ABSTRACT

Antecedentes: la nutrición durante el embarazo impacta en la salud del recién nacido, con efectos a nivel epigenético determinando consecuencias neurológicas a largo plazo. Las necesidades de hierro durante el embarazo se estiman en 27 mg/día. El hierro hemo que se absorbe mejor se encuentra en la carne. La determinación de ferritina en sangre de cordón umbilical permite evaluar los depósitos de hierro alcanzados durante la etapa fetal. Sus niveles se asociaron con efectos a largo plazo sobre el desarrollo infantil. Objetivos: el objetivo de este estudio de carácter exploratorio es determinar la relación entre el consumo de carnes rojas durante el tercer trimestre de gestación y el nivel de ferritina en el cordón umbilical. Métodos: se realizó un estudio observacional descriptivo con datos recolectados prospectivamente durante un año en el Departamento de Neonatología del Centro Hospitalario Pereira Rossell (CHPR) en Montevideo, Uruguay. Un total de 188 pacientes cumplieron los criterios de inclusión. Se extrajo sangre del cordón umbilical después de un pinzamiento estricto del cordón pasado un minuto de vida. La ferritina se midió utilizando el método de quimioinmunofluorescencia. Se aplicó una encuesta nutricional materna (cualitativo-cuantitativa) que midió la frecuencia de consumo de alimentos con fuente de hierro y las cantidades aproximadas consumidas durante el último trimestre del embarazo. Esta encuesta se centró en el consumo materno de carne vacuna como principal fuente de hierro hemínico en Uruguay. Se analizó la relación entre estas variables. Resultados: el déficit latente de hierro (ferritina en el cordón umbilical <100 ng/ml) se asoció con un menor consumo de carne vacuna durante el embarazo. Valor p de Fisher: 0,0133, OR: 3,71, IC del 95% (1,25-11,05). Conclusiones: este estudio considera adecuada la evidencia que relaciona que los niveles bajos de consumo total de hierro y de carne vacuna durante el tercer trimestre de gestación determinarán un mayor riesgo de déficit latente de hierro y de ferritina medido en el cordón umbilical. Los niveles descendidos de ferritina en cordón umbilical se asocian con un mayor riesgo de efectos adversos a largo plazo sobre la mielinización y el desarrollo neurocognitivo.


Background: nutrition during pregnancy impacts the foetus and the newborn health, it has consequences at the epigenetic level and determines long-term neurological consequences. Iron requirements during pregnancy are estimated at 27 mg/day. Iron is blood absorption from is most efficient from beef. Umbilical cord blood ferritin levels can be used to assess iron deposits reached during the foetal stage. Ferritin levels are linked to the child's long-term development. Objective: this exploratory study's objective is to determine the relationship between beef consumption during the first quarter of pregnancy and ferritin levels in the umbilical cord. Methods: we carried out a descriptive, observational study with prospectively collected data for one-year at the Neonatology Department of the Pereira Rossell Hospital Center (CHPR) in Montevideo, Uruguay. A total of 188 patients met the inclusion criteria. We extracted umbilical cord blood after a strict cord clamping after one minute of life. Ferritin was measured using the chemoimmunofluorescence method. We carried out a maternal nutritional survey using a qualitative-quantitative method and measured the frequency and approximate quantity of iron source food consumption during the last quarter of pregnancy. This survey was focused on maternal beef consumption as the major heme iron source in Uruguay. We analyzed the relationship between these variables. Results: latent iron deficiency (ferritin in the umbilical cord <100 ng / ml) was associated with lower beef consumption during pregnancy. Fisher p-value: 0.0133, OR: 3.71, 95% CI (1.25 - 11.05). Conclusions: this study agrees with the evidence that shows that low levels of total iron and beef consumption during pregnancy determine an increased risk of latent iron deficiency and lower levels of ferritin in newborns, and therefore, greater risk of long-term adverse effects on myelination and neurocognitive development.


