Currently, the Japanese society of clinical nutrition (JSCN) defines serum zinc (Zn) level < 60 μg/dL as Zn deficiency and 60 μg/dL ≤ serum Zn level < 80 μg/dL as subclinical Zn deficiency, and 80 μg/dL ≤ serum Zn level < 130 μg/dL as normal Zn range. We aimed to elucidate the prognostic impact of this Zn classification system in patients with liver cirrhosis (LC) compared to the Child–Pugh classification and the albumin–bilirubin (ALBI) grading system (n = 441, median age = 66 years). The Akaike information criterion (AIC) with each evaluation method was tested in order to compare the overall survival (OS). The median serum Zn level was 65 μg/dL. There were 56 patients with normal Zn level, 227 with subclinical Zn deficiency and 158 with Zn deficiency. OS was well stratified among three groups of serum Zn level (p < 0.0001). The AIC value for survival by the Zn classification system was the lowest among three prognostic models (AIC: 518.99 in the Child–Pugh classification, 502.411 in ALBI grade and 482.762 in the Zn classification system). Multivariate analyses of factors associated with OS revealed that serum Zn classification by JSCN was an independent factor. In conclusion, the serum Zn classification proposed by JSCN appears to be helpful for estimating prognosis in LC patients.

Background: Micronutrient deficiency is a major problem in many developing countries. Micronutrient especially Zn deficiency may affect pregnancies, delivery, and outcome of pregnancy.Objectives: To study serum Zn level in full term mother and non pregnant women in order to compare with those of non pregnant women as reference value. Method: This cross sectional study was carried out in the Department of Physiology, Sir Salimullah Medical College Mitford Hospital, Dhaka, during the period of 1st January 2009 to 31st December 2009. A total number of 55 subjects were included in this study, among them 27 were full term delivery mothers (group B), treated as study group. Age range of full term mother was from 20-40 years. Again, 28 non pregnant women with age range from 20-30 years were taken as a control group. Statistical analysis was done by using appropriate method as applicable.Results: Mean serum Zn level were significantly lower (p<0.001) in full term pregnant mother in comparison to those of non pregnant women.Conclusions: The present study revealed a lower level of zinc in full term mother than non pregnant women. The decreased serum Zn level may be due to poor nutritional status during pregnancy as serum total protein and albumin levels were also lower in this group of subjects. http://dx.doi.org/10.3329/bjpp.v26i1-2.19960 Bangladesh J Physiol Pharmacol 2010; 26(1&2) : 17-20

We aimed to clarify the impact of the serum zinc (Zn) level grading system proposed by the Japanese society of clinical nutrition (JSCN: 80 μg/dL ≤ serum Zn level < 130 μg/dL (type A), 60 μg/dL ≤ serum Zn level < 80 μg/dL (type B), and serum Zn level < 60 μg/dL (type C)) in patients with hepatitis C virus (HCV)-related liver cirrhosis (LC) on the incidence of composite hepatic events (Com-HEs) compared with Child–Pugh (C–P) classification or albumin-bilirubin (ALBI) grade. (n = 275, median age = 67 years). The Akaike information criterion (AIC) was compared among three prognostic models. Factors associated with the incidence of Com-HEs were also studied. The first incidence of any HE was confirmed in 112 patients (40.7%). The AIC value for Com-HEs by the Zn level grading system was the lowest among the three prognostic models (AIC: 301.788 in Zn level grading system, 303.372 in ALBI grade, and 333.953 in C–P classification). In the multivariate analysis, male (p = 0.0031), ALBI grade 3 (p = 0.0041), type B (p = 0.0238), type C (p = 0.0004), and persistent viremia (p < 0.0001) were significant factors associated with the incidence of Com-HEs. In conclusion, the serum Zn level grading system proposed by JSCN can be helpful for estimating the incidence of Com-HEs in HCV-related LC patients.

Background and aims: Preterm birth can cause high morbidity and mortality in women. Previous evidence has confirmed the association between zinc (Zn) deficiency in x women and some pregnancy complications. This study investigated the association between serum Zn concentration in pregnant women and preterm birth. Methods: This case-control study focused on evaluating 76 pregnant women with preterm birth (case group) and 62 pregnant women with term birth (control group) and was conducted in the obstetrics ward of Hajar hospital, Shahrekord, Iran in 2014. The Zn level was measured by spectrophotometry and data were analyzed by SPSS, version 15. Results: The prevalence of Zn deficiency was 95.6%. The mean of serum Zn concentration was 39.62±11.83 and 59.81±8.8 in the preterm and term delivery groups, respectively (P<0.001). Similarly, the mean of serum Zn concentrations was 43.06±15.6 and 50.46±13.8 in women with and without the rupture of pregnancy membranes, respectively (P=0.01). Based on the findings, the serum Zn concentration was not significantly associated with parity (P=0.634). Conclusion: Although a decrease in the serum Zn concentration could lead to premature rupture of membranes during pregnancy and preterm birth, it could not be considered as the main factor for preterm birth. In addition, Zn deficiency was highly prevalent in pregnant women. Therefore, nutritional interventions should be performed to prevent complications due to the deficiency of micronutrients such as Zn so that to increase health maintenance in mothers and children.

