AB The authors report two cases of acute myocarditis due to Staphylococcus
aureus in patients with AIDS. There was no history of opportunist
infections in either case but the CD4 lymphocyte levels were very low.
The myocarditis caused acute cardiac failure and death. Histological
examination showed microabscesses filled with Gram positive cocci
throughout the myocardium. Bacteriological studies identified the
Staphylococcus aureus. Staphylococcus aureus myocarditis without
endocardial or pericardial involvement is very rare. It is the result of
septic emboli in the cardiac microcirculation. Bacterial myocarditis has
rarely been diagnosed in HIV positive patients. Both our cases featured
severe cell-mediated immunodeficiency without associated neutropaenia.
The decreased bactericidal activity of the neutrophil polynuclears
and/or a deficit in the immunity mediated by the B-cell lymphocytes in
AIDS could explain the lethal septic complications observed in our two
cases.
