Unusual features in a case diagnosed as subacute sclerosing panencephalitis (SSPE).
SSPE is characterised by progressive mental deterioration, myoclonic and similar motor disorders and final severe comatose states, increase of immunoglobuline G in the CSF, strongly elevated antibody titers to measles virus in serum and CSF and typical periodic K-complexes in the EEG. The disease appears commonly in childhood and has a fatal course. Cases with atypical signs have occasionally been reported. The case described in this paper shows a number of uncommon features: late onset, partial remission and stationary course, increased antibody titers to measles virus but relatively low in comparison to others, dissociation of cytoplasmic and nuclear fluorescent antibodies against SSPE brain tissue and an initial increase of antibodies against rubella virus. The patient was treated with isoprinosine. Improvement was observed before the start of this therapy and stabilized while treatment was being continued.
