Zinc Levels

Background In thalassemia patients, reduced zinc absorption results from increased serum iron due to repeated blood transfusions, increased iron absorption due to ineffective erythropoiesis, and competitive inhibition between iron and zinc in binding to transferrin, a means of transporting both types of minerals in the blood. Few studies have been done to examine zinc levels in thalassemia patients and its relationship with ferritin. Objective To compare serum zinc in thalassemia patients and healthy controls and to assess for a possible correlation between serum ferritin and zinc in thalassemia patients. Methods This cross-sectional study in 68 subjects was done from October 2016 to August 2017. Serum ferritin measured by chemiluminescence immunoassay and serum zinc by inductively coupled plasma mass  spectrometry (ICP-MS). Wilcoxon test was used to analyze for differences between serum zinc in thalassemia patients and controls. Spearman’s correlation test was used to analyze for a possible correlation between ferritin and serum zinc in thalassemia patients. Results There were 34 patients with thalassemia and 34 healthy control subjects. The median serum zinc was 119.34 µg/dL (IQR=71.27) in the thalassemia group and 120.08 µg/dL (IQR=26.28) in the control group (P=0.36). There was no significant correlation between serum ferritin and zinc in thalassemic children (r=-0.023; P=0.895). Conclusion There is no significant difference in serum zinc levels between thalassemic children and healthy controls. There is  no significant correlation between serum ferritin and zinc in thalassemic children.

Background: This study aims to determine and compare the levels of trace elements copper, zinc, selenium and chromium in GCF and serum of patients with periodontitis and healthy individuals. Methods: This cross sectional study includes 24 study subjects recruited from the patients reporting to the Department of Periodontics , Tagore Dental College Chennai. All the selected patients were subjected to a clinical examination done by a single examiner. The estimation of trace elements Copper, Zinc, Selenium and Chromium in GCF and serum is performed using Perkin Elmer optima 5300 Inductively Coupled Plasma Emission Spectrometer (ICPOES). Results: GCF and serum copper levels showed no significant difference in both periodontitis and healthy groups . Selenium levels tend to be the same in both groups. Serum zinc levels are more in periodontitis patients than healthy subjects (p less than 0.01). GCF chromium levels are found to be more in patients with periodontitis than healthy. Conclusions : More research is therefore needed to monitor the role of these trace elements C with an increased sample size to ascertain whether they are associated with a reduced risk of periodontitis.

Iron chelation therapy with deferoxamine (DFO),the current standard for the treatment of iron overload in patients with betathalassemia,requires regular subcutaneous or intravenous infusions. This can lead to reduced quality of life and poor adherence,resulting in increased morbidity and mortality in iron-overloaded patients with beta-thalassemia. Deferasirox (DFX) is an orally administered iron chelator that has been approved for use in many countries. The requirement of an effective,well tolerated iron chelator with a less demanding mode of administration has led to the development of deferasirox. The present study was aimed to compare the satisfaction and compliance with deferoxamine versus deferasirox (Exjade®),a novel oral iron chelator in patients with transfusion - dependent beta- thalassemia. A cross-sectional,single-center investigation study was carried out in the Thalassemia Center of Ibn-Atheer Teaching Hospital in Nineveh province,Iraq. One hundred and eight thalassemic patients aged between 2- 20 years old having received multiple blood transfusions and a serum ferritin greater than 1500 ng/ml. Patients were randomised into two groups. Group 1 received deferoxamine at a dose of 20-50mg/kg/day and group 2 received deferasirox at the dose of 10-30 mg/kg/day. Another 56 apparently healthy volunteers were used as a control group. The assessment of chelation was done during the period between November 2013 and February 2014 by measurement of serum ferritin. Satisfaction and compliance was assessed by using a special questionnaire prepared by the researcher. Out of the 108 thalassemic patients enrolled there was no discontinuation in treatment with the two drugs under study. The serum ferritin did not change significantly in any of the chelation groups. In comparison with the patients who were treated with DFO,those receiving DFX reported a significantly higher rate of compliance and satisfaction (P < 0.05). However,no significant difference was observed between the two groups regarding their satisfaction (P > 0.05).Compliance with deferasirox (50 %) was more than that with deferoxamine (20 %). Satisfaction with deferoxamine was significantly lower than deferasirox (p= 0.00).

