Complex interaction between HLA DR and DQ in conferring risk for childhood type 1 diabetes

Type 1 (insulin-dependent) diabetes mellitus is associated with HLA DR and DQ factors, but the primary risk alleles are difficult to identify because recombination events are rare in the DQ-DR region. The risk of HLA genotypes for type 1 diabetes was therefore studied in more than 420 incident new onset, population-based type 1 diabetes children and 340 age, sex and geographically matched controls

Glutamate decarboxylase (GAD) autoantibody epitope shift during the first year of Type 1 diabetes

Autoantibodies in Type 1 diabetes patients may differentiate between glutamate decarboxylase (GAD65) cloned from human, mouse and rat with a significant better binding to the human antigen. A subgroup of 15% (27/183) patients showed significantly better binding to rodent than to human GAD65. The aim of this study was to determine whether the autoantibody specificity would remain anti-rodent during

Etiological diagnosis of primary adrenal insufficiency using an original flowchart of immune and biochemical markers

Approximately 70-80% of cases of primary adrenal insufficiency are classified as idiopathic. An effective protocol for the etiological diagnosis of primary adrenal insufficiency is needed to ensure correct patient management. With the aim of developing an algorithm for the etiological diagnosis of primary adrenal insufficiency, we studied 56 Italian patients with nonsurgical primary adrenal insuff

Severe insulin resistance in a patient with type 1 diabetes and stiff- man syndrome treated with insulin lispro

We describe a patient with type 1 diabetes with recurrent diabetic ketoacidosis and severe insulin resistance. Extensive evaluation of the etiology of the insulin resistance did not reveal an etiology, and well over 1000 U of daily insulin did not prevent the ketoacidosis. Her blood glucose and insulin requirements were improved with glucocorticoids and octreotide, but the effects of both of these

Immunology in diabetes : An update

Type 1 (insulin-dependent) diabetes mellitus is strongly associated with autoimmune phenomena connected to the loss of β-cells in the pancreatic islets. Despite considerable progress in our understanding of genetic susceptibility factors and islet autoimmunity preceding the clinical onset of Type 1 diabetes there are considerable gaps in our knowledge. First, the etiology is unclear. It is specula

Association between autoantibody markers and subtypes of DR4 and DR4-DQ in Swedish children with insulin-dependent diabetes reveals closer association of tyrosine pyrophosphatase autoimmunity with DR4 than DQ8

HLA DQA1(*)0301-DQB1(*)0302 (DQ8) and DQA1(*)0501-DQB1(*)0201 (DQ2) are positively and DQA1(*)0102-DQB1(*)0602 (DQ6) negatively associated with IDDM. In DQA1(*)0301-DQB1(*)0302 (DQ8)-positive patients, susceptibility is also mediated by DRB1(*)0401. The aim of the study was to determine the association between HLA-DR4 and DQ and the presence of GAD65, ICA512, and insulin autoantibodies as well as

Visual experience of brand-specific automobile design: Studying appreciation, emotion and comprehension using the VPE framework

This paper presents a qualitative questionnaire study of brand-specific visual product design in the automotive sector. The purpose of the study was to explore the visual product experience of automobile design as perceived by the general public and to analyse those experiences using an emerging framework for visual product experience; VPE. In the study; respondents were asked to assess the design

A simple and rapid microSepharose assay for GAD65 and ICA512 autoantibodies in diabetes

GAD65Ab and ICA512Ab are strongly associated with insulin-dependent (Type 1) diabetes mellitus. A novel, simple radio-antigen binding assay with microSepharose conjugated with monoclonal antibodies specific for human immunoglobulin light chains was developed to provide diagnostic sensitivity and specificity of GAD65Ab and ICA512Ab for Type 1 diabetes. The Receiver Operating Characteristic (ROC) cu
