Alcohol abuse is a well-known cause of imbalance in trace element levels and oxidant/antioxidant status of individuals with long time consumption. However, the levels of these parameters in the patients on the early stages of alcohol dependence without liver damage differ on various studies. The aim of our study was to measure the levels of trace elements in the serum and oxidative/antioxidative system members in the red blood cells (RBC) of early-stage alcoholic individuals and compare with control subjects. Our study included 21 male patients recently hospitalized for alcohol abuse and 25 healthy non-abusing male controls. Levels of Fe, Zn, and Cu in the serum and MDA, SOD, CAT, and GSH in the red blood cells (RBC) of the subjects were measured. Fe, Zn, and Cu levels were lower in the study group when compared to the controls. Levels of lipid peroxidation marker MDA was high, whereas the activities of antioxidant enzymes SOD and CAT were decreased in our study group. However, levels of GSH, an antioxidant compound were higher in the alcohol abuse group. RBC SOD levels were positively correlated with Fe, Cu, Zn, and CAT. There was a positive correlation between Fe-Cu, Zn-Fe, Zn-Cu, CAT-Zn, and CAT-SOD. MDA was negatively correlated with Fe, Zn, SOD, and CAT. The results obtained from present study indicate that high levels of alcohol intake are related with increased oxidative damage and decreased levels of antioxidant enzymes and trace elements. Additionally, antioxidant compensation mechanisms are still on process in the early stages of chronic alcohol exposure.