Contexto: a nutrição durante a gravidez tem impacto sobre a saúde do recém-nascido, com efeitos no nível epigenético, determinando consequências neurológicas a longo prazo. As necessidades de ferro durante a gravidez são estimadas em 27 mg / dia. O ferro heme de melhor absorção e aquele encontrado na carne vacuna. A determinação da ferritina no sangue do cordão umbilical permite avaliar os depósitos de ferro atingidos na fase fetal. Seus níveis foram associados a efeitos de longo prazo no desenvolvimento das crianças. Objetivos: o objetivo deste estudo exploratório é determinar a relação entre o consumo de carne vermelha durante o terceiro trimestre de gestação e o nível de ferritina no cordão umbilical. Métodos: foi realizado um estudo observacional descritivo com dados coletados prospectivamente durante um ano no Departamento de Neonatologia do Centro Hospitalar Pereira Rossell (CHPR) em Montevidéu, Uruguai. Um total de 188 pacientes cumpriram os critérios de inclusão. O sangue do cordão umbilical foi coletado após clampeamento estrito do cordão após um minuto de vida da criança. A ferritina foi medida pelo método de quimioimunofluorescência. Aplicamos um inquérito nutricional materno (qualitativo-quantitativo) que mediu a frequência de consumo de alimentos com fonte de ferro e as quantidades aproximadas consumidas durante o último trimestre da gravidez. Esta pesquisa enfocou o consumo materno de carne bovina como principal fonte de ferro heme no Uruguai. A relação entre essas variáveis foi analisada. Resultados: a deficiência latente de ferro (ferritina no cordão umbilical <100 mg / ml) foi associada ao menor consumo de carne bovina durante a gestação. Valor de p de Fisher: 0,0133, OR: 3,71, IC 95% (1,25-11,05). Conclusões: este estudo concorda com as evidências que relacionam que os baixos níveis de ferro total e consumo de carne bovina durante o terceiro trimestre de gestação determinam um maior risco de déficit de ferro latente e ferritina mensurado no cordão umbilical. A redução dos níveis de ferritina no cordão umbilical está associada a um risco aumentado de efeitos adversos de longo prazo na mielinização e no desenvolvimento neurocognitivo.

ABSTRACT

Resumen | Introducción. No se dispone de pruebas sensibles ni específicas para diagnosticar la artritis idiopática juvenil sistémica. Objetivo. Evaluar la utilidad diagnóstica de niveles de ferritina total cinco veces por encima del valor normal (ferritina total>5N) y el porcentaje disminuido (menor de o igual a 20 % de la ferritina total) de la ferritina glucosilada (ferritina glucosilada<20 %) para el diagnóstico de artritis idiopática juvenil sistémica en pacientes con fiebre de origen desconocido evaluados por reumatología pediátrica. Materiales y métodos. Se hizo un estudio observacional de pruebas diagnósticas de corte transversal en menores de 16 años hospitalizados entre el 2010 y el 2014. El patrón diagnóstico de referencia fue el cumplimiento de los criterios de clasificación o diagnóstico confirmado en el seguimiento. Se determinaron las medidas de utilidad de las pruebas. Resultados. Se incluyeron 40 pacientes con fiebre de origen desconocido: 11 con artritis idiopática juvenil sistémica y 29 con otros diagnósticos. La mediana de la ferritina total fue mayor en la artritis idiopática juvenil sistémica (3.992 ng/ml) comparada con otras causas de fiebre de origen desconocido (155 ng/ml) (p=0,0027), así como la ferritina total>5N (90,91 % Vs. 51,72 %) (p=0,023). El porcentaje de ferritina glucosilada≤20 % fue de 96,5 % en otras fiebres de origen desconocido en comparación con la artritis idiopática juvenil sistémica (81,8 %) (p=0,178). La ferritina total>5N tuvo una sensibilidad del 91 %, una especificidad del 48 %; un cociente de probabilidades (Likelihood Ratio, LR) positivo de 1,76 y uno negativo de 0,19, demostrando mayor utilidad para el diagnóstico que la combinación de la ferritina total>5N y ferritina glucosilada≤20 %, cuya sensibilidad fue del 81,8 %, la especificidad del 48,3 %, un cociente de probabilidades LR positivo de 1,58 y un LR negativo de 0,38. Conclusión. En pacientes con fiebre de origen desconocido evaluados por reumatología pediátrica, la ferritina total>5N demostró ser útil como prueba de tamización para el diagnóstico de artritis idiopática juvenil sistémica.


