The effect of zinc deficiency and iron overload on endocrine and exocrine pancreatic function in children with transfusion-dependent thalassemia: a cross-sectional study. BMC Pediatr 2021; 21:468. [PMID: 34686155 PMCID: PMC8532363 DOI: 10.1186/s12887-021-02940-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Accepted: 10/12/2021] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND Children with transfusion-dependent thalassemia (TDT) suffer from secondary hemosiderosis and the delirious effects this iron overload has on their different body organs, including the pancreas. They are also more prone to develop zinc deficiency than the general pediatric population. This study aimed to determine the effect of zinc deficiency and iron overload on the endocrine and exocrine pancreas in TDT children. METHODS Eighty children, already diagnosed with TDT, were included in this study. We assessed the following in the participant children: serum ferritin, serum zinc, endocrine pancreatic function (oral glucose tolerance test (OGTT), fasting insulin level and from them, HOMA-IR was calculated), and exocrine pancreatic function (serum lipase and serum amylase). RESULTS Forty-four TDT children had a subnormal zinc level, while 36 of them had a normal serum zinc level. TDT children with low serum zinc had significantly more impaired endocrine pancreatic function and an abnormally high serum lipase than children with normal serum zinc, p < 0.05 in all. Serum zinc was significantly lower in TDT children with serum ferritin above the ferritin threshold (≥2500 ng/ml) than those below (59.1 ± 20.2 vs. 77.5 ± 28.13), p = 0.02. TDT children, having a serum ferritin ≥2500 ng/ml, had significantly more frequently impaired endocrine pancreatic function and abnormally high serum lipase than TDT children below the ferritin threshold, p < 0.05 in all. CONCLUSION In children with transfusion-dependent thalassemia, zinc deficiency aggravates iron-induced pancreatic exocrine and endocrine dysfunction.

Possible zinc deficiency in the Serbian population: examination of body fluids, whole blood and solid tissues. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2021; 28:47439-47446.

Abstract
Studies indicate that the soil, water and consequently foodstuffs in Serbia are significantly poor in zinc (Zn), and thus, it is likely that there is a Zn deficiency in the Serbian population. This study examined the Zn status in multiple clinical samples, including body fluids (serum, cerebrospinal fluid), whole blood and Zn-rich solid tissues (thyroid and brain tissue). Differences between sex and age were also considered, and comparative analysis of Zn status with other world populations was performed. Serum samples from a large number of Serbian adults approximately had twofold lower Zn amounts when compared to other populations. A similar trend was obtained for whole blood. Males had significantly higher amounts of Zn in serum, whole blood and thyroid tissue samples than females. Higher amounts of Zn were observed in the group older than 50 years. Importantly, in thyroid and brain tissues, Zn was 10- and 20-fold lower, respectively, than reported in the literature. Our results indicate that the population in Serbia could be considered Zn deficient. Therefore, adequate oral Zn supplementation and/or foodstuff fortification should be considered to prevent the deleterious effects caused by Zn deficiency.

Abstract
BACKGROUND Measurements of copper and zinc in transfusion-dependent thalassemia (TDT) show contradictory results. AIM OF THE STUDY To examine serum levels of these minerals in TDT in relation to iron overload indices and erythron variables. METHODS This study recruited 60 children with TDT and 30 healthy controls aged 3-12 years old. RESULTS Zinc was significantly higher in TDT children than in controls, while copper and the copper to zinc ratio were significantly lowered in TDT. Serum zinc was significantly associated with the number of blood transfusions and iron overload variables (including serum iron and TS%) and negatively with erythron variables (including hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin). Serum copper was significantly and negatively associated with the same iron overload and erythron variables. The copper to zinc ratio was significantly correlated with iron, TS%, ferritin, hemoglobin, mean corpuscular volume, and mean corpuscular hemoglobin. Albumin levels were significantly higher in TDT children than in control children. CONCLUSION Our results suggest that the increase in zinc in children with TDT may be explained by iron loading anemia and hemolysis and the consequent shedding of high amounts of intracellular zinc into the plasma. Increased albumin levels and treatment with Desferral may further contribute towards higher zinc levels in TDT. We suggest that the elevations in zinc in TDT are a compensatory mechanism protecting against infection, inflammation, and oxidative stress. Previous proposals for prophylactic use of zinc supplements in TDT may not be warranted.

Abstract
AIM Low levels of immune-related micronutrients have been identified in β-thalassemia samples. Moreover, the excess amount of iron, contributing to oxidative stress in the pathogenesis of the disease, alters the immune system in β-thalassemia, which is important during the COVID-19 pandemic. MATERIALS & METHODS Searches of PUBMED and EMBASE were conducted to identify the level and supplementation of micronutrients in β-thalassemia, published from 2001-May 2020. RESULTS The review found six observational and five interventional studies supporting the importance of supplementing vitamins and minerals among patients with β-thalassemia. CONCLUSION Supplementation of immune-related vitamins and minerals might bring benefits to the immune system, especially in reducing oxidative stress in β-thalassemia.

