Opis:: Adenoid is lymphoid tissues in the pharynx that play an important role in host defense against invading antigens. The structures of adenoid consist of well-defined microcompartments which all participate in the immune response: the lymphoepithelium, the follicular germinal center, the mantle zone, the interfollicular area. Otitis media with effusion (OME) is a common middle ear disease in children, but etiology of this disease is not clearly understood. Immunologic reaction within adenoid, pro-inflammatory cytokines (Th1 and Th2), decrease of lymphocytes T and B, metaloproteinase may lead to chronic infection.
Migdałek gardłowy wchodząc w skład obwodowych narządów limfatycznych jest miejscem pierwszego kontaktu z antygenami, docierającymi drogą oddechową i pokarmową. Migdałek gardłowy zawiera komórki aktywne immunologiczne niezbędne do odpowiedzi immunologicznej komórkowej oraz humoralnej. Komórki te zajmują trzy główne przedziały limfoidalne: limfonabłonek, grudkowe ośrodki rozmnażania wraz ze strefą osłonową tych ośrodków oraz przestrzeń międzygrudkowa. Wysiękowe zapalenie ucha środkowego (OME) jest częstą chorobą ucha środkowego występującą u dzieci. Jednak etiologia tej choroby nie jest do końca poznana. Reakcje immunologiczna toczące się w obrębie migdałka gardłowego, udział cytokin prozapalnych typu Th1 i Th2, limfocytów T i B oraz metaloproteinaz może prowadzić do przewlekłego zakażenia w obrębie ucha środkowego u dzieci.

Opis:: Introduction and aim. Coronavirus disease 2019 is characterised by cytokine storm and it was managed with repurposed drugs, however the effect of this treatment on cytokine storm is unknown. The aim of the study was to investigate the effect of repurposed management on serum Th1 pro-inflammation cytokine (IFN-γ) and Th2 anti-inflammation cytokine (IL-4) in COVID-19 patients. Material and methods. The levels of IFN-γ and IL-4 were determined in sera from 45 COVID-19 patients at admission followed-up till discharge after repurposed treatment using ELISA. The mean levels and proportions above normal reference ranges of IFN-γ and IL-4 were compared in COVID-19 at admission and discharge. Results. The mean values of IFN-γ and IL-4 were significantly higher in COVID-19 patients at admission compared with discharged COVID-19 patients whereas IFN-γ:IL-4 ratio was significantly higher in discharged COVID-19 patients compared with admitted COVID-19 patients. Significantly higher proportion of COVID-19 patients at discharge had IFN-γ within the normalreference ranges compared with COVID-19 patients at admission whereas the proportions of COVID-19 patients at discharge and COVID-19 patients at admission having IL-4 within the normal reference ranges were the same. Conclusion. Cytokine storm was evidenced in COVID-19 patients at admission and repurposed treatment suppressed pro-inflammation cytokine (IFN-γ) in most discharged COVID-19 patients.

Opis:: Cytokines are low molecular weight signaling proteins which have a complex regulatory influence on inflammation and the immune system T-cells response. In response to various stimuli, cytokines are secreted by different cells predominantly white blood cells. Regulation of immune homeostasis requires a balance between sufficient cytokine produ hey integrate functions of several cell types into a coherent immune action to eliminate the pathogen and avoidance of a hyperinflammatory response. Pyroptosis, oncosis and necroptosis are inflammatory, lytic forms of programmed cell death that protect against infections and can be triggered by pathogen and host molecules. Inflammation, complex response involving immune cells, blood vessels, and molecular mediators, is part of innate defense mechanisms and plays a role in the healing process. Beyond the innate and adaptive immunity, cytokines has a major role in cytokine storm. No single definition of cytokine storm or the cytokine release syndrome, is widely accepted. Cytokine storm is based on the elevated circulating cytokine levels, acute systemic inflammatory reactions and dysfunction. Cases can progress rapidly to disseminated intravascular coagulation with either vascular occlusion or catastrophic hemorrhages, dyspnea, hypoxia, hypotension, hemostatic imbalance, vasodilatory shock, and death. In this article, interdependence of these inflammatory mediators in a normal and a dysregulated response was presented.

