Abstract
A serum ferritin level <15 to 20 μg/L historically identified patients who had absent bone marrow iron stores, but serum ferritin levels are distorted by the systemic inflammatory states seen in patients with chronic kidney disease or heart failure. As a result, nearly 25 years ago, the diagnostic ferritin threshold was increased 5- to 20-fold in patients with chronic kidney disease (ie, iron deficiency was identified if the serum ferritin level was <100 μg/L, regardless of transferrin saturation [TSAT], or 100 to 299 μg/L if TSAT was <20%). This guidance was motivated not by the findings of studies of total body or tissue iron depletion, but by a desire to encourage the use of iron supplements to potentiate the response to erythropoiesis-stimulating agents in patients with renal anemia. However, in patients with heart failure, this definition does not reliably identify patients with an absolute or functional iron-deficiency state, and it includes individuals with TSATs (≥20%) and serum ferritin levels in the normal range (20-100 mg/L) who are not iron deficient, have an excellent prognosis, and do not respond favorably to iron therapy. Furthermore, serum ferritin levels may be distorted by the use of both neprilysin and sodium-glucose cotransporter 2 inhibitors, both of which may act to mobilize endogenous iron stores. The most evidence-based and trial-tested definition of iron deficiency is the presence of hypoferremia, as reflected by as a TSAT <20%. These hypoferremic patients are generally iron deficient on bone marrow examination, and after intravenous iron therapy, they exhibit an improvement in exercise tolerance and functional capacity (when meaningfully impaired) and show the most marked reduction (ie, 20%-30%) in the risk of cardiovascular death or total heart failure hospitalizations. Therefore, we propose that the current ferritin-driven definition of iron deficiency in heart failure should be abandoned and that a definition based on hypoferremia (TSAT <20%) should be adopted.

Association between Iron Deficiency and Survival in Older Patients with Cancer. Cancers (Basel) 2023; 15:cancers15051533. [PMID: 36900329 PMCID: PMC10000607 DOI: 10.3390/cancers15051533] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Revised: 02/22/2023] [Accepted: 02/26/2023] [Indexed: 03/04/2023] Open
Abstract
BACKGROUND iron deficiency (ID) is frequent in older patients. PURPOSE to evaluate the association between ID and survival in patients ≥ 75 years old with confirmed solid tumors. METHODS a retrospective monocentric study including patients between 2009 and 2018. ID, absolute ID (AID) and functional ID (FID) were defined according to the European Society for Medical Oncology (ESMO) criteria. Severe ID was defined by a ferritin level < 30 µg/L. RESULTS in total, 556 patients were included, the mean age was 82 (±4.6) years, 56% were male, the most frequent cancer was colon cancer (19%, n = 104), and metastatic cancers were found in 38% (n = 211). Median follow-up time: 484 [190-1377] days. In anemic patients, ID and FID were independently associated with an increased risk of mortality (respectively, HR 1.51; p = 0.0065 and HR 1.73; p = 0.0007). In non-anemic patients, FID was independently associated with better survival (HR 0.65; p = 0.0495). CONCLUSION in our study, ID was significantly associated with survival, and with better survival for patients without anemia. These results suggest that attention should be paid to the iron status in older patients with tumors and raise questions about the prognostic value of iron supplementation for iron-deficient patients without anemia.

Abstract
Purpose of review To describe the role of iron deficiency in both heart failure and pulmonary hypertension. Recent findings To role of iron deficiency in heart failure is well established and pathophysiologic overlap with pulmonary hypertension exists. Summary Iron deficiency is common co-morbidity in heart failure and pulmonary hypertension. The high prevalence is intertwined into the pathophysiology of these conditions (e.g., neurohormonal activation, inflammation). The presence of iron deficiency has a negative impact on cardiomyocytes and cardiac function, skeletal muscle function, and pulmonary vascular function. In heart failure data from over 2000 randomized patients with iron deficiency using a uniform diagnosis, have illustrated beneficial effects on functional status, quality of life, reverse cardiac remodeling, and heart failure admissions. While iron deficiency is recognized to be prevalent in pulmonary hypertension and associated with worse functional status, the absence of a uniform definition and the absence of large prospective randomized controlled trials with iron therapies limits the conclusions on the causal role of iron deficiency such as observed in heart failure.

