title: Increased luminol-enhanced chemiluminescence of blood monocytes and granulocytes in Hodgkin's disease.
abstract: The oxidative metabolic burst of blood monocytes and polymorphonuclear leukocytes (PMN) from 22 untreated patients with Hodgkin's disease (HD) and 18 healthy subjects were studied. Monocytes and PMN were enriched by density centrifugation and in vitro activated by zymosan. The oxidative metabolism was measured by luminol-enhanced chemiluminescence (CL). The CL of the patients' monocytes and PMN was higher than that of controls (P less than 0.01 and P less than 0.05, respectively). Patients with stage II-IV HD showed an increased blood monocyte CL as compared with stage I patients (P less than 0.05). Furthermore, patients with lymphocytic depletion or mixed cellularity subtype demonstrated an increased CL of PMN as compared with the remainder. Enhanced CL of phagocytes has been observed in chronic inflammatory disease and can be induced by various serum factors such as monokines and immune complexes. The present study demonstrates an increased CL of blood-borne phagocytic cells in untreated HD. Furthermore, CL of blood monocytes and PMN correlated to tumour burden and histologic subtype, respectively.
