Association between the levels of serum vitamin D and trace elements and joint health in children with hemophilia

Hemophilia is defined as X-linked recessive bleeding disorder. Recurrent bleeding episodes lead to hemarthrosis.Objectives: to investigate the levels of serum 25(OH) D and trace elements in children with hemophilia A and B and to identify the possible association of these factors with Hemophilia Joint Health Score (HJHS). This case-control study was conducted among children with hemophilia A and B. A total of 48 cases were recruited from the hematology units at the Menoufia University Hospital (n = 36) and Sohag University Hospital (n = 12) from December 2020 to February 2022. Forty healthy controls were matched to cases on age, sex and socioeconomic status. Serum zinc and magnesium levels in the hemophilia patients were significantly lower than in the controls, while serum alkaline phosphatase levels in the cases were significantly higher than in the controls. Informed consent was obtained from all the children's parents and ethical approval was acquired from the ethical committee (ID: 5/2020PEDI38), Faculty of Medicine, Menoufia University. The levels of phosphorus and calcium were the same in two groups. Serum 25(OH) D levels were deficient in 85.4% of the cases and insufficient in 14.6%. None of the hemophilia patients had sufficient levels of serum 25(OH) D. There was no significant correlation between HJHS and the levels of serum trace elements but there was a significant positive correlation between HJHS and annualized bleeding rate and a significant negative correlation between HJHS and serum vitamin D. There was no significant difference regarding the demographic data except for weight and body mass index. The patients had significantly higher weight and body mass index compared to the control group. The levels of serum vitamin D and trace elements were decreased in hemophilia patients, and these low values were associated with the worst joint health.

Therapeutic effect of trace elements on multiple myeloma and mechanisms of cancer process.

In the human body, trace elements and other micronutrients play a vital role in growth, health and immune system function. The trace elements are Iron, Manganese, Copper, Iodine, Zinc, Cobalt, Fluoride, and Selenium. Estimating the serum levels of trace elements in hematologic malignancy patients can determine the severity of the tumor. Multiple myeloma (MM) is a hematopoietic malignancy and is characterized by plasma cell clonal expansion in bone marrow. Despite the advances in treatment methods, myeloma remains largely incurable. In addition to conventional medicine, treatment is moving toward less expensive noninvasive alternatives. One of the alternative treatments is the use of dietary supplements. In this review, we focused on the effect of three trace elements including iron, zinc and selenium on important mechanisms such as the immune system, oxidative and antioxidant factors and cell cycle. Using some trace minerals in combination with approved drugs can increase patients' recovery speed. Trace elements can be used as not only a preventive but also a therapeutic tool, especially in reducing inflammation in hematological cancers such as multiple myeloma. We hope that the prospect of the correct use of trace element supplements in the future could be promising for the treatment of diseases.

Co-delivery of streptomycin and hydroxychloroquine by labeled solid lipid nanoparticles to treat brucellosis: an animal study

Can brucellosis-related biochemical and immunological parameters be used as diagnostic and treatment indicators? The goal of this project was to look at biochemical parameters, trace elements, and inflammatory factors in the acute and chronic stages of brucellosis after treatment with streptomycin and hydroxychloroquine-loaded solid lipid nanoparticles (STR-HCQ-SLN). The double emulsion method was used for the synthesis of nanoparticles. Serum levels of trace elements, vitamin D, CRP, and biochemical parameters were measured in rats involved in brucellosis. The therapeutic effect of STR-HCQ-SLN was compared with that of free drugs. In both healthy and infected rats, serum concentrations of copper, zinc, iron, magnesium, potassium, and biochemical parameters of the liver were significantly different. By altering the serum levels of the aforementioned factors, treatment with STR-HCQ-SLN had a positive therapeutic effect on chronic brucellosis. Vitamin D levels declined (46.4%) and CRP levels rose (from 7.5 mg to less than 1 mg) throughout the acute and chronic stages of brucellosis. This study showed that by comparing the biochemical parameters and the levels of trace elements in the serum of healthy and diseased mice in the acute and chronic stages of brucellosis, it is possible to get help from other routine methods for diagnosis.

The assessment of serum trace element levels as the diagnostic biomarkers of functional state of broiler chickens.

