Abstract
Measles is a vaccine-preventable illness. Nevertheless, in recent years, measles is still endemic and epidemic in both the developed world and the developing world. The public perception of measles in the past was that it was not a big deal. However, measles is associated with a number of complications which can be places in three categories which are: acute(diarrhea, otitis media, pneumonia, encephalitis, seizures, and death) and delayed-subacute sclerosing panencephalitis (SSPE) and post-measles immune amnesia. Contrary to the beliefs of the anti-vaccine lobby, measles is bad. In acute measles, the death rate is 1-3 per 1000 and the risk of encephalitis is 1 per 1000. Relatively recent investigations indicate that SSPE is considerably more common than previously believed. The worldwide contribution of post-measles immune amnesia to morbidity and mortality is likely to be huge. In exposure situations, two doses of measles vaccine will prevent 99% of cases. Presently in the United States, the first dose is given at 12 through 15 months of age. The second dose is most often administered at 4 through 6 years of age. In my opinion, the second dose of measles vaccine should be given 4-6 weeks after the first dose rather than at 4-6 years of age. Children who don't have antibody to measles should not travel to risk areas.

Abstract
In subacute sclerosing panencephalitis (SSPE) the persistence of measles virus (MeV) may be related to the altered immune response. In this study, cytokine responses of lymphocytes and monocytes were evaluated in SSPE compared to controls with non-inflammatory (NICON) and inflammatory (ICON) diseases. Patients with SSPE (n = 120), 78 patients with ICON and 63 patients with NICON were included in this study. Phenotypes of peripheral blood mononuclear cells (PBMC) have been analyzed by flow cytometry. CD3 and CD28, and S. aureus Cowan strain I (SAC) stimulated and unstimulated cells were cultured and IL-2, IL-10, IFN-γ, IL-12p40, IL-12p70 and IL-23 were detected in supernatants by ELISA. MeV peptides were used for MeV-specific stimulation and IFN-γ secretion of PBMC was measured by ELISPOT. Spontaneous and stimulated secretions of IL-10 were lower in SSPE compared to both control groups. T cell stimulation induced lower IFN-γ production than ICON group, but higher IL-2 than NICON group in SSPE. Stimulated PBMC produced lower IL-12p70 in SSPE and had decreased CD46 on the cell surface, suggesting the interaction with the virus. IFN-γ responses against MeV peptides were not prominent and similar to NICON patients. The immune response did not reveal an inflammatory activity to eliminate the virus in SSPE patients. Even IL-10 production was diminished implicating that the response is self-limited in controlling the disease.

Abstract
Subacute sclerosing panencephalitis (SSPE) is a progressive, lethal complication of measles caused by particular mutants of measles virus (MeV) that persist in the brain despite high levels of neutralizing antibodies. We addressed the hypothesis that antigenic drift is involved in the pathogenetic mechanism of SSPE by analyzing antigenic alterations in the MeV envelope hemagglutinin protein (MeV-H) found in patients with SSPE in relation to major circulating MeV genotypes. To this aim, we obtained cDNA for the MeV-H gene from tissue taken at brain autopsy from 3 deceased persons with SSPE who had short (3-4 months, SMa79), average (3.5 years, SMa84), and long (18 years, SMa94) disease courses. Recombinant MeVs with a substituted MeV-H gene were generated by a reverse genetic system. Virus neutralization assays with a panel of anti-MeV-H murine monoclonal antibodies (mAbs) or vaccine-immunized mouse anti-MeV-H polyclonal sera were performed to determine the antigenic relatedness. Functional and receptor-binding analysis of the SSPE MeV-H showed activity in a SLAM/nectin-4-dependent manner. Similar to our panel of wild-type viruses, our SSPE viruses showed an altered antigenic profile. Genotypes A, G3, and F (SSPE case SMa79) were the exception, with an intact antigenic structure. Genotypes D7 and F (SSPE SMa79) showed enhanced neutralization by mAbs targeting antigenic site IIa. Genotypes H1 and the recently reported D4.2 were the most antigenically altered genotypes. Epitope mapping of neutralizing mAbs BH015 and BH130 reveal a new antigenic site on MeV-H, which we designated Φ for its intermediate position between previously defined antigenic sites Ia and Ib. We conclude that SSPE-causing viruses show similar antigenic properties to currently circulating MeV genotypes. The absence of a direct correlation between antigenic changes and predisposition of a certain genotype to cause SSPE does not lend support to the proposed antigenic drift as a pathogenetic mechanism in SSPE.

Abstract
Subacute sclerosing panencephalitis (SSPE) is a progressive neurodegenerative disease with high mortality and poor prognosis. This is caused by persistent defective measles virus infection. Clinical presentations are variable including behavioral-cognitive change, myoclonic seizure, visual problem, spasticity or abnormal movement. The authors report a case of 10 year-old boy, previously healthy with complete immunization, presenting with frequent myoclonic jerks, abnormal movements, spasticity and altered mental status. Electroencephalographic (EEG), magnetic resonance imaging (MRI), and laboratory findings are typical for SSPE.

Abstract
Subacute sclerosing panencephalitis (SSPE) is a progressive neurological disorder of childhood and early adolescence caused by persistent defective measles virus. Clinical manifestations appear many years after the acute measles infection. The incidence of SSPE has substantially declined after the introduction of an effective vaccine. We report a case of a child with SSPE that began with atonia, dysarthria, and intellectual deterioration without the presence of any particular EEG anomalies. We have reported this girl who was affected by this severe affliction in the hope that, because of the rarity of SSPE, it would not go undiagnosed.

