Ferritin as proinflamatory biomarker of iron metabolism in tuberculosis patients (review)

Traditional methods of tuberculosis (TB) diagnosis, including sputum microscopy and culture for Mycobacterium tuberculosis detection, are time-consuming or have unsatisfactory sensitivity. However, early diagnosis of TB with high accuracy and sensitivity is very important for disease outcomes and prevention. Therefore, there is an urgent need for new TB diagnostic methods based on TB-associated biomarkers, with rapid availability of results that do not require sputum analysis, are inexpensive, and have high sensitivity and specificity. Objective — to study the mechanisms of ferritin participation in the pathogenesis of tuberculosis basing on the literature data. Materials and methods. 242 literature sources were found in the PubMed system by the query «Ferritin AND Tuberculosis» and 40 of them were selected for further detailed study. Results and discussion. Studies have shown that serum iron and transferrin concentrations are lower and ferritin levels are higher in patients with TB compared to those without TB. These deviations in the concentration of ferritin and transferrin usually normalize after treatment. Lower transferrin levels are associated with both early and late TB progression, and higher ferritin and hepcidin levels are associated with a higher risk of early TB progression in TB contacts. In addition, the status of biomarkers of iron metabolism can be used as an indicator of treatment failure (low ferritin) and mortality (high ferritin). Finally, low levels of transferrin and serum iron, as well as high ferritin concentrations in HIV-infected patients predict an increased risk of TB disease and relapse. Conclusions. Iron metabolism between M. tuberculosis and the host organism is closely related and plays an important role in the pathogenesis of tuberculosis. Parameters of iron metabolism are promising markers of both the course and effectiveness of tuberculosis treatment. In particular, changes in the level of ferritin can be predictors of both the ineffectiveness of tuberculosis treatment and mortality from this disease, so the prognostic value of this marker requires further detailed study.

Prognostic Value of Serum Transferrin Level before Radiotherapy on Radio-Sensitivity and Survival in Patients with Nasopharyngeal Carcinoma.

To investigate the prognostic value of serum transferrin (TRF) level before intensity-modulated radiation therapy (IMRT) on radio-sensitivity and overall survival (OS) in patients with nasopharyngeal carcinoma (NPC). From October 2012 to October 2016, a total of 348 patients with NPC in the First Affiliated Hospital of Fujian Medical University were retrospectively analyzed in our study. The concentration of serum TRF was detected by the method of enzyme-linked immunosorbent assay (ELISA). In the whole group, 46 patients received IMRT, and 302 patients received IMRT plus chemotherapy. The radio-sensitive tumor was defined when the local tumor lesions disappeared completely in the nasopharyngeal MRI scan and no tumor residues were found under the electronic nasopharyngoscope one month after the end of radiotherapy. The serum TRF level before IMRT was (1.34-3.89) g/L, with a median of 2.16 g/L and a mean of (2.20 ± 0.42) g/L. In the whole group, 242 cases (69.5%) were radiosensitive, and 106 cases (30.5%) were insensitive. The number of radiosensitive patients in the group of HTRF (transferrin > 2.16 g/L) and LTRF (transferrin ≤ 2.16 g/L) before radiotherapy was 129 (74.6%) and 113 (64.6%), respectively. The difference in radio-sensitivity between the two groups was statistically significant (χ2 = 4.103, p = 0.043). Logistic regression analysis showed that the level of TRF before radiotherapy (OR = 1.702; 95% CI 1.044~2.775; p = 0.033) was an independent factor for radio-sensitivity. The log-rank test showed that patients in the LTRF group achieved a significantly worse OS (χ2 = 5.388, p = 0.02) than those in the HTRF group. Cox regression analysis showed that baseline TRF level (HR = 1.706; 95% CI 1.065~2.731; p = 0.026) was an independent prognostic factor for overall survival. The low level of TRF before IMRT is a risk factor for radio-sensitivity and a prognostic factor for poor OS in NPC patients. It may be a promising marker to predict radio-sensitivity and OS in NPC patients who accept IMRT.