Elemental analysis is a useful technique for predicting metabolic disorders in broiler chickens. Elemental imbalances are also important for the development of new methods to diagnose the health status of birds that can be implemented on a farm-wide scale. This study aimed to identify elemental markers related to pre-nosological diagnoses of metabolic disorders in broiler chickens. We compared birds given high-protein, high-carbohydrate, and high-fat diets. A control group received the standard diet recommended by the All-Russian Research and Technological Institute of Poultry, while experimental Group I received a diet with high-protein content, Group II received a diet with high-carbohydrate content, and Group III received a diet with high-fat content. At the end of the experiment, blood samples were taken for biochemical and elemental analysis. Biochemical analysis was carried out using an automated biochemical analyzer, and the levels of trace elements in the serum were assessed using inductively coupled plasma spectrometry. We found that the high-protein diet was accompanied by a decrease in chicken body weight, cholesterol, and several elements (i.e., P, Cr, Cu, Zn, and B) as well as an increase in the levels of Ca, Co, and Si. The high-carbohydrate diet led to a significant increase in glucose levels as well as a decrease in the levels of albumin, triglycerides, and Cr, Mn, Se, I, and Cu. Finally, the high-fat diet led to an increase in body weight, glucose, cholesterol, triglycerides, and the elements Cu, Zn, and Si as well as a decrease in the levels of Mg, Cr, and Fe. The determination of the levels of trace elements such as Co, Cr, Mn, Fe, and Cu in chicken blood serum may be an important indicator of the state of protein, carbohydrate, and lipid metabolism of poultry stock.

The association between maternal iron, zinc, copper levels in serum and pregnancy outcomes.

To investigate the associations of serum trace elements (iron, zinc, and copper) between women with different pregnancy outcomes. About 774 pregnant women who came to The Fourth Hospital of Shijiazhuang for prenatal examination were investigated. The concentrations of trace elements in the serum of pregnant women in the third trimester were collected. Multivariate logistic regression was used to analyze the relationship between serum trace element levels and the different pregnancy outcomes. Multiple linear regression was used to analyze the relationship between serum trace elements levels and hypersensitive-C-reactive-protein. Results of the multiple logistic regression showed that zinc, copper and copper/zinc ratio were found to be associated with the risk of gestational diabetes mellitus, and zinc was a protective factor (p = 0.002) while copper and copper/zinc ratio as risk factors (p = 0.030 and p = 0.001, respectively) after adjusting for major confounders. It was found that iron and zinc were negatively associated with the risk of moderate or severe anemia (p = 0.022 and p = 0.001, respectively). In contrast, the copper/zinc ratio was positively related to the risk of moderate or severe anemia (p = 0.021). The adjusted relationships between copper and copper/zinc ratio with premature rupture of membranes were statistically significant (p = 0.007 and p = 0.037). Iron and zinc were negatively associated with the risk of chorioamnionitis, while copper and copper/zinc ratio were positively associated with the risk of chorioamnionitis (all p < 0.05). Serum iron, zinc and copper levels are closely related to pregnancy outcomes.

Determination of Serum Trace Elements and Oxidative Stress in Bitches with Transmissible Venereal Tumor

Background: This study was conducted to compare the changes in oxidative stress levels with some trace elements in blood serum in healthy bitches and bitches with transmissible venereal tumor (TVT). Methods: A total of 40 bitches were used in the study. According to the genital organ examinations, healthy bitches constituted the control group (n=20) and those with venereal tumors constituted the TVT group (n=20). Total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) were determined spectrophotometrically. In addition, some serum trace element levels such as magnesium (Mg), manganese (Mn), iron (Fe), copper (Cu), zinc (Zn) and selenium (Se) were measured using an ICP-MS analysis device. Result: The serum Se, Mg and Zn levels were lower in the TVT group compared to the control group (p less than 0.01) and serum Fe and Cu levels were higher in the TVT group than in the control group (p less than 0.01). Serum TOS and OSI levels were higher (p less than 0.001) and serum TAS levels were lower (p less than 0.001) in the TVT group compared to the control group. The study results showed that oxidative stress is high in bitches with TVT, and in parallel with this, changes occur in the amount of certain trace elements that are associated with oxidative stress.

