The relationship between fluorescent, agglutinating, and precipitating antibodies to Candida albicans and their immunoglobulin classes.

A parallel study of fluorescent, agglutinating, and precipitating antibodies to Candida albicans revealed that precipitating antibodies belong to the IgG class, whereas agglutinating antibodies reside in the IgG, IgM, and IgA classes. The three types as well as the three classes of antibodies were found in Candida endocarditis and mucocutaneous candidiasis. Immuno-absorption studies suggest that the three serological tests estimate antibodies to mannan determinants of Candida albicans.

Immunopathology of oral leukoplakia.

The lymphocyte transformation test was performed with autologous saline homogenates of leukoplakia. A negative correlation was established (P<0.05) between the (14)C thymidine uptake of lymphocytes in vitro and the non-pyroninophilic mononuclear cell infiltration in biopsies. A depression of lymphocyte transformation was revealed in patients with carcinoma or carcinoma in situ and some with epithelial atypia, as compared with those showing only hyperkeratosis and to a less extent those with acanthosis. A corresponding depression was not found when lymphocytes were stimulated with phytohaemagglutinin, Candida albicans or Herpes simplex antigens. The Pyroninophilic cell count was raised in biopsies with carcinoma or carcinoma in situ and in some with epithelial atypia or acanthosis. These result suggest that in leukoplakia the carcinomatous transformation may be associated with some immunological changes.

Adrenal function during topical oral corticosteroid treatment.

Plasma cortisol (hydrocortisone) levels were measured in 42 subjects before and during administration of topical oral corticosteroids. Topical administration of 0.3-0.4 mg. of betamethasone disodium phosphate daily caused partial suppression of adrenal function in 8 out of 10 subjects tested. The adrenal function remained normal in 14 patients treated with 10 mg. of hydrocortisone hemisuccinate daily for periods of up to three years. Betamethasone 17-valerate also failed to cause adrenal suppression in doses of 0.4 mg. per day in 17 patients. The adrenal glands failed to respond normally to stimulation with Synacthen (tetracosactrin) in selected subjects with depressed plasma cortisol levels. Therapeutic doses of topical oral hydrocortisone hemisuccinate and betamethasone 17-valerate may be used in adults with oral lesions without fear of affecting adrenal function. Betamethasone disodium phosphate, however, should be avoided, as it may cause adrenal suppression.