Abstract
Over the past decade, the detrimental impact of iron deficiency in heart failure with reduced ejection fraction has become abundantly clear, showing a negative impact on functional status, quality of life, cardiac function and structure, exercise capacity and an increased risk of hospitalisation due to heart failure. Mechanistic studies have shown the impact of iron deficiency in altering mitochondrial function and negatively affecting the already altered cardiac energetics in heart failure with reduced ejection fraction. Such failing energetics form the basis of the alterations to cellular myocyte shortening, culminating in reduced systolic function and cardiac performance. The IRON-CRT trials show that ferric carboxymaltose is capable of improving cardiac structure and cardiac performance. This article discusses the effect of iron deficiency on cardiac function and structure and how it can be alleviated.

Abstract
Iron is an essential micronutrient for a myriad of physiological processes in the body beyond erythropoiesis. Iron deficiency (ID) is a common comorbidity in patients with heart failure (HF), with a prevalence reaching up to 59% even in non-anaemic patients. ID impairs exercise capacity, reduces the quality of life, increases hospitalisation rate and mortality risk regardless of anaemia. Intravenously correcting ID has emerged as a promising treatment in HF as it has been shown to alleviate symptoms, improve quality of life and exercise capacity and reduce hospitalisations. However, the pathophysiology of ID in HF remains poorly characterised. Recognition of ID in HF triggered more research with the aim to explain how correcting ID improves HF status as well as the underlying causes of ID in the first place. In the past few years, significant progress has been made in understanding iron homeostasis by characterising the role of the iron-regulating hormone hepcidin, the effects of ID on skeletal and cardiac myocytes, kidneys and the immune system. In this review, we summarise the current knowledge and recent advances in the pathophysiology of ID in heart failure, the deleterious systemic and cellular consequences of ID.

Abstract
Iron deficiency is a major heart failure co‐morbidity present in about 50% of patients with stable heart failure irrespective of the left ventricular function. Along with compromise of daily activities, it also increases patient morbidity and mortality, which is independent of anaemia. Several trials have established parenteral iron supplementation as an important complimentary therapy to improve patient well‐being and physical performance. Intravenous iron preparations, in the first‐line ferric carboxymaltose, demonstrated in previous clinical trials superior clinical effect in comparison with oral iron preparations, improving New York Heart Association functional class, 6 min walk test distance, peak oxygen consumption, and quality of life in patients with chronic heart failure. Beneficial effect of iron deficiency treatment on morbidity and mortality of heart failure patients is waiting for conformation in ongoing trials. Although the current guidelines for treatment of chronic and acute heart failure acknowledge importance of iron deficiency correction and recommend intravenous iron supplementation for its treatment, iron deficiency remains frequently undertreated and insufficiently diagnosed in setting of the chronic heart failure. This paper highlights the current state of the art in the pathophysiology of iron deficiency, associations with heart failure trajectory and outcome, and an overview of current guideline‐suggested treatment options.

Abstract
Anemia is a very common comorbidity in patients with heart failure (HF), affecting ∼30% of stable ambulatory patients and 50% patients with acute decompensated HF. Absolute or functional iron deficiency (ID) is seen in ∼50% patients with HF. Both of these comorbidities often coexist and are independently associated with increased mortality and hospitalizations. These findings led several investigators to test the hypotheses that treatment of anemia and ID in HF would improve symptoms and long-term outcomes. Small studies showed that erythropoiesis-stimulating agents (ESAs) improve subjective measures of HF. However, a large pivotal outcome trial found that the ESA darbepoetin alfa did not improve long-term outcomes in patients with HF with reduced ejection fraction and instead was associated with adverse effects. Studies using IV iron have had somewhat greater success, showing improvements in subjective and some objective measures of HF. However, more research is needed to establish the best treatment options for these high-risk patients. We present 5 common scenarios of patients with HF and anemia and describe our personal approach on how we might treat them based on objective evidence where available. An algorithm that offers guidance in regard to personalized therapy for such patients is also presented.

