Association between suicide attempts and anemia in late-life depression inpatients

BackgroundAnemia is strongly associated with late-life depression (LLD), however, few studies have investigated the relationship between anemia and suicide attempts in LLD patients. It is still challenging to predict suicide risk in patients with depression. Therefore, there is growing interest in potential biomarkers of depressive disorders and suicidal behavior, which may play a significant role in the early diagnosis and treatment of depression. This study aimed to compare serum ferritin, folate, vitamin B12, and erythrocyte parameter levels in patients with LLD with those in healthy older adults, and the relationship between serum ferritin, folate, vitamin B12, and suicide attempts in patients.MethodsSerum ferritin, folate, vitamin B12, and erythrocyte parameter levels were measured in 66 hospitalized LLD patients (30 without suicide attempt, 36 with suicide attempt) and 47 healthy individuals. All participants were surveyed for basic conditions and suicide attempts, and depression was assessed in LLD patients.ResultsSerum ferritin, folate, vitamin B12, red blood cell count, hemoglobin, hematocrit, mean platelet volume and plateletcrit levels were significantly lower in LLD patients compared with healthy older adults (P < 0.05). Further analysis of the relationship between serum ferritin, folate, and vitamin B12 levels and LLD patients’ suicide attempts and showed a significant negative association between serum folate and vitamin B12 and suicide attempts (P < 0.05).ConclusionsSerum ferritin, folate, vitamin B12, red blood cell count, hemoglobin, hematocrit, mean platelet volume and plateletcrit levels were significantly lower in LLD patients than in healthy older adults. In addition, reduced serum folate and vitamin B12 levels in patients may have some effect on suicide attempts. More mechanistic studies are needed to further explain this association.

Two versus three doses of COVID-19 vaccine and post-vaccination COVID-19 infection in hemodialysis patients

Background and aimPatients with chronic kidney disease including those undergoing hemodialysis (HD) constitute a particularly challenging group regarding COVID-19 vaccination. The present study aimed to compare the rate of reinfection after two and three doses of Sinopharm COVID-19 vaccine in HD patients. Patients and methodsThe study included 80 HD patients who received three doses of Sinopharm COVID-19 vaccine. In addition, there were another 80 patients who received only two doses of the vaccine. Patients in the latter group were selected based on propensity matching score with 1:1 ratio. Patients were monitored for post-vaccination COVID-19 infection using PCR examination of nasopharyngeal swabs. Patients were also monitored for post-vaccination complications including general complaints (headache, fever, fatigue), injection site complaints (arm pain, swelling, itching, rash), musculoskeletal complaints (muscle spasm or pain, joint pain) and others. All patients were followed for six months. ResultsThe present study included 80 patients submitted to COVID-19 vaccination with two doses of Sinopharm vaccine (GI) and other 80 patients who received three doses of the same vaccine (GII). At the end of follow up, 11 patients (13.8 %) in GI caught COVID-19 infection. In contrast, no patient in GII had infection (p<0.001). Comparison between patients who had COVID-19 infection and those without infection revealed that the former subgroup had significantly lower BMI (23.3 ± 2.3 versus 27.5 ± 8.1 Kg/m2), higher frequency of associated Hepatitis C (HCV) infection (54.6 % versus 2.9 %, p<0.001) and higher serum ferritin levels [median (IQR): 1101.0 (836.0-1564.0) versus 675.0 (467.0-767.7) ng/mL, p=0.01]. Binary logistic regression analysis identified high serum ferritin levels [OR (95% CI): 0.014 (0.001-0.15), p<0.001] and associated HCV infection [OR (95% CI): 0.99 (0.98-1.01), p=0.02] as significant predictors of post-vaccination COVID-19 infection in multivariate analysis. ConclusionsA three dose regime of Sinopharm COVID-19 vaccine associated with significantly lower rate of reinfection COVID-19 infection in HD patients. Infected patients had significantly lower BMI, higher frequency of HCV and higher ferritin levels.

