[Changes in the level of humoral response for measles virus in patients with subacute sclerotic panencephalitis during 1984-1989]. / Zmiany w poziomie odpowiedzi humoralnej dla wirusa odry u chorych na podostre stwardniejace zapalenie mózgu w latach 1984-1989.

Immunological response to measles virus in serum and cerebro-spinal fluid of 338 patients with subacute sclerotic panencephalitis (SSPE) during the years 1984-1989, was investigated. It was found that mean titer and distribution of results of antibody determination by the hemagglutination inhibition (OZHA) method in patients sera are visibly differing during consecutive years of investigation. Analysis of these parameters in determination by the immunoenzymatic methods (ELISA) has shown their higher stability. Also results of determinations of IgG concentration in sera of patients with SSPE did not demonstrate significant differences between consecutive years of investigation. Systematic decrease of mutual relation between antibodies to measles virus detected by ELISA and OZHA was found. Analysis of local synthesis of antibodies to measles virus in the central nervous system has revealed that it most strongly expressed by hemagglutinin.
