Primary Outcome Measures:
  • The primary outcome was the patients' ability to avoid repeat ED visits or hospitalization in either of the discharge regimens. [ Time Frame: 2 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • The secondary outcomes included the number of subjects who reached a fasting or pre-meal BG goal of 80 to 130 mg/dl and assessment of the beta cell function at the beginning and end of the study as measured by C-peptide levels during OGTT testing. [ Time Frame: 2 months ] [ Designated as safety issue: No ]

Enrollment: 80

Primary Completion Date: April 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Glipizide arm
Glipizide XL is an insulin secretagogue and is an extended release tablet designed to provide a controlled rate of delivery. Glipizide XL was chosen because it is the most frequently used discharge oral medication in our ED. It has a quick onset of action within a few hours after oral ingestion, lasts for 24 hours and has a powerful glucose lowering effect. In addition, there are very few contraindications to Glipizide XL and there is published literature regarding their use in subjects with severe hyperglycemia
Drug: Glipizide
Glipizide XL 10 mg once daily 30 mins before breakfast
Other Name: Glucotrol XL
Active Comparator: Glipizide + Glargine
Insulin Glargine is a recombinant human basal insulin analog. It was chosen since it is a non-peaking insulin with cover for 24 hours. It can be injected subcutaneously only once a day and has a low incidence of hypoglycemia
Drug: Glipizide and Glargine
Glipizide XL 10 mg daily 30 minutes before breakfast Insulin Glargine 10 units subcutaneously at bedtime daily
Other Name: Insulin Lantus

Detailed Description:

This study is an open label randomized controlled trial in adult DM2 patients seen in ED services at John H. Stroger Hospital of Cook County serving a largely uninsured/underserved population. Individuals more than 18 years of age with DM2, either with new onset DM2 or known diabetics who did not take oral hypoglycemic agents for more than 2 weeks, presenting with fasting blood glucose (FBG) 300-500 mg/dl or random blood glucose (RBG) 400-700 mg/dl and who did not have any exclusion criteria listed in Table 1, were eligible for the study. Subjects were randomized to one of the two fixed dose treatment groups: 1) Glipizide XL 10 mg orally daily prior to breakfast (G group), 2) Glipizide XL 10 mg orally daily along with Insulin Glargine 10 units at bedtime, subcutaneously (G+G group).

  Eligibility

Ages Eligible for Study:   18 Years to 75 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:
