Inflammatory markers and bariatric surgery: a meta-analysis

Rao, S. Raghavendra·2012·Inflammation Research

Abstract

Objective Obesity is a state of chronic low grade inflammation with increased levels of inflammatory markers such as C-reactive protein (CRP), interleukin (IL)-6 and tumor necrosis factor (TNF) α. The changes of some of the above markers after bariatric surgery are not consistent across studies. The objective of this study is to confirm the changes in blood levels of CRP, IL-6 and TNFα after bariatric surgery.Methods A Pubmed and EMBASE search was performed for studies measuring the above cytokines in blood before and after bariatric surgery. A meta-analysis was performed for the changes in CRP, TNFα and IL-6 for the maximum follow-up time in each study as well as for discrete follow-up times.Results Only observational studies could be retrieved. Bariatric surgery produces about 66 and 27 % reduction in CRP and IL-6 levels, respectively. The change in TNFα after bariatric surgery did not approach statistical significance.Conclusion Bariatric surgery decreases the low grade inflammation associated with obesity as measured by CRP and IL-6 levels. The change of TNFα after bariatric surgery should be further investigated with randomized trials.

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.
