Celiac Disease in Children, Diabetes Mellitus, Type I, Screening
Conditions
Brief summary
Early diagnosis of type 1 diabetes and celiac disease is very useful, allows early therapy and prevents deaths from the onset of diabetic ketoacidosis. This is a pilot study on screening of autoantibodies of type 1 diabetes and celiac disease in tuscany patients. The study aims to evaluate the concordance between the screening results obtained using two different matrix (blood drop spots on card and serum) in the search for autoantibodies for celiac disease and for type 1 diabetes. Moreover, it will be evaluated the feasibility and acceptability of the screening on a sample of the population enrolled in the territory through the participation of pediatricians.
Interventions
The blood sample will be drawn by venipuncture during clinical routine. The serum will be tested for coeliac or diabetes 1 auto-antibodies, using Elisa test.
A finger prick will be used to collect Dried blood Spot (DBS) on a special card. The eluted blood spot will be tested, for coeliac and diabetes 1 auto-antibodies, using the same method used for serum, and the same cut-offs for positivity and negativity (Elisa tests)
