The authors studied the effect of selenium on the dynamics of immune system indicators in children with autoimmune thyroiditis. They examined 31 children (average age of 11.16 ± 0.59 years). Group I included 17 children who took selenium (100 μg per day for 6 months) along with the basic treatment. Group II (n=14) took L-thyroxin. The control group included 15 healthy children of the same age. The average level of selenium in children of Group I and II was 69.23 ± 1.52 μg / l at the beginning of the study, in the control group it was 114.8 ± 3.18 μg / l. Before treatment, children in Group I and II had T-cell suppression, the average level of all cytokines (especially TNF-α and IL-6) was significantly higher than in practically healthy children. The study demonstrated that the level of the thyroid tissue antibodies decreased significantly (p=0.001) with an increase in the level of selenium in the blood serum. By the end of the study the content of IgA (p=0.012) and IgG (p=0.044) in Group I, as well as the number of lymphocytes CD3 + (p=0.008), CD4 + (p=0.015), CD16 + / 56 + (p=0.010) significantly increased. The authors observed statistically significant decrease in the levels of TNF-α (p=0.028), IL-6 (p=0.002) and IL-1β (p=0.009) in children who took selenium in addition to the main treatment. Thus, the results of the study suggest that selenium in the complex therapy of autoimmune thyroiditis significantly reduces the titer of antithyroid antibodies and positively affects a number of important indicators of immune homeostasis in children.

THE AIM. To determine the concentration of natriuretic peptide in the blood serum in children with congenital malformations of the urinary system (CM US) and to compare with the activity of renin-angiotensin-aldosterone system (RAAS).MATERIALS AND METHODS.119 patients with CM US aged 3 to 18 years were examined. A control group of 10 clinically healthy children. 3 groups were assigned: group I – 55 children with  congenital vesicoureteral reflux, and group II – 34 children with  congenital hydronephrosis and ureterohydronephrosis, III group – 30 children with other forms of dysembryogenesis of the US. Following indicators were identified by ELISA in the blood: renin, aldosterone,  N – terminal propeptide natriuretic hormone (NT-рroВNР). RESULTS.NT-рroВNР, renin and aldosterone hyperproduction were diagnosed in 59,6%, 69,7%, 54.6 % of sick children relatively. Concentrations were higher in all variants of  malformations in comparison with the control group. Significant  differences were revealed in obstructive species, where arterial  hypertension (AH) was diagnosed more often. Patients with AH  recorded significantly higher concentrations of NT-proВNР and renin.CONCLUSION.The key point in pathological processes developmentand progression in the cardiovascular system and kidneys is the  activation of RAAS. The system of natriuretic factors is important in maintaining the compensated state of patients due to the blockade of RAAS.

There is evidence that berberine (BBR), a clinically relevant plant compound, ameliorates clinically apparent collagen-induced arthritis (CIA) in vivo. However, to date, there are no studies involving the use of BBR which explore its prophylactic potential in this model of rheumatoid arthritis (RA). The aim of this study was to determine if prophylactic BBR use during the preclinical phase of collagen-induced arthritis would delay arthritic symptom onset, and to characterize the cellular mechanism underlying such an effect. DBA/1J mice were injected with an emulsion of bovine type II collagen (CII) and complete Freund’s adjuvant (day 0) and a booster injection of CII in incomplete Freund’s adjuvant (day 18) to induce arthritis. Mice were then given i.p. injections of 1 mg/kg/day of BBR or PBS (vehicle with 0.01% DMSO) from days 0 to 28, were left untreated (CIA control), or were in a non-arthritic control group (n = 15 per group). Incidence of arthritis in BBR-treated mice was 50%, compared to 90% in both the CIA and PBS controls. Populations of B and T cells from the spleens and draining lymph nodes of mice were examined on day 14 (n = 5 per group) and day 28 (n = 10 per group). BBR-treated mice had significantly reduced populations of CD4+Th and CD4+CXCR5+ Tfh cells, and an increased proportion of Foxp3+ Treg at days 14 and 28, as well as reduced expression of co-stimulatory molecules CD28 and CD154 at both endpoints. The effect seen on T cell populations and co-stimulatory molecule expression in BBR-treated mice was not mirrored in CD19+ B cells. Additionally, BBR-treated mice experienced reduced anti-CII IgG2a and anti-CII total IgG serum concentrations. These results indicate a potential role for BBR as a prophylactic supplement for RA, and that its effect may be mediated specifically through T cell suppression. However, the cellular effector involved raises concern for BBR prophylactic use in the context of vaccine efficacy and other primary adaptive immune responses.