Background: Aortic valve sclerosis (AVSc) is defined as the thickening and calcification of aortic valve cusps, in the absence of obstruction of ventricular outflow. AVSc is linked with a clear imbalance in some trace elements. Aims: The objective of this study was to investigate the relationship between AVSc and serum levels of iron (Fe), zinc (Zn), selenium (Se), and copper (Cu). Additionally, this research aimed to explore the clinical significance of human serum zinc, selenium, copper, and iron concentrations as a potential new biomarker for AVSc patients and to clarify the pathophysiological role in individuals at risk of developing AVSc. Patients and methods: The study included 40 subjects with AVSc (25% male and 75% female) who were compared with a healthy control group with the same gender ratio. AVSc was based on comprehensive echocardiographic assessments. Blood samples were taken and Zn and Cu concentrations were determined through the use of atomic absorption spectroscopy. Se was measured using an inductively coupled plasma mass spectrometry device and Fe was measured using a Beckman Coulter instrument. Results: There was a significant difference in the prevalence of diabetes, blood pressure levels, and body mass index between the patients and the healthy subjects ( p < 0.05). The differences between the serum Fe, Se, and Cu levels of the AVSc patients and the healthy subjects ( p > 0.05) were recorded. The serum Zn of AVSc patients when compared was significantly lower compared with that of the control group ( p < 0.01). Conclusion: Patients with AVSc had an imbalance in some of the trace elements in their blood. The patient group’s valves had higher serum Cu levels and lower serum Se, Zn, and Fe concentrations compared with the healthy group’s valves. In the valve patients as compared, AVSc had a high prevalence of obesity, hypertension, and diabetes.

Objective: Olfactory dysfunction is relatively high in coronavirus disease 2019 (COVID-19) patients. The aim of this study is to investigate the incidence of olfactory disorder objectively in patients with laboratory-confirmed COVID-19 infection. Material and Method: The study included 31 healthy controls and 59 COVID-19 patients who were diagnosed and treated in the COVID departments in a tertiary hospital. The patients with corona virus infection were screened by a questionnaire and were classified into 2 groups as either group 2 (patients without self-reported smell loss) or group 3 (patients with self-reported smell loss). Age and gender matched healthy controls who do not have chronic nasal condition or nasal surgery history comprised the control group (group 1). All of the patients and subjects in the control group were tested by the Sniffin’ Sticks test. All of the answers and scores were recorded, and the comparisons were made. Results: The rate of self-reported smell and taste loss in all COVID-19 patients in this study was 52.5% and 42%, respectively. There was a significant difference in threshold, discrimination, identification, and Threshold, Discrimination, Identification (TDI) scores between groups 1 and 2. When the comparisons between group 1 and 3 were made, again threshold, discrimination, identification, and TDI scores were significantly different. The comparison between groups 2 and 3 demonstrated a significant difference in discrimination, identification, and TDI scores, but threshold score was not different statistically. With questionnaire, the rate of olfactory dysfunction in COVID-19 patients was 52.5%, but with objective test, the rate was calculated as 83%. Conclusion: Olfactory and gustatory dysfunctions are common in COVID-19 patients. According to findings with the objective test method in this study, smell disorder in COVID-19 patients was much higher than those detected by questionnaires.

Advanced analytical methods play an important role in quantifying serum disease biomarkers. The problem of separating thousands of proteins can be reduced by analyzing for a ‘sub-proteome’, such as the ‘metalloproteome’, defined as all proteins that contain bound metals. We employed size exclusion chromatography (SEC) coupled to an inductively coupled plasma atomic emission spectrometer (ICP-AES) to analyze plasma from multiple sclerosis (MS) participants (n = 21), acute ischemic stroke (AIS) participants (n = 17) and healthy controls (n = 21) for Fe, Cu and Zn-metalloproteins. Using ANOVA analysis to compare the mean peak areas among the groups revealed no statistically significant differences for ceruloplasmin (p = 0.31), α2macroglobulin (p = 0.51) and transferrin (p = 0.31). However, a statistically significant difference was observed for the haptoglobin-hemoglobin (Hp-Hb) complex (p = 0.04), being driven by the difference between the control group and AIS (p = 0.012), but not with the MS group (p = 0.13), based on Dunnes test. A linear regression model for Hp-Hb complex with the groups now adjusted for age found no statistically significant differences between the groups (p = 0.95), but was suggestive for age (p = 0.057). To measure the strength of association between the Hp-Hb complex and age without possible modifications due to disease, we calculated the Spearman rank correlation in the healthy controls. The latter revealed a positive association (r = 0.39, 95% Confidence Interval = (-0.05, 0.83), which suggests that either the removal of Hp-Hb complexes from the blood circulation slows with age or that the release of Hb from red blood cells increases with age. We also observed that the Fe-peak corresponding to the Hp-Hb complex eluted ~100 s later in ~14% of all study samples, which was not correlated with age or disease diagnosis, but is consistent with the presence of the smaller Hp (1–1) isoform in 15% of the population.

