  4. 4. Exploring the Grey Zone between Type 1 and Type 2 Diabetes

    Författare :Ekaterine Bakhtadze; diabetes och endokrinologi Genomik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : T1D is most common in children and young adults and is characterized by autoimmune destruction of insulin producing pancreatic beta cells, presence of certain risk genotypes such as HLA-DQB1, INS VNTR, PTPN22 and need of insulin for survival. In adults the same situation is often referred to as Latent Autoimmune Diabetes in Adults (LADA), with age at onset after 35 years and non-insulin requiring at least for 6 month after diagnosis.
