Background Suboptimal zinc intake may depress thymus function,lymphoproliferation, and T cell-dependent B-cell proliferation,which can impair antibody production. Zinc supplementation canimprove immune function and reduce morbidity.Objective To assess the effect of zinc supplementation on infants'anti-HBs titer after hepatitis B vaccination.Methods A double-blind randomized control trial of 66 healthyinfants in Pustu Dauh Puri, Denpasar Barat was conducted. Subjectswere followed from birth to three months of age and were placedinto two treatment groups using block randomization. One groupreceived zinc supplements with a standard hepatitis B vaccination(zinc group, n=33) and the other group received placebosupplements with standard hepatitis B vaccination (placebo group,n=33). The serum zinc levels were measured at baseline and atthree months. The difference in levels of anti-HBs titer between thezinc and placebo groups was the primary endpoint of this study.Results The serum zinc levels were significantly higher in the zincgroup compared to the placebo group (P = 0.017), with a meandifference of 18.76 miU/ml (95% CI 3.45 to 34.07). Regardlessof baseline serum zinc levels, the mean anti-HBs titers weresignificantly higher in the zinc group compared to the placebogroup (P <0.0001; mean difference = 495.8 miU/mL; 95%CI 362.32 to 629.44). Multivariate analysis showed that zincsupplementation was the only variable that influenced anti-HBstiter levels (P < 0.0001).Conclusion Regardless of their initial zinc serum level, infantsreceiving zinc supplements along with standard hepatitis Bvaccination have significantly higher levels of anti-HBs titersthan infants receiving hepatitis B vaccination without zincsupplements.

Background: In sports such as roller skates, endurance can lead to increased inflammation and muscle cell damage, free radical formation, and zinc excretion from sweat and urine that affect the increased redistribution of zinc from blood to tissue. This mechanism causes a decrease in blood zinc levels, erythrocyte numbers and hemoglobin concentrations, increased leukocyte counts and the body’s oxidative stress parameters that have an impact on the athlete’s performance decline. Zinc supplementation may be given to maintain the athlete’s hematologic parameters during endurance exercise.Objectives: To examine the effect of zinc supplementation on serum zinc level, hemoglobin concentration, erythrocyte and leukocyte counts, and blood MDA level of skate athletes after endurance exercise.Method: This study was an experimental clinical trial using pre and post-test designs on 8 athletes incorporated in the Pre-PON DIY Wheels Team. The study was conducted in two periods, one week of endurance exercise without zinc supplementation and one week of endurance exercise with 30 mg/d of zinc supplementation. Blood sampling was performed on the seventh day of each period, before and after endurance training.Results: There was a decrease in erythrocytes and hemoglobin concentration, and a significant increase in leukocyte count after endurance training in both periods (p<0.05), but no significant difference in serum zinc levels and MDA levels after endurance training in both periods (p>0.05). Although there were no significant differences in all athlete hematologic parameters between two treatments (p>0.05), there was an improvement in serum zinc levels, hemoglobin concentrations, erythrocyte, and leukocyte counts.Conclusion: Zinc supplementation 30 mg/day for one week did not have a significant effect on the athlete’s hematology parameters after endurance exercise.

Background: Zinc deficiency is highly prevalent and is caused by inadequate dietary intake, malabsorption and removal by treatment in hemodialysis patients. This study investigated the relationship between serum zinc levels and nutritional status in hemodialysis patients. Methods: A cross-sectional study examining 87 hemodialysis patients was performed. The serum concentrations of zinc were studied to evaluate their association with nutritional status, which was assessed by measuring abdominal muscle and fat areas with computed tomography. Results: Serum zinc levels were significantly and positively correlated with subcutaneous and visceral fat areas (r = 0.299, p < 0.01, and r = 0.298, p < 0.01, respectively), but not abdominal muscle areas. Multiple regression analyses demonstrated that serum zinc levels were a significant independent predictor of visceral fat areas (p < 0.01), but not subcutaneous fat areas (p = 0.631). Conclusions: Our findings suggest that serum zinc levels could play a crucial role in determining abdominal fat mass in hemodialysis patients.