Abstract | Introduction: There are no sensitive or specific tests available to diagnose systemic juvenile idiopathic arthritis (sJIA). Objective: To assess the utility as diagnostic tests of total ferritin (TF) levels greater than 5 times the normal value (TF>5N) and the decreased percentage (less than or equal to 20% of TF) of glycosylated ferritin (GF≤20%) for the diagnosis of sJIA in patients with fever of unknown origin evaluated by pediatric rheumatology. Materials and methods: We conducted an observational, cross-sectional study of diagnostic tests in children under 16 years of age hospitalized between 2010 and 2014. The reference diagnostic standard was the fulfillment of the classification criteria or confirmed diagnosis at follow-up. We determined the measures of utility of the tests. Results: We included 40 patients with fever of unknown origin, 11 with sJIA, and 29 with other diagnoses. The median TF was higher in sAIJ (3992 ng/ml) versus other causes of fever of unknown origin (155 ng/ml) (p=0.0027), as well as TF>5N (90.91% versus 51.72%) (p=0.023). The percentage of GF≤20% was higher in patients with other causes of fever of unknown origin (96.5%) compared to sJIA (81.8%) (p=0.178). TF>5N had a sensitivity of 91%, specificity of 48%, positive likelihood ratio (LR) of 1.76, and negative LR of 0.19 demonstrating greater utility for the diagnosis of sJIA than the combination of FT> 5N with GFR <20%, with a sensitivity of 81.8%, specificity of 48.3%, positive LR of 1.58, and negative LR of 0.38. Conclusion: In patients with FUO evaluated by pediatric rheumatology, TF> 5N proved useful as a screening test for the diagnosis of sJIA.

ABSTRACT

RESUMEN La hemocromatosis hereditaria (HH) consiste en una sobrecarga progresiva de hierro que conlleva a un acúmulo anormal del mismo en diferentes órganos blancos; y, que, en caso de no tratarse a tiempo, puede causar una disfunción multi-orgánica. Se han descrito diversas mutaciones genéticas asociadas a la HH, la más frecuente de ellas es la asociada al gen-HFE, la cual se encuentra en el 90% de los casos. En la actualidad la flebotomía terapéutica continúa siendo el tratamiento de elección para el manejo de esta patología. Reportamos el caso de un paciente en seguimiento por fibrosis hepática severa, con persistencia de un perfil ferrocinético elevado, a quien cinco años después se le diagnostica una HH no asociada a una mutación en el gen-HFE; recibió manejo con flebotomías periódicas, presentando rápidamente una mejoría significativa de su cuadro clínico y de los niveles de ferritina al igual que otros paraclínicos.


ABSTRACT Hereditary hemochromatosis (HH) consists of a progressive iron overload that leads to an abnormal accumulation of iron in different target organs; and, if not treated in time, can cause multi-organ dysfunction. Various genetic mutations associated with HH have been described, the most frequent is associated with the HFE-gene, which is found in 90% of cases. At present, therapeutic phlebotomy continues to be the treatment of choice for the management of this pathology. We report the case of a patient under follow-up for severe liver fibrosis, with persistence of a high ferrokinetic profile, who five years later was diagnosed with HH not associated to a mutation in the HFE-gene; He was managed with periodic phlebotomies, rapidly presenting a significant clinical improvement and decrease of ferritin levels.

