NCT02673762

Brief Summary

A PRoBE design study will be used to obtain saliva from patients before undergoing blood study evaluation for screening at risk patients for the presence of undiagnosed pre-diabetes of type II diabetes. Pre-specified saliva biomarkers will be evaluated along with multi-marker models for their discriminatory value for distinguishing patients with normal glucose metabolism from those with disease. Appropriate housekeeping genes will also be incorporated to allow for the measurement of relative gene expression.

Outcome Measures

Primary Outcomes (1)

  • A multi marker test score based on a pre-specified model is measured in each patient. The test score is on a scale of 0 to 1.0 and relates to the probability of disease.

    The area under the ROC curve is used to determine the overall performance of the model at the completion of the study. An area over 0.7 is considered clincially significant.

    At study entry

Secondary Outcomes (2)

  • Pre-specified mRNA marker Ct values from PCR analysis will be measured in individual patients

    At study entry

  • Housekeeping gene Ct values on PCR analysis will be measured in individual patients

    At study entry

Study Arms (3)

Normal glucose metabolism

Normal fasting blood glucose, 2 hour post prandial glucose, hemoglobin A1c and HOMA IR

Pre-diabetes

Abnormal glucose tolerance tests and/or insulin resistance with fating blood glucose and hemoglobin A1c below type II diabetes levels

Type II diabetes

Hemoglobin A1c 6.5% or greater, fasting blood glucose \>125 mg/dl or 2 hour post-prandial blood glucose 200 mg/ml or greater
