简要总结
Infants are placed on ECMO for correction of reversible respiratory failure. Often, because a few of the reasons for respiratory failure show us similar things in the baby, it is difficult to determine exactly which is causing the biggest problem. We are now capable of measuring certain cells and proteins in these infants that may help us more accurately diagnose the exact problem. We hypothesize that infants placed on ECMO will show unique antibody-secreting cells responses and patterns of cytokine and chemokine (protein) response to illness and to the ECMO circuit. If we find unique patterns to these cells or proteins, they may be able to predict outcomes or guide treatment of these infants.
详细描述
Specific Aims Primary Objective
- Determine the rise, peak, and fall of immunoglobulin isotype-specific ASC's, and immunoactive proteins (cytokines and chemokines) from sequential samples of peripheral blood from infants on ECMO.
Secondary Objectives:
- Determine the most appropriate time to sample blood from infants with suspected sepsis for ASC diagnostic assay.
- Characterize the incidence of culture-negative sepsis that leads to ECMO.
- Determine immunoglobulin isotype-specific levels of ASC in infants with and without infection.
- Establish an archive of mononuclear cells and plasma to use in development of pathogen specific ASC assays.
Hypothesis Infants on ECMO will have a high ASC response and unique cytokine/chemokine patterns due to possible underlying infection and exposure to many foreign antigens (blood products, ECMO circuit). A significant portion of these will have ASC's with specificity for common causes of neonatal sepsis that is not detected by routine blood culture.
