Islet-cell antibodies in juvenile diabetes mellitus of recent onset.
Antibodies reacting with human pancreatic islet cells were found by immunofluorescence in the sera of 51 of 105 children with diabetes mellitus of recent onset. These antibodies were of IgG class, and several of them fixed complement and reacted with pancreatic islets of other species. Thyroid microsomal and/or gastric-parietal-cell antibodies were found in only 10 of the patients with islet-cell antibodies, and none of them had adrenal antibodies. These findings contrast with previous reports which have stressed the rarity of islet-cell antibodies in adult diabetics and their occurrence only in patients with other evidence of autoimmune disease.