Abstract
Genetic susceptibility to infectious diseases can be explained by nucleotide alteration (mutation, polymorphism, etc.) of genes encoding molecules involved in the entry of or the immune response to microorganisms. We have conducted studies on host genetic factors for the development of mycobacterial infections and subacute sclerosing panencephalitis (SSPE) in the past decade. First, we identified autosomal dominant IFN-gamma receptor deficiency as a predominant genetic basis of patients with bacille Calmette-Guérin osteomyelitis in Japan. Second, by gene-based association analysis of 21 candidate genes, it was suggested that genetic variants of IL-12 receptor beta1 gene (IL12RB1) confer genetic susceptibility to tuberculosis, and are associated with the progression of the disease in Japanese. Third, we demonstrated that variants of several genes encoding molecules associated with innate immunity (MxA and TLR3 genes) and acquired immunity (IL4 and programmed cell death 1 [PD1] genes) were associated with the development of SSPE. Immunogenetical approaches to infectious diseases would help us to evaluate the risk for disease development and progression, individualize prevention and treatment strategies, and create new therapies.

Abstract
This study was conducted to observe the impact of measles vaccination on the epidemiology of subacute sclerosing panencephalitis (SSPE) in the post measles vaccination era. This is a retrospective study from a tertiary care hospital, covering a ten year period starting a decade after the introduction of the national measles immunization programme in India. We analyzed 458 serologically confirmed SSPE cases. These patients had a high cerebrospinal fluid: serum anti-measles antibody ratio. The male to female ratio in the present study was 4.4:1. The mean age at onset of SSPE was 13.3 years, showing an increase in mean age at onset of SSPE. Clinical and other demographic details, available from 72 in-patients, are discussed in this report. Of these, a history of measles could be elicited in 34 cases. Mean latent period between measles infection and onset of SSPE was 7.8 years. Six patients gave a history of measles vaccination. A sizable percentage (15.5 %) of the patients was > or = 18 years old and considered to have adult onset SSPE. The incidence of SSPE continues to be high and this report highlights the need for further strengthening routine measles immunization coverage.

Abstract
Conventional and crossed immunoelectrophoresis were used to characterize oligoclonal gamma-globulin bands of the cerebrospinal fluid (CSF) of patients with multiple sclerosis (MS) or subacute sclerosing panencephalitis (SSPE) or other infections of the central nervous system. Most gamma-globulin bands were identified as IgG, but some bands were identified as kappa or lambda, or both, free light chains, Bands of IgG showed various degrees of light-chain diversity, and individual bands appeared in many instances to be derived from more than one clone of cells. Sequential changes of the oligoclonal IgG were observed in SSPE but not in MS. Oligoclonal IgG was detected in sera from most patients with SSPE and some patients with MS.

Abstract
OBJECTIVE To demonstrate the specificity of expanded CD138(+) plasma cell clones recovered from the CSF of a patient with subacute sclerosing panencephalitis (SSPE) for measles virus (MV). METHODS IgG variable region sequences of single-antibody-secreting CD138(+) cells sorted from SSPE CSF were amplified by single-cell PCR and analyzed. Human IgG1 recombinant antibodies (rAbs) were produced from four expanded CD138(+) clones and assayed for immunoreactivity against MV proteins. RESULTS Clonal expansion was a prominent feature of the SSPE plasma cell repertoire, and each of the four rAbs assayed was specific for either the MV fusion or the MV nucleocapsid protein. CONCLUSIONS Expanded plasma cell clones in the CSF of patients with subacute sclerosing panencephalitis produce disease-relevant antibodies. Recombinant antibodies derived from CSF B cells could provide a tool to identify target antigens in idiopathic inflammatory disorders.

Abstract
The detection of intrathecal antibody synthesis by qualitative methods or the Antibody-Index (AI) is a relevant tool for diagnosis of inflammatory neurological diseases. An increased AI can be observed for a causative antigen as well as part of a polyspecific immune response. The quantitation of the intrathecal antibody fraction in cerebrospinal fluid (CSF), F(S), helps to discriminate both cases. In contrast to AI, F(S) needs an absolute antibody concentration detected in the ELISA in mg/L. The intrathecally synthesized, "local" antibody concentration in CSF (AB(Loc)) is expressed as the specific fraction of the intrathecally synthesized total IgG (IgG(Loc)) in CSF with F(S)=AB(Loc)/IgG(Loc) x 100 in %. F(S) for HSV or measles has about 20- to 60-fold higher values in virus-caused antibody synthesis in acute herpes simplex encephalitis (mean HSV-F(S)=8.9%) or subacute sclerosing panencephalitis (mean measles-F(S)=18.8%) compared to the polyspecific immune response against these antigens e.g., in multiple sclerosis (0.14% or 0.52%, correspondingly). F(S) helps also to avoid misinterpretations of an increasing AI in cases of therapy control, and allows direct comparison of relative antibody concentrations (R(S)) in blood and intrathecally synthesized fractions in CSF (F(S)): In multiple sclerosis patients F(S):R(S) has a mean ratio of about 3 for the measles, rubella and VZV antibodies. Together with the large variability we find by ranking that about two third of MS patients have no direct correlation of the relative concentrations in serum and intrathecal synthesis. So this concept gains increasingly relevance for analysis of the polyspecific immune response in brain.

