A1c Discordance in Diabetes Patients

This study has suspended participant recruitment.
(a pilot study of 7 patients did not reveal a temperature dependent difference in glycation rates)

  Purpose
HbA1c is used as a gold standard to see whether patients have optimal glycemic control. Today, many physicians rely solely on HbA1c to change medication. However, there is a select group of patients that have low average glucose levels but high HbA1c levels. The investigators believe that these patients are fast glycators meaning that they incorporate sugar into their hemoglobin faster than normal. The investigators want to determine whether these patients are fast glycators.

Condition Intervention
Diabetes Mellitus Other: Fast Glycator Other: Control

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Screening
Official Title: Differences in Hemoglobin Glycation Rate in Diabete Mellitus Patients

Further study details as provided by Endocrine Research Society:

Primary Outcome Measures:
  • Primary endpoint is to see whether they are fast glycators [ Time Frame: One Week ]

Secondary Outcome Measures:
  • A secondary endpoint includes adverse events such as unplanned hospitalizations for any cause that last more than 24 hours [ Time Frame: One Week ]

Estimated Enrollment: 25
Study Start Date: October 2010
Estimated Primary Completion Date: May 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Fast Glycator
The subjects enrolled in this study will have a fructosamine test and blood drawn to see whether they are fast glycators
Other: Fast Glycator
The subjects enrolled in this study will have a fructosamine test and blood drawn to see whether they are fast glycators
Active Comparator: Control
These patients will have their blood drawn to know what the normal glycation rate is in diabetic patients
Other: Control
These patients will have their blood drawn to know what the normal glycation rate is in diabetic patients
