Oxidase activity of ceruloplasmin and some acute phase reactant and trace element concentrations in serum of patients with chronic lymphocytic leukemia

In the present study, we aimed to investigate the parameters in serum of patients with chronic lymphocytic leukaemia (CLL) and correlate with the cancer stage. The serum concentrations of ceruloplasmin, a-1-acid glycoprotein, albuminumin, transferrin, copper, zinc, manganese, and ceruloplasmin oxidase activity were measured, and compared with those from a healthy control group. The serum from 34 patients with CLL were extracted before chemotherapy. Serum transferrin, allbuminumin and Zinc concentrations were lower in patients with CLL while serum a-1-acid glycoprotein, ceruloplasmin, copper concentrations, and ceruloplasmin oxidase activity were higher in CLL patients when compared with the control group. Although serum manganese concentration was lower in CLL groups than in the control group, the difference was not statistically significant. Serum transferrin concentration was lower in the early stage group compared with the advanced stage. Serum ceruloplasmin level positively correlated with serum ceruloplasmin oxidase activity in patients from the early stage group. Serum ceruloplasmin level positively correlated with serum ceruloplasmin oxidase activity in patients with advanced stage. In conclusion, increased serum ceruloplasmin oxidase activity, ceruloplasmin, a-1-acid glycoprotein, copper levels and decreased transferrin and albuminumin, unchanged manganese levels are associated with CLL and appear to be a consequence of the disease itself.
