Bioavailability of iron and its potential to improve the immune system and ward off COVID-19: a review

Iron is a mineral that plays an important role, especially to prevent anaemia through the production of red blood cells. Iron also plays a role in physiological processes, such as the activation of enzymes and hormones, as well as increasing the immune system in warding off various viral infections. Therefore, iron bioavailability needs to be considered to take the greatest benefit of iron. This review discussed the factors that can affect the bioavailability of iron, various technologies to increase the bioavailability, and its potential in enhancing the immune system. Iron bioavailability can be increased by fortification, fermentation, the addition of vitamin C, and iron encapsulation. Under conditions of adequate iron intake, iron plays an important role in enhancing the immune system through controlling lymphocytes and T cell proliferation. However, excess iron consumption can be at risk of weakening the host's immune response to viruses. Therefore, the appropriate level of iron intake must be maintained accurately to be used optimally and has the potential to ward off viral infections, including the Sars-CoV-2 virus as the cause of COVID-19.Copyright © 2023, Rynnye Lyan Resources.

Double chelation of Iron through dimer formation of favipiravir: Density functional theory analysis

This work was performed to examine an idea about full chelation of Iron (Fe) by well-known favipiravir (Fav) as a possible mechanism of action for medication of COVID-19 patients. To this aim, formations of Fe- mediated dimers of Fav were investigated by performing density functional theory (DFT) computations of electronic and structural features for singular and dimer models. The results indicated that the models of dimers were suitable for formation, in which two cis (D1) and trans (D2) models were obtained regarding the configurations of two Fav counterparts towards each other. Energy results indicated that formation of D1 was slightly more favorable than formation of D2. Molecular orbital features affirmed hypothesized interacting sites of Fav for Fe-mediated dimers formations, in which atomic charges and other molecular orbital related representations affirmed such achievements. Moreover, detection of such dimer formation was also possible by monitoring variations of molecular orbitals features. As a consequence, formations of Fe-mediated dimers of Fav could be achievable for possible removal of excess of Fe as a proposed mechanism of action for Fav in medication of COVID-19 patients.

COVID-19-ASSOCIATED PULMONARY MUCORMYCOSIS PRESENTING AS SPONTANEOUS PNEUMOTHORAX: A RARE PRESENTATION

SESSION TITLE: COVID-19 Case Report Posters 1 SESSION TYPE: Case Report Posters PRESENTED ON: 10/17/2022 12:15 pm - 01:15 pm INTRODUCTION: Mucormycosis is an angio-invasive fungal infection with substantial morbidity and mortality. While diabetes and immune suppression remain well-known risk factors for mucormycosis, COVID-19 is now emerging as its independent predictor. CASE PRESENTATION: A 43-year-old male, with a history of hyperlipidemia and alcoholism, presented to the hospital with complaints of progressive dyspnea on exertion, productive cough, intermittent fever, anorexia, and chest pain over the course of 2 weeks. About 5 weeks prior to the current presentation, he was tested positive for COVID-19 by a polymerase chain reaction (PCR) based test and remained in quarantine at home. He was not vaccinated against COVID-19. He had no known immunosuppressive disease. On initial examination, he was ill-appearing and had a temperature of 101 F, blood pressure 138/83 mmHg, respiratory rate 22/minute, pulse 102/minute, and saturation of 91% on 2 L nasal cannula oxygen. A computerized tomography (CT) scan of the chest revealed small bilateral pneumothorax (2 cm and 5mm) along with extensive ground-glass opacifications in all lobes. In the next 24 hours, the right-sided pneumothorax progressed to tension pneumothorax requiring pigtail pleural drainage catheter placement. The drained pleural fluid had more than 100,000/uL total nucleated cells (91% neutrophils, 2% lymphocytes, and 1% eosinophils) and ultimately cultures grew Rhizopus spp. He was started on intravenous liposomal amphotericin-B infusion (5 mg/kg daily). On hospital discharge, he was switched to oral posaconazole (started with loading 300 mg delayed-release tablet twice a day, followed by 300 mg dosing of delayed-release posaconazole tablets daily) to complete the long term treatment course. DISCUSSION: Most of the reported cases of mucormycosis in COVID-19 were in patients with either diabetes or receiving steroids. This is a rare presentation of COVID-19–associated pulmonary mucormycosis (CAPM) as spontaneous pneumothorax, in the absence of known immunosuppression history. COVID-19 results in a considerable increase in cytokines, particularly interleukin-6 (IL-6), which increase free iron by increasing ferritin levels due to increased synthesis and decreased iron transport. Also, concomitant acidosis increases free iron by reducing the ability of transferrin to chelate iron and this available iron becomes a considerable resource for mucormycosis. [1] Also, Mucorales adheres to and invades endothelial cells by specific recognition of the host receptor glucose-regulator protein 78 (GRP-78). Acidosis associated with severe COVID-19 triggers GRP-78 and fungal ligand spore coating homolog (CotH) protein expression on endothelial cells, both contributing to angioinvasion, hematogenous dissemination, and tissue necrosis. [2] CONCLUSIONS: Mucormycosis can present as spontaneous pneumothorax after recent COVID-19 and clinicians should be aware of rare clinical presentation.

