[Pathology of the internal organs and central nervous system in acquired immunodeficiency syndrome (with special reference to opportunistic infections)].
Extracerebral and cerebral pathology in AIDS (with particular emphasis on the opportunistic infections). The Authors present the extracerebral pathology of 27 cases of AIDS observed at the Department of Pathology of Milan and the cerebral pathology of 80 cases of AIDS collected by three Institutes (Department of Pathology of Milan, Department of Pathology of Rimini and Department of Neuropathology of Münster) with particular emphasis on the pathology of the opportunistic infections. In the adults' group, the most frequent infections are the protozoan ones (T. gondii) followed with equal incidence by the viral and fungal diseases. In the pediatric group the viral diseases are the most frequently seen. Almost all of the adults show multiple infections in the same organ or in different organs. Diffuse lesions with heavy pathologic fields were observed also without tissue reaction. As to cerebral pathology AIDS' patients with opportunistic infections show focal symptoms, whereas the so called "subacute microglial encephalitis" generally appears as a demential syndrome. In cases with progressive multifocal leukoencephalopathy JC virus was always found and in one case also SV 40 - and BK virus. The diffuse demyelinization in some cases of HIV-Encephalopathy is aspecific. In HIV-positive newborns with cerebral signs, the lesions are characterized by oedema, spongiosis and microcalcifications of the basal ganglia; these are aspecific lesions which can be found in toxic and infectious encephalopathies.
