The genetic etiology of Type 1 (insulin-dependent) diabetes mellitus is complicated by the apparent presence of several diabetes susceptibility genetic regions. Type I diabetes in the inbred BioBreeding (BB) rat closely resembles the human disorder and was previously shown to involve two genes: the lymphopenia (lyp) region on Chromosome (Chr) 4 and RT1(u) in the major histocompatibility complex (M
The fundamental first stage of product interaction is through sensory perception, which generates cognitive and affective experiences. Product perception through sensory feedback is a major component in the end user product appraisal that precedes the elicitation of product emotion. Sensory evaluation is connected to a set of concepts including appraisal, concern and goal oriented objective. The i
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
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
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
Autoantibodies to human pituitary cytosol proteins were determined by immunoblotting in sera from patients with hypopituitarism and their relatives. Reactivity to an M(r) 49 000 protein was significantly more frequent in patients (6/21 (28%) P<0.05) as well as in relatives (10/35 (28%) P<0.02) compared with controls (3/44 (6.8%)). Autoantibodies to this particular protein have previously been dete
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
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
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
