[Ab] Resumo:Costunolide is known to possess anti-inflammatory and antitumor activity, but its role in tumor angiogenesis, the key step involved in tumor growth and metastasis, and the involved molecular mechanism is still unknown. We aimed to investigate the effects of costunolide on key components of inflammatory angiogenesis in the murine cannulated sponge implant angiogenesis model. Polyester-polyurethane sponges, used as a framework for fibrovascular tissue growth, were implanted in Swiss albino mice and costunolide (5, 10 and 20 mg/kg/day) was administered for 14 days through installed cannula. The implants collected at day 14 post-implantation were processed for the assessment of hemoglobin (Hb), myeloperoxidase (MPO), N-acetylglucosaminidase (NAG) and collagen, which were used as indices for angiogenesis, neutrophil and macrophage accumulation, and extracellular matrix deposition, respectively. Relevant inflammatory, angiogenic and fibrogenic cytokines were also determined. Costunolide treatment attenuated the main components of the fibrovascular tissue, wet weight, vascularization (Hb content), macrophage recruitment (NAG activity), collagen deposition, and the levels of vascular endothelial growth factor (VEGF), interleukin (IL)-1ß, IL-6, IL-17, tumor necrosis factor (TNF)-α and transforming growth factor (TGF-ß). Regulatory function of costunolide on multiple parameters of the main components of inflammatory angiogenesis has been revealed giving insight into the potential therapeutic benefit underlying the anti-angiogenic actions of costunolide.

[Ab] Resumo:There was executed the examination of patients with occupational chronic mercury intoxication in the post-exposure period after the exposure to metallic mercury vapor. 47 persons with an established diagnosis of chronic mercury intoxication (HMI) passed the laboratory and immunological examination in the period of exposure to metallic mercury vapor in a production environment. The average age of men accounted for 49.2±1.2 years. The experience of work in hazardous working conditions amounted of 21.65±1.61 years (1 observation). All these same cases were observed in the institute clinic again after 5 years (2 observation) and 10 years (3 observation). A control group of healthy men consisted of 47 cases included persons of representative both age and general work experience, without a professional route of contact with hazardous substances. The level of such cytokines as IL-1ß, IL-2, IL-4, IL-6, TNF-a, INF-y and neurotropic IgG class antibodies directed to proteins of the nervous tissue (NF-200, GFAP, MBP, B-dependent Ca-channel, Glu-R, DA-R, R-GABA, Ser-R, R-Chol, DNA, B2GP) in serum were determined by enzyme linked immunosorbent assay. There was established the gain in the imbalance of inflammatory mediators and production ofneural antibodies in dynamics after the termination of the production in conditions of metallic mercury vapors. Revealed features of the regulatory relationship between the level of cytokines and the severity of the autoimmune process were shown to contribute to the maintenance and progression of neurodegenerative processes. There was recommended the identification of immunoregulatory markers (IL-1ß, IL-4, TNF-a, NF-AT to 200, GFAP, S-100) as an additional criteria for the diagnosis of health disorders in operating and monitoring the course of the progredient professional mercury intoxication.

[Ab] Resumo:There are considered features of disorders of the immune response in chronic exposure to dust aerosols. The detected changes of indices of the immune status of employees of the dust dangerous occupations and patients with chronic dust pathology of the lungs were unidirectional in the character, which is probably caused by manifestations of nonspecific response of the immune system to the dust factor. The deterioration of cellular immunity, humoral immunity and cytokine profile predisposes to the occurrence of immunopathologic states, contributing to the development of caused by both worksite and occupation pathology.

[Ab] Resumo:Pulmonary Mycobacterium avium complex (MAC) infection is increasing in prevalence worldwide even in immunocompetent individuals. Despite its variable clinical course, the clinical and immunological factors associated with radiographical severity and progression are not largely unknown. We aimed to study the association between the inflammatory cell and cytokine profiles at the local infected site, and the radiological severity and/or progression of pulmonary MAC infection. In this retrospective cohort study, 22 healthy subjects and 37 consecutive patients who were diagnosed as having pulmonary MAC infection by positive cultures of bronchoalveolar lavage (BAL) fluids were enrolled. The 37 patients were divided into 2 groups based on the predominant BAL inflammatory cell type: the lymphocyte-dominant (LD) group and neutrophil-dominant (ND) groups. The high-resolution computed tomography score in both the lavaged segment and whole lung and cytokines profiles were compared between the 2 groups. The clinical course after the BAL procedure was also compared between the 2 groups. Both the segment and whole lung scores in the ND group were significantly higher than the LD group (P < 0.001). Levels of IL-8 in the BAL fluids were significantly higher in the ND group compared to the LD group (P = 0.01). In contrast, levels of IL-22 were significantly lower in the ND group compared to the LD group (P < 0.001). The prevalence of patients who showed deterioration of the disease was significantly higher in the ND group (83.3%) than the LD group (12.5%) (P < 0.01). Neutrophil-predominant inflammatory response at the infected site is associated with the radiographical severity and progression of pulmonary MAC infection.

