Aim The aim of this study was to investigate trace elements in patients with rheumatic valvular disease Material and Method A total of 30 consequently (15 male and age: 34.0 ±9.3 years) patients with rheumatic valvular disease and functional capacity class 1 according to NYHA (RVD) who admitted to our cardiology department were enrolled in this sturdy. 30 randomly age/sex matched subjects with no cardiovascular or systemic disease were recruited as control group. Serum levels of trace elements including selenium (Se) zinc (Zn) and iron (Fe) were measured. Results The age and sex were comparable between two groups (p>0.05). Height, weight, serum levels of Fe, Se and Zn were lower in patients with RVD compared to control group (all p values <0.05). In correlation analysis, serum Fe levels were positively correlated with age, weight, and serum Se and Zn levels (all p values <0.05). Serum Se levels were positively correlated with height, serum Fe and Zn levels, while serum Zn levels were positively correlated with height, weight, and serum Fe and Se levels (all p values <0.05). Multivariable regression analyses showed that serum Fe levels were the only independent predictor of RVD (beta value=0,500, p<0.05). Conclusion In this study, we yield that serum levels of Fe, Se and Zn were significantly lower in patients with RVD. These results may be associated with inappropriate immune response in this population. However, it is not clear whether this is a cause or a result of rheumatic heart disease. Additionally, further studies which investigating the effect of replacement of trace elements in rheumatic valvular disease are needed. [ABSTRACT FROM AUTHOR]

Objective: Helicobacter pylori infection can cause disease from mild to severe that may be accompanied by micronutrient deficiencies. We aimed to investigate serum zinc, copper, magnesium and selenium levels in Helicobacter pylori positive children. Materials and Methods: Thirty-four children, with chronic abdominal pain and diagnosed to be Helicobacter pylori-positive and 20 healthy children with the same demo-graphic characteristics were included in the study. Serum zinc, copper and magnesium levels were measured in the flame unit of atomic absorption spectrophotometer, selenium levels were measured in the graphite unit of the same atomic absorption spectrophotometer. Results: Serum zinc levels were significantly higher and serum magnesium levels were significantly lower (p<0.05) in Helicobacter pylori positive children than those of the control group. Although copper levels were lower in patient group than in control group, this difference was not statistically significant (p>0.05). There was no significant difference between serum selenium levels of two groups. Conclusion: We concluded that in Helicobacter pylori-positive children, many trace elements and mineral metabolism may change. [ABSTRACT FROM AUTHOR]

The incidence of neoplasia is increased in end-stage renal disease (ESRD) patients. Zinc (Zn) deficiency is associated with neoplasia and also commonly seen in ESRD patients. However, the data regarding the relationship between Zn levels and tumor markers is scant in this population. We aimed to investigate the relationship between Zn levels and tumor markers in hemodialysis patients. Twenty-six hemodialysis patients (11 male, 15 female, mean age 41.6±14.3 years) and 11 healthy subjects (6 male and 5 female, mean age 38.7±7.2 years) were included. Serum Alpha fetoprotein (AFP), carcinoembriyonic antigen (CEA), CA 19-9, CA 15-5, CA 125, beta subunit of human corionic gonadotrophin (β-HCG) and beta-2 microglobulin (β2M) and Zn levels were measured. Data were analysed by Student's t test. Serum Zinc levels were significantly lower in ESRD patients (group 1) compared to healthy subjects (group 2) (p<0.0001, for all). Serum CEA and β2M levels were also significantly higher in group 1 patients compared to group 2 subjects (p<0.005, p<0.0001, respectively). Serum Ca15-3 and CA-125 levels were found to be significantly lower in group 1 patients compared to group 2 subjects (p<0.005, p<0.001, respectively). There were no statistically significant difference in terms of serum CA 19-9, β-HCG and AFP between group 1 and group 2 patients. In group 1 patients, there was a negative correlation between serum Zn levels and AFP, while a positive correlation was obsorved between serum Zn levels and CA15-3. The measurement of AFP may be beneficial in HD patients. Further studies are needed. [ABSTRACT FROM AUTHOR]
