title: Diagnostic and pathogenetic aspects of subacute sclerosing panencephalitis.
abstract: Subacute sclerosing panencephalitis, usually a rapidly progressive and fatal disease, is a slow virus infection, where measles virus persists in cells of the CNS and in lymphocytes. Four patients, 3 boys and 1 girl, are described, who presented a characteristic disease course, beginning at the age of 12 to 14 years after they had contracted measles infection during infancy or early childhood. The diagnostic criteria including clinical and laboratory CSF findings are summarized, and epidemiologic features related to measles and measles immunization are briefly discussed. In two patients specific measles virus protein antibodies in serum and CSF were analyzed. The results confirm postulated mechanisms for viral persistence in the CNS and suggest in addition a possible role of the viral protein H in the pathogenesis of SSPE.
