[Interpretation of the results of identification of measles virus antibodies in the serum and cerebrospinal fluid from patients with suspected subacute sclerosing panencephalitis (SSPE)].

Clinical diagnosis of subacute sclerosing panencephalitis+ (SSPE) requires laboratory confirmation relying on an evaluation of immune response in serum and in cerebrospinal fluid (CSF) to measle virus. In our study a comparison of antibody level for this virus by ELISA and haemagglutination inhibition test was made in materials derived from 1396 patients with SSPE, sclerosis multiplex, acute measles++ neuroinfections and other diseases of central nervous system (CNS). Statistical analysis permitted to settle criteria for differentiation of SSPE from remaining diseases of CNS and usefulness for diagnosis of particular methods as well as analysis of results obtained with single sample of serum or CNS. An advantage of ELISA for diagnostic purposes and CSF samples were confirmed.
