Abstract

Context: The inflammatory state of the adipose tissue is believed to contribute to systemic low-grade inflammation in obesity. Objective: This study assessed the relationship between adipose and circulating inflammatory markers as well as the influence of adipose inflammation on bariatric surgery-induced weight reduction. Design: This was a cross-sectional and longitudinal study (up to 14 mo). Setting: The study was conducted in the digestive/bariatric surgery department of the Tivoli and Jean Villar clinics, Bordeaux, France. Patients: Thirty-seven obese patients [body mass index (BMI) > 35–40 kg/m2)] seeking bariatric surgery were included. Twenty-eight of them were successively followed up at 1–3 months after surgery and 25 between 6 and 14 months after surgery. Main Outcome Measures: Fasting serum samples were collected before surgery to assess concentrations of inflammatory markers. Samples of visceral adipose tissue were extracted during surgery and gene expression of cytokines and immune cell markers were evaluated using quantitative RT-PCR. Pre- and postsurgery weight and BMI were collected. Results: Gene expression of several cytokines were strongly intercorrelated in the visceral adipose tissue. Adipose expression of macrophage and T cell markers were related to adipose expression of TNF-α and IL-1 receptor antagonist (P < .01) and to systemic levels of TNF-α (P < .01) and IL-6 (P < .05). A higher inflammatory state of the adipose tissue predicted a lower BMI reduction after surgery (P < .05), notably at early stages after surgery. Conclusions: These findings support the involvement of macrophages and T cells in adipose inflammation and provide new information regarding the role of the visceral adipose tissue in the inflammatory state of obesity and its impact on obesity treatment outcomes, such as surgery-induced weight loss.

  • Inflammatory status is probably best defined by a combination of several cytokine concentrations rather than one cytokine only.

    “Given that the inflammatory status is probably best defined by a combination of several cytokine concentrations rather than one cytokine only, composite scores of inflammation were calculated using a standard method for identifying latent factors, i.e. Principal Component Analysis, which has been used in several previous studies (Hsu et al. 2009; Lasselin et al. 2012; Lasselin et al. 2014).”

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.
