Seroprevalence of mumps among children and adolescents in Thailand, 2020.

Thailand has implemented single-dose mumps-containing vaccines since 1997 and two doses since 2010. This study aimed to describe the seroprevalence of mumps among children who received one- or two-dose mumps vaccines. A cross-sectional study of 145 children (aged 3-9 years) and 422 adolescents (10-18 years) was conducted. Mumps IgG seropositivity was defined as ≥ 22 RU/mL by EUROIMMUN ELISA method. The mumps seroprevalence was higher in children (82.1%, 95% CI 74.8-87.9) compared to adolescents (41.7%, 95% CI 37.0-46.6) who had received at least one dose of the mumps vaccine. Among those recei

Vaccination rates for Syrian population under temporary protection in Turkey.

OBJECTIVES: The aim of this study was to gather information on demographic and health indicators, primarily vaccination status, of Syrians u … nent combined vaccine (64.6%); conjugated pneumococcal vaccine (58.0%); oral polio vaccine (70.8%); measles, mumps, and rubella (76.6%); varicella (66.8%); and hepatitis A vaccine (76.0%). CONCLUSION: It is important to increase the immunization rates of Syrian children under temporary protection and establish regular vaccination procedures.

Immunization status and re-immunization of childhood acute lymphoblastic leukemia survivors.

Intensive chemotherapy can cause long-lasting immunosuppression in children who survived cancer. The immunosuppression varies according to t … stic leukemia (ALL) cases before and after the intensive chemotherapy treatment. Antibodies against measles, mumps, rubella, varicella, hepatitis A and B were tested with the enzyme-linked immunosorbent assay (ELISA) method. Antibody titers were measured firstly at the leukemia diagnosis time when the chemotherapy was not started. The second evaluation of …

Seroprevalence and Determinants Associated with Mumps Antibodies after 20 Years of MMR Vaccination in Urban Area of Shanghai, China.

A resurgence of the mumps epidemic in highly vaccinated populations has occurred in recent years in many countries. This study aimed to evaluate the seroprevalence to mumps in urban areas of Shanghai, where a measles-mumps-rubella (MMR) vaccination had been implemented for 20 years. Mumps IgG antibodies were tested in 2662 residual sera from all ages in an urban area of Shanghai. A linear regression method was performed to assess the persistence of mumps antibodies after MMR vaccination. A logistic regression method was used to analyze the variables associated with seronegative sera. The overa…

При наборе CD8+T лимфоцитов, специфичных для периферической вирусной инфекции, спровоцируется нейропаогенез во время полимикробного вызова.

Хотя вирусы были замешаны в неизвестных заболеваниях центральной нервной системы (СНС), включая множественный склероз и амиотропический боковой склероз, воспроизводимая идентификация вирусных спусковых устройств в таких заболеваниях в значительной степени оказалась безуспешной. Здесь мы исследуем гипотезу о том, что вирусы не должны воспроизводиться в ткани, в которой они вызывают болезни; в частности, что периферическая инфекция может вызвать патологию CNS. Чтобы проверить эту идею, мы использовали трансгенную модель мыши, в которой мы обнаружили, что иммунные клетки, реагирующие на периферич

In this model, mice are infected with both CNS-restricted measles virus (MV) and peripherally restricted lymphocytic choriomeningitis virus (LCMV). While infection with either virus alone resulted in no illness, infection with both viruses caused disease in all mice, with ∼50% dying following seizures. Co-infectio …

Clinical epidemiology of inflammatory bowel disease: Incidence, prevalence, and environmental influences.

Although the incidence and prevalence of ulcerative colitis and Crohn's disease are beginning to stabilize in high-incidence areas such as northern Europe and North America, they continue to rise in low-incidence areas such as southern Europe, Asia, and much of the developing world. As many as 1.4 million persons in the United States and 2.2 million persons in Europe suffer from these diseases. Previously noted racial and ethnic differences seem to be narrowing. Differences in incidence across age, time, and geographic region suggest that environmental factors significantly modify the expressi

Cases of aseptic meningitis after vaccination against mumps in Russia (2009-2019).

OBJECTIVES: Mumps is a highly contagious viral infection prevented by immunization with live attenuated vaccines. Mumps vaccines have proven to be safe and effective; however, rare cases of aseptic meningitis (AM) can occur after vaccination. The range of meningitis occurrence varies by different factors (strain, vaccine producer, and so on). Monovaccines or divaccines (mumps-measles vaccine), prepared from the strain Leningrad-3 (L-3), are used in Russia. Meningitis occurrence after vaccination has been established previously as very low. Nevertheless, with the number of children being vaccin…

The value of tailoring vial sizes to populations and locations.

BACKGROUND: Frequently, a country will procure a single vaccine vial size, but the question remains whether tailoring the use of different size vaccine vial presentations based on populations or location characteristics within a single country could provide additional benefits, such as reducing open vial wastage (OVW) or reducing missed vaccination opportunities. METHODS: Using the Highly Extensible Resource for Modeling Supply Chains (HERMES) software, we built a simulation model of the Zambia routine vaccine supply chain. At baseline, we distributed 10-dose Measles-Rubella (MR) vials to all…

Low serum levels of interleukin-6 in children with post-infective acute thrombocytopenic purpura.

Interleukin-6 plays an important role in host defense mechanisms and it appears to be a major mediator of the acute-phase response. IL-6 is also an important thrombocytopoietic factor. High serum levels of IL-6 are present in reactive thrombocytosis. The number and function of circulating platelets are the major factors that affect megakaryocytopoiesis by thrombopoietin. High levels of thrombopoietin have been observed in patients with thrombocytopenic purpura. To evaluate a possible thrombopoietin-like function of IL-6, we measured IL-6 levels in the serum of patients affected by post-infecti
