This study investigated the effects of supplementation with Krill oil on levels of pro-oxidant/antioxidant balance markers and levels of pro-inflammatory cytokines in professional rowers submitted to exhaustive exercise.This double-blind study included 17 members of the Polish National Rowing Team. Subjects were randomly assigned a supplemented group (n=9) which received two capsules (500 mg) of Krill oil daily for 6 weeks, or a placebo group (n=8). At the beginning and at the end of preparatory camp, subjects performed a 2000 m maximum effort test on a rowing ergometer. Blood samples were taken from the antecubital vein prior to each exercise test, 1 minute after completing the test, and after 24-hours of rest. The following redox parameters were assessed in erythrocytes: superoxide dismutase (SOD), glutathione peroxidase (GPx), and thiobarbituric acid reactive substances (TBARS) concentration. Additionally, creatine kinase (CK) activity was measured in plasma samples, while tumor necrosis factor (TNF-α) concentrations were measured in the serum.Exercise significantly increased values of SOD, TNF-α and TBARS in both groups, but recovery levels of TBARS were significantly lower in athletes receiving Krill oil compared with the control group.Based on these results we conclude that supplementation with Krill oil (1 g per day) in trained rowers diminished post exercise oxidative damage to erythrocytes during recovery, but had no effect on antioxidant enzymes, TNF-α and serum lipid profiles.

Ple iotropic proinflammatory cytokines, interleukin- 1 (IL-1) and tumor necrosis factor-α (TNF-α), involved in the regulations of various immune responses, inflammatory processes and hematopoiesis. In the present study, the expression levels of IL-1 and TNF-α were detected by enzyme-linked immunosorbent assay (ELISA). Following the cytokine blockade as a successful clinical therapy for autoimm une diseases such as rheumatoid arthritis, the patients are more susceptible to a variety of opportunistic infections. IL-1 and TNF-α may be useful predictive biomarkers of diseases and offer potential targets for therapeutic intervention of inflammatory diseases. However, our results showed that the plasma IL-1 level was significantly higher in women compared to men (69.5 ± 19.8 pg/ ml in men and 80.1 ± 19.5 pg/ml in women, respectively); the plasma levels of TNF-α were higher in men than women (20.8 ± 4.9 pg/ml and 18.7 ± 7.1 pg/ml, respectively). The significant gender difference of plasma interleukin-1 (IL-1) and TNF-α levels present in healthy adults in Jiangsu Province, China (P=0.002 and P=0.015, respectively), and may be as a hint for sex differences of susceptibility to many diseases and elementary immune response.

Neuroinflammation is a known factor in the pathogenesis of recurrent depressive disorders. Depression is accompanied by activated immune-inflammatory pathways including increased levels of TNFα, sTNFR1and sTNFR2.The purpose of this study was to analyse the TNF-α, TNFRSF1A and TNFRSF1B genes on both mRNA and protein levels in patients with rDD, and to investigate the relationship between TNF-α,TNFRSF1A and TNFRSF1B gene expression and cognitive performance. The study comprised 158 subjects: patients with recurrent depressive disorder (n=89) and healthy subjects (n=69). Cognitive function assessment was based on: Trail Making Test, The Stroop Test, Verbal Fluency Test and Auditory Verbal Learning Test. Both mRNA and protein expression levels of all genes were significantly higher in rDD subjects when compared to healthy controls. No statistically significant correlations were observed between the analysed variables in both the rDD group and the HS test group. The only exception was noticed in the HS test group, where increased expression of TNFRSF1A and TNFRSF1B gene negatively affected the performance of the AVLT test. However, statistically significant correlations between TNF, TNFRSF1A, TNFRSF1B mRNA gene expression levels and all the neuropsychological tests used in the survey for the entire group were observed. Conclusions: 1.The results of our study show increased expression of the TNF, TNFRSF1A and TNFRSF1B genes on both mRNA and protein levels in depression. 2. Elevated expression of TNF-α, TNFRSF1A and TNFRSF1B negatively correlates with cognitive efficiency: working memory, executive functions, attention, auditory-verbal memory, effectiveness of learning processes and verbal fluency.

