Abstract
The aim of this study was to systematically evaluate the relation between zinc and the thyroid hormones in humans. The search for articles was conducted using the Pubmed, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL), and ScienceDirect databases on October 21 and 22, 2019, by two authors independently. The recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were followed in the conduct of this review. The Cochrane Collaboration tool was used to assess the risk of bias of the trials included in this review. After the screening of the articles, eight studies that assessed the effects of zinc supplementation on thyroid hormone concentrations and ten studies that assessed the relationship between blood zinc concentrations and thyroid hormones were included in this systematic review. Although cross-sectional and case-control studies have shown a relationship between zinc deficiency and thyroid, the data from this systematic review provides inconclusive evidence with respect to the effects of zinc supplementation on thyroid hormone concentrations due to the divergence of the research found by the authors that only reports findings in patients suffering from some kind of disease, which cannot be generalized to the average human population.

Saghazadeh A, Mahmoudi M, Dehghani Ashkezari A, Oliaie Rezaie N, Rezaei N. Systematic review and meta-analysis shows a specific micronutrient profile in people with Down Syndrome: Lower blood calcium, selenium and zinc, higher red blood cell copper and zinc, and higher salivary calcium and sodium. PLoS One 2017; 12:e0175437. [PMID: 28422987 PMCID: PMC5396920 DOI: 10.1371/journal.pone.0175437] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2016] [Accepted: 03/27/2017] [Indexed: 12/12/2022] Open
Abstract
Different metabolic profiles as well as comorbidities are common in people with Down Syndrome (DS). Therefore it is relevant to know whether micronutrient levels in people with DS are also different. This systematic review was designed to review the literature on micronutrient levels in people with DS compared to age and sex-matched controls without DS. We identified sixty nine studies from January 1967 to April 2016 through main electronic medical databases PubMed, Scopus, and Web of knowledge. We carried out meta-analysis of the data on four essential trace elements (Cu, Fe, Se, and Zn), six minerals (Ca, Cl, K, Mg, Na, and P), and five vitamins (vitamin A, B9, B12, D, and E). People with DS showed lower blood levels of Ca (standard mean difference (SMD) = -0.63; 95% confidence interval (CI): -1.16 to -0.09), Se (SMD = -0.99; 95% CI: -1.55 to -0.43), and Zn (SMD = -1.30; 95% CI: -1.75 to -0.84), while red cell levels of Zn (SMD = 1.88; 95% CI: 0.48 to 3.28) and Cu (SMD = 2.77; 95% CI: 1.96 to 3.57) were higher. They had also higher salivary levels of Ca (SMD = 0.85; 95% CI: 0.38 to 1.33) and Na (SMD = 1.04; 95% CI: 0.39 to 1.69). Our findings that micronutrient levels are different in people with DS raise the question whether these differences are related to the different metabolic profiles, the common comorbidities or merely reflect DS.

Abstract
Radioiodine 131 (131I) has been used worldwide for the ablation of remnant thyroidal tissue after surgery or as the first-line treatment for Graves’ disease. Although the use of 131I is becoming increasingly prevalent, there is evidence suggesting that this treatment is associated with side effects such as salivary gland dysfunction and an increased risk of leukemia. This article aims to review the potential use of radioprotective agents and the side effects induced by 131I therapy. Several synthetic and natural compounds have been investigated in preclinical and clinical studies. The protective agents reduced the toxicity of 131I, mainly in the salivary glands, and mitigated the genetic damage through different mechanisms. There are limited clinical studies evaluating the use of radioprotective agents in patients undergoing radioiodine therapy. However, lemon candies, lemon juice and sugarless chewing gum have been proposed to be beneficial for minimizing the side effects of radioiodine within the salivary glands.

Abstract
Este estudo relata os aspectos funcionais do zinco, bem como a participação desse mineral nas alterações metabólicas presentes em indivíduos portadores de Síndrome de Down. A maioria dos trabalhos realizados observou que o estado nutricional relativo ao zinco nesses pacientes está inadequado, com alterações no sistema antioxidante, imunológico e no metabolismo dos hormônios da tireóide. Estudos in vitro apontam que o zinco participa como cofator da enzima deiodinase tipo II na conversão periférica de Tiroxina em Triiodotironina, e que essa reação está diminuída em indivíduos portadores de Síndrome de Down, o que contribui para a manifestação de distúrbios, como o hipotireoidismo subclínico. As alterações na compartimentalização do zinco no organismo desses indivíduos também favorecem a expressão excessiva da enzima cobre/zinco (Cu/Zn) superóxido dismutase, com aumento do estresse oxidativo, e ainda alterações no sistema imune. Na Síndrome de Down, tem sido demonstrada melhora no metabolismo dos hormônios tireoidianos e na função imune, após a suplementação com zinco. Portanto, o papel metabólico do zinco na Síndrome de Down deve ser mais pesquisado, tendo em vista que esse mineral pode contribuir no controle das alterações metabólicas comumente presentes em indivíduos portadores dessa síndrome.

