The concentrations of SF and sTfR probes were 0.5 mg/mL and 0.5 mg/mL respectively, while those of SF and sTfR detection antibodies were 5 μg/mL and 0.36 μg/mL respectively. Intra- and inter-assay variability was between 3.26% and 18.38% for all tests. The regression coefficients comparing protein microarray with traditional test assays were better than 0.81 for SF and sTfR. Conclusion The present study has established a protein microarray method for combined measurement of SF and sTfR.

Association between Serum Ferritin Levels and Metabolic-associated Fatty Liver Disease in Adults:a Cross-sectional Study Based on the NHANES

Objective Ferritin,initially acting as an iron-storage protein,was found to be associated with metabolic diseases.Our study was designed to investigate the association between serum ferritin and metabolic-associated fatty liver disease(MAFLD)using data from the National Health and Nutrition Examination Survey(NHANES)of the United State of America.Methods A cross-sectional study was conducted,enrolling a total of 2145 participants from the NHANES in the 2017–2018 cycles.Hepatic steatosis and liver fibrosis were assessed by ultrasound images and several non-invasive indexes.Multiple regression analysis was conducted to determine the associations between serum ferritin concentration and MAFLD and liver fibrosis.Results The analysis revealed that participants with higher serum ferritin levels(Q3 and Q4 groups)had a higher prevalence of MAFLD than those with the lowest serum ferritin levels[Q3 vs.Q1:OR=2.17(1.33,3.53),P<0.05 in fatty liver index(FLI);Q4 vs.Q1:OR=3.13(1.91,5.13),P<0.05 in FLI].Additionally,participants with the highest serum ferritin levels(Q4 group)displayed a higher prevalence of liver fibrosis[Q4 vs.Q1:OR=2.59(1.19,5.62),P<0.05 in liver stiffness measurement;OR=5.06(1.12,22.94),P<0.05 in fibrosis-4 index],with significantly increased risk observed in participants with concomitant diabetes[OR=7.45(1.55,35.72),P=0.012].Conclusion Our study revealed that elevated serum ferritin levels are associated with a higher prevalence of MAFLD and advanced liver fibrosis in patients.Elevated serum ferritin levels combined with diabetes are important risk factors for liver fibrosis.

Serum tumor markers (carcinoembryonic antigen, carbohydrate antigen 19-9, carbohydrate antigen 72-4, carbohydrate antigen 24-2, ferritin) and gastric cancer prognosis correlation

BACKGROUND Gastric cancer is a kind of malignant tumor which is prevalent all over the world.Although some progress has been made in the treatment of gastric cancer,its prognosis is still not optimistic,so it is of great significance to find reliable prog-nostic indicators to guide the treatment and management of patients with gastric cancer.AIM To explore the relationship between serum levels of five biomarkers[carcinoem-bryonic antigen(CEA),carbohydrate antigen(CA)19-9,CA72-4,CA24-2,and ferritin]and prognosis in patients with gastric cancer.METHODS This study included 200 patients with gastric adenocarcinoma,and conducted an in-depth analysis of their baseline characteristics,relationship between tumor markers and staging,and prognosis.The study found that CA19-9 has a signi-ficant correlation with tumor stage,the average levels of CA24-2,CEA,CA72-4 and ferritin were slightly increased disregarding the stage of tumor.Survival analysis showed that increases in CEA,CA19-9,CA24-2,and ferritin were all associated with shortened overall survival of patients.Further multivariate ana-lysis revealed that elevated serum CA72-4 levels were an inde-pendent adverse prognostic factor.RESULTS This study reveals that there is a significant correlation between the expression levels of serum tumor markers CEA,CA19-9,CA72-4,CA24-2 and ferritin in patients with gastric cancer and prognosis,and can be used as important indicators for prognostic evaluation of gastric cancer.In particular,markers that appear abnormally elevated initially may help identify gastric cancer patients with poor prognosis.CONCLUSION Serum CEA and CA19-9 play an important role in the prognosis assessment of gastric cancer,and are effective tools to guide clinical practice and optimize individualized treatment strategies for gastric cancer patients.

