Central nervous system Alternative names Return to top SSPE; Subacute sclerosing leukoencephalitis; Dawson´s encephalitis Definition Return to top SSPE is a progressive, debilitating, and fatal brain disorder caused by infection with a mutant measles rubeola ) virus (a measles virus that has undergone certain genetic changes or mutations). Causes, incidence, and risk factors Return to top Measles virus usually doesn't cause brain damage, but certain mutant forms can invade the brain, causing severe illness and death. SSPE has been reported in all parts of the world, but in western countries it is considered a rare disease. Fewer than 10 cases per year are reported in the United States, decreasing the frequency of this disease dramatically, following the nationwide measles immunization program. However, in some countries like India, over 20 cases of SSPE per million people are annually reported. SSPE tends to occur several years after having measles ( rubeola ), even though recovery from the illness appears to have been normal. More males are affected than females, and the disease generally occurs in children and adolescents.

Peer Review Status: Internally Peer Reviewed Subacute sclerosing panencephalitis (SSPE) is one of three types of encephalitis that may occur secondary to measles virus. The other two types are 1) an acute encephalitis characterized by lymphocytic infiltrates in meninges and around vessels associated with the acute rash of measles, and 2) a post-measles demyelinating process which is probably an autoimmune hyperallergenic phenomenon. In this tutorial only subacute sclerosing panencephalitis will be discussed. Subacute sclerosing panencephalitis develops following the reactivation of the latent measles virus. Clinically, it is insidious in its onset, and is characterized by progressive motor and mental deterioration with myoclonus. The course usually runs from 1 to 3 years. The frequency of SSPE is about 1 in 1 million, there is a male-to-female ratio of 4:1, and 85% of the cases arise in a rural environment.

    DEFINITION:
    A slow viral infection of the brain characterized by chronic encephalitis caused by a persistent measles viral infection.
    EPIDEMIOLOGY:
    • incidence: rare
      • incidence decreased after immunization initiation in 1963
        • risk 8.5/million cases of natural measles infection
        • risk 0.7/million cases after immunization
      • age of onset:
        • 5-15 years in 85% of cases
        • (5-15 years after a natural measles infection or immunization)

    Diseases linked to vaccines
    "Stacey Berry, of Atherton, Manchester was 13 when she had a booster jab in November 1994. Days later she started having fits, "stopped smiling, and stared into space." She was diagnosed with the brain disease SSPE and given two years to live. She died in November 2000, aged 19. A post mortem examination concluded the disease was a "rare complication" of the vaccine"." Media "It is believe that the administration of Salk vaccine in N Zealand was related to the appearance of SSPE in the community. The idea that an unusual reaction to measles infection is the sole cause of SSPE is not consistent with the observations in N Zealand." SSPE AND SALK VACCINE Belgamwar RB, et al (1997).

Since the introduction of measles vaccines, vaccine-associated SSPE has increased in the USA. Therefore, we should pay attention to SSPE after inoculation with measles vaccine, despite the decrease in the incidence of [wild] measles."

For several decades, the palliative treatment for SSPE has included anticonvulsant therapy and supportive measures (tube feedings and good nursing care especially in patients with advanced disease). Medical literature during the last decade, however, has shown stabilization of disease and delay in clinical progression after therapy with inosine pranobex (oral Isoprinosine); oral isoprinosine combined with intrathecal or intraventricular interferon alpha (up to 50% rate of remission or improvement); oral isoprinosine combined with interferon beta; and intrathecal interferon alpha combined with I.V. ribavirin. However, no controlled studies have been performed. The Food and Drug Administration has added inosine pranobex (Isoprinosine) to its List of Orphan Products Designations and Approvals (1988) for the treatment of SSPE.

