Angiotensin-converting enzyme: an indicator of bleomycin-induced pulmonary toxicity in humans?

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningfagfællebedømt

In order to evaluate bleomycin-associated lung damage in humans, lung function parameters and serum levels of the endothelial-bound angiotensin-converting enzyme (ACE) were determined by serial measurements in 11 patients who were treated for testicular cancer. None developed clinical or radiological evidence of pulmonary damage. While the static and dynamic lung function parameters were unchanged, carbon monoxide diffusion capacity (DLCO) decreased significantly (P less than 0.01) during a total of 126 days of pulsed regimen, indicating damage to the alveolar-endothelial membrane. S-ACE was unchanged within each treatment course but increased significantly (P less than 0.05) from the initial value to the last treatment course. Two months after cessation of treatment S-ACE returned to pretreatment values. Although the changes were modest they might mirror treatment-associated endothelial damage.