SERUM FERRITIN AND SERUM LACTATE DEHYDROGENASE LEVELS AMONG COVID-19 PATIENTS

Objectives: The aim of this study was to estimate serum ferritin and serum lactate dehydrogenase (LDH) values among COVID-19-positive and COVID-19-negative subjects. Methods: The study was conducted on 152 cases; 76 were COVID-19 diseased, and 76 were COVID-19 free. Serum ferritin and serum LDH levels were estimated. Result: Average ferritin levels among COVID-19 diseased were 529.33 ng/ml compared to 450.92 ng/ml among negative individuals. Similarly, the LDH level among positive persons was 338.50 IU/L and 303.30 IU/L among hostile people. Conclusion: The uncontrolled and dysfunctional immune response is connected with macrophage activation and hyperferritinemic syndrome. Elevated LDH readings seem to reflect that multiple organ injury and failure may play a more prominent role in influencing the clinical outcomes in patients with COVID-19.

Prevalence of and risk factors for iron deficiency among pregnant women with moderate or severe anaemia in Nigeria: a cross-sectional study

BackgroundAnaemia during pregnancy causes adverse outcomes to the woman and the foetus, including anaemic heart failure, prematurity, and intrauterine growth restriction. Iron deficiency anaemia (IDA) is the leading cause of anaemia and oral iron supplementation during pregnancy is widely recommended. However, little focus is directed to dietary intake. This study estimates the contribution of IDA among pregnant women and examines its risk factors (including dietary) in those with moderate or severe IDA in Lagos and Kano states, Nigeria.MethodsIn this cross-sectional study, 11,582 women were screened for anaemia at 20-32 weeks gestation. The 872 who had moderate or severe anaemia (haemoglobin concentration < 10 g/dL) were included in this study. Iron deficiency was defined as serum ferritin level < 30 ng/mL. We described the sociodemographic and obstetric characteristics of the sample and their self-report of consumption of common food items. We conducted bivariate and multivariable logistic regression analysis to identify risk factors associated with IDA.ResultsIron deficiency was observed among 41% (95%CI: 38 – 45) of women with moderate or severe anaemia and the prevalence increased with gestational age. The odds for IDA reduces from aOR: 0.36 (95%CI: 0.13 – 0.98) among pregnant women who consume green leafy vegetables every 2-3 weeks, to 0.26 (95%CI: 0.09 – 0.73) among daily consumers, compared to those who do not eat it.Daily consumption of edible kaolin clay was associated with increased odds of having IDA compared to non-consumption, aOR 9.13 (95%CI: 3.27 – 25.48). Consumption of soybeans three to four times a week was associated with higher odds of IDA compared to non-consumption, aOR: 1.78 (95%CI: 1.12 – 2.82).ConclusionAbout 4 in 10 women with moderate or severe anaemia during pregnancy had IDA. Our study provides evidence for the protective effect of green leafy vegetables against IDA while self-reported consumption of edible kaolin clay and soybeans appeared to increase the odds of having IDA during pregnancy. Health education on diet during pregnancy needs to be strengthened since this could potentially increase awareness and change behaviours that could reduce IDA among pregnant women with moderate or severe anaemia in Nigeria and other countries.

Ferritin and Ferritin-to-Hemoglobin Ratio as Promising Prognostic Biomarkers of Severity in Acute Pancreatitis-A Cohort Study.

Acute pancreatitis is an inflammation of the pancreas with variable outcomes depending on its severity. Multiple systems of prediction have been proposed, each with variable specificity and sensitivity and with uneven clinical use. Ferritin is a versatile protein associated with various acute and chronic conditions. In our study, we aimed to assess the association of serum ferritin and the ferritin-to-hemoglobin ratio (FHR) with the severity of acute pancreatitis. A retrospective study was conducted in our hospital from January 2020 to September 2022 and included 116 patients with acute pancreatitis (graded according to the revised Atlanta classification). Serum ferritin and FHR were determined next to established laboratory parameters in the first 24 h following admission (hematological parameters, amylase, lipase, C-reactive protein, D-dimers, lactate dehydrogenase). We performed a receiver operating characteristic curve analysis for potential predictors. Also, we made correlations and conducted univariate and multivariate analyses for all potential severity biomarkers. The median values of serum ferritin and FHR differed significantly between patients with severe acute pancreatitis and mild cases (serum ferritin: 352.40 vs. 197.35 ng/mL, p = 0.011; FHR: 23.73 vs. 13.74, p = 0.002) and between patients with organ failure and those without organ failure (serum ferritin: 613.45 vs. 279.65 ng/mL, p = 0.000; FHR: 48.12 vs. 18.64, p = 0.000). The medians of the serum ferritin and FHR levels were significantly higher in non-survivors compared with survivors (serum ferritin: 717.71 vs. 305.67 ng/mL, p = 0.013; FHR: 52.73 vs. 19.58, p = 0.016). Serum ferritin and FHR were good predictors for organ failure and mortality, next to D-dimers and procalcitonin (AUC > 0.753 for organ failure and AUC > 0.794 for mortality). In univariate regression analysis, serum ferritin and FHR were independent variables for moderate-severe forms of acute pancreatitis. Still, adjusting the multivariate analysis, only FHR remained a significant predictor. The cut-offs for serum ferritin and FHR for predicting organ failure were 437.81 ng/mL (sensitivity, 71%; specificity, 75%) and 45.63 (sensitivity, 61%; specificity, 88%), and those for mortality during hospitalization were 516 ng/mL (sensitivity, 83%; specificity, 74%) and 51.58 (sensitivity, 66%; specificity, 86%). Serum ferritin and the ferritin-to-hemoglobin ratio stood out in this study as valuable and accessible predictors of disease severity in the early assessment of acute pancreatitis, next to established severity serum markers (CRP, fibrinogen, D-dimers).

