Asprosin: Possible target in connection with ghrelin and cytokine network expression in the post-burn treatment.

Burn injury is a severe form of trauma associated with pain, metabolic abnormalities, susceptibility to infections, muscle loss, mental and emotional distress. Conventional therapies as well as some recent approaches for the treatment of burned patients are currently in use. Nutritional therapy is also suggested as a supplementary option in major burns. Within this context, hormones involved in the regulation of appetite will have a paramount importance. The aim is to evaluate the interactions among ghrelin, some inflammatory parameters and the burn injury. Asprosin is also involved into this discussion due to its ghrelin-like actions. Aside from the consideration of insulin as well as stress hormones (cortisol, epinephrine, norepinephrine), an orexigenic, anti-inflammatory hormone, ghrelin affecting both metabolic and inflammatory systems is also involved in the protocols designed for burn treatment. Ghrelin's actions exerted by way of growth-hormone secretagogue receptor, neuropeptide Y, agouti-related protein, proopiomelanocortin and gamma amino butyric acid are being investigated. Asprosin, one of the remarkably few hormones identified as appetite stimulator, acts as another orexigenic hormone by using almost the same signalling pathways as those of ghrelin. Interleukin-6 should also be evaluated both as a reliable biomarker of inflammation and also with its inhibitory effects on TNF-α within the scope of burn injury. In conclusion, treatment protocols during burn injury may be designed to raise decreased concentrations of ghrelin and to repress increased levels of inflammatory agents such as TNF-α. IL-6 may be evaluated from an entirely different aspect. The potential therapeutic use of asprosin may be considered within an integrative approach with a focus on cachexia-anorexia developed in severe burn trauma.
