AB We attempted to isolate HIV from post-mortem tissues (CSF, spleen,
spinal cord, brain and lymph node) of 64 patients. The overall isolation
rate was low (48%) compared to a rate of 95% from peripheral blood
mononuclear leucocytes (PBMC's) from the same patients when they were
alive. This difference appeared to be due to several factors including
delay post death in collecting the tissues, the tissue site and the
pathologist who performed the post-mortem. Usually the AZT
susceptibility of the isolate from the postmortem material was the same
as the PBMC isolate. However, in some patients whose PBMC isolate had
reverted to AZT sensitivity after cessation of therapy, virus in some
tissues remained resistant. In addition, patients whose PBMC isolate
first became resistant to AZT at a time close to their death still had
sensitive virus in some tissues. These results will be discussed in the
light of our current understanding of the pathogenesis of HIV.