Opis:: Aim: To investigate the effects of vacuum-assisted closure (VAC) vs. relaparotomy on demand (ROD) onto the i) severity and course of disease, ii) surgical outcome, iii) intraperitoneal bacterial load as well as iv) local/systemic inflammatory and immune response in postoperative secondary peritonitis. Methods: Over a defined time period, all consecutive patients of the reporting surgical department with a secondary peritonitis (assessed by Mannheim’s Peritonitis Index [MPI] and APPACHE II score) were enrolled in this systematic unicenter clinical prospective observational pilot study. Patients were subclassified into VAC or ROD group according to surgeon’s individual decision at the time point of primary surgical intervention with the intent to sanitize the source of infection. Early postoperative result was assessed by 30-d and in-hospital mortality. Bacterial load was characterized by microbiological culture of intraperitoneal fluid collection obtained on postoperative days (POD) 0 (primary surgical intervention), 1,4,7,10,13 and following description of the microbial spectrum including semiquantitative assessment of bacterial load. Local/systemic inflammatory and immune response was determined by ELISA-based analysis of CrP, PCT and the representative cytokines such as TNF-α/IL-1α/IL-6/IL-8/IL-10 of serum and peritoneal fluid samples. Results: Over a 26-month investigation period, 18 patients (male:female=9:9) were eligible for study criteria: n=8 were enrolled in the VAC and n=10 in the ROD group. With regard to early postoperative results represented by mortality, there is no significant difference between both patient groups. Despite the relatively low number of cases enrolled, a tendency for more severe findings associated with the VAC group could be detected based on the MPI score. There was also a tendency for higher APACHE II scores in the VAC group from the 7th POD on and, in addition, patients of this group had a longer hospital stay. For patients with persisting infection, there were no relevant differences comparing VAC therapy and ROD. Cytokines released in particular at the beginning of the inflammation cascade with proinflammatory characteristics showed higher values within the peritoneal fluid whereas CrP and PCT were found to be higher within the serum samples. Conclusion: Comparing data of various local/systemic inflammatory and immune parameters, there were only a few correlations. This may indicate compartmentation of the inflammatory process within the abdominal cavity. Based on the observed inter-individual variation of this pilot study data, the clinically applicable benefit appears questionable. In this context, reliable effects of VAC therapy on the reduction of bacterial burden within the abdominal cavity could not clearly be detected.

Opis:: Proces zapalny jest bezpośrednio związany z sekrecją cytokin, np. czynnika martwicy nowotworu alfa (ang. Tumor Necrosis Factor alpha; TNF-α). Ta cząsteczka jest 1 z 22 białek należących do rodziny TNF i wydzielana jest głównie przez: makrofagi, monocyty, limfocyty T oraz komórki tuczne. Biologiczne efekty działania TNF-α zachodzą dzięki wiązaniu się tej cytokiny ze specyficznymi dla niej receptorami – TNFR1 i TNFR2. Duża liczba prac potwierdza kluczową rolę TNF-α w nowotworzeniu i chorobach układu sercowo-naczyniowego, będących chorobami o podłożu prozapalnym. Niestety, mimo postępu medycyny i wzrostu świadomości społeczeństwa, wymienione choroby stanowią główne przyczyny śmierci na świecie. Lepsze zrozumienie roli tej cytokiny w kancerogenezie i chorobach zapalnych może spowodować wykorzystanie TNF-α jako markera tych chorób oraz do monitorowania przeciwzapalnych efektów terapii.
The inflammatory process is directly associated with secretion of cytokines, e.g. tumor necrosis factor alpha (TNF-α). This molecule is one of the 22 proteins which belong to TNF family and is secreted mainly by: macrophages, monocytes, T lymphocyte and mast cells. The biological effects of TNF-α is possible through binding this cytokine to specific receptors – TNFR1 and TNFR2. The large number of reports provides that this cytokine plays extremely important role in cancers and cardiovascular disease – two groups of inflammatory diseases. Unfortunately, these diseases are the main cause of death in spite of advances in medicine and increasing public awareness of prevention. It is believed that better understanding both molecular potential of this cytokine and the impact in cancerogenesis and others inflammatory diseases may cause using TNF-α as a molecular marker in these diseases and will make it possible to observe the effects of anti-inflammatory therapy. It will be able to cause a drop in the incidence of these diseases and better monitoring of them.

