BACKGROUND: Fanconi Anemia (FA) is a rare and heterogeneous genetic syndrome. It is associated with short stature, bone marrow failure, high predisposition to cancer, microcephaly and congenital malformation. Many genes have been associated with FA. Previously, two adult patients with biallelic pathogenic variant in Breast Cancer 1 gene (BRCA1) had been identified in Fanconi Anemia-like condition. CLINICAL REPORT: The proband was a 2.5 year-old girl with severe short stature, microcephaly, neurodevelopmental delay, congenital heart disease and dysmorphic features...

One-third of all patients with heart failure have anemia, and its presence is associated with more symptoms, increased rates of hospitalization, and mortality. The etiology of anemia is multifactorial, complex, and varies between patients. The most important factors leading to anemia in heart failure are inadequate erythropoietin production resulting from renal failure, intrinsic bone marrow defects, medication use, and nutritional deficiencies such as iron deficiency. Erythropoiesis-stimulating agents (ESAs) have been proven to successfully correct hemoglobin levels, albeit without significant improvement in clinical outcome...

Whether patients with severe aortic stenosis (AS) die because of AS-related causes is an important issue for the management of these patients. We used data from CURRENT AS registry, a Japanese multicenter registry, to assess the causes of death in severe AS patients and to identify the factors associated with non-cardiac mortality. We enrolled 3815 consecutive patients with a median follow-up of 1176 days; the 1449 overall deaths comprised 802 (55.3%) from cardiac and 647 (44.7%) from non-cardiac causes. Heart failure (HF) (25...

Since the inception of the Canadian Cardiovascular Society heart failure (HF) guidelines in 2006, much has changed in the care for patients with HF. Over the past decade, the HF Guidelines Committee has published regular updates. However, because of the major changes that have occurred, the Guidelines Committee believes that a comprehensive reassessment of the HF management recommendations is presently needed, with a view to producing a full and complete set of updated guidelines. The primary and secondary Canadian Cardiovascular Society HF panel members as well as external experts have reviewed clinically relevant literature to provide guidance for the practicing clinician...

Anemia was shown to be associated with increased risk for adverse events in patients with heart failure (HF). However, there are limited data on the association between anemia and the risk for ventricular arrhythmias (VAs) in patients with an implantable cardioverter defibrillator (ICD). The present study population comprised 2,352 patients who were enrolled and prospectively followed up in the Israeli ICD Registry. The risk for a first appropriate ICD shock for VA was assessed by the presence of anemia, categorized at the lower tertile of hemoglobin distribution (≤12 g/dL [n = 753])...

A 35-year-old woman with fever, edema and rash was admitted. Pleural effusion and cardiomegaly were observed. A laboratory analysis revealed anemia with iron deficiency and elevated human parvovirus B19 (B19V) immunoglobulin M. The patient's hepcidin-25 and erythroferrone levels were not elevated compared to those observed later in her clinical course. On the other hand, her growth differentiation factor-15 (GDF-15) levels were elevated. She was diagnosed to have heart failure symptoms and anemia with specific iron metabolism abnormalities due to a B19V infection...

BACKGROUND: Clinical profiles of acute heart failure (AHF) complicating severe aortic stenosis (AS) remain unclear.Methods and Results:From a Japanese multicenter registry enrolling consecutive patients with severe AS, 3,813 patients were categorized into the 3 groups according to the symptom of heart failure (HF); No HF (n=2,210), chronic HF (CHF) (n=813) and AHF defined as hospitalized HF at enrolment (n=790). Median follow-up was 1,123 days with 93% follow-up rate at 2 years. Risk factors for developing AHF included age, female sex, lower body mass index, untreated coronary artery stenosis, anemia, history of HF, left ventricular ejection fraction <50%, presence of any combined valvular disease, peak aortic jet velocity ≥5 m/s and tricuspid regurgitation pressure gradient ≥40 mmHg, and negative risk factors included dyslipidemia, history of percutaneous coronary intervention and hemodialysis...

Diamond-Blackfan anemia (DBA) is a rare congenital erythroblastopenia and inherited bone marrow failure syndrome that affects approximately seven individuals in every million live births. In addition to anemia, about 50% of all DBA patients suffer from various physical malformations of the face, hands, heart, or urogenital region. The disorder is almost exclusively driven by haploinsufficient mutations in one of several ribosomal protein (RP) genes, although for ∼30% of diagnosed patients no mutation is found in any of the known DBA-linked genes...

OBJECTIVE: To consider the key implications of iron deficiency for biochemical and physiological functions beyond erythropoiesis. METHODS: PubMed was searched for relevant journal articles published up to August 2017. RESULTS: Anemia is the most well-recognized consequence of persisting iron deficiency, but various other unfavorable consequences can develop either before or concurrently with anemia. Mitochondrial function can be profoundly disturbed since iron is a cofactor for heme-containing enzymes and non-heme iron-containing enzymes in the mitochondrial electron transport chain...

Endothelial dysfunction is associated with decreased NO bioavailability and impaired activation of the NO receptor soluble guanylate cyclase (sGC) in the vasculature and in platelets. Red blood cells (RBCs) are known to produce NO under hypoxic and normoxic conditions; however evidence of expression and/or activity of sGC and downstream signaling pathway including phopshodiesterase (PDE)-5 and protein kinase G (PKG) in RBCs is still controversial. In the present study, we aimed to investigate whether RBCs carry a functional sGC signaling pathway and to address whether this pathway is compromised in coronary artery disease (CAD)...

The optimum method of managing anemia during the acute phase of acute heart failure (AHF) remains to be elucidated. The data from 1109 AHF patients were enrolled in present study. The hemoglobin (Hb) levels were evaluated in all patients at admission (day 1) and 3 days after admission (day 3), and in survival discharge patients (n = 998) before discharge (pre-discharge). The serum hemoglobin levels were significantly lower on day 3 (11.2 (9.6-12.9) g/dl) than on day 1 (12.4 (10.4-14.2) g/dl) and at pre-discharge (11...

Iron deficiency (FeD), with or without anemia, in adults with heart failure (HF) is associated with poor outcomes, which can be improved with replacement therapy. A similar therapeutic opportunity may exist for children; however, iron laboratory measurements and FeD have not been described in pediatric patients with HF. A single-center, retrospective study was conducted on 28 patients <21 years old with a diagnosis of dilated cardiomyopathy and HF who had iron laboratories (serum iron, iron saturation, and ferritin) performed...

There is evidence that serum iron levels, regardless of the presence of anemia, directly impact outcomes in congestive heart failure (CHF) including quality of life, hospitalization rate and overall survival. Despite modern medical treatments, the prognosis of CHF remains grim. Ironically, simple iron replenishment may serve as a powerful tool in the armamentarium. This review will start from fundamental concepts of iron in oxygen delivery and analyze evidence-based outcomes in CHF iron-directed therapeutic trials...
