The value of serum zinc, copper, ceruloplasmin levels in patients with gastrointestinal tract cancers.

BACKGROUND/AIMS: Gastrointestinal cancers are frequent diseases of particular importance for surgeons with regard to their management and follow-up. Neoplastic diseases activate antioxidant defense systems. As a result, concentrations of redoxal enzymes and their co-factor elements appear to change. The levels of zinc (Zn), copper (Cu) and ceruloplasmin have been found to be critical parameters. In addition, it seems to be important to consider the Cu/Zn ratio in such cases. In this study, changes in the levels of Cu, Zn and ceruloplasmin in patients with gastrointestinal system cancers was evaluated, and the proportion of Cu to Zn (Cu/Zn) is discussed. METHODS: In this clinical trial, levels of Cu and Zn were defined with calorimetric methods and ceruloplasmin levels were measured with immunohistochemical methods in a control group of 20 healthy individuals and in 25 patients who underwent surgery for gastrointestinal system cancer. The blood samples were taken preoperatively in gastrointestinal system cancer patients. RESULTS: This study has shown that while the decrease in Zn levels and the increase in ceruloplasmin levels in patients with gastrointestinal system cancers were found to be significant (p<0. 001, p=0. 014) when compared to the control group, the increase in the level of Cu was also found to be significant (p=0. 019). In the patient group, the correlations between serum Cu and serum ceruloplasmin proved to be significant (r=991, p<0. 001). The Cu/Zn ratio, when compared with Zn, ceruloplasmin and Cu, showed significant results (r= 0. 562, r= 0. 500, r=0. 506, p<0. 001). CONCLUSIONS: This study shows that serum Cu, Zn and ceruloplasmin levels show changes in gastrointestinal system cancers, but further research is needed to demonstrate the importance and significance of these parameters and their relation with other contributing neoplastic factors.     

Blood micronutrient, oxidative stress, and viral load in patients with chronic hepatitis C

AIM: To assess the extent of micronutrient and oxidative stress in blood and to examine their linkages with viral loads in chronic hepatitis C patients. METHODS: Hepatitis C virus (HCV)-RNA levels were quantified in the serum from 37 previously untreated patients with chronic hepatitis C. The plasma and erythrocyte micronutrients (zinc, selenium, copper, and iron) were estimated, and malondialdehyde (MDA) contents were determined as a marker to detect oxidative stress. Antioxidant enzymes, superoxide dismutase (SOD), glutathione peroxidase (GPX) and glutathione reductase (GR) activities in blood were also measured. The control group contained 31 healthy volunteers. RESULTS: The contents of zinc (Zn), and selenium (Se) in plasma and erythrocytes were significantly lower in hepatitis C patients than in the controls. On the contrary, copper (Cu) levels were significantly higher. Furthermore, plasma and erythrocyte MDA levels, and the SOD and GR activities in erythrocytes significantly increased in hepatitis C patients compared to the controls. However, the plasma GPX activity in patients was markedly lower. Plasma Se (R=-0.730, P<0.05), Cu (r=0.635), and GPX (r= -0.675) demonstrated correlations with HCV-RNA loads. Significant correlation coefficients were also observed between HCV-RNA levels and erythrocyte Zn (r=-0.403), Se (r = -0.544), Cu (r= 0.701) and MDA (P=0.629) and GR (r =0.441). CONCLUSION: The levels of Zn, Se, Cu, and oxidative stress (MDA), as well as related anti-oxidative enzymes (GR and GPX) in blood have important impact on the viral factors in chronic hepatitis C. The distribution of these parameters might be significant biomarkers for HCV.

Alterations of serum antioxidant trace elements (Se,Zn and Cu) status in patients with cutaneous leishmaniasis

ObjectiveTo assess the serum antioxidant trace elements selenium (Se), zinc (Zn) and copper (Cu) in cutaneous leishmaniasis patients.MethodsIn this study, serum Se, Zn and Cu was determined by using atomic absorption spectrometry in patients with cutaneous leishmaniasis (n=95). The values were statistically compared between patients and control group (n=100) using One-way analysis of variance (ANOVA).ResultsOur results showed that there was a significant difference in the values of Se and Zn between two groups (P<0.000 1 and P<0.01, respectively). Meanwhile, no significant difference in level of Cu was observed between patients and healthy subjects (P>0.05). Se and Zn levels were found to be (4.33±1.06) and (70.23±19.12) μg/dL in cutaneous leishmaniasis cases, and these values were found statistically lower compared to the controls (11.10±2.37) and (119.61±26.18) μg/dL, respectively.ConclusionsThe observations that host products are released from stimulated leukocytes and could induce metabolic changes similar to an acute-phase response revealed an endocrine role for the immune system. Characteristic changes in trace-mineral metabolism are an integral part of the acute-phase response. The changes are usually reflected in decreased serum Se and Zn concentrations.
