AB The polymerase chain reaction (PCR) was used to amplify a 149 base-pair
region of the cytomegalovirus (CMV) genome and a 551 base-pair region of
the HIV-1 proviral long terminal repeat (LTR) present in DNA extracted
from post-mortem tissue. Multiple tissues (n = 116) obtained from 16
patients which were subjected to PCR were also subjected to cell culture
and histopathological analyses. One hundred and seven samples (92%)
contained CMV DNA and 66/116 (57%) contained HIV proviral DNA at a level
of > or = 10 genomes. Both viruses were detected in 60/116 (51.7%) of
samples, with co-infection most frequent in the lung (69%). Cell culture
for CMV detected 9.3% of the PCR-positive samples, whilst histology
identified CMV inclusions in 15.9% of samples, all of which were CMV
PCR-positive. CMV was most frequently detected in adrenal and lung
tissues by histology. These results show that co-infection with CMV and
HIV is a common occurrence in organs from AIDS patients and provide
further evidence for a role of cytomegalovirus in the pathogenesis of
AIDS.
