: A link between thyroid dysfunction and diabetes mellitus exist. Uncertainties on the role of glycemic variability on thyroid hormones and TSH concentrations still persist. We want to evaluate the influence of glycemic variability on thyroid hormones and TSH concentrations in patients with type 1 diabetes (T1DM). 77 patients with T1DM on insulin therapy without thyroid dysfunction and 100 healthy controls were evaluated for basal glucose concentrations, HbA1c, thyroid hormone...

Diurnal salivary and plasma cortisol variations are considered valid expression of circadian cortisol rhythmicity. The aim of this study was to assess the reliability of salivary and plasma cortisol evaluating if glycemia and glycemic oscillations may interfere with their concentration.Methods: Forty-seven type 2 diabetic patients and 31 controls were studied for glycemic profile and diurnal salivary and plasma cortisol variations on two contemporary sam...

Hypothyroidism therapy is based on the administration of appropriate dose of L-thyroxine (L-T4). Absorption of L-T4 takes place in the duodenum and upper tract of the small intestine (jejunum), is maximal when stomach is empty, and is affected by a number of gastrointestinal disorders, including Helicobacter pylori–related gastritis, as well as ingestion of drugs, dietary fibers, and herbal remedies. Failure to achieve a good control of disease may be due to malabsorption...

Context: Women with autoimmune Addison’s disease with normally ovulatory cycles but positive for steroid cells antibodies (StCA) have been considered at risk of premature ovarian insufficiency (POI).Design: Thirty-three women younger than 40 years, with subclinical-clinical Addison’s disease but with normally ovulatory menses, were followed-up for 10 years to evaluate the long-term time-related variations of StCA, ovarian function and follicula...
