Background Immunopathogenesis of dengue infection revealsthe aberrant immune response. Zinc deficiency alters immuneresponse and therefore may associated with clinical severity ofdengue infection.Objective To indentifY the relationship between serum zinc levels and clinical severity of dengue infection in children.Methods A comparative study was conducted at the Departmentof Child Health Hasan Sadikin Hospital Bandung, from Februaryto March 2007. We included children aged ~ 14 years fulfilled theclinical criteria for dengue fever (OF), dengue hemorrhagic fever(DHF), and dengue shock syndrome (DSS) according to WHO(1997), confirmed with serologic test. Subjects were selectedconsecutively until met the sample size for each group. Serumzinc level were measured with atomic absorption spectroscopy(MS) on admission. Data were analyzed using Kruskal-Wallis andPearson chi square test. Significance was considered if P<0.05.Results The serum zinc levels were low in 47 (78.3%) children.The serum zinc level in OF, DHF, and DSS subjects were 56-81 (X±SO= 68.2±8.3) J.Lg/dL; 50-77 (X± SO = 61.6 ± 8. 7) J.Lg/dL;and35-52 (X± SO= 42.7 ± 5.4) j.tg/dL, respectively (P<0.001).The prevalence ratio ofDF to DHF and DHF to DSS were 1.444(P=0.311) and 3.353 (P=0.077), respectively.Conclusion Low serum zinc level were significantly different ineach clinical severity of dengue infection. However, low serum zinc level was not a risk factor for the development of severe dengue infection in children.

Diastolic dysfunction is an emerging challenge among hemodialysis (HD) patients, and the associations between serum zinc with echocardiographic parameters and diastolic function remain uncertain. A total of 185 maintenance HD patients were stratified by the tertiles of serum zinc level to compare their clinical characteristics and echocardiography. Correlations of serum zinc levels with echocardiographic parameters were examined using Pearson’s analysis. Univariate and multivariate logistic regression analyses were performed to investigate the determinants of E/e’ ratio >15 and left atrial volume index (LAVI) > 34 mL/m2, both indicators of diastolic dysfunction. Patients belonging to the first tertile of serum zinc level had a significantly higher E/e’ ratio and LAVI. Serum zinc levels were negatively correlated with E (r = −0.204, p = 0.005), E/e’ ratio (r = −0.217, p = 0.003), and LAVI (r = −0.197, p = 0.007). In a multivariate analysis, older age, diabetes, coronary artery disease, and lower serum zinc levels (OR = 0.974, 95% CI = 0.950–0.999, p = 0.039) were significantly associated with E/e’ ratio >15. Furthermore, diabetes and lower serum zinc levels (OR = 0.978, 95% CI = 0.958–0.999, p = 0.041) were significantly associated with LAVI >34 mL/m2. Reduced serum zinc level was significantly associated with diastolic dysfunction among HD patients. Further prospective studies are warranted to investigate whether zinc supplementation can attenuate cardiac dysfunction in maintenance HD patients.

Background: A seizure is a paroxysmal time-limited change in motor activity and or behavior that results from abnormal electrical activity in the brain. Seizures are common in the pediatric age group and occur in approximately 10% of children. Most seizures in children are provoked by somatic disorders originating outside the brain such as high fever, infection, syncope, head trauma, hypoxia, or toxins. To determine whether children with febrile convulsion have decreased serum zinc level when compared to normal children and children with fever without convulsions.Methods: The study included children admitted with bronchiolitis in between during the period of September 2018 to January 2019 at Department of Pediatrics, Raja Muthiah Medical College and Hospital. It is a case-control study. A sample size of 50 was selected for each group Totally 3 Groups, 1. Children with febrile convulsions,2. Children with fever without convulsions, 3. Normal Children.Results: The mean serum zinc level in children with febrile convulsions was 42.9 mcg/dl. The serum zinc level in children with fever and normal children was 70 mcg/dl and 71 mcg/dl respectively. On comparing the serum zinc level among the three groups statistical significance was obtained between children with febrile convulsions and the other two groups namely normal children and children with fever alone. Thus, decreased serum zinc level is a significant predisposing factor for febrile convulsions. By using Posthoc Multiple comparisons test we came to know that the Fever convulsion group is significantly different from fever and normal group. There is no significant difference between fever and normal group.Conclusions: This study shows that serum zinc levels are decreased in children with febrile convulsions, thus indicating that zinc deprivation plays a significant role in the pathogenesis of febrile convulsions.

