SUMMARY:

Obesity is characterized by a mass expansion of adipose tissue and changes in its body distribution, associated with a chronic increase in circulating concentrations of inflammatory mediators. Anti-inflammatory agents are presented as an alternative treatment for obesity, being tested in animal and human models. However, the lack of effective agents points to the need to assess the mechanisms and identify more effective therapeutic targets. This study aimed to gather similar studies published in the literature through a systematic review, aiming to answer the following question: "What are the mechanisms of action of anti-inflammatory agents in adipose tissue?". In addition to evaluating through evidence in a secondary study, new treatment pathways focused on inflammation and common in obesity and its conformities. Initially, a protocol for obtaining a systematic review was prepared and registered in the International Prospective Registry of Systematic Reviews (PROSPERO), aiming at guiding the secondary study. In this way, were used select report items for systematic review and meta-analysis protocols (PRISMA-P) to outline the protocol and PRISMA for systematic review and meta-analysis. The articles were selected according to eligibility criteria based on the PICOS (population, interventions, control, results, and study type). The databases used for the research were PubMed, ScienceDirect, Scopus, Web of Science, BVS, and EMBASE. Experimental studies using rats and mice with a control group that described treatment with anti-inflammatory drugs (drugs, nutraceuticals, bioactive compounds, among others) were included at any frequency, time, and dose. Three independent reviewers selected the articles and extracted the data. The evaluation of the methodological quality of each survey was carried out using the SYRCLE tool. The review protocol was registered with PROSPERO under the number: CRD42020182897 and published in a scientific journal. Initially, 1263 articles were selected, and at the end of the search, 27 were eligible for review. Among the anti-inflammatory agents, identified six drugs, 18 natural compounds, and three synthetic compounds. Given the studies, it can be inferred that a large part of the bioactive compounds, drugs, and synthetic compounds act in metabolic pathways that culminate, mainly, in the expression of inflammatory cytokines reduction, which favors an infiltration of macrophages reduction in white and adipose tissue. Besides, cause a polarization process of type M1 to M2 macrophages. It can be noted that innumerable inflammatory pathways overlap to explain the mechanism of action of these natural and synthetic compounds and drugs. Given the heterogeneity of the data, there was no grouping, and it was not possible to carry out the meta-analysis. Thus, the article clarifies and systematizes the mechanisms of these compounds and drugs in adipose tissue, being of great relevance and generating information for possible future research on these pathways, aiming at the most effective treatment of inflammation in obesity.