ABSTRACT

Objective:To analyze the correlation between serum ferritin (SF), perilipin, leptin and the outcome of patients with gestational diabetes mellitus (GDM).Methods:From October 2017 to December 2019, 126 patients with GDM who underwent maternity checkups in Baoding Fourth Central Hospital and gave birth were selected as the GDM group, and 82 normal pregnant women during the same period were selected as the control group for retrospective analysis. The levels of serum SF, perilipin, and leptin in the GDM group and the control group were measured and compared, and the expressions of serum indexes of patients with different blood glucose control and different pregnancy outcomes in the GDM group were measured. Pearson correlation analysis was used to explore the correlation between the expression of serum indexes in GDM patients and fasting blood glucose (FPG), 2 h postprandial blood glucose (2 h PG), and insulin resistance index (HOMA-IR). Logistic regression was used to analyze the relationship between the expression of serum indicators and adverse pregnancy outcomes in GDM patients. The receiver operating characteristic (ROC) curve was used to observe the value of single serum indexes and to predict the pregnancy outcome of GDM patients.Results:The levels of SF, perilipin and leptin in GDM group were higher than those in control group: (152.48 ± 37.64) μg/L vs. (109.27 ± 32.16) μg/L, (857.06 ± 192.35) ng/L vs. (262.83 ± 104.7) ng/L, (23.54 ± 2.28) μg/L vs.(14.62 ± 1.83) μg/L, the differences were statistically significant ( P<0.05). The levels of SF, perilipin and leptin in patients with good blood glucose control in GDM group were lower than those in patients with poor blood glucose control: (132.10 ± 36.52) μg/L vs. (176.37 ± 40.06) μg/L, (176.37 ± 40.06) ng/L vs. (946.42 ± 205.37) ng/L, (21.49 ± 2.16) μg/L vs. (25.94 ± 2.40) μg/L, the differences were statistically significant ( P<0.05). The levels of serum SF, perilipin and leptin in GDM patients were positively correlated with FPG, 2 h PG and HOMA-IR levels ( P<0.05). The levels of serum SF, perilipin and leptin in GDM patients with adverse pregnancy outcomes were higher than those in patients without occurrence: (182.86 ± 42.29) μg/L vs. (138.86 ± 35.47) μg/L, (1 013.35 ± 216.07) ng/L vs. (787.00 ± 183.49) ng/L, (27.04 ± 2.5) μg/L vs. (21.97 ± 2.07) μg/L, the differences were statistically significant ( P<0.05). Logistic regression analysis showed that serum SF, perilipin and leptin were closely related to the adverse pregnancy outcomes in GDM patients ( P<0.05). ROC curve analysis showed that the sensitivity and the specificity of SF, perilipin, leptin combined detection to predict GDM patients with adverse pregnancy outcomes was 76.92% and 83.91%. Conclusions:The serum SF, perilipin and leptin are abnormally high expression in GDM patients, and it is positively correlated with blood glucose level and HOMA-IR. Joint detection can improve the predictive value of adverse pregnancy outcomes and provide a basis for early intervention.

ABSTRACT

Objective:To evaluate the role of nuclear factor E2-related factor 2 (NRF2) in myocardial ischemia-reperfusion (I/R) injury and the relationship with ferroptosis in diabetic rats.Methods:Forty-eight SPF healthy adult male Sprague-Dawley rats, aged 6-8 weeks, weighing 200-220 g, were divided into 5 groups by a random number table method: sham operation group (group S, n=6), myocardial I/R group (group NIR, n=12), diabetes mellitus+ sham operation group (group DS, n=6), diabetes mellitus+ myocardial I/R group (group DIR, n=12) and diabetes mellitus+ myocardial I/R+ NRF2 agonist sulforaphane group (group DIR+ SFN, n=12). Type 1 diabetes mellitus was induced by intraperitoneal injection of 1% streptozotocin-citrate buffer 60 mg/kg.Sulforaphane 500 μg·kg -1·d -1 was injected intraperitoneally before ischemia for 3 consecutive days in group DIR+ SFN.At the 8th week after establishing the model, myocardial I/R was produced by occlusion of the anterior descending branch of the left coronary artery for 30 min followed by reperfusion.At 2 h of reperfusion, the left ventricular systolic pressure (LVSP), HR, and the maximum rate of increase and decrease of left ventricular systolic pressure (±dp/dt max) were recorded.Blood samples were taken from the carotid artery and the animals were then sacrificed for determination of concentration of cardiac troponin I (cTnI) in serum (using enzyme-linked immunosorbent assay), myocardial Fe 2+ and malondialdehyde (MDA) contents, superoxide dismutase (SOD) activity (by colorimetry) and myocardial infarct size (using TTC) and for determination of expression of NRF2, ferroportin1 (FPN1) and acyl-CoA synthetase long-chain family member 4 (ACSL4) (by Western blot), and the pathological changes of lung tissues were observed by hematoxylin-eosin staining. Results:Compared with group S, LVSP, HR, and ±dp/dt max were significantly decreased, serum cTnI concentration and myocardial Fe 2+ and MDA contents were increased, SOD activity was decreased, expression of ACSL4 was up-regulated and expression of NRF2 and FPN1 was down-regulated in group NIR ( P<0.05). Compared with group DS, LVSP, HR, and ±dp/dt max were significantly decreased, serum cTnI concentration and myocardial Fe 2+ and MDA contents were increased, SOD activity was decreased, expression of ACSL4 was up-regulated and expression of NRF2 and FPN1 was down-regulated in group DIR ( P<0.05). Compared with group NIR, LVSP, HR, and ±dp/dt max were significantly decreased, serum cTnI concentration and myocardial Fe 2+ and MDA contents were increased, SOD activity was decreased, myocardial infarct size was increased, expression of ACSL4 was up-regulated and expression of NRF2 and FPN1 was down-regulated in group DIR ( P<0.05). Compared with group DIR, LVSP, HR, and ±dp/dt max were significantly increased, serum cTnI concentration and myocardial Fe 2+ and MDA contents were decreased, SOD activity was increased, myocardial infarct size was decreased, expression of ACSL4 was down-regulated and expression of NRF2 and FPN1 was up-regulated in group DIR+ SFN ( P<0.05). Conclusion:NRF2 is involved in the process of myocardial I/R injury, which is related to promoting ferroptosis in diabetic rats