Abstract
OBJECTIVE AND DESIGN Lowered neonatal plasma thyroxine (T(4)) and mildly elevated thyrotropin concentrations together with developmental benefits from neonatally started T(4) treatment in a randomized clinical trial demonstrated Down syndrome (DS) neonates to be mildly hypothyroid, at least during their first weeks of life. To prove that this hypothyroid state persists beyond this period in all, and to elucidate its etiology, we evaluated the course of the thyroid function determinants in all DS infants participating in this 24-month trial. MAIN OUTCOME Mean plasma thyrotropin concentrations and thyrotropin frequency distributions of 97 placebo-treated infants were persistently shifted to substantially higher concentrations, while free T(4) frequency distributions were in the lower two thirds of the reference interval. Mean thyroglobulin concentrations were normal. To normalize plasma thyrotropin, T(4)-treated DS infants (N = 99) needed rather high free T(4) concentrations, like T(4)- treated non-DS children with thyroidal congenital hypothyroidism. At ages 12 and 24 months, thyroid peroxidase antibodies were detected in 1.1% and 5.4% of all DS infants. CONCLUSIONS These findings suggest that as a group DS infants have a novel type of persistent mild congenital hypothyroidism, presumably of thyroidal origin. The group character suggests a direct relation with the trisomic state of chromosome 21, hypothetically through genomic dosage imbalance of dosage-sensitive genes interfering with thyroid hormone production.

Abstract
Abnormal zinc and lipid plasma levels occur more frequently in metabolically uncontrolled diabetic patients. These lipid alterations are key factors in the emergence of microvascular complications, which lead to death in those patients. Yet, zinc sulfate supplementation may be a therapeutical resource to recover some functioning and improve life span. This article reports the assessment of lipid profile from type 2-diabetes mellitus patients treated with hypoglycemic therapy drugs, who additionally presented zinc levels lower than average in Mexican reference. The patients received a 100 mg zinc sulfate treatment in a crossover double-blind design of clinically controlled study with starch as placebo. The diabetic patients had changes in their lipid profile after a 12-week zinc treatment as compared with placebo treatment. The 100 mg zinc sulfate treatment was well tolerated, significantly reduced total cholesterol and triglyceride concentrations, and increased those corresponding to zinc as well as HDL cholesterol in the bloodstream. Thus, using this treatment the cardiovascular involvement is expected to decrease in the type 2-diabetes mellitus patients, especially those with myocardial infarction and stroke, which are the main death causes in Mexico.

Abstract
Slipped capital femoral epiphysis (SCFE) and Down syndrome are both uncommon in the population at large, and rarely are both conditions present in a single individual. Institutional records were searched for both Down syndrome and SCFE. At least 2 years of follow-up was required. Eight patients were identified. At presentation four patients could not walk due to pain and four could walk. Six of eight hips presented with grade III SCFE. Four hips were treated with internal fixation in situ and four were manipulatively reduced in the operating room at the time of fixation with percutaneous screws or pins. Three hips healed uneventfully. Five hips developed aseptic necrosis (three partial, two whole head). This small retrospective study suggests an extremely high rate of complications in adolescents with Down syndrome and SCFE.

