Relevance. The development of multiple organ lesions in undifferentiated connective tissue disease leads to secondary immunodeficiency, which triggers oral homeostasis disruption and activates periodontal pathogens, which produce anti-inflammatory cytokines, which trigger the mechanisms of periodontal destruction. Purpose – to establish the relationship between undifferentiated connective tissue disease in children and their predisposition to periodontal inflammation and destruction.Materials and methods. The study examined the patients, aged 15 to 17 years old, of the endocrinological department of the Children's Clinical Hospital of N. N. Burdenko Voronezh State Medical University. All examined children had the same diagnosis of undifferentiated connective tissue disease. The control group consisted of 15 children with healthy periodontium. Silness-Loe plaque index (Loe H., Silness J., 1962) at the gingival margin assessed the children periodontal status. Mühlemann bleeding index (Mühlemann H.R., Son S., 1971) [19] evaluated the bleeding. The study measured the intensity and extension of the inflammatory reaction by the cytological changes in the periodontium according to the Page and Schroeder model (Page R.C. and Schroeder M. E., 1976). The enzyme immunoassay kits from eBioscince determined the level of pro-inflammatory cytokines: interleukin (IL-1β), interferon-gamma (IFN-γ) and transforming growth factor (TGF-β1) in the oral fluid; and the anti-inflammatory cytokine, receptor antagonist interleukin IL-1 (IL-1ra), was measured using Invitrogen kit in strict accordance with Multiskan FC microplate photometer instructions (Thermo Scientific).Results. Children periodontal status evaluation did not reveal any pronounced clinical manifestations of the inflammation that could cause concern and complaints of bleeding gums. Thus, the Silness-Loe plaque index at the gingival margin was 1.70 ± 0.07 (control group 1.10 ± 0.03), the Mühlemann gingival sulcus bleeding index in children with undifferentiated connective tissue disease was 2.10 ± 0.05 (control group 0). The results of the oral fluid cytokine count in patients with undifferentiated connective tissue disease demonstrated a tendency for pro-inflammatory cytokine increase and anti-inflammatory cytokine decrease, in contrast to the control group.Conclusions. Thus, the qualitative composition of pro-inflammatory cytokines – interleukin (IL-1β), interferongamma (IFN-γ) and transforming growth factor (TGF-β1), interleukin IL-1 receptor antagonist (IL-1ra) in the oral fluid, in combination with clinical diagnostic methods in periodontal practice, can reliably predict the predisposition of people with undifferentiated connective tissue disease to periodontal inflammation and destruction. Medical checkup in children with undifferentiated connective tissue disease mainly aims to carry out comprehensive treatment and preventive measures to preserve the functions of the dental system. As children periodontal service is not allocated in the register of medical specialties in the Russian Federation, pediatric periodontal patients are followed-up in the periodontally healthy groups. However, it is evident today that periodontal passports are necessary, which indicate a genetic predisposition to inflammatory periodontal diseases.

Pro-inflammatory cytokines and anti-inflammatory cytokines are important mediators that regulate the inflammatory response in inflammation-related diseases. The aim of this study is to evaluate different New Zealand (NZ)-grown ginseng fractions on the productions of pro-inflammatory and anti-inflammatory cytokines in human monocytic THP-1 cells. Four NZ-grown ginseng fractions, including total ginseng extract (TGE), non-ginsenoside fraction extract (NGE), high-polar ginsenoside fraction extract (HPG), and less-polar ginsenoside fraction extract (LPG), were prepared and the ginsenoside compositions of extracts were analyzed by HPLC using 19 ginsenoside reference standards. The THP-1 cells were pre-treated with different concentrations of TGE, NGE, HPG, and LPG, and were then stimulated with lipopolysaccharide (LPS). The levels of pro-inflammatory cytokines, including tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), and anti-inflammatory cytokines, such as interleukin-10 (IL-10), and transforming growth factor beta-1 (TGF-β1), were determined by enzyme-linked immunosorbent assay (ELISA). TGE at 400 µg/mL significantly inhibited LPS-induced TNF-α and IL-6 productions. NGE did not show any effects on inflammatory secretion except inhibited IL-6 production at a high dose. Furthermore, LPG displayed a stronger effect than HPG on inhibiting pro-inflammatory cytokine (TNF-α, IL-1β, and IL-6) productions. Particularly, 100 µg/mL LPG not only significantly inhibited the production of pro-inflammatory cytokines TNF-α, IL-1β, and IL-6, but also remarkably enhanced the production of anti-inflammatory cytokine IL-10. NZ-grown ginseng exhibited anti-inflammatory effects in vitro, which is mainly attributed to ginsenoside fractions (particularly less-polar ginsenosides) rather than non-saponin fractions.

