Effect of rifampin on cutaneous hypersensitivity to purified protein derivative in humans.
The effect of rifampin on cutaneous hypersensitivity was studied in 11 tuberculous patients. A suppressive effect was noted in eight patients, five of whom developed a negative response to the strength of purified protein derivative to which they had been shown to be previously sensitive. In one instance complete anergy to purified protein derivative was noted. It appears that rifampin has immu...
متن کاملEffect of rifampin on immunity to tuberculosis and on delayed hypersensitivity to purified protein derivative.
Mice vaccinated with mycobacterial ribonucleic acid (RNA) produced a high immune response and did not develop delayed hypersensitivity to purified protein derivative (PPD), and rifampin had no effect on the immune response. Mice vaccinated with viable H37Ra cells produced a high immune response and did develop delayed hypersensitivity to PPD. Rifampin had no effect on this immune response, but ...

Purified Protein Derivative--PPD.
A 55-year-old physician had a PPD made as part of a clinical evaluation. Laboratory tests were unremarkable and PPD, read in 48 hours, showed an area of induration of 18 mm and an erythema of 51 mm (Panel A). A 2 mm punch biopsy was done in the center of the induration 96 hours after the injection. Histopathology showed an intense perivascular cuffing with macrophages and lymphocytes and edema ...

although recently paradoxical potentiation of antibody titers has been reported (11, 14). Cancer chemotherapists have been concerned for many years that the drugs used in treating cancer might suppress any host immunity to the tumor and actually hasten rather than retard its spread. It was for this reason that the present study was under taken. Briefly, the experimental design consisted of asse...
