[Endocrinology and interdisciplinary consultation in internal medicine : Illustrated using the example of polyglandular autoimmune syndrome].

Polyglandular autoimmune syndromes encompass several endocrine and nonendocrine autoimmune disorders with variable onset and phenotype. Rheumatoid and gastroenterological symptoms in patients with autoimmune polyglandular syndromes are suggestive of additional rheumatoid gastrointestinal and hepatological autoimmune diseases. Autoimmune gastritis, celiac disease, autoimmune hepatitis, rheumatoid arthritis, Sjögren syndrome, and systemic Lupus erythematodus are of particular clinical relevance. In addition, unspecific rheumatoid and gastrointestinal attendant symptoms of the existing autoimmune endocrinopathy must be considered. Furthermore, certain disorders of polyglandular autoimmune syndromes, e. g., type 1 diabetes are frequently associated with particular gastrointestinal diseases such as small bowel bacterial overgrowth. An optimal patient-centered care of subjects with autoimmune diseases requires a comprehensive differential diagnostic work up and emphasizes the importance of an interdisciplinary cooperation.
