Intervention to Preserve Beta-Cell Function in GAD Ab-Positive Diabetes
We tested the hypothesis that insulin therapy rather than sulfonylurea (SU) treatment has a preferable outcome to reverse or preserve beta cell function in the patients with diabetes that is called slowly progressive insulin-dependent (type 1) diabetes (SPIDDM) or latent autoimmune diabetes in adult (LADA).
|Study Design:||Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Prevention
- The primary endpoint was insulin-dependency (IDDM: integrated C-peptide values [sigma C-peptide] <4 ng/ml).
|Study Start Date:||January 1996|
|Estimated Study Completion Date:||January 2005|
In a multicenter, randomized, nonblinded clinical study, 4,089 non-insulin dependent diabetic patients were screened for glutamic acid decarboxylase autoantibodies (GADAb). Sixty GADAb-positive non-insulin requiring diabetic patients with duration of diabetes =/<5 years were assigned to either the SU group (n = 30) or the Insulin group (n = 30). Serum C-peptide response to annual oral glucose tolerance tests were followed for 57 mean months. The primary endpoint was insulin-dependency (IDDM: integrated C-peptide values [sigma C-peptide] <4 ng/ml).