Evaluation of Iron Profiles and Coagulation Profiles in Ischemic Heart Diseases Patients in Elmek Nimir Hospital, Sudan

Background: Ischemic heart disease (IHD) is a constellation of diseases that includes stable angina, unstable angina, myocardial infarction, and sudden cardiac death. It belongs to the group of cardiovascular diseases and is the most common type among them. Iron is an essential trace element. It plays an important role in maintaining various cellular functions and enzymatic reactions. On the other hand, excessive intake of iron is known to be a risk factor for the progression of atherosclerosis. Abnormal iron deposition in the heart causes hemochromatosis and dilated cardiomyopathy, which leads to ischemic heart disease. Objective: This study aims to investigate the role of serum iron, serum ferritin, total iron-binding capacity (TIBC), PT, and PTT in ischemic heart disease (IHD) and their relationship with other risk factors for IHD. Methods: This is a prospective, case-control, cross-sectional analytical study conducted at Elmek Nimir University Hospital, Shendi City, to assess the iron profile and coagulation profile of patients with ischemic heart disease. The study included (30) patients diagnosed with ischemic heart disease and the study group was compared with the mean of the control group (20). Serum iron, ferritin, and TIBC were estimated using a spectrophotometer, and PT and PTT were estimated using manual methods. Data were collected using a structured personal questionnaire and the program (SPSS) version (11.5) was used for data analysis. Results: In this study, patients with ischemic heart disease were (40%) male and (60%) female. In this study, iron averaged (41.0) ug/dl (P. value 0.010), ferritin averaged (233.0) ug/dl (P. value 0.000), and TIBC averaged (44.0) µg/dl. Was shown. (P. value 0.000) compared to mean controls (27.0), (162.0), (56.0). A significant difference was found between the iron profile and his IHD. This study showed the mean PT, PTT for cases (13.4), (40.4) (P-value 0.024), (P. value 0.009) compared with the mean for controls (12.0), (35.1). A significant difference was found between the coagulation profile and IHD. Conclusions: This study concluded that serum levels of iron, ferritin, TIBC, PT, and PTT may be associated with Ischemic heart disease.

Pubertal Development in Girls with Beta Thalassaemia and Assessment of the Adequacy of Chelation Therapy: A Quasi-experimental Study

