Сокращение иммуноглобулина M после первичной кори, свинки и краснухи.

Обнаружение иммуноглобулина M (IgM) с учетом особенностей кори стало стандартным методом диагностики для лабораторного подтверждения кори. В случаях вспышек интерпретация положительного результата IgM может быть затруднена, когда лица, подозреваемые в кори, получают дозу вакцины от кори в рамках мер по борьбе с вспышкой. В ходе этого исследования была проведена оценка разложения специфических для кори антител IgM через 1-4 месяца после первичной вакцинации корью, свинкой и вакциной против краснухи (MMRII). В рамках исследования по оценке отказа от первичной и вторичной вакцины против кори были

Detection of measles-specific immunoglobulin M (IgM) has become the standard diagnostic method for laboratory confirmation of measles. In outbreaks, the interpretation of an IgM-positive result can be complicated when persons with suspected measles receive a dose of measles vaccine as part of outbreak control measures. This investigation evaluated the decay …

Measles pneumonitis following measles-mumps-rubella vaccination of a patient with HIV infection, 1993.

The Advisory Committee on Immunization Practices (ACIP) recommends measles-mumps-rubella vaccine (MMR) for all persons asymptomatically infected with human immunodeficiency virus (HIV) and recommends that MMR be considered for all symptomatic HIV-infected persons who would otherwise be eligible for measles vaccine, because measles virus infection can cause severe illness and death in such persons. Serious or unusual adverse events in HIV-infected persons after receiving MMR have not been reported previously. This report summarizes the investigation of a case of progressive vaccine-associated m…

Measles immunisation compliance: poor impact of bicentennial measles control campaigns on children under five.

A measles immunisation survey was conducted among children who enrolled in school kindergarten classes in the Eastern Sydney Area in 1989. Its aims were to determine baseline compliance rates, to identify subpopulations at risk of poor compliance and to evaluate the impact of the bicentennial measles control campaigns on compliance among children under five years. All 73 schools participated, questionnaires were returned by 2230 (81.4%) children, and compliance with immunisation was 91.3%. 89.1% of children attending public schools were immunised, compared to 91.9% of Catholic school pupils an…

Population-based study of measles and measles immunization in human immunodeficiency virus-infected children.

This study reports the course of measles and results of measles immunization in a cohort of human immunodeficiency virus-infected children. Six cases of measles were identified. All had typical clinical manifestations, 5 of 6 developed pneumonia and 3 of 6 died. A measles intervention program consisting of serologic screening and active immunization (measles-mumps-rubella (MMR)) was instituted in 1990. Among 127 children with data available for analysis (mean age, 6.7 years), only 35% had documentation of prior immunization with MMR. Among 80 children who had preimmunization measles serology r…

Development of antibody to measles virus polypeptides during complicated and uncomplicated measles virus infections.

Immune precipitation of 181 sera from 152 patients with natural measles was studied to determine the temporal course and frequency of antibody responses to nucleocapsid, fusion, hemagglutinin, and matrix proteins of measles virus. Large amounts of antibody to nucleocapsid protein developed in all patients by day one of the rash. Antibody to hemagglutinin and fusion proteins developed in all patients over the next 3 weeks, the former to high levels and the latter to low levels. Antibody to matrix protein developed to very low levels and was detectable in only 41% of the patients; this poor resp…

Measles virus and subacute neurological disease: an unusual presentation of measles inclusion body encephalitis.

A 20-year-old girl developed a subacute neurological illness characterized by seizures and epilepsia partialis continua, which resulted in her death within 10 weeks of her first symptom. Although she had a history of unusual reactions to viral infections, there was no evidence of any underlying disorder resulting in immunosuppression. Histopathology demonstrated the presence of dense infection with measles virus. The unusual clinical features of this cases suggest that measles virus may be responsible for a wide spectrum of neurological disease ranging from measles inclusion body encephalitis …

Comparison of measles plaque reduction neutralization test (PRNT) and measles virus-specific IgG ELISA for assessment of immunogenicity of measles-mumps-rubella vaccination at 5-7 months of age and maternal measles antibodies.

BACKGROUND: Assessing the risk of measles outbreaks and identifying the susceptible parts of the population is essential to timely intervention. Infants between 6-12 months are increasingly susceptible to measles but evaluating the performance of high throughput enzyme immunoassays (ELISAs) in infants < 9 months of age is lacking. METHODS: A commercially available ELISA kit (Creative Diagnostics, DEIA359) for estimating measles seroprotection was evaluated in infants 5-7 months of age. In an immunogenicity substudy in the Danish MMR trial conducted between 2019-2021, infants (and mothers at b…

Difficulties in eliminating measles and controlling rubella and mumps: a cross-sectional study of a first measles and rubella vaccination and a second measles, mumps, and rubella vaccination.

BACKGROUND: The reported coverage of the measles-rubella (MR) or measles-mumps-rubella (MMR) vaccine is greater than 99.0% in Zhejiang province. However, the incidence of measles, mumps, and rubella remains high. In this study, we assessed MMR seropositivity and disease distribution by age on the basis of the current vaccination program, wherein the first dose of MR is administered at 8 months and the second dose of MMR is administered at 18-24 months. METHODS: Cross-sectional serological surveys of MMR antibodies were conducted by collecting epidemiological data in Zhejiang province, China i…

The effect of live, attenuated measles vaccine and measles infection on measles antibody levels in serum and CSF of patients with multiple sclerosis or clinically isolated syndrome.

