Abstract

Congenital leptin deficiency is a rare, but treatable, cause of severe early-onset obesity. To date, two United Kingdom families of Pakistani origin carrying a frameshift/premature stop mutation, c.398delG (Delta133G), and one Turkish family carrying a missense mutation, c.313C>T (Arg(105)Trp), have been described. Affected subjects are homozygotes and manifest severe obesity and hyperphagia accompanied by metabolic, neuroendocrine, and immune dysfunction. The effects of recombinant leptin therapy have been reported in three children with the Delta133G mutation, and in all cases this has led to a dramatic resolution of clinical and biochemical abnormalities. We now report a Canadian child, of Pakistani origin but unrelated to the previously reported subjects, presenting with severe hyperphagia and obesity, who was found to be homozygous for the Delta133G mutation. In this child, 4 yr of therapy with sc injections of recombinant leptin provided additional evidence for the sustained beneficial effects of leptin replacement on fat mass, hyperinsulinemia, and hyperlipidemia. In addition, leptin administration corrected abnormal thyroid biochemistry and allowed the withdrawal of T(4) treatment, providing additional support for the role of leptin in the regulation of the human hypothalamic-pituitary-thyroid axis.

Claims other papers make about this one

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

  • Congenital leptin deficiency is characterized by obesity, excessive adipose tissue, moderate storage of ectopic fat, and moderate insulin resistance.

    “The second example is congenital leptin deficiency (18 -20), which is characterized by obesity, excessive adipose tissue, moderate storage of ectopic fat, and moderate insulin resistance.”
  • In congenital leptin deficiency, metabolic abnormalities of dyslipidemia, glucose intolerance, and steatosis, which are only mildly abnormal, are corrected by leptin therapy.

    “Metabolic abnormalities of dyslipidemia, glucose intolerance, and steatosis, which are only mildly abnormal, are also corrected by leptin therapy.”
  • In congenital leptin deficiency, leptin replacement therapy is highly effective in controlling appetite, reducing food intake, and reducing overall fat mass.

    “Here, leptin replacement therapy is highly effective in controlling appetite, reducing food intake, and reducing overall fat mass.”

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.
