The presence of the antigliadin antibodies in autoimmune thyroid diseases
Abstract
To investigate the presence of the antigliadin antibodies in the patients with Graves' disease and Hashimoto's thyroiditis.
Four hundred patients with autoimmune thyroid disease (280 Graves' disease and 120 Hashimoto's thyroiditis ) were included in the study. The patients with celiac sprue patients were excluded. For the diagnosis of autoimmune thyroiditis, blood levels of thyrotropin (TSH), free thyroxine (FT4), and the titration of thyroid autoantibodies (TgAb and TmAb) were measured, and the thyroid gland was ultrasonographycally evaluated. After the diagnosis of autoimmune thyroid disease was established, the titration of antigliadin antibodies (Ig A and B) were routinely detected.
Twenty two patients (5.5 per cent) with autoimmune thyroiditis had positive antigliadin antibodies. Polyglandular endocrine syndrome was diagnosed in most of these patients.
We claim that polyglandular endocrine syndrome is the commonest cause of positivity of antigliadin antibodies in the patients with autoimmune thyroid disease.
Food is considered as important environmental factor that plays a role in development of Hashimoto's thyroiditis (HT). The goal of our study was to identify food groups, assessed by food frequency questionnaire, that differ in consumption frequency between 491 patients with HT and 433 controls. We also analysed association of food groups with the wealth of HT-related clinical traits and symptoms. We found significantly increased consumption of animal fat (OR 1.55, p < 0.0001) and processed meat (OR 1.16, p = 0.0012) in HT cases, whereas controls consumed significantly more frequently red meat (OR 0.80, p < 0.0001), non-alcoholic beverages (OR 0.82, p < 0.0001), whole grains (OR 0.82, p < 0.0001) and plant oil (OR 0.87, p < 0.0001). We also observed association of plant oil consumption with increased triiodothyronine levels in HT patients (β = 0.07, p < 0.0001), and, association of olive oil consumption with decreased systolic blood pressure (β = − 0.16, p = 0.001) in HT patients on levothyroxine (LT4) therapy. Analysis of food consumption between HT patients with and without LT4 therapy suggest that patients do not tend to modify their diet upon HT diagnosis in our population. Our study may be of relevance to nutritionists, nutritional therapists and clinicians involved in developing dietary recommendations for HT patients.
Background & objectives: Several autoimmune disorders have been reported to be associated with autoimmune thyroiditis and may coexist with other organ-specific autoantibodies. The aim of the present study was to evaluate the presence of tissue transglutaminase (anti-TTG) and glutamic acid decarboxylase (anti-GAD) antibodies in patients suffering from autoimmune thyroiditis as diagnosed by anti-thyroid peroxidase (anti-TPO) antibodies, which may indicate high risk for developing celiac disease or type 1 diabetes mellitus.
Methods: Five thousand children and 2800 adults were screening as part of a general health examination done on a voluntary basis in four different parts of Delhi. A total of 577 subjects positive for anti-TPO antibody constituted the cases. Equal number of age and sex matched anti-TPO antibody negative controls were randomly selected from the same cohort to form paired case control study. The cases and controls were further divided into two groups as follows: group-1 (children and adolescent 18 yr). Serum samples of cases and controls were analysed for thyroid function test (FT3, FT4, and TSH), anti-TTG and anti-GAD antibodies.
Results: A total of 1154 subjects (577 cases and 577 controls) were included in this study. Hypothyroidism was present in 40.2 per cent (232) cases compared to only 4.7 per cent (27) in controls (P
This technical review addresses the state of evidence for celiac disease epidemiology, detection by serologic testing, diagnosis by biopsy, treatment, and outcome. It updates the previous American Gastroenterological Association (AGA) Institute technical review on celiac disease published in 2001.
