Objective: To determine IgG antibody levels of measles, rubella, mumps in healthy population in Shanghai from 2010 to 2020 and analyze the trend of antibody changes in different age groups. Methods: 10 828 healthy people without measles, rubella and mumps in Shanghai were included in the study from 2010 to 2020. Serum samples were collected from 12 age groups, and the serum IgG antibody of measles, rubella and mumps were detected by ELISA. The difference of antibody positive rates and antibody levels were analyzed. Results: The median age M (Q₁, Q₃) of 10 828 objects were 8 years old (9 months old, 20 years old). Males accounted for 48.34% (5 234/10 828) and females accounted for 50.92% (5 514/10 828). Unknown gender information accounted for 0.74% (80/10 828), and 27.03% (2 927/10 828) of participants had unknown MMR immunization history. The total positive rates of measles, rubella and mumps IgG antibody were 76.78%, 64.46% and 64.29% and their GMCs were 541.45 mIU/ml, 31.76 IU/ml and 133.73 U/ml respectively. There were significant differences in serum IgG antibody GMC of measles, rubella and mumps in each year (F_measles=180.74, P<0.001; F_rubella=189.95, P<0.001; F_mumps=122.40, P<0.001). The positive rate of measles antibody was higher than that of rubella and mumps, and the difference was statistically significant (χ²=518.09, P<0.001). Conclusion: The level of measles IgG antibody in healthy people in Shanghai is higher, while the level of rubella and mumps IgG antibody is slightly lower.

Background. Subacute sclerosing panencephalitis (SSPE) is a fatal neurodegenerative disease caused by prolonged persistent infection of the central nervous system with a measles virus mutant. Though various treatment modalities have been tried, there is no effective treatment to completely cure SSPE and new therapeutic strategies are needed.

Objective. This is a prospective uncontrolled observational open label trial to describe the short-term outcomes and safety of intraventricular ribavirin in combination with oral isoprinosine in Filipino SSPE patients.

Methods. Sixteen (16) unrelated SSPE patients between ages 3-26 years and in various clinical stages were included in this study. Demographic data were described. Intraventricular instillation of ribavirin (1-3 mg/kg/dose) through an Ommaya reservoir was given for a duration of 3-6 months in 13 patients. The duration of follow-up was 48 weeks. The clinical outcome was assessed before, during, and after treatment using the Neurological Disability Index (NDI), Brief Assessment Examination (BAE), and clinical staging using the Jabbour Classification. Adverse side effects from intraventricular ribavirin were enumerated.

Results. Six of 13 (46.15%) patients mostly in Stage III illness had clinical improvement showing decreasing NDI and BAE scores during treatment and the clinical improvement was maintained or improved further during the 48-week follow-up period. Clinical improvement manifested as improved mental alertness, decrease in spasticity and reduction of seizures. The clinical staging of those who improved remained stable during and after treatment was discontinued. Five (38.46%) patients in Stage II disease worsened and progressed to Stage III despite ribavirin therapy including 1 (7.6%) patient who died after the treatment phase due to pneumonia and brainstem failure. The clinical course of two (15.38%) patients remained unchanged. Minor adverse side effects of ribavirin included transient fever, rash, oral sores, seizure episodes, drowsiness, bladder retention and mild increase in transaminases. Ommaya reservoir infection was a serious adverse event in 5 (31.25%) patients.

Conclusion. There is still no definitive cure for SSPE. Although ribavirin may help alleviate some of the symptoms of SSPE and prolong life, it may not reverse or halt the progression of the disease. Long term follow-up of these patients and continuous use of intraventricular ribavirin will better clarify its role in modifying the fatal course of SSPE. The role of ribavirin in Stage I patients and a controlled clinical trial in Stage II SSPE needs further studies.