    Subacute Sclerosing Panencephalitis, a Measles Complication, in an Internationally Adopted Child
    Daniel J. Bonthius,* Nicholas Stanek,† and Charles Grose*
    *Department of Pediatrics, University of Iowa, Iowa City, Iowa, USA; †Department of Neurology, Medical Associates Clinic, Dubuque, Iowa, USA A healthy 13-year-old boy who had spent the first 4.5 years of his life in an orphanage in Thailand before adoption by an American couple became ill with subacute sclerosing panencephalitis and died several months later. The boy had most likely contracted wild-type measles in Thailand. Measles complications are a risk in international adoptions. Undiagnosed infections in internationally adopted children have been receiving increasing attention throughout the past decade. HIV, hepatitis viruses, Treponema pallidum Mycobacterium tuberculosis , and intestinal parasites frequently complicate such adoptions ( ). Subacute sclerosing panencephalitis (SSPE), a postinfectious neurologic complication of measles, can also occur. We describe a fatal case of SSPE in an internationally adopted child 9 years after he arrived in the United States.
    Case Report
    A 13-year-old boy of Thai descent was referred to the pediatric neurology clinic at the University of Iowa Hospital with cognitive difficulties and a progressive movement disorder. The boy was born in 1984 and spent the first 4 ½ years of his life in an orphanage in Thailand before being adopted by an American couple from Dubuque, Iowa. His adoptive parents were told by the adoption agency that the boy's medical history was unremarkable. No history of measles was reported. At adoption, the child appeared healthy and well nourished, and at no time afterwards did he have an illness suggestive of measles. Shortly after arrival, he displayed a short attention span and easy distractibility, for which he was eventually diagnosed with attention deficit hyperactivity disorder. He was treated with low-dose methylphenidate for several years with good results.

    Clinical features
    a. Onset: 5-20 years of age, predominantly in males. The disease has always been preceded by an attack of measles in the distant past or, occasionally, by measles immunization.

    b. Clinical presentation: personality changes, intellectual deterioration; periodic involuntary movements; decerebrate rigidity, severe dementia

    c. Duration: death usually in several years

    d. CSF changes: elevated gamma globulin; antibody titer elevated to measles

    Pathological changes
    a. Gross pathology: Cortical atrophy, demyelination and ventricular dilatation may all be present; changes are mild and are not diagnostic.

    b. Microscopic pathology: Inclusion bodies in oligodendroglia, neurons and astrocytes; chronic inflammatory reaction (perivascular cuffing by lymphocytes and plasma cells); some neuronal loss, gliosis and demyelination. The entire brain may be involved, but lesions are often more severe in neocortex, white matter, hippocampus, thalamus, ventral brainstem. Ultrastructural changes include paramyxovirus nucleocapsid tubules characteristic of measles virus in the inclusion bodies.
    This low power microscopic view shows perivascular cuffing in a case of subacute sclerosing panencephalitis, with mononuclear cells clustered around a vessel.

It is a late manifestation of measles virus infection, developing between usually 6 and 12 years after natural measles infection. Cases can also follow immunization with measles vaccine but at a lesser frequency than after natural measles. The annual incidence is about 1 per million. It is believed that measles immunisation significantly reduces the risk of developing SSPE. Males are more commonly affected, as are those living in rural areas. Mortality is very high. Those who survive do so with considerable intellectual and also physical impairment. The precise sequence of events that results in the development of this disease in a tiny proportion of the population is not known. The great majority of children who develop SSPE are known to have had an attack of classical measles, usually many years before. Over 50% of cases have had the disease at the unusually early age of under two years. The onset of the illness is insidious, the first signs are behavioural disturbances or a decline in school performance. Not infrequently the family are told that the cause for these behavioural or school problems is "psychological". Progression of the illness will vary from child to child but evidence that this is a more serious illness usually begins with loss of motor control and co-ordination. This often starts with characteristic jerking movements which may at first appear as clumsiness. These jerking movements are known as myoclonic seizures. Grand mal (also called tonic-clonic) seizures may also occur. As the condition worsens problems with swallowing and speech develop and vision may be impaired.

    Definition
    Subacute sclerosing panencephalitis is a rare, progressive brain disorder caused by an abnormal immune response to the measles virus. Description This fatal condition is a complication of measles, and affects children and young adults before the age of 20. It usually occurs in boys more often than in girls, but is extremely rare, appearing in only one out of a million cases of measles. Causes and symptoms Experts believe this condition is a form of measles encephalitis (swelling of the brain), caused by an improper response by the immune system to the measles virus. The condition begins with behavioral changes, memory loss, irritability, and problems with school work. As the neurological damage increases, the child experiences seizures, involuntary movements, and further neurological deterioration. Eventually, the child starts suffering from progressive dementia . The optic nerve begins to shrink and weaken (atrophy) and subsequently the child becomes blind. Diagnosis Blood tests and spinal fluid reveal high levels of antibodies to measles virus, and there is a characteristically abnormal electroencephalogram (EEG), or brain wave test. Typically, there is a history of measles infection two to ten years before symptoms begin.
