Effect of gut microbiota intervention on inflammatory responses and cellular immune function in hepatocellular carcinoma patients undergoing radiotherapy

ObjectiveTo analyze the changes in nutritional status, inflammatory response and cellular immune status of Hepatocellular Carcinoma (HCC) patients who received radiotherapy under GMB intervention and to clarify the effect of GMB intervention on HCC. MethodsNinety-two patients with HCC receiving radiotherapy were randomized into study and observation groups, 46 in each group. The control group used conventional radiotherapy, and the study group used the gut microbiota intervention. The gut microbiota before and after radiotherapy, and the liver function, clinical efficacy, inflammatory response, cellular immunity, and nutritional status before and after treatment were compared. ResultsCompared with the control group, the number of lactobacillus and Bifidobacterium increased significantly, the clinical efficacy was significantly enhanced, the liver function, cellular immunity and nutritional status were significantly improved, and the inflammatory response was significantly reduced, with statistically significant differences (P < 0.05). Conclusiongut microbiota intervention can improve the effect of radiotherapy and improve liver function in patients, and the mechanism is related to regulating cellular immune function of patients and inhibiting inflammatory response in patients.

Impacts of ocean acidification and hypoxia on cellular immunity, oxygen consumption and antioxidant status in Mediterranean mussel

There is growing recognition that the hypoxic regions of the ocean are also becoming more acidic due to increasing levels of global carbon dioxide emissions. The impact of water acidification on marine life is largely unknown, as most previous studies have not taken into account the effects of hypoxia, which may affect how organisms respond to low pH levels. In this study, we experimentally examined the consequences of water acidification in combination with normoxic or hypoxic conditions on cellular immune parameters in Mediterranean mussels. We measured total hemocyte counts in hemolymph, the cellular composition of hemolymph, phagocytosis, reactive oxygen species (ROS) production. General response of the organism was evaluated on the basis of the activity of antioxidant enzymes in the hepatopancreas, as well as respiratory rates over an 8-day exposure period. The mussels were exposed to low pH conditions (7.3), either under normoxic conditions (dissolved oxygen concentration of 8 mg/L) or hypoxic conditions (dissolved oxygen concentration of 2 mg/L). The parameters were assessed at days 1, 3, 6, and 8 of the experiment. Experimental acidification under normoxic conditions reduced THC and ROS production by hemocytes during later stages of exposure, but phagocytic activity (PA) only decreased at day 3 and then recovered. Combined acidification and hypoxia suppressed PA in hemocytes at the beginning of exposure, while hemocyte ROS production and THC decreased by the end of the experiment. The hemolymph cellular composition and activity of antioxidant enzymes were unaffected by acidified conditions under different oxygen regimes, but mussel respiratory rate (RR) decreased with a more significant reduction in oxygen consumption under hypoxia. Mussels showed a relatively high tolerance to acidification in combination with various dissolved oxygen levels, although prolonged acidification exposure led to increased detrimental effects on immunity and metabolism.

The impact of plant cryoextract on productivity and factors of innate immunity of pond fish against the background of stress in the experiment

The search for effective and environmentally friendly means to increase the productivity and natural resistance of animals, especially in aquaculture, remains an urgent socio-economic task. This article presents the results of the study of the effect of the cryobiological supplement ‘Immunolife-Fish’, based on medicinal plants, on the weight gain of juvenile common carp (Cyprinus carpio) and indicators of innate immunity of two-year-old common carp (Cyprinus carpio) and silver carp (Hypophthalmichthys molitrix) under the influence of thermal stress factor in aquarium conditions. It was found that the weight gain of juvenile carp treated with the cryobiological supplement ‘Immunolife-Fish’ was higher than that of the control group at all stages of the study. The increase was most pronounced during the first 42 days of feeding. A significant increase in the number of leukocytes was found in the blood of fish (common carp and silver carp) exposed to a heat stressor compared to control values. In fish that received a supplement of the herbal preparation during stress, this indicator only tended to increase. The effect of the stressor in fish of both species is manifested by a significant increase in the leukocyte content, a decrease in the indicators characterizing the functional state of cellular immunity — phagocytic activity and number of phagocytes, as well as a tendency to decrease the phagocytic index of neutrophils in the blood. The use of the cryobiological supplement ‘Immunolife-Fish’ in fish exposed to stress not only prevented the decrease in the phagocytic activity of neutrophils but also contributed to a slight increase in their activity in comparison with the control. A significant decrease in the activity of lysozyme and the level of circulating immune complexes, as well as an increase in the content of seromucoids, was found in the blood serum of common and silver carp under the influence of the stress factor. The use of the drug against the background of stress leveled the negative changes in the above indicators characterizing the state of the humoral link of innate immunity. In addition, a mild immune stimulating effect of the cryobiological supplement on fish of both species, which were kept in optimal conditions, was noted. The research is aimed at the development and testing of organic, environmentally friendly anti-stress and immunostimulant agents in commercial fish farming