Subacute sclerosing panencephalitis (SSPE) is a rare, progressive, and fatal central nervous system disorder resulting from persistent measles virus infection. Long-term data are scarce, with a maximum follow-up period of 10 years. Interferon-alpha (IFN-α) is a protein that exerts its antiviral activity via enhancement of cellular immune response and is reported to be an effective drug for the treatment of SSPE. However, there is currently no consensus regarding the optimal duration of IFN-α therapy. Here, we present a case report of a patient with SSPE treated with long-term intraventricular IFN-α therapy, which facilitated clinical improvement and neurological stabilization without causing serious adverse effects. To the best of our knowledge, this is one of the longest follow-up studies investigating a patient with SSPE receiving intraventricular INF-α treatment. Further studies are necessary to validate the benefits and safety of long-term intraventricular IFN-α treatment in patients with SSPE.

Measles is a highly contagious infectious disease characterized by fever, rash, cough, coryza, and conjunctivitis. The causative organism is the measles virus transmitted via the respiratory route. Before the introduction of an effective vaccine, measles was one of most prevalent diseases worldwide. Mortality may occur in patients with complications, including pneumonia, which is the most common cause of measles-associated death. The diagnosis of measles is based on clinical symptoms and laboratory tests, including the detection of measles virus-specific antibodies or measles virus ribonucleic acid and cultured viruses. The treatment for measles is primarily supportive care. In Korea, availability of the measles vaccine has substantially reduced the incidence and mortality of the disease. The World Health Organization verified the elimination of measles in March 2014; however, small outbreaks continue to be reported. Although a large proportion of measles cases occur in infants less than 1 year old, the disease has been reported in young adults with a history of measles vaccination. Here, we review the current literature on measles and discuss the importance of measles prevention in Korean adults.

Objective: To investigate the epidemiological characteristics of measles outbreak caused by genotype D8 virus in Pinghu city of Zhejiang province, and provide evidence for the control of the outbreak. Methods: The measles outbreak data were collected through National Measles Surveillance System. The outpatient records and admission records were checked, field investigation and outbreak response were conducted. Blood samples in acute phase and swab specimens were collected from the patients for laboratory testing, including serology test, RNA extraction and amplification, measles virus isolation and genotype identification. Software SPSS 17.0 and Excel 2016 were used for data analysis. Results: A total of 10 confirmed measles cases were reported in Pinghu city, and 8 cases were aged >40 years. Six blood samples were collected, in which 5 were measles D8 virus positive and 1 was negative in measles virus detection. There were epidemiological links among 10 cases which occurred in a factory, a hospital and a family at the same time. There was no statistical difference in symptoms among cases caused by D8 virus and H1a virus. After the emergent measles vaccination, the measles outbreak was effectively controlled. Conclusion: Untimely response due to the uneasy detection of measles cases in the early stage, nosocomial infection and weak barrier of measles immunity in adults might be the main reasons for this outbreak. Measles vaccination is effective in the prevention of measles D8 virus infection. It is necessary to strengthen measles genotype monitoring for the tracing of infection source and control of outbreaks.

OBJECTIVETo investigate the main factors that influence measles morbidity and the genotype of measles virus, so as to provide evidence for scientific decision making to further control the prevalence of measles.

METHODA retrospective analysis included 182 children in Children's Hospital of Fudan University, diagnosed with measles from January 1, 2012 to December 31. The clinical and epidemiological characteristics, including the gender, age, the incidence of seasonal trends, measles vaccine vaccination history, contact history and other clinical manifestations, laboratory test results, and so on were analyzed. And the reverse transcription PCR (RT-PCR) was adopted to detect sputum specimens from suspected patients with measles,who were selected randomly,the sequence of the part of the PCR products was analyzed.