Abstract
BACKGROUND In parts of Cambodia, irrigation of rice with groundwater results in arsenic accumulation in soils and rice, leading to health concerns associated with rice consumption. In Bangladesh and China, low zinc levels in rice have been found in regions where arsenic levels in rice are high. Furthermore, there have been claims that zinc deficiency is responsible for stunting of children in Cambodia. There are limited data on zinc in Cambodian rice, but in rural Asia, rice is the major source of zinc. OBJECTIVES To provide a preliminary evaluation of the zinc content in rice grain in Preak Russey, an area with elevated levels of arsenic. The importance of zinc in rice for infants was also assessed. METHODS Rice cultivation was evaluated in sixty farms along the Mekong River in Cambodia. Analyses for metals, total arsenic, and arsenic species in the water and rice were conducted at the University of Ottawa, Canada by inductively coupled plasma - mass spectrometry. Analysis of total zinc and arsenic in soils were analyzed in Phnom Penh using X-ray fluorescence spectrometry (XRF). Total zinc in rice was also measured by XRF analysis. RESULTS Rice in the Preak Russey area contained zinc with ½ to ¼ of the 1987 Codex standard for rice in Infant Formula. Moreover, our average zinc concentration in rice samples was less than a third that recommended for zinc fortification in rice by the United Nations World Food Programme. There was a significant (α=0.05) negative correlation between the arsenic and zinc content of rice with the lowest zinc levels occurring near the irrigation wells, the source of arsenic. There was a significantly higher content of zinc in rice from farms that fertilized with cow manure. CONCLUSIONS Handheld XRF spectrometers are useful tools for detection of zinc levels in rice. The potential for zinc deficiency in farmers in areas of Cambodia with arsenic toxicity is high. COMPETING INTERESTS The authors declare no competing financial interests.

Abstract
Beta thalassemia is a common monogenic hereditary hemoglobinopathy which is associated with compound complications. Zinc deficiency, which is commonly observed in thalassemia patients, is also associated with multiple health complications. The objective of this study was to determine the zinc status and its effect on the growth and immune functions of young beta thalassemia major patients. The study included 40 patients in comparison with age- and sex-matched 30 healthy individuals as controls. The patients were interviewed for socio-demographic variables, and their medical histories were obtained from the hospital files. Serum concentrations of zinc and ferritin, height, and body mass indices (BMI) were calculated. Mean serum zinc level in beta thalassemia major patients was 44.7 ± 24.2 μg/dl whereas in the control group it was 63.3 ± 30.3μg/dl. The mean serum zinc level is significantly low in beta thalassemia major patients with respect to the control group. The gender, age, duration of blood transfusion, blood transfusion volume, mean pretransfusion hemoglobin concentration, deferasirox dose, and serum ferritin level bear no relationship with serum zinc level of the beta thalassemia major patients. Zinc level showed no significant correlation with z-scores of stature, sitting height index, BMI, and frequency of recent infections of patients. Although zinc deficiency is common in beta thalassemia major patients, it was found to have no significant effect on physical growth and frequency of infections. Further studies are recommended to investigate zinc status of beta thalassemia major patients.

Abstract
Essential trace elements deficiency including zinc and copper are frequently reported in the literature, but the results are controversial. The aim of this study was to evaluate zinc and copper levels in thalassemia major (TM) patients who were on regular transfusion and iron chelation therapy. In a case-control cross-sectional study 43 TM patients and 43 age-matched and sex-matched healthy controls were examined. Patients were selected by convenience sampling method from TM patients who were registered in Thalassemia Clinic during 6 months. Serum zinc and copper levels were evaluated in all subjects. Zinc and copper dietary intake were also assessed. The median zinc level in the participants was significantly lower than the control group (35 [6.3 to 298] vs. 173 [3.1 to 584] μg/dL; P<0.05), but the mean copper level was significantly higher in the patients in comparison with the control group (260±118 vs. 201±69 μg/dL; P<0.05). In contrast, the mean zinc and copper dietary intake in the patient's group were significantly lower than the control group. The mean serum zinc and copper levels in the patient's group were not different according to iron chelation therapy type. Also, zinc and copper levels in the patient's group were not statistically significant based on ferritin level, age, and duration of therapy. Essential trace elements level change and deficiency might occur in TM patients. Hence, routine assessment of these elements is recommended for better management.

