Abstract

We analyzed the 67 of 278 patients with newly-diagnosed AML or 'high-risk' MDS, treated in 1994 and 1995, who developed pneumonia during course 1 of their induction therapy. Pneumonia responded to treatment in 66%, but outcome depended on when pneumonia was diagnosed. Patients with pneumonia diagnosed during week 1 or 2 (group 2 patients) had the lowest response rate (43%). Patients who developed pneumonia in the 3rd week after treatment initiation had the best outcome with all 16 patients recovering. Patients presenting with pneumonia had an intermediate response rate (75%). The different patient groups were comparable with regard to age, underlying disease, prophylactic therapy, and G-CSF application. Although a lower CR rate was not entirely responsible for the lower response rate in group 2, failure to achieve CR predicted unsuccessful treatment of pneumonia in all groups. Fungal pathogens appeared more common in group 2 patients. However, in these patients, administration of amphotericin B was associated with a significantly higher failure rate (15/21 failures vs 2/9 who received no amphotericin B). We conclude that patients who develop pneumonia during week 1 or 2 are a high-risk group, and that use of amphotericin B indi...Continue Reading
