Hypoglycemic unawareness is a major problem in the treatment of Diabetes Mellitus. Hypoglycemic unawareness is the inability to recognize or sense early symptoms of low blood sugar. This study was instituted to evaluate the effect of Pulsatile intravenous (IV) Insulin on improving or reinstating the diabetics ability to sense or feel the symptoms associated with low blood sugar.

Further study details as provided by Florida Atlantic University:

Primary Outcome Measures:
  • Questionnaires completed by subjects at baseline quarterly to assess ability to sense low blood sugar. Tracking incidences requiring outside assistance including paramedics, ER visits and hospitalizations due to low blood sugar incidences. [ Time Frame: Every 3 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 400
Study Start Date: January 2007
Estimated Study Completion Date: June 2012
Estimated Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Treatment
Diabetic patients will complete hypoglycemia unawareness questionnaires at baseline and quarterly thereafter to monitor and assess progress with complications resulting from their diabetes. Comparisons will be performed on low blood sugar incidences reported by subjects requiring heath care intervention other than by the subject themselves.
Procedure: Pulsatile Intravenous Insulin Therapy (Humulin R, Novolog)
Endocrinologist reviews patient activation after treatment each week and adjust the amounts of insulin and carbohydrates to be given in the next session
Other Name: Humulin R, Novolog