Inflammatory response has been recognized as a central feature in the development and progression of atherosclerosis, and VSMCs (Vascular Smooth Muscle Cells) - the main cellular component of media, play an important role in this process. Many reports indicate that the biologically active vitamin D metabolite - 1,25-dihydroxyvitamin D3 (1,25(OH)2D3 = calcitriol), besides its well established role in calcium homeostasis, plays an essential role in the regulation of the inflammation process. The aim of this study was to determine the regulatory effects of calcitriol, applied at two supra-physiological doses (10 nM and 100 nM), in VSMC culture. Secretion of the pro-inflammatory cytokines, IL-6 and TNF-α, was significantly attenuated in calcitriol-treated VSMC culture, but the level of anti-inflammatory TGF-β was generally unchanged. Since in advanced atherosclerosis lesions several cell types, including VSMCs, overproduce the HSP70 chaperone protein, we also checked the effects of calcitriol on its synthesis. The presence of 1,25(OH)2D3 did not affect HSP70 synthesis under physiological conditions but the synthesis of HSP70 in VSMCs exposed to heat shock was significantly inhibited by calcitriol (=100 nM). We observed that 1,25(OH)2D3 induced SOD 1 activity, stimulated the expression of IκB-α, and did not influence the level of NF-κB-p65 in VSMCs. The results of our study suggest that 1,25(OH)2D3 may serve as a natural anti-inflammatory agent and may therefore play a beneficial role in the physiology of VSMC in some contexts of atherosclerosis.

Background. Asthma in the elderly patients is usually characterized by severe course and poor response to treatment. Both antibodies class E (IgE), intercellular adhesion molecules (ICAM-1) and tumor necrosis factor (TNF-α) plays an important role in the induction and the maintenance of allergic inflammation. The serum concentrations of these mediators may change during aging, which may further modulate the course of the disease in older patients. Objective. The aim of this study was to assess the levels of ICAM-1 (ICAM-1), TNF-a and IgE in serum of patients with asthma in relation to patients’ age, disease severity and atopic background. Material and methods. The study included 108 patients with asthma (67 at the age between 18-40 years, 41 aged 65-80 years) and 24 healthy people aged 65 - 80 years as a control group. After medical history physical examination all study participants underwent skin prick tests, spirometry and blood sampling for determination of the concentration of IgE, sICAM-1 and TNF‐a. Results. Severe asthma was more common in the elderly (34.1% vs 23.9%, p < 0.01). Total serum IgE (total IgE) levels were significantly higher in atopic patients, including a group of younger people compared to older people. The concentration of sICAM-1 in elderly patients is the same as in younger patients, increased with the severity of disease, but did not depend on the coexistence of atopy. The concentration of TNF-a in the serum of patients with asthma in the elderly was significantly higher than in younger patients and did not depend on the coexistence of atopy. Conclusions. The course of asthma in elderly patients may also depend on the different profile of inflammation in the airways and peripheral tissues expressed by a decreased production of IgE antibodies, persistent high expression of ICAM-1 and increased production of non-specific inflammatory mediators such as TNF-a. Despite the differences in the concentration of total IgE, allergic the later course of inflammation does not depend on the coexistence of atopy. Geriatria 2012; 6: 224-231.

Wstęp. Astma u chorych w podeszłym wieku charakteryzuje się zwykle cięższym przebiegiem i gorszą odpowiedzią na leczenie. Przeciwciała klasy E (IgE), cząsteczki adhezji międzykomórkowej (ICAM-1) i czynnik martwicy nowotworów (TNF-α) odgrywają istotną rolę w indukcji i podtrzymywaniu zapalenia alergicznego. Ich stężenia w surowicy mogą ulegać zmianie w czasie starzenia się, przez co mogą dodatkowo modulować przebieg choroby u osób starszych. Cel. Celem badania była ocena stężenia ICAM-1 (sICAM-1), TNF-a i IgE w surowicy krwi chorych na astmę w różnych grupach wiekowych z uwzględnieniem ciężkości choroby i podłoża atopowego. Materiał i metody. Do badania włączono 108 chorych na astmę (67 w wieku 18-40 lat, 41 w wieku 65-80 lat) i 24 zdrowe osoby w wieku 65-80 lat jako grupa kontrolna. Po zebraniu szczegółowego wywiadu i przeprowadzeniu badania przedmiotowego u wszystkich uczestników badania wykonano punktowe testy skórne, spirometrię oraz pobrano próbkę krwi w celu oznaczenia stężenia IgE, sICAM-1 i TNF -a. Wyniki. Astma ciężka występowała częściej u osób w podeszłym wieku (34.1 % vs 23.9%, p < 0.01). Całkowite stężenie IgE (cIgE) w surowicy było istotnie wyższe u chorych atopowych, w tym w grupie osób młodszych w porównaniu do osób w podeszłym wieku. Stężenie sICAM-1 u starszych chorych było takie samo jak w grupie chorych młodszych, wzrastało wraz z ciężkością choroby, lecz nie zależało od współistnienia atopii. Stężenie TNF-a w surowicy krwi chorych na astmę w podeszłym wieku było istotnie wyższe niż u chorych młodszych i nie zależało od współistnienia atopii. Wnioski. Przebieg astmy u chorych w podeszłym wieku może zależeć dodatkowo od odmiennego profilu zapalnego w drogach oddechowych tkankach obwodowych wyrażonego zmniejszoną produkcją przeciwciał IgE, utrzymującą się wysoką ekspresją ICAM-1 i zwiększoną produkcją nieswoistych mediatorów zapalnych jak TNF-a. Pomimo różnic w stężeniu cIgE, dalszy przebieg zapalenia alergicznego nie zależy od współistnienia atopii. Geriatria 2012; 6: 224-231.

