C. Haberthur et al., PNEUMOCYSTIS-CARINII PNEUMONIA UNDER THER APY WITH 2-CHLORODEOXYADENOSINE (2-CDA), Schweizerische medizinische Wochenschrift, 124(1-2), 1994, pp. 73-78
We report the case of a 70-year-old patient with B-cell chronic lympho
cytic leukemia. During therapy with the new purine analog 2-chlorodeox
yadenosine (2-CDA) the patient developed Pneumocystis carinii pneumoni
a (PCP). Although the mechanism of action of 2-CDA suggests the incide
nce of opportunistic infections and therefore pneumocystis pneumonia,
this is the first case of PCP among 140 patients of the Swiss study of
2-CDA. The mechanism of action of 2-CDA is described and the occurren
ce of PCP among patients without acquired immunodeficiency syndrome is
discussed.