Abstract
OBJECTIVES The aim of this study was to determine the anthropometric measurements in transfusion-dependent β-thalassemia children in Pakistan. The secondary aim was to correlate serum ferritin with the physical growth. METHODS We enrolled 367 children (aged 5-17 years) with transfusion-dependent beta-thalassemia major in the study. Anthropometric measurements, serum ferritin levels, and pre-transfusion hemoglobin levels were measured. Serum ferritin was correlated with the height z-score for age. RESULTS Laboratory evaluation showed that patients had significantly low mean pre-transfusion hemoglobin of 7.66 ± 1.34 g/dl (range 2.5-10.5) and high median (Q3-Q1) serum ferritin of 5012 ng/ml (6829-3532). The median (Q3-Q1) height-for-age z-score of children was low at -2.69 and (-1.46 to -3.80) and 65.4% children had stunted growth (height for age z-score <-2). There was a significant negative correlation between height for age z-score and serum ferritin levels (p < 0.000). Stunting of growth began early during 5-10 years of age but increased markedly with the progress of time. CONCLUSIONS The study showed that children with beta thalassemia major had delayed physical growth possibly secondary to iron overload. Effective and early iron chelation is needed for preventing growth failure in transfusion-dependent beta thalassemia.

Abstract
Background Thalassemia is a common hereditary anemia in humans, and beta thalassemia represents a group of recessively inherited hemoglobin disorders first described by Cooley and Lee and characterized by the abnormal synthesis of β-globin chain. The homozygous state results in severe anemia, which needs regular blood transfusion. Although such treatments increase the patient's life span, a variety of complications, including endocrine, metabolic, skeletal, and growth disorders are being observed due to increased iron storage in the body. Objective There are some reports emphasizing the role of zinc deficiency and its associated outcomes among thalassemia patients, but none from this part of the world. The aim of this study was to determine the serum zinc levels in children with beta thalassemia major. Methods This is a prospective case-control study, which included 35 children between the ages five and 15 years, who were diagnosed as suffering from beta thalassemia major. An equal number of age matched healthy subjects were recruited as controls. The study was carried out at the thalassemia center attached to the Prathima Institute of Medical Sciences (PIMS), Karimnagar, Telangana, India, during the year 2016. Blood samples were collected from both the cases and control subjects and serum zinc activities were analyzed using a semi-automated analyzer. Statistical Package for the Social Sciences (SPSS, Version 15.0) (SPSS Inc., Chicago, USA) was used to calculate the unpaired and independent Student's t-test (p value) to find the significance of the results. Results The mean concentrations of serum zinc among the cases and the controls were 39.25 ± 13.45 and 85.31 ± 13.53 (p <0.0001), respectively. Among the cases, 26 (65%) thalassemia patients had zinc concentration below 60 μg/dl, confirming hypozincemia. Conclusion This study revealed that hypozincemia was prevalent in beta thalassemia major patients. Further evaluation regarding the role of zinc in the development and progression of thalassemia is recommended.

Abstract
The goal of the present study was to determine the levels of minerals in chronically transfused thalassaemic patients living in Antalya, Turkey and to determine mineral levels in groups using different iron chelators. Three iron chelators deferoxamine, deferiprone and deferasirox have been used to remove iron from patients' tissues. There were contradictory results in the literature about minerals including selenium, zinc, copper, and magnesium in thalassaemia major patients. Blood samples from the 60 thalassaemia major patients (the deferoxamine group, n = 19; the deferiprone group, n = 20 and the deferasirox group, n = 21) and the controls (n = 20) were collected. Levels of selenium, zinc, copper, magnesium, and iron were measured, and all of them except iron showed no significant difference between the controls and the patients regardless of chelator type. Serum copper levels in the deferasirox group were lower than those in the control and deferoxamine groups, and serum magnesium levels in the deferasirox group were higher than those in the control, deferoxamine and deferiprone groups. Iron levels in the patient groups were higher than those in the control group, and iron levels showed a significant correlation with selenium and magnesium levels. Different values of minerals in thalassaemia major patients may be the result of different dietary intake, chelator type, or regional differences in where patients live. That is why minerals may be measured in thalassaemia major patients at intervals, and deficient minerals should be replaced. Being careful about levels of copper and magnesium in thalassaemia major patients using deferasirox seems to be beneficial.

Abstract
Background: Diabetic nephropathy is the most common cause of end stage renal disease (ESRD) in developed countries. Several trace elements were reported to be changed in diabetic nephropathy. Objectives: The aim of this study was to investigate changes in serum levels of zinc, copper and chromium and their association with the incidence of ESRD in patients with diabetes. Patients and Methods: This study was performed on 70 patients with type 2 diabetic nephropathy (macro and micro-albuminuria) and 70 healthy individuals. Samples were collected to survey metals by atomic absorption spectrophotometer. Data was analyzed by SPSS18 using descriptive and inferential analysis methods. Results: Mean ± SD levels of Zn, Cu and Cr were significantly decreased in blood samples of patients compared to healthy subjects (P < 0.01). Also the mean concentrations of Cu, Zn and Cr in drinking water of Sari were lower than the accepted limit. Only in one case, Cu was higher than the accepted limit, which was the possibility of contamination by water supply pipes. Conclusions: Cu, Zn and Cr play a specific role in the pathophysiology of diabetic nephropathy. Meanwhile in these patients, low serum levels of Cu, Zn and Cr were not associated with factors such as drinking water. Possible causes should be sought in other factors like urine, intervention factors in absorption and utilization and individual conditions.