Algorithm for assessing the level of T cell immune response against SARS-CoV-2 and the results of its application in unvaccinated and vaccinated people who have been infected with COVID-19

Antigen (AG)-specific T cell activity was compared in two groups of patients: those who underwent COVID-19 in 2021 during the circulation of the SARS-CoV-2 delta virus strain (43 individuals); and those who underwent COVID-19 in 2022 (Omicron strain, 23 individuals). The diagnosis was confirmed by PCR analysis of nasopharyngeal and oropharyngeal swabs. The 23 individuals following COVID-19 caused by SARS-CoV-2 (omicron) were part of a cohort of 41 volunteers who were examined multiple times during 2021–2023: during vaccination, after vaccination, before revaccination, and subsequently after illness (6–8 times in total). Due to this, it was possible to compare the indices of specific humoral and cellular immunity in the same patients 1–2 months before and after breakthrough infection. Detection of AG-specific T cells and assessment of their activity by AG-stimulated IFNγ production was carried out by our own previously developed method (Patent RU № 2780369 C1). For stimulation of memory T effectors in vitro, the same antigens were used to determine the concentration of antibodies against SARS-CoV-2 by ELISA method. A total of about 300 blood samples from healthy subjects and patients after COVID-19 were analyzed. Each sample was tested against 3 SARS-CoV-2 antigens and in 2 stimulation modes. A qualitative assessment algorithm for AG-specific T cell activity has been proposed that can be used to monitor the state of cellular immunity in a population in which SARS-CoV-2 virus continues to circulate and to create insights into what level of T cell activation is sufficient to prevent or reduce the severity of SARS-CoV-2 infection. Unvaccinated COVID-19 (SARS-CoV-2, Delta) survivors lacked AG-specific T cells to RBD SARS-CoV-2, but T cell specificity to full-length S glycoprotein at the same level, qualitatively assessed as low in 52% of the group, persisted for up to six months. In previously unvaccinated COVID-19 vaccinees, this duration of persistence of AG-specific T cells in circulating blood was achieved only after revaccination. Hybrid immunity, which we traced as a result of vaccination after COVID-19 (Delta strain) or as a breakthrough infection (SARS-CoV-2, Omicron), is characterized by the highest indices of memory T cell activity (43–46% of the group — normal activity of AG-specific cells, 30–43% — high activity) to all used antigens and the longest duration of preservation of indices at this level. Further investigation of the level of antiviral immunity after COVID-19 may be important for predicting the outcome of new waves of SARS-CoV-2 infection.

Exploring immune status in peripheral blood and tumor tissue in association with survival in patients with multi-organ metastatic colorectal cancer

ABSTRACT Colorectal cancer (CRC) raises considerable clinical challenges, including a high mortality rate once the tumor spreads to distant sites. At this advanced stage, more accurate prediction of prognosis and treatment outcome is urgently needed. The role of cancer immunity in metastatic CRC (mCRC) is poorly understood. Here, we explore cellular immune cell status in patients with multi-organ mCRC. We analyzed T cell infiltration in primary tumor sections, surveyed the lymphocytic landscape of liver metastases, and assessed circulating mononuclear immune cells. Besides asking whether immune cells are associated with survival at this stage of the disease, we investigated correlations between the different tissue types; as this could indicate a dominant immune phenotype. Taken together, our analyses corroborate previous observations that higher levels of CD8+ T lymphocytes link to better survival outcomes. Our findings therefore extend evidence from earlier stages of CRC to indicate an important role for cancer immunity in disease control even after metastatic spreading to multiple organs. This finding may help to improve predicting outcome of patients with mCRC and suggests a future role for immunotherapeutic strategies.

