Leptin Levels and Insulin Dependence in Latent Autoimmune Diabetes in Adults.

Latent autoimmune diabetes in adults (LADA) is an autoimmune type of diabetes accounting for up to 10% of all cases of diabetes initially diagnosed as type 2 diabetes mellitus. It has been demonstrated that LADA patients with a lower body mass index (BMI) undergo a faster depletion of beta cell function and require insulin therapy earlier. In this study, we assayed a panel of adipokines (leptin, adiponectin, omentin, resistin, visfatin) and proinflammatory cytokines (interleukin 2, interleukin 6, tumor necrosis factor-α) in 71 LADA patients and tested the association with a number of clinical and immunological features.

Organ-specific antibodies in LADA patients for the prediction of insulin dependence.

Aim Of The Study: The aim of the present study was to define the frequency of organ-specific and non-organ-specific autoantibodies in a cohort of Latent Autoimmune Diabetes in Adults (LADA) patients and to test whether multiple antibodies positivity could be a predictor of early insulin dependence.

Materials And Methods: We enrolled 210 LADA and 210 type 2 diabetes mellitus (T2D) patients. In all subjects anti-islet antigen-2 (IA-2Ab), anti-thyroperoxidase (TPOAb), anti-zinc transporter 8 (ZnT8Ab), anti-nuclear (ANA), anti-parietal cell (APCA), anti-smooth muscle (ASMA), anti-mitochondrial (AMA), anti-liver kidney microsomes (LKM), and anti-reticulin (ARA) circulating antibodies were assessed.

Screening for celiac disease in patients with autoimmune thyroid disease: from research studies to daily clinical practice.

Screening procedures performed in research-setting studies have shown that the prevalence of celiac disease in patients with autoimmune thyroid disease is approximately 4-15 times higher than the general population, thus suggesting that patients with autoimmune thyroid disease should be routinely screened for celiac disease. However, the performance of these screening programs has never been evaluated in everyday, clinical-practice setting. We invited newly diagnosed patients with autoimmune thyroid disease, seen at our Hospital, to participate in a serological screening for celiac disease.

Is there anything to the reported association between Helicobacter pylori infection and autoimmune thyroiditis?

Higher serological prevalence rates of Helicobacter pylori (Hp) infection have been reported in patients with autoimmune thyroiditis (AT), and it has been suggested that monoclonal antibodies against Cag-A positive Hp strains can cross-react with follicular cells of the thyroid gland. We studied the prevalence of AT and thyroid functional status in patients who underwent gastroscopy for dyspeptic symptoms. Patients were tested for TSH, free thyroid hormones, and antithyroglobulin and antithyroperoxidase antibodies (ATPO).