Bleomycin-Induced Lung Injury After Intravenous Iron Administration.

Bleomycin is an antibiotic that is often used as a chemotherapeutic agent due to its antitumor activities against a variety of malignancies. A feared and often fatal side effect of this drug is a pulmonary injury causing inflammation that can progress to pulmonary fibrosis. Bleomycin damages lung endothelial cells by the production of free radicals that can only occur when it is bound to certain metals in the body. It forms a complex with iron and once activated by iron reduction, it destroys deoxyribonucleic acid (DNA). Therefore, it is suggested that the availability of iron in the body may play a role in the pathogenesis of bleomycin toxicity although no related cases have been documented. This is a case of a 75-year-old female with no prior history of pulmonary disease who was diagnosed with Hodgkin's lymphoma and received 12 doses of bleomycin over the course of six cycles of chemotherapy. She then presented to the hospital with respiratory failure five months after her completion of treatment. Interestingly, one month prior to presentation, she was given two intravenous iron infusions of ferumoxytol five days apart for the treatment of iron deficiency anemia. Within a week of receiving the iron, she developed dyspnea with a nonproductive cough. About a month after she developed these symptoms, she presented to the hospital and was found to be hypoxic with any activity and was subsequently placed on oxygen via nasal cannula. Her lung imaging showed new reticulonodular and patchy infiltrates bilaterally concerning for pneumonitis and her physical examination was significant for black discoloration of her fingertips and toes along with expiratory rhonchi heard throughout her lungs. During the hospitalization, her oxygen requirements increased, and the patient ended up in the intensive care unit on bilevel positive airway pressure. Her lung imaging, rapid progression, and skin findings made the clinical diagnosis of bleomycin toxicity. Out of concern that the intravenous iron may have played a role in the toxicity, iron chelation was attempted. The patient was given two doses of deferoxamine over two consecutive days and her symptoms of dyspnea along with her oxygen requirements improved. Unfortunately, these positive effects only lasted a few days and the patient continued to decline and ultimately passed away. This case raises many questions regarding iron's role in bleomycin toxicity, including if intravenous iron infusions may increase the risk of pulmonary injury from bleomycin. There are currently no guidelines or recommendations that suggest withholding iron supplementation in patients undergoing chemotherapy with bleomycin. There is also insufficient evidence to support the routine use of iron chelation in a patient that presents with bleomycin-induced lung injury. However, some studies suggest that iron chelation may play a role in preventing pulmonary toxicity. It may also lessen the severity of the toxicity or improve some of the related symptoms, thus warranting further research.

Emerging Roles of the Iron Chelators in Inflammation.

