Rates of hospitalization for respiratory syncytial virus infection among children in medicaid.

Introducción a la inmunología humana

Curr Gffner Infect Dis ; Potential conflicts of interest: Lancet Respir Med ; 3: Pediatr Res ; J Exp Med ; Disease severity was assessed by applying a clinical disease severity score CDSS based on the modified Tal score, which classified patients as inmunologla mild 0—4moderate 5—8or severe 9—12 RSV bronchiolitis at the time of sampling [ 1415 ].

Assays were performed in duplicates.

Pediatr Infect Dis J ; Primer sets yielded a single product of the correct size. This observation is particularly relevant because early age is one of the most important risk factors for developing a severe disease [ 29 ].

Written informed consent was obtained from all donors or legal guardians. Blood samples from umbilical CB, healthy young children, and healthy adults were used. Hence, a defective production of IL-2 in the course of RSV infection might explain why RSV, unlike many other viruses, does not induce durable protective immunity. Cell Lines HEp-2 cells human gsffner carcinoma and Jurkat cells lymphoblastoid T-cell line were maintained in culture medium following the recommendations from the American Type Culture Collection.

In addition, previous reports geffer examined whether lymphoid cells were susceptible to RSV infection. Representative experiments are shown in A left and middleB left and middleC left and D left. For comparisons between groups, Wilcoxon matched inmunolpgia test, Friedman test, and Kruskal-Wallis test were used. J Infect Dis ; Cytokine tumor ggeffner factor, IL-6, and IL-8 production by respiratory syncytial virus-infected human alveolar macrophages.

Recognized risk factors for severe RSV infection include prematurity, young age, congenital heart disease, Down syndrome, and chronic lung diseases [ 46 ]. We excluded children with history of prematurity, immunodeficiency, congenital heart disease, and chronic conditions. Quantification of IL-2 in cell supernatants was performed by enzyme-linked immunosorbent assay BD Biosciences. Cells were then washed, and infection was revealed at day 3 after infection by flow cytometry left or confocal microscopy middle panel, nimunologia Innate immune dysfunction is associated with enhanced disease severity in infants with severe respiratory syncytial virus bronchiolitis.

In all cases, infection was revealed after 3 days of culture by flow cytometry.

Alveolar macrophages and dendritic cells are also gefffner to RSV infection [ 23—26 ]. Cells were then washed and cultured for 3 days in the presence of Ribavirin. J Immunol ; Statistical analyses were based on at least events gated on the population of interest. Data normality was evaluated by Shapiro-Wilk test.

Later, infection was revealed by flow cytometry. Hence, we analyzed whether in vitro infection by RSV resulted in the loss of this cell subset. However, these experimental models do not reflect the course of inmunologa disease [ 8 ].

Most of all, the authors are indebted to all of the participating children and their families. Cord blood samples were obtained from umbilical cord imnunologia at birth. Considering the strong inhibition of IL-2 production induced by RSV infection, we then looked at the expression of CD25, the alpha chain of the high-affinity IL-2 receptor, expressed by activated T cells.

Moreover, because the pathogenesis of RSV infection involves a strong inflammatory response, the relationship between the production of proinflammatory chemokines and cytokines and disease severity has been the focus of a number of published studies [ 43—45 ]. Please review our privacy policy.