Association of Red Meat Usual Intake with Serum Ferritin and the Risk of Metabolic Syndrome in Chinese Adults: A Longitudinal Study from the China Health and Nutrition Survey

Objective The present study aimed to investigate the association of red meat usual intake with metabolic syndrome(Met S),and explore the contribution of red meat usual intake to serum ferritin.Methods Based on the data from the longitudinal China Health and Nutrition Survey(CHNS),2,797 healthy adults aged 18–75 years without hypertension,diabetes,and Met S were selected in 2009 as subjects and follow-up studies were carried out till 2015.We used the National Cancer Institute(NCI)method to estimate the usual intake of foods.Multivariable logistic regressions were performed to evaluate the association between red meat usual intake and the risk of Met S.Quantile regression analysis was used to study the relationship between red meat consumption and serum ferritin levels.Results After adjusting for potential confounders,red meat,and fresh red meat were positively associated with the risk of Met S(RR=1.41,95%CI:1.05–1.90 and RR=1.37,95%CI:1.02–1.85,respectively).These relationships showed increasing trend(P<0.05).The level of serum ferritin increased significantly with the number of Met S components(P<0.05).The quantile regression analysis showed that red meat and fresh red meat usual intake had a significant positive association with serum ferritin levels across the entire conditional serum ferritin distribution(P<0.05).Processed red meat did not exhibit a similar association.Conclusion Higher red meat usual intake was associated with an increased risk of Met S and elevated serum ferritin levels.

Serum Ferritin and the Risk of Metabolic Syndrome:A Systematic Review and Dose-Response Meta-Analysis of Cross-sectional Studies

Objective This study aims to assess the dose-response relationship between serum ferritin(SF)and metabolic syndrome(MetS)in the two sexes.Methods We searched for articles on PubMed,the Cochrane Library,EMBASE,and the Web of Science databases that were published from 1950 to 2020.The summary odds ratio(OR)and 95%confidence interval(CI)of the association between SF and MetS were estimated using a random-effects model through a meta-analysis.Based on the methods described by Greenland and Longnecker,we explored the dose-response relationship between the two sexes.Results This study included 14 studies and 74,710 samples.The results of the classical meta-analysis showed that SF was positively associated with MetS(OR=1.77,95%CI:1.59–1.98).Regarding the components of MetS(8 studies included),the results showed that SF was positively associated with abdominal obesity(OR=1.42,95%CI:1.24–1.62),elevated fasting plasma glucose(OR=1.84,95%CI:1.50–2.25),elevated blood pressure(OR=1.17,95%CI:1.08–1.26),elevated triglycerides(OR=2.09,95%CI:1.72–2.54),and reduced high-density lipoprotein cholesterol(OR=1.33,95%CI:1.19–1.49).In the linear dose-response meta-analysis,the ORs of males,females,and postmenopausal females were 1.14(95%CI:1.13–1.16),1.32(95%CI:1.26–1.39),and 1.34(95%CI:1.22–1.47),respectively.Conclusions Our study shows that SF is significantly and positively associated with MetS,and the risk in the male population is higher than that in the female population.This finding also supports the recommendation of using SF as an early warning marker of MetS.

Study on the Correlation between the Expression of Serum Ferritin and Gestational Diabetes Mellitus

Objective: To explore the relationship between serum ferritin (SF) and gestational diabetes mellitus (GDM), for providing new ideas to the prevention and treatment of GDM. Methods: All the pregnant women were selected in Yinan Maternal and Child Health-Care Hospital from December, 2015 to March, 2018 when they were having routine prenatal examination, According to the diagnostic criteria of GDM, 72 patients with GDM were selected as the case group and 72 normal pregnant women were randomly selected as the control group. Fasting venous blood was drawn from all subjects during the first trimester of pregnancy (11-13 weeks) and the second trimester of pregnancy (24-28 weeks). Fasting plasma glucose was measured by glucose oxidase assay and the expression level of SF was determined by electrochemical method. The application value of SF in GDM diagnosis was evaluated by ROC curve. Results: The levels of SF in the case group at early and middle stages are 49.6 ± 18.8 (μg/ml) and 39.8 ± 21.5 (μg/ml), which re 39.4 ± 15.2 (μg/ml) and 32.2 ± 17.6 (μg/ml) in the control group. The levels of SF in the case group were higher than those in the control group (p < 0.05) at early and middle stages. The curve (AUC) of SF level in the diagnosis of GDM was 0.895, p < 0.001; the Youden index was 0.651 and the optimum threshold was 38.6 ng/ml, with a sensitivity of 97.8% and a specificity of 67.3%. Conclusion: The expression level of SF in early pregnancy is correlated with the occurrence of GDM, which may be an important indicator for the prevention and monitoring of GDM.

