1.  Serum Selenium, Zinc, and Copper in Early Diagnosed Patients with Pemphigus Vulgaris 
Iranian Journal of Public Health  2012;41(5):105-109.
Pemphigus vulgaris is a life threatening, blistering skin disease. It is an autoimmune abnormality. Due to involvement of oral cavity and pharynx, patients are at risk of nutrients deficiency. The aim of this study was to evaluate the status of selenium, copper, and zinc in these patients.
In a case-control study, 43 newly diagnosed pemphigus vulgaris patients were compared with 58 healthy people from 2009 to 2010. The severity of the disease was estimated according to Harman’s scores. Serum selenium was measured with atomic absorption but serum zinc and copper concentrations were determined spectrophotometrically. Data were compared with independent t test. Correlations were evaluated by Pearson correlation test.
Both groups were the same based on sex, age, and weight and body mass index. The mean duration of disease was 5.6 month. The oral and skin severities were 1.79 and 2.3 respectively, based on Harman’s scores. Serum selenium of pemphigus patients was significantly less than that of healthy people (P<0.001). Serum copper was negatively correlated with duration of disease in males (P=0.02, r=−0.5).
Pemphigus vulgaris negatively affects on serum selenium, copper and zinc. It seems that serum selenium, copper and zinc decrease as the disease lasts longer.

2.  Serum Zinc Levels in Children and Adolescents with Type-1 Diabetes Mellitus 
There have been very few studies, with contradictory results, on the zinc status of children and adolescents with type-1 diabetes mellitus. The objective of this cross-sectional study was to determine zinc status based on the serum zinc concentration in type-1 diabetic children and adolescents and compare it with that of healthy controls.
Thirty children and adolescents with type-1 diabetes mellitus, aged 6 to 18 years, and 30 age- and sex-matched healthy controls participated in the study. Serum zinc, fasting blood sugar, hemoglobin A1c and serum albumin were measured by flame atomic absorption spectrophotometry, enzymatic colorimetry, ion-exchange chromatography and colorimetry using bromocresol green methods, respectively.
No statistically significant difference was found in the mean serum zinc concentration between diabetic patients and healthy controls (111.0 ± 3.1 and 107.1 ± 3.8 mg/dl respectively, P= 0.4). No correlations were found between the serum zinc levels and fasting blood sugar, hemoglobin A1c, or the duration of the disease in the patients.
The zinc levels of diabetic children and adolescents are not noticeably different compared to those of healthy controls and are independent of glycemic control and the duration of the disease.

3.  Beta-Carotene, Vitamin E, MDA, Glutathione Reductase and Arylesterase Activity Levels in Patients with Active Rheumatoid Arthritis 
Iranian Journal of Public Health  2011;40(2):102-109.
Many studies have investigated the possible role of reactive oxygen species in the etiology and pathogenesis of Rheumatoid Arthritis (RA). The aim of this study was to investigate the activities of some antioxidants in RA patients.
In this case-control study, 59 RA patients and 60 healthy sex and age-matched controls were selected. Vitamin E and Beta-carotene were determined using HPLC. Erythrocytes glutathione reductase (GR) activity was measured spectrophotometrically, and malondialdehyde (MDA) was determined by colorimetric method. Arylesterase activity (AEA) was measured by Phenylacetate. The clinical data were determined by a rheumatologist, medical history and filling the questionnaire by interview. Statistical analyses were carried out using the SPSS software.
In patients with RA, serum MDA level was significantly higher and plasma concentration of vitamin E, Beta-carotene and GR activity, were significantly lower than healthy control (P< 0.001). AEA activity differences between two groups were non-significant.
Oxidative stress may play an important role in the inflammation and pathogenesis of RA.

4.  The Effects of Vitamins E and D Supplementation on Erythrocyte Superoxide Dismutase and Catalase in Atopic Dermatitis 
Atopic dermatitis is a public health problem worldwide. Increment of reactive oxygen species (ROS) production may be one of the contributing factors of tissue damage in atopic dermatitis. The present study was designed to determine the effect of vitamins E and/or D on erythrocyte superoxide dismutase and catalase activities in patients with atopic dermatitis.
In a randomized, double blind, placebo controlled clinical trial 45 atopic dermatitis patients were divided into four groups. Each group received one of the following supplements for 60 days: group A (n=11) vitamins E and D placebos; group B (n= 12) 1600 international unit (IU) vitamin D3 plus vitamin E placebo; group C (n=11) 600 IU synthetic all-rac-α tocopherol plus vitamin D placebo; group D (n=11) 1600 IU vitamin D3 plus 600 IU synthetic all-rac-α tocopherol. Erythrocyte superoxide dismutase (SOD) and catalase activities, serum 25 (OH) D, plasma α-tocopherol were determined. The data were analyzed by analysis of variance (ANOVA) and paired t-test.
After 60 days vitamin D and E supplementation, erythrocyte SOD activities increased in groups B, C and D (P= 0.002, P= 0.016 and P= 0.015, respectively). Erythrocyte catalase activities increased in groups B and D (P= 0.026 and P= 0.004, respectively). The increment of erythrocyte catalase activity was not significant in group C. There was a positive significant correlation between SOD activity and serum 25 (OH) D (r= 0.378, P= 0.01).
It is concluded that vitamin D is as potent as vitamin E in increasing the activities of erythrocyte SOD and catalase in atopic dermatitis patients.