Abstract
Infectious and inflammatory diseases of the CNS are often characterized by a robust B-cell response that manifests as increased intrathecal immunoglobulin G (IgG) synthesis and the presence of oligoclonal bands. We previously used laser capture microdissection and single-cell PCR to analyze the IgG variable regions of plasma cells from the brain of a patient with subacute sclerosing panencephalitis (SSPE). Five of eight human IgG1 recombinant antibodies (rAbs) derived from SSPE brain plasma cell clones recognized the measles virus (MV) nucleocapsid protein, confirming that the antibody response in SSPE targets primarily the agent causing disease. In this study, as part of our work on antigen identification, we used four rAbs to probe a random phage-displayed peptide library to determine if epitopes within the MV nucleocapsid protein could be identified with SSPE brain rAbs. All four of the SSPE rAbs enriched phage-displayed peptide sequences that reacted specifically to their panning rAb by enzyme-linked immunosorbent assay. BLASTP searches of the NCBI protein database revealed clear homologies in three peptides and different amino acid stretches within the 65 C-terminal amino acids of the MV nucleocapsid protein. The specificities of SSPE rAbs to these regions of the MV nucleocapsid protein were confirmed by binding to synthetic peptides or to short cDNA expression products. These results indicate the feasibility of using peptide screening for antigen discovery in central nervous system inflammatory diseases of unknown etiology, such as multiple sclerosis, neurosarcoidosis, or Behcet's syndrome.

Abstract
Increased immunoglobulin G (IgG) and intrathecally produced oligoclonal bands (OGBs) are characteristic of a limited number of inflammatory central nervous system (CNS) diseases and are often directed against the cause of disease. In subacute sclerosing panencephalitis (SSPE), the cause of disease and the target of the oligoclonal response is measles virus (MV). The authors previously showed that clonally expanded populations of CD38+ plasma cells in SSPE brain, the likely source of OGBs, are directed against MV. In characterizing the breadth of the plasma cell reactivities, the authors found that a large proportion of the less abundant plasma cells are also directed against MV. The intrathecal response may be useful in determining the causes of other inflammatory CNS diseases, such as multiple sclerosis, Behcet's disease, and neurosarcoidosis.

Abstract
Subacute sclerosing panencephalitis (SSPE) is a progressive, fatal neurological disorder of childhood and early adolescence. It is caused by a persistent measles virus infection of the brain without any available treatment to date. The physiopathology of the disease is largely unknown. Considering the potential role of humoral immunity in the pathogenesis of SSPE, one patient was given compassionate anti-CD20 antibodies. However, disease progression under treatment led to reconsider B cell involvement in this pathology. Nevertheless, we observed that carbamazepine was useful in improving life quality in our patient, and should be considered as a first-line drug. To date, measles vaccination remains the only solution to SSPE.

Abstract
Measles virus (MV) nucleocapsids are present abundantly in brain cells of patients with subacute sclerosing panencephalitis (SSPE). This invariably lethal brain disease develops years after acute measles as result of a persistent MV infection. Various rodent models for MV infection of the central nervous system (CNS) have been described in the past, in which the detection of viral antigens is based on histological staining procedures of paraffin embedded brains. Here, the usage of a recombinant MV (MV-EGFP-CAMH) expressing the haemagglutinin (H) of the rodent-adapted MV-strain CAM/RB and the enhanced green fluorescent protein (EGFP) is described. In newborn rodents the virus infects neurons and causes an acute lethal encephalitis. From 2 weeks on, when the immune system of the genetically unmodified animal is maturating, intracerebral (i.c.) infection is overcome subclinically, however, a focal persistent infection in groups of neurons remains. The complete brain can be analysed in 50 or 100 microm slices, and infected autofluorescent cells are readily detected. Seven and 28 days post-infection (p.i.) 86 and 81% of mice are infected, respectively, and virus persists for more than 50 days p.i. Intraperitoneal immunization with MV 1 week before infection, but not after infection, protects and prevents persistence. The high percentage of persistence demonstrates that this is a reliable and useful model of a persistent CNS infection in fully immunocompetent mice, which allows the investigation of determinants of the immune system.

Abstract
BACKGROUND Subacute sclerosing panencephalitis (SSPE) usually has a progressive stereotypic downhill course and results in premature death. Long-term stabilization or remission is exceptional. OBJECTIVE To analyze the profile of patients with a relatively 'benign' course who survive beyond 3 years. DESIGN Descriptive analysis of 19 (16 male, 3 females)/307 (6.2%) patients with benign course who were evaluated at NIMHANS between January 1995 and December 2004. Their diagnosis was based on characteristic myoclonic jerks, elevated antibody titers against measles virus in CSF and periodic complexes in EEG. RESULTS The mean age at onset of symptoms was 11.7+/-3.9 years and mean duration of follow-up from first symptom was 5.9+/-3.1 years (3-13.8 years). Their initial symptoms were seizures (7), myoclonus (6), visual disturbances (4), behavioral changes (1) and cognitive impairment (1). These patients had varied clinical course: stabilization in different stages for 6 months to 5 years (13), remissions for 6 months to 9 years and reversal of staging with functional recovery from being bed bound to ambulant (8). Their diagnosis was often delayed. Small sample size did not permit to analyze the influence of possible disease modifying agents used in 10 patients (isoprenosine-3, amantidine-4, oral steroids-4, methylprednisolone-1, intravenous immunoglobulin-1). CONCLUSIONS Our observations suggest that SSPE may have a highly variable clinical course and warrants cautious approach for counseling at initial evaluation and while interpreting beneficial effect of disease modifying agent(s). There is a need to explore prognostic marker(s).

