Data on clinical, genetic, and immunological aspects of sixty patients with type 2 polyglandular autoimmune disease (PGAD) are presented. The literature on this is reviewed and discussed.
Sera from 300 Italian patients with Addison's disease were collected over a 30 year period. Among these patients, 82% had autoimmune disease, 13% had tuberculosis and 5% had another causal condition. In 59% of the cases, autoimmune disease was associated with the autoimmune manifestations contributing to the description of polyglandular autoimmune disease… (More)
Autoantibodies to steroidogenic enzymes, steroid 17 alpha-hydroxylase (17 alpha-OH), cytochrome P450 side-chain cleavage enzyme (P450scc), and steroid 21-hydroxylase (21-OH), were measured using specific and sensitive immunoprecipitation assays (IPAs) in patients with various forms of autoimmune adrenal disease. Autoantibodies to 17 alpha-OH were detected… (More)
Autoimmune Addison's disease and premature ovarian failure are characterized by the presence of organ-specific autoantibodies. The main adrenal and gonadal autoantigens have been identified and cloned, and the relationship between the autoantibodies detected by immunofluorescence techniques and those detected by the new assays using recombinant autoantigens… (More)
Adrenal autoantibodies characteristic of autoimmune Addison disease are directed towards steroid 21-hydroxylase (21-OH; EC 126.96.36.199). We describe a new assay to measure 21-OH autoantibodies (21-OH Abs), based on immunoprecipitation by the antibodies of 35S-labeled human 21-OH. Using this immunoprecipitation assay (IPA), we detected 21-OH Abs in 42 of 64… (More)
A case of intestinal haemorrhage due to ectopic ulcerated gastric mucosa in Meckel's diverticulum in a young male is reported. The haemorrhage was stopped 5 days after continuous infusion with ranitidine (6 fials in 500 cc of physiological solution X 2). The therapy also proved effective in cases of bleeding ectopic gastric mucosa.
Autoantibodies (Abs) to steroid 21-hydroxylase (21-OH) are a major component of adrenal cortex Abs and are characteristic of autoimmune Addison's disease. We have developed a new method for measuring Abs to 21-OH based on 125I-labeled recombinant human 21-OH produced in yeast. With this assay, 21-OH Abs were detected in 43 of 60 (72%) sera from patients… (More)
Adrenal autoantibodies (ACA) are markers of adrenal cortex involvement in idiopathic Addison's disease. Recently the 21-hydroxylase (21-OH) enzyme has been discovered to be the major autoantigen of the ACA. A potential role of these antibodies in determining adrenal failure by inhibition of the 21-OH has been recently postulated. To test this hypothesis,… (More)