Iron is a crucial element for mammalian cells, considering its intervention in several physiologic processes. Its homeostasis is finely regulated, and its alteration could be responsible for the onset of several disorders. Iron is closely related to inflammation; indeed, during inflammation high levels of interleukin-6 cause an increased production of hepcidin which induces a degradation of ferroportin. Ferroportin degradation leads to decreased iron efflux that culminates in elevated intracellular iron concentration and consequently iron toxicity in cells and tissues. Therefore, iron chelation could be considered a novel and useful therapeutic strategy in order to counteract the inflammation in several autoimmune and inflammatory diseases. Several iron chelators are already known to have anti-inflammatory effects, among them deferiprone, deferoxamine, deferasirox, and Dp44mT are noteworthy. Recently, eltrombopag has been reported to have an important role in reducing inflammation, acting both directly by chelating iron, and indirectly by modulating iron efflux. This review offers an overview of the possible novel biological effects of the iron chelators in inflammation, suggesting them as novel anti-inflammatory molecules.

Anti-Inflammatory Effects of the Iron Chelator, DIBI, in Experimental Acute Lung Injury.

Iron plays a critical role in the immune response to inflammation and infection due to its role in the catalysis of reactive oxygen species (ROS) through the Haber-Weiss and Fenton reactions. However, ROS overproduction can be harmful and damage healthy cells. Therefore, iron chelation represents an innovative pharmacological approach to limit excess ROS formation and the related pro-inflammatory mediator cascades. The present study was designed to investigate the impact of the iron chelator, DIBI, in an experimental model of LPS-induced acute lung injury (ALI). DIBI was administered intraperitoneally in the early and later stages of lung inflammation as determined by histopathological evaluation. We found that lung tissues showed significant injury, as well as increased NF-κB p65 activation and significantly elevated levels of various inflammatory mediators (LIX, CXCL2, CCL5, CXCL10, IL-1𝛽, IL-6) 4 h post ALI induction by LPS. Mice treated with DIBI (80 mg/kg) in the early stages (0 to 2 h) after LPS administration demonstrated a significant reduction of the histopathological damage score, reduced levels of NF-κB p65 activation, and reduced levels of inflammatory mediators. Intravital microscopy of the pulmonary microcirculation also showed a reduced number of adhering leukocytes and improved capillary perfusion with DIBI administration. Our findings support the conclusion that the iron chelator, DIBI, has beneficial anti-inflammatory effects in experimental ALI.

Post-COVID-19 Lymphocytopenia and Opportunistic Pathogens Infection in a Thalassemia Major Patient

Transfusion-dependent thalassemia patients undergo transfusion immunomodulating effects, which result in a general immune response depression and, consequently, an increase in the frequency of infectious episodes and neoplastic events due to a reduction in phagocytic function. Altered natural killer functions and IL-2-mediated lymphocytic response, defects in antigen presentation due to monocyte–macrophage cells, and decreases in bone marrow precursors and HLA II+ cells all play key roles in immunodepression in thalassemia major. SARS-CoV-2 infection presents marked lymphopenia, occurring in 96.1% of severe cases. COVID-19-related lymphopenia is due to various mechanisms, which lead to an increase in lymphocytic apoptosis. Post-COVID-19 lymphocytic quantitative and functional disorders may compromise immune response and promote the onset of infections via opportunistic pathogens. Herein, we report a case of a thalassemia major patient who developed severe post-COVID-19 lymphocytopenia, which may have facilitated the onset of a severe Klebsiella Pneumoniae infection.

