| Abstract | |
The cachexia associated with cancer, whose most notable symptom is severe and rapid weight loss, affecting about 80% of patients with cancer and avacado is the direct cause of death in 22 to 40% of cases. Recent studies have shown that inflammatory mediators play an important role in the development of cachexia, nowadays considered as a chronic inflammatory disease. A possible contributory is white adipose tissue (TAB) that undergoes various changes, such as morphological reorganization and increased lipolysis, thereby releasing free fatty acids (AGL), which in turn, can enhance the production of pro-inflammatory cytokines. The aim of this study was to analyse the gene expression of proinflammatory cytokines in the TAB and establish whether the fatty acids are released by fat cells in the presence of cachexia trigger and / or contribute to local and systemic inflammation. The study involved 122 patients divided into 3 groups: control (N) without cancer cachexia (WSC) and cancer cachexia (CC). The CC group consisted of patients with a loss of unintentional weight more than 5% in the last 12 months and met at least three of the five criteria used for classification of cachexia and the WSC group was composed of patients on treatment for cancer without declaring weight loss> 5% in the last 12 months. The subcutaneous adipose tissue (TASC) showed an increase in TNF- and increase the tendency of gene expression for CCL-2 gene expression in the CC as compared to N, while the mRNA content of IL-10 decreased in the same group. We suggest that the TASC is ignited in patients with cachexia associated with cancer and possible activator of secretion of proinflammatory proteins that fabric could be increased presence of free fatty acids.
