Xpression. When plotting RSS vs. the percentfindings in adjustments of T-cell cytokine expression. When plotting RSS vs. the percentage of age of CD4+IL-6+ obtained for each and every every single patient both pre- and post- steroid initiation, we CD4+IL-6+ cells cells obtained for patient each pre- and post- steroid initiation, we noted noted a statistically substantial constructive correlation3, r = 0.47, pr= 0.01).

These information a greater a higher RSS is with enhanced relative presence of presence of CD4+/IL-6+ cells. These information suggest that dexamethasone remedy influences T-cell IL-6 secretion, which recommend that dexamethasone treatment influences T-cell IL-6 secretion, which is linked iswith a reduction in reduction in RSS. linked having a RSS.Kids 2021, eight, Kids 2021, eight, 879x FOR PEER REVIEW7 of 107 ofFigure three. Tracheal aspirate (TA) cell phenotype of CD4+IL-6+ cells was substantially correlated with respiratory severity Figure three. Tracheal aspirate (TA) cell phenotype of CD4+IL-6+ cells was substantially correlated with respiratory severity score (RSS, MAP FiO2). As RSS decreased, the % of CD4+IL-6 cells decreased, suggesting alterations inin inflammation score (RSS, MAP FiO2). As RSS decreased, the percent of CD4+IL-6 cells decreased, suggesting alterations inflammation represented by CD4+IL-6+ expression vital for clinical respiratory status.

Discussion study, we aimed to discover no matter if remedy with dexamethasone leads In this pilotto a In this pilot study, we aimed to discover no matter if remedy with dexamethasone leads alter in T-cell populations or cytokine expression in TA of mechanically ventilated premature in T-cell populations or assistance expression in that dexamethasone treatto a changeinfants. The resulting datacytokine our hypothesis TA of mechanically ventilated ment does infants.