Abstract Background: Despite the known associations between zinc levels and Alzheimer’s disease (AD) dementia and related cognitive impairment, the underlying neuropathological links remain poorly understood. We tested the hypothesis that serum zinc level is associated with cerebral beta-amyloid protein (Ab) deposition. Additionally, we explored associations between serum zinc levels and other AD pathologies [i.e., tau deposition and AD-signature cerebral glucose metabolism (AD-CM)] and white matter hyperintensities (WMHs), which are measures of cerebrovascular injury. Methods: A total of 241 cognitively normal older adults between 55 and 90 years of age were enrolled. All the participants underwent comprehensive clinical assessments, serum zinc level measurement, and multimodal brain imaging, including Pittsburgh compound B-positron emission tomography (PET), AV-1451 PET, fluorodeoxyglucose (FDG)-PET, and magnetic resonance imaging. Zinc levels were stratified into three categories: < 80 µg/dL (low), 80 to 90 µg/dL (medium), and > 90 µg/dL (high). Results: A low serum zinc level was significantly associated with increased Ab retention. In addition, apolipoprotein E ε4 allele (APOE4) status moderated the association: the relationship between low zinc level and Ab retention was significant only in APOE4 carriers. Although a low zinc level appeared to reduce AD-CM, the relationship became insignificant on sensitivity analysis including only individuals with no nutritional deficiency. The serum zinc level was associated with neither tau deposition nor the WMH volume. Conclusions: Our findings suggest that decreased serum zinc levels are associated with elevation of brain amyloid deposition. In terms of AD prevention, more attention needs to be paid to the role of zinc.

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: Febrile seizures are the most common cause of convulsions in children and a frequent cause of emergency hospital admissions. There are different hypothesis about neurotransmitters and trace element (such as zinc) changes in cerebrospinal fluid and serum, which can have a role in pathogenesis of febrile convulsions. Hence we want to study this association in our set up. Objectives was to study the association between serum zinc levels and febrile seizures in childern in our set up.Methods: This hospital based, prospective case control study was done in SKIMS Soura Srinagar, Kashmir (J and K), India for one-year period from August 2015 to July 2016. A total of 100 children aged 6 months to 6 years admitted in the hospital presenting with febrile seizures after fulfilling our inclusion and exclusion criteria were enrolled for the study. Informed consent was taken from their attendants and classified into 2 groups of 50 each. Patients with history of simple febrile seizures were taken as cases and those with fever without seizures as controls. A detailed history was taken, and complete physical examination was done on the patients and recorded on a precoded and pretested proforma. Blood was collected within 12 hours of admission and serum zinc levels were estimated. For statistical analysis, SPSS 17 program using t-test was employed. Chi-square test was performed to compare proportion between 2 or more discrete variables. P<0.05 was considered statistically significant.Results: Out of 100 children enrolled, male to female ratio was 1.63:1. Majority of the children were between 6 to 12 months (36%). The clinical presentation comprised of mainly non localized fevers majority of which had clinical evidence to suggest viral etiology (60%), followed by ARI (20%), ASOM (10%), UTI (6%) and bronchiolitis (4%). Mean serum zinc level in cases was 30.96±7.93ugm/dl and in controls it was 35.95±9.25ugm/dl. Serum zinc level was found significantly low in cases of simple febrile seizures as compared to controls (P<0.05).Conclusions: This study reveals that there is positive correlation between low serum zinc levels and febrile convulsions.

AbstractIntroduction.Anemia is a complication of chronic renal failure observed in patients on hemodialysis (HD) affecting morbidity and mortality of these patients. It is associated with erythropoietin (EPO) deficiency and can be treated by human recombinant erythropoietin (hrEPO). Iron deficiency has been reported as the first line cause for inadequate response to this treatment. Zinc deficiency in hemodialysis (HD) patients was previously reported and the relationship between iron and zinc deficiencies has been known for years. The aim of this study was to find out the relationship between serum zinc level, anemia and rhEPO consuming in HD patients.Methods.A total of 69 HD patients and 34 healthy individuals were included in the study. Serum zinc levels, clinical, hematologic, biochemical parameters and rhEPO doses were evaluated.Results.Serum zinc levels were found to be lower in HD patients in comparison to those in the control group (29.92±12.94, 44.82±27.69μg/dL, respectively) (p<0.001). There was a positive correlation between serum zinc and hemoglobin (Hb) in the control group (R2=0.06). In HD patients who needed less then 8000U/week rhEPO, Hb levels (p<0.05) and serum zinc levels were higher. Serum zinc and Hb levels were found to be higher in patients who were under HD treatment for more than 12 months (10.05±1.06 vs 10.69±1.29; p=0.022 and 26.96±13.29 vs 30.88±12.61; p=0.178).Conclusions.HD patients who needed lower dose of EPO had higher serum zinc levels. Although the difference was not statistically significant, these results provide evidence that serum zinc level should be taken into consideration especially in HD patients resistant to EPO therapy.

Acne vulgaris is the most common cutaneous disorder affecting adolescents and young adults. Some studies have reported an association between serum zinc levels and acne vulgaris. We aimed to evaluate the serum zinc level in patients with acne vulgaris and compare it with healthy controls. One hundred patients with acne vulgaris and 100 healthy controls were referred to our clinic. Acne severity was classified according to Global Acne Grading System (GAGS). Atomic absorption spectrophotometry was used to measure serum zinc levels. Mean serum level of zinc in acne patients and controls was 81.31 ± 17.63 μg/dl and 82.63 ± 17.49 μg/dl, respectively. Although the mean serum zinc level was lower in acne group, it was not statistically significant (P=0.598). There was a correlation between serum zinc levels with severity and type of acne lesions. The results of our study suggest that zinc levels may be related to the severity and type of acne lesions in patients with acne vulgaris. Relative decrease of serum zinc level in acne patients suggests a role for zinc in the pathogenesis of acne vulgaris.