Introduction: Frailty syndrome (FS), as a health problem in elderly, can interfere with the quality of life. Many factors play roles in its occurrence, one of which is oxidative stress. Superoxide dismutase (SOD), in which one of its components is zinc (Zn), is one of the endogenous antioxidants that plays a role in preventing oxidative stress. This study was aimed to know the correlation between serum zinc level (sZn) and erythrocyte SOD (eSOD) activity in non-frail and frail geriatric patients.Methods: This was cross-sectional study with consecutive sampling method conducted in the Geriatric Clinic Cipto Mangunkusumo hospital, from August through September 2014, on 60 patients (30 patients for each group of non-frail and frail). Data were collected from interviews, physical measurements, and venous blood sampling.Results: Among 90% of the subjects had low Zn intake, at the same time, the mean of sZn was 8.41 ± 1.36mol/l and 93.3% of the subjects had experienced Zn deficiency. The mean of eSOD activity was 1526 ± 508U/gHb, and there was no significant difference between the groups. There were no significant correlation between sZn and eSOD activity both in the overall subject (r = -0.04; p = 0.076), as well as the non-frail group (r = -0.099; p=0.604) and frail  group (r = 0.01; p = 0.957).Conclusion: Serum zinc level did not have any significant correlation with the eSOD activity, neither on overall or both non-frail and frail groups.

We sought to investigate the influence of serum zinc (Zn) concentration on sarcopenia in chronic liver diseases (CLDs, n = 372, median age = 65 years, 147 liver cirrhosis (LC) cases (39.5%)). Sarcopenia was defined by low grip strength and low skeletal muscle mass. Study subjects were divided into the following three groups (High-, Intermediate-, and Low-Zn groups) based on the baseline serum Zn level. The impacts of serum Zn concentration on sarcopenia were examined. The median (interquartile range) serum Zn concentration for all cases was 72.85 (63.7, 81.45) μg/dL. The proportions of sarcopenia in the High-Zn, Intermediate-Zn, and Low-Zn groups were 10.75% (10/93), 11.23% (21/187), and 27.17% (25/92), respectively (P = 0.9046 (High vs. Intermediate), P = 0.0007 (Intermediate vs. Low), P = 0.0044 (High vs. Low), overall P value = 0.0009). The median serum Zn concentrations in patients with sarcopenia, pre-sarcopenia, and control were 66.35, 73.1 and 73.8 μg/dL, respectively (P = 0.0234 (sarcopenia vs. pre-sarcopenia), P = 0.2116 (pre-sarcopenia vs. control), P = 0.0002 (sarcopenia vs. control), overall P value = 0.0016). In the multivariate analyses of factors linked to the presence of sarcopenia, Low-Zn was an independent predictor for all cases (P = 0.0236) and LC cases (P = 0.0082). In conclusion, Zn deficiency can be an independent predictor for sarcopenia in patients with CLDs.

Background: Hypozincemia may be found in different trimesters of pregnancy. Gradual alteration of this micronutrient status during pregnancy is associated with increased maternal and infant mortality and morbidity. Objective: To measure serum zinc level of pregnant women in different trimesters in order to find out their micronutrient status. Method: This cross sectional study was carried out in the Department of Physiology, Sir Salimullah Medical College, Dhaka between 1st January 2010 to 31st December 2010. 90 normal pregnant women, age ranged from 20 to 30 years were included in the study group (Group-B) which was further divided into group B1 consisting of 30 different pregnant women in 1st trimester, group B2 consisting of 30 different pregnant women in 2nd trimester and group B3 consisting of 30 different pregnant women in 3rd trimester. Age matched 30 apparently healthy nonpregnant women (Group A) were also selected by for comparison. Serum zinc level was measured by Spectrophotometric method and serum total protein and albumin levels were estimated by standard laboratory technique. Statistical analysis was done by using ANOVA & Spearman rank Correlation as applicable. Result: In this study, serum Zn level was significantly lower in 1st (p<0.01), 2nd and 3rd trimester (p<0.001) of pregnant women in comparison to that of non-pregnant women. Again, this value was significantly (p<0.001) lower in 3rd trimester than those of 1st and 2nd trimesters of pregnant women. Moreover, serum Zn concentration showed negative correlation (r=-0.621) with different trimesters of gestation and this correlation was statistically significant (p< 0.001).  Conclusion: This study reveals that gradual hypozincemia was observed in pregnant women from 1st to 3rd trimester of gestation.

