Anemia of chronic disease (ACD) is the result of altered iron metabolism, blunted erythropoiesis, and shortened red blood cell survival caused by inflammatory cytokines. Hepcidin plays a key role in anemia of chronic disease by inducing endocytosis of the iron exporter ferroportin. Iron is trapped in enterocytes, hepatocytes, and macrophages, and is unavailable for hemoglobin synthesis. When treating the underlying disease is not an option, or anemia is severe, ACD should be treated. While oral iron supplementation is not suitable for ACD, intravenous iron may be effective. Erythropoiesis stimulating agents are a common approach to treating ACD, but a large …

Crohn’s disease and ulcerative colitis are the two most prevalent inflammatory bowel diseases (IBDs) in Jewish and Caucasian populations, affecting as many as one in 250 individuals. Nevertheless, the underlying causes of both disorders are not yet fully understood and remain unknown. However, current evidence suggests that the exaggerated inflammatory response, more commonly referred to as IBD, is believed to arise from dysregulation of the gastrointestinal (GI) immune system in genetically predisposed individuals who are exposed to environmental triggers. Recent advances have identified multiple IBD susceptibility genes; however, only a few environmental determinants of IBD have been consistently identified. The …