The effect of pimobendan and enalapril use on blood serum trace element levels in dogs with myxomatous mitral valve disease

Background and objectiveMyxamatous mitral valve disease (MMVD) is a common acquired heart disease in dogs that can lead to progressive and long-term congestive heart failure (CHF). Pimobendan and angiotensin converting enzyme inhibitors (ACEI) are commonly used in MMVD treatment. Trace elements are essential for maintaining cardiovascular functions. Synergistic or antagonistic interactions between some trace elements and substances are widely known. In our study, it was aimed to evaluate the effects of treatment duration, age, weight and gender on serum trace element levels in dogs with MMVD by using pimobendan and enalapril as monotherapy. Material-Methods13 dogs with MMVD were treated with pimobendan (0.25–0.3 mg/kg, q12h, PO Vetmedin®) and 21 dogs with MMVD were treated with enalapril (0.25–0.5 mg/kg, q12h, PO Enapril®) for at least 30 days. The serum trace element levels (Cu, Zn, Fe, Co, Mg, Mn, Se, Cr) of all patients were measured with Inductively coupled plasma-Optical emission spectroscopy device. Relevances were evaluated related to treatment duration, age, weight and gender in each treatment group. ResultsAdjusted R2 values of the model, which included treatment, treatment duration, treatment x duration interaction, age, weight and gender as predictors, were negative except for Se. Furthermore, the model explained only 10.4% of the variation in Se. The effect of age was significant in the model of Se (β = 0.462; P = 0.028). Treatment duration also tended to be significant in the prediction of Se concentration (β = -0.364; P = 0.086). ConclusionWe consider that treatment (enalapril vs. pimobendan), treatment duration, treatment x duration interaction, weight and gender were not good predictors of trace elements. In our study, age contributed significantly only to the Se level.

An evaluation of trace elements and oxidative stress in patients with benign paroxysmal positional vertigo.

Vertigo and Dizziness are a common complaint among the reasons for applying to the ear nose throat clinic. Benign Paroxysmal Positional Vertigo (BPPV) is the most common cause of perpheric vertigo. Oxidative stress is caused by the formation of hydroxyl radicals, superoxide anions and hydrogen peroxide, which are reactive oxygen derivatives (ROS). The aim of this study is to investigate the relationship between complaints and serum trace element and oxidative stress levels in patients with BPPV. This study was conducted with 66 adult patients who presented to the ENT policlinic with the complaint of vertigo and were diagnosed with BPPV between May 2020 and September 2020. Blood samples were taken from patients diagnosed with BPPV to measure serum Zn and Cu levels and oxidative stress levels during an attack. The mean ages of the study patients and healthy controls were 45.7 ± 15.1 and 44.7±13.2. Female / Male ratio were 28(42.5%)/38(57.5%) and 32(48.5%)/34(51.5%) in study and control group. We found serum Cu levels were lower in the patient group (p <0.05). Serum Total Thiol and Native Thiol values were lower in patients with BPPV. Total Thiol results were statistically significant.(p<0.05) Disulfide values were significantly higher in the disease group. (P <0.05). Thiol Oxidized / Thiol Reduced ratio (2243.6±6.7/343.8±125.3) was higher in control group. (p<0.05). Serum oxidative stress and trace elements play a role in the pathophysiology of BPPV. We present the cut-off values for Cu and Zn in vertigo patients for the first time in the literature. We think that these cut-off values of the trace elements and thiol/disulfide hemostasis can be used clinically by physicians in the etiology, diagnosis and treatment of vertigo.

Analysis of serum calcium, sodium, potassium, zinc, and iron in patients with pre-eclampsia in Bangladesh: A case-control study.