Introduction: Beta thalassaemia is the most prevalent hereditary autosomal disorder, significantly impacting endocrine function during pubertal development. The pathology is rooted in the excessive deposition of iron in vital organs. If left untreated, this condition leads to serious morbidity and mortality. Hypogonadism stands as the most common endocrine complication. Aim: To observe pubertal development in girls with thalassaemia and evaluate the adequacy of chelation therapy in such patients by measuring levels of Follicle Stimulating Hormone (FSH), Luteinising Hormone (LH), oestrogen, and serum ferritin. Materials and Methods: A quasi-experimental study was conducted at the Thalassaemia Clinic at the Department of Obstetrics and Gynaecology, Burdwan Medical College, Purba Bardhaman, West Bengal, India involving 300 diagnosed Beta Thalassaemia Major (BTM) (case) patients aged 13 to 17 years over a period of one and a half years (January 2020 to June 2021). The girls in the study groups were sequentially enrolled from the Outpatient Department of the Thalassaemia Clinic after meeting inclusion and exclusion criteria. Demographic data, anthropometric measurements, and Sexual Maturity Rating (SMR) were recorded. Hormonal assays of serum FSH, LH, oestrogen, and serum ferritin levels were conducted. Thalassaemic girls with serum ferritin levels exceeding 500 ng/mL received chelation therapy. Serum ferritin levels were measured at two-month intervals for up to six months, with reassessment of serum FSH, LH, oestrogen, and ferritin levels at the end of the six-month period. Statistical analysis was conducted using Statistical Package for Social Sciences (SPSS) version 27.0, Microsoft excel spreadsheet, and Epi Info 7. Results: A total of 190 (63.3%) of the thalassaemic girls were aged 13 to 15 years, with a mean Body Mass Index (BMI) of 22.5000±2.6100 kg/m2 , and 74 of them (38.94%) experienced menarche in this age group. Out of 300 cases, 269 thalassaemic girls (89.6%) received chelation therapy, and 89 cases (33.09%) reached menarche after chelation therapy. A significant (p&lt;0.0001) increase in mean LH and FSH levels was observed after chelation therapy. The mean ferritin level decreased from 3168.85 ng/mL to 2227.24 ng/mL following chelation therapy. Conclusion: Pubertal development failure is common in beta thalassaemic girls. Intervention in the form of adequate chelation therapy in girls with high serum ferritin levels yielded favourable outcomes, as evident from serum gonadotropin and oestrogen levels.

Serum Interleukin-6 and Serum Ferritin Levels Are the Independent Risk Factors for Pneumonia in Elderly Patients.

Pneumonia is a common infection in elderly patients. We explored the correlations of serum interleukin-6 (IL-6) and serum ferritin (SF) levels with immune function/disease severity in elderly pneumonia patients. Subjects were allocated into the mild pneumonia (MP), severe pneumonia (SP), and normal groups, with their age/sex/body mass index/ disease course and severity/blood pressure/comorbidities/medications/prealbumin (PA)/albumin (ALB)/C-reactive protein (CRP)/procalcitonin (PCT)/smoking status documented. The disease severity was evaluated by pneumonia severity index (PSI). T helper 17 (Th17)/regulatory T (Treg) cell ratios and IL-6/SF/immunoglobulin G (IgG)/Th17 cytokine (IL-21)/Treg cytokine (IL-10)/PA/ALB levels were assessed. The correlations between these indexes/independent risk factors in elderly patients with severe pneumonia were evaluated. There were differences in smoking and CRP/PCT/ALB/PA levels among the three groups, but only CRP/ALB were different between the MP/SP groups. Pneumonia patients exhibited up-regulated Th17 cell ratio and serum IL-6/SF/IL-21/IL-10/IgG levels, down-regulated Treg cell ratio, and greater differences were noted in severe cases. Serum IL-6/SF levels were positively correlated with disease severity, immune function, and IL-21/IL-10/IgG levels. Collectively, serum IL-6 and SF levels in elderly pneumonia patients were conspicuously positively correlated with disease severity and IL-21/IL-10/IgG levels. CRP, ALB, IL-6 and SF levels were independent risk factors for severe pneumonia in elderly patients.

Serum ferritin levels in chronic spontaneous urticaria in association with autologous serum skin test: A cross-sectional study

Abstract BACKGROUND: Chronic spontaneous urticaria (CSU) is a common clinical condition presenting with wheals or along with angioedema. It has a complex pathogenesis having a considerable impact on quality of life. In patients with chronic spontaneous urticaria (CSU) exhibiting poor response to conventional treatments, the presence of hyposiderinemia suggests that oral iron therapy could potentially lead to resolution of the urticaria symptoms. OBJECTIVES: (1). To estimate serum ferritin levels in patients with CSU. (2) To assess the correlation between urticarial activity score, autologous serum skin test (ASST), and serum ferritin levels in CSU. MATERIALS AND METHODS: This prospective study enrolled 37 cases of clinically diagnosed CSU attending the dermatology outpatient department from December 2019 to November 2020 after Institutional Ethics Committee approval. ASST and serum ferritin level estimation were done on all patients. The severity of urticaria was calculated using the Urticaria Activity Score. Statistical analysis was done by frequency, standard deviation, and Chi-square test. RESULTS: Among ASST-positive patients, only 4 (19%) had low ferritin levels. No association was found between ASST and serum ferritin levels (P = 0.342). Mean serum ferritin levels in ASST-positive patients were high 91.34 ± 87.24 μg/L which was statistically significant compared to mean serum ferritin levels in ASST-negative patients 49.64 ± 46.91 μg/L. There was significant involvement of palms and soles in ASST-positive patients (P = 0.038). CONCLUSION: Although there was no significant correlation of serum ferritin levels with CSU, oral iron supplementation may be considered an add-on treatment in case of refractory urticaria.