Secondary edematous breast cancer (SEBC), T4b, has a poor prognosis. The aim of this study is to examine the balance in serum levels of pro-inflammatory (TNFά, IL-8) and anti-inflammatory (IL-4) cytokines in patients with SEBC before special treatment. Materials and methods. A total of 87 patients with breast cancer (BC) were examined before treatment: 42 patients with SEBC in T4bN0-3M0 stage and 45 BC patients in T3-4N1-3M0 stage without edema. The control group consisted of 15 patients with fibroadenomas. The serum levels of cytokines (IL-4, IL-8, TNFά) in the patients was determined using the enzyme-linked immunosorbent assay. Results. In the SEBC patients as compared to the patients without cancer, the serum pro-inflammatory cytokine (IL-8, TNFά) levels were significantly increased and the anti-inflammatory cytokine (IL-4) level was slightly increased in 22 %. In BC without edema, an imbalance was noted in favor of pro-inflammatory cytokines, but in SEBC it was more pronounced (31.6 versus 12.4 and 5.6 versus 3.2, respectively). Conclusions. In the majority of SEBC patients, there is an imbalance in the cytokine profile in favor of the pro-inflammatory cytokines (IL-8, TNFά). SEBC patients with elevated levels of both pro- and anti-inflammatory cytokines before treatment are the highest risk group of tumor progression and metastasis. Inhibition of the IL-8 effects or related CXC chemokines, TNFά, and others may have important consequences for the systemic treatment of SEBC.

Staphylococcus hyicus is the most common causative agent of exudative epidermitis (EE) in piglets. Staphylococcus hyicus can be grouped into toxigenic and non-toxigenic strains based on its ability to cause EE in pigs. However, the inflammatory response of piglets infected with toxigenic and non-toxigenic S. hyicus has not been elucidated. In this study, we evaluated the serum cytokine profile in piglets inoculated with toxigenic and non-toxigenic S. hyicus strains and recorded the clinical signs in piglets. Fifteen piglets were divided into three groups (n = 5) and inoculated with a toxigenic strain (ZC-4), a non-toxigenic strain (CF-1), and PBS (control), respectively. The changes in serum levels of cytokines (interleukin [IL]-1β, IL-4, IL-6, IL-8, IL-10, IL-12, granulocyte-macrophage colony-stimulating factor, interferon-γ, transforming growth factor-β1, and tumor necrosis factor-α) were evaluated using a cytokine array at 6, 24, 48, and 72 h post inoculation. The results showed that piglets infected with the toxigenic strain exhibited more severe clinical signs and higher mortality than those infected with the non-toxigenic strain. The serum levels of pro-inflammatory cytokine IL-1β were significantly increased in toxigenic-and non-toxigenic-strain-infected piglets compared to those in the control group (p < 0.05), while the anti-inflammatory cytokine IL-10 was significantly up-regulated only in toxigenic group than in control group (p < 0.05). These results indicated that piglets infected with toxigenic and non-toxigenic S. hyicus showed differential infection status and inflammatory responses. Both toxigenic- and non-toxigenic- S. hyicus infection could induce a pro-inflammatory reaction in piglets. In addition, the toxigenic strain induced a strong anti-inflammatory response in piglets as indicated by the increased serum level of IL-10, which may be associated with the severe clinical signs and increased mortality and may be the key cytokine response responsible for pathogenic mechanisms of S. hyicus.

