Abstract
We are not entirely able to understand, assess, and modulate the functioning of the immune system in clinical situations that lead to a systemic inflammatory response. In the search for diagnostic and treatment strategies (which are still far from perfect), it became very important to study the pathogenesis and participation of endogenous inflammation mediators. This study attempts to more precisely establish the role of neutrophils in individual phenomena occurring during an inflammatory and anti-inflammatory reaction, taking into account their cidal, immunoregulatory, and reparative abilities. Pro- and anticoagulatory properties of endothelium in systemic inflammatory response syndrome (SIRS) are emphasised, along with the resulting clinical implications (the application of immunotherapy using mesenchymal stem/stromal cells (MSCs) or IL-6 antagonists in sepsis and COVID-19 treatment, among others). Special attention is paid to reactive oxygen species (ROS), produced by neutrophils activated during "respiratory burst" in the course of SIRS; the protective and pathogenic role of these endogenous mediators is highlighted. Moreover, clinically useful biomarkers of SIRS (neutrophil extracellular traps, cell-free DNA, DAMP, TREMs, NGAL, miRNA, selected cytokines, ROS, and recognised markers of endothelial damage from the group of adhesins by means of immunohistochemical techniques) related to the neutrophils are presented, and their role in the diagnosing and forecasting of sepsis, burn disease, and COVID-19 is emphasised. Finally, examples of immunomodulation of sepsis and antioxidative thermal injury therapy are presented.

[PMID: 37509519 PMCID: PMC10377452 DOI: 10.3390/biomedicines11071880] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 06/29/2023] [Accepted: 06/30/2023] [Indexed: 07/30/2023] Open
Abstract
Acute appendicitis is an inflammatory process which is one of the most frequent global causes of surgical interventions in children. The goal of the study was to determine whether acute phase proteins, that is, C-reactive protein (CRP), procalcitonin (PCT) and neutrophil gelatinase-associated lipocalin (NGAL), interleukin 6 (IL-6), transforming growth factor-beta1 (TGF-β1) and cortisol (HC) play a role in the pathomechanism of post-trauma stress response of the organism and to establish the impact of the applied surgical procedure and/or of inflammation on their concentrations. An additional purpose was to establish the clinical usefulness of the studied biomarkers in the diagnostics of appendicitis. CRP concentrations were quantified via the immunoturbidimetric method, while the levels of IL-6 and PCT were assessed using a bead-based multiplexed immunoassay system in a microplate format (Luminex xMAP technology); NGAL, TGF-β1 and cortisol concentrations were determined via the enzyme-linked immunosorbent assay (ELISA) technique. All the investigated biomarkers were assayed twice, i.e., immediately before the surgery and 12-24 h after its completion. Significant increases in CRP, IL-6 and PCT concentrations were found in all children subjected to laparoscopic surgeries (p = 0.001, p = 0.006, and p = 0.009, respectively) and open (classic) surgeries (p = 0.001, p = 0.016, and p = 0.044, respectively) compared to the initial concentrations. The patients undergoing classical surgery moreover presented with significant (p = 0.002, and p = 0.022, respectively) increases in NGAL and TGF-β1 levels after the procedures. In a group of children undergoing laparoscopic surgery, the appendicitis induced an increase in cortisol concentration, whereas in patients undergoing classical surgery the increase in the levels of this biomarker was caused by the type of performed surgical procedure. Simultaneously assaying the levels of CRP, NGAL and IL-6 (p = 0.008, p = 0.022, and p = 0.000, respectively) may prove useful in clinical practice, enabling the diagnosis of appendicitis in paediatric patients reporting to a hospital with abdominal pains, in addition to data from anamnesis and from clinical or ultrasound examination. The performed study confirms the participation of examined biomarkers in the pathomechanism of post-injury stress reaction of the organism to surgical trauma.

DISEASE MARKERS 2022; 2022:8779061. [PMID: 35664433 PMCID: PMC9162806 DOI: 10.1155/2022/8779061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/20/2021] [Revised: 02/28/2022] [Accepted: 03/29/2022] [Indexed: 12/03/2022]
Abstract
Objective To analyze the correlation of blood glucose level with inflammatory response and immune indicators in patients with sepsis. Methods Between February 2019 and February 2021, 30 sepsis patients and 30 sepsis patients complicated with diabetes mellitus admitted to our hospital were recruited and assigned to either the experimental group (sepsis patients) or the observation group (sepsis patients with diabetes mellitus). Another 30 healthy subjects in the same period were included as the control group. The levels of IL-6, TNF-α, IL-1β, CD4+, and CD8+ in the three groups of patients were compared to analyze the correlation of blood glucose levels with inflammatory response and immune indicators in patients with sepsis. The difference of counting data was analyzed using the chi-square test, and the difference of measurement data was analyzed using the t-test. Results The control group showed the lowest levels of IL-6 at 14.32 ± 4.98 pg/ml, followed by 18.33 ± 3.27 pg/ml in the experimental group and then 22.64 ± 5.16 pg/ml in the observation group (P < 0.05). The levels of other inflammatory factors including TNF-α and IL-1β were the lowest in the control group, followed by the experimental group, and then the observation group (P < 0.05). The lowest immune function indicator CD4+ and CD8+ levels were found in the observation group, followed by the experimental group, and then the control group (P < 0.05). The blood glucose level of patients with sepsis was positively correlated with the levels of IL-6, TNF-α, and IL-1β and was negatively correlated with the levels of CD4+/CD8+. The higher the blood glucose, the lower the number of immune cells. Conclusion The blood glucose level of patients with sepsis is positively correlated with inflammatory response and negatively with immune indicators. An increased blood sugar level is associated with aggravated inflammatory responses and a decreased number of immune cells, which provides a reference for the disease severity assessment and treatment of patients with sepsis.