ABSTRACT

To determine the association between serum ferritin levels, lipid profile and adiposity in school-age children. Methods: A cross-sectional study was conducted on obese and non-obese children. Weight, height, waist circumference and blood pressure were measured for all participants. Lipid profile, serum ferritin and glucose were determined and analysed through absorbance. The Spearman correlation was performed for the quantitative variables and a regression analysis was used to determine the interaction between variables. Eighty-nine children were included, with a median age of 9.0 years. Results: When comparing serum ferritin levels in normal weight group, vs. the overweight and obesity group, values were significantly higher in the latter. Serum ferritin correlated positively with BMI (Rho .282, p <0.01), waist circumference (Rho .372, p < 0.01), diastolic blood pressure (Rho .244, p < 0.05), body fat percentage (Rho .375, p < 0.001), insulin (Rho .254, p <.05) and sex (Rho .224, p <.05); and negatively with high-density lipoprotein cholesterol (Rho. -221, p< 0.05). When analysing the significant variables in a multivariate regression model, sex, body mass index, waist circumference, and body fat percentage remained statistically significant (p <0.01). Conclusion: We observed associations between serum ferritin and obesity in Mexican school aged children(AU)

ABSTRACT

RESUMEN La linfohistiocitosis hemofagocítica (LHH) posterior al trasplante renal hace referencia a un estado hiperinflamatorio grave, asociado a la activación no controlada de los linfocitos T citotóxicos y macrófagos por causa infecciosas y/o secundaria al tratamiento inmunosupresor. Las causas más prevalentes dentro de las infecciones son la histoplasmosis, la tuberculosis y las infecciones por virus herpes. Se caracteriza por fiebre, organomegalias, citopenias, hiperferritinemia, hipertrigliceridemia y/o hipofibrinogenemia; puede acompañarse con hemofagocitosis documentada en la médula ósea, el hígado u otros órganos. Su curso puede ser fulminante con progresión a falla multisistémica y la muerte. El tratamiento va enfocado a controlar tempranamente la causa desencadenante, reducir la inmunosupresión y controlar la inflamación. En pocos casos es necesario el uso de otros inmunosupresores, quimioterapia o, en situaciones muy seleccionadas, se puede requerir el trasplante de médula ósea.


SUMMARY Hemophagocytic lymphohistiocytosis (HLH) in renal transplant recipients is a life-threatening hyper-inflammatory syndrome; associated with uncontrolled activation of cytotoxic T-lymphocytes and macrophages due to infections or immunosuppressive therapy. Histoplasmosis, tuberculosis and herpes virus infection are among the leading infectious causes. It is characterized by fever, organomegaly, cytopenia, hyperferritinemia, hypertrigiceridemia and/or hypofibrinogenemia; which may be accompanied by hemophagocytosis in bone marrow, liver or other organs. HLH can follow a rapidly fatal course, with progression to multisystemic failure and death. The treatment is based on early control of the triggering cause, reducing immunosuppression and stop the inflammatory process. In some cases, is necessary to use other immunosuppressant, chemotherapy and in a very few cases, a bone marrow transplant may be required.