Abstract
BACKGROUND Subacute sclerosing panencephalitis (SSPE) is a rare progressive inflammatory disease characterized by the persistent infection of the brain by the measles virus. However, the immunological pathophysiology of SSPE is still unclear. METHODS We measured the concentrations of interferon-gamma (IFN-gamma), tumor necrosis factor-alpha (TNF-alpha), interleukin-2 (IL-2), IL-4, IL-6, IL-10, and soluble TNF receptor 1 (sTNFR1) in the serum and cerebrospinal fluid (CSF) of 23 patients with SSPE in Papua New Guinea (PNG), a country with a high incidence of SSPE, and Japanese controls by cytometric bead array or ELISA. RESULTS The serum IL-6 and IL-10 levels of SSPE patients were significantly higher than those of controls (p=0.0075, and p=0.0019, respectively). The serum IL-6 and IL-10 levels of SSPE patients with fever were significantly higher than those without fever (p=0.0107, and p=0.0006, respectively). The CSF IL-6 levels of SSPE patients were significantly higher than those of controls (p=0.0218). The CSF IL-6 levels of SSPE patients with myoclonic jerks were significantly higher than those without myoclonic jerks (p=0.0189). There were no differences in serum IFN-gamma, TNF-alpha, IL-2, IL-4, and sTNFR1, or CSF IFN-gamma, TNF-alpha, IL-2, IL-4, IL-10, and sTNFR1 levels between the affected patients and controls. CONCLUSION Our present study suggests that serum IL-6 and IL-10 levels are related to fever, and the CSF IL-6 level, myoclonic jerks, in SSPE patients in PNG.

Abstract
BACKGROUND AND AIMS Autoimmune pancreatitis is usually associated with elevated serum IgG4 concentrations, and sometimes with sclerosing cholangitis and Sjögren's syndrome. This study aimed to elucidate the proposed entity of IgG4-related sclerosing disease. METHODS Subjects were patients with autoimmune pancreatitis (n = 26), sclerosing sialadenitis (n = 5), chronic alcoholic pancreatitis (n = 20), sialolithiasis (n = 34), Sjögren's syndrome (n = 50), and primary sclerosing cholangitis (n = 3). Sections of various organs and tissues of these patients were examined immunohistochemically using antibodies to CD4-T, CD8-T, and CD20-B cell subsets and IgG4, and serum IgG4 concentrations were measured. RESULTS Patients with autoimmune pancreatitis were associated with sclerosing cholangitis (n = 23), sclerosing sialadenitis (n = 2), retroperitoneal fibrosis (n = 2), and abdominal (n = 5) and cervical (n = 4) lymphadenopathy. They demonstrated infiltrations of more abundant IgG4-positive plasma cells in the pancreas, peripancreatic retroperitoneal tissues, extrahepatic bile duct, gallbladder, stomach, minor salivary gland, and abdominal lymph nodes compared with those of other diseases (p < 0.01). Such infiltrations were also observed in the minor salivary gland and submandibular gland of patients with sclerosing sialadenitis (p < 0.01). Serum IgG4 concentrations were significantly elevated in patients with autoimmune pancreatitis and sclerosing sialadenitis (p < 0.01). CONCLUSION We propose a new clinicopathological entity of IgG4-related sclerosing disease incorporating sclerosing pancreatitis, cholangitis, sialadenitis and retroperitoneal fibrosis with lymphadenopathy.

Abstract
Subacute sclerosing panencephalitis (SSPE) is a progressive fatal neurodegenerative disease associated with persistent infection of the central nervous system (CNS) by measles virus (MV), biased hypermutations of the viral genome affecting primarily the matrix (M) gene with the conversion of U to C and A to G bases, high titers of antibodies to MV, and infiltration of B cells and T cells into the CNS. Neither the precipitating event nor biology underlying the MV infection is understood, nor is their any satisfactory treatment. We report the creation of a transgenic mouse model that mimics the cardinal features of SSPE. This was achieved by initially infecting mice expressing the MV receptor with lymphocytic choriomeningitis virus Cl 13, a virus that transiently suppressed their immune system. Infection by MV 10 days later resulted in persistent MV infection of neurons. Analysis of brains from infected mice showed the biased U to C hypermutations in the MV M gene and T and B lymphocyte infiltration. These sera contained high titers of antibodies to MV. Thus, a small animal model is now available to both molecularly probe the pathogenesis of SSPE and to test a variety of therapies to treat the disease.

Abstract
To investigate T cell responses in subacute sclerosing panencephalitis (SSPE), we analyzed proliferation and cytokine secretion of cells from 35 patients and 42 healthy controls (HC) in response to central nervous system (CNS) antigens. The proliferation in response to myelin basic protein (MBP), myelin oligodendrocyte-glycoprotein (MOG) and alphaB-crystallin did not differ between groups. There was a trend towards a decrease in IL-12 production in response to MBP and in vitro IL-12 secretion of SSPE patients to measles virus vaccine (MVV) was lower than controls. Proliferation, as well as IFN-gamma, IL-12 and IL-10 production in response to purified protein derivate (PPD) was impaired in SSPE patients. The results did not demonstrate any by-stander cellular response against myelin antigens, implicating that CNS is not a predominant target of an autoimmune response in SSPE. The recall responses were lower in SSPE as reported in measles before.

Abstract
The incidence of subacute sclerosing panencephalitis may be rising. This report describes three patients identified in New York City with atypical features including age of onset, prolonged prodrome, and lack of specific electroencephalographic changes. The diagnosis was confirmed with the identification of measles antibodies in the cerebrospinal fluid. Awareness of the possibility that the clinical presentation of subacute sclerosing panencephalitis may be changing may increase its timely diagnosis.

Abstract
Mechanisms causing persistence and reactivation of measles virus in subacute sclerosing panencephalitis (SSPE) are unknown. Borna disease virus (BDV) frequently causes latent or persistent infection in the nervous system. We investigated a possible association of these viruses in SSPE. Although BDV seropositivity was similar in SSPE and control groups, SSPE patients with high antibodies to BDV had earlier and more rapid disease. The findings suggest that BDV might be involved in the course, but not in the etiopathogenesis, of SSPE.

Abstract
Immunologic studies in relation to clinical status might help to understand the pathogenesis of subacute sclerosing panencephalitis (SSPE) and the effect of treatment. We measured lymphocyte subsets and intracellular TNFalpha and interleukin-4 levels in peripheral blood in SSPE patients. Patients had elevated percentages of CD8+ cells compared to age-matched control children. Rapidly progressive course was associated with increased CD4+ cells. Treatment with interferons and inosiplex altered the percentage of CD3+, CD4+ and CD19+ cells. TNFalpha and interleukin-4 levels had no correlation with course or treatment. The proportions of lymphocyte subsets appear to have a role in the evolution or manifestations of SSPE, if not in the pathogenesis.

