Immunologic competence in adults following thymic irradiation in infancy.
Removal of, or irradiation to, the thymus during the neonatal period in man has resulted in no reported adverse effects on cellular immunity, although thymectomy in neonatal experimental animals is known to produce profound immunological disturbances. Adverse effects in humans may not be recognized until several decades have passed. The immunological capabilities of 7 adults with histories of thymic irradiation as infants were evaluated; normal tests results indicated intact immune systems in all cases. The 3 women tested, however, had abnormal clinical histories, including 2 with multiple tumors and 1 with chronic mucocutaneous candidiasis.