The Exploring of Growth Differentiation Factor-15 and H63D Gene Polymorphisms in β-thalassemia Major: Implications for Cardiovascular Risk and Iron Overload

BACKGROUND: β-thalassemia major (βTM) is a genetic disorder characterized by a deficiency in hemoglobin production, ineffective erythropoiesis, chronic hemolysis, lifelong blood transfusions, iron overload, and increased risk of cardiac complications. OBJECTIVE: The study aimed to evaluate the growth differentiation factor-15 (GDF-15) concentration in βTM patients and its correlation with cardiac complications. H63D refers to a specific mutation in the HFE gene, which is associated with hereditary hemochromatosis (HH), a genetic disorder characterized by excessive accumulation of iron in the body. This mutation involves a change of histidine (H) to aspartic acid (D) at position 63 in the HFE protein. This mutation is often only written abbreviated as (H63D). MATERIALS AND METHODS: This case–control study was done on 120 subjects. A total of 60 patient samples were randomly collected from the Genetic Hematology Center at the Babylon Hospital, with an age range of 10–26 years. In addition, 60 samples were collected from healthy children in the same age range as the control group; patients and controls were subdivided into (10–18) and (18–26) year groups. GDF-15 was measured by enzyme-linked immunosorbent assay, and the genotyping of mutation was done by amplification refractory mutation system-polymerase chain reaction technique. RESULTS: The study revealed a significant increase in ferritin (FER) and GDF-15 levels in the patients compared to controls (P &lt; 0.001). GDF-15 showed a direct correlation with age (r = 0.244, P = 0.02) and FER (r = 0.215, P = 0.04). There was a significant difference in H63D mutations between controls and patients (P = 0.044), with a higher proportion of the C-G (heterozygous for the mutant allele) genotype observed in βTM patients (31.67%). Additionally, a notable effect of the H63D mutation on serum ferritin (higher) levels within the βTM group was observed. CONCLUSION: Elevations of the GDF-15 in βTM patients indicate a high risk of cardiovascular complications in patients with βTM. The H63D mutation of the hemostatic iron regulator (HFE) gene is frequently found in βTM. Although a significant effect of the mutation was obtained on serum FER levels, it did not act as a risk factor in βTM patients. However, the frequent presence of the H63D mutation in patients indicated a possible association between single-nucleotide polymorphism and the iron regulation pathway.

Serum ferritin level in children with normal hemoglobin and low MCV and MCH in a hospital in Iraq

Background: Iron deficiency is common around the world, particularly in young people because of their elevated need for iron to grow and develop. Iron deficiency is demonstrated by low levels of serum ferritin. This research will investigate the level of serum ferritin in children with normal hemoglobin but low MCV and MCH, the purpose of this is to determine the degree to which subclinical iron deficiency is present and distinguish it from other causes of microcytosis. Method: 150 children with typical hemoglobin but low MCV and MCH were recruited recognizing subordinate iron deficiency. Blood samples and demographic information regarding sociological aspects were collected and assessed. A computerized hematology analyzer and an ELISA were both used to assess the level of haemoglobin in the blood and the serum level of ferritin. Results: Children with normal hemoglobin but low MCV and MCH had a mean hemoglobin level of 12.7±0.6 mg/ dl and a serum ferritin level of 86.5±7 ng/ ml, according to the study. The levels of serum ferritin and hemoglobin changed significantly, depending on the sociodemographic variables. Among the pediatric population, the levels of serum ferritin and hemoglobin were significantly higher (P-value 0.002). Conclusion: In children with typical hemoglobin, but low MCV and MCH, the sociodemographic factors are strongly associated with the hemoglobin and serum ferritin levels. Gender, birth order, and family size—children under the age of 10 years— had an effect on the serum level of ferritin. The age, birthdate, and the time of supplemental food consumption also had an effect on hemoglobin levels. These findings demonstrate the necessity of recognizing and treating iron deficiency early on in life.

Association between Body Iron Status and Cognitive Task Performance in a Nationally Representative Sample of Older Adults.

