title: Evaluation of the cardiovascular toxicity related to cancer immunotherapy with interleukin-2 by monitoring atrial natriuretic peptide secretion: a case report.
abstract: Increased capillary permeability and severe hypotension represent the two major cardiovascular complications of IL-2 immunotherapy. The mechanisms responsible for IL-2 cardiovascular toxicity are still obscure. Since increased vascular permeability and vasodilatation may be also induced by the cardiac hormone atrial natriuretic peptide (ANP), we have evaluated ANP concentrations in relation to mean arterial pressure in one patient with metastatic renal carcinoma, treated with a 24-h intravenous infusion of IL-2 at a dose of 3 x 10(6) Cetus U/m2/day for 5 days. The results showed that episodes of important hypotension were associated with abnormally high plasma levels of ANP. Owing to its vasodilator activity, exaggerated ANP secretion, perhaps due to an inappropriate cardiac endocrine function in response to hemodynamic changes induced by IL-2, may play a role in hypotension, which occurs during IL-2 immunotherapy for cancer.
