Abstract

The relationship between the content of metallothioneins, copper and zinc ions in peripheral blood plasma in chronic lymphocytic leukemia (CLL) depending on the disease progression was studied. It was shown that in patients with CLL in blood plasma with a progressive disease, partial and complete remission, the values of the zinc-to-copper ratios significantly decreased in comparison to similar indicators of practically healthy donors. It was established that in patients with CLL, the level of metallothioneins in blood plasma decreases with the disease progression compared to other studied groups, which indicates a reduced function of cysteine-containing metallothionein proteins. Based on the obtained data, it can be concluded that the zinc-to-copper concentration ratio and the level of metallothionenins in peripheral blood plasma are potential diagnostic and prognostic markers in chronic leukemia.
