Standardized tests for insulin autoantibodies (IAA) or GAD65 (GADA) have made it possible to demonstrate that the disease is triggered often during the first years of life. Several non-HLA genetic factors either contribute to the genetic etiology or to the progression toward the clinical onset of the disease. The disease may be diagnosed at any age but only in individuals who have certain HLA-DR-DQ-susceptibility haplotypes. The classical symptoms are polyuria (frequent urination), polydipsia (increased thirst), polyphagia (increased hunger), and weight loss. The subsequent lack of insulin leads to increased blood and urine glucose. Type 1 diabetes, formerly known as juvenile diabetes or insulin-dependent diabetes, results from the specific autoimmune destruction of the pancreatic islet beta cells.

Åke Lernmark, Shehab Alshiekh, in Encyclopedia of Immunobiology, 2016 Abstract Numerous metrics (costs, patient outcomes, etc.) demonstrate that specialists (endocrinologists) provide more effective care for those with T1DM than nonspecialists. Significant advances in terms of disease management, afforded by technological innovations related to insulin analogues and more, set the foundation for marked reductions in hemoglobin A 1c (HbA 1c) and improved diabetes care. There is a growing appreciation that T1DM, rather than being a singular disease, may be a heterogeneous disorder with a common phenotype at clinical presentation/diagnosis. Įxtensive efforts continue to be directed at preventing and reversing the disease, but although there has been progress toward this goal, at present there is no universally accepted means for doing so in a public health care setting.The risk for the disease can be ascertained through a combination of immunologic, genetic, and metabolic markers of disease. The long-held model describing the natural history of T1DM has been extensively readdressed, and there is a greater appreciation for the disorder's heterogeneity in pathogenesis and symptomatic presentation. The pancreas of T1DM patients possesses an islet immune infiltrate derived from a variety of immunologic phenotypes, is reduced in size and weight, and is subject to unusual exocrine features. The disorder is clearly polygenic (over 40 loci impacting susceptibility identified to date), yet over half of disease susceptibility for T1DM is provided by the major histocompatibility complex (MHC). Throughout the globe, the incidence of T1DM is increasing at 3% to 5% per year.

Type 1 diabetes mellitus (T1DM) is a disorder resulting from a chronic autoimmune destruction of the insulin-producing pancreatic beta cells.