Iron is an essential micronutrient that is necessary for proper cognitive function. However, the dose-response relationship between body iron status and cognitive function remains unclear. The objective of this study was to investigate the association between serum ferritin concentrations, an indicator of body iron status, and cognitive function in older adults. Based on the National Health and Nutrition Examination Survey (NHANES) 1999 -2002 in the United States, nationally representative data was collected from 2,567 adults aged 60 years and older who had objectively measured serum ferritin levels and cognitive performance. High ferritin levels were defined as a serum ferritin level >200 ng/mL in women and >300 ng/mL in men. Low ferritin levels were defined as a serum ferritin level <30 ng/mL. The digit symbol substitution test (DSST) was employed to assess cognitive function. Multivariable logistic regression analyses with survey weights were performed after the DSST was dichotomized at the median score. The weighted prevalence of adults with normal, low, and high serum ferritin levels were 73.98%, 9.12%, and 16.91%, respectively. A U-shaped association between serum ferritin concentrations and cognitive task performance was observed. After adjusting for demographic, socioeconomic, lifestyle, and C-reactive protein factors, the odds ratio (95% confidence intervals) for lower cognitive performance was 1.39 (1.11, 1.74) in adults with high ferritin levels and 1.38 (0.86, 2.22) in adults with low ferritin levels, compared with those with normal ferritin levels. The association between serum ferritin levels and lower cognitive performance was stronger in adults aged 60 to 69 years old than those aged 70 years and older. In conclusion, in a nationally representative sample of older adults in the United States, a high serum ferritin level was significantly associated with worse cognitive task performance. Thus, the relationship between low serum ferritin concentrations and cognitive task performance warrants further investigation.

Association between nonalcoholic steatohepatitis and high serum ferritin levels in type 2 diabetes mellitus.

The aim of this study was to assess the role of elevated serum ferritin levels in the onset, pathological progression and prognosis of nonalcoholic fatty liver disease. Nonalcoholic fatty liver disease has been rapidly increasing worldwide. Despite extensive research on the pathogenesis of nonalcoholic fatty liver disease, a lack of sufficient clinical research on the relationship between nonalcoholic fatty liver disease and serum ferritin levels remains. We analysed 968 patients with type 2 diabetes mellitus who underwent liver ultrasound examination and had their serum ferritin levels measured. The presence of nonalcoholic fatty liver disease and advanced liver fibrosis was determined through abdominal ultrasound examination and the nonalcoholic fatty liver disease fibrosis score. Compared to that in the non-nonalcoholic fatty liver disease group, the presence of hyperferritinemia was significantly more common in the nonalcoholic fatty liver disease group (83.3 vs. 56.3%, p=0.005). When patients with nonalcoholic fatty liver disease were stratified by the nonalcoholic fatty liver disease fibrosis score, those with advanced liver fibrosis exhibited a higher prevalence of hyperferritinemia (56.3, 78.9, and 88.9% for none, simple steatosis, and advanced fibrosis, respectively; p for trend=0.002). In multivariate logistic regression, liver fibrosis was independently associated with hyperferritinemia (odds ratio [OR] 1.45; 95% confidence interval [CI] 1.18-2.02; p=0.014), and this association remained significant in male patients after adjusting for other risk factors (OR 2.66; 95% CI 1.43-5.48; p=0.026). Identifying nonalcoholic fatty liver disease patients at a risk of developing nonalcoholic steatohepatitis and advanced fibrosis is crucial for implementing timely interventions and improving patient outcomes. This study highlights the potential utility of serum ferritin levels as a serum biomarker for identifying nonalcoholic steatohepatitis patients and those at a risk of late-stage fibrosis, particularly in male patients with nonalcoholic fatty liver disease.

Association between anemia and diabetic lower extremity ulcers among US outpatients in the National Health and Nutrition Examination Survey: a retrospective cross-sectional study.

