The purpose of this study is to determine whether type I diabetics with carnitine deficiency exhibit increased numbers of hypoglycemic (low blood sugars) events and if unrecognized hypoglycemia occurs during continuous 72-hour glucose monitoring. If they are determined to have unrecognized hypoglycemia, then oral carnitine supplementation will be given to those subjects and they will be reassessed for the number of hypoglycemic events in a 72-hour glucose monitoring.

Drug: Carnitine (drug) |
Study Type: | Observational |
Study Design: | Natural History, Longitudinal, Defined Population, Prospective Study |
Official Title: | Correlation Between Carnitine Deficiency and Hypoglycemic Events in Type I Diabetes; Effects of Carnitine Supplementation on Hypoglycemic Events in Type I Diabetes |
Estimated Enrollment: | 200 |
Study Start Date: | October 2004 |
Hypoglycemia is a clinical marker of carnitine deficiency. Thus carnitine may compound the risk of hypoglycemia for children on insulin therapy. Currently, one of the limitations in the management of diabetes is hypoglycemia. The problem of hypoglycemia is of even greater significance in the pediatric population because children have smaller glycogen stores.
In this study, we will determine if there is a group of children with increased frequency of hypoglycemia and carnitine deficiency. If there is a correlation from the initial 200 children, we will compare two groups of type I diabetic children between the ages of 7 to 21 years. We will take 20 children with the highest carnitine levels (found in a previous study) and 20 children with the lowest carnitine levels and perform continuous glucose monitoring for a 72-hour period. Those who have at least one episode of hypoglycemia will be asked to undergo repeat testing, after a 2-week period of oral carnitine supplementation. Supplementation will start at 50 mg/kg body weight for the first week and then increase to 100 mg/kg body weight the second week. Laboratory studies obtained at baseline include Hemoglobin A1c, carnitine panel, and lipid panel. These will be repeated prior to the second continuous glucose monitoring. Insulin doses will not be changed between glucose monitoring sessions. A comparison will be made between individuals with hypoglycemia, to see if the number of hypoglycemic events has decreased.