We sought to clarify the correlation between non-protein respiratory quotient (npRQ) in indirect calorimetry and serum zinc (Zn) level in chronic liver diseases (CLDs, n = 586, 309 liver cirrhosis (LC) patients, median age = 63 years). Clinical parameters potentially linked to npRQ <0.85 (best cutoff point for the prognosis in LC patients) were also examined in receiver operating characteristic curve (ROC) analyses. The median npRQ was 0.86. The median serum Zn level was 64 μg/dL. The median npRQ in patients with non-LC, Child–Pugh A, Child–Pugh B and Child–Pugh C were 0.89, 0.85, 0.83 and 0.82 (overall p < 0.0001)). The median serum Zn level in patients with npRQ <0.85 (58 μg/dL) was significantly lower than that in patients with npRQ ≥ 0.85 (68 μg/dL) (p < 0.0001). The correlation coefficient (r) between npRQ level and serum Zn level for all cases was 0.40 (p < 0.0001). Similar tendencies were observed in all subgroup analyses. The highest correlation coefficient between serum Zn level and npRQ was found in patients with Child–Pugh C (n = 22, r = 0.69). In ROC analyses for npRQ <0.85, serum Zn level had the highest area under the ROC (AUC) among baseline laboratory parameters (AUC = 0.69). In conclusion, serum Zn level can be helpful for npRQ in patients with CLDs.

Frailty Score

We sought to examine the serum zinc (Zn) level and frailty in patients with chronic liver diseases (CLDs, n = 285, 107 liver cirrhosis cases, median age = 66 years). Frailty was defined as a clinical syndrome in which three or more of the following criteria were met (frailty score 3, 4, or 5): unintentional body weight loss, self-reported exhaustion, muscle weakness (grip strength: <26 kg in men and <18 kg in women), slow walking speed (<1.0 m/s), and low physical activity. Robust (frailty score 0), prefrail (frailty score 1 or 2), and frailty were found in 90 (31.6%), 157 (55.1%), and 38 (13.3%), respectively. The median serum Zn levels in patients with frailty, prefrailty, and robust were 59.7 μg/dL, 72.8 μg/dL, and 76.9 μg/dL, respectively (p-values: frailty vs. prefrail, p < 0.0001; prefrail vs. robust, p = 0.0063; frailty vs. robust, p < 0.0001; overall p < 0.0001). For all cases, variables with absolute values of correlation coefficient with frailty score (0–5) ≥ 0.3 were age (rs = 0.3570, p < 0.0001), serum albumin (rs = −0.3212, p < 0.0001), extracellular water to total body water ratio using bioimpedance analysis (rs = 0.4386, p < 0.0001), and serum Zn level (rs = −0.3406, p < 0.0001). In conclusion, decreased serum Zn level in patients with CLDs can be closely associated with the presence of frailty.

Zinc (Zn) is essential for appropriate growth and proper immune function, both of which may be impaired in thalassemia children. Factors that can affect serum Zn levels in these patients may be related to their disease or treatment or nutritional causes. We assessed the serum Zn levels of children with thalassemia paired with a sibling. Zn levels were obtained from 30 children in Islamabad, Pakistan. Serum Zn levels and anthropometric data measures were compared among siblings. Thalassemia patients’ median age was 4.5 years (range 1–10.6 years) and siblings was 7.8 years (range 1.1–17 years). The median serum Zn levels for both groups were within normal range: 100 μg/dL (10 μg/dL–297 μg/dL) for patients and 92 μg/dL (13 μg/dL–212 μg/dL) for siblings. There was no significant difference between the two groups. Patients’ serum Zn values correlated positively with their corresponding siblings (r=0.635,P<0.001). There were no correlations between patients’ Zn levels, height for age Z-scores, serum ferritin levels, chelation, or blood counts (including both total leukocyte and absolute lymphocyte counts). Patients’ serum Zn values correlated with their siblings’ values. In this study, patients with thalassemia do not seem to have disease-related Zn deficiency.
