Fakhfakh R, Haddouk S, Hadj Hamida YB, Kamoun T, Ayed MB, Hachicha M, Masmoudi H: Pancreatic autoantibodies in Tunisian children with newly diagnosed type 1 diabetes. Pathol Biol. 2008 May;56(3):130-2. Epub 2008 Jan 4.
We analyzed 86 children with newly diagnosed type 1 diabetes for antibodies to islet cells (ICA), glutamic acid decarboxylase (GADA), second-islet antigen (IA-2A), and insulin (IAA) in order to evaluate the prevalence of immune-mediated type 1 diabetes, as well as to recognize which autoantibody combination is more frequently associated with the disease. A positive result for one or more diabetes-related antibodies evaluated was found in 78 children (90.7%). With regard to single autoantibody testing, ICA were found to be positive in 49 patients (57%), GADA in 56 (65.1%), IA-2A in 37 (43%), and IAA in 43 (50%) patients. Combining the determination of at least two autoantibodies, GADA and/or IAA were better detectable than other antibody combination, being positive in 70 patients (81.4%). GADA and IA-2A represent also a useful screening combination; being positive in 65 patients (75.6%). Our data indicate that the vast majority of cases of type 1 diabetes in children may be considered as immune-mediated and that multiple autoantibody analysis improves identification of the disease. |