Abstract
AIMS In heart failure (HF) iron deficiency (ID) is frequently observed and represents a major mortality risk factor. Purpose of this study was to evaluate the correlation between mortality and ID in a cohort of 661 consecutive patients hospitalized for HF worsening. METHODS AND RESULTS Patients were grouped: (i)according to presence(+)/absence(-) of anaemia (A) and ID defined following World Health Organization (WHO) and European Society of Cardiology (ESC)-American College of Cardiology/American Heart Association/HF society of America (ACC/AHA/HFSA) definitions, respectively: Group A-ID- (n = 123), Group A+ID- (n = 80), Group A+ID+ (n = 247), and Group A-ID+ (n = 211); (ii) according to presence of absolute (serum ferritin < 100μg/L) and functional ID [ferritin between 100 and 300μg/L and transferrin saturation (TSAT) < 20%]; and (iii) according to TSAT <20% and ≥20%. Groups were not different for several clinical features but age, gender, kidney function, and chronic obstructive pulmonary disease. Average follow-up was 1.94 year (±420 days). Overall 5 years mortality rate was 29.5%. Only anaemia and functional ID but not ID as defined by guidelines showed an impact on prognosis. Transferrin saturation <20% (n = 360) patients showed worst prognosis compared to TSAT ≥20% (n = 301) patients. In addition, functional ID patients showed worse prognosis compared patients with ferritin <100μg/L and TSAT <20% or ≥20% likely due to more severe chronic inflammatory status [C-reactive protein, 7.4 (interquartile range 2.7-22.6) and 3.2 (1.4-8.7) mg/L, P < 0.0001 respectively]. CONCLUSION We confirmed that in HF anaemia is associated to a poor prognosis. Moreover, we showed that patients with TSAT <20% had worse prognosis compared to those with TSAT ≥20% but the composite of ferritin between 100 and 300 μg/L and TSAT <20% identifies HF patients with the poorest survival rate.

Abstract
Introduction: Heart failure decompensation can be triggered by many factors, including anemia. In cases of iron deficiency anemia or iron deficiency without anemia, endoscopic studies are recommended to rule out the presence of gastrointestinal neoplasms or other associated bleeding lesions. Objectives: The aims of this study were to (i) examine trends in the incidence, clinical characteristics, and in-hospital outcomes of patients hospitalized with heart failure from 2002 to 2017 who underwent esophagogastroduodenoscopy (EGD) and/or colonoscopy, and to (ii) identify factors associated with in-hospital mortality (IHM) among patients with heart failure who underwent an EGD and/or a colonoscopy. Methods: We conducted an observational retrospective epidemiological study using the Spanish National Hospital Discharge Database (SNHDD) between 2002 and 2017. We included hospitalizations of patients with a primary discharge diagnosis of heart failure. Cases were reviewed if there was an ICD-9-CM or ICD-10 procedure code for EGD or colonoscopy in any procedure field. Multivariable logistic regression models were constructed to identify predictors of IHM among HF patients who underwent an EGD or colonoscopy. Results: A total of 51,187 (1.32%) non-surgical patients hospitalized with heart failure underwent an EGD and another 72,076 (1.85%) patients had a colonoscopy during their admission. IHM was significantly higher in those who underwent an EGD than in those who underwent a red blood cell transfusion (OR 1.10; 95%CI 1.04–1.12). However, the use of colonoscopy seems to decrease the probability of IHM (OR 0.45; 95%CI 0.41–0.49). In patients who underwent a colonoscopy, older age seems to increase the probability of IHM. However, EGD was associated with a lower mortality (OR 0.60; 95% CI 0.55–0.64). Conclusion: In our study, a decrease in the number of gastroscopies was observed in relation to colonoscopy in patients with heart failure. The significant ageing of the hospitalized HF population seen over the course of the study could have contributed to this. Both procedures seemed to be associated with lower in-hospital mortality, but in the case of colonoscopy, the risk of in-hospital mortality was higher in elderly patients with heart failure and associated neoplasms. Colonoscopy and EGD seemed not to increase IHM in patients with heart failure.

Abstract
Anaemia is defined by WHO as Hb < 13.0 g/dL in male adults and <12.0 g/dL in female adults. It is a common comorbidity in patients of heart failure with both HFrEF and HFpEF. The incidence ranges between 30% and 50%, though in certain communities, it is likely to be higher still. Elderly age, severe heart failure, poor nutrition, and elevation of inflammatory markers are associated with a higher incidence of anaemia. However, the commonest contributing factor to anaemia in HF is iron deficiency. In a Canadian study of 12 065 patients, the incidence of absolute ID was 21% in anaemic patients. Many other western studies have also quoted incidences varying between 35% and 43%. The earlier attempts to improve outcomes by supplementation with Erythropoietic-stimulating factors were unsuccessful and resulted in a higher incidence of thrombotic events. Iron deficiency (ID) has emerged as an important factor in patients of HF, even in those without anaemia and worsens outcomes. It is defined as Ferritin levels below 100 mcg/L or 100-299 μg/L with transferrin saturation of <20%. Attempts to correct ID by oral supplementation have been unsuccessful as seen in IRON-HF and IRONOUT-HF trials. FAIR-HF and CONFIRM-HF conclusively established the role of IV Iron in improving exercise capacity and quality of life in patients with HFrEF. ESC guidelines have given a class IC indication for testing all heart failure patients for ID, and an IIaA recommendation for its correction by IV ferric carboxymaltose was found to be deficient. Ongoing trials will establish the role of IV iron in improving mortality and in HFpEF patients and in patients with acute heart failure.