Abstract
Increased IgG and oligoclonal bands are found in cerebrospinal fluid of humans with chronic infectious CNS disease. Studies have shown that these oligoclonal bands are antibodies directed against the agent that causes disease. Laser-capture microdissection was used to isolate individual CD38+ plasma cells from the brain of a patient with subacute sclerosing panencephalitis, and single-cell RT-PCR was used to analyze individual IgG heavy and light chains expressed by each cell. Based on overrepresented IgG sequences, we constructed functional recombinant antibodies (recombinant IgGs) and determined their specificities. Five of eight recombinant IgGs recognized measles virus, the cause of subacute sclerosing panencephalitis. These results demonstrate that overrepresented IgG sequences in postmortem brains can be used to produce functional recombinant antibodies that recognize their target antigens. This strategy can be used to identify disease-relevant antigens in CNS inflammatory diseases of unknown etiology.

Abstract
Subacute sclerosing panencephalitis (SSPE) is a neurodegenerative disorder due to persistent measles virus infection, with high level of measles-specific antibodies in cerebrospinal fluid (CSF). To analyze whether such response arises from a TH2-biased response, the authors determined TH1 (interferon [IFN]-gamma) and TH2 (interleukin [IL]-4 and IL-10) cytokines in CSF, taken at diagnosis, of eight SSPE patients (median age, 57.5 month, range 42 to 76 months). All patients presented IL-10 (median 29.3 pg/ml, range 4.3 to 162 pg/ml), but not IL-4 (<10 pg/ml); only one case showed IFN-gamma (162 pg/ml). These results are consistent with a TH2 bias or with a local, anti-inflammatory or neuroprotective mechanism involving IL-10.

Abstract
Subacute sclerosing panencephalitis is a form of chronic persistent measles encephalitis in childhood which rarely manifests after wild virus infection. One previous case of familial subacute sclerosing panencephalitis in two siblings and a number of reports of subacute sclerosing panencephalitis in one member of monozygous twins have been reported in the literature. This report describes a second sibling set who both contracted subacute sclerosing panencephalitis after concurrent sporadic measles infection. Two nonimmunized brothers developed neuropsychological decline and progressive myoclonic and complex partial seizures after earlier measles infection. Stereotyped periodic 5- to 8-second complexes in the electroencephalogram suggested the diagnosis of subacute sclerosing panencephalitis, subsequently confirmed by intrathecal and serum measles-specific immunoglobulin G synthesis and the presence of rubeola nucleocapsid protein and ribonucleic acid in the biopsied brain. The viral genome has not been further subtyped in either patient at this point. Although a rare event, subacute sclerosing panencephalitis cases involving familial and singular monozygous twins may shed light on a variety of host susceptibility factors and specific viral genotype features predisposing to this disease.

Abstract
The authors used a liquid-phase radiobinding assay to measure serum anti-myelin oligodendrocyte protein (MOG) immunoglobulin (Ig) G in 87 patients with multiple sclerosis (MS), in 12 patients with encephalomyelitis, and in 47 healthy subjects. Anti-MOG IgM was determined in samples obtained at onset from 40 of 87 patients with MS and in control subjects. The frequency of positive samples with low titers of anti-MOG IgG (< or =5.7%) and IgM (< or =8.3%) was similar in all the groups and subgroups. Binding competition experiments showed that these antibodies had low affinity. Anti-MOG antibodies are not disease specific.

Abstract
Limited analyses of cerebrospinal fluid from patients with central nervous system infections have shown that the oligoclonal IgG is antibody directed against the agent that causes disease. Using a new method involving binding of IgG to beads coated with lysates prepared from candidate infectious antigens, we showed that the oligoclonal IgG in cerebrospinal fluid of a patient with chronic varicella zoster virus vasculopathy is directed against the causative virus. This approach holds promise in identifying and purifying the relevant oligoclonal IgGs in inflammatory central nervous system diseases of unknown cause.

Abstract
The aim of this prospective study was to clarify the ramifications of neuroimaging patterns associated with neurologic outcomes of acute measles encephalitis. Twelve patients with neurologic complications stemming from a measles outbreak were diagnosed based on characteristic clinical features, the presence of measles-specific antibodies, and abnormal cerebrospinal fluid findings. Neuroimaging studies were then performed during the acute phase of the disease. Our subject group consisted of four males and eight females (mean age: 9.9 years). Main neurologic findings were loss of consciousness, seizures, and paralysis. Serum tests for measles-specific Ig G and M antibodies were positive in eleven patients. Neuroimages of the group revealed the following three abnormalities: (1). demyelination of white matter with hypoperfusion on interictal single-photon-emission computed tomography, (2). high signal intensity of gray matter with hypoperfusion on interictal single-photon-emission computed tomography, and (3). normal MRI with hypoperfusion on single-photon-emission computed tomography. We identified a new pattern of acute measles encephalitis that involved cortical and/or deep gray matter, and this finding suggests a variant in the pathogenesis of acute measles encephalitis. Patients that demonstrated a gray matter abnormality had a higher rate of complications and required longer periods of hospitalization.