Association of dexmedetomidine and intraoperative thermal insulation with postoperative outcomes in colorectal cancer resection

Objective To investigate the effects of dexmedetomidine combined with intraoperative thermal insulation on postoperative cognitive function, cellular immune status and inflammatory markers in patients undergoing radical resection for colorectal cancer. Methods Fifty patients who underwent radical resection of colorectal cancer in our hospital from March 2020 to September 2021 were selected and divided into observation group (26 cases with dexmedetomidine combined with intraoperative thermal insulation intervention) and control group (24 cases with conventional anesthesia management). The evaluation measures included the mini-mental state scale (MMSE) score, CD4+ T cell, CD8+ T cell ratio and CD4+/CD8+ ratio, the level of inflammatory markers (IL-6, TNF-α, CRP), and the incidence of postoperative complications. Results The MMSE score of the observation group was significantly higher than that of the control group on the 3rd day after operation (p < 0.001). After treatment, the proportion of CD4+ T cells, the proportion of CD8+ T cells and the ratio of CD4+/CD8+ in observation group were higher than those in control group (p < 0.01), while the inflammatory markers IL-6, TNF-α and CRP were lower than those in control group (p < 0.01). The incidence of postoperative cognitive dysfunction (POCD) in the observation group (7.69%) was significantly lower than that in the control group (33.33%) (p = 0.010), and the postoperative infection rate was also significantly decreased (p = 0.042). Conclusion Dexmedetomidine combined with intraoperative insulation can significantly improve postoperative cognitive function, maintain immune balance, reduce inflammatory response, and reduce the incidence of POCD and other postoperative complications in patients with radical resection of colorectal cancer.

Disulfidptosis-Related LncRNA Signatures for Prognostic Prediction in Kidney Renal Clear Cell Carcinoma

Introduction BackgroundDisulfidptosis is a prevalent apoptotic mechanism, intrinsically linked to cancer prognosis. However, the specific involvement of disulfidptosis-related long non-coding RNA (DRLncRNAs) in Kidney renal clear cell carcinoma (KIRC) remains incompletely understood. This study aims to elucidate the potential prognostic significance of disulfidptosis-related LncRNAs in KIRC. Materials and MethodsExpression profiles and clinical data of KIRC patients were retrieved from the TCGA database to discern differentially expressed DRLncRNAs correlated with overall survival. Cox univariate analysis, Lasso Regression, and Cox multivariate analysis were used to construct a clinical prediction model. ResultsSix signatures, namely FAM83C.AS1, AC136475.2, AC121338.2, AC026401.3, AC254562.3, and AC000050.2, were established to evaluate overall survival (OS) in the context of Kidney renal clear cell carcinoma (KIRC) in this study. Survival analysis and ROC curves demonstrated the strong predictive performance of the associated signature. The nomogram exhibited accurate prognostic predictions for overall patient survival, offering substantial clinical utility. Gene set enrichment analysis revealed that risk signals were enriched in various immune-related pathways. Furthermore, the risk features exhibited significant correlations with immune cells, immune function, immune cell infiltration, and immune checkpoints. ConclusionThis study has unveiled, for the first time, six disulfdptosis-related LncRNA signatures, laying a solid foundation for enhanced and precise prognostic predictions in KIRC.

