Abstract
Even before 15 years ago, type 1 diabetes mellitus was rated as a disease affecting children, adolescent and young adults. New knowledge about autoimmune insulitis, the possibilities to investigate routinely plasma C-peptide levels and specific islet antibodies have shown, that type 1 diabetes can affect patients in any age as classical type 1 or LADA.
The authors are reporting about the woman, who manifested type 1 diabetes in her 97 years. Her BMI was 22,9 kg/m2, C-peptide plasma level 276 pmol/l and plasma level of specific islets antibodies was significantly positive: GADA 250 IU/ml and IA2A 79,92 IU/ml.
According to our knowledge, our patient is the case of the oldest manifestation of type 1 diabetes proved by levels of specific antigens and plasma C- peptide.