The aim of the work was to study the dynamics of changes in the immune system indices and antioxidant protection when fluoroquinolones are included in the treatment regimen for acute edematous pancreatitis. The study included 86 patients with a diagnosis of acute edematous pancreatitis. Group I (n=40) consisted of patients who received treatment according to national and local standards and protocols, group II (n=46) — patients who additionally received fluoroquinolones as part of a comprehensive treatment. The control group consisted of 48 conditionally healthy people in whom laboratory and instrumental diagnostics were carried out similarly to those in patients with acute pancreatitis. According to the purpose and objectives of the study, the state of the immune system and the antioxidant defense system was studied. In patients with acute pancreatitis, changes in the indicators of the immune status were revealed, manifested by the formation of a secondary immunodeficiency with the addition of an autoimmune component. The traditional scheme of pharmacotherapy of acute pancreatitis without the use of antibiotics made it possible to partially correct the indicators of immune status. The use of ciprofloxacin in the complex pharmacotherapy of acute pancreatitis contributed to the normalization of the studied parameters. Thus, the use of fluoroquinolones in the complex pharmacotherapy of acute pancreatitis made it possible to effectively normalize the state of the immune system, cytokine and antioxidant statuses.

The aim of this study was to investigate the role of human herpesvirus-6 (HHV-6) in autoimmune thyroiditis (AIT) development. We examined the possible involvement of HHV-6 gene expression encoding immunomodulating proteins U12 and U51 in AIT development and their role in the modulation of chemokine signaling. One hundred patients with autoimmune thyroiditis following thyroidectomy were enrolled in this study. Nested polymerase chain reaction (nPCR) was used to detect the HHV-6 sequence in DNA samples. Reverse transcription PCR (RT-PCR) with three different HHV-6 gene targets (U79/80, U51 and U12) was to detect active infection markers. HHV-6 load was identified using a commercial real-time PCR kit. Immunohistochemistry was performed to investigate the expression of the HHV-6 antigen and RANTES (Regulated upon Activation, Normal T Cell Expressed and Secreted) in thyroid gland tissue. Different commercial immunosorbent assay kits were used for the detection of RANTES, IFNγ, IL-6, and TNFα levels in the AIT patient group and controls. We detected 98% presence of the HHV-6 genomic sequence in AIT patients’ thyroid gland tissues. Markers of active HHV-6 infection (HHV-6 U79/80, U12 and/or U51 mRNA) were predominant in AIT patients’ thyroid tissue samples in comparison with the control group (56% vs. 6%). Evidence from immunofluorescence microscopy showed that HHV-6 can persist in thyrocytes and can interact with RANTES. Visual confirmation of the intense immunofluorescence signal of RANTES detected in thyroid tissues could indicate high expression of this chemokine in the thyroid gland. On the other hand, immunosorbent assays showed very low RANTES levels in AIT patients’ peripheral plasma. These results indicate that RANTES level in AIT patients could be influenced by HHV-6 activation, which in turn may aid AIT development.

PURPOSE: To compare the orofacial functions (chewing, swallowing and speech) in children with asthma and healthy children. METHODS: A cross sectional study including 54 children of both genders with ages between 7 and 10 years was conducted. Twenty-seven of these subjects composed the experimental group, and were subdivided into two severity levels of asthma: Group I - mild intermittent and persistent asthma; Group II - persistent moderate to severe asthma. Twenty-seven healthy children were included in the control group (Group III). Speech-language pathology evaluation used the adapted Orofacial Myofunctional Assessment Protocol. Adaptation consisted in the exclusion of the structural part of the test, since this was not the aim of the study. The structural part was excluded because it was not the aim of this study. RESULTS: It was found alterations in oral functions, with significant differences between the three groups. These alterations showed no correlation with asthma severity, since the highest rate of alterations was found in Group I (mild asthma). CONCLUSION: Regardless of the severity level, children with asthma have altered patterns of chewing, swallowing and speech.

