The role of “latent autoimmune diabetes in adults” in the structure of diabetes mellitus in young people

Abstract

In the clinical practice of an endocrinologist, verification of the type of diabetes mellitus (DM) in young people is of high clinical significance, since the prescription of treatment depends on this: from the correction of carbohydrate metabolism by a balanced diet to the prescription of oral hypoglycemic drugs and insulin therapy. In rare forms of diabetes mellitus, which include «latent autoimmune diabetes in adults» (LADA), it is not always possible to make a correct diagnosis. This form of diabetes mellitus occupies an intermediate position between type 1 diabetes mellitus and type 2 diabetes mellitus (DM 1 and DM 2) and is often not detected. In this regard, the study of the LADA flow is of great practical importance. Verification of the LADA diagnosis is based on three clinical criteria: adult onset of diabetes; the presence of circulating islet autoantibodies, which distinguishes LADA from T2DM; the absence of an absolute need for insulin when making a diagnosis, which distinguishes LADA from the classic type 1 diabetes mellitus. The main treatment tactics for patients with LADA should be aimed at preserving their own insulin secretion. This requires the timely appointment of insulin therapy. The question of the possibility of using drugs of peripheral action – biguanides and glitazones, which do not cause depletion of β-cells, is discussed, but their effectiveness has not yet been established. The appointment of any secretogens, including sulfonylurea preparations, is contraindicated Quite often, LADA is difficult to diagnose, and the wrong treatment tactics are prescribed. At the moment, there is little data on the effectiveness of different classes of drugs, which leads to further detailed study of this type of diabetes. Currently, there are no special algorithms for LADA treatment

Possibilities of molecular genetic research in the diagnosis of MODY diabetes

“…Motivation and Aim: Most young patients with hyperglycemia are diagnosed with type 1 diabetes mellitus and type 2 diabetes mellitus but up to 10 % of all cases of the disease occur in MODY (Maturity-Onset Diabetes of the Young) diabetes [1]. Diagnosis of the correct type of diabetes mellitus (DM) leads to the appointment of pathogenetic effective therapy, adequate management of pregnancy and the prevention of specific complications.…”