ABSTRACT

Objetivo: Este estudo buscou analisar a presença de anemia, definida como a redução nos níveis de hemoglobina, e relacioná-la com a deficiência de ferritina sérica entre pacientes com idade igual ou superior a 15 anos, identificando possíveis casos de anemia ferropriva. Métodos: Foi realizada a coleta de resultados laboratoriais de pacientes que realizaram o exame de hemograma completo acompanhado da dosagem de ferritina no Laboratório de Análises Clínicas do CESUPA durante o período de agosto de 2018 a junho de 2019. Pacientes que realizaram ambos os exames e revelaram baixos níveis de hemoglobina foram inclusos, obtendo-se assim uma amostra de 177 pacientes anêmicos. Resultados: Nos pacientes incluídos no estudo, constatou-se que a faixa etária com maior prevalência de anemia foi a de pacientes com idade entre 61 a 70 anos de idade, representando 27,1% da amostra total. Classificando-se os tipos de anemia presente com base em seus índices hematimétricos, notou-se maior frequência daquelas com perfil de normocitose e normocromia (55,4%), seguida de microcitose e hipocromia (31,6%) e de macrocitose com normocromia (2,3%). Entre os pacientes com perfil de microcitose e hipocromia, 91,1% apresentaram anisocitose. Dos 177 pacientes anêmicos, apenas 19 (10,7%) apresentaram valores baixos de ferritina, enquanto que os pacientes com níveis normais de ferritina foram os mais frequentes (59,9%). Conclusão: O perfil hematimétrico compatível com quadros de anemia ferropriva foi o segundo mais frequente neste estudo, sendo o de normocitose e normocromia o mais frequente, assim corroborando com maior parte das faixas etárias identificadas.


Objective: This study aimed to analyze the presence of anemia, being evaluated by the reduced hemoglobin levels, and associate it with serum ferritin deficiency among patients at 15 years old or greater, identifying possible cases of iron-deficiency anemia. Methods: Exam results from patients who did the complete blood count exam and the dosage of ferritin levels at the Laboratory of Clinical Analyzes from CESUPA during the interval of august 2018 to june 2019 were collected. Patients who performed both tests and revealed low hemoglobin levels were included, creating a sample of 177 anemic patients. Results: In the patients included in this study, it was found that anemia was most prevalent among patients with an age within the range of 61 to 70 years old, representing 27,1% of the total sample. Classifying the types of anemia present by use of the hematimetric paramaters, it was noted that those with the profile of normocytic and normochromic were the most frequent (55,4%), followed by the profile of microcytic and hypocromic anemia patients with microcytosis and hypochromia, 91,1% also had the presence of anisocytosis. Of the 177 patients with anemia, only 19 (10,7%) showed low ferritin levels, while those with normal ferritin levels were the most frequent (59,9%). Conclusion: The hematimetric profile compatible with iron-deficiency anemia was the second most frequent in this study, while the profile of microcytosis and hypochromia was the most frequent one, thus corroborating with most of the identified age groups.

ABSTRACT

Hemophagocytic lymphohistiocytosis (HLH) is a hyperinflammatory syndrome caused by excessive activation of lymphocytes and macrophages, leading to cytokine storm. Infection-associated HLH is most common, and Epstein-Barr virus is the leading triggers. Quick diagnosis is essential for starting the treatment before irreversible damage. We report a case of 16-year-old boy who presented with unremitted fever, jaundice, and erythematous maculopapular rash all over the body. Investigations showed thrombocytopenia, hyperferritinemia, hypertriglycemia, and the bone marrow biopsy showed hemophagocytosis. Epstein-Barr virus antibody was positive. He responded to chemotherapy as per the HLH-2004 protocol and supportive treatment, and was discharged without complication on day 17.

ABSTRACT

BACKGROUND/OBJECTIVES: Obesity is globally a major public health issue. Evidence suggests that elevated ferritin levels are associated with obesity, dyslipidemia, insulin resistance, and metabolic syndrome. This study was undertaken to examine the relationship between the serum ferritin level and depression in Korean male adults with respect to classification of the prevailing obesity. SUBJECTS/METHODS: This was a case-control study; subjects were classified into obese group (≥ 25.0 kg/m2, 28 subjects) and normal group (18.5–22.9 kg/m2, 27 subjects). A survey was conducted to assess the depression levels as per the guidelines suggested by the Center program for Epidemiological Studies-Depression (CES-D). Blood was collected from each group for assessing biomarkers, and isolated plasma was evaluated for fasting glucose, insulin, quantitative insulin sensitivity check index, and ferritin levels. Data were analyzed, and groups were compared with respect to Body Mass Index (BMI), depression scale and biomarkers. RESULTS: The average depression score of the obesity group was 16.86, which was higher than the normal group (12.56). Subjects scoring more than 16 points comprised 53.6% of the population in the obese group, which was more than double that in the normal group, as assessed by the CES-D program. Furthermore, the serum ferritin level of the obesity group was 207.12 ng/mL, which was higher than that of the normal group (132.66 ng/mL). Lastly, the BMI appeared to be significantly correlated with both depression (r = 0.320, P = 0.017) and elevated ferritin levels (r = 0.352, P = 0.008). CONCLUSION: This study provides evidence of existing correlation between ferritin and depression with obesity.