RESULT(1) Clinical and epidemiological data: Totally were 182 children with measles (125 males, 57 females) were enrolled into this study. The age of the patients ranged from 3 months to 89 months, 127 cases were younger than 9 months (69. 8%). The prevalence season was from April to August, while the peak month was April and May (22. 5%, 23. 1%). Among 182 hospitalized children, only 11 cases underwent measles vaccination (6. 0%), and among them 5 cases were within 2 weeks before disease onset. A total of 167 cases (91. 8%) had not been vaccinated, most of whom were immigrants, and the measles vaccination history of the remaining 4 cases were unknown. There was a positive correlation between the measles vaccination ratio in children of the floating population (8. 45%, 6/71) and the settled children (29.4%, 5/17, χ =8. 11 P =0. 004). In total, 24 cases (13. 2%) had definite measles exposure history, with 153 cases (84. 1%) of unknown origin,5 cases (2.7%) without any history of contact. (2) Clinical manifestations: All the 182 patients had fever (100%) and obvious rashes (100%), among them 145 cases had body temperature higher than 39 °C (79. 7%). The fever period ranged from 2 to 38 days. Among 182 hospitalized children,165 cases (90. 7%) had typical measles,17 cases had atypical measles. Among the 17 cases, two had severe measles, one had heterotypic measles. (3) The common complica tions: 96 cases had pneumonia (52. 8%), 80 had laryngitis (44. 0%), 38 had bronchitis (20. 9%),15 had hepatic dysfunction (8. 2%), 11 had myocardial damage (6. 0%), 3 had febrile seizures (1. 6%), and no patient had encephalitis. Of the 96 cases with pneumonia, 92 received sputum test; 38 were sputum culture positive (41%). The dominant pathogens were Streptococcus pneumoniae(11/38,29%), Haemophilus influenzae (6/ 38,16%), Moraxella catarrhalis (4/38, 11%), Escherichia coli (4/38, 11%), Candida albicans (4/38, 11%), Mycoplasma pneumoniae (4/38, 11%) and Staphylococcus aureus (3/38, 8%). (4) The H1a genotype was the only one genotype in the detected sequence of 54 measles virus strains.

CONCLUSIONMeasles was more often seen in the children under the age of 9 months from the floating population. The morbidity peak month was from April to May in Shanghai. The H1a genotype was the only one genotype. We should try to improve vaccination coverage rate in the children who are at the age for vaccination, so as to prevent measles outbreak.

Oncolytic virotherapy is a novel cancer therapy. Vaccine-attenuated strains of measles virus(MV)is an ideal candidate for oncolytic virotherapy which has an excellent safety record. Vaccine-attenuated MV uses CD46 and Nectin-4 molecule as major entry receptors into cells. Vaccine-attenuated MV can selectively infect and kill a wide variety of cancer cells in vitro and in vivo. With the development of molecular cloning, scientists have successfully rescued cDNA of vaccine-attenuated MV and increased its oncolytic efficiency with molecular engineering techniques. Phase I clinical trials of virotherapy for ovarian cancer and multiple myeloma with vaccine-attenuated MV are underway. The preliminary results indicate the promising antitumor potential of vaccine-attenuated MV.

To wished to characterize the hemagglutinin (H) gene of the measles virus epidemic strain H1a in Liaoning Province (China) from 1997-2014 to provide a basis for the control and elimination of measles. All 63 measles virus strains were the H1a genotype. Fragments of the H gene (1854 nucleotides) and nucleoprotein (N) gene (450 nucleotides) were amplified by reverse transcription-polymerase chain reaction (RT-PCR) and the PCR products sequenced and analyzed. Phylogenetic-trees were constructed with reference strains of the genotype-H measles virus downloaded from GenBank, including Chinese measles virus strains isolated in 1993-1994 and the vaccine reference strains S-191 and C-47. Sixty-three strains of the measles virus in 1997-2014 belonged to genotype H1a. The mean evolutionary rate for gene N-450 was higher than that for the H gene. All 63 strains of the measles virus were mutated from: serine (Ser S) to asparagine (Asn N) in the 240th amino acid; arginine (Arg R) to glycine (Gly G) in the 243th; and tyrosine (Tyr Y) to Asn N in the 481th amino acid. All measles virus strains in cluster 2 were mutated from proline (Pro P) to leucine (Leu L) in the 397th amino acid. The other neutralization sites showed no apparent difference when comparing the nucleotides/amino acids of the H gene of S191 vaccine strains.
