    Alterations of Serum Copper and Zinc Levels, and Copper/Zinc Ratios Among Patients with Brucellosis
    (Ortadogu Ad Pres & Publ Co, 2012) Ustun, Cemal; Tegin, Ibrahim; Geyik, Mehmet Faruk
    Objective: To determine the alterations of serum copper (Cu) and zinc (Zn) levels and Cu/Zn ratio in patients with brucellosis. Material and Methods: A total of 170 individuals were included in the study. Of these, 45 (26.5%) currently had acute or sub-acute brucellosis, 35 (20.6%) were previously diagnosed with acute or sub-acute brucellosis and successfully treated, and 90 (52.9%) were healthy volunteers. After fasting overnight for 10 hours, 5 ml of venous blood was taken from all subjects. Serum Cu and Zn levels were measured using a Unicam 929 Atomic Absorption Spectrophotometer. SPSS 16.0 was used for data analysis. Results: Mean serum Cu levels of 45 patients with acute or sub-acute brucellosis, 35 patients previously diagnosed with acute or sub-acute brucellosis and 90 healthy volunteers were 88.6 +/- 26, 58.7 +/- 13 and 56.7 +/- 16 mu g/dL, respectively. Mean serum Zn levels of 45 patients with acute or sub-acute brucellosis, 35 patients previously diagnosed with and treated successfully for acute or sub-acute brucellosis and 90 healthy volunteers were 38.3 +/- 12, 58.5 +/- 14, and 55.8 +/- 13 mu g/dL, respectively. Serum Cu levels (p<0.001) and Cu/Zn ratios (p<0.001) were statistically significantly higher while serum Zn levels (p<0.001) were lower in patients with acute or sub-acute brucellosis when compared to the individuals who previously diagnosed with acute or sub-acute brucellosis and the healthy volunteers. Conclusion: This study revealed significant alterations of serum Cu and Zn levels, and Cu/Zn ratios in patients with acute or sub-acute brucellosis. Serum Cu, Zn, and Cu/Zn ratios may be available biomarkers in the course of acute or sub-acute brucellosis.

    The role of trace elements in wagner classified diabetic patients
    (Academic Journals, 2011) Bozkurt, Fatma; Gulsun, Serda; Ustun, Cemal; Geyik, M. Faruk; Tegin, Ibrahim; Satici, Omer
    Wagner's classification is the most widely used grading system in diabetic foot infections. The aim of this study was to evaluate the role of the trace elements in diabetic foot infected patients graded with Wagner's classification. This prospective study was carried out on 50 diabetic patients with variable severity of foot infections and 50 age and sex matched healthy subjects in Dicle University, Turkey, between October 2006 and November 2008. Diabetic foot infections were graded according to Wagner classification and deep tissue cultures were performed from all diabetic foot infected patients. The atomic absorption spectrophotometer was used in the measurement of trace elements in the serum. serum zinc and copper levels were significantly elevated in patients with Wagner 3 and 4 compared to Wagner 2 and 1 graded patients and healthy controls. Also Wagner 1 and 2 graded patients had higher serum zinc levels compared to healthy controls (p < 0.001). This study confirms that trace elements may be used as a leading sign to determine the severity of infections in diabetic foot wounds and may be used to predict outcome of diabetic foot infections.
