[Seroprevalence of antibodies against measles virus in Galicia: trends during the last ten years depending on age and sex].

ABSTRACT: OBJECTIVE:In 1998, the Europe Region of the World Health Organization set the goal of eliminating measles. In this study, the prevalence of immunity against measles virus in the population of the health area of Santiago de Compostela was analyzed based on data obtained between 2008-2018. METHODS:A total of 7,150 different patients were studied and divided into groups according to their year of birth: 2010-2017, 2000-2009, 1990-1999, 1980-1989, 1953-1979 and <1953. The serum determination of IgG against measles virus was performed using a commercialized chemiluminescent immunoassay. RESULTS:A minimum (76%) was observed for measles virus protection rates in those born between 1990-1999. By age group it was seen that in all groups the women presented a higher percentage of antibodies against measles. In a logistic regression model with year of birth and sex, an odds ratio of 1.06 (p<0.001) was obtained for the year of birth and of 0.82 (p=0.0013) for sex. CONCLUSIONS:It was observed lower seroprevalences from the implantation of the vaccine and a more pronounced change during the implantation period. From the vaccination plan for measles of the year 2000 in Galicia, the rates of protection against the virus of the measles have been increasing in our area. Although there is a greater proportion of women protected against men, these differences are small.

Project description:ImportanceAlthough patients with cancer are at an increased risk of infection-related complications, few studies have characterized their vulnerability to measles and mumps. Given the recent outbreaks and increased community vaccine hesitancy, understanding measles and mumps immunity within this population is vital.ObjectivesTo identify a point prevalence estimate of protective measles and mumps antibodies among ambulatory patients with cancer.Design, setting, and participantsIn this cross-sectional study, residual clinical plasma samples were obtained from consecutive patients with cancer at Seattle Cancer Care Alliance/Fred Hutchinson Cancer Research Center in Seattle, Washington, in August 2019. These samples were tested for measles and mumps IgG using a commercial enzyme-linked immunosorbent assay. Patients without cancer were excluded from the analysis.ExposuresPatient age, sex, self-reported race and ethnicity, primary disease, receipt of chemotherapy in the past 30 days before sample collection, hematopoietic cell transplant (HCT) history, and date of most recent intravenous immunoglobulin treatment were abstracted from electronic medical records.Main outcomes and measuresMeasles and mumps IgG seroprevalence, defined as the proportion of patients with positive antibody test results, was measured overall and among the subgroups.ResultsOf the 959 patients included in the analysis, 510 (53%) were male individuals and the mean (SD) age at sample collection was 60 (15) years. Most patients (576 [60%]) had a malignant solid tumor, and 383 patients (40%) had a hematologic malignant neoplasm; 146 patients (15%) had an HCT history. Overall, the seroprevalence of measles antibodies was 0.75 (95% CI, 0.72-0.78), and the seroprevalence of mumps antibodies was 0.62 (95% CI, 0.59-0.65). The lowest seroprevalences were among patients with a hematologic malignant neoplasm (0.63 for measles and 0.48 for mumps), those with a history of HCT (0.46 for measles and 0.29 for mumps), and those aged 30 to 59 years (0.49-0.63 for measles and 0.41-0.58 for mumps).Conclusions and relevanceIn this study, 25% of ambulatory patients with cancer lacked protective antibodies for measles and 38% lacked protective antibodies for mumps. Deficits in protective antibodies underscore patients' increased risk during outbreaks and emphasize the need for community-based efforts to increase herd immunity to protect this population.