A Phase 2a Study Evaluating the Safety and Pharmacokinetics (PK) of Luspatercept in Pediatric Patients with Transfusion-Dependent β-Thalassemia (TDT)

Background: β-thalassemia is an inherited hemoglobinopathy caused by mutations in the gene encoding the β-globin chain of hemoglobin (Hb), resulting in ineffective erythropoiesis, impaired red blood cell (RBC) maturation, and anemia. Patients (pts) with severe disease require regular, lifelong RBC transfusions and iron chelation therapy (ICT) shortly after diagnosis in early childhood. There is an unmet need for safe and effective treatments for pediatric pts to address the underlying pathophysiology of β-thalassemia and reduce the burden of chronic RBC transfusions early to prevent secondary iron overload and associated morbidity. Luspatercept is a first-in-class erythroid maturation agent approved in the USA and EU for the treatment of anemia in adult pts with β-thalassemia who require regular RBC transfusions. In previous studies, treatment with luspatercept resulted in clinically significant reductions in RBC transfusion burden in adults with TDT (phase 3 BELIEVE;Cappellini MD, et al. N Engl J Med 2020;382:1219-1231) and increased Hb levels in adults with non-TDT (phase 2 BEYOND study;Taher AT, et al. HemaSphere 2021;5[Suppl 2];S101). This phase 2a study (NCT04143724, EudraCT 2019-000208-13) will evaluate the safety and PK of luspatercept in pediatric pts with β-thalassemia who require regular RBC transfusions. The results will determine a recommended dose (RD) for each age group. Study Design and Methods: Eligible pts will be 6 to < 18 years of age;diagnosed with β-thalassemia, Hb E/β-thalassemia, or α-thalassemia/β-thalassemia;require ≥ 4 RBC units in the 24 weeks prior to enrollment (with no transfusion-free period ≥ 42 days and with a regular history of transfusions for ≥ 2 years);and have Karnofsky (≥ 16 years of age) or Lansky (< 16 years of age) performance status score ≥ 50 at baseline. Exclusion criteria include: a Hb S/β-thalassemia or α-thalassemia diagnosis, chronic anticoagulant therapy ≤ 28 days prior to enrollment, erythropoiesis-stimulating agent or hydroxyurea use ≤ 24 weeks prior to enrollment, ICT initiation ≤ 8 weeks prior to enrollment, use of any investigational drug ≤ 28 days prior to enrollment, or have undergone or are scheduled for transplant or gene therapy. A total of 54 pts will be enrolled in a staggered study design by age, beginning with a 12-week screening/run-in period. During Part A, pts 12 to < 18 years of age will receive luspatercept at 0.75 mg/kg (n = 6;Cohort 1) or 1.0 mg/kg (n = 6;Cohort 2) subcutaneously (s.c.) once every 21 days for ≤ 4 cycles (Figure A). The RD will be determined for each age group strata at the time of enrollment using descriptive statistics or frequency tabulations between and in aggregate across age-group arms. An expansion cohort (n = 30 pts 12 to < 18 years of age;Cohort 3) will then receive luspatercept for at least 1 year at the RD based on tolerability and safety data from Cohorts 1 and 2;if the RD is 1 mg/kg, titration up to 1.25 mg/kg is allowed in the expansion cohort based on erythroid response during the previous 2 dose cycles. Part B will be initiated following completion of Part A and review of overall safety data with the Data Monitoring Committee, Scientific Steering Committee, and health authorities. Pts 6 to < 12 years of age will be treated with luspatercept at 1.0 mg/kg (n = 6;Cohort 4) or 1.25 mg/kg (n = 6;Cohort 5) s.c. once every 21 days for ≤ 4 cycles (Figure B). Any pt who benefits from treatment can continue to receive luspatercept for ≤ 5 years from first dose and will be monitored for 5 years from first dose or 3 years from last dose, whichever occurs later. Pts may receive best supportive care, including RBC transfusions, ICT, antibiotics, antifungal or antiviral therapy, and/or nutritional support, as needed. The primary objectives are to determine the RD of luspatercept that is safe and tolerable and the PK of luspatercept in pediatric pts with TDT. Key secondary objectives include evaluating mean change in RBC transfusion burden, change in Hb levels, mean change in daily dose of ICT, mean change in serum ferritin, and the immunogenicity and safety of luspatercept in pediatric pts. Safety endpoints include evaluating the type, frequency, seriousness, and severity of adverse events and their relationship to luspatercept treatment. Exploratory endpoints include evaluating exposure-response, health-related quality of life, biomarkers/markers of iron overload and ineffective erythropoiesis, and SARS-CoV-2 serology.

