An iron scarcity often occurs in chronic kidney disease (CKD). Neutrophil gelatinase-associated lipocalin (NGAL), a biomarker of acute kidney injury, is associated with iron metabolism. The present study determined the association between serum NGAL and iron status in chronic kidney disease with anemia. A total of 154 adult CKD patients were divided into anemia and without anemia groups. The anemia groups were further subdivided into two groups based on the presence or absence of iron deficiency, defined as a transferrin saturation (TSAT) < 20%...

Blood transfusions in anemic patients frequently are used for critically ill patients as a life-saving therapeutic maneuver. Jehovah's Witness (JW) patients typically refuse blood transfusions due to religious beliefs. Numerous clinical reports, in a wide spectrum of medical specialties, have shown no greater morbidity or mortality in JW patients or others who refused transfusions compared to those patients who accept transfusions. We report our experience with two JW patients who presented with severe anemia and life-threatening pancreatitis...

BACKGROUND: Intrauterine transfusion for severe alloimmunization in pregnancy performed before 20 weeks' gestation is associated with a higher fetal death rate. Intravenous immunoglobulins may prevent hemolysis and could therefore be a non-invasive alternative for early transfusions. OBJECTIVE(S): We evaluated whether maternal treatment with intravenous immunoglobulins defers the development of severe fetal anemia and its consequences in a retrospective cohort to which 12 fetal therapy centers contributed...

SEC23B is a component of coat protein complex II (COPII) vesicles that transport secretory proteins from the endoplasmic reticulum (ER) to the Golgi apparatus. Loss-of-function SEC23B mutations cause a rare form of anemia, resulting from decreased SEC23B levels. We recently identified germline heterozygous SEC23B variants as potentially cancer-predisposing. Mutant SEC23B associated with ER stress-mediated tumorigenesis, without decreased SEC23B expression. However, our understanding of the processes behind these observations remain limited...

BACKGROUND: Iron deficiency (ID), with or without anemia, is frequent in heart failure patients, and iron supplementation improves patient condition. However, the link between ID (independently of anemia) and cardiac function is poorly understood, but could be explained by an impaired mitochondrial metabolism. Our aim was to explore this hypothesis in a mouse model. METHODS AND RESULTS: We developed a mouse model of ID without anemia, using a blood withdrawal followed by 3-weeks low iron diet...

BACKGROUND: Cold agglutinin disease is characterized by acrocyanosis, hemolytic anemia, and occasionally, frank hemoglobinuria. Although cold agglutinins are commonly detected, they are rarely clinically significant due to subphysiologic temperatures at which agglutination occurs. Cardiovascular surgical procedures requiring hypothermia present a unique challenge for these patients, requiring modification of the conduct of cardiopulmonary bypass and cardioplegia. CASE REPORT: Herein we report a case of a patient with a prior history of symptomatic cold agglutinin disease and type A aortic dissection, presenting with dilation of his known diseased ascending aorta, requiring semi-urgent repair...

OBJECTIVE: Sucroferric oxyhydroxide, a novel iron-based phosphate-binder, has been shown to have beneficial effects in lowering serum phosphorus levels and improving renal anemia in clinical studies. Although an effect of this agent on fibroblast growth factor 23 (FGF23) has been reported in an animal study, there is little clinical data supporting this finding. This study aimed to evaluate the effect on chronic kidney disease-mineral and bone disorder, FGF23, renal anemia, iron-related parameters, adverse events of sucroferric oxyhydroxide in hemodialysis patients...

One should always consider iron deficiency (without anemia) as the cause of persisting, unexplained unspecific, often severe, symptoms, regardless of the primary underlying disease. The symptoms of iron deficiency may arise from the metabolic systems where many proteins are iron containing. Long-standing iron deficiency may be challenging to treat.

BACKGROUND: There are racial, ethnic and geographical differences in complete blood count (CBC) reference intervals (RIs) and therefore it is necessary to establish RIs that are population specific. Several studies have been carried out in Africa to derive CBC RIs but many were not conducted with the rigor recommended for RI studies hence limiting the adoption and generalizability of the results. METHOD: By use of a Beckman Coulter ACT 5 DIFF CP analyser, we measured CBC parameters in samples collected from 528 healthy black African volunteers in a largely urban population...

PURPOSE: Pathogenic variations in genes encoding aminoacyl-tRNA synthetases (ARSs) are increasingly associated with human disease. Clinical features of autosomal recessive ARS deficiencies appear very diverse and without apparent logic. We searched for common clinical patterns to improve disease recognition, insight into pathophysiology, and clinical care. METHODS: Symptoms were analyzed in all patients with recessive ARS deficiencies reported in literature, supplemented with unreported patients evaluated in our hospital...
