Rapid-onset type 1 diabetes associated with cytomegalovirus infection and islet autoantibody synthesis.

چکیده
We report the case of a 59-year-old woman who developed rapid-onset type 1 diabetes associated with a marked increase in anti-glutamic acid decarboxylase antibody titer (317.5 U/ml), mild increase in HbA1c level (6.8%), diabetic ketoacidosis, and cytomegalovirus enterocolitis. She was a heterozygote for HLA class II DRB1*0901-DQA1*03-DQB1*0303, and she had HLA class I A24, which may have contributed to the rapid beta cell destruction. Based on the putative molecular mimicry of GAD65 by cytomegalovirus antigen, we hypothesize that the type 1 diabetes in this case was associated with cytomegalovirus infection.

Background: Both genetic and environmental factors are important in pathogenesis of diabetes. Non HLA (Human Leukocyte Antigen) genes such as INS-VNTR and CTLA-4 in addition of HLA genes have influence on genetic susceptibility for diabetes mellitus. In this study the association of +49 A/G CTLA-4 and -23 A/T INS-VNTR polymorphisms with diabetes and their association with islet auto...
متن کاملSimilar genetic features and different islet cell autoantibody pattern of latent autoimmune diabetes in adults (LADA) compared with adult-onset type 1 diabetes with rapid progression.
OBJECTIVE To compare the clinical parameters, C-peptide levels, pattern of islet cell-specific autoantibodies, and prevalence of predisposing genotypes in subjects with latent autoimmune diabetes in adults (LADA) and those with adult-onset type 1 diabetes with rapid progression. RESEARCH DESIGN AND METHODS We evaluated the clinical parameters, C-peptide levels, and islet cell-specific autoant...
متن کاملSingle nucleotide transcription factor 7-like 2 (TCF7L2) gene polymorphisms in antiislet autoantibody-negative patients at onset of diabetes.
CONTEXT There is controversy as to whether type 2 diabetes genetic susceptibility contributes to type 1 diabetes, and it is not known what proportion of islet autoantibody-negative new onset subjects have type 2 diabetes risk alleles. OBJECTIVES We designed this study to evaluate whether two type 2 diabetes-associated single nucleotide polymorphisms (SNPs) of transcription factor 7-like 2 (TC...
متن کاملAn association of autoantibody status and serum cytokine levels in type 1 diabetes.
At onset of type 1 diabetes, the islet autoantibody status of patients has been reported to predict progression of the disease. We therefore tested the hypothesis that the systemic immunoregulatory balance, as defined by levels of circulating cytokines and chemokines, is associated with islet autoantibody status. In 50 patients with recent-onset type 1 diabetes, antibodies to GAD and insulinoma...
متن کاملClinical applications of diabetes antibody testing.
CONTEXT Autoantibodies to glutamate decarboxylase, islet antigen-2, insulin, and zinc transporter-8 are characteristic of type 1 diabetes. They are detectable before clinical onset and define the subgroup of patients with latent autoimmune diabetes in adults. Autoantibody assays are increasingly available to clinicians. This article reviews the prognostic significance of autoantibodies and cons...
