Abstract

Haemoglobin electrophoresis screening of 2341 infants from the oases of eastern Saudi Arabia, performed in an attempt to detect cases early and then to follow up and give better management to patients with sickle cell disease, showed 20% with S-trait and 43 with sickle cell disease (37 HbSS and 6 S-beta(0) thalassaemia). On follow-up from birth (or from 3 months) for a mean of 3 1/2 years there was more morbidity and mortality than in matched Saudi Arab controls, but these rates were lower than for affected black infants in the US or Jamaica. Serial haemoglobin levels were l g/dl lower than for controls; height and weight increases were the same. Mean fetal haemoglobin level was 32% at 4-5 years. Half of a subsample of 23 cases had evidence of coexistent alpha-thalassaemia which appeared to protect against functional asplenia, judged by the presence of Howell-Jolly bodies; however there was no difference in degree of anaemia or clinical course. Early screening is recommended for infants at risk for sickle cell disease, and comprehensive care should be given even if the infant has the less severe type.

  • When HbF is near 30%, disease can be relatively benign and 70% of cells can be protected.

    “When HbF is near 30%, disease can be relatively benign and 70% of cells can be protected.[52][53][54]”

    From Fetal hemoglobin in sickle cell anemia (2020) · cites this paper as [54]

    The Results report a mean HbF level of 29% in one group of Saudi Arab infants with HbSS, and the introductory passage says the unusually high HbF is believed to account for their relatively mild clinical course. The paper does not report that 70% of cells were protected; the Subjects and methods passage describes HbF distribution as heterocellular without giving a protected-cell percentage.

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.