Abstract
Eighty-three children presented at Goroka Base Hospital in the Eastern Highlands Province (EHP) of Papua New Guinea over a period of 3 years and 9 months between February 1997 and November 2000 were confirmed to have subacute sclerosing panencephalitis (SSPE). Confirmation of the diagnosis was based on the demonstration of high titres of measles antibodies in the cerebrospinal fluid and/or serum in association with clinical features supportive of SSPE, including characteristic electroencephalographic changes and amplification of measles virus genome by reverse transcriptase polymerase chain reaction in some cases. The mean cerebrospinal fluid and serum enzyme immunoassay antibody levels among the SSPE patients were 38 250 and 860 580, respectively. The mean age of onset of SSPE was 7.9 +/- 2.6 years and ranged between 2 and 14 years. The overall male to female ratio was 1.2:1 and 1.4:1 for EHP.

Abstract
Subacute sclerosing panencephalitis (SSPE) is a slowly progressive and highly lethal disease of the central nervous system. Although the primary cause of SSPE is believed to be persistent infection of neuron and glial cells by a measles virus, the precise mechanism of the progression of this disease has not yet been elucidated. CD9, a member of the tetraspanin family, is expressed in myelin and other nervous tissues. This study detected significant amounts of anti-CD9 antibodies in the cerebrospinal fluid (CSF) of all patients with SSPE included in the study. Anti-CD9 antibodies were also detected in the CSF of some patients with other neurologic disorders, but those patients had lower levels of anti-CD9 antibodies than did the patients with SSPE. The level of anti-CD9 antibodies was elevated and reached a peak that coincided with the appearance of brain atrophy. These findings shed light on a new aspect of the causes and progression of SSPE.

Abstract
OBJECTIVES The pathogenesis of subacute sclerosing panencephalitis (SSPE), and particularly, the cause of measles virus (MV) reactivation following a latent period after primary measles infection is unknown. The hypothesis of other viruses contributing to the pathogenesis of SSPE by affecting the in vivo state of MV was investigated. METHODS We examined the cerebrospinal fluid of SSPE patients (n=43) for DNA or RNA and antibodies against HSV type 1 and 2, EBV, CMV, VZV, Hepatitis B, Hepatitis C, JC virus, human herpesvirus (HHV)-6, HHV-7, HHV-8, HTLV-1, and HTLV-2. We compared the findings with those of patients with other neurological disorders (n=39). RESULTS CMV DNA and HSV type 1 IgG were found more frequently in SSPE patients. Other positive results were at similar incidence in SSPE and control groups. The clinical features of SSPE cases with and without positive viral tests did not differ from each other. CONCLUSION These data do not support a specific role for these agents in SSPE, but imply that the passage of some viruses to the CNS and local antibody synthesis may be facilitated by inflammation. The persistence or reactivation of MV in SSPE may be related to other factors pertaining to the host or environment.

Abstract
This paper presents ultrastructural changes in neuronal and glial cells with special reference to intranuclear inclusion bodies in subacute sclerosing panencephalitis (SSPE) with different duration (from several weeks to seven years). Brain autopsy at ultrastructural level revealed the nucleocapsids of paramyxovirus in neuronal and oligodendroglial nuclei in 4 of 6 SSPE cases under study. Nucleocapsids of measles virus were present in two cases of disease lasting several weeks and in two cases with disease duration of two years, while abundant nuclear bodies and granulofilamentous inclusions in astrocytic nuclei were found in all cases. Occasionally, both granulofilamentous inclusions and complex nuclear bodies occurred in the same astrocytic nucleus. Only in the case lasting seven years they were not observed. It is likely that there is a structural and morphological relationship between these two types of inclusions present in astrocytic nuclei. Nuclear bodies and granulofilamentous inclusions were common and independent of the presence or absence of virus nucleocapsids. In the case of SSPE with a seven-year duration but without viral nucleocapsids in neuronal and oligodendroglial nuclei, neuronal tangles were observed.

Abstract
We describe the first case in which de novo production of multiple IgG antinuclear antibodies (ANA) occurred in a female neonate of an ANA negative mother. The infant presented at 4 weeks of age with hemorrhagic panencephalitis, diffuse intraparenchymal hemorrhages, and straight sinus thrombosis. She had been vaccinated against hepatitis B at birth. No other cause was found and maternal prenatal care was unremarkable. The infant's screening ANA test by ELISA was positive at 6 weeks with specificity for ssDNA, Sm, and nRNP/Sm. At 8 weeks antibodies to dsDNA and centromere were detected as well. By 8 months, she still had slightly elevated anti-dsDNA, Sm, and nRNP/Sm antibodies. The ANA test by immunofluorescence was abnormal at 8 weeks through 13 weeks with centromere and then homogeneous pattern. Based on similarities with other reported cases, we speculate that hepatitis B vaccination may have been involved in the development of antinuclear antibodies.

Abstract
The presence of increased IgG in the brains of humans with infectious and inflammatory CNS diseases of unknown etiology such as multiple sclerosis may be a clue to the cause of disease. For example, the intrathecally synthesized oligoclonal bands in diseases such as subacute sclerosing panencephalitis (SSPE) or cryptococcal meningitis have been shown to represent Ab directed against the causative agents, measles virus (MV), or Cryptococcus neoformans, respectively. Using SSPE as a model system, we developed a strategy to identify the antigenic targets of the intrathecal disease-relevant IgG in chronic human inflammatory and demyelinating diseases of the CNS. Libraries of cDNA Ags were displayed on the surface of T7Select bacteriophage and biopanned on IgG extracted from the brain of an SSPE patient, or on a monospecific recombinant Fab identified from SSPE brain. After three or six rounds of biopanning on either Ab, positive phage-displayed Ags reacting with IgG were enriched to 35-77% of all panned clones. Sequence analysis of the positive clones identified fragments of the nucleocapsid protein of MV, the cause of SSPE. The sensitivity of the system was determined by diluting the positive clones from this SSPE phage-displayed library at a ratio of 10(-6) into another phage-displayed library that did not contain any detectable MV Ags; after six rounds of panning, the positive clones comprised 34% of all phage and were also shown to be MV nucleocapsid specific. This strategy will be useful to identify potentially rare Ags in diseases of unknown cause.