[Ti] Título:Elevations of novel cytokines in bacterial meningitis in infants.

[Ab] Resumo:BACKGROUND: Bacterial meningitis is challenging to diagnose in infants, especially in the common setting of antibiotic pre-treatment, which diminishes yield of cerebrospinal fluid (CSF) cultures. Prior studies of diagnostic markers have not demonstrated sufficient accuracy. Interleukin-23 (IL-23), interleukin-18 (IL-18) and soluble receptor for advanced glycation end products (sRAGE) possess biologic plausibility, and may be useful as diagnostic markers in bacterial meningitis. METHODS: In a prospective cohort study, we measured IL-23, IL-18 and sRAGE levels in CSF. We compared differences between infected and non-infected infants, and conducted receiver operating characteristic (ROC) analyses to identify individual markers and combinations of markers with the best diagnostic accuracy. RESULTS: 189 infants <6 months, including 8 with bacterial meningitis, 30 without meningitis, and 151 with indeterminate diagnosis (due to antibiotic pretreatment) were included. CSF IL-23, IL-18 and sRAGE levels were significantly elevated in infants with culture proven meningitis. Among individual markers, IL-23 possessed the greatest accuracy for diagnosis of bacterial meningitis (area under the curve (AUC) 0.9698). The combination of all three markers had an AUC of 1. CONCLUSIONS: IL-23, alone and in combination with IL-18 and sRAGE, identified bacterial meningitis with excellent accuracy. Following validation, these markers could aid clinicians in diagnosis of bacterial meningitis and decision-making regarding prolongation of antibiotic therapy.

[Ti] Título:Therapeutic Effects of Resiniferatoxin Related with Immunological Responses for Intestinal Inflammation in Trichinellosis.

[Ab] Resumo:The immune response against Trichinella spiralis at the intestinal level depends on the CD4+ T cells, which can both suppress or promote the inflammatory response through the synthesis of diverse cytokines. During the intestinal phase, the immune response is mixed (Th1/Th2) with the initial predominance of the Th1 response and the subsequent domination of Th2 response, which favor the development of intestinal pathology. In this context, the glucocorticoids (GC) are the pharmacotherapy for the intestinal inflammatory response in trichinellosis. However, its therapeutic use is limited, since studies have shown that treatment with GC suppresses the host immune system, favoring T. spiralis infection. In the search for novel pharmacological strategies that inhibit the Th1 immune response (proinflammatory) and assist the host against T. spiralis infection, recent studies showed that resiniferatoxin (RTX) had anti-inflammatory activity, which decreased the serum levels of IL-12, INF-γ, IL-1ß, TNF-α, NO, and PGE2, as well the number of eosinophils in the blood, associated with decreased intestinal pathology and muscle parasite burden. These researches demonstrate that RTX is capable to inhibit the production of Th1 cytokines, contributing to the defense against T. spiralis infection, which places it as a new potential drug modulator of the immune response.

[Ab] Resumo:Degenerative lumbar disease (DLD) is a significant issue for public health. Posterior lumbar intervertebral fusion with cages (PLIFC) has high-level fusion rate and realignment on DLD. However, there are some complications following the surgery. Alginate oligosaccharides (AOS) have antioxidant and anti-inflammatory activities and may be suitable for infection therapy. MiR-155 is a biomarker associated with inflammatory and oxidative stress. AOS may promote PLIFC therapy by regulating miR-155. Pluronic nanoparticles and oligosaccharide nanomedicine of alginate sodium (ONAS) were prepared with ampicillin at size <200 nm. Ninety-six DLD osteoporosis patients received PLIFC and were evenly assigned into ONAS group (OG, oral administration of 100 mg ONAS daily) and control group (PG, 100 mg pluronic nanoparticles). Serum miR-155 level was measured by real-time quantitative PCR. The levels of superoxide dismutase (SOD), glutathione (GSH), aspartate aminotransaminase (AST), alanine aminotransferase (ALT), interleukin-1ß (IL-1ß), and interleukin-1 receptor antagonist (IL-1ra) were measured. Weighted mean difference (WMD), relative risk (RR), complications, surgery infection rate, fusion rate, and Japanese Orthopaedic Association (JOA) scores were used to evaluate therapeutic efficacy. After 1-month therapy, infection rates and side effects were lower in OG than those in PG (RR =0.64, 95% confidence interval [CI] [0.48, 0.84], =0.001). The fusion rates were higher in OG than in PG (WMD =21.96, 95% CI [-0.24, 37.62], =0.021). The JOA scores were higher in OG than in PG (RR =0.52, 95% CI [0.33, 0.84], =0.007), and no significant difference was found for the visual analog scale and Oswestry Disability Index. Serum levels of miR-155, ALT, AST, and IL-1ß were lower while SOD, GSH, and IL-1ra were higher in OG than in PG. MiR-155 mimic increased the levels of ALT, AST, and IL-1ß and reduced the levels of SOD, GSH, and IL-1ra. In contrast, miR-155 inhibitor had reverse results. Therefore, ONAS has better improvement in complications and therapeutic effects on DLD by regulating serum miR-155.

