Mucin adsorbed by E. coli can affect neutrophil activation in vitro.

Bacteria colonizing human intestine adhere to the gut mucosa and avoid the innate immune system. We previously demonstrated that Escherichia coli isolates can adsorb mucin from a diluted solution in vitro. Here, we evaluated the effect of mucin adsorption by E.

[Serum values of cytokines in patients with ischemic heart disease and arterial hypertension.].

The studied levels of cytokines (levels of Pro-inflammatory cytokine - interleukin-1β, anti-inflammatory cytokine - interleukin-10, CD40 ligand (CD40L)) in patients with arterial hypertension and ischemic heart disease. Indicators of Pro-inflammatory cytokine - interleukin-1β and anti-inflammatory cytokine - interleukin-10 were significantly increased in patients with arterial hypertension and ischemic heart disease compared with values in healthy individuals. Elevated interleukin-1β and CD40L in patients with arterial hypertension and ischemic heart disease compared with values in healthy individuals indicate inflammatory process in the endothelium.

Effects of Standardised Fermented Papaya Gel on Clinical Symptoms, Inflammatory Cytokines, and Nitric Oxide Metabolites in Patients with Chronic Periodontitis: An Open Randomised Clinical Study.

The clinical efficacy of topical administration of standardised fermented papaya gel (SFPG), known to have antioxidant and anti-inflammatory properties, versus conventional therapy was evaluated in a group of 84 patients with moderate-to-severe periodontitis, randomly assigned to control group (n = 45) undergoing traditional pharmacologic/surgical protocols or to experimental group (n = 39), additionally treated with intragingival pocket SFPG (7 g) applications (15 min daily for 10 days). Patients undergoing SFPG treatment showed significant (P < 0.05), durable improvement of three major clinical indices of disease severity: reduced bleeding (day 7), plaque and gingival conditions (day 14), and consistent gingival pocket depth reduction (day 45).

Is there a Role For Antioxidants in the Prevention of Infection-Associated Carcinogenesis and in the Treatment of Infection-Driven Tumors?

Causative connections between infections and cancer are ascertained for several types of viruses, bacteria, and parasites. The mechanisms of cancer induction in chronically infected inflamed tissues strongly implicate oxygen- and nitrogen-centered reactive species, and an impairment of redox-sensitive molecular pathways involved in the tumorigenic transformation, tumor growth, altered immune defense, and in the mechanisms of tumor cell death and survival. Here, we briefly reviewed mechanistic data on carcinogenesis and tumor progression of three major infection-associated tumors, human papillomavirus-induced cervical cancer, hepatitis B virus-positive hepatocarcinoma, and Helicobacter pylori-positive gastric cancer.

Coenzyme Q(10), vitamin E, selenium, and methionine in the treatment of chronic recurrent viral mucocutaneous infections.

Objective: Host defense and latency determinants in viral recurrent dermatologic infections are not entirely understood, as conventional protocols are inadequate to achieve fast healing and relapse prevention. Endogenously produced oxygen/nitrogen reactive species (ROS/RNS) are essential for antiviral immune defense, while their excess may aggravate skin inflammation. Here, we sought a nutritional approach capable of controlling ROS/RNS balance to accelerate recovery and inhibit recurrences of two mucocutaneous chronic DNA-virus infections.

Wide-spectrum profile of inflammatory mediators in the plasma and scales of patients with psoriatic disease.

Psoriasis is a chronic recurrent inflammatory disorder of the skin. Clinical subtypes include psoriasis vulgaris (PV), psoriatic arthropathy, and erythrodermic psoriasis. Aim of this study was to analyse relevant inflammatory mediators in the plasma of patients with distinct subtypes of active psoriasis, and in the scales of mild-to-moderate PV patients, and correlation to disease severity.

Clinical and biochemical effects of coenzyme Q(10), vitamin E, and selenium supplementation to psoriasis patients.

Objective: The aim of the present study was to evaluate clinical effects of supplementation with antioxidants to patients with severe erythrodermic (EP) and arthropathic (PsA) forms of psoriasis.

Methods: Fifty-eight patients were hospitalized, treated by conventional protocols, and randomly assigned to four groups. Groups EP1 and PsA1 were supplemented with coenzyme Q(10) (ubiquinone acetate, 50 mg/d), vitamin E (natural alpha-tocopherol, 50 mg/d), and selenium (aspartate salt, 48 mug/d) dissolved in soy lecithin for 30-35 d.

[Concentration of proinflammatory and antiinflammatory cytokines in blood and wound of patients with odontogenic phlegmons].

Levels of IL-1beta, IL-6, TNFalpha, IL-10 and TGF-beta in blood and wound of 56 patients with odontogenic phlegmons in dynamic of infection process were expected. In accordance with known facts production of proinflammatory cytokines (IL-1beta, IL-6, TNFalpha in blood in acute phase of the inflammation process was much more intensive than in normal conditions. Increased proinflammatory cytokines generation led to significant raising of IL-10 concentration, but elevation of its level in blood was only at the 10-14 the days of therapy.

Wound-healing effect of papaya-based preparation in experimental thermal trauma.

Treatment with the phytopreparation from papaya accelerated wound healing and reduced the severity of local inflammation in rats with burn wounds. The effect of this phytopreparation can be related to an increase in the effectiveness of intracellular bacterial killing by tissue phagocytes due to the inhibition of bacterial catalase. Antioxidant activity of the preparation decreases the risk of oxidative damage to tissues.

Effect of cytokines on the level of free radicals in the blood of patients with systemic and local staphylococcus infection.

An increased extracellular production of free radicals with bactericidal activity does not improve the efficacy of intracellular digestion of Staphylococci. The amount of intracellular oxygen reactive species generated by the neutrophils from patients with an infectious condition has been found considerably decreased as compared to healthy donors. On the other hand, the excess of secretion of free radicals into the extracellular space leads inevitably to the adaptive increase of antioxidant enzymes and, as a result, to an increase in the total antioxidant capacity of the blood plasma.
