AB The amounts of microglia/macrophages, of cells expressing MHC class II
antigen and tumour necrosis factor-alpha (TNF-alpha) were evaluated in
the spinal cord. HIV encephalitis/leucoencephalopathy (as shown by the
presence of MGCs and/or p24 antigen positive cells) was present in 56%
of the cases. Other brain pathology were CMV encephalitis (16%),
lymphoma (6%) and PML (6%); 16% of the patients had non specific
lesions. HIV myelitis was seen in 1 out of 18 cords, which were devoid
of opportunistic infections. Depending on the area involved and severity
of vacuolar changes and inflammation VM was classified as mild in 7
cases, moderate in 2 and severe in 6. No VM was seen in 3 cases. p24
antigen was detected in the cord in 1/18 cases. In all 18 cases the
number of inflammatory cells the expression of MHC II and the amount of
TNF-alpha was higher than in controls; moreover there was correlation
between the severity of VM and the number of microglia/macrophages. On
the other hand, whereas cords without VM showed low levels of TNF-alpha
and microglial/macrophages, cases with VM showed amount of
microglial/macrophages proportional to the severity of VM, whilst
increased expression of TNF-alpha seemed to be correlate more with the
presence of VM than with its severity.