Kritik COVID-19 Hastalarında Mortaliteyi Tahmin Etmede İnflamatuvar Belirteçlerin Rolü: Tek Merkezli, Geriye Dönük, Gözlemsel Bir Çalışma

Introduction: This study aims to assess the association of inflammatory markers with the clinical progression of patients diagnosed with COVID-19. Materials and Methods: Critically ill patients with COVID-19 were included. Prealbumin, lactate dehydrogenase (LDH), transferrin, procalcitonin, ferritin, D-dimer, troponin T and C-reactive protein (CRP) were monitored. A comparison was performed between patients regarding their need for mechanical ventilation, duration of hospital and intensive care unit stay, discharge, mortality, complications, and response to treatment in order to reveal potential correlations. Results: A total of 107 patients were enrolled in the study. D-dimer levels on the 3rd and 6th days were significantly higher in the exitus group. Prealbumin and transferrin levels measured at baseline and on days three and six were significantly lower in the exitus group compared to the surviving group (p˂ 0.05). In the exitus group, the procalcitonin, CRP, LDH, troponin T, and ferritin levels were significantly higher on days zero, three, and six as compared to the surviving group (p˂ 0.05). Conclusion: Our results suggest that inflammatory markers may be useful as early indicators of mortality in COVID-19 patients.

Excessive Erythrocytosis Is Not Associated With Altered Iron Homeostasis in Men From the World's Highest City.

Excessive Erythrocytosis Is Not Associated With Altered Iron Homeostasis in Men From the World's Highest City.

Glutathione S-transferase zeta 1 alters the HMGB1/GPX4 axis to drive ferroptosis in bladder cancer cells.

The ability of glutathione S-transferase zeta 1 (GSTZ1) to modulate homeostasis of cellular redox and induce ferroptosis was explored in bladder cancer cells, and the involvement of the high mobility group protein 1/glutathione peroxidase 4 (HMGB1/GPX4) in these effects was studied. BIU-87 cells stably overexpressing GSTZ1 were transfected with appropriate plasmids to deplete HMGB1 or overexpress GPX4, then treated with deferoxamine and ferrostatin-1. Antiproliferative effects were assessed by quantifying levels of ferroptosis markers, such as iron, glutathione (GSH), malondialdehyde (MDA), reactive oxygen species (ROS), GPX4, transferrin, and ferritin. GSTZ1 was significantly downregulated in bladder cancer cells. GSTZ1 overexpression downregulated GPX4 and GSH, while greatly increasing levels of iron, MDA, ROS, and transferrin. GSTZ1 overexpression also decreased proliferation of BIU-87 cells and activated HMGB1/GPX4 signaling. The effects of GSTZ1 on ferroptosis and proliferation were antagonized by HMGB1 knockdown or GPX4 overexpression. GSTZ1 induces ferroptotic cell death and alters cellular redox homeostasis in bladder cancer cells, and these effects involve activation of the HMGB1/GPX4 axis.

Circulating Proteins and Metabolite Biomarkers in Gastric Cancer: A Systematic Review and Meta-analysis

Gastric cancer (GC) is often diagnosed at an advanced stage and thus patients have a poor prognosis. This implies that early detection of this cancer will improve patient prognosis and survival. This systematic review explored the association of circulating protein and metabolite biomarkers with GC development. A literature search was conducted until November 2021 on Medline, Embase, Cochrane library, and Web of Science databases. Studies were included if they assessed circulating proteins and metabolites in blood, urine, or saliva and determined their association with GC risk. Quality of identified studies was determined using the Newcastle-Ottawa scale for cohort studies. Random and fixed effects meta-analyses were performed to calculate pooled odds ratio. A total of 53 studies were included. High levels of anti-Helicobacter pylORi IgG levels, pepsinogen I (PGI) <30 µg/L and serum pepsinogen I/ pepsinogen II (PGI/II) ratio<3 were positively associated with risk of developing GC (pooled odds ratio (OR): 2.70; 95% CI: 1.44-5.04, 5.96, 95% CI: 2.65-13.42 and 4.43; 95% CI: 3.04-6.47). In addition, an inverse relationship was found between ferritin, iron and transferrin levels and risk of developing GC (OR: 0.62; 95% CI: 0.38-1,0.97; 95% CI: 0.94-1 and 0.85; 95% CI: 0.76-0.94). However, there was no association between levels of glucose, cholesterol, vitamin C, vitamin B12, vitamin A, α-Carotene, β-Carotene, α-Tocopherol, γ-Tocopherol, and GC risk. The pooled analysis demonstrated that high levels of anti-Helicobacter pylORi IgG, PGI<30µg/L and serum PGI/II ratio <3 and low levels of ferritin, iron and transferrin were associated with risk of GC.