Background: Non-alcoholic fatty liver disease (NAFLD) is one of the alarmingly rising clinical problems in the 21st century with no effective drug treatment until now. Taurine is an essential amino acid in humans that proved efficacy as a non-pharmacological therapy in a plethora of diseases; however, its impact on NAFLD remains elusive. The aim of the current study is to evaluate the protective mechanism of taurine in experimental steatohepatitis induced by junk food given as cafeteria-diet (CAF-D) in male albino rats. Methods: Forty adult male albino rats of local strain between 8-10 weeks old, weighing 150 ± 20 g, were divided into four equal groups: Group I (control group), Group II (Taurine group), Group III (CAF-D for 12 weeks) and Group IV (CAF-D +Taurine). CAF-D was given in addition to the standard chow for 12 weeks, where each rat was given one piece of beef burger fried in 15 g of sunflower oil, one teaspoonful of mayonnaise, and one piece of petit pan bread, weighing 60g/ piece. In the serum, liver function tests; ALT, AST, ALP, GGT and the lipid profile; TG, TC, HDL-C added to reduced glutathione (GSH) were assessed colorimetrically, while fibroblast growth factor (FGF)-21, adiponectin & interleukin (IL)-6 via ELISA. The same technique was used for the assays of the hepatic levels of FGF-21, silent information regulator (SIRT1), malondialdehyde (MDA),IL-10, tumor necrosis factor-α (TNF-α) as well as the apoptotic markers; caspase-3 and B-cell lymphoma (Bcl-2). Results: The cafeteria-diet induced steatohepatitis was reflected by significantly increased body and liver weight gain, elevation of liver enzymes; ALT, AST, ALP and GGT added to the dyslipidemic panel, presented as increased TC, TG, LDL-C and decreased HDL-C levels. The steatosis-induced inflammatory milieu, marked by elevated serum levels of FGF-21, IL-6, hepatic TNF-α, as well as reduced IL-10 and adiponectin, was associated with steatosis- induced hepatic oxidative stress, reflected by increased hepatic MDA and decreased GSH levels, along with stimulated caspase-3 and decline in BcL-2 hepatic levels. These pathological disturbances were significantly ameliorated by taurine supplementation and evidenced histopathologically. The cross talk between hepatic FGF-21 and SIRT1 and their association to the induced perturbations are novel findings in this study. Taurine's efficacy in restoration of hepatic structure and function is partially via the increase in SIRT1 and associated reduction of FGF-21. Conclusion: The findings of the current study prove the protective role of taurine in NAFLD via a novel role in the amelioration of FGF-21/ SIRT1 axis, which could be considered a new therapeutic target.

Olanzapine is an antipsychotic drug effective in the treatment of stress-associated psychiatric illnesses, but its effect on the spleen remains unclear. Vitamin C is essential for the optimum function of the immune system. We aim to investigate the effect of Olanzapine on spleen structures and to assess the protective effect of vitamin C. Forty adult male albino rats were divided into four groups: group (I), a control; group (II), rats were given vitamin C at 40 mg/kg body weight; group (III), rats were given Olanzapine at 2 mg/kg body weight; and group (IV), rats were given vitamin C and Olanzapine at the same dose of group (II) and group (III) for one month. The hematoxylin and eosin (H&E) of the olanzapine treated group showed focal areas of cellular depletion and a decrease in the size of the white pulp. The red pulp was expanded and showed marked congestion and dilatation of blood sinusoids. Cluster of differentiation 3 (CD3) was significantly reduced, however both tumor necrosis factor alpha (TNF-α), and vascular endothelial growth factor (VEGF) were significantly higher. The administration of vitamin C repaired structural and immunohistochemical changes via increased CD3 and decreased TNF-α and VEGF. Therefore, the oxidative and the inflammatory pathways may be the possible mechanisms underlying olanzapine immunotoxicity. Vitamin C exerted immune modulator and antioxidant effects against olanzapine.

