| polyendocrine deficiency syndrome | <syndrome> Polyglandular deficiency syndrome, associated pathologic dysfunction of several endocrine glands, as in Schmidt's syndrome. (05 Mar 2000) |
| polyendocrine syndrome | <syndrome> Autoimmune disorder (the antigen to which the response is mounted is in the B-cells of the pancreas) in which there is involvement of several organ systems. (18 Nov 1997) |
| polyendocrinopathies, autoimmune | Autoimmune disease affecting multiple endocrine organs. Type I is characterised by childhood onset and mucocutaneous candidiasis, while type II exhibits any combination of adrenal insufficiency (addison's disease), lymphocytic thyroiditis, hypoparathyroidism, and gonadal failure. In both types organ-specific antibodies against a variety of endocrine glands have been detected. The type II syndrome differs from type I in that it is associated with HLA-a1 and b8 haplotypes, onset is usually in adulthood, and candidiasis is not present. (12 Dec 1998) |