Serum ferritin levels in children with attention deficit hyperactivity disorder and tic disorder

BACKGROUND Iron plays an important role in neurodevelopmental functions in the brain.Serum ferritin levels are different in children with attention deficit hyperactivity disorder and tic disorder than in healthy children.AIM To explore the current status of iron deficiency in children with neurodevelopmental disorders and its sex and age effects.METHODS A total of 1565 children with attention deficit hyperactivity disorder(ADHD),1694 children with tic disorder(TD),93 children with ASD and 1997 healthy control children were included between January 1,2020,and December 31,2021 at Beijing Children's Hospital.We describe the differences in age levels and ferritin levels between different disease groups and their sex differences.The differences between the sexes in each disease were analyzed using the t test.The incidence rate of low serum ferritin was used to describe the differences between different diseases and different age groups.A chi-square test was used to analyze the difference in the incidence of low serum ferritin between the disease group and the control group.Analysis of variance was used for comparisons between subgroups,and regression analysis was used for confounding factor control.RESULTS A total of 1565 ADHD patients aged 5-12 years were included in this study,and the average serum ferritin levels of male and female children were 36.82±20.64μg/L and 35.64±18.56μg/L,respectively.A total of 1694 TD patients aged 5-12 years were included in this study,and the average serum ferritin levels of male and female children were 35.72±20.15μg/L and 34.54±22.12μg/L,respectively.As age increased,the incidence of low serum ferritin in ADHD and TD first decreased and then increased,and 10 years old was the turning point of rising levels.The incidence of ADHD with low serum ferritin was 8.37%,the incidence of TD with low serum ferritin was 11.04%,and the incidence of the healthy control group with low serum ferritin was 8.61%,among which male children with TD accounted for 9.25%and female children with TD accounted for 11.62%.There was a significant difference among the three groups(P<0.05).In addition,there were 93 children with ASD with an average serum ferritin level of 30.99±18.11μg/L and a serum ferritin incidence of 15.05%.CONCLUSION In conclusion,low serum ferritin is not a risk factor for ADHD or TD.The incidence of low serum ferritin levels in children with ADHD and TD between 5 and 12 years old decreases first and then increases with age.

Effect of minimally invasive intracranial hematoma drainage on inflammatory factors, serum ferritin and serum P substance in patients with hypertensive cerebral hemorrhage

Objective:To study the effect of minimally invasive intracranial hematoma drainage on inflammatory factors, serum ferritin and serum P substance in patients with hypertensive cerebral hemorrhage.Methods:92 cases of hypertensive cerebral hemorrhage patients in our hospital were selected and randomly divided into 2 groups: minimally invasive group (51 cases) and routine group (41 cases). Minimally invasive intracranial hematoma drainage was performed on the minimally invasive group. Bone flap decompression or small bone window craniotomy were used in the routine group. Tumor necrosis factorα (TNF-α), interleukin-6 (IL-6), high sensitive C reactive protein (hs-CRP) and serum protein (SF), serum substance P (SP) in the 2 groups were detected before treatment and 2 weeks after treatment.Results: The comparison of TNF-α, IL-6, hs-CRP, SP, and SF in the two groups before treatment was not statistically significant (P>0.05). TNF-α, IL-6, hs-CRP and SF in both groups after treatment significantly decreased, compared with that before treatment (P<0.01,P<0.05). TNF-α, IL-6, and SF in minimally invasive group decreased more significantly than that in routine group (P<0.01);The comparison of SP in the two groups after treatment significantly increased compared with that before treatment (P<0.01,P<0.05). SP in minimally invasive group increased more significantly than that in routine group (P<0.05).Conclusions:Compared with bone flap decompression or small bone window craniotomy, minimally invasive intracranial hematoma drainage can inhibit inflammatory reaction, reduce the degree of nerve damage and alleviate clinical symptoms more effectively.

Conclusion: The minimally invasive intracranial hematoma evacuation for patients with HICH can effectively improve the levels of SP, SF, inflammatory factors and vascular endothelial function, which is helpful to relieve cerebral edema and lower intracranial pressure, and improve the quality of treatment.

The Potential Clinical Significance of the Serum Iron and Ferritin Status in Lung Cancer Patients

Background An increasing number of studies have shown that iron,one of the indispensable trace elements in the human body,is closely related to the occurrence and development of cancer.However,few studies have clearly demonstrated the role of the iron levels in lung cancer patients,or the potential effects of inflammation on iron levels.Methods The clinical data for lung cancer patients and non-lung cancer participants were retrospectively analyzed.The serum iron and ferritin levels were measured and compared using a rank-sum test.The correlation between the serum iron/ferritin and C-reactive protein(CRP)was analyzed by rank correlation.The cut-off values for continuous variables were obtained by the receiver operating characteristic curve(ROC)method.An analysis of potential prognostic factors in lung cancer patients was conducted by univariate and multivariate survival analyses.Results The serum iron levels in patients with extensive small-cell lung cancer(SCLC)were lower than those with limited-stage SCLC,and the levels of serum ferritin and CRP in those with extensive SCLC were higher than those with limited-stage SCLC.Similarly,the serum iron levels in patients with stage IV non-small cell lung cancer(NSCLC)were lower than those of patients with stageⅠ-Ⅲdisease,and the levels of serum ferritin and CRP in those with stage IV NSCLC were higher than those in stagesⅠ-Ⅲ.The serum iron level was negatively correlated with the level of CRP,while the serum ferritin level was positively correlated with CRP.The stage of lung cancer,but not the serum iron/ferritin level,was an independent prognostic factor in lung cancer patients.Conclusions The serum iron and ferritin levels are associated with the staging of lung cancer.The later stages of lung cancer are associated with a lower serum iron level,a higher serum ferritin level,and a higher CRP level.Inflammation may play an important role in regulating the serum iron and ferritin levels in lung cancer patients.

