Tuberculin skin testing with purified protein derivative (PPD) was found to induce alterations of in vitro measures of cell mediated immunity. T lymphopenia with proportionate decreases of TM and TG cell numbers were observed two days after skin testing. A relative augmentation of TM cells was demonstrated after one week. Peripheral blood mononuclear cells from negative skin responders had normal in vitro reactivity to PPD stimulation suggesting a cutaneous abberation in these individuals. Macrophage dependent depressed PHA reactivity of mononuclear cells was demonstrated two days after skin testing. No change in natural killer cell cytotoxicity was observed. Cytotoxicity was positively correlated to the number of TG cells in the assay.

The treatment with adrenocorticotropic hormone of guinea pigs sensitized with heat-killed tubercle bacilli caused suppression of their skin reactivity to tuberculin. Similar animals treated with saline did not show this change. Normal guinea pigs treated with adrenocorticotropic hormone showed suppression of inflammation, but not necrosis, produced by intracutaneous oil of turpentine. There was slight, but probably not significant, diminution of inflammation during saline administration. Tuberculin complement-fixing antibody titers were not altered by either adrenocorticotropic hormone or saline administration. Adrenocorticotropic hormone produced marked eosinopenia and lymphopenia in guinea pigs.
