Abstract

The wide range of phenotypic abnormalities seen in the leptin-deficient ob/ob mouse and their reversibility by leptin administration provide compelling evidence for the existence of multiple physiological functions of this hormone in rodents.In contrast, information regarding the roles of this hormone in humans is limited.Three morbidly obese children, who were congenitally deficient in leptin, were treated with daily subcutaneous injections of recombinant human leptin for up to 4 years with sustained, beneficial effects on appetite, fat mass, hyperinsulinemia, and hyperlipidemia.Leptin therapy resulted in a rapid and sustained increase in plasma thyroid hormone levels and, through its age-dependent effects on gonadotropin secretion, facilitated appropriately timed pubertal development.Leptin deficiency was associated with reduced numbers of circulating CD4 + T cells and impaired T cell proliferation and cytokine release, all of which were reversed by recombinant human leptin administration.The subcutaneous administration of recombinant human leptin has major and sustained beneficial effects on the multiple phenotypic abnormalities associated with congenital human leptin deficiency.

  • r-metHuLeptin administration has been found to increase FT4 and FT3 levels in leptin-deficient children and to reverse the decreased T3 and T4 levels in four subjects on a long-term hypocaloric diet.

    “Although r-metHuLeptin administration has been found to increase FT4 and FT3 levels in leptin-deficient children (34) and to reverse the decreased T3 and T4 levels in four subjects on a long-term hypocaloric diet (42)”
  • Immune function could be markedly improved with leptin replacement.

    “However, immune function could be markedly improved with leptin replacement (29,30).”

  • Leptin may increase circulating cytokine concentrations and regulate the T helper type 1 and 2 cell immune balance in states of congenital leptin deficiency and immune dysfunction.

    “Thus, leptin may increase circulating cytokine concentrations and regulate the T helper type 1 and 2 cell immune balance in states of congenital leptin deficiency and immune dysfunction, supporting a role for leptin in regulating immune function in these conditions (29,30).”

  • Children with congenital leptin deficiency given leptin have appropriately timed pubertal development.

    “These children, when given leptin, have an appropriately timed pubertal development (28,29).”

  • Leptin-deficient subjects respond dramatically to leptin administered in replacement doses, which induces markedly decreased appetite and food intake and results in a significant reduction in body weight.

    “These leptindeficient subjects respond in a dramatic fashion to leptin administered in replacement doses, which induces markedly decreased appetite and food intake and which in turn result in a significant reduction in body weight (28)(29)(30).”

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.