Background: Febrile seizures are the most common form of convulsion in children with the aged between 6 months to 6 years. Different studies have shown that reduction of zinc leads to the incidence of febrile seizures in children. This study was conducted with the goal of examination of the zinc level in the patients with Febrile Seizures.Methods: This cross sectional study was conducted on 50 children in two equal groups of children with febrile seizures, febrile children without seizures. In order to examine the zinc level blood samples were taken of all subjects and the zinc level of these patients was determined. The data was analyzed using the SPSS-16 statistical software and by descriptive statistical tests.Results: 31 males (47.2%) and 19 female children (52.8%) with the average age of 27.23±15.3 months were examined. The two groups had no significant difference in terms of age and sex. The average of zinc level in the patients with Febrile Seizures was 57.4 µg/dL and it was 116 µg/dL in the febrile children without FS there was a significant difference between the two groups in terms of the zinc level (P=0.01).Conclusions: The low serum zinc level in the group of patients with Febrile Seizures compared with children without febrile seizures indicate the existence of a relationship between the serum zinc level and development of FS in children aged between 6 months and 6 years.

Background and aims: Gamma radiation is widely being used in medical-imaging centers. The aim of this study was to measure possible alterations in serum zinc and selenium levels among nuclear medicine staff. Methods: This cross-sectional study was carried out on 30 nuclear medicine staff as well as on 10 individuals as the control group. Blood samples (20 mL) were obtained from the participants and the serum specimens were isolated by centrifugation at 4000 rpm for 7 minutes. The samples were then used for measurement of zinc and selenium levels. Zinc and selenium levels were measured using atomic absorption spectroscopy (AAS) with a graphite furnace. The mean serum levels of zinc and selenium were compared using SPSS. Results: The mean level of zinc in the radiated group (70.91±14.46 μmol/L) was significantly lower than that in the control group (89.75±17.35 μmol/L) (P=0.002). A negative significant correlation was found between the duration of exposure to radiation and zinc levels (P=0.005). Furthermore, a negative significant relationship was observed between the mean radiation dose after 5 years and zinc concentration (P=0.019). Non-significant difference was found in the mean level of selenium between control (1.71±0.35 μmol/L) and radiation (2.13±1.12 μmol/L) groups. Furthermore, no significant correlation was found between selenium level and exposure time. Conclusion: Based on the results, declined level of zinc can be considered as one of the possible mechanisms caused by gamma radiation on cells which may be associated with oxidative damage. Therefore, zinc therapy can be helpful for those who work at medical radiation centers; however, it merits further studies.

AbstractIntroduction:We aimed to investigate the impact of serum zinc, and vitamin D levels on the development of asthma, and its clinical characteristics.Methods:In our cross-sectional study; 50 patients who were diagnosed as atopic asthma and 70 healthy children consisted the control group. In both groups levels of vitamin D, and zinc were analyzed.Results:A statistically significant intergroup difference was not detected as for age, gender, body height (percentile), and weight (percentile) of the patients (p>0.05). Mean vitamin D levels in the asthmatic patient, and control groups were 32.61±9.48 nmol/L, and 42.55±15.42 nmol/L, respectively. Between two groups a statistically significant difference was found (p=0.001). Zinc levels were higher in the control group without any statistically significant difference between groups (p=0.25). A statistically significant negative correlation (−0.635) was found between vitamin D levels, and severity of asthma in the patient group. As the level of vitamin D increased, a decrease in severity of asthma was seen (p=0.04).Conclusion:Though larger series are needed to arrive at definitive conclusions, we think that vitamin D deficiency rather than zinc deficiency, might convey importance in the emergence, and exacerbation of asthma.

Abstract Background : people with Cystic Fibrosis (CF) have progressive limitation to physical exercise and reduced daily living activities. Regular physical activity (PA) and exercise contribute to the quality of live of people with CF. The objective of this study was to evaluate level of PA , lung function and functional capacity in children and adolescents diagnosed with CF and compare them with those of healthy children and adolescents. Methodology: the study had a cross-sectional design with a control group. Patients with CF were followed at the Children’s Pneumology Outpatient Clinic, and were matched for age and sex with healthy controls from a local public school. The evaluations included daily step count, the shuttle walk test and spirometry. Results: 70 children and adolescents were evaluated, 35 diagnosed with CF and 35 healthy controls. The overall mean age was 11.6±2.9 years. There was no significant difference in level of PA between the patient and control groups. Gender analysis revealed no significant difference in level of PA between the groups or within the CF group. The CF group values were significantly lower than the control group for BMI (p=0.04), percentage of predicted FEV 1 and FEV 1 Z-score (p=0.02 and p=0.010). Conclusion: In this sample, children and adolescents with CF had the same level of PA as their healthy peers. Boys and girls with CF had similar level of PA when stratified by sex, as well as when compared to healthy peers of the same gender. Differences were observed between BMI, FEV 1 and some functional capacity test variables between the groups.
