History of Changes

Purpose

Children born in Turku, Oulu and Tampere university cities in Finland are screened at birth for HLA alleles that carry increased risk to or protection from development of type 1 diabetes. Children carrying increased risk are followed at 3-12-month intervals for development of diabetes-associated autoantibodies. Children having at least two types of autoantibodies (of the four measured) in at least two consecutively drawn samples are randomized to receive daily intranasal insulin or placebo in a double-blinded 1:1 trial. Hypothesis is that intranasal insulin delays or prevents development of clinical type 1 diabetes. The primary outcome measure is development of clinical diabetes.

Primary Outcome Measures:

Development of clinical type 1 diabetes

Secondary Outcome Measures:

Number and concentration in serum of diabetes-associated autoantibodies (ICA, IAA, GADA and IA-2A)
Responses to intravenous glucose tolerance test
Possible side effects of therapy including hypoglycemia
Changes in serum metabolite patterns (metabolomics)

Estimated Enrollment:	240
Study Start Date:	August 1997
Estimated Study Completion Date:	August 2005

Detailed Description:

Children born in Turku, Oulu and Tampere university cities in Finland are screened at birth for the HLA-DQB1 and DQA1 alleles that carry increased risk to or protection from development of type 1 diabetes. Children carrying increased risk are followed at 3-month intervals until 2 years of age and then at 6-12-month intervals until,15 years of age for development of diabetes-associated autoantibodies (autoantibodies against islet cells, insulin, glutamic acid decarboxylase and IA-2 protein). Children having at least two types of autoantibodies of the four measured in at least two consecutively drawn samples are randomized to receive daily intranasal insulin or placebo in a double-blinded 1:1 trial. Hypothesis is that intranasal insulin delays or prevents development of clinical type 1 diabetes. The primary outcome measure is development of clinical diabetes, but serum concentrations of autoantibodies, responses to intravenous glucose tolerance test and possible side effects of therapy are also closely monitored.
