Multicenter Research Study to Build a Repository to Study Chronic Diseases in Indiana

Study Aim: The purpose of this study is to create an extensively annotated bio-repository platform for hypothesis-driven research that will lead to advancements in the diagnosis, treatment and prevention of diseases common to the population of Indiana. The second phase of this research platform will be created by collecting blood samples from two groups of individuals in the Central Indiana community, one with documented evidence of Diabetes Mellitus Type II(T2D), and a second group of age, gender and ethnicity matched individuals without clinical evidence of Diabetes. Each individual's blood sample will be linked to their clinical, demographic and epidemiological information, gathered both retrospectively and prospectively. Recruitment: This study will include 500 individuals with T2D (the T2D Group) and 500 individuals who are age, gender, and ethnicity matched to the T2D Group, but without presentation of clinical evidence of T2D (the Control Group). To reflect the growing representation of Hispanics in Central Indiana, Hispanics will be overly recruited in both groups so that the study population accurately reflects the general population of Central Indiana. Follow-up: As this is a prospective, longitudinal study, follow-up of study subjects is intended to include two follow up visit and continue indefinitely, unless, of course, at any time, consent for further follow-up is withdrawn by the subject. Follow-up will include visits at 2 and 5 years post initial contact and continuing access to the subject's medical record to pursue data concerning changes in the subject's health. Subjects may be contacted by telephone, mail or email every twelve months to ask if they wish to continue participation in the study. The 2 and 5 year follow up visits mirror the initial visit. The collected dataset (made up of the collected blood samples linked to clinical and epidemiological information collected retrospectively and prospectively), will be used in medical research to find genes, or gene products such as RNA or proteins that will help in understanding the causes of disease and will guide the development of new treatments