Ferroptosis Activation Contributes to the Formation of Skin Lesions in Psoriasis Vulgaris

(1) Background: Ferroptosis is a newly coined form of programmed cell death marked by lethal accumulation of lipid peroxidation and ferrous iron overload. A few studies on the specific mechanism of ferroptosis in the genesis and development of psoriasis are available. (2) Methods: Levels of lipid reactive oxygen species (ROS) and ferrous iron were measured by flow cytometry. Ultrastructure analysis was performed by transmission electron microscopy. Imiquimod-induced psoriasis-like mice were treated with a ferroptosis inducer. The expressions of mRNA of genes were measured by qRT-PCR. HaCaT cells were used to explore the function of Cyb561d2. (3) Results: In this work, we observed that levels of lipid ROS and ferrous iron in the epidermis of psoriasis vulgaris (PV) patients were increased. The existence of ferroptosis activation in the epidermis of individuals with PV was confirmed by transmission electron microscope both in patients with PV and psoriasis-like mice models. Intradermal injection of the ferroptosis inducer RSL3 in psoriasis-like mice significantly promoted and aggravated the development of psoriasis-like dermatitis, and the level of serum transferrin was also increased in PV samples. Moreover, abnormal expression of some genes related to iron metabolism was also proved in the epidermis of PV cases, among which Cyb561d2 was shown to promote ferrous iron overload and lipid peroxidation accumulation in HaCaT cells. (4) Conclusions: In summary, our study suggested that ferroptosis activation owing to iron overload may be a novel mechanism underlying the formation of skin lesions in individuals with PV.

Nutritional Biomarkers as Predictors of Dysphonia Severity in Patients with Ischemic Stroke.

Dysphonia and malnutrition are major problems in patients who have suffered an ischemic stroke. Tools to assess dysphonia severity include the dysphonia severity index (DSI) and maximum phonation time (MPT). This study aimed to investigate whether the nutritional biomarkers transferrin, albumin, and prealbumin could be predictors of dysphonia severity. A retrospective analysis was conducted between January 2018 and October 2022. A total of 180 patients who had suffered an ischemic stroke were included. Serum transferrin, albumin, and prealbumin levels were significantly correlated with DSI and MPT levels. In a multiple regression analysis, prealbumin and transferrin were significant predictors of DSI, whereas only prealbumin was a significant predictor of MPT. Serum transferrin, albumin, and prealbumin levels in patients who have suffered an ischemic stroke may correlate with dysphonia severity as assessed using DSI and MPT. These results may provide objective evidence that nutritional biomarkers affect dysphonia severity.

Effect of transferrin glycation induced by high glucose on HK-2 cells in vitro.

