  1. Glutamate decarboxylase antibodies in non-diabetic pregnancy precedes insulin-dependent diabetes in the mother but not necessarily in the offspring.

    Article - En anglais

    We studied the risk for diabetes of glutamate decarboxylase (GAD65Ab) and islet cell (ICA) autoantibodies in non-diabetic pregnant mothers and their children.

    Pregnancy and cord blood sera were collected in 1970-87 from about 35.000 mothers who delivered a child in the city of Malmö, Sweden.

    A total of 42 mothers were identified in 1988 who, 1-18 years after their pregnancies, had developed either insulin-dependent (n=22) or non-insulin dependent (n=20) diabetes mellitus.

    First, in 123 pregnant mothers selected as controls, 0.8% had GAD65Ab and 0.8% ICA.

    Second, among the mothers with non-insulin dependent diabetes, 7/20 (35%) had GAD65Ab eight months to 13 years, 10 months before clinical diagnosis.

    Third, in mothers who later developed insulin-dependent diabetes, 12/22 (55%) had GAD65Ab and 10/22 (45%) had ICA in pregnancies preceding the clinical diagnosis by 13 months to 9 years, 4 months.

    In 1996, none of the children born to the 42 mothers have developed diabetes.

    GAD65Ab and ICA in non-diabetic pregnancies may predict insulin-dependent diabetes in the mother but not necessarily in the offspring.
