“…is agent acts as a folic acid antagonist and is known to be an effective anti-in�ammatory agent. However, it is also known for its pulmonary toxicity which is independent of the dose delivered [1][2][3][4][5][6][7]. MTX-induced pulmonary toxicity is an unpredictable, unusual, and mostly reversible event.…”

Combined Lung Transfer of NO and CO in Patients Receiving Methotrexate or Bleomycin Therapy Compared to Normal Subjects

et al. 2013

e �rst aim of the study is to determine whether combined lung diffusing capacities of nitric oxide (TLNO) and of carbon monoxide (TLCO) are accurate in the followup of patients receiving either methotrexate (MTX) or bleomycin (BLM). e second objective is to determine whether TLCO, TLNO, KCO, and TLCO/VI% (inspiratory volume expressed as percentage of predicted value) correlate better with the diffusing capacity of the membrane (Dm) and/or capillary lung volume (Vc). TLNO and TLCO were measured in three groups: 22 "normal" subjects (N group), 17 patients receiving MTX, and 12 patients treated with BLM. TLCO, TLNO, Dm, and Vc were much lower in the MTX and BLM groups compared to those of the N one. e ratio TLNO/TLCO was higher in the BLM group compared to that of the N group and compared to that of the MTX group. KCO correlated neither with Dc nor with Vc, whereas TLCO/VI% correlated signi�cantly with both Dm and Vc. Combined measurement of TLCO and TLNO seems to be useful in the followup of patients receiving agents inducing lung toxicity and gives a good idea of the alveolar membrane and the capillary volume.