Abstract
Background: Treatment with ferric carboxymaltose (FCM) is limited to 1 g during one administration, which is insufficient in patients with a higher body weight or low haemoglobin (Hb). As a consequence, under-dosing might be common in clinical practice, yet the consequences remain unstudied.Methods: We retrospectively assessed all HFrEF-patients with iron-deficiency (ferritin <100 µg/l or between 100 and 300 µg/l if TSAT < 20%) receiving treatment with FCM between 2015 and 2017. This time-frame was chosen as during this we used a 1-g FCM-regimen for all patients (unless Hb = 14-15 mg/dl, than 500 mg). We compared the actual given dose versus the calculated target dose (according to the SmPC, with the difference between both being the dose deficit). We assessed the impact of dose deficits on clinical and biochemical status after 12 weeks.Results: A total of 211 HFrEF patients were analysed. The actual given dose FCM was 918 ± 188 mg, while the calculated target dose was 1308 ± 470 mg. In 121(61%) patients, a standard dose of 1-g FCM resulted in a dose deficit, of whom 93 had a dose deficit of 500 mg and 35 had a dose deficit of 1000 mg. Follow-up was available in 81% of patients (median = 12 weeks). A dose deficit of 500 mg was associated with a 4.93 higher odds, while a dose deficit of 1000 mg was associated with a 7.78 higher odds of residual iron deficiency. After adjusting for baseline NYHA-class, a dose deficit was associated with less symptomatic improvement. During 442 ± 292 days of follow-up, 68 patients were readmitted with heart failure and 15 patients died. In an univariate model (but not in a multivariate model), a dose deficit was associated with adverse clinical outcome.Conclusion: A majority of HFrEF patients with iron deficiency require doses exceeding 1 g of FCM, and thus require follow-up appointments to correct a residual dose deficit. A residual dose deficit is associated with less functional and biochemical improvement.

Abstract
INTRODUCTION AND OBJECTIVES Treatment with intravenous iron in patients with heart failure (HF) and iron deficiency (ID) improves symptoms, however its impact on survival and safety is unknown. We aimed to evaluate the management of ID and anemia with intravenous iron in patients with HF and long-term safety of intravenous iron. METHODS We evaluated anemia and ID in patients with chronic HF at 3 university hospitals. Anemia was defined using the World Health Organization definition and ID was defined as ferritin <100 ug/L or a Transferrin Saturation <20% if ferritin between 100 and 299 ug/L. We assessed treatment with intravenous iron during follow-up and its association with mortality and HF hospitalizations using multivariate cox regression analysis. RESULTS We included 2,114 patients, median age 72 years and 57% had reduced left ventricular ejection fraction. ID was present in 55% and ID and anemia in 29%. Treatment with intravenous iron was used in 24% of patients with ID and 34% of patients with ID and anemia. In patients with ID, after multivariate adjustment, treatment with intravenous iron was associated with lower all-cause mortality: HR = 0.38 (0.28-0.56), lower cardiovascular mortality: HR = 0.34 (0.20-0.57) and no differences in HF hospitalizations: HR = 1.15 (0.88-1.50). Similar outcomes were found for patients with anemia and ID. CONCLUSIONS In a real-world cohort of patients with HF, treatment with intravenous iron was used in one third of patients with ID and anemia and appears safe in mid-term follow-up.

Abstract
Angelica Sinensis Radix (Danggui, DG) is one of the most commonly prescribed traditional Chinese medicines. The organic components include phthalides and phenolic acids. Meanwhile, inorganic elements play an important role in clinical effect. DG and its different parts have different effects. There is no relevant report on the analysis of organic compounds and inorganic elements among them. Therefore, ultra-high-performance liquid chromatography coupled with triple quadrupole mass spectrometry was developed for the simultaneous determination of 13 organic components (8 phthalides and 5 phenolic acids), and 8 inorganic elements were determined by inductively coupled plasma mass spectrometry. The contents of 32 samples were analyzed by orthogonal partial least squares discrimination analysis, hierarchical cluster analysis, and least-significant difference of one-way analysis of variance. The results showed that the differences were significant among DG and its different parts. 11 difference markers (Ca, Z-ligustilide, Mg, Mn, Fe, Na, K, Cu, Zn, coniferyl ferulate, and senkyunolide A) were obtained by variable importance for the project. These difference markers were some different among DG and its different parts, especially Z-ligustilide, coniferyl ferulate, Mg, Zn, the differences were significant. This study can provide a reference for DG research.

