Abstract

To examine leptin’s role in human appetite regulation, we studied recombinant methionyl human leptin’s effects on satiation and satiety in a model of leptin insufficiency, lipodystrophy. Eight females with hypoleptinemia and lipodystrophy were given sc injections of A-100 (maximal dose, 200% of that predicted to normalize serum leptin) for 4 months. Satiation and satiety were determined before and again during leptin treatment. Satiation was measured as the time to voluntary cessation of eating from a standardized food array after a 12-h fast. Satiety was determined as the time to hunger sufficient to consume a full meal after consumption of a standardized preload. During leptin treatment, satiation time decreased (41.2 ± 18.2 to 19.5 ± 10.6 min; P = 0.01), satiety time increased (62.9 ± 64.8 to 137.8 ± 91.6 min; P = 0.04), energy consumed to produce satiation decreased (2034 ± 405 to 1135 ± 432 kcal or 8.5 ± 1.7 to 4.7 ± 1.8 MJ; P < 0.01), and the amount of food desired in the postabsorptive state decreased (P < 0.02). Ghrelin concentrations also decreased during leptin administration (284.3 ± 127.9 to 140.6 ± 104.5 pmol/liter; P < 0.002). We conclude that increased leptin in patients with lipodystrophy results in less caloric, shorter, more satiating meals and longer-lived satiety. These data support the hypothesis that leptin plays an important, permissive role in human appetite regulation.

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

  • When patients with lipodystrophy and reduced leptin were placed on r-metHuLeptin, they reported improved satiety and satiation, resulting in approximately 40% reduction of caloric intake.

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.