“Enzimsporin” probiotic effect on the growth, vitality and physiological state of sterlet in the RAS

Despite the great interest in the use of probiotics to strengthen the immune characteristics of animals, there is not enough work on this issue, so we set ourselves the goal of studying the physiological state and immune status of sterlet grown in the ultrasound, which was fed with the addition of the probiotic “Enzimsporin”. A control group and three experimental groups were selected for the experiment, individuals were selected according to the principle of analogues of 50 in each group. For 60 days, the sterlet of the experimental groups was fed with the addition of probiotic in dosages of 1, 1.5 and 2 g/kg. Based on the combination of high linear-weight indicators and survival, we evaluated the hematological characteristics of individuals in the group that received a probiotic dosage of 1 g/kg of feed. In this experimental group, the number of erythrocytes and leukocytes in the blood did not significantly differ. When using a probiotic in a fish leukogram, the proportion of immature myeloid cells, including rod-shaped neutrophils, decreases from 3.1% to 0.6%. At the same time, there were no significant differences in the proportion of mature segmented neutrophils. The use of probiotics significantly increases the amount of lysosomal cationic protein in neutrophils to a value of 1.94 units of blood compared to the control group, whose values were 1.05 units, which indicates a favorable state of cellular immunity and a high immune status of fish in this group as a whole.

Immune and genetic profile of workers with metabolic syndrome contaminated with benzene (based on the example of the petrochemical industry)

Exposure to harmful chemical factors of production can contribute to the development of metabolic disorders in workers in the petrochemical industry. Oil production conditions are associated with exposure to endocrine disruptors, such as aromatic hydrocarbons, whose effects are associated, among other things, with disorders of immuno-endocrine regulation.&#x0D; The aim of the study was to analyze the features of the immune and genetic status of workers in the oil-producing segment of the petrochemical industry with metabolic syndrome contaminated with benzene.&#x0D; 142 operators of the oil production enterprise with pathology with metabolic syndrome were examined. The observation group included workers (n=94) characterized by contamination of the biological medium with benzene. The comparison group consisted of 48 people who were not contaminated with benzene. The state of cellular immunity was assessed by flow cytometry (CD3+CD8+, CD3+CD95+, CD3+), cytokine profile by enzyme immunoassay (IL‑6). Gene polymorphism was studied by real-time PCR.&#x0D; In workers with metabolic syndrome contaminated with benzene, the features of the clinical course of the metabolic syndrome, accompanied by functional and laboratory signs of atherosclerotic vascular changes, as well as an imbalance of the immune profile, whose phenotypes were: an increase in the absolute and relative content of CD3+CD8+ lymphocytes (1.3–1.6 times, respectively) (p&lt;0.05), CD3+ lymphocytes (1.2–1.3 times) (p&lt;0.05) relative to the comparison group, CD95+ cluster deficiency in relation to the reference interval and the indicators of the comparison group (1.4–1.9 times; p&lt;0.05), IL-6 hyperproduction (1.6 times; p&lt;0.05) relative to the values of the corresponding indicators of the group of workers where benzene contamination was absent. The genetic profile of workers (SNP) contaminated with benzene allowed us to establish a 1.4-fold increased prevalence of the C-allele of the FADS2 gene (OR=2.13; 95% CI: 1.05–4.29, p&lt;0.05); 2.3 times the G-allele (OR=3.30; 95% CI: 1.46–7.33, p&lt;0.05) of the TP53 gene.&#x0D; Established in operators of the oil-producing segment of the petrochemical industry with metabolic syndrome contaminated with benzene, features of the immune status: an increase in the expression of CD3+ and CD8+ lymphocyte clusters, IL-6 cytokine, and a decrease in CD95+ lymphocyte reception (p&lt;0.05) were accompanied by polymorphisms of candidate genes FADS2 (rs174583) and TP53 (rs 1042522) associated with obesity and apoptosis.&#x0D; Ethics. The study was approved by the ethics committee of the Federal Scientific Center for Medical and Preventive Health Risk Management Technologies. All patients were informed about the purpose of the study, and voluntary informed consent was obtained.

Роль клеточного иммунитета в развитии злокачественных новообразований у лиц, подвергшихся хроническому облучению