Abstract
Although CNS complications occurring early and late after acute measles are a serious problem and often fatal, the transient immunosuppression lasting for several weeks after the rash is the major cause of measles-related morbidity and mortality worldwide. This review is focused on the interactions of measles virus (MV) with cellular receptors on neural and lymphoid cells which are important elements in viral pathogenesis. First, the cognate MV receptors, CD46 and CD150, are important components of viral tropism by mediating binding and entry. Second, however, additional unknown cellular surface molecules may (independently of viral uptake) after interaction with the MV glycoprotein complex act as signaling molecules and thereby modulate cellular survival, proliferation, and specific functions.

Abstract
Subacute sclerosing panencephalitis is a rare progressive inflammatory disease of the central nervous system caused by a persistent aberrant measles virus infection. Cytokines are polypeptides that regulate immune responses and inflammatory reactions. Interleukin-1beta has been implicated as a central mediator of tissue damage and destruction in a number of central nervous system diseases. Interleukin-1 receptor antagonist could function as an important anti-inflammatory cytokine. We studied interleukin-1beta and interleukin-1 receptor antagonist levels in the cerebrospinal fluids of patients with subacute sclerosing panencephalitis and evaluated the effects of different treatment protocols on these cytokines. Interleukin-1beta and interleukin-1 receptor antagonist levels were measured in 15 patients who had a recent diagnosis of subacute sclerosing panencephalitis (group 1), 6 patients who had been treated with isoprinosine (group 2), 5 patients with intraventricular interferon-alpha (group 3), and 6 patients with interferon-beta (group 4). The results were compared within the groups and also with the results of 10 patients with other neurologic disease (group 5). The interleukin-1beta concentrations in cerebrospinal fluid and sera were all below the detection limits (3.9 pg/mL). Interleukin-1 receptor antagonist levels were not statistically different, except for the group treated with intraventricular interferon-alpha. Interleukin-1 receptor antagonist levels were 170 +/- 52, 175 +/- 58, 1605 +/- 518, 77.5 +/- 24, and 108 +/- 18 pg/mL in groups 1 to 5, respectively. Interleukin-1 receptor antagonist levels and cerebrospinal fluid serum ratios were significantly increased during interferon-alpha treatment. In conclusion, interleukin-1 and interleukin-1 receptor antagonist levels were not elevated in the patients with subacute sclerosing panencephalitis. The only treatment protocol that affects interleukin-1 receptor antagonist levels in cerebrospinal fluid was intraventricular interferon-alpha. Further studies on higher numbers of patients may better document the immunologic status of patients with subacute sclerosing panencephalitis and the effects of different treatment modes.

Abstract
Subacute sclerosing panencephalitis (SSPE) remains a problem in areas of the world where measles virus is prevalent because of a lack of commitment to universal vaccination. We recently studied 89 cases compatible with a clinical diagnosis of SSPE and tested for antibody in serum or cerebrospinal fluid for measles virus. Eleven cases were confirmed to be SSPE on the basis of strongly supportive laboratory data.

Abstract
We present the unique case of a 2-year-old girl with congenital athyreosis who acquired primary measles virus infection at the age of 18 months, coincidentally with an Epstein-Barr virus infection. First neurologic symptoms of subacute sclerosing panencephalitis appeared 5 months later, and the girl died within 6 months after a rapid progressive illness. Factors possibly predisposing to this extraordinary disease course-primary measles virus infection at an early age and lack of evidence for immunodeficiency-are discussed.

Abstract
The clinical, virological and immunocytochemical features of three children who recovered from acute herpes simplex encephalitis (HSE) before the age of 2 years, and who developed secondary severe focal epilepsy after a symptom-free period, leading to neurosurgery 3-10 years later are described. In one child, relapse of HSE occurred immediately after surgery. In all three patients, brain sample biopsies showed abundant CD3-positive T lymphocytes with a majority of CD8 cells, and abundant activated macrophage-microglial cells, a pattern similar to that found in acute HSE. Herpes simplex virus DNA was retrieved from the tissue biopsy in one case. The long-term persistent cerebral inflammatory process observed after HSE differed from that observed in another chronic viral disease, subacute sclerosing panencephalitis. This inflammatory reaction may be a result either of low-grade viral expression or self-induced immune activation. The role of inflammation in triggering epilepsy remains hypothetical. Solving these issues should have major therapeutic implications. Herpes simplex virus DNA latency in brain may be the source of replicative HSE relapse.

Abstract
Live measles virus-specific T helper 1/T helper 2-cytokine productions by peripheral blood mononuclear cells in response to live measles, mumps or varicella virus were measured in 15 patients with subacute sclerosing panencephalitis and 15 controls by enzyme-linked immunosorbent assays. Most patients with subacute sclerosing panencephalitis had a defect in measles virus-specific production of interferon-gamma, one of the T helper 1 type cytokines, despite persistent presence of measles virus, with preserved interleukin-10 (T helper 2 type cytokine) synthesis. Patients with subacute sclerosing panencephalitis were divided into two groups: responders (group A) with significant interferon-gamma production (>20 pg/mL) in response to live measles virus and non-responders (group B) with a little or no interferon-gamma production. Comparison of the clinical courses between groups A and B revealed that all the patients of group A retained receptive function for a long time, while most patients of group B lost the function rapidly (P<0.01). An inverse correlation between interferon-gamma production by peripheral blood mononuclear cells and disease progression suggested that interferon-gamma plays an antiviral role in subacute sclerosing panencephalitis.

