[Susceptibility to chronic HLA-system-associated lymphocytic thyroiditis. Its relationship with insulin-dependent diabetes mellitus]. 1989

I Plensa, and C Pavía, and M G Ercilla

The genetic association between HLA-system and chronic lymphocytic thyroiditis (CLT) related or not to type I diabetes mellitus (IDDM), have been analysed in three groups of children: 16 with CLT, 9 with CLT and IDDM, 11 with IDDM and 200 normal controls. The DQw1 antigen (75% vs 55%) was found associated with CLT, furthermore the observed increase of DR1 and DR2 antigens (37% respectively) is secondary to the linkage disequilibrium that exists between them and DQw1. DR3 antigen (60%) was found significantly increased (p less than 0.001) in CLT patients compared with the control group (24%). In diabetic patients, DR3 and DR4 were found in 85% and 63% respectively (p less than 0.001). The DR3 associated haplotype in CLT patients was different from the diabetic one's. All the diabetics, but one, were DR3-B18 haplotype carriers, but this association was only found in 25% CLT patients. The titre of thyroid microsomal antibodies (MCHA) was more frequent in the patients with DQw1 antigen (MCHA DQw1+ : 1/1072; DQw1- : 1/606). The CLT predisposition in childhood may be influenced by genes located within the HLA-region probably more than one, different from the genes related to IDDM. One of this genes closed to the HLA-DQ region, will be involved in the production of autoantibodies.

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.

D004198	Disease Susceptibility	A constitution or condition of the body which makes the tissues react in special ways to certain extrinsic stimuli and thus tends to make the individual more than usually susceptible to certain diseases.

D006681	HLA-D Antigens	Human immune-response or Class II antigens found mainly, but not exclusively, on B-lymphocytes and produced from genes of the HLA-D locus. They are extremely polymorphic families of glycopeptides, each consisting of two chains, alpha and beta. This group of antigens includes the -DR, -DQ and -DP designations, of which HLA-DR is most studied; some of these glycoproteins are associated with certain diseases, possibly of immune etiology.
