Celiac.com 07/04/2019 - There's been some data to suggest that gluten may play a role in diabetes, but there really isn't much data on the role of gluten in type 1 diabetes (T1D), so a team of researchers recently set out to test whether gluten plays a role in type 1 diabetes onset. Specifically, the team wanted to know if a gluten-free diet can decelerate the decline in beta-cell capacity in newly diagnosed non-celiac children with T1D. The research team included Vít Neuman, Stepanka Pruhova, Michal Kulich, Stanislava Kolouskova, Jan Vosahlo, Martina Romanova, Lenka Petruzelkova, Barbora Obermannova, Ondrej Cinek, and Zdeněk Šumník. They are variously affiliated with Charles University in Prague, and the University of Chemistry and Technology in Prague, Czech Republic. For their non-randomized self-selected intervention trial, the team recruited forty-six children, from about 6-13 years old. One group of 26 began a gluten-free diet, while 20 continued on a standard non-gluten-free diet. Main outcomes were the decline in C-peptide area under the curve (AUC) in mixed-meal tolerance tests and the differences in insulin dose, insulin dose adjusted A1c (IDAA1c) and HbA1c at 12 months. Data were analyzed as intention-to-treat by linear regression models adjusted for baseline parameters. The adherence to a gluten-free diet was tested by immunoreactive gluten in stool. Average decrease in C-peptide AUC was 293 vs.484 pmol/L (p=0.3) at 6 months, and 567 vs. 919 pmol/L (p=0.1) at 12 months in the gluten-free diet and control group, respectively. The group that ate a gluten-free diet had a lower insulin dose by 0.22 U/kg/day, lower IDAA1c by 1.5, and lower average HbA1c by 7.5 mmol/mol (p=0.01) after 12 months. Daily carbohydrate intake between the groups was the same. Researchers found immunoreactive gluten in the stool of just 3 patients. Children with type 1 diabetes who ate a gluten-free diet for their first year after diagnosis lower insulin demand and lower HbA1c, although C-peptide dynamics were similar for each group. This is the first study to provide solid data on the connection between gluten intake and type 1 diabetes. The fact that children who follow a gluten-free diet need less insulin is intriguing.

Celiac.com 08/18/2014 - A team of researchers recently set out to better understand the effects of gluten-free diets on obesity. The research team included F.L. Soares, R. Matoso de Oliveira, L.G. Teixeira, Z. Menezes, S.S. Pereira, A.C. Alves, N.V. Batista, A.M. de Faria, D.C. Cara, A.V. Ferreira, and J.I. Alvarez-Leite. They are affiliated with the Departamento de Alimentos, Faculdade de Farmácia, Instituto de Ciências Biológicas, Universidade Federal de Minas Gerais in Belo Horizonte, Brazil. Specifically, the team wanted to determine whether a gluten-free diet can prevent the expansion of adipose tissue, and its consequences. For their study, the team fed C57BL/6 mice a high-fat diet containing either 4.5% gluten (Control) or no gluten (gluten-free). They noted body weight and adiposity gains, leukocyte rolling and adhesion, macrophage infiltration and cytokine production in adipose tissue. The team measured blood lipid profiles, glycaemia, insulin resistance and adipokines. They also assessed the expression of the PPAR-α and γ, lipoprotein lipase (LPL), hormone sensitive lipase (HSL), carnitine palmitoyl acyltransferase-1 (CPT-1), insulin receptor, GLUT-4 and adipokines in epidydimal fat. Gluten-free animals showed less body weight and adipose gain, with no changes in food intake or lipid excretion. These results were associated with up-regulation of PPAR-α, LPL, HSL and CPT-1, which are related to lipolysis and fatty acid oxidation. The team also saw improved glucose regulation, and pro-inflammatory profile-related over-expression of PPAR-γ. Intravital microscopy revealed a lower number of adhered cells in the adipose tissue microvasculature. The over-expression of PPAR-γ is related to the increase of adiponectin and GLUT-4. The results of this study suggest that gluten-free diets can be helpful in reducing fat gain, inflammation and insulin resistance. They suggest that a gluten-free diet should be tested as a way of preventing the development of obesity and metabolic disorders.

Mdki M, Hupponen T; Holm K, Hallstrom O, _Gut_ 1995; Feb 3692) pgs. 239-42 In a study of 238 children and adolescents with insulin dependent diabetes mellitus (IDDM), serum IgA reticulin antibody tests were performed once a year. During the initial testing, within one year of the onset of IDDM, 5 children (2%) were positive. During follow up, 11 of the antibody-negative children (5%) became positive; of these 9 were shown to have silent celiac disease by jejunal biopsies. This study suggests that repeated serological screening and biopsies should be considered to detect late developing, clinically silent celiac disease among patients with IDDM.
