Heat-killed Mycobacterium vaccae vaccine was administered in a 3-dose schedule to 12 HIV-infected adults with CD4 cell counts = 300/mm3.
Local and systemic side effects were monitored.
Delayed-type hypersensitivity to purified protein derivative and Mycobacterium avium sensitin was measured at baseline and after the final dose.
Antibody to aralipoarabinomannin, man-lipoarabinomannin, and a short-term culture filtrate of Mycobacterium tuberculosis were also measured.
Lymphocyte proliferation responses to M avium sensitin and M vaccae sonicate were determined.
Vaccine site induration was maximal at 2 days (median, 6 mm) and no systemic side effects were noted.
Purified protein derivative skin test conversions did not occur.
Changes in CD4 counts and HIV viral load were not significant.
Three (27%) of 11 subjects who completed the trial showed either M avium skin test (n=1) or short-term culture filtrate antibody (n=2) responses.
A three-dose schedule of M vaccae vaccine is safe and well tolerated in adults with early HIV infection and produces detectable immunologic responses in a subset of these subjects.