Introduction: Tuberculosis (TB) still remains a leading killer from a single infectious agent worldwide, especially in Asia and Africa. Achieving the Sustainable Development Goal (SDG) 3 will be contingent on addressing ways of reducing the impact of TB to the health, socio-economic and health system of populations most at risk. Micronutrients supplementation is increasingly being recognized as having great potentials to that effect. Objective: This study thus assessed the potential benefits or otherwise of zinc supplementation on tuberculosis treatment outcomes in Calabar, Nigeria. Methods: Eligible patients (81) out of the 182 assessed were randomized to receive anti-TB drug regimen plus oral administration of individual zinc, 25 mg daily for 60 days (intervention group), while the control group received anti-tuberculosis drug regimen only for 60 days. Both qualitative and quantitative data were collected. Clinical examination, Karnofsky performance scale index, direct sputum examination, anthropometric measurements and blood collection for haematological and zinc assessment were carried out before and 2 months after anti-TB treatment began.  Difference in treatment effects between and within groups for continuous variables was tested using t-test. Mantel-Haenszel summary estimate of the relative risk (RR) was used to test the clinical effectiveness of the intervention. The Pearson test was applied to determine the correlation between variables. Main Results: The mean serum zinc levels at 2 months of TB treatment were significantly higher in the intervention group (14.4 ± 0.37µmol/L) in comparison with the control (12.9 ± 0.37 µmol/L); (p = 0.004). A significant difference (p = 0.010) in the serum concentrations of zinc was observed between the two groups when adjustments were made for TB-HIV co-infection. Risk reduction of about 41% for acid fast bacilli (AFB) positivity (RR: 0.59; 95% CI 0.23 to 1.46) was observed after 2 months of anti-TB treatment in favour of the intervention group. Similarly, intervention group had significantly (p = 0.005) lower proportion of patients with serum zinc levels < 10.7 µmol/L (intervention: 5; Control 10) and (p = 0.030) BMI < 18.5 kg /m2 below the lower ranges ((intervention: 9; Control 16). There was a significant improvement in the haematological parameters as evidenced by significant higher proportion of patients in the intervention group than the control group with values above the lower ranges for these parameters with risk reductions in favour of the intervention group for lower ranges as 34%, 12%, 73% and 58% respectively for haemoglobin, albumin, serum total protein and globulins. Conclusion: Irrespective of HIV status in individuals with tuberculosis, zinc micronutrient supplementation significantly increases clinical outcomes, haematological parameters, improves nutritional status as proxied by anthropometric indices and leads to faster sputum smear conversion. The study adds to the growing body of evidence in support of the beneficial role of zinc in TB control.

Abstract Background Zinc is an essential micronutrient for maintaining biological activity. The level of zinc in the blood is known to decrease with age, especially in those over 75 years of age. In older adults patients with impaired functional status, aspiration pneumonia based on dysphagia often becomes problematic. However, the relationship between zinc deficiency and swallowing function has not been studied before. Methods A total of 52 older adults subjects (15 males and 37 females) living in a nursing home were enrolled for this study. At the time of enrollment, data of gender, age, body weight, serum zinc levels, serum albumin levels, and the time in a simple 2-step swallowing provocation test (S-SPT) were collected. In patients with serum zinc levels < 60 μg/dL, we initiated 2 months of oral zinc supplementation therapy with a 34 mg/day zinc load. Those who underwent zinc supplementation were re-evaluated after the treatment period and serum zinc levels and S-SPT time were measured. Results At the time of enrollment, serum zinc level was significantly correlated with serum albumin levels (Pearson’s R = 0.58, p < 0.0001) and time in the S-SPT (Spearman’s rho = − 0.32, p = 0.0219). Twenty-five of the 52 patients had zinc deficiency with a serum zinc level < 60 μg/dL. After 2 months of oral zinc supplementation, both serum zinc levels (p < 0.0001) and time in the S-SPT (p = 0.04) significantly improved. Meanwhile, serum albumin level (p = 0.48) or body weight (p = 0.07) did not significantly change following zinc supplementation. Zinc supplementation significantly improved swallowing function, especially in the older adults who had comorbid dysphagia and zinc deficiency. Conclusions Zinc deficiency is associated with compromised swallowing function in older adults patients with impaired general functions. Oral zinc supplementation can alleviate dysphagia in older adults patients with zinc deficiency even though this is a retrospective study. Further study will be needed to confirm this positive effect.

We aimed to examine the effects of zinc supplementation on nutritional status, lipid profile, and antioxidant and anti-inflammatory therapies in maintenance hemodialysis (MHD) patients. We performed a systematic review and meta-analysis of randomized, controlled clinical trials of zinc supplementation. Metaregression analyses were utilized to determine the cause of discrepancy. Begg and Egger tests were performed to assess publication bias. Subgroup analysis was utilized to investigate the effects of zinc supplementation in certain conditions. In the crude pooled results, we found that zinc supplementation resulted in higher serum zinc levels (weighted mean difference [WMD] = 28.489;P<0.001), higher dietary protein intake (WMD = 8.012;P<0.001), higher superoxide dismutase levels (WMD = 357.568;P=0.001), and lower levels of C-reactive protein (WMD = −8.618;P=0.015) and malondialdehyde (WMD = −1.275;P<0.001). The results showed no differences in lipid profile. In the metaregression analysis, we found that serum zinc levels correlated positively with intervention time (β=0.272;P=0.042) and varied greatly by ethnicity (P=0.023). Results from Begg and Egger tests showed that there was no significant bias in our meta-analysis (P>0.1). Results of subgroup analysis supported the above results. Our analysis shows that zinc supplementation may benefit the nutritional status of MHD patients and show a time-effect relationship.
