Sepsis is a potentially fatal clinical condition that results from an immune imbalance in the host during an infection. It presents systemic alterations due to excessive activation of pro-inflammatory mediators that contribute to inflammation, formation of reactive species, and tissue damage. Anti-inflammatory mediators are then extensively activated to regulate this process, leading to immune exhaustion and, consequently, immunosuppression of the host. Considering the biological activities of the nutraceutical (), such as immunomodulatory, antioxidant, and antitumor activities, the present study investigated the therapeutic potential of the lipid fraction of (LF) in a model of lethal sepsis in mice (), induced by cecal ligation and perforation (CLP). The results showed that treatment of septic animals with LF or LF associated with ertapenem (LF-Erta) reduced systemic inflammation, promoting improvement in clinical parameters and increased survival. The data show a reduction in pro-inflammatory and oxidative stress markers, regulation of the anti-inflammatory response and oxidizing agents, and increased bacterial clearance in the peritoneal cavity and liver. Thus, it can be concluded that LF as a treatment, and in conjunction with antibiotic therapy, has shown promising effects as a hepatoprotective, antioxidant, antimicrobial, and immunomodulatory agent.
脓毒症是一种潜在致命的临床病症,它是由宿主在感染期间的免疫失衡引起的。由于促炎介质过度激活导致全身改变,这些促炎介质会引发炎症、活性物质形成和组织损伤。随后抗炎介质被广泛激活以调节这一过程,导致免疫耗竭,进而导致宿主免疫抑制。考虑到营养保健品()的生物活性,如免疫调节、抗氧化和抗肿瘤活性,本研究在由盲肠结扎和穿孔(CLP)诱导的小鼠致死性脓毒症模型()中研究了()脂质部分(LF)的治疗潜力。结果表明,用LF或与厄他培南联合使用的LF(LF-Erta)治疗脓毒症动物可减轻全身炎症,促进临床参数改善并提高生存率。数据显示促炎和氧化应激标志物减少,抗炎反应和氧化剂得到调节,腹腔和肝脏中的细菌清除增加。因此,可以得出结论,LF作为一种治疗方法,与抗生素疗法联合使用时,已显示出作为肝保护剂、抗氧化剂、抗菌剂和免疫调节剂的有前景的效果。