Some long-term effects of radiation could be related to changes in the immune system resulting from radiation exposure. Immunity disorders caused by radiation can influence carcinogenesis. Cellular immunity factors were investigated in peripheral blood of workers chronically exposed to occupational combined radiation (external gamma-rays and internal alpha-particles), with malignant neoplasms diagnosed after blood samples were taken or without them, and in the control group. The aim of this study was examine effects of radiation on the cellular immunity status in individuals chronically exposed to ionizing radiation who had malignant neoplasms developed after blood sampling. The relative and absolute number of lymphocyte subpopulations (total T-cells, T-helpers, T-cytotoxic, total B-cells, NK-cells, NKT-cells and activated T-cells) was detected by flow cytofluorometry. The absolute number of T-cells was significantly reduced in workers chronically exposed to occupational combined irradiation, with or without malignancies, compared to the control, which may contribute to tumor progression at an early stage of its onset. At the same time, workers without malignancies had a significant increase in the relative number of T-cytotoxic lymphocytes, which may be a factor preventing tumor development. A significant increase in the relative number of natural killer cells (NK cells) was detected in individuals with malignant neoplasms chronically exposed to occupational combined irradiation, compared with the control, which may indicate enhanced antitumor defense that developed in response to exposure to tumor antigens. In addition, a significant decrease in the absolute and relative number of T- and B-lymphocytes was found in the group of workers with malignant neoplasm, compared with the control. A significant increase in the relative number of T-helpers was found in both groups of workers. Since the role of T-helpers in the antitumor response is ambiguous, additional research on types of T-helpers is planned to clarify the results of the present study

COVID-19 Reinfection: Can Humoral or Cellular Immune Status Predict need for Vaccination and which Vaccine is more Effective: mRNA Booster or Inactivated whole Virus (VLA2001)?

Background/Introduction: The SARS-CoV-2 B.1.1.529 variant (Omicron) has shown high infectivity worldwide, even in vaccinated patients. Little is known about how well naturally acquired immunity protect against further COVID-19 infections in unvaccinated or vaccinated patients. We investigated whether vaccination is still warranted, and if so, what type of vaccine should be used.

Characterization of intestinal fungal community diversity in people living with HIV/AIDS (PLWHA)

Acquired Immune Deficiency Syndrome (AIDS) is a highly dangerous infectious disease caused by the Human Immunodeficiency Virus (HIV), a virus that attacks the human immune system. To explore the correlation between intestinal fungal community and immune function (Immune cells and inflammatory factors) in people living with HIV/AIDS (PLWHA). The feces and blood samples were collected from two groups of subjects: PLWHA and healthy controls. High-throughput sequencing of the internal transcribed spacer 1, flow cytometry, and ELISA were performed to analyze the differences and correlations between fungal microbiota, cellular immune status and serum inflammatory factors in the two groups. There were significant differences in the composition of fungal microbiota between the two groups. The relative abundance of Candida, Bjerkandera, and Xeromyces in PLWHA was significantly higher than that of healthy volunteers (P < 0.01), while the relative abundance of Mycospaerella, Xeroxysium, Penicillium, and Glomerella in PLWHA was significantly lower than that of healthy volunteers. The correlation analysis results show that Mycospaerella and Xeromyces are significantly positively correlated with CD4+/CD8+ T cells and the anti-inflammatory cytokine IL-4. On the other hand, Candida was positively correlated with pro-inflammatory factors negatively correlated with CD4+/CD8+ T cells and the anti-inflammatory cytokine IL-4, while it is positively correlated with pro-inflammatory cytokines. The significant increase in the relative abundance of Candida may be one of the important causes of intestinal damage in PLWHA. The results of this study contribute to the understanding of the relationship between fungal microbiota structure and immune function in the gut ecology of PLWHA.

The influence of physical occupational factors on the immune system

Environmental factors can influence various parts of the immune system, potentiating the formation of immunopathological processes underlying the development of a large group of diseases.&#x0D; The study aims to analyze the results of experimental and observational studies to assess the effect of noise, vibration, and electromagnetic fields (EMF) on immunological parameters.&#x0D; Among the mechanisms of the influence of physical factors on the immune system, most authors single out the action through the neuroendocrine system and the potentiation of oxidative stress.&#x0D; Experimental studies on laboratory animals to assess the effects of noise on the immune system demonstrate the effect of noise on cellular and humoral immunity, the intensity of an allergic reaction, and sensitivity to infectious agents.&#x0D; The results of surveys of workers exposed to industrial vibration indicate the influence of this production factor on humoral, cellular immunity, and cytokine status, however, the detected changes in these immunological parameters may be multidirectional.&#x0D; In vitro experimental studies indicate that after exposure to EMF on immune cells, numerous changes are detected in them. There are studies demonstrating changes in the immune system in people exposed to EMF.&#x0D; Thus, the analysis of literary sources indicates the influence of physical production factors (noise, vibration, EMF) on the immune status of the body, which determines the prospects of research aimed at developing criteria for evaluating changes in immunological parameters to identify groups at increased risk of developing pathology.