Glycation is a common post-transcriptional modification of proteins. Previous studies have shown that advanced glycation end modified transferrin (AGE-Tf) levels in diabetic rat kidney tissues were increased; however, its role in diabetic nephropathy remains unclear. In this study, differences in glycation degree and Tf sites induced by differing high glucose concentrations in vitro and the effect on total iron binding capacity (TIBC) were observed. Moreover, the effect of AGE-Tf on human renal tubular epithelial cells (HK-2) was investigated. In vitro Tf was incubated with increasing glucose concentrations (0 mM, 5.6 mM, 11.1 mM, 33.3 mM, 100 mM, 500 mM, and 1,000 mM) for AGE-Tf. Differences in AGE-Tf glycation degree and TIBC level were analyzed via colorimetric method. The AGE-Tf glycation sites were identified with LC-MS/MS. HK-2 cells were treated with AGE-Tf prepared with different glucose concentrations (33.3 mM and 500 mM) in vitro. The effects of AGE-Tf on HK-2 cell viability, proliferation, oxidative stress index, and Tf receptor expression levels were then observed. With increasing glucose concentrations (100 mM, 500 mM, and 1,000 mM) in vitro, Tf glycation degree was significantly increased. The TIBC levels of AGE-Tf were decreased significantly with increasing glucose concentrations (33.3 mM, 100 mM, 500 mM, and 1,000 mM). Four glycated modification sites in Tf and 17 glycated modification sites were detected in AGE-Tf (500 mM) by LC-MS/MS. The structural types of AGEs were CML, G-H1, FL-1H2O, FL, and MG-H1. No significant differences were found in the survival rate of HK-2 cells among the AGE-Tf (500 mM), AGE-Tf (33.3 mM), and Tf groups (all p > 0.05). The apoptosis rate of HK-2 cells in the AGE-Tf (500 mM) group was significantly higher than that in the AGE-Tf (33.3 mM) group. Additionally, both of them were significantly higher than that in the Tf group (both p < 0.05). The MDA levels of HK-2 cells in the AGE-Tf (500 mM) and AGE-Tf (33.3 mM) groups were higher than that in the Tf group, but not significantly (both p > 0.05). The T-AOC level of HK-2 in the AGE-Tf (500 mM) group was significantly lower than that in the AGE-Tf (33.3 mM) and Tf groups (both p < 0.001). The GSH level of HK-2 cells in the AGE-Tf (500 mM) group was significantly lower than that in the Tf group (p < 0.05). The expression level of TfR in the AGE-Tf (500 mM) group was also significantly lower than that in the Tf group (p < 0.05). The degree and sites of Tf glycation were increased in vitro secondary to high-glucose exposure; however, the binding ability of Tf to iron decreased gradually. After HK-2 was stimulated by AGE-Tf in vitro, the apoptosis of cells was increased, antioxidant capacity was decreased, and TfR expression levels were downregulated.

Long-COVID sequelae are associated with oxidative stress in hemodialysis patients

pathophysiology of long-COVID sequelae in the general population of SARS-CoV-2-infected patients has been shown to be strongly influenced by oxidative stress. However, the potential role of oxidative stress in the development of long-COVID sequelae in hemodialysis patients (HD) has never been investigated.&#x0D; The present study aimed to evaluate the oxidative status of HD patients 3.5 months after SARS-CoV-2 infection in relation to the presence of long-COVID sequelae and the severity of the acute phase COVID-19.&#x0D; Methods. This cross-sectional cohort study included 63 HD patients with a median age of 55 (43-62.5) years and a dialysis vintage of 42 (25-73) months who had been infected with COVID-19 at least 3 months before recruitment. Patients were divided into two groups according to the occurrence of long-COVID sequelae: Group 1 included 31 (49.2%) HD patients with sequelae, while Group 2 included 32 (50.8%) fully recovered individuals. At 3.5 (3.2-4.6) months after the acute phase of COVID-19, malondialdehyde (MDA) and erythrocyte levels (MDAe), sulfhydryl groups (SH -groups), serum catalase activity, transferrin, and ceruloplasmin were measured. A comparison of the obtained data was performed using the Student’s test or the Mann-Whitney test according to the data distribution. A correlation was evaluated with the Spearman test.&#x0D; Results. HD patients with persistent long-COVID sequelae had significantly higher concentrations of MDAs (p = 0.002), MDAe (p = 0.0006), and CTs (p = 0.02), and lower serum levels of SH-groups (p = 0.03) and ceruloplasmin (p = 0.03) compared with Group 2. The concentration of most studied indicators of pro- and antioxidant status did not depend on the severity of the acute phase COVID-19, and only catalase activity was statistically significantly related to the need for hospitalization (r = 0.59; p = 0.001), oxygen support (r = 0.44; p = 0.02), and the percentage of lung injury according to computed tomography (p = 0.03). Although the serum concentration of transferrin did not differ between the studied groups, the individual analysis showed that its value was statistically higher in HD patients with severe COVID-19 even 3.5 months after infection (p &lt; 0.0001).&#x0D; Conclusions. Long-term COVID-19 sequelae in HD patients are associated with oxidative stress. High levels of catalase activity and serum transferrin 3.5 months after COVID-19 may be a consequence of the severe course of the acute phase of the disease. The obtained data suggest that the use of antioxidants may be one of the possible strategies to treat the long-term consequences of COVID in HD patients.&#x0D;

