[Acute pneumocystosis during polychemotherapy following the MACOP-B protocol].
Four out of eleven patients--none of them HIV positive--who received treatment for non-Hodgkin lymphoma by the MACOP-B protocol between June 1989 and February 1990 were taken ill during or shortly after the conclusion of the course with fulminant pneumonia necessitating artificial ventilation. In three cases Pneumocystis carinii was identified as the pathogen, and in one patient the diagnosis of pneumocystosis seemed probable. The mean cumulative doses given before the outbreak of pneumonia were as follows: cyclophosphamide 2753 +/- 1161 mg, methotrexate 1590 +/- 667 mg, bleomycin 36 +/- 16.8 mg and prednisone 4378 +/- 1734 mg. The mean haemoglobin concentration was 10.7 +/- 0.5 g/dl, leucocyte count 5250 +/- 2100/microliters, lymphocyte count 1300 +/- 300/microliters and lactate dehydrogenase 227 +/- 34 U/l. The cumulative doses and laboratory findings in the seven patients not affected by pneumocytosis were not significantly different. The patients with pneumonia were supported by mechanical ventilation for 6-26 days and treated with large doses of corticosteroids and co-trimoxazole. One patient died after 17 days' ventilation. Three patients were successfully weaned from the ventilator. Chemotherapy protocols such as MACOP-B predispose to acute Pneumocystis pneumonia. The risk of infection is independent of the cumulative doses of the drugs employed. For this reason, prophylaxis with co-trimoxazole is normally mandatory.