Evaluation of the effectiveness of detoxification in the immunorehabilitation of cancer patients

Purpose. Evaluation of the effectiveness of detoxification using enterosorbents in the immunorehabilitation of cancer patients.&#x0D; Materials and methods. 87 patients with metastatic forms of solid tumors of various localizations with metastatic lesions were examined. The patients were divided into 2 groups: study group (41 patients who received detoxification therapy in addition to standard therapy) and comparison group (46 patients who received only standard therapy). The effectiveness of therapy with these drugs was evaluated after one month by assessing clinical and immunological parameters. The assessment of the state of cellular immunity was carried out by flow cytometry.&#x0D; Results. Disturbances in the function of the immune system in the form of insufficiency of the cellular effector link of immunity were detected in all examined patients before the start of therapy. The state of the cellular link of immunity was characterized by an increase in the number of transitional and non-classical subsets of monocytes, an increase in the content of T-, B- and NKT-cells, but with a decrease in NK-cells. An increase in the ratio between the number of T-helpers (CD3+CD4+) and the number of cytotoxic T-cells (CD3+CD8+) was observed in the examined patients. Restoration of cell subsets to the level of control values was found in the examined patients after detoxification therapy as part of immunorehabilitation measures. Significant changes in the number of cells in the blood were absent in the comparison group after the therapy which indicated the absence of a complete relief of the systemic inflammatory response.&#x0D; Conclusion. Chronic toxicosis with the development of a systemic inflammatory reaction on the background of the immune system dysfunctions were found in cancer patients. The use of enterosorbents in complex immunorehabilitation therapy is substantiated and confirmed by the relief of asthenovegetative and dyspeptic syndromes, normalization of the immune system which makes it possible to recommend detoxification therapy during immunorehabilitation measures.

Mycobacteria’s Antibodies Search: Serology, an Important Neglected Means to Establish a Diagnosis and a Prognosis

The WHO has banned the use of blood tests for the diagnostic and prognostic of tuberculosis. This is a monumental error that it never corrected. The current ban deprives the mycobacterial community of a tool that is essential to combat the disease. Serology estimates the humoral immune status of a patient or a population. It is not a substitute to antigen detection, but it is comparable to the tuberculin test which estimates the cellular immune status. Both give an evocative expression of the tubercle bacillus immunosuppressive activity and indicate the mobilization level of the infected patients’ immune defense. In opposition to the tuberculin reaction which makes the cutaneous test devoid of interest after a positive turn, the serology fluctuates according to the antigenic load.

Breeding a new three-breed Cross carp Cyprinus carpio

A new three-breed cross-hybrid of carp has been obtained in the fish farm «Kirya» of the Chuvash region (RF). A comparative assessment of the fingerlings showed the advantages of the cross over other crosses grown in the same farm (Sursky malokostny and Petrovsky) on a number of indicators: weight, body length, indices of high-spin, physical development. In the youngsters of the new cross, the intensity of hematopoiesis (erythropoiesis and leukopoiesis) is higher than in the rest of the studied crosses. The content of lysosomal cationic protein in the blood neutrophils of the new cross-hybrid is at an optimal level and indicates a good state of cellular immunity of fish.

Conjoint analysis of transcriptome and metabolome profiles of normal captivity and arch soil free-range in Meishan pigs.