ABSTRACT

BACKGROUND: Serum-ferritin levels may be associated with psychiatric symptoms among the elderly; however, this association has not been extensively studied. The aim of this study was to evaluate the association between serum-ferritin levels and mental health issues in older Koreans. METHODS: This cross-sectional study included large-scale national data from the Korea National Health and Nutrition Examination Survey 2010–2012. In total, 1,802 older Koreans (≥65 years old) were included. The assessed psychiatric symptoms included short sleep duration, stress, depressed mood, and suicidal ideation. Any association between serum-ferritin levels and mental health issues according to sex was examined using logistic regression analysis. RESULTS: The prevalence of short sleep duration, stress, depressed mood, and suicidal ideation was 50.9%, 21.7%, 18.2%, and 22.5%, respectively. In men, suicidal ideation decreased with increased serum-ferritin levels after multivariate adjustment for sociodemographic and lifestyle factors and comorbidities. The odds ratios (OR) and 95% confidence interval (CI) of suicidal ideation by quartiles of serum-ferritin level were 1 (reference), 1.132 (95% CI, 0.569–2.252), 0.453 (95% CI, 0.217–0.945), and 0.608 (95% CI, 0.295–1.253), respectively, (P for trend=0.039). In women, no trend was observed. However, compared to the lowest quartile, short sleep duration (<7 h) and stress perception were significantly decreased in the third quartile, with odds ratios of 0.601 (95% CI, 0.461–0.888), and 0.606 (95% CI, 0.386–0.952), respectively. CONCLUSION: Moderate serum-ferritin levels were associated with decreased risk for suicide ideation in men, and were associated with decreased short sleep duration and stress perception in women.

ABSTRACT

Objective@#To investigate the effect of endogenous iron accumulation onbone mass, intraosseous vessels and the effect of exogenous iron on endothelial cell activity.@*Methods@#The mice were divided into control group (C57/BL6 mice without hepcidin knockout) and hepcidin-knockout group (10 mice in each group, 8 weeks old and weighing about 22 g). The mice in both groups were killed at the age of 16 weeks. Serum ferritin levels were measured by Enzyme-linked immunosorbent assay (ELISA), and iron accumulation in liver tissue was measured by Prussian blue staining, while femoral micro-structure was measured by micro-CT, and H-type vessel immunofluorescence staining was used to detect the number of H-vessels in bone. Cell experiments were divided into normal culture group (normal cell group) and intervention group (Fe group) with 200 μmol/L ammonium ferric citrate. Scratch test was used to detect the migration ability of vascular endothelial cells, and tube formation test was used to detect the function of vascular endothelial cells. The endothelial activity of vascular endothelial cells was detected by immunofluorescence.@*Results@#The level of serum ferritin (318.30±12.53 ng/ml) in the hepcidin-knockout group was significantly higher than that in control group (109.60±4.66 ng/ml). The percentage of blue area of Prussian liver iron staining in the hepcidin-knockout group (80.80%±3.156%) was significantly higher than that in control group (20.94%±2.813%). Bone mineral density in the hepcidin-knockout group (0.044±0.002 mg/m3) was significantly higher than that in control group (0.131±0.008 mg/m3). The number of intraosseous blood vessels in the hepcidin-depleted mice (17.06%±1.060%) was significantly lower than that in control group (38.76%±4.576%). There were significant differences between the two groups in each index (t=-49.367,-13.788, 35.293, 6.165; all P < 0.05). The scratches of vascular endothelial cells in Fe group were reduced by 24.300%±1.849% after 24 hours of culture, which was significantly lower than that in normal group (39.060%±3.211%). The area of vascular endothelial cells in Fe group (0.035±0.003 mm2) was significantly lower than that in normal group (0.330±0.018 mm2). The EMCN positive cells of vascular endothelial cells in Fe group were significantly lower than those in normal group. The percentage of cell number (12.000%±3.462%) was significantly lower than that of normal cell group (0.035%±0.003%). There were significant differences in cell indices between the two groups (t=9.790, 18.929, 13.922; all P< 0.05).@*Conclusion@#Endogenous iron accumulation aggravated bone loss in mice, and the number of intraosseous blood vessels decreased significantly. Vascular endothelial cells were inhibited by iron intervention in migration, tube-formation and endothelial ability.