Pre-eclampsia is a particular type of pregnancy condition. Although the primary etiology of pre-eclampsia is unclear, it hypothesizes that the alteration of trace elements and macro-minerals may play a crucial function in the pathogenesis of Pre-eclampsia. Therefore, our research sought to ascertain the serum level of trace elements (zinc, iron) and macro-minerals (sodium, calcium, potassium) and their possible association with pre-eclampsia. The present study was conducted with 74 pre-eclampsia pregnant women (case) and 118 pregnant women having normal blood pressure (controls). Atomic Absorption Spectroscopy determined the serum level of trace components and electrolytes. The researchers discovered notable differences in maternal age, gestational period, body mass index, systolic and diastolic blood pressure, hemoglobin, and creatinine level. Results of serum analysis revealed that calcium (52.06 ± 3.71 mg/L vs. 65.93 ± 2.57 mg/L, p < 0.05) and potassium (63.44 ± 5.33 mg/L vs. 102.54 ± 4.25 mg/L, p < 0.001) concentrations were substantially lower in the patient group than in control. Serum zinc (0.34 ± 0.02 mg/L vs. 0.52 ± 0.02 mg/L, p < 0.001) and iron (0.38 ± 0.03 mg/L vs. 0.46 ± 0.02 mg/L, p < 0.05) concentration were also considerably decreased in pre-eclampsia participants compared with a pregnant normotensive group. Pearson's correlation research results in the patient group revealed a connection between trace elements or macro minerals. In addition, the systolic blood pressure was positively correlated with sodium (r = 0.392, p < 0.01) and negatively correlated with potassium (r = -0.257, p < 0.05) in the control group. This study concludes that calcium, potassium, iron, and zinc levels were lower, whereas sodium levels were higher in Bangladeshi pre-eclampsia patients compared to controls. These findings with Pearson's correlation and the inter-element relationship between the patient and a control subject results can act as critical indication factors for patients with pre-eclampsia in Bangladesh and, as a result, may require a higher intake of calcium, potassium, iron, and zinc for effective therapeutic intervention and reduce the intake of sodium.

The Contributions of Trace Elements on Molecular Subtype-Specific Colorectal Cancer.

Purpose: Although growing studies have reported the disturbances of trace elements (TEs) homeostasis was closely associated with the occurrence of colorectal cancer (CRC), the clinical value of TEs in CRC with different molecular subtypes was largely unknown. This study aimed to explore the correlation between KRAS mutations/MSI status and serum TEs levels in patients with CRC. Methods: The serum concentrations of 18 TEs were detected by inductively coupled plasma emission spectrometry (ICP-MS). MSI status (two mononucleotides: BAT25, BAT26, three dinucleotides: D2S123, D5S346, and D17S250), KRAS (G516T, G517A, G518C, G520T, G521A, G522C, and G532A) mutations were detected by the multiplex fluorescent PCR and the real-time fluorescent quantitative PCR, respectively. The correlations among KRAS mutations/MSI status, demographic and clinical characteristics, and TEs were analyzed by Spearman correlation analysis. Results: The propensity score matching (PSM) analysis was adopted to minimize differences between groups. Before PSM, 204 CRC patients were recruited in this study, including 123 KRAS-negative patients and 81 KRAS-positive patients according to the test results of KRAS mutations, and 165 MSS patients and 39 MSI patients based on MSI detection. After PSM, the serum concentration of Mn was significantly lower in CRC patients with KRAS mutations than those without KRAS mutations, and a significant negative correlation was observed between Mn and Pb in the KRAS-positive cases. CRC patients carrying MSI had a significantly lower level of Rb compared to MSS patients. Importantly, Rb was significantly positively correlated with Fe, Mn, Se, and Zn in patients with MSI. Collectively, all our data indicated that the occurrence of different molecular events might be accompanied by different alterations in types and levels of serum TEs. Conclusions: CRC patients with different molecular subtypes presented different alterations in types and levels of serum TEs. Mn was significantly negatively correlated with the KRAS mutations, and Rb was noticeably negatively correlated with the MSI status, indicating certain TEs might contribute to the pathogenesis of molecular subtype-specific colorectal cancer.

Investigation of Serum Trace Element Levels of Nigerian Women at a Late Stage of Pregnancy

Abstract Introduction: Minerals such as selenium, zinc, copper, and manganese often referred to as antioxidant trace elements have been recognized as modulators of oxidative stress-induced conditions. Due to this very crucial function, their constant monitoring during gestation is not only encouraged but desirable. Aim: The study aims to evaluate serum levels of Zn, Cu, Mn, and Se during gestation. Materials and Methods: Forty third-trimester pregnant women (29 weeks to term) attending antenatal clinics at maternity centers within the Osogbo metropolis as well as 40 apparently healthy women, age matched, and nonpregnant that served as controls were participants for the study. Serum obtained from 5 mL of blood was used for the elemental study (inductive computerize plasma emission spectrometry). Data were analyzed using Student’s t-test and Pearson’s correlation coefficient. The level of statistical significance was P &lt; 0.05. Results: Concentrations of serum trace elements (Zn, Mn, and Cu) levels were significantly lower, but selenium was significantly higher in pregnant women compared to the control group. Correlation results revealed a relationship only between copper and manganese. Conclusion: The results of this study showed that Nigerian pregnant women in the Osogbo metropolis are at risk of zinc, copper, and manganese depletions. This suggests that both the fetus and pregnant mother may be susceptible to oxidative stress-induced conditions.