Abstract
Dementia of the Alzheimer type (DAT) is common in older persons with Down syndrome (DS). There are three common alleles of the apolipoprotein E (ApoE) gene (Sigma 2, Sigma 3, and Sigma 4) resulting in three different isoforms (E2, E3, and E4) and six different genotypes (2,2; 2,3; 2,4; 3,3; 3,4; and 4,4). Sigma 4 is a risk factor for DAT whereas Sigma 2 appears prophylactic. As hepatitis B virus (HBV) infection and hypothyroidism also are common in DS, we evaluated associations between ApoE type, HBV status, and thyroid status in a sample of older persons with DS (n = 55; mean age, 44.3 +/- 10.8 years) using chi-squared analysis. Participants were classified as E2 (2,2 or 2,3), E3 (3,3), or E4 (3,4 or 4,4); positive for markers of HBV infection in the present or past (i.e., total HBcAb+ and/or HBsAg+ with or without infectivity, defined as HBV+) or negative for markers of HBV infection (defined as HBV-) and, currently receiving thyroid hormone supplement (defined as "hypothyroidism") or having normal thyroid function. The majority of the HBV+ were currently HBcAb+ and HBsAb+, but not HBsAg+. In females, there was an ApoE allele effect on thyroid status (P < or = 0.01), E2 being negatively (P < or = 0.01) and E4 being positively (P < or = 0.05) associated with "hypothyroidism". There was no evidence for an ApoE allele effect on thyroid status in males. There was no evidence for an ApoE allele effect on HBV status, or for an HBV status effect on thyroid status. As thyroid status can affect cognitive function, ApoE allele effects in DAT may, in part, be thyroid effects.

Abstract
In subjects affected by trisomy 21 (Down syndrome), hypothyroidism is the most common endocrinological deficit. Plasma zinc levels, which are commonly detected below the normal range in Down patients, are related to some endocrinological and immunological functions; in fact, zinc deficiency has been shown to impair immune response and growth rate. Aims of this study were to evaluate (1) the role of zinc deficiency in subclinical hypothyroidism and (2) thyroid function changes in Down children cyclically supplemented with zinc sulfate. Inverse correlations have been observed between age and triiodotironine (T3) and between zinc and thyroid-stimulating hormone (TSH); higher TSH levels have been found in hypozincemic patients at the beginning of the study. After 6 mo of supplementation, an improvement of thyroid function (TSH levels: 3.96 +/- 1.84 vs 2.64 +/- 1.33 mUI/mL basally and after 6 mo, respectively) was observed in hypozincemic patients. In the second cycle of supplementation, a similar trend of TSH was observed. At the end of the study, TSH significantly decreased in treated hypozincemic subjects (4.48 +/- 1.93 vs 2.96 +/- 1.20 mUI/mL) and it was no longer different in comparison to normozincemic patients. We suggest zinc supplementation to the diet in hypozincemic Down children as a simple and useful therapeutic tool.

Abstract
Periodontal conditions and salivary levels of immunoglobulins sIgA, IgM, and IgG subclass distribution and albumin, quantified by enzyme-linked immunosorbent assay, were determined in 20 patients with Down syndrome and 19 healthy controls. Gingival inflammation was more extensive (P < 0.05) among Down syndrome subjects compared to controls as well as the occurrence of periodontal pockets (> 4 mm) (P < 0.05). The immunoglobulin levels of sIgA, IgM, the sum of IgG subclasses, and the concentration of albumin did not differ significantly between the 2 groups. However, the proportion of IgG1 expressed as percentage of the sum of total IgG was significantly higher (P < 0.01) in the Down syndrome group compared to controls. On the contrary, the proportion of IgG2, IgG3, and IgG4 subclasses in saliva did not differ between the 2 groups. The results indicate an altered distribution of IgG subclasses in saliva, with a higher proportion of IgG1 in Down syndrome individuals compared to controls.

Abstract
BACKGROUND Abnormal thyroid function was shown in children with Down syndrome (DS). This study was undertaken in order to specify these anomalies. POPULATION AND METHODS Thyroid function of 105 children with DS aged from 3 months to 20 years was studied by evaluation of serum concentration of thyrotropin, free T4 (FT4), free T3 (FT3) and reverse T3 (rT3). Each DS child was matched to a control of the same age. RESULTS The mean concentration of thyrotropin of children with DS was increased while the mean concentration of rT3 of the DS children was significantly decreased compared with the controls, as was the ratio rT3/TSH. When DS children are split into two groups, those with and those without increased thyrotropinemia, a significant decrease in the ratio rT3/TSH appeared in DS children with increased thyrotropinemia whereas there is no difference between these two groups regarding to level of FT4, FT3, rT3 and zincemia. However, in all DS children serum zinc levels were lower than in controls. Thyrotropin levels rapidly normalized after thyroxin treatment. CONCLUSION One half of the children with DS have increased thyrotropinemia and all have a decreased rT3.
