“…It has been suggested that Xe interacts with the immune system by preserving neutrophil and monocyte antibacterial capacity and modulation of inflammatory cytokines such as tumor necrosis factor-a and interleukin-6 in monocytes. 38,39 In the present study, Xe had no effect on the commonly monitored inflammatory marker CRP. We compared degree and timing of the individual CRP responses withdatafrommatchedchildren undergoing cooling only.…”

BACKGROUND AND OBJECTIVES: Therapeutic hypothermia has become standard of care in newborns with moderate and severe neonatal encephalopathy; however, additional interventions are needed. In experimental models, breathing xenon gas during cooling offers long-term additive neuroprotection. This is the first xenon feasibility study in cooled infants. Xenon is expensive, requiring a closed-circuit delivery system. METHODS: Cooled newborns with neonatal encephalopathy were eligible for this single-arm, dose-escalation study if clinically stable, under 18 hours of age and requiring less than 35% oxygen. Xenon duration increased stepwise from 3 to 18 hours in 14 subjects; 1 received 25% xenon and 13 received 50%. Respiratory, cardiovascular, neurologic (ie, amplitude-integrated EEG, seizures), and inflammatory (C-reactive protein) effects were examined. The effects of starting or stopping xenon rapidly or slowly were studied. Three matched control subjects per xenon treated subject were selected from our cooling database. Follow-up was at 18 months using mental developmental and physical developmental indexes of the Bayley Scales of Infant Development II. RESULTS: No adverse respiratory or cardiovascular effects, including post-extubation stridor, were seen. Xenon increased sedation and suppressed seizures and background electroencephalographic activity. Seizures sometimes occurred during rapid weaning of xenon but not during slow weaning. C-reactive protein levels were similar between groups. Hourly xenon consumption was 0.52 L. Three died, and 7 of 11 survivors had mental and physical developmental index scores ≥70 at follow-up. CONCLUSIONS: Breathing 50% xenon for up to 18 hours with 72 hours of cooling was feasible, with no adverse effects seen with 18 months' follow-up.

“…There is increasing evidence that these properties are mediated by inhibition of proinflammatory intracellular signal transduction pathways (17). Accordingly, it was demonstrated in animal models of LPS administration that the release of proinflammatory cytokines is markedly reduced by exposure to volatile anesthetics (5,18).…”

Abstract. The nuclear factor (NF)-κB/inhibitory (I)κB· pathway is one of the most important intracellular signal transduction pathways during inflammation which is induced by a variety of major early response cytokines. Recent studies suggest that volatile anesthetics interfere with inflammatory cytokine production through inhibition of intracellular signal transduction pathways. We, therefore, aimed to investigate the effects of the volatile anesthetics sevoflurane and isoflurane on NF-κB/IκB·-dependent intracellular signal transduction in human monocytic THP-1 cells induced by tumor necrosis factor-· (TNF-·) and production of interleukin-8 (IL-8) and downstream heme oxygenase-1 (HO-1). THP-1 cells, a human monocytic cell line, were used in an in vitro model which enables the exposure to volatile anesthetics. Using this model, THP-1 cells were subjected to sevoflurane or isoflurane exposure (1 MAC each) and were stimulated with TNF-· (50 or 100 ng/ml). Compared to untreated cells, expression of intracellular HO-1-protein and release of IL-8 into cell culture supernatants and corresponding mRNA expression were attenuated in THP-1 cells exposed to sevoflurane and isoflurane, respectively. Moreover, translocation of NF-κB and degradation of IκB· were markedly reduced by both anesthetics. Notably, under unstimulated conditions, exposure to sevoflurane induced a sustained upregulation of the IκB· content in THP-1 cells. We demonstrated inhibition of TNF-·-induced gene expression and release of IL-8 and HO-1 in human monocytic THP-1 cells exposed to both volatile anesthetics. This was associated with an upregulated intracellular IκB· content followed by decreased NF-κB translocation. This was more sustained during exposure to sevoflurane and may provide an additional intracellular mechanism for the anti-inflammatory effects associated with sevoflurane administration.

“…In vitro investigations suggest that xenon has pro-inflammatory effects, increasing TNF-α and IL-6 [66], and IL-1β [67] in LPSmediated cultures. A recent study on adults did not show any differences in leucocyte function in peripheral blood with xenon compared to sevoflurane [63].…”

Cytokines are essential mediators for the regulation of both innate and acquired immunity and hematopoiesis. They modulate immune cell signaling, activation, adhesion and functioning. They regulate the individual response to several insults such as infection, inflammation, trauma, and pain. Moreover, the balance between pro-inflammatory and anti-inflammatory cytokines is critical for the evolution of surgical complications and tumor progression.Several drugs, including anesthetic agents, influence cytokines secretion. Opioids, inhalational agents, intravenous and local anesthetics have shown different effects on immune system and cytokine expression. Therefore, anesthesia may play an important role in postoperative recovery and outcome of cancer patients.The aim of the present article is to review the main role of some important cytokines and the effect of anesthesia techniques and drugs on their secretion. Furthermore, current clinical evidence regarding the effects of anesthesia on cancer recurrence will be discussed. Cytokines and immune systemCytokines are proteins expressed in both innate and acquired immune system and are often named according to the secreting cells (i.e., lymphocytes, interleukins, etc.). They are essential mediators of the natural (non-specific, innate) immunity, which is the initial step of the inflammatory response. They also play a pivotal role during the specific immunity, which occurs after exposure to antigens, as they regulate lymphocyte and leukocyte activation, growth and differentiation, and the immune-mediated inflammation [1].The cytokines have different structures, but also common aspects, which are summarized in Table 1.The aim of the present article is to review the main role of some important cytokines and the effect of anesthesia techniques and drugs on their secretion. Cytokines receptorsThe cytokines receptors are formed by one or more transmembrane proteins: the extracellular portion binds the cytokine, whereas the cytoplasmic part starts the signal cascade. Based on the extracellular portion, they are divided in five categories. 1) Type I receptors, which have four α-helical stands and contain four cysteine residues and the amino acid motif tryptophanserine-X-tryptophan-serine (WSXWS).2) Type II receptors, structurally similar to Type I receptors, but without the sequence WSXWS. Cytokines functionProvided that the same cytokine may be produced during both innate and acquired immunity response, cytokines can be classified according to their functions: 1)Cytokines regulating the innate immunity and secreted by stimulated macrophages; 2)Cytokines regulating the acquired immunity and secreted by lymphocytes; 3)Cytokines stimulating the hematopoiesiss and secreted by bone marrow, leucocytes and other cells. Common aspects of CytokineTheir secretion is brief and limited in time Cytokine expressed during the innate immunity response Tumor necrosis factor (TNF-α, TNF-β)The TNF is responsible for the initial phase of acute inflammatory response, especially against ...
