The increased survival rate of malignant diseases due to more aggressive treatments contributes to the occurrence of drug‐induced pulmonary diseases (DIPD). We reviewed, retrospectively over a 10‐year period, 15 children (8 girls) who presented a DIPD. Their mean age was 9 years (range, 1 to 17 years), with an underlying malignant disease in 14 (9 leukemias). Three typical patterns have emerged from this analysis: (1) acute hypersensitivity lung disease caused by methotrexate (in 6 patients) or azathioprine (in 1 patient). This acute syndrome consisted of alveolar‐interstitial infiltrate with a hypercellularity on bronchoalveolar lavage (BAL) (mean, 714,286 cells/mL; range, 180,00—2,940,000 cells/ml) and an increase of lymphocyte counts (mean, 39%; range 1144%) with predominantly CD8‐suppressor/cytotoxic lymphocytes. Inhibition of leukocyte migration or leukocyte aggregation in the presence of low drug concentrations was positive in the 5 cases tested. Lung function tests showed a restrictive pattern and the outcome of DIPD was always favorable. (2) Chronic pneumonitis/fibrosis was seen in 6 patients who received a variable association of cyclophosphamide (3 patients), bleomycin (2 patients), BCNU (2 patients), and melphalan (1 patient). Symptoms of an alveolar‐interstitial pneumonitis developed progressively. BAL showed a moderate increase of total cell numbers (mean, 495,000 cells/mL; range, 150,000—900,000 cells/mL). Lung function tests showed a restrictive pattern. Despite corticosteroid treatment in 4 children, one died after bleomycin lung injury and 2 had functional lung impairment. (3) Noncardiogenic pulmonary edema occurred in 2 patients with leukemia treated with recombinant interleukin II. BAL showed hypercellularity and outcome was rapidly favorable. This study reports on the occurrence and severity of DIPD in infants and children. DIPD may be underdiagnosed because of inefficiencies in systematic lung evaluation in children treated with cytotoxic drugs. Pediatr Pulmonol. 1994;18:347–355. ©1994 Wiley‐Liss, Inc.