INTRODUCTION Fibroids are the most common benign tumors of the female reproductive organ. In uterine myoma cells, a disturbed expression of some cytokines and growth factors is found. AIM OF STUDY The aim of the study was to evaluate IL-1 and TNF-α expression in uterine myomas and myometrium in women of different age. MATERIAL AND METHODS The studies included 60 women. The control was a group of 20 patients in whom there were no fibroidal changes. The subjects were both in the reproductive and menopausal age. 20 women of childbearing age with fibroidal changes in the uterus (under age 45, FSH < 30 mIU/ml) and 20 women with fibroids at menopausal age (age 45–56, FSH > 30 mIU/ml) also qualified for the study. Immunohistochemical studies were performed on the sampled material. In the examined tissue fragments, the optical density of cells expressing IL-1 and TNF-α was evaluated, which reflects the concentration of the immunocytochemical reaction product. RESULTS Expression of the studied cytokines was higher in the myoma and surrounding myometrium comparing to the uterine myometrium of healthy women. CONCLUSIONS Increased expression of cytokines at the edge of uterine myomas may be a signal of the appearance of new tumors. Therefore, use of the expression levels of IL-1 and TNF-α as a prognostic factor should be considered.

WSTĘP Mięśniaki macicy są najczęstszymi nowotworami o łagodnym charakterze żeńskiego narządu rodnego. W ich komórkach stwierdza się zaburzoną ekspresję niektórych cytokin i czynników wzrostu. CEL PRACY Celem badań była ocena ekspresji interleukiny-1 (IL-1) i czynnika martwicy nowotworu- (TNF-) w mięśniakach macicy kobiet w różnym wieku. MATERIAŁY I METODY W badaniach uczestniczyło 60 kobiet. Kontrolę czystą stanowiły pacjentki, u których nie stwierdzono zmian mięśniakowatych, zarówno w wieku reprodukcyjnym (10 kobiet), jak i okołomenopauzalnym (10 kobiet). Do badań zakwalifikowano 20 kobiet w wieku rozrodczym ze zmianami mięśniakowymi w macicy (poniżej 45 roku życia, FSH < 30 mIU/ml) oraz 20 kobiet z mięśniakami w wieku okołomenopauzalnym (45–56 rok życia, FSH > 30 mIU/ml). W badaniu immunohistochemicznym pobranych skrawków oceniono gęstość optyczną komórek z ekspresją IL-1 oraz TNF-α, która stanowi odzwierciedlenie stężenia produktu reakcji immunocytochemicznej. WYNIKI Ekspresja badanych cytokin w mięśniaku oraz otaczającym go miometrium w była wyższa niż w miometrium macicy kobiet zdrowych. WNIOSKI Zwiększona ekspresja cytokin na obrzeżu mięśniaków macicy może decydować o pojawieniu się nowych guzów, dlatego należy rozważyć wykorzystanie poziomu ekspresji IL-1 i TNF-α jako czynnika prognostycznego.

