passages.text: Four out of 23 consecutive patients treated with high-dose Ara-C for lymphomas in our institution developed a strikingly similar syndrome during the perfusion. It was characterized by the onset of fever, diarrhea, shock, pulmonary edema, acute renal failure, metabolic acidosis, weight gain and leukocytosis. Thorough bacteriological screening failed to provide evidence of infection. Sequential biological assays of IL-1, IL-2, TNF and PAF were performed during Ara-C infusion to ten patients, including the four who developed the syndrome. TNF and PAF activity was found in the serum of respectively two and four of the cases, but not in the six controls. As TNF and PAF are thought to be involved in the development of septic shock and adult respiratory distress syndrome, we hypothesize that high-dose Ara-C may be associated with cytokine release.
