Thymus and activation regulated chemokine (TARC) is a predicting factor for development of bronchiolitis obliterans syndrome (BOS). (a) Prior to transplantation, no significant differences can be seen with regard to freedom from BOS between, respectively, the 21 versus 23 patients with serum TARC levels above versus below 590 pg/ml. (b) The 30 patients with serum TARC levels above 325 pg/ml in the first month post-transplantation show a significantly higher freedom of BOS (P = 0·001) compared with the 14 patients with serum TARC levels below this concentration.