Predictive value of ferroptosis-related biomarkers for diabetic kidney disease: a prospective observational study

AimsTo explore the predictive value of ferroptosis-related (FR) biomarkers for diabetic kidney disease (DKD) in patients with type 2 diabetes mellitus (T2DM).MethodsThis prospective observational study enrolled patients with T2DM at the Second Hospital of Jilin University between December 2021 and March 2022. DKD was measured by the urinary albumin-to-creatinine ratio. Receiver operating characteristic curve (ROC) analysis was performed to assess the predictive value of ferroptosis-related biomarkers for DKD.The risk factors for massive proteinuria were performed by multivariable logistic regression analysis.ResultsFinally, 118 patients (53.0 ± 12.2 years, 76 males) were enrolled, 52 of them without DKD (had normal proteinuria), while 66 with DKD. (Forty-one had microproteinuria, and 25 had massive proteinuria.) FR biomarkers, including acyl-CoA synthase long chain family member 4 (ACSL4), malondialdehyde (MDA), and reactive oxygen species (ROS), were significantly higher in the massive proteinuria group than in the other groups, while glutathione peroxidase 4 (GPX4) was significantly lower (all P < 0.05). The area under the ROC of the combination of GPX4, ACSL4, MDA, and ROS for predicting DKD was 0.804 (P < 0.001). Additionally, multivariate logistic regression analysis showed that the course of disease and ferritin levels were independent risk factors for massive proteinuria, while high serum iron, transferrin, and GPX4 levels were independent protective factors for massive proteinuria in patients with T2DM (all P < 0.05).ConclusionsThe GPX4, ACSL4, MDA, and ROS combination might have a good predictive value for DKD. Additionally, the course of disease, ferritin levels, serum iron, transferrin, and GPX4 were independently associated with massive proteinuria.

Low circulatory Fe and Se levels with a higher IL-6/IL-10 ratio provide nutritional immunity in tuberculosis.

Tuberculosis (TB) patients show dysregulated immunity, iron metabolism, and anemia. In this study, circulatory cytokines, trace metals, and iron-related proteins (hepcidin, ferroportin, transferrin, Dmt1, Nramp1, ferritin, ceruloplasmin, hemojuvelin, aconitase, and transferrin receptor) were monitored in case (active tuberculosis patients: ATB) and control (non-tuberculosis: NTB and healthy) study populations (n = 72, male: 100%, mean age, 42.94 years; range, 17-83 years). Using serum elemental and cytokine levels, a partial least square discriminate analysis model (PLS-DA) was built, which clustered ATB patients away from NTB and healthy controls. Based on the PLS-DA variable importance in projection (VIP) score and analysis of variance (ANOVA), 13 variables were selected as important biosignatures [IL-18, IL-10, IL-13, IFN-γ, TNF-α, IL-5, IL-12 (p70), IL-1β, copper, zinc, selenium, iron, and aluminum]. Interestingly, low iron and selenium levels and high copper and aluminum levels were observed in ATB subjects. Low circulatory levels of transferrin, ferroportin, and hemojuvelin with higher ferritin and ceruloplasmin levels observed in ATB subjects demonstrate an altered iron metabolism, which partially resolved upon 6 months of anti-TB therapy. The identified biosignature in TB patients demonstrated perturbed iron homeostasis with anemia of inflammation, which could be useful targets for the development of host-directed adjunct therapeutics.

Association of Serum Albumin, Globulin, and Transferrin Levels in Children of Poorly Managed Celiac Disease.