Sickle Cell Disease and COVID-19 Infection: A Single-Center Experience

Background and Objectives: The COVID-19 (CO19) pandemic caused by SARS-CoV-2 remains a significant issue for global health, economics, and society. Several reports have shown that African Americans (AA) have been disproportionately affected by the CO19 pandemic. Limited data have suggested that sickle cell disease (SCD) could be one of the several reasons for higher morbidity and mortality related to CO19 among AA. Recent reports have suggested higher-than-average morbidity and mortality related to CO19 among patients with SCD. We conducted a retrospective, single-institution study in adult patients with SCD who were diagnosed with CO19 infection and their outcomes. Methods: After IRB approval, we conducted a chart review of adult patients (greater than 18 years) with SCD who were diagnosed with CO19 infection between March 1st, 2020, and March 31st, 2021. We recorded demographic data including age, gender, social factors (the type of insurance, availability of primary care provider (PCP), living alone/not), clinical parameters (type of SCD, co-morbidities), outpatient management of SCD, and how CO19 infection was managed like inpatient admission and complications. In patients who were admitted or seen in the emergency department (ED), we collected additional data including vitals, labs, the severity of illness, complications, length of stay, and outcomes. Computations were performed using statistical software SAS 9.4 for Windows. Results: We found a total of 51 patients with SCD diagnosed with CO19 infection in the above period. The median age of patients was 30 years. 61% were females and 39 % were males. All of them were AA. 11.76% were living alone, 49.02% were living with family, 1.96% (1 patient) was institutionalized, and the living situation was unknown in 37.25%. Most of the patients had Medicaid Insurance (52.94%), Medicare in 33.3%, private insurance in 13.73 % and 2% were uninsured. Only 64.71% of patients had a PCP. 60% had HbSS disease, 32% had HbSC disease, 4% had HbS-beta thalassemia, one patient each had HbSS with hereditary persistence of HbF and HbS/HbD. Comorbidities and previous history included acute chest syndrome in 65.96%, avascular necrosis in 36.96%, leg ulcers in 8.7%, hypertension in 8.7%, sickle cell retinopathy in 14.57%, cerebrovascular disease in 26.19%, chronic kidney disease in 7.69%, venous thromboembolism (VTE) in 20.41%, 10.41% were on anticoagulation, history of HIV and hepatitis C infection in 6.38%. 28.21% of patients were maintained on partial exchange transfusions as an outpatient for various indications. 72.73% were on hydroxyurea, 7.5% were on crizanlizumab, 5.26% were on voxelotor and 26.83% were on iron chelation. Vitals and pertinent lab values on initial assessment were recorded and many patients had missing data. On presentation, 25.53% were febrile, 29.17% of patients were tachycardic, 31.25% were hypoxic (SpO2 < 95%), 38.46% were tachypneic, 59.18% had a body mass index (BMI) of > 24.9. Median hemoglobin and hematocrit were 8.9/27.4 g/dL. The median white blood cell count was 9490/uL and platelets were 315,000/uL. Median ferritin was 1573 ug/L. Median bilirubin and creatinine were 2.05 mg/dL and 0.86 mg/dL. The patients were further stratified based on the clinical location where CO19 infection was managed (Table 1). 39.3% were diagnosed in the outpatient setting/ED and 60.3% in the inpatient setting. Among 51 patients, 5.71% (n=2) required ICU admission and was mechanically ventilated. 17.5% received dexamethasone, 7.69% received remdesivir, 2.76% received convalescent plasma, 17.07% had infections and 47% received antibiotics. Only one patient received an exchange transfusion during admission. One patient developed a new VTE after CO19 infection. On statistical analysis, the only factor which impacted the clinical location of management was tachycardia (P=0.007). Of the 51 patients, only 3.9% (2 patients) died of complications of CO19 infection, one with hypoxic respiratory failure, disseminated intravascular coagulation, shock, and the other one with pulmonary mbolism. 13% were readmitted within a month, one of them was admitted with a new pulmonary embolism and the others were admitted for acute painful episodes. Conclusion: We found a mortality rate of 3.9% in our single-center study of patients with SCD and CO19 infection. This mortality rate is lower than other published experiences in patients with SCD and CO19 infection.