Introduction: Chronic obstructive pulmonary disease (COPD) is characterised by the airflow limitation as a consequence of progressive inflammatory response to inhaled noxious particles and gases, particularly cigarette smoke. Three factors play a main role in pathogenesis of the disease: inflammatory process, oxidative stress and imbalance between proteases and antiproteases. Recently there are some evidences that also extrapulmonary changes like cachexia, osteoporosis or depression are associated with COPD. The aim of the study was to access local and systemic inflammation in patients with COPD. Material and methods: The study group consisted of 23 patients with COPD during stable and exacerbation phase of the disease. As a control served 16 asymptomatic smokers. We investigated: 1) concentration of hydrogen peroxide (H2O2) and proinflammatory cytokines like TNF-a and IL-6 in expired breath condensate (EBC); 2) serum levels of TNF-a and IL-6. Results: It was showed that the level of H2O2 in EBC of patients with stable COPD was significantly higher as compared with healthy smokers. Additional significant enhanced in H2O2 exhalation was demonstrated during exacerbation of COPD. There was no difference in IL-6 concentration between the study groups (p>0,05). Discernible level of TNF-a in exhaled air was measured only in those with COPD exacerbation. Exhaled H2O2 correlated with FEV1% predicted value in patients with stable as well as with exacerbation phase of COPD. Also serum levels of TNF-a and IL-6 of patients with stable disease were higher compared to the values of healthy smokers. The serum concentrations of studied cytokines did not change significantly during exacerbation of COPD. Conclusions:Our results demonstrated the occurrence of local oxidative stress in patients with stable COPD. This process significantly increased during exacerbation of the disease. Besides of local reaction in respiratory compartment of patients with stable COPD we revealed systemic inflammatory process measured by serum levels of TNF-a and IL-6. Exhaled H2O2 correlated with lung function (FEV1% pred).

Wstęp: Przewlekłą obturacyjną chorobę płuc (POChP) charakteryzuje ograniczenie przepływu powietrza przez drogi oddechowe będące wynikiem nadmiernej reakcji zapalnej na wdychane pyły i gazy, głównie dym tytoniowy. W patogenezie tej choroby odgrywają rolę trzy czynniki: proces zapalny, stres oksydacyjny oraz zaburzenia równowagi pomiędzy proteinazami i antyproteinazami. W ostatnich latach coraz więcej danych wskazuje na obecność u chorych na POChP zmian pozapłucnych, takich jak wyniszczenie, osteoporoza czy depresja. Celem pracy była ocena stanu zapalnego lokalnego oraz systemowego u chorych na POChP. Materiał i metody: Badania przeprowadzono u 23 chorych na POChP dwukrotnie - w stabilnym okresie choroby oraz w zaostrzeniu. Grupę kontrolną stanowiło 16 asymptomatycznych palaczy papierosów. Analizie poddano: 1) w kondensacie powietrza wydechowego (kpw) stężenie nadtlenku wodoru (H2O2) oraz proza-palnych cytokin TNF-α i IL-6; 2) w surowicy poziom TNF-a i IL-6. Wyniki: Stwierdzono, że u chorych na POChP w okresie stabilnym w kpw poziom H2O2 był znamiennie wyższy niż w grupie kontrolnej osób zdrowych. W trakcie zaostrzenia choroby ulegał on dalszemu wzrostowi (p<0,05). Natomiast stężenie IL-6 w powietrzu wydechowym było w badanych grupach podobne (p>0,05). Mierzalny poziom TNF-α zanotowano jedynie u chorych z zaostrzeniem POChP. Zarówno w okresie stabilnym, jak i w zaostrzeniu choroby poziom H2O2 w kpw korelował z FEV1% wartości należnej. Chorych na stabilną POChP charakteryzowało podwyższone w surowicy zarówno stężenie TNF-α, jak i IL-6 w porównaniu z grupą asymptomatycznych palaczy. W okresie zaostrzenia badane cytokiny nie ulegały istotnym zmianom (p>0,05). Wnioski: U chorych na POChP wykazano obecność lokalnego stresu oksydacyjnego, który w trakcie zaostrzenia choroby ulegał dalszemu znamiennemu nasileniu. Obok reakcji w kompartmencie oddechowym chorzy ze stabilną postacią POChP charakteryzowali się obecnością systemowej reakcji zapalnej mierzonej poziomem TNF-α i IL-6 w surowicy. Poziom nadtlenku wodoru w powietrzu wydechowym korelował z wartościami spirometrycznymi (FEV1% wartości należnej).
