Evidence for defective immunoregulation in the syndrome of familial candidiasis endocrinopathy.
We studied three children with candidiasis endocrinopathy syndrome, together with their parents and five siblings, to explore the possibility that defective immunoregulation allows autoimmune phenomena to be involved in the pathogenesis of this syndrome. Inheritance of the syndrome appeared to be autosomal recessive. Immunologic abnormalities in this family included hypergammaglobulinemia, selective IgA deficiency, anergy, autoimmune endocrinopathies and active chronic hepatitis. Defective suppressor T-cell function was noted in the two surviving children with clinically apparent disease and in a clinically normal sibling. Analysis of the immunologic abnormalities in the family suggests that defective immunoregulation rather than disordered effector mechanisms may explain the large number of immunologic defects noted. These defects, in turn, may result in the clinical manifestation of the syndrome.
