A two month old Ugandan boy underwent surgery for an obstructive right
ventricular vegetation associated with disseminated Staphylococcus au
reus infection. Both the child and his mother subsequently tested posi
tive for HIV infection. Very little is know about the incidence of end
ocarditis in paediatric patients with AIDS. To our knowledge this is t
he first case reported of disseminated S aureus infection associated w
ith endocarditis and an obstructing vegetation in an HIV positive infa
nt with a structurally normal heart. The initial signs and symptoms fo
r endocarditis were atypical, a reflection of the overwhelming infecti
on in an immunocompromised patient. Severe infections may have an atyp
ical presentation in immunosuppressed patients. AIDS needs to be consi
dered in these patients, especially if they come from populations with
endemic HIV infection.
