Treating sickle cell disease by targeting HbS polymerization

Open access
Eaton, William A., Bunn, H. Franklin·2017·Blood

Abstract

Although the root cause of sickle cell disease is the polymerization of hemoglobin S (HbS) to form fibers that make red cells less flexible, most drugs currently being assessed in clinical trials are targeting the downstream sequelae of this primary event. Less attention has been devoted to investigation of the multiple ways in which fiber formation can be inhibited. In this article, we describe the molecular rationale for 5 distinct approaches to inhibiting polymerization and also discuss progress with the few antipolymerization drugs currently in clinical trials.

  • The most efficient means of treating sickle cell disease is interrupting disease pathophysiology by preventing deoxyHbS polymerization.

    “The most efficient means of treatment is interrupting disease pathophysiology by preventing deoxyHbS polymerization.”

    From Fetal hemoglobin in sickle cell anemia (2020) · cites this paper as [5]

    The Introduction (page unavailable) identifies HbS polymerization as the root cause of sickle cell pathology and argues for directing more research and trials toward inhibiting it. It does not establish that preventing polymerization is the most efficient treatment; the Conclusion (page unavailable) says polymerization inhibitors still face hurdles before clinical use. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Preventing deoxyHbS polymerization can be accomplished by inducing sufficiently high levels of HbF in most sickle erythrocytes.

    “This can be accomplished by inducing sufficiently high levels of HbF in most sickle erythrocytes.5”

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.
