Inappropriate expression of hepcidin is associated with iron refractory anemia: implications for the anemia of chronic disease

Abstract

The anemia of chronic disease is a prevalent, poorly understood condition that afflicts patients with a wide variety of diseases, including infections, malignancies, and rheumatologic disorders. It is characterized by a blunted erythropoietin response by erythroid precursors, decreased red blood cell survival, and a defect in iron absorption and macrophage iron retention, which interrupts iron delivery to erythroid precursor cells. We noted that patients with large hepatic adenomas had severe iron refractory anemia similar to that observed in anemia of chronic disease. This anemia resolved spontaneously after adenoma resection or liver transplantation. We investigated the role of the adenomas in the pathogenesis of the anemia and found that they produce inappropriately high levels of hepcidin mRNA. Hepcidin is a peptide hormone that has been implicated in controlling the release of iron from cells. We conclude that hepcidin plays a major, causative role in the anemia observed in our subgroup of patients with hepatic adenomas, and we speculate that it is important in the pathogenesis of the anemia of chronic disease in general.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Microcytosis occurs in longstanding severe inflammation such as in Castleman disease, a lymphoproliferative disorder in which high IL-6 production strongly enhances hepcidin synthesis, or in patients with ectopic hepcidin expression by liver adenomas.

  • Patients with glycogen storage disease type 1a and hepatic adenomas develop anemia resembling anemia of chronic disease, the severity of which correlates directly with the extent of tumor burden.

    “With Weinstein, Roy, and colleagues, we observed that these patients also develop anemia resembling the anemia of chronic disease, the severity of which correlates directly with the extent of tumor burden.100”

  • The hepatocyte-like cells of the adenomas expressed very high levels of hepcidin.

    “We found that the hepatocytelike cells of the adenomas expressed very high levels of hepcidin 100 and speculated that our results could be generalized-that induction of hepcidin expression in response to inflammation might explain the anemia of chronic disease.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