COVID-19 and thalassemia beta major in splenectomized patient: Clinical case progression and literature review.

Although the possibility of asymptomatic course for COVID-19 infection in splenectomized thalassemia beta major patients is present, screening them for COVID-19 is important as the progression is still not clear.

Role of Iron Chelation and Protease Inhibition of Natural Products on COVID-19 Infection.

Although the epidemic caused by SARS-CoV-2 callings for international attention to develop new effective therapeutics, no specific protocol is yet available, leaving patients to rely on general and supportive therapies. A range of respiratory diseases, including pulmonary fibrosis, have been associated with higher iron levels that may promote the course of viral infection. Recent studies have demonstrated that some natural components could act as the first barrier against viral injury by affecting iron metabolism. Moreover, a few recent studies have proposed the combination of protease inhibitors for therapeutic use against SARS-CoV-2 infection, highlighting the role of viral protease in virus infectivity. In this regard, this review focuses on the analysis, through literature and docking studies, of a number of natural products able to counteract SARS-CoV-2 infection, acting both as iron chelators and protease inhibitors.

Hyperferritinemia in patients with COVID-19: An opportunity for iron chelation?

Studies from China on COVID-19 revealed that nonsurvivors had cytokine storm with high IL-6 and hyperferritinemia. Iron liberated from necrotic cells may catalyze free radical production and amplify lipid peroxidation causing membrane dysfunction and multiorgan failure. Consequently, iron chelators have been successfully utilized in various experimental and clinical models of cytokine storm and multiorgan damage, such as in ischemia-reperfusion injury, sepsis, and infections. Since viral replication may be influenced by iron accumulation, iron chelation has been proven beneficial in a variety of viral infections, such as HIV-1, hepatitis B virus, Mengovirus, Marburg hemorrhagic fever, Enterovirus 71, and West Nile virus. In this commentary, we elaborate on the idea of considering iron chelation as a therapeutic modality in patients with severe COVID-19 infection. For critically ill patients in the ICU, intravenous deferoxamine would provide sufficient and rapid iron chelation to ameliorate cytokine storm, whereas in less severe cases an oral chelator could prevent the development of excessive inflammatory response.

Management of Hemoglobin Disorders During the COVID-19 Pandemic.

The coronavirus disease 2019 (COVID-19) is an emerging infectious disease that has become a global public health concern after being first reported in China and has subsequently spread worldwide. It causes mild to severe respiratory illness with some flu-like symptoms. The causal virus behind this disease, SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), conceivably attacks the receptors of the respiratory system of the human body but has no strict evidence of attacking the blood cells yet. However, patients with hemoglobin disorders (e.g., sickle cell anemia, thalassemia) are vulnerable to this global health situation due to their clinical complications. Such patients are generally more prone to viral and bacterial infections, which can worsen their physical condition. Some of these patients present immunocompromised conditions, e.g., splenectomized or post-transplant patients. Therefore, they should follow some preventive steps such as shielding as well as the general guidelines for the COVID-19 pandemic. Transfusion dependent patients require regular monitoring for iron overload, and iron chelation therapy may be stopped by the physician depending on the situation. This article reviews the management strategies and provides some crucial recommendations for people in the corner with hemoglobin disorders.
