LTA and sarcoidosis: A recent study in sarcoidosis patients revealed that there were positive correlations between EBC and BAL LT B4 levels and 8-isoprostane levels, higher EBC and BAL cysteinyl leukotriene (cysLT) and 8-isoprostane levels compared with normal subjects, positive correlations between EBC LT B4 levels and the number of BAL lymphocytes per milliliter and between the number and percentage of BAL eosinophils and EBC 8-isoprostane and BAL cysLT levels, and no correlation between EBC eicosanoid levels and BAL macrophages, BAL lymphocytes, or superoxide production percentages [148].
