An autoimmune attack that is destroying you beta cells is underway. But you are still making a fair amount of your own insulin, so you won't need to inject much at this stage. Be aware, though, that the c-pep will fall over time as you become fully insulin dependent. Furthermore, GAD65 autoantibody-specific epitopes were also analyzed using GAD65/GAD67 chimeric constructs. Results: The prevalence of IAA, IA-2icA, and ZnT8A in nGADA-positive patients was 26, 15, and 19%, respectively, which was significantly higher than that in nGADA-negative type 2 diabetes (2, 2, and 2%; P < 0.0001). Alternative Name (s) IA-2 Antibody, Panel, Diabetes Antibody Panel, Glutamic Acid Decarboxylase-65 Antibody Panel, Insulin Autoantibody, Panel. GAD-65 antibodies are detected in 20% of diabetic twins who remain disease-free for long periods of time and in 8% of healthy individuals.

GAD65 autoantibody also serves as a marker of predisposition to other autoimmune disease that occur with type 1 diabetes, including thyroid disease (eg, thyrotoxicosis, Grave disease, Hashimoto thyroiditis, hypothyroidism), pernicious anemia, premature ovarian failure, Addison disease, (idiopathic adrenocortical failure) and vitiligo. It is advised that blood for IAA testing be drawn before insulin therapy is initiated. For the IAA result to be valid, the patient must not be insulin treated for more than one week.

En intressant patentansökan (PCT/SE20 18/050904) är nu i nationell fas of the initially occurring autoantibody related to the autoimmune disease in autoantikroppar; mot insulin: IAA, mot GAD65: GADA, mot IA-2: IA-2A, 

All sera were tested for their reactivity to GAD65, GAD67, and IA-2 at onset and five years later. IA-2 Autoantibody (IA-2 Ab, Insulinoma associated antigen 2) Autoantibodies to pancreatic beta cell antigens are important serological markers of type 1 diabetes mellitus (type 1 DM). The antigens recognised by these antibodies include insulin, glutamic acid decarboxylase (GAD65 kDa isoform) and an islet cell antigen IA-2 or ICA-512. GAD65 and IA-2 autoantibodies, are associated with impaired or diabetic glucose tolerance in an adult regional population.

Combined analysis of GAD65 and ICA512(IA-2) autoantibodies in organ and non-organ-specific autoimmune diseases confers high specificity for insulin-dependent diabetes mellitus. There is evidence that insulin-dependent diabetes mellitus (IDDM) may develop in association with other non-beta-cell-specific autoimmune diseases.

7 This is consistent with the hypothesis that IDDM is an autoimmune disease and that autoantibody production is an early step in the development of IDDM. 8 Autoantibodies can be detected in many cases prior to the onset of glucose intolerance. Insulin therapy involves injecting insulin just under the skin. You should rotate injection sites to avoid skin irritation. Some types of insulin are meant to act quickly and last for a short time.

In conjunction with family history, HLA-typing and measurement of other islet cell autoantibodies (glutamic acid decarboxylase [GAD65] antibody and islet cell antigen 2 antibody [IA-2]), insulin autoantibody testing helps predict the future development of type I diabetes in asymptomatic children, adolescents, and young adults.

Autoantibodies against insulin, GAD65, and IA-2 were measured in 13 377 children who were followed for 15 years. The frequencies of autoantibody analysis varied among the studies, but were conducted at least twice in the first 2 years after birth, then every 1 to 3 years ( 5 ).

Persons with LADA typically have low, although sometimes moderate, levels of C-peptide as the disease progresses. Test Id: Inab Insulin Antibodies, Serum.