ABSTRACT Obsessive compulsive disorder (OCD) is a neurobiological disease characterized with obsessions and compulsions. Obsessive compulsive disorder occurs with an autoimmune mechanism after Group A β hemolytic streptococcus (GABHS) infection. Tumor necrosis factor (TNF) is an important cytokine, as well as having an important role in the apoptosis mechanism of autoimmune diseases. It is expressed by the TNF-α gene. The aim of this study was to examine the relationship between the TNF-α gene promoter region -308 (G>A) and -850 (C>T) polymorphisms and OCD. In this study, ages of the OCD patients and the control group ranged between 4 and 12 years. We studied two patient groups, one included childhood onset OCD patients (n = 49) and the control group was composed of healthy children (n = 58). Patients were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorder (DSM-IV) criteria and with Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime (KSAD-S-PL) version. For identifying the polyorphisms, polymerase chain reaction (PCR), restriction fragment length polymorphism (RFLP) and polyacrylamide gel electrophoresis (PAGE) methods were used.For the -308 polymorphism, 45 of 49 OCD patients’ results were completed, and for the -850 polymorphism, 47 of 49 OCD patients’ results were completed. According to our statistical results, there is a positive relationship between OCD and the -308 polymorphism (p <0.001) but no association between OCD and the -850 polymorphism (p = 0.053). There is no positive relationship between antistreptolysin O (ASO) titers and the -308 polymorphism (p = 0.953) but there is an important significance between the -850 polymorphism and ASO (p = 0.010). There is no positive relationship between gender of patients and OCD (p = 0.180) and no positive association between ASO and gender (p = 0.467). According to our results, we hypothesize that we can propose the mutant AA genotype for the -308 polymorphism, and that the mutant CT genotype for the -850 polymorphism may be used as molecular indicators for OCD.

Abstract Objective. The aim of the present study was to investigate the presence of inflammatory mediators in rats with only periodontitis and periodontitis in a setting of hyper- and hypo-thyroidism and to analyze the correlative linkages between inflammatory mediators and thyroid hormones. Methods. White male 12–14 weeks old inbred rats (n=48) weighing 180–200 g were employed in the experiment. They were randomly divided into the following groups: Group I – control group, Group II – group with a model of periodontitis, Group III – group with a periodontitis in a setting of hyperthyroidism, and Group IV – group with periodontitis in a setting of hypothyroidism. The presence of tumor-necrosis factor-α (TNF-α) and interleukins IL-1β and IL-10 in the periodontal homogenate supernatant was studied by a solid-phase enzyme-linked immunosorbent assay. Results. It was shown that experimental lipopolysaccharide (LPS)-induced periodontitis is accompanied by hyperproduction of pro-inflammatory cytokines (TNF-α, IL-1β) and reduction of anti-inflammatory cytokines (IL-10), whereas TNF-α underwent to maximum changes. Thyroid dysfunction exacerbates cytokine imbalance and severity of inflammation in experimental LPS-induced periodontitis, especially pronounced at hyperthyroidism, as evidenced by the predominance of TNF-α and IL-1β levels in the periodontal homogenate supernatant by 38.5% (р<0.01) and 75.6% (p<0.001), respectively, hyperthyroid over the euthyroid, and by 20.1% (p<0.05) and 24.1% (p<0.05), respectively, over the hypothyroid rats. Conclusions. Thyroid dysfunction, especially hyperthyroidism, may play an important role in the pro-inflammatory response in periodontitis. Hyperproduction of inflammatory mediators in thyroid dysfunction can induce a noticeable damage in the whole apparatus of the periodontium, thereby causing progression of periodontitis.

The aim of the study was to assess the level of blood neuron specific enolase (NSE) in children with chronic gastroduodenitis (CGD) depending on Hеlicobacter pylori (HP), the severity of the inflammatory process, sex. The study involved 73 children with CGD. Group I– children with CGD associated with HP (HP CGD+); group II – with CGD not associated with HP (CGD, HP–). The control group (GK) – 28 healthy children. In the diagnosis of the disease, the endoscopic and morphological methods were used; the urease, microscopy, molecular biological and serological tests were performed to verify HP. The elevated levels of NSE were revealed in children groups I and II compared with GK (p < 0.01, p < 0.01). High levels of NSE in serum were observed in boys with CGD HP+ compared with girls with CGD HP+ (p < 0.01). Similar changes related to the gender were identified in group II (p < 0.01). In group I the highest values of NSE were identified with erosive gastroduodenitis (p < 0.01). In group II the opposite direction of enzyme changes was revealed and depended on the severity of the disease. Тhe increase of NSE in the blood of children with CGD HP+ and HP-indicates the presence of enzyme in the mechanisms of the inflammatory process in the mucous membrane gastroduodenal area outside the continuum of HP-infection. A multidirectional character of NSE changes depending on the characteristics of lesions mucous membrane gastroduodenal zone in groups I and II does not exclude the NSE involvement into the mechanisms of formation of the severity of the disease. Higher levels of NSE in boys as in CGD, HP+ and HP – do not exclude the relations of NSE and sex hormones.