Serum trace element levels in dogs with canine visceral leishmaniasis

Association between serum trace elements and sleep disturbance in patients with decompensated cirrhosis.

Sleep disturbance and trace elements imbalance are common features in patients with decompensated cirrhosis, partially sharing similar mechanistic contributors and linking to adverse outcomes. However, there is a paucity of data concerning their relationship. To investigate the association between serum trace elements levels and sleep quality in the context of cirrhosis. Cross-sectional study. We consecutively enrolled 160 patients with decompensated cirrhosis. The sleep disturbance was determined by the Pittsburgh Sleep Quality Index (PSQI > 5). Serum trace elements [magnesium, calcium, iron, copper (Cu), zinc (Zn), lead, and manganese] was measured by inductively coupled plasma mass spectrometry. Association of examined trace elements levels and sleep disturbance was analyzed by multiple linear (global PSQI scores) and multivariate logistic (dichotomized PSQI categories) regression models, respectively. In total, 91 patients (56.88%) represented PSQI-defined sleep disturbance, characterized by female preponderance, lower body mass index levels, and higher serum Cu levels (all p < 0.05). Looking into its clinical relevance with debilitating conditions, we showed that Cu/Zn ratio (CZr) is significantly higher in cirrhosis with poor sleep quality (1.77 versus 1.48, p = 0.003). Diagnostic performance analysis indicated CZr > 1.62 to exhibit better discrimination relative to respective Cu. Both multiple linear (β = 0.355, p < 0.001) and multivariate logistic regression (odds ratio = 2.364, p = 0.019) identified higher CZr as an independent risk factor associated with sleep disturbance. Our findings implied an association between higher CZr and the presence of sleep disturbance in patients with decompensated cirrhosis.

Correlation of serum trace elements (Fe, Cu, and Zn) in the blood samples of Indian patients with leukoplakia, oral squamous cell carcinoma, and normal subjects.

Trace elements (iron, copper, and zinc), leukoplakia, and oral squamous cell carcinoma. To study and correlate serum trace element (iron, copper, and zinc) levels in leukoplakia, oral squamous cell carcinoma, and normal subjects. The present study comprised a total of 80 patients, which included 30 patients of leukoplakia, 30 patients of oral squamous cell carcinoma, and the normal control group comprising 20 healthy individuals who were not having any relevant medical, dental, and habit history. Peripheral blood samples of a volume of 10 ml each will be collected by anti-cubical vein puncture from control groups and from patients suffering from leukoplakia and oral squamous cell carcinoma. The blood will be collected in a plain red top vein puncture tube without additives or anti-coagulants and allowed to stand undisturbed to clot at room temperature, and serum will be separated from the cells by centrifugation at 4°C at a speed of 3000 rev/min, the separated sera will be kept at -20°C until analysis is performed. The estimation of serum zinc (Zn) and copper (Cu) levels is performed by atomic absorption spectrometry (AAS). In the present study, the estimation of copper and zinc levels was conducted by using an atomic absorption spectrophotometer (model no: AA-6300 SHIMADZU, Japan). Serum iron estimation is performed using the kit RANDOX (siedel, 1984). Statistical analysis is performed by the paired and Scheffe tests. From the results, it was concluded that there was a decrease in serum iron and zinc levels and copper had increased serum levels. It was concluded that evaluation of serum trace elements can be a cost-effective and non-invasive alternative for screening, diagnosis, and monitoring of pre-malignant lesions such as leukoplakia and malignant lesions such as oral squamous cell carcinoma. Thus, these parameters can be used as biomarkers that provide important tools in formulating an adequate diagnosis, treatment plan, and prognosis for oral squamous cell carcinoma.

Associations of trace element levels in paired serum, whole blood, and tissue: an example of esophageal squamous cell carcinoma.