RADIOIMMUNOASSAY OF SERUM FERRITIN LEVEL IN PATIENTS WITH RECURRENT APHTHOUS ULCERATION

The purpose of this study was to assess the correlation between iron deficiency and recurrent aphthous ulceration (RAU). Radioimmunoassay was used to examine the serum ferritin level (SFL) in 52 patients with RAU and in 54 controls. Both were divided into 2 groups in accordance with sex. The 36 female patients were subdivided into 3 age-groups as follows: 8 aged 22-24, 10 aged 25-34, and 18 aged 35-50 while the male patients were gathered as one single group aged 26-57. The subdivision was adapted similarly for the normal age-grouts. Although no significant difference in SFL was found between the male control and the male patient groups, differences between the female control and female patient groups showed highly significant which levels, with the ascendance of age, were P【0.001, P【0.005 and P【0.001, respectively. Also the difference between male and female control groups were significant (P【0.05). However, no significant differences in SFL were discovered among the 3 patient groups. 10 female patients with SFL【12ng/ml were tested with ferrous sulfate for one month, then their SFL was reexamined one week after the treatment. A highly significant difference in SFL was noted between the pre-ad post-treatment (P【0.001). 9 of them showed that the interval of recurrences were prolonged, the number of ulcers reduced, the pain less intensive and its duration shorter than those before the treatment. This study demonstrated that a singificant decrease in iron-storage occurred in female RAU patients. The authors concluded that the decrease SFL was possibly related to menstruation and child bearing.

Association between Intestinal Helminthiasis and Serum Ferritin Levels Among School Children

Background: Significant iron deficiency anaemia is a major concern in children with helminthiasis, because it may eventually contribute to the growing health challenges of severe anaemia This descriptive cross sectional study was carried out to determine the association between serum ferritin levels and intestinal helminthiasis among school children. Methods: A structured questionnaire was used to collect the study population data. Stool specimens were obtained and examined on the same day using the sedimentation method for identification of the parasite. Blood samples were also obtained for full blood count and serum ferritin measurement. Results: A total of 246 school children were studied with a response rate of 82%. The prevalence of intestinal helminthiasis was 29.7%. The different helminthes identified included Ascaris lumbricoides, Necator americanus, Trichuris trichiura, Strongyloides stercoralis. Of the population studied, 36.2% were anaemic, 15.9% had microcytosis, and 47.6% had hypochromia. The prevalence of ex-hausted iron stores was 3.7%. Serum ferritin levels were significantly lower in children with intestinal helminthiasis compared with controls. Conclusions: The findings in this study demonstrate an inverse re-lationship between intestinal helminthiasis and serum ferritin levels and this is more marked in pupils with hookworm infections. The control of intestinal hel-minthiasis and prevention of iron deficiency anaemia should be given high priority in the implementation of the school health programme.

Analysis of Serum Ferritin Level and Its Clinical Value in Advanced Gastric Cancer

Objective: To investigate the concentration and clinical significance of serum ferritin (SF) in patients diagnosed with advanced gastric cancer before and after treatment. Methods: Forty patients with advanced gastric cancer diagnosed by cytology or pathology in our hospital were selected, including 25 males and 15 females, aged from 48 to 85 years, and the median age was 61.0 years. 40 healthy volunteers matched with age and education were selected as the control group. In order to study the changes of SF level in the treatment of advanced gastric cancer, we divided the patients into effective group (efficacy evaluation as partial remission or complete remission), ineffective group (efficacy evaluation as no remission) and recurrence group according to the efficacy after treatment. Then the difference of SF level between different groups and the relationship between SF level and curative effect were analyzed. There was no significant difference in gender and age among all groups. Results: The SF levels in the newly diagnosed group, stage III patient group and stage IV patient group were significantly higher than those in the control group. The level of SF in stage IV patients was significantly higher than that in stage III patients. There were significant differences in SF level between the effective treatment group, the newly diagnosed group and the ineffective treatment group, but there was no significant difference in SF level between the newly diagnosed group and the ineffective treatment group. Conclusion: SF level has a certain value in the auxiliary diagnosis of gastric cancer, and it also has a certain guiding significance for the evaluation of curative effect and prognosis after treatment.
