Abstract

It has been suggested that elevated leptin levels underlie the low grade proinflammatory state in human obesity. We reasoned that if elevated leptin levels are an important factor in the proinflammatory state in obesity, then exogenous leptin administration during weight loss should counteract the concurrent beneficial effects of weight loss on the proinflammatory state. We therefore determined whether long-acting pegylated recombinant leptin (PEG-OB) prevents the decrease in cellular and humoral inflammation parameters during a very low calorie diet in healthy overweight young men. Except for B cells, PEG-OB treatment did not influence the decline in total leukocyte count and mononuclear subfractions during the diet. Weight loss decreased the humoral inflammation parameters TNFalpha, tissue plasminogen activator, and von Willebrand factor (P < 0.05), but in combination with PEG-OB treatment, a significant decrease was shown for inflammation markers as a whole (P < 0.014) and that of the individual parameters tissue plasminogen activator, von Willebrand factor, plasminogen activator inhibitor type 1, and intercellular adhesion molecule-1 (P < 0.05). The increase in C-reactive protein levels (P < 0.05) was the sole indication for a humoral proinflammatory action of leptin. Although PEG-OB treatment significantly increased weight loss (P < 0.03), the data do not support a proinflammatory role of leptin in human obesity.

  • Obesity and inflammation are significantly related.

    “considerable evidence suggests that obesity and inflammation are significantly related [163,486,575,581,642,647-664]”
  • Increased leptin levels contribute to oxidative stress by enhancing macrophages' phagocytic activity and inducing synthesis of pro-inflammatory cytokines (TNFα, IL-6, IL-2, and interferon-gamma) and secondarily increased level of endothelial cell dysfunction markers.

    “Recent studies have shown that increased leptin levels contribute to oxidative stress by enhancing macrophages’ phagocytic activity and inducing the synthesis of pro-inflammatory cytokines (TNFα, IL-6, IL-2, and interferon-gamma) and secondarily increased level of endothelial cell dysfunction markers [106,107].”

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.