Previous studies have extensively explored impacts of trace elements on human beings and complex relationships with cancers. However, contradictory conclusions may be more challenging to explain due to biological specimen differences. To investigate the distribution of trace elements inside body, we collected serum, whole blood and tissues from 77 patients with esophageal squamous cell carcinoma (ESCC), as well as serum and whole blood from 100 healthy individuals, and determined the concentrations of 13 elements (Al, V, Cr, Mn, Co, Ni, Cu, Zn, As, Se, Sr, Cd, and Pb) with inductively coupled plasma-mass spectrometry (ICP-MS). Al, Ni, Cu, Sr, and Cd variations between patients and controls were found to be inconsistent in serum and blood. Concentrations of Cu, As, Se, and Sr in serum were positively correlated with that in whole blood in both case and control group (rs >0.450, P <0.01). Elements in serum had a higher accuracy (87.0%) than whole blood (74.0%) in classifying ESCC patients and healthy individuals with discriminant analysis. As, Cd, and Pb concentrations in cancerous tissues were positively correlated with those in normal epithelium (rs =0.397, 0.571, and 0.542, respectively), while Mn, Cu, and Se accumulated in malignant tissues, with V, Cr, Co, Ni, Sr, and Cd partitioning in normal epithelium (all P <0.05). Thus, certain elements in blood, such as Cu, As, Se, and Sr, were useful in assessing element exposure burdens and accumulation tendency of some elements (Mn, Cu and Se, etc.) was uncovered in tumors. Our investigation demonstrated the variations in trace element distribution for frequently used specimens and further evidence of etiological mechanism is necessary.

A comparative study of serum zinc levels in male hypertensive and non-hypertensive individuals in Peshawar Khyber Pakhtunkhwa, Pakistan

Background: Numerous studies have shown that serum levels of trace elements including zinc play an essential role in regulation of hypertension. Objective: The objective of current study is to evaluate the differences in serum zinc levels among hypertensive and non-hypertensive male participants from Peshawar Khyber Pakhtun Khwa in Pakistan. Method: The study comprised of 140 adult males (70 hypertensive and 70 non-hypertensive). The subject’s age, weight, heights, and medical histories were acquired with informed consent on a well-designed proforma. Fresh blood samples were taken from 140 male participants in a Gel tube. The lipid profile test assessed total cholesterol, triglycerides, low-density lipoprotein, and high-density lipoprotein. An atomic absorption spectrophotometer with an acetylene flame was used for determination of serum zinc levels under normal conditions (Model Perkin Elmer AAS 700). Results: The mean serum zinc level (0.07115mg/dL) was lower in hypertensive subjects in comparison with non-hypertensive subjects (0.3428mg/dL).Conclusion: The mean serum zinc level in hypertensive subjects was lower than in non-hypertensive subjects.

Association between Iron &amp; Other Trace Elements Deficiency and Febrile Seizure in Children

Introduction: Febrile seizures are the most common type of seizure in children occurring in 2-5 % of them with a peak incidence in 16-18 months. Various factors have been described in the pathophysiology of febrile seizures like susceptibility of the immature brain to temperature, an association between interleukins, circulating toxins, and trace elements deficiency.&#x0D; Aim: To study the association between serum levels of trace elements (Iron, zinc, copper, calcium and magnesium) in children with febrile seizures.&#x0D; Study Design: An observational cross-sectional study.&#x0D; Place and Duration of Study: Department of Pediatrics of PGIMER, Dr RML Hospital, New Delhi between November 2016 and March 2018.&#x0D; Methodology: This study was conducted at a tertiary care centre and enrolled 75 children of which 55 were febrile seizures and 20 patients were controls. The serum specimen was collected with all aseptic techniques, and all due precautions were taken for the blood sample to protect them from sunlight exposure, haemolysis and contamination. Then samples were centrifuged at 3,000 rpm for 5 minutes and were stored at -20 c until the final assay. Serum Iron, Zinc, Copper and Magnesium levels were measured using a fully automated chemistry analyser (AU400). Data was entered in MS Excel spreadsheets and analysed using the statistical package for social science (SPSS) version 21.0. &#x0D; Results: Children with febrile seizures (cases) were found to have significant iron deficiency (higher TIBC, higher UIBC and lower Ferritin) than the controls (P&lt;0.001). There was no significant difference in the serum levels of copper, zinc, magnesium, and ionized calcium in the two groups. There was no difference in serum levels of trace elements in cases with simple or complex febrile seizure.&#x0D; Conclusion: Children with febrile seizures showed significant iron deficiency (higher TIBC, higher UIBC and lower Ferritin) in cases than those with controls. But, there was no significant association between other serum trace elements (zinc, copper, calcium, magnesium) and febrile seizure. However, further large multi-centric trials are required to suggest any association between them.