The aim of this study was to explore the relationship between hemoglobin levels, anemia and diabetic lower extremity ulcers in adult outpatient clinics in the United States. A retrospective cross-sectional study was conducted on 1673 participants in the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2004. Three logistic regression models were developed to evaluate the relationship between anemia and diabetic lower extremity ulcers. Model 1 adjusted for demographic and socioeconomic variables (age, sex, race and ethnicity, educational level, family income, and marital status). Model 2 included additional health-related factors (BMI, cardiovascular disease, stroke, family history of diabetes, hyperlipidemia, alcohol and smoking status). Model 3 further included clinical and laboratory variables (HbA1c, CRP, total cholesterol, and serum ferritin levels). Stratified analyses were also conducted based on age, sex, HbA1c level, body mass index (BMI), and serum ferritin level. The study included 1673 adults aged 40 years and older, with a mean age of 64.7 ± 11.8 years, of whom 52.6% were male. The prevalence of diabetic lower extremity ulcers (DLEU) was 8.0% (136 participants). Anemia was found in 239 participants, accounting for 14% of the study group. Model 1 showed an OR of 2.02 (95% CI=1.28~3.19) for anemia, while Model 2 showed an OR of 1.8 (95% CI=1.13~2.87). In Model 3, the OR for DFU in patients with anemia was 1.79 (95% CI=1.11~2.87). Furthermore, when serum ferritin was converted to a categorical variable, there was evidence of an interaction between DLEU status and serum ferritin in increasing the prevalence of DLEU. After adjusting for confounding variables, higher levels of anemia were proportionally associated with an increased risk of incident DLEU. These results suggest that monitoring T2DM patients during follow-up to prevent the development of DLEU may be important. However, further prospective studies are needed to provide additional evidence.

Serum Ferritin as a Prognostic Marker in COVID-19

Abstract Background and Objectives: This study was conducted during the peak of COVID-19 disease with the objective to find the association of serum ferritin and COVID-19 disease severity, to evaluate the utility of serum ferritin as a prognostic marker in COVID-19, and to determine a cutoff value for serum ferritin as a prognostic marker for COVID-19. Materials and Methods: A retrospective study was conducted by the department of biochemistry, in collaboration with the department of medicine in a tertiary care center among 103 patients who were admitted with COVID-19 infection after fulfilling the eligibility criteria. Patients were grouped according to the disease severity and also on the outcome during hospitalization. Results: The serum ferritin level was found to be significantly higher in the severe and critical groups when compared to the mild and moderate groups. However, the difference was not significant between mild and moderate and also between severe and critical groups. The serum ferritin level was also significantly higher in those who did not survive when compared to those who survived. A cutoff value of 635.25 ng/ml was found to have 76% sensitivity and 90.5% specificity to identify patients with severe COVID-19 disease. A cutoff value of 760.65 ng/ml was able to predict mortality with 73.3% sensitivity and 84.1% specificity. Conclusion: Estimating serum ferritin levels in all COVID-19 patients can be beneficial in predicting the progress of the disease and hence aid in the selection of appropriate management.

Can ferritin be a surrogate marker for CD4 cells in human immunodeficiency virus patients? A cross-sectional study of association of serum ferritin levels with immunological staging of human immunodeficiency virus patients.

The human immunodeficiency virus (HIV)/AIDS in India came into public view in 1986 with the detection of the first case of HIV in Chennai, Tamil Nadu, and the first AIDS case in Mumbai, Maharashtra in 1987. In acute phase response, iron distribution occurs in the liver and mononuclear phagocytic system. A high prevalence of elevated serum ferritin levels is reported in HIV infection and serum ferritin levels increase with the clinical worsening of infection and with decreasing CD4 lymphocyte counts. This study is designed to find the role of acute phase reactant serum ferritin in the progression of the disease of HIV which is complicated by opportunistic infections, by finding the correlation of serum ferritin with immunological stages of HIV. This cross-sectional study was conducted on 75 patients admitted to various wards of the Department of Medicine or attending medicine outdoor or ART Centre, Maharana Bhupal Government Hospital, RNT Medical College Udaipur. Serum ferritin, total iron binding capacity, and total serum iron were analyzed in Cobas® analyzer. CD4 cells are measured using the flow cytometry technique. The results were tabulated and subjected to statistical analysis. There was a negative correlation among serum ferritin and CD4 cells with r = -0.195 which was statistically significant (P < 0.05). As the CD4 cell count decreased incidence of serum ferritin increased. Elevation of serum ferritin levels is associated with a low count of the CD4+ in HIV-diagnosed patients. In a patient diagnosed with HIV, elevated serum ferritin indicates underlying inflammatory pathology. Serum ferritin can be used as a guide to further evaluation of underlying disease in HIV patients.

Associations of Vitamin D With GPX4 and Iron Parameters in Chronic Obstructive Pulmonary Disease Patients: A Case-Control Study.