Celiac disease (CD) is an autoimmune genetic disorder in which gluten protein causes inflammation of the intestinal enterocytes. CD diagnosis in most cases is delayed or mistreated due to its varied clinical features. We aimed to evaluate the protein profile imbalance in different CD groups of children, which could help aid in the diagnosis and proper management of the disease. Methodology. This was a cross-sectional study with a nonrandom purposive sampling technique. All samples were taken from tertiary care hospitals of Hyderabad, Pakistan. In total, there were 175 children (age 3-15 years) divided into five equal groups (n = 35), namely, group A (control), group B (celiac diagnosed), group C (celiac-like symptoms), group D (celiac with type 1 diabetes mellitus), and group E (type 1 diabetes mellitus only). Clinical symptoms and laboratory parameters were analyzed among all the groups. Sera proteins, albumin, globulins, and transferrin levels were evaluated and compared with healthy individuals. The albumin in serum of celiac groups B and C was 3.0 g/dl and 2.8 g/dl, respectively. While in diabetic patients with CD, it is 2.7 g/dl. The globulin levels were raised among all the celiac groups with typical GIT symptoms. The highest transferrin was observed in group B, celiac patients with severe anemia. Patients were not on GFD, hence had no or less recovery and had chronic symptoms of celiac. The misdiagnosis and poor management of celiac leads to chronic villous atrophy with imbalance in metabolic profile. Serum analysis of albumin, globulins, and transferrin may help in the diagnosis and proper management of the disease to recover the celiac symptoms.

Physiological effect of iron status on patients with polycystic ovary syndrome in Basrah city.

Polycystic ovary syndrome (PCOS) is one of the most common gynecological diseases that affect the fertility in women in Basra governorate. The current study was designed in order to assess iron aberrations in PCOS patients by measuring the related parameters and their relationship with sex hormones in patients with PCOS. Serum samples were collected from 45 PCOS patients and 45 controls from a private women's clinic and were measured by ELISA in a private medical laboratory. The results showed a significant decrease in the level of hepcidin, transferrin and estradiol versus a significant increase in iron, ferritin, progesterone and testosterone. The current study showed a clear imbalance in the level of iron and its serum regulating parameters in in PCOS women, and there is an effective correlation between iron status and sex hormones.

The carbohydrate-deficient transferrin as a marker of chronic alcohol consumption and assessment of its usefulness in patients with cardiovascular diseases – a pilot study

Abstract Introduction Cardiovascular diseases (CVDs) are the leading cause of death in the world. The dose of 60 g of alcohol / day has been estimated to significantly increase the risk of developing high blood pressure, arrhythmias, hemorrhagic stroke, and cardiomyopathy. The aim of the study was to evaluate the diagnostic value of CDT when compared with gammaglutamyltransferase (GGT), alkaline phosphatase (ALP), N-terminal fragment brain natriuretic peptide (NT pro-BNP) and troponin T biomarkers in patients with heart failure. Materials and Methods The study was conducted on 59 patients with advanced heart failure with reduced ejection fraction (EF&lt;40%). CDT serum levels were measured using CDT kit, Chromsystems Instruments &amp; Chemicals GmbH, Germany and were expressed as a percentage of total transferrin using high-performance liquid chromatography (HPLC). Results Nineteen patients (n = 19) expressed a normal level of carbohydrate deficiency transferrin &lt;1.2% of the total transferrin found in plasma. The results are obtained from 34 patients (n = 34) were within the range doubtful for the test (1.2–2.5%). In 6 Patients (n = 6) the results of more than 2.5% of CDT content were observed, which could indicate chronic alcohol consumption. Conclusions No statistically significant correlations between CDT and troponin T or NT pro-BNP were identified.

Effects of Psychiatric Issues and Early Enteral Nutrition Therapy on Anxiety and Quality-of-Life of Patients with Gastric Cancer.

Objectives: In this study, we assessed the effects of psychiatric issues and early enteral nutrition therapy on anxiety and quality-of-life of patients with gastric cancer. Methods: We enrolled 60 patients with gastric cancer treated from January 2018 to November 2020 and divided them into 2 groups using a random number table (N=30 per group). All patients received early enteral nutrition therapy. The control group was given routine nursing; treatment of persons in the observation group was supplemented with additional psychiatric nursing. We then compared anxiety-depression scores, treatment compliance, nutritional status indices, and quality-of-life score. Results: The Self-rating Anxiety Scale (SAS) score and the Self-rating Depression Scale (SDS) score significantly declined in both groups after nursing compared with those before nursing (p<.05). After nursing, the SAS score and SDS score were lower in the observation group versus the control group (p<.05). The total rate of treatment compliance in the observation group (93.33%) was higher than that in the control group (73.33%) (p<.05). After nursing, the levels of hemoglobin, albumin, prealbumin, and transferrin were significantly higher in both groups than before nursing (p<.05), but higher in the observation group (p<.05). After nursing, the quality-of-life score was significantly higher in both groups than before nursing (p<.05), but higher in the observation group (p<.05). Conclusion: During enteral nutrition therapy for patients with gastric cancer, psychiatric treatment can effectively alleviate patient anxiety and depression, enhance treatment compliance, improve nutritional status, and enhance quality-of-life.