Kingella kingae is a Gram-negative coccobacillus belonging to the Neisseriaceae family. In children less than 4 years old, K. kingae invasive infection can induce septic arthritis and osteomyelitis, and more rarely endocarditis, meningitis, ocular infections, and pneumonia. In adults, it may be a cause of endocarditis. To date, K. kingae acute chorioamnionitis (AC) leading to preterm rupture of membranes (PPROM) and miscarriage has never been reported. Herein, we describe a case of intrauterine fetal death (IUFD) at 22 weeks’ gestation due to K. kingae infection occurred in a patient affected by undifferentiated connective tissue disease (UCTD) in lupus erythematosus systemic (LES) evolution with severe neutropenia. K. kingae was isolated in placental subamnionic swab and tissue cultures as well as fetal ear, nose, and pharyngeal swabs. Placental histological examination showed necrotizing AC and funisitis. In the fetus, neutrophils were observed within the alveoli and in the gastrointestinal lumen. Maternal medical treatment for UCTD was modified according to the K. kingae invasive infection. In the event of IUFD due to AC, microbiological cultures on placenta and fetal tissues should always be carried out in order to isolate the etiologic agent and target the correct medical treatment.

Using transcriptomics, anatomical studies, imaging and ELISA, Morin-Brureau et al. examine microglia in patients with temporal lobe epilepsies. In highly sclerotic regions such as CA1, the anti-inflammatory cytokine IL-10 regulates microglial phenotype. Seizures induce a transient microglial phenotype associated with secretion of inflammatory cytokines including human CXCL8.

Background: Coenzyme Q10 is a well-known cofactor in the mitochondrial electron transport chain required for ATP production. Coenzyme Q10 is recognized as an intracellular antioxidant that protects cell membrane phospholipids, mitochondrial membrane protein, and plasma low-density lipoprotein against oxidative damage caused by free radicals. Diabetes and its complications have been related to increased levels of free radicals and systemic proinflammatory cytokines and to an abnormal lipid profile. The aim of this study was to investigate the effects of coenzyme Q10 supplementation on some cytokine levels in streptozotocin-induced diabetic rats.Materials, Methods & Results: In this study, 38 healthy, adult male rats were used. The rats were divided into 5 groups. All animals were housed in separated cages during the four weeks. The animals in group 1 was fed standard rat pellets for 4 weeks. It was administered at 0.3 mL corn oil intraperitoneally daily for four weeks in group 2 animals. The animals in group 3 was injected intraperitoneally with 10 mg/kg CoQ10 daily for 4 weeks. Group 4 was made diabetic by subcutaneous injections of streptozotocin at dose of 40 mg/kg in 0.1 M citrate buffer (pH 4.5) single daily dose for two days and group 5 was made diabetic by subcutaneous injections of streptozotocin at dose of 40 mg/kg in 0.1 M citrate buffer (pH 4.5) single daily dose for two days and then was injected intraperitoneally with 10 mg/kg CoQ10 daily for 4 weeks. During the experiment, three animals from group 4 and one animals from group 5 were died due to streptozotocin-induced hypoglycemia. At the end of the study, blood samples were taken from all animals. In these blood samples, IL-4, IL-6, IL-10 and TNF-α plasma levels were determined with ELISA using sandwich enzyme-linked immunosorbent method via commercial kits. In this study, IL-4 level as an anti-inflammatory cytokine significantly decreased (P < 0.05) with diabetes induction compared to control group level. IL-10 level in diabetic group was statistically different (P < 0.05) from control group level. CoQ10 application to diabetic animals improved the falling in IL-10 level of diabetic group (P < 0.05). IL-6 and TNF-α levels in diabetic group significantly increased (P < 0.05) in parallel with each other compared to control group levels. The same parameters were reduced (P < 0.05) by CoQ10 application in diabetic animals.Discussion: In this study, the occurred changes in pro- and anti-inflammatory cytokines with experimentally induced diabetes are expected results and these results are consistent with some studies related diabetes. These results may be considered to hazardous effects and inflammation caused by diabetes on liver, pancreas and other tissues. CoQ10 suppressed the increments in plasma pro-inflammatory cytokine levels, whereas it restored the reducing in anti-inflammatory cytokine levels arising due to diabetes. The obtained results from this study after CoQ10 application supported similar studies used CoQ10 application against deleterious effects of diabetes in animals and humans. Therefore, it is possible to say that CoQ10 may play important role in regulation of imbalance between inflammation markers in diabetes conditions and further studies are needed to clear the beneficial effects of CoQ10 treatment on the other inflammation markers in diabetes status.