Background: Both microvascular and macrovascular complications in diabetes are related to oxidative stress. Zinc which has antioxidant property, delays diabetic complications. The present study was conducted with the objective to study the relationship between serum Zinc level and HbA1C level in newly diagnosed type 2 diabetes mellitus and to compare serum Zinc level with its risk factors.Methods: The present study was a cross sectional study, conducted on 100 patients attending the outpatient department at Rajiv Gandhi Government General Hospital and Madras Medical College, Chennai during the period from May 2015 to October 2015. Of them 50 were newly diagnosed type 2 diabetics and considered as diabetic group and other 50 were considered as controls, who attended the master health check-up. All patients were subjected to thorough general and systemic examination. Under strict aseptic precautions blood sample was collected from all the patients and the serum was investigated for creatinine, urea, zinc, HbA1c, cholesterol, triglycerides and fasting blood glucose. The data obtained were analysed using Microsoft excel software. Correlation was found out in SPSS by using regression equation.Results: The body mass index (BMI) and mean systolic blood pressure (SBP) was significantly higher (p<0.001) in diabetic group as compared to controls. Serum levels of HbA1C and fasting blood glucose (FBG) levels were found to be significantly higher in diabetic group than in controls (p<0.001). Serum zinc levels were significantly higher in control group (p<0.001). Mean zinc value decreases with increase in HbA1c, FBG, BMI, SBP, DBP, triglycerides and cholesterol and the difference was statistically significant (p value <0.01). The relation between Pearson correlation coefficient for zinc and the above parameters were higher in diabetics than controls.Conclusions: Lower serum zinc levels were found to be responsible for the development of macrovascular complications in type-2 diabetics. Hence there is a need for zinc supplementation in diabetic patients to prevent long term complications associated with it.

Background The prognosis of neonatal sepsis can be influenced by various risk factors, one of which is a deficiency of zinc micronutrient substances. Objective To assess for a potential association between serum zinc level and prognosis of infants with early-onset neonatal sepsis (EONS). Methods This prospective cohort study was done in neonates with clinical EONS from September 2017 until December 2018. Serum zinc level was measured on the first day of diagnosis and prognosis was assessed on the fourth day. The association between serum zinc levels and prognosis of EONS was analyzed by Chi-square test and logistic regression with adjustment for confounding variables. Results A total of 70 subjects were divided into two groups based on their serum zinc levels. A cut-off point of 75 ug/dL was used based on area under the curve (sensitivity 91.2% and specificity 93.7%), with accuracy 97.8% (95%CI 0.943 to 1.000; P=0.0001). Subjects with lowzinc level had a 16.8 times greater risk compared to subjects with high serum zinc (RR=16.81; 95% CI 4.35 to 65.02; P <0.0001). Multivariate analysis revealed that subjects with low serum zinc levels had 203.7 times greater risk of worsening than subjects who had a higher serum zinc level (RR 203.72; 95% CI 26.79 to 1549.17; P <0.0001). Covariates such as male sex, low gestational age (<37 weeks), low birth weight (<2,500 grams), asphyxia, Caesarean section delivery, and the presence of comorbidities did not have significant associations with outcomes of EONS (P >0.05). Conclusion Serum zinc level is associated with prognosis of early onset neonatal sepsis, with a cut-off of 75 μg/dL. The high level of serum zinc associates with a better prognosis.

Background. Preeclampsia is defined as gestational hypertension and proteinuria which can be measured by the elevation of liver transaminases to twice normal concentration, and the symptoms of increased intracranial pressure such as dizziness, blurred vision, and seizures. Zinc is an essential mineral for many biological functions and one of the trace elements that is directly involved in the oxidative/antioxidant balance, a pathogenesis process in preeclampsia that is highly dependent on dietary habits and supplements. This study was aimed to assess the association between serum zinc level with preeclampsia (PE). Methods: This observational, case-control study was performed on 90 women with singleton pregnancies at 28 to 42 weeks of gestation which were referred to the Department of Obstetrics and Gynecology, Dr. Mohammad Hoesin General Hospital, Palembang, between August 2020 to November 2020. 30 pregnant women with PE were selected as cases and 60 healthy pregnant women were selected as controls. Maternal serum zinc samples were collected. The collected data were entered into the master table. Tabulation, coding, and statistical data analysis were performed using SPSS version 20.0 for Windows. Results: The mean serum zinc levels in the case group and control group were 43,90 ± 15,79 µg/dL (ranged from 15 to 86 µg/dL) and 48,77 ± 10,54 µg/dL (ranged from 22 to 83 µg/dL), respectively. A value of serum zinc levels with the best sensitivity and specificity was 45,5 µg/dL. Conclusion: There was a significant association between maternal serum zinc level with PE. The risk of PE was 3,2 times higher in pregnant women with serum zinc levels of ≤45,5 mcg/dL compared to pregnant women with serum zinc levels of >45,5 mcg/dL. In this case it is necessary to supplement zinc earlier in pregnancy to reduce the risk of preeclampsia.