ABSTRACT

Objective To explore the clinical value of serum ferritin (SF),erythrocyte sedimentation rate (ESR) and erythrocyte average indexes [mean corpuscular volume (MCV),mean corpuscular hemoglobin (MCH),mean corpuscular hemoglobin concentration (MCHC)] in the prognosis evaluation of patients with small cell lung cancer (SCLC).Methods A total of 72 SCLC patients were enrolled in the Haian People's Hospital Affiliated to Nantong University from January 2013 to October 2016 (SCLC group),and 80 health controls were selected at the same time (control group).The levels of serum SF,ESR and erythrocyte average indexes in SCLC group and control group were detected,and their relationships with clinical features,prognosis and survival time were analyzed.Results The serum levels of SF,ESR,MCV,MCH and MCHC in SCLC patients were (309 ±59) μg/L,(16 ±4) mm/h,(104 ± 12) fl,(32 ±4) pg and (307 ±21) g/L,respectively.The serum levels of SF,ESR,MCV,MCH and MCHC in control group were (186 ±26) μg/L,(15 ±5)mm/h,(85 ± 7) fl,(30 ± 3) pg and (335 ± 25) g/L,respectively.Compared with the control group,the patients in SCLC group were significantly increased on the levels of SF (t =14.168,P < 0.001) and MCV (t =6.143,P < 0.001),and were significantly decreased on the level of MCHC (t =-4.220,P =0.003).There were no significant difference in the levels of ESR (t =1.931,P =0.102) and MCH (t =1.220,P =0.313) between the two groups.The serum levels of SF and MCV were significantly correlated with the stage of SCLC (t =-4.092,P =0.009;t =-4.985,P < 0.001).Multivariate logistic regression analysis showed that high serum SF (OR =5.31,95% CI:3.09-9.31,P < 0.001) and MCV (OR =1.78,95% CI:1.10-3.08,P =0.013) were independent risk factors of SCLC.Survival analysis showed that the survival time of the patients in the high SF group was significantly shorter than that in the low SF group (6 months vs.20 months;x2 =6.556,P =0.001).Conclusion Serum ESR,MCH and MCHC levels are not significantly correlated with SCLC,but serum SF and MCV levels are of important clinical significance in evaluating the prognosis of SCLC patients.

ABSTRACT

Objective To clarify the function of LIM and SH3 domain protein-1 (LASP1) and ferritin in rhBMP2-induced osteogenic differentiation of beagle bone marrow mesenchymal stem cells (BMSCs).Methods After BMSCs from 3-18-month-old C57BL/6J mice were cultured adherently for 24 hours,they were subjected to osteogenic differentiation for 7,14 and 21 days in 3 groups.BMP2 (100 μg/L) and osteogenic differentiation medium was added in the experimental group,only osteogenic differentiation medium was added in the control group,and nothing was added in the blank group.Osteoblast differentiation was determined by examining marker genes (Runx2,OSX,OCN and OPN) using qRT-PCR.The protein expression of both LASP1 and ferritin was investigated using western blotting.After LASP1 and ferritin were silenced in the cells in the experimental group after transfection of shRNA to target LASP1(m),rhBMP2-induced osteogenesis was repeated to verify the roles of LASP1 and ferritin in osteoblast differentiation.Results The qRT-PCR showed successful osteoblast differentiation in the experimental group.Western blotting verified significant down-regulation of LASP1 and up-regulation of ferritin in the experimental group.After the LASP1 gene was silenced,the expression levels of osteoblast differentiation marker genes in the experimental group were higher than those in the control group.Conclusions rhBMP2 can induce mouse BMSCs to differentiate into osteoblasts in a significant manner.Combined with our preliminary research,the present study may confirm that LASP1 and ferritin,which play an important role in regulating cytoskeleton activity and iron metabolism,are critical in the osteogenic differentiation of mouse BMSCs induced by rhBMP2.
