion of this protocol, we will retain the samples for future use. We understand that studies subsequent to the completion of this protocol will require additional OHSR/IRB approval prior to commencement.
