First-emerging islet autoantibody and glucose metabolism: search for type 1 diabetes subtypes
<p>Objective<br></p><p>Subtypes in type 1 diabetes pathogenesis have been implicated based on the first-appearing autoantibody (primary autoantibody). We set out to describe the glucose metabolism in preclinical diabetes ...
Frailty modeling under a selective sampling protocol: an application to type 1 diabetes related autoantibodies
<p>Abstract<br></p><p>In studies following selective sampling protocols for secondary outcomes, conventional analyses regarding their appearance could provide misguided information. In the large type 1 diabetes prevention ...
Islet Autoimmunity and HLA Markers of Presymptomatic and Clinical Type 1 Diabetes: Joint Analyses of Prospective Cohort Studies in Finland, Germany, Sweden, and the US
<div><p>OBJECTIVE</p><p>To combine prospective cohort studies, by including HLA harmonization, and estimate risk of islet autoimmunity and progression to clinical diabetes.<br></p><p>RESEARCH DESIGN AND METHODS<br></p><p>For ...
Cord-Blood Lipidome in Progression to Islet Autoimmunity and Type 1 Diabetes
Previous studies suggest that children who progress to type 1 diabetes (T1D) later in life already have an altered serum lipid molecular profile at birth. Here, we compared cord blood lipidome across the three study groups: ...
Umbilical cord blood DNA methylation in children who later develop type 1 diabetes
<p><strong>Aims/hypothesis:</strong> Distinct DNA methylation patterns have recently been observed to precede type 1 diabetes in whole blood collected from young children. Our aim was to determine whether perinatal DNA ...
Autoantibodies to N-Terminally Truncated GAD65(96-585): HLA Associations and Predictive Value for Type 1 Diabetes
<p><strong>Objective</strong> <br></p><p>To evaluate the role of autoantibodies to N-terminally truncated glutamic acid decarboxylase GAD<sub>65</sub>(96-585) (t-GADA) as a marker for type 1 diabetes (T1D) and to assess the potential HLA-associations with such autoantibodies.<br></p><p><strong>Design</strong><br></p><p>In this cross-sectional study combining data from the Finnish Pediatric Diabetes Register, the Type 1 Diabetes Prediction and Prevention (DIPP) Study, the DIABIMMUNE Study, and the Early Dietary Intervention and Later Signs of Beta-Cell Autoimmunity (EDIA) Study, venous blood samples from 760 individuals (53.7% males) were analyzed for t-GADA, autoantibodies to full-length GAD<sub>65</sub> (f-GADA), and islet cell antibodies. Epitope-specific GAD autoantibodies were analyzed from 189 study participants.<br></p><p><strong>Results</strong><br></p><p>T1D had been diagnosed in 174 (23%) participants. Altogether 631 (83%) individuals tested positive for f-GADA and 451 (59%) for t-GADA at a median age of 9.0 years (range 0.2-61.5). t-GADA demonstrated higher specificity (46%) and positive predictive value (30%) for T1D than positivity for f-GADA alone (15% and 21%, respectively). Among participants positive for f-GADA, those who tested positive for t-GADA carried more frequently HLA genotypes conferring increased risk for T1D than those who tested negative for t-GADA (77 vs. 53%; P<0.001).<br></p><p><strong>Conclusions</strong><br></p><p>Autoantibodies to N-terminally truncated GAD improve the screening for T1D compared to f-GADA and may facilitate the selection of participants for clinical trials. HLA class II-mediated antigen presentation of GAD(96-585)-derived or structurally similar peptides might comprise an important pathomechanism in T1D.</p>...
Enterovirus Infections Are Associated With the Development of Celiac Disease in a Birth Cohort Study
Enterovirus and adenovirus infections have been linked to the development of celiac disease. We evaluated this association in children who developed biopsy-proven celiac disease (N = 41) during prospective observation ...
Non-HLA Gene Polymorphisms in the Pathogenesis of Type 1 Diabetes: Phase and Endotype Specific Effects
The non-HLA loci conferring susceptibility to type 1 diabetes determine approximately half of the genetic disease risk, and several of them have been shown to affect immune-cell or pancreatic beta-cell functions. A number ...
Consumption of differently processed milk products and the risk of asthma in children
Background Consumption of unprocessed cow's milk has been associated with a lower risk of childhood asthma and/or atopy. Not much is known about differently processed milk products. We aimed to study the association between ...
