Albumin-directed antibodies in diabetes: demonstration of human serum albumin-directed IgM autoantibodies. 1986

I Gregor, and N Iberg, and W Berger, and R Flückiger

Sera of 406 individuals, 174 Type 1 (insulin-dependent) diabetic patients, 125 non-diabetic family members and 107 unrelated control subjects, were screened for the presence of antibodies against glycated albumin. In none of these sera could such antibodies be detected. However, antibodies directed towards monomeric, unmodified human serum albumin were detected in 13 sera. These albumin autoantibodies were of the IgM class, and occurred in sera from nondiabetic persons (0.9-1.6%) and with a five-fold higher frequency in sera from diabetic patients (5.2%). The presence of albumin antibodies was neither related to the presence of diabetic late complications, islet cell antibodies, HLA-status nor duration of diabetes. The albumin antibodies were also found in sera from persons carrying antibodies against mumps (17%) or Epstein-Barr virus.

UI MeSH Term Description Entries
D007075 Immunoglobulin M A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin. Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM
D008297 Male Males
D003922 Diabetes Mellitus, Type 1 A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.

D006031 Glycosylation The synthetic chemistry reaction or enzymatic reaction of adding carbohydrate or glycosyl groups. GLYCOSYLTRANSFERASES carry out the enzymatic glycosylation reactions. The spontaneous, non-enzymatic attachment of reducing sugars to free amino groups in proteins, lipids, or nucleic acids is called GLYCATION (see MAILLARD REACTION).

D017127 Glycation End Products, Advanced A heterogeneous group of compounds derived from rearrangements, oxidation, and cross-linking reactions that follow from non-enzymatic glycation of amino groups in PROTEINS; LIPIDS; or NUCLEIC ACIDS. Their accumulation in vivo accelerates under hyperglycemic, oxidative, or inflammatory conditions. Heat also accelerates the formation of advanced glycation end products (AGEs) such seen with the browning of food during cooking.