Opis:: Purpose: Growth differentiation factor-15 (GDF- 15) protein belongs to a transforming growth factor-β family which determines the growth and differentiation of cells. In cancers, GDF-15 influences on the proliferation, differentiation, viability, migration and invasiveness of cancer cells. The aim of our study was to evaluate the expression of GDF-15 in the tissue and its levels in sera of patients with colorectal cancer. Materials and methods: The level of GDF-15 in the sera of 55 patients diagnosed with colorectal cancer was determined using the ELISA method whereas expression of this protein was performed by immunohistochemical method. Results: The mean value of GDF-15 levels in the sera of patients with colorectal cancer was significantly higher than in healthy control group (p<0.001). The expression of GDF-15 in the tissue was weak, moderate and strong in 23.6%, 15.7% and 60.7% cases, respectively. Statistical analysis showed that the expression of GDF-15 correlated with patients’ age (p<0.005) and non-mucinous type of cancer (p<0.001). The high GDF-15 levels in the serum was associated with tumor size (p<0.01) and distant metastases (p<0.05). Conclusions: According to our results, we postulate that the level of GDF-15 in serum can be use to assess the metastatic behavior of colorectal cancer

Opis:: Objectives The objective of the present study was to observe the effects of 50 Hz magnetic fields (MFs) on the immune function of splenic lymphocytes in mice. Material and Methods Twenty male Kunming mice (6 weeks old), weighing 18– 25 g, were randomly divided into sham exposure (N = 10) and 500 μT MFs (N = 10) groups. The mice in the MFs group were exposed to 500 μT MFs for 8 h daily (5 days/week) for up to 60 days. In vitro study was carried out to examine the effects of 50 Hz MFs on the expression of inflammatory factor genes and a cluster of differentiation 69 (CD69) in mouse prime splenic lymphocytes activated by para-Methoxyamphetamine (PMA) and ionomycin. In the in vitro experiments, lymphocytes were isolated from the spleen of 10 healthy Kunming mice, the cells were cultured in the Roswell Park Memorial Institute 1640 medium (RPMI-1640) and exposed to 0 μT, 250 μT, 500 μT, or 1 mT MFs in an incubator under 5% carbon dioxide (CO₂) at 37°C for 6 h. The levels of interleukin-2 (IL-2), IL-4, interferon-gamma (IFN-γ), GATA binding protein 3 (GATA-3) and T cell-specific T-box transcription factor (T-bet) were assessed by the real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR), respectively. The expression of CD69 was checked using the flow cytometry. Results Under our experimental conditions, body weight of the mice exposed to occupational, extremely low frequency- electromagnetic fields (ELF-EMFs) significantly decreased on day 20 and day 30. There were no significant changes observed in vivo in spleen weight, splenic coefficient, splenic histology profile and cytokine production in spleen tissues. Our in vitro experiments showed that 50 Hz MFs had no effect on the expression of these genes and CD69 to primary splenic cells. Conclusions In conclusion, under the applied experimental conditions, occupational exposure to 50 Hz magnetic field did not alter responses of inflammatory genes and activation of splenic lymphocytes in mice, except for body weight.

Opis:: Kinins, universal mediators of inflammation, are recognized by two kinds of receptors, B1 and B2, which have been found to be expressed in numerous cell types of several species. However, the knowledge of the regulation of these receptors in leukocytes is still not satisfactory. In the current work, we have demonstrated a constitutive production of B2 receptor mRNA in the human promonocyte U937 cells and its two-fold augmentation after cell differentiation with retinoic acid and phorbol ester. Bradykinin and des-Arg10-kallidin induced the expression of both B2 and B1 receptors in cells before and after differentiation. Generally, the undifferentiated cells were more susceptible to bradykinin-dependent induction of kinin receptors (increases by approximately 250% and 200% for B2 and B1 receptors, respectively). The induction, by approx. 200%, of B1 receptor by des-Arg10-kallidin was detected on both mRNA and protein levels. In addition, an unexpected strong induction of B2 receptor by this compound was observed in the retinoic acid- and phorbol ester-differentiated cells (by 150% and 200%, respectively) that suggests a possible autoregulation of kinin receptors by own agonists during the inflammatory state. On the other hand, a strong enhancement of the expression of both receptors by interleukin 1β, especially in the phorbol ester-differentiated cells, indicates the involvement of kinin receptors in the propagation of the inflammatory processes.