Investigation of Serum Trace Element Levels in Sheep in Diyarbakır Province and Districts

Background: In this study, the serum of sheep raised on pasture in the province and districts of Diyarbakır was tested for concentrations of the essential trace elements Cr, Cu, Se, Zn, Co, Mn, ultra-trace elements like Ni, V and Ag and non-essential toxic trace elements like Al, Pb, As, Cd and Ti. Methods: The animals used in the study consisted of 313 healthy sheep at the end of lactation obtained from different districts of Diyarbakır. The closed system method of wet decomposition was used to transfer serum trace elements to the soluble phase in blood samples. Serum trace elements were analyzed using an ICP-MS device. Result: This study contributed to obtaining normal levels of Al, Ag, Ni, Ti and V trace elements in ewes at the end of lactation. It was observed that there was no difference between all districts in terms of serum Al, Ni, Cu and Zn trace element levels. In the study, differences were found in the serum Cr, Se, As and Cd trace element levels of sheep between the districts; however, it was determined that no significant deficiency or excess occurred and these levels were within normal limits. The Co and Mn levels we obtained in Diyarbakýr are much lower than the average levels reported by the researchers. We can say that the addition of Co and Mn trace elements in appropriate proportions to the rations of animals can positively affect animal health and productivity.

Trace element levels in serum and gastric mucosa in patients with Helicobacter pylori positive and negative gastritis

BackgroundMost trace elements are inhibited by Helicobacter pylori-infection, and variations in specific element levels are linked to the development of stomach cancer. This is the first study to show the relationship between serum and tissue concentrations of twenty-five trace elements and H. pylori infection status. This study purposed to define serum and tissue trace element levels of 25 healthy individuals with Helicobacter pylori-positive gastritis and Helicobacter pylori-negative gastritis and to reveal their relationship with the disease. MethodsStudy groups consisted of sixty-two patients with Helicobacter pylori-positive, thirty-seven patients with Helicobacter pylori-negative, and thirty healthy individuals. Serum and tissue concentrations of twenty-five elements (aluminum, boron, arsenic, barium, calcium, beryllium, copper, cadmium, iron, chromium, mercury, lithium, potassium, magnesium, sodium, manganese, nickel, phosphorus, lead, scandium, strontium, selenium, tellurium, titanium, zinc) were defined by inductively coupled plasma optical emission spectrometry. ResultsExcept for copper, lithium, and strontium elements in serum samples, other trace elements differed significantly between the groups (p < 0.05). The serum chromium (p = 0.002), mercury (p = 0.001), boron (p < 0.001), and cadmium (p < 0.001) levels of H. pylori-negative gastritis and H. pylori-positive gastritis participants were significantly different, and their serum concentrations were less than 0.5 µ/l. Boron, barium, beryllium, chromium, lithium, phosphorus and strontium elements in tissue samples did not differ significantly between the groups (p > 0.05). Manganese, nickel, tellurium and titanium elements were not detected in tissue and serum samples. The mean concentrations of calcium, beryllium, chromium, iron, potassium, lithium, magnesium, scandium, and selenium were higher in the tissues of patients with H. pylori gastritis compared to healthy control tissues. Also, cadmium could not be detected in tissue samples. There was a significant difference between H. pylori-infected tissue and serum chromium levels (p = 0.001), with lower levels detected in tissue samples. ConclusionThis is the first study that we are knowledgeable of that reports the concentrations of twenty five elements in both serum and tissue samples, as well as the relationship between trace elements and Helicobacter pylori-infection status. Dietary adjustment is indicated as an adjunct to medical therapy to stabilize trace elements because Helicobacter pylori bacteria cause inflammation and impair element absorption in gastritis patients. We also think that this study will shed light on studies on the relationship between Helicobacter pylori-trace elements and serum-tissue/healthy serum-tissue trace element levels of patients with Helicobacter pylori gastritis.
