Bioimpedance phase angle indicates catabolism in Type 2 diabetes
Aims Body cell mass is directly proportional to the bioimpedance phase-angle which is an indicator of the amount of electrical charge that cell membranes can hold and is an index of cellular health and function. To evaluate whether the bioimpedance phase angle is relevant for indicating catabolism in people with diabetes and whether it discriminates between people with diabetes receiving different types of therapy. Methods A cross-sectional study was performed in 182 people with Type 2 diabetes and 107 age- and BMI-matched control subjects. The phase angle was measured at 5, 50 and 100 kHz using multifrequency bioimpedance analysis. The phase angles were compared among different diabetes th…
Autoimmune polyglandular syndrome type 2 shows the same HLA class II pattern as type 1 diabetes†
Autoimmune polyglandular syndrome (APS) type 2 is defined by the manifestation of at least two autoimmune endocrine diseases. Only few data exist on genetic associations of APS type 2. In this controlled study, 98 patients with APS type 2, 96 patients with type 1 diabetes (T1D), and 92 patients with autoimmune thyroid disease, both as a single autoimmune endocrinopathy, were tested for association with alleles of the human leukocyte antigen (HLA) class II loci DRB1, DQA1, and DQB1. Patients with APS type 2 had significantly more often the alleles DRB1*03 (P(c) < 0.0001), DRB1*04 (P(c) < 0.000005), DQA1*03 (P(c) < 0.0001), and DQB1*02 (P(c) < 0.05), when compared with controls.

Increased Familial Clustering of Autoimmune Thyroid Diseases
Data regarding familial prevalence and recurrence risk ratio of autoimmune thyroid diseases (AITD) in Germany are lacking. The data from 179 German families of AITD patients encompassing 1 229 relatives were collected using standardized clinical and laboratory diagnostic criteria. Of this large collective, 86 AITD index cases with their 139 children and 106 AITD index cases with their 157 siblings were included. The familial prevalence was estimated by the recurrence risk ratio. This quotient indicates whether first degree relatives display an increased risk for developing AITD, compared with the general population. AITD were present in 14 of children and 15 of siblings of patients with AIT…