Abstract
OBJECTIVE To better understand B-cell activation in MS by analyzing the immunoglobulin (Ig)G heavy chain variable region (VH) repertoire found in MS brains and comparing it with brain VH sequences in individuals with subacute sclerosing panencephalitis (SSPE)--a chronic encephalitis produced by measles virus (MV)-and characterized by an antigen-driven oligoclonal IgG response to MV antigens. BACKGROUND The specificity of oligoclonal IgG in MS CSF and plaques, and their relevance to the pathogenesis of MS is unknown. METHODS Nested PCR was used to amplify and sequence the rearranged IgG heavy-chain VH repertoire in plaques of three acute MS brains and in three SSPE brains. A representative population of VH sequences from each tissue was aligned to the known 51 functional VH germline segments. From this the authors determined the closest VH family germline segment, and the degree and location of somatic mutations for each unique IgG. RESULTS As expected for an antigen-driven response against MV antigens, most VH sequences from the SSPE brains were mutated extensively compared with their closest germline segments. Furthermore, SSPE VH sequences accumulated replacement mutations preferentially in the complementary-determining regions (CDRs) relative to framework regions-features normally observed during antigen-driven selection. A comparison of VH family and germline usage also demonstrated that each SSPE brain had its own unique IgG response. When the authors compared the VH response in MS plaques with SSPE, MS VH sequences were also mutated extensively, displayed a preferential accumulation of replacement mutations in CDRs, and were unique in each MS brain. CONCLUSION The presence of an antigen-driven response in MS, rather than a nonconventional mechanism of B-cell activation, warrants additional analysis of the specificity of IgG in MS brain and CSF.

Abstract
In central nervous system (CNS) infectious and inflammatory diseases of known cause, oligoclonal bands represent antibody directed against the causative agent. To determine whether disease-relevant antibodies can be cloned from diseased brain, we prepared an antibody phage display library from the brain of a human with subacute sclerosing panencephalitis (SSPE), a chronic encephalitis caused by measles virus, and selected the library against SSPE brain sections. Antibodies that were retrieved reacted strongly with measles virus cell extracts by enzyme-linked immunosorbent assay and were specific for the measles virus nucleocapsid protein. These antibodies immunostained cells in different SSPE brains but not in control brain. Our data provide the first demonstration that diseased brain can be used to select in situ for antibodies directed against the causative agent of disease and point to the potential usefulness of this approach in identifying relevant antibodies in chronic CNS or systemic inflammatory diseases of unknown cause.

The presence of increased IgG in the brains of humans with infectious and inflammatory CNS diseases of unknown etiology such as multiple sclerosis may be a clue to the cause of disease. For example, the intrathecally synthesized oligoclonal bands (OGBs) in diseases such as subacute sclerosing panencephalitis (SSPE) or cryptococcal meningitis have been shown to represent Ab directed against the causative agents, measles virus (MV) or Cryptococcus neoformans, respectively. Using SSPE as a model system, we have developed a PCR-based strategy to analyze the repertoire of IgG V region sequences expressed in SSPE brain. We observed abnormal expression of germline V segments, overrepresentation of particular sequences that correspond to the oligoclonal bands, and substantial somatic mutation of most clones from the germline, which, taken together, constitute features of Ag-driven selection in the IgG response. Using the most abundant or most highly mutated gamma H chain and kappa or lambda L chain sequences in various combinations, we constructed functional Abs in IgG mammalian expression vectors. Three Abs specifically stained MV-infected cells. One Ab also stained cells transfected with the MV nucleoprotein, and a second Ab stained cells transfected with the MV-fusion protein. This technique demonstrates that functional Abs produced from putative disease-relevant IgG sequences can be used to recognize their corresponding Ags.

Abstract
A defective cell-mediated immunity and inflammatory cytokines are suggested in the pathogenesis of subacute sclerosing panencephalitis. In this study we analyzed lymphocyte subsets in peripheral blood and concentrations of interleukin-1alpha (IL-1alpha), interleukin-2 (IL-2alpha), tumor necrosis factor-alpha (TNF-alpha), and platelet activating factor in plasma and cerebrospinal fluid before and after immunomodulatory therapy (interferon-alpha plus isoprinosine) in three patients with subacute sclerosing panencephalitis. Increased percentage of CD8+cells (T-suppressor/cytotoxic cell) and CD16+CD56+cells (NK cell) and reduced percentage of CD3+/HLA-DR+ (active T-cell) and CD3+ (total T-cell) cells were found before therapy. After immunomodulatory therapy, CD3+/HLA-DR+ (active T-cell) cells were markedly increased and there was a slight increase in the percentages of all lymphocyte subsets in the patients. The concentrations of platelet activating factor in plasma and cerebrospinal fluid were higher than the mean value in controls. Cerebrospinal fluid and plasma TNF-alpha and IL-2 levels were nondetectable in two patients who had a stationary course of disease and were markedly elevated in patient 3, who displayed a rapidly progressive course.

Abstract
Two sibling viruses of the subacute sclerosing panencephalitis (SSPE) virus Osaka-2 strain were isolated from a small biopsy specimen of the brain of an SSPE patient just before intraventricular interferon treatment by cocultivation with two different cell lines, Vero cells or B95a cells (Ogura et al, 1997). Both the virus-infected cells were found to be indistinguishable from each other in defective production of cell-free virus and in defective expression of the matrix (M) protein. The sequence analysis of the M genes predicted that they were translatable due to a lack of alteration of the translational start and stop codons for the proteins. A different pattern of the M monocistronic transcripts, however, was observed in a Northern blot analysis of the infected cells. This different pattern was confirmed further by a primer extension analysis. The undetectable expressions of the M proteins in the sibling virus-infected cells are most probably different in their molecular mechanisms. All these results indicate the possibility that the two different, replicable variants existed at Jabbour stage III of the disease's progression in a very small portion of the brain, where no lesion had yet been recognized by a magnetic resonance imaging.