Лікування стрес індукованих розладів у жінок з лейоміомою матки на фоні гормонотерапії у військовий час

The purpose of the study was to assess psychosomatic changes and determine clinical and laboratory indicators in women with uterine fibroids under the conditions of using hormonal therapy and a drug with anxiolytic effect. Materials and methods. The study analyzed the results of 60 women with uterine fibroids who had anxiety disorder symptoms. The patients were divided into two groups: Group I – patients with uterine fibroids who took combined oral contraceptives (n=30); Group II – patients with uterine fibroids who took the anxiolytic medication fabomotizole concurrently with combined oral contraceptives (n=30). Results and discussion. The research established that patients with uterine fibroids had a change in their psycho-emotional state with a tendency to a high level of anxiety and depression. Treatment with combined oral contraceptives and fabomotizole demonstrated a more stable emotional background as compared to patients who took only combined oral contraceptives. The percentage of patients with the low level anxiety increased and the percentage of patients with the high level anxiety decreased. Among women who were treated with combined oral contraceptives only, there was still a considerable proportion of patients with high levels of anxiety and depression. It was found that the use of combined oral contraceptives in combination does not result in changes regrading the size of the tumor compared to the indicators of patients who did not take the drug with an anxiolytic effect. However, this group of patients demonstrated a tendency to stabilize the growth of nodes, to decrease clinical manifestations in the form of pain and intermenstrual bleeding in the first months of taking combined oral contraceptives. It should be noted that in patients who were not administered fabomotizole, the studied indicators remained at a lower level compared to the indicators of patients who were prescribed this drug. Probably, restoration of the psycho-emotional state in women with uterine fibroids under the influence of fabomotizole increases the effectiveness of hormonal therapy. Conclusion. The patients of both studied groups were shown to have developed pronounced anemia, which was confirmed by low values of hemoglobin in the blood, and the levels of ferritin and transferrin in the blood serum decreased. An increase in the studied indicators was observed after combined oral contraceptive treatment, and specifically after treatment with a combination of combined oral contraceptives and fabomotizole. However, the levels of ferritin and transferrin remained at a lower level compared to normal values

The Role of Vitamin B12 on Adenosine Monophosphate-activated Protein Kinase in Anemic Patients

Background: Anemia affects people at all stage of their lives, but it is most common in pregnant women and young children. Iron deficiencies are metabolic stress since it affects both the abilities to provide oxygen to tissue and the abilities to use oxygen (mitochondrial capability impairment). Vit.B12 plays role in the metabolism of AMP-activated protein kinase which considers as protection against inflammation in-vitro and in-vivo. Methodology: This study includes 30 samples of the patient and 30 samples as control groups, by centrifugation, blood samples were separated and stored at minus twenty centigrade. Different questions were asked of all patients and control groups. like duration of anemia, malabsorption, malnutrition, history, drugs, weight, height, and smoking Results: The results showed that the mean value of height levels in patients (162.2 ± 4.495 ) no significant difference (p-value = 0.6) as compared to control groups (165.6 ± 5.359) also in weight levels showed no significant difference (p-value = 0.9) between control (69.3 ± 3.418) and patients groups (63.8 ± 4.654). In vit.B12 levels, the mean value of patients (295.923 ± 162.241) showed a significant difference (p-value = 0.012*) as compared with mean of control groups (482.2 ± 158.12). In transferrin levels, there was a significant difference (p-value=0.04**) in vit.B12 levels between mean of patients (29.307 ± 11.604) and mean of control groups (42.4 ± 8.711). In addition to that, the mean value of Hb levels in patients (9.7 ± 2.200) showed significant difference (p-value = 0.03*) as compared to control groups (14.1 ± 0.94), finally, PCV levels showed a significant difference (P-value = 0.02*) in Polycythemia Vera (PCV) levels between mean of patients (43.3 ± 3.82) and mean of control groups (30.1 ± 6.601). Conclusion: In this study, further demonstrate that vit.B12 plays role to decrease inflammations by macrophage inhibition; we identify the mechanism of AMP pathway mediate vit.B12 action of anti-inflammations, and reported the relation between vit. B12 and AMP-activated protein kinase (AMPK) phosphorylation, therefore vit.B12 is considered as a novel action of anti-inflammatory reagent responses.