[Ab] Resumo:Immunotherapy by sublingual administration of allergens provides high patient compliance and has emerged as an alternative to subcutaneous immunotherapy for the treatment of IgE-associated allergic diseases. However, sublingual immunotherapy (SLIT) can cause adverse events. Development of allergen delivery systems enabling more efficient delivery and hence lower allergen load might reduce the adverse events. In the present study, we have investigated neutral and cationic liposomes as delivery systems of ovalbumin (OVA), as a model allergen, in an OVA-induced allergic airway inflammation model. We investigated the liposome carriers' ability to improve tolerance induction of antigens compared to the corresponding dose of free OVA. Mice were treated sublingually over 2 weeks with free or liposome encapsulated OVA followed by intraperitoneal injections and intranasal challenge. Mice sublingually treated with OVA-liposomes showed a significant reduction of airway eosinophilia and splenocyte proliferation in comparison to free OVA. A similar nonsignificant pattern was seen for OVA-specific IgE antibodies. In addition, reduced levels of interferon-γ and interleukin-5 were observed in spleen cell culture supernatants from OVA-liposome-treated mice compared to the sham-treated group. In conclusion, in vivo efficacy data showed that prophylactic SLIT with OVA-liposomes is significantly more effective in preventing allergic inflammation than the corresponding dose of free OVA.

[Ab] Resumo:PURPOSE: Influenza viruses are a common cause of human respiratory infections, resulting in epidemics of high morbidity and mortality. We investigated the effect of a novel mitogen-activated protein kinase (MAPK) inhibitor in vitro and in a murine influenza model to further explore whether p38 MAPK inhibition could reduce viral replication. METHODS: In vitro, the antiviral effect of p38 MAPK inhibitor BCT194 was evaluated in differentiated human bronchial epithelial cells (HBECs); in vivo, female BALB/c mice were infected intranasally with 150 pfu of influenza H1N1 A/Puerto Rico/8/34 and treated with BCT197 (a closely related p38 MAPK inhibitor with an IC50 value of<1 µM, currently in clinical testing), dexamethasone or oseltamivir (Tamiflu) starting 24 h post infection. Body weight, bronchoalveolar lavage cells, cytokines, total protein and lactate dehydrogenase as well as serum cytokines were measured; a subset of animals was evaluated histopathologically.Results/Key findings. p38MAP kinase inhibition with BCT194 had no impact on influenza replication in HBECs. When examining BCT197 in vivo, and comparing to vehicle-treated animals, reduced weight loss, improvement in survival and lack of impaired viral control was observed at BCT197 concentrations relevant to those being used in clinical trials of acute exacerbations of chronic obstructive pulmonary disease; at higher concentrations of BCT197 these effects were reduced. CONCLUSIONS: Compared to vehicle treatment, BCT197 (administered at a clinically relevant concentration) improved outcomes in a mouse model of influenza. This is encouraging given that the use of innate inflammatory pathway inhibitors may raise concerns of negative effects on infection regulation.

[Ab] Resumo:OBJECTIVE: Angelica dahurica is a well-known traditional Chinese Medicine (TCM), while little information is available about its effects on pressure sores. We aimed to investigate the clinical effect of Angelica dahurica on patients with I-II phase pressure sores, as well as the underlying mechanism. METHODS: Patients (n = 98) with phase I and phase II pressure sores were enrolled and randomly assigned to control and treated groups. In addition to holistic nursing, patients in the control group received compound clotrimazole cream, while patients in the treated group received continuous 4 weeks of external application of Angelica dahurica dressing. Therapeutic effect was recorded, along with the levels of interleukin-8 (IL-8), epidermal growth factor (EGF), transforming growth factor (TGF)-ß, and vascular endothelial growth factor (VEGF). Besides, HaCaT cells were cultured with different concentrations of Angelica dahurica, and then cell viability, clone formation numbers, cell cycle, and levels of cyclin D1 and cyclin-dependent kinase (CDK) 2 were determined. RESULTS: The total effective rate in the treated group was significantly higher than in the control group. Levels of IL-8, EGF, TGF-ß, and VEGF were statistically increased by Angelica dahurica. In addition, the cell viability and clone formation numbers were significantly upregulated by Angelica dahurica in a dose-dependent manner. Also, the percentage of cells in G0/G1 phase, and levels of cyclin D1 and CDK2 were significantly elevated. CONCLUSION: Our results suggest that Angelica dahurica may provide an effective clinical treatment for I-II phase pressure sores.