Abstract
Objectives Iron deficiency (ID), with or without anaemia (IDA), is an important comorbidity in people with chronic heart failure (HF), but the prevalence and significance in those admitted with HF is uncertain. We assessed the prevalence of ID or IDA in adults (age ≥21 years) hospitalised with a primary diagnosis of HF, and examined key metrics associated with these secondary diagnoses. Methods A retrospective cohort study of Hospital Episode Statistics describing all adults admitted to National Health Service (NHS) hospitals across England from April 2015 through March 2016 with primary diagnostic discharge coding as HF, with or without subsidiary coding for ID/IDA. Results 78 805 adults were admitted to 177 NHS hospitals with primary coding as HF: 26 530 (33.7%) with secondary coding for ID/IDA, and 52 275 (66.3%) without. Proportionately more patients coded ID/IDA were admitted as emergencies (94.8% vs 87.6%; p<0.0001). Tending to be older and female, they required a longer length of stay (15.8 vs 12.2 days; p<0.0001), with higher per capita costs (£3623 vs £2918; p<0.0001), the cumulative excess expenditure being £21.5 million. HF-related (8.2% vs 5.2%; p<0.0001) and all-cause readmission rates (25.8% vs 17.7%; p<0.05) at ≤30 days were greater in those with ID/IDA against those without, and they manifested a small but statistically significant increased inpatient mortality (13.5% v 12.9%; p=0.009). Conclusions For adults admitted to hospitals in England, principally with acute HF, ID/IDA are significant comorbidities and associated with adverse outcomes, both for affected individuals, and the health economy.

Martens P, Minten L, Dupont M, Mullens W. Prevalence of underlying gastrointestinal malignancies in iron-deficient heart failure. ESC Heart Fail 2018; 6:37-44. [PMID: 30415506 PMCID: PMC6351899 DOI: 10.1002/ehf2.12379] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2018] [Revised: 07/22/2018] [Accepted: 10/10/2018] [Indexed: 12/15/2022] Open
Abstract
Aims Anaemia and iron deficiency (ferritin level < 100 or 100–300 μg/L with transferrin saturation < 20%) are prevalent in heart failure. Mechanistically, iron deficiency is linked to poor intestinal uptake, increased intestinal loss, and chronic inflammation. However, the prevalence of underlying gastrointestinal malignancies is not established in iron‐deficient heart failure with or without anaemia. Methods and results Patients followed up in a single‐centre, heart failure database with baseline registration of haemoglobin and iron status were retrospectively evaluated. The proportion of patients undergoing upper and lower gastrointestinal endoscopy between inclusion and censoring was determined. Afterwards, the prevalence of biopsy that confirmed intestinal malignancies in relation to baseline iron and haemoglobin status was determined. Anaemia was defined as a haemoglobin level <12 g/dL, and iron deficiency according to the aforementioned criteria. Of the 1197 patients in the database, 699 (59%) patients underwent full endoscopic workup over a mean follow‐up of 50 ± 27 months. A total of 50 intestinal malignancies were identified (n = 42, 84%, in iron‐deficient vs. n = 8, 16%, non‐iron‐deficient patients; P < 0.001). The prevalence of intestinal malignancies was non‐statistically different in iron‐deficient patients with anaemia (n = 12/129, 9.3%) or without anaemia (n = 30/287, 10.5%; P = 0.551). The prevalence was much lower in patients without iron deficiency with anaemia (n = 5/83, 6%) or without anaemia (n = 3/200, 1.5%). In patients with iron deficiency but without anaemia (a group in which the role of endoscopic workup is less established), ferritin levels carried an inverse diagnostic capacity in detecting patients with an underlying malignancy (area under the curve = 0.741, P < 0.001). A ferritin level < 56 μg/L had the best acuity, detecting malignancies with a sensitivity of 80% and a specificity of 71%. Conclusions Endoscopic evaluation is warranted in heart failure patients with iron‐deficient anaemia given the high prevalence of underlying intestinal malignancies, as advised by gastroenterology guidelines. However, additional research is needed assessing the best approach to patients with iron deficiency without anaemia, given the high occurrence of intestinal malignancies in these patients. A lower ferritin level could potentially help stratify the need for an endoscopic workup in these patients.