High occurrence of measles, rubella and varicella zoster antibodies has been used as a biomarker for MS (the MRZ test). We analyzed measles antibody titres with respect to measles infection/measles vaccination status in 166 patients with MS or clinically isolated syndrome. Fifty blood donors served as controls. Measles vaccination yielded CSF measles antibodies in fewer patients (62%) than measles infection did (87%, p=0.001) and yielded lower measles titres in both serum and CSF (p<0.001). Controls had lower CSF measles titres than patients with measles vaccination alone (p<0.001). Childhood …

Variability in Recommendations for Measles, Mumps, Rubella Vaccination, and Vitamin A Administration in the Setting of Measles Outbreaks.

A survey of Emerging Infections Network members conducted in June 2025 of 169 pediatric infectious disease physician respondents practicing in the United States demonstrated that risk assessments drove pre-travel measles, mumps, rubella vaccine recommendations. Hospitalization, oral formulation availability, oral administration, and vitamin A deficiency influenced vitamin A recommendations.

Etiological analysis of discarded measles in the context of a measles outbreak among a highly immunized population.

BACKGROUND: Measles can lead to serious complications and remains an important cause of morbidity and mortality worldwide. In this study we aimed to assess the etiological diagnosis of discarded measles cases in the context of an outbreak among a highly immunized population. METHODS: We conducted a retrospective observational study of discarded measles cases from an outbreak that occurred from October 2006 to July 2007 in Catalonia. A confirmed case was defined as having a positive measles serum IgM result and/or a positive result by RT-PCR in urine and/or nasopharyngeal swab; or an epidemiol…

A study on relationship between the incidence of measles and nosocomial exposure at measles epidemic season in Chongqing.

After measles vaccine supplementary immunization, the epidemiological characteristics of measles have changed in Chongqing, China. In addition, according to data from the National Measles Surveillance Information System, the proportion of measles cases with a history of hospital visit 7 to 21 days prior to onset of measles increased year by year to 32.1% in 2016. Further studies are necessary to eliminate the influence of nosocomial exposure on measles. We performed a case-control study in seven districts of Chongqing from June to August 2016 to identify risk factors for measles virus infectio…

Measles seroprevalence in human immunodeficiency virus-infected adults born in the era of measles vaccination.

OBJECTIVE: Widespread use of the measles vaccine should lead to the elimination of this disease. Here, we study the seroprevalence of measles in a cohort of adults living with HIV born after the introduction of measles vaccine in France and attempt to identify risk factors for the absence of serum measles antibody. DESIGN: In this multi-centre cross-sectional study, adult outpatients born after 1980 were screened for the presence of measles IgG antibody. Demographic and clinical data were obtained from the standardized electronic medical record system. Univariate and multivariate logistic reg…

High risk of a large measles outbreak despite 30 years of measles vaccination in The Netherlands.

Our aim was to assess progress towards measles elimination from The Netherlands by studying humoral measles immunity in the Dutch population. A population-based seroepidemiological study was conducted in 2006-2007 (N = 7900). Serum samples were analysed by a bead-based multiplex immunoassay. IgG levels ⩾0·2 IU/ml were considered protective. The overall seroprevalence in the Dutch population was 96%. However, 51% of socio-geographically clustered orthodox Protestant individuals aged <10 years were susceptible. Infants might be susceptible to measles between ages 4 months and 14 months, the age …

Detection of measles virus genomic RNA in tear samples from a patient with measles keratitis.

PURPOSE: To report a case of measles keratitis, in which measles virus genomic RNA was detected in tear samples. METHODS: Samples of tears and pharyngeal mucus were obtained from a 19-year-old man with active systemic measles on day 7 after illness onset. These specimens were then subjected to reverse-transcriptase polymerase chain reaction (RT-PCR), using measles-specific primers. RESULTS: One week after systemic measles outbreak, the patient presented with a chief complaint of irritation in both eyes. Slit-lamp examination revealed bilateral superficial punctate keratopathy in the central …

Measles vaccine efficacy study in a Canberra high school: a study following a measles outbreak.

An outbreak of measles which occurred in Canberra between October and December, 1991, was investigated to estimate the public health utility of the vaccine. The measles vaccine efficacy was determined for the 13-15 year old children in a selected high school. During the outbreak, at least 82 Canberra children contracted measles. Teenage males accounted for 56% of total cases, and 22% of cases were confirmed by serology. The vaccine coverage in the high school studied decreased with increasing school years, varying from 85.8% in Grade 8 to 79.2% in Grade 10. The highest attack rate occurred in …

Acute measles in patients with and without neurological involvement: distribution of measles virus antigen and RNA.

Using peroxidase immunohistochemistry and in situ hybridization to localize viral antigen and RNA, we studied autopsy tissues from 20 cases of acute fatal human measles (including seven patients with acute encephalomyelitis) and peripheral blood mononuclear cells from 16 patients with acute, nonfatal measles. In immunologically normal patients, virus was detected in five of nine who died five days or less after the onset of rash but in none of 11 who died later. Virus was localized to epithelial cells of lung, gut, bile duct, bladder, and skin and to lymphoid organs. Neither viral antigen nor …
