Secondary vaccine failure (SVF) of measles is generally believed to run a milder course of illness than an ordinary course of infection. Severe complications such as central nervous system involvement have rarely been reported. A 12 year old girl, who had received a live attenuated measles vaccine 10 years earlier, developed an encephalomyelitis in the absence of symptoms indicative of ordinary measles such as Koplik spots. Anti-measles hemagglutination inhibition (HI) titer and measles IgM and IgG antibody titers were measured in a commercial laboratory. Measles virus genomic sequence was detected by polymerase chain reaction. Both serum and cerebrospinal fluid (CSF) samples obtained at acute phase already showed extremely high titers of HI (x8192 in serum and x1024 in CSF, respectively) and IgG antibody along with the presence of IgM antibody. Polymerase chain reaction detected the measles virus genomic sequence in the acute phase CSF. The patient's definite history of measles vaccination, high titers of HI and IgG antibodies observed at the very early stage of illness and the clinical course indicated that this patient has an encephalomyelitis due to SVF of measles. It is suggested that measles virus can be a pathogen of encephalitis without symptoms indicative of ordinary measles in individuals who received live attenuated measles vaccines.

Age distribution, history of vaccination against measles, clinical signs and symptoms were investigated among a total of 113 adult measles patients admitted in our hospital between January, 2000 and December, 2002. The maximum body temperature, duration of fever, presence of Koplik spot and exanthema among these adult inpatients were compared with those among 1-to-5-year-old inpatients having measles. Concerning age distribution, the peak was found at the age of 20-24 years. Most of adult inpatients had not contracted measles until then and had not been vaccinated against measles. The infection route was unknown except a small number of inpatients. Clinical signs and symptoms among adult inpatients were about the same of those in pediatric inpatients except a sore throat. Complications occurred in 17 cases out of 113 adult inpatients, 4 of them had encephalitis or acute disseminated encephalomyelitis and the other 4 cases contracted pneumonia. Among the 45 child inpatients, whereas, 23 had complications, 13 of them had pneumonia, 3 contracted otitis media, and an additional 3 suffered from both pneumonia and otitis media. From the results it is reasonably concluded that clinical signs and symptoms among adults impatients with measles are comparable with those of pediatric measles inpatients or slightly severer.

We report a case of acute disseminated encephalomyelitis preceding measles virus infection. Brain magnetic resonance imaging revealed signal intensity abnormalities in the basal ganglia and cortex consistent with acute disseminated encephalomyelitis. Fever and the first Koplik spots appeared 8 and 10 days later, respectively. This case supports the hypothesis that the immune-mediated demyelinating process may occur before the symptomatic phase of a viral infection. Therefore, children without history of infectious disorders should also have acute disseminated encephalomyelitis included in the differential considerations.