The hygiene hypothesis has been advanced as a potential explanation for the increasingly high levels of atopy and allergic disease in the general human population. In an effort to conduct a more detailed study of the link between immune activity and the hygiene hypothesis, Meishan pigs raised under normal captivity (NC) or arch soil free-range (ASF) conditions were selected as an experimental model system. Cytokine levels were found to differ significantly between these two groups consistent with a difference in cellular immune status. Integrated transcriptomic and metabolomic profiling of duodenal tissue samples from Meishan pigs were then performed, leading to the identification of differentially expressed genes (DEGs), differentially abundant metabolites (DAMs), and key pathways that were able to distinguish the NC and ASF groups. This approach led to the identification of 1,113 DEGs, as well as 577 and 372 DAMs in positive and negative ion modes, respectively. When an interaction network incorporating DEGs and metabolites associated with immune responsivity was constructed, it included factors such as 9-cis-Retinoic acid, (9Z,11E)-(13S)-13-Hydroxyoctadeca-9,11-dienoic acid and (10E,12Z)-(9S)-9-Hydroxyoctadeca-10,12-dienoic acid. Functional enrichment analyses confirmed that identified DEGs and DAMs were associated with immune-related pathways including the intestinal IgA production and PPAR signaling pathways. Together, these results offer new insight into the roles that particular genes and metabolites enriched in response to environmental stressors in free-range Meishan pigs may play in the regulation of cellular immunity, thus offering a foundation for future efforts to better understand the immunological mechanisms underlying the hygiene hypothesis.

Erisipelas

Erysipelas is an infection of the nonnecrotic superficial skin accompanied by lymphangitis. This infection will cause a clinical picture in the form of well-defined erythematous plaques. Most cases of erysipelas are caused by bacteria, most often the normal skin flora such as Streptococcus bacteria but erysipelas can also be caused by S. aureus and group C or G Streptococcus. Erysipelas can occur at any age. Erysipelas is closely related to the patient’s physical condition and cellular immune status which underlies or facilitates the occurrence of infections, including chronic systemic diseases suffered by these patients, such as diabetes mellitus, immunocompromised states. The lower extremities are the most common predilection for erysipelas. Most erysipelas patients come for treatment with the main complaint of swelling, redness, and pain experienced by the patient accompanied by other complaints such as burning and itching which are predisposing factors to the occurrence of this infection. The diagnosis of erysipelas is based on anamnesis, physical examination and laboratory tests. The management of erysipelas is the administration of antibiotics and wound care.

Study of the immune state in different variants of anesthetic support for total laryngectomy

Peculiarities of operative interventions for malignant neoplasms of the larynx, their traumatic nature, and side effects of opioid use require the search for optimization of anesthesia and perioperative analgesia aimed at reducing surgically and anesthetically induced immunosuppression and related negative consequences.Aim: to investigate the immune status of laryngeal cancer patients with different options of anesthetic support for total laryngectomy and to evaluate the relationship between perioperative im­munosuppression and the use of various adjuvant components of analgesia (dexmedetomidine and lidocaine).100 patients with T3-4N0-3M0 laryngeal cancer who underwent total laryngectomy were included in the study. Patients were evenly and comparably divided into 4 research groups (n=25) based on the main clinical and age-sex characteristics (p&gt;0.05) depending on the use of adjuvant components of multimodal anesthesia: in the group 1 they were not used, only opioid analgesics, in group II – lidocaine was used, in group III – dexmedetomidine, and in group IV – both lidocaine and dexmedetomidine. Studies of markers of the immune state (leucoformula, IL-2 and TNF-α) were carried out on the 1st, 2nd, 5th and 7th days after surgery. Statistical analysis was carried out using STATISTICA v.6.1 (Statsoft Inc., USA, license number AGAR909E415822FA), it included parametric and non-parametric, and analytical statistics, parametric and non-parametric variance analysis descriptive of ANOVA, repeated measurements with an assessment of the degree of influence of an independent factor on the studied characteristic. A relatively stable state of cellular immunity and a certain suppression of humoral immunity after total laryngectomy was determined. Immunosuppression was most evident on the 2nd day after surgery in the group 1 with standard opioid anesthesia. The best indicators of the immune state were determined in group IV of the study. The method of anesthesia had the greatest influence on the state of immunosuppression (according to TNF-ɑ) on the 2nd day after surgery – K=30.9% (p&lt;0.001) and was observed within a week after surgery. Lidocaine and dexmedetomidine, as adjuvant components of multimodal anesthesia for total laryngectomy, when used together led to less immunosuppression, contributed to better rates of recovery of the immune status of laryngeal cancer patients compared to the standard approach with the use of opioids.