Background: Vitamin D deficiency elevates the risk of chronic obstructive pulmonary disease (COPD) patients. Iron parameters elevation and glutathione peroxidase 4 (GPX4) reduction are involved in the process of COPD. The goal is to explore the associations of vitamin D with GPX4 and iron parameters in COPD patients through a case-control study. Methods: COPD patients and control subjects were enrolled. Serum samples and lung tissues were collected. Serum vitamin D and iron levels and pulmonary ferritin and GPX4 expressions were determined. In addition, human pulmonary epithelial cells (BEAS-2B) were incubated with 1,25(OH)2D3 (100 nM), the active form of vitamin D3. Then, vitamin D receptor (VDR) and nuclear factor (erythroid-derived 2)-like 2 (Nrf-2) signaling were detected. Results: In patients with COPD, serum 25-hydroxyvitamin D (25(OH)D) decreased, and iron and ferritin levels in serum and lung tissues increased. Furthermore, pulmonary expression of GPX4 was reduced. Correlative analyzes indicated that lung function was inversely correlated with iron parameters and positively correlated with GPX4. The results showed that serum 25(OH)D deficiency was associated with an elevation in serum iron parameters and a reduction in pulmonary GPX4. In addition, VDR- and Nrf-2-positive lung nuclei were decreased in COPD patients than in control subjects. In patients with COPD, the results indicated a positive relationship between VDR and Nrf-2. Further analysis revealed that Nrf-2-positive nuclei were negatively correlated with iron parameters. In vitro experiments found that 1,25(OH)2D3 treatment activated VDR signaling and elevated the expression of Nrf-2 and GPX4 in BEAS-2B cells. Conclusions: Vitamin D deficiency is positively associated with GPX4 reduction and iron parameters elevation in COPD patients. It is recommended to explore the role of vitamin D supplementation in the progression of COPD.

Impact of Magnesium and Ferritin Deficiency on Depression Among Adolescent Students.

Depression is considered the fourth-leading cause of health problems. It is the fourth-leading cause of health problems and disability, which causes 16% of the worldwide burden of disease and injury among adolescents. The aim of the present study was to evaluate the possible association of magnesium (Mg) and ferritin deficiency with depression in adolescent students. This case control study in secondary schools at Al-Ghanayem discrete. The total number included was 358 students. All were screened for depression by the Arabic version of the Beck questionnaire. The students who had positive score was selected as cases 86 and a matched same number of students with negative score was selected as controls. Serum level of ferritin and magnesium was measured in the 2 groups. There was statistically significant difference between the studied groups when comparing depression grade with each of ferritin and Mg Depressed group cases had lower mean values of ferritin and Mg. The ferritin cut-off level for the prediction of depression was (35.5 μg/dL, which had a sensitivity of 74.4% and a specificity of 75.6%. The magnesium cut-off levels for the prediction of depression were1.95 mg/dL and 104.5 ng/dL which had a sensitivity of 70% and 64%, respectively. There was a statistically significant negative correlation between depression severity and each of socio-economic status ferritin and Mg. Each of ferritin and Mg were predictors for depression.

Hemoglobin variability in patients receiving EPO and roxadustat during maintenance hemodialysis: a self-control study.

The aim of this study was to investigate the hemoglobin variability in patients undergoing maintenance hemodialysis during the application of erythropoietin (EPO) and roxadustat. For this retrospective study, we analyzed the clinical records of 80 patients with renal anemia on maintenance hemodialysis (MHD) admitted to our hospital between January 2017 and December 2022. We adopted a self-control design comparing the hemoglobin variability of the values before and after roxadustat administration in each patient. The patients received EPO from January 2017 to December 2019 and roxadustat from January 2020 to December 2022. We compared the levels of serum ferritin, transferrin saturation, and hemoglobin and calculated the hemoglobin variabilities by comparing values before and after roxadustat treatments. We found higher transferrin saturation levels at different time points after the roxadustat treatments (p<0.01); meanwhile, the serum ferritin and hemoglobin levels were significantly higher after the roxadustat treatment (p<0.001). During the treatments with EPO and roxadustat, the transferrin saturation, serum ferritin, and hemoglobin levels differed significantly at different time points for each patient (p<0.05). After roxadustat administration, the hemoglobin levels were significantly higher than after EPO administration (p<0.001) and changed more rapidly after roxadustat administration than after EPO administration (p<0.05). The hemoglobin variability after roxadustat administration was significantly lower than that after EPO administration (p<0.05). Treatment with roxadustat led to higher hemoglobin levels and less hemoglobin variability than the treatment with EPO, with high transferrin saturation and higher ferritin levels in patients with renal anemia on MHD.
