Blood plasma toxins and inflammatory mediators

Blood plasma toxins and inflammatory mediators refer to a broad spectrum of pathogenic molecules that accumulate in the systemic circulation during acute and chronic disease states. This category encompasses pathogen-associated molecular patterns (PAMPs) like endotoxins, damage-associated molecular patterns (DAMPs), and a wide array of pro-inflammatory cytokines such as IL-1β, IL-6, and TNF-α [1][3]. These mediators are pivotal in driving the dysregulated host response seen in sepsis, cytokine release syndrome (CRS), and multi-organ dysfunction syndrome (MODS) [2]. From a therapeutic perspective, these substances are targeted either through specific pharmacological inhibition using monoclonal antibodies or through broad-spectrum extracorporeal removal techniques like hemoperfusion and high-cutoff hemodialysis [4][6]. The primary challenge in targeting this group lies in the double-edged sword nature of the immune response, where excessive removal may impair necessary host defense mechanisms or inadvertently clear essential medications [5]. Managing the levels of these toxins is crucial for stabilizing critically ill patients and preventing the progression of inflammatory cascades [6]. Sources: [1] Chousterman BG, et al. (2017).