Nutritional Biomarkers and Heart Rate Variability in Patients with Subacute Stroke.

Malnutrition and autonomic dysfunction are associated with poor outcomes, mortality, and psychological problems after stroke. Relevant laboratory biomarkers include serum albumin, prealbumin, and transferrin. Heart rate variability (HRV), a noninvasive measurement, can objectively measure autonomic nervous system (ANS) function. The relationship between HRV and nutritional biomarkers in stroke patients has not been studied. This study aimed to examine the relationship between nutritional biomarkers and HRV parameters in stroke patients. We retrospectively recruited 426 patients with subacute stroke who were examined for nutritional biomarkers, such as serum albumin, prealbumin, and transferrin, and underwent 24 h ambulatory Holter electrocardiography. Patients were divided into groups according to their nutritional biomarker status. Differences in HRV parameters between nutritional biomarker-deficient and normal groups were assessed. Pearson's correlation and multiple regression analyses were used to verify the relationship between HRV parameters and nutritional biomarkers. HRV parameters were significantly lower in the nutritional biomarker-deficient groups. In addition, there was a significant association between HRV parameters and nutritional biomarkers. Serum albumin, prealbumin, and transferrin levels were associated with ANS function, as measured by HRV, and their deficiency may be a predictive factor for the severity of ANS dysfunction in stroke patients.

Beneficial effect of roxadustat on early posttransplant anemia and iron utilization in kidney transplant recipients: a retrospective comparative cohort study.

Although posttransplant anemia (PTA) is a common complication after kidney transplant, it has not been thoroughly evaluated for appropriate treatment. Roxadustat can stimulate erythropoiesis by increasing erythropoietin (EPO) production and improving the utilization of iron. However, there are currently a few case reports describing its effect on PTA in kidney transplant recipients (KTRs). Our purpose was to evaluate the efficacy and safety of roxadustat in KTRs with PTA. In this retrospective study, KTRs with early PTA were divided into a roxadustat group, erythropoiesis-stimulating agent (ESA) group, and untreated group (neither roxadustat nor ESA) according to the treatment prescribed by their physicians. We compared the levels of hemoglobin (Hb), creatinine, lipids, hepcidin, intact fibroblast growth factor 23 (iFGF23) and iron-related indices, at baseline and different time points posttransplant. Outcome was assessed at both month 3 and month 12 posttransplant. Adverse events during the treatment course were also recorded. A total of 57 KTRs were included (n=22 roxadustat group, n=13 ESA group, n=22 untreated group). There was no difference in age, sex, body mass index, dialysis method and duration, donor type among three groups at baseline. The mean Hb levels at month 3 posttransplant (128.00±19.62 vs. 118.59±11.60 g/L, P=0.048) and the average change in Hb levels from week 2 to month 3 (48.05±22.53 vs. 31.45±12.96 g/L, P=0.005) in the roxadustat group were significantly higher than those in the untreated group. However, there was no significant difference in the above indices between the roxadustat and ESA groups. At month 3, the total iron binding capacity (TIBC) and levels of transferrin were significantly higher while levels of ferritin, hepcidin and iFGF23 were significantly lower in the roxadustat group than in other groups (P<0.05). No significant difference was found in creatinine or estimated glomerular filtration rate (eGFR) levels among the three groups at month 3. During the follow-up, no adverse events related to roxadustat were reported. Administration of roxadustat in KTRs with early PTA could elevate Hb levels effectively and safely by enhancing endogenous EPO production and improving iron utilization. Further randomized studies with larger sample size are necessary to verify our results.
